DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a laundry machine having a mechanism for locking a door for opening and closing an opening of a machine body.

[0002]

2. Description of the Related Art Conventionally, a laundry machine provided with a door lock device of this kind has been configured as shown in FIGS. Hereinafter, the configuration will be described.

[0003] As shown in FIG. 12, a rotary drum 1 has a large number of water passage holes 2 provided on the entire outer peripheral portion thereof, and is rotatably disposed in an outer tank 3. A rotating shaft 4 is provided at the center of rotation of the rotating drum 1.
Is fixed, and a drum pulley 5 is fixed to the other end of the rotating shaft 4. The motor 6 is connected to the drum pulley 5 by a belt 7 and drives the rotary drum 1 to rotate. A door 9 is provided at the opening of the device main body 8 so as to be openable and closable, and the door 9 is held in a closed state by a lock device (not shown).

The outer tub 3 is suspended by a spring body 10 from the main body 8 of the apparatus, and is supported by a vibration isolator damper 11 so that vibration during dehydration is not transmitted to the main body 8 of the apparatus. A weight 12 is provided. Heater 13
Is for heating the washing water in the outer tub 3. The control means 14 controls the operation of the motor 6, the heater 13, the hot air supply means (not shown) and the like, and the "standard course" having different washing times, rinsing times, and dehydration times depending on the input setting means (not shown). A washing process such as a "speedy" course, a "blanket" course, a "wool" course, and a drying process can be set, and the set courses are sequentially controlled.

A lock device 15 for holding the door 9 closed
Is configured as shown in FIG. 13. When a hook claw (not shown) of the hook of the door 9 is inserted, the claw insertion plate 16 moves to the right, and the claw is moved together with the claw insertion plate 16. A locking pin 17 for locking, a spring 18 for pushing the claw insertion plate 16 to the left when the door is opened, a door movable contact 19 connected to the locking pin 17, and a pair with the door movable contact 19, A door fixed contact 20 connected in series to a load such as the heater 13, and a bimetal 21 connected to the locking pin 17 with a slight distance from the door movable contact 19.
And a ceramic heater 22 for connecting to and heating the bimetal 21. Note that the ceramic heater 22 is controlled by the control means 14 so that the door movable contact 19,
It is controlled without passing through the fixed contact 20.

The operation of the above construction will be described. When the door 9 is opened, laundry is put into the rotating drum 1, the door 9 is closed, and a start / pause switch (not shown) is pressed to start the operation. Means 14 is ceramic heater 2
2 to heat the bimetal 21. After a lapse of several minutes, the heated bimetal 21 pushes the connected locking pin 17 upward due to its temperature displacement characteristic, whereby the claw insertion plate 16 and the claw portion of the hook of the door 9 are locked.

At the same time, the door movable contact 19 connected to the locking pin 17 is pushed upward, and the door fixed contact 20
Connect to As a result, a load such as the motor 6 and the heater 13 connected in series to the contacts is energized, and a series of
Rinsing / dehydration / drying operation is started. During operation, since the ceramic heater 22 is always energized, the bimetal 21 remains heated. Therefore, the door 9 is kept in the locked state.

In the washing process, the rotating drum 1 is driven to rotate at a low speed by the motor 6, and the laundry in the rotating drum 1 is lifted and dropped on the water surface. Thus "washing"
Progresses. The same operation as “washing” is performed in “rinsing”. In “dehydration”, the rotating drum 1 is driven to rotate at high speed, and the laundry is centrifugally dehydrated. Also, when the washing step and the drying step are set by the input setting means, the laundry is washed, rinsed and dehydrated, and then the hot air supply means supplies hot air to the rotating drum 1 to dry the laundry in the rotating drum 1. .

When all of the preset washing and drying steps are completed, the control means 14 cuts off the power supply to the ceramic heater 22 and the bimetal 21 is cooled naturally. After a lapse of several minutes, the cooled bimetal 21 pushes the connected locking pin 17 downward due to its temperature displacement characteristic, whereby the locking of the claw insertion plate 16 and the claw portion of the hook of the door 9 are released.

At the same time, the door movable contact 19 connected to the locking pin 17 is pushed back downward, and the door movable contact 19
And the door fixing contact 20 is opened. As a result, the power supply to the load such as the motor 6 and the heater 13 connected in series to the contact is cut off. At this point, the door 9 is unlocked and the laundry can be taken out.

[0011]

Such a laundry machine generally has a large frontage of the door 9 and can be easily entered by a small child, and the rotary drum 1
The door 9 cannot be opened from inside. Therefore, from the viewpoint of safety, it is desirable to keep the door 9 locked so that the door 9 cannot be opened when the device is not used in a home with small children.

