Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a dust removal component, a dust removal device and its control method, and an air conditioner. Background Technology

[0002] Air conditioner indoor units typically have a filter at the air inlet to prevent dust from entering the unit. However, during daily use, dust inevitably accumulates on the filter, clogging it. This not only affects the airflow, reduces cooling and heating performance, and increases energy consumption, but also breeds harmful microorganisms, polluting the air and endangering human health. Therefore, frequent filter cleaning is necessary, causing significant inconvenience for users.

[0003] To address the inconvenience of cleaning filters, most current solutions on the market use a combination of a roller and a brush to automatically clean the dust off flexible filters. However, in this cleaning method, the brush bristles come into direct contact with the filter, and the hard bristles can easily damage the filter, resulting in a fragile filter with a short lifespan. Summary of the Invention

[0004] This invention provides a dust removal component, a dust removal device and its control method, and an air conditioner, aiming to solve the problem that the brush bristles of existing dust removal devices easily damage the filter screen.

[0005] In a first aspect, embodiments of the present invention provide a dust removal assembly, including a substrate, an electrostatic electrode, bristles, a central shaft, and a driving member. The electrostatic electrode and the bristles are respectively disposed on opposite sides of the substrate. The bristles are retractable relative to the substrate to extend out of the substrate or be contained within the substrate. The central shaft is disposed on a side end of the substrate and connected to the driving member. The driving member is used to drive the substrate to rotate to flip the electrostatic electrode or the bristles.

[0006] Secondly, embodiments of the present invention provide a dust removal device, including: a dust collection box, a flexible baffle assembly, a filter screen, and a dust removal component as described above. The flexible baffle assembly and the filter screen are respectively disposed vertically at intervals within the dust collection box. The flexible baffle assembly can be rolled up or unfolded to open or close the dust collection box, and the dust removal component is movably disposed within the dust collection box. When the flexible baffle assembly is unfolded, bristles extend and face towards and abut against the flexible baffle assembly. When the dust removal component moves relative to the filter screen, an electrostatic electrode faces the filter screen and is energized.

[0007] In the dust removal device provided in the embodiments of the present invention, the dust removal box is provided with a first guide rail, a second guide rail and a movable guide rail assembly. The first guide rail and the second guide rail intersect, and the movable guide rail assembly is located at the intersection. The movable guide rail assembly is used to connect or disconnect the first guide rail and the second guide rail. The flexible baffle assembly slides along the first guide rail, and the dust removal assembly slides along the second guide rail.

[0008] In the dust removal device provided in the embodiments of the present invention, the movable guide rail assembly includes a third guide rail and a fourth guide rail. The intersection is provided with a first telescopic opening on both sides of the first guide rail, and the intersection is provided with a second telescopic opening on both sides of the second guide rail. The third guide rail can extend and retract relative to the first telescopic opening, and the fourth guide rail can extend and retract relative to the second telescopic opening.

[0009] Specifically, when the third guide rail extends into the first telescopic port and the fourth guide rail extends out of the second telescopic port, the second guide rail is connected; when the fourth guide rail extends into the second telescopic port and the third guide rail extends out of the first telescopic port, the first guide rail is connected.

[0010] In the dust removal device provided in the embodiments of the present invention, the second guide rail includes a vertical rail section and a horizontal rail section. One end of the vertical rail section intersects the first guide rail perpendicularly, and the other end of the vertical rail section is perpendicularly connected to the horizontal rail section. The horizontal rail section is arranged adjacent to the filter screen, and the horizontal rail section, the first guide rail, and the filter screen are parallel to each other.

[0011] In the dust removal device provided in the embodiments of the present invention, the vertical track section includes an extension section, which is formed by extending from the vertical intersection in a direction away from the filter screen.

[0012] In the dust removal device provided in the embodiments of the present invention, the dust removal box is provided with a dust collection trough, the dust collection trough is located below the vertical rail section, and the opening of the dust collection trough is provided with a horizontally movable cover plate.

