Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and more specifically, to a wall-mounted air conditioner indoor unit. Background Technology

[0002] As consumers have increasingly higher requirements for the performance and functions of air conditioners, there is a need to design air conditioners with novel and convenient functions to meet user needs.

[0003] Existing automatic dust removal systems for filters work by moving the filter so that it is in contact with a brush, allowing the brush to clean the filter. However, in actual use, some dust clumps up on the filter, resulting in poor cleaning by the brush and affecting the filter's normal filtration efficiency. Utility Model Content

[0004] This application provides a wall-mounted air conditioner indoor unit to at least solve the technical problem that, during actual use, some dust will clump on the filter or brush, resulting in poor cleaning effect of the brush on the filter and affecting the normal filtration effect of the filter.

[0005] According to a first aspect of the embodiments of this application, a wall-mounted air conditioner indoor unit is provided, comprising: The housing has an air inlet formed on its top; A heat exchanger is disposed inside the housing, a top space is defined between the top of the heat exchanger and the air inlet at the top of the housing, and a front space is defined between the front of the heat exchanger and the front of the housing. A sliding track is provided inside the housing. The sliding track includes a top section of the track located in the top space and a side section of the track that communicates with the top section of the track and is located in the front space. A filter screen is movably disposed in the sliding track, and the filter screen has a top position on the top section of the track and a side position on the side section of the track when it moves; A cleaning mechanism is provided inside the housing. The cleaning mechanism includes a brush assembly and a drive motor for driving the brush assembly to rotate. The brush assembly has two opposing sides along the radial direction of its rotation. One side has a cleaning brush, and the other side is provided with an electric heating element. The brush assembly has a first position and a second position when it is driven to rotate. When the brush assembly is in the first position, the cleaning brush contacts the surface of the filter screen and can clean the surface of the filter screen. When the brush assembly is in the second position, the electric heating element faces the filter screen and can heat the filter screen.

[0006] In this embodiment, during the movement of the filter screen, the cleaning mechanism can rub against the filter screen to clean it, removing a large amount of dirt adhering to the filter screen. This prevents a large amount of dirt from accumulating on the filter screen, which not only affects the filtration performance but also the air permeability, thus affecting the normal operation of the indoor unit of the air conditioner. The brush assembly can also rotate. When rotated to a first position, the brush assembly can contact the filter screen for cleaning. It can also rotate to a second position, where it can contact the cleaning component. During this contact, the cleaning component cleans the brush assembly, achieving a self-cleaning effect. This prevents excessive dirt accumulation on the brush assembly, which would affect its cleaning effect on the filter screen and avoid secondary contamination of the filter screen by the accumulated dirt.

[0007] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the brush assembly further includes: a mounting frame; The mounting frame is rotatably connected to the housing, and the cleaning brush and the electric heating element are respectively disposed on both radial sides of the axis on which the mounting frame and the housing are rotatably connected. In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the cleaning brush includes a cleaning head and a root, the root being disposed on the mounting frame; Both the mounting frame and the root are made of thermally conductive material, and the electric heating element can conduct heat to the root of the cleaning brush through the mounting frame; Alternatively, the mounting frame may be provided with an air cavity containing a fan, the electric heating element may be disposed within the air cavity, and the air cavity may have an air outlet; when the cleaning brush cleans the surface of the filter screen, the electric heating element and the fan may be controlled to blow hot air through the air outlet to the area of ​​the filter screen being cleaned by the cleaning brush.

[0008] Using this method, the electric heating element can contact the base of the cleaning brush, allowing the heat generated by the electric heating element to be quickly transferred to the cleaning brush. It can also contact the mounting frame, allowing the heat generated by the electric heating element to be transferred to the cleaning brush through the mounting frame. At the same time, the heat can also be better transferred to the filter screen. Of course, it can also contact both the cleaning brush and the mounting frame simultaneously, making full and effective use of the heat energy generated by the electric heating element to dry the dust faster.

[0009] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the installation frame includes: The frame is rotatably connected to the housing, and the frame is provided with a brush mounting part, in which the base of the cleaning brush is disposed. A connecting bracket is disposed on the side of the frame opposite to the mounting port of the cleaning brush, and the electric heating element is connected to the connecting bracket.

