[0033] The embodiment of the utility model provides a casing of a heat pump unit and a heat pump unit, which can quickly and conveniently install and remove the side panel, which is conducive to improving the work efficiency of installing and removing the side panel.

[0034] like Figure 1 to Figure 2As shown, the embodiment of the utility model provides a housing 100 of a heat pump unit, and the housing 100 has a receiving cavity 110 inside. The housing 100 includes: a column 120, a top plate 130 and a side panel 140, the column 120 and the top plate 130 are vertically connected to each other, the top plate 130 is located at the top of the receiving cavity 110, and the column 120 is located on opposite sides of the top plate 130, as shown in FIG. Figure 3 As shown, the top of the side panel 140 includes a pre-installed portion 141, such as Figures 4 to 6 As shown, there is a pre-installation space S1 between the column 120 and the top plate 130, the side panel 140 is located on the front side of the accommodating cavity 110, the side panel 140 can rotate along the top edge of the side panel 140, and the pre-installation portion 141 can extend into the pre-installation space S1, so that the side panel 140 can be detachably connected to the column 120.

[0035] The technical solution of the utility model is to set a pre-installation space S1 between the column 120 and the top plate 130, and set a pre-installation part 141 on the top of the side panel 140. The side panel 140 can rotate along the top edge of the side panel 140, and the pre-installation part 141 can extend into the pre-installation space S1, so that the side panel 140 can be detachably connected to the column 120, and the side panel 140 can be quickly and conveniently installed and removed, which is conducive to improving the work efficiency of installing and removing the side panel 140. It should be noted that the side panel 140 in the technical solution of the utility model can be installed on any side of the casing 100 of the heat pump unit.

[0036] like Figures 4 to 6 As shown, the pillar 120 is recessed on one side of the accommodating cavity 110 to provide a first bent portion 121 , and the pre-installation space S1 is located between the first bent portion 121 and the edge of the top plate 130 .

[0037] like Figure 3 As shown, the side panel 140 further includes a second bent portion 142, and the second bent portion 142 is disposed on the side of the side panel 140 facing the accommodating cavity 110. Figures 4 to 6 As shown, the second bending portion 142 can be connected with the first bending portion 121. The technical solution of the utility model further enhances the strength and rigidity of the side panel 140 structure by providing the second bending portion 142 on the side panel 140, which is beneficial to enhance the stability and mechanical strength of the overall structure of the housing 100 and avoid the housing 100 from shaking and being unstable.

[0038] like Figure 1As shown, the housing 100 further includes a bottom plate 150, which is located at the bottom of the accommodating cavity 110, and is arranged parallel to the top plate 130 and vertically connected to the column 120, and the side panel 140 is detachably connected to the bottom plate 150. Preferably, in one embodiment, the top plate 130 and the bottom plate 150 can be connected to opposite ends of the column 120 by connecting bolts, so that the top plate 130 and the bottom plate 150 can be limited to the column 120.

[0039] like Figure 2 As shown, the side of the bottom plate 150 facing the accommodating cavity 110 includes a connecting groove 151, as shown in FIG. Figure 3 As shown, the bottom of the side panel 140 includes a connecting portion 143 , and the connecting portion 143 and the connecting groove 151 can be connected to or separated from each other.

[0040] like Figures 4 to 6 As shown, the top plate 130 has a limiting portion 131, which is protrudingly arranged at the edge of the top plate 130. When the connecting portion 143 and the connecting groove 151 are connected to each other, the limiting portion 131 abuts against the pre-installing portion 141. The technical solution of the utility model is to set the limiting portion 131 on the top plate 130. After the side panel 140 is installed, the pre-installing portion 141 on the top of the side panel 140 can be embedded in the top plate 130, and the limiting portion 131 abuts against the pre-installing portion 141. The side panel 140 can not only provide a relatively stable side support for the top plate 130, but also effectively prevent the middle part of the side of the top plate 130 from being concave. At the same time, the limiting portion 131 limits the side panel 140, which is conducive to avoiding the side panel 140 from swinging, vibrating or making abnormal sounds, thereby enhancing the stability and mechanical strength of the overall structure of the heat pump unit casing 100 and avoiding the casing 100 from shaking and being unstable.

[0041] like Figures 2 to 3As shown, the first bending portion 121 has a plurality of first connection holes 1211, and the second bending portion 142 has a plurality of second connection holes 1421 arranged one-to-one with the first connection holes 1211. The first connection holes 1211 and the second connection holes 1421 can be connected to each other so that the side panel 140 can be limited to the column 120. After the connection portion 143 at the bottom of the side panel 140 is docked and installed with the connection groove 151 of the bottom plate 150, it is convenient to accurately align the first connection holes 1211 on both sides of the side panel 140 with the second connection holes 1421 of the column 120, without applying additional stabilizing force to the side panel 140. Preferably, the side panel 140 and the column 120 can be fixed by connecting screws. The fixing with connecting screws makes the side panel 140 more closely fit the column 120, and can also effectively prevent abnormal noise caused by the difference in vibration amplitude between the side panel 140 and the column 120, thereby ensuring the stable operation of the machine and extending its service life. At the same time, the side panel 140 is butted against the connection groove 151 of the bottom plate 150 through the bottom connection portion 143 , which also provides a solid support for the middle of the side panel 140 , effectively avoiding the risk of the side panel 140 being dented due to collision.

