Washing machine controlling method

Abstract

The invention discloses a washing machine controlling method. The dirt degree of drums caused by every time of washing is calculated and superimposed, and when the superimposed value reaches or exceeds a critical value, a washing machine drum cleaning prompting signal is sent out. The dirt degree of the drums caused by every time of washing is calculated or detected, and then the calculation result or the detection result of every time is superimposed. When the superimposed value, namely the total value of the dirt degrees of the drums, reaches or exceeds the preset dirt degree critical valueof the washing machine drums, the washing machine can then send out the cleaning signal, then it is regarded that the dirt degree of the drums reaches the preset cleaning degree, then a user is reminded to conduct cleaning so that the user can timely clean the washing machine drums, thus bacteria are prevented from being bred in the drums, and the cleanliness of the washing machine drums is maintained; by detecting or calculating the dirt degree of the drums of every time of washing, the accuracy of the detection result of the total dirt degree of the drums is improved, and then the cleaning effect of the washing machine drums is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing machine control method for cleaning a washing machine tub. Background technique [0002] The washing machine is a household appliance with water, and its internal environment is very humid. After a period of use, the detergent components in the water, the oily stains in the clothes, and the shedding dandruff, etc. adhere to the inner and outer barrel walls, and then moldy It turns black and breeds bacteria. If it is not cleaned in time, it may cause cross infection and cause various diseases. However, due to the structural problems of the washing machine, it is difficult for users to clean the washing machine by themselves, so the washing machine starts to set its own cleaning function; at the same time, the washing machine is not easy to disassemble, which makes it difficult for users to judge the degree of dirt in the washing tub. For the user's convenie...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned patent document, the dirty condition of the washing bucket is preliminarily judged by the number of washing times and the interval time from the last bucket cleaning, and the dirt information of the laundry bucket is further detected by the sensor, and it is judged whether to clean the bucket according to the dirty information; In the washing machine tub wall dirt detection and reminder method, although there are interval time interpretation and sensor detection for tub cleaning, there is no necessary relationship between the degree of dirtiness of the tub and the interval time, such as washing for a long time and being slightly dirty. soiled laundry and heavily soiled laundry washed for a shorter period of time may cause the same degree of soiling to the wash tub

And the sensor can only detect the degree of dirtiness of the bucket at its setting point, its detection points are limited, and the reference value of the detection results is small
