When all the preset washing and drying processes are completed, the control device 14 cuts off the energization of the ceramic heater 22, and the bimetal 21 is naturally cooled. After a few minutes, the cooled bimetal 21 pushes back the connected locking pin 17 due to its temperature displacement characteristics, thereby unlocking the claw insertion plate 16 and the claw portion of the hook of the door 9.
[0010]
At the same time, the movable door contact 19 connected to the locking pin 17 is pushed back downward, and the movable door contact 19 and the stationary door contact 20 are opened. As a result, the energization of loads such as the motor 6 and the heater 13 connected in series to this contact is cut off. At this point, the door 9 is unlocked and the laundry can be taken out.
[0011]

[0030]
The operation of the above configuration will be described with reference to the flowchart of FIG. In general, when the user starts the operation of the laundry machine, the door 9 is opened, the laundry is put into the rotating drum 1, the door 9 is closed, the power switch 58 of the laundry machine is turned on, and the input setting means 49 Select and enter your favorite “course”.
[0031]
The flowchart of FIG. 7 is the subsequent flow chart. First, in step 60, the process waits for the start / pause switch 49c to be pressed. When the switch is pressed, the process proceeds to step 61 to determine whether the door contact 40 is closed. If it is determined that the door 9 is open, it is determined that the user has forgotten to close the door 9, and it is determined in step 62 that the door is open abnormally, and an abnormality is displayed on the remaining time display lamp 50g.
[0032]
If the door contact 40 is closed, the process proceeds to step 63 and the solenoid 39 is turned on (driven). Next, if the micro switch 43 is off in step 63, it is determined that the door 9 is locked. In step 64, the solenoid 39 is turned off, and a series of washing, rinsing, dehydration and drying operations are started. If the micro switch 43 is in the ON state, the operation plate 41 connected to the solenoid 39 and the micro switch 43 are kept on for a sufficient time (1 second) in step 65, while steps 64 and 66 are repeated.
[0033]
If the micro switch 43 does not turn off after a predetermined time (1 second), the solenoid 39 is turned off at step 67, and it is determined that the locking device 36 has failed. As with step 62, the remaining time display lamp 50g is displayed. An error is displayed. That is, after step 67, washing, rinsing, dehydration, and drying operations are not performed.
[0034]
As described above, according to the present embodiment, the control means 45 drives the solenoid 39 for a predetermined time by pressing the start / pause switch 49c, and starts automatic operation when the lock state detection means 43 detects the lock. Since it is configured to shift, the door 9 can be reliably locked only by driving the solenoid 39 for a short time (1 to 3 seconds), and after the start / pause switch 49c is pushed, Can be shortened in a short time until the operation is started.
[0035]
In the above description, immediately after the solenoid 39 is turned on in step 63, the locked state of the door 9 is detected in step 64, but after a short delay time (about 0.2 seconds). The locked state of the door 9 may be detected. In step 67, it is not always necessary to display an abnormality, and washing, rinsing, dehydration, and drying operations may be stopped.
[0036]
(Example 2)
The control means 45 in FIG. 1 presses the start / pause switch 49c to drive and stop the solenoid 39 for a predetermined time, and when the micro switch (lock state detection means) 43 does not detect the lock, The display means 50 is configured to display an abnormality. Other configurations are the same as those of the first embodiment.
[0037]
The operation of the above configuration will be described with reference to the flowchart of FIG. FIG. 8 is a flowchart when the user starts the operation of the laundry machine as in the first embodiment. First, in step 68, the process waits for the start / pause switch 49c to be pressed. If it is determined that the door contact 40 is closed and it is determined that the door is open, it is determined that the user has forgotten to close the door, and it is determined in step 70 that the door is open abnormally and is displayed on the remaining time display lamp 50g. I do.
