Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] As part of the air conditioning system, the indoor unit of an air conditioner is installed indoors and used to exchange heat with indoor air, thereby raising or lowering the indoor temperature.

[0003] An air conditioner indoor unit has an air inlet and an air outlet. The air inlet is equipped with a filter to filter the air entering the unit, preventing dust and other debris from entering. After a period of use, excessive dust and debris accumulate on the filter, causing some of the filter pores to become clogged, reducing airflow and affecting the air conditioner's cooling or heating efficiency. Currently, to maintain efficient operation, air conditioner indoor units are equipped with a roller brush. This brush removes debris from the filter and places it in a dust collection box, which is then cleaned regularly.

[0004] After the indoor unit of an air conditioner has been running for a period of time, there is a need to completely disassemble the filter assembly to thoroughly clean the filter screen and roller brush in the filter assembly. During the disassembly process, since the drive motor used to drive the filter screen to move relative to the roller brush is usually connected to the filter screen, it is often necessary to remove the drive motor from the casing before the filter assembly can be disassembled. However, as a live part, the drive motor is generally required to be kept out of reach of the user to avoid safety accidents. Summary of the Invention

[0005] The purpose of this invention is to provide an air conditioner indoor unit that allows users to disassemble the filter assembly for thorough cleaning without touching the drive motor.

[0006] To achieve the above objectives, the present invention provides an indoor air conditioning unit, comprising:

[0007] The casing has an air inlet on the top side and a through hole on the front side;

[0008] A filter assembly is detachably installed inside the housing. The filter assembly includes a base, a self-cleaning component, and a filter screen. The base is detachably connected to the housing. The self-cleaning component and the filter screen are both installed on the base, and the filter screen covers the air inlet.

[0009] A transmission mechanism, mounted on the base, is connected to the filter screen; and

[0010] A drive motor is mounted on the housing, and the power output end of the drive motor is detachably connected to the transmission mechanism.

[0011] The filter assembly and the transmission mechanism can be detached from the housing through the through hole. The drive motor can drive the filter screen to move along a predetermined trajectory so that different areas of the filter screen are positioned opposite to the self-cleaning component. The self-cleaning component can clean the filter screen area opposite to it.

[0012] In some embodiments, the filtering component further includes:

[0013] A first reel, extending laterally and rotatably mounted on the base; and

[0014] The second reel extends to the left and right and is rotatably mounted on the base, and the second reel is spaced apart from the first reel;

[0015] One end of the filter screen is connected to the first roller and the other end is connected to the second roller. The filter screen is tensioned between the first roller and the second roller. The transmission mechanism is connected to the first roller and the second roller respectively. The rotation of the drive motor can drive the first roller and the second roller to rotate, so as to tension the filter screen.

[0016] In some embodiments, a mounting groove is provided on the front side of the housing, and the base includes:

[0017] The mounting part is disposed within the mounting groove and has a mounting chamber. The self-cleaning component, the first reel, and the second reel are all disposed within the mounting chamber. The transmission mechanism is mounted on the outside of the mounting part.

[0018] The bracket extends in a front-to-back direction, the front side of the bracket is connected to the mounting part, the bracket passes through the through hole, and the filter screen is wound around the outer periphery of the bracket;

[0019] The drive motor can rotate to drive the first and second reels to rotate in opposite directions.

[0020] In some embodiments, the power output end of the drive motor is provided with a drive gear, and the transmission mechanism includes:

[0021] A first driven gear, mounted at one end of the first reel, meshes with the drive gear; and

[0022] The second driven gear is mounted on one end of the second spool and meshes with the first driven gear.

[0023] In some embodiments, a receiving cavity is provided on the outer side of the mounting portion, and both the first driven gear and the second driven gear are installed in the receiving cavity.

[0024] In some embodiments, the self-cleaning component includes a roller brush capable of brushing away debris adhering to the filter screen, and a slot is also provided on the front side of the housing;

[0025] The filtering component also includes:

[0026] A dust collection box is installed on the base and below the roller brush to collect the debris brushed off the filter screen. The bottom of the dust collection box has a dust discharge port.

[0027] A dust collection box is inserted into the slot and positioned below the dust collection box. The top of the dust collection box is open and connected to the dust collection port.

[0028] A lever, which slides inside the dust collection box and can sweep debris from the dust collection box to the dust outlet.

