[0072] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0073] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0074] The indoor unit includes a frame, a panel, and a filter. The panel is movably connected to the front of the frame and can be opened and closed relative to the frame. The frame has an air outlet, and the filter is located between the frame and the panel, covering the air outlet. The panel is used to limit the movement of the filter. When the panel is opened for maintenance of the indoor unit, the filter loses its limiting function, causing the filter to loosen or accidentally detach from the housing assembly, affecting the stability of the filter assembly connection.

[0075] In view of this, the first aspect of this utility model provides an indoor unit 10 that can effectively improve the stability of the assembly and connection of the filter assembly 300. It is understood that the indoor unit 10 is used in an air conditioner. The following refers to... Figures 1 to 12 The indoor unit 10 of this application embodiment will be introduced. Specifically, the indoor unit 10 includes a housing assembly 100, a mounting bracket 200, and a filter assembly 300.

[0076] Reference Figures 1 to 4The housing assembly 100 can define a cavity 160, within which the heat exchanger, fan, and control module of the indoor unit 10 can be housed. Specifically, the housing assembly 100 includes a frame 110 and a panel 120. The frame 110 has an air inlet 111, which can be located on the upper side of the frame 110 (see reference). Figure 10 (Referring to the orientation of the indoor unit 10 in its installed state). The panel 120 is movably connected to the face frame 110, meaning the panel 120 can be opened or closed relative to the face frame 110 as needed. In some embodiments, the panel 120 can be rotatably connected to the face frame 110. In other embodiments, the panel 120 can be slidably connected to the face frame 110; this embodiment is described using the example of the panel 120 being rotatably connected to the face frame 110. Further, the panel 120 is movably connected to the front side of the face frame 110, referring to... Figure 9 Orientation: The front of the faceplate 110 can point to the right. It is understood that the housing assembly 100 also includes an air guide plate 140 and a chassis 150. Taking the orientation of the indoor unit 10 in the installed state as a reference, the air guide plate 140 can be located on the lower side of the faceplate 110, and the chassis 150 can be located on the lower side of the internal cavity 160 of the housing assembly 100.

[0077] Reference Figure 1 and Figure 2 A disassembly / removal opening 130 is formed between the panel 120 and the frame 110. The disassembly / removal opening 130 can be used to disassemble and assemble the filter assembly 300, meaning the filter assembly 300 can be directly inserted into or removed from the housing through the disassembly / removal opening 130. Specifically, in some embodiments, the disassembly / removal opening 130 can be formed jointly by the end side of the panel 120 and the frame 110. In other embodiments, the disassembly / removal opening 130 can also be formed jointly by the middle portion of the panel 120 and the frame 110. The specific location of the disassembly / removal opening 130 can be determined according to the actual situation.

[0078] Reference Figure 3 and Figure 11 The fixing bracket 200 is used to limit the position of the filter assembly 300 and is connected to the face frame 110. In some embodiments, the fixing bracket 200 can be integrally connected to the face frame 110. In other embodiments, the fixing bracket 200 can be detachably connected to the face frame 110. This application embodiment uses the detachable fixing bracket 200 and face frame 110 as an example for description. A guide channel 210 is formed between the fixing bracket 200 and the face frame 110. The guide channel 210 communicates with the disassembly port 130, that is, the filter assembly 300 can pass through the disassembly port 130 and pass through the guide channel 210 to achieve limited installation.

[0079] The following explains the specific connection between the guide channel 210 and the disassembly / removal port 130. In some embodiments, the fixing bracket 200 may be located on the side of the disassembly / removal port 130 facing the cavity 160, and the guide channel 210 may be positioned at a distance from the disassembly / removal port 130, with one end of the guide channel 210 communicating with the disassembly / removal port 130. In other embodiments, the fixing bracket 200 may be located on the side of the disassembly / removal port 130 away from the cavity 160, with one end of the guide channel 210 communicating with the disassembly / removal port 130. In other embodiments, the fixing bracket 200 may also at least partially pass through the disassembly / removal port 130, meaning the guide channel 210 also passes through the disassembly / removal port 130 but still communicates with it. The specific arrangement of the guide channel 210 may vary depending on the actual situation.

