Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an electronically controlled cooking device such as an electronic cooker that controls heating using a microprocessor or the like.

(b) Prior Art In recent years, microwave ovens have been equipped with microprocessors that can perform various controls.

For example, as the first stage, 5
Microwave heating for 1 minute, then microwave heating for 10 minutes at 50% microwave power as the second stage, then leave the food in the cooking chamber for 6 minutes without heating (0% microwave power) as the 6th stage. Therefore, desired cooking can be performed. In such cooking, a cooking program consisting of microwave output and heating time for each stage, that is, cooking conditions, is set in advance, and a specific code is attached to the cooking program and stored in a predetermined storage section, and the above-mentioned cooking is executed. This is done by specifying the specific code and reading out the cooking program, and in this case, there is no troublesome setting of cooking conditions each time cooking, and the operability is extremely excellent.

Thus, during the course of cooking according to the preset cooking program, the cooking conditions of the cooking program can be modified in order to improve the finished product as judged from the progress of cooking. When the cooking program is modified, it is necessary to re-store the modified cooking program in the storage unit so that the same cooking can be repeated after the cooking is completed.

However, in this case, the cook must remember the contents of the correction, and resetting the cooking program is a bit of a hassle for the cook.

(c) Object of the invention The present invention aims to provide an electronically controlled cooker that allows easy setting of modified cooking programs and has excellent operability. The present invention is characterized in that the cooking according to the program is stored in the storage means along with the operation for making corrections during the cooking so that the cooking according to the program is repeatedly executed.

09 Example A microwave oven according to an embodiment of the present invention will be described below.

Figure 1 shows the appearance of the microwave oven.
A cooking chamber (21) is arranged in the cooking chamber (21).
The front opening of 2) is opened and closed by a door (3). Main body (1
) The control panel (4) on the front right side has a keyboard (5) for setting cooking conditions such as heating time, heating temperature, heating output, etc., and a fluorescent numeric display tube for displaying such cooking conditions, etc. (6) is provided, the details of which will be described later. A door latch (7) and a door switch knob (8) are protruded from the inner side of the door (3).
When the door is closed, these enter the main body and turn on the ink lock switch and the two door switches, respectively.

Further, a probe (11) having a needle-like insertion tip (9) and a plug (IG) is provided, and when the glove is used, the insertion tip (9) is inserted into the food, and the plug (l[)

The insertion tip (9) of the probe I has a built-in thermistor for detecting the temperature of the food, and the thermistor and the plug uC are connected by a shielded wire (X side).

Figure 2 shows details of the control panel (4), the fluorescent numeric display tube (6) having four digit numbers (6a) to (6d) and a colon (6e), each digit consisting of seven segments. . Furthermore, the keyboard (5) has 10 numeric keys from 0 to 9, TIME, TEMP, C00K, MEMORY,
CLEARl START.

It has a funk key, and each key is made up of a normal contact type push button switch.

FIG. 3 shows an electrical circuit diagram of the microwave oven.

Microwave generator (141 is interlock switch a9
, via the first door power aO and the two-way cyrisk rl force, it connects to the commercial power supply terminal [1a, It!J of 6Q) (z). Interlock switch 9 and first door switch (IG are turned on by the door latch (7) and door switch knob (8) described in FIG. 1, respectively, and bidirectional thyristor 07).
turns on when a voltage is applied to its gate through the 7-otocoupler I2. So microwave door (3)
When the photocube 2 is operated in the closed state, the magnetron generates microwaves, and the energy is supplied to the cooking chamber (2) of the microwave oven.

The gate (C) of the bidirectional thyristor θ'71 is connected to the power supply terminals C1,'J via the normally closed contact Q5! of the relay (241) on the other hand, and therefore the gate (C) is normally This prevents external noise from turning on the bidirectional thyristor ('lη). The normally open contact Cω of the relay is connected to the magnetron [2 (Il There is.

