Description

Washing machine balance ring, inner barrel and washing machine

Technical field

The invention belongs to the field of washing machines, and in particular to a balance ring, an inner tub and a washing machine of a washing machine.

Background technique

Ordinary automatic washing machine has many leaking holes on the bottom and side walls of the dewatering bucket (inner barrel). The water can be freely flowed into and out of the dewatering bucket. The drainage is very smooth and the dewatering efficiency is high, but when washing, between the outer tub and the dewatering bucket There is water, and the outer bucket is a water storage bucket. This part of the water cannot be used, which causes a large amount of water to be wasted. At the same time, dirt and bacteria are easily accumulated between the side walls of the inner and outer barrels, which is not good for human health.

In order to solve this problem, a washing machine with a non-porous inner tub has been developed. The entire inner tub is designed with a closed water. Only one dewatering hole is provided on the wall of the barrel below the balance ring, and no water is trapped in the middle and lower portions of the inner barrel wall. The leaking small holes are used to concentrate the washing and rinsing water in the inner tub, so that it is both a water washing bucket and a centrifugal dewatering bucket. The outer tub of the washing machine is actually only a collection of non-porous inner buckets which are drained when dewatering. aisle. Some of the bottom of the inner bucket is provided with a drain, and some of the bottom of the bucket is completely sealed. The washing machine with the drain port at the bottom of the barrel drains most of the water through the drain port when draining. When centrifugally dehydrating, the inner barrel rotates at a high speed, and the residual water in the clothes rises along the barrel wall of the non-porous inner barrel under the action of centrifugal force. A dewatering hole distributed under the barrel mouth and the balance ring is thrown into the outer tub, and the drain pipe collected to the bottom of the outer tub through the outer tub wall is discharged outside the machine. The washing machine with the bottom of the barrel is completely sealed, and the water in the inner tub is also discharged from the dewatering hole of the upper part of the barrel wall by controlling the rotation speed of the inner tub, and the dehydration is the same as the above. The washing machine saves water in the “sandwich” of the inner and outer barrels of the conventional washing machine, and the water saving effect can reach 50% or more on average. The washing machine, especially the washing machine with the bottom of the barrel completely sealed, is completely discharged by the dewatering hole in the upper part of the barrel wall, but the dewatering hole is arranged on the side wall, and under the balance ring, the drainage process is blocked by the balance ring, drainage Not smooth enough to affect drainage and dewatering efficiency.

Chinese Patent Application No. CN201210011789.1 discloses a sealed inner tub comprising an integrally connected side wall and a bottom, the side wall and the bottom are sealed, and a drain groove is arranged at the top of the side wall. A balance ring is disposed, and a plurality of notches are uniformly distributed around the bottom of the balance ring, and the notch forms the drainage groove, and the bottom of the inner barrel is provided with a mounting hole for the driving shaft of the driving device, and the outer circumference of the driving shaft and the mounting hole The surrounding is sealed and connected. When washing, the water flow fills the inner bucket. After the water level reaches the set water level of the washing machine, the pulsator rotates, the washing is completed, the inner barrel rotates at a high speed to generate centrifugal force, and the water flow in the inner tub and the moisture in the laundry are spirally spiraled. All are discharged through the drain groove of the inner tub. The washing machine During washing, the washing water is easily splashed into the outer tub by the dehydration hole under the balance ring due to the surge. When draining, the drainage efficiency is limited due to the influence of the balance ring.

The present invention has been made in view of the above.
