Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to a rear panel assembly and an air conditioner cabinet having the same. Background Technology

[0002] With economic development and the continuous improvement of living standards, air conditioners are becoming increasingly widely used. Air conditioners typically consist of an indoor unit and an outdoor unit. Based on usage type, indoor units can be divided into wall-mounted units and floor-standing units. Floor-standing units usually have a maintenance access panel on their rear panel, with a closable wiring cover. Opening the wiring cover allows for maintenance of the internal structure of the unit and also facilitates after-sales personnel connecting the power cord to the indoor unit.

[0003] However, in the use of existing air conditioner cabinet units, there is a problem where the wiring cover and the rear panel do not fit tightly, resulting in a large gap between the wiring cover and the rear panel. Summary of the Invention

[0004] The first objective of this invention is to provide a rear panel assembly to solve the technical problem that existing air conditioning cabinet units have a problem where the wiring cover and the rear panel do not fit tightly, resulting in a large gap between the wiring cover and the rear panel.

[0005] The rear panel assembly provided by the present invention includes a rear panel with a maintenance opening, wherein a wiring cover is provided at the maintenance opening, wherein the rear panel has a mounting surface facing the wiring cover, the wiring cover has a mating surface facing the rear panel, and one of the mounting surface and the mating surface is provided with a rib, the rib being configured to cooperate with the other of the mounting surface and the mating surface.

[0006] By providing ribs on the mating surface of the wiring cover facing the rear panel, or on the mounting surface of the rear panel facing the wiring cover, a ribbed surface contact fit is formed between the wiring cover and the rear panel after assembly, ensuring a tight fit between them. This design effectively improves upon the issue of incomplete fit caused by surface-to-surface contact in existing technologies, thus avoiding the technical problem of large gaps between the wiring cover and the rear panel during use of the air conditioner unit. Furthermore, this ribbed surface fit method eliminates the need to machine the entire surface of the component with the ribs, saving on manufacturing costs.

[0007] Furthermore, the ribs are disposed on the mating surface. By disposing the ribs on the mating surface, that is, by disposing the ribs on the wiring cover, not only can the structural strength of the wiring cover be improved and the risk of damage to the wiring cover during repeated disassembly and assembly be reduced, but the manufacturing process of the rear panel can also be simplified, thereby facilitating the processing and manufacturing of the rear panel.

[0008] Furthermore, the ribs are distributed on a set of opposite sides of the wiring cover. This arrangement ensures that after the wiring cover is installed on the rear panel, a set of opposite sides can fit against the mounting surface of the rear panel through the interaction of the ribs, further guaranteeing a tight fit between the wiring cover and the rear panel.

[0009] Furthermore, the wiring cover has a centerline extending along the height direction of the rear panel, and the set of opposite sides are edges located on both sides of the centerline. This arrangement reduces interference with the wiring cover assembly structure.

[0010] Furthermore, each of the two edges of the set of opposite sides is provided with multiple ribs, and the multiple ribs provided on each edge are arranged at intervals along the direction of the corresponding edge. Through the above arrangement, the number of mating points between the wiring cover and the mounting surface of the rear panel can be increased, thereby increasing the reliability of the fit between the wiring cover and the rear panel.

[0011] Furthermore, the extension directions of the ribs set on the two edges of the set of opposite sides are both at an angle to the direction of the corresponding edge. This arrangement reduces the space occupied by each rib along the direction of the corresponding edge, thereby facilitating an increase in the number of ribs set on each edge.

[0012] Furthermore, a limiting flange is provided inside the maintenance opening. The limiting flange is distributed along the edge of the maintenance opening and forms a stepped structure with the outer surface of the rear panel. The side of the limiting flange facing the wiring cover plate forms the mounting surface, allowing the wiring cover plate to be fitted into the maintenance opening. This design serves two purposes: firstly, it limits the assembly stroke of the wiring cover plate during installation into the maintenance opening, preventing over-installation and damage to the internal structure of the air conditioner unit; secondly, it allows the wiring cover plate to be fitted into the maintenance opening, thereby limiting its movement and preventing it from moving in the up, down, left, or right directions.

[0013] Furthermore, the edge of the wiring cover is provided with a snap fastener, and the rear panel has an insertion hole. The snap fastener can be inserted into the insertion hole, wherein at least one gate of the wiring cover is located in the snap fastener. This arrangement can at least partially conceal the gate of the wiring cover, ensuring the flatness of the air conditioner cabinet to a certain extent and improving its aesthetics.

[0014] Furthermore, the snap-fit ​​is located at the lower edge of the wiring cover plate, and the gates of the wiring cover plate are also distributed at its upper edge, left edge, and right edge. This arrangement increases the distribution range of the gates on the wiring cover plate, thereby facilitating the molding of the wiring cover plate.

