In addition, the air conditioner indoor unit is hung on a wall, and when the air conditioner indoor unit is maintained later, the electric appliance cover plate directly falls after the screws are loosened, which causes the electric appliance cover plate to be damaged or scratched. CONTENT OF THE UTILITY MODEL

[0003] An air conditioner indoor unit is provided in the embodiments of the present application, which comprises:

[0004] a face frame provided with an opening and an elastic buckle; and

[0005] an electric appliance cover plate comprising a cover plate body made of a fireproof material, wherein the elastic modulus of the cover plate body is lower than the elastic modulus of the face frame, the cover plate body is provided with a buckle matching part, and the elastic buckle is matched with the buckle matching part to enable the electric appliance cover plate to be clamped to the face frame and cover the opening.

[0006] In some example embodiments, the elastic buckle comprises a first elastic buckle, and the buckle matching part comprises a buckle groove arranged on a first side of the cover plate body, and the first elastic buckle is clamped in the buckle groove.

[0007] In some example embodiments, the first elastic buckle comprises a first elastic arm and a first buckle part, the first elastic arm is connected with the face frame, and the first buckle part is arranged on the first elastic arm and protrudes towards the inner side of the opening.

[0008] The buckle groove comprises a first groove wall arranged to be pressed against the first buckle part in the process of clamping the first elastic buckle into the buckle groove, and at least one of the first buckle part and the first groove wall is provided with a first guide slope for guiding in the process of clamping the first buckle part into the buckle groove.

[0009] In some example embodiments, the first groove wall is provided with a second guide slope for guiding in the process of separating the first buckle part from the buckle groove.

[0010] In some example embodiments, the elastic buckle further comprises a second elastic buckle, and the first elastic buckle and the second elastic buckle are located on opposite sides of the opening.

[0011] The snap-fit part further comprises a buckle position part arranged on the second side of the cover plate body, the second side of the cover plate body is opposite to the first side, the second elastic buckle is snap-fit with the buckle position part.

[0012] In some example embodiments, the second elastic buckle comprises a second elastic arm and a second buckle part, the second elastic arm is connected with the face frame, and the second buckle part is arranged on the second elastic arm and protrudes towards the inner side of the opening.

[0013] The edge part of the cover plate body near the second side forms the buckle position part, and the second buckle part is provided with a third guide slope for guiding during snap-fit of the second buckle part with the buckle position part.

[0014] In some example embodiments, the second buckle part is provided with a fourth guide slope for guiding during disengagement of the second buckle part from the buckle position part, and the third guide slope and the fourth guide slope gradually approach along the protruding direction of the second buckle part.

[0015] In some example embodiments, the third side of the cover plate body is provided with a handle part, and the third side of the cover plate body is adjacent to the first side and the second side.

[0016] In some example embodiments, the handle part is arranged at the middle part of the third side of the cover plate body; and / or

[0017] The first side and the second side of the cover plate body are respectively the upper side and the lower side, and the third side of the cover plate body is the left side or the right side.

[0018] In some example embodiments, the face frame and the appliance cover plate are detachably fixed by fasteners.

[0019] The embodiments of the present application further provide an air conditioner, which comprises the indoor unit of the air conditioner as described in any of the above embodiments.

[0020] In this embodiment of the air conditioner indoor unit, the front frame and the electrical cover can be snapped together using a snap-fit ​​structure (elastic snap and snap-fit ​​mating part). The cover body of the electrical cover is made of fire-resistant material, and the elastic modulus of the cover body is lower than that of the front frame, meaning the elastic deformation capacity of the cover body is lower than that of the front frame. Therefore, the elastic snap is placed on the easily elastically deformable front frame, and the snap-fit ​​mating part is placed on the less elastically deformable cover body. When the elastic snap and the snap-fit ​​mating part snap together, the elastic deformation of the elastic snap achieves the snap-fit ​​engagement, thus snapping the front frame and the electrical cover together. Furthermore, placing the elastic snap on the easily elastically deformable front frame and the snap-fit ​​mating part on the less elastically deformable cover body facilitates the integral molding of the elastic snap and the snap-fit ​​mating part on the front frame and the cover body, respectively.