[0080] Reference Figure 5 , Figure 9 and Figure 10 The filter assembly 300 is used to filter dust, dirt, and other impurities from the air. The filter assembly 300 is movably connected to the face frame 110, facilitating disassembly for regular cleaning. Specifically, the filter assembly 300 can be slidably connected to the face frame 110. The filter assembly 300 can extend from the disassembly port 130 to the air inlet 111. When the air inlet 111 is located in a dead corner position such as the top side of the housing assembly 100, the filter assembly 300 can be easily disassembled and assembled directly from the bottom side of the housing assembly 100, improving disassembly and assembly efficiency.

[0081] Reference Figure 7 and Figure 8 The specific structure of the filter assembly 300 is described below. The filter assembly 300 includes a filter section 310 and a positioning section 320. The positioning section 320 is connected to the filter section 310 and can position the filter section 310 at its installation location. The filter section 310 covers at least a portion of the air inlet 111, and its specific coverage area can be determined according to actual conditions. It should be noted that the positioning section 320 can be a plate-like structure or a mesh-like structure; this embodiment uses a plate-like structure as an example for explanation. Furthermore, the positioning section 320 can be a plastic plate.

[0082] Reference Figure 1 , Figure 2 and Figure 10 The positioning part 320 can pass through the guide channel 210 and be exposed at the disassembly / removal port 130. The specific situation where the positioning part 320 is exposed at the disassembly / removal port 130 is explained below. In some embodiments, the positioning part 320 can pass through the disassembly / removal port 130. In other embodiments, the positioning part 320 can pass within the disassembly / removal port 130 but can be seen from within it. The specific arrangement of the positioning part 320 and the disassembly / removal port 130 can be determined according to the actual situation. This application embodiment uses the example of the positioning part 320 passing through the disassembly / removal port 130 for explanation.

[0083] When the filter assembly 300 needs to be disassembled, it can be driven to move relative to the face frame 110 until at least a portion of the filter section 310 passes through the disassembly port 130. It is understood that in some embodiments, the filter assembly 300 can be completely detached from the face frame 110. In other embodiments, the filter assembly 300 can only be partially detached from the face frame 110. Specifically, the portion of the filter assembly 300 covering the air inlet 111 can be pulled out from the face frame 110 like a drawer for cleaning. This application embodiment is described using the example of the filter assembly 300 being completely detached from the face frame 110.

[0084] In the technical solution of this utility model, the indoor unit 10 includes a housing assembly 100, a fixed bracket 200, and a filter assembly 300. The housing assembly 100 includes a front frame 110 and a panel 120. The panel 120 is movably connected to the front side of the front frame 110, and the front frame 110 is provided with an air inlet 111. The filter assembly 300 is movably connected to the front frame 110 and extends from the disassembly port 130 to the air inlet 111. The filter assembly 300 includes a filter part 310 and a positioning part 320 connected to each other. The filter part 310 covers at least part of the air inlet 111 to achieve filtration. In related technologies, the panel is used to limit the filter. When the panel is opened for maintenance of the indoor unit, the filter loses the limiting function of the panel, causing the filter to loosen or accidentally fall out of the housing assembly, affecting the stability of the filter assembly connection. In this design, the fixing bracket 200 is connected to the front frame 110, and a guide channel 210 is formed between the fixing bracket 200 and the front frame 110, connecting to the disassembly / removal port 130. The positioning part 320 of the filter assembly 300 passes through the guide channel 210 and protrudes from the disassembly / removal port 130. This means the fixing bracket 200 can continuously limit the position of the filter assembly 300, improving the stability of the filter assembly 300 assembly connection. This effectively prevents the filter assembly 300 from loosening or accidentally detaching from the housing assembly, and prevents dust from the filter assembly 300 from falling into the indoor unit 10. Furthermore, in this design, the panel 120 and the front frame 110 form the disassembly / removal port 130, allowing the filter assembly 300 to move relative to the front frame 110 until at least a portion of the filter part 310 passes through the disassembly / removal port 130. Therefore, this design allows for the disassembly / removal of the filter assembly 300 without opening the panel 120, improving the efficiency and convenience of disassembly / removal.

