Title:
METHOD FOR DETECTING AND REMOVING FOAMS FOR USE IN WASHING MACHINES
Document Type and Number:
WIPO Patent Application WO/2018/103698
Kind Code:
A1
Abstract:
A method for detecting and removing foams for use in washing machines, which detects water level pressure information while a rolling drum of a washing machine is speeding up in a dewatering process, and implements a removal procedure on the basis of the water level pressure information. The method solves the problem of detecting and removing residual foams in a washing process of a washing machine, and uses a high-speed rolling drum to mix the foams and water, which increases the air pressure inside of the rolling drum, thus increasing the water level pressure; then, water level pressure information inside of the rolling drum is detected by means of a pressure detection sensor or a water level sensor so as to obtain a residual foam content. The method effectively increases the sensitivity when detecting residual foams in a rolling drum; the state of the residual foams in the rolling drum may be accurately obtained on the basis of the water level pressure information, and a removal procedure may be implemented in a timely manner, ensuring the washing performance of the washer machine.