[0021] The front panel and electrical cover can be fixed in place by snap-fit ​​connections, and can also be further secured detachably with fasteners. This design prevents the electrical cover from falling directly off the front panel and being scratched after the fasteners are removed during later maintenance of electrical components. Furthermore, when installing the electrical cover after production or maintenance, the snap-fit ​​structure prevents it from being pushed up by electrical wires (such as motor wires), eliminating the need for workers to hold the cover down with one hand while installing fasteners with the other, thus improving assembly efficiency.

[0022] Other features and advantages of this application will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the application. Other advantages of this application can be realized and obtained by means of the embodiments described in the description and the accompanying drawings. Attached Figure Description

In addition, various modifications and changes can be made within the scope of protection of the appended claims.​​

[0050] Moreover, in describing representative embodiments, the specification can have presented the method and / or process as a particular sequence of steps. However, to the extent that the method or process depends on the particular order of steps, this description should not be construed as limiting since other steps can be performed in other sequences and / or omitted from the method or process.

Furthermore, the claims should not be limited to the steps of the method and / or process in the order in which they are written. Other sequences of steps can be performed in other orders and still be within the spirit and scope of the application.

[0051] The embodiments of the present application provide an air conditioner indoor unit, as shown in the drawings, comprising a face frame 1 and an electrical cover plate 2, the face frame 1 is provided with an opening 11 and an elastic buckle; the electrical cover plate 2 comprises a cover plate body 21 made of fireproof material, and the elastic modulus of the cover plate body 21 is lower than that of the face frame 1, the cover plate body 21 is provided with a buckle matching part, and the elastic buckle is matched with the buckle matching part to enable the electrical cover plate 2 to be clamped to the face frame 1 and cover the opening 11. Figures 1-22 In the air conditioner indoor unit, the face frame 1 can be provided with the opening 11 facing forward, and the electrical cover plate 2 can cover the opening 11 to protect the safety of the electrical components inside the air conditioner indoor unit, prevent external dust, moisture and other impurities from entering and affecting the normal operation of the equipment, and also play a decorative role of beautiful appearance and neatness. The electrical cover plate 2 can be detachable to facilitate the maintenance and replacement of the electrical components.

[0052] The face frame 1 and the electrical cover plate 2 can be clamped through the clamping structure (the elastic buckle and the buckle matching part), wherein the cover plate body 21 of the electrical cover plate 2 is made of fireproof material (such as fireproof plastic), and the elastic modulus of the cover plate body 21 is lower than that of the face frame 1, i.e. the elastic deformation capability of the cover plate body 21 is lower than that of the face frame 1, therefore, the elastic buckle is arranged on the face frame 1 which is easy to elastically deform, and the buckle matching part is arranged on the cover plate body 21 which is not easy to elastically deform, so that when the elastic buckle and the buckle matching part are clamped, the clamping and matching of the elastic buckle and the buckle matching part are realized through the elastic deformation of the elastic buckle, to clamp the face frame 1 and the electrical cover plate 2. In addition, arranging the elastic buckle on the face frame 1 which is easy to elastically deform and arranging the buckle matching part on the cover plate body 21 which is not easy to elastically deform facilitates the elastic buckle and the buckle matching part to be integrally formed on the face frame 1 and the cover plate body 21 respectively.

[0053]

[0054] ​The face frame 1 and the appliance cover plate 2 are fixed by clamping, and the face frame 1 and the appliance cover plate 2 can be further detachably fixed by fasteners. In this way, when the appliance components are repaired later, after the fasteners are removed, the clamping structure can prevent the appliance cover plate 2 from directly falling off the face frame 1 and being scratched; when the appliance cover plate 2 is installed after production or repair, since the appliance cover plate 2 is fixed by the clamping structure, the appliance cover plate 2 will not be pushed up by the wires (such as motor wires), so the staff does not need to hold the appliance cover plate 2 with one hand and install the fasteners with the other hand, thereby improving the assembly efficiency.

