The transmitting coil 80 is energized to operate in a resonant state, and generates and transmits a high-frequency alternating current. The receiving coil 70 close to the receiving coil generates current through electromagnetic induction, the ultrasonic transducer 50 is driven to work through the ultrasonic controller 60, the ultrasonic transducer 50 emits high-frequency ultrasonic waves to the inside of the inner drum 20, insoluble or insoluble dirt on the clothes is broken, oil dirt is emulsified, the dirt is separated from fibers of the clothes and is dispersed in a washing solution, and the purpose of strongly cleaning the clothes is achieved. It is understood that the above operation is an operation in which the transmitting coil 80 and the receiving coil 70 use electromagnetic induction. If the transmitting coil 80 and the receiving coil 70 operate in a magnetic resonance manner, the transmitting coil 80 is energized and vibrates at a certain resonance frequency to radiate an electromagnetic field to the surroundings, and the receiving coil 70 also vibrates at the resonance frequency to receive the energy transmitted by the transmitting coil 80 and generate a current, which is supplied to the ultrasonic controller 60, and the operation processes of the ultrasonic controller 60 and the ultrasonic transducer 50 are the same as the above operation processes.

By adopting the above scheme, the ultrasonic transducer 50 is arranged at the rib part 41 of the impeller 40, ultrasonic waves are emitted to remove stains on clothes, the dirt removing capability is strong, the clothes abrasion is reduced, the forward and reverse rotation switching frequency of the impeller 40 is not required to be additionally accelerated or the clothes washing time is not required to be prolonged, and the increase of the electric energy loss of the impeller type washing machine 100 is avoided.
