Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and more specifically, to an air conditioner and a chassis cover. Background Technology

[0002] Existing air conditioner indoor units consist of a chassis and a chassis cover. The chassis cover is located at one end of the chassis. The chassis cover has a generally strip-shaped groove structure. One end of the chassis cover has a pipe outlet, and the other end is connected to the chassis. Because the end of the chassis cover with the pipe outlet is suspended and loose, it is prone to cracking in the event of an accidental drop, which is detrimental to the transportation and storage of the air conditioner. In particular, when the indoor unit needs to have refrigerant pipes installed from the side with the chassis cover, the side wall of the side with the pipe outlet needs to be removed to enlarge the pipe outlet into a larger opening. This further reduces the structural strength of the end of the chassis cover with the pipe outlet, further increasing the risk of damage to the chassis cover. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to prevent the chassis cover from cracking when it is accidentally dropped.

[0004] This utility model embodiment provides a chassis cover plate for an air conditioner, comprising:

[0005] The cover plate body includes a first end having an outlet hole and a second end opposite to the first end;

[0006] A first connecting portion, disposed at the first end, is used to connect to the chassis of the air conditioner; and...

[0007] The second connecting part is located at the second end and is used to connect to the chassis of the air conditioner.

[0008] In one illustrative embodiment, the first end is provided with a structural weakening zone located on one side of the outlet hole;

[0009] The first connecting portion is located on the side of the outlet hole facing away from the structural weakening area;

[0010] The structural strength of the weakened area is less than that of other parts of the cover plate body.

[0011] In one illustrative embodiment, the first connecting portion and the second connecting portion are configured as resilient snap-fits.

[0012] In one illustrative embodiment, a first positioning protrusion is further provided at the first end, the first positioning protrusion being configured to insert into a positioning groove on the chassis to achieve mutual positioning between the chassis cover and the chassis.

[0013] In one illustrative embodiment, the chassis cover is manufactured using an injection molding process, and both the first connecting portion and the first positioning protrusion are located at the parting surface of the mold.

[0014] In one illustrative embodiment, the first connecting portion includes:

[0015] An elastic support portion, one end of which is connected to the cover plate body, and located on one side of the first positioning protrusion and spaced apart from the first positioning protrusion; and,

[0016] The hook portion is disposed on the side of the elastic support portion opposite to the first positioning protrusion.

[0017] In one illustrative embodiment, the first positioning protrusion includes a plate body with one end connected to the cover plate body and a reinforcing rib plate connected to the cover plate body and the plate body.

[0018] This application also proposes an air conditioner, which includes a chassis cover and a chassis as described above, wherein a first mating part and a second mating part are provided on the chassis;

[0019] The first connecting part is connected to the first mating part, and the second connecting part is connected to the second mating part.

[0020] In one illustrative embodiment, the first mating portion and the second mating portion are configured as snap grooves.

[0021] In one illustrative embodiment, the chassis cover plate further includes a third connecting portion connected to the cover plate body, the third connecting portion being disposed between the first connecting portion and the second connecting portion;

[0022] The chassis is also provided with a third mating part that connects to the third connecting part.

[0023] This application also proposes an air conditioner, which includes a chassis cover and a chassis as described above, wherein a first mating part and a second mating part are provided on the chassis;

[0024] The first connecting part is connected to the first mating part, and the second connecting part is connected to the second mating part;

[0025] The chassis is also provided with a positioning groove adjacent to the first mating part, and the positioning groove accommodates the first positioning protrusion.

[0026] In the technical solution of this application, since the cover body of the chassis cover is provided with a first connecting part and a second connecting part at opposite ends, and both the first connecting part and the second connecting part are connected to the chassis, both ends of the chassis cover can be firmly fixed to the chassis. The chassis provides support to the opposite ends of the chassis cover, preventing the ends of the chassis cover from forming a cantilever beam, and avoiding the situation where the chassis cover cracks when the air conditioner falls.

