Description

Filtering device for outer barrel and outer barrel design applying same

Technical Field

The invention belongs to the technical field of washing machines, and particularly relates to a filtering device for an outer barrel and an outer barrel design applying the filtering device.

Background

The impeller washing machine is used as an agitating washing device, and the impeller rotates to drive water flow during operation, so that clothes are driven to rotate, and the effect similar to manual kneading is achieved. Because the inner barrel of the impeller is vertical, clothes are easy to wind and rub with the barrel wall, the impeller and other clothes during stirring, a large amount of water is needed to suspend the clothes, and the thread scraps of the clothes can flow along with the water.

Therefore, at least one thread scrap filtering device, such as a magic box (box-packed filter screen), a filter mesh bag and the like, is often arranged in the inner barrel of the pulsator washing machine. The filtering device drives water flow through the impeller, and the water flow passes through the filter so as to retain thread scraps in the filter. However, the conventional thread scraps bag and the thread scraps box are integrated on the inner barrel, a plurality of thread scraps are hung on the wall of the outer barrel during dehydration, and the outer barrel does not rotate along with the inner barrel during dehydration, so that more accumulated thread scraps are accumulated on the bottom of the outer barrel and the bottom of the inner barrel, and bacterial colonies are formed. After the impeller washing machine used for many years is disassembled, dark green spots can be seen at the bottoms of the outer barrel and the inner barrel, namely the reason why the thread scraps are not cleaned in time.