[0015] The second objective of this invention is to provide an air conditioner cabinet unit that solves the technical problem that existing air conditioner cabinet units have a problem with the wiring cover not fitting tightly with the rear panel, resulting in a large gap between the wiring cover and the rear panel.

[0016] The air conditioner cabinet unit provided by the present invention includes the aforementioned rear panel assembly.

[0017] By incorporating the aforementioned rear panel assembly into the air conditioning unit, the air conditioning unit thus possesses all the advantages of the aforementioned rear panel assembly, which will not be elaborated upon here. Attached Figure Description

[0027] Currently, the wiring cover is directly attached to the rear panel, meaning that the wiring cover is installed to the rear panel through surface-to-surface contact. However, the surfaces of the wiring cover and the rear panel are easily affected by the processing technology, resulting in uneven surfaces after processing. This causes gaps during surface-to-surface contact, resulting in poor fit and a large gap between the wiring cover and the rear panel.

[0028] 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. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0029] Figure 1 This is an exploded view of the air conditioner unit provided in this embodiment. Figure 1 As shown, this embodiment provides a rear panel assembly, including a rear panel 100 with a maintenance opening 110, and a wiring cover 200 is provided at the maintenance opening 110 in an openable and closable manner.

[0030] Figure 2 This is a structural schematic diagram of the rear panel 100 of the air conditioner unit provided in this embodiment. Figure 3 for Figure 2 Enlarged view of the local structure at point A in the middle. Figure 4 This is a structural schematic diagram of the wiring cover 200 of the air conditioner cabinet unit provided in this embodiment. Please continue to refer to... Figure 1 and combined Figures 2 to 4 The rear panel 100 has a mounting surface 120 facing the wiring cover 200, and the wiring cover 200 has a mating surface 210 facing the rear panel 100, wherein the mating surface 210 is provided with ribs 220, and the ribs 220 are configured to cooperate with the mounting surface 120.

[0031] By providing ribs 220 on the side of the wiring cover 200 facing the rear panel 100, the wiring cover 200, after being assembled to the rear panel 100, can fit against the mounting surface 120 of the rear panel 100 through the ribs 220, forming a rib-surface contact fit between the wiring cover 200 and the rear panel 100, thus ensuring a tight fit between the wiring cover 200 and the rear panel 100. This design effectively improves the situation of incomplete fit caused by surface contact fit between the wiring cover 200 and the rear panel 100 in the prior art, thereby avoiding the technical problem of large gaps between the wiring cover 200 and the rear panel 100 during the use of the air conditioner cabinet unit. Moreover, this rib-surface fit method eliminates the need to process the entire surface of the contact surface 210, thus saving processing costs.

[0032] In addition, by setting the rib 220 on the mating surface 210, that is, by setting the rib 220 on the wiring cover 200, not only can the structural strength of the wiring cover 200 be improved and the risk of damage to the wiring cover 200 during repeated disassembly and assembly be reduced, but the manufacturing process of the rear panel 100 can also be simplified, thereby facilitating the processing and manufacturing of the rear panel 100.

[0033] In other embodiments, the rib 220 can also be provided on the mounting surface 120 of the rear panel 100. In this case, after the wiring cover 200 is assembled in place, the rib surface cooperation between the wiring cover 200 and the rear panel 100 can also achieve a tight fit between the two.

[0034] Please continue to refer to Figure 4 In this embodiment, the ribs 220 are distributed on a set of opposite sides of the wiring cover plate 200.

[0035] By providing the aforementioned ribs 220 on a set of opposite sides of the wiring cover 200, after the wiring cover 200 is installed on the rear panel 100, a set of opposite sides can fit against the mounting surface 120 of the rear panel 100 through the rib surface cooperation, thereby effectively avoiding the situation of poor fit caused by the edge of the wiring cover 200 lifting up, and further ensuring the tightness of the fit between the wiring cover 200 and the rear panel 100.

[0036] Please continue to refer to Figure 4 In this embodiment, the wiring cover 200 has a centerline 280 extending along the height direction of the rear panel 100, and the aforementioned pair of opposite sides are the edges respectively disposed on both sides of the centerline 280. That is, the ribs 220 are disposed on the left edge 230 and the right edge 240 of the wiring cover 200.

[0037] By placing the ribs 220 on the left edge 230 and right edge 240 of the wiring cover 200, interference with the assembly structure of the wiring cover 200 can be reduced.

