Defoaming method of washing machine and washing machine

Abstract

The invention discloses a defoaming method of a washing machine and the washing machine. When the washing machine washes clothes, an ultrasonic generator is started, and ultrasonic waves generated bythe ultrasonic generator are transferred to foam produced during clothes washing through washing water in the washing machine to remove foam by vibration. The drum washing machine is defoamed by the ultrasonic generator, ultrasonic waves generated by the ultrasonic generator remove foam by vibration, meanwhile, the defoaming efficiency is enhanced by cooperation of the ultrasonic generator and a spray washing device, start and stop of the ultrasonic generator and the spray washing device are controlled by monitoring pressure in a drum, operation is simplified, user experience is enhanced, theultrasonic generator can enhance the cleaning degree of clothes during clothes washing, some stubborn stains on clothes can be washed up, the washing capacity of the drum washing machine is enhanced,and the scheme is simple in structure and high in operability.

Description

technical field [0001] The invention belongs to the technical field of laundry devices, and in particular relates to a defoaming method for a washing machine, and also relates to a washing machine for defoaming treatment in the above manner. Background technique [0002] In the drum washing machine in the prior art, when there is too much detergent or a high-foaming detergent is used during the washing process, due to reasons such as stirring and water flow impacting the detergent, the air and the detergent are in continuous contact, and excessive foam is likely to be generated. If it is not removed in time, a large amount of foam will cause the pressure in the cylinder to be too high. The foam filled in the inner and outer cylinders will make the motor rotate hard, resulting in overheating and stalling. It will cause abnormal water intake, foam will overflow the washing machine, affect the performance of the washing machine and user experience, and cause waste of detergent;...

[0002] In the drum washing machine in the prior art, when there is too much detergent or a high-foaming detergent is used during the washing process, due to reasons such as stirring and water flow impacting the detergent, the air and the detergent are in continuous contact, and excessive foam is likely to be generated. If it is not removed in time, a large amount of foam will cause the pressure in the cylinder to be too high. The foam filled in the inner and outer cylinders will make the motor rotate hard, resulting in overheating and stalling. It will cause abnormal water intake, foam will overflow the washing machine, affect the performance of the washing machine and user experience, and cause waste of detergent; if the foam remains in the washing machine, it will also affect the washing effect, for example, after the dehydration is completed, the foam still remains in the front door On the glass or window mat, if the user does not pay attention, it is easy to rub the foam when taking out the washed clothes. The clothes that have been washed will be polluted again, and the foam remaining in the window mat will be damaged if it is not removed in time. It is easy to breed bacteria on the window mat. In order to avoid the above phenomenon, a defoaming step must be carried out. However, the rapid defoaming in the prior art itself is a big problem, and the traditional drum washing machine cannot solve this problem well. The existing The method is to dilute the foam in the washing machine through the drainage and replenishment process, which will prolong the washing time and waste water resources
