Description

Housing and outdoor unit Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a housing and an outdoor unit. Background Art

[0002] In existing outdoor units, the top cover is connected to the front panel, back panel, and two side panels using screws. While this method secures the top cover to the panels, it requires a large number of screws, which not only increases the number of drilling steps during the manufacturing process but also requires multiple screw tightening operations during assembly and disassembly, resulting in low assembly and disassembly efficiency. Furthermore, the large number of screws can reduce the aesthetics of the outdoor unit.

[0003] Therefore, how to simplify the connection between the top cover and each plate and improve the efficiency of assembly and disassembly and the aesthetics is a technical problem that urgently needs to be solved.

[0004] Summary of the Invention

[0005] The problem solved by the present invention is that in the existing outdoor unit, the top cover and the panels are connected by a large number of screws, which not only causes trouble in manufacturing but also reduces the efficiency of assembly and disassembly.

[0006] To solve the above problems, in a first aspect, an embodiment of the present invention provides a housing for an outdoor unit, the housing comprising:

[0007] The top cover comprises a top plate and a front side plate, wherein the front side plate is connected to the edge of the top plate, and the edge of the front plate is provided with a front holding portion protruding inward;

[0008] The panel is connected to the inner side of the front side plate. A front groove is provided on the surface of the panel, and the front clamping part cooperates with the front groove.

[0009] The advantageous effects of the housing provided by the embodiment of the present invention include:

[0010] 1. The edge of the front plate of the top cover is provided with an inwardly protruding front retaining portion, and the surface of the panel is provided with a front groove. The front retaining portion cooperates with the front groove to realize the clamping connection between the top cover and the panel, eliminating the need for screw connection between the two and the need for pre-set screw holes. This not only simplifies the manufacturing process but also improves the efficiency of assembly and disassembly.

[0011] 2. The number of screws on the panel is reduced, which improves the aesthetics of the outdoor unit.

[0012] In an optional embodiment, the front holding portion is formed by bending the edge of the front side plate inward.

[0013] In this way, the front holding portion is formed simply and efficiently, and the connection strength with the front side plate is high.

[0014] In an optional embodiment, the length of the front holding portion is equal to the length of the front side plate.

[0015] In this way, the front clamping portion is extended to the entire length of the front plate, that is, the entire edge of the front plate is bent inward to form the front clamping portion, which is not only convenient to manufacture, but also can improve the clamping strength between the front plate and the panel.

[0016] In an optional embodiment, the top of the panel is punched inward to form a front recessed area, the front recessed area is punched outward to form a front convex portion, and a front groove is formed between the front convex portion and the lower side wall of the front recessed area.

[0017] In this way, not only is the front groove formed in a simple manner, but the front side plate is basically accommodated in the front recessed area, so that the front side plate does not protrude significantly relative to the panel, making the overall appearance of the shell relatively flat and beautiful.

[0018] In an optional embodiment, the length of the lower side wall of the front recessed area is equal to the length of the panel.

[0019] In this way, the front recessed area is equivalent to extending to the entire length of the panel, so that the front recessed area just accommodates the entire edge of the front side panel, so that the front side panel and the panel are assembled compactly.

[0020] In an optional embodiment, a plurality of front protrusions are spaced apart along the length direction of the lower side wall of the front recessed area.

[0021] In this way, the front convex parts arranged at intervals evenly squeeze the front holding part, so that the front holding part is evenly stressed, and the grooves have higher holding stability for the front holding part.

[0022] In an optional embodiment, the upper side wall of the front groove is inclined relative to the vertical direction, and the top end of the front clamping portion abuts against the upper side wall of the front groove.

[0023] In this way, the entire upper side wall of the front groove can be used to contact and cooperate with the front clamping part, avoiding insufficient manufacturing precision, difficulty in assembling the front groove and the front clamping part, or avoiding looseness of the front clamping part when assembled into the front groove.

[0024] In an optional embodiment, the top cover further comprises a rear side plate connected to the rear edge of the top plate, and an inwardly protruding rear retaining portion is provided on the edge of the rear side plate;

[0025] The shell also includes a back plate, which is connected to the inner side of the rear side plate. The surface of the back plate is provided with a rear groove, and the rear clamping part cooperates with the rear groove.