The above photocoupler (2 is the first and second transistor 08
1. Operates when both (2!D) are on, relay (2!
41 operates when the first transistor (281) is on, and its normally open contact f''e closes.

The control power supply section (3) is connected to the "λ" terminal na1tts via a step-down transformer I:I+i), and is distributed to each part of the circuit explained below. The heavy voltages VC and -VD, the heater voltage Vf to the display tube (6), and the 60H city voltage TB are applied, respectively.

Drive fl of the first and second transistor systems (2!)
'J control is performed by an output command from microprocessor G3.

Microprocessor 0 has many input/output terminals, and the following description will focus on these input/output terminals.

08 (1,08C2 terminals are microprocessor G4
This is a circuit constant connection terminal for oscillating the internal synchronized clock, and the coil and capacitor are externally connected.

ICi is an input terminal for inspecting the open state of the microwave oven door (3). That is, the terminal is connected to the second door switch G which is turned on by the door switch knob (8) described in FIG.
9 is connected, and when there is no input signal to the terminal IC1, that is, when the second door switch 351 is off, the microprocessor c33 recognizes the opening of the door [3J and suspends or prohibits its own operation. Determine necessity.

IC2 is an input terminal for checking the connection state of the globe αυ described in FIG. That is, a globe switch Gω which is connected to a jack provided on the wall of the cooking chamber (2) for connecting the valve I is connected to this terminal. This switch is turned on when the probe t1υ is connected to the above jack, and the microprocessor C37J is connected to the terminal I.
The connection state of the diglobe 0υ is determined based on whether or not an input signal is input to C2, and appropriate processing is performed.

RESET is an input terminal for resetting the microprocessor C to its initial state when the microwave oven is powered on. That is, when the power is turned on, the rising edge of the DC power supply voltage VC is detected by a detection circuit 07) such as a transistor and a Zener diode connected to the terminal RESET, and its detection output is input to the terminal RESET.

IT and OTl to OT4 are input/output terminals for temperature measurement. Microprocessor (3 are terminals OT1~OT
A 4-bit signal is output to 4, and the status of the 4 bits is changed to (0000), (0100), (1100) for each temperature measurement.
), . . . (1111) are changed rapidly in a binary manner. The states of the above 4 bits are defined at specific temperatures, such as ), COO00] at 185°F, and (1111
) correspond to 110°F, in 5°F increments. The above-mentioned 4-bit output is converted into an analog voltage by a group of resistors and an amplifier connected to each of the terminals OTi to OT4, and then inputted into the comparison mask. Of course, such analog voltage corresponds to the above temperature.

Between the comparators, there is a 7'
When the C voltage is input and the two input voltages match, a match signal is generated from the comparator, and this signal is input to the terminal IT. When the match signal is input to the terminal IT, the microprocessor 03 immediately stops the state change of the 4-bit signal. That is, the state of the 4-bit signal at this time corresponds to the food temperature detected by the globe αυ, so the microprocessor b INT is an interrupt terminal (, OHz signal TB is output from a transistor, diode, capacitor, etc. A waveform shaping circuit (shaped into a 60Hz pulse signal at 4α and sent to terminal IN
Enter T. Every time a 60 Hz pulse signal is received, the microprocessor 03 interrupts other processing and generates a second signal for executing time measurement processing as will be described later.

DSi to DS7 are data output terminals, and DG[ to DG5 are control signal output terminals, and the outputs of these terminals are input to the display tube (6) described above. Display is performed on the display tube (6) in a time-division manner.

Thus, each output of the terminals DGI to DG5 is generated sequentially,
The output signals of each terminal DG1 to DG4 are respectively 4-digit numerical part (
6a) to (6d) digit selection signal and none, one terminal DS1
The output signals of ~DS7 are used as segment selection signals for the numerical parts (6a) to (6d). Therefore, for example, end + DG
When the output of 2 is present, the terminals Dl, DS3, DS4, DS5
, DS7 are present, the number "2" is lit and displayed in the number section (6b). Also, the output signal of terminal DG5 is used as the digit selection signal of colon (6e), and the output signal of terminal D
The output signal of S1 is used as a colon selection signal, and therefore, when the output of terminal DG5 is present and the output of terminal DS1 is present, the colon (6e) is lit.

