Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner indoor units, in particular to an air conditioner indoor unit. BACKGROUND

[0002] In some special application scenarios, due to the poor working environment of the air conditioner indoor unit, it needs to be overhauled and maintained from time to time, especially the filter screen in the air conditioner indoor unit, which needs to be cleaned or replaced every certain period of time to prevent the filter screen from being blocked and affecting the performance of the air conditioner indoor unit.

[0003] In the related art, the filter screen usually needs to be disassembled and assembled with both hands, but for the ceiling-mounted or suspended air conditioner indoor unit, since the installation position of the air conditioner indoor unit is high, it is extremely inconvenient to disassemble and assemble the filter screen with both hands. CONTENT OF THE UTILITY MODEL

[0004] In view of the above problems in the related art, the present application provides an air conditioner indoor unit to solve the problem of inconvenient disassembly and assembly of the filter screen in the related art.

[0005] In order to solve the above technical problems, in a first aspect, the present application provides an air conditioner indoor unit, which comprises:

[0006] A shell, the shell surrounds an internal space, and the shell is provided with an air inlet and an air outlet which communicate with the internal space;

[0007] A fan, the fan is arranged in the internal space and is used to suck air outside the shell into the internal space through the air inlet;

[0008] A heat exchanger, the heat exchanger is arranged in the internal space and is used to exchange heat with the air sucked into the internal space, and the fan is further used to blow the air after heat exchange out of the internal space through the air outlet;

[0009] A filter screen assembly, the filter screen assembly is movably arranged in the shell along a first direction, the filter screen assembly is used to cover the air inlet and filter the air entering the air inlet when the filter screen assembly is moved to a preset position along the first direction, and the filter screen assembly is provided with a stop portion; and

[0010] A locking assembly, the locking assembly is arranged in the shell and comprises:

[0011] A lock catch, the lock catch is rotatably arranged along a second direction, and the filter screen assembly is used to push the lock catch to rotate in a forward direction along the second direction to a reverse prevention position and make the lock catch located on the reverse side of the first direction of the stop portion during the forward movement of the filter screen assembly to the preset position along the first direction;

[0012] The reverse preventing component is used to prevent reverse rotation of the lock catch in the second direction when the lock catch is rotated to the reverse preventing position, so that the lock catch is in abutting engagement with the stop portion in the first direction.

[0013] In this way, when the filter screen assembly needs to be installed, the filter screen assembly can be pushed to move in the first direction to the preset position, and during movement of the filter screen assembly in the first direction to the preset position, the filter screen assembly pushes the lock catch to rotate in the second direction to the reverse preventing position, and the lock catch is located on the side opposite to the first direction of the stop portion. When the lock catch is rotated to the reverse preventing position, the reverse preventing component prevents reverse rotation of the lock catch in the second direction, so that the lock catch located on the side opposite to the first direction of the stop portion is in abutting engagement with the stop portion in the first direction, thereby preventing reverse movement of the filter screen assembly in the first direction, and installation of the filter screen assembly at the preset position is completed.

[0014] When the filter screen assembly needs to be dismounted, the filter screen assembly is only pushed to continue rotation of the lock catch in the second direction from the reverse preventing position, the reverse preventing component releases the prevention of reverse rotation of the lock catch in the second direction, and the lock catch also does not prevent reverse movement of the filter screen assembly in the first direction, so that the filter screen assembly can move in the first direction in reverse, and dismounting is completed.

[0015] According to the above, since installation and dismounting of the filter screen assembly can be completed by pushing the filter screen assembly to move, compared with the related art, the present application does not need complicated two-hand cooperation during installation and dismounting of the filter screen assembly, and installation and dismounting of the filter screen assembly can be completed by pushing the filter screen assembly with one hand, even if the installation position of the air conditioner indoor unit is high, installation and dismounting of the filter screen assembly can be completed by pushing the filter screen assembly with one hand, so that installation and dismounting of the filter screen assembly are facilitated.

[0016] In a second aspect, the present application further provides an air conditioner indoor unit, which comprises:

[0017] A housing, which encloses an internal space, and is provided with an air inlet and an air outlet which communicate with the internal space.

[0018] A fan, which is arranged in the internal space, and is used to suck air outside the housing into the internal space through the air inlet.

[0019] A heat exchanger, which is arranged in the internal space, and is used to exchange heat of the air sucked into the internal space, and the fan is further used to blow the heat-exchanged air out of the internal space through the air outlet.

[0020] a filter screen assembly movably arranged on the casing along a first direction, the filter screen assembly being used to cover the air inlet when being moved to a preset position along the first direction, and being used to filter air entering the air inlet, the filter screen assembly being provided with a stop portion; and

[0021] a locking assembly arranged on the casing and comprising:

[0022] a lock catch rotatably arranged along a second direction, the lock catch being configured to rotate to a reverse prevention position along a forward direction of the second direction when the filter screen assembly is moved to the preset position along a forward direction of the first direction, the lock catch being located on a reverse side of the stop portion along the forward direction of the first direction;

[0023] a reverse prevention subassembly used to prevent the lock catch from rotating along a reverse direction of the second direction when the lock catch is rotated to the reverse prevention position, so that the lock catch prevents the filter screen assembly from moving along a reverse direction of the first direction, and the reverse prevention subassembly being used to release the prevention of the lock catch from rotating along the reverse direction of the second direction when the filter screen assembly continues to move along the forward direction of the first direction.

[0024] In this way, when the filter screen assembly needs to be installed, the filter screen assembly can be pushed to move along the forward direction of the first direction to the preset position on the casing, and when the filter screen assembly is moved to the preset position along the forward direction of the first direction, the lock catch will not only rotate to the reverse prevention position along the forward direction of the second direction, but also be located on the reverse side of the stop portion along the forward direction of the first direction. When the lock catch is rotated to the reverse prevention position, the reverse prevention subassembly prevents the lock catch from rotating along the reverse direction of the second direction, so that the lock catch located on the reverse side of the stop portion along the forward direction of the first direction prevents the filter screen assembly from moving along the reverse direction of the first direction, thereby completing the installation of the filter screen assembly at the preset position.

[0025] When the filter screen assembly needs to be dismounted, the filter screen assembly only needs to be continuously pushed to move along the forward direction of the first direction, the reverse prevention subassembly releases the prevention of the lock catch from rotating along the reverse direction of the second direction, and then the lock catch also does not prevent the filter screen assembly from moving along the reverse direction of the first direction, so that the filter screen assembly can move along the reverse direction of the first direction to complete the dismounting operation.

