[0008] The rear panel has a maintenance opening;
[0009] The tube outlet plate is slidably mounted on the rear enclosure and covers the maintenance port; the lower edge of the tube outlet plate is provided with a tube outlet for leading out the output tube.
[0010] In practical applications, the air conditioner cabinet unit provided by this utility model allows the outlet plate to slide up and down relative to the rear panel, ensuring ideal engagement between the outlet and output pipes of different diameters, thereby minimizing the gap between the output pipe and the outlet hole wall. Therefore, the air conditioner cabinet unit provided by this utility model can effectively control the gap between the output pipe and the outlet hole wall without increasing the number of parts or production costs.
[0011] In an optional embodiment, the outer surface of the rear panel is recessed with a tube sheet groove, and the tube sheet is slidably disposed within the tube sheet groove. The vertical dimension of the tube sheet groove is larger than the vertical dimension of the tube sheet. The larger vertical dimension of the tube sheet groove provides clearance for the vertical sliding of the tube sheet.
[0012] In an optional embodiment, the bottom wall of the tube sheet groove has two sliding surfaces, which are located on opposite sides of the maintenance port in the vertical direction.
[0013] The two sliding surfaces on the bottom wall of the tube sheet groove correspond to the extreme positions of the maintenance port's vertical sliding, preventing the bottom and top of the maintenance port from being exposed.
[0014] In an optional embodiment, the sliding surface above the outlet plate is provided with an upper stop that extends into the maintenance port, the upper stop being located at the middle position of the top of the maintenance port; and / or,
[0015] The sliding surface located below the outlet plate is provided with a lower stop that extends into the maintenance port, and the lower stop is located at the middle position of the bottom of the maintenance port.
[0016] The upper and lower stops provide reliable support to the tube sheet from the middle of the top and bottom, respectively, further enhancing the overall structural stability.
[0017] In an optional embodiment, the bottom wall of the tube sheet groove is further provided with a mounting plate, and the tube sheet and the mounting plate are slidably engaged.
[0018] The tube sheet and the mounting plate can slide together, allowing them to slide up and down relative to the rear enclosure plate when subjected to force.
[0019] In an optional embodiment, the mounting plate is provided with fasteners, and the outlet plate is provided with a waist-shaped hole extending in the vertical direction, through which the fasteners pass.
[0020] The fastener passes through the waist-shaped part and slidably engages with the waist-shaped hole, enabling the fastener to slide on the rear panel and guiding the fastener's up and down movement.
[0021] In an optional embodiment, the mounting plate has a protruding rib extending in the vertical direction on the side near the outer surface of the rear panel.
[0022] The raised ribs on the mounting plate serve two purposes: firstly, to increase the strength of the mounting plate, and secondly, to prevent large-area contact between the tube sheet and the mounting plate, thus ensuring smooth sliding of the tube sheet.
[0023] In an optional embodiment, the number of mounting plates is two, and the two mounting plates are respectively located on opposite sides of the maintenance port in the horizontal direction.
[0024] The two mounting plates are located on opposite sides of the maintenance port in the horizontal direction, providing stable support for the tube sheet.
[0025] In an optional embodiment, the lower edge of the tube sheet is further provided with a downwardly protruding positioning part, which is inserted into the rear panel.
[0026] The tube sheet is positioned and connected to the rear panel to limit the bottom of the tube sheet in the horizontal direction, preventing the tube sheet from shaking significantly or the bottom from tilting up.
[0027] In an optional embodiment, the outlet plate is provided with a breakable cover plate that seals the outlet port.
[0028] Before installing the air conditioner unit, break off the cover to keep the outlet pipe sealed, preventing external substances from entering the unit through the outlet. Breaking off the cover will expose the outlet pipe, allowing for proper installation of the air conditioner unit. Attached Figure Description

Detailed Implementation
[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0037] Please refer to the following: Figure 1 , Figure 2 and Figure 3 , Figure 1 The diagram shown is a structural schematic of the air conditioner unit 100 provided in this embodiment. Figure 2 As shown Figure 1 Enlarged diagram of region A in the middle. Figure 3 As shown Figure 1 A schematic diagram of the decomposition of region A in the middle.
[0038] The air conditioner unit 100 provided in this embodiment includes a rear panel 110 and a pipe outlet plate 120. It also includes conventional structures such as the unit body, compressor, and air duct assembly, which will not be described further in this embodiment. A maintenance port 111 is provided on the rear panel 110. The pipe outlet plate 120 is slidably mounted on the rear panel 110 and covers the maintenance port 111. A pipe outlet 121 is provided on the lower edge of the pipe outlet plate 120 for leading out the compressor's output pipe.
