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...