[0026] According to the above, since the installation and dismounting of the filter screen assembly can be completed by only pushing the filter screen assembly to move, compared with the related art, the installation and dismounting of the filter screen assembly only needs to be performed by one hand, and even if the indoor unit of the air conditioner is installed at a high position, the installation and dismounting of the filter screen assembly can also be completed by one hand, thereby facilitating the installation and dismounting of the filter screen assembly.

[0027] Optionally, the locking assembly further comprises:

[0028] A locking shell, the locking shell encloses a mounting space, the reverse prevention component is arranged in the mounting space, the lock catch comprises a mounting portion and an abutting portion, the mounting portion is rotatably arranged in the mounting space along the second direction, the abutting portion is arranged outside the locking shell, and the abutting portion is used for abutting with the filter screen assembly.

[0029] In this way, for the reverse prevention component, the locking shell can play a certain protective role on the reverse prevention component, avoid interference from external factors, and ensure that the reverse prevention component can stably and reliably play a function. For the lock catch, not only can the mounting portion be protected by the locking shell, but also the abutting portion outside the locking shell can normally play a role, thereby ensuring that the locking assembly can normally operate.

[0030] Optionally, the lock catch comprises:

[0031] A lock catch body, the mounting portion is arranged on the lock catch body.

[0032] A roller, the roller is rotatably arranged on the lock catch body, and the roller is the abutting portion.

[0033] In this way, during movement of the filter screen assembly and contact of the abutting portion of the lock catch, since the rotatable roller is used as the abutting portion, the abutting portion can form rolling cooperation with the filter screen assembly. In this way, on one hand, the resistance that needs to be overcome when the filter screen assembly pushes the lock catch to rotate can be greatly reduced, so that the whole pushing process is more smooth, easy, convenient, efficient. On the other hand, the friction between the abutting portion and the filter screen assembly can be reduced, thereby being beneficial to reducing the wear of the lock catch and the filter screen assembly, and being beneficial to prolonging the service life of the lock catch and the filter screen assembly.

[0034] Optionally, the reverse prevention component comprises:

[0035] A sliding groove, the sliding groove is arranged on the inner wall of the locking shell, and comprises a first guide groove segment, a reverse prevention groove segment and a second guide groove segment arranged in sequence and in communication with each other, and the reverse prevention structure is arranged in the sliding groove.

[0036] A movable piece, the movable piece is provided with a hinged portion and a sliding portion, the hinged portion is hinged to the non-rotation axis of the lock catch, and the sliding portion is slidably arranged in the sliding groove.

[0037] The lock catch rotating in the forward direction along the second direction is used to drive the sliding part to slide into the second guide groove segment from the first guide groove segment.

[0038] In this way, during the process that the filter assembly pushes the lock catch to rotate in the forward direction along the second direction to the reverse position, the rotating lock catch drives the movable piece to move, so that the sliding part on the movable piece can slide into the reverse groove segment from the first guide groove segment, and then the reverse structure prevents the sliding part in the reverse groove segment from sliding into the first guide groove segment, that is, the reverse of the rotation of the lock catch along the second direction is prevented, so that the lock catch is located in the reverse position.

[0039] When the filter assembly continues to push the lock catch to rotate in the forward direction along the second direction, the lock catch drives the sliding part to slide into the second guide groove segment. When the sliding part slides into the second guide groove segment, the sliding part can slide into the first guide groove segment from the second guide groove segment to reset the sliding part. Therefore, after the sliding part slides into the second guide groove segment, the lock catch can rotate in the reverse direction along the second direction to reset, that is, the reverse position assembly releases the prevention of the reverse rotation of the lock catch along the second direction, and the lock catch rotating in the reverse direction along the second direction can drive the sliding part to slide into the first guide groove segment from the second guide groove segment.

[0040] According to the above, through the precise guide mechanism of the sliding groove, the rotating action of the lock catch can be performed according to the set trajectory, avoiding action deviation, ensuring that the lock catch can be accurately positioned in different operation stages, thereby ensuring the smooth development of the entire filter assembly disassembly process.

[0041] In addition, the reverse position assembly is arranged as a structure including a sliding groove and a movable piece, so that the structural layout of the reverse position assembly is relatively compact, reducing the space occupation of the reverse position assembly, and facilitating the arrangement of the reverse position assembly in the reverse shell.

[0042] Optionally, the groove bottom wall of the first guide groove segment and the groove bottom wall of the reverse groove segment are arranged in a stepped manner, and the groove bottom wall of the reverse groove segment is arranged on the side of the groove bottom wall of the first guide groove segment away from the slot of the sliding groove, and the reverse structure includes a first step surface connected between the groove bottom wall of the first guide groove segment and the groove bottom wall of the reverse groove segment; or,

[0043] The groove bottom wall of the reverse stopping groove section comprises a first bottom wall section and a second bottom wall section, the first bottom wall section is connected with the groove bottom wall of the first guide groove section, the first bottom wall section and the second bottom wall section are arranged in a stepped manner, and the second bottom wall section is arranged on the side of the first bottom wall section away from the slot opening of the sliding groove, and the reverse stopping structure comprises a second step surface connected between the first bottom wall section and the second bottom wall section.

[0044] In this way, when the sliding part slides to the reverse stopping groove section, it will be blocked by the first step surface or the second step surface to slide to the first guide groove section. Because the step surface has a height difference, the sliding part cannot easily return in the reverse direction by overcoming the height difference, thereby effectively preventing the sliding part from sliding from the reverse stopping groove section to the first guide groove section, ensuring that the lock catch can stably be in the reverse stopping position, ensuring the reliability of the stopping cooperation between the lock catch and the filter screen assembly, so that the filter screen assembly will not be easily loosened or displaced due to accidental circumstances after being installed, and ensuring that the air conditioner indoor unit can normally perform air filtering work by relying on the filter screen assembly.

[0045] Optionally, the first guide groove section, the reverse stopping groove section, and the second guide groove section form a closed loop groove section, and the reverse stopping groove section is recessed towards the inner side of the closed loop groove section.

[0046] In this way, after the sliding part of the movable member enters the reverse stopping groove section, the groove side wall of the reverse stopping groove section can also limit the movement path of the sliding part, so that the sliding part is less likely to accidentally slide from the reverse stopping groove section to the first guide groove section, thereby enhancing the stability of the reverse stopping function and ensuring that the lock catch can be more reliably maintained in the reverse stopping position.

