[0042] The chassis 10 of the air conditioning cabinet can be used in an indoor unit or an outdoor unit.

[0043] According to the chassis 10 of the air-conditioning cabinet of the utility model, a first pipe hole 114 is set on both sides of the first direction X of the chassis 10, and a second pipe hole 115 is set on both sides of the second direction Y of the chassis 10. The pipeline inside the air-conditioning cabinet can be introduced into the accommodating space of the chassis 10 from the opening 1131 at the top of the chassis 10, and led out from the accommodating space to the outside of the chassis 10 through the first pipe hole 114 and / or the second pipe hole 115, so that the pipeline can be led out from any direction around the chassis 10 to improve the flexibility of pipeline installation.

[0044] In some embodiments of the present invention, please continue to refer to Figure 1 , two forklift holes 116 spaced apart along the second direction Y are formed on one side of the body 11 along the first direction X, and another two forklift holes 116 spaced apart along the second direction Y are formed on the other side of the body 11 along the first direction X, and the two forklift holes 116 and the other two forklift holes 116 are both connected to the accommodation space, and their projections along the first direction X at least partially overlap. In other embodiments, two forklift holes 116 spaced apart along the first direction X are formed on one side of the body 11 along the second direction Y, and another two forklift holes 116 spaced apart along the first direction X are formed on the other side of the body 11 along the second direction Y, and the two forklift holes 116 and the other two forklift holes 116 are both connected to the accommodation space, and their projections along the second direction Y at least partially overlap.

[0045] Optionally, the forklift hole 116 may be a rectangular hole.

[0046] The distance between the two forklift holes 116 can be set according to the distance between forks of forklifts of different specifications.

[0047] The forklift hole 116 is provided to facilitate a forklift to lift the air-conditioning cabinet with the chassis 10 , so as to facilitate the transportation of the air-conditioning cabinet.

[0048] In some embodiments of the present invention, please continue to refer to Figure 2 The chassis 10 of the air conditioning cabinet further includes an annular reinforcement structure 117 , which is embedded in the forklift hole 116 , and the outer peripheral surface of the annular reinforcement structure 117 is connected to the edge of the forklift hole 116 .

[0049] Specifically, two forklift holes 116 are formed at one end of the body 11 along the first direction X, the two forklift holes 116 penetrate the other end of the body 11 along the first direction X, and the two forklift holes 116 are spaced apart along the second direction Y, and an annular reinforcement structure 117 is provided in each forklift hole 116, and the outer peripheral surface of the annular reinforcement structure 117 is connected to the edge of the forklift hole 116. In other embodiments, two forklift holes 116 are formed at one end of the body 11 along the second direction Y, the two forklift holes 116 penetrate the other end of the body 11 along the second direction Y, and the two forklift holes 116 are spaced apart along the first direction X, and an annular reinforcement structure 117 is provided in each forklift hole 116, and the outer peripheral surface of the annular reinforcement structure 117 is connected to the edge of the forklift hole 116.

[0050] Optionally, the outer peripheral surface of the annular reinforcement structure 117 is formed with a step, and the annular reinforcement structure 117 is plugged into the forklift hole 116 and can be connected to the body 11 by welding. The thickness of the annular reinforcement structure 117 along the depth direction of the forklift hole 116 can be greater than the thickness of the side wall of the body 11.

[0051] The provision of the annular reinforcement structure 117 can improve the rigidity of the chassis 10 at the forklift hole 116 , thereby reducing the probability of the chassis 10 being damaged due to excessive deformation of the forklift hole 116 caused by insufficient strength during the insertion process.

[0052] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 A first positioning structure 118 is formed on the top of the main body 11, and the first positioning structure 118 is used to limit the position of the water receiving box 20 of the air conditioning cabinet along the first direction X and the second direction Y.

[0053] Exemplarily, two first limit blocks spaced apart along the first direction X and two second limit blocks spaced apart along the second direction Y are provided on the top of the chassis 10. When the water receiving box 20 is placed on the inner chassis 10 of the chassis 10, the two first limit blocks abut against the two side walls of the water receiving box 20 along the first direction X, and the two second limit blocks abut against the two side walls of the water receiving box 20 along the second direction Y, so as to limit the movement of the water receiving box 20 along the first direction X and the second direction Y.

[0054] It can be understood that the water receiving box 20 is used to receive the condensed water generated by the evaporator when the air conditioner cabinet is working, and the water receiving box 20 is usually located. Optionally, the water receiving box 20 can be generally a square structure, and a water receiving port is provided on the top.

[0055] The setting of the first positioning structure 118 can ensure that the water receiving box 20 does not move inside the air-conditioning cabinet when the air-conditioning cabinet is working or moving, so that the relative position of the water receiving box 20 and the evaporator remains unchanged, so that the evaporator can receive more condensed water when working.

[0056] In some embodiments of the present invention, the first positioning structure 118 includes any one or more combinations of positioning holes, grooves, and protrusions.