[0038] Please continue to refer to Figure 4 In this embodiment, the left edge 230 and the right edge 240 of the wiring cover plate 200 are provided with a plurality of ribs 220, and the plurality of ribs 220 provided on the left edge 230 are arranged at intervals along the direction of the left edge 230, and the plurality of ribs 220 provided on the right edge 240 are arranged at intervals along the direction of the right edge 240.

[0039] The above settings increase the number of mating points between the wiring cover 200 and the mounting surface 120 of the rear panel 100, thereby increasing the reliability of the fit between the wiring cover 200 and the rear panel 100.

[0040] In this embodiment, the ribs 220 located on the left edge 230 and the ribs 220 located on the right edge 240 are mirror images of each other with the center line 280 as the mirror axis. This arrangement ensures that the left edge 230 and the right edge 240 of the wiring cover 200 are in stress balance.

[0041] Please continue to refer to Figure 1 In this embodiment, the air conditioner cabinet unit is approximately cylindrical in shape, that is, the shape of the rear panel 100 is close to a cylindrical surface, and the shape of the wiring cover 200 is also close to a cylindrical surface.

[0042] Please continue to refer to Figure 4 In this embodiment, the extension direction of the rib 220 provided on the left edge 230 is perpendicular to the direction of the left edge 230; the extension direction of the rib 220 provided on the right edge 240 is perpendicular to the direction of the right edge 240.

[0043] This arrangement reduces the space occupied by each rib 220 along its corresponding edge, thereby increasing the number of ribs 220 located at each edge.

[0044] In other embodiments, the extension direction of the rib 220 disposed on the left edge 230 may be set to form other angles with the left edge 230. Similarly, the extension direction of the rib 220 disposed on the right edge 240 may be set to form other angles with the right edge 240.

[0045] Please continue to refer to Figure 3 In this embodiment, a limiting flange is provided inside the maintenance port 110. The limiting flange is distributed along the edge of the maintenance port 110. The limiting flange and the outer surface of the rear panel 100 form a stepped structure. The side of the limiting flange facing the wiring cover 200 forms a mounting surface 120. The wiring cover 200 can be fitted into the maintenance port 110.

[0046] With the above settings, on the one hand, the assembly stroke of the wiring cover 200 can be limited by the limiting flange during the installation of the wiring cover 200 to the maintenance port 110, so as to avoid over-installation of the wiring cover 200 and damage to the internal structure of the air conditioner cabinet. On the other hand, the wiring cover 200 can be embedded in the maintenance port 110, so as to limit the wiring cover 200 by the maintenance port 110 and prevent the wiring cover 200 from moving in the up, down, left and right directions.

[0047] In this embodiment, when the wiring cover 200 is assembled, its outer surface is coplanar with the outer surface of the rear panel 100. That is, when the wiring cover 200 is assembled, it is completely embedded in the maintenance opening 110. This arrangement ensures the neat appearance of the air conditioner unit, thereby improving the user experience.

[0048] Please continue to refer to Figure 1 and Figure 4 In this embodiment, the edge of the wiring cover 200 is provided with a buckle 270, and the rear panel 100 is provided with a socket 130. The buckle 270 can be inserted into the socket 130. At least one gate of the wiring cover 200 is provided in the buckle 270.

[0049] By setting the gate of the wiring cover 200 in the snap fastener 270, after the wiring cover 200 is installed in the rear panel 100, the snap fastener 270 is inserted into the socket 130 and will not be exposed. Therefore, this setting can at least hide part of the gate of the wiring cover 200, which to a certain extent ensures the flatness of the air conditioner cabinet and improves the aesthetics of the air conditioner cabinet.

[0050] In addition to the insertion and engagement of the snap fastener 270 and the socket 130, this embodiment also uses a threaded connector to fix the wiring cover 200 to the rear panel 100. This arrangement improves the reliability of the connection between the wiring cover 200 and the rear panel 100 and prevents the wiring cover 200 from falling off the rear panel 100.

[0051] Please continue to refer to Figure 1 and Figure 4 In this embodiment, the buckle 270 is disposed on the lower edge 250 of the wiring cover plate 200, and the gates of the wiring cover plate 200 are also distributed on its upper edge 260, left edge 230 and right edge 240.

[0052] By providing gates at the upper edge 260, lower edge 250, left edge 230 and right edge 240 of the wiring cover plate 200, the distribution range of gates in the wiring cover plate 200 can be increased, which is beneficial to the molding of the wiring cover plate 200.

[0053] In addition, this embodiment also provides an air conditioning unit, including the aforementioned rear panel assembly.

[0054] By incorporating the aforementioned rear panel assembly into the air conditioning unit, the air conditioning unit thus possesses all the advantages of the aforementioned rear panel assembly, which will not be elaborated upon here.
