Description

Technical Field

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

[0002] After prolonged use, dust accumulates on the air filter of wall-mounted air conditioners. If not cleaned regularly, this can clog the filter mesh, hindering airflow and reducing the effective air intake area. This leads to increased energy consumption and significantly impacts cooling and heating performance. Furthermore, excessive dust accumulation on the filter surface can breed bacteria, causing secondary air pollution and affecting indoor air quality.

[0003] Currently, the most common method for dust removal from filters on the market is manual disassembly and washing. After cleaning, consumers need to reinstall the filters, which is time-consuming, laborious, and inconvenient for users. Summary of the Invention

[0004] To overcome the problem of time-consuming and laborious manual cleaning of air conditioner filters in related technologies, this invention proposes a wall-mounted air conditioner indoor unit and a wall-mounted air conditioner. By setting a dust removal module in the extra space between the heat exchanger and the front panel of the indoor unit, it can achieve automatic dust removal of the filter without increasing the size of the whole unit, thus solving the problem of users having difficulty cleaning the filter.

[0005] The first aspect of this invention provides a wall-mounted air conditioner indoor unit, comprising:

[0006] chassis;

[0007] The air intake grille is located on the top side of the casing and has a grille track.

[0008] The heat exchanger is located inside the casing and is used to exchange heat with the airflow that enters the casing through the air inlet grille.

[0009] The front panel is located on the front side of the casing, and the front panel and the heat exchanger form an installation space.

[0010] The dust removal module is located within the installation space and includes a dust removal track and a cleaning mechanism.

[0011] The dust removal track and the grid track are connected to form a filter track for the filter screen to move. The filter screen is movably installed in the filter track. When the filter screen moves, it has a filtering position in the grid track and a dust removal position in the dust removal track. The cleaning mechanism is used to clean the filter screen when it moves between the filtering position and the dust removal position.

[0012] In the above technical solution, the grille track extends along the width direction of the indoor unit, and the dust removal track extends along the height direction of the indoor unit;

[0013] The dust removal track, which extends along the height of the indoor unit, has a curved section with a convex and a concave surface. The concave surface of the curved section is recessed towards the front of the heat exchanger.

[0014] In the above technical solution, the dust removal track is constructed as an S-shaped track with a curved section in the height direction of the indoor unit.

[0015] In the above technical solution, the dust removal module is detachably installed between the front of the heat exchanger and the front panel;

[0016] The dust removal module includes a dust removal cover and a dust removal bracket that fit together in the width direction of the indoor unit;

[0017] The dust removal bracket has a dust removal track, and the dust removal cover has a limiting structure, which is used to limit the movement of the filter screen.

[0018] In the above technical solution, the dust removal cover is a flat plate parallel to the front panel, and the dust removal bracket is an arc-shaped plate concave to the front of the heat exchanger.

[0019] The dust removal cover has a cover surface facing the dust removal bracket, the dust removal bracket has a bracket surface facing the dust removal cover, a dust removal track is formed on the bracket surface of the dust removal bracket, and a limiting structure is formed on the cover surface of the dust removal cover.

[0020] The limiting structure includes a rib protruding from the surface of the dust removal cover. When the dust removal cover is mated with the dust removal bracket, there is a distance between the protruding end of the rib and the bracket surface of the dust removal bracket to define a limiting track for the movement of the filter screen.

[0021] When the filter moves to the dust removal track position, at least a portion of the filter in the length direction of the indoor unit is located within the dust removal track and at least a portion is located within the limit track.

[0022] In the above technical solution, the protruding end of the rib has an S-shaped structure in the height direction of the indoor unit;

[0023] The convex rib with an S-shaped structure at the protruding end forms an S-shaped limiting track between itself and the support surface of the dust collector bracket for limiting the position of the filter screen.

[0024] In the above technical solution, multiple sets of grille tracks and dust removal tracks are provided, and the multiple sets of grille tracks and dust removal tracks are distributed along the length of the indoor unit.

[0025] When the filter moves to the dust removal track position, part of the filter is located within multiple dust removal tracks along the length of the indoor unit, and another part is located between two adjacent dust removal tracks.

[0026] The ribs are arranged along the length of the indoor unit between two adjacent dust removal tracks to limit the position of the filter screen between the two dust removal tracks;

[0027] At least one protruding rib is provided between two adjacent sets of dust removal tracks;

[0028] When a rib is provided between two adjacent sets of dust removal tracks, the rib, the dust removal track, the support surface of the dust removal bracket, and the cover surface of the dust removal cover plate form a dust falling space with openings at both the top and bottom.

[0029] When multiple ribs are provided between two adjacent sets of dust removal tracks, the two adjacent ribs, the support surface of the dust removal bracket, and the cover surface of the dust removal cover plate form a dust falling space with openings at both the top and bottom. The ribs, dust removal tracks, the support surface of the dust removal bracket, and the cover surface of the dust removal cover plate also form a dust falling space with openings at both the top and bottom.

