In the second rice cooking control mode, the fully automatic rice cooking device body 1
With the control of the mechanical part of, the rice to be cooked is not weighed, and the washed rice and a predetermined amount of water are automatically put in the rice cooker, and the space between the fully automatic rice cooker body 1 and the automatic rice cooker 7 is increased. The data communication is carried out to input the control data for the amount of rice weighed and the control data for starting the rice cooking, and the rice cooking operation is started. For this reason, in this case, the enumeration determination during the rice cooking control is not performed, and the energization control of the heating power of the rice cooking heater is performed according to the rice cooking amount according to the control data received from the fully automatic rice cooking device body 1 by data communication. I do.

FIG. 6 is a flowchart showing an outline of the flow of rice cooking control of the rice cooking control circuit 60. This will be described with reference to FIG.

When the rice cooking control circuit 60 of the automatic rice cooker 7 is powered on, the microcomputer of the rice cooking control unit 61 of the rice cooking control circuit 60 performs an initialization process such as an initial reset. judge.
That is, it is determined whether the above-mentioned rice cooking control in the first rice cooking control mode (non-automatic) or rice cooking control in the second rice cooking control mode (fully automatic). If it is not determined to be fully automatic in step 70, it waits for a rice cooking start instruction from the display input section 66 of the rice cooking control circuit 60 in the automatic rice cooker 7, so the process proceeds to step 71 and the rice cooking start switch is turned on. Is determined. Step 71
If it is not determined that the rice cooking start switch is turned on, the process returns to step 70 and the process from step 70 is repeated.

In addition, when it is determined in step 70 that it is fully automatic, the process proceeds to step 72, data is stored for the control data received by the data communication from the main body control circuit 50 of the fully automatic rice cooking device main body 1, and the next step is performed. In 73, the fully automatic memory indicating the above-mentioned second rice cooking control mode is set, and the process proceeds to the next step 74. In addition,
In step 70, it is determined to be fully automatic when the control data is received from the main body control circuit 50 of the fully automatic rice cooking device main body 1, and when the control data is received,
It is determined to be fully automatic.

In the next step 74, the water absorption process is performed. The water absorption process is a process of warming the water in the rice cooker so that the rice absorbs water sufficiently. Next, in step 75, it is determined whether or not 500 seconds have elapsed to determine the end of the water absorption process. In step 75, the process returns to step 74 and the process of the water absorption step of step 74 is repeated until 500 seconds is determined.

When the water absorption process is completed after 500 seconds have passed, the process proceeds to the next step 76, the rice cooking heater is turned on, and the temperature is raised to T0 ° C. which is the reference temperature for determining the rice cooking capacity. This T0
It is determined in step 77 whether or not the temperature reaches ℃. When it is determined in step 77 that the temperature is T0 ° C. or lower,
Returning to step 76, the rice cooking heater is continuously turned on.

If it can be determined in step 77 that the temperature exceeds T0 ° C., in step 78, it is determined whether or not the memory is a fully automatic memory (set). If it is not the full automatic memory, it is the first rice cooking control mode, and the rice cooking capacity is determined by this automatic rice cooker 7. Therefore, the process proceeds to step 80, and the sum determination is performed to obtain the rice cooking capacity data. After 100
Cook up to ℃. Then, the process proceeds to the next step 82, and in the process from step 82, the heating power is determined according to the rice cooking capacity, and the process is performed to continue boiling with the optimum heating power.

Further, when it is determined in step 77 that the temperature has exceeded T0 ° C., and when it is determined in step 78 that the memory is fully automatic, this is the second step in which rice cooking control is performed according to an instruction from the fully automatic rice cooking device body 1. In this case, it is not necessary to determine the rice cooking capacity because the rice cooking control mode is set. Therefore, the process proceeds to step 79 and the reference temperature for temperature determination is set to 100 ° C., and cooking is performed without performing the total number determination. That is, in step 79, if the temperature is 100 ° C., the process returns to step 76, and the rice cooking heater is continuously turned on. In this case, the rice cooking heater is continuously turned on in the loop of step 76 → step 77 → step 78 → step 79 → step 76. When it is determined in step 79 that the temperature exceeds 100 ° C., the process proceeds to step 81, in which a fully automatic memory data conversion process is performed. This is to convert the control data sent from the fully-automatic rice cooking device body 1 into the data of the same format as the data indicating the rice cooking capacity obtained by the process of sum determination (for example, the temperature rise time data according to the heat capacity). To do. Then, the process proceeds to the next step 82, and in the process from step 82, the heating power is determined according to the rice cooking capacity, and the process is performed to continue boiling with the optimum heating power. That is, the ranges of the rice cooking capacity data that are summed up by the determination processing of steps 82, 83, and 84 are determined by a, b, c, and d, and the determined ranges a, b, c, Depending on d, in step 85, step 86, step 87, and step 88, the energization control of the rice cooking heater by the heating power of the corresponding rice cooking heater A, rice cooking heater B, rice cooking heater C, and rice cooking heater D is performed. The heating control for maintaining boiling is performed.

