Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to a top cover plate and an outdoor unit of an air conditioner. Background Art

[0002] The outdoor unit of the air conditioner is exposed to the outdoor environment and is usually installed on the outdoor wall. Compared with the indoor unit, the environment in which the outdoor unit is located is harsher, and foreign objects often fall on the top cover of the shell. For this reason, the top cover needs to have sufficient structural strength.

[0003] However, in the prior art, the top cover of the air conditioner outdoor unit is usually a flat plate with limited structural strength and is easily deformed. Utility Model Content

[0004] The first purpose of the utility model is to provide a top cover plate to solve the technical problems in the prior art that the top cover plate of the air conditioner outdoor unit casing has insufficient structural strength and is easily deformed.

[0005] The top cover plate provided by the present invention includes a plate body, which is rectangular and includes a plurality of mutually parallel oblique reinforcing ribs. The oblique reinforcing ribs include a first reinforcing rib and a second reinforcing rib. The first reinforcing rib is obliquely arranged between the long side and the wide side of the plate body, and the second reinforcing rib is obliquely arranged between the two long sides of the plate body.

[0006] The top cover provided by the utility model can produce the following beneficial effects:

[0007] The top cover plate provided by the present invention is provided with a plurality of mutually parallel oblique reinforcing ribs. Compared with providing a plurality of mutually parallel reinforcing ribs along the length direction or width direction of the top cover plate, not only the number of the reinforcing ribs is increased, but also the oblique reinforcing ribs can simultaneously improve the structural strength of the top cover plate in the length direction and the width direction, thereby improving the structural strength of the top cover plate. Among them, the first reinforcing ribs can improve the structural strength of the triangular area surrounded by the wide side and part of the long side of the top cover plate, and all the second reinforcing ribs can improve the structural strength of the parallelogram area occupied by them. As the structural strength is improved, the supporting capacity of the top cover plate is improved, so it is not easy to deform.

[0008] Furthermore, the two ends of the first reinforcing rib pass through the corresponding long side and the wide side, and the two ends of the second reinforcing rib pass through the corresponding two long sides. Under this technical solution, rainwater can be collected in the low-lying areas of the board body and discharged from the edge of the top cover, making it difficult for water to accumulate on the top cover.

[0009] Optionally, the two ends of the first reinforcing rib are respectively close to the corresponding long side and the wide side, and the two ends of the second reinforcing rib are respectively close to the two corresponding long sides. Under this technical solution, it is convenient to set a flange on the edge of the top cover. Moreover, if the first and second reinforcing ribs both protrude from the flat portion of the plate body, that is, the flat portion of the plate body is the lowest part of the plate body, rainwater can be drained smoothly and water is not easily accumulated on the top cover.

[0010] Furthermore, the length of the long side corresponding to the first reinforcing rib accounts for 2 / 7 to 1 / 2 of its total length.

[0011] Furthermore, the angle between the oblique reinforcing rib and the long side is 33° to 48° or 132° to 147°, preferably 45° or 135°. Under this technical solution, each first reinforcing rib provides balanced support to its corresponding long side and short side, making the top cover less likely to deform.

[0012] Furthermore, the oblique reinforcing ribs have a wavy cross-section, comprising an upwardly projecting convex portion and a downwardly projecting concave portion. Furthermore, between two adjacent oblique reinforcing ribs, the concave portion of one oblique reinforcing rib smoothly transitions to the convex portion of the other. With this technical solution, the oblique reinforcing ribs form the body of the roof panel, resulting in smooth, natural connections throughout the entire panel, relatively uniform structural strength, and significantly reducing stress concentration.

[0013] Optionally, the oblique reinforcing ribs are upwardly protruding ribs, with two adjacent ribs spaced apart. In this technical solution, the oblique reinforcing ribs protrude from the flat portion of the plate body, which is the lowest portion of the plate body. Rainwater can be drained away smoothly, and water is not easily accumulated on the top cover.

[0014] Further, at least one of the first reinforcing ribs is provided with a first anti-foolproof protrusion at one end corresponding to the long side; or, at least one of the second reinforcing ribs is provided with a second anti-foolproof protrusion at one end; or, at least one of the first reinforcing ribs is provided with the first anti-foolproof protrusion at one end corresponding to the long side, and at least one of the second reinforcing ribs is provided with the second anti-foolproof protrusion at one end, and the first anti-foolproof protrusion and the second anti-foolproof protrusion correspond to the same long side.