DG6 is an additional control signal output terminal, which is outputted to this terminal following the generation of the output of the terminal DG5, and such output is outputted to the key matrix (4) together with each output of the terminals DG2 to DG5.
1) is applied to the five column lines.

IK1 to IK4 are key signal input terminals, each of which is connected to four row lines of the key matrix (4υ).A keyboard (5) is connected to each intersection of the column lines and row lines that make up the key matrix (41). The key switches are cross-connected so that when a key is operated on the keyboard (5), the column line and row line forming the intersection point corresponding to the key are electrically connected via the key. The signal is input to the terminals IJ to IK4 that are connected to the row line.The microprocessor c3 therefore connects the terminals DG2 to D
The state of the input signals to the terminals IKi to IK4 is checked in synchronization with each output signal of G6 to determine whether the key operated by K is the key.

OM and OP are a heating instruction terminal and an output level instruction terminal, respectively. In the heating execution stage, the microprocessor β Enoki first generates an output signal to the terminal OM, and after a slight delay generates an output to the terminal OP, and then finishes the heating execution. Sometimes the way both terminals come out disappears. That is, the output from the terminal OM turns on the first transistor, drives the relay (241), and turns off and on the normally closed contact and normally open contact 4, respectively.

As a result, the gate (2) of the bidirectional current risk (lη) is released from the short-circuited state, and the blower motor (27) is driven.

Next, when an output is generated from the terminal OP, the second transistor C
When the bell hits, the shift coupler C is driven.

At this time, the output of the terminal OP has a cycle of 10 seconds, and within each cycle, it is generated for a period corresponding to the output level. Therefore, the microwave output generated by the magnetron (2Q) has a period of generation within one cycle. For example, if it is 10 seconds, it will be the maximum output value, and if it is 5 seconds, it will be 50% output value.

FIG. 4 shows a storage area (421) provided in the microprocessor C33, and the storage area includes R1 to R9 registers p, R'm1 to R', 5 registers (m: 1°2.
6. ...) and various hooks, etc., and heating time (or heating temperature) and heating output are encoded and stored in sections a and b of each register, respectively.

Next, the operation of the microwave oven will be explained based on a flow chart showing the flow of the operation program of the microprocessor 32 shown in FIG.

CI) After the power is turned on, the operating program is set to M in Figure 5a.
After passing through one step, steps M2 to M6 are cycled. In the M1 step, all rewritable areas in the microprocessor (3) are cleared and the same processor G2
The operation of canceling all outputs is performed. In step M2, the current operating key on the keyboard (5) is detected. Note that such key detection is performed only once as long as the key is not released and is continuously operated.
Further, if the previous key operation is not canceled and continues to be performed, nothing is performed. M6 to I'/I In the 6 steps, press the TIME key and TE key on the keyboard (5), respectively.
MP key, RECIPE key, 5TORE key is M1
It is determined whether or not it has been detected in step.

(11) Then, for example, as a first stage, microwave heating is performed for 5 minutes at a microwave output of 30%, then as a second stage, microwave heating is performed for 10 minutes at a microwave output of 509i1, and then as a sixth stage, heating is performed. When food is left in the cooking chamber (2) for 6 minutes (microwave output 0%) and the desired cooking is performed, the microwave output and heating time for each stage are 1! , W tg conditions, the order of key operations on the keyboard (5) is 1 ugliness b Ilh + i normal visit J Yoshu M n 2 old Taguchi 1 giant ℃ 5-' 1Yii Tsukasa Kabi.

First, when you operate the TIME cow, the operation program is l.
The cycle of steps 1a2 to t146 is exited by M steps and the TIME routine (FIG. 5b) is entered.

