Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioner technology, specifically to an air conditioner outdoor unit chassis, an air conditioner outdoor unit, and an air conditioner. Background Technology
[0002] Currently, air conditioners have gradually become necessities in people's daily lives. The outdoor unit casing of a split air conditioner includes a front panel, rear panel, left side panel, right side panel, top cover, and chassis. The chassis, which houses the compressor and other components, is the main load-bearing structure of the outdoor unit, and its strength plays a crucial role in the overall structure. Ordinary air conditioner outdoor unit chassis are prone to significant deformation during transportation due to abnormal external forces. Especially if the outdoor unit is dropped during transport, the deformation at its edges is more pronounced, affecting the product's appearance, noise level, and reliability. Utility Model Content
[0003] The first objective of this utility model is to provide an air conditioner outdoor unit chassis to solve the technical problem of large deformation of existing air conditioner outdoor unit chassis when dropped.
[0004] The first aspect of this utility model provides an air conditioner outdoor unit chassis, including a chassis body. The chassis body is provided with a first lower convex ridge and a second lower convex ridge, which intersect and are both located at the corners of the chassis body.
[0005] The beneficial effects of this utility model of an air conditioner outdoor unit chassis are:
[0006] By setting intersecting first and second lower convex ridges at the corners of the chassis body, when the outdoor unit chassis of the air conditioner is subjected to abnormal external force, such as when it falls, the corners of the outdoor unit chassis of the air conditioner will likely hit the ground first. The first and / or second lower convex ridges can be used to make contact with the object below first, so that the part with the convex shape will collide first. This part itself has greater rigidity, and its first collision can reduce the impact on the rest of the parts. In addition, the first and second lower convex ridges can also be used to increase the rigidity of the relevant area where they are set, and reduce the deformation of the relevant area.
[0007] In an optional technical solution, the first lower convex ridge and the second lower convex ridge each include a first sidewall and a second sidewall arranged at an angle, wherein the angle between the first sidewall and the second sidewall is 45° to 60°.
[0008] Setting the included angle between the two side walls of the first and second lower convex ridges to the above angle allows for an appropriate degree of protrusion. This avoids situations where the protrusion is too small to effectively reinforce the outdoor unit chassis, or where a sufficiently large protrusion would affect the chassis layout. Furthermore, it also prevents excessive protrusion from increasing the structural fragility of the protrusion itself and thus hindering rigidity improvement.
[0009] In an optional technical solution, the included angle between the first sidewall and the second sidewall is 50°.
[0010] By selecting the angle between the first and second sidewalls as shown above, it can be found that the deformation is minimized during drop tests.
[0011] In an optional technical solution, the lower end of the first sidewall of the first lower convex ridge and the lower end of the second sidewall are connected by a transition portion; and / or, the lower end of the first sidewall of the second lower convex ridge and the lower end of the second sidewall are connected by a transition portion.
[0012] By providing a transition section between the lower end of the first sidewall and the lower end of the second sidewall of the first and / or second lower convex ridges, stress concentration can be reduced, thereby improving the load-bearing capacity of the first and second lower convex ridges.
[0013] In an optional technical solution, the transition portion is a rounded corner transition portion.
[0014] The use of rounded transition sections, with no straight lines intersecting at any point in the transition section, can significantly reduce stress concentration effects, thereby improving the load-bearing capacity of the first and second lower convex ridges when encountering impact loads.
[0015] In an optional technical solution, both the first and second lower convex ridges are located at the edge of the chassis body.
[0016] Since the edge of the outdoor unit chassis usually hits the ground first, it is almost impossible for the outdoor unit chassis to land perfectly horizontally. By placing the first and second lower convex edges at the edge, the first and / or second lower convex edges can be used to directly bear the impact load.
[0017] In an optional technical solution, the second sidewall is continuously disposed on the third sidewall of the chassis body.
[0018] This configuration allows the second sidewall and the third sidewall of the chassis body to be formed simultaneously during processing, with no platform between them. The second sidewall can share the pressure with the entire third sidewall, thereby improving the load-bearing capacity of the first and second lower convex ridges.
[0019] In an optional technical solution, the outdoor unit chassis of the air conditioner is used to install the compressor, and the chassis body is provided with at least six downward protruding bosses, which are arranged around the circumference of the compressor.
[0020] This design adds a set of three protrusions for mounting the compressor feet, allowing for more flexible compressor placement and accommodating a wider range of compressor models, thus broadening the applicability of the air conditioner outdoor unit chassis.
[0021] The second objective of this utility model is to provide an outdoor air conditioner unit to solve the technical problem of large deformation of the outdoor air conditioner unit chassis when it falls.
[0022] The second aspect of this utility model provides an outdoor air conditioner unit, which includes an outdoor unit housing, wherein the outdoor unit housing includes an outdoor air conditioner chassis as described above and a side plate connected to the outdoor air conditioner chassis.
