The following describes a drum having a self-cleaning function according to the present invention in detail with reference to the accompanying drawings:
As shown in fig. 1 and 3, a drum having a self-cleaning function according to the present invention is coaxially installed inside an outer tub 2 of a washing machine and is freely rotatable, and a lifting device 9 is installed on an inner wall of the drum, and the lifting device 9 has a movable portion which is in contact with the inner wall of the outer tub 2 during washing and/or rinsing and is separated from the inner wall of the outer tub 2 during dehydration.
the lifting device 9 of the invention not only has the functions of lifting and beating the clothes by the lifting device on the traditional washing machine and improves the washing effect of the clothes, but also has the movable part of the lifting device 9 of the invention which can realize the self-cleaning function of the drum. Therefore, the invention improves the existing mechanism, realizes the self-cleaning function of the roller, has less influence on the existing roller structure and is easier to popularize in the market.
Specifically, in the washing and/or rinsing process of the drum of the invention, the movable part of the lifting device 9 is in contact with the inner wall of the outer drum 2 and is in contact friction with the inner wall of the outer drum 2 under the driving of the rotation of the drum, so as to realize the cleaning effect on the inner wall of the outer drum 2; during the dehydration, the movable part of the lifting device 9 is separated from the inner wall of the outer tub 2, preventing the generation of noise or damage to the tub wall during the dehydration by the high-speed rotation of the drum.
Therefore, the drum of the invention not only has no influence on the washing, rinsing and dewatering processes of the drum washing machine, ensures the working stability of the drum washing machine, but also can realize the self-cleaning function of the inner wall of the outer drum 2, effectively avoid the residue of impurities such as dirt, mould, virus and the like on the inner wall of the outer drum 2 of the drum washing machine, ensure that clothes have better washing effect and greatly improve the use experience of users.
how to realize the lifting device 9 of the invention has a part fixed on the inner wall of the roller and another part movable to realize the self-cleaning function is the key of the technical problem to be solved by the invention. Therefore, as a preferred embodiment of the present invention, the lifting device 9 of the present invention comprises a second lifting device 902, the second lifting device 902 is rotatably mounted on the inner wall of the drum; the second lifting means 902 is in contact with the inner wall of the tub 2 during washing and/or rinsing and is separated from the inner wall of the tub 2 during dewatering.
The second lifting device 902 of the present invention is rotatably installed on the inner wall of the drum, and the rotation of the second lifting device 902 is mainly driven by an external force.
Specifically, a driving mechanism may be separately provided, the driving mechanism is connected to the second lifting device 902, and the driving mechanism is controlled by a control program to operate, so as to further control the second lifting device 902 to rotate towards the inner wall of the tub 2 during the washing and/or rinsing process, contact with the inner wall of the tub 2, and rotate back into the drum during the dewatering process, so as to be separated from the inner wall of the tub 2. By providing a drive mechanism to drive the second lifting device 902 to rotate, it is easier to control and the lifting device 902 can be actuated as desired.
The present invention provides a realization mode with a simpler structure according to the washing characteristics of the drum washing machine, and specifically, an elastic support assembly 11 for supporting the second lifting device 902 is installed between the second lifting device 902 and the inner wall of the drum, the elastic support assembly 11 is pressed by the second lifting device 902 to deform during the washing and/or rinsing process, and the elastic support assembly recovers the deformation to support the second lifting device 902 to reset during the dehydration process.
the elastic supporting component 11 of the present invention has a certain elastic supporting force, and in a normal state, the elastic supporting component 11 supports the second lifting device 902 to be in a natural state, i.e. to be located inside the drum. When washing or rinsing, the laundry presses the force-bearing surface of the second lifting device 902 by controlling the rotation direction and the rotation speed of the drum, the elastic supporting component 11 deforms due to the pressing of the laundry, and the second lifting device 902 overcomes the elastic supporting force of the elastic supporting component 11 and rotates towards the inner wall side of the outer tub 2, so that the second lifting device 902 is in contact with the inner wall of the outer tub 2. In the dehydration state, the rotation direction and the rotation speed of the drum are controlled, so that the stress surface of the second lifting device 902 is not stressed by the pressure of the clothes or the pressure is very small, the second lifting device 902 is reset to be separated from the inner wall of the outer cylinder 2 under the action of the elastic supporting force of the elastic supporting component 11, and the second lifting device 902 keeps a natural state under the action of the elastic supporting force of the elastic supporting component 11, thereby ensuring the smooth dehydration process.
As a preferred embodiment of the present invention, the elastic support assembly 11 may be an elastic member such as a torsion spring.
Therefore, the second lifting device 902 of the present invention has only one force-bearing surface and only bears the pressure from one direction, so that the rotation of the second lifting device 902 can be controlled by controlling the rotation direction and the rotation speed of the roller. However, in the actual operation of the drum washing machine, the drum rotates in two directions to achieve better washing effect, so the present invention needs to solve the problem of the pressure in the other direction acting on the second lifting device 902.
As a preferred embodiment of the present invention, the lifting device 9 further comprises a first lifting device 901 fixedly installed on the inner wall of the drum, the first lifting device 901 is disposed at one side of the second lifting device 902 and blocks the side of the second lifting device 902 from being pressed.
According to the invention, the first lifting device 901 is arranged on one side of the second lifting device 902, so that the first lifting device 901 blocks the side of the second lifting device 902 from being pressed, and therefore, the second lifting device 902 only bears the pressure in the same direction, and the pressure in the other direction is borne by the first lifting device 901.