[0013] Thirdly, embodiments of the present invention provide a control method for a dust removal device, the method comprising:

[0014] If the filter screen is detected to be clogged, the third guide rail is controlled to extend in and the fourth guide rail is extended to open the second guide rail.

[0015] The dust removal assembly is controlled to flip so that the electrostatic electrode faces the filter screen, and the dust removal assembly is controlled to move from the beginning of the vertical section of the second guide rail to the end of the horizontal section.

[0016] The electrostatic electrode is energized and the dust removal assembly is controlled to move from the end of the horizontal rail section to the connection point between the horizontal rail section and the vertical rail section.

[0017] Disconnect the power supply to the electrostatic electrode and control the dust removal assembly to return from the connection point between the horizontal and vertical rail sections to the beginning of the vertical rail section.

[0018] This invention provides a dust removal component, a dust removal device, a control method thereof, and an air conditioner. The dust removal device includes a dust collection box, a flexible baffle assembly, a filter screen, and a dust removal component. The dust removal component includes a base, electrostatic electrodes, brush bristles, a central shaft, and a driving component. The electrostatic electrodes and brush bristles are respectively disposed on both sides of the base. The driving component drives the base to rotate via the central shaft to flip the brush bristles or electrostatic electrodes. The flexible baffle assembly and the filter screen are respectively arranged vertically and at intervals in the dust collection box, and the dust removal component is movable within the dust collection box. When cleaning the flexible baffle assembly, the flexible baffle assembly is rolled up with the brush bristles facing down and the electrostatic electrodes facing up, and the dust on the flexible baffle assembly is cleaned by the brush bristles. When cleaning the filter screen, the driving component drives the base to rotate, causing the electrostatic electrodes to flip, with the electrostatic electrodes facing down and the brush bristles facing up. The electrostatic electrodes are energized, and the dust removal component moves along the filter screen, using the electrostatic charge generated by the electrostatic electrodes to adsorb the dust on the filter screen, thereby cleaning the filter screen. Thus, while cleaning the dust on the flexible baffle assembly, dust on the filter screen can also be adsorbed by electrostatic charge without contacting the filter screen, thereby avoiding damage to the filter screen.

[0043] To address the problem of brush bristles easily damaging the filter screen due to direct contact between the bristles and the filter screen, this invention proposes a dust removal component, a dust removal device and its control method, and an air conditioner. These components use electrostatic adsorption to remove dust, preventing direct contact with the filter screen and thus avoiding damage. The dust removal component of this invention is detailed below.

[0044] Reference Figures 1-13This invention provides a dust removal assembly 1, including a base 11, an electrostatic electrode 12, bristles 13, a central shaft 14, and a driving component. The electrostatic electrode 12 and the bristles 13 are respectively disposed on opposite sides of the base 11. The bristles 13 are retractable relative to the base 11 to extend outside the base 11 or be contained within the base 11. The central shaft 14 is disposed on the side end of the base 11 and connected to the driving component. The driving component is used to drive the base 11 to rotate to flip the electrostatic electrode 12 or the bristles 13.

[0045] Reference Figure 1 and Figure 2 Specifically, the integrated dust removal assembly 1 is a one-piece structure, with an overall elongated shape. Centered on the base 11, the electrostatic electrode 12 is located at the upper end of the base 11, and the brush bristles 13 are located at the lower end of the base 11. The brush bristles 13 are retractable, extending out of or retracting into the base 11. A central shaft 14 is located on the side face of the base 11. The driving component is a motor 33, which drives the base 11 to rotate via the central shaft 14, thereby achieving a 180° rotation of the electrostatic electrode 12 and the brush bristles 13. When the brush bristles 13 are needed for cleaning, the motor 33 drives the rotation, so that the brush bristles 13 are below and the electrostatic electrode 12 is above, using the brush bristles 13 to clean dust. When the electrostatic electrode 12 is needed for cleaning, the motor 33 drives the rotation, so that the electrostatic electrode 12 is below and the brush bristles 13 are above, or the brush bristles 13 are retracted into the base 11. The electrostatic electrode 12 is energized, generating static electricity, which attracts dust.

