Dynamic shock-absorbing device for drum washing machine

Abstract

The invention discloses a dynamic vibration absorption device for a tumbling-cylinder washing machine, comprising balancing weights and dynamic vibration absorbers, two balancing weights are respectively arranged at left and right sides of the outer drum of the tumbling-cylinder washing machine, two dynamic vibration absorbers for absorbing the vibration of the tumbling-cylinder washing machine are respectively arranged at the balancing weights at left and right sides. The dynamic vibration absorbers are used for transferring the energy of a vibration system and absorbing the vibration of thetumbling-cylinder washing machine. The dynamic vibration absorber comprises a vibrator, springs, an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plate are arranged on the balancing weights, both ends of the vibrator are provided with springs, the vibrator is mounted on the upper cover plate and the lower cover plate via the springs arranged at the two ends.The invention is in no need of the balancing weights with large mass, can effectively control the vibration amount of the entire drum and absorb the vibration of the washing machine. The invention isadapted to a variety of tumbling-cylinder washing machines.

Description

technical field [0001] The invention relates to a shock absorber for a drum washing machine, in particular to a dynamic shock absorber designed using the principle of resonance and vibration absorption. Background technique [0002] Generally speaking, the washing machine is a device that uses the action of washing water and detergent to remove the dirt stuck in the clothes, pillows and other washings contained in the drum through the steps of washing, cleaning, dehydration, and drying. [0003] The washing method of the existing drum-type washing machine is: after putting the laundry, detergent, and water into the drum, when the drum rotates left and right, the lifter in the drum will drag the laundry upwards, and at the same time, it will fall under the action of gravity. , rely on the impact force to clean the washing. The drum-type drying washing machine includes: a shell 21 forming the appearance of the washing machine; an outer cylinder 22 is arranged inside the shell...

AI Technical Summary

Problems solved by technology

The disadvantages of this device are: 1. Due to the large counterweight, the weight of the drum is very large, and it is easy to damage the outer cylinder when it falls, which is poor in safety; 2. The washing machine produces a lot of noise when it is running; Heavy block structure, resulting in high overall price of the washing machine
