Abstract

The invention provides a baffle ring for noise reduction of a washing machine. The baffle ring is in an annular curved surface shape and comprises an outer ring surface and an inner ring; the outer ring surface is matched with the inner wall of a washing barrel of the washing machine; the inner ring comprises an upper inclined surface, a lower inclined surface and a transition surface; the upper inclined surface and the lower inclined surface are connected with the outer ring surface separately; and the transition surface is arranged at the junction of the upper inclined surface and the lower inclined surface. The baffle ring is in a curved surface shape and is arranged in the washing barrel of the washing machine, so that water flow noise caused by up-down and left-right turning of the water surface due to repeated rotation of an impeller can be reduced, and noise and vibration caused by water flow impact are reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical product manufacturing, in particular to a retaining ring for noise reduction of a washing machine. Background technique [0002] The pulsator washing machine completes the washing of clothes through the joint action of detergent, water and mechanical force. The mechanical force of the pulsator washing machine is mainly generated by the transmission parts of the washing machine driving the pulsator in the water in the bucket. Under the control of a certain time, the washing motor makes frequent positive and negative motions, and the pulsator of the transmission system also makes positive and negative motions, causing the washing liquid to generate a vortex flow that is constantly reversing, washing away the clothes, and continuously rolling the clothes. Stretching, rubbing and squeezing can make the dirt attached to the clothes peel off the clothes within a certain washing time, and then the clo...
