Description

Technical Field

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

[0002] Currently, split-type air conditioners generally consist of a frame and a control panel that rotates on the frame. The control panel needs to be fastened to the frame during use, and must be opened to access and repair the components inside the frame during maintenance and cleaning. The electrical control box is typically located on the right side of the frame. This control box can interfere with the hinge on the control panel, requiring the hinge to be positioned to avoid the control box, thus placing the hinge a considerable distance from the right edge of the frame.

[0003] Panels are usually injection molded. Due to their long size, they are more prone to product deformation. The right corner of the panel is far from the pivot, which may cause the right corner to lift up when the panel is fastened, resulting in a large assembly gap with the frame, affecting the appearance and user experience. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides an air conditioning indoor unit.

[0005] This application provides an indoor unit for an air conditioner, comprising:

[0006] The frame body has an opening at its top and a receiving space, the receiving space being located at one end of the frame body along a first direction, and the opening having a slot formed along the first direction near the inner wall of the receiving space.

[0007] The panel has one edge along a second direction as a first edge and is rotatably connected to the frame body. A slot is provided near the first edge. The panel has a first elastic buckle along the edge along the first direction near the receiving space. The first elastic buckle includes a first elastic plate and a first protrusion protruding from the first elastic plate. The first elastic plate is configured to deform along the first direction, so that when the panel is fastened to the frame body, the first protrusion is engaged in the slot; or, when the panel rotates relative to the frame body, the first protrusion is disengaged from the slot.

[0008] Wherein, the first direction is the length direction of the main body of the frame, and the second direction is the width direction of the main body of the frame.

[0009] The air conditioner indoor unit provided in this application embodiment includes a frame body and a panel. The frame body has an internal space for installing an electrical control box. The first side of the panel is rotatably connected to the frame body. The opening is recessed along the first direction near the inner wall of the electrical control box in the space to form a slot. The slot is located near the first side. A first elastic buckle is provided on one edge of the panel along the first direction. The first elastic buckle is located at the corner of the panel near the first side to correspond with the slot. When the panel rotates relative to the frame body, the first elastic plate can be elastically deformed in the first direction, so that the first protrusion can be engaged and disengaged from the slot, which facilitates the switching of the panel between the closed and open states on the frame body. When the first protrusion engages with the slot along the first direction, the slot limits the first protrusion in the direction of rotation of the panel relative to the frame body, preventing the corners of the panel from lifting up; and the slot's limitation of the first protrusion in the direction perpendicular to the first direction makes it less likely for the first protrusion to fall out of the slot even if the panel is subjected to an impact perpendicular to the first direction, ensuring that the corners of the panel remain in close contact with the frame body, avoiding large assembly gaps between the panel and the frame body, and improving the aesthetics of the air conditioner indoor unit and the user experience.

The second elastic buckle is located at the end of the ear portion away from the panel body. The frame body is provided with two mating parts, and the two mating parts are correspondingly provided with the two second elastic buckles.

[0019] When the panel is fastened to the frame body, the two ears fit snugly against the frame body, the two second elastic buckles engage with the two mating parts, and the air outlet is exposed between the two ears.

[0020] In some embodiments, the second elastic buckle includes a second elastic plate and a second protrusion, the second protrusion protruding from the second elastic plate, and the mating part includes a snap-fit ​​protrusion disposed on the frame body. The two snap-fit ​​protrusions are disposed on both sides of the air outlet along the first direction. When the panel is fastened to the frame body, the second protrusion moves to the side of the snap-fit ​​protrusion facing the center of the frame body and abuts against the snap-fit ​​protrusion.

[0066] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0067] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0068] Reference Figures 1 to 35 As shown, this application provides an indoor air conditioner unit, including a frame body 1 and a panel 2. The top of the frame body 1 forms an opening 11 and has a receiving space, which is located at one end of the frame body 1 along a first direction. The opening 11 has a slot 12 formed on the inner wall of the receiving space along the first direction. The panel 2 has a first edge 20 on one side along a second direction and is rotatably connected to the frame body 1. The slot 12 is located near the first edge 20. The panel 2 has a first elastic buckle 21 on the side edge of the receiving space along the first direction. The first elastic buckle 21 includes a first elastic plate 211 and a first protrusion 212 protruding from the first elastic plate 211. The first elastic plate 211 is configured to deform along the first direction, so that when the panel 2 is fastened to the frame body 1, the first protrusion 212 is engaged in the slot 12; or, when the panel 2 rotates relative to the frame body 1, the first protrusion 212 is disengaged from the slot 12. The first direction is the length direction of the frame body 1, and the second direction is the width direction of the frame body 1.

[0069] Specifically, the indoor unit of the air conditioner is installed indoors, usually on the wall. The main frame 1 is the frame structure of the indoor unit. The interior of the main frame 1 is hollow, so that the internal space of the main frame 1 can be used as a housing space, allowing the motor, fan, and electrical control box 3 of the indoor unit to be installed in the housing space inside the main frame 1. When the main frame 1 is installed on the wall, the side of the main frame 1 away from the wall is the top of the main frame 1.

[0070] An opening 11 is formed on the top of the aforementioned frame body 1. The opening 11 communicates with the internal accommodating space of the frame body 1, allowing the motor, fan, and electrical control box 3 of the indoor air conditioning unit to be installed inside the frame body 1 through the opening 11. The length direction of the frame body 1 is a first direction, and the width direction of the frame body 1 is a second direction. The opening 11 can be extended along the first direction to increase the area of ​​the opening 11. The electrical control box 3 is located at one end of the opening 11 along the first direction, that is, the electrical control box 3 is located at one end of the accommodating space along the first direction and can be exposed at one end of the opening 11 along the first direction.

