Detailed Description
A self-cleaning drum washing machine of the present invention is described in detail below with reference to the accompanying drawings:
as shown in fig. 1 and 2, the self-cleaning drum washing machine of the present invention comprises an outer drum 2 and an inner drum 4 coaxially and rotatably disposed inside the outer drum 2, wherein the inner drum 4 is mainly used for containing clothes and realizing washing and dehydration of the clothes through rotation, the inner drum 4 is disposed inside the outer drum 2, and the outer drum 2 is fixed with a box 1 of the washing machine; the side wall of the outer barrel 2 is provided with a groove 6, a cleaning block 9 is arranged in the groove 6, the cleaning block 9 is contacted with the outer wall of the inner barrel 4 in the washing process of the washing machine, and the cleaning block 9 is separated from the outer wall of the inner barrel 4 in the dehydration process.
According to the invention, the groove 6 is arranged on the side wall of the outer barrel 2, the floatable cleaning block 9 is arranged in the groove, after water is fed into the washing machine, the cleaning block 9 floats to be in contact with the outer wall of the inner barrel 4, the inner barrel 4 rotates in the washing process, and the cleaning block 9 slides in a friction manner relative to the inner barrel 4, so that the cleaning effect on the outer wall of the inner barrel 4 is realized; after the washing machine drains water, the buoyancy disappears, the cleaning block 9 falls down and is separated from the outer wall of the inner barrel 4, the washing machine carries out a normal dehydration procedure, and the clothes in the dehydration process are not thrown to water enough to enable the cleaning block 9 to float and then be discharged. The contact between the cleaning block 9 and the outer wall of the inner barrel 4 is sustainable contact and can also be floating type intermittent contact under the condition of being subjected to buoyancy. The invention has simple structure and realizes good self-cleaning function on the basis of not changing the basic structure of the existing washing machine.
Specifically, the cleaning block 9 floats to the position contacting with the outer wall of the inner drum 4 when the drum washing machine washes, keeps floating contact with the outer wall of the inner drum 4 under the influence of the buoyancy of washing water in the drum and the rotation of the inner drum filled with clothes, and dirt on the outer wall of the inner drum 4 is separated under the friction action of the cleaning block 9, so that the cleaning action on the outer wall of the inner drum 4 is realized. It should be understood by those skilled in the art that the washing of the washing machine according to the present invention includes not only a washing process but also a rinsing process. When the cleaning block 9 is dehydrated in the drum washing machine, the inner drum 4 rotates at a high speed, if the cleaning block 9 is still in contact with the outer wall of the inner drum 4 at this time, certain influence is generated on the high-speed rotation of the inner drum 4, and the cleaning effect of the cleaning block 9 is deteriorated due to the fact that the cleaning block 9 is worn out by accelerating the high-speed rotation of the inner drum 4, and moreover, due to the fact that the inner drum 4 rotates at a high speed, the cleaning block 9 is in contact with the cleaning block to generate certain noise, so that the use feeling of a user is greatly reduced. Therefore, the cleaning block 9 of the present invention is separated from the outer wall of the drum 4 during the dehydration process of the washing machine.
In order to ensure a good self-cleaning effect of the washing machine of the present invention, the cleaning block 9 should be arranged as far as possible along the axial direction of the outer wall of the tub 4, so that the cleaning block 9 can clean the entire outer wall of the tub 4.