[0010] In conjunction with the first aspect, in an optional implementation of this application embodiment, the cleaning mechanism further includes: The cleaning teeth are disposed on the inner wall of the housing and are located at a position corresponding to the brush assembly, so that when the brush assembly is in the first position, the electric heating element can be directed toward the cleaning teeth to heat the cleaning teeth. When the brush assembly is in the second position, the cleaning brush can be in contact with the cleaning teeth to achieve cleaning of the cleaning brush.

[0011] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the sliding track further includes a track bending section, and the top section of the track and the side section of the track are connected through the track bending section; The track bending section is a curved arc structure, and the track bending section protrudes at least a predetermined distance from the front side of the track side section toward the front space. When the brush assembly is in the first position, it can contact the filter screen surface located in the track bending section to clean it.

[0012] In this implementation, the sliding track consists of a top section, a side section, and a bend section. The bend section curves forward relative to the side section, preventing dust from falling onto the side section during filter cleaning. Furthermore, the bend section bends a certain distance further forward from its lower protrusion into the front of the front space, further preventing dust from falling onto the side section. This structure allows the entire sliding track to form a... The near-S-shaped sliding track not only makes full use of the limited space inside the casing, reserving ample room for the filter to move, avoiding an overall thicker casing, reducing the space required for the indoor unit, and improving the user experience, but also allows the brush assembly to be placed at the bends of the track. Due to this S-shaped sliding track design, dust falling vertically will not stick to the filter located on the side track section, thus avoiding secondary pollution. This also allows the dust generated by the brush assembly cleaning the filter to fall more effectively from top to bottom.

[0013] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the wall-mounted air conditioner indoor unit further includes: A dust collection box, located in the front space, is used to collect dust that falls off the filter screen when the cleaning mechanism cleans it. The dust collection box is detachably embedded in the front space.

[0014] By adopting this implementation method, the dust collection box can be detachably set in the front space of the front of the casing, making it convenient for users to remove the dust collection box and deal with the dust in the dust collection box.

[0015] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the wall-mounted air conditioner indoor unit further includes: A humidity sensor is disposed on the brush assembly; A controller is used to acquire the humidity sensor and control the electric heating element to heat the filter and / or brush assembly.

[0016] This implementation method allows for adjustment of dust levels based on data returned by the humidity sensor. It prevents damp dust from adhering to the filter, which could cause excessive resistance during winding or even jamming in the track. Dust with moderate moisture content can fall off as much as possible from the contact point between the filter and the brush, and then into the drawer. It also prevents dust from adhering to the brush assembly, thus avoiding interference with the brush assembly's cleaning effect on the filter.

[0017] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the controller is further configured to control the brush assembly to rotate clockwise when the brush assembly cleans the filter screen, and to control the filter screen to stop moving when the filter screen is in a second position during the rotation of the brush assembly, wherein the filter screen moves when it is in the first position and the moving speed is not greater than the rotation speed of the brush assembly.

[0018] Using this implementation method, the brush assembly can be rotated by the controller when cleaning the filter screen. This allows the brush assembly to clean the filter screen while simultaneously performing self-cleaning, improving the cleaning effect of the brush assembly on the filter screen and preventing too much dust from adhering to the brush assembly, which would affect the cleaning effect. Furthermore, the rotation direction of the brush assembly can be clockwise. Clockwise rotation of the brush assembly can move the dust on the filter screen to the front side of the front space, allowing the dust to fall smoothly into the dust collection box and preventing dust from accumulating at the bends in the front space.

[0019] According to a second aspect of the embodiments of this application, a control method for a wall-mounted air conditioner indoor unit is provided. The control method includes: acquiring the humidity value of the brush assembly and / or the front space, and drying the brush assembly and / or the filter when the humidity value reaches a preset value.

[0020] In conjunction with the second aspect, in an optional implementation of the embodiments of this application, drying the brush assembly and / or the filter screen includes: Rotate the mounting frame to a first position to clean the surface of the filter screen with the cleaning brush and heat the cleaning teeth with the electric heating element; or drive the mounting frame to a second position to clean the cleaning brush with the cleaning teeth and heat the filter screen with the electric heating element.