[0055] In some example embodiments, the face frame 1 and the appliance cover plate 2 are detachably fixed by fasteners. The fasteners include fastening screws. The appliance cover plate 2 is provided with fixing holes 25 (as shown in Figures 17-19 ).

[0056] The face frame 1 and the appliance cover plate 2 are not only connected by clamping through the elastic buckles and the buckle fitting portions, but also connected by the fastening screws, so that the fixing between the face frame 1 and the appliance cover plate 2 is more secure, the appliance cover plate 2 is detachable and easy to disassemble, and problems such as falling and scratching of the appliance cover plate 2 when the fastening screws are loosened are avoided, and the appliance cover plate 2 is prevented from being pushed up by the motor wires, which facilitates the staff to tighten the fastening screws and improves the production efficiency.

[0057] In some example embodiments, as shown in Figures 4-5 , Figures 8-9 , Figures 13-14 , Figure 18 , Figures 20-22 , the elastic buckle includes a first elastic buckle 12, and the buckle fitting portion includes a buckle groove 22 provided on the first side of the cover plate body 21, and the first elastic buckle 12 is clamped in the buckle groove 22.

[0058] The face frame 1 is provided with the first elastic buckle 12, and the first side of the cover plate body 21 is provided with the buckle groove 22, and the first elastic buckle 12 can be elastically deformed to realize clamping with the buckle groove 22. Through the cooperation of the first elastic buckle 12 and the buckle groove 22, the clamping connection of the appliance cover plate 2 and the face frame 1 is realized.

[0059] In some example embodiments, as shown in Figure 5 , Figures 8-9 , Figures 13-14 , the first elastic buckle 12 includes a first elastic arm 121 and a first buckle portion 122, the first elastic arm 121 is connected with the face frame 1 and can be elastically deformed, and the first buckle portion 122 is provided on the first elastic arm 121 and protrudes towards the inside of the opening 11.

[0060] As shown in Figure 18 , Figures 20-22As shown, the buckle groove 22 comprises a first groove wall 221 which is arranged to be pressed by the first buckle portion 122 during the buckling of the first elastic buckle 12 to the buckle groove 22. Under the pressing force between the first groove wall 221 of the buckle groove 22 and the first buckle portion 122 of the first elastic buckle 12, the first elastic arm 121 is elastically deformed, so that the first buckle portion 122 can pass the first groove wall 221 and enter the buckle groove 22, thereby realizing the buckling of the first elastic buckle 12 to the buckle groove 22.

[0061] At least one of the first buckle portion 122 and the first groove wall 221 is provided with a first guide inclined surface which guides the first buckle portion 122 during the buckling of the first buckle portion 122 to the buckle groove 22. Specifically, as shown in Figure 5 、 Figure 9 、 Figure 14 、 Figure 18 、 Figures 20-22 The first buckle portion 122 can be provided with a first guide inclined surface I 123, and the first groove wall 221 of the buckle groove 22 can be provided with a first guide inclined surface II 222. The first guide inclined surface I 123 and the first guide inclined surface II 222 can be inclined planes or curved surfaces, and can guide the first buckle portion 122 to buckle into the buckle groove 22 during the buckling, thereby facilitating the installation of the appliance cover plate 2.

[0062] It should be understood that the first guide inclined surface I 123 and the first guide inclined surface II 222 can be provided simultaneously, or only one of them can be provided.

[0063] In some exemplary embodiments, as shown in Figure 5 、 Figure 18 、 Figures 20-22 The first groove wall 221 is provided with a second guide inclined surface 223 which guides the first buckle portion 122 during the unbuckling of the first buckle portion 122 from the buckle groove 22.