[0030] In the above technical solution, the cleaning mechanism includes a brush assembly for cleaning the surface of the filter screen and a dust collection box for collecting the dust after cleaning.

[0031] The brush assembly is located at the top opening of the dust falling space, and the dust collection box is located at the bottom opening of the dust falling space.

[0032] The dust collection box has a collection port at the top, and at least part of the collection port is opposite to the bottom opening of the dust falling space to collect dust falling from the bottom opening of the dust falling space.

[0033] In the above technical solution, an air outlet is also provided at the front of the indoor unit;

[0034] The dust collection box is detachably installed at the front of the indoor unit and located above the air outlet;

[0035] The dust collection box also has an air vent on its side, and a filter is installed at the air vent. When the air is discharged from the air outlet, it can create a negative pressure at the air vent of the dust collection box, so as to draw the dust in the dust removal module into the dust collection box through the negative pressure.

[0036] In the above technical solution, the brush assembly includes a dust removal brush and a brush drive assembly for driving the dust removal brush to rotate. When the dust removal brush is driven to rotate by the brush drive assembly, it has an active cleaning position and a passive cleaning position.

[0037] When the dust removal brush rotates to the active cleaning position, it can contact the surface of the filter screen to clean the filter screen. When the dust removal brush rotates to the passive cleaning position, it can achieve self-cleaning.

[0038] In the above technical solution, the dust removal cover is also provided with protruding cleaning teeth;

[0039] When the dust removal brush is driven to rotate to the passive cleaning position, it can come into contact with the cleaning teeth to achieve self-cleaning of the dust removal brush.

[0040] In the above technical solution, the cleaning tooth includes a first cleaning tooth and a second cleaning tooth protruding from the surface of the dust removal cover plate;

[0041] Passive cleanup locations include the first passive cleanup location and the second passive cleanup location;

[0042] When the dust removal brush is driven to rotate to the first passive cleaning position, it can contact the first cleaning tooth; when the dust removal brush is driven to rotate to the second passive cleaning position, it can contact the second cleaning tooth.

[0043] The first and second cleaning teeth have different protrusion heights, so that different parts of the dust removal brush can be cleaned by cleaning teeth with different protrusion heights.

[0044] In the above technical solution, the dust removal cover is also provided with a limiting rib;

[0045] The limiting rib is used to limit the position of the dust removal brush when it rotates counterclockwise to the active cleaning position. The limiting rib is also used to limit the position of the dust removal brush when it rotates clockwise to the passive cleaning position.

[0046] In the above technical solution, the air intake grille is detachably installed on the top side of the housing, and the air intake grille forms an air inlet;

[0047] The air intake grille includes an upper air intake grille and a lower air intake grille that are connected vertically along the height of the indoor unit;

[0048] The upper and lower air intake grilles, which are connected vertically, form a grille track that extends along the width of the indoor unit.

[0049] In the above technical solution, the grille track includes a starting end near the rear of the indoor unit and a ending end near the front of the indoor unit in the width direction of the indoor unit.

[0050] The indoor unit of an air conditioner also includes:

[0051] A detection device is installed at the starting end of the grid track. The detection device is used to detect whether the filter screen has moved to the starting end of the grid track.

[0052] When the filter moves to the starting position of the grille track, the air inlet is blocked by the filter.

[0053] In the above technical solution, the indoor unit of the air conditioner also includes a filter drive device;

[0054] The filter drive unit includes:

[0055] A roller motor base is located between the grid track and the dust removal track;

[0056] A drum motor fixed on a drum motor mount;

[0057] A drum connected to a drum motor drive;

[0058] And the roller gear located on the roller;

[0059] The filter screen has teeth that mesh with the roller gear. The filter screen that meshes with the roller gear through the teeth can be driven to move in the filter screen track when the roller rotates.

[0060] In the above technical solution, when the motor mount is located between the grille track and the dust removal track, it is at least partially exposed outside the indoor unit;

[0061] The indoor unit of the air conditioner also includes a decorative cover, which is used to cover the exposed drum motor mount and at least part of the dust removal module.

[0062] A connecting track is defined between the decorative cover, the dust removal module, and the roller motor base for connecting the grille track and the dust removal track.

[0063] In the above technical solution, the filter screen has a first segment and a second segment in its moving direction, as well as an intermediate segment between the first segment and the second segment;

[0064] When the filter moves to the position that blocks the air inlet, the first and middle sections of the filter are located inside the grille track, and the second section of the filter is located inside the dust removal track.

[0065] When the filter moves to the position to avoid the air inlet, the second and middle sections of the filter are located in the dust removal track, and the first section of the filter is located in the grille track.

