Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a housing and an outdoor unit. Background Technology

[0002] In existing outdoor units, the top cover is connected to the front panel, back panel, and two side panels with screws. While this securely connects the top cover to the panels, it results in a large number of screws. This not only requires more drilling during manufacturing but also necessitates multiple screw-tightening operations during assembly and disassembly, leading to low efficiency. Furthermore, the large number of screws also detracts from the aesthetics of the outdoor unit.

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

[0004] The problem solved by this invention is that in existing outdoor units, there are many screws connecting the top cover and each plate, which not only makes manufacturing troublesome but also results in low disassembly and assembly efficiency.

[0005] To address the aforementioned problems, in a first aspect, embodiments of the present invention provide a housing for use in an outdoor unit, the housing comprising:

[0006] The top cover includes a top plate and a front plate, the front plate being connected to the edge of the top plate, and the edge of the front plate being provided with an inwardly protruding front retaining part;

[0007] The panel is connected to the inside of the front panel. The surface of the panel is provided with a front groove, and the front retaining part cooperates with the front groove.

[0008] The beneficial effects of the housing provided in the embodiments of the present invention include:

[0009] 1. The front edge of the top cover has an inwardly protruding front retaining part, and the surface of the panel has a front groove. The front retaining part and the front groove cooperate to achieve a snap-fit ​​between the top cover and the panel, eliminating the need for screws between them and thus eliminating the need for pre-drilled screw holes. This not only simplifies the manufacturing process but also improves the efficiency of disassembly and assembly.

[0010] 2. The number of screws on the panel has been reduced, improving the aesthetics of the outdoor unit.

[0011] In an optional embodiment, the front retaining portion is formed by bending inward from the edge of the front side plate.

[0012] In this way, the front retaining part is simple and efficient to form, and has a high connection strength with the front side plate.

[0013] In an optional embodiment, the length of the front retaining portion is equal to the length of the front side plate.

[0014] In this way, the front retaining part extends to the entire length of the front panel, that is, the entire edge of the front panel is bent inward to form the front retaining part, which not only makes manufacturing easier, but also improves the snap-fit ​​strength between the front panel and the panel.

[0015] In an optional embodiment, the top of the panel is punched inward to form a front recessed area, and a front protrusion is punched outward within the front recessed area to form a front protrusion. A front groove is formed between the front protrusion and the lower sidewall of the front recessed area.

[0016] In this way, not only is the formation of the front groove simple, but the front panel is also basically accommodated in the front recessed area, so that the front panel does not protrude significantly relative to the panel, making the overall shape of the shell relatively flat and beautiful.

[0017] In an optional implementation, the length of the lower sidewall of the front recess is equal to the length of the panel.

[0018] In this way, the front recess extends to the entire length of the panel, just enough to accommodate the entire edge of the front panel, making the front panel fit tightly with the panel.

[0019] In an optional embodiment, a plurality of protruding portions are spaced apart along the length direction of the lower sidewall of the front recessed area.

[0020] In this way, the multiple spaced protrusions evenly compress the front retaining part, making the front retaining part subject to uniform force and the grooves provide greater retaining stability to the front retaining part.

[0021] In an optional embodiment, the upper sidewall of the front groove is inclined relative to the vertical direction, and the top of the front retaining part abuts against the upper sidewall of the front groove.

[0022] In this way, the entire upper sidewall of the front groove can be used to contact and engage with the front retaining part, avoiding insufficient manufacturing precision, difficulty in assembling the front groove and the front retaining part, or looseness after the front retaining part is assembled into the front groove.

[0023] In an optional embodiment, the top cover also includes a rear side plate, which is connected to the rear edge of the top plate, and the edge of the rear side plate is provided with an inwardly protruding rear retaining portion.

[0024] The housing also includes a back plate, which is connected to the inside of the rear side plate. The surface of the back plate is provided with a rear groove, and the rear retaining part cooperates with the rear groove.