[0029] In some embodiments, the transmission mechanism is also connected to the roller brush, and a drive gear is provided on the power output end of the drive motor. The transmission mechanism includes:

[0030] The third driven gear is mounted on one end of the roller brush and is connected to the drive gear.

[0031] In some implementations, it also includes:

[0032] A sliding seat, wherein the sliding seat is slidably disposed within the dust collection box and is capable of sliding and switching between a first position and a second position, which are spaced apart to the left and right; and

[0033] A grip base, which is slidably disposed on the front side of the dust collection box and has a rotating part that is rotatably connected to the lever;

[0034] The paddle is rotatably connected to the sliding seat and can rotate between a first angle and a second angle around a pivot extending forward and backward. When the paddle is at the first angle, it is laterally blocked inside the dust collection box and abuts against the bottom wall of the dust collection box. When the paddle is at the second angle, it retracts upward to avoid the bottom space of the dust collection box. The grip can slide to drive the paddle to rotate to the first angle or the second angle.

[0035] In some embodiments, the roller brush has a first brush for brushing debris adhering to the filter screen into the dust collection box;

[0036] The indoor unit of the air conditioner also includes:

[0037] A cleaning brush, which is disposed in the dust collection box and is used to brush away debris attached to the roller brush into the dust collection box, the cleaning brush having a second brush inserted into the roller brush.

[0038] In some embodiments, the filter includes a filtering area and a blocking area connected in sequence. The filtering area is used to filter air entering from the air inlet, and the blocking area is used to block air entering from the air inlet from entering the housing. The filter can move between a filtering position and a blocking position as it moves along a predetermined trajectory. When the filter is in the filtering position, the filtering area covers the air inlet; when the filter is in the blocking position, the blocking area covers the air inlet.

[0039] Compared with the prior art, the beneficial effects of the air conditioner indoor unit of this invention are as follows:

[0040] The air conditioner indoor unit provided by this invention, after working for a period of time, accumulates a lot of debris on the filter screen. At this time, the air conditioner indoor unit enters a self-cleaning process. During this process, the self-cleaning component and the filter screen move relative to each other, with different areas of the self-cleaning component and the filter screen positioned opposite each other, and cleaning the filter screen area opposite to it. When, after a period of use, there is a lot of debris attached to the filter screen and it is difficult for the self-cleaning component to clean it, the base and the casing are disassembled, so that the filter screen and the self-cleaning component installed on the base are removed from the casing along with the base. Then, the user can thoroughly clean the disassembled filter components. During this process, since the transmission mechanism is connected to the filter screen, the transmission mechanism can be disassembled from the casing along with the filter screen. The power output end of the drive motor is detachably connected to the transmission mechanism. Before disassembling the base from the casing, the connection between the power output end of the drive motor and the transmission mechanism can be disconnected, so that when the transmission mechanism is disassembled from the casing along with the filter screen, the drive motor will not be disassembled with the transmission mechanism.

[0041] Based on the above working process, users can disassemble and thoroughly clean the filter assembly without touching the drive motor, and the drive motor, which serves as a jump-start component, will not cause any safety accidents during this process. Furthermore, the drive motor, as a jump-start component, can be installed and concealed within the housing, providing excellent protection against damage from external forces.

[0078] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0079] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0081] In the air conditioning industry, the indoor unit of an air conditioner has a built-in heat exchanger. It is placed indoors and heats or cools the indoor air through the built-in heat exchanger to achieve the effect of heating or cooling. It generally includes a casing 100, a heat exchanger located inside the casing 100 and connected to the outdoor unit of the air conditioner, and a fan for drawing in and pumping out indoor air. When working, the fan rotates and draws indoor air in through the air inlet 110 on the casing 100. After the air exchanges heat with the heat exchanger, it is pumped out through the air outlet on the casing 100.

