In steps 65 to 66 and 75 to 81, the control means 27 operates the water supply valve 15a and monitors the water level of the water receiving tub 3 with the water level detecting means 23 in the washing process.
Here, it is determined that the water level of the water receiving tank 3 has not reached 100 mm in the water column even after elapse of, for example, 10 minutes from the start of the operation of the water supply valve 15a, and the control unit 27 forgets to open the water tap. In such a case, there is an abnormality in the water supply system, and "U14" is displayed on the remaining time display section 32g of the display means to notify the user of the abnormality and all loads are stopped. For example, if the temperature of the temperature detecting means 34 is 40 ° C. or less, the locked state of the door 8 can be released because there is no possibility of a burn, and the laundry can be taken out immediately. Also, 40
If the temperature is equal to or higher than 0 ° C., the door 8 and the drum 1 may be hot, so that the door 8 cannot be unlocked and the door 8 cannot be opened, thereby preventing burns.

Steps 67 to 69 and 75 to 81
When the water level in the water receiving tank 3 reaches 100 mm in the water column within a minute, the drum 1 is rotated to start the washing process. Water supply is continued after rotation, but it is considered that washing cannot be performed if water supply is stopped for some reason. Even when the water level does not reach 170 mm in the water column, the above steps 75 to 81 are performed.

Steps 69 to 74 are performed when the water level is 17
If 0mm is detected, the water level will be 1
Water supply is agitated to cut off water supply when the distance is less than 50 mm, and is stopped when water is detected to be 170 mm. The abnormality detection of [U14] has been described in the washing process, but the same applies to water supply in the rinsing process.

In the drying process, the control means 27 operates the water supply valve 15 in step 82, and monitors the water level in the water receiving tank 3 with the water level detection means 33. In steps 83 to 85, the drum 1 is rotated by the drum rotating units 18 and 19, and the circulation unit 24 and the heating unit 2
The drying is started by circulating the air heated in step 1. Step 86
If the water level of the water receiving tank 3 has not reached 100 mm in the water column even after elapse of, for example, 20 minutes after the operation of the water supply valve 15 has been started at Steps 94 to 94, the control means 27 determines whether the water supply faucet has been forgotten to be opened. There is an abnormality in the system, and the remaining time display unit 3 of the display means
"U14" is displayed on 2g to notify the user of the abnormality, and all loads are stopped.

When the temperature of the temperature detecting means 34 is 40 ° C.
In the following cases, it is determined that there is no possibility of a burn, the locked state of the door 8 can be released, and the laundry can be taken out. If the temperature is equal to or higher than 40 ° C., the door 8 and the drum 1 may be hot, so that the lock of the door 8 is not released and the door 8 cannot be opened, thereby preventing a burn.

(Embodiment 3) In the configuration of the first embodiment, the operation during dehydration will be described with reference to FIG.

First, at step 95, the first motor 18 is driven to perform cloth loosening for turning the drum 1 over for 8 seconds on and 3 seconds off. At this time, the drum 1 is set to about 53 r / m
It is controlled to be in. Next, in step 96, the rotation speed of the drum 1 is increased from about 53 r / min to about 100 r / m.
The balance is gradually raised to "in", and a balance control is performed so that the laundry is uniformly attached to the inner wall of the drum 1.

Then, in step 97, the state of imbalance of the laundry is determined. This is a determination for suppressing the vibration when the drum 1 rotates at a high speed during dehydration to a predetermined level.
For example, the determination can be made based on the rotation speed fluctuation amount when the drum 1 is rotating at about 100 r / min. As a result of the determination of the unbalance, if it exceeds the predetermined amount, the process goes to step 98, and the process is repeated from step 95, until the process is repeated 10 times.