Heating control to maintain such boiling keeps boiling,
The boiling state of the rice cooker continues, the rice absorbs water sufficiently, the water at the bottom of the rice cooker disappears, and the temperature of the rice cooker rises sharply until the temperature reaches 130 ° C. That is, this means that in step 89, the temperature of the rice cooker is 1
It is determined whether or not the temperature is 30 ° C. or lower, and while it is determined that the temperature is 130 ° C. or lower, the process returns to step 82 and the process from step 82 is repeated. For example, if the rice cooking capacity is determined to be in the range b in the processing for summation determination or the processing for fully automatic memory data conversion, this is determined in step 83, and in step 86 the rice cooking heater with the heating power of the rice cooking heater B is used. Then, in step 89, it is determined whether or not the temperature is 130 ° C. or lower, and heating control for maintaining boiling is performed. Until it is determined in step 89 that the temperature exceeds 130 ° C., step 89 → step 82 → step 83
→ Step 86 → The processing loop of step 89 is repeated. When it is determined in step 89 that the temperature exceeds 130 ° C., next, in step 90, the unevenness process is performed, and in the next step 91, the heat retention process is performed and the process ends. In addition, in the murmuring process of step 90, the 1st mumming process, the 1st additional cooking process, the 2nd muting process, the 2nd additional cooking process, etc. for a predetermined time are performed. Then, the heat retention step of the next step 91 is reached. Usually, the process of the heat retention process is continuously performed until the operation switch is instructed to cancel the heat retention.

Next, the operation of the main body control circuit 50 on the side of the fully-automatic rice cooking device main body 1 will be described.

7a, 7b, 7c, 7d, 7e,
And FIG. 7f is a flow chart showing the flow of rice cooking control of the main body control circuit 50.

First, refer to FIG. 7a. In step 101,
When the power is turned on, the current time is displayed in the next step 102. Next, in step 103, an initial reset is performed to reset the work register and the like to perform an initialization process. Next, in step 104, it is determined whether or not the menu switch (menu SW) and rice cooking switch (rice cooking SW) are simultaneously turned on. The determination process of step 104 is a determination process of whether or not to perform the test program process for maintenance. If the menu SW and the rice cooking SW are simultaneously turned on, the process proceeds to the test program process (105). Since the test program processing is not directly related to the present invention, its explanation is omitted here.

If it is determined in step 104 that the menu SW and the rice cooking SW are not simultaneously turned on, the process proceeds to step 106 and it is determined whether or not there is an error bit. If there is an error bit, error processing is performed in step 107 according to the content of the error bit, and the process returns to step 106 again to determine whether or not there is an error bit. If it is determined that there is an error bit again, in step 107 error processing is performed again according to the error bit. In this manner, the existence of an error bit indicating the content of the error generated here is sequentially determined (step 106), and the error processing corresponding to it is performed (step 107).

When it is confirmed in step 106 that there is no error bit, the process proceeds to step 108, and it is determined whether or not the process counter is cleared. If the process counter has not been cleared, the process proceeds to step 109 to perform a process counter destination search process. This process counter destination search process is for compensating for power failure. After checking for power failure, set failure, etc., the rice is cooked according to the content of the process count that progresses according to the overall progress of rice cooking process control. Perform processing to continue the process or error processing. When the return is ended in the subroutine of the process counter destination search processing of step 109, the processing from step 106 is performed next. If it is confirmed in step 108 that the process counter has been cleared, then the process proceeds to step 110 in FIG. 7b.

Please refer to FIG. 7b. Next, in step 110, process initial processing is performed. Process initial process,
This is a process for confirming whether or not moving members such as a control motor and an actuator are located at an initial position (home position) in each mechanical portion of the fully-automatic rice cooking device body 1. When each moving member is not located at the initial position, in the process of this process initial, the drive for moving each moving member to the initial position is performed. When the process initial in step 110 is completed, the process proceeds to step 111, and a process of determining whether or not the process initial is abnormal is performed. When it is determined in the process of step 111 that the process initial is abnormal, the process returns to step 106. If there is no abnormality in the process initials, the process proceeds to the next step 112, the process of checking the state of the rice cooker is performed, then in step 113, it is determined whether or not the clock switch is turned on, and the clock switch is turned on. Only when it is determined, in step 114, the process of setting the current time is performed. Next, in step 115, it is determined whether the reservation switch is on. If the reservation switch is not on, it is then determined in step 116 whether the menu switch is on. If the menu switch is not on,
Further, in step 117, it is determined whether or not the heat retention switch is on. If the insulation switch is not on, then
The power failure confirmation processing of step 122 is performed, and step 11
Returning to 0, the process from the process initial of step 110 is repeated.

Further, when it is determined in step 115 that the reservation switch is turned on, it is determined in the next step 120 whether or not the pan is removed and the memory set is set. If the pan is removed and the memory is set, proceed to step 121 to notify the error,
In the next step 122, a power failure confirmation process is performed, and the process returns to step 110.

