A washing machine drying time control system, method and washing machine

Abstract

The invention relates to a control system and method for the drying time of a washing machine and the washing machine. The system comprises a humidity sensor, a comparator circuit, a control circuit and a heating device, wherein the humidity sensor is used for detecting the humidity in a barrel when the washing machine is in the drying state; the input end of the comparator circuit is connected with the output end of the humidity sensor, and the comparator circuit is used for outputting a level signal according to the humidity in the barrel and the humidity threshold; the input end of the control circuit is connected with the output end of the comparator circuit, the output end of the control circuit is connected with the heating device, and the control circuit is used for controlling theheating device according to the level signal output by the comparator circuit. According to the technical scheme, the drying degree of clothes is judged according to the humidity conditions, detectedby the humidity sensor, in the barrel, the humidity in the barrel is monitored in real time, and it is achieved that the drying time is controllable.

Description

technical field [0001] The invention belongs to the field of washing machine control, and in particular relates to a washing machine drying time control system and method and a washing machine. Background technique [0002] With the continuous improvement of people's living standards, washing machines have gradually entered the families of ordinary people and spread to thousands of households. Driven by the continuous update and development of technology, the functions of washing machines are becoming more and more perfect, and the drying function of washing machines is one of them. [0003] At present, there are three main types of washing machine drying technology: steam type, condensation type and heat pump type. Among them, steam drying is the most commonly used drying technology. Steam drying is realized by setting a fixed drying time, and the drying function will be stopped when the time is up. In some cases, fixed-time drying may cause the problem of over-drying (to...
