Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit technology, and in particular to an anti-scratch shell for an air conditioner outdoor unit and an air conditioner outdoor unit including the anti-scratch shell. Background Technology

[0002] For ease of maintenance, existing air conditioner outdoor units are generally equipped with a removable maintenance panel. When internal parts of the air conditioner outdoor unit need to be repaired, the maintenance panel can be removed for repair, and then reinstalled after the repair is completed.

[0003] like Figure 1 As shown, based on the existing structure of the outdoor unit casing 100, the position of the maintenance panel 160 is significantly restricted during reinstallation due to the presence of a top cover 130 at the top, a right rear panel 110 at the right rear, a front panel 120 on the left, and a corner frame 150 at the bottom. To successfully install the maintenance panel 160, it must be inserted diagonally from bottom to top into the installation position, ensuring the mounting portion 161 of the maintenance panel 160 is inside the top cover 130, and then the screws are tightened to complete the reinstallation of the maintenance panel.

[0004] During installation, the maintenance plate 160 needs to be pushed back first and then pulled up. During this process, the inner flange of the maintenance plate 160 is very close to the outer surface of the corner frame 150, so it is inevitable that they will come into contact with the outer end face of the corner frame 150. Since the corner frame 150 is an exterior component, scratches and damage are not permitted to avoid affecting the overall aesthetics of the outdoor unit.

[0005] Therefore, to prevent scratches on the corner frame during assembly, existing techniques typically involve attaching adhesive tape to the back of the repair panel 160 to prevent direct contact between the sheet metal parts and the scratches. However, this solution increases costs, hinders the simplification of the maintenance process, and offers poor scratch protection that is difficult to maintain long-term, exhibiting significant limitations and shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide an anti-scratch outer casing and outdoor unit for air conditioners, addressing the problem of easily scratching or damaging the corner frame during the reinstallation of the maintenance panel due to installation limitations. By providing an inwardly bent connecting portion at the upper part of the corner frame and a second part of the corner frame extending upwards along the inner side of the connecting portion, a step difference is created between the upper and lower parts of the corner frame, preventing contact between the inner side of the maintenance panel and the corner frame during installation and maintenance. This allows for protection of the outer end face of the corner frame without the need for additional cushioning materials or other protective components, preventing scratches and damage that affect aesthetics, saving costs, and simplifying the operation process.

[0007] To achieve the above objectives, the first aspect of this utility model provides a scratch-resistant housing for an outdoor unit of an air conditioner, comprising:

[0008] Right rear panel;

[0009] Front panel, the front panel being disposed at the front end of the right rear panel;

[0010] A top cover, which is disposed at the upper end of the right rear panel and the front panel;

[0012] A corner frame, disposed at the upper end of the chassis, with its two sides connected to the front panel and the right rear panel respectively. The corner frame includes a first part, a connecting part, and a second part. The lower end of the first part is connected to the chassis. The connecting part extends inwardly from the top of the first part, and the second part extends upwardly from the inner side of the connecting part.

[0013] A repair panel is detachably mounted between the top cover and the corner frame, with its two sides connected to the front panel and the right rear panel, respectively, and at least a portion of the second part of the corner frame located inside the repair panel.

[0014] Optionally, the depth to which the connecting portion extends inward relative to the first part of the corner frame is no more than 10 mm.

[0015] Optionally, the first part of the corner frame, the connecting part, and the second part of the corner frame are integrally formed.

[0016] Optionally, the first part of the corner frame is parallel to the second part of the corner frame, and the connecting part is perpendicular to the first part of the corner frame and the second part of the corner frame.

[0017] Optionally, the upper end of the repair plate is provided with a mounting portion, which is located inside the top cover and is used to limit the repair plate relative to the top cover.

[0018] Optionally, along the height direction of the anti-scratch housing, the distance between the bottom end of the repair plate and the top end of the first part of the corner frame is not less than the size of the mounting part.

[0019] Optionally, the top of the second part of the corner frame is provided with an inwardly curled edge.

[0020] Optionally, the bottom end of the repair plate is provided with an inwardly curled edge.

[0021] The second aspect of this utility model provides an outdoor unit for an air conditioner, including an anti-scratch housing for an outdoor unit for an air conditioner as described in any one of the first aspects above.

[0022] Compared with the prior art, the present invention has at least the following technical effects:

[0023] By setting a step at the upper part of the corner frame, that is, the part that mates with the repair panel, a clearance shape can be formed, which can effectively avoid direct contact with the back of the repair panel during the repair and installation process.

Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0051] The first aspect of this embodiment provides a scratch-resistant housing 200 for an outdoor unit of an air conditioner, such as... Figures 2-3As shown, the scratch-resistant housing 200 includes a right rear panel 210, a front panel 220, a top cover 230, a chassis 240, corner frames 250, and a maintenance plate 260. The front panel 220 is located at the front end of the right rear panel 210. The top cover 230 is located at the upper end of the right rear panel 210 and the front panel 220, and the top ends of the right rear panel 210 and the front panel 220 are connected to the top cover 230, for example, by screws. The chassis 240 is located at the lower end of the right rear panel 210 and the front panel 220, and the bottom ends of the right rear panel 210 and the front panel 220 are connected to the chassis 240, for example, by screws. The corner frame 250 is located at the upper end of the chassis 240, and both sides of the corner frame 250 are connected to the front panel 220 and the right rear panel 210, respectively, and are connected to the front panel 220 and the right rear panel 210, for example, by screws.