If the pan is removed in step 120 and the memory is not set,
Since it can be confirmed that the rice cooking pot has been pulled out once and washed normally, after confirming this, step 123
In step 124, the amount of stored rice is checked, and in step 124, the amount of water is checked, and in step 125, it is determined whether there is an error. If there is an error, step 106 (7a
Returning to the figure), the processing from step 106 is performed again. If there is no error in step 125, the blinking process of the previous course is performed in step 126, and step 146
Proceeding to (FIG. 7d), the processing in the reserved rice cooking mode from step 146 is performed.

On the other hand, in the determination processing of step 117, if it is determined that the heat retention switch is on, heat retention is in progress (118;
Proceed to the process of FIG.

If it is determined that the reservation switch is not on and the menu switch is on in step 116, the process proceeds to step 119, and the fully automatic rice cooking control is performed in the immediate operation mode instead of the reservation mode. In order to perform the processing of (1), the processing proceeds to menu selection processing described later. That is, in step 119, it is determined whether or not the pan is removed and the memory set is set. If the pan is removed and the memory is set, the process proceeds to step 121, an error is notified, and a power failure confirmation process is performed in the next step 122. , Step 11
Return to 0. Also, if the pan is removed in step 119 and the memory is not set, it can be confirmed that the rice cooking pan has been removed once and the rice cooking pan has been washed normally. After confirming this, in step 127 the amount of rice stored Check
Further, in step 128, the water amount is checked. Next, in step 129, it is determined whether or not there is an error.
If there is an error, return to step 106 (Fig. 7a),
The processing from step 106 is performed again. Step 129
If there is no error in step 130, next step 130 (Fig. 7c)
Proceed to.

Next, refer to FIG. 7c. In the case of performing the process of the fully automatic rice cooking control mode of the immediate operation mode, the process of selecting a course is performed in step 132. This course selection process is a process of selecting a course for the operation of each rice cooking process in the fully automatic rice cooking control.

As shown in FIG. 3, the course selection process is clear when selecting the menu for cooking rice.
There are 5 types of menu selections: cooked rice, 1 rice porridge, and 2 rice porridge. When selecting the amount of cooked rice, 1 from 2 cups
Select the amount of cooked rice for each cup up to 0 cups. In addition, the degree of "hardness" of cooked rice is selected from "hard" to "soft" in 10 steps. This "hardness" selection instruction gives instruction data of the amount of water addition and reduction when cooking rice. In addition, the degree of rice washing is set in three stages.

Returning to FIG. 7c again and continuing the explanation, step 13
When the process of selecting the second course is completed, next step 13
The process for confirming the set defect of 3 is performed. The process for confirming the set defect is a process for confirming whether or not the rice storage weighing unit, the rice washing unit, the rice cooking unit, the automatic rice cooker of the rice cooking unit, etc. are set in the normal position. Step 13
In step 3, when the processing for checking the set defect is completed, the process proceeds to step 134, and it is determined whether or not the cancel switch is turned on. If it is determined that the cancel switch is on, the process proceeds to step 135, the course LED (course display light emitting diode) of the operation display panel is turned off, and then the process counter is set to (00) in step 136. In order to start the process from the beginning, step 106
Return to. If it is not determined in step 134 that the cancel switch is on, the process proceeds to step 137, and it is determined whether there is a setting failure. If there is a set defect here, step 1
Returning to step 31, the processing from the power failure confirmation in step 131 is performed. If there is no set defect, it is determined in step 138 whether the reservation switch is turned on. here,
If it is determined that the reservation switch is ON, the operation is switched to the reserved rice cooking mode, so the process proceeds to step 146 to perform the fully automatic rice cooking control processing in the reserved rice cooking mode.

If the reservation switch is not determined to be on in the determination process of step 138, the process proceeds to step 139, and it is determined whether or not the start switch is turned on. If it is not determined that the start switch is on, the process returns to step 131, the processing from step 131 to step 139 is repeated, and the start switch is turned on. When it is determined in step 139 that the start switch is on, the process proceeds to the next step 140, and rice cooker communication processing is performed. The rice cooker communication process here is a process for confirming that the full-motion rice cooker 7 is set in the rice cooker unit 4. Next, in step 141, the gantry is locked, and in the next step 142, it is determined whether or not there is a lock abnormality. If it is determined in this determination that the gantry lock is abnormal, in step 143, the course LED on the operation display panel is turned off, and the process is restarted from the beginning. Therefore, the process returns to step 106. Also,
If no lock abnormality is determined in the determination in step 142,
In step 144, the course data is stored, and in the next step 145, the course LED is turned on. Then, after step 145, step 1 in FIG.
Proceeding to 72, the process of measuring rice from step 172, washing process, etc. is continued.

On the other hand, following step 126 in FIG. 7b or branching from the determination step in step 138 in FIG. 7c,
The processing in the reserved rice cooking mode from step 146 of FIG. 7d is continued.