[0066] Some of the teeth on the filter screen are located on the middle section of the filter screen, and the other part is located on the first section and / or the second section of the filter screen.

[0067] A second aspect of the present invention provides a wall-mounted air conditioner, which includes an outdoor unit and the aforementioned indoor unit.

[0068] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0069] In this embodiment of the invention, by setting a dust removal module in the extra space between the heat exchanger of the indoor unit of the air conditioner and the front panel, the automatic dust removal function of the filter can be achieved without increasing the size of the whole unit, thereby solving the problem of users having difficulty cleaning the filter.

[0104] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0105] Currently, cleaning the filters in existing air conditioners is usually done manually, which is both time-consuming and laborious. This invention proposes a wall-mounted indoor unit and a wall-mounted air conditioner that, by incorporating a dust removal module in the extra space between the heat exchanger and the front panel of the indoor unit, can achieve automatic dust removal of the filters without increasing the overall size of the unit, thus solving the problem of users finding it difficult to clean the filters.

[0106] The following is in conjunction with the appendix Figure 1 - Appendix Figure 23 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0107] Example

[0108] like Figures 1-23 As shown, the first aspect of this invention provides a wall-mounted air conditioner indoor unit, comprising:

[0109] Casing 405;

[0110] Air intake grille 401 is located on the top side of housing 405, and air intake grille 401 has grille track 12.

[0111] Heat exchanger 20 is located inside the housing 405 and is used to exchange heat with the airflow entering the housing 405 through the air inlet grille 401.

[0112] Front panel 10 is located on the front side of housing 405, and the front panel 10 and heat exchanger 20 form an installation space.

[0113] The dust removal module 30 is located in the installation space and has a dust removal track 13 and a cleaning mechanism.

[0114] The dust removal track 13 and the grid track 12 are connected to form a filter track for the filter screen 2 to move. The filter screen 2 is movably arranged in the filter track. When the filter screen 2 moves, it has a filtering position in the grid track 12 and a dust removal position in the dust removal track 13. The cleaning mechanism is used to clean the filter screen 2 when it moves between the filtering position and the dust removal position.

[0115] In this embodiment of the invention, by setting a dust removal module 30 in the extra space between the heat exchanger 2 of the indoor unit of the air conditioner and the front panel 10, the automatic dust removal function of the filter screen 2 can be achieved without increasing the size of the whole unit, thereby solving the problem of users having difficulty cleaning the filter screen.

[0116] Specifically, the grille track 12 located at the top of the indoor unit and the dust removal track 13 located at the front of the indoor unit are connected to form a filter track. When the filter 2 moves in the filter track, the cleaning mechanism in the dust removal module 30 can clean the moving filter 2, thereby achieving an automatic cleaning effect on the filter 2.

[0117] It is worth noting that the orientation references described in the embodiments of the present invention are... Figures 15-17 The orientation markings in the diagram indicate that the front of the casing 405 is the side of the indoor unit that faces the user after installation, and the rear of the casing 405 is the side of the indoor unit that fits into the wall.

[0118] Specifically, such as Figures 15-18 As shown, the grille track 12 extends along the width direction of the indoor unit, and the dust removal track 13 extends along the height direction of the indoor unit.

[0119] The dust removal track 13, which extends along the height of the indoor unit, has a curved section 131. The curved section 131 has a convex surface and a concave surface, with the concave surface of the curved section 131 facing the front of the heat exchanger 20.

[0120] In this embodiment of the invention, by providing a curved section 131 to the dust removal track 13, the extra space between the heat exchanger 20 and the front panel 10 is fully utilized, thus avoiding excessive thickness of the entire unit (the thickness direction of the entire unit is...). Figure 15 The width direction indicated} On the other hand, by setting the curved part 131, the distance inside the dust removal module 30 in the width direction of the indoor unit can be increased, thereby facilitating the falling of dust inside the dust removal module 30 and making it easier to collect the dust.

[0121] It should be noted that the grille track 12 mentioned in the embodiments of the present invention extends along the width direction of the indoor unit. It is sufficient that the extension direction of the grille track 12 is generally along the width direction of the indoor unit. Similarly, the dust removal track 13 mentioned in the embodiments of the present invention extends along the height direction of the indoor unit. It is also sufficient that the extension direction of the dust removal track 13 is generally along the height direction of the indoor unit.

[0122] Better, such as Figure 18 As shown, the dust removal track 13 is constructed as an S-shaped track with a bend 131 in the height direction of the indoor unit.

[0123] In this embodiment of the invention, by setting the dust removal track 13 in an S-shape, the extra space between the heat exchanger 20 and the front panel 10 can be utilized to the maximum extent.