[0021] According to an embodiment of the present invention, a wall-mounted air conditioner indoor unit has a sliding track inside the casing. The filter screen is movably mounted in this sliding track. During the movement of the filter screen, it can rub against the brush assembly of the cleaning mechanism, thereby achieving the self-cleaning function of the filter screen. During this friction cleaning process, the filter screen is heated to dry the dust on it, preventing dust from clumping on the filter screen and ensuring the cleaning effect of the brush assembly on the filter screen. This keeps the filter screen clean and effectively performs its filtering function, preventing the air inlet of the air conditioner indoor unit from being blocked or allowing a large amount of dust to enter. Moreover, the electric heating element and the cleaning brush are arranged opposite each other and can rotate, so that the brush assembly can not only clean the filter screen with the cleaning brush, but also rotate to allow the electric heating element to face the filter screen and quickly heat it, evaporating the moisture on the filter screen.

[0030] Based on this, such as Figures 1-4 As shown, the wall-mounted air conditioner indoor unit according to an embodiment of the present utility model includes: a housing 1, and an air inlet 2 is formed on the top of the housing 1; Heat exchanger 3 is located inside the casing 1. The top of the heat exchanger 3 is defined by the air inlet 2 at the top of the casing 1, and the front of the heat exchanger 3 is defined by the front of the casing 1. The sliding track 4 is located inside the housing 1. The sliding track 4 includes a top section 41 located in the top space and a side section 42 connected to the top section 41 and located in the front space. The filter screen 5 is movably disposed in the sliding track 4, and when moving, the filter screen 5 has a top position located at the top section 41 of the track and a side position located at the side section 42 of the track. The cleaning mechanism 6 is located inside the housing 1. The cleaning mechanism 6 includes a brush assembly 62 and a drive motor for driving the brush assembly 62 to rotate. The brush assembly 62 has two opposite sides in the radial direction along its rotation axis. One side has a cleaning brush 621, and the other side is provided with an electric heating element 12. The brush assembly 62 has a first position and a second position when it is driven to rotate. When the brush assembly 62 is in the first position, the cleaning brush 621 contacts the surface of the filter screen 5 and can clean the surface of the filter screen 5. When the brush assembly 62 is in the second position, the electric heating element 12 faces the filter screen 5 and can radiate heat to the filter screen 5.

[0031] Specifically, in the embodiments of this utility model, after installation, the top of the wall-mounted air conditioner indoor unit 1 faces the ceiling, the bottom of the unit 1 faces the base plate, the front of the unit 1 faces the user, and the rear of the unit 1 faces the wall, which is also the side that matches the wall.

[0032] The filter 5 can be a dust filter 5. The air entering the casing 1 from the air inlet 2 can be filtered through the filter 5 to remove dust and large particulate impurities, so as to prevent a large amount of dust from entering the casing 1 and affecting the normal operation of the indoor unit of the air conditioner.

[0033] The filter screen 5 is installed in the sliding track 4 and can move within the sliding track 4. During the movement of the filter screen 5 in the sliding track 4, the cleaning mechanism 6 can perform friction cleaning on the filter screen 5. That is, when the filter screen 5 needs to be cleaned, it can be moved from the top section 41 of the track to the side section 42 of the track. During the movement of the filter screen 5, the cleaning mechanism 6 can generate relative friction with the filter screen 5 to clean the filter screen 5, remove a large amount of dirt attached to the filter screen 5, and avoid a large amount of dirt accumulating on the filter screen 5, which would not only affect the filtration performance of the filter screen 5, but also affect the air permeability of the filter screen 5, thus affecting the normal operation of the indoor unit of the air conditioner.

