Self-cleaning device for dirt between barrels of washing machine

Abstract

The invention relates to the technical field of washing machines, in particular to a method and device for simultaneously cleaning the outer wall of an inner barrel and the inner wall of an outer barrel of a washing machine, i.e., a self-cleaning device of a washing machine, which comprises water passages arranged on the inner barrel and the outer barrel of the washing machine; the passages can be integrated with the inner barrel or the outer barrel during manufacturing and can also be independent passages; many intensive holes in the water passages can form water curtains when water in the passages has pressure; a water curtain sprayed from the outer / inner barrel can respectively clean the inner / outer barrel of the washing machine so as to achieve the purpose of thoroughly cleaning dirt between the inner barrel and the outer barrel of the washing machine; cleaning water can be directly pressurized by running water or a booster pump; the water passage on the inner barrel of the washing machine can rotate together with the inner barrel of the washing machine; water in the water passage of the inner barrel is introduced through a rotating shaft of the washing machine; and a dynamic seal water supply device is used when the water is introduced into the rotating shaft, and the dynamic seal water supply device is characterized by supplying water to the hollow part of the shaft when the shaft rotates. A barrel cleaning program can be preset in a computer program when the washing machine is produced, so that the self-cleaning of dirt between the barrels of the washing machine is programmed. The device can be applied to impeller type washing machines and drum type washing machines.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a method and a device capable of simultaneously cleaning the outer wall of the inner tub and the inner wall of the outer tub of the washing machine. Background technique [0002] After the washing machine is used for a certain period of time, a certain amount of dirt will be left on the inner wall of the outer barrel of the washing machine and the outer wall of the inner barrel, and some will also produce peculiar smell. If it is not cleaned in time, the washing machine may become a secondary pollution source. Chinese patent ZL200820062676.3 discloses a "washing machine self-cleaning and sterilizing device", which sprays tap water to the outer wall of the inner tub of the washing machine to rinse the outer wall of the inner tub through the dense small holes on the channel pipe located inside the outer tub of the washing machine when the washing machine enters the clothes ...

AI Technical Summary

Problems solved by technology

The above method can be used to clean the outer wall of the polluted inner tub of the washing machine, but it cannot clean the dirt on the inner wall of the outer tub well, and this method must be used when there are clothes left in the washing machine, so it is inevitable to bring the dirt between the inner and outer tubs. into the freshly washed clothes, causing secondary pollution
