Problems solved by technology

[0008] The period of time after foam has spilled and falls to the floor, causing consumers to slip on the foam, or causing a hazardous condition that shorts out an electrical circuit and results in a fire
[0009] As a result, due to the failure to respond quickly to the occurrence of bubbles, the factors of after-sales service caused by the occurrence of bubbles will increase accordingly, resulting in a decrease in product reliability and customer dissatisfaction

Abstract

The invention relates to a foam detecting method of a washing machine. The foam detecting method of a washing machine in the invention judges whether the foam is generated in the washing process after the unwatering process, rather than by comparing the drainage time and foam drainage time prior to the occurrence of the bubble to determine whether or not. Because of judging the emergence of the foam or not in advance in the course of draining off water, rather than judge in the unwatering process, and carrying out the foam to remove and operate according to judged result, thus the invention can avoid the adverse effect caused by happening in bubble.

Description

technical field [0001] The invention relates to a foam detection method for detecting foam during a washing process of a washing machine. Background technique [0002] figure 1 It is a flow chart of the foam detection and removal method in the execution process of the washing process consisting of water supply, washing, drainage and dehydration processes in the prior art; figure 2 is expressed in time figure 1 The experimental chart of the change of the rotation number of the washing motor during the dehydration process, wherein the X-axis on the chart is expressed in minutes. [0003] refer to figure 1 , the washing process in the prior art is carried out in the order of water supply process S10, washing process S11, draining process S12, dehydration process S13, S16, wherein, in the dehydration process S13, the water level sensor is used to detect the occurrence of foam S14. Generally speaking, when the water level value detected by the water level sensor is lower tha...