[0047] Optionally, the groove bottom wall of the first guide groove section and the groove bottom wall of the second guide groove section are arranged in a stepped manner, and the groove bottom wall of the first guide groove section is arranged on the side of the groove bottom wall of the second guide groove section away from the slot opening of the sliding groove.

[0048] In this way, after the sliding part of the movable member is reset to the first guide groove section from the second guide groove section, it will be blocked by the step surface between the groove bottom wall of the first guide groove section and the groove bottom wall of the second guide groove section to slide to the second guide groove section. Because the step surface has a height difference, the sliding part cannot easily return in the reverse direction by overcoming the height difference, thereby effectively preventing the sliding part from sliding from the first guide groove section to the second guide groove section, ensuring that the lock catch can be in the reverse stopping position when the filter screen assembly is installed next time, and thereby ensuring that the next installation of the filter screen assembly can be normally performed.

[0049] Optionally, the lock assembly further comprises:

[0050] A reset member is arranged in the mounting space and connected between the lock catch and the locking shell, and is used to drive the lock catch to rotate reversely in the second direction after the reverse prevention assembly releases the prevention of the lock catch.

[0051] In this way, after the reverse prevention assembly releases the prevention of the lock catch, the reset member drives the lock catch to rotate reversely in the second direction, so that the lock catch can be returned to the initial position in time after each operation, thereby avoiding affecting the installation operation of the filter screen assembly next time due to the uncertain position of the lock catch, and even avoiding damage to the lock catch or other related components.

[0052] Optionally, the reset member is a tension spring.

[0053] In this way, first, the tension spring can provide stable reset force for driving the lock catch to rotate reversely by virtue of the elastic restoring force of the tension spring; second, the tension spring has simple structure and low cost, so that the structure of the locking assembly can be simplified and the cost of the locking assembly can be reduced; and finally, the tension spring has high reliability and long service life, so that the reliability of the locking assembly can be enhanced and the service life of the locking assembly can be prolonged.

[0054] Optionally, the filter screen assembly comprises:

[0055] A mounting frame is sealingly connected to the inner wall of the air inlet through a sealing structure.

[0056] A filter screen is arranged on the inner side of the mounting frame.

[0057] In this way, the mounting frame is sealingly connected to the inner wall of the air inlet through the sealing structure, so that air that has not been filtered by the filter screen can be effectively prevented from entering the air conditioner indoor unit from the gap between the mounting frame and the air inlet, thereby effectively preventing oil fume from entering the air conditioner indoor unit, and facilitating the performance of the air conditioner indoor unit.

[0058] Optionally, the sealing structure comprises a sealing groove and a sealing protrusion, the sealing groove is used for inserting the sealing protrusion, and one of the sealing groove and the sealing protrusion is arranged on the inner wall of the air inlet and the other is arranged on the mounting frame.

[0059] In this way, first, the sealing groove and the sealing protrusion have relatively simple structures, and do not need complex sealing materials or high-cost sealing accessories, and mainly rely on the structural shape to achieve the sealing function, so that the sealing structure can be simplified by using the sealing groove and the sealing protrusion, thereby facilitating the processing and manufacturing of the sealing structure.

[0060] Second, when the sealing protrusion is completely inserted into the sealing groove, it also means that the filter screen assembly is accurately installed in place, so that the positioning of the filter screen assembly is facilitated by the cooperation of the sealing groove and the sealing protrusion.

[0061] Finally, the cooperation of the sealing groove and the sealing protrusion not only realizes the sealing function, but also enhances the stability of the connection between the installation frame and the air inlet to some extent, thereby enhancing the stability of the installation of the filter screen assembly.

[0062] Optionally, a direction perpendicular to the first direction and parallel to the plane where the filter screen is located is a third direction;

[0063] The sealing groove comprises a first sealing groove segment and a second sealing groove segment, the length directions of which extend along the first direction; the sealing protrusion comprises a first protrusion segment and a second protrusion segment, the length directions of which extend along the first direction; in the third direction, the first sealing groove segment and the second sealing groove segment are respectively arranged on two sides of the installation frame, and the first protrusion segment and the second protrusion segment are respectively arranged on the inner walls of two sides of the air inlet; the first protrusion segment and the second protrusion segment are respectively used for being inserted into the first sealing groove segment and the second sealing groove segment along the first direction.

[0064] In this way, not only can the sealing be realized through the first protrusion segment, the second protrusion segment, the first sealing groove segment and the second sealing groove segment in the third direction, but also, since the length directions of the first sealing groove segment and the second sealing groove segment extend along the first direction and the length directions of the first protrusion segment and the second protrusion segment extend along the first direction, and since the filter screen assembly is movably arranged in the first direction in the shell, when the filter screen assembly is installed, the movement of the filter screen assembly in the first direction can be guided through the guiding cooperation of the first protrusion segment and the second protrusion segment with the first sealing groove segment and the second sealing groove segment in the first direction, so that the filter screen assembly can be more accurately and quickly installed at the corresponding preset position of the air inlet.

[0065] Optionally, the sealing groove further comprises a third sealing groove segment, the third sealing groove segment being arranged on one side of the installation frame in the positive direction of the first direction, the length direction of the third sealing groove segment extending along the third direction;

[0066] The sealing protrusion further comprises a third protrusion segment, the third protrusion segment being arranged on one side inner wall of the air inlet in the positive direction of the first direction, the length direction of the third protrusion segment extending along the third direction, and the third protrusion segment being used for being inserted into the third sealing groove segment when the filter screen assembly moves to the preset position.

[0067] In this way, in the positive direction of the first direction, not only can the sealing be realized through the third sealing groove segment and the third protrusion segment, but also when the filter screen assembly moves to the preset position, the third protrusion segment is inserted into the third sealing groove segment, which has a precise positioning effect on the installation of the filter screen assembly, thereby facilitating the installation and positioning of the filter screen assembly in the positive direction of the first direction.

[0086] In addition, in addition to being used to indicate the orientation or positional relationship, the above-mentioned partial terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain dependent relationship or connection relationship in some cases. Those of ordinary skill in the art can understand the specific meaning of these terms in the present application according to the specific situation.

[0087] In addition, the terms "mounting", "setting", "provided with", "connection", "connected" should be broadly understood. For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two devices, elements or components. Those of ordinary skill in the art can understand the specific meaning of the above terms in the present application according to the specific situation.

[0088] In addition, the terms "first", "second", and the like are mainly used to distinguish different devices, elements or components (the specific types and structures can be the same or different), and are not intended to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0089] As described in the background of the present application, in some special application scenarios, due to the poor working environment of the air conditioner indoor unit, it needs to be maintained frequently, especially the filter screen in the air conditioner indoor unit, which needs to be cleaned or replaced every certain period of time to prevent the filter screen from being blocked and affecting the performance of the air conditioner indoor unit.

