First, it is determined whether or not automatic operation is being performed (step S1). When it is determined that the automatic operation is not performed, the process returns to the main routine of the operation control. On the other hand, when it is determined that the automatic operation is being performed, it is determined whether or not the extension key 204 is turned on (step S2).

When it is determined in step S2 that the extension key 204 is turned on, the counting of the operating time of the process being executed is stopped (step S3). And
It is determined whether the extension key 204 is continuously turned on (step S4).

When it is determined in step S4 that the extension key 204 is not continuously turned on, the count value of the operating time of the process being executed is incremented by 1 second (step S5), and the process returns to the may routine. To do.

On the other hand, when it is determined in step S4 that the extension key 204 is continuously turned on, the count value of the operating time of the process being executed is incremented by 1 minute (step S6), and the count is increased. Determine whether the value has reached the upper limit of the operating time of the process being executed (step
S7).

When it is determined in step S7 that the count value has not reached the upper limit of the operating time of the process being executed, the routine returns to the May routine, while in step S7 the operation of the process whose count value is being executed is executed. If it is determined that the upper limit value of the time has been reached, the process waits until the extension key 204 is turned off (step S8), and the process to be executed is shifted to the process immediately before the process being executed ( Step S9),
Return to May Routine.

Further, in the step S2, the extension key 20
If it is determined that 4 is not turned on, the speed key 20
It is determined whether or not 5 is turned on (step S10).
If it is determined in step S10 that the shortcut key 205 is turned on, the counting of the operating time of the process being executed is stopped (step S11). And the short key 20
It is determined whether or not 5 is continuously turned on (step S12).

When it is determined in step S12 that the shortcut key 205 is not continuously turned on, the count value of the operating time of the process being executed is decreased by 1 second (step S13), and the process returns to the may routine. ..

On the other hand, the abbreviated key 205 in step S12
When it is determined that is continuously turned on, the count value of the operating time of the process being executed is counted down by 1 minute (step S14), and it is determined whether or not the count value reaches 0. (Step S15).

If it is determined in step S15 that the count value has not reached 0, the routine returns to the May routine, while if it is determined in step S15 that the count value has reached 0, the shortening key 205 is pressed. After waiting for the process to be turned off (step S16), the process to be executed is transferred to the process immediately after the process being executed (step S17), and the process returns to the may routine.

Further, in the step S10, the abbreviated key
If it is determined that 205 is not turned on, the operating time is counted (step S18), and the process returns to the may routine.

In the control as described above, if the extension key 204 is turned on during operation and the extension key 204 is turned on intermittently, the count value of the operating time is set to 1 for each operation.
When the extension key 204 is continuously turned on for one second, the count value of the operating time is set to 1 during the operation.
Counting up by each minute, the operating time of the process being executed is extended. When the count value of the driving time reaches the upper limit of the setting of the driving time by operating the extension key 204, the process to be executed is shifted to the process immediately before the process being executed. On the other hand, when the speed-up key 205 is turned on during driving, if the speed-up key 205 is turned on intermittently, the count value of the operating time is decreased by 1 second for each operation, and the speed-up key 205 is continuously turned on. When turned on, the count value of the operating time is counted down by 1 minute during the operation, and the operating time of the process being executed is shortened. When the count value of the operating time becomes 0 by the operation of the shortening key 205, the process to be executed is shifted to the process immediately after the process being executed.

In the washing machine of the present invention, the above-mentioned control is performed. Therefore, when the operating time of each process is changed or the process to be executed is changed during the operation, the change can be made while continuing the operation. ..