Referring to FIG. 7d, first, step 146
Flashes reservation 1 or 2 and then step 14
At 7, the reserved time and the cooked display blink. continue,
The power failure is confirmed in step 148, the time is set in step 149, and the course selection process is performed in step 150. Next, in step 151, a set defect is confirmed, and in the next step 152, reservation switching processing is performed. Next, in step 153, it is determined whether or not the cancel switch is turned on due to an incorrect reservation setting, etc., and if the cancel switch is turned on, the process proceeds to step 154 to turn off the blinking display, Then, in step 155, the process counter is set to (00), and the process from the beginning from the error check is performed. Therefore, the process returns to step 106.

If the cancel switch is not determined to be on in step 153 and the reservation time, course selection, etc. are set, it is then determined in step 156 whether or not there is a set defect, and the set contents are consistent. After confirming that it is valid, in step 157, it is determined whether or not the start switch for starting the operation of the reserved rice cooking mode is turned on. If the start switch is turned on, the process proceeds to step 158, the reserved time is compared with the current time, and it is checked whether the set reserved times are consistent. If the reservation times are inconsistent, step 159
Then, the voice output of "Cannot reserve" is output, the process returns to step 148, and the reserved rice cooking mode setting process from step 148 is performed again. The process of resetting the reserved rice cooking mode by returning to step 148 is performed in step 156.
If it is determined that the start switch is not turned on when it is determined that there is a setting failure in step 14,
Returning to step 8, the reservation rice cooking mode is reset.

If the reservation time is checked (appropriate) in the check determination of the reservation time in step 158, the process proceeds to step 160, and rice cooker communication processing is performed. The rice cooker communication process here is a process for confirming that the fully automatic rice cooker 7 is set in the rice cooker unit 4. Next, step 16
In step 1, the pedestal lock process is performed, and the next step 1
At 62, it is determined whether or not there is a lock abnormality. If it is determined in this determination that the gantry lock is abnormal, in step 163, the blinking display is turned off, and the process from the beginning from the error check is performed.
Return to. If no lock abnormality is determined in the determination in step 162, the process proceeds to step 164 to store the course data, and in the next step 165, the reservation time and the cooking completion display are turned on. Then step 166
In, the reserved LED and the course LED are turned on. Then, in step 167, the processing within the reservation timer (processing of the subroutine) is performed.

In the subroutine of the process in the reservation timer, the content of the process counter is set to (02) indicating that the reservation timer is in progress, and while confirming the power failure, it is monitored whether the current time is the reservation time, It returns when it becomes.

When the processing in the reservation timer ends and the reservation time comes, next, in step 168, the reservation LED, the reservation time, and the display of the cooked rice are turned off. Next, in step 169, it is determined whether or not the end of the reservation is due to the cancel switch being turned on. If the end of the reservation is due to the cancel switch being turned on, the process proceeds to step 170, the course LED is turned off, and the step 1
In step 71, the process counter is set to (00), and step 1 is performed in order to perform the processing from the beginning from the error check.
Return to 06.

If it is determined in step 169 that the reservation is not completed due to the cancellation switch being turned on, the process proceeds to step 172 of FIG. 7e, and the rice preparation process such as the rice weighing process and the rice washing process is started from step 172. And continue.

With reference to FIG. 7e, the following rice preparation processing before starting the rice cooking operation will be described.

First, in step 172, the "washing rice" LED on the display is turned on, then in step 173, the slide backward (03) process is performed, and in the next step 174, it is determined whether or not there is an error in the previous slide backward process. judge. Next, in step 175, the lock cam operation (04) is performed, and in step 176, it is determined whether or not there is an error in the lock cam operation processing. Next, in step 177, the lid opening step (0
5) is performed, and in the next step 178, it is determined whether or not there is an error in the lid opening process. Then, in step 179, the lock cam storage (06) is performed, and next,
In step 180, it is determined from the detection output of the lid opening sensor whether the lid is opened normally. If the opening operation of the lid is not normally performed, the process proceeds to step 181, and in step 181, it is determined by the operation counter whether or not the opening operation of the lid is checked for the third time. If it is the third time or less, the process returns to step 175, and the opening operation of the lid is performed again by the processing from step 175. In addition, in the check of the opening operation of the lid in step 181, if the third check is exceeded, step 1
82, the error pit (08) is set, and the process proceeds to step 219 (FIG. 7f), which will be described later, and “under rice washing” L
The ED is turned off, and the processing of the step of washing rice ends in error.
Also, similar to the processing flow from step 182,
If the processing of the rice washing process ends in error, step 1
This is the case where it is determined in step 74, step 176, and step 178 that there is an error. Also in this case, similarly, the process proceeds to step 219, the "during rice washing" LED is turned off, and the processing of the rice washing step is ended in error.