[0082] like Figures 1 to 22 As shown, an indoor air conditioning unit according to an embodiment of the present invention includes a housing 100, a filter assembly 200, a transmission mechanism 500, and a drive motor 400. The housing 100 has an air inlet 110 on its top side and a through hole 120 on its front side. The filter assembly 200 is detachably installed inside the housing 100 and includes a base 210, a self-cleaning component 220, and a filter screen 230. The base 210 is detachably connected to the housing 100, and both the self-cleaning component 220 and the filter screen 230 are installed on the base 210, with the filter screen 230 covering the air inlet 110. The transmission mechanism... The filter assembly 200 is mounted on the base 210, and the transmission mechanism 500 is connected to the filter screen 230. The drive motor 400 is mounted on the housing 100, and the power output end of the drive motor 400 is detachably connected to the transmission mechanism 500. The filter assembly 200 and the transmission mechanism 500 can be removed from the housing 100 through the through hole 120. The drive motor 400 can drive the filter screen 230 to move along a predetermined trajectory so that different areas of the filter screen 230 are positioned opposite to the self-cleaning component 220. The self-cleaning component 220 can clean the areas of the filter screen 230 opposite to it.

[0083] In this embodiment, after the air conditioner indoor unit has been operating for a period of time, a large amount of debris accumulates on the filter 230. At this point, the air conditioner indoor unit enters a self-cleaning process. During this process, the self-cleaning component 220 and the filter 230 move relative to each other, with different areas of the self-cleaning component 220 and the filter 230 positioned opposite each other, and the self-cleaning component 220 cleans the areas of the filter 230 opposite to it. When, after a period of use, a large amount of debris accumulates on the filter 230 and is difficult for the self-cleaning component 220 to clean, the base 210 is disassembled from the housing 100, so that the filter 230 and the self-cleaning component 220 installed on the base 210 are removed from the housing 100 along with the base 210. The filter assembly 200 can be disassembled from the housing 100. The user can then thoroughly clean the disassembled filter assembly 200. During this process, since the transmission mechanism 500 is connected to the filter screen 230, the transmission mechanism 500 can be disassembled from the housing 100 along with the filter screen 230. The power output end of the drive motor 400 is detachably connected to the transmission mechanism 500. Before disassembling the base 210 from the housing 100, the connection between the power output end of the drive motor 400 and the transmission mechanism 500 can be disconnected, so that when the transmission mechanism 500 is disassembled from the housing 100 along with the filter screen 230, the drive motor 400 will not be disassembled along with the transmission mechanism 500.

[0084] Based on the above working process, users can disassemble the filter assembly 200 and thoroughly clean it without touching the drive motor 400. During this process, the drive motor 400, as a jump-start component, will not cause any safety accidents. At the same time, the drive motor 400, as a jump-start component, can be installed and hidden inside the housing 100, and is well protected from damage by external forces.

[0085] In some implementations, please refer to Figure 6 , Figure 8 as well as Figure 9 The filter assembly 200 also includes a first roller 240 and a second roller 250; the first roller 240 extends left and right and is rotatably mounted on the base 210; the second roller 250 extends left and right and is rotatably mounted on the base 210, and the second roller 250 is spaced apart from the first roller 240; wherein, one end of the filter screen 230 is connected to the first roller 240 and the other end is connected to the second roller 250, the filter screen 230 is tensioned between the first roller 240 and the second roller 250, the transmission mechanism 500 is connected to the first roller 240 and the second roller 250 respectively, and the drive motor 400 can rotate to drive the first roller 240 and the second roller 250 to rotate, so as to tension the filter screen 230. In this embodiment, the drive motor 400 drives the first roller 240 and the second roller 250 to rotate through the transmission mechanism 500, so that the filter screen 230 moves relative to the self-cleaning member 220 by winding and unwinding on the first roller 240 and the second roller 250, which can ensure that the filter screen 230 is always taut and moves smoothly relative to the self-cleaning member 220.

[0086] Alternatively, in some implementations, please refer to Figure 6 , Figure 8 as well as Figure 9 The first reel 240 includes a detachably connected first part 241 and a second part 242, and the second reel 250 includes a detachably connected third part 251 and a fourth part 252. One end of the filter screen 230 is clamped between the first part 241 and the second part 242, and the other end of the filter screen 230 is clamped between the third part 251 and the fourth part 252. In this embodiment, by setting both the first reel 240 and the second reel 250 as two-part structures, and by clamping, the two ends of the filter screen 230 are fixed to the first reel 240 and the second reel 250, so as to ensure that the filter screen 230 can be stably connected to the first reel 240 and the second reel 250 respectively.

[0087] Alternatively, in some implementations, please refer to Figure 6 , Figure 8 as well as Figure 9 The first part 241, the second part 242, the third part 251, and the fourth part 252 are all strip structures that extend in the left-right direction and have an arc-shaped cross-section. In this embodiment, the outer surfaces of the first part 241, the second part 242, the third part 251, and the fourth part 252 are smooth, which facilitates the winding and unwinding of the filter screen 230 on the first roll 240 and the second roll 250.