[0085] Reference Figure 2 and Figure 3The arrangement of the fixing bracket 200 is described below. In some embodiments, the fixing bracket 200 can be disposed between the panel 120 and the frame 110, that is, no matter where the panel 120 moves relative to the frame 110, the fixing bracket 200 can continuously limit the filter assembly 300, thereby ensuring the reliability of the assembly connection of the filter assembly 300. It should be noted that the fixing bracket 200 can be located inside the disassembly port 130, that is, the fixing bracket 200 can be located on the side of the disassembly port 130 facing the internal cavity 160 of the housing. In other embodiments, the fixing bracket 200 is located outside the disassembly port 130, that is, the fixing bracket 200 can be located on the side of the disassembly port 130 away from the internal cavity 160 of the housing. Furthermore, the guide channel 210 formed between the fixing bracket 200 and the frame 110 communicates with the disassembly port 130. It should be noted that one port of the guide channel 210 may communicate with the disassembly port 130. Furthermore, the positioning portion 320 of the filter assembly 300 may be exposed at the port of the guide channel 210 opposite to the disassembly / removal port 130. In other embodiments, the fixing bracket 200 may be located between the panel 120 and the frame 110. The fixing bracket 200 may pass through the disassembly / removal port 130, that is, the guide channel 210 formed by the fixing bracket 200 and the frame 110 may be arranged through the disassembly / removal port 130. The specific arrangement of the fixing bracket 200 may be determined according to the actual situation.

[0086] Reference Figures 1 to 4 The relative arrangement of panel 120, face frame 110, and fixing bracket 200 is described below. In some embodiments, fixing bracket 200 may be disposed inside the disassembly port 130. It can be understood that the inside of disassembly port 130 may be the side of disassembly port 130 facing the internal cavity 160 of the housing. Fixing bracket 200 may be disposed between panel 120 and face frame 110. Panel 120 may be movably connected to face frame 110. Specifically, when panel 120 is in the first position, panel 120 may cover fixing bracket 200, thereby preventing external foreign objects from entering the housing through guide channel 210 and other positions. It should be noted that panel 120 may cover the front side of face frame 110 while covering fixing bracket 200. When panel 120 is in the second position, panel 120 may open fixing bracket 200, and panel 120 may open its front side while opening fixing bracket 200. It is understood that the panel 120 can move relative to the frame 110 to switch from the first position to the second position. The position switching operation of the panel 120 in this solution is convenient and quick, making it easier for relevant personnel to inspect and maintain the internal components of the indoor unit 10.

[0087] Reference Figures 1 to 4The specific fixing configuration of panel 120 is described below. In some embodiments, panel 120 can be detachably connected to fixing bracket 200. In other embodiments, panel 120 can be detachably connected to face frame 110 without being connected to fixing bracket 200. In other embodiments, panel 120 can be detachably connected to both fixing bracket 200 and face frame 110 simultaneously. The specific fixing configuration of panel 120 can be determined according to the actual situation. This application embodiment takes the example of panel 120 being detachably connected to both fixing bracket 200 and face frame 110 simultaneously for illustration. This solution can effectively improve the stability of panel 120 assembly connection and effectively suppress accidental opening and closing of panel 120.

[0088] Reference Figure 3 The relative connections between panel 120, frame 110, and fixed bracket 200 are described below. In some embodiments, the upper end of panel 120 is movably connected to frame 110; specifically, the upper end of panel 120 can be rotatably or slidably connected to frame 110. It should be noted that the fixed bracket 200 can be located at the lower side between panel 120 and frame 110, or at the middle side between panel 120 and frame 110. This embodiment uses the example of the fixed bracket 200 being located at the lower side between panel 120 and frame 110 for illustration.

[0089] Reference Figures 3 to 6 The specific connection configuration between panel 120 and fixed bracket 200 is described below. In some embodiments, fixed bracket 200 is provided with a first slot 220, located on the side of fixed bracket 200 facing panel 120. Panel 120 is provided with a first engaging protrusion 121, located on the lower end of panel 120 facing fixed bracket 200. The first engaging protrusion 121 of panel 120 can extend into the first slot 220 of fixed bracket 200, and the two engage with each other. In other embodiments, fixed bracket 200 is provided with a first engaging protrusion 121, located on the side of fixed bracket 200 facing panel 120. Panel 120 is provided with a first slot 220, located on the side of panel 120 facing fixed bracket 200. The first engaging protrusion 121 of fixed bracket 200 can extend into the first slot 220 of panel 120, and the two engage with each other. The specific connection configuration between the fixed bracket 200 and the panel 120 can be determined according to the actual situation. It should be noted that the first slot 220 can be set as a single slot or multiple slots. This embodiment of the application is described using multiple first slots 220 as an example. Each first snap-fit ​​protrusion 121 can be adapted to the arrangement of each first slot 220.