Therefore, how to realize the floating of the cleaning block 9 and control the cleaning block 9 to contact with the outer wall of the inner drum 4 when the washing machine washes, and to separate from the outer wall of the inner drum 4 when the washing machine dehydrates is the key of the present invention. The invention utilizes the working characteristics of the drum washing machine, creatively adopts a brand new mode to realize that the cleaning block 9 floats at the bottom of the outer drum 2 and is contacted with/separated from the outer wall of the inner drum 2. Specifically, the following technical scheme is adopted:
the groove 6 is arranged at the lower part of the side wall of the outer cylinder 2, the shape of the cleaning block 9 is matched with that of the groove 6, the distance between the wall of the inner cylinder and the opening of the groove is less than the height of the cleaning block 9, after water is fed, the cleaning block 9 floats at the bottom of the outer cylinder 2 under the action of buoyancy force and is contacted with the outer wall of the inner cylinder 4 (refer to fig. 3 and 4), and after water is discharged, the cleaning block 9 is separated from the outer wall of the inner cylinder 4 under the action of self gravity (refer to fig. 1 and 2). The invention utilizes the characteristic that the outer cylinder and the inner cylinder are required to be filled with washing water when the roller washing machine washes, and the washing water in the outer cylinder and the inner cylinder is discharged before dehydration, does not need to be additionally provided with a driving device, and realizes the movement of the cleaning block 9 at the bottom of the outer cylinder 2 by utilizing buoyancy. Specifically, when the washing machine washes, washing water is injected into the outer barrel 2, and along with the increase of the injection amount of the washing water, the cleaning block 9 floats from the groove 6 under the buoyancy effect of the washing water and is in contact with the outer wall of the inner barrel 4, the washing water is always stored in the outer barrel 2 in the whole washing process, and the cleaning block 9 is influenced by the buoyancy of the washing water and the rotation of the inner barrel filled with clothes to keep floating contact, so that the cleaning effect on the outer wall of the inner barrel 4 is realized. Before the washing machine dewaters, will start earlier the drainage procedure, the washing water in the urceolus 2 is discharged, and cleaning block 9 is because of no longer receiving buoyancy, in falling back to recess 6 because of self action of gravity to with the separation of inner tube 4 outer wall, clean block 9 can not produce the noise with inner tube 4 friction among the dehydration process.
In order to ensure that the cleaning block 9 can float upwards to contact with the outer wall of the inner cylinder 4 under the action of buoyancy, and according to the structural characteristics of the drum washing machine, because the inner cylinder 4 and the outer cylinder 2 of the drum washing machine are transversely arranged, after washing water is injected into the outer cylinder 2 of the drum washing machine, the washing water can preferentially fill the parts, close to the bottom of the washing machine, of the outer cylinder 2 and the inner cylinder 4, and therefore the groove 6 is arranged on the side wall of the outer cylinder 2, close to the bottom of the washing machine.
Moreover, the cleaning block 9 is made of rubber materials with certain density, the density of the cleaning block 9 is smaller than that of the washing water, and the cleaning block 9 can float upwards to keep contact with the outer wall of the inner barrel 4 under the buoyancy action of the washing water only if the density of the cleaning block 9 is smaller than that of the washing water. Preferably, the cleaning block 9 of the present invention can be a rubber floating block made of rubber, and the cleaning block 9 is made of rubber material, mainly because the density of the rubber is lower than that of water, and the cost of the rubber is lower, and the rubber has good elasticity, which is more beneficial to cleaning the outer wall of the inner cylinder 4.
There are other ways of moving the cleaning block 9 that can be realized by the present invention, for example, the movement of the cleaning block 9 on the bottom of the outer cylinder 2 can be realized by mechanical means, including a way of driving by additionally arranging a driving device or other mechanical transmission means.
In addition, it is a mechanical way that is easy to think and realize that a driving device is arranged to drive the cleaning block 9 to move and control the driving device to move according to requirements through a control program, specifically, the cleaning block 9 is connected with a driving device, and the driving device drives the cleaning block 9 to approach the outer wall of the inner barrel 4 to be contacted with the outer wall of the inner barrel 4 in the washing process of the washing machine and separate from the outer wall of the inner barrel 4 in the dehydration process.