[0088] Alternatively, in some implementations, please refer to Figure 6 , Figure 8 as well as Figure 9 The first part 241 has a first seat 243 on its inner side, and the second part 242 has a second seat 244 on its inner side. The first seat 243 and the second seat 244 are snap-fitted together to allow the first part 241 and the second part 242 to be detachably connected. The third part 251 has a third seat 253 on its inner side, and the fourth part 252 has a fourth seat 254 on its inner side. The third seat 253 and the fourth seat 254 are snap-fitted together to allow the third part 251 and the fourth part 252 to be detachably connected. In this embodiment, the first part 241 and the second part 242 are connected by snap-fitting, and the third part 251 and the fourth part 252 are also connected by snap-fitting, which facilitates disassembly to remove the filter screen 230 for thorough cleaning.

[0089] In some implementations, please refer to Figure 2 , Figure 6 , Figure 7 , Figure 8 as well as Figure 17The front side of the housing 100 is provided with a mounting groove 130. The base 210 includes a mounting part 211 and a bracket 212. The mounting part 211 is located in the mounting groove 130 and has a mounting chamber 213. The self-cleaning component 220, the first roller 240 and the second roller 250 are all located in the mounting chamber 213. The transmission mechanism 500 is installed on the outside of the mounting part 211. The bracket 212 extends in the front-rear direction and is connected to the mounting part 211 at its front. The bracket 212 passes through the through hole 120 and the filter screen 230 is wound around the outer periphery of the bracket 212. The drive motor 400 can rotate to drive the first roller 240 and the second roller 250 to rotate in opposite directions. In this embodiment, the mounting part 211 is disposed within the mounting groove 130, and the bracket 212 extends rearward through the through hole 120. When disassembling the filter assembly 200, since the mounting part 211, which integrates the first roller 240, the second roller 250, and the self-cleaning component 220, is located within the mounting groove 130, the user can directly remove the mounting part 211 from the mounting groove 130. The bracket 212 and the filter screen 230 will then pass through the through hole 120 and detach from the housing 100 as the mounting part 211 is removed. Similarly, When installing the filter assembly 200, the user can directly install the mounting part 211 into the mounting slot 130. The bracket 212 and the filter screen 230 will pass through the through hole 120 and be placed inside the housing 100 as the mounting part 211 is installed. Thus, in this embodiment, the first roller 240, the second roller 250 and the self-cleaning member 220 are integrated on the mounting part 211, and the mounting part 211 is installed on the mounting slot 130 on the front side of the housing 100, making it more convenient to remove and install the filter assembly 200.

[0090] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 15 , Figure 16 , Figure 18 as well as Figure 19The drive motor 400 has a drive gear 410 at its power output end, and the transmission mechanism 500 includes a first driven gear 510 and a second driven gear 520. The first driven gear 510 is installed at one end of the first reel 240 and meshes with the drive gear 410. The second driven gear 520 is installed at one end of the second reel 250 and meshes with the first driven gear 510. In this embodiment, during the self-cleaning process, the drive motor 400 operates, driving the first driven gear 510 to rotate via the drive gear 410 on the power output end, which in turn drives the first roller 240 to rotate. At the same time, the first driven gear 510 also drives the second driven gear 520 meshing with it to rotate, which in turn drives the second roller 250 to rotate. Thus, under the action of the first roller 240 and the second roller 250, the filter screen 230, which is tensioned between the first roller 240 and the second roller 250, moves along a predetermined trajectory, so that different areas on the filter screen 230 are sequentially opposite to the self-cleaning member 220, and the self-cleaning member 220 cleans the filter screen 230 in different areas.

[0091] In some implementations, please refer to Figure 15 , Figure 16 as well as Figure 17 The mounting part 211 has a receiving cavity 214 on its outer side, and the first driven gear 510 and the second driven gear 520 are both installed in the receiving cavity 214. In this embodiment, the receiving cavity 214 provides good protection and concealment for the first driven gear 510, the second driven gear 520, the intermediate gear 540, and the third driven gear 530, facilitating wiring and preventing the moving parts from damaging other parts.