[0064] The first groove wall 221 of the buckle groove 22 is provided with a second guide inclined surface 223 which can be an inclined plane or a curved surface, and can guide the first buckle portion 122 to be unbuckled from the buckle groove 22 during the unbuckling, thereby facilitating the disassembly of the appliance cover plate 2 for maintenance, replacement, etc. of the appliance elements.

[0065] It should be understood that the second guide inclined surface can only be provided on the first groove wall 221 of the buckle groove 22; or the second guide inclined surface which guides the first buckle portion 122 during the unbuckling of the first buckle portion 122 from the buckle groove 22 can only be provided on the first buckle portion 122; or the second guide inclined surface can be provided on both the first groove wall 221 of the buckle groove 22 and the first buckle portion 122.

[0066] In some exemplary embodiments, as shown in Figures 6-7 、 Figures 10-11 ,Figures 15-19 As shown, the elastic buckle further comprises a second elastic buckle 13, and the first elastic buckle 12 and the second elastic buckle 13 are located on opposite sides of the opening 11; correspondingly, the buckle matching part further comprises a buckle position part 23 arranged on a second side of the cover plate body 21, the second side of the cover plate body 21 is opposite to the first side, and the second elastic buckle 13 is in clamping cooperation with the buckle position part 23. Wherein, the first side and the second side of the cover plate body 21 can be the upper side and the lower side of the cover plate body 21 respectively.

[0067] The opposite sides of the opening 11 of the face frame 1 are respectively provided with the first elastic buckle 12 and the second elastic buckle 13, and the opposite first side and the second side of the cover plate body 21 are respectively provided with the buckle slot 22 and the buckle position part 23. Through the clamping cooperation of the first elastic buckle 12 and the buckle slot 22, and the clamping cooperation of the second elastic buckle 13 and the buckle position part 23, the limiting and fixing of the electric appliance cover plate 2 and the face frame 1 can be realized. The opposite first side and the second side of the cover plate body 21 are clamped and fixed, the fixing effect is good, and the electric appliance cover plate 2 can be effectively prevented from being lifted by the motor wire, and the tightening screw is convenient.

[0068] The first side and the second side of the cover plate body 21 can be the upper side and the lower side of the cover plate body 21 respectively, that is, the upper side and the lower side of the cover plate body 21 are clamped by the first elastic buckle 12 and the second elastic buckle 13. The first elastic buckle 12 or the second elastic buckle 13 located on the lower side can support the electric appliance cover plate 2, so as to prevent the electric appliance cover plate 2 from falling and being scratched under the action of gravity after the tightening screw is loosened.

[0069] In some example embodiments, as shown in Figure 7 , Figure 11 and Figure 16 , the second elastic buckle 13 comprises a second elastic arm 131 and a second buckle part 132, the second elastic arm 131 is connected with the face frame 1, and the second elastic arm 131 can be elastically deformed, and the second buckle part 132 is arranged on the second elastic arm 131 and protrudes towards the inner side of the opening 11.

[0070] As shown in Figure 7 , Figures 17-19 , the edge part of the cover plate body 21 close to the second side forms the buckle position part 23. Under the extrusion force between the buckle position part 23 and the second buckle part 132 of the second elastic buckle 13, the second elastic arm 131 is elastically deformed, so that the second buckle part 132 can pass over the buckle position part 23, and the clamping of the second elastic buckle 13 and the buckle position part 23 is realized.

[0071] Wherein, as shown in Figure 7 , Figure 11 and Figure 16As shown, the second clamping portion 132 is provided with a third guide slope 133 for guiding during the clamping cooperation between the second clamping portion 132 and the clamping portion 23. The third guide slope 133 can be a slanted plane or a curved surface, and can guide during the clamping process so as to clamp the second clamping portion 132 and the clamping portion 23, thereby facilitating the installation of the appliance cover plate 2.

[0072] It should be understood that the third guide slope can be provided only on the second clamping portion 132, or only on the clamping portion 23, or provided on both the clamping portion 23 and the second clamping portion 132.