[0034] The cleaning mechanism 6 performs cleaning through the brush assembly 62. When the cleaning mechanism 6 cleans the filter screen 5 through the brush assembly 62, that is, when the filter screen 5 moves relative to the brush assembly 62, the filter screen 5 and / or the brush assembly 62 can be heated. Specifically, this can be done by setting a new heating component, such as an electric heating element 12, or by using the air conditioner's own heating or dehumidifying mode. The air guide plate through the air outlet directs the hot airflow to the area where the filter screen 5 is located, heating the filter screen 5 and / or the brush assembly 62. Heating evaporates the moisture on the filter screen 5 and / or the brush assembly 62, drying the dust and preventing it from clumping. Alternatively, it can make clumped dust easier to break up, ensuring the cleaning effect of the brush assembly 62 on the dust. This prevents clumped dust from failing to fall off the filter screen 5 or sticking to the brush assembly 62, thus keeping the filter screen 5 clean and enabling it to effectively perform its filtering function. This prevents the air inlet 2 of the indoor unit of the air conditioner from becoming blocked or allowing a large amount of dust to enter.

[0035] The cleaning mechanism 6 can rotate under the drive of the drive motor. Its cleaning brush 621 can contact the surface of the filter screen 5 at the first position and clean the surface of the filter screen 5. When the brush assembly 62 is in the second position, the electric heating element 12 faces the filter screen 5 and can radiate heat to the filter screen 5, thereby drying the filter screen 5 and preventing dust from clumping on the filter screen 5.

[0036] The wall-mounted air conditioner indoor unit may also include: a dust removal bracket 10 and a dust removal cover 11. The dust removal bracket 10 and the dust removal cover 11 are fastened together to form a front space. The dust removal cover 11 is used to separate the heat exchanger 3 from the front space. The front space is formed by the dust removal bracket 10 and the dust removal cover 11 fastened together. The dust removal cover 11 is close to the heat exchanger 3 and can separate the heat exchanger 3, preventing dust from falling onto the heat exchanger 3 and affecting the normal operation of the heat exchanger 3.

[0037] According to an embodiment of the present invention, a wall-mounted air conditioner indoor unit has a sliding track 4 inside the casing 1. The filter screen 5 is movably disposed in the sliding track 4. During the movement of the filter screen 5, the filter screen 5 can rub against the brush assembly 62 of the cleaning mechanism 6, thereby realizing the self-cleaning function of the filter screen 5. During this friction cleaning process, by heating the filter screen 5 and / or the brush assembly 62, the dust on the filter screen 5 and / or the brush assembly 62 can be dried, preventing dust from clumping on the filter screen 5 and / or the brush, thus ensuring the cleaning effect of the brush assembly 62 on the filter screen 5, keeping the filter screen 5 clean, and effectively playing a filtering role, preventing the air inlet 2 of the air conditioner indoor unit from being blocked or allowing a large amount of dust to enter. Moreover, the electric heating element and the cleaning brush are arranged opposite each other and can rotate, so that the brush assembly can not only clean the filter screen with the cleaning brush, but also rotate to make the electric heating element face the filter screen to quickly heat the filter screen and evaporate the moisture on the filter screen.

[0038] Optionally, in one implementation of this embodiment, the brush assembly 62 further includes: a mounting frame 622; The mounting frame 622 is rotatably connected to the housing 1, and the cleaning brush 621 and the electric heating element 12 are respectively arranged on both radial sides of the axis on which the mounting frame 622 is rotatably connected to the housing 1.

[0039] Optionally, in one implementation of this embodiment, the cleaning brush 621 includes a cleaning head and a root, with the root disposed on the mounting frame 622; Both the mounting frame 622 and the base are made of thermally conductive material, and the electric heating element 12 can conduct heat to the base of the cleaning brush 621 through the mounting frame. Alternatively, the mounting frame 622 may be provided with an air chamber equipped with a fan, and the electric heating element 12 may be disposed in the air chamber, which has an air outlet; when the cleaning brush 621 cleans the surface of the filter screen 5, the electric heating element 12 and the fan are controlled to blow hot air through the air outlet to the area of ​​the filter screen 5 being cleaned by the cleaning brush 621.

[0040] Specifically, the electric heating element 12 can contact the base of the cleaning brush 621, such as by making it into a heating rod shape, so that the heat generated by the electric heating element 12 can be quickly transferred to the cleaning brush 621. Alternatively, it can contact the mounting frame 622, so that the heat generated by the electric heating element 12 can be transferred to the cleaning brush 621 through the mounting frame 622. This allows the cleaning brush 621 to be heated while it is cleaning. On the one hand, this can prevent the dust on the cleaning brush 621 from clumping due to moisture. On the other hand, the cleaning brush 621, which has a certain amount of heat, can also radiate heat to the filter screen 5, thus heating the filter screen 5.

