Description

Washing machine

Technical Field

The invention belongs to the field of washing machines, in particular relates to a washing-free washing machine in which washing water does not flow across an inner barrel and an outer barrel, and particularly relates to a washing machine capable of filtering and collecting filings in a non-porous inner barrel.

Background

The washing machine in the prior art generally comprises an inner tub and an outer tub, wherein the inner tub is installed inside the outer tub, the outer tub is used for containing washing water, and clothes are placed in the inner tub; the inner barrel is internally provided with a washing structure such as a pulsator and the like, and the inner barrel and/or the pulsator are/is driven by a motor to rotate so as to generate washing water flow to wash clothes. In the washing process, the inner barrel is connected with the outer barrel through the dehydration holes arranged on the inner barrel, so that the inner barrel and the inner part of the outer barrel are filled with water, and therefore, the conventional washing machine in the prior art has three problems:

firstly, water is wasted, and only water in the inner barrel is needed in actual work;

secondly, bacteria grow, water at the joint of the inner barrel and the outer barrel cannot be completely discharged, and cannot be cleaned, so that bacteria grow on the outer barrel and pollute clothes after long-term use;

thirdly, the existence of the outer tub greatly reduces the capacity of the washing machine, and for the conventional washing machine, the whole structure of the washing machine can only be increased by the need of capacity expansion, so that the occupied space of users can be excessively occupied, and the washing machine is extremely unfriendly to small-sized users.

In order to overcome the problems, the applicant proposes a washing machine with a hole-free inner tub, which is provided with the inner tub as a closed container without a dehydration hole, so that washing water is contained in the inner tub, the inner tub has the dual functions of water containing and rotary washing, and the problem that the washing water flows between the inner tub and the outer tub and cannot clean and pollute a cavity between the inner tub and the outer tub is avoided.

However, as the pore-free inner barrel is a sealed inner barrel, the thread scraps wrapped in the washing water in the washing process are difficult to discharge; especially in the last dehydration stage, because the drainage water flow is weaker, the water after centrifugation needs to climb to the water outlet at the top of the inner barrel and then flow out, so that the drainage power is further weakened, a large amount of thread scraps are remained in the inner barrel, and the washing effect of the washing machine on clothes is greatly affected.

Meanwhile, the thread scraps filter of the existing washing machine cannot collect the thread scraps in an unlimited amount, has no function of timely cleaning when the washing machine performs clothes treatment every time, and is easy to generate the problems that the washing machine continues to run in a saturated state, and the thread scraps filter cannot collect the thread scraps in the barrel timely and effectively.

The present invention has been made in view of this.