[0073] By providing the first guide slope I 123, the first guide slope II 222 and the third guide slope 133, when the appliance cover plate 2 is installed, the clamping between the appliance cover plate 2 and the face frame 1 can be conveniently achieved by pressing the appliance cover plate 2.

[0074] In some example embodiments, as shown in Figure 7 , Figure 11 and Figure 16 As shown, the second clamping portion 132 is provided with a fourth guide slope 134 for guiding during the disengagement cooperation between the second clamping portion 132 and the clamping portion 23.

[0075] The fourth guide slope 134 can be a slanted plane or a curved surface, and can guide during the disengagement process so as to disengage the clamping between the second clamping portion 132 and the clamping portion 23, thereby facilitating the disassembly of the appliance cover plate 2 for maintenance, replacement or the like of the appliance elements.

[0076] It should be understood that the fourth guide slope can be provided only on the second clamping portion 132, or only on the clamping portion 23, or provided on both the clamping portion 23 and the second clamping portion 132.

[0077] In some example embodiments, as shown in Figure 7 , Figure 11 and Figure 16 The third guide slope 133 and the fourth guide slope 134 gradually approach along the protruding direction of the second clamping portion 132, so that the second clamping portion 132 can have a wedge shape.

[0078] In some example embodiments, as shown in Figures 17-19 The third side of the cover plate body 21 is provided with a handle portion 24, and the third side of the cover plate body 21 is adjacent to the first side and the second side. The handle portion 24 is arranged at the middle of the third side of the cover plate body 21, and the third side of the cover plate body 21 is the left side or the right side.

[0079] The cover plate body 21 is provided with a handle portion 24, so that when the appliance cover plate 2 is disassembled, the fastening screw is first loosened, and then the appliance cover plate 2 is flipped open by applying force to the handle portion 24, so as to realize the disengagement and disassembly of the appliance cover plate 2 from the face frame 1. Due to the arrangement of the second guide slope 223 and the fourth guide slope 134, the appliance cover plate 2 is relatively easy to flip and disassemble.

[0080] The handle portion 24 is arranged at the middle portion of the third side of the cover plate body 21, that is, the distance between the handle portion 24 and the first elastic buckle 12 and the second elastic buckle 13 of the face frame 1 is substantially equal, so that when the appliance cover plate 2 is flipped by applying force to the handle portion 24, the first elastic buckle 12 and the second elastic buckle 13 are balanced in force, and the first elastic buckle 12 and the second elastic buckle 13 are basically synchronized to disengage, so as to realize the disassembly of the appliance cover plate 2.

[0081] In some exemplary embodiments, as shown in Figure 1 The air conditioner indoor unit further includes a panel 3, a guide vane 4, a heat exchanger 5, and a bottom plate 6. The panel 3 can be fixed to the front portion of the face frame 1, the guide vane 4 can be arranged at the air outlet at the lower front portion of the face frame 1, the bottom plate 6 can be fixed to the bottom portion of the face frame 1, and the heat exchanger 5 can be arranged in the face frame 1.

[0082] The air conditioner indoor unit can be a wall-mounted air conditioner.

[0083] In summary, the scheme of the embodiments of the present application is to design two elastic buckles (the first elastic buckle and the second elastic buckle) on the face frame to engage the appliance cover plate, so that after the fastening screw is loosened, the appliance cover plate can be prevented from directly falling and being scratched during later maintenance. During production and assembly, the appliance cover plate is engaged by the two elastic buckles on the face frame, so that the motor wire cannot be lifted, the employee does not need to press the appliance cover plate with the left hand and tighten the fastening screw with the right hand, the screw tightening is convenient for the production line employees, and the production efficiency is greatly improved.

[0084] The first guide slope, the second guide slope, the third guide slope, and the fourth guide slope are arranged, so that the installation and disassembly of the appliance cover plate are convenient.
