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 having a door lock device of this type has been constructed as shown in FIGS. Hereinafter, the configuration will be described.

[0003] As shown in FIG. 13, a rotary drum 1 has a large number of water passage holes 2 on the entire outer peripheral portion 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 body 8 so as to be openable and closable.
5, the door 9 is held in a closed state.

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, and the like, and the “standard course”, the “speedy” course, the “blanket” course, and the “wool” having different washing times, rinsing times, and dehydration times by the input setting means 48. The washing process such as a course and the drying process can be set, and the set course is sequentially controlled.

Further, as shown in FIG. 14, the lock device 15 locks the claw portion together with the claw insertion plate 16 when the claw portion 34 of the hook of the door 9 is inserted. A lock pin 17, 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 lock pin 17, a pair with the door movable contact 19, and a load of the motor 6, the heater 13 and the like. The door fixed contact 20 connected in series to the door movable contact 19 and a bimetal 21 connected to the locking pin 17 with a slight distance, and a ceramic heater 22 connected to the bimetal 21 and heating it. It is configured. The ceramic heater 22 is controlled by the control means 14 without passing through the door movable contact 19 and the fixed contact 20.

The operation of the above configuration will be described. When the door 9 is opened, laundry is put into the rotating drum 1, the door 9 is closed, and the start / stop switch of the input setting means 48 is pressed to start the operation. The means 14 energizes the ceramic heater 22 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,
Thereby, the claw portion 3 of the hook of the claw insertion plate 16 and the door 9 is formed.
4 is locked. At the same time, the door movable contact 19 connected to the locking pin 17 is pushed upward and connected to the door fixed contact 20. As a result, the load such as the motor 6 and the heater 13 connected in series to the contacts is energized to start a series of washing, rinsing, dehydrating and drying operations. 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. Further, when the washing step and the drying step are set by the input setting means, the laundry is washed, rinsed and dehydrated. Then, in the drying step, hot air is supplied from the hot air supply means 28 of FIG. The laundry is dried while grasping the temperature inside the rotating drum 1 detected by 52.

When all of the preset washing and drying steps are completed, the control means 14
2 and the bimetal 21 is naturally cooled.
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, lock pin 17
Is moved back downward, and the door movable contact 19 and the door fixed contact 20 are opened. Thus, the motor 6 and the heater 13 connected in series to this contact
And so on. At this point, the door 9 is unlocked and the laundry can be taken out.

[0009]

In such a laundry machine, before executing a series of steps of washing, rinsing, spin-drying and drying, the control means 14 controls the power supply to the ceramic heater 22 uniquely. If the power supply by the power switch is cut off (power off) during the drying process to shut off the door and release the door lock state, the power supply is turned on again by the power switch (power on) without delay. However, there is a problem that the door lock state is uniquely released despite the high temperature inside the rotary drum 1.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to release a door lock state according to the temperature in the rotating drum 1 when power supply by a power switch is started.