[0015] Under this technical solution, during assembly, the position of the anti-mistake protrusion can be used to identify the installation direction of the top cover plate. For example, the long side corresponding to the anti-mistake protrusion is the front side of the top cover plate, that is, during installation, the long side corresponding to the anti-mistake protrusion faces forward. Preferably, all first reinforcing ribs are provided with a first anti-mistake protrusion at one end corresponding to the long side, and all second reinforcing ribs are provided with a second anti-mistake protrusion at one end, and the first and second anti-mistake protrusions correspond to the same long side.

[0016] Furthermore, the edge of the plate body is provided with a downwardly folded flange; part of the wide side of the plate body extends outward to form a hand-digging portion, and the oblique reinforcing ribs extend to the hand-digging portion.

[0017] With this technical solution, the flap allows the top cover to fit over the tops of the front, left, right, and rear panels of the air conditioner's outdoor unit housing, effectively limiting the position of the panels while also effectively preventing rainwater from entering the housing through the gaps between the top cover and the panels. The handle also provides significant convenience for lifting and moving the entire outdoor unit.

[0018] The second purpose of the present invention is to provide an air conditioner outdoor unit to solve the technical problem in the prior art that the top cover plate of the air conditioner outdoor unit shell is not strong enough and is easily deformed.

[0019] The air conditioner outdoor unit provided by the present invention includes a shell, which includes a base and a front panel, a left panel, a right panel and a rear wall panel arranged on the base, and also includes the above-mentioned top cover plate, which is fixedly connected to the tops of the front panel, the left panel, the right panel and the rear wall panel.

[0020] The air conditioner outdoor unit provided by the present invention has all the advantages of the above-mentioned top cover plate, so they will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] This embodiment provides a top cover plate 100, such as Figure 1 as well as Figures 4 to 8 As shown, the top cover plate 100 includes a plate body 110, which is rectangular. The plate body 110 includes a plurality of mutually parallel oblique reinforcing ribs, the oblique reinforcing ribs including a first reinforcing rib 111 and a second reinforcing rib 112. The first reinforcing rib 111 is obliquely arranged between the long side and the wide side of the plate body 110, and the second reinforcing rib 112 is obliquely arranged between the two long sides of the plate body 110.

[0036] The top cover plate 100 provided in this embodiment is provided with a plurality of mutually parallel oblique reinforcing ribs. Compared with providing a plurality of mutually parallel reinforcing ribs along the length direction or width direction of the top cover plate 100, not only the number of the reinforcing ribs is increased, but also the oblique reinforcing ribs can simultaneously improve the structural strength of the top cover plate 100 in the length direction and the width direction, thereby improving the structural strength of the top cover plate 100. Among them, the first reinforcing ribs 111 can improve the structural strength of the triangular area surrounded by the wide side and part of the long side of the top cover plate 100, and all the second reinforcing ribs 112 can improve the structural strength of the parallelogram area occupied by them. As the structural strength increases, the supporting capacity of the top cover plate 100 is improved, so it is not easy to deform.

[0037] Specifically, the top cover plate 100 provided in this embodiment has a variety of different forms, which are classified based on whether the two ends of the oblique reinforcement ribs pass through the corresponding edges. Figure 1 as well as Figures 4 to 6 The oblique reinforcement ribs extend through the corresponding edges. That is, the ends of the first reinforcement rib 111 extend through its corresponding long and wide edges, and the ends of the second reinforcement rib 112 extend through its corresponding two long edges. This arrangement allows rainwater to collect in the low-lying areas of the plate 110 and drain from the edges of the roof panel 100, preventing water from accumulating on the roof panel 100.

