てからモータへ通電していた。BACKGROUND OF THE INVENTION Conventionally, in a control device for this type of washing machine, when the lid is opened during dehydration, the power to the drain valve driving means and the motor is cut off.
When the lid is closed again, power is restarted to the drain valve drive means and the motor, but at that time the drain valve drive means does not wash or wash.
If the motor is not energized after the dewatering mode has been completely switched, there is a risk that a loud noise will be generated. In other words, the drain valve driving means drives a switching mechanism that switches between washing and dewatering, and when the drain valve driving means is de-energized, the switching mechanism is braked, so the drain valve driving means drives the switching mechanism. If the motor was energized without fully releasing the brake, it would generate a loud noise. Therefore, as shown in Figure 6, when the lid is opened and then closed again, the drain valve is opened first (the drain valve driving means is energized), and the time required to completely switch to dewatering is delayed. After that, the motor was energized.

り目立つというものであった。Problems to be Solved by the Invention Recently, however, attention has been focused on making washing machines quieter, and it has become necessary to reduce even the momentary sound when switching, so the structure described above is not sufficient. lost. If the lid was opened during dehydration and the lid was closed again after the motor completely stopped, there would be no problem with the conventional method as shown in Figure 6, but if the lid is opened and the motor stops before the motor stops, When the lid is closed, the drain valve driving means is energized while the motor is rotating, and in this case, a problem has become clear that a loud noise is generated from the clutch part of the switching mechanism. In particular, in order to reduce noise, when a geared motor type was used instead of the conventional plunger type as the drain valve drive means, it took time to switch the mechanism and the mechanism was pulled slowly, which resulted in noise when switching. It was more noticeable.
そこで本発明は、脱水中の蓋の開閉による異音の発生を
抑えた洗濯機の制御装置を提供することを目的としてい
る。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a washing machine control device that suppresses the generation of abnormal noises caused by opening and closing a lid during dehydration.

遅らせることもない。To explain the operation with the above configuration, during dewatering, the motor 6
When the lid 12 is opened and the lid switch 13 is opened, the control means 14 stops energizing the motor 6 and the drain valve driving means 8, and at the same time starts the timer T. Let it start. This time T is
The time from when the energization to the motor 6 and the drain valve driving means 8 is stopped until the rotation actually stops is determined in advance and stored in the control means 14 assuming various conditions. It is. Then, as shown in the timing shown in FIG. 3, when M12 is closed again and the lid switch 13 is closed before the time T has elapsed, the control means 1
4 determines that the rotation of the motor 6 has not yet stopped, and resumes energization to the drain valve driving means 8 after a delay of time t after the lid switch 13 is closed, and then restarts the switching mechanism 7. After waiting for complete switching and delaying the time t2, energization to the motor 6 is resumed, thereby suppressing the generation of noise. Further, as shown in FIG. 4, if the lid 12 is closed after 7 or more hours have elapsed since the lid 12 was opened, it is determined that the motor 60 rotations have stopped,
Since the energization to the drain valve driving means 8 is immediately resumed, and the energization to the motor 6 is resumed after waiting for t2, there is no pointless delay in time.

ができ、同様の効果を得ることができる。The above explanation has been about the control when temporarily stopping the dewatering process by opening and closing the lid 12, but it is also possible to temporarily stop and restart the dewatering process using the pause switch connected to the control means 14. The same thing can be done for control, and the same effect can be obtained.