[0025] In this way, the rear edge of the top cover has an inwardly protruding rear retaining part, and the surface of the back panel has a rear groove. The rear retaining part and the rear groove cooperate to achieve a snap-fit ​​connection between the top cover and the back panel, eliminating the need for screw connections between the two and thus eliminating the need for pre-drilled 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, improving the aesthetics of the outdoor unit.

[0026] In an optional embodiment, the top cover also includes two side panels, which are respectively connected to the left and right sides of the top plate;

[0027] The housing also includes two side plates, which are attached to the outside of the side plates and connected by screws.

[0028] In this way, screws are installed on the two side plates of the top cover to connect with the two side plates, ensuring the connection strength between the top cover and the two side plates.

[0029] Secondly, embodiments of the present invention provide an outdoor unit, the outdoor unit comprising:

[0030] The aforementioned housing has ventilation openings on its panel;

[0031] The fan blades are installed inside the housing and face the ventilation opening.

[0032] The base, located at the bottom of the housing, is used to support the housing.

[0033] The outdoor unit casing provided by this invention has a reduced number of screws, which not only simplifies the manufacturing process but also improves disassembly and assembly efficiency and aesthetics. Attached Figure Description

Detailed Implementation

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] It is worth noting that the terms "front," "back," "left," "right," "up," and "down" used in this embodiment refer to the outdoor unit under normal operating conditions and are also the terms commonly used by those skilled in the art. Figure 6 As indicated by the arrow in the center.

[0044] Please refer to Figure 1 , Figure 4 and Figure 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 front panel 42, a back panel 43, and a side panel 44. Of course, the outdoor unit 100 provided in this embodiment also includes other conventional components, which will not be described in detail here.

[0045] In this embodiment, the front panel 42 and the back panel 43 are arranged opposite to each other. One end of the front panel 42 and the back panel 43 is connected to a side panel 44, and the other end of the front panel 42 and the back panel 43 is connected to another side panel 44. The top cover 41 covers the top of the front panel 42, the back panel 43, and the two side panels 44. The fan blade 1 is installed inside the housing 4. The front panel 42 has a ventilation opening 424 (see [reference]). Figure 6 The fan blade 1 faces the vent 424. The condenser 2 is installed inside the housing 4 and is located near the back plate 43. The base 3 is located at the bottom of the housing 4 and is used to support the housing 4.

[0046] Please refer to Figure 2 , Figure 4 and Figure 5The 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, and the edge of the front panel 412 is provided with an inwardly protruding front retaining part 413 (pointing towards the inside of the housing 4). The front panel 42 is connected to the inner side of the front panel 412, and the surface of the front panel 42 is provided with a front groove 421. The front retaining part 413 cooperates with the front groove 421, so that the top cover 41 and the front panel 42 are snapped together, eliminating the need for screws between them and thus eliminating the need for pre-drilled screw holes. This not only simplifies the manufacturing process but also improves the efficiency of assembly and disassembly. In addition, the number of screws on the front panel 42 is reduced, improving the aesthetics of the outdoor unit 100.

[0047] The front retaining part 413 is formed by bending inward from the edge of the front side plate 412. In this way, the front retaining part 413 is simple and efficient to form, and has a high connection strength with the front side plate 412.

[0048] 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. In this way, the front retaining portion 413 extends to the entire length of the front side panel 412, that is, the entire edge of the front side panel 412 is bent inward to form the front retaining portion 413, which not only facilitates manufacturing, but also improves the snap-fit ​​strength between the front side panel 412 and the panel 42.

[0049] Please refer to Figure 2 , Figure 4 and Figures 5-7 The top of panel 42 is punched inward to form a front recessed area 422, and the front recessed area 422 is punched outward (towards the outside of housing 4) to form a front protrusion 423. A front groove 421 is formed between the front protrusion 423 and the lower sidewall of the front recessed area 422. In this way, not only is the formation of the front groove 421 simple, but the front side plate 412 is basically accommodated in the front recessed area 422, so that the front side plate 412 does not protrude significantly relative to panel 42, making the overall shape of housing 4 relatively flat and beautiful.