[0027] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0040] like Figure 1 As shown, this embodiment proposes an air conditioner. The air conditioner includes an indoor unit 100. The indoor unit 100 includes a casing 3, a chassis 1, a fan, and a chassis cover 2. The casing 3 is provided with an air inlet 31, an air outlet 32, and an air duct. The air duct extends from the air inlet 31 to the air outlet 32. The chassis 1 is disposed inside the casing 3, and the fan is mounted on the chassis 1. The fan can be a cross-flow fan. The fan is located inside the air duct and is used to drive the air in the air duct to flow from the air inlet 31 to the air outlet 32, and to exit the casing 3 from the air outlet 32.

[0041] like Figures 2-6 As shown, a chassis cover 2 is disposed at one end of the chassis 1. The chassis cover 2 includes a cover body 21, a first connecting portion 213, and a second connecting portion 214. The cover body 21 can be constructed as a generally straight strip structure. The cover body 21 includes a first end 211 and a second end 212. The first end 211 and the second end 212 are disposed opposite to each other. A pipe outlet 2112 is provided on the first end 211. The pipe outlet 2112 is a through hole, which vertically penetrates the first end 211 of the chassis cover 2. The first connecting portion 213 is disposed at the first end 211 of the cover body 21, and the second connecting portion 214 is disposed at the second end 212 of the cover body 21. The first connecting portion 213 and the second connecting portion 214 can be disposed on the same side of the cover body 21.

[0042] like Figure 7 , 8As shown, the chassis 1 is provided with a first mating part 11 and a second mating part (not shown in the figure). The first mating part 11 and the second mating part are located at the same end of the chassis 1. The first mating part 11 and the second mating part are separate from each other. The first mating part 11 is connected to the first end 211 of the cover plate body 21, and the connection between the first mating part 11 and the first end 211 can be a snap-fit ​​connection, a screw connection, a riveting connection, or an adhesive connection. The second mating part is connected to the second end 212 of the cover plate body 21, and the connection between the second mating part and the second end 212 can be a snap-fit ​​connection, a screw connection, a riveting connection, or an adhesive connection.

[0043] Since the cover body 21 of the chassis cover plate 2 is provided with a first connecting part 213 and a second connecting part 214 at opposite ends, and both the first connecting part 213 and the second connecting part 214 are connected to the chassis 1, both ends of the chassis cover plate 2 can be firmly fixed to the chassis 1. The chassis 1 provides support for the opposite ends of the chassis cover plate 2, preventing the ends of the chassis cover plate 2 from forming a cantilever beam, and avoiding the situation where the chassis cover plate 2 cracks when the air conditioner falls.

[0044] In an illustrative embodiment, a structurally weakened region 2111 is provided at the first end 211 of the cover plate body 21. The structurally weakened region 2111 is located on one side of the outlet hole 2112. The structural strength of the structurally weakened region 2111 is less than the structural strength of other parts of the cover plate body 21. For example, a groove or a strip-shaped through hole is provided at the edge of the structurally weakened region 2111, and the groove or strip-shaped through hole extends along the edge of the structurally weakened region 2111. Also, for example, the thickness of the structurally weakened region 2111 is less than the thickness of other parts of the cover plate body 21. A first connecting portion 213 on the cover plate body 21 is located on the side of the cover plate body 21 with respect to the structurally weakened region 2111 at the outlet hole 2112.

[0045] When the air conditioner needs to extend the refrigerant pipe from one side of the chassis cover plate 2, the installer can cut off the structurally weakened area 2111 to enlarge the outlet hole 2112, facilitating the passage of the refrigerant pipe. At the same time, since the first connecting part 213 is located on the side of the outlet hole 2112 of the cover plate body 21 that faces away from the structurally weakened area 2111, and the first connecting part 213 is fixed to the chassis 1, even if the structurally weakened area 2111 is removed, the chassis 1 can still support the area around the outlet hole 2112 of the cover plate body 21, improving the structural strength of the cover plate body 21.

[0046] In an illustrative embodiment, the first connecting portion 213 is configured as a resilient snap-fit. The first mating portion 11 is configured as a snap-fit ​​groove, with the opening of the snap-fit ​​groove facing the chassis cover plate 2. The first connecting portion 213 can extend into the first mating portion 11 and hang on the first mating portion 11, forming a snap-fit ​​connection between the first connecting portion 213 and the first mating portion 11. The second connecting portion 214 is configured as a resilient snap-fit. The second mating portion is configured as a snap-fit ​​groove, with the opening of the snap-fit ​​groove facing the chassis cover plate 2. The second connecting portion 214 can extend into the second mating portion and hang on the second mating portion, forming a snap-fit ​​connection between the second connecting portion 214 and the second mating portion.