[0046] By implementing this embodiment, the dust on the filter screen 4 is adsorbed by the electrostatic charge generated by the electrostatic electrode 12, thereby cleaning the filter screen 4. This can replace the existing method of cleaning the filter screen 4 with the brush bristles 13. It does not require direct contact with the filter screen 4, thus avoiding damage to the filter screen. At the same time, the brush bristles 13 can be flipped so that they face downwards, and the dust on the flexible baffle 31 can be cleaned by the brush bristles 13.

[0047] Reference Figure 3 and Figure 4This invention also provides a dust removal device, including: a dust collection box 2, a flexible baffle assembly 31, a filter screen 4, and the aforementioned dust removal component 1. The flexible baffle assembly 31 and the filter screen 4 are respectively arranged vertically and at intervals within the dust collection box 2. The flexible baffle assembly 31 can be rolled up or unrolled to open or close the dust collection box 2, and the dust removal component 1 is movably disposed within the dust collection box 2. When the flexible baffle assembly 31 is unrolled, bristles 13 extend and face towards and abut against the flexible baffle assembly 31. When the dust removal component 1 moves relative to the filter screen 4, an electrostatic electrode 12 faces towards the filter screen 4 and is energized. The dust removal component 1 has been described in detail in the above embodiments, and for the sake of brevity, it will not be described again here.

[0048] Specifically, the dust collector 2 is generally rectangular in shape. The flexible baffle assembly 31 is positioned on the upper side of the dust collector 2, and the filter screen 4 is positioned on the lower side. The flexible baffle assembly 31 rolls up or unfolds along the short side of the dust collector 2. When the air conditioner is off, the flexible baffle assembly 31 is unfolded to prevent dust accumulation; when the air conditioner is on, the flexible baffle assembly 31 is rolled up, exposing the air conditioner's filter screen 4 and air inlet to allow airflow. The dust collector assembly 1 is positioned along the long side of the dust collector 2, with its two ends movably connected to the two sides of the short side of the dust collector 2, allowing it to move within the dust collector 2. It should be noted that when the air conditioner is off, the dust collector assembly 1 is in its default state, with one end of the electrostatic electrode 12 facing upwards and one end of the brush bristles 13 facing downwards, the brush bristles 13 being housed within the base 11.

[0049] In this embodiment, when the air conditioner is turned on, the flexible baffle 31 assembly 3 retracts, and the bristles 13 of the dust removal assembly 1 extend and contact the surface of the flexible baffle 31 assembly 3. As the flexible baffle 31 assembly 3 retracts, the bristles 13 sweep away the dust. Thus, the flexible baffle 31 assembly 3 can be cleaned every time the air conditioner is turned on. After the air conditioner has been used for a period of time, dust will accumulate on the filter screen 4. At this time, the dust removal assembly 1 can be flipped by the driving component so that the electrostatic electrode 12 faces downward and the bristles 13 retract into the base 11. Current is passed to the electrostatic electrode 12 to generate static electricity. Since the dust removal assembly 1 can move in the dust collection box 2, by moving the electrostatic electrode 12 along the filter screen 4, the generated static electricity can be used to adsorb the dust on the filter screen 4. The dust is cleaned by electrostatic adsorption, which avoids direct contact with the filter screen 4 and will not damage the filter screen 4.

[0050] Reference Figure 5In one embodiment, the dust collection box 2 is provided with a first guide rail 21, a second guide rail 22 and a movable guide rail assembly. The first guide rail 21 and the second guide rail 22 intersect, and the movable guide rail assembly is located at the intersection. The movable guide rail assembly is used to connect or disconnect the first guide rail 21 and the second guide rail 22. The flexible baffle 31 assembly 3 slides along the first guide rail 21, and the dust collection assembly 1 slides along the second guide rail 22.