[0124] In any of the above embodiments, such as Figure 1 and Figure 2As shown, the dust removal module 30 is detachably installed between the front of the heat exchanger 20 and the front panel 10;

[0125] The dust removal module 30 includes a dust removal cover plate 301 and a dust removal bracket 302 that are mated together in the width direction of the indoor unit;

[0126] The dust removal bracket 302 has a dust removal track 13, and the dust removal cover plate 301 has a limiting structure. The limiting structure is used to limit the movement of the filter screen 2.

[0127] In this embodiment of the invention, the dust removal module 30 is made detachable and is arranged in a relatively docked form to facilitate subsequent cleaning of the dust removal module 30 by the user.

[0128] Furthermore, such as Figure 2 , Figure 11 , Figure 16 and Figure 17 As shown, the dust removal cover 301 is a flat plate parallel to the front panel 10, and the dust removal bracket 302 is an arc-shaped plate concave to the front of the heat exchanger 20.

[0129] It is worth noting that the dust removal cover 301 mentioned in the embodiments of the present invention is a flat plate parallel to the front panel 10. It only needs to be generally parallel to the front panel 10, and it is not required to be completely parallel to the front panel 10.

[0130] Furthermore, the dust removal cover 301 has a cover surface facing the dust removal bracket 302, the dust removal bracket 302 has a bracket surface facing the dust removal cover 301, a dust removal track 13 is formed on the bracket surface of the dust removal bracket 302, and a limiting structure is formed on the cover surface of the dust removal cover 301.

[0131] The limiting structure includes a protruding rib 3011 protruding from the cover surface of the dust removal cover 301. When the dust removal cover 301 and the dust removal bracket 302 are mated together, there is a distance between the protruding end of the rib 3011 and the bracket surface of the dust removal bracket 302, so as to define the limiting track 3014 for the filter screen 2 to move.

[0132] When the filter moves to the position of the dust removal track 13, at least a portion of the filter 2 in the length direction of the indoor unit is located within the dust removal track 13 and at least a portion is located within the limiting track 3014.

[0133] In this embodiment of the invention, by providing a protruding rib 3011 on the dust removal cover 301, the moving filter screen 2 can be limited, thereby improving the stability of the filter screen 2 when it moves.

[0134] Furthermore, such as Figure 2 , Figure 11 , Figure 16 and Figure 17 As shown, the protruding end of the rib 3011 has an S-shaped structure in the height direction of the indoor unit;

[0135] The convex rib 3011 with an S-shaped structure at the protruding end forms an S-shaped limiting track 3014 for limiting the filter screen 2 between the support surface of the dust removal bracket and the convex end.

[0136] Furthermore, such as Figure 2 , Figure 11 , Figure 16 and Figure 17 As shown, multiple sets of grille track 12 and dust removal track 13 are provided, and the multiple sets of grille track 12 and dust removal track 13 are distributed along the length of the indoor unit.

[0137] When the filter moves to the dust removal track 13, part of the filter is located within multiple dust removal tracks 13 along the length of the indoor unit, and another part is located between two adjacent dust removal tracks 13.

[0138] The convex rib 3011 is arranged along the length of the indoor unit between two adjacent dust removal tracks 13 to limit the filter screen located between the two dust removal tracks 1;

[0139] At least one rib 3011 is provided between two adjacent sets of dust removal tracks 12;

[0140] When a rib 3011 is provided between two adjacent sets of dust removal tracks 12, the rib 3011, the dust removal track 13, the support surface of the dust removal bracket 302 and the cover surface of the dust removal cover 301 form a dust falling space 3 with openings at the top and bottom.

[0141] When multiple protruding ribs 3011 are provided between two adjacent sets of dust removal tracks 12, the adjacent two protruding ribs 3011, the support surface of the dust removal bracket 302 and the cover surface of the dust removal cover 301 form a dust falling space 3 with openings at the top and bottom. The protruding ribs 3011, the dust removal track 13, the support surface of the dust removal bracket 302 and the cover surface of the dust removal cover 301 also form a dust falling space 3 with openings at the top and bottom.

[0142] In this embodiment of the invention, the dust removal module 30 is provided with an S-shaped dust removal track 13 and an S-shaped limiting track 3014 distributed along the length of the indoor unit. The two sides of the filter screen 2 in the length of the indoor unit can move in the S-shaped dust removal track 13, and the middle part can move in the S-shaped limiting track 3014.

[0143] Meanwhile, because the dust removal cover plate 301 is provided with protruding ribs 3011, the dust removal module 30 can also form a dust falling space 3 that is wide in the middle and narrow at the top and bottom, which makes it easier for the dust inside the dust removal module 30 to fall into the dust collection box 303, thus facilitating the collection of dust.

[0144] As can be seen from the above, the dust removal module 30 in this embodiment of the invention also includes a cleaning mechanism.