[0090] The first snap-fit ​​protrusion 121 of this solution extends into the first snap-fit ​​groove 220 and the two snap-fit ​​each other, which can effectively improve the stability of the assembly connection between the fixed bracket 200 and the panel 120, and the assembly connection operation between the fixed bracket 200 and the panel 120 is convenient and quick.

[0091] Reference Figures 3 to 6 The specific connection configuration between the faceplate 110 and the fixing bracket 200 is described below. In some embodiments, the faceplate 110 is provided with a second slot 112, which is located on the side of the faceplate 110 facing the fixing bracket 200. The fixing bracket 200 is provided with a second engaging protrusion 230, which is located on the side of the fixing bracket 200 facing the faceplate 110. The second engaging protrusion 230 of the fixing bracket 200 can extend into the second slot 112 of the faceplate 110, and the two engage with each other. In other embodiments, the faceplate 110 is provided with a second engaging protrusion 230, which is located on the side of the faceplate 110 facing the fixing bracket 200. The fixing bracket 200 is provided with a second slot 112, which is located on the side of the fixing bracket 200 facing the faceplate 110. The second engaging protrusion 230 of the faceplate 110 can extend into the second slot 112 of the fixing bracket 200, and the two engage with each other. The specific connection configuration between the fixed bracket 200 and the face frame 110 can be determined according to the actual situation. It should be noted that the second slot 112 can be single or multiple; this embodiment uses multiple second slots 112 as an example. Each second snap-fit ​​protrusion 230 can be adapted to the arrangement of each second slot 112. In this solution, the second snap-fit ​​protrusion 230 extends into the second slot 112 and the two snap together, which effectively improves the stability of the assembly connection between the fixed bracket 200 and the face frame 110, and the assembly connection operation between the fixed bracket 200 and the face frame 110 is convenient and quick.

[0092] Reference Figure 3 In some embodiments, the panel 120 is provided with a third snap-fit ​​protrusion located on the side of the panel 120 facing the fixed bracket 200. A third snap-fit ​​groove 240 is recessed at a corresponding position on the side of the fixed bracket 200 opposite to the second snap-fit ​​protrusion 230. In this solution, the third snap-fit ​​protrusion of the panel 120 can extend into the third snap-fit ​​groove 240 of the fixed bracket 200, and the two snap-fit ​​together, thus ensuring the stability of the connection between the panel 120 and the fixed bracket 200. Furthermore, because the third snap-fit ​​groove 240 of the fixed bracket 200 and the second snap-fit ​​protrusion 230 are positioned opposite each other, the third snap-fit ​​groove 240 and the second snap-fit ​​protrusion 230 can be integrally formed. Therefore, this solution can improve the processing efficiency of the fixed bracket 200 and reduce processing costs.

[0093] In other embodiments, when the fixed bracket 200 has a second slot 112 on the side facing the face frame 110, and the face frame 110 has a second engaging protrusion 230 on the side facing the fixed bracket 200, and the second engaging protrusion 230 passes through and engages with the second slot 112, a third engaging protrusion can be formed at the corresponding position on the side of the fixed bracket 200 opposite to the second slot 112. The panel 120 has a third slot 240 on the side facing the fixed bracket 200, and the third engaging protrusion of the fixed bracket 200 can extend into the third slot 240 of the panel 120 and engage with each other. In other embodiments, the third slot 240 can also be spaced apart from the second engaging protrusion 230, that is, the positions of the third slot 240 and the second engaging protrusion 230 are not opposite to each other along the thickness direction of the fixed bracket 200.

[0094] Reference Figure 5 The specific configuration of the filter assembly 300 is described below. In some embodiments, the indoor unit 10 includes multiple filter assemblies 300. The specific number of filter assemblies 300 can be determined according to the actual situation. This embodiment of the application uses two filter assemblies 300 as an example for explanation. Each filter assembly 300 is movably connected to the face frame 110. It can be understood that the specific connection structure 3222 between each filter assembly 300 and the face frame 110 can be the same or different. This embodiment of the application uses the example of filter assemblies 300 having the same structure and being slidably connected to the face frame 110. This solution can improve the convenience of installing and removing the filter assembly 300. Furthermore, each filter assembly 300 can extend from the installation / removal port 130 to the air inlet 111, and each filter assembly 300 can jointly cover the air inlet 111, which can ensure the filtration effect of the filter assembly 300.