[0042] like Figure 3 As shown, the side panel 140 further includes a handle 144 and a handle mounting portion 145 , and the handle 144 is detachably disposed on the handle mounting portion 145 .

[0043] like Figure 3 As shown, the side panel 140 further includes a reinforcing rib 146, which is located on a side of the side panel 140 away from the accommodating cavity 110. The technical solution of the utility model further enhances the strength and rigidity of the structure of the side panel 140 by arranging the reinforcing rib 146 on the side panel 140, which is beneficial to enhance the stability and mechanical strength of the overall structure of the housing 100 and avoid the housing 100 from shaking and being unstable.

[0044] Next, the steps for installing the side panel 140 on either side of the heat pump unit are described.

[0045] First, the pillars 120, the top plate 130, and the bottom plate 150 are connected as follows: Figure 2 The three parts can be fixedly connected by connecting bolts. Next, the handle 144 is installed on the handle installation part 145 of the side panel 140 to facilitate holding the side panel 140 for subsequent installation. Figures 4 to 6As shown, hold the handle 144 and insert the pre-installation portion 141 on the top of the side panel 140 into the pre-installation space S1 between the column 120 and the top plate 130. Subsequently, rotate the side panel 140 along the top edge of the side panel 140, use the edge as the rotation axis, rotate clockwise and move upward at the same time until the side panel 140 is flush with the column 120. Next, lower the side panel 140 to ensure that the connection portion 143 at the bottom of the side panel 140 is accurately aligned with the connection groove 151 of the bottom plate 150, and install it in place. Finally, connect the first connection hole 1211 of the side panel 140 and the second connection hole 1421 of the column 120 by connecting screws to fix the side panel 140 to the column 120, thereby completing the entire assembly process. Preferably, in one embodiment, the side panel 140 is a single sheet metal structure, and the structural strength and rigidity of the side panel 140 are increased by providing the second bending portion 142, the reinforcing rib 146, etc. on the side panel 140. By installing the side panel 140 with the column 120, the top plate 130, and the bottom plate 150, not only the overall stability of the heat pump unit is improved, but also the individual strength performance of each component is further strengthened. Preferably, the column 120 and the side panel 140 are fastened by connecting screws, which not only provides mutual tensile support for the side panel 140 and the column 120, but also provides better stability for the heat pump unit in the scenario where the heat pump unit has large vibration and high strength requirements during operation. In addition, considering that the heat pump unit is usually in a non-operating or lightly operating state during maintenance, even if the side panel 140 is removed, there is no obvious effect on the overall strength of the heat pump unit. The disassembly step of the side panel 140 is a reverse operation of the above-mentioned assembly process. For a heat pump unit with a high height, it is difficult to disassemble and install the top plate 130, and a ladder or a professional space tool is required to assist the operation. The method of installing and disassembling the side panel 140 in the technical solution of the utility model can complete the disassembly and installation of the side panel 140 without disassembling the top plate 130.

[0046] The present invention also provides a heat pump unit, which includes a housing 100 of the heat pump unit according to any of the above embodiments of the present invention and a heat exchanger. Figure 2 As shown, the housing 100 has a receiving chamber 110 inside, and the heat exchanger is located in the receiving chamber 110. Figure 1 to Figure 2 As shown, the housing 100 includes: a column 120, a top plate 130 and a side panel 140, the column 120 and the top plate 130 are vertically connected to each other, the top plate 130 is located at the top of the accommodating cavity 110, and the column 120 is located on opposite sides of the top plate 130, as shown in FIG. Figure 3 As shown, the top of the side panel 140 includes a pre-installed portion 141, such as Figures 4 to 6As shown, there is a pre-installation space S1 between the column 120 and the top plate 130, the side panel 140 is located on the front side of the accommodating cavity 110, the side panel 140 can rotate along the top edge of the side panel 140, and the pre-installation portion 141 can extend into the pre-installation space S1, so that the side panel 140 can be detachably connected to the column 120.

[0047] The heat pump unit in the technical solution of the utility model includes a housing 100, and the housing 100 includes a column 120, a top plate 130, and a side panel 140. By setting a pre-installation space S1 between the column 120 and the top plate 130, and setting a pre-installation portion 141 on the top of the side panel 140, the side panel 140 can rotate along the top edge of the side panel 140, and the pre-installation portion 141 can extend into the pre-installation space S1, so that the side panel 140 can be detachably connected to the column 120, and the side panel 140 can be quickly and conveniently installed and removed, which is conducive to improving the work efficiency of installing and removing the side panel 140 in the heat pump unit. It should be noted that the side panel 140 in the technical solution of the utility model can be installed on any side of the heat pump unit.
