Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning equipment technology, and in particular to a panel and an air conditioner. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Currently, the method of fixing fiberglass wool in air conditioners is mostly to weld, bend, and fold the edges for fixation. This involves many steps and requires additional parts. It also places certain demands on the time required and the positioning and welding. Welding, bending, and folding can also lead to poor coating and potential failures. Furthermore, inaccurate positioning can cause the fiberglass wool to warp, which can lead to air leakage between the fiberglass wool and sheet metal. In some applications, this can result in serious condensation problems. Utility Model Content

[0004] The purpose of this invention is to at least solve the problem that existing methods for fixing insulation boards in air conditioners involve numerous steps and require additional components, leading to long production times. This objective is achieved through the following technical solution: The first aspect of this utility model provides a plate for a housing assembly of an air conditioner. The plate has an opening, and a portion of the plate located around the opening has a plurality of bending and fixing structures. The plurality of bending and fixing structures are spaced apart circumferentially along the opening and are integral with the housing assembly. An installation space for fixing an insulation board is formed between the portion of the bending and fixing structure and the plate.

[0005] The plate body proposed in the first aspect of this utility model can be used as part of the shell assembly of an air conditioner. The plate body has an opening, which can serve as an inlet or outlet for the shell assembly. The portion of the plate body located around the opening is integrally bent and flanged to form a bent fixing structure, which can fix the insulation board attached to the plate body. This eliminates the need for additional welding or installation of the insulation board, reducing the number of workpieces. Furthermore, by bending the periphery of the opening during the processing of the plate body, an unbent bent fixing structure can be formed. When it is necessary to fix the insulation board, the bent fixing structure can be further bent, making processing convenient and the integrated structure highly reliable.

The portion of the plate located around the opening is integrally bent and flanged to form a bending and fixing structure, which can fix an insulation board attached to the plate. This eliminates the need for additional welding or installation of the insulation board, reducing the number of workpieces. Furthermore, the bending and fixing structure can be formed by bending the periphery of the opening during the processing of the plate.

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0020] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0021] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0022] like Figures 1 to 5 As shown, the first aspect of this utility model proposes a plate (41) for a housing assembly (10) of an air conditioner (100). The plate (41) has an opening (42). A plurality of bending and fixing structures (43) are formed on the periphery of the opening (42) of the plate (41). The plurality of bending and fixing structures (43) are spaced apart along the circumferential direction of the opening (42) and are integral with the housing assembly (10). An installation space (435) for fixing a heat insulation board (44) is formed between the part of the bending and fixing structure (43) and the plate (41).

[0023] As can be seen, the plate (41) proposed in the first aspect of this utility model can be used as part of the shell assembly (10) of the air conditioner (100). The plate (41) is provided with an opening (42), which can be used as the inlet or outlet of the shell assembly (10) of the air conditioner (100). The part of the plate (41) located on the periphery of the opening (42) is formed by integral bending and flanging to form a bending and fixing structure (43), which can fix the insulation board (44) attached to the plate (41). There is no need for additional welding or installation of the insulation board (44), which reduces the number of workpieces. Moreover, when processing the opening (42), the plate can be bent to form an unbent bending and fixing structure (43) by bending the periphery of the opening (42). When it is necessary to fix the insulation board (44), the bending and fixing structure (43) can be bent again, which is convenient to process and the integral structure has strong reliability.

[0024] For example, the plate (41) can be a metal plate, with a rectangular opening (42) formed by a punching process. The opening (42) can serve as the outer shell of the air conditioner (100), that is, the air inlet or air outlet (101) on the shell assembly (10) of the air conditioner (100). To ensure the normal operation of the air conditioner (100), it is necessary to insulate the inside of the air conditioner (100). An insulation board (44) can be attached to the inside of the shell assembly (10) to achieve insulation. The shell assembly (10) can be composed of multiple plates welded, snapped together, or connected by fasteners. When the plate (41) is punched open (42), the outline of the punch is reserved for a flat bending and fixing structure (43). After punching, a bending and fixing structure (43) is formed integrally connected with the plate (41). The bending and fixing structure (43) is then bent multiple times so that the bending and fixing structure (43) has a part opposite to the plate (41). An installation space (435) is formed between the bending and fixing structure (43) and the plate (41) to limit or clamp the insulation board (44). After the edge of the insulation board (44) is inserted into the installation space (435), the bending and fixing structure (43) can be pressed to fix the insulation board (44).