[0047] When assembling the chassis cover 2 onto the chassis 1, simply align the first connecting part 213 of the chassis cover 2 with the first mating part 11 of the chassis 1, align the second connecting part 214 of the chassis cover 2 with the second mating part of the chassis 1, and insert the first connecting part 213 and the second connecting part 214 into the first mating part 11 and the second mating part respectively to complete the assembly of the chassis cover 2 and the chassis 1.

[0048] In one illustrative embodiment, the chassis cover 2 further includes a first positioning protrusion 216. The first positioning protrusion 216 is configured to protrude. The first positioning protrusion 216 is disposed at a first end 211 of the chassis 1 body and protrudes beyond the first end 211 of the chassis 1 body.

[0049] A positioning groove 12 is provided on the end of the chassis 1. The opening of the positioning groove 12 faces the chassis cover plate 2. The shape of the positioning groove 12 matches the shape of the first positioning protrusion 216. The positioning groove 12 accommodates the first positioning protrusion 216.

[0050] After the first positioning protrusion 216 on the chassis cover plate 2 is inserted into the positioning groove 12 of the chassis 1, the first end 211 of the chassis cover plate 2 is positioned with the chassis 1, which further enhances the connection between the first end 211 of the chassis cover plate 2 and the chassis 1, and increases the support of the chassis 1 for the first end 211, making the chassis cover plate 2 less likely to crack when it falls.

[0051] In one illustrative embodiment, the chassis cover 2 is a plastic product, which may be manufactured using an injection molding process. The first connecting portion 213 and the first positioning protrusion 216 are both located at the parting surface.

[0052] During injection molding, molten plastic is injected into the mold for shaping the chassis cover plate 2. During mold opening, the mold is separated from its parting surface to facilitate the removal of the molded chassis cover plate 2. Both the first connecting part 213 and the first positioning protrusion 216 are located at the parting surface of the mold, allowing for direct ejection from the moving and fixed molds. This simple structure eliminates the need for additional mold structures to form the first connecting part 213 and the first positioning protrusion 216.

[0053] In an illustrative embodiment, the first connecting portion 213 includes an elastic support portion 2131 and a hook portion 2132. The first connecting portion 213 may be made of plastic. The elastic support portion 2131 may be configured as a generally plate-like structure or a rod-like structure. One end of the elastic support portion 2131 is connected to the first end 211 of the cover plate body 21. The elastic support portion 2131 is elastic and can undergo elastic deformation by bending. The elastic support portion 2131 is located on one side of the first positioning protrusion 216 and is spaced apart from the first positioning protrusion 216. The elastic support portion 2131 may be provided on the side of the first positioning protrusion 216 facing away from the second end 212. The hook portion 2132 is provided on the side of the elastic support portion 2131 facing away from the first positioning protrusion 216. The hook portion 2132 hooks onto the protrusion on the inner sidewall of the first mating portion 11.

[0054] Thus, during the insertion of the first connecting part 213 into the first mating part 11, the hook 2132 of the first connecting part 213 is squeezed by the protrusion of the first mating part 11, causing the elastic support part 2131 to bend and deform elastically. After the first connecting part 213 is fully inserted into the first mating part 11, the hook 2132 hooks onto the protrusion of the first mating part 11 under the elastic force of the elastic support part 2131, thereby achieving a snap-fit ​​connection between the first connecting part 213 and the first mating part 11. The first positioning protrusion 216 is located on the side of the elastic support part 2131 facing away from the hook 2132 and is inserted into the positioning groove 12, ensuring that the first end 211 will not move relative to the chassis 1, thus preventing the hook 2132 of the first connecting part 213 from coming out of the first mating part 11.