[0051] In this embodiment, the first guide rail 21, the second guide rail 22, and the movable guide rail assembly are all disposed on the short side wall of the dust collector 2, and are symmetrically arranged on the short side wall of the dust collector 2. Both ends of the dust collector 1 are connected to the second guide rail 22 on the short side wall of the dust collector 2, allowing the dust collector 1 to move along the second guide rail 22. Both the first guide rail 21 and the second guide rail 22 extend along the short side of the dust collector 2, with the first guide rail 21 on the upper side of the short side wall of the dust collector 2 and the second guide rail 22 on the lower side of the short side wall of the dust collector 2. The first guide rail 21 is located on the upper side to allow the flexible baffle 31 of the flexible baffle assembly 31 to slide. The flexible baffle assembly 31 includes a drum 32, a motor 33, and the flexible baffle 31. The drum 32 and the motor 33 are located on the rear side of the dust collection box 2. The flexible baffle 31 can move forward along the first guide rail 21 to unfold, and it can also move backward along the first guide rail 21 to rewind onto the drum 32. The second guide rail 22 is located on the lower side to facilitate the movement of the dust collection assembly 1 to the lower part of the dust collection box 2 near the filter screen 4, allowing the dust collection assembly 1 to move along the second guide rail 22. During the movement, the electrostatic electrode 12 can adsorb the dust on the filter screen 4.

[0052] Continue to refer to Figure 4Since the dust removal component 1 needs to perform both cleaning of the flexible baffle 31 and cleaning of the filter screen 4, it must be able to move from above the flexible baffle 31 to above the filter screen 4. Therefore, the first guide rail 21 and the second guide rail 22 need to intersect, allowing the dust removal component 1 to continue moving above the filter screen 4 after cleaning the flexible baffle 31. Specifically, the second guide rail 22 is L-shaped, consisting of two sections: a vertical section 221 and a horizontal section 222. The vertical section 221 moves the dust removal component 1 from above the flexible baffle 31 to above the filter screen 4. Part of the vertical section 221 is located above the first guide rail 21, thus intersecting with it. A movable guide rail is provided at the intersection to ensure the normal sliding of the first guide rail 21 and the second guide rail 22. The horizontal rail section 222 is used to allow the dust removal assembly 1 to move along the filter screen 4 to electrostatically adsorb dust. Specifically, the movable guide rail can change the structure at the intersection. When it is necessary to ensure that the flexible baffle 31 slides normally in the first guide rail 21, the sliding guide rail can fill the intersection of the first guide rail 21, making the first guide rail 21 a complete guide rail and ensuring the normal sliding of the flexible baffle 31. When it is necessary to ensure that the dust removal assembly 1 moves from above the flexible baffle 31 to above the filter screen 4, the sliding guide rail can fill the intersection of the second guide rail 22, making the second guide rail 22 a complete guide rail and ensuring the normal sliding of the flexible baffle 31.

[0053] Reference Figure 4 and Figure 8 as well as Figure 11 In one embodiment, the movable guide rail assembly includes a third guide rail 23 and a fourth guide rail 24. The intersection is provided with first telescopic openings (not shown in the figure) on both sides of the first guide rail 21, and with second telescopic openings 241 on both sides of the intersection of the second guide rail 22. The third guide rail 23 is retractable relative to the first telescopic opening, and the fourth guide rail 24 is retractable relative to the second telescopic opening 241. When the third guide rail 23 extends into the first telescopic opening and the fourth guide rail 24 extends out of the second telescopic opening 241, the second guide rail 22 is open. When the fourth guide rail 24 extends into the second telescopic opening 241 and the third guide rail 23 extends out of the first telescopic opening, the first guide rail 21 is open.