[0052] Specifically, such as Figure 2 As shown, the corner frame 250 includes a first corner frame portion 251, a connecting portion 252, and a second corner frame portion 253. The lower end of the first corner frame portion 251 is connected to the chassis 240. The connecting portion 252 is configured to extend inward from the top of the first corner frame portion 251, and the second corner frame portion 253 is configured to extend upward from the inner side of the connecting portion 252. By providing the inwardly bent connecting portion 252 between the first corner frame portion 251 and the second corner frame portion 253, the upper part of the second corner frame portion 253 can be offset inward relative to the lower part of the first corner frame portion 251. Preferably, the first corner frame portion 251, the connecting portion 252, and the second corner frame portion 253 can be integrally formed to ensure the overall strength of the corner frame 250.

[0053] The maintenance plate 260 is detachably mounted between the top cover 230 and the corner frame 250. Both sides of the maintenance plate 260 are connected to the front panel 220 and the right rear panel 210, respectively, for example, detachably via screws. At least a portion of the second part 253 of the corner frame is located inside the maintenance plate 260. The portion of the second part 253 of the corner frame located inside the maintenance plate 260 may have screw holes, and corresponding positions on the maintenance plate 260 may have through holes, thereby facilitating the connection between the maintenance plate 260 and the corner frame 250.

[0054] By creating a step difference between the first part 251 and the second part 253 of the corner frame, the second part 253 of the corner frame is recessed inward relative to the first part 251 of the corner frame. This ensures the distance between the outer end face of the second part 253 of the corner frame and the maintenance plate 260 during the installation of the maintenance plate 260, thus preventing scratches and bumps that could affect the aesthetics of the corner frame 250.

[0055] Specifically, the inward extension depth of the connecting portion 252 relative to the first part 251 of the corner frame is no more than 10mm. Further, the inward extension depth of the connecting portion 252 relative to the first part 251 of the corner frame can be 3mm, thereby ensuring sufficient internal space of the anti-scratch housing 200 while adequately maintaining the distance between the outer end face of the second part 253 of the corner frame and the maintenance plate 260.

[0056] Furthermore, the second part 253 of the corner frame can be parallel to the first part 251 of the corner frame, thereby facilitating the connection strength between the second part 253 of the corner frame and the front panel 220 and the right rear panel 210. The connecting part 252 can be perpendicular to both the first part 251 and the second part 253 of the corner frame, thereby ensuring sufficient depth of inward extension of the connecting part 252 relative to the first part 251 of the corner frame, which is beneficial for cost savings. Figure 3 As shown, the top end of the second part 253 of the corner frame is provided with a corner frame rolled edge 254. The corner frame rolled edge 254 can be constructed as a rolled edge that curls inward, which is beneficial to improving the structural strength of the corner frame 250.

[0057] The upper end of the repair plate 260 is provided with a mounting part 261, which is located inside the top cover 230 and is used to limit the repair plate 260 relative to the top cover 230. The mounting part 261 and the top cover 230 may be provided with multiple through holes at corresponding positions to facilitate the connection between the repair plate 260 and the top cover 230.

[0058] Because the mounting portion 261 of the repair plate 260 needs to be inserted obliquely from bottom to top into the inner side of the top cover 230 when installing the repair plate 260, it is preferable that, along the height direction of the anti-scratch housing 200, the distance between the bottom end of the repair plate 260 and the top end of the first part 251 of the corner frame is not less than the size of the mounting portion 261. This ensures that the bottom edge of the repair plate 260 will not touch the first part 251 of the corner frame during installation. Figure 2 As shown, the maintenance plate 260 may also be provided with a handle 263, which can be used for installation and positioning, and can facilitate applying force to the maintenance plate 260.

[0059] like Figure 3 As shown, the bottom end of the repair plate 260 is provided with a repair plate rolled edge portion 262, which is constructed as an inwardly rolled edge. By taking the rolled edge form on the inside of the repair plate 260, the sheet metal cut (the cut made by the die) can be rolled inside the repair plate rolled edge portion 262, avoiding the sheet metal cut from scratching the outer end face of the corner frame 250 during the assembly process.

[0060] This embodiment also provides an outdoor air conditioning unit, which includes the scratch-resistant outer casing 200. The scratch-resistant outer casing 200 can house components such as a condenser plate, temperature sensor, cross-flow fan, compressor, four-way valve, liquid receiver, starting capacitor, and control board, thus forming a complete outdoor air conditioning unit that works in conjunction with the indoor air conditioning unit to achieve a cooling (heating) cycle. When maintenance is required on the components inside the scratch-resistant outer casing 200, the maintenance board 260 can be disassembled by personnel.

[0061] This invention creates a step difference at the upper part of the corner frame, where it mates with the repair panel, forming an avoidance shape. This effectively avoids direct contact with the back of the repair panel during the repair and installation process, eliminating the need for additional soft materials, such as adhesive tape, between the back of the repair panel and the corner frame. This reduces component costs and labor costs associated with the application process, simplifies the work, and improves work efficiency.
