A three-channel balance ring

Abstract

The invention discloses a three-channel balancing ring. The three-channel balancing ring is characterized in that a plurality of separating plates are arranged at intervals on a cross section of a circular inner cavity of the balancing ring along the circumference, three independent overflowing channels are arranged on separating plates, centers of three overflowing channels are separately located at different circumferential radial positions of the circular inner cavity, three overflowing channels comprise the high-speed flow channel on the outer circumference, the low-speed flow channel on the inner circumference and the transitional flow channel between the outer circumference and the inner circumference, the flow area of the low-speed flow channel is larger than that of the transitional flow channel, the flow area of the transitional flow channel is larger than that of the high-speed flow channel, the high-speed flow channel is an unobstructed channel without flow choking ribs, transitional flow channel flow choking ribs are arranged inside the transitional flow channel, and low-speed flow channel flow choking ribs are arranged inside the low-speed flow channel. By the aid of the three-channel balancing ring, the good rectification capability can be guaranteed during low-speed and high-speed operations, and stable switching between the low speed and the high speed can be achieved.

Description

technical field [0001] The invention relates to a balance ring structure in a washing machine. Background technique [0002] The realization of the dehydration function of the double-tub washing machine is that the dehydration motor rotates at a high speed through the transmission of the pulley. [0003] When the clothes are put into the dehydration bucket, the center of gravity cannot completely coincide with the center of the bucket body, so the unbalanced clothes may cause the dehydration bucket to rotate out of concentricity during the dehydration operation, which will hit the box, and even cause damage to the motor in severe cases. The function of the balance ring is to move the liquid in the balance ring to the side opposite to the fixed eccentricity when the center of gravity of the dehydration bucket is eccentric due to uneven placement of clothes, so as to reduce the eccentricity of the system and ensure normal dehydration operation. [0004] The washing machine de...

Problems solved by technology

[0007] The third is to install a rib-blocking balance liquid balance ring in the flow channel. Although it can block the rapid flow of the balance liquid when starting at a low speed and does not hit the barrel when starting, but after reaching a high speed, due to the flow-blocking effect of the ribs, the deviation will not be corrected. capacity is affected;

[0008] The fourth is the double-channel balance ring, which has two flow channels, the inner flow channel and the outer flow channel. The inner flow channel is a wider low-speed starting flow channel, which can correct the deviation well when starting, and the outer side is a high-speed flow channel with a small cross-section. The channel helps to improve the deviation correction of the upper part of the barrel. At the same time, it has a good system deviation correction ability when it enters high-speed operation. However, the deviation correction ability of this structure is limited by the size and shape of the flow channel section. If the inner channel section If the area is larger than 2 times that of the outer runner, it will hit the barrel when running at high speed. If the cross-sectional area of ​​the inner runner is less than 1.5 times that of the outer runner, the deviation correction ability will be limited.