[0025] In some embodiments of this utility model, the bending fixing structure (43) includes a first bending part (431) and a second bending part (432). Along the axial direction of the opening (42), the first bending part (431) is disposed opposite to the plate (41) and forms an installation space (435). The two ends of the second bending part (432) along the axial direction of the opening (42) are integrally connected to the first bending part (431) and the plate (41) respectively.

[0026] Among them, the axial direction of the opening (42) refers to the direction of extension of the central axis of the opening (i.e., the direction of airflow through the opening); the circumferential direction of the opening (42) refers to the circumferential direction around the central axis of the opening (i.e., the circumferential direction along the edge of the opening).

[0027] As can be seen, the bending and fixing structure (43) is a two-bending structure. The first bending part (431) is set opposite to the plate (41) and forms an installation space (435) to limit or clamp the edge of the insulation board (44), so that the bending and fixing structure (43) is easy to process and easy to assemble with the insulation board (44).

[0028] For example, when the plate (41) is punched open (42), the outline of the punch is reserved for a bending and fixing structure (43) in a flat state. The first bending part (431) and the second bending part (432) are coplanar at this time. The bending and fixing structure (43) can be rectangular or trapezoidal at this time. After punching, the first bending part (431) and the second bending part (432) are integrally connected with the plate (41). By bending the second bending part (432) and the first bending part (431) in sequence, an installation space (435) is formed.

[0029] In some embodiments of this utility model, a first pre-bending line is formed at the connection between the first bending portion (431) and the second bending portion (432), and a first stress relief portion (433) is provided at the first pre-bending line, the first stress relief portion (433) extending along the first pre-bending line.

[0030] It can be seen that by setting the first stress relief part (433), it is convenient to manually bend the fixed structure (43) and improve production efficiency.

[0031] For example, the first stress relief part (433) may be a strip groove, a strip hole, or a plurality of small holes spaced apart along the first pre-bending line, so that the structural strength at this point is relatively weak and easy to bend manually.

[0032] In some embodiments of this utility model, a second pre-bending line is formed at the connection between the second bending portion (432) and the plate (41), and a second stress relief portion (434) is provided at the second pre-bending line, the second stress relief portion (434) extending along the second pre-bending line.

[0033] It can be seen that by setting the second stress relief part (434), it is convenient to manually bend the fixed structure (43) and improve production efficiency.

[0034] For example, the second stress relief part (434) may be a strip groove, a strip hole, or a plurality of small holes spaced apart along the second pre-bending line, so that the structural strength at this point is relatively weak and easy to bend manually.

[0035] In some embodiments of the present invention, the first stress relief part (433) includes a plurality of first strip holes spaced apart along the first pre-bending line, the first strip holes extending along the first pre-bending line.

[0036] It can be seen that by setting the first strip hole, the structural strength of the bending fixing structure (43) at the first pre-bending line is weakened, making it easy to be bent manually.

[0037] For example, the first strip hole can be achieved by punching a hole at the first pre-bending line after reserving a flat plate state bending fixing structure (43) in the outline of the punch.

[0038] In some embodiments of the present invention, the second stress relief part (434) includes a plurality of second strip holes spaced apart along the second pre-bending line, the second strip holes extending along the second pre-bending line.

[0039] It can be seen that by setting the second strip hole, the structural strength of the bending fixing structure (43) at the second pre-bending line is weakened, making it easy to be bent manually.

[0040] For example, the second strip hole can be achieved by punching the first pre-bending line after reserving a flat plate state bending fixing structure (43) in the outline of the punch.

[0041] The second aspect of this utility model provides an air conditioner (100), comprising: The housing assembly (10) includes the plate (41) proposed in the first aspect of this utility model.

[0042] Insulation board (44), the edge of the insulation board (44) is embedded in the installation space (435).

