Problems solved by technology

Therefore, in general, the good vibration and noise reduction design of the drum machine is mostly reflected in the reasonable optimization of the structure, the best damper, the good performance of the suspension spring and the cooperation of auxiliary sound-absorbing and noise-reducing materials. However, these existing designs are costly. The cost is relatively high, and when a low-cost counterweight device is used, its vibration and noise reduction effect is not ideal

Embodiment 1

[0050] Such as Figure 1-Figure 3 As shown, the embodiment of the present invention introduces a damping counterweight. The counterweight 1 is provided with at least one hollow chamber 3 , and at least one mounting hole 2 is provided through the upper end and the lower end of the counterweight 1 respectively. The hollow chamber is filled with a certain volume of damping particles, and the fastener fastens the counterweight to the outer cylinder of the washing machine through the installation hole.

[0051] In this embodiment, the counterweight 1 is an arc-shaped flat sheet structure extending vertically, the inner side of the counterweight 1 is a regular semicircle, and the upper and lower ends of the counterweight 1 have the same thickness. The part is lower than both ends; when the counterweight 1 is fixedly installed on the outside of the outer cylinder 5 of the washing machine through fasteners, the inner side of the counterweight 1 can fit well with the outer side of the ...

Embodiment 2

[0058] Such as Figure 4-Figure 5 As shown, a layer of shell 6 is arranged outside the counterweight 1, and the shell 6 completely covers the entire counterweight 1. At the same time, there is a gap between the inner surface of the shell 6 and the outer surface of the counterweight, that is to say, the counterweight The gap between the outer surface of the weight 1 and the inner side of the casing 6 constitutes a hollow chamber, and a certain amount of damping particles 4 are filled in the hollow chamber formed by the gap. During the working process of the washing machine, the inner surface of the casing 6 and the The damping particles 4 between the outer surfaces of the counterweight 1 will also vibrate, and collisions will occur between the damping particles, between the damping particles and the end face of the counterweight and the inner wall of the housing, and consume the washing machine together with the damping particles in the hollow chamber. The kinetic energy genera...

Embodiment 3

[0065] Such as Figure 6 As shown, in the embodiment of the present invention, the outer surface of the counterweight 1 is provided with at least one concave groove inwardly, and the outer wrapping of the counterweight is fixed with a casing, and the casing at least seals and covers the opening of the groove, so that The housing 6 seals the groove that covers the opening to form a hollow chamber 3, and the hollow chamber formed by the groove is filled with damping particles 4; at the same time, the hollow chamber 3 formed by the groove does not communicate with the adjacent installation hole 2, and the hollow chamber 3 is hollow. There is a certain distance between the four walls of the chamber 3 and the inner side wall of the adjacent mounting hole 2 or the outer surface of the counterweight 1, and there is also a certain distance between the bottom of the hollow chamber 3 and the bottom surface of the counterweight 1, and the upper part of the hollow chamber 3 The end face i...

Abstract

The invention discloses a drum washing machine provided with damping counterweights. The drum washing machine comprises an outer drum of the washing machine and the counterweights assembled on the outer drum of the washing machine, wherein at least one hollow chamber is formed in each counterweight and is at least partially filled with damping particles. The chambers are formed in the counterweights and filled with the damping particles, during working of the washing machine, the washing machine generates vibration to drive the damping particles in the counterweights to vibrate, and the damping particles consume kinetic energy generated in the working vibration process of the washing machine by collision friction among the particles and between the damping particles and the walls of the hollow chambers, so that the purposes of vibration reduction and noise reduction are achieved. The drum washing machine has good vibration reduction and noise reduction effects, the damping particles have wide damping frequency domain and low generated additional mass, materials are saved, and the washing machine is suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of drum washing machines, in particular to a drum washing machine equipped with damping counterweights. Background technique [0002] Washing machine is an indispensable household appliance in people's daily life. With the improvement of people's living standards, washing machines are also changing in the direction of people's needs. Washing machines are becoming more and more intelligent, thinner and lighter, and have more functions, but the inevitable noise of washing machines during work is always a problem that the industry is trying to solve. [0003] At present, the low-priced washing machines on the market have poor vibration and noise control during the working process. This type of washing machine slows down the vibration during the working process of the washing machine and reduces the noise by adding counterweights. The design of the existing drum counterweight is relatively passive, and less consideratio...