[0057] For example, Figure 2 As shown, the first positioning structure 118 is a positioning hole, which is a circular hole, and the number of the positioning holes is at least two. Figure 4 and Figure 5 As shown, a protrusion is formed at the bottom of the water receiving box 20, and the number of the protrusions is the same as the number of the positioning holes, and each protrusion is located in each positioning hole. In other examples, the positioning holes can be replaced by grooves; or, the first positioning structure 118 is a protrusion, and the bottom of the water receiving box 20 is formed with a second positioning structure 21, and the second positioning structure 21 is a positioning hole, and the protrusion is plugged into the positioning hole. In another example, the first positioning structure 118 can be a special-shaped positioning hole, and the bottom of the water receiving box 20 is formed with a special-shaped positioning protrusion, and the special-shaped positioning protrusion serves as the second positioning structure 21. The profile of the cross section of the special-shaped positioning protrusion can be the same as the profile of the cross section of the special-shaped positioning hole, and the special-shaped positioning protrusion and the special-shaped positioning hole are plugged into each other to limit the movement of the water receiving box 20 along the first direction X and the second direction Y. For example, the special-shaped positioning hole can be a hexagonal positioning hole, and the special-shaped positioning protrusion can be a hexagonal protrusion, and the hexagonal positioning hole is plugged into the hexagonal protrusion. The number of the special-shaped positioning holes may be one or more, and the number of the special-shaped positioning protrusions may be the same as the number of the special-shaped positioning holes.

[0058] Therefore, the positioning holes, grooves and protrusions can all realize the positioning of the water receiving box 20 of the air-conditioning cabinet, and the structure is simple and convenient for processing and manufacturing.

[0059] In some embodiments of the present invention, please continue to refer to Figure 2 There are multiple first positioning structures 118, and the multiple first positioning structures 118 are arranged at intervals.

[0060] Compared with the case where the number of the first positioning structure 118 is one, the positioning of the water receiving box 20 can be made more reliable, so that the water receiving box 20 is less likely to be offset under the action of external force after being positioned.

[0061] In some embodiments of the present invention, please continue to refer to Figure 2 The main body 11 has connection structures 119 formed on both sides along the first direction X, and / or the main body 11 has connection structures 119 formed on both sides along the second direction Y.

[0062] During use, the chassis 10 needs to be connected to the side panel 30 of the air conditioning cabinet. The connection structure 119 is provided to facilitate the installation of the side panel 30 and the chassis 10 .

[0063] In some embodiments of the present invention, the connection structure 119 includes one or more combinations of mounting holes and slots.

[0064] Optionally, the connection structure 119 may be a mounting hole, and the number of the mounting holes may be one or more.

[0065] For example, Figure 2 and Figure 6 As shown, the main body 11 is provided with mounting holes at both ends along the first direction X, and the number of mounting holes at each end is multiple. Figure 2 The mounting holes in the embodiment are circular holes. In other examples, the mounting holes may also be long slot holes. The side panel 30 of the air-conditioning cabinet is provided with a plurality of bolt holes. The long slot holes are provided with a plurality of bolts. One end of each bolt passes through the bolt hole, and the side panel 30 is fixed to the chassis 10 by a nut. In other examples, the number of long slot holes at each end of the main body 11 along the first direction X is one, and each long slot hole is arranged opposite to each bolt hole and fixed by bolt connection. In other examples, the bolt holes may be replaced with threaded holes, the bolts may be replaced with screws, the long slot holes may be replaced with circular holes, and the number of circular holes is the same as the number of threaded holes. In other examples, on the basis of the above-mentioned bolt or screw connection, a hook may be provided on the surface of the side panel 30 of the air-conditioning cabinet. The hook is arranged in the slot, which may be used as the initial positioning of the side panel 30 and the chassis 10 to facilitate the connection of the bolts or screws.

[0066] Thus, the connection and disassembly of the side panel 30 and the chassis 10 of the air-conditioning cabinet can be facilitated.

[0067] According to an embodiment of the present utility model, an air conditioning cabinet is proposed, comprising the chassis 10 of the air conditioning cabinet of the above embodiment.

[0068] Since the above-mentioned air-conditioning cabinet includes all the technical features of the chassis 10 of the air-conditioning cabinet in the above-mentioned embodiment, the effects are the same as those described above and will not be repeated here.

[0069] In some embodiments of the present invention, please continue to refer to Figure 5 The air conditioning cabinet further includes a water receiving box 20, which is disposed on the top of the main body 11 and is plugged into and matched with the main body 11 to limit movement of the water receiving box 20 along the first direction X and the second direction Y.

[0070] Optionally, a protrusion is formed at the bottom of the water receiving box 20, and a positioning hole is formed at the top of the chassis 10. The protrusion is plugged into the positioning hole. The number of protrusions can be multiple, and the number of positioning holes is the same as the number of protrusions. The plug-in cooperation between the water receiving box 20 and the chassis 10 can be the same as the method listed in the chassis 10 of the above-mentioned air conditioning cabinet, and will not be repeated in detail here.

[0071] In some embodiments of the utility model, the air conditioning cabinet also includes a heat exchanger (not shown in the figure) and a delivery pipeline (not shown in the figure), the heat exchanger is located above the water receiving box 20, the delivery pipeline is connected to the heat exchanger, and the end of the delivery pipeline is led out from the first pipe hole 114 and / or the second pipe hole 115 to the outside of the chassis 10.

[0072] In some embodiments of the present invention, please continue to refer to Figure 6 The air conditioner cabinet further includes an air inlet grille 40 and an air outlet grille 50, which are respectively connected to the two side panels 30, and the air inlet grille 40 is located above the air outlet grille 50, and the air inlet grille 40 and the air outlet grille 50 are spaced apart.