[0071] A crank or shaft can be optionally installed on the first side 20 of the aforementioned panel 2. The crank or shaft is rotatably connected to the frame body 1, allowing the panel 2 to rotate relative to the frame body 1. The first side 20 is located on the side of the opening 11 along the second direction, allowing the panel 2 to rotate relative to the frame body 1. When the panel 2 is attached to the frame body 1, the panel 2 covers the opening 11, and the panel 2 is in the closed position. When the panel 2 rotates away from the frame body 1, an angle is formed between the panel 2 and the frame body, exposing the opening 11 on the frame body 1, and the panel 2 is in the open position. When the panel 2 is in the closed position, it protects the motor, fan, and electrical control box 3 inside the frame body 1. When the panel 2 is in the open position, the opening 11 is exposed, facilitating maintenance of the motor, fan, and electrical control box 3 inside the frame body 1 through the opening 11.

[0072] Because the control box 3 is relatively large, and it is typically located at one end of the first opening 11 along the first direction, a portion of the first side 20 near the control box 3 along the first direction cannot accommodate a crank for connection to the frame body 1. The rotational connection between the crank and the frame body 1 provides a positioning effect for the shape of the panel 2. The distance between the crank and the corner of the first side 20 of the panel 2 near the control box 3 is relatively large, making it easy for the corner of the panel 2 near the control box 3 to lift up. When the panel 2 is in the closed position, the first elastic buckle 21 engages with the slot 12, ensuring that the corner of the panel 2 near the control box 3 and at the first side 20 fits snugly against the frame body 1, preventing the corner of the panel 2 from lifting up.

[0073] The aforementioned panel 2 is provided with a first elastic buckle 21 on the side of the panel 2 that is close to the receiving space in the first direction. The first elastic buckle 21 is provided on the side edge of the panel 2 that is close to the electrical control box 3 in the receiving space along the first direction. The first elastic buckle 21 is provided near the first edge 20 of the panel 2. So that after the panel 2 is fastened to the frame body 1, the first elastic buckle 21 and the slot 12 are arranged opposite to each other in the first direction, so that the first protrusion 212 can be inserted into the slot 12.

[0074] The panel 2 described above can optionally be equipped with a buckle. When the panel 2 is in the closed position, the buckle on the panel 2 engages with the edge of the opening 11, thus fastening the panel 2 to the frame body 1. Alternatively, a groove can be provided on the top of the frame body 1, and when the panel 2 is in the closed position, the buckle on the panel 2 engages with the groove on the top of the frame body 1. Alternatively, a protrusion can be provided on the top of the frame body 1, and a groove can be formed on the side of the panel 2 facing the frame body 1. When the panel 2 is in the closed position, the protrusion on the frame body 1 engages with the groove on the panel 2, thus fastening the panel 2 to the frame body 1.

[0075] The inner wall of the opening 11, near the inner wall of the control box 3, is recessed along the first direction to form a slot 12. The slot 12 is located near the first side 20. The opening 11 can be rectangular, and the slot 12 is located at the corner of the opening 11 near the control box 3 and the first side 20. A first elastic buckle 21 is provided on the side edge of the panel 2 near the first control box 3 along the first direction. The first elastic buckle 21 is located near the first side 20, so that when the panel 2 is in the closed position, the first elastic buckle 21 and the slot 12 are arranged opposite each other along the first direction.

[0076] The first elastic plate 211 can be extended along the axial direction of the opening 11, and the first protrusion 212 can be disposed on the side of the first elastic plate 211 facing the slot 12 in the first direction; when the panel 2 is in the closed position, the first elastic buckle 21 is located in the opening 11, that is, the first elastic plate 211 extends into the opening 11, and the first protrusion 212 can be inserted into the slot 12.

[0077] When panel 2 rotates from the closed position to the open position, panel 2 drives the first elastic buckle 21 to move. The first protrusion 212 abuts against the inner wall of the slot 12 away from the inside of the frame body 1. The inner wall of the slot 12 applies a force to the first protrusion 212 in the first direction away from the slot 12, causing the first elastic plate 211 to elastically deform in the first direction away from the slot 12, thereby causing the first protrusion 212 to move in the first direction away from the slot 12 and disengage from the slot 12.

[0078] When panel 2 moves from the open position to the closed position, the first protrusion 212 abuts against the edge of the opening 11. The edge of the opening 11 applies a force to the first protrusion 212 in a first direction away from the slot 12, causing the first elastic plate 211 to elastically deform in the first direction, thereby allowing the first protrusion 212 to enter the slot 12. After the first protrusion 212 enters the slot 12, the inner wall of the slot 12 limits the first protrusion 212, so that the position of panel 2 with the first elastic buckle 21 can fit against the frame body 1, preventing the corners of panel 2 from lifting up.

[0079] Panel 2 can rotate relative to the frame body 1 along the rotation axis in the first direction. Therefore, panel 2 has good stability relative to the frame body 1 in the first direction. Panel 2 has poor stability relative to the frame body 1 in the direction perpendicular to the first direction. When panel 2 is subjected to external impact, panel 2 is prone to deformation or slight displacement in the direction perpendicular to the first direction. The first protrusion 212 is inserted into the slot 12 along the first direction, so that the slot 12 can have a good limiting effect on the first protrusion 212 in the direction perpendicular to the first direction. When the panel 2 of the air conditioner indoor unit is subjected to an impact perpendicular to the first direction, the first protrusion 212 will not be dislodged from the slot 12, ensuring that the corners of panel 2 are attached to the frame body 1 and will not lift up. When the indoor unit of the air conditioner is installed on the wall, the side of the panel 2 closest to the ground along the second direction is easily hit. The force generated by the impact is mainly along the second direction. The first protrusion 212 is connected to the slot 12 along the first direction, so that the slot 12 has a good limiting effect on the first protrusion 212 in the second direction. When the panel 2 is hit along the second direction, the first protrusion 212 and the slot 12 can also maintain the connection.

[0080] When the first protrusion 212 is engaged with the slot 12, the distance between the side of the first protrusion 212 facing away from the first elastic plate 211 and the opening of the slot 12 can be less than or equal to 1.5 mm. This allows the first protrusion 212 and the slot 12 to engage to keep the corners of the panel 2 close to the frame body 1, and also allows the first protrusion 212 to disengage from the slot 12 when the user applies force to open the panel 2, so that the deformation of the first elastic plate 211 is small. This avoids the first elastic plate 211 from deforming too much and having too much resistance, so that the operation of opening the panel 2 will not have a jerky feeling.