[0090] In the related art, the filter screen usually needs to be disassembled and assembled with both hands, but for the ceiling-mounted or suspended air conditioner indoor unit, since the installation position of the air conditioner indoor unit is high, it is extremely inconvenient to disassemble and assemble the filter screen with both hands.

[0091] In view of the above problems, the present application provides an air conditioner indoor unit to solve the problem of inconvenient disassembly and assembly of the filter screen in the related art.

[0092] The technical solutions of the present application will be further described below in combination with specific embodiments and drawings:

[0093] In some embodiments, as shown in Figure 1 The air conditioner indoor unit includes a housing 1, which encloses an internal space, and an air inlet 11 and an air outlet are arranged on the housing 1 and communicate with the internal space. In this way, the air inlet 11 can allow indoor air to enter the housing 1, and the air outlet can send the air processed by the air conditioner back to the room, thereby forming an effective air circulation system that can continuously adjust the temperature, humidity, and other parameters of the indoor air to maintain a comfortable indoor environment.

[0094] In some embodiments, the air conditioner indoor unit further includes a fan arranged in the above-mentioned internal space and configured to suck air outside the housing 1 into the above-mentioned internal space through the air inlet 11. In this way, the fan can make the air enter the housing 1 faster and more stably, which is conducive to stably and continuously providing air to be processed into the above-mentioned internal space and speeding up the rhythm of the entire indoor air circulation.

[0095] In some embodiments, the air conditioner indoor unit further includes a heat exchanger arranged in the above-mentioned internal space and configured to exchange heat with the air sucked into the above-mentioned internal space, and the fan is further configured to blow the heat-exchanged air out of the above-mentioned internal space through the air outlet.

[0096] In this way, since the heat exchanger can directly exchange heat with the air, it can quickly change the temperature of the air. This allows the air conditioner indoor unit to quickly start adjusting the indoor air temperature after receiving a temperature adjustment instruction set by the user. In this way, the indoor temperature can be raised in a short time, reducing the user's waiting time for the indoor temperature to rise, and this efficient heat exchange process also helps to meet the temperature adjustment demand while avoiding excessive energy consumption.

[0097] In addition, by the fan, the temperature, humidity and other environmental parameters of each part of the room can be adjusted more quickly, and the case of large temperature difference or humidity difference in different areas of the room is reduced.

[0098] In some embodiments, as shown in Figure 2 and Figure 3 , the air conditioner indoor unit further comprises a filter screen assembly 2, which is movably arranged in the first direction (such as the Y direction in Figure 3 ) in the shell 1, and the filter screen assembly 2 is used to cover the air inlet 11 and filter the air entering the air inlet 11 when moving to the preset position in the first direction, as shown in Figure 4 , the filter screen assembly 2 is provided with a stop portion 21.

[0099] In this way, by filtering the air entering the air inlet 11 through the filter screen assembly 2, it can effectively prevent unfiltered air from entering the interior of the air conditioner indoor unit, and further effectively prevent oil fume from entering the interior of the air conditioner indoor unit, which is beneficial to ensure the performance of the air conditioner indoor unit.

[0100] In some embodiments, as shown in Figure 3 and Figure 4 , the air conditioner indoor unit further comprises a locking assembly 3, which is arranged in the shell 1, and as shown in Figure 4 and Figure 5 , the locking assembly 3 comprises a lock catch 31, which is rotatably arranged in the second direction (such as the A direction in Figure 5 ), and the filter screen assembly 2 is used to push the lock catch to rotate in the forward direction of the second direction (such as the A1 direction in Figure 3 ) to the reverse prevention position and make the lock catch 31 located on the side of the reverse direction of the first direction (such as the Y2 direction in Figure 5 ) of the stop portion 21 during moving to the preset position in the forward direction of the first direction (such as the Y1 direction in Figure 4 ).

[0101] In this way, when the filter screen assembly 2 moves in the forward direction of the first direction to the preset position, the lock catch 31 can be automatically pushed to rotate in the forward direction of the second direction to the reverse prevention position, and the lock catch 31 will be located on the side of the reverse direction of the first direction of the stop portion 21, which is beneficial to conveniently prevent the filter screen assembly 2 from moving in the reverse direction of the first direction by the lock catch 31, and further beneficial to conveniently keep the filter screen assembly 2 at the preset position.

[0102] In some embodiments, as shown in Figure 5 , the locking assembly 3 further comprises a reverse prevention subassembly 32, which is used to prevent the lock catch 31 from rotating in the reverse direction of the second direction (such as the A2 direction in Figure 5The lock 31 rotates in the A2 direction to stop the stop part 21 in the first direction; the anti-reverse component 32 is also used to release the obstruction of the lock 31 from rotating in the second direction after the filter assembly 2 pushes the lock 31 from the anti-reverse position to rotate in the positive direction.

[0103] With this configuration, during the installation of the filter assembly 2, when the latch 31 rotates to the anti-reverse position, the anti-reverse sub-assembly 32 will function to prevent the latch 31 from rotating in the reverse direction in the second direction. In this way, the latch 31 located on the side of the stop part 21 in the reverse direction will cooperate with the stop part 21 in the first direction to prevent the filter assembly 2 from moving in the reverse direction in the first direction, so that the filter assembly 2 can be stably installed in the preset position.

[0104] When it is necessary to disassemble the filter assembly 2, simply push the filter assembly 2 to make the latch 31 continue to rotate from the anti-reverse position in the positive direction of the second direction. The anti-reverse component 32 will then release the obstruction of the latch 31 rotating in the reverse direction of the second direction. Consequently, the latch 31 will not prevent the filter assembly 2 from moving in the reverse direction of the first direction. Thus, the filter assembly can move in the reverse direction of the first direction, making it easier to complete the disassembly operation.

[0105] In some embodiments, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the indoor unit of the air conditioner includes a casing 1, a fan, a heat exchanger, a filter assembly 2, and a locking assembly 3. The casing 1 encloses an internal space, and has an air inlet 11 and an air outlet communicating with the internal space. The fan is located within the internal space and is used to draw air from outside the casing 1 into the internal space through the air inlet 11. The heat exchanger is located within the internal space and is used to exchange heat with the air drawn into the internal space. The fan also blows the heat-exchanged air out of the internal space through the air outlet.