[0041] Optionally, in one implementation of this embodiment, the mounting frame 622 includes: The frame 6221 is rotatably connected to the housing 1. The frame 6221 is provided with a brush mounting part 6222. The root of the cleaning brush 621 is set in the brush mounting part 6222, and the head of the cleaning brush 621 extends out from the frame 6221. A connecting bracket 6223 is located on the side opposite to the mounting port of the frame 6221 and the cleaning brush 621, and the electric heating element 12 is connected to the connecting bracket 6223.

[0042] Optionally, in one implementation of this embodiment, the cleaning mechanism 6 further includes: The cleaning teeth 61 are disposed on the inner wall of the housing 1 and are located at a position corresponding to the brush assembly 62, so that when the brush assembly 62 is in the first position, the electric heating element 12 can be directed toward the cleaning teeth 61 to heat the cleaning teeth 61. When the brush assembly 62 is in the second position, the cleaning brush 621 can be in contact with the cleaning teeth 61 to achieve cleaning of the cleaning brush 621.

[0043] Specifically, the cleaning teeth 61 can be installed and fixed on the inner wall of the housing 1, or it can be integrally formed with the inner wall of the housing 1. The brush assembly 62 can rotate. When the brush assembly 62 rotates to the first position, it can contact the filter screen 5 to clean the filter screen 5. The brush assembly 62 can also rotate to the second position. When the brush assembly 62 rotates to the second position, it can not only contact the cleaning teeth 61, but also continue to rotate and move relative to the cleaning teeth 61. Alternatively, the cleaning teeth 61 can be installed through a moving mechanism. The moving mechanism makes the cleaning teeth 61 reciprocate, so that the cleaning teeth 61 move relative to the brush assembly 62 when in contact. In this way, the brush assembly 62 can be cleaned by the cleaning teeth 61 during the contact process, achieving a self-cleaning effect. This prevents excessive dirt accumulation on the brush assembly 62, which would affect the cleaning effect of the brush assembly 62 on the filter screen 5, and also avoids secondary pollution of the filter screen 5 by the dirt accumulated on the brush assembly 62.

[0044] The cleaning teeth 61 may include a first layer of cleaning teeth 611 and a second layer of cleaning teeth 612. The first layer of cleaning teeth 611 has a plurality of first protrusions arranged in a row along the horizontal direction. The second layer of cleaning teeth 612 has a plurality of second protrusions arranged in two rows along the horizontal direction, and the two rows of second protrusions are staggered in the vertical direction. The length of the second protrusions in the vertical direction is less than the length of the first protrusions in the vertical direction. The first layer of cleaning teeth 611 and the second layer of cleaning teeth 612 are respectively used to clean different dirt on the brush 621 component 62. The first layer of cleaning teeth 611 can be a row of long comb-like structures. The first layer of cleaning teeth 611 mainly cleans the lint and hair-like substances attached to the brush assembly 62. The second layer of cleaning teeth 612 can be two rows of short, staggered structures. The second layer of cleaning teeth 612 mainly cleans the particulate and powdery substances attached to the brush assembly 62. The first layer of cleaning teeth 611 and the second layer of cleaning teeth 612 work together to clean the brush assembly 62 more effectively. In the specific cleaning process, the brush assembly 62 can first rotate to the position of the first layer of cleaning teeth 611, and then rotate about 45° to the position of the second layer of cleaning teeth 612.

[0045] The mounting frame 622 can be made of metal, which can conduct heat better. Multiple vents can also be provided on the mounting frame 622 to transfer the heat generated by the electric heating element 12 to the filter screen 5 more efficiently. Of course, both of the above can be combined to avoid the heat generated by the electric heating element 12 being trapped inside the mounting frame 622, which would affect the heating effect on the filter screen 5.