If it is determined in step 180 that the lid opening operation has been normally performed, the process proceeds to step 192 to confirm that there is no error, and then step 19
In step 3, slide forward (07) processing is performed. In the next step 194, it is determined whether or not there is an error in the slide forward processing. Next, in step 195, the processing of the weighing step (08) of weighing rice for cooking rice is performed, and in the next step 196, it is determined whether or not there is an error in the processing of the weighing step. If it is determined in step 192, step 194, or step 196 of these error determinations that there is an error, the "during rice washing" LED is turned off in the same manner as described above, and the processing in the rice washing step is ended in error (step 219). 7f
Figure).

As a result, in the rice cooker unit 4, the automatic rice cooker 7 mounted on the carriage on the slide rail moves backward, the lid of the automatic rice cooker 7 is opened by the lid opening / closing mechanism 40, and the rice cooker 7 moves forward again to weigh and wash rice. It will be in a position where you can receive the cooked rice. Subsequently, the rice to be cooked is weighed by the rice storage weighing unit 2 and put into the rice in the rice washing device 30 of the rice washing unit 3. Then, the rice washing device 30 is controlled to wash the rice.

To control the rice washing device 30, first, in step 197, wash rice 1
Step (09) is performed, and in Step 198, one step of polishing rice (0
A), and then, in step 199, 2 steps of washing rice (0B)
Then, in step 200, a rice polishing process (0C) is performed. Next, in step 201, three rice washing processes (09) are performed. Subsequently, in step 202, overflow (0E) processing is performed, and when the rice washing processing is completed, the next step 203
The drainage process (0F) is performed at. When the rice washing process is completed by this series of processes, next, step 20 in FIG. 7f.
Proceed to step 4 of the rice removal process.

The description will be continued with reference to FIG. 7f. Then step 204
In step (10), the rice discharging process (10) is performed, and it is determined in the next step 205 whether or not there is an error in the previous slide reverse process. Next, in step 206, the process of water addition / reduction process (11) is performed, and in step 207, it is determined whether or not there is an error in the process of the water addition / reduction process. Next, in step 208, tank cleaning (12) processing is performed, and in the next step 209, it is determined whether or not there is an error in the tank cleaning processing. Further, in the next step 210, the process of slide backward (13) is performed, and in step 211, it is determined whether or not there is an error. Subsequently, in step 212, the lid closing step (14) is performed, and then in step 213, the lid sensor detects the state of the automatic rice cooker to determine whether or not the lid is closed. If the lid is not in the closed state, the process proceeds to step 214, and in step 214, the action counter determines whether or not the closing action of the lid is checked for the third time. If it is the third time or less, the process returns to step 212, the lid closing process of step 212 is performed again, and the lid closing state of the next step 213 is checked. If the lid closed state check in step 213 exceeds the third check, step 21
When the judgment is made in step 4, the process proceeds to step 215, the error pit (11) for displaying an error in this case is set, the process proceeds to step 219, the “during rice washing” LED is turned off, and the process of the rice washing process ends in error. To do. Then, in order to perform the processing from the beginning from the error check, step 106 is performed.
Return to.

If the lid closed state can be determined in the determination in step 213, the process proceeds to step 216, it is determined again whether or not there is an error, and then in step 217, the slide forward movement (1
The process of 5) is performed. Then, in the next step 218, it is determined whether or not there is an error in the slide forward processing. If it is determined in step 218 that there is an error, the process proceeds to step 219, the “during rice washing” LED is turned off, the processing in the rice washing step is terminated as an error, and the processing from the beginning from the error check is performed. Step 10
Return to 6. On the other hand, when it is determined in step 218 that there is no error, the process proceeds to step 220, the “during rice washing” LED is turned off, the series of processes during the rice washing process are finished, and the rice is cooked from the next time. Perform intermediate process.

By such control processing, after the rice is washed by the rice washing device 30, the washed rice is stored in the automatic rice cooker 7 located at the lower part of the rice washing device 30 with the lid open, and the rice is washed in a predetermined manner. Fill with water. Next, automatic rice cooker 7
, And the lid opening / closing mechanism 40 closes the lid of the automatic rice cooker 7 and moves forward again so that the steam generated during rice cooking can be discharged. Ends.

When the processing for preparing rice is completed by the control processing up to step 220, the processing during the rice cooking from step 221 is performed next.

In the subsequent process of the rice cooking process, first, step 22
In 1, it is determined whether or not the menu is cooked rice. When it is cooked rice, the operation to put the cooker in the rice cooker of the automatic rice cooker 7 is performed, so that the rice cooking control operation is temporarily interrupted. Therefore, in step 222, the "boiled rice" LED blinking process is performed, and in the next step 223, the process of waiting for restart (16) is performed.

In the restart waiting processing subroutine, the contents of the process counter are set to (16) indicating that the restart waiting processing is in progress, and while confirming the power outage and the setting failure, the user is instructed to the user at predetermined time intervals. Performs processing to generate a buzzer sound that draws attention. During this process, it is monitored whether or not the start switch is turned on. When the start switch is turned on, the defective set is checked again and the process returns.

