Control method of washing machine and washing machine

Abstract

The invention belongs to the field of washing machines, and particularly relates to a control method of a washing machine and the washing machine. In the dewatering process before a rinsing procedure, when the washing machine detects that the rotational speed of a washing drum in the dewatering process is reduced to a preset value V1, a spraying procedure is controlled to be started. The control method of the washing machine and the washing machine have the advantages that 1, by detecting the rotational speed of the washing drum, starting of the spraying procedure is controlled according to the rotational speed of the washing drum, spraying is avoided when the rotational speed of the washing drum is near a resonance point, splashing is reduced, and the spraying effect is improved; 2, spraying is conducted in the dewatering process, the cumbersome process of separately setting the spraying procedure is avoided, the dewatering process is fully utilized, and the time is saved; 3, because in the dewatering process, the speed of the washing drum is gradually reduced, the controllability is good, the splash-proof effect is good, and the good spraying effect can be achieved.

Problems solved by technology

[0002] At present, during the rinsing process of the ordinary program of the frequency conversion fully automatic washing machine, it enters the spraying program after performing low-speed, coasting off, and braking; according to the experimental feedback, when the clothes load is eccentric in this control method, the washing machine bucket dehydrates from a static state at a low speed during the spraying process. , it is easy to produce the probability of barrel collision, which affects the automation rate of the whole machine, the migration rate, and the market reputation

[0003] The start-up spray program of the washing machine is controlled by time, and the washing machine executes the corresponding program sequentially according to the set time. However, the rotation speed of the washing tub is affected by many factors, such as the amount of water, the weight of clothes, etc., the same time, different Under normal circumstances, the speed of the washing bucket increases or the speed that the washing bucket can achieve is quite different. If the speed of the washing bucket falls near the resonance point, causing resonance, it will seriously affect the spray effect

[0004] In order to reduce the time for the washing tub to stop after the inertia, the brakes are generally set after the inertia. Setting the brakes will increase the possibility of the washing bucket hitting the bucket and affect the execution of the follow-up procedures; This spraying, because the speed of the washing tub increases slowly when it starts to rotate, the spraying time near the resonance point is longer, which seriously affects the spraying effect

[0005] Therefore, in order to design a program control method for the rinsing and spraying process, it is an urgent problem to be solved to improve the rinsing and spraying process of the variable frequency automatic washing machine, which is prone to barrel collision and affects the automation rate and migration rate of the whole machine.