[0026] In this way, the edge of the rear plate of the top cover is provided with a rear clamping portion protruding inward, and the surface of the back plate is provided with a rear groove. The rear clamping portion cooperates with the rear groove to achieve a clamping connection between the top cover and the back plate. There is no need to set a screw connection between the two, and there is no need for preset screw holes. This not only simplifies the manufacturing process, but also improves the efficiency of disassembly and assembly; the number of screws on the rear panel is reduced, which improves the aesthetics of the outdoor unit.

[0027] In an optional embodiment, the top cover further includes two side panels, which are respectively connected to the left and right sides of the top panel;

[0028] The shell also includes two side panels, and the side panels are connected to the outer sides of the side panels and are connected by screws.

[0029] In this way, screws are arranged on the two side panels of the top cover to connect with the two side panels, thereby ensuring the connection strength between the top cover and the two side panels.

[0030] In a second aspect, an embodiment of the present invention provides an outdoor unit, the outdoor unit comprising:

[0031] The housing and panel are provided with ventilation holes;

[0032] The fan blade is installed in the housing and faces the vent;

[0033] The base is arranged at the bottom of the shell and is used to support the shell.

[0034] The number of screws on the housing of the outdoor unit provided by the embodiment of the present invention is reduced, which not only simplifies the manufacturing process but also improves the disassembly and assembly efficiency and the aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] It is worth noting that the front, back, left, right, up, and down mentioned in this embodiment are based on the outdoor unit's normal use state and are also commonly used terms by those skilled in the art, as shown by the directional arrows in FIG6 .

[0045] Referring to Figures 1, 4, and 6, this embodiment provides an outdoor unit 100, which includes a housing 4, fan blades 1, a condenser 2, and a base 3. The housing 4 includes a top cover 41, a panel 42, a back panel 43, and side panels 44. Of course, the outdoor unit 100 provided in this embodiment also includes other conventional components, which are not detailed here.

[0046] In this embodiment, the panel 42 and the back panel 43 are arranged opposite each other, one end of the panel 42 and the back panel 43 are connected to a side panel 44, and the other end of the panel 42 and the back panel 43 are connected to another side panel 44. The top cover 41 covers the top of the panel 42, the back panel 43, and the two side panels 44. The fan blade 1 is installed in the housing 4. The panel 42 is provided with a vent 424 (see Figure 6), and the fan blade 1 is directly opposite the vent 424. The condenser 2 is installed in the housing 4 and is arranged near the back panel 43. The base 3 is provided at the bottom of the housing 4 for supporting the housing 4.

[0047] Referring to Figures 2, 4, and 5, the top cover 41 includes a top plate 411 and a front panel 412. The front panel 412 is connected to the edge of the top plate 411. The edge of the front panel 412 is provided with a front retaining portion 413 that protrudes inward (pointing toward the interior of the housing 4). The panel 42 is connected to the inner side of the front panel 412. The surface of the panel 42 is provided with a front groove 421. The front retaining portion 413 cooperates with the front groove 421 to achieve a snap connection between the top cover 41 and the panel 42. There is no need to set a screw connection between the two, and there is no need for pre-set screw holes. This not only simplifies the manufacturing process but also improves the efficiency of disassembly and assembly. In addition, the number of screws on the front panel 42 is reduced, which improves the aesthetics of the outdoor unit 100.

[0048] The front holding portion 413 is formed by bending the edge of the front plate 412 inwardly. Like this, the front holding portion 413 is formed simply and efficiently, and the connection strength with the front plate 412 is high.

[0049] The length of the front retaining portion 413 is equal to the length of the front side panel 412, where the length refers to the length extending in the left-right direction. Thus, the front retaining portion 413 extends the entire length of the front side panel 412, i.e., the entire edge of the front side panel 412 is bent inward to form the front retaining portion 413. This not only facilitates manufacturing but also improves the strength of the connection between the front side panel 412 and the panel 42.

[0050] Referring to Figures 2, 4, and 5 to 7, the top of the panel 42 is punched inward to form a front recessed area 422, and a front convex portion 423 is punched outward (toward the exterior of the housing 4) from the interior of the front recessed area 422. A front groove 421 is formed between the front convex portion 423 and the lower sidewall of the front recessed area 422. This simplifies the formation of the front recessed area 421 and allows the front side panel 412 to be substantially contained within the front recessed area 422, preventing the front side panel 412 from protruding significantly relative to the panel 42, resulting in a relatively flat and aesthetically pleasing overall appearance of the housing 4.

[0051] The length of the lower sidewall of the front recessed area 422 is equal to the length of the panel 42, where the length refers to the length extending in the left-right direction. This means that the front recessed area 422 extends the entire length of the panel 42, just enough to accommodate the entire edge of the front side panel 412, allowing the front side panel 412 to fit tightly with the panel 42.