[0081] In specific use, the air conditioner indoor unit provided in this embodiment has a frame body 1 mounted on a wall, and the first side 20 of the panel 2 connected to the frame body 1. The electrical control box 3 and other components are installed inside the frame body 1. When the air conditioner indoor unit is in normal use, the panel 2 is fastened to the frame body 1, covering the opening 11. The first protrusion 212 is engaged with the slot 12. When the air conditioner indoor unit needs maintenance, the panel 2 is rotated away from the frame body 1, and the first protrusion 212 disengages from the slot 12, so that the panel 2 is in an open state, and the opening 11 is exposed on the frame body 1. The user can then perform maintenance on the electrical control box 3 and other components inside the frame body 1 through the opening 11.

[0082] When panel 2 rotates from the closed position to the open position, panel 2 drives the first elastic buckle 21 to move. The first protrusion 212 abuts against the inner wall of the slot 12 away from the inside of the frame body 1. The inner wall of the slot 12 applies a force to the first protrusion 212 in the first direction away from the slot 12, causing the first elastic plate 211 to elastically deform in the first direction away from the slot 12, thereby causing the first protrusion 212 to move in the first direction away from the slot 12 and disengage from the slot 12.

[0083] When panel 2 moves from the open position to the closed position, the first protrusion 212 abuts against the edge of the opening 11. The edge of the opening 11 applies a force to the first protrusion 212 in a first direction away from the slot 12, causing the first elastic plate 211 to elastically deform in the first direction, thereby allowing the first protrusion 212 to enter the slot 12. After the first protrusion 212 enters the slot 12, the inner wall of the slot 12 limits the first protrusion 212, so that the position of panel 2 with the first elastic buckle 21 can fit against the frame body 1, preventing the corners of panel 2 from lifting up.

[0084] The air conditioner indoor unit provided in this application embodiment includes a frame body 1 and a panel 2. The frame body 1 has an internal space for installing an electrical control box 3. The first side 20 of the panel 2 is rotatably connected to the frame body 1. The opening 11 is recessed along the first direction near the inner wall of the electrical control box 3 in the receiving space to form a slot 12. The slot 12 is located near the first side 20. A first elastic buckle 21 is provided on one edge of the panel 2 along the first direction. The first elastic buckle 21 is located at the corner of the panel 2 near the first side 20 to correspond to the slot 12. When the panel 2 rotates relative to the frame body 1, the first elastic plate 211 can be elastically deformed in the first direction, so that the first protrusion 212 can be inserted into and removed from the slot 12, which facilitates the switching of the panel 2 between the state of being fastened and open on the frame body 1. When the first protrusion 212 engages with the slot 12 along the first direction, the slot 12 limits the first protrusion 212 in the rotation direction of the panel 2 relative to the frame body 1, preventing the corners of the panel 2 from lifting up; and the limiting of the first protrusion 212 by the slot 12 in the direction perpendicular to the first direction makes it less likely for the first protrusion 212 to fall out of the slot 12 even if the panel 2 is subjected to a collision perpendicular to the first direction, ensuring that the corners of the panel 2 remain in contact with the frame body 1, avoiding a large assembly gap between the panel 2 and the frame body 1, and improving the aesthetics of the air conditioner indoor unit and the user experience.

[0085] Reference Figures 1 to 14 As shown, in some embodiments, the top wall of the slot 12 in the axial direction of the opening 11 forms a first inclined surface 123, and the first protrusion 212 can be guided to disengage from the slot 12 via the first inclined surface 123. With this configuration, when the panel 2 rotates away from the frame body 1, and the first protrusion 212 disengages from the slot 12, it can slide along the first inclined surface 123. This allows a portion of the force exerted by the first elastic buckle 21 in the axial direction of the opening 11 to be converted into a force in a first direction via the first inclined surface 123, causing the first elastic plate 211 to deform in the first direction, thereby allowing the first protrusion 212 to disengage from the slot 12. The first inclined surface 123 guides the first protrusion 212 out of the slot 12, reducing the resistance to its disengagement.

[0086] Specifically, the side wall of the slot 12 closest to the panel 2 in the axial direction of the opening 11 is the top wall. The top wall can be inclined as a whole to form the first inclined surface 123, or a portion of the top wall away from the bottom of the slot 12 can be inclined to form the first inclined surface 123. The first inclined surface 123 is inclined towards the top of the frame body 1 in a first direction away from the bottom of the slot 12. When the panel 2 is rotated from the closed position to the open position, the first protrusion 212 abuts against the first inclined surface 123, and the first protrusion 212 moves along the first inclined surface 123 towards the top of the frame body 1. This causes the first inclined surface 123 to exert a force on the first protrusion 212 in the first direction and along the axial direction of the opening 11, causing the first protrusion 212 to slide along the first inclined surface 123 and disengage from the slot 12.

[0087] Reference Figure 12 and Figure 14 As shown, in some embodiments, the first protrusion 212 forms a second inclined surface 213 on its lower surface in the axial direction of the opening 11. The first protrusion 212 can be guided by the second inclined surface 213 to engage with the slot 12. With this configuration, the second inclined surface 213 can abut against the edge of the opening 11 when the panel 2 rotates toward the frame body 1, so that the edge of the opening 11 exerts an axial force on the first protrusion 212 in the opening 11. The axial force of the opening 11 can be partially converted into a force along the first direction through the second inclined surface 213, thereby deforming the first elastic plate 211 along the first direction so that the first protrusion 212 can engage with the slot 12, reducing the resistance of the first protrusion 212 engaging with the slot 12.