[0046] Optionally, in one implementation of this embodiment, an air outlet is formed at the bottom of the housing 1, and an air guide plate is provided at the air outlet of the housing 1. When the cleaning mechanism 6 cleans the filter screen 5, the wall-mounted air conditioner indoor unit can discharge hot air from the air outlet and guide the hot air to the top area of ​​the housing 1 through the air guide plate to heat the filter screen 5 and / or the brush assembly 62.

[0047] Specifically, since the air conditioner itself can have a heating mode and / or a dehumidification mode, it can discharge hot air through the air outlet. By adjusting the angle of the air guide plate, the hot air can be directed towards the upper area of ​​the indoor unit of the air conditioner. Thus, without adding new heating components, the air conditioner can adjust the mode and air guide plate of the indoor unit to achieve the heating and drying of the filter 5 and / or cleaning components.

[0048] The filter 5 and / or brush assembly 62 can be heated by the electric heating element 12, or the brush assembly 62 can be heated by adjusting the air guide plate through the dehumidification mode or heating mode of the indoor unit of the air conditioner. Alternatively, both heating methods can be used together to improve the heating and drying efficiency.

[0049] Optionally, in one implementation of this embodiment, the sliding track 4 further includes a track bending section 43, and the top section 41 of the track and the side section 42 of the track are connected through the track bending section 43. Among them, the track bending section 43 is a curved arc structure, and the track bending section 43 protrudes at least a preset distance from the front side of the track side section 42 to the front of the front space. When the brush assembly 62 is in the first position, it can contact the filter screen 5 in the track bending section 43 to clean it.

[0050] Specifically, the sliding track 4 consists of a top section 41, a side section 42, and a bent section 43. The bent section 43 bends forward relative to the side section 42 towards the front of the space, preventing dust from falling onto the side section 42 during cleaning of the filter 5. Furthermore, the bent section 43 bends a certain distance further forward from its lower protrusion towards the rear of the space, further preventing dust from falling onto the side section 42. This structure allows the entire sliding track 4 to form... An approximately "S"-shaped sliding track 4 not only makes full use of the limited space inside the housing 1, reserving ample space for the filter 5 to move, avoiding an overall increase in the thickness of the housing 1, reducing the space required for the indoor unit of the air conditioner, and improving the user experience, but also works in conjunction with the brush assembly 62 located at the bend section 43 of the track. Due to this "S"-shaped sliding track 4 design, dust falling longitudinally will not stick to the filter 5 located on the side track section, thus avoiding secondary pollution. This allows the dust generated by the brush assembly 62 cleaning the filter 5 to fall more effectively from top to bottom.

[0051] Optionally, in one implementation of this embodiment, the wall-mounted air conditioner indoor unit further includes: Dust collection box 8 is located in the front space and is used to collect dust that falls off when the cleaning mechanism 6 cleans the filter screen 5. The dust collection box 8 is detachably embedded in the front space.

[0052] Specifically, by detachably placing the dust collection box 8 in the front space of the front of the housing 1, it is convenient for the user to remove the dust collection box 8 and handle the dust in the dust collection box 8.

[0053] A weight sensor can also be installed in the dust collection box 8. After the brush assembly 62 finishes dust removal, the indoor unit can determine whether the weight of the dust collection box has reached the preset value. If the preset value is reached, a reminder will be issued and the user can disassemble and clean the pull-out box.

[0054] Optionally, in one implementation of this embodiment, the wall-mounted air conditioner indoor unit further includes: A humidity sensor is mounted on the brush assembly 62. The controller is used to control the electric heating element 12 to heat the filter screen 5 and / or brush assembly 62 by acquiring the humidity sensor. And / or control the wall-mounted air conditioner indoor unit to discharge hot air from the air outlet and guide the hot air to the top area of ​​the casing 1 through the air guide plate, and heat the filter 5 and / or brush assembly 62.

[0055] Specifically, the dust condition is adjusted based on data returned by the humidity sensor. This prevents damp dust from adhering to the filter 5, which could cause excessive resistance during winding or even jamming in the track. Dust with moderate humidity can fall off as much as possible from the contact point between the filter 5 and the brush, and then into the pull-out box. It also prevents dust from adhering to the brush assembly 62, which would affect the cleaning effect of the brush assembly 62 on the filter 5.

