The self-cleaning device not only can clean the filter screen 10, but also can clean the self, can reduce the cleaning frequency of the self-cleaning device, and is beneficial to improving the user experience.

The frame 20 has a plate-like structure, and the filter net 10 is provided inside the frame 20. And, the filtering net 10 moves in a ring shape inside the frame 20. The filter screen 10 of this embodiment may be a planar structure before assembly and then bent to form a ring-shaped structure. Alternatively, the ring structure may be directly produced. Wherein, under the condition that the filter screen 10 is of a plane structure, the packaging and the transportation are facilitated. The filter screen 10 is of a plane structure, and under the condition that the filter screen is bent to form an annular structure, the edges of two opposite ends of the filter screen 10 are connected through a clamping structure. It should be noted that the filter screen 10 with a ring structure not only can be moved conveniently to clean dust, but also the double-layer structure design can improve the filtering effect on the air flowing through. As shown in connection with fig. 4 to 6.

In the process of circular movement of the filter screen 10, each area of the filter screen 10 can be cleaned by the brush piece 40, the brush piece 40 cleans the filter screen 10, a cleaning blind area is avoided, and the cleaning effect of the filter screen 10 is improved.

The dust collecting box 30 is detachably connected to the frame 20 and located below the filter screen 10, and the brush 40 is disposed on the dust collecting box 30, so that when the brush 40 cleans the filter screen 10, the dust and lint coming off from the filter screen 10 can be accurately received by the dust collecting box 30. As shown in connection with fig. 4 and 5.

Taking the air conditioner hanging machine as an example, the filter screen 10 is transversely arranged at the air return port 141 at the top of the indoor machine. Among the filter screens 10 having the annular structure, the dust thickness of the upper filter screen 10 (i.e., the outermost filter screen 10) is greater than that of the lower filter screen 10. For convenience of description, the upper filter screen 10 of the filter screens 10 having the ring-shaped structure is defined as a surface to be cleaned.

Under the condition that the filter screen 10 needs to be cleaned, the brush part 40 is vertically arranged, the brush part 40 is positioned below the filter screen 10, and the brush part of the brush part is abutted against the filter screen 10. The filter screen 10 moves circularly, so that the filter screen 10 on the upper layer moves to the lower layer position, and the brush member 40 cleans the surface to be cleaned for the first time in the moving process.

In practice, the movement of the filter screen 10 may include a variety of patterns. For example, the first: the filter screen 10 on the upper layer moves to the lower layer, and after the first cleaning is completed, the filter screen moves in the reverse direction, so that the initial upper layer filter screen 10 is moved from the lower layer to the upper layer, and the cleaning of the surface to be cleaned can be realized twice. And the second method comprises the following steps: the filter screen 10 on the upper layer moves to the lower layer, and after the first cleaning, the filter screen continues to move, and the brush member 40 cleans the initial filter screen 10 on the lower layer. And the third is that: during the movement of the filter screen 10, the filter screen moves forward by N cm and then moves backward by N-1 cm. Thus, the forward movement is repeated. In the case that the filter net 10 moves circularly for one turn, the brush members 40 perform two times of cleaning of the filter net 10.

After the brush member 40 is used for a certain period of time, the rotation of the brush member 40 is controlled, the bristle part of the brush member 40 is crossed with the brush comb 50, and the bristle part of the brush member 40 is cleaned by the brush comb 50, that is, dust and lint attached to or wound around the bristle part of the brush member 40 are cleaned. Thereby, the cleaning of the brush member 40 is achieved so that the brush member 40 can clean the filter net 10 better. As shown in connection with fig. 7 and 8.

The rotation angle of the brush member 40 is within a range of 90 deg.. Under the condition that the brush comb 50 cleans the brush part 40, the brush part 40 can be rotated to the brush comb 50 for many times, so that the cleaning effect of the brush part 40 can be improved after a plurality of crossed combs.