[0043] The second aspect of this utility model proposes an air conditioner (100) with a shell assembly (10) that is easy to process and has high reliability. The plate (41) can be part of the shell assembly (10) of the air conditioner (100) and has an opening (42). The opening (42) can be used as the inlet or outlet of the shell assembly (10) of the air conditioner (100). The part of the plate (41) located on the periphery of the opening (42) is formed by integrally bending and flanging to form a bending and fixing structure (43), which can fix the insulation board (44) attached to the plate (41). There is no need for additional welding or installation of the insulation board (44), which reduces the number of workpieces. Moreover, when processing the opening (42), the plate can be bent to form an unbent bending and fixing structure (43) by bending the periphery of the opening (42). When it is necessary to fix the insulation board (44), the bending and fixing structure (43) can be bent again, which is convenient to process and has high reliability of integral structure.

[0044] For example, a rectangular opening (42) is formed by a punching process. The opening (42) can serve as the outer shell of the air conditioner (100), that is, the air inlet or air outlet (101) on the shell assembly (10) of the air conditioner (100). To ensure the normal operation of the air conditioner (100), it is necessary to insulate the inside of the air conditioner (100). An insulation board (44) can be attached to the inside of the shell assembly (10) to achieve insulation. The shell assembly (10) can be composed of multiple plates welded, snapped together or connected by fasteners. When the plate (41) is punched open (42), the outline of the punch is reserved for a flat bending and fixing structure (43). After punching, a bending and fixing structure (43) is formed integrally connected with the plate (41). The bending and fixing structure (43) is then bent multiple times so that the bending and fixing structure (43) has a part opposite to the plate (41). An installation space (435) is formed between the bending and fixing structure (43) and the plate (41) to limit or clamp the insulation board (44). After the edge of the insulation board (44) is inserted into the installation space (435), the bending and fixing structure (43) can be pressed to fix the insulation board (44).

[0045] In some embodiments of this utility model, the insulation board (44) has a clearance opening (441), which is connected to the opening (42), and the portion of the insulation board (44) located on the periphery of the clearance opening (441) is embedded in the installation space (435).

[0046] It can be seen that by setting an avoidance opening (441) on the insulation board (44), the opening (42) is not blocked by the insulation board (44), which improves the gas flow efficiency of the air conditioner (100).

[0047] For example, the clearance opening (441) of the insulation board (44) can be the same rectangle as the opening (42), and the cross section of the clearance opening (441) is larger than that of the opening (42), so that the insulation board (44) does not block the opening (42). The insulation board (44) around the clearance opening (441) can be snapped into the installation space (435), and then the first bending part (431) is bent towards the board body (41) to clamp the insulation board (44).

[0048] In addition, the insulation board (44) can be a single board with at least one clearance opening (441), or multiple boards can be enclosed to form at least one clearance opening (441).

[0049] In some embodiments of this utility model, the air conditioner (100) further includes a gas system (20), the gas system (20) includes a gas heat exchange tube (21), and the number of openings (42) is two. A heating air duct is formed in the housing assembly (10) through one of the openings (42), the gas heat exchange tube (21) and the other opening (42) in sequence. The airflow entering the heating air duct exchanges heat with the burning gas through the gas heat exchange tube (21).

[0050] As can be seen, when the air conditioner (100) is an air conditioner (100) with a gas system (20) (e.g., a gas rooftop unit), the panel is located on the indoor side of the air conditioner (100) and needs to be insulated to prevent condensation from forming on the housing assembly (10). The panel can be used to facilitate the installation of the insulation board (44) and improve the reliability and durability of the housing assembly (10). At this time, the opening (42) on the panel can serve as the air inlet and outlet (101) of the gas rooftop unit, and the insulation board (44) is arranged around the air inlet and outlet (101).

[0051] For example, an air conditioner (100) with a gas system (20) has a refrigeration system (30) consisting of a compressor, a heat exchanger, a fan and a piping system, and also has a gas system (20) that heats air by gas heat exchange. The gas system (20) burns gas through a burner assembly. The burned gas enters the gas heat exchanger and is then discharged from the exhaust fan. At the same time, external air enters the housing assembly (10) from the air inlet under the drive of the fan and is heated at the gas heat exchanger. The heated gas flows out from the air outlet (101), thus achieving efficient heating of air by the gas system (20).

[0052] In some embodiments of this utility model, the insulation board (44) is a fiberglass wool board.

[0053] It can be seen that by laying fiberglass wool board on the inside of the housing assembly (10) to insulate the air conditioner (100), the working environment of the air conditioner (100) meets the requirements.

[0054] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