[0023] By installing the aforementioned air conditioner outdoor unit chassis in the air conditioner outdoor unit, the air conditioner outdoor unit accordingly possesses all the advantages of the aforementioned air conditioner outdoor unit chassis, which will not be elaborated upon here.
[0024] The third aspect of this utility model aims to provide an air conditioner that solves the technical problem of large deformation when the outdoor unit chassis of an air conditioner falls.
[0025] The air conditioner provided in the third aspect of this utility model includes an indoor unit and an outdoor unit, wherein the outdoor unit is connected to the indoor unit via a refrigerant connection pipe.
[0026] By installing the aforementioned outdoor unit in the air conditioner, the air conditioner accordingly possesses all the advantages of the aforementioned outdoor unit, which will not be elaborated upon here. Attached Figure Description

[0037] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.
[0038] Example 1:
[0039] Figure 1 A schematic diagram of the structure of the outdoor unit chassis of the air conditioner provided in the embodiment of this utility model. Figure 2 This is a schematic diagram of the structure of the outdoor unit chassis of the air conditioner provided in an embodiment of the present invention, viewed from another direction. Figure 3 for Figure 1 AA sectional view. For example... Figures 1-3 As shown, the air conditioner outdoor unit chassis provided in Embodiment 1 of this utility model includes a chassis body 10. The chassis body 10 is provided with a first lower protruding ridge 20 and a second lower protruding ridge 30. The first lower protruding ridge 20 and the second lower protruding ridge 30 intersect and are both located at the corners of the chassis body 10.
[0040] By setting intersecting first lower convex ribs 20 and second lower convex ribs 30 at the corners of the chassis body 10, when the outdoor unit chassis of the air conditioner is subjected to abnormal external force, such as when it falls, the corners of the outdoor unit chassis of the air conditioner will likely hit the ground first. The first lower convex ribs 20 and / or the second lower convex ribs 30 can make contact with the object below first, thereby using the part with the convex shape to collide first. This part itself has greater rigidity, and its first collision can reduce the impact on the rest. In addition, the first lower convex ribs 20 and the second lower convex ribs 30 can also be used to increase the rigidity of the relevant area where they are set, and reduce the deformation of the relevant area.
[0041] Viewed from either a top or bottom angle, the chassis of the air conditioner outdoor unit is roughly rectangular. In this embodiment, the first lower protruding ridge 20 and the second lower protruding ridge 30 are distributed in one corner area of the roughly rectangular air conditioner outdoor unit chassis. Of course, in other implementations, the first lower protruding ridge 20 and the second lower protruding ridge 30 can be distributed in multiple corner areas or all corner areas of the air conditioner outdoor unit chassis.
[0042] Specifically, in this embodiment, both the first lower convex ridge 20 and the second lower convex ridge 30 protrude downwards, so the lower parts of the first lower convex ridge 20 and the second lower convex ridge 30 can bear the load first. The internal spaces of the first lower convex ridge 20 and the second lower convex ridge 30 can be connected. That is, the first lower convex ridge 20 and the second lower convex ridge 30, located in the same corner region, can be L-shaped as a whole or have a chamfered L-shape at the corner.
[0043] like Figure 3 As shown, optionally, the first lower convex ridge 20 and the second lower convex ridge 30 each include a first sidewall 21 and a second sidewall 22 arranged at an angle, the angle between the first sidewall 21 and the second sidewall 22 being 45°~60°.
[0044] Setting the included angle between the two side walls of the first lower convex rib 20 and the second lower convex rib 30 to the above angle allows for an appropriate degree of protrusion. This avoids situations where the protrusion is too small to effectively reinforce the outdoor unit chassis, or where a sufficiently large protrusion would affect the layout of the outdoor unit chassis. Furthermore, it also avoids situations where an excessively large protrusion would increase the fragility of the protruding structure itself, thus affecting the improvement of rigidity.
[0045] Specifically, such as Figure 4 As shown, with other variables remaining constant, when the included angle is 45°, the deformation at the corner where the first sidewall 21 and the second sidewall 22 are located is about 9.5 mm, while when the included angle is 60°, the deformation is about 8.4 mm.
[0046] Specifically, in this embodiment, the second sidewall 22 is closer to the edge of the outdoor unit chassis, while the first sidewall 21 is closer to the center of the outdoor unit chassis. When the outdoor unit chassis is placed horizontally, the first sidewall 21 and the second sidewall 22 can form angles of 60° to 70° with the horizontal plane, respectively. More specifically, they can form an angle of 65°.
[0047] like Figure 3 As shown, optionally, the included angle between the first sidewall 21 and the second sidewall 22 is 50°.
