Description

Washing machine

Technical Field

The invention belongs to the field of washing machines, and particularly relates to a washing machine.

Background

The conventional washing machine employs an inner tub and an outer tub in combination to perform washing and dehydration. Therefore, dirt is easily stored and accumulated between the inner barrel and the outer barrel of the traditional washing machine, and bacteria are bred to be not beneficial to body health. The existing washing machine without outer barrel combines a washing barrel and a water collecting device. The washing barrel body of the washing machine without the outer barrel is different from the inner barrel body of the traditional washing machine, and the inner barrel body is not provided with water holes in a regular distribution, so that washing water only exists in the inner barrel, when clothes are dehydrated, the inner barrel rotates at a high speed, and water in the inner barrel moves upwards due to high-speed rotation, so that the drainage problem during dehydration can be realized by designing a dehydration port above the washing barrel body. When water is thrown out from the dewatering opening, water flow is guided to enter the water collecting device through the dewatering flow passage, but the design of the existing dewatering flow passage influences the attractiveness of the washing barrel, and meanwhile, the space of the washing barrel is reduced under the condition that the thread scrap filter is arranged.

The present invention has been made in view of this situation.

The movable baffle 10 can swing towards the direction close to the second water through hole 32 under the impact of the water flow in the filtering chamber, and can block the passage between the second water through hole 32 and the filtering chamber when swinging to a preset angle. The water that gets into the filter chamber by the second of lid both sides crosses the water hole can only flow towards the first water hole of crossing under the effect of second baffle to avoid rivers to cross the water hole from the offside and flow out, improve thread scraps filter effect.

Further optionally, the preset angle of the movable baffle 10 swinging towards the direction close to the second water passing hole 32 to block the passage between the second water passing hole 32 and the filtering chamber is defined by the box cover, and the movable baffle is against the box cover 3 at the preset angle.