[0088] Specifically, when panel 2 is fastened to frame body 1, the surface of the first protrusion 212 facing the frame body 1 in the axial direction of opening 11 is the lower surface. The lower surface is inclined to form a second inclined surface 213. The second inclined surface 213 can be selected in the direction of the axial direction of opening 11 towards the inside of frame body 1. The second inclined surface 213 gradually moves away from the slot 12 in the first direction. When panel 2 rotates from the open position to the closed position, the second inclined surface 213 first abuts against the edge of opening 11. As panel 2 continues to rotate, the first elastic buckle 21 moves towards the inside of frame body 1. The second inclined surface 213 remains abutting against the edge of opening 11, so that the force of the first elastic buckle 21 along the axial direction of opening 11 is partially converted into a force moving away from the slot 12 in the first direction. This allows the first elastic plate 211 to deform in the first direction, so that the first protrusion 212 passes through the edge of opening 11 and is then inserted into the slot 12.

[0089] Reference Figure 8 , Figure 10 , Figure 12 and Figure 14As shown, in some embodiments, the frame body 1 includes a first connecting portion 121 and a second connecting portion 122 extending toward its center along a first direction. The first connecting portion 121 and the second connecting portion 122 are spaced apart vertically and form a groove 12 between them. The periphery of the first elastic plate 211 is provided with a baffle 215 extending toward a direction away from the center of the frame body 1. The first connecting portion 121 is positioned directly opposite the baffle 215, and when the first connecting portion 121 is subjected to external force against the baffle 215, a portion of the first protrusion 212 is located within the groove 12. With this configuration, when the frame body 1 or the panel 2 is impacted, the first connecting portion 121 collides with the baffle 215 instead of directly impacting the first elastic plate 211, thus preventing the first elastic plate 211 from breaking due to impact when the indoor unit of the air conditioner is impacted, and protecting the first elastic buckle 21 with the baffle 215.

[0090] Specifically, the first connecting portion 121 and the second connecting portion 122 can both be block structures. The first connecting portion 121 and the second connecting portion 122 are spaced apart along the axial direction of the opening 11, so that the space between the first connecting portion 121 and the second connecting portion 122 serves as a slot 12. The ends of the first connecting portion 121 and the second connecting portion 122 along the direction surrounding the opening 11 can be connected to each other, so that the slot 12 has two opposing inner walls in the direction surrounding the opening 11.

[0091] The first elastic plate 211 can be optionally provided with a baffle 215 along the direction surrounding the opening 11. That is, when the first protrusion 212 is engaged with the slot 12, the baffle 215 is provided on one or both sides of the first elastic plate 211 along the second direction. The baffle 215 extends toward the slot 12 along the second direction. Along the first direction, the baffle 215 extends to the area between the first elastic plate 211 and the side of the first protrusion 212 facing away from the first elastic plate 211. This allows the side of the first protrusion 212 facing away from the first elastic plate 211 to be inserted into the slot 12 and engaged with the slot 12 when the first connecting part 121 abuts against the baffle 215.

[0092] When panel 2 is fastened to frame body 1, the first connecting part 121 and the baffle 215 are spaced apart in the first direction. When panel 2 or frame body 1 is hit, the relative movement of panel 2 and frame body 1 in the first direction will cause the first connecting part 121 to contact the baffle 215. Frame body 1 applies force to baffle 215 without directly hitting the first elastic plate 211, so that baffle 215 has a protective function for the first elastic plate 211.

[0093] Reference Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 and Figure 14As shown, in some embodiments, a first reinforcing rib 214 connects the panel 2 and the first elastic plate 211, and the length of the first reinforcing rib 214 in a third direction is less than or equal to half the length of the first elastic plate 211 in a third direction, where the third direction is the thickness direction of the panel 2. This configuration improves the structural stability of the connection between the first elastic plate 211 and the panel 2, and the first reinforcing rib 214 does not affect the elastic deformation of the first elastic plate 211 along the first direction, allowing the first protrusion 212 to smoothly engage and disengage from the slot 12.

[0094] Specifically, the first reinforcing rib 214 can be a plate structure. A portion of the first elastic plate 211 near the panel is connected to the first reinforcing rib 214. The direction perpendicular to the side where the first elastic buckle 21 is located is the thickness direction of the panel 2. The first reinforcing rib 214 is connected to the first elastic plate 211 along the first direction and to the panel 2 along the third direction, thereby enabling the first reinforcing rib 214 to improve the structural stability of the first elastic plate 211.

[0095] While the aforementioned first reinforcing rib 214 improves the structural stability of the first elastic plate 211, it also affects the elastic deformation capability of the first elastic plate 211. Furthermore, the first elastic plate 211 is prone to breakage at the connection with the panel 2 when it deforms. Therefore, the length of the first reinforcing rib 214 in the third direction is now less than half of the length of the first elastic plate 211 in the third direction, so that the first elastic plate 211 is less likely to break at the connection with the panel 2 when it deforms. At the same time, it allows the first elastic plate 211 to deform smoothly along the first direction, so that the first protrusion 212 can be inserted into and removed from the slot 12.

[0096] Reference Figures 15 to 25 As shown, in some embodiments, the frame body 1 is also provided with an air outlet disposed on one side of the opening 11 along the second direction;

[0097] Panel 2 includes panel body 22 and two ears 23. One edge of panel body 22 is the first edge 20, and the other edge is connected to the two ears 23.

[0098] Each ear 23 is provided with a second elastic buckle 24 on the side facing the frame body 1. The second elastic buckle 24 is located at the end of the ear 23 away from the panel body 22. The frame body 1 is provided with two mating parts, and the two mating parts are correspondingly provided with the two second elastic buckles 24.

[0099] When panel 2 is fastened to frame body 1, the two ears 23 are in contact with frame body 1, and the two second elastic buckles 24 are engaged with the two mating parts, with the air outlet exposed between the two ears 23. This arrangement, with the second elastic buckles 24 engaging with the mating parts, allows the ears 23 to fit snugly against frame body 1, preventing the ears 23 from lifting up.