If the process has been repeated 10 times in step 98,
In steps 99 to 101, it is detected that an abnormal state such as a tangled cloth is present, and "U13" is displayed by the remaining time portion 32g of the display means to notify the user of the abnormal state and to display all the information. Stop loading. Further, in steps 102 to 104, regardless of the temperature in the drum 1 detected by the temperature detecting means 34, the locked state of the door 8 is released by the door locking means 48, and the door lock display 32h is turned off. The user is notified that the locked state of the door 8 has been released. At this time, even if the inside of the door 8 or the drum 1 is hot at the start of dehydration, the temperature falls during the eleventh time from the loosening of the cloth to the determination of the imbalance, so that even if the locked state of the door 8 is released, burns may occur. It is not.

As a result of the unbalance determination in step 97, if the unbalance is equal to or less than the predetermined amount, in steps 105 and 106, the second motor 19 is turned on to rotate the water corresponding to the vibration resonance point of the water receiving tank 3 or the like. Preliminary spin-drying is performed by rotating the drum 1 to a number of rotations equal to or less than the number of rotations (for example, 200 r / min), and the laundry is more firmly attached to the inner wall of the drum 1 than when the unbalance is determined in step 97.

At this time, for example, if the rotation speed of the drum 1 is less than 100 r / min even after elapse of 20 seconds, step 1
07, the rotation of the drum 1 is stopped, and
At 8, the defoaming sequence is performed. This is because when a highly foamed detergent is used, immediately after the end of washing, the drum 1
And the water receiving tank 3 is filled with bubbles.
Even if the motor 19 is driven, it is determined that it is difficult to rotate the drum 1 at a rotational speed equal to or higher than the rotational speed which has been rotated, and the defoaming sequence is performed. In the defoaming sequence, for example, the drum 1 is rocked every 30 seconds, and this is performed for 15 minutes, so that the bubbles filled between the drum 1 and the water receiving tank 3 can be deleted.

In step 109, if the defoaming sequence is the first time, the flow returns to step 95 to start again from the cloth loosening. On the other hand, if the defoaming sequence is performed twice, in steps 110 to 112, it is detected that the detergent is in an abnormal state due to erroneous use, and the remaining time display unit 32g of the display unit 32 displays “U17”. Is displayed to inform the user of the abnormal condition and all loads are stopped.

Further, from step 113 to step 117
If the temperature in the drum 1 detected by the temperature detecting means 34 is 40 ° C. or less and the water level detected by the water level detecting means 33 is equal to or less than the set water level, the locked state of the door 8 is released by the door locking means 48. And the door lock display 3
2h is turned off to notify the user that the locked state of the door 8 has been released. If the temperature in the drum 1 exceeds 40 ° C. or the water level exceeds the set water level, the door lock state is maintained so that when the door 8 is opened, there is no burn or water leakage. Improves safety.

At step 106, the number of rotations of the drum 1 becomes 10
If it is 0 r / min or more, in step 220, the imbalance state of the strongly adhered laundry is determined again.
If it is determined that the amount exceeds the predetermined amount, the process proceeds to step 98. If less than the predetermined amount, step 2
At 21, the second motor 19 is turned on again to start dehydration. At this time, in steps 118 to 120, the pattern is divided into four patterns according to the number of rotations of the drum 1, for example, 20 seconds after the second motor 19 is turned on.

If it is 300 r / min or more, dehydration is continued until 5 minutes have elapsed. 200r / min or more 300
If it is less than r / min, the second motor 19 is turned off to stop the rotation of the drum 1 and go to step 98. 20
If it is not less than r / min and less than 200 r / min, the second motor 19 is turned off, and then the defoaming sequence is performed. If it is the first time, go to step 95; if it is the second time, go to step 110.

If the speed is less than 20 r / min, it is detected that the rotation detecting means 35 is in an abnormal state such as a failure, and the remaining time display section 32g of the display means 32 displays "F1".
By displaying "2", the user is notified of the abnormal state and all loads are stopped. Since there is a possibility that the drum 1 is rotating at a high speed, the door 8 is not unlocked so that the door 8 cannot be opened to enhance safety.