The brush comb 50 is positioned in the dust collecting case 30, so that the dust and lint cleaned up by the brush unit 40 are directly received in the dust collecting case 30 to wait for processing.

Optionally, the brush comb 50 includes: a comb handle 501 detachably connected to the inside of the dust collecting case 30; a first comb tooth portion 502 provided at a side portion of the comb handle 501 and disposed opposite to the brush member 40; when the brush member 40 rotates to the first comb-tooth portion 502, the first comb-tooth portion 502 combs the brush member 40 so that the lint is separated from the brush member 40 and falls off.

The comb handle 501 is vertically arranged and detachably connected in the dust collecting box 30. Illustratively, a slot 301 is formed at the bottom of the dust collecting box 30, and the comb handle 501 is inserted into the slot 301. As shown in fig. 7, 9, 10 and 11.

The first comb teeth 502 are provided on the side of the comb handle 501. The comb handle 501 and the first comb tooth portion 502 are designed to be T-shaped. Thus, under the condition that the bristle part of the brush piece 40 is crossed with the first comb tooth part 502 to comb the batting, the stability of the first comb tooth part 502 in the carding process can be improved through the T-shaped structural design of the brush comb 50, and the shaking caused by stress is avoided.

The first comb teeth 502 may be disposed horizontally and vertically to the comb handle 501, or may be disposed obliquely to the comb handle 501. In the case of the inclined arrangement, the comb part of the first comb-tooth part 502 is disposed upward so as to cross the bristle part of the brush member 40.

The distance between the comb handle 501 and the brush member 40 is determined by the width of the first comb tooth portion 502, the width of the brush member 40, and the width of the bristle part of the brush member 40.

In practice, the brush comb 50 is stationary within the dust box 30. When the brush member 40 is rotated to the first comb teeth 502 of the brush comb 50, the brush member 40 is relatively passively cleaned by the first comb teeth 502.

Optionally, the brush comb 50 further comprises: a second comb-tooth portion 503 provided on the side of the comb handle 501 side by side with the first comb-tooth portion 502 and located below the first comb-tooth portion 502; the plurality of comb teeth of the first comb tooth portion 502 and the plurality of comb teeth of the second comb tooth portion 503 are arranged in a staggered manner. As shown in connection with fig. 10 and 11.

Through the cooperation use of second broach portion 503 and first broach portion 502, under the condition that brush piece 40 rotated to brush 50 once, can carry out twice clearance to brush piece 40 simultaneously through first broach portion 502 and second broach portion 503 to cleaning efficiency has been improved.

Illustratively, the brush member 40 rotates to the brush comb 50 and contacts with the first comb teeth 502, and after the bristle part of the brush member 40 passes through the first comb teeth 502, if a part of the bristle part has not fallen off after being combed by the first comb teeth 502, the brush member 40 passes through the first comb teeth 502 and contacts with the second comb teeth 503, and the part of the bristle part can be combed and separated by the second comb teeth 503.

In particular, the plurality of comb teeth of the first comb tooth portion 502 are offset from the plurality of comb teeth of the second comb tooth portion 503, so that the effect of the brush comb 50 in combing and removing the bristles from the brush 40 can be further improved.

Alternatively, the comb tooth length of the first comb-tooth portion 502 is smaller than the comb tooth length of the second comb-tooth portion 503. As shown in connection with fig. 10 and 11.

The brush comb 50 of the present embodiment can effectively comb off the flocks on the brush member 40 at different sizes and different positions by a long-short upper-lower layer design and a staggered comb teeth design of the first comb tooth portion 502 and the second comb tooth portion 503.

The first comb-tooth portion 502 is located above the second comb-tooth portion 503, and the comb-tooth length of the first comb-tooth portion 502 is smaller than the comb-tooth length of the second comb-tooth portion 503. In this way, in the case of combing the brush 40, a large amount of flocks on the upper end side of the brush 40 are cleaned by the first comb-tooth portion 502; then, the lint left on the end portion side and the other lint far from the end portion side are cleaned by the second comb-tooth portion 503. Wherein, the amount of the batting far away from the end side is lower than that of the batting at the end side, so that the length of the first comb-tooth part 502 is designed to be shorter, so that the resistance of the brush piece 40 in the contact carding process with the brush comb 50 can be reduced under the condition of ensuring the carding effect, and the production cost can also be reduced.