[0145] Specifically, such as Figure 2 and Figure 11 As shown, the cleaning mechanism includes a brush assembly for cleaning the surface of the filter screen 2, and a dust collection box 303 for collecting the dust after cleaning.

[0146] The brush assembly is located at the top opening of the dust falling space 3, and the dust collection box 303 is located at the bottom opening of the dust falling space 3.

[0147] The dust collection box 303 has a collection port on its top, and at least part of the collection port is opposite to the bottom opening of the dust falling space 3 to collect dust falling from the bottom opening of the dust falling space 3.

[0148] In this embodiment of the invention, the dust collection box 303 and the brush assembly are both integrated into the dust removal module 30. When the user needs to clean the dust inside the air conditioner, he or she simply removes the dust removal module 30 from the air conditioner, which is more convenient and faster.

[0149] Furthermore, the indoor unit is also equipped with an air outlet 14 at the front;

[0150] The dust collection box 303 is detachably installed at the front of the indoor unit and located above the air outlet 14;

[0151] In order to improve the dust collection effect of the dust collection box 303, in some embodiments not shown, an air vent can be provided on the side of the dust collection box 303, and a filter device can be provided at the air vent. In this way, when the air outlet 14 of the air conditioner blows air, a negative pressure can be formed at the air vent of the dust collection box 303, so that the dust in the dust removal module 30 can be adsorbed into the dust collection box 303 by the negative pressure, thereby improving the dust collection effect inside the air conditioner.

[0152] In any of the above embodiments, such as Figure 2 , Figures 16-22 As shown, the brush assembly includes a dust removal brush 304 and a brush drive assembly 305 that drives the dust removal brush 304 to rotate. When the dust removal brush 304 is driven to rotate by the brush drive assembly 305, it has an active cleaning position and a passive cleaning position.

[0153] When the dust removal brush 304 rotates to the active cleaning position, it can contact the surface of the filter screen 2 to clean the surface of the filter screen 2. When the dust removal brush 304 rotates to the passive cleaning position, it can achieve self-cleaning.

[0154] In other words, the dust removal brush 304 in this embodiment of the invention not only can clean the filter screen 2, but also can self-clean, thereby reducing the frequency of cleaning the brush assembly and improving the user experience.

[0155] Specifically, such as Figure 11 , Figures 16-22 As shown, the dust removal cover 301 is also provided with cleaning teeth 3012;

[0156] When the dust removal brush 304 is driven to rotate to the passive cleaning position, it can come into contact with the cleaning teeth 3012 to achieve self-cleaning of the dust removal brush 304.

[0157] In this embodiment of the invention, cleaning teeth 30112 are provided on the dust removal cover plate 301, and the cleaning teeth 3012 cooperate with the rotatable dust removal brush 304 to achieve the self-cleaning effect of the dust removal brush 304.

[0158] Furthermore, such as Figure 11 , Figures 16-22 As shown, the cleaning tooth 3012 includes a first cleaning tooth 30121 and a second cleaning tooth 30122 protruding from the cover surface of the dust removal cover plate 301.

[0159] Passive cleanup locations include the first passive cleanup location and the second passive cleanup location;

[0160] When the dust removal brush 304 is driven to rotate to the first passive cleaning position, it can contact the first cleaning tooth 30121; when the dust removal brush 304 is driven to rotate to the second passive cleaning position, it can contact the second cleaning tooth 30122.

[0161] The first cleaning tooth 30121 and the second cleaning tooth 30122 have different protrusion heights, so that different positions of the dust removal brush 304 can be cleaned by cleaning teeth with different protrusion heights.

[0162] Preferably, the protruding length of the first cleaning tooth 30121 is greater than the protruding length of the second cleaning tooth 30122. When the dust removal brush 304 is driven to rotate to the first passive cleaning position and contacts the first cleaning tooth 30121, the first cleaning tooth 30121 contacts the inside of the bristles of the dust removal brush 304, thereby shaking off the dust trapped inside the dust removal brush 304. When the dust removal brush 304 is driven to rotate to the second passive cleaning position and contacts the second cleaning tooth 30122, the second cleaning tooth 30122 contacts the surface of the bristles of the dust removal brush 304, thereby shaking off the dust trapped inside the brush 304. The dust is removed. In this embodiment of the invention, by setting cleaning teeth with different protrusion heights, the self-cleaning effect of the dust removal brush 304 can be guaranteed, and the service life of the dust removal brush 304 can be extended. {If the dust removal brush 304 only contacts the first cleaning tooth 30121, then the dust removal brush 304 will have a reduced bristle life due to prolonged contact with the longer first cleaning tooth 30121. If the dust removal brush 304 only contacts the second cleaning tooth 30122, then the shorter second cleaning tooth 30122 cannot guarantee effective cleaning of the dust removal brush 304.}

[0163] In any of the above embodiments, such as Figures 16-22 As shown, the dust removal cover is also provided with a limiting rib 3013;

[0164] The limiting rib 3013 is used to limit the position of the dust removal brush 304 when it rotates counterclockwise to the active cleaning position. The limiting rib 3013 is also used to limit the position of the dust removal brush 304 when it rotates clockwise to the passive cleaning position.