[0048] By selecting the angle between the first sidewall 21 and the second sidewall 22 as the above angle, it can be found that the deformation is minimal when conducting drop tests.
[0049] like Figure 4 As shown, when the included angle is 50°, the deformation during the drop test is approximately 7.6 mm.
[0050] like Figure 3 As shown, optionally, the lower end of the first sidewall 21 and the lower end of the second sidewall 22 of the first lower convex ridge 20 are connected by a transition portion 23; the lower end of the first sidewall 21 and the lower end of the second sidewall 22 of the second lower convex ridge 30 are connected by a transition portion 23.
[0051] By providing a transition portion 23 between the lower end of the first sidewall 21 and the lower end of the second sidewall 22 of the first lower convex ridge 20 and / or the second lower convex ridge 30, stress concentration can be reduced, thereby improving the load-bearing capacity of the first lower convex ridge 20 and the second lower convex ridge 30.
[0052] like Figure 3 As shown, optionally, the transition portion 23 is a rounded corner transition portion.
[0053] The use of rounded transition sections, with no straight lines intersecting at any position of the transition section 23, can significantly reduce the stress concentration effect, thereby improving the load-bearing capacity of the first lower convex rib 20 and the second lower convex rib 30 when encountering impact loads.
[0054] like Figures 1-3 As shown, optionally, the first lower convex ridge 20 and the second lower convex ridge 30 are both located at the edge of the chassis body 10.
[0055] Since the edge of the outdoor unit chassis usually hits the ground first, it is almost impossible for the outdoor unit chassis to land perfectly horizontally. By placing the first lower convex rib 20 and the second lower convex rib 30 at the edge, the first lower convex rib 20 and / or the second lower convex rib 30 can be used to directly bear the impact load.
[0056] The first lower convex ridge 20 is located on the long side of the roughly rectangular chassis body 10, while the second lower convex ridge 30 is located on the short side of the chassis body 10. The length of the first lower convex ridge 20 is approximately 1 / 15 to 1 / 10 of the length of the long side; while the length of the second lower convex ridge 30 is approximately 1 / 3 to 1 / 2 of the length of the short side.
[0057] like Figures 1-3 As shown, optionally, the second sidewall 22 is continuously disposed on the third sidewall 11 of the chassis body 10.
[0058] This configuration allows the second sidewall 22 and the third sidewall 11 of the chassis body 10 to be formed simultaneously during processing, and there is no platform between them. The second sidewall 22 can share the pressure with the third sidewall 11 as a whole, thereby improving the load-bearing capacity of the first lower convex rib 20 and the second lower convex rib 30.
[0059] In order to improve the rigidity of its edge portion, the chassis body 10 has a third sidewall 11 at its edge. The second sidewall 22 of the first lower convex ridge 20 and the second lower convex ridge 30, that is, the sidewalls of the two located on the outside, can be continuously provided with the third sidewall 11. More specifically, the second sidewall 22 and the third sidewall 11 can be smoothly transitioned.
[0060] like Figure 1 and Figure 2 As shown, optionally, the outdoor unit chassis of the air conditioner is used to install the compressor (not shown in the figure), and the chassis body 10 is provided with at least six downward protruding bosses 40, which are arranged around the compressor.
[0061] This design adds a set of three protrusions 40 for mounting the compressor feet, allowing for more flexible placement of the compressor and accommodating a wider range of compressor models, thus broadening the applicability of the outdoor unit chassis of this air conditioner.
[0062] In the prior art, three downwardly protruding bosses 40 are arranged on the chassis body 10. The three bosses 40 are evenly distributed around the circumference of the compressor to install the compressor's feet. "Evenly distributed around the circumference" means that the center of each of the three bosses 40 is at the same angle to the center of the circle, more specifically, 120°. In this embodiment, an additional set of three downwardly protruding bosses 40 is added, and this set of three downwardly protruding bosses 40 is also evenly distributed around the circumference.
[0063] Example 2:
[0064] Embodiment 2 also provides an outdoor air conditioner unit, including an outdoor unit housing, the outdoor unit housing including the outdoor unit chassis of any of the above and a side plate connected to the outdoor unit chassis.
[0065] By installing the aforementioned air conditioner outdoor unit chassis in the air conditioner outdoor unit, the air conditioner outdoor unit accordingly possesses all the advantages of the aforementioned air conditioner outdoor unit chassis, which will not be elaborated upon here.
[0066] Example 3:
[0067] Embodiment 3 also provides an air conditioner, including an indoor unit and the aforementioned outdoor unit, wherein the outdoor unit is connected to the indoor unit via a refrigerant connection pipe.
[0068] By installing the aforementioned outdoor unit in the air conditioner, the air conditioner accordingly possesses all the advantages of the aforementioned outdoor unit, which will not be elaborated upon here.

Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