[0038] Figure 7 and Figure 8 The diagram shows a configuration where the oblique reinforcement ribs do not extend through the corresponding edges. That is, the two ends of the first reinforcement rib 111 are respectively adjacent to its corresponding long side and wide side, while the two ends of the second reinforcement rib 112 are respectively adjacent to its corresponding two long sides. This configuration facilitates the installation of flanges 130 on the edge of the top cover 100. Furthermore, if the first and second reinforcement ribs 111, 112 both protrude from the flat portion of the plate body 110, i.e., the flat portion of the plate body 110 is the lowest portion of the plate body 110, rainwater can be drained smoothly, and water accumulation on the top cover 100 is less likely to occur.

[0039] Specifically, in this embodiment, the length of the long side corresponding to the first reinforcing rib 111 accounts for 2 / 7 to 1 / 2 of its total length. That is, 2 / 7 to 1 / 2 of the long side and the wide side share the load. The specific ratio can be determined based on the aspect ratio of the top cover plate 100. In fact, when the oblique reinforcing ribs are evenly arranged, the above ratio is consistent with the ratio of the number of first reinforcing ribs 111 to the total number of oblique reinforcing ribs.

[0040] Specifically, in this embodiment, the angle between the oblique reinforcement rib and the long side is 33° to 48° or 132° to 147°, preferably 45° or 135°. Figure 1 as well as Figure 7 and Figure 8 The angle between the oblique reinforcement rib and the long side is 45°. Figures 4 to 6 The angle between the oblique reinforcement rib and the long side is 135 degrees. In this arrangement, each first reinforcement rib 111 provides a more balanced support to the corresponding long side and short side, and the top cover plate 100 is less likely to deform.

[0041] Preferably, in this embodiment, the number of the second reinforcing ribs 112 is similar to that of the first reinforcing ribs 111. More preferably, the number of the second reinforcing ribs 112 is the same. Specifically, in this embodiment, the aspect ratio of the top cover plate 100 is 3:1, and the inclination angles of the first reinforcing ribs 111 and the second reinforcing ribs 112 are 45° or 135°. Figures 1 to 6In the top cover plate 100 shown, the number of the first reinforcing ribs 111 and the number of the second reinforcing ribs 112 are the same, both 16; Figure 7 and Figure 8 In the top cover plate 100 shown, there are 6 first reinforcing ribs 111 and 7 second reinforcing ribs 112, which are similar in number.

[0042] Specifically, in this embodiment, the cross-sectional shape of the plate 110 or the oblique reinforcing ribs is used as the basis, and the oblique reinforcing ribs may also have different forms, such as Figure 2 and Figure 3 As shown, the cross-section of the oblique reinforcing ribs can be wavy, or a continuous arch, comprising an upwardly protruding convex rib portion 113 and a downwardly protruding concave rib portion 114. In addition, between two adjacent oblique reinforcing ribs, the concave rib portion 114 of one oblique reinforcing rib smoothly transitions to the convex rib portion 113 of the other oblique reinforcing rib. With this arrangement, the oblique reinforcing ribs form the body 110 of the top cover 100, creating smooth, natural connections throughout the body 110, resulting in relatively uniform structural strength and significantly reducing stress concentration.

[0043] More specifically, in this embodiment, Figure 3 As shown, the radius R of the convex rib 113 is 12 mm, the radius r of the concave rib 114 is 5 mm, and the height h of the plate body 110 is 6 mm. Of course, in other embodiments of the present application, the radius R of the convex rib 113, the radius r of the concave rib 114, and the height h of the plate body 110 are not limited to the above values, and other values ​​may also be used.

[0044] Based on the cross-sectional shape of the plate 110 or the oblique reinforcing rib, the oblique reinforcing rib can also be a convex rib protruding upward, with two adjacent convex ribs spaced apart, such as Figure 7 and Figure 8 In this arrangement, the oblique reinforcement ribs protrude from the flat portion of the plate body 110, which is the lowest portion of the plate body 110. Rainwater can be drained away smoothly, and water is not easily accumulated on the top cover plate 100.

[0045] Specifically, in this embodiment, at least one first reinforcing rib 111 is provided with a first fool-proof protrusion (not shown in the figure) at one end corresponding to the long side; or, at least one second reinforcing rib 112 is provided with a second fool-proof protrusion (not shown in the figure); or, at least one first reinforcing rib 111 is provided with a first fool-proof protrusion at one end corresponding to the long side, and at least one second reinforcing rib 112 is provided with a second fool-proof protrusion at one end, and the first fool-proof protrusion and the second fool-proof protrusion correspond to the same long side. In this arrangement, during assembly, the installation direction of the top cover plate 100 can be identified by the location of the fool-proof protrusion. For example, the long side corresponding to the fool-proof protrusion is the front side of the top cover plate 100, that is, during installation, the long side corresponding to the fool-proof protrusion faces forward.