[0055] In one illustrative embodiment, the first positioning protrusion 216 includes a plate 2161 and a reinforcing rib 2162. The plate 2161 may be configured as a flat plate. One end of the plate 2161 is connected to the first end 211 of the cover plate body 21. The plate 2161 may extend parallel to the extension direction of the cover plate body 21. The reinforcing rib 2162 is configured as a triangular plate, with one half of the reinforcing rib 2162 connected to the first end 211 of the cover plate body 21, and the other side of the reinforcing rib 2162 connected to the surface of the plate 2161.

[0056] The reinforcing rib 2162 can enhance the structural strength of the plate 2161, making the overall structural strength of the first positioning protrusion 216 higher and less prone to bending.

[0057] In one illustrative embodiment, the end of the plate 2161 facing away from the cover plate body 21 gradually narrows in width in the direction away from the cover plate body 21. The end of the plate 2161 facing away from the cover plate body 21 can be configured as a pointed end, for example, it can be configured as an obtuse angle or an acute angle.

[0058] In this way, the plate 2161 can be inserted into the positioning groove 12 more smoothly, and the assembly between the chassis cover plate 2 and the chassis 1 is simpler.

[0059] In one illustrative embodiment, the chassis cover 2 further includes a third connecting portion 215. The third connecting portion 215 is disposed in the central region of the cover body 21, that is, the third connecting portion 215 is located between the first connecting portion 213 and the second connecting portion 214. The third connecting portion 215 may be configured as a snap-fit. The third connecting portion 215 and the first connecting portion 213 are located on the same side of the cover body 21.

[0060] The chassis 1 is also provided with a third mating part. The third mating part can be constructed as a snap-fit ​​groove. The third connecting part 215 is connected to the third mating part. The connection between the third mating part and the third connecting part 215 can be a screw connection, a snap-fit ​​connection, a riveting, or an adhesive connection.

[0061] Since the second connecting part 214 of the chassis cover 2 is connected to the chassis 1, the middle part of the chassis cover 2 is firmly fixed to the chassis 1, and the chassis 1 provides support for the middle part of the chassis cover 2, which can further prevent the chassis cover 2 from cracking when the air conditioner falls.

[0062] In one illustrative embodiment, the chassis cover 2 further includes a second positioning protrusion 217. The second positioning protrusion 217 is configured to protrude. The second positioning protrusion 217 is disposed at the second end 212 of the chassis 1 body and protrudes beyond the second end 212 of the chassis 1 body.

[0063] A first positioning hole (not shown in the figure) is provided on the end of the chassis 1. One end of the first positioning hole faces the chassis cover plate 2. The first positioning hole can accommodate the second positioning protrusion 217.

[0064] After the second positioning protrusion 217 on the chassis cover plate 2 is inserted into the first positioning hole of the chassis 1, the first positioning hole and the second positioning protrusion 217 are fitted together with a clearance, thereby realizing the mutual positioning of the second end 212 of the chassis cover plate 2 and the chassis 1, further enhancing the connection between the second end 212 of the chassis cover plate 2 and the chassis 1, increasing the support of the chassis 1 for the second end 212, and making the chassis cover plate 2 less prone to cracking when falling.

[0065] In one illustrative embodiment, the chassis cover 2 further includes a third positioning protrusion 218. The third positioning protrusion 218 is constructed in a protruding shape. The third positioning protrusion 218 is located in the central region of the chassis 1 body, and the third positioning protrusion 218 may be close to the third connecting portion 215, and the third positioning protrusion 218 also protrudes from the chassis 1 body. The first positioning protrusion 216, the second positioning protrusion 217 and the third positioning protrusion 218 are all located on the side of the chassis 1 body where the first connecting portion 213 is located.

[0066] A second positioning hole (not shown in the figure) is provided on the end of the chassis 1. One end of the second positioning hole faces the chassis cover plate 2. The second positioning hole can accommodate the third positioning protrusion 218.

[0067] After the third positioning protrusion 218 on the chassis cover plate 2 is inserted into the second positioning hole of the chassis 1, the second positioning hole and the third positioning protrusion 218 are fitted together with a clearance, thereby realizing the mutual positioning of the middle part of the chassis cover plate 2 and the chassis 1, further enhancing the connection between the middle part of the chassis cover plate 2 and the chassis 1, improving the support of the chassis 1 for the middle part of the end cover, and making the chassis cover plate 2 less likely to crack when it falls.