[0165] In any of the above embodiments, such as Figure 3 and Figure 4 As shown, the air intake grille 401 is detachably mounted on the top side of the housing 40, and the air intake grille 401 forms an air inlet 11.

[0166] The air intake grille 401 includes an upper air intake grille 4011 and a lower air intake grille 4012 that are connected vertically in the height direction of the indoor unit;

[0167] The upper air intake grille 4011 and the lower air intake grille 4012, which are connected vertically, form a grille track 12 that extends along the width of the indoor unit.

[0168] Specifically, the grille track 12 includes a starting end near the rear of the indoor unit and a ending end near the front of the indoor unit in the width direction of the indoor unit.

[0169] The indoor unit of an air conditioner also includes:

[0170] A detection device 402 is provided at the starting end of the grid track. The detection device 402 is used to detect whether the filter screen 2 has moved to the starting end of the grid track.

[0171] When the filter 2 moves to the starting position of the grille track, the air inlet 11 is blocked by the filter 2.

[0172] Preferred, such as Figure 4 and Figure 5 As shown, the detection device 402 described above includes a pendulum 4022 and a micro switch.

[0173] In this embodiment of the invention, a detection device 402 is provided to detect whether the filter screen 2 has moved into place when it moves, and the movement of the filter screen 2 can be automatically controlled according to the contact between the filter screen 2 and the detection device.

[0174] In any of the above embodiments, such as Figure 3 , Figures 8-10 As shown, the indoor unit of the air conditioner also includes a filter drive device 403;

[0175] The filter drive unit 403 includes:

[0176] Motor mount 4031 is located between the grid track 12 and the dust removal track 13;

[0177] A roller motor 4032 is fixed on the motor base 4031;

[0178] Drum 4033 is connected to drum motor 4032 via transmission;

[0179] And the roller gear 4034 is provided on the roller 4033;

[0180] The filter screen 2 is provided with teeth 21 that mesh with the roller gear 4034. The filter screen 2 that meshes with the roller gear 4034 through the teeth 21 can be driven to move in the filter screen track when the roller 4033 rotates.

[0181] It is worth noting that in this embodiment of the invention, the filter screen 2 is only provided with teeth 21 where it meshes with the roller gear 4034, and teeth 21 are not designed in other parts. This ensures the air intake volume of the air conditioner indoor unit while ensuring the movement of the filter screen 2. {If the teeth 21 on the filter screen 2 are set too long in the length direction of the indoor unit, it will affect the obstruction of the air inlet 11, thereby affecting the air intake volume of the air inlet 11}.

[0182] Furthermore, such as Figures 13-18 As shown, when the motor mount 4031 is located between the grille track 12 and the dust removal track 13, it is at least partially exposed outside the indoor unit;

[0183] The air conditioner indoor unit also includes a decorative cover 404, which is used to cover the motor mount 4031 and at least part of the dust removal module 30 exposed outside the indoor unit;

[0184] A connecting track 15 for connecting the grille track 12 and the dust removal track 13 is defined between the decorative cover 404, the dust removal module 30 and the motor base 4031.

[0185] In any of the above embodiments, such as Figure 23 As shown, the filter screen 2 has a first segment and a second segment in its direction of movement, as well as an intermediate segment between the first segment and the second segment;

[0186] When the filter screen 2 moves to the filtering position that blocks the air inlet 11, the first section and the middle section of the filter screen 2 are located in the grille track 12, and the second section of the filter screen 2 is located in the dust removal track 13.

[0187] When the filter screen 2 moves to the position to avoid the air inlet 11, the second and middle sections of the filter screen 2 are located in the dust removal track 13, and the first section of the filter screen 2 is located in the grille track 12.

[0188] A portion of the teeth 21 on the filter screen 2 are located on the middle section of the filter screen 2, and another portion is located on the first section and / or the second section of the filter screen 21.

[0189] In this embodiment of the invention, when the filter screen 2 moves, there is always a portion of the filter screen 2 in the grid track 12 and the dust removal track 13, that is, a portion of the filter screen 2 is always engaged with the roller gear when it moves, thereby improving the stability of the filter screen 2 when it moves.