[0039] It is understandable that the outlet 121 is located at the lower edge of the outlet plate 120, meaning the opening of the outlet 121 faces downwards. In practical applications, the compressor's output pipe passes through the outlet 121. The outlet 121 can slide vertically relative to the rear panel 110 under the action of the outlet plate 120, thus engaging with the outer wall of the output pipe. This effectively controls the gap between the output pipe and the wall of the outlet 121, preventing external insects and other substances from entering the air conditioner unit 100 and causing malfunctions.
[0040] In this embodiment, the outer surface of the rear panel 110 is recessed with a tube plate groove 112 for installing the tube plate 120. The tube plate 120 is slidably disposed in the tube plate groove 112. The vertical dimension of the tube plate groove 112 is larger than the vertical dimension of the tube plate 120.
[0041] The tube sheet groove 112 provides clearance for the vertical sliding of the tube sheet 120. In practical applications, under the influence of gravity, the tube sheet 120 is located at the bottom of the tube sheet groove 112. Applying a force to the tube sheet 120 allows it to slide upwards along the tube sheet groove 112 until it reaches the top of the groove. When the force is removed, the tube sheet 120 slides down to the bottom of the tube sheet groove 112 under gravity.
[0042] During the actual installation of the air conditioner unit 100, when leading the output pipe out of the maintenance port 111, the tube plate 120 can be slid upward first to maximize the distance between the lower edge of the tube plate 120 and the bottom of the tube plate groove 112, thus providing sufficient operating space for leading out the output pipe.
[0043] After the output tube leads out of the maintenance port 111, align the output tube with the outlet 121 and lower the tube sheet 120 until the outlet 121 is engaged with the outer wall of the output tube. With the outlet 121 engaged with the output tube, the outer wall of the output tube contacts the side wall of the outlet 121 away from the lower edge of the tube sheet 120.
[0044] It is understandable that regardless of whether the tube sheet 120 is at the bottom or top of the tube sheet groove 112, the tube sheet 120 always keeps the maintenance port 111 covered, and only the tube outlet 121 is connected to the maintenance port 111, so that the compressor's output pipe can be led out through the maintenance port 111 and the tube outlet 121 and connected to the outdoor unit of the air conditioner.
[0045] It should be noted that, in another embodiment, the tube sheet groove 112 can be omitted, and the maintenance port 111 can be directly opened on the outer surface of the rear panel 110. In this case, the tube sheet 120 slides with the rear panel 110 and can slide directly up and down on the outer side of the rear panel 110.
[0046] In order to allow for the sliding stroke of the tube sheet 120, in this embodiment, the bottom wall of the tube sheet groove 112 has two sliding surfaces 113, which are located on opposite sides of the maintenance port 111 in the vertical direction.
[0047] In practical applications, when the tube sheet 120 slides to the bottom of the tube sheet groove 112, the tube sheet 120 can completely cover the sliding surface 113 below the maintenance port 111, while the sliding surface 113 above the maintenance port 111 is at least partially exposed. When the tube sheet 120 slides upward to the top of the tube sheet groove 112, the tube sheet 120 can completely cover the sliding surface 113 above the maintenance port 111, while the sliding surface 113 below the maintenance port 111 is at least partially exposed.
[0048] In order to reliably support the tube sheet 120 and ensure the stability of the overall structure, in this embodiment, the sliding surface 113 above the tube sheet 120 is provided with an upper stop 114 that extends into the maintenance port 111. The upper stop 114 is located in the middle of the top of the maintenance port 111.
[0049] Furthermore, the sliding surface 113 located below the outlet plate 120 is provided with a lower stop 115 that extends into the maintenance port 111, and the lower stop 115 is located in the middle of the bottom of the maintenance port 111.
[0050] Understandably, the upper stop 114, the lower stop 115, and the two sliding surfaces 113 all serve to support the tube sheet 120 at its front, ensuring that the tube sheet 120 can slide smoothly up and down within the tube sheet groove 112 and preventing significant wobbling during the sliding process. The two sliding surfaces 113 mainly support the tube sheet 120 from its upper and lower ends, while the upper stop 114 and the lower stop 115 extend into the maintenance port 111 to support the tube sheet 120.
