A control method for detecting foam in a washing bucket and a washing machine

Abstract

The invention provides a control method for detecting foam in a washing tub and a washing machine. Wherein, the use of the control process includes a first conductivity detection device, a second conductivity detection device, a computer-readable storage medium, and a control device. Detect and record the conductivity of the clean water entering the washing tub, the conductivity of the washing water in the washing tub in the washing stage, and the conductivity of the soaking water in the soaking and pre-washing stage; and preset the allowable deviation value of the conductivity in the computer-readable storage medium; , The difference between the conductivity of soaking water and the conductivity of clean water is compared with the allowable deviation value of conductivity, so as to control the laundry program to enter the defoaming stage and the soaking pre-wash stage until the defoaming is completed. Accurately determine whether there is residual foam on the clothes during the washing process through the electrical conductivity, and control the completion of defoaming, so as to avoid secondary pollution to the clothes caused by unclean defoaming, and avoid the existing technical solutions due to inaccurate judgment. Continue to defoaming the problem many times, saving electricity and water resources.

Description

technical field [0001] The invention relates to the technical field of smart household appliances, in particular to a control method for detecting foam in a washing bucket and a washing machine. Background technique [0002] With people's living standards getting higher and higher, washing machines have also become an indispensable household appliance in life, bringing great convenience to daily life. With the development of washing machine technology, the functions of the existing washing machines on the market are becoming more and more abundant. During the washing process, the problem of how to efficiently and cleanly remove the detergent foam attached to the clothes and dissolved in the water has begun to be widely accepted. focus on. The common method of eliminating foam in the current washing machine is to judge whether to enter the defoaming stage according to the eccentric value and power of the motor at a certain speed. It will be difficult to accurately judge whe...

AI Technical Summary

Problems solved by technology

By adopting the detection and control scheme of the present invention, it is possible to accurately judge whether there is foam remaining on the clothes during the washing process, and to control and complete the defoaming, thereby avoiding secondary pollution of the clothes caused by unclean defoaming, and at the same time avoiding the use of The inaccurate judgment of motor eccentricity and power causes the problem that the foam has been removed but continues to enter the defoaming problem many times, saving electricity and water resources