[0100] Specifically, the air outlet is located on one side of the opening 11 along the second direction. When the frame body 1 is connected to the wall, the air outlet is located on the bottom side of the opening 11. The air outlet is connected to the internal space of the frame body 1, so that the fan inside the frame body 1 can blow heated or cooled air out of the air conditioner indoor unit through the air outlet.

[0101] The panel body 22 can be a rectangular or other shaped panel structure. The ear 23 protrudes from one side of the panel body 22. The two ears 23 are spaced apart along the first direction so that the space between the two ears 23 can correspond to the air outlet and prevent the ears 23 from blocking the air outlet.

[0102] The aforementioned frame body 1 has mating parts on both sides of the air outlet along the first direction. The mating parts can be slots or protrusions, as long as the second elastic buckle 24 can engage with the mating parts.

[0103] The aforementioned second elastic buckle 24 is provided on the ear 23. The second elastic buckle 24 can be provided at the end of the ear 23 away from the panel body 22. Multiple buckle structures can be provided on the panel body 22. When the panel 2 is fastened to the frame body 1, the top of the panel body 22 is attached to the frame body 1 to cover the opening 11. The two ears 23 are attached to the area on both sides of the air outlet along the first direction of the frame body 1, and the second elastic buckle 24 is engaged with the mating part.

[0104] The aforementioned ear 23 is located on one side of the panel body 22. The panel 2 has a large overall area and is prone to bending during manufacturing. When the panel body 22 is attached to the top of the frame body 1, the ear 23 is prone to lifting due to a large gap between it and the frame body 1. The second elastic buckle 24 engages with the mating part, so that the ear 23 and the frame body 1 have a connection structure, thereby keeping the ear 23 attached to the frame body 1 and preventing the ear 23 from lifting.

[0105] The top side of the aforementioned frame body may include a flat part and a curved part. The curved part is connected to one side of the flat part along the second direction. The flat part has an opening 11, and the air outlet is provided on the curved part. The panel body 22 is provided corresponding to the flat part, and the ear is provided corresponding to the curved part. The ear is bent to fit the curved part. When the panel is fastened to the frame body, the panel body 22 fits against the flat part, and the ear 23 fits against the curved part.

[0106] Reference Figure 16 , Figure 17 , Figure 18 , Figure 23 and Figure 25 As shown, in some embodiments, the second elastic buckle 24 includes a second elastic plate 241 and a second protrusion 242. The second protrusion 242 protrudes from the second elastic plate 241. The mating part includes a snap-fit ​​protrusion 41 disposed on the frame body 1. The two snap-fit ​​protrusions 41 are disposed on both sides of the air outlet along the first direction. When the panel 2 is fastened to the frame body 1, the second protrusion 242 moves to the side of the snap-fit ​​protrusion 41 facing the center of the frame body 1 and abuts against the snap-fit ​​protrusion 41.

[0107] With this configuration, the panel 2 can rotate relative to the frame body 1, which will deform the second elastic plate 241, thereby allowing the second protrusion 242 to pass over the snap-fit ​​protrusion 41. The second protrusion 242 can move between the two sides of the snap-fit ​​protrusion 41 facing towards and away from the interior of the frame body 1, so as to conveniently complete the snap-fit ​​and disengagement operation between the second protrusion 242 and the snap-fit ​​protrusion 41.

[0108] Specifically, the second elastic plate 241 can be extended in a direction perpendicular to the panel body 22. The end of the second elastic plate 241 away from the ear 23 is provided with a second protrusion 242. The second protrusion 242 can be extended in the direction from the ear 23 toward the panel body 22 to protrude on the second elastic plate 241. Alternatively, the second protrusion 242 can be extended in the direction from the panel body 22 toward the ear 23 to protrude on the second elastic plate 241.

[0109] The aforementioned snap-fit ​​protrusion 41 may include a base plate and a protrusion. The base plate is disposed on the frame body 1 and extends in a direction away from the interior of the frame body 1. The protrusion protrudes from the base plate in a second direction. The second protrusion 242 abuts against the side of the protrusion facing the interior of the frame body 1, thereby snapping the second protrusion 242 with the snap-fit ​​protrusion 41 to keep the ear 23 in close contact with the frame body 1. Alternatively, a through hole may be provided on the frame body 1, with the edge of the through hole serving as the snap-fit ​​protrusion 41. The second protrusion 242 is inserted into the through hole and abuts against the side of the through hole near the interior of the frame body 1, thereby snapping the second protrusion 242 with the snap-fit ​​protrusion 41 to keep the ear 23 in close contact with the frame body 1.

[0110] When the panel 2 rotates from the open position to the closed position, the second protrusion 242 first abuts against the side of the locking protrusion 41 away from the interior of the frame body 1, and the second elastic plate 241 undergoes elastic deformation. As the panel 2 continues to move toward the frame body 1, the second protrusion 242 moves past the locking protrusion 41 and then to the side of the locking protrusion 41 facing the center of the frame body 1, so that the second protrusion 242 abuts against the side of the locking protrusion 41 facing the interior of the frame body 1, so that the locking protrusion 41 restricts the second protrusion 242 from moving away from the interior of the frame body 1, so that the ear 23 remains in a close fit with the frame body 1.

[0111] Reference Figure 16 , Figure 17 , Figure 18 , Figure 23 and Figure 25 As shown, in some embodiments, a third inclined surface 243 is formed on the side of the second protrusion 242 near the panel 2. The second protrusion 242 can be guided via the third inclined surface 243 to the side of the snap-fit ​​protrusion 41 facing away from the interior of the frame body 1. With this configuration, when the second protrusion 242 moves from the side of the snap-fit ​​protrusion 41 facing towards the interior of the frame body 1 to the side away from the interior of the frame body 1, the snap-fit ​​protrusion 41 and the third inclined surface 243 remain in contact. The third inclined surface 243 can guide the second protrusion 242 past the snap-fit ​​protrusion 41 to separate from the snap-fit ​​protrusion 41, reducing the resistance when the second elastic buckle 24 disengages from the snap-fit ​​protrusion 41.

