Special vibration damper for pulsator washing machine

Abstract

The invention provides a special vibration damper for a pulsator washing machine. The special vibration damper comprises a hanging rod, a hanging rod seat is mounted at one end of the hanging rod, a limit portion is arranged at the other end of the hanging rod, a guide sleeve and a spring support are slidably mounted on the hanging rod, the guide sleeve is arranged between the hanging rod seat andthe limit portion, the spring support is arranged between the limit portion and the guide sleeve, a damping spring is arranged between the spring support and the guide sleeve and mounted on the hanging rod in a sleeving manner, damping is achieved by the aid of the damping spring, a sleeve is fixedly mounted on the guide sleeve upwards, an opening is formed in one end of the sleeve, the other endof the sleeve is closed, the spring support and the damping spring are arranged in the sleeve, a damping ring is mounted on the spring support in a sleeving manner, the damping ring and the inner wall of the sleeve rub, the spring support drives the damping ring and the sleeve to rub when sliding to form frictional damping, so that a damping process of the damping spring is more stable, damping effects are better, running noise of the pulsator washing machine is low, and reliability is high.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a vibration damping device dedicated to a pulsator washing machine. Background technique [0002] The bottom of the bucket of the pulsator washing machine is equipped with a pulsator. Driven by the pulsator, the water flow in the bucket forms an alternating right-handed and left-handed eddy current, which drives the fabric to rotate and tumble to clean the clothes. During the working process, due to loads such as washing items, the pulsator washing machine will generate resonance, which increases the noise during work on the one hand, and causes damage to the pulsator washing machine on the other hand. The vibration damping device is used to bear the load of the entire washing machine and absorb vibration. [0003] At present, there are two types of damping devices used in wave-wheel washing machines at home and abroad, one is a pure friction damping damping device for ...

AI Technical Summary

Problems solved by technology

Among them, the vibration damping device combined with friction damping and air damping is composed of a plastic guide sleeve and a rubber piston installed on the boom. The vibration is realized through the friction between the plastic guide sleeve and the boom and the air damping generated when the rubber piston slides. The damping effect of the damping device of this structure is limited, which affects the use effect of the damping device on the washing machine