[0092] Alternatively, in some implementations, please refer to Figure 18 and Figure 19 The first driven gear 510 has a first prism 511 in the middle, and the end of the first roller 240 has a first hole adapted to the first prism 511. The first prism 511 passes through the mounting part 211 and is inserted into the first hole. The second driven gear 520 has a second prism 521 in the middle, and the end of the second roller 250 has a second hole adapted to the second prism 521. The second prism 521 passes through the mounting part 211 and is inserted into the second hole. The third driven gear 530 has a third prism 531 in the middle, and the end of the roller brush has a third hole adapted to the third prism 531. The third prism 531 passes through the mounting part 211 and is inserted into the third hole. In this embodiment, by setting the first prism 511, the first hole, the second prism 521, the second hole, the third prism 531, and the third hole, the first driven gear 510, the second driven gear 520, and the third driven gear 530 are respectively connected to the first roller 240, the second roller 250, and the roller brush, resulting in a stable transmission effect.

[0093] Alternatively, in some implementations, please refer to Figure 1 , Figure 2 , Figure 10 , Figure 15 as well as Figure 20 The number of air inlets 110 and filter components 200 are multiple and correspond one-to-one, so as to increase the air intake and air output of the indoor unit of the air conditioner in this embodiment, thereby improving the cooling or heating effect.

[0094] Optionally, in one embodiment, there are multiple drive motors 400 and transmission mechanisms 500, and each drive motor 400 is connected to the filter assembly 200 through a corresponding transmission mechanism 500, so that each filter assembly 200 can be driven individually to perform a self-cleaning process. Optionally, in another embodiment, as... Figure 18 and Figure 19 As shown, it also includes at least one connecting rod 550 and multiple transmission mechanisms 500. The multiple transmission mechanisms 500 are connected to each other through the connecting rod 550. The power output end of the drive motor 400 is connected to the connecting rod 550. The drive motor 400 can drive multiple filter components 200 to work simultaneously through the connecting rod 550 and the multiple transmission mechanisms 500, which simplifies the complexity of the drive structure of the air conditioner indoor unit.

[0095] Alternatively, in some implementations, please refer to Figure 17 A notch 215 is provided on the side wall of the accommodating cavity 214. A portion of the first driven gear 510 extends out from the notch 215, and the driving gear 410 meshes with the first driven gear 510 extending from the notch 215. In this embodiment, the meshing of the driving gear 410 and the first driven gear 510 is achieved by the notch 215. The detachable connection between the transmission mechanism 500 and the drive motor 400 is achieved through the meshing between the first driven gear 510 and the driving gear 410. When disassembling, the first driven gear 510 is disassembled along with the mounting part 211, while the driving gear 410 is not affected.

[0096] Optionally, in some embodiments, the first driven gear 510 and the second driven gear 520 have the same number of teeth to ensure that the rotational speeds of the first roller 240 and the second roller 250 are the same, and the filter screen 230 is always tensioned on the first roller 240 and the second roller 250.

[0097] In some implementations, please refer to Figure 10The indoor unit of the air conditioner also includes a limiting block 160. The limiting block 160 is rotatably mounted on the front side of the housing 100 and located on the edge of the mounting groove 130. The limiting block 160 can rotate between a locked position and an unlocked position. When the limiting block 160 is in the locked position, it is at least partially located on the front side of the mounting part 211 to prevent the mounting part 211 from sliding out of the mounting groove 130. When the limiting block 160 is in the unlocked position, it is located on the outer edge of the mounting groove 130 so that the mounting part 211 can slide forward and disengage from the mounting groove 130. In this embodiment, during normal operation, the limiting block 160 is in the locked position, which effectively prevents the mounting part 211 from sliding out of the mounting groove 130. When it is necessary to remove the mounting part 211, the limiting block 160 can be rotated to the unlocked position, making the operation convenient.

[0098] Preferably, there are multiple limiting blocks 160.

[0099] In some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 20 as well as Figure 21 The self-cleaning component 220 includes a roller brush capable of brushing away debris adhering to the filter screen 230; the filter assembly 200 also includes a dust collection box 600, which is mounted on the base 210 and located below the roller brush to collect the debris brushed off the filter screen 230. In this embodiment, the roller brush is used to brush away debris adhering to the filter screen 230 and collect it in the dust collection box 600.