[0112] Specifically, the second protrusion 242 is inclined to form a third inclined surface 243 on the side of the panel 2 near the extension direction of the second elastic plate 241. In the direction away from the second elastic plate 241, the third inclined surface 243 gradually moves away from the panel 2. When panel 2 rotates from the closed position to the open position, the third inclined surface 243 abuts against the locking protrusion 41. The locking protrusion 41 applies a force to the third inclined surface 243 along the direction of the second elastic plate 241. The force of the third inclined surface 243 along the direction of the second elastic plate 241 is partially converted into a force perpendicular to the direction of the second elastic plate 241, causing the second elastic plate 241 to elastically deform so that the second protrusion 242 can pass over the locking protrusion 41. During the process of the second protrusion 242 passing over the locking protrusion 41, the locking protrusion 41 abuts against the third inclined surface 243, that is, the locking protrusion 41 and the third inclined surface 243 slide relative to each other, so that the third inclined surface 243 guides the second protrusion 242 from the side of the locking protrusion 41 toward the inside of the frame body 1 to the side away from the inside of the frame body 1.

[0113] Alternatively, a mating ramp can be provided on the side of the snap-fit ​​protrusion 41 closest to the interior of the frame body 1. This ramp is inclined in the same direction as the third inclined surface 243, meaning that when the second protrusion 242 snaps into the snap-fit ​​protrusion 41, the ramp and the third inclined surface 243 are parallel and abut against each other. As the second protrusion 242 moves away from the interior of the frame body 1, the ramp and the third inclined surface 243 slide relative to each other, causing the second elastic plate 241 to elastically deform under their influence. This allows the second protrusion 242 to move past the snap-fit ​​protrusion 41 to the side of the snap-fit ​​protrusion 41 away from the interior of the frame body 1, further reducing friction when the second protrusion 242 disengages from the snap-fit ​​protrusion 41.

[0114] Reference Figure 16 , Figure 17 , Figure 18 , Figure 23 and Figure 25 As shown, in some embodiments, a fourth inclined surface 411 is formed on the side of the snap-fit ​​protrusion 41 facing away from the center of the frame body 1, and the second protrusion 242 can be guided via the fourth inclined surface 411 to the side of the snap-fit ​​protrusion 41 facing the interior of the frame body 1. With this configuration, when the second protrusion 242 snaps into the snap-fit ​​protrusion 41, the second protrusion 242 can slide along the fourth inclined surface 411, causing the second protrusion 242 to move past the snap-fit ​​protrusion 41 to the side of the snap-fit ​​protrusion 41 facing the interior of the frame body 1.

[0115] Specifically, when the second protrusion 242 is located on the side of the snap-fit ​​protrusion 41 close to the opening 11 along the second direction and abuts against the snap-fit ​​protrusion 41, the fourth inclined surface 411 gradually approaches the opening 11 along the direction toward the interior of the frame body 1; when the second protrusion 242 moves toward the center of the frame body 1 and abuts against the fourth inclined surface 411, the force of the second protrusion 242 toward the interior of the frame body 1 is partially converted into a force along the direction of the air outlet toward the opening 11 under the force of the fourth inclined surface 411, thereby causing the second elastic plate 241 to elastically deform along the direction of the air outlet toward the opening 11, so that the second protrusion 242 slides along the fourth inclined surface 411, and finally the second protrusion 242 slides along the fourth inclined surface 411 to the side of the snap-fit ​​protrusion 41 close to the interior of the frame body 1.

[0116] Alternatively, when the second protrusion 242 is located on the side of the snap-fit ​​protrusion 41 away from the opening 11 along the second direction and abuts against the snap-fit ​​protrusion 41, the fourth inclined surface 411 gradually moves away from the opening 11 along the direction toward the interior of the frame body 1; when the second protrusion 242 moves toward the center of the frame body 1, the second protrusion 242 moves along the fourth inclined surface 411, causing the second elastic plate 241 to elastically deform, so that the second protrusion 242 passes over the snap-fit ​​protrusion 41 and abuts against the side of the snap-fit ​​protrusion 41 closer to the frame body 1.

[0117] The height direction of the frame body 1 is perpendicular to both the first and second directions. The angle between the fourth inclined surface 411 and the length direction of the frame body 1 can be chosen to be 45°. This means the second protrusion 242 moves inward along the length direction of the frame body 1, at which point the second protrusion 242 abuts against the fourth inclined surface 411 and slides along it. The 45° angle of the fourth inclined surface 411 provides a good force component effect on the movement of the second protrusion 242 in the second direction, effectively driving the elastic deformation of the second elastic plate 241.

[0118] Reference Figure 16 and Figure 18 As shown, in some embodiments, a second reinforcing rib 244 is connected between the second elastic plate 241 and the panel 2. This arrangement enhances the structural strength between the second elastic plate 241 and the panel 2, thereby improving the stability of the second elastic plate 241 mounted on the panel 2.

[0119] Specifically, the second reinforcing rib 244 is connected between the second elastic plate 241 and the panel 2 near the panel 2, thereby improving the strength of the second elastic plate 241. The dimension of the second reinforcing rib 244 in the length direction of the second elastic plate 241 can be selected to be less than half the length dimension of the second elastic plate 241, so as to avoid the second reinforcing rib 244 affecting the elastic deformation of the second elastic plate 241.

[0120] Reference Figures 26 to 35 As shown, in some embodiments, the frame body 1 is provided with a receiving groove 13 at at least one edge along the first direction, the opening 11 and the receiving groove 13 are arranged along the first direction, the support rod 14 is rotatably arranged in the receiving groove 13, the panel 2 is provided with an abutment portion 25, and when the panel 2 is opened relative to the frame body 1, one end of the support rod 14 rotates out of the receiving groove 13 and abuts against the abutment portion.

[0121] With this configuration, after the panel 2 is opened onto the frame body 1, the support rod 14 can be supported between the frame body 1 and the panel 2, keeping the panel 2 in the open state. The user can inspect and repair the components inside the frame body 1 through the opening 11 without holding the panel 2.