However, in the conventional configuration, in order to keep the lock device 15 in the locked state, the ceramic heater 22 for heating the bimetal 21 must be continuously energized, which causes another problem in safety. Occurs, and
If the power switch is turned off and the supply of power is cut off, the bimetal 21 is naturally cooled, and the lock is easily released.

The present invention solves the above-mentioned conventional problems, in which the door is locked by a specific switch operation of the user, and the locked state is maintained even if the power switch is turned off to cut off the power supply. It is another object of the present invention to prevent this state (hereinafter referred to as a manual lock state) from being easily released.

[0014]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention detects that a door that opens and closes an opening of a rotary drum is opened and closed by door open / close detection means and locks the door in a closed state by a solenoid. Then, the locked state is held by the holding means, and whether the door is in the locked state or the unlocked state is detected by the locked state detecting means. The control means automatically operates a series of washing, rinsing, dehydrating, and drying operations, and by simultaneously pressing one or a plurality of specific switches for a predetermined period of time, drives the solenoid to lock and hold the door, and thereafter, inputs the information. The configuration is such that the reception of all setting means is prohibited.

Thus, even if the door is locked and the power switch is turned off to shut off the power supply, the locked state is maintained and the manual lock state cannot be easily released.

And a door lock display lamp 50h for displaying the locked state of the door 9.

The operation of the control means 45 in the above configuration will be described with reference to the flowchart of FIG. When the user intentionally locks the door 9 of the laundry device manually, the door 9 is closed and the power switch 5 of the laundry device is closed.
8 is turned on, and the input setting means 49 is operated. The flowchart in FIG. 7 is the one at that time. First, in step 60, it is determined whether or not the manual lock state is already set. If not, the process proceeds to step 61. Perform the corresponding processing.
For example, when the course switch 49b is pressed, the course is switched, and the times of washing, rinsing, spin-drying, and drying and the operation contents are changed accordingly. If the manual lock state is set in step 60, the processing of step 61 and subsequent steps is not performed.

Next, the operation for setting the manual lock state will be described from step 62 onward. In step 62, it is determined whether the dehydration switch 49f is on, and in step 63, it is determined whether the drying switch 49g is on. If it is off, the process returns to step 61. If both are on, the process proceeds to step 64, and it is determined whether a predetermined time (3 seconds) has elapsed. If not, the process returns to step 62. That is, steps 62, 63, 6
It is determined whether the dehydration switch 49f and the drying switch 49g are continuously on for a predetermined time (3 seconds) up to 4, and if it is on, the process proceeds to step 65.

Step 66 and subsequent steps are for explaining the operation of bringing the door into a manual lock state. In step 65, it is determined whether or not the door contact point 40 is closed. Since the process cannot be performed, the process returns to step 62. If the door contact 40 is closed, the routine proceeds to step 66, where the solenoid 39 is turned on (driven).

Next, at step 67, the microswitch 4
If 3 is on (unlocked), step 6
At 8, the operation plate 41 and the microswitch 43 connected to the solenoid 39 continue to be turned on for a sufficient operation (1 second), and steps 67 and 68 are repeated. If the micro switch 43 is not turned off even after the lapse of a predetermined time (1 second), the solenoid 39 is turned off in step 69, the failure of the lock device 36 is determined, and an abnormality is displayed on the remaining time display lamp 50g.

Returning to step 67, the microswitch 4
If the door 3 is turned off, it is determined that the door 9 is locked, the solenoid 39 is turned off in step 70, the manual lock state is set in step 71, and the user is informed that the manual lock state is set in step 72. A special display of “Loc” is displayed on the remaining time display lamp 50 g for the purpose of notification, and the process returns to step 60. In step 60, since the state is in the manual lock state, the reception processing of each switch after step 61 is not performed. In this state, even if the power switch 58 is turned off and the power supply is cut off, the lock of the door 9 is mechanically held and the lock state is maintained.

In the above description, steps 62 and 6
In 3, it is determined that two specific switches are on at the same time, but the number of switches may be one or three.

In step 72, the special display of "Loc" is displayed on the remaining time display lamp 50g, but the special display is not always required.

(Embodiment 2) Control means 45 in FIG.
Is configured such that when power is supplied by the power switch 58, the solenoid 39 is driven and the door 9 is unlocked and held. Other configurations are the same as those in the first embodiment.

The operation of the control means 45 in FIG. 1 will be described with reference to the flowchart in FIG. FIG. 8 illustrates the operation of the first embodiment when the door 9 is manually locked and the power switch 58 is turned off, or when the power switch 58 is turned off during the operation of the laundry equipment (the door is locked). This is for releasing the locked state.