[0052] The plurality of front protrusions 423 are spaced apart along the length direction of the lower side wall of the front recessed area 422. In this way, the plurality of spaced front protrusions 423 uniformly squeeze the front clamping portion 413, so that the front clamping portion 413 is evenly stressed, and the grooves provide higher clamping stability for the front clamping portion 413.

[0053] 2 and 5 , the upper sidewall of the front groove 421 is tilted relative to the vertical direction, and the top of the front retaining portion 413 contacts the upper sidewall of the front groove 421. In this way, the entire upper sidewall of the front groove 421 can be used to contact and mate with the front retaining portion 413, avoiding insufficient manufacturing precision, difficulty in assembling the front groove 421 and the front retaining portion 413, or preventing the front retaining portion 413 from being loose after being assembled into the front groove 421.

[0054] Referring to Figures 1 and 3, the top cover 41 also includes a rear panel 414 connected to the rear edge of the top panel 411. The edge of the rear panel 414 is provided with a rear retaining portion 415 that protrudes inward (directing toward the interior of the housing 4). The back panel 43 is connected to the inner side of the rear panel 414. The surface of the back panel 43 is provided with a rear groove 431, and the rear retaining portion 415 engages with the rear groove 431. In this way, the edge of the rear panel 414 of the top cover 41 is provided with the rear retaining portion 415 that protrudes inward, and the surface of the back panel 43 is provided with the rear groove 431. The rear retaining portion 415 engages with the rear groove 431, so that the top cover 41 and the back panel 43 are connected by a clamping connection, eliminating the need for screws to connect the two, and thus eliminating the need for pre-set screw holes. This not only simplifies the manufacturing process but also improves the efficiency of assembly and disassembly. The number of screws on the rear panel 42 is reduced, thereby improving the aesthetics of the outdoor unit 100.

[0055] Specifically, the rear retaining portion 415 is formed by bending the edge of the rear side plate 414 inward (toward the interior of the housing 4). The top of the back plate 43 is also provided with a rear recessed area 432, which can also be stamped. A rear convex portion 433 is provided in the rear recessed area 432. The rear convex portion 433 is formed by stamping the material in the rear recessed area 432 outward (toward the exterior of the housing 4). A rear groove 431 is formed between the rear convex portion 433 and the lower side wall of the rear recess.

[0056] The top cover 41 in this embodiment (including the top plate 411, the front plate 412, the rear plate 414 and the two side plates) can be integrally formed or stamped from a single plate, so that the overall strength of the top cover 41 is greater and the connection strength between the plates is also greater.

[0057] The housing 4 further includes two side panels 44, which are connected to the outside of the side panels 44 and connected by screws. In this way, screws are set on the two side panels (not shown) of the top cover 41 to connect the two side panels 44, thereby ensuring the connection strength between the top cover 41 and the two side panels 44.

[0058] The housing 4 and the outdoor unit 100 provided by the embodiment of the present invention have the following beneficial effects:

[0059] 1. The edge of the front plate 412 of the top cover 41 is provided with an inwardly protruding front retaining portion 413, and the surface of the panel 42 is provided with a front groove 421. The front retaining portion 413 cooperates with the front groove 421 to achieve a snap connection between the top cover 41 and the panel 42, eliminating the need for screws or pre-set screw holes between the two. This not only simplifies the manufacturing process but also improves the efficiency of assembly and disassembly.

[0060] 2. The top of the front holding portion 413 contacts (maintains a mutual squeezing force) the inclined upper side wall of the front groove 421 to avoid insufficient manufacturing precision, difficulty in assembling the front groove 421 and the front holding portion 413, or looseness of the front holding portion 413 after being assembled into the front groove 421;

[0061] 3. The edge of the rear plate 414 of the top cover 41 is provided with an inwardly protruding rear retaining portion 415, and the surface of the back plate 43 is provided with a rear groove 431. The rear retaining portion 415 cooperates with the rear groove 431 to achieve a snap connection between the top cover 41 and the back plate 43, eliminating the need for screws connecting the two and thus eliminating the need for pre-set screw holes. This not only simplifies the manufacturing process but also improves the efficiency of assembly and disassembly.

[0062] 4. The number of screws on the panel 42 and the back panel 43 is reduced, thereby improving the aesthetics of the outdoor unit 100.

[0063] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