Upon entering the TIME routine, the operating program immediately cycles through steps A1-A6. A1 step is the current target register, in this case R1 register a.
The contents of the section are displayed on the display tube (6). Part a is now in a clear state and is displayed as 0. A2 step is M above
Similar to step 2, fi, step A5 determines whether or not a key was detected in step A2.

Then, when the number 5 key is operated, the operation program exits the cycle of steps A1 to A6 by step A6 and reaches step A4. In this step, it is checked whether the key detected in step A2 is a number. In this case, it is a number, and in the next step A5, r5J is written in the a part of the currently targeted register, currently the R1 register.

After that, the operation program cycles through steps A1 to A6, and then when the number 0 key is pressed twice, rOJ
rOJ is similarly written to part a of the R1 register, so that the contents of part a become P<[soo,J, representing the first stage heating time of 5 minutes.

In this case, the display will be "5", "50", etc. according to the key operation.
It changes sequentially to "s:oo".

Next, operate the C00K key and the operating program will be A.
Breaking out of the cycle of steps 1 to A6, passing through step A4, and moving to A6
Proceed to step. In this step, it is checked whether the key detected in step A2 is C00K. In this case C
Since it is the 00K key, the operating program is then C00K.
The routine (Figure 5C) is entered. If it is not the C00K key, the process proceeds to an appropriate step in which it is subsequently determined what kind of key it is.

When the C00K routine is entered, the operating program immediately cycles through steps B1 to B3.

In the B1 step, the contents of the b section of the currently targeted register, in this case the R1 register, are displayed on the display tube (6). At present, the square section is in a clear state and a zero is displayed. The B2 step is the same as the above M2 step, p,
In step B3, it is determined whether or not a key was detected in step B2.

Then, when the key number B is operated, the operation program exits the cycle of steps B1 to B3 from step B3 to step B4. In this step, it is checked whether the key detected in step B2 is a number. In this case, it is a number, and in the next step B5, "3" is written in the b section of the R1 register, which is currently the target.

After that, the operation program cycles through steps B1 to B3, and then when the number 0 key is operated, "0" is also changed to R.
1 is written to part b of register 1, so that the contents of part 1 represent 60% of the microwave output of the first stage.P<r3
It becomes 0J. In this case, the display will be r3J according to the key operation.
, r30J.

When the MEMORY key is then operated, the operation program exits the cycle of steps B1 to B6 and proceeds to step B6 via step B4. In this step, it is checked whether the key detected in step B2 is MEMORY. Since it is the MEMORY key in this case, the operation program then reaches step B7. Incidentally, if it is not the MEMORY key, the process proceeds to an appropriate step in which it is subsequently checked what kind of key it is.

In step B7, the routine enters the next target register, that is, the R2 register TIME routine next to the R1 register in this case.

Then, when you press the key ``Shiki Roro Nihon Shrine'' 31 (3j), the TIME routine changes the contents of part a of the R2 register to ff1ooo, J to represent the 10 minute heating time of the second stage. C, C0
0, the contents of part b of the R2 register become r50J to represent 50% of the second stage microwave cutting. In this case, the display on the display tube (6) will display rIJ, rloj, [1:OoJ, "10:00",
It changes sequentially from "5" to "50".

Next, when the MEMORY key is operated, the operating program reaches step B7 of the C00K routine, and the next target register, that is, the R3 register next to the R2 register in this case, is specified.

Then, by pressing the key 41 times, TIME will be displayed as ``600'' to indicate the heating time (leaving time) of the unit, as described above.
In the C00K routine, the contents of the b part of the R6 register are changed to the 6th
It becomes "0" to represent the microwave output θ coefficient of the stage. Incidentally, such an output 0 spell is originally entered in the clear state of part b, so there is no need to intentionally perform a key operation to set the above-mentioned output 0. In this case, the display tube (6)
The display will be "6", "6o", "6:" according to the key operation.
00" and "0" sequentially.

Here, in registers R1, R2, and R1, cooking conditions that constitute a cooking program, that is, heating time and microwave output, are stored corresponding to the first, second, and sixth stages, respectively, as shown in FIG. 6a. ing.

