[0052] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-12 Specific embodiments of this utility model will be described in detail.

[0053] In this utility model, the terms "connection" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure.

[0054] In this utility model, the terms "inner", "outer", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0055] This utility model embodiment provides an air conditioner cover structure, see attached drawing. Figure 1 The cover structure 10 includes a body 110 and side plates 120. The side plates 120 are connected to opposite sides of the body 110 and form a U-shaped structure. The cover structure 10 is configured such that the cover and / or side plates 120 can be detachably connected to the middle frame 20 to cover or expose the pipe connection space of the middle frame 20. It should be noted that when the air conditioner needs to be mounted on the wall for pipe connection, the cover structure 10 is removed to fully expose the pipe connection space, facilitating direct pipe connection or replacement. After the pipe connection or replacement is completed, the cover structure 10 is installed on the middle frame 20 to cover the pipe connection space of the middle frame 20.

[0056] Compared with the existing technology that requires manual support of the air conditioner and another worker to connect the pipes, the air conditioner cover structure provided in this embodiment of the utility model, by setting a cover structure 10 that is detachably connected to the middle frame 20, can expose the pipe connection space, making it convenient for the installation worker to connect or replace the pipes; it eliminates the need for manual support of the air conditioner, thereby reducing the labor intensity of the workers; one worker can also complete the pipe connection, thereby saving labor costs.

[0057] In this embodiment of the utility model, the method by which the body 110 and the middle frame 20 are detachably connected is not limited. It can be a snap-fit ​​connection, a connection through fasteners, or a magnetic connection, as detailed below:

[0058] In the first embodiment, see Appendix Figure 1 and Figure 2 The inner wall surface of the body 110 is provided with a first buckle 130. There are multiple first buckles 130 and they are spaced apart along a first direction. The first buckles 130 are used to engage with the corresponding position of the middle frame 20. The first direction is the length direction of the body 110. With this setting, the buckle connection is convenient and quick to install and remove.

[0059] In the second embodiment, the main body 110 and the middle frame 20 are connected by fasteners. This configuration improves the stability of the main body 110 during installation.

[0060] See appendix Figure 3 , Figure 5 and Figure 6 In the first embodiment described above, the first buckle 130 includes a snap-fit ​​portion 131, the bottom end of which is fixed to the inner wall surface of the body 110, and the top end of which is provided with a first hook 134. The middle frame 20 is provided with a first snap-fit ​​hole 210 at a corresponding position. A cantilever 220 is fixed at one end of the first snap-fit ​​hole 210 along the second direction. Along the length direction of the cantilever 220 and pointing towards the free end of the cantilever 220, the distance between the cantilever 220 and the outer surface of the middle frame 20 gradually increases. A second hook 221 is provided at the free end of the cantilever 220. The first hook 134 can pass through the first snap-fit ​​hole 210 and snap with the second hook 221 to restrict the movement of the body 110 relative to the middle frame 20 in the opposite direction of the second direction. The second direction is the installation direction of the body 110. It should be noted that the cantilever 220 is capable of deformation. When the main body 110 is disassembled in the opposite direction of the second direction, the second hook 221 can move away from the first hook 134 under the force of the first hook 134, so that the first hook 134 disengages from the second hook 221. This configuration achieves the snap-fit ​​connection between the main body 110 and the middle frame 20.

[0061] See appendix Figure 5 and Figure 6In the first embodiment described above, the first buckle 130 further includes a limiting part 132, which is disposed opposite to the engaging part 131 along a third direction. The bottom end of the limiting part 132 is fixed to the inner wall surface of the body 110, and the first hook 134 is located on the side of the engaging part 131 away from the limiting part 132. The first hook 134, the second hook 221, and the limiting part 132 are configured such that the limiting part 132 can abut against the inner wall surface of the first engaging hole 210, and the first hook 134 can engage with the second hook 221, thereby restricting the movement of the body 110 relative to the middle frame 20 along a third direction; wherein, the third direction is the width direction of the body 110. With this configuration, the first hook 134 engages with the second hook 221, and at the same time, the limiting part 132 abuts against the inner wall surface of the first engaging hole 210, thereby restricting the movement of the body 110 relative to the middle frame 20 along a third direction.