[0095] Reference Figure 1 and Figure 5 In some embodiments, the positioning portion 320 of each filter assembly 300 passes through the guide channel 210, meaning the fixing bracket 200 can simultaneously limit the positioning of each filter assembly 300, effectively preventing the filter assemblies from accidentally detaching from the indoor unit or becoming loose, and preventing dust on the filter assemblies 300 from falling into the indoor unit 10. Furthermore, the positioning portion 320 of each filter assembly 300 is exposed through the disassembly / removal port 130. Specifically, in some embodiments, each positioning portion 320 can extend through the disassembly / removal port 130. In other embodiments, each positioning portion 320 can be inserted into the disassembly / removal port 130 but is visible from it. In other embodiments, some positioning portions 320 can extend through the disassembly / removal port 130, and other positioning portions 320 can extend into the disassembly / removal port 130 but are visible from it. This application embodiment uses the example of each positioning portion 320 extending through the disassembly / removal port 130 for illustration.

[0096] In this solution, the indoor unit 10 uses multiple filter assemblies 300 to cover the air inlet 111, which makes it easy to select and replace a pair of filter assemblies 300 at a specific location according to actual needs. Compared with the solution that uses a single filter assembly 300 to cover the air inlet 111, the structural size of a single filter assembly 300 in this solution is smaller, which makes the structure of the filter part 310 more stable. This effectively reduces the possibility of the filter assembly 300 deforming significantly and causing dust to accidentally fall into the indoor unit 10.

[0097] The specific structure of the filter section 310 is described below. In some embodiments, the filter section 310 includes a support rib 311 and a filter screen 312, with the support rib 311 and the filter screen 312 connected to each other. Specifically, the support rib 311 can extend along the path from the disassembly port 130 to the air inlet 111. The extension length of the support rib 311 can be greater than the arrangement length of the filter screen 312, thus ensuring the support effect of the support rib 311 on the filter screen 312.

[0098] Reference Figure 4 The following describes the relative movable arrangement of the filter assembly 300 and the fixed bracket 200. The fixed bracket 200 is provided with a first guide protrusion 250, which is located on the side of the fixed bracket 200 facing the guide channel 210. It should be noted that the position of the first guide protrusion 250 corresponds to the support rib 311. During the process of the filter 312 extending out of the disassembly port 130, the support rib 311 remains in contact with the first guide protrusion 250. In some embodiments, the side of the support rib 311 facing the first guide protrusion 250 is also provided with a guide groove. The first guide protrusion 250 can pass through the guide groove and slide within it, thereby improving the stability of the filter part 310 sliding relative to the fixed bracket 200 and effectively suppressing the filter part 310 from changing track and thus undergoing significant deformation.

[0099] In this design, the filter 312 is extended from the disassembly port 130, and the supporting rib 311 remains in contact with the first guide protrusion 250. This prevents the filter 312 from touching the fixed bracket 200 during disassembly and assembly, reducing the risk of dust falling into the filter. Furthermore, since the supporting rib 311 extends along the path from the disassembly port 130 to the air inlet 111, the filter assembly can maintain cooperation with the fixed bracket 200 and move steadily during disassembly and assembly, effectively suppressing large vibrations of the filter 312 and further reducing the possibility of dust from the filter 312 falling into the indoor unit 10.

[0100] Reference Figure 7 and Figure 8The following describes the relative movable arrangement of the filter section 310 and the face frame 110. In some embodiments, the filter section 310 includes support ribs 311 and a filter screen 312 connected to each other. It is understood that multiple support ribs 311 can be provided, the filter screen 312 can be adapted to the arrangement of the support ribs 311, and the support ribs 311 can support the filter screen 312. The support ribs 311 extend along the path from the disassembly port 130 to the air inlet 111, and their specific extension length can be determined according to the actual situation.

[0101] Reference Figure 5 The face frame 110 is provided with a limiting rib 113, which supports the support rib 311 of the filter section 310. The limiting rib 113 is provided with a second guide protrusion 114, which is located on the side of the limiting rib 113 facing the support rib 311 and can abut against the support rib 311. It should be noted that the specific structure of the second guide protrusion 114 can be the same as or different from the first guide protrusion 250. In some embodiments, the side of the support rib 311 facing the second guide protrusion 114 is also provided with a guide groove, and the second guide protrusion 114 can pass through the guide groove and slide in the guide groove, which can improve the stability of the filter section 310 sliding relative to the face frame 110 and effectively suppress the filter section 310 from changing track and thus undergoing large deformation.