[0106] Filter assembly 2 along the first direction (e.g.) Figure 3 The filter assembly 2, movably mounted on the housing 1 in the Y direction, and movable to a preset position along the first direction, is used to cover the air inlet 11 and to filter the air entering the air inlet 11, such as... Figure 4 As shown, the filter assembly 2 is provided with a stop part 21.

[0107] The locking component 3 is disposed on the housing 1, and as follows: Figure 4 and Figure 5 As shown, the locking assembly 3 includes a latch 31 and a backstop assembly 32. The latch 31 extends along the second direction (e.g., ...). Figure 5 The filter assembly 2 is rotatably configured in the positive direction (e.g., in the first direction) along the first direction. Figure 3 During the process of moving the latch (in the Y1 direction) to the preset position, the latch is pushed along the positive direction of the second direction (e.g., in the Y1 direction).Figure 5 to the first direction of the stop portion 21 (e.g., the Y2 direction in FIG. 6). Figure 4

[0108] The anti-reverse subassembly 32 is configured to prevent the lock catch 31 from rotating in the reverse direction of the second direction (e.g., the A2 direction in FIG. 6) when the lock catch 31 is rotated to the anti-reverse position, so that the lock catch 31 is in the stopper engagement with the stop portion 21 in the first direction; and the anti-reverse subassembly 32 is further configured to release the prevention of the lock catch 31 from rotating in the reverse direction of the second direction after the filter screen assembly 2 pushes the lock catch 31 to rotate in the forward direction of the second direction from the anti-reverse position. Figure 5

[0109] In this way, when the filter screen assembly 2 needs to be installed, the filter screen assembly 2 can be pushed to move in the forward direction of the first direction on the casing 1 to the preset position, and during the movement of the filter screen assembly 2 in the forward direction of the first direction to the preset position, the filter screen assembly 2 pushes the lock catch 31 to rotate in the forward direction of the second direction to the anti-reverse position, and the lock catch 31 is located on the reverse side of the first direction of the stop portion 21. When the lock catch 31 is rotated to the anti-reverse position, the anti-reverse subassembly 32 prevents the lock catch 31 from rotating in the reverse direction of the second direction, so that the lock catch 31 located on the reverse side of the first direction of the stop portion 21 is in the stopper engagement with the stop portion 21 in the first direction to prevent the filter screen assembly 2 from moving in the reverse direction of the first direction, thereby completing the installation of the filter screen assembly 2 at the preset position.

[0110] When the filter screen assembly 2 needs to be removed, the filter screen assembly 2 is only needed to be pushed to continue rotating the lock catch 31 in the forward direction of the second direction from the anti-reverse position, and the anti-reverse subassembly 32 releases the prevention of the lock catch 31 from rotating in the reverse direction of the second direction, so that the lock catch 31 does not prevent the filter screen assembly 2 from moving in the reverse direction of the first direction, and the filter screen assembly 2 can move in the reverse direction of the first direction to complete the removal operation.

[0111] According to the above, since the installation and removal of the filter screen assembly 2 can be completed by pushing the filter screen assembly 2 to move, compared with the related art, the installation and removal of the filter screen assembly 2 of the present application does not need complicated two-hand cooperation operation, and can be completed by pushing the filter screen assembly 2 with one hand, even if the installation position of the indoor unit of the air conditioner is high, the installation and removal of the filter screen assembly 2 can be completed by pushing the filter screen assembly 2 with one hand, thereby facilitating the installation and removal of the filter screen assembly 2.

[0112] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 ​​As shown, the air conditioner indoor unit comprises a casing 1, a fan, a heat exchanger, a filter screen assembly 2 and a locking assembly 3. The casing 1 encloses an internal space, and the casing 1 is provided with an air inlet 11 and an air outlet which communicate with the internal space. The fan is arranged in the internal space and is used to suck air outside the casing 1 into the internal space through the air inlet 11. The heat exchanger is arranged in the internal space and is used to exchange heat with the air sucked into the internal space, and the fan is also used to blow the heat-exchanged air out of the internal space through the air outlet.

[0113] The filter screen assembly 2 is movably arranged in the casing 1 along a first direction (e.g. Y direction in Figure 3 ), and the filter screen assembly 2 is used to cover the air inlet 11 and filter the air entering the air inlet 11 when it is moved to a preset position along the first direction. Figure 4 As shown, the filter screen assembly 2 is provided with a stop portion 21.

[0114] The locking assembly 3 is arranged in the casing 1, and as shown in Figure 4 and Figure 5 , the locking assembly 3 comprises a lock catch 31 and a reverse prevention subassembly 32. The lock catch 31 is rotatably arranged along a second direction (e.g. A direction in Figure 5 ), and when the filter screen assembly 2 is moved to the preset position along the positive direction of the first direction (e.g. Y1 direction in Figure 3 ), the lock catch 31 is configured to rotate to a reverse prevention position along the positive direction of the second direction (e.g. A1 direction in Figure 5 ), and the lock catch 31 is located on the side of the stop portion 21 in the reverse direction of the first direction (e.g. Y2 direction in Figure 4 ).

[0115] The reverse prevention subassembly 32 is used to prevent the lock catch 31 from rotating in the reverse direction of the second direction (e.g. A2 direction in Figure 5 ) when the lock catch 31 is rotated to the reverse prevention position, so that the lock catch 31 prevents the filter screen assembly 2 from moving in the reverse direction of the first direction; and the reverse prevention subassembly 32 is also used to release the prevention of the lock catch 31 from rotating in the reverse direction of the second direction when the filter screen assembly 2 continues to move in the positive direction of the first direction.

[0116] In this way, when it is necessary to install the filter screen assembly 2, the filter screen assembly 2 can be pushed to move along the positive direction of the first direction towards the preset position on the casing 1, and when the filter screen assembly 2 is moved to the preset position along the positive direction of the first direction, the lock catch 31 will not only rotate to the reverse prevention position along the positive direction of the second direction, but also be located on the side of the stop portion 21 in the reverse direction of the first direction under the pushing of the filter screen assembly 2. When the lock catch 31 is rotated to the reverse prevention position, the reverse prevention subassembly 32 will play a role in preventing the lock catch 31 from rotating in the reverse direction of the second direction, so that the lock catch 31 located on the side of the stop portion 21 in the reverse direction of the first direction will prevent the filter screen assembly 2 from moving in the reverse direction of the first direction, thereby completing the installation of the filter screen assembly 2 at the preset position.