[0100] Alternatively, in some implementations, please refer to Figures 10 to 14The dust collection box 600 has a dust collection port 620 at its bottom, and also includes a dust collection box 700 and a brush 610. A slot 150 is also provided on the front side of the housing 100, into which the dust collection box 700 is inserted, positioned below the dust collection box 600. The top of the dust collection box 700 is open and connected to the dust collection port 620. The brush 610 slides within the dust collection box 600 and can sweep debris from the dust collection box 600 to the dust collection port 620. Thus, the roller brush cleans the filter screen 230, removing debris adhering to the filter screen 230 into the dust collection box 600 below. Specifically, the filter screen 230 can move relative to the roller brush, allowing the roller brush to sequentially contact each area of ​​the filter screen 230 and remove debris adhering to each area. After a period of use, the user can move the drive lever 610 within the dust collection box 600 to sweep debris from the dust collection box 600 to the dust collection port 620. The debris then falls from the dust collection port 620 and collects in the dust collection box 700. The user can then remove the dust collection box 700 from the slot 150 and clean it, thus completing the cleaning and maintenance of the indoor air conditioner unit. Based on the above process, during cleaning and maintenance, the user only needs to use the drive lever 610 to collect the debris in the dust collection box 700, remove the dust collection box 700 from the slot 150, and clean it. Disassembly and cleaning are simple and quick, facilitating the cleaning and maintenance of the indoor air conditioner unit.

[0101] Alternatively, in some implementations, please refer to Figure 2 , Figure 3 , Figures 10 to 14 The slot 150 has a first sidewall 151 and a second sidewall 152 spaced apart in the left-right direction. A first slot 153 is formed on the first sidewall 151, and a second slot 154 is formed on the second sidewall 152. The dust collection box 700 has a first locking block 710 and a second locking block 720 spaced apart in the left-right direction. The first locking block 710 is inserted into the first slot 153, and the second locking block 720 is inserted into the second slot 154. In this embodiment, the dust collection box 700 is detachably installed in the slot 150 by the cooperation of the first locking block 710 and the first slot 153, and the cooperation of the second locking block 720 and the second slot 154. When disassembling, the first locking block 710 is driven away from the first sidewall 151, and the second locking block 720 is driven away from the second sidewall 152, which can achieve disassembly. The operation is convenient.

[0102] Alternatively, in some implementations, please refer to Figures 10 to 14It also includes a sliding seat 900 and a grip seat 800; the sliding seat 900 is slidably disposed within the dust collection box 600 and can slide and switch between a first position and a second position that are spaced apart to the left and right; the grip seat 800 is slidably disposed on the front side of the dust collection box 600 and has a connecting part that is rotatably connected to a paddle 610; wherein, the paddle 610 is rotatably connected to the sliding seat 900 and can rotate and switch between a first angle and a second angle around a pivot extending forward and backward; when the paddle 610 is at the first angle, the paddle 610 is laterally blocked within the dust collection box 600 and abuts against the bottom wall of the dust collection box 600; when the paddle 610 is at the second angle, the paddle 610 is retracted upward to avoid the bottom space of the dust collection box 600; the grip seat 800 can slide to drive the paddle 610 to rotate to the first angle or the second angle. In this embodiment, when it is necessary to concentrate the debris in the dust collection box 600, the grip 800 drives the paddle 610 to rotate to a first angle, and the paddle 610 drives the sliding seat 900 to slide from the first position to the second position. The paddle 610, which is laterally blocking the dust collection box 600, sweeps and concentrates the debris in the dust collection box 600 to the second position. Then, the grip drives the paddle 610 to rotate to the second angle, and the paddle 610 drives the sliding seat 900 to slide from the second position to the first position. At this time, the paddle 610 retracts upward, and the debris at the bottom of the dust collection box 600 will not be brought back to the first position. By repeatedly driving the paddle 610 to move, the debris in the dust collection box 600 is concentrated to the second position. When cleaning, the dust collection box 600 is taken out and the debris concentrated in the second position is cleaned. Therefore, the dust collection box 600 can be concentrated in one place by the setting of the grip 800, the lever 610 and the sliding seat 900, which facilitates the subsequent cleaning of the dust collection box 600 and makes the cleaning and maintenance of the air conditioner indoor unit convenient.