[0102] In this design, the second protrusion of the limiting rib 113 can abut against the supporting rib 311, which can prevent the filter screen 312 from touching the face frame 110 during disassembly and assembly, reducing the risk of dust falling. Furthermore, the supporting rib 311 extends along the path from the disassembly port 130 to the air inlet 111, so that the filter assembly can maintain cooperation with the face frame 110 and move continuously and smoothly during disassembly and assembly, effectively suppressing the filter screen 312 from vibrating significantly, and further reducing the possibility of dust on the filter screen 312 falling onto the indoor unit 10.

[0103] Reference Figures 7 to 10 The relative movable arrangement of the filter section 310 and the panel 120 is described below. In some embodiments, the filter section 310 includes a support rib 311 and a filter screen 312 connected to each other. The support rib 311 extends along a path from the disassembly port 130 to the air inlet 111. It is understood that the path from the disassembly port 130 to the air inlet 111 can be straight or curved. In this embodiment, a curved path from the disassembly port 130 to the air inlet 111 is used as an example for explanation.

[0104] Reference Figure 6The panel 120 is provided with a third guide protrusion 122, which can be located on the side of the panel 120 facing the support rib 311. It is understood that the specific structure of the third guide protrusion 122 can be the same as or different from the first guide protrusion 250. The third guide protrusion 122 can abut against the support rib 311. In some embodiments, the side of the support rib 311 facing the third guide protrusion 122 is also provided with a guide groove, through which the third guide protrusion 122 can pass and slide, thereby improving the stability of the filter section 310 sliding relative to the panel 120 and effectively suppressing the filter section 310 from changing track and thus undergoing significant deformation.

[0105] In this design, the third guide protrusion 122 of the panel 120 can abut against the support rib 311, which can prevent the filter screen 312 from touching the panel 120 during disassembly and assembly, reducing the risk of dust falling. Furthermore, the support rib 311 extends along the path from the disassembly port 130 to the air inlet 111, so that the filter assembly can maintain cooperation with the panel 120 and move continuously and smoothly during disassembly and assembly, effectively suppressing the filter screen 312 from vibrating significantly, and further reducing the possibility of dust on the filter screen 312 falling onto the indoor unit 10.

[0106] Reference Figures 7 to 11 The specific fixing arrangement of the positioning part 320 is described below. In some embodiments, the positioning part 320 can be detachably connected to the face frame 110. In other embodiments, the positioning part 320 can be detachably connected to the fixing bracket 200. In other embodiments, the positioning part 320 can be detachably connected to the panel 120, and the specific fixing position of the positioning part 320 can be determined according to the actual situation. Further, the filter part 310 can be detachably connected to the face frame 110 or detachably connected to the panel 120.

[0107] Reference Figure 11 The following describes the specific locking mechanism between the filter assembly 300 and the face frame 110. In some embodiments, the positioning part 320 of the filter assembly 300 includes an elastic arm 321. The face frame 110 is provided with an abutment groove 115, which is located on the side of the face frame 110 facing the elastic arm 321. One end of the elastic arm 321 can be engaged in the abutment groove 115 to prevent the filter assembly 300 from disengaging from the face frame 110, thus achieving locking. When it is necessary to disassemble the filter assembly 300, the elastic arm 321 can be forced to undergo elastic deformation, thereby disengaging the elastic arm 321 from the abutment groove 115 in the direction of extending out of the disassembly port 130, thus achieving disassembly. In this solution, the locking and disassembly operations of the positioning part 320 are convenient and quick, and the cooperation between the elastic arm 321 and the abutment groove 115 can ensure the stability of the assembly connection between the filter assembly 300 and the face frame 110, preventing the filter assembly 300 from becoming loose.

[0108] Reference Figure 11The specific structure of the abutment groove 115 is described below. In some embodiments, the abutment groove 115 has a supporting wall 116, which is located on the side of the abutment groove 115 near the disassembly port 130, and the supporting wall 116 is arranged at an angle. Specifically, the supporting wall 116 is arranged at an angle towards the positioning part 320 in a direction that gradually approaches the disassembly port 130. To facilitate description and understanding of the specific angle of inclination of the supporting wall 116, the disassembly port 130 is provided to have an axis 131 passing through it, and the angle α between the supporting wall 116 and the axis 131 of the disassembly port 130 satisfies: 20°≤α≤50°. For example, α can be 20°, 25°, 28°, 31°, 35°, 38°, 43°, 44°, 49°, or 50°, etc. The aforementioned inclined angle of the abutment groove 115 in this design can prevent the locking force of the abutment groove 115 on the elastic arm 321 from being too large, which would make it difficult for the filter assembly 300 to detach from the abutment groove 115 and make the disassembly of the filter assembly 300 inconvenient. At the same time, it can also prevent the locking force of the abutment groove 115 on the elastic arm from being too small, which would make the filter assembly 300 easily detach from the abutment groove 115 and affect the stability of the assembly of the filter assembly 300.

