Washing apparatus

Technical Field

The utility model belongs to the technical field of the washing, concretely relates to washing equipment.

Background

The washing machine is one of the most common domestic appliances at present, and there are two common types of the current washing machines, namely a pulsator washing machine and a drum washing machine. The impeller washing machine is provided with an impeller structure at the bottom of the washing inner barrel, and in the washing process, the impeller rotates in reciprocating forward and reverse directions, so that water flow in the barrel forms vortex flows with different directions, and the clothes are driven to roll along with the water flow, and meanwhile, mutual friction force can be generated, and the clothes washing effect is obtained. The drum washing machine utilizes the mechanical work of the motor to rotate the drum, drives the clothes to be continuously lifted to a high place in the drum and then fall off, and can wash the clothes through repeated reciprocating motion.

Compared with clothes with relatively large size such as outerwear and trousers, small clothes such as underwear, underpants and waistcoat are washed relatively frequently, the capacity of a traditional washing machine (such as a pulsator washing machine or a drum washing machine) is relatively large, if the small clothes are washed frequently, the small clothes are wasted, the small clothes are easy to breed bacteria, and the cleaning effect cannot meet the expectation due to the fact that the small clothes are usually small in size.

The small washing machine developed aiming at small clothes also appears on the market today, uses a washing drum to bear the clothes, and the drum wall has a protrusion, and the washing drum continuously rotates towards one direction, utilizes the protrusion to rub the clothes, and washes the small clothes. However, such a small washing machine may spin water by centrifugal rotation, but the whole washing machine may generate large vibration, and the service life of the washing drum may be affected by the collision between the washing drum and the housing.

Accordingly, there is a need in the art for a new washing device to solve the problems existing in the prior art that the above-mentioned small washing machine is prone to generate large vibration during centrifugal rotation dehydration and the service life of the washing drum is affected.
