Problems solved by technology

Since the inner cylinder and the outer cylinder are set together, dirt is easy to accumulate between the inner and outer cylinders during the use of the washing machine; at the same time, in the washing mode, there will be more water between the inner and outer cylinders. On the one hand, it needs to consume more Too much water, on the other hand, the sewage between the inner and outer buckets is easy to contaminate the clothes, resulting in low washing efficiency and poor user experience

Embodiment 1

[0024] like Figure 1 to Figure 4 As shown in the figure, a drum washing machine is introduced in this embodiment. The drum washing machine includes a shell 2, and an inner drum 1 is arranged in the shell 2. The axis of the inner drum 1 extends horizontally or is gradually inclined downward from front to back. The inner drum 1 The front end is an annular front end cover 101 with an opening, and the rear end is a sealed inner cylinder bottom 102; there are no through holes on the wall of the inner cylinder 1, so that the interior of the inner cylinder 1 constitutes a sealed container with only the front part of the clothes drop opening. At the same time, a door cover 4 that can be opened outwards is installed at the front end of the drum washing machine shell 2, so as to close the annular front end cover 101 after the door cover 4 is closed. The purpose of putting clothes in the inner tub 1. The rear end of the inner tub 1 is installed in the drum washing machine shell 2 throu...

Embodiment 2

[0039] like figure 1 As shown, in this embodiment, the door cover 4 is also provided with an inner cylinder inner cover 6, and the inner cylinder inner cover 6 is connected with the door cover 4 through an elastic mechanism, so that after the door cover 4 is closed, the elastic mechanism is opposite to the inner cylinder. The inner cover 6 exerts an elastic force to drive the inner cover 6 of the inner cylinder to be fastened at the clothes drop opening of the annular front end cover 101, so that the clothes drop opening of the annular front end cover 101 is sealed and buckled by the inner cover 6 of the inner tube, so as to realize the inner sealing of the inner tube. , which is used to store the incoming water and drive the inner cylinder to rotate to wash the clothes with the water.

[0040] In this embodiment, the inner cylinder outer cover 5 and the inner cylinder inner cover 6 are sequentially installed on the inner side of the door cover 4 through the support shaft 8, o...

Embodiment 3

[0043] like figure 1 and Figure 4 As shown, in this embodiment, the center of the inner cylinder bottom 102 is installed on the inner cylinder support 3 via the rotating shaft 10, so that the inner cylinder 1 can rotate around the axis of the inner cylinder 1 under the action of the driving motor installed at the end of the rotating shaft 10; The rotating shaft 10 is hollow inside, one end of the hollow part is communicated with the drum 1 of the drum washing machine, and the other end is communicated with the water inlet pipe of the drum washing machine.

[0044] In this embodiment, the rotating shaft 10 is composed of three layers of sleeves sleeved in sequence from the inside to the outside. The inner layer of the sleeve 11 is connected to the water inlet pipe of the drum washing machine and constitutes a water inlet 14 that forms an inner cylinder. The flow channel between 11 and the middle layer casing 12 constitutes the air inlet 15 of the inner cylinder, and the flow ...

Abstract

The invention relates to a drum washing machine and a control method thereof. The drum washing machine includes an outer shell and an inner cylinder arranged in the outer shell. The inner cylinder includes an annular front end cover, an inner cylinder side wall and an inner cylinder bottom which are sequentially connected. The annular front end cover forms the clothes feeding port of the inner cylinder. The inner cylinder is also provided with a first positioning part; the outer shell is also provided with a switchable door cover, and the door cover is provided with a support shaft, an inner cylinder outer cover for opening and closing the drain outlet, and a door for opening and closing the clothes input port. The inner cover of the inner cylinder, the support shaft is arranged on the door cover, the outer cover of the inner cylinder and the inner cover of the inner cylinder can be rotatably installed on the support shaft, the outer cover of the inner cylinder can slide on the support shaft, and the door cover is also provided with a A driving mechanism for driving the movement of the inner cylinder outer cover, and the inner cylinder outer cover is also provided with a second positioning part snap-fitted with the first positioning part. Realize the reduction of washing water consumption, improve washing efficiency and improve user experience. Ring-shaped front-end cover.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a drum washing machine and a control method thereof. Background technique [0002] In the prior art, a drum washing machine generally includes an inner tub and an outer tub that are fitted with each other, the outer tub is sealed for holding water, the inner tub is used for storing clothes, and the inner tub is rotated to beat and wash the clothes; A dehydration hole is provided, so that the water in the outer cylinder flows into the inner cylinder through the dehydration hole to soak the clothes in the inner cylinder, the water in the inner cylinder flows out to the outer cylinder through the dehydration hole, and the moisture on the clothes in the inner cylinder is dehydrated when the inner cylinder rotates at a high speed. The holes are discharged to the outer tub to achieve the purpose of washing clothes. Since the inner tub and the outer tub are fitted ...