[0109] Reference Figures 7 to 12 The specific structure of the positioning part 320 is described below. In some embodiments, the positioning part 320 includes a positioning body 322 and a driving structure 323, with the driving structure 323 connected to the positioning body 322. The driving structure 323 is capable of acquiring a driving force to detach the filter assembly 300 from the faceplate 110. It is understood that this driving force can be provided by an operator. The driving structure 323 may be exposed in the detachment / removal port 130. It should be noted that in some embodiments, the driving structure 323 may extend through the detachment / removal port 130. In other embodiments, the driving structure 323 may also extend within the detachment / removal port 130, but may be viewed from within the detachment / removal port 130.

[0110] Reference Figure 12The specific cooperation arrangement between the positioning body 322 and the driving structure 323 is described below. The positioning body 322 is provided with a groove 3221, which can be adapted to the arrangement of the driving structure 323. In some embodiments, the driving structure 323 can be rotatably connected to the positioning body 322. In other embodiments, the driving structure 323 can be slidably connected to the positioning body 322. This application embodiment uses the rotatable connection between the driving structure 323 and the positioning body 322 as an example for explanation. The driving structure 323 has a first position and a second position relative to the positioning body 322. When in the first position, the driving structure 323 can extend out of the groove 3221, that is, the filter assembly 300 can be detached from the face frame 110 by the driving structure 323. When in the second position, the driving structure 323 can be accommodated in the groove 3221, that is, the situation where the filter assembly 300 is dislodged from the face frame 110 due to accidental contact with the driving structure 323 can be avoided. This solution can unlock the filter assembly 300 through the drive structure 323, thereby enabling the disassembly of the filter assembly 300. Disassembly does not require opening the panel 120, making the overall operation convenient and quick.

[0111] Reference Figure 7 and Figure 8 The specific cooperation arrangement between the positioning part 320 and the housing assembly 100 is described below. The positioning part 320 includes a positioning body 322 and a drive structure 323 connected to the positioning body 322. The drive structure 323 can obtain the driving force for mounting and dismounting the filter assembly 300 onto the face frame 110, and the drive structure 323 can be arranged exposed in the mounting / dismounting port 130. (Refer to...) Figure 8 The positioning body 322 includes multiple connecting structures 3222, and the specific number of connecting structures 3222 can be determined according to the actual situation. It should be noted that the specific structures of each connecting structure 3222 can be the same or different. This embodiment of the application uses two identical connecting structures 3222 as an example for illustration. Each connecting structure 3222 is used for detachable connection with the housing assembly 100. The maximum difference between the minimum distance between each connecting structure 3222 and the driving structure 323 is less than or equal to 20mm. For example, the maximum difference can be 20mm, 19.5mm, 17mm, 16.4mm, or 15mm, etc. The multiple connecting structures 3222 and the driving structure 323 in this solution adopt the above-mentioned positional layout, which can avoid the situation where the filter assembly 300 cannot be removed due to uneven locking force of the two connecting structures 3222 when the filter assembly 300 is disassembled from the face frame 110, thus ensuring the reliability of the disassembly and assembly of the filter assembly 300.

[0112] Reference Figures 1 to 8The specific cooperation arrangement of the positioning part 320, panel 120, face frame 110, and fixing bracket 200 is described below. In some embodiments, the fixing bracket 200 can be disposed between the panel 120 and the face frame 110, that is, no matter where the panel 120 moves relative to the face frame 110, the fixing bracket 200 can continuously limit the filter assembly 300, ensuring the reliability of the assembly connection of the filter assembly 300. It should be noted that the fixing bracket 200 can be located inside the disassembly port 130, that is, the fixing bracket 200 can be located on the side of the disassembly port 130 facing the internal cavity 160 of the housing.