[0062] See appendix Figure 5 and Figure 6 In the first embodiment described above, the top of the limiting portion 132 has a chamfered portion 135 on the side away from the snap-fit ​​portion 131. The chamfered portion 135 is configured such that: if the body 110 is installed along the second direction, the chamfered portion 135 provides a guide for the first snap-fit ​​hole 210 to be inserted into the first snap-fit ​​hole; or, if the body 110 is disassembled in the opposite direction of the second direction, the chamfered portion 135 can move along the side of the inner wall surface of the first snap-fit ​​hole 210 that abuts against the limiting portion 132, and the second snap hook 221 can move in a direction away from the first snap hook 134, so that the first snap hook 134 disengages from the second snap hook 221. With this configuration, the top of the limiting part 132 is provided with a chamfered part 135, so that when the first buckle 130 is inserted into the first snap-fit ​​hole 210, there is a gap between the chamfered part 135 and the inner wall surface of the first snap-fit ​​hole 210. Thus, when the body 110 is disassembled in the opposite direction of the second direction, after the limiting part 132 passes through the first snap-fit ​​hole 210, the limiting part 132 can move in the third direction and close to the upper wall surface of the first snap-fit ​​hole 210, so that the first hook 134 disengages from the second hook 221, thereby facilitating the removal of the body 110 from the middle frame 20.

[0063] See appendix Figure 5 and Figure 6 In the first embodiment described above, the first buckle 130 further includes a connecting portion 133. The bottom end of the connecting portion 133 is fixed to the inner wall surface of the body 110, and the connecting portion 133 is connected to the limiting portion 132 and the engaging portion 131. The connecting portion 133 protrudes from the surface of the engaging portion 131 and is located below the first hook 134. The end of the connecting portion 133 away from the limiting portion 132 can abut against the engaging hole. With this configuration, the connecting portion 133 can enhance the structural strength of the first buckle 130.

[0064] In this embodiment of the utility model, see Figure 5 and Figure 6The inner wall surface of the main body 110 may also be provided with a second buckle 140. There are multiple second buckles 140, which are spaced apart along a first direction. The second buckles 140 are used to engage with the corresponding positions of the middle frame 20. The first direction is the length direction of the main body 110. This arrangement realizes the buckle connection between the main body 110 and the middle frame 20.

[0065] In this embodiment of the utility model, see Figure 3 , Figure 5 and Figure 6 The inner wall surface of the body 110 may be provided with the aforementioned first buckle 130 and second buckle 140. The first buckle 130 and the second buckle 140 are respectively located near the opposite edge of the body 110 along a third direction. Multiple first buckles 130 are spaced apart along the first direction, and multiple second buckles 140 are spaced apart along the first direction. This arrangement achieves a stable connection between the body 110 and the middle frame 20.

[0066] In this embodiment of the utility model, see appendix. Figure 5 and Figure 6 The second latch 140 includes a latching arm 141, the bottom end of which is fixed to the inner wall of the body 110, and the top end of which has a bent portion 142. The middle frame 20 has a second latching hole 230 at a corresponding position. The bottom wall of the second latching hole 230 is provided with a latching piece 231. There is a gap between the latching piece 231 and the second latching hole 230. The latching piece 231 can deform along a second direction, wherein the second direction is the installation direction of the body 110. The latching arm 141 is configured such that it can pass through the second latching hole 230 and the bent portion 142 can abut against the inner surface of the latching piece 231, thereby restricting the movement of the body 110 relative to the middle frame 20 in the opposite direction of the second direction.

[0067] In this embodiment of the utility model, see appendix. Figures 7-9 The side panel 120 has a snap-fit ​​structure 121 along its edge, which is used to snap into the corresponding position on the side of the middle frame 20. This configuration enables the side panel 120 to snap into the side of the middle frame 20.

[0068] In this embodiment of the utility model, see appendix. Figures 7-9 The edge of the side panel 120 is provided with a first limiting piece 124. The first limiting piece 124 is used to abut against the inner wall of the middle frame 20 to restrict the movement of the side panel 120 along a first direction, wherein the first direction is the length direction of the body 110.