[0051] A mating hole can be provided through the upper stop 114 and the lower stop 115. A mating structure can be provided on the inner surface of the tube outlet plate 120 and inserted into the mating hole. During the up-and-down sliding of the tube outlet plate 120 relative to the rear cover plate 110, the mating structure slides up and down within the mating hole. Through the slidable engagement of the mating structure and the mating hole, the sliding of the tube outlet plate 120 can be guided, and the horizontal movement of the tube outlet plate 120 relative to the rear cover plate 110 can be prevented, thus improving the smoothness of the sliding process.
[0052] In this embodiment, for the installation of the tube sheet 120, a mounting plate 116 is also provided on the bottom wall of the tube sheet groove 112, and the tube sheet 120 and the mounting plate 116 are slidably engaged. Specifically, the mounting plate 116 is provided with fasteners, and the tube sheet 120 is provided with a waist-shaped hole 122 extending in the vertical direction, through which the fasteners pass.
[0053] In practical applications, the fastener can be a screw, and the mounting plate 116 can be provided with a screw hole corresponding to the screw. During assembly, the tube sheet 120 is inserted into the tube sheet groove 112, so that the screw hole of the mounting plate 116 aligns with the oblong hole 122 on the tube sheet 120. Then, the screw is passed through the oblong hole 122 from the outside of the tube sheet 120 and screwed into the screw hole of the mounting plate 116, completing the installation of the tube sheet 120 on the mounting plate 116.
[0054] In another embodiment, the fastener can be selected according to the actual application conditions. The fastener slides with the oblong hole 122 on one hand, and stops the tube sheet 120 on the rear side of the tube sheet 120 on the other, preventing the tube sheet 120 from dislodging backward from the tube sheet groove 112. During the up-and-down sliding of the tube sheet 120 within the tube sheet groove 112, the fastener slides up and down within the oblong hole 122, guiding the sliding of the tube sheet 120 and ensuring a smooth and stable sliding process.
[0055] To enhance the structural strength of the mounting plate 116, in this embodiment, a vertically extending rib 117 is provided on the side of the mounting plate 116 near the outer surface of the rear panel 110. In fact, the rib 117 on the mounting plate 116 not only improves the strength of the mounting plate 116, but also prevents large-area contact between the tube sheet 120 and the mounting plate 116, further improving the smoothness of the tube sheet 120's vertical sliding process.
[0056] Preferably, in this embodiment, there are two mounting plates 116, which are located on opposite sides of the maintenance port 111 in the horizontal direction. The upper stop 114 and the lower stop 115 are both located between the two mounting plates 116. It can be understood that the two mounting plates 116 mainly support the outlet plate 120 from the horizontal sides of the outlet plate 120.
[0057] Please refer to the following: Figure 4 and Figure 5 , Figure 4 The diagram shown is a cross-sectional view of the air conditioner unit 100 provided in this embodiment. Figure 5 As shown Figure 4 Enlarged schematic diagram of region B in the middle.
[0058] In order to ensure the stable and reliable assembly structure of the tube sheet 120 and the rear cover plate 110 and to prevent the tube sheet 120 from coming out of the tube sheet groove 112, in this embodiment, the lower edge of the tube sheet 120 is also provided with a downwardly protruding positioning part 123, which is inserted into the rear cover plate 110.
[0059] Understandably, the rear panel 110 has a recessed insertion hole corresponding to the positioning part 123. When the tube plate 120 slides downward to the bottom of the tube plate groove 112, the positioning part 123 is fully inserted into the corresponding insertion hole. When the tube plate 120 slides upward, the positioning part 123 slides upward along the insertion hole. When the tube plate 120 slides to the top of the tube plate groove 112, the positioning part 123 remains in the insertion state with the insertion hole.
[0060] To ensure the airtightness of the air conditioner unit 100 before installation, in this embodiment, the outlet plate 120 is provided with a breakable cover plate 124 to cover the outlet port 121. It is understood that the periphery of the breakable cover plate 124 is provided with a tear line formed by spaced through holes. When installing the air conditioner unit 100, the breakable cover plate 124 is broken along the tear line to expose the outlet port 121.
[0061] As can be seen, the air conditioner cabinet unit 100 provided in this embodiment achieves the engagement of the outlet 121 with the output pipe by slidably mounting the outlet plate 120 on the rear panel 110, resulting in a very small gap between the two. Therefore, the air conditioner cabinet unit 100 provided in this embodiment can effectively control the gap between the output pipe and the wall of the outlet 121 without increasing the number of parts or production costs.
[0062] While the present invention has been disclosed above, it is not limited thereto. 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.