[0117] When the filter assembly 2 needs to be disassembled, the filter assembly 2 is only pushed to continue moving in the positive direction of the first direction, the reverse subassembly 32 is released from the prevention of the reverse rotation of the lock catch 31 in the second direction, and then the lock catch 31 cannot prevent the reverse movement of the filter assembly 2 in the first direction, so that the filter assembly 2 can move reversely in the first direction to complete the disassembly operation.

[0118] According to the above, since the installation and disassembly of the filter assembly 2 can be completed by only pushing the filter assembly 2 to move, compared with the related art, the installation and disassembly of the filter assembly 2 do not need complicated two-hand cooperation operation, and the installation and disassembly of the filter assembly 2 can be completed by only pushing the filter assembly 2 with one hand, even if the installation position of the indoor unit of the air conditioner is high, the installation and disassembly of the filter assembly 2 can be completed by pushing the filter assembly 2 with one hand, so that the installation and disassembly of the filter assembly 2 are facilitated.

[0119] In some embodiments, as shown in Figure 4 the filter assembly 2 is provided with a locking cavity 22, and the stop portion 21 is formed by a cavity wall surrounding the locking cavity 22, in this case, when the lock catch 31 is located on the reverse side of the first direction of the stop portion 21, the lock catch 31 also enters the locking cavity 22.

[0120] In this way, on the one hand, when the lock catch 31 enters the locking cavity 22, the cavity wall of the locking cavity 22 can limit the lock catch 31 from multiple directions, so that the activity range of the lock catch 31 can be more effectively limited, so that accidental displacement, shaking or falling out of the lock catch 31 is difficult to occur, and the reliability of the stop cooperation between the lock catch 31 and the filter assembly 2 is greatly enhanced.

[0121] On the other hand, the cavity wall of the locking cavity 22 can provide better protection for the lock catch 31 against external force interference, further ensuring the reliability of the stop cooperation between the lock catch 31 and the filter assembly 2.

[0122] In some embodiments, the filter assembly 2 is provided with a stop plate, and the stop portion 21 is formed by the stop plate. In this way, the structure of the filter assembly 2 can be simplified to a certain extent, which is conducive to facilitating the processing and manufacturing of the filter assembly 2.

[0123] In some embodiments, as shown in Figure 4 and Figure 5 the locking assembly 3 further includes a locking shell 33, the locking shell 33 surrounds an installation space, and the reverse subassembly 32 is arranged in the installation space. The lock catch 31 includes an installation portion 311 and an abutting portion 312, the installation portion 311 is rotatably arranged in the installation space in the second direction, and the abutting portion 312 is arranged outside the locking shell 33 and is used for abutting with the filter assembly 2.

[0124] In this way, for the check subassembly 32, the locking shell 33 can protect the check subassembly 32 from external interference, so as to ensure that the check subassembly 32 can stably and reliably play a function. For the lock catch 31, not only can the installation portion 311 be protected by the locking shell 33, but also the abutting portion 312 outside the locking shell 33 can normally play a role, thereby ensuring that the locking assembly 3 can normally operate.

[0125] In some embodiments, as shown in Figure 4 and Figure 5 , the lock catch 31 includes a lock catch body 313 and a roller, the installation portion 311 is arranged on the lock catch body 313, and the roller is rotatably arranged on the lock catch body 313. The roller is the abutting portion 312.

[0126] In this way, during the movement of the filter screen assembly 2 and the contact with the abutting portion 312 of the lock catch 31, since the rotatable roller is used as the abutting portion 312, the abutting portion 312 can form a rolling fit with the filter screen assembly 2. In this way, on the one hand, the resistance that needs to be overcome when the filter screen assembly 2 pushes the lock catch 31 to rotate can be greatly reduced, so that the whole pushing process is more smooth, easy, convenient and efficient. On the other hand, the friction between the abutting portion 312 and the filter screen assembly 2 can be reduced, thereby being beneficial to reducing the wear of the lock catch 31 and the filter screen assembly 2 and being beneficial to prolonging the service life of the lock catch 31 and the filter screen assembly 2.

[0127] In some embodiments, as shown in Figure 5 , the check subassembly 32 includes a sliding groove 321 and a movable piece 322. The sliding groove 321 is arranged on the inner wall of the locking shell 33, as shown in Figure 6 , the sliding groove 321 includes a first guide groove segment 3211, a check groove segment 3212 and a second guide groove segment 3213 arranged in sequence and connected with each other in a head-to-tail manner, and the check structure is arranged in the sliding groove 321.

[0128] As shown in Figure 5 and Figure 6 , the movable piece 322 is provided with a hinged portion 3221 and a sliding portion 3222. The hinged portion 3221 is hinged to the non-rotation axis of the lock catch 31, and the sliding portion 3222 is slidably arranged in the sliding groove 321.

[0129] The lock catch 31 rotating in the positive direction of the second direction (such as the A1 direction in Figure 5 is used to drive the sliding portion 3222 to slide into the check groove segment 3212 and the second guide groove segment 3213 from the first guide groove segment 3211 in sequence. The check structure is used to prevent the sliding portion 3222 in the check groove segment 3212 from sliding into the first guide groove segment 3211, so that the lock catch 31 is located at the check position. The lock catch 31 rotating in the reverse direction of the second direction (such as the A2 direction inFigure 5 The rotating lock 31 (rotating in the A2 direction in FIG. 6) is used to drive the sliding part 3222 to slide from the second guide groove segment 3212 into the first guide groove segment 3211.

[0130] In this way, during the process of the filter screen assembly 2 pushing the rotating lock 31 to rotate in the positive direction of the second direction to the reverse prevention position, the rotating lock 31 drives the movable part 322 to move, so that the sliding part 3222 on the movable part 322 can slide from the first guide groove segment 3211 into the reverse prevention groove segment 3212, and then the reverse prevention structure prevents the sliding part 3222 in the reverse prevention groove segment 3212 from sliding into the first guide groove segment 3211, that is, prevents the rotating lock 31 from rotating in the reverse direction of the second direction, so that the rotating lock 31 is located at the reverse prevention position.

[0131] When the filter screen assembly 2 continues to push the rotating lock 31 to rotate in the positive direction of the second direction, the rotating lock 31 drives the sliding part 3222 to slide into the second guide groove segment 3213. When the sliding part 3222 slides into the second guide groove segment 3213, the sliding part 3222 can slide from the second guide groove segment 3213 into the first guide groove segment 3211, so as to reset the sliding part 3222. Therefore, after the sliding part 3222 slides into the second guide groove segment 3213, the rotating lock 31 can rotate in the reverse direction of the second direction to reset, that is, the reverse prevention subassembly 32 releases the prevention of the rotating lock 31 from rotating in the reverse direction of the second direction, and the rotating lock 31 rotating in the reverse direction of the second direction drives the sliding part 3222 to slide from the second guide groove segment 3213 into the first guide groove segment 3211.

