Embodiment 1

[0064] Such as Figure 6 and Figure 7 As shown, the difference between this embodiment and the above-mentioned embodiments is only that: the side of the first lifting device 901 in this embodiment that is in contact with the second lifting device 902 is an arc-shaped concave surface, and the side of the second lifting device 902 that is in contact with the second lifting device 902 is an arc-shaped concave surface. The contact side of a lifting device 901 is an arc-shaped convex surface; the arc-shaped convex surface moves along the arc-shaped concave surface to realize the contact / separation between the second lifting device 902 and the inner wall of the outer cylinder 2 .

[0065] This makes the arc contact between the first lifting device 901 and the second lifting device 902, and the second lifting device 902 moves along the arc surface, so that the two are always in contact during the movement, preventing Clothes are pinched due to the gap generated between the rotation...

Embodiment 2

[0067] This embodiment provides a washing machine with a drum with a self-cleaning function as described in the above specific embodiments, including an outer drum 2, a drum 3 with a self-cleaning function, and the drum 3 is coaxially installed inside the outer drum 2 and can rotate freely. The lifting device 9 includes a plurality and is installed along the axial direction of the drum 3, the second lifting device 902 has only one force bearing surface set towards the clockwise rotation direction of the drum, and the second lifting device 902 has at least A force bearing surface is provided towards the anticlockwise rotation direction of the drum.

[0068] The invention of the washing machine of this embodiment can realize self-cleaning of the inner wall of the outer cylinder 2 during the washing and / or rinsing process, and can effectively avoid the residue of dirt, mold, virus and other impurities on the inner wall of the outer cylinder 2 of the drum washing machine. Therefor...

Embodiment 3

[0073] This embodiment provides a kind of washing method, described washing method is used in the washing machine of embodiment 2, specifically, comprises the following technical scheme:

[0074] A laundry method, in the washing and / or rinsing program, the drum 3 rotates alternately in two directions, and the time for the drum 3 to rotate in one direction is longer than the time for the drum 3 to rotate in the other direction; in the dehydration program, the drum 3 only Perform one-way high-speed rotation.

[0075] Specifically, in the laundry method of this embodiment, in the washing and / or rinsing procedure, the drum 3 rotates clockwise and counterclockwise alternately, the time for the drum 3 to rotate clockwise is greater than or equal to 3 / 4T, and the drum 3 rotates counterclockwise The time is less than or equal to 1 / 4T. In the dehydration program, the drum 3 runs clockwise at high speed;

[0076] When the drum 3 rotates clockwise, the first lifting device 901 lifts the...

Abstract

The invention provides a drum with a self-cleaning function. The drum is coaxially installed in an outer drum of a washing machine and can rotate freely; the inner wall of the drum is provided with a lifting device; the lifting device has a movable part which is in contact with the inner wall of the outer drum in a washing and / or rinsing process and is separated from the inner wall of the outer drum in a drying process. The invention also provides a washing machine with the drum and a washing method. The drum has no influence on washing, rinsing and drying processes of a drum washing machine, guarantees the working stability thereof, achieves a self-cleaning function for the inner wall of the outer drum, can prevent impurities such as dirt, mould and viruses from remaining on the inner wall of the outer drum of the drum washing machine, achieves a better clothes washing effect and improves the using experience of users.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a drum with self-cleaning function, a washing machine and a washing method. Background technique [0002] A traditional drum washing machine is composed of a stainless steel drum, a plastic outer cylinder, a motor, a transmission shaft, a perspective window, a sealing gasket, a drain pump and a casing. The washing method of the drum washing machine is designed to imitate the principle of hitting the clothes with a hammer. The mechanical work of the motor is used to make the drum rotate. The clothes are continuously lifted and dropped in the drum, and then lifted and dropped again. The combined effect makes the clothes wash clean. [0003] Such as figure 2 As shown, in the drum structure of the existing drum washing machine, a large number of through holes 302 are distributed on the drum 3. The through holes 302 are for the water in the outer drum to enter the drum thro...
