[0035] Figure 1 The heat pump host of an embodiment of the utility model is shown, which may include a housing 1 and a heat pump system arranged in the housing 1. Figure 2 , Figure 5 and Figure 6 The housing 1 includes a cover plate 10, a first front side plate 20 and a grille plate 40. The cover plate 10 is disposed at the top of the first front side plate 20 and the grille plate 40. The grille plate 40 is overlapped and disposed on the outer side of the first front side plate 20 to cover the vents on the first front side plate 20 to prevent larger foreign objects from entering. The three are detachably connected to simplify the disassembly and assembly process of the heat pump host and facilitate the maintenance of the heat pump host.

[0036] Specifically, the cover plate 10 includes a top wall 11 and a side wall 12, the side wall 12 is arranged around the top wall 11, and the top end of the side wall 12 is connected to the top wall 11. The first front side plate 20 is overlapped with the grid plate 40. At least a portion of the lower end of the side wall 12 is inserted between the grid plate 40 and the first front side plate 20.

[0037] The present application realizes the assembly between the cover plate 10, the grid plate 40 and the first front side plate 20 by inserting at least part of the side end of the side wall 12 of the cover plate 10 between the grid plate 40 and the first front side plate 20 through plug-in assembly, thereby reducing the use of screws and other connecting parts in the shell 1 and simplifying the assembly process. When assembling the cover plate 10, it is only necessary to insert its lower end between the grid plate 40 and the first front side plate 20, which is convenient and quick.

[0038] In this embodiment, the housing 1 is substantially in the shape of a cube, so that the top wall 11 of the cover plate 10, the first front side plate 20 and the grid plate 40 are all in a rectangular shape.

[0039] The shell 1 also includes a second front side plate 30, a bottom plate (not shown in the figure) and other side plates. The first front side plate 20, the cover plate 10 and the second front side plate 30 are detachably connected. The first front side plate 20 and the second front side plate 30 are roughly on the same plane, and together constitute the front side plate of the shell 1. The other side plates are detachably connected to the first front side plate 20 and the second front side plate 30, and together form the circumferential side plates of the shell 1. The cover plate 10 is arranged at the top end of the first front side plate 20, the second front side plate 30, the grid plate 40 and other side plates, and the bottom plate is detachably disassembled at the bottom end.

[0040] It should be understood that the other side panels may be a plurality of detachably connected side panels, or may be an integrally formed side panel, which is not specifically limited here.

[0041] In some other optional embodiments, the housing 1 may also be in other shapes such as columnar, hemispherical, irregular, etc. At this time, the first front side plate 20, the second front side plate 30, the grid plate 40 and the cover plate 10 may be correspondingly set to other shapes such as irregular shapes, three-dimensional arc plates, etc.

[0042] like Figure 2 As shown, in some embodiments, the side wall 12 includes a shielding portion 121, an extension portion 122, and a plug-in portion 123. The shielding portion 121 is arranged around the top wall 11, perpendicular to the top wall 11, and its top end is connected to the top wall 11, and it can shield connecting parts such as screws. The extension portion 122 is arranged in a plate shape, perpendicular to the shielding portion 121, and the outer end is connected to the bottom end of the shielding portion 121. The plug-in portion 123 is also arranged in a plate shape, perpendicular to the extension portion 122, and its top end is connected to the inner end of the extension portion 122.

[0043] When the cover plate 10 is assembled with the first front side plate 20 and the grille plate 40 , the extension portion 122 is interposed between the grille plate 40 and the first front side plate 20 .

[0044] It should be understood that, in this embodiment, the dimensions of the extension portion 122 and the plug portion 123 only correspond to the first front side plate 20 and the grid plate 40 . Therefore, only the shielding portion 121 is disposed around the top wall 11 in the circumferential direction.