The process of waiting for restart (16) of step 223 is performed, the rice cooking control operation is temporarily interrupted by this process, and while the user waits for the start switch to be turned on again, the user cooks rice with cooked rice. When you put it in the rice cooker and turn on the start switch, step 2
The process of step 23 is skipped and the process proceeds to step 224. Further, in the processing of determining cooked rice in the previous step 221, if it is not determined to be cooked rice, the process proceeds to step 224.

In the process of step 224, the "during rice cooking" LED is turned on to indicate that the process of the rice cooking process is started, and the process of cooking rice (17) is performed in step 225.

Although the processing during cooking rice (17) will be described later, rice cooker communication is performed, and an instruction to start cooking rice is transmitted to the automatic rice cooker 7,
The rice cooking operation is started, and the exhaust fan is controlled during this time to perform the steam and exhaust generated from the automatic rice cooker 7 during the rice cooking operation, and also to monitor the time, so that the rice cooking operation is completed and the rice can be eaten. The time until is displayed.

When the process of cooking rice in step 225 is completed, the "during cooking" LED is turned off to indicate that the process of the process of cooking rice is completed in the process of step 226, and the next step 2
At 27, it is determined whether or not there is an error in the process of cooking rice. If it is determined that there is an error, the process returns to step 106 to perform the processing from the beginning from the error check. If it is not determined that there is an error, the process of the next step 228 during heat retention (18) is performed.

As will be described later, the process during the heat retention (18) in step 228 is continued during the heat retention of the automatic rice cooker 7, and the exhaust fan is intermittently driven during this period. When the process during the heat retention is completed due to the cancellation switch being turned on, the occurrence of an error, etc., the process returns from step 106 to perform the process from the beginning.

In the main routine of the control processing flow of the fully automatic rice cooker body, the control processing for each mechanism and the processing of a typical subroutine for individual processing of each step will be described below.

FIG. 8a and FIG. 8b are flowcharts showing the processing of the subroutine of the processing for checking the set defect. This processing for confirming the set defect is frequently performed in the main routine of the control processing flow of the fully-automatic rice cooking apparatus main body, and the set state of each unit of the mechanical unit in the fully-automatic rice cooking apparatus main body 1 is confirmed. The result of the confirmation process performed in the set defect confirmation process is displayed on the rice cooking element device set display unit 17 in the display zone of one section on the operation display unit panel 5.
The fully automatic rice cooker main body and each symbol of each device unit are schematically displayed, and by each set confirmation display LED provided corresponding to the set position of the symbol of each device unit on the display section. Is displayed. From this, it is possible to easily discriminate what each of the device units is in the setting failure.

With reference to FIGS. 8a and 8b, the process of the set defect confirmation will be described. In this process, the set of automatic rice cooker,
Check each set defect of the rice cooker rail set position and the rice storage set position.

First, in order to confirm the state of the set of the automatic rice cooker, in step 301, it is determined whether or not the rice cooker communication is normally performed. If it is determined in step 301 that the rice cooker communication is normally performed between the fully-automatic rice cooker body and the automatic rice cooker, the automatic rice cooker 7 is set in the rice cooker unit 4, and the automatic rice cooker is further set. It is determined that the power plug 7 is plugged into the outlet and is electrically operable. If the rice cooker communication is OK in step 301, the setting state of the inner pot of the sensor of the automatic rice cooker 7 can be determined based on the contents of the rice cooker communication. Next, in step 302, it is determined whether or not the inner pot is present. To do. If there is an inner pot, it can be determined that the automatic rice cooker 7 of the rice cooker unit 4 is normally set, so in step 305, the "set defect position display" LED corresponding to the display position of the automatic rice cooker is displayed. Turn off the light. If it is not determined in step 302 that there is an inner pot, step 30
3, the "set defect" LED blinks, and then in step 304, the "set defect position display" LED corresponding to the display position of the automatic rice cooker blinks.

Next, check that the rice cooker rail set position is not properly set. Therefore, in step 306, it is determined whether or not the rice cooker rail set position is OK (normal position). If the rice cooker rail set position is OK, the process proceeds to step 309, and the "set defect position display" LED corresponding to the display position of the rice cooker rail set position is turned off. In addition, when the rice cooker rail set position is not determined to be OK in the determination in step 306, the process proceeds to step 307, the “set failure” LED flashes, and then step 30
In step 8, the "set defect position display" LED corresponding to the display position of the rice cooker rail set position blinks.

Then, the defective setting of the rice storage setting position is confirmed. Therefore, in step 310, it is determined whether or not the rice storage set position is OK (normal position). If the rice storage set position is OK, proceed to step 313,
The "set defect position display" LED corresponding to the display position of the rice storage set position is turned off. If it is determined in step 310 that the rice storage set position is not OK, the process proceeds to step 311, the “set failure” LED flashes, and then in step 312, the display goes to the rice storage set position. The corresponding "set defect position display" LED blinks.

