Judgment method of start-up washing machine self-cleaning program

Abstract

The invention discloses a method for determining to start a washing machine automatic cleaning program, which comprises the following steps: an initial value of muddy degree is set for the washing machine; afterwards, every time before or after washing, when the water drainage pipe has no water, the detected value of a muddy degree sensor is recorded as the current value of muddy degree; when the difference of the current value of muddy degree and the initial value of muddy degree is more than the preset threshold of starting the automatic cleaning program, the startup of the automatic cleaning program is determined; the user is reminded to start the automatic cleaning program of the machine starts the automatic cleaning program automatically. Compared with the prior art, the device uses the muddy degree sensor that the prior full automatic washing machines are commonly equipped with to obtain the changes of the detected value of the muddy degree sensor, and the changes are considered as the determining conditions for the need of starting the automatic cleaning program. Through the method, no device needs to be added for the washing machine, so that quite accurate determination results can be obtained, and the automatic cleaning program can be started appropriately.

Description

technical field [0001] The invention relates to washing machine technology, in particular to a determination method for starting a self-cleaning program of a washing machine. Background technique [0002] Washing machine is an essential household appliance in the family. General family all uses the fully automatic washing machine with stronger degree of automation at present. [0003] Fully automatic washing machines include pulsator washing machines and drum washing machines. The washing tubs of the above two washing machines are composed of two cylinders, an inner cylinder and an outer cylinder. The inner cylinder is a perforated cylinder, the outer cylinder is a water storage cylinder, the inner cylinder and the outer cylinder are coaxial, and the inner cylinder is rotated by the motor through the shaft. The pulsator washing machine spins and dries the clothes by rotating the inner cylinder; the drum washing machine washes and dries the clothes by rotating the inner cyl...

AI Technical Summary

Problems solved by technology

When the washing machine is in normal use, the condition of the interlayer between the inner and outer drums cannot be observed, so the user has great blindness when to start the self-cleaning program

If the user starts the self-cleaning program too frequently, since the self-cleaning program itself requires electricity and water, but does not produce any benefits, it will cause unnecessary waste of water and electricity resources

Laundry can become soiled if too long between user-activated self-cleaning programs

[0007] Another problem is that since the self-cleaning program itself does not detect the effect of self-cleaning, after the self-cleaning program is completed, if there is still dirt, it may still pollute the clothes