Therefore, in order to execute cooking using such a cooking program,
5 Operate the TART key. When you perform such key operations,
The operating program currently cycles through steps B1 to B6, skips one step to step B6, goes through steps B4 and B6, proceeds to the appropriate steps, and at step B2 the detection key is set to S.
The T ART key is checked and the operating program enters the 5TART routine (Figure 5d).

In the 5TART routine, the operating program is CI
, C2 steps, and then C5 and C6 steps. C1
The presence or absence of the RCP flag corresponding to step RECIPE cooking (details abj will be described later) is checked, and C2
In step C5, it is checked whether the 1NTR flag is set, which indicates that cooking is interrupted, and in step C5, the flag B, which indicates that cooking is in progress, is checked.
The USY flag is set and the lNTR flag is reset, and in step C6, the same contents as part b of the R1 register,
In this case, [Oj is also set in the b section of the R4 register.

In step <07, the remaining time for each stage is displayed on the display tube (6) based on the contents of section a of the R1 register. The next C8 step is similar to the M2 Nutep.

Next, in step C9, the presence or absence of a set of BUsY-y lags is checked. In this case, it is set, and in the following step C10, microwave oscillation of the magnetron is instructed based on the contents of part b of the R1 register.

That is, first, output is generated from the terminal OM, and then an output is generated from the terminal OP. In this case, since a width of 30 is set as the output, the output of the terminal OP is generated for only 6 seconds within each cycle, with 10 seconds being one cycle.

In the next C1l step, in order to count the elapsed time for each stage, the a part of the R4 register starts counting up from 0, and in the following C12 step, the a part of the R1 register starts to count the elapsed time for each stage. will start counting down from the current settings. Next C
In step 16, it is checked whether the contents of part a of the R1 register have become 0 or not. In this case, it is not 0, and the operating program proceeds to step C14. In this step, the presence or absence of the detection key in step C8 is checked, and now there is no key, so the operation program returns to step C7 p, c7 ~
Cycle C14x Tegg.

Here, we are currently in the first stage execution state.

Therefore, the progress status should be checked during such execution (STO
Operate the P key. L'E&N1 where such operation is performed? −// s= p +, J−/' 7 −− /'
4 J -y s-, Li -1Δ) 4-2 ring through step 014, step C15 to check whether the detection key at step C8 is 5TOP, and then proceed to steps 016 to C.
Proceed to step 19.

Incidentally, if it is not the 5TOP key, the process proceeds to an appropriate step in which it is subsequently checked what kind of key it is.

Then, in step C16, counting in part a of register 14R1 and part a of register R4 is stopped, and C1
In step 7, the microwave oscillation instruction is stopped,
At step C18, the BUSY flag is reset and C
The 1INTR flag is set in step 19.

After that, the operation program returns to step C7, and 07~
Cycle through steps C9 and C14. In such a circulation state, open the door (3j) to check the cooking status of the food, and if it is good, close the door (3) and immediately turn on the 5TAR.
Just use the T key.

Therefore, if you do not press the 5TART key and press 2, the operating program exits the cycle of steps C7 to C9 and C14 to steps CL4B4, and proceeds to the appropriate step via step C15.
It is determined that the detected key at the 8th step is the 5TART key, and in this case the operating program returns to the C1 step, passes through the C2 step, and then reaches the C3 step. In this step, it is checked whether the contents of section b of the R1 register and the contents of section b of the R4 register are the same. In this case, the contents of both are "6o" and the same, so the operation program passes through steps C5 and C6, then cycles through steps C7 to C14, and when the first stage is stopped midway (when the STOP key is operated). restarted from the state.

