Damping assembly, washing machine and control method

Abstract

The invention provides a damping assembly, a washing machine and a control method. The damping assembly comprises a fixed base, a safety buckle and an elastic piece, wherein a piece to be damped is connected to the fixed base through the safety buckle and the elastic piece; and the safety buckle can adjust the deformation quantity of the elastic piece. The safety buckle and the elastic piece are arranged between the piece to be damped and the fixed base, the deformation amount of the elastic piece is adjusted through the safety buckle, and strenuous vibration of the piece to be damped is relieved.

Description

technical field [0001] The application belongs to the technical field of washing machines, and in particular relates to a shock absorbing assembly, a washing machine and a control method. Background technique [0002] The washing machine will cause severe vibration and noise in the working state, which is a big problem in the research and development process of the washing machine at present. The main reason is that the clothes in the washing machine are not evenly distributed. Especially washing machines. Because the drum of the drum type washing machine is placed horizontally, and its working principle is that the high-speed rotation of the motor drives the clothes up, so that the clothes are repeatedly beaten in the drum to bring out the stains in the fabric, and finally the stains are taken away by the water flow. This method is difficult to control. Barrel balance, will cause serious barrel vibration. [0003] In the prior art, a design idea of ​​designing an airbag u...

Problems solved by technology

Because the drum of the drum type washing machine is placed horizontally, and its working principle is that the high-speed rotation of the motor drives the clothes up, so that the clothes are repeatedly beaten in the drum to bring out the stains in the fabric, and finally the stains are taken away by the water flow. This method is difficult to control. Barrel balance, will cause serious barrel vibration

[0003] In the prior art, a design idea of ​​designing an airbag under the washing machine to achieve a cushioning effect has been proposed. However, this type of airbag is similar to an automobile airbag and can only slow down the impact from the front. The motor of the drum washing machine rotates horizontally. The vibration in the vertical direction is more obvious due to the acceleration of gravity, but the effect of centrifugal force in other directions cannot be ignored. This solution is difficult to realize

It is also proposed to use the gyroscope sensor to collect the three-dimensional vibration of the washing machine, but only to set the collection threshold, and to reduce the motor speed under the condition that the severe vibration meets the threshold. Washing machine setting parameters contradictory

That is to say, the prior art cannot solve the shock absorption problem of the drum washing machine
