Abstract

The damper module of rolling drum washing machine consists of the following part: cylinder with one end connected to washing tub to complete washing operation; buffering spacer installed to the other end of the cylinder; piston with one end contacted to the spacer and capable of friction moving and the other end connected to the outer casing; and eccentricity sensor set between the cylinder and the piston to sense the eccentricity of the washed matter according to the relative motion of cylinder to the piston. The present invention can sense the abnormal vibration of the washing tub so as to regulate the work of the washing machine and reduce vibration and noise.

Description

technical field [0001] The invention relates to the field of washing machines. Background technique [0002] Generally speaking, detergent, washing water, and laundry are put into a drum washing machine installed horizontally, and the laundry is washed by the friction between the drum rotated by the driving force of the motor and the laundry. Almost no damage, no entanglement, and good washing effect. [0003] figure 1 is a side sectional view of an existing drum washing machine; figure 2 It is a sectional view of an existing drum washing machine damper assembly. [0004] Such as figure 1 As shown, the drum washing machine in the prior art includes: a washing tub 4 arranged inside the casing 2 and loaded with washing water; a drum rotatably arranged inside the washing tub 4 and filled with washing water and laundry 6; set at a certain interval on the inner wall of the drum 6, when the drum 6 rotates, the lifting member 8 that lifts the laundry; is connected to the drum...