Specifically, the second lifting device 902 has a force-bearing surface for bearing pressure in the same direction, and the first lifting device 901 has a force-bearing surface for bearing pressure in the opposite direction of the second lifting device 902.
Therefore, the first lifting device 901 and the second lifting device 902 of the present invention respectively bear the pressure in two directions, and the rotation control of the second lifting device 902 can be realized by controlling the rotation direction and the rotation speed of the roller.
in order to enhance the cleaning effect of the second lifting means 902 of the present invention on the inner wall of the outer cylinder 2, as a preferred embodiment of the present invention, a cleaning means 10 is provided on the side where the movable part of the lifting means 9 contacts with the inner wall of the outer cylinder 2; preferably, said cleaning means 10 are removably mounted on the movable part of the lifting means 9; still more preferably, the cleaning device 10 is a flexible bristle.
The flexible bristles of the present invention may be made of elastomers such as rubber, polyurethane, etc.; can be made of fiber, such as natural fiber, chemical fiber, etc.; and can also be made of metal, such as stainless steel, various alloys and the like.
As shown in fig. 4, in the natural state or the dehydration state, the second lifter 902 is not pressed, and the first lifter 901 and the second lifter 902 are in point contact or line contact, so that the first lifter 901 and the second lifter are in close contact, and the laundry is prevented from being pinched by a gap between the first lifter and the second lifter. As shown in fig. 5, in the washing or rinsing state, the second lifters 902 are pressed to be rotated toward the inner wall side of the tub 2, and in order to prevent the first lifters 901 from blocking the rotation of the second lifters 902, a cavity is provided inside the first lifters 901 on the side contacting the second lifters 902.
As shown in fig. 3, each set of lifting devices 9 of the present invention is composed of a first lifting device 901 and a second lifting device 902, wherein the first lifting device 901 is fixed on the inner wall of the drum and is stationary. And a part of the second lifting means 902 is rotatably connected to the inner wall of the drum and has a certain range of motion, and flexible bristles are arranged on the side of the second lifting means 902 contacting with the inner wall of the outer drum 2. Generally, the flexible bristles are stored in the space between the first lifting device 901 and the second lifting device 902, and only after the clothes exert pressure on the second lifting device 902, the second lifting device 902 moves to drive a series of flexible bristles to move, so that the flexible bristles can contact the inner wall of the tub 2 to clean the inner wall of the washing tub 2.
The working principle of the present invention is further explained with reference to fig. 4 and 5 below:
as shown in fig. 4, the second lifting device 902 is in a state that no pressure is applied or the applied pressure cannot deform the elastic support component 11.
In this case, the second lifting means 902 is fixed, and the elastic support member 11 supports the second lifting means 902 at one end and supports the inner wall of the drum at the other end.
In this case, the flexible bristles on the second lifting means 902 are stored in the space between the first lifting means 901 and the second lifting means 902.
As shown in fig. 5, the second lifting device 902 is deformed by the elastic support member 11 under the pressure.
The applied pressure is large enough to deform the elastic support member 11, so that the second lifting device 902 can move at an angle a.
when the moving angle of the second lifting device 902 reaches a or is smaller than a, the flexible bristles carried by the second lifting device 902 will partially or completely contact the inner wall of the tub 2 to perform tub cleaning on the inner wall of the washing tub 2 of the washing machine.
Example one
As shown in fig. 6 and 7, the present embodiment is different from the above embodiments only in that: in this embodiment, one side of the first lifting device 901, which is in contact with the second lifting device 902, is an arc concave surface, and one side of the second lifting device 902, which is in contact with the first lifting device 901, is an arc convex surface; the curved convex surface moves along the curved concave surface to bring the second lifting means 902 into/out of contact with the inner wall of the outer cylinder 2.
Therefore, the first lifting device 901 is in arc contact with the second lifting device 902, and the second lifting device 902 moves along the arc surface, so that the first lifting device 901 and the second lifting device 902 are in contact all the time in the movement process, and clothes are prevented from being damaged due to the fact that a gap is generated between the second lifting device 902 and the first lifting device 9011 when the second lifting device 902 rotates.

A washing method, in the washing and/or rinsing procedure, the drum 3 rotates alternatively in two directions, the time of the drum 3 rotating in one direction is longer than the time of the drum 3 rotating in the other direction; in the dehydrating process, the drum 3 is rotated only in one direction at a high speed.
Specifically, in the washing method of the present embodiment, in the washing and/or rinsing process, the drum 3 rotates clockwise and rotates counterclockwise alternately, the time of the clockwise rotation of the drum 3 is greater than or equal to 3/4T, the time of the counterclockwise rotation of the drum 3 is less than or equal to 1/4T, and in the spin-drying process, the drum 3 rotates clockwise at a high speed;
When the drum 3 rotates clockwise, the first lifting device 901 lifts the laundry, and the second lifting device 902 is not or only slightly stressed;

During the washing and/or rinsing process, only a small fraction of the time (1/4T), for example 5min, the drum 3 is operated counter-clockwise and the lifting of the laundry is mainly effected by the second lifting means 902. Because the second lifting device 902 is movable, the clothes can be lifted and the resistance of the clothes can form pressure on the surface of the second lifting device 902, so that the second lifting device 902 moves, the flexible bristles are ejected and contact with the inner wall of the washing outer cylinder 2 for cylinder cleaning.
In the dewatering process of the washing machine, the washing drum 3 is operated clockwise, the second lifting device 902 is no longer stressed or is stressed a little, and the flexible bristle elastic strip is stored in the space between the first lifting device 901 and the second lifting device 902, which will not affect the dewatering.