When the first stage heating time of 5 minutes (not including the intermediate stop time) has elapsed, the contents of the a part of the R1 register become 0 (the contents of the R1 to R4 registers become as shown in Figure 6). ), then) the 69 program will exit the cycle of steps C7 to C14 from the step C1, and move on to steps C16 and C1.
The process proceeds to step C21 through steps C16' and C17', which are similar to step 7, and step 020, which is similar to step C1. In this step, registers with small numbers in registers R5 to R9 are all cleared kH, in this case, registers a and b of register R5 and a1b of register R4.
The contents of the section are transferred (FIG. 6C).

In the following step C22, the presence or absence of the next stage is determined depending on whether parts a and b of the R2 register are both cleared.
In this case, the presence or absence of the second stage is checked, and since the second stage now exists, the operating program is 02ES.
Proceed to step. In this step, the contents of the registers corresponding to the next stage and subsequent stages are sequentially transferred to the registers corresponding to the previous stage (FIG. 6d). In this case, R1
The cooking conditions of the second and sixth stages are stored in the register R2 and the cooking conditions of the second stage and the sixth stage, respectively.

Thereafter, the operating program passes through steps cl, C2, C5, and C6 and cycles through steps C7 to C14, and the second stage is executed in the same manner as described above.

Then, when the heating time of the second stage of 10 minutes has passed, R
When the content of part a of register 1 becomes O (Fig. 6e), the operating program exits the above-mentioned circular state, and CI 6'
, C17', C20, C21 steps (Fig. 6 f)
), leading to steps C22 and C2'5 (Fig. 6g).

Similarly, the operating programs are cl, C2, C5, C.
After six steps, steps C7 to C14 are cycled, and the sixth stage is executed. When the heating time (standing time) of 3 minutes has elapsed, the operation program follows the same procedure and reaches step C21 (FIG. 6h). Subsequently, the operating program reaches step C22, but in this case there is no next stage, that is, the fourth stage, and then returns to step M2 through step C24, where the RCP flag is reset, and the cycle state of steps M2 to M6 is continued. to go into.

(1) If the above-mentioned cooking is to be repeated later, the cooking program must be stored in a predetermined area.

In this case, such a cooking program must be identified by an arbitrary cooking number, for example, cooking number 6, and the key operations are as follows: First, when the 5iTORE key is operated, the operating program cycles through steps M2 to M6. Escaped at step M6,
5Enter the TORE routine (Figure 5e).

In the s'roRE routine, in step D1, R
It is checked whether the a and b sections of the 5 register are both in the clear state. In this case, the R5 register contains part a K r5
"30" is stored in the 00J, b section, and the operation program then reaches steps D2 and D3. Incidentally, when the R5 register is in a clear state at step D1, the operation program reaches the appropriate step.

Then, in step D2, the cooking number,
That is, the contents of the number register are displayed. "O" is now displayed. The D6 step is similar to the above M2 step. Next, in step D4, the presence or absence of the detection key in step D6 is checked, and now there is no key, so the operating program returns to step D29 and cycles through steps D2 to D4.

Mu say %脣lha7-もすとふL Converter Godaram escapes from this cycle by step D4 and proceeds to step D5.
In this step, it is checked whether the key detected in the D3 step is a number, and in this case, the number is 9. Therefore, in the D6 step, "6" is set in the number register in the storage area (421).

The operating program then cycles through steps D2-D4. The cooking number "6" is displayed on the display tube (6).

Next, when the 5TORE key is operated, the operating program exits this cycle and goes through step D5, and then checks whether the detected key in step D3 is 5TORE or not in step D7.
After passing through the steps, the process advances to steps D8 and D9. In addition, 5T
If it is not the ORE key, proceed to the appropriate step where it is subsequently determined what kind of key it is.

In step D8 above, registers R'ml to R'm5 (
m:1.2.3,]・-), the register corresponding to the contents of the above number register, in this case R'6 corresponding to rJ
1 to R/65 registers are selected, and such R'61 to R'
The contents of registers R5 to R9 are sequentially transferred and stored in register 65 (FIG. 6, 1).

Here, the contents of the R5 to R9 registers are cleared after the transfer. D? In this step, the number register is cleared.