[0054] Specifically, the movable guide rail assembly consists of two pairs of guide rail walls, namely the third guide rail 23 and the fourth guide rail 24, each with a pair of guide rail walls. Each pair of guide rail walls includes a left guide rail wall and a right guide rail wall. The short side walls on both sides of the dust collector 2 are provided with a first telescopic opening and a second telescopic opening 241. The first telescopic opening includes a first left telescopic opening and a first right telescopic opening; similarly, the second telescopic opening 241 includes a second left telescopic opening and a second right telescopic opening. The left and right guide rail walls of the third guide rail 23 are respectively located at the first left telescopic opening and the first right telescopic opening. The left and right guide rail walls of the fourth guide rail 24 are respectively located at the second left telescopic opening and the second right telescopic opening. Specifically, the first left telescopic opening and the first right telescopic opening are located on the left and right sides of the intersection, while the second left telescopic opening and the second right telescopic opening are located on the upper and lower sides of the intersection. When the left and right sides of the third guide rail 23 extend into the dust collector 2 through the first left and right telescopic openings, respectively, they fill the left and right sides of the intersection of the second guide rail 22, thus making the second guide rail 22 a complete guide rail. It should be noted that when the third guide rail 23 extends in, the fourth guide rail 24 extends out, meaning its two sides extend outside the dust collector 2 or are contained within the side wall of the dust collector 2. Similarly, when the left and right sides of the fourth guide rail 24 extend into the dust collector 2 through the second left and right telescopic openings, respectively, they fill the upper and lower sides of the intersection of the first guide rail 21, thus making the first guide rail 21 a complete guide rail. It should be noted that when the fourth guide rail 24 is inserted, the third guide rail 23 is extended, that is, the two guide rail walls of the third guide rail 23 extend out of the dust collection box 2, or are contained in the side wall of the dust collection box 2.

[0055] In this embodiment, the second guide rail 22 includes a vertical rail segment 221 and a horizontal rail segment 222. One end of the vertical rail segment 221 intersects the first guide rail 21 perpendicularly, and the other end of the vertical rail segment 221 is perpendicularly connected to the horizontal rail segment 222. The horizontal rail segment 222 is arranged adjacent to the filter screen 4, and the horizontal rail segment 222, the first guide rail 21, and the filter screen 4 are parallel to each other. Specifically, the second guide rail 22 is generally L-shaped. The vertical rail segment 221 is used to guide the dust removal assembly 1 from the upper side to the lower side of the dust collection box 2, and the horizontal rail segment 222 is positioned above the filter screen 4 and kept parallel to the filter screen 4. When the dust removal assembly 1 slides along the horizontal rail segment 222, the dust removal assembly 1 adsorbs dust on the filter screen 4 through the electrostatic electrode 12 while moving.

[0056] Reference Figure 6 and Figure 7Furthermore, the vertical rail section 221 includes an extension section, which extends from the vertical intersection in a direction away from the filter screen 4. Specifically, since the dust removal assembly 1 needs to be positioned above the flexible baffle 31 when cleaning the flexible baffle 31 assembly 3, the bristles 13 of the dust removal assembly 1 abut against the surface of the flexible baffle 31. As the flexible baffle 31 moves, the bristles 13 of the dust removal assembly 1 sweep away the dust above the flexible baffle 31. Therefore, the vertical rail section 221 needs to be extended to the top of the first guide rail 21. This part is the extension section, and the dust removal assembly 1 is positioned on this extension section when cleaning the flexible baffle 31. Specifically, the upper edge of the dust collection box 2 protrudes at the position corresponding to the vertical rail section 221, and this protruding part is used to set the extension section.