Optionally, the self-cleaning device further comprises: the electrostatic adsorption module 60 is disposed in the dust collecting box 30, and is located at two sides of the brush member 40 with the brush comb 50, respectively, and the electrostatic adsorption module 60 is used for adsorbing dust falling off after the filter screen 10 is cleaned by the brush member 40. As shown in connection with fig. 7 and 8.

During the cleaning process of the filter screen 10 by the brush member 40, part of the dust and lint on the filter screen 10 is directly transferred to the brush member 40, part of the dust falls into the dust collecting box 30 under the action of gravity, and part of the dust floats in the air during the cleaning process. Thus, the electrostatic adsorption module 60 can adsorb the dust floating in the air, so that the dust is collected in the dust collecting box 30, and the cleaning effect of the self-cleaning device on the filter screen 10 is improved.

The electrostatic adsorption module 60 can be powered on for use in a cleaning mode of the air conditioner, i.e., during the movement of the filter screen 10. Thus, the power can be saved.

Optionally, the electrostatic adsorption module 60 includes an electrostatic adsorption plate vertically inserted into the dust collecting box 30 and respectively located at two sides of the brush member 40 with the brush comb 50, so as to prevent interference of the rotation of the brush member 40 to the brush comb 50 for cleaning.

Alternatively, the electrostatic adsorption plate is disposed adjacent to the brush member 40. Thus, when the brush 40 cleans the filter screen 10, the electrostatic attraction plate can timely attract the fallen dust and lint.

Optionally, the self-cleaning device further comprises: the first driving device is disposed on the dust collecting box 30 or the frame 20, and connected to the brush member 40 for driving the brush member 40 to rotate and vibrate. The rotation and vibration of the brush member 40 are achieved by the first driving means, thereby achieving the cleaning effect and cleaning efficiency of the self-cleaning apparatus.

Optionally, the first driving means comprises a first motor 70, and the first motor 70 is provided on the dust box 30 or the frame 20. Wherein the first motor 70 is preferably provided in the dust box 30. So, the dismouting of being convenient for improves assembly efficiency. As shown in connection with fig. 7 and 8.

In the case where the first driving means drives the brush member 40 to rotate, the brush member 40 is brought into contact with the brush comb 50 to comb the lint.

The first driving device drives the brush element 40 to rotate, and the brush element 40 rotates to the brush comb 50 and contacts with the brush comb 50 to realize the purpose of combing the fallen batting.

After carding is finished, the first driving device drives the brush component 40 to rotate reversely, and the brush component 40 cleans the position of the filter screen 10.

In the case where the first driving means drives the brush member 40 to vibrate, the brush member 40 is brought into contact with the filter net 10 to sweep and vibrate the filter net 10, so that the dust on the filter net 10 falls.

At brush spare 40 to the in-process of clearing up filter screen 10, through the vibration of first drive arrangement drive brush spare 40 for brush spare 40 vibrates when clearing up filter screen 10, and transmits the vibration to filter screen 10, so, through the vibration, can accelerate dropping of dust at the in-process supplementary brush spare 40 of clearance.

In practical applications, the vibration of the brush member 40 is an optional mode, i.e. whether to start or not can be selected according to actual requirements, or the vibration mode can be started regularly according to a preset control logic. But it is not limited that the brush member 40 is always turned on in the vibration mode during operation.

For example, in the case that the first driving means drives the brush members 40 to rotate until the brush comb 50 falls off the batts, the brush members 40 may be controlled to be in a vibration state at this time. In this manner, the falling of the dust and the lint attached to the brush member 40 can be accelerated by the vibration.