[0122] Specifically, the frame body 1 may be provided with a receiving groove 13, which is located on the side of the opening 11 away from the electrical control box 3. Alternatively, the frame body 1 may be provided with two receiving grooves 13, which are respectively located on both sides of the opening 11 along the first direction.

[0123] The aforementioned support rod 14 can be a straight rod structure. One end of the support rod 14 is rotatably connected to the receiving groove 13. The support rod 14 rotates toward the receiving groove 13 to be housed inside the receiving groove 13. The support rod 14 rotates away from the receiving groove 13 to be turned out of the receiving groove 13 and exposed on the outside of the frame body 1. The abutting part 25 of the panel 2 abuts against the end of the support rod 14 away from the receiving groove 13, so that the panel 2, the frame body 1 and the support rod 14 form a triangular structure, thereby keeping the panel 2 in an open state under the support of the support rod 14.

[0124] The aforementioned abutment 25 can be a groove on the frame body 1, with one end of the support rod 14 abutting inside the groove, so that the abutment between the support rod 14 and the panel 2 remains stable. Alternatively, a protrusion can be provided on the frame body 1 as the abutment 25, with the support rod 14 abutting on the side of the protrusion near the first side 20, or the surface of the protrusion can be provided with a concave arc surface, with the support rod 14 abutting on the arc surface, so that the abutment between the support rod 14 and the panel 2 remains stable.

[0125] After the indoor unit of the air conditioner is installed on the wall, the first side 20 of the panel 2 is located on the side of the opening 11 away from the ground. The panel 2 rotates upward to open onto the frame body 1. The weight of the panel 2 itself will drive the panel 2 to rotate toward the frame body 1. When the user opens the panel 2 to inspect the components inside the frame body 1, they need to hold the panel 2 with their hand to keep it open, which makes the inspection operation inconvenient for the user. The support rod 14 supports the panel 2 between the panel 2 and the frame body 1, so that the panel 2 can be kept open, making it convenient for the user to inspect the components inside the frame body 1.

[0126] Reference Figures 27 to 32 As shown, in some embodiments, both the receiving groove 13 and the support rod 14 are arranged along a second direction. One end of the support rod 14 along the second direction is provided with a rotating shaft 141, and the receiving groove 13 is provided with a rotating groove 131. The rotating shaft 141 is rotatably placed in the rotating groove 131. With this arrangement, the movable insertion of the rotating shaft 141 and the rotating groove 131 allows the support rod 14 to rotate around the axis of the rotating shaft 141 along the first direction. The support rod 14 is arranged along the second direction so that after rotating out of the receiving groove 13, the support rod 14 can face the panel 2, thus restricting the movement of the support rod 14 in the first direction. This prevents the support rod 14 from disengaging from the abutment part 25 when it is impacted along the first direction of the indoor unit of the air conditioner, thereby improving the stability when the support rod 14 abuts the abutment part 25.

[0127] Specifically, both the receiving groove 13 and the support rod 14 are arranged along the second direction, which can make reasonable use of the area of ​​the frame body 1 at the edge of the opening 11 along the first direction. The end of the support rod 14 near the first side 20 along the second direction is provided with a rotating shaft 141, which is movably inserted into the rotating groove 131; of course, it is also possible to choose an end of the support rod 14 away from the first side 20 along the second direction to provide a rotating shaft 141, which is movably inserted into the rotating groove 131.

[0128] The aforementioned rotating groove 131 is provided on the inner wall of the receiving groove 13 along the first direction, so that after the rotating shaft 141 is rotatably connected to the rotating groove 131, the support rod 14 can rotate around the rotating shaft 141.

[0129] The aforementioned rotating shaft 141 can be optionally disposed on both sides of the support rod 14 along the first direction, and the rotating groove 131 is disposed on the opposite side grooves of the receiving groove 13 along the first direction. The two rotating shafts 141 are coaxially disposed along the first direction, and the two rotating grooves 131 are opposite to each other along the first direction. The two rotating shafts 141 are respectively inserted into the two rotating grooves 131 so that the support rod 14 is rotatably connected in the receiving groove 13.

[0130] Reference Figures 29 to 31 As shown, in some embodiments, the surface of the rotating shaft 141 facing the receiving groove 13 is provided with an assembly inclined surface 142, through which the rotating shaft 141 can be guided into the rotating groove 131. With this configuration, when the support rod 14 is installed in the receiving groove 13, the assembly inclined surface 142 can abut against the opening of the receiving groove 13, causing the opening of the receiving groove 13 and the rotating shaft 141 to elastically deform, allowing the support rod 14 and the rotating shaft 141 to enter the receiving groove 13. This allows the rotating shaft 141 to be inserted into the rotating groove 131 on the side wall of the receiving groove 13, reducing the resistance to the movable insertion of the rotating shaft 141 into the rotating groove 131.

[0131] Specifically, when the support rod 14 is parallel to the bottom of the receiving groove 13, the rotating shaft 141 is provided with an assembly inclined surface 142 on the side facing the bottom of the receiving groove 13. The assembly inclined surface 142 gradually moves away from the receiving groove 13 in a first direction away from the support rod 14. When the support rod 14 is installed in the receiving groove 13, the support rod 14 moves towards the receiving groove 13 while maintaining a state parallel to the bottom of the receiving groove 13. The assembly inclined surface 142 abuts against the edge of the groove opening of the receiving groove 13, and the assembly inclined surface 142 slides relative to the edge of the groove opening of the receiving groove 13. The rotating shaft 141 and the edge of the groove opening of the receiving groove 13 undergo elastic deformation, thereby allowing the rotating shaft 141 to enter the receiving groove 13 and enter the rotating groove 131 on the side wall of the receiving groove 13.

[0132] Reference Figures 29 to 31As shown, in some embodiments, ribs 132 are provided on both side walls of the receiving groove 13 along the first direction. When the support rod 14 is in the receiving groove 13, the ribs 132 abut against the support rod 14. With this arrangement, the ribs 132 can keep the support rod 14 stable when it is in the receiving groove 13.

