Kind Code:

B2

Abstract:

PURPOSE:To suppress noise generation, by setting a special course for setting the quiescence time limit of a motor longer than in the case of a standard course or setting the driving time limit of the motor shorter than in the case of the standard course, and for setting an operation practicing time longer than in the case of the standard course, besides the standard course. CONSTITUTION:On the washing operation of a long course, a motor is forward- operation-driven with the same driving time limit Ta as the driving time limit T1 of a standard course, and after that, the motor is stopped with a quiescence time limit Tb longer than the quiescence time limit T2 of the standard course, and is reverse-operation-driven with the driving time limit Ta, and after that, quiescence with the quiescence time limit Tb is repeated. In this case, the quies cence time limit Tb of the motor is longer than the quiescence time limit T2 of the case of the standard course, and so the attenuating time of the strength of water current is made longer, and in other words, a water current weakening degree is increased. As this result, when an agitating body is reversed from forward operation to reverse operation or from the reverse operation to the forward operation, then the water current is already attenuated, and waving or water splash is suppressed, and noise generation can be suppressed.
