Shock-absorbing device of washing machine and washing machine

Abstract

The invention provides a shock-absorbing device of a washing machine and the washing machine. The washing machine shock-absorbing device includes a shock-absorbing suspension rod, an upper bracket, ashock-absorbing spring and a sliding-damping supporting base; the end portion of the upper end of the shock-absorbing suspension rod is installed on a box body of the washing machine, the upper bracket is installed on an outer drum of the washing machine, and the shock-absorbing suspension rod sequentially penetrates through the upper bracket, the sliding-damping supporting base and the shock-absorbing spring from top to bottom; the sliding-damping supporting base is provided with a damping-variable structure and used for transmitting eccentric force to generate sliding damping acting on the shock-absorbing suspension rod when the outer drum shakes or swings. According to the shock-absorbing device of the washing machine, when the washing machine starts and runs for dewatering, a sliding damping force is provided through friction between the sliding-damping supporting base and the shock-absorbing suspension rod, the shake and swing of the outer drum are effectively reduced, a good shock-absorbing effect is achieved, and washing machine can keep quiet and stable dewatering start-up and running.

Description

technical field [0001] The invention relates to the technical field of shock absorption for washing machines, in particular to a shock absorption device for a washing machine and a washing machine. Background technique [0002] When the dehydration of the fully automatic washing machine starts and runs, the outer tub will shake or swing as the motor starts, causing relatively large vibrations and noises. Therefore, in order to weaken the vibration and noise when the washing machine is dehydrated, the existing fully automatic washing machine is generally equipped with a shock absorber. A shock absorbing spring is arranged in the shock absorbing device, and when the outer barrel shakes or swings, the shock absorbing device relieves the eccentricity of the outer barrel through the buffering effect of the shock absorbing spring, thereby achieving the purpose of shock absorption. But along with the development and progress of washing machine, when the eccentricity of washing mac...

AI Technical Summary

Problems solved by technology

Some have added a sliding damping structure on the basis of the shock-absorbing spring, but the sliding damping force provided is too small to effectively achieve the effect of shock-absorbing and noise-reducing

There is also a friction rubber piece added between the sliding damping support seat and the upper bracket, but this structure has high cost and poor reliability. After a long wear time, the frictional damping force will be lost slowly