[0132] According to the above description, the rotating action of the rotating lock 31 can be performed according to the set trajectory through the precise guide mechanism of the sliding groove 321, so as to avoid action deviation and ensure that the rotating lock 31 can be accurately positioned at different operation stages, thereby ensuring the smooth development of the entire filter screen assembly 2 disassembly process.

[0133] In addition, the reverse prevention subassembly 32 is arranged to include the sliding groove 321 and the movable part 322, so that the structural layout of the reverse prevention subassembly 32 is relatively compact, the space occupation of the reverse prevention subassembly 32 is reduced, and the setting of the reverse prevention subassembly 32 in the locking shell 33 is facilitated.

[0134] In some embodiments, the reverse prevention subassembly 32 includes a torsional spring and a clamping groove, the clamping groove is arranged in the locking shell, the torsional spring is installed on the rotating shaft of the rotating lock 31, one end of the torsional spring is fixed on the locking shell 33, and the other end is connected with the rotating lock 31.

[0135] When the lock catch 31 is rotated in the positive direction of the second direction to the reverse prevention position, the elastic force of the torsion spring causes a protruding portion on the lock catch 31 to be clamped into a clamping groove, thereby preventing the lock catch 31 from being rotated in the reverse direction of the second direction. When it is necessary to release the reverse prevention, the torsion spring is further twisted in the process of the filter screen assembly 2 pushing the lock catch 31 to continue to be rotated in the positive direction of the second direction, so that the protruding portion is caused to be out of the clamping groove, thereby releasing the prevention of the reverse rotation of the lock catch 31.

[0136] In this way, the reverse prevention function is realized by using the elastic force of the torsion spring, the structure is compact, the space occupied is small, and the torsion spring can provide stable elastic force, thereby ensuring the reliability of the reverse prevention.

[0137] In some embodiments, the groove bottom wall of the first guide groove segment 3211 and the groove bottom wall of the reverse prevention groove segment 3212 are arranged in a stepped manner, and the groove bottom wall of the reverse prevention groove segment 3212 is arranged on the side of the groove bottom wall of the first guide groove segment 3211 away from the slot opening of the sliding groove 321. The reverse prevention structure includes a first step surface connected between the groove bottom wall of the first guide groove segment 3211 and the groove bottom wall of the reverse prevention groove segment 3212.

[0138] In this way, when the sliding part 3222 slides to the reverse prevention groove segment 3212, it will be blocked by the first step surface to slide to the first guide groove segment 3211. Because there is a height difference between the first step surface, the sliding part 3222 cannot easily return in the reverse direction to cross the height difference, thereby effectively preventing the sliding part 3222 from sliding from the reverse prevention groove segment 3212 to the first guide groove segment 3211, ensuring that the lock catch 31 can stably be in the reverse prevention position, ensuring the reliability of the stop cooperation between the lock catch 31 and the filter screen assembly 2, so that the filter screen assembly 2 will not be easily loosened or shifted due to accidental conditions after being installed, and ensuring that the air conditioner indoor unit can normally perform air filtering work by relying on the filter screen assembly 2.

[0139] In some embodiments, as shown in Figure 6 The groove bottom wall of the reverse prevention groove segment 3212 includes a first bottom wall segment and a second bottom wall segment, the first bottom wall segment is connected with the groove bottom wall of the first guide groove segment 3211, the first bottom wall segment and the second bottom wall segment are arranged in a stepped manner, and the second bottom wall segment is arranged on the side of the first bottom wall segment away from the slot opening of the sliding groove 321. The reverse prevention structure includes a second step surface 3214 connected between the first bottom wall segment and the second bottom wall segment.

[0140] With this configuration, when the sliding part 3222 slides to the anti-reverse groove section 3212, it will be blocked by the second step surface 3214 when it tries to slide into the first guide groove section 3211. Because there is a height difference in the second step surface 3214, the sliding part 3222 cannot easily cross this height difference to return in reverse, thus effectively preventing the sliding part 3222 from sliding from the anti-reverse groove section 3212 into the first guide groove section 3211. This ensures that the latch 31 can be stably in the anti-reverse position, guaranteeing the reliability of the stop cooperation between the latch 31 and the filter assembly 2. This ensures that the filter assembly 2 will not easily loosen or shift due to unexpected situations after installation, guaranteeing that the indoor unit of the air conditioner can normally rely on the filter assembly 2 to perform air filtration.

[0141] In some embodiments, the anti-reverse structure includes an elastic anti-reverse piece disposed between the anti-reverse groove section 3212 and the first guide groove section 3211. When the sliding part 3222 enters the anti-reverse groove section 3212 from the first guide groove section 3211, the elastic anti-reverse piece can be pushed away by the sliding part 3222. When the sliding part 3222 wants to return from the anti-reverse groove section 3212 to the first guide groove section 3211, the elastic anti-reverse piece will block the sliding part due to its own elastic restoring force.

[0142] This design, to a certain extent, facilitates the installation of the anti-reverse structure within the slide groove 321, thereby making the processing and manufacturing of the anti-reverse sub-assembly 32 easier.

[0143] In some embodiments, such as Figure 6 As shown, the first guide groove section 3211, the anti-reverse groove section 3212 and the second guide groove section 3213 form a closed loop groove section, and the anti-reverse groove section 3212 is recessed towards the inner side of the closed loop groove section.

[0144] With this configuration, after the sliding part 3222 enters the anti-reverse groove section 3212, the groove sidewall of the anti-reverse groove section 3212 can also restrict the movement path of the sliding part 3222, making it less likely that the sliding part 3222 will accidentally slide from the anti-reverse groove section 3212 to the first guide groove section 3211, thereby enhancing the stability of the anti-reverse function and ensuring that the latch 31 can be more reliably kept in the anti-reverse position.

[0145] In some embodiments, such as Figure 7 As shown, the bottom wall of the first guide groove section 3211 and the bottom wall of the second guide groove section 3213 are arranged in a stepped manner, and the bottom wall of the first guide groove section 3211 is located on the side of the bottom wall of the second guide groove section 3213 away from the opening of the slide groove 321.