As a result, it was possible to confirm the set defect of each position of the automatic rice cooker set, the rice cooker rail set position, and the rice storage set position, so set the "set defect" flag in the overall sense. Therefore, in step 314, it is determined whether or not all the “set defect position display” LEDs are turned off. All "set defect position display"
If the LED is not turned off, the process proceeds to step 315, the "set failure" flag is set, and the process returns to the main routine. If all "set defect position display" LEDs are off, step 3
Proceed to 16 and reset the "set failure" flag,
In the next step 317, the "set failure" LED is turned off, and the process returns to the main routine.

FIG. 9 is a flowchart showing the processing of a subroutine of the rice cooking processing. In the rice cooking process performed on the side of the fully-automatic rice cooking device body, rice cooker communication is performed, an instruction to start rice cooking is transmitted to the automatic rice cooker 7, and the rice cooking operation is started.
During this time, the exhaust fan is controlled so that the steam generated from the automatic rice cooker 7 during the rice cooking operation and the air are exhausted, and the time is monitored, and the time display until the rice cooking operation is finished and rice can be eaten is displayed. To do.

First, in this process, the process counter is set to (17) in step 401 to indicate that the process is in the process of cooking rice. Next, in step 402, the gantry lock process is performed, and then in step 403, it is determined whether or not there is a gantry lock abnormality. If there is something wrong with the gantry lock, it immediately returns to the main routine. In this case, the return is an abnormal return, not a normal return, so that in the main routine, as described above, the process during the rice cooking process ends, so the "during rice cooking" LED that indicates the end of the rice cooking process is turned off ( (Step 226), it is then determined that there is an error (step 227), and the process from the beginning starting from the error check process is performed (return to step 106).

If it is determined in step 403 that there is no gantry lock abnormality, then in step 404,
Rice cook start communication is performed to start the rice cook operation in the automatic rice cooker 7. As a result, in the automatic rice cooker 7,
The rice cooking control process is started according to the processing flow of the rice cooking control shown in FIG. In the fully automatic rice cooker, step 40
After performing the rice cooking start communication in step 4, the next step 405
After performing the power failure confirmation process in step S406, it is determined whether the rice cooker communication of the rice cook start communication performed in step 406 is OK. If there is no reception response in the rice cooker communication and the rice cooker communication is not OK, it is determined in the next step 407 whether or not the time is up, and if it is not,
Returning to step 405, the power failure confirmation processing and the rice cooker communication confirmation determination processing are repeated. Even if the predetermined time-up time has elapsed, there is no reception response of the rice cooker communication, the rice cooker communication is not determined to be OK, and when the time is up in step 407, the process proceeds to step 408 and the error state here. Error bit (E12) is set.
And, "after The "minute" display is turned off, and the process returns to the main routine. In this case, too, since it is not a normal return but an abnormal return, this causes the main routine to
As described above, since the process of the rice cooking process is completed, the "cooking rice" LED indicating the end of the process of the rice cooking process is turned off (step 226), and then it is determined that there is an error (step 227). , The process from the beginning is started from the error check process (return to step 106).

Further, in step 406, when the rice cooker communication reception response is received within the predetermined time-up time and it is determined that the rice cooker communication is OK, the automatic rice cooker 7 starts the normal rice cooker control operation. Therefore, in the next step 410, the exhaust motor is turned on, the exhaust fan unit is driven, and the exhaust of the steam generated from the automatic rice cooker 7 is started.

Next, in step 411, a power failure confirmation process is performed, and in the next step 412, in order to determine the cooked rice, it is determined whether or not the cooked cooked time display section indicates " 00 minutes left". "After 0, which indicates the time up cooking
If " 0 minutes" is not displayed, the process proceeds to step 413, it is determined whether or not the cooked rice menu is cooked,
If it is cooked, it is further determined in step 414 whether or not it is a purging process. If the rice-cooking menu is cooked and you have entered the Murashi process, proceed to step 415 Turn on the "minutes" indicator, then step 41
Returning to 1, the processing from step 411 is repeated.
If it is not determined in step 413 that the rice is cooked, or if it is not determined in step 414 that it is the uneven process, the process returns to step 411 and step 41.
The process from 1 is repeated.

If the cooked rice is cooked and it is judged in step 412 that the cooked time display is " 00 minutes left", the process proceeds to step 416 and the "after" Minutes'
Turn off the display. Next, in step 417, the process of the buzzer notification 3 is performed. Then, in step 418, it is determined whether or not the loop counter is 8 times. If it is not 8, the power failure is confirmed in step 419. The process of returning to step 417 is repeated. As a result, the process of the buzzer notification 3 is repeated eight times, and after the notification of the completion of cooking, the process returns to the main routine. In this case, the return is normal.