[0038]
If the door contact 40 is closed, the process proceeds to step 71 and the solenoid 39 is turned on (driven). In step 72, the operation plate 41 connected to the solenoid is kept on for a sufficient time (0.2 seconds), and then in step 73, the solenoid is turned off. Next, if the micro switch 43 is off in step 74, it is determined that the door 9 is in a locked state, and a series of washing, rinsing, dehydrating and drying operations are started.
[0039]
If the micro switch 43 is in the ON state, in step 75, the operation of the micro switch is waited for a predetermined time (0.8 seconds), while steps 74 and 75 are repeated. If the micro switch 43 does not turn off after a predetermined time (0.8 seconds), the repeat counter for counting the number of times the solenoid is turned on / off is incremented by 1 in step 76.
[0040]
Further, in step 77, it is determined whether or not the value of the repeat counter has reached a predetermined number (three times). If not, the process returns to step 71 and the procedure up to step 77 is repeated. If the repeat counter reaches the predetermined number of times, it is determined in step 78 that the lock device 36 has failed, and an abnormal display is performed on the remaining time display lamp 50g.
[0041]
As described above, according to the present embodiment, the control means 45 pushes the start / pause switch 49c so that the solenoid 39 is driven for a predetermined time and stopped for a predetermined number of times. When 43 does not detect the lock, the display means 50 is configured to display an abnormality, so that even if the solenoid 39 is controlled so that the door 9 is repeatedly locked, the lock cannot be locked. 1 to 3 seconds), and the user can be surely notified in a short time.
[0042]
(Example 3)
The control means 45 in FIG. 1 locks the microswitch (lock state detection means) 43 even if the solenoid 39 is repeatedly driven and stopped for a predetermined number of times after all automatic operations of washing, rinsing, dehydration and drying are completed. When the release state is not detected, the display unit 50 is configured to display an abnormality. Other configurations are the same as those of the first embodiment.
[0043]
The operation of the above configuration will be described with reference to the flowchart of FIG. FIG. 9 is a flowchart at the end of a series of washing, rinsing, dehydrating, and drying operations. First, washing and rinsing in step 80 are performed until the steps such as washing and rinsing selected in step 81 before the operation is completed. When the dehydration and drying operations are executed and all the processes are completed, the routine proceeds to step 82 where it is determined whether or not the door contact 40 is closed.
[0044]
Normally, the door contact 40 remains closed during the operation, but if it is open, it is determined in step 83 whether the door contact 40 is open for a predetermined time (10 seconds), and the predetermined time continues. If it is open, it is determined that the locking device 36 in which the door contact 40 is incorporated is out of order, and the process proceeds to step 91 to display an abnormality on the remaining time display lamp 50g.
[0045]
Returning to step 82, if the door contact 40 is closed, the routine proceeds to step 84, where the solenoid 39 is turned on (driven). In step 85, the operation plate 41 connected to the solenoid 39 is kept on for a sufficient time (0.2 seconds), and then in step 86, the solenoid 39 is turned off. Next, if the micro switch 43 is in the on state in step 87, it is determined that the door 9 is in the unlocked state, and the process proceeds to the operation end buzzer notification process. If the microswitch 43 is in the OFF state, the operation of the microswitch is waited for a predetermined time (0.8 seconds) in step 88, and steps 87 and 88 are repeated during that time.
[0046]
If the micro switch 43 is not turned on even after a predetermined time (0.8 seconds) has elapsed, a repeat counter for counting the number of times the solenoid 39 is turned on / off is incremented by 1 in step 89. Further, in step 90, it is determined whether or not the value of the repeat counter has reached a predetermined number (three times). If not, the process returns to step 84 and the procedure up to step 90 is repeated. If the repeat counter reaches the predetermined number of times, it is determined in step 91 that the lock device 36 has failed, and an abnormality is displayed on the remaining time display lamp 50g.