First, after the power switch 58 is turned on, if each switch is pressed in step 73, the processing corresponding thereto is performed. For example, when the course switch 49b is pressed, the course is switched, and the times of washing, rinsing, spin-drying, and drying and the operation contents are changed accordingly. Next, in step 74, it is determined whether the door contact 40 is closed. If it is determined that the door 9 is open, the process returns to step 73 since the door 9 is open, and the normal switch reception processing is performed. If the door contact 40 is closed, the process proceeds to step 75, where
If the micro switch 43 is on (unlocked), the process returns to step 73 as in step 74. If the microswitch 43 is in the off state (locked state), the process proceeds to step 76.

After step 76, the door is unlocked. At step 76, the solenoid 39 is turned on (driven). Next, at step 77, the microswitch 43
Is in the OFF state (locked state), the operation plate 41 and the microswitch connected to the solenoid are continuously turned on (1 second) in step 78 for a sufficient operation (step 7).
7. Repeat steps 7 and 78.

The micro switch 43 is operated for a predetermined time (1 second)
If it is not turned on even after the lapse of time, the solenoid 39 is turned off in step 79, and it is determined that the lock device 36 has failed, and an abnormality is displayed on the remaining time display lamp 50g. Step 77
When the micro switch 43 is turned on and the door 9 is determined to be in the unlocked state, the solenoid 39 is turned off in step 80, and the process returns to step 73. The locked state of the door 9 can be automatically released when the power switch 58 is turned on by the operation after step 76.

(Embodiment 3) Control means 45 in FIG.
By pressing one or a plurality of specific switches continuously for a predetermined period of time, the solenoid 39 is driven to lock and hold the door 9, and thereafter, the input setting other than the switch operation for unlocking the door 9 is performed. The reception of the means 49 is configured to be prohibited. Other configurations are the same as those in the first embodiment.

The operation of the control means 45 in FIG. 1 will be described with reference to the flowchart in FIG. Example 1 above
Similarly, when the user intentionally puts the laundry device door 9 in the manual lock state, the user closes the door 9 and turns on the power switch 58 of the laundry device to operate the input setting means 49. The flowchart in FIG. 9 is that at that time.

First, at step 81, it is determined whether or not the manual lock state has been set. If the manual lock state has been set, the routine proceeds to step 82, where the operation waits for the manual lock state to be released, and the processing after step 83 is performed. Absent. At this time, if the manual lock state is released by the release operation, the process proceeds to step 83 and subsequent steps. Returning to step 81, if the manual lock state has not been set, the process proceeds to step 83, and if each switch has been pressed, the processing corresponding thereto is performed. For example, when the course switch 49b is pressed, the course is changed, and the washing, rinsing, dehydrating,
Drying time and operation details are also changed.

Next, the operation of setting the manual lock state will be described after step 84. In step 84, it is determined whether the dehydration switch 49f is on, and in step 85, it is determined whether the drying switch 49g is on. If it is off, the process returns to step 83. If both are on, the process proceeds to step 86, where it is determined whether a predetermined time (3 seconds) has elapsed. If not, the process returns to step 84. That is, steps 84, 85, 8
It is determined whether the dehydration switch 49f and the drying switch 49g are continuously on for a predetermined time (3 seconds) up to 6, and if it is on, the process proceeds to step 87.

Step 87 and subsequent steps are for explaining the setting operation of the manual lock state. In step 87, it is determined whether or not the door contact 40 is closed, and if it is open, the door 9 is locked. Since the process cannot be performed, the process returns to step 84. If the door contact 40 is closed, the process proceeds to step 88, and the solenoid 39 is turned on (driven). Next, if the micro switch 43 is turned on (unlocked state) in step 89, the operation plate 41 and the micro switch 43 connected to the solenoid 39 continue to be turned on for a sufficient time (1 second) in step 90, Steps 89 and 90 are repeated.

The micro switch 43 is operated for a predetermined time (1 second)
If the switch is not turned off even after the lapse of time, the solenoid 39 is turned off in step 91, and it is determined that the lock device 36 has failed, and an abnormality is displayed on the remaining time display lamp 50g. Step 89
When the micro switch 43 is turned off and the door 9 is determined to be in the locked state, the solenoid 39 is turned off in step 92, the manual lock state is set in step 93, and the manual lock state is set in step 94. Is displayed on the remaining time display lamp 50g to inform the user of the
oc ".

Next, in step 95, the manually locked information is written and stored in the nonvolatile memory (storage means) 57, and the process returns to step 81. In step 81, since the manual lock state has already been set, the process proceeds to step 82 without performing the reception processing of each switch after step 83. In this state, even if the power switch 58 is turned off and the power supply is cut off, the lock of the door 9 is mechanically held and the lock state is maintained.

From the above flowchart, the difference from the first embodiment is that, in the third embodiment, even if the manual lock state is once set, the release switch operation for releasing this state is permitted.