In a preferred embodiment of the invention, the driving device is a push-pull motor or a wax motor, and the connecting part of the driving device and the cleaning block 9 is sealed with the groove 6. The motor shaft of the push-pull motor can realize linear push-pull motion, and mainly utilizes the basic principle of a worm gear; the wax motor is a drive device consisting of a positive temperature coefficient thermistor (PTC) mounted on a sealed container filled with solid wax. When the solid wax is heated to a controllable temperature by the energized thermistor, the solid wax melts and expands, thereby driving a spring-loaded piston outward. This piston may pull the load inward or outward depending on the orientation of the container within the wax motor housing and the configuration of the spring. When the thermistor is de-energized, the liquid wax cools and the spring returns the piston to its original position. Meanwhile, in order to ensure the tightness of the outer cylinder 2, when the cleaning block 9 is driven by a driving device, attention needs to be paid to sealing.
In order to ensure that the cleaning block 9 of the invention has a cleaning function, the cleaning function of the outer wall of the inner cylinder 4 is ensured to the maximum extent. The arrangement position and the arrangement mode of the grooves 6 are of great importance, and specifically, the number of the grooves 6 is at least one, and the grooves can be specifically arranged according to actual design requirements.
In order to clean the whole outer wall of the inner cylinder 4 as much as possible, the length of the groove 6 is 0.5-1.0 time of the axial length of the cylinder body of the inner cylinder 4; preferably, the length of the groove 6 is the same as the length of the inner cylinder barrel, and the two ends of the groove correspond to the two ends of the inner cylinder barrel, and further preferably, the groove 6 should be arranged along the axial direction along the side wall of the outer cylinder 2.

The height of the cleaning block 9 is larger than the distance between the outer cylinder 2 and the inner cylinder 4. Therefore, the cleaning block 9 can be ensured to play a cleaning role, and the phenomenon that the cleaning block 9 enters the space between the inner barrel 4 and the outer barrel 2 due to the over-small height and generates noise in the rotating process of the inner barrel 4 or cannot contact with the outer wall of the inner barrel 4 due to the over-small height to play a cleaning role to influence the cleaning effect can be prevented.
In a preferred embodiment of the present invention, in order to further improve the cleaning effect of the cleaning block 9, the surface of the cleaning block 9 on the side contacting with the outer wall of the inner cylinder 4 is a cambered surface, and the cambered surface is matched with the outer wall of the inner cylinder 4. The contact area of the cleaning block 9 and the outer wall of the inner barrel 4 can be increased by the arrangement, the cleaning effect is improved, and the appearance of the cleaning block and the outer wall of the inner barrel are matched to be more beneficial to cleaning dirt.

As shown in fig. 3 and 4, when the self-cleaning drum washing machine of the present embodiment performs washing, the washing water is injected into the inner tub 4 and the outer tub 2, and the washing water exists at the bottom of the inner tub 4 and the outer tub 2, so that the cleaning block is immersed in the washing water, and the density of the cleaning block 9 is less than that of the washing water, so that the cleaning block 9 floats up to contact with the outer wall of the inner tub 4 by the buoyancy of the washing water. Because the inner cylinder 4 rotates continuously in the washing process, the cleaning block 9 is in floating contact with the outer wall of the inner cylinder 4, so that dirt on the outer wall of the inner cylinder 4 is separated under the friction action of the cleaning block 9, and the cleaning effect on the outer wall of the inner cylinder 4 is realized.
As shown in fig. 1 and 2, before the self-cleaning drum washing machine of the present embodiment performs dewatering, the drainage procedure is started first, the washing water in the outer tub 2 is drained, the cleaning block 9 is no longer subjected to buoyancy, and falls back into the groove 6 due to its own gravity, so as to be separated from the outer wall of the inner tub 4, and the cleaning block 9 does not rub against the inner tub 4 to generate noise during dewatering.
The side surface that the cleaning block 9 of this embodiment contacted with inner tube 4 outer wall is the cambered surface, and this cambered surface and inner tube 4 outer wall phase-match can increase the area of contact of cleaning block 9 and inner tube outer wall like this, have strengthened the clean effect of cleaning block 9 to inner tube 4 outer wall.
The present embodiment may be further combined with the second embodiment, the third embodiment, the fourth embodiment, or the fifth embodiment.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