[0045] Read also Figure 4 Furthermore, the top end of the grid plate 40 is close to the side of the first front side plate 20 (i.e., the inner side of the top end of the grid plate 40), and is recessed toward the side away from the first front side plate 20 (i.e., the outer side of the top end of the grid plate 30) to form a clearance groove 41, which is used to provide clearance for the plug-in portion 123 so that the plug-in portion 123 can be inserted between the grid plate 40 and the first front side plate 20.

[0046] In some other optional embodiments, the plug-in portion 123 can also be a plurality of spaced connection blocks, which are spaced and vertically arranged at the inner side end of the extension portion 122. Correspondingly, a plurality of clearance grooves 41 are formed at intervals on the grid plate 40, which correspond to the plurality of plug-in portions 123 one by one, so as to realize the insertion of the plug-in portions 123. In this case, the shape of the connection block is not limited, and only the clearance grooves 41 of the grid plate 40 need to correspond to it so as to realize the insertion. The number and spacing distance are also not limited.

[0047] In some embodiments, the width of the extension portion 122 is adapted to the thickness of the grid plate 40. The width and thickness are set so that after the housing 1 is assembled, the front end surface of the shielding portion 121 and the front end surface of the grid plate 40 are on the same plane to ensure the smoothness of the outer contour of the housing 1 and reduce damage such as bumps and wear.

[0048] At the same time, the shielding portion 121 can also serve as a shielding decoration, shielding the exposed screws and other connecting parts at the top of the first front side plate 20, further reducing the exposed screws and other connecting parts on the front end surface of the shell 1, and ensuring the flatness of the outer contour of the shell 1.

[0049] Furthermore, the height difference between the first front side plate 20 and the grid plate 40 is matched with the width of the shielding portion 121. When the housing 1 is assembled, the top of the grid plate 40 is in contact with the bottom of the shielding portion 121. At the same time, since the width of the extension portion 122 is matched with the thickness of the grid plate 40, the front side end surface of the housing 1 can be formed by splicing a plurality of plate-like structures to form a smooth entire plane.

[0050] In this embodiment, the height of the grid plate 40 and the width of the shielding portion 121 are equal to the height of the first front side plate 20, that is, equal to the height of the housing 1. That is, when the housing 1 is assembled, the top end of the first front side plate 20 contacts the lower wall surface of the top wall 11 of the cover plate 10.

[0051] In some other optional embodiments, the height of the first front side plate 20 can also be slightly less than the sum of the height of the grid plate 40 and the width of the shielding portion 121. Or it can be roughly equal to the height of the grid plate 40. It should be understood that the height setting of the first front side plate 20 only needs to ensure that after the housing 1 is assembled, the top end of the grid plate 40 is connected to the bottom end of the shielding portion 121, and the plug-in portion 123 can be inserted between it and the grid plate 40 to achieve the assembly of the three.

[0052] like Figure 7 As shown, in some implementations, the second front side plate 30 includes a first body 31 and at least one first connection structure 33. At least one first connection hole 124 is correspondingly formed on the cover plate 10, and the first connection structure 33 is disposed at the top of the first body 31 and detachably penetrated into the first connection hole 124.

[0053] The first connection structure 33 and the first connection hole 124 are provided so that during the assembly process of the second front side plate 30 and the cover plate 10, it is only necessary to push the second front side plate 30 upwards and insert the first connection structure 33 into the first connection hole 124. This further reduces the number of connection parts such as screws in the housing 1, and simplifies the assembly process.

[0054] Meanwhile, when the heat pump main unit needs to be repaired, after removing the screws between the second front side plate 30 and other side plates, the second front side plate 30 moves downward by its own gravity and can be automatically removed from the cover plate 10. That is, after removing the second front side plate 30, the components in the housing 1 can be repaired without removing the cover plate 10.