[0103] Alternatively, in some implementations, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 20 as well as Figure 21The system also includes a cleaning brush 260. The roller brush has a first brush 221 for brushing away debris attached to the filter screen 230 into the dust collection box 600. The cleaning brush 260 is disposed in the dust collection box 600 and is used to brush away debris attached to the roller brush into the dust collection box 600. The cleaning brush 260 has a second brush 261 inserted into the roller brush. In this embodiment, during self-cleaning, some debris will adhere to the first brush 221 of the roller brush. At this time, under the action of the second brush 261 of the cleaning brush 260, the debris attached to the first brush 221 will be brushed away into the dust collection box 600. Thus, the first brush 221 can contact and clean the filter screen 230 without debris attached to it. Based on the above working process, under the action of the roller brush and the cleaning brush 260, after the roller brush removes the debris from the filter screen 230, the debris attached to the roller brush can be brushed away by the cleaning brush 260 into the dust collection box 600. That is, the debris attached to the roller brush will not return to the filter screen 230, thus ensuring the self-cleaning effect of the filter screen 230.

[0104] In some implementations, please refer to Figures 5 to 8 as well as Figures 15 to 21 The transmission mechanism 500 is also connected to the roller brush. A drive gear 410 is provided on the power output end of the drive motor 400. The transmission mechanism 500 includes a third driven gear 530, which is mounted on one end of the roller brush and connected to the drive gear 410. In this embodiment, the intermediate gear 540 and the third driven gear 530 enable the drive motor 400 to simultaneously drive the roller brush to rotate in the opposite direction to the filter screen 230, achieving a good brushing effect on the filter screen 230 and further simplifying the drive structure of the air conditioner indoor unit.

[0105] In some implementations, please refer to Figures 1 to 6 It also includes a panel 300; the panel 300 is detachably connected to the front side of the housing 100 to block the through hole 120. In this embodiment, when the indoor unit of the air conditioner is in normal use, the panel 300 covers the front side of the housing 100 to make the appearance of the indoor unit of the air conditioner harmonious; when it is necessary to disassemble and clean the filter assembly 200, the panel 300 must first be removed from the front side of the housing 100, and then the filter assembly 200 can be removed from the housing 100 through the through hole 120.

[0106] Alternatively, in some implementations, please refer to 1 to Figure 6 A first mating part 310 is provided on the inner side of the panel 300, and a second mating part 140 is provided on the front side of the housing 100. The first mating part 310 and the second mating part 140 are connected by a snap-fit, so that the panel 300 can be detachably connected to the front side of the housing 100. In this embodiment, the connection between the panel 300 and the housing 100 is achieved by a snap-fit, which facilitates the disassembly and installation of the panel 300.

[0107] Alternatively, in some implementations, please refer to Figure 22 The filter 230 includes a filtering area 231 and a blocking area 232 connected in sequence. The filtering area 231 filters the air entering from the air inlet 110, and the blocking area 232 prevents the air entering from the air inlet 110 from entering the housing 100. When the filter 230 moves along a predetermined trajectory, it can move between a filtering position and a blocking position. When the filter 230 is in the filtering position, the filtering area 231 covers the air inlet 110; when the filter 230 is in the blocking position, the blocking area 232 covers the air inlet 110. In this embodiment, when the indoor unit of the air conditioner is working normally, the filter 230 is in the filtering position, the filtering area 231 covers the air inlet 110 and performs normal filtering function; when the indoor unit of the air conditioner is stopped, the filter 230 moves from the filtering position to the blocking position, the blocking area 232 covers the air inlet 110, and air and dust are blocked by the blocking area 232, preventing dust from entering the housing 100. It is understood that the filter area 231 is an area with multiple small-diameter through holes. Air can enter the casing through these holes, but large particles of dust and other debris in the air cannot pass through, thus performing the function of conventional air filtration. The sealing area 232 is an area without through holes, preventing air and dust from passing through. Based on the above working process, when the indoor unit of this embodiment is turned off, air and dust cannot pass through the sealing area 232 of the filter 230. Therefore, dust and other debris are reduced from entering the casing 100 through the air inlet 110 and adhering to the heat exchanger or fan, resulting in a cleaner interior and improved cooling or heating performance of the indoor unit.

[0108] Alternatively, in some implementations, please refer to Figure 22 The sealing area 232 is made of plastic film, and a heat-fusion area for connecting the sealing area 232 and the filtering area 231 is provided between the sealing area 232 and the filtering area 231.