[0056] Optionally, in one implementation of this embodiment, the controller is further configured to control the brush assembly 62 to rotate clockwise when the brush assembly 62 is cleaning the filter screen 5, and to control the filter screen 5 to stop moving when the filter screen 5 is in the second position during the rotation of the brush assembly 62, and to move the filter screen 5 when the filter screen 5 is in the first position, and the moving speed is not greater than the rotation speed of the brush assembly 62.

[0057] Specifically, the wall-mounted air conditioner indoor unit may also include: a drive device, which includes a roller 9 rotatably disposed between the top section 41 and the side section 42 of the track. The roller 9 and the filter screen 5 are driven by gear meshing, thereby driving the filter screen 5 to move.

[0058] The length of the filter screen 5 can be designed such that when the filter screen 5 is in the top or side position, at least part of the filter screen 5 is engaged with the roller 9 by gears, which can ensure that the filter screen 5 never disengages during operation.

[0059] During the cleaning process of the brush assembly 62 on the filter screen 5, the drive device can be controlled by the controller, thereby controlling the movement state of the filter screen 5. The movement state of the filter screen 5 can include the moving speed and start / stop. The controller can also control the movement state of the brush assembly 62, which can include the rotation direction and rotation speed. The controller can make the brush assembly 62 rotate when cleaning the filter screen 5, so that the brush assembly 62 can clean the filter screen 5 while achieving self-cleaning, improving the cleaning effect of the brush assembly 62 on the filter screen 5, and preventing too much dust from adhering to the brush assembly 62, which would affect the cleaning effect of the brush assembly 62 on the filter screen 5.

[0060] Example 2 According to the control method of the wall-mounted air conditioner indoor unit of this utility model embodiment, the wall-mounted air conditioner indoor unit is the aforementioned wall-mounted air conditioner indoor unit, and the control method includes: Obtain the humidity value of the brush assembly 62 and / or the front space, and when the humidity value reaches the preset value, dry the brush assembly 62 and / or the filter 5.

[0061] Optionally, in one implementation of this embodiment, drying the brush assembly 62 and / or the filter 5 includes: Rotate the mounting frame 622 to drive it to the first position so that the surface of the filter screen 5 can be cleaned by the cleaning brush 621 and the cleaning teeth 61 can be heated by the electric heating element 12. Alternatively, drive the mounting frame 622 to the second position so that the cleaning brush 621 can be cleaned by the cleaning teeth 61 and the filter screen 5 can be heated by the electric heating element 12.

[0062] Specifically, the process of cleaning the filter screen 5 while simultaneously self-cleaning can be as follows: The brush assembly 62 rotates continuously. When the brush assembly 62 moves to the first position, it contacts the filter screen 5, and at this time, the rotational speed of the brush assembly 62 is greater than the moving speed of the filter screen 5. This allows the brush assembly 62 to generate dynamic friction with the filter screen 5, cleaning it. When the brush assembly 62 moves to the second position, i.e., when it is no longer in contact with the filter screen 5, the filter screen 5 stops moving, and the brush assembly 62 can contact the cleaning teeth 61 through the second position, achieving self-cleaning. When the brush assembly 62 rotates back to the first position, the above process is repeated.

[0063] The brush assembly 62 can rotate clockwise. The clockwise rotation of the brush assembly 62 can move the dust on the filter screen 5 to the front side of the front space, so that the dust can fall smoothly into the dust collection box 8 and avoid dust accumulation at the bend of the front space.

[0064] The electric heating element 12 added in this application, with its ingenious positioning, allows the electric heating element 12 to dry the cleaning teeth 61 while the brush assembly 62 rotates to clean the filter screen 5. This prevents dust from accumulating on the cleaning teeth 61. When the cleaning brush 621 rotates to the cleaning teeth 61 for self-cleaning, the electric heating element 12 dries the filter screen 5, preventing dust from accumulating on it. Throughout the process, the electric heating element 12 can also continuously heat the cleaning brush 621, preventing dust buildup on it. Furthermore, the cleaning brush 621, with its heat, also has a certain heat radiation effect, which can heat the filter screen 5 and the cleaning teeth 61, thus achieving the function of heating and cleaning simultaneously, resulting in a better dust removal effect.