[0046] More specifically, in this embodiment, all the first reinforcing ribs 111 are provided with a first anti-foolproof protrusion at one end corresponding to the long side, and all the second reinforcing ribs 112 are provided with a second anti-foolproof protrusion at one end, and the first anti-foolproof protrusion and the second anti-foolproof protrusion correspond to the same long side. For example, the first anti-foolproof protrusion and the second anti-foolproof protrusion are respectively provided at the front end of the first reinforcing rib 111 and the front end of the second reinforcing rib 112, that is, the first anti-foolproof protrusion and the second anti-foolproof protrusion both correspond to the front edge of the top cover plate 100.

[0047] As for the specific structural form of the fool-proof protrusion, it can be a convex point, of course, it can also be other shapes, and it can also be an inwardly protruding groove, as long as it can be distinguished from the other end of the oblique reinforcement rib.

[0048] Specifically, in this embodiment, the edge of the plate body 110 is provided with a downwardly folded flange 130; a portion of the wide edge of the plate body 110 extends outward to form a hand-holding portion 120, and diagonal reinforcing ribs extend to the hand-holding portion 120. With this arrangement, the flange 130 allows the top cover 100 to cover the tops of the vertical panels of the air conditioner outdoor unit housing, including the front panel 200, left panel, right panel, and rear wall panel. This not only limits the position of each vertical panel, but also effectively prevents rainwater and other substances from entering the housing through the gaps between the top cover 100 and the vertical panels. The provision of the hand-holding portion 120 greatly facilitates lifting and moving the entire air conditioner outdoor unit.

[0049] In summary, the top cover plate 100 provided in this embodiment has a variety of specific forms. The oblique reinforcing ribs of the top cover plate 100 may pass through the corresponding edges or may not pass through the corresponding edges; the cross-section of the oblique reinforcing ribs may be wavy, or the oblique reinforcing ribs may only include upwardly protruding ribs; the angle between the oblique reinforcing ribs and the long sides may be 45°, 135° or other angles, and the above situations can be freely combined. Figure 1 The top cover plate 100 shown has oblique reinforcement ribs running through the corresponding sides, a wavy cross section, and an angle of 45° with the long side. Figures 4 to 6 In the example, the oblique reinforcement ribs of the top cover plate 100 pass through the corresponding edges, the cross section is wavy, and the angle between the cross section and the long side is 135°. Figure 7 and Figure 8 The illustrated top cover plate 100 has oblique reinforcement ribs that do not extend through the corresponding sides, but consist only of upwardly projecting ribs at a 45° angle to the long sides. Regardless of the above configuration, because all of the above oblique reinforcement ribs are numerous and reinforce the plate body 110 in both the longitudinal and width directions, the structural strength of these top cover plates 100 is relatively high and they are not easily deformed.

[0050] right Figures 4 to 6 The top cover plate 100 shown in FIG. 1 and the top cover plates with general planar ribs and transverse arched ribs are subjected to impact simulation. The results are shown in FIG. Figure 9As shown, it can be seen that the top cover plate 100 with oblique arched ribs provided in this embodiment has the smallest deformation, and the radius of its deformation area is only about 14 mm, which is smaller than the other two forms, and the improvement ratio is 17.65%, which is much larger than the other two forms, that is, the oblique arched ribs show better mechanical properties when subjected to top surface impact.

[0051] This embodiment also provides an air-conditioning outdoor unit, which includes a shell, the shell includes a base 300 and a front panel 200, a left side panel, a right side panel and a rear wall panel arranged on the base 300, and also includes the above-mentioned top cover plate 100, and the top cover plate 100 is fixedly connected to the tops of the front panel 200, the left side panel, the right side panel and the rear wall panel.

[0052] The air conditioner outdoor unit provided in this embodiment has all the advantages of the top cover plate 100 described above, so they will not be described in detail here.