[0057] Reference Figure 9 In one embodiment, the dust collection box 2 is provided with a dust collection trough 25, which is located below the vertical rail section 221. A horizontally movable cover plate 26 is provided at the opening of the dust collection trough 25. Specifically, the dust collection trough 25 is located below the dust collection box 2, directly below the vertical rail section 221. Because the dust collection component 1 is located on the extension of the vertical rail section 221 when cleaning the flexible baffle 31, the bristles 13 of the dust collection component 1 extend and contact the flexible baffle 31. As the flexible baffle 31 retracts, the bristles 13 clean the dust on the flexible baffle 31 until it is retracted into the drum 32. At this point, the bristles 13 no longer contact the flexible baffle 31, and the dust on the flexible baffle 31 is swept by the bristles 13 into the dust collection trough 25 directly below, where it falls vertically. The dust collection device also includes a dust discharge pipe 5, through which the dust in the dust collection trough 25 is discharged. A cover plate 26 is provided above the opening of the dust collection trough 25. The cover plate 26 can move horizontally. When the cover plate 26 moves onto the opening, the dust collection trough 25 is closed. When the cover plate 26 moves away from the opening, the dust collection trough 25 is opened. Specifically, the cover plate 26 is opened when cleaning the flexible baffle 31 and the filter screen 4.

[0058] Reference Figure 14 This invention also provides a control method for a dust removal device. This control method is used to control the dust removal device described in the above embodiments. The dust removal device has been described in detail in the above embodiments, and for the sake of brevity, it will not be described again here. The control method for the dust removal device includes steps S1-S4.

[0059] S1. If filter screen 4 is detected to be clogged, control the third guide rail 23 to extend and the fourth guide rail 24 to extend to open the second guide rail 22.

[0060] S2. Control the dust removal component 1 to flip so that the electrostatic electrode 12 faces the filter screen 4, and control the dust removal component 1 to move from the beginning of the vertical rail section 221 of the second guide rail 22 to the end of the horizontal rail section 222.

[0061] S3. Power is supplied to the electrostatic electrode 12 and the dust removal assembly 1 is controlled to move from the end of the horizontal rail section 222 to the connection point between the horizontal rail section 222 and the vertical rail section 221;

[0062] S4. Disconnect the power supply to the electrostatic electrode 12 and control the dust removal assembly 1 to return from the connection point of the horizontal track section 222 and the vertical track section 221 to the beginning of the vertical track section 221.

[0063] Reference Figures 10-13 In this embodiment, to achieve electrostatic adsorption of dust on the filter screen 4, it is first necessary to detect whether the dust on the filter screen 4 has accumulated to a certain extent. Specifically, a sensor is used to detect whether the filter screen 4 is clogged. When the dust on the filter screen 4 accumulates to the point of clogging, the third guide rail 23 and the fourth guide rail 24 are controlled to move. The movement of the third guide rail 23 and the fourth guide rail 24 is controlled by the motor 33. Specifically, the third guide rail 23 is controlled to extend into the dust collection box 2 to fill the track wall of the second track, and the fourth guide rail 24 extends out, making the second guide rail 22 a complete track. However, the dust collection component 1 is controlled to flip by the drive unit, so that the electrostatic electrode 12 faces down and the bristles 13 face up, and the dust collection component 1 is controlled to move along the second guide rail 22. For ease of explanation, the starting position of the vertical rail segment 221 will be referred to as a (refer to...). Figure 10 The connection point between vertical track segment 221 and horizontal track segment 222 is b (refer to...). Figure 12 The end position of horizontal track segment 222 is c. (Refer to...) Figure 13 The dust removal assembly 1 moves in the sequence abc on the second guide rail 22. Upon reaching position c, it begins to supply electricity to the electrostatic electrode 12, causing it to generate static electricity. This drives the dust removal assembly 1 from c back to b. During this process, the electrostatic electrode 12 retains static electricity, allowing it to attract dust from the filter screen 4, thus cleaning the filter screen 4. Upon returning to position b, the power supply to the electrostatic electrode 12 is disconnected, preventing it from generating static electricity and losing its adsorption force. The dust falls into the dust collection trough 25 under gravity. Finally, the dust removal assembly 1 is controlled to return from b to a, completing the cleaning of the filter screen 4.

[0064] Reference Figure 15 In one embodiment, before step S1, steps S01-S02 are also included.

[0065] S01. If an air conditioner start command is detected, control the flexible baffle 31 assembly 3 to roll up and control the cover plate 26 on the dust collection tank 25 to open and control the brush of the dust removal assembly 1 to extend.