[0047]
As described above, according to the present embodiment, the control unit 45 locks the micro switch (lock state detecting unit) 43 even if the solenoid 39 is repeatedly driven and stopped for a predetermined number of times after all automatic operations are completed. When the release state is not detected, the display means 50 is configured to display an abnormality, so that the door 9 can be securely locked only by driving the solenoid 39 for a short time (1 to 3 seconds) after all the operations are completed. The unlocked state can be set, the time until the door 9 can be opened can be shortened in a short time, and the lock cannot be released even if the solenoid 39 is controlled so that the door 9 is repeatedly unlocked. Therefore, it is possible to reliably notify the user of the failure of the locking device in a short time (1 to 3 seconds).
[0048]
In the above description, when an abnormality of the door contact 40 is detected in step 83, the process proceeds to step 91 to display the same abnormality display. However, the abnormality display may be different from the abnormality display of step 91.
[0049]
(Example 4)
The control means 45 in FIG. 1 detects the unlocked state by the micro switch (lock state detecting means) other than the temporary stop by pressing the start / pause switch 49c after the automatic operation of washing, rinsing, dehydration and drying is started. In this case, the solenoid 39 is driven so that the door 9 is locked and held. Other configurations are the same as those of the first embodiment.
[0050]
The operation of the above configuration will be described with reference to the flowchart of FIG. FIG. 10 is a flowchart of a series of washing, rinsing, dehydrating and drying operation operations. First, in step 92, it is determined whether the start / pause switch 49c is pressed and the operation is paused. , A series of washing, rinsing, dehydration and drying operations in step 93 are executed.
[0051]
Next, the routine proceeds to step 94 where it is determined whether or not the door contact 40 is closed. Normally, the door contact 40 remains closed during the operation, but if it is open, it is determined in step 95 whether the door contact 40 is open for a predetermined time (10 seconds), and the predetermined time continues. If it is open, it is determined that the locking device 36 in which the door contact 40 is incorporated is out of order, and the routine proceeds to step 104 where an abnormality is displayed on the remaining time display lamp 50g.
[0052]
Returning to step 94, if the door contact 40 is closed, the process proceeds to step 96. If the microswitch 43 is in the off state, it is determined that the door 9 is in the locked state, and the process returns to step 93 to perform a series of washing and rinsing. Continue dehydration and drying operations. If the power switching means 54 malfunctions due to noise or the like, the solenoid is turned on, and the door lock is released, the process proceeds to a re-door lock process after step 97. In step 97, the solenoid 39 is turned on (driven).
[0053]
Next, in step 98, the operation plate 41 connected to the solenoid is kept on for a time (0.2 seconds) during which the operation plate 41 operates sufficiently, and then in step 99, the solenoid is turned off. Next, if the micro switch 43 is in the OFF state in step 100, it is determined that the door 9 is in the locked state, and the process returns to step 93 to continue a series of washing, rinsing, dehydration and drying operations. If the micro switch 43 is in the ON state, the operation of the micro switch is waited for a predetermined time (0.8 seconds) in step 101, and steps 100 and 101 are repeated during that time.
[0054]
If the micro switch 43 is not turned off even after a predetermined time (0.8 seconds) has elapsed, a repeat counter for counting the number of times the solenoid 39 is turned on and off is incremented by 1 in step 102. Further, in step 103, it is determined whether or not the value of the repeat counter has reached a predetermined number (three times). If not, the process returns to step 97 and the procedure up to step 103 is repeated. If the repeat counter reaches the predetermined number of times, it is determined in step 104 that the lock device 36 has failed, and an abnormality is displayed on the remaining time display lamp 50g.
[0055]
As described above, according to the present embodiment, the control means 45 detects that the micro switch (lock state detection means) detects the unlocked state other than the temporary stop by pressing the start / pause switch 49c after the automatic operation starts. In this case, since the solenoid 39 is driven and the door 9 is locked and held, even if the door 9 is unlocked due to noise or the like during operation, the door 9 is again locked and inadvertently By opening the door 9, washing water can be prevented from splashing and hot air from the hot air supply means can be prevented from being ejected, and the safety of the user can be ensured.