[0069] In this embodiment of the utility model, see appendix. Figure 9The middle frame 20 has an inwardly bent first flange 240 along its edge; the snap-fit ​​structure 121 includes a connecting arm 122 and a slot 123. One end of the connecting arm 122 is fixed to the side plate 120, and the other end has a slot 123. The opening of the slot 123 faces the outer wall surface of the side plate 120, and the slot 123 can snap onto the opposite side wall surface of the first flange 240. With this configuration, by pressing the side plate 120 in the first direction, the snap-fit ​​structure 121 deforms, thereby causing the slot 123 to disengage from the first flange 240, which is simple to operate; and when the slot 123 snaps onto the opposite side wall surface of the first flange 240, a locking effect can be achieved.

[0070] In this embodiment of the utility model, see appendix. Figure 9 The middle frame 20 has an inwardly bent first flange 240 along its edge; the side panel 120 has a protruding first limiting piece 124 along its edge, which can abut against the first flange 240. This configuration achieves the limitation of the side panel 120 along a third direction.

[0071] In this embodiment of the utility model, see appendix. Figure 7 and Figure 11 One of the inner wall surface of the side panel 120 and the side wall surface of the middle frame 20 is provided with a guide groove 250, and the other is provided with a guide strip 125. The guide groove 250 can cooperate with the guide strip 125. The length direction of the guide groove 250 extends approximately along a second direction, which is the installation direction of the body 110. This arrangement provides guidance for the installation of the cover structure 10.

[0072] In this embodiment of the invention, the cover plate structure 10 is integrally injection molded. This design simplifies the manufacturing process.

[0073] In this embodiment of the utility model, the thickness of the cover plate structure 10 is between 3-5mm.

[0074] In this embodiment of the present invention, a reinforcing structure 150 is provided at the edge near the body 110. The structure of the reinforcing structure 150 is not limited, and the specific details are as follows:

[0075] For example, see Appendix Figure 12 The reinforcing structure 150 includes a first folded edge 151 and a second folded edge 152. The first folded edge 151 protrudes from the inner wall surface of the body 110, and the second folded edge 152 is connected to the first folded edge 151. The body 110, the first folded edge 151, and the second folded edge 152 enclose a U-shaped space. This configuration improves the structural rigidity of the body 110 and reduces or even prevents deformation of the body 110.

[0076] For example, the reinforcing structure 150 is a reinforcing rib (not shown in the figure), which protrudes from the inner wall surface of the body 110 and extends along a first direction, which is the length direction of the body 110. This configuration increases the structural rigidity of the body 110 and reduces or even avoids deformation of the body 110.

[0077] For example, the reinforcing structure 150 is a second flange (not shown in the figure), which is formed by bending inward along the edge of the body 110. This configuration increases the structural rigidity of the body 110 and reduces or even prevents deformation of the body 110.

[0078] In this embodiment of the utility model, see appendix. Figure 7 and Figure 11 The inner wall of the side panel 120 may be provided with a protrusion 126, and the side wall of the middle frame 20 may be provided with a first elastic structure 270. The first elastic structure 270 can deform along the first direction, and the protrusion 126 can abut against the first elastic structure 270. This arrangement can prevent the side panel 120 from not being able to fit tightly against the side wall of the middle frame 20 when the body 110 is too long along the first direction.

[0079] In this embodiment of the utility model, see appendix. Figure 7 and Figure 11 The first elastic structure 270 is a tongue 271. The side wall of the middle frame 20 has an opening 260, and the axis of the opening 260 is along the first direction. One end of the tongue 271 is fixed to one side wall of the opening 260. There is a gap between the tongue 271 and the other side wall of the opening 260. The tongue 271 can be bent and deformed along the first direction.

[0080] In this embodiment of the utility model, the structure of the protrusion 126 is not limited, and is as follows: For example, see the attached drawing. Figure 7 The protrusion 126 is a tab, and there are two tabs that are spaced apart along a third direction. Reinforcing ribs are provided between the tabs, wherein the third direction is the width direction of the body 110; or, for example, the protrusion 126 is a block.

[0081] In this embodiment of the utility model, see appendix. Figure 7 The tongue 271 is provided with a limiting strip 272, and the side wall of the protrusion 126 can abut against the side wall of the limiting strip 272 to restrict the movement of the body 110 in the opposite direction of the second direction, wherein the second direction is the installation direction of the body 110.