[0066] S02. After the flexible baffle 31 component 3 is fully rolled up, control the brush of the dust removal component 1 to retract.

[0067] In this embodiment, the dust removal component 1 can clean the dust on the flexible baffle 31 each time the air conditioner is turned on. Specifically, upon receiving the air conditioner's turn-on command, such as a user's turn-on command via remote control, the cover 26 on the dust collection trough 25 is first opened to expose the dust collection trough 25. Then, the dust removal component 1 extends the brush bristles 13 so that they contact the upper surface of the flexible baffle 31. Then, the motor 33 drives the drum 32 to rotate, causing the flexible baffle 31 to rewind. The flexible baffle 31 moves along the first guide rail 21. As the flexible baffle 31 moves, the brush sweeps the dust on the flexible baffle 31 until the flexible baffle 31 component 3 is rewound into the drum 32. Under the action of gravity, the dust falls into the dust collection trough 25. Finally, the brush bristles 13 are retracted back into the base 11, completing the cleaning of the flexible baffle 31.

[0068] This invention also provides an air conditioner including the aforementioned dust removal device, which is used to execute the aforementioned control method. The dust removal device and its control method have been described in detail in the above embodiments, and for the sake of brevity, will not be repeated here.

[0069] Specifically, refer to Figure 16 The following section explains the control process of the dust removal device by using the control logic of the air conditioner.

[0070] When the air conditioner is off, the dust removal component 1 is in its default state, and both the third guide rail 23 and the fourth guide rail 24 are closed. Figure 4 As shown. When the air conditioner is turned on, the third guide rail 23 opens (extends), the fourth guide rail 24 closes (extends), the dust removal component 1 brush extends, the lower cover 26 opens, the drive component motor 33 drives the drum 32 to rotate and open the flexible baffle 31. The brush sweeps the dust accumulated on the baffle into the dust collection trough 25 below. After the flexible baffle 31 is fully opened, the brush retracts. Figure 6 and 7 As shown.

[0071] like Figure 10 and 12As shown in Figure 13, when the detection device detects that the air conditioner filter 4 is clogged, the third guide rail 23 closes (extends), the fourth guide rail 24 opens (extends), and the dust removal assembly 1 rotates to position b with the electrostatic electrode 12 at the bottom and the brush end at the top, moving vertically along the second guide rail 22. Then it moves horizontally along the second guide rail 22 to position c, at which point the electrostatic electrode 12 is energized. The dust removal assembly 1 is controlled to slowly move towards position b, and the electrostatic electrode 12 can adsorb the dust on the lower filter 4 along the moving path of the dust removal assembly 1. When it reaches position b, the electrostatic electrode 12 is de-energized, releasing the adsorbed dust, which falls into the lower dust collection trough 25. When the filter 4 is cleaned, the dust collection box cover 26 closes, discharging the dust and other debris from the dust collection box. The dust removal device moves along the second guide rail 22 to position a, rotates to position a with the brush end at the bottom and the electrostatic electrode 12 at the top, the third guide rail 23 opens (extends), and the fourth guide rail 24 closes (extends).

[0072] When the air conditioner is turned off, the drive assembly closes the flexible baffle 31 along the first guide rail 21, sealing the top of the air conditioner and preventing dust from falling into the air conditioner.

[0073] This embodiment solves the problem of dust accumulation on the filter 4 due to prolonged use of the indoor unit of the air conditioner, which affects the performance of the air conditioner and the health of the user; it also solves the problem of the air conditioner filter 4 needing frequent disassembly and cleaning due to dirt and clogging, which is inconvenient; it solves the problem of the filter 4 being easily damaged when cleaned with a brush; it can achieve dust prevention and dust removal effects, and the flexible baffle 31 can be cleaned every time the air conditioner is turned on; it eliminates the need for the user to manually disassemble and clean the filter 4, and the dust removal component 1 will not damage the filter 4, thus ensuring the performance of the air conditioner.

[0074] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