The operating program then cycles through steps M2-M6.

(■) Next, when calling the cooking program and executing the cooking (referred to as RECIPE cooking), the key operations are as follows.

First, when the RECIPEt key is operated, the operation program exits the cycle of steps M2 to M6 at step M5 and enters the RECIPE routine (FIG. 5f).

In the RECIPE routine, in step E1, R
CP-y lag is set n1 continuation< E2 and E6 steps are similar to D2 and M2 steps respectively, and the next E4 step checks the presence or absence of the detection key in E3 step, and now there is none. The operation program then returns to step E2 and cycles through steps E2 to E4.

Then, when the key number B is operated, the operation program exits this cycle from step E4 and proceeds to step E5.

In this step, it is checked whether the key detected in the E5 step is a number, and in this case it is a number, so in the E6 step, the key is stored in the number register in the storage area (4).
6" is set.

The operating program then cycles through steps E2-E4.

Next, when the 5TART key is operated, the operating program completes this cycle, goes through step E5, and then goes through step E7, where it is checked whether the detected key at step E6 is START, and then Es. This leads to step E9. Incidentally, if it is not the 5TART key, the process proceeds to an appropriate step where it is subsequently checked what kind of key it is.

In step E8, the R'61 to R'65 registers corresponding to the above numbers are selected from the R/m1 to R'm5 registers (rrz 1% 2.3,...), and the R' The contents of registers 61 to R6'5 are sequentially R1 to R5,
It is also stored in the R5 and R6 registers.

The contents of registers R'61 to R'65 are held here. E9 step is D? Same as step.

After that, the operating program enters the 5TART routine,
Steps 07 to C14 are cycled through steps C1, C5, and C6, and the first stage is executed. Then, when the first stage is completed, the operating program is CI 6'
, Ci7', C2o.

07 after C22, C23, C1, C5, C6 steps
The second stage is executed by cycling through steps C14.

When the second stage is finished, the sixth stage is executed in the same way, and when it is finished, that is, the RECI
When the PEBq process is completed, the operating program passes through step C24 and cycles through steps M2 to M6.

(V) Now, in the above item
3 /7 + l Kusuzu Arakisu
For example, when 6 minutes and 25 seconds have passed out of the 5 minutes of heating time for the first stage, check the cooking progress while executing step 1. The steps are cycled.The contents of each register at this time are as shown in FIG. 7a.

Then, when I opened the door (3) and checked the cooking status, I found that the rest of the first stage had a heating time of 6 minutes and a microwave output of 20 minutes.
% (1st/stage), if it is determined that the cooking situation will be better, it is sufficient to press the keys 1111 m i 19ookIQ times at this point.

First, when you operate the TIME key, the operating program is C.
The cycle of steps 7 to C9 and C14 is exited from step C14, and the process proceeds to the appropriate step via step C15. In the case of 1. If the detection key in step C8 is at TIME, the operating program then enters the TIME routine and returns to A.
1 to A6 steps are cycled.

So, numbers! If you operate the l and Olo keys quickly,
The operation program is sequential A4. After going through step A5, the contents of part a of the R1 register currently being targeted are “155J.
From [OoJ.

Next, when you operate the C00K key, the operating program will be A.
After 6 steps, the C00K routine is entered, and B1 to B6
Cycle through steps.

Then, when the number 2 and O keys are operated in sequence, the operating program sequentially passes through steps B4 and B5, and the contents of the b part of the R1 register, which is currently targeted, changes from "30" to "2".
0".

Here, the first/stage cooking conditions are set in the R1 register.

Thereafter, when the 5TART key is operated, the operation program enters the 5TART routine via step B6 and other appropriate steps, and then proceeds to step C4 via steps C1 to C3. In this step, the contents of all parts a and b with small numbers in registers R5 to R9 are transferred (
Figure 7 0).

In particular, if the microwave output is not changed (only the heating time is changed), the operating program does not pass through the C4 block, ie, the current contents of the R4 register are not transferred to the R5 register but are retained.