[0146] In this way, after the sliding portion 3222 is reset to the first guide groove segment 3211 by the second guide groove segment 3213, in order to slide to the second guide groove segment 3213, the sliding portion 3222 is blocked by the stepped surface between the groove bottom wall of the first guide groove segment 3211 and the groove bottom wall of the second guide groove segment 3213. Because of the height difference of the stepped surface, the sliding portion 3222 cannot easily return in reverse, thereby effectively preventing the sliding portion 3222 from sliding from the first guide groove segment 3211 to the second guide groove segment 3213, ensuring that the lock catch 31 can be in the reverse stopping position when the filter screen assembly 2 is installed next time, and further ensuring that the next installation of the filter screen assembly 2 can be normally performed.

[0147] In some embodiments, as shown in Figure 5 The locking assembly 3 further includes a reset member 34, which is arranged in the installation space and connected between the lock catch 31 and the locking shell 33. The reset member 34 is used to drive the lock catch 31 to rotate in the reverse direction of the second direction (e.g., the A2 direction in Figure 5 ).

[0148] In this way, after the reverse stopping subassembly 32 removes the above-mentioned blocking of the lock catch 31, the reset member 34 drives the lock catch 31 to rotate in the reverse direction of the second direction, which can ensure that the lock catch 31 returns to the initial position in time after each operation. This can avoid affecting the installation operation of the filter screen assembly 2 next time due to the lock catch 31 being in an uncertain position, and even can avoid damage to the lock catch 31 or other related components.

[0149] In some embodiments, as shown in Figure 5 The reset member 34 is a tension spring.

[0150] In this way, first, the tension spring can provide stable reset force to drive the lock catch 31 to rotate in reverse by virtue of its elastic restoring force; second, the tension spring structure is simple and low in cost, which can simplify the structure of the locking assembly 3 and reduce the cost of the locking assembly 3; and finally, the tension spring has high reliability and long service life, which can enhance the reliability of the locking assembly 3 and prolong the service life of the locking assembly 3.

[0151] In some embodiments, the reset member 34 is a torsion spring.

[0152] In this way, because the torsion spring has good elastic stability, it can maintain relatively stable elastic restoring force for a long time during multiple uses. In this way, even after experiencing multiple cycles of disassembly and assembly of the filter screen assembly 2, the lock catch 31 can still be reliably reset, and the situation of suddenly changing the elastic force to affect the operation will not occur.

[0153] In some embodiments, as shown in Figure 8As shown, the filter assembly 2 comprises a mounting frame 23 and a filter screen 24, wherein the mounting frame 23 is sealingly fitted with the inner wall of the air inlet 11 through a sealing structure, and the filter screen 24 is arranged at the inner side of the mounting frame 23.

[0154] In this way, the mounting frame 23 is sealingly fitted with the inner wall of the air inlet 11 through the sealing structure, which can effectively prevent the air that has not been filtered by the filter screen 24 from entering the interior of the air conditioner indoor unit through the gap between the mounting frame 23 and the air inlet 11, thereby effectively preventing the oil fume from entering the interior of the air conditioner indoor unit, and facilitating the performance of the air conditioner indoor unit.

[0155] In some embodiments, the sealing structure comprises a sealing groove and a sealing protrusion, the sealing groove is for the sealing protrusion to be inserted into, and one of the sealing groove and the sealing protrusion is arranged on the inner wall of the air inlet 11 and the other is arranged on the mounting frame 23.

[0156] In this way, firstly, the sealing groove and the sealing protrusion are relatively simple in structure, and do not require complex sealing materials or high-cost sealing accessories, but mainly rely on their own structural shape to achieve the sealing function, so that the sealing structure can be simplified through the sealing groove and the sealing protrusion, and the processing and manufacturing of the sealing structure are facilitated.

[0157] Secondly, when the sealing protrusion is completely inserted into the sealing groove, it also means that the filter assembly 2 is accurately installed in place, so that the positioning of the installation of the filter assembly 2 is facilitated through the cooperation of the sealing groove and the sealing protrusion.

[0158] Finally, the cooperation of the sealing groove and the sealing protrusion not only achieves the sealing function, but also to some extent enhances the connection stability between the mounting frame 23 and the air inlet 11, thereby enhancing the stability of the installation of the filter assembly 2.

[0159] In some embodiments, the sealing structure comprises a sealing rubber strip mounted on the mounting frame 23 and the inner wall of the air inlet 11. When the filter assembly 2 is installed to the air inlet 11, the sealing rubber strip will be squeezed between the two, and the gap will be filled through the elastic deformation of the rubber strip itself, thereby achieving sealing.

[0160] In this way, the sealing effect of the sealing rubber strip is good, and can adapt to the size deviation between the mounting frame and the air inlet to some extent. Moreover, the installation of the sealing rubber strip is relatively simple, and only needs to be pasted at the appropriate position, and the cost is also relatively low. At the same time, the sealing rubber strip can also play a certain damping and buffering role, reducing the noise caused by vibration.

[0161] In some embodiments, the direction perpendicular to the first direction and parallel to the plane on which the filter screen 24 is located is a third direction (such as the X direction in FIGS. 1A and 1B). Figure 8 and Figure 11

[0162] As​Figure 9 As shown, the sealing groove comprises a first sealing groove segment 25 and a second sealing groove segment (not shown) extending in the first direction (e.g. Y direction in FIG. 1) along the length direction. Figure 9 As shown, the sealing protrusion comprises a first protrusion segment 12 and a second protrusion segment 13 extending in the first direction (e.g. Y direction in FIG. 1) along the length direction. Figure 11 As shown, the sealing groove comprises a first sealing groove segment 25 and a second sealing groove segment (not shown) extending in the first direction (e.g. Y direction in FIG. 1) along the length direction. Figure 11 As shown, the sealing protrusion comprises a first protrusion segment 12 and a second protrusion segment 13 extending in the first direction (e.g. Y direction in FIG. 1) along the length direction.

[0163] In this way, not only can the sealing be achieved in the third direction by the first protrusion segment 12, the second protrusion segment 13, the first sealing groove segment 25 and the second sealing groove segment, but also, since the length direction of the first sealing groove segment 25 and the second sealing groove segment extends in the first direction, the length direction of the first protrusion segment 12 and the second protrusion segment 13 extends in the first direction, and the filter screen assembly 2 is movably arranged in the first direction in the casing 1, when the filter screen assembly 2 is installed, the movement of the filter screen assembly 2 in the first direction can be guided by the guiding cooperation of the first protrusion segment 12 and the second protrusion segment 13 with the first sealing groove segment 25 and the second sealing groove segment in the first direction, so that the filter screen assembly 2 can be more accurately and quickly installed at the corresponding preset position of the air inlet 11.