[0133] Specifically, the rib 132 is a raised structure provided on the inner wall of the receiving groove 13. The two ribs 132 abut against the two sides of the support rod 14 along the first direction. The friction between the ribs 132 and the support rod 14 enables the support rod 14 to remain stable in the receiving groove 13.

[0134] Reference Figure 31 , Figure 32 , Figure 33 and Figure 35 As shown, in some embodiments, the length of the receiving groove 13 along the second direction is greater than the length of the support rod along the second direction, and an operating inclined surface 143 is provided at the end of the support rod 14 away from the pivot 141. When the support rod 14 is in the receiving groove 13, the operating inclined surface 143 is inclined in the direction away from the pivot 141 in the second direction toward the grass away from the receiving groove 13, thereby forming an operating space between the operating inclined surface 143 and the bottom of the receiving groove 13. With this arrangement, there is a gap between the support rod 14 and the end of the receiving groove 13 in the second direction, and the user can insert his finger into the operating space through the gap to facilitate applying a force away from the bottom of the receiving groove 13 to the support rod 14, making it convenient for the user to rotate the support rod 14 out of the receiving groove 13 to abut against the abutment part 25.

[0135] Reference Figure 26 , Figure 34 and Figure 35 As shown, in some embodiments, the panel 2 is provided with a hinge 26, which is rotatably connected to the frame body 1, and an abutment portion 25 is integrally formed on one side of the hinge 26. With this arrangement, the abutment portion 25 and the hinge 26 are integrally formed, reducing the area on the panel 2 for the abutment portion 25 and for rotatably connecting with the frame body 1.

[0136] Specifically, one end of the hinge 26 is connected to the frame body 1, and the other end is connected to the panel 2. The connection point between the hinge 26 and the panel 2 can be configured with a protrusion as an abutment 25, extending to the side of the hinge 26 parallel to the panel 2, so that the support rod 14 abuts against the intersection of the protrusion and the hinge. Alternatively, one end of the hinge 26 can be connected to the frame body 1, and the other end can have a base. The base is larger than the hinge 26, and the base is connected to the panel 2, serving as the abutment 25, with the support rod 14 abutting against the intersection of the base and the panel 2.

[0137] Reference Figure 26 , Figure 34 and Figure 35 As shown, the abutment portion 25 has an indentation on the side opposite to the panel 2 to form an arc-shaped surface, and the support rod 14 abuts against the arc-shaped surface. The support rod 14 is limited within the arc-shaped surface, so that the weight of the panel 2 itself limits the support rod 14 within the arc-shaped surface, thereby improving the stability of the abutment between the support rod 14 and the panel 2.

[0138] The first type of air conditioner indoor unit, for example Figures 1 to 14 As shown, the panel 2 is provided with a first elastic buckle 21, and the opening 11 is provided with a slot 12.

[0139] The second embodiment of the air conditioner indoor unit is as follows: Figures 15 to 25 As shown, panel 2 includes panel body 22 and ear part 23. The ear part 23 is provided with a second elastic buckle 24, and the frame body 1 is provided with a mating part.

[0140] The third embodiment of the air conditioner indoor unit is as follows: Figures 26 to 35 As shown, the frame body 1 is provided with a receiving groove 13 and a support rod 14, and the panel 2 is provided with an abutment part 25. When the panel 2 is opened on the frame body 1, the support rod 14 abuts against the abutment part 25.

[0141] In practical use, the air conditioner indoor unit provided in this application has its frame body 1 installed on the wall. During normal use, the panel 2 is fastened to the frame body 1, the panel body 22 covers the opening 11, the ear portion 23 is fitted against the frame body 1, the support rod 14 is located in the receiving groove 13 and abuts against the protruding rib 132, the first elastic buckle 21 is engaged with the groove 12, and the second elastic buckle 24 is engaged with the engaging protrusion 41. When the panel 2 is opened onto the frame body 1, the first elastic buckle 21 disengages from the groove 12, the second elastic buckle 24 disengages from the engaging protrusion 41, and the end of the support rod 14 away from the first side 20 rotates out of the receiving groove 13 and abuts against the abutment portion 25, thus supporting the panel 2 and keeping it open. The user can then inspect the components and electrical control box 3 inside the frame body 1 through the opening 11.

[0142] When panel 2 rotates from the closed position to the open position, panel 2 drives the first elastic buckle 21 to move, the first protrusion 212 abuts against the first inclined surface 123, the first protrusion 212 slides along the first inclined surface 123, causing the first elastic plate 211 to elastically deform in the first direction away from the slot 12, and the first protrusion 212 disengages from the slot 12; the third inclined surface 243 of the second protrusion 242 abuts against the mating inclined surface of the locking protrusion 41, the second protrusion 242 moves away from the interior of the frame body 1, the third inclined surface 243 slides relative to the mating inclined surface, causing the second elastic plate 241 to elastically deform in the direction away from the locking protrusion 41, and the second protrusion 242 moves past the locking protrusion 41 to the side of the locking protrusion 41 facing away from the interior of the frame body 1.

[0143] When panel 2 moves from the open position to the closed position, the second inclined surface 213 of the first protrusion 212 abuts against the edge of the opening 11. The edge of the opening 11 exerts a force on the first protrusion 212 in a first direction away from the slot 12 through the second inclined surface 213. The second inclined surface 213 causes the first elastic plate 211 to elastically deform in the first direction away from the slot 12, and the first protrusion 212 enters the slot 12 and engages with it. The second protrusion 242 abuts against the fourth inclined surface 411 and slides along the fourth inclined surface 411 towards the frame body 1, causing the second elastic plate 241 to elastically deform in a direction away from the engaging protrusion 41, so that the second protrusion 242 moves past the engaging protrusion 41 to the side of the engaging protrusion 41 facing the inside of the frame body 1, and abuts against the side of the engaging protrusion 41 facing the inside of the frame body 1. Panel body 22 and ear 23 are both attached to frame body 1.