[0190] To better understand the structural layout and working principle of the indoor unit in this embodiment of the invention, the following is a detailed explanation. Figures 1-23 Please provide a detailed explanation:

[0191] Specifically, the indoor unit structure layout in this embodiment of the invention is as follows:

[0192] like Figure 1 As shown, the indoor unit of the air conditioner in this embodiment of the invention is provided with a bottom shell component 70, a fan component 80, a control component 90, a heat exchange component (i.e., the heat exchanger 20 mentioned above), a side plate component 50, a front panel component 40, an air guide plate component 60, a dust removal module 30, and a front panel component (i.e., the front panel 10 mentioned above).

[0193] It is worth noting that, such as Figure 3 As shown, the panel body component 40 is composed of an air inlet grille 401, a detection device 402, a filter drive device 403, a decorative cover 404, a housing 405, and an air guide plate drive mechanism 406.

[0194] like Figure 3 As shown, panel body component 40 is provided with housing 405. Air guide plate drive mechanism 406 is fixed to both sides of housing 405 along its length by screws, used to drive air guide plate component 60. Roller motor 4032 and brush motor 3057 are respectively fixed to roller motor base 4031 and brush motor base by screws. The two motor bases are fixed to housing 405 and upper air inlet grille 4011 by screws. Figure 8 and Figure 9 As shown, the shaft end of the roller motor 4032 engages with the end shaft hole of the roller gear 4034 on the roller 4033. The other end of the roller gear 4034 engages with the middle hole of the lower air inlet grille 4012, thus fixing the roller 4033. A pendulum 4022 and a micro switch 4021 are provided between the upper air inlet grille 4011 and the lower air inlet grille 4012. The pendulum 4022 and the micro switch 4021 are used to check whether the front end of the filter screen 2 has moved to the designated position.

[0195] like Figure 2 As shown, the dust removal module 30 is provided with a dust removal cover plate 301, a dust removal bracket 302, a dust collection box 303, and a dust removal brush bracket 3053 fixed on the dust removal bracket 302. The dust removal brush bracket 3053 has a support rod 3052 in the middle. The support rod 3052 can be one or more metal rods with good rigidity, which are fixed in the middle by a central shaft sleeve 3054. The surface of the dust removal brush bracket 3053 is provided with a dust removal brush 304.

[0196] like Figure 18 As shown, the upper air inlet grille 4011 has an upper wall of grille track 12, the lower air inlet grille 4012 has a lower wall of grille track 12, the roller motor base 4031 has a lower wall of connecting track 15, the inner surface of the decorative cover 404 has an upper wall of connecting track 15, and the dust removal bracket 302 has an upper and lower wall of dust removal track 13. The grille track 12, connecting track 15 and dust removal track 13 together constitute the entire track for the filter screen to run. The track is S-shaped, which saves more space compared to other shapes.

[0197] in

[0198] The filter track installation steps are as follows:

[0199] Step 1: Secure the micro switch 4021 and the pendulum 4022 using the upper rail limit post and upper rail buckle on the upper air intake grille 4011.

[0200] Step 2: Insert the lower rail pin on the lower air intake grille 4012 into the upper rail pin hole of the upper air intake grille 4011. The lower rail limiting hole and the upper rail limiting buckle are engaged. The middle screw is tightened to complete the assembly of the upper air intake grille 4011 and the lower air intake grille 4012. After assembly, the two constitute the grille track mentioned above.

[0201] Step 3: Fix the roller motor 4032 and the brush motor 3057 to their respective motor mounts with screws. Insert the shaft of the roller motor 4032 into the roller gear shaft hole at the end of the 064 roller (0641). Insert the shaft of the brush motor 3057 into the crank 3056 hole. Insert the other end of the roller gear 4034 into the shaft hole of the lower air inlet grille. Secure the motor mount to the screw post on the upper air inlet grille 4011 with screws to complete the assembly of the roller 4033 and the air inlet grille 401.

[0202] Step 4: Insert the lower air intake grille limiting post and the upper air intake grille pin into the panel body limiting hole and the panel body pin hole respectively, and fix the motor base and the corresponding screws of the housing 405 to achieve the assembly of the track part of the panel body component 40.

[0203] Step 5: Fix the dust collector bracket 302 to the housing 405 with screws. Insert the toothed section of the front end of the filter screen 2 into the insertion port of the grille track 12 formed by the upper air inlet grille 4011 and the lower air inlet grille 4012 in the housing 405. Insert it along the track until the front end of the filter screen 2 touches the bottom of the grille track 12. Insert the toothless section of the end of the filter screen 2 into the insertion port of the dust collector track 13 formed on the dust collector bracket 302 to complete the assembly of the filter screen. The end of the filter screen 2 is reserved with a toothless end. The length of the toothless end should ensure that when the head of the filter screen is against the pendulum 4022, the end of the filter screen can extend at least 10mm into the dust collector track 13. The reason for designing the filter screen 2 in this way is that, on the one hand, the part of the filter screen 2 that extends into the dust collector track 13 does not need to cooperate with the roller gear 4034, and the end does not need to be added with teeth. On the other hand, this section is wider than the head, has better local strength, and is more conducive to inserting the end of the filter screen into the dust collector track 13.