[0082] In addition to the protrusion 126 on the inner wall of the side panel 120 and the first elastic structure 270 on the side wall of the middle frame 20, in this embodiment of the invention, the inner wall of the side panel 120 may also be provided with a second elastic structure (not shown in the figure). The second elastic structure is capable of deformation along a first direction and can abut against the side wall of the middle frame 20; wherein, the first direction is the length direction of the body 110. This arrangement can prevent the side panel 120 from failing to fit tightly against the side wall of the middle frame 20 when the body 110 is too long along the first direction.

[0083] The disassembly and assembly principle of the air conditioner cover structure provided in this embodiment of the utility model is as follows:

[0084] When the indoor unit of the air conditioner needs to be mounted on the wall and requires pipe connection, follow the first direction (e.g., ...). Figure 1 Pressing the side plate 120 inward in the X direction (as shown) causes the side plates on opposite sides of the body 110 to be recessed, thereby disengaging the snap-fit ​​structure 121 from the inwardly bent first flange 240 at the edge of the middle frame 20; then, along the second direction (as shown) Figure 1 A force is applied to the cover plate structure in the opposite direction (as shown in the Y direction), thereby causing the first latch 130 and the second latch 140 located on the body 110 to disengage from the first latching hole 210 and the second latching hole 230 of the middle frame 20, respectively. Specifically, along the second direction (as shown in the Y direction)... Figure 1 A force is applied to the cover structure in the opposite direction to the Y direction (as shown). The first hook 131 applies a force to the second hook 221 in the opposite direction to the second direction. The cantilever 220 swings in the YZ plane, causing the second hook 221 to move in the third direction (as shown). Figure 6 The first latch 131 gradually disengages from the second latch 221 as it moves in the opposite direction (as shown in the Z direction), thereby causing the first latch 130 to move relative to the first latching hole 210 along the second direction (as shown in the Z direction). Figure 1 When moving in the opposite direction (as shown in the Y direction), because the end of the limiting part 132 away from the body 110 has a chamfered part 135, the first buckle 130 can move relative to the first snap-fit ​​hole 210 in a third direction (such as the Y direction). Figure 6 The movement (in the Z direction as shown) promotes the first hook 131 to disengage from the second hook 22 until the cover plate structure is completely removed, so as to expose the pipe connection space of the middle frame 20, making it convenient for workers to connect or replace pipes.

[0085] After the air conditioner indoor unit's piping is connected, place the cover plate structure on the front side of the middle frame 20, along the second direction (e.g., Figure 1A force is applied to the cover plate structure in the Y direction (as shown). The guide strip 125 of the side plate 120 cooperates with the guide groove 250 of the middle frame 20 to provide guidance for the installation of the cover plate structure. When the end of the guide strip 125 abuts against the inner wall of the guide groove 250, the snap-fit ​​structure 121 snaps into the inwardly bent first flange 240 at the edge of the middle frame 20. Along the second direction (as shown) Figure 1 A force is applied to the body 110 in the Y direction (as shown), causing the first buckle 110 and the second buckle 140 located on the body 110 to engage with the first engagement hole 210 and the second engagement hole 230 of the middle frame 20, thereby installing the cover plate structure on the middle frame 20.

[0086] The second aspect of this utility model provides an indoor unit for an air conditioner, see appendix. Figure 1 The indoor unit of the air conditioner includes a middle frame 20 and the aforementioned air conditioner cover structure. The middle frame 20 has an air outlet 280 and a pipe connection space. The cover structure 10 is detachably connected to the middle frame 20 and located below the air outlet 280 to cover the pipe connection space.

[0087] In this embodiment of the utility model, see appendix. Figure 9 The edge of the middle frame 20 has a first flange 240, and the first flange 240 is provided with a second limiting piece 241, which can abut against the inner wall surface of the side panel 120.

[0088] The air conditioner indoor unit provided in this embodiment includes the above-mentioned air conditioner cover structure and has all the advantages of the above-mentioned air conditioner cover structure, which will not be repeated here.

[0089] While the present invention has been disclosed above, it is not limited thereto.