[0050] 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. In this way, the front recessed area 422 extends to the entire length of the panel 42, just enough to accommodate the entire edge of the front side panel 412, so that the front side panel 412 and the panel 42 are fitted tightly together.

[0051] Multiple protruding portions 423 are spaced apart along the length of the lower sidewall of the front recessed area 422. In this way, the multiple spaced protruding portions 423 uniformly compress the front retaining portion 413, making the front retaining portion 413 subject to uniform force and improving the retaining stability of the groove on the front retaining portion 413.

[0052] Please refer to Figure 2 and Figure 5 The upper sidewall of the front groove 421 is inclined relative to the vertical direction, and the top end of the front retaining part 413 abuts against 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 cooperate with the front retaining part 413, avoiding insufficient manufacturing precision, difficulty in assembling the front groove 421 and the front retaining part 413, or looseness of the front retaining part 413 after assembly into the front groove 421.

[0053] Please refer to Figure 1 and Figure 3 The top cover 41 also includes a rear side plate 414, which is connected to the rear edge of the top plate 411. The edge of the rear side plate 414 is provided with an inwardly protruding rear retaining part 415 (pointing towards the inside of the housing 4). The back plate 43 is connected to the inner side of the rear side plate 414, and the surface of the back plate 43 is provided with a rear groove 431, which engages with the rear retaining part 415. In this way, the rear side plate 414 of the top cover 41 has an inwardly protruding rear retaining part 415, and the surface of the back plate 43 has a rear groove 431. The engagement of the rear retaining part 415 with the rear groove 431 enables the top cover 41 and the back plate 43 to be snapped together, eliminating the need for screws between them and pre-drilled screw holes. This simplifies the manufacturing process and improves the efficiency of disassembly and assembly. The number of screws on the rear panel 42 is reduced, improving the aesthetics of the outdoor unit 100.

[0054] Specifically, the rear retaining part 415 is formed by bending inward from the edge of the rear side plate 414 (pointing towards the inside 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 protrusion 433 is provided in the rear recessed area 432. The rear protrusion 433 is formed by stamping outward from the material in the rear recessed area 432 (pointing towards the outside of the housing 4). A rear groove 431 is formed between the rear protrusion 433 and the lower side wall of the rear recess.

[0055] In this embodiment, the top cover 41 (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 sheet of material, which makes the overall strength of the top cover 41 greater and the connection strength between the plates also greater.

[0056] The housing 4 also includes two side plates 44, which are connected to the outside of the side plates 44 by screws. In this way, screws are provided on the two side plates (not shown in the figure) of the top cover 41 to connect with the two side plates 44, ensuring the connection strength between the top cover 41 and the two side plates 44.

[0057] The beneficial effects of the housing 4 and outdoor unit 100 provided in this embodiment of the invention include:

[0058] 1. The edge of the front panel 412 of the top cover 41 is provided with an inwardly protruding front retaining part 413, and the surface of the panel 42 is provided with a front groove 421. The front retaining part 413 and the front groove 421 cooperate to achieve a snap-fit ​​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 to pre-set screw holes. This not only simplifies the manufacturing process, but also improves the efficiency of disassembly and assembly.

[0059] 2. The top end of the front retaining part 413 abuts (maintains a mutual squeezing force) on 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 retaining part 413, or to avoid the front retaining part 413 being loose after being assembled into the front groove 421.

[0060] 3. The rear plate 414 of the top cover 41 is provided with an inwardly protruding rear retaining part 415, and the surface of the back plate 43 is provided with a rear groove 431. The rear retaining part 415 and the rear groove 431 cooperate to achieve a snap-fit ​​between the top cover 41 and the back plate 43. There is no need to set a screw connection between the two, and there is no need to pre-set screw holes. This not only simplifies the manufacturing process, but also improves the efficiency of disassembly and assembly.

[0061] 4. The number of screws on the front panel 42 and back panel 43 has been reduced, improving the aesthetics of the outdoor unit 100.

[0062] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