[0204] Step 6: Fix the dust removal brush 304 to the dust removal brush bracket 3053 by adhesive. Insert the support rod 3052 into the corresponding hole of the dust removal brush bracket 3053. The two support rods 3052 are fixed in the middle by the central shaft sleeve 3054. The ends of the support rods 3052 are fixed by the end shaft sleeve 3051 and the crankshaft 3055 respectively. The pre-assembled dust removal brush 304 assembly is assembled with the dust removal cover plate 301 by the middle end cover 306 and the screws. Then, insert the crankshaft 3055 into the crank 3056. The dust removal cover plate 301 is fixed to the housing 405 by screws.

[0205] Step 7: Attach the buckles and pins on the dust collection box 303 to the corresponding mating holes on the dust removal bracket 301 to fix the dust collection box 303. Finally, insert the decorative cover 404 into the notch between the grille track 12 and the dust removal track 13. At this point, the entire filter movement track is fully assembled.

[0206] The disassembly steps for after-sales service of the filter screen and brush are as follows:

[0207] Step 1. First, remove the front panel 10 and the decorative cover 404 in sequence;

[0208] Step 2. Remove filter screen 2 and replace the dust removal brush 304 on the dust removal cover 30;

[0209] The steps for cleaning dust from the 303 dust collection box are as follows:

[0210] Step 1: Open the front panel 10 and hang the front panel 10 in the hinge slot of the casing 405;

[0211] Step 2. Remove the dust collection box 303.

[0212] The steps for dust control are as follows:

[0213] Step 1: Turn on manual or automatic dust removal mode;

[0214] Step 2: The fan system stops running to prevent dust from falling into the heat exchanger 20 from the air inlet 11 of the fan component 80 during the dust removal process.

[0215] Step 3: The control unit 90 first determines whether the front end of the filter screen 2 is at the top, i.e., whether the micro switch 4021 is working. If the front end of the filter screen is not at the designated position at the top, the roller motor 4032 runs, and the roller gear 4034 moves the filter screen 2 along... Figure 18 The filter screen track shown rotates counterclockwise until the front end of the filter screen 2 touches the pendulum 4022, and the other end of the pendulum 4022 touches the micro switch 4021. The micro switch 4021 drives the drum motor 4032 to stop running.

[0216] Step 4: The brush motor 3057 operates, moving the dust removal brush 304 to the position described above. Figure 22 The indicated position {avoids filter 2 and limiting rib 3013};

[0217] Step 5: The drum motor 4032 runs, and the filter screen 2 is moved along the drum gear 4034. Figure 18 The filter track shown moves clockwise according to the preset motor drive program to the position shown. Figure 17 As shown, in order to prevent the head of filter screen 2 from losing its teeth, after the set roller motor drive program is in place, one section of the toothed section of the head of filter screen 2 with at least 3 teeth is located in the grid track.

[0218] Step 6: The brush motor 3057 operates, moving the dust removal brush 304 clockwise to the position shown. Figure 19 The position shown is tangent to the horizontal position of roller 4033. This position has the largest effective area for brushing onto filter screen 2.

[0219] Step 7: The drum motor 4032 operates, and the filter screen 2 is moved along the drum gear 4034. Figure 18 The filter screen track shown rotates counterclockwise until the front end of the filter screen 2 touches the 4022 pendulum, and the other end of the pendulum 4022 touches the micro switch 4021. The micro switch 4021 drives the roller motor 4032 to stop running. At this time, it indicates that the dust removal brush 304 has finished brushing the filter screen 2.

[0220] Step 8: The brush motor 3057 runs, moving the dust removal brush 304 counterclockwise to the position shown. Figure 20 or Figure 21 The dust on the dust removal brush 304 is cleaned by the first cleaning teeth 30121 and the second cleaning teeth 30122 on the dust removal cover 301.

[0221] Step 9: The brush motor 3057 operates, moving the dust removal brush 304 to the position described above. Figure 22 Location.

[0222] In summary, the wall-mounted air conditioner indoor unit provided in this embodiment of the invention can add an automatic dust removal function without increasing the overall size of the unit, solving the problem of users having difficulty cleaning the filter. At the same time, by setting the dust removal module 30 as a detachable modular component, this embodiment of the invention facilitates consumers or after-sales personnel to further clean the dust inside the dust removal module 30 and replace the filter 2 and dust removal brush 304.

[0223] A second aspect of the present invention also provides a wall-mounted air conditioner, which includes an outdoor unit and the aforementioned indoor unit.