[0113] Reference Figure 11 In some embodiments, the end of the positioning part 320 exposed in the disassembly / removal port 130 can abut against the end of the fixing bracket 200 facing the disassembly / removal port 130. Therefore, the fixing bracket 200 can limit the positioning part 320, preventing it from being completely inserted into the panel 120 and unable to be pulled out inside the face frame 110. In other embodiments, the face frame 110 has a step portion 117 at the disassembly / removal port 130, the step portion 117 including a step surface 1171, the step surface 1171 being located on the side of the step portion 117 facing the disassembly / removal port 130. The end of the positioning part 320 exposed in the disassembly / removal port 130 can abut against the step surface 1171, that is, the step portion 117 of the face frame 110 in this embodiment can limit the positioning part 320, preventing the positioning part 320 from being completely contained within the disassembly / removal port 130, thus preventing relevant personnel from directly operating the positioning part 320 and disassembling / removing the filter part 310, ensuring the reliability of the filter assembly 300 disassembly / removal.

[0114] Reference Figure 7 and Figure 8The specific structural configuration of the filter section 310 is described below. In some embodiments, the filter section 310 includes a support rib 311 and a filter screen 312. The support rib 311 can connect to and support the filter screen 312, effectively suppressing significant deformation of the filter screen 312 during assembly and disassembly. Further, the support rib 311 can extend along the path from the disassembly / reassembly port 130 to the air inlet 111. The specific extension length and direction of the support rib 311 can be determined according to actual conditions. It should be noted that the support rib 311 can be provided with multiple recesses 3111. The specific structure of each recess 3111 can be the same or different. This embodiment uses the example of identical specific structures for each recess 3111. The recesses 3111 are arranged at intervals along the extension direction of the support rib 311. It should be noted that the interval between two adjacent recesses 3111 can be uniform or non-uniform. This embodiment uses the example of a uniform interval between two adjacent recesses 3111. The support rib 311 of this design has multiple recesses 3111, which can save material of the support rib 311 and reduce the contact area between the support rib 311 and the face frame 110, the panel 120 and the fixed bracket 200, thereby reducing the overall sliding resistance of the filter assembly 300, so that the filter assembly 300 can be pulled out more smoothly and reduce the situation of dust falling due to vibration of the filter assembly 300.

[0115] Reference Figure 3 and Figure 4 The specific location of the air inlet 111 is described below. In some embodiments, the air inlet 111 may be located at the top of the face frame 110 (with the orientation of the indoor unit 10 in the installed state as a reference). In other embodiments, the air inlet 111 may also be located on the side of the face frame 110 along the lateral direction (with the orientation of the indoor unit 10 in the installed state as a reference). This embodiment of the application will be described with the air inlet 111 located at the top of the face frame 110 as an example.

[0116] Reference Figure 1 and Figure 2 The specific configuration of the disassembly port 130 is described below. In some embodiments, the disassembly port 130 may be located at the lower end of the panel 120 (with the orientation of the indoor unit 10 in the installed state as a reference). In other embodiments, the axis 131 of the disassembly port 130 may be arranged vertically. By adopting the above configuration of the disassembly port 130 in this solution, the difficulty of assembling and disassembling the filter assembly 300 can be reduced, and the efficiency of assembly and disassembly of the filter assembly 300 can be improved.

[0117] A second aspect of this utility model provides an air conditioner, including an indoor unit 10 and an outdoor unit as described in the above embodiment. The outdoor unit is connected to the indoor unit 10. In this design, a fixing bracket 200 is connected to a front frame 110, and a guide channel 210 is formed between the fixing bracket 200 and the front frame 110, communicating with a disassembly / removal opening 130. The positioning portion 320 of the filter assembly 300 passes through the guide channel 210 and protrudes from the disassembly / removal opening 130. This means the fixing bracket 200 can continuously limit the position of the filter assembly 300, improving the stability of the filter assembly 300 assembly connection. This effectively prevents the filter assembly 300 from loosening or accidentally detaching from the housing assembly, preventing dust from the filter assembly 300 from falling into the indoor unit 10. Furthermore, in this design, a disassembly / removal opening 130 is formed between the panel 120 and the front frame 110, allowing the filter assembly 300 to move relative to the front frame 110 until at least a portion of the filter portion 310 passes through the disassembly / removal opening 130. This solution allows for the disassembly and assembly of the filter assembly 300 without requiring the panel 120 to be opened, thus improving the efficiency and convenience of disassembly and assembly.

[0118] It should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this utility model, such directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. When a directional reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the directional reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0119] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0120] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