FIG. 10 is a flowchart showing a processing flow of a subroutine of heat retention processing. During the heat retention process performed on the main body of this fully automatic rice cooker, the process during rice cook is normally performed.
This is a process performed in response to the rice cooking operation of the automatic rice cooker 7 ending and the automatic rice cooker 7 entering the heat retention operation. The process during the heat retention is continued while the automatic rice cooker 7 is still warm, and the exhaust fan is intermittently driven during this period. When the cancel switch is turned on, an error occurs, or the like, the process during the heat retention ends, and the subroutine for the heat retention process returns. In addition, in the process of keeping warm, in the case of rice cooked with porridge, the heat-retaining lamp is lit to blink,
In the case of normal rice cooking, the heat-retaining lamp is continuously turned on to distinguish and display the condition of heat-insulated rice.

This will be described with reference to FIG. In this heat retention process,
First, in step 501, the process counter is set to (18) to indicate that the process during the heat retention is started. Next, in step 502, data set during heat retention is performed.
Next, the unit lock motor is turned off.
Next, in step 504, the exhaust motor is turned on, the exhaust fan unit is driven, and exhaust of the steam generated from the automatic rice cooker 7 is started.

Next, in step 505, it is determined whether the rice cooking menu is porridge rice. If the rice is rice porridge,
Proceeding to step 517, the heat retention lamp is blinked. Then, in the next step 518, it is determined whether or not the cancel switch is turned on. If the cancel switch is not on, the warming is continued, so the process proceeds to step 521, where it is determined at step 521 whether or not the rice cooker is initial, and at next step 522, it is determined whether or not the rice cooker is present. If it is determined in step 521 that the rice cooker is initial, and if it is not possible to confirm the presence of the rice cooker in step 522, the process during heat retention is ended, and the process proceeds to step 515.

In these determination steps, if there is a rice cooker instead of the rice cooker initial, the warming may be continued as it is, so the process proceeds to step 523, the fan intermittent drive process is performed in step 523, and the next step 524 is performed. Then, the power failure confirmation process is performed, and the process returns to step 518. Then, the processing from step 518 is repeated, and the processing during the heat retention in this case is continued.

When it is determined in step 518 that the cancel switch is turned on, the process during the heat retention is interrupted and ended. Therefore, the process proceeds to step 519, the heat retention cancellation process for the automatic rice cooker is performed, and the buzzer notification 1 is issued in the next step 520. Processing is performed and the process proceeds to step 515. Then, in step 515, the heat retention lamp is turned off, in step 516, the content of the process counter is set to (00), and the process returns to the main routine.

On the other hand, if it is determined in step 505 that the rice is not rice porridge, then in step 506, it is determined whether or not the automatic rice cooker 7 is kept warm. If it is not determined that the rice cooker is warm in this determination, an error (E12) is displayed in step 525, and then the warming lamp is turned on in step 507. In this case, since the rice is normally kept warm, the heat retaining lamp is continuously lit.

Then, in the next step 508, it is determined whether or not the cancel switch is turned on. If the cancel switch is not turned on, the process continues while keeping warm, so proceed to step 511, determine in step 511 whether it is a rice cooker initial, and in the next step 512 check if there is a rice cooker. judge. If it is determined in step 511 that the rice cooker is initial, or if it is not possible to confirm the presence of the rice cooker in step 512, the process during heat retention is ended, and the process proceeds to step 515.

Further, in the determination steps of step 511 and step 512, if there is a rice cooker instead of the rice cooker initial, the warming may be continued as it is.
3, the fan intermittent drive process is performed in step 513. Next, the power failure confirmation process of step 514 is performed, and the process returns to step 508. Then, the processing from step 508 is repeated, and the processing during the heat retention in this case is continued. When it is determined in step 508 that the cancel switch is turned on, the process during the heat retention is interrupted and ended. Therefore, the process proceeds to step 509, the heat retention cancellation process for the automatic rice cooker is performed, and the buzzer notification is issued in the next step 510. The process of 1 is performed, and the process proceeds to step 515. Then, in step 515, the heat retention lamp is turned off, in step 516, the content of the process counter is set to (00), and the process returns to the main routine.

FIG. 11 is a flow chart showing a process flow of intermittent fan drive performed in a subroutine of heat retention process. The intermittent fan drive process is a control routine for drive control of the exhaust fan unit. In this process, in step 601, it is determined whether or not 10 minutes have elapsed since the step (18) of the heat retention step was started, and if 10 minutes have not elapsed, the process immediately returns. If 10 minutes have passed after the step (18), the process proceeds to step 602, and the exhaust fan is driven in an intermittent drive pattern in which it is turned on for 10 seconds and turned off for 1 minute. .

As described above, the intermittent drive of the exhaust fan performed during the heat retention process is started after a predetermined time has elapsed since the control of the process during the heat retention was started. The driving period for driving is shorter than the rest period for stopping driving of the exhaust fan.

Therefore, in the process during the heat retention, the exhaust fan is intermittently driven to reduce the driving noise, and further,
The exhaust noise is reduced by operating with the exhaust capacity of the exhaust fan reduced.