In the above description, steps 84, 8
In 5, it is determined that two specific switches are on at the same time, but the number of switches may be one or three.

In step 94, "Loc" is specially displayed on the remaining time display lamp 50g. However, it is not always necessary to perform special display. Similarly, in step 95, the information on the manually locked state is stored in the nonvolatile memory (storage means) 57, but it is not always necessary to store the information.

(Embodiment 4) Control means 45 in FIG.
By pressing one or a plurality of specific switches simultaneously for a predetermined period of time, the solenoid 39 is driven to keep the door 9 in the unlocked state, and thereafter, the input setting means 4
It is configured to allow all nine receptions. Other configurations are the same as those in the first embodiment.

The operation of the control means 45 in FIG.
This will be described with reference to the flowchart of FIG. FIG. 10 illustrates a release operation when the operation of the third embodiment is performed and the door 9 is manually locked.

First, in step 96, it is determined whether or not the manual lock state has been set. If not, the process proceeds to a normal process (for example, the process after step 83 in the third embodiment). If the manual lock state has been set, the state becomes a state of waiting for a release operation after step 97. Step 97
In step 98, it is determined whether the dehydration switch 49f is on. In step 98, it is determined whether the drying switch 49g is on.
Return to 7.

If both are on, the process proceeds to step 99, where it is determined whether a predetermined time (3 seconds) has elapsed. If not, the process returns to step 97. That is, it is determined in steps 97, 98, and 99 whether the dehydration switch 49f and the drying switch 49g are on continuously for a predetermined time (3 seconds), and if it is on, the process proceeds to step 100.

Step 100 and subsequent steps are for explaining the operation of releasing the manual lock state. In step 100, it is determined whether or not the door contact 40 is closed. If the door contact 40 is open, the door is unlocked. Since it is not possible, the process returns to step 97. Normally, when the door 9 is in the locked state, the door contact 40 is always closed. Therefore, the process shifts to step 101 to turn on (drive) the solenoid 39. Next, if the micro switch 43 is in the OFF state (locked state) in step 102, the operation plate 41 and the micro switch 43 connected to the solenoid 39 are kept turned on (1 second) for sufficient operation (1 second) in step 103. 102,
Repeat step 103.

The micro switch 43 is operated for a predetermined time (1 second)
If it is not turned on even after the lapse of time, the solenoid 39 is turned off in step 104, the failure of the lock device 36 is determined, and an abnormality is displayed on the remaining time display lamp 50g. Step 1
02, if the micro switch 43 is turned on, it is determined that the door 9 is in the unlocked state.

First, after the power switch 58 is turned on, information is read from the nonvolatile memory (storage means) 56 in step 109. At step 110, it is determined from this information whether the manual lock state has been set. If it has been set, the process proceeds to step 111, where the operation waits for the manual lock state release operation as shown in step 97 and subsequent steps of the fourth embodiment, and the processing in step 112 and subsequent steps is not performed.

At this time, if the manual lock state is released by the release operation, the process proceeds to step 112 and subsequent steps.
If the manual lock state is not set, step 11
Then, when each switch is pressed, the processing corresponding to the switch is performed. For example, when the course switch 49b is pressed, the course is switched, and the times of washing, rinsing, spin-drying, and drying and the operation contents are changed accordingly.

Next, the processing after step 114 is processing for releasing the locked state of the door 9 when the power switch 58 is turned off during the operation of the laundry equipment (the door is locked). In step 113, door contact 4
If it is determined whether 0 is closed and if it is open,
Since the door 9 is open, the process returns to step 112 to perform normal switch reception processing. If the door contact 40 is closed, the process proceeds to step 114, where the microswitch 43
Is ON (unlocked), step 113
Return to step 112 in the same manner as. Micro switch 43
If is in the off state (locked state), the process proceeds to step 115.

After step 115, the door 9 is unlocked. In step 115, the solenoid 39 is turned on (driven). Next, if the micro switch 43 is in the off state (locked state) in step 116, step 1 is executed.
At 17, the operation plate 41 and the microswitch 43 connected to the solenoid 39 continue to be turned on for a sufficient operation (1 second), and steps 116 and 117 are repeated.

The micro switch 43 is operated for a predetermined time (1 second)
If it is not turned on even after the lapse of time, the solenoid 39 is turned off in step 118, it is determined that the lock device 36 has failed, and an abnormality is displayed on the remaining time display lamp 50g. Returning to step 116, if the micro switch 43 is turned on, it is determined that the door 9 has been unlocked, the solenoid 39 is turned off in step 119, and the process returns to step 112. The power switch 5
When the door 8 is turned on, the locked state of the door 9 can be automatically released.

If the door 9 is manually locked and the power switch 58 is turned off and then turned on, it is determined at step 110 from the information in the memory (storage means). Can continue.