Thereafter, the production program passes through steps C5 and C6 and cycles through steps C7 to C14, and when the 11th stage is executed, and the heating time of this stage has passed for 6 minutes, the above cycle is exited and C16/, Cf7', C20~C2
Go through 3 steps (Figure 7C).

Subsequently, the operating program cycles through steps C1, C2, C5, and C6, and then steps 07 to C14, and the second stage is executed.

Even during such execution, for example, when 8 minutes have elapsed, the cooking progress status should be checked (if the STOP key is operated, the operation program cycles through steps 07 to C9 and C14).

Then, when I opened the door (3 loaves and checked the cooking status),
If it is determined that the cooking situation will be better by changing the microwave output to 8o% for the rest of the stage (leaving no change for the remaining 19 hours and 2 minutes of heating) (21st stage), at this point, It's easy to operate.

First, when you operate the key to 000, the operation program 1d
The cycle of steps c7 to C9 and C14 is exited from step C14 and proceeds to the appropriate step via step C15. In this case, if the detection key at step C8 is C00KK, the operating program will then go to the C00K routine, and B1
- Cycle through B6 steps.

When the number 8 and O keys are operated in sequence, the operating program sequentially passes through steps B4 and B5, and the contents of the b section of the R1 register, which is currently being targeted, changes from "50" to "2".
0".

Here, the cooking conditions for the 2' stage are set in the R1 register.

After that, when you operate the 5TART key, the operating program A
enters the 5TART routine through step B6 and other appropriate steps, and then through steps C1 to C6 to step C4. In this step, registers with small numbers in registers R5 to R9 are all cleared, in this case the at b parts of register R7, and the a and b parts of register R4.
The contents of the section are transferred (Fig. 7d).

After that, the operating program passes through steps C5 and C6.
7 to C14 steps are cycled, the second/stage is executed, and when the heating time of such stage is 2 minutes,
Exiting the above circulation, C16/, C17/, C20 to C23
(Fig. 7e).

Subsequently, the operating program cycles through steps CI, C2, C5, and C6, and steps C7 to C14, and the third stage is executed.

When this stage ends, the operating program again reaches step C21 (FIG. 7f), and then steps C22 and C2.
Steps M2 to M11 are cycled through four steps.

Here, the cooking program consisting of the 1st to 3rd stages in the above item (2) is the 1st stage with an output of 60 chimes and a time of 3 minutes 25 seconds, the 11th stage with an output of 20 ki and a time of 6 minutes, and an output of 50 chimes.
%, 2nd stage for 8 minutes, output 80%, 2nd stage for 2 minutes, output 0%, 6th stage for 6 minutes, and thus the modified cooking program. According to this method, the food will be best finished.

[■] If cooking using such a modified cooking program is to be repeated from now on, the modified cooking program must be stored in a predetermined area as in the above item 1. In this case, if the modified cooking program is specified by cooking number 6, the key operation is p1.When such a key operation is performed, the memory area (4 R'61 to The contents of the R5-R9 registers, that is, the contents of the first, first', second, second, and sixth stages of the modified cooking program, are sequentially transferred to the R'65 register (FIG. 7g).

In particular, when a corrective operation is performed during cooking, the corrected cooking program is stored in a predetermined storage area, so that cooking using the corrected cooking program can be repeated with simple operations. The operation and the operation thereof are the same as in the above section (2).

Incidentally, in the above embodiment, only the explanation of performing microwave heating for a desired heating time at a desired microwave output is given in detail. Of course, it is also possible to perform microwave heating until the heating time is reached, and in this case, the desired heating temperature is stored in place a of the desired register in place of the heating time based on the key operation.

Furthermore, in the above embodiment, each cooking program has R'm1.
~． R'm5 (rn:l, 2, ro, -) It only supports 5 registers, and therefore can only be configured with a maximum of 5 stages, but if you increase the number of registers (421), you can create more cooking programs. It can be composed of stages.