[0055] Read also Figure 5 and Figure 6 Specifically, in the present embodiment, the first main body 31 is in the shape of a rectangular plate. The first connecting structure 33 is in the shape of a plate. The second front side plate 30 also includes a first connecting portion 32, which is in the shape of a longitudinal plate, and its length is roughly adapted to the width of the first main body 31, and its width is relatively narrow. The first connecting portion 32 is perpendicular to the first main body 31, and one of its long sides (outer end edge) is connected to the top edge of the first main body 31. The first connecting structure 33 is in the shape of a sheet, connected to the other long side (inner end edge) of the first connecting portion 32, and connected to the first main body 31 through the first connecting portion 32. The first connecting structure 33 and the first connecting portion 32 are on the same plane. The first connecting hole 124 is formed at the connection between the extension portion 122 and the plug-in portion 123.

[0056] Furthermore, the width of the first connection portion 32 matches the width of the extension portion 122, so that after the first connection structure 33 is inserted into the first connection hole 124, the outer end surface of the first body 31, the outer end surface of the shielding portion 121, and the outer end surface of the grid plate 40 are all on the same horizontal plane, so as to further ensure the flatness of the outer contour of the housing 1.

[0057] During the assembly of the second front side plate 30 and the cover plate 10, the first connection structure 33 is gradually inserted into the first connection hole 124, and the plug-in portion 123 is gradually moved relatively to the bottom of the first connection portion 32 until the extension portion 122 overlaps and contacts the first connection portion 32. At this time, the shielding portion 121, the grid plate 40 and the first body 31 are all on the same plane, and the bottom end of the shielding portion 121 is connected to the top end of the grid plate 40 and the top end of the first body 31 respectively.

[0058] In this embodiment, the number of the first connection structures 33 is multiple, and they are arranged at intervals on the side of the first connection portion 32 away from the first body 31 to improve the firmness of the assembly between the second front side plate 30 and the cover plate 10. The cover plate 10 is provided with multiple first connection holes 124 correspondingly.

[0059] In some other optional embodiments, the second front side plate 30 may not be provided with the first connecting portion 32, and the first connecting structure 33 is directly provided at the top of the first body 31. By providing the first connecting hole 124 at the connection between the shielding portion 121 and the extending portion 122, the positional relationship between the cover plate 10, the first front side plate 20, the second front side plate 30 and the grid plate 40 can be coordinated while the two are connected.

[0060] For example Figure 5 and Figure 6 As shown, in some embodiments, the shell 1 further includes a connecting strip 50 , the first front side plate 20 and the second front side plate 30 are partially overlapped, and the first front side plate 20 and the second front side plate 30 are detachably connected via the connecting strip 50 .

[0061] Specifically, at least one second connection hole 21 is formed at the portion where the first front side plate 20 overlaps the second front side plate 30. The connection strip 50 is partially located between the first front side plate 20 and the second front side plate 30, and is formed with at least one third connection hole 5121. The third connection hole 5121 corresponds to the second connection hole 21.

[0062] Read also Figure 7 and Figure 8 The second front side plate 30 further includes at least one second connection structure 35. The second connection structure 35 is disposed at a portion where the first body 31 overlaps the first front side plate 20, and is detachably inserted into the second connection hole 21 and the third connection hole 5121.

[0063] By setting the second connection structure 35, the second connection hole 21 and the third connection hole 5121, the first front side plate 20, the second front side plate 30 and the connection strip 50 are detachably connected. During the assembly process, it is only necessary to insert the second connection structure 35 into the second connection hole 21 and the third connection hole 5121 to achieve the assembly of the three. The number of screws and other connecting parts provided on the shell 1 is further reduced, thereby shortening the disassembly and assembly time, so as to reduce the workload of the operators during the assembly, disassembly, and maintenance processes. Among them, the connection strip 50 can also realize the decorative function of the shell 1 and enhance the aesthetics of the heat pump host.

[0064] At the same time, since the first front side plate 20, the grid plate 40 and the cover plate 10 can be assembled by plugging, the second front side plate 30 and the cover plate 10 can be assembled by plugging the first connection structure 33 into the first connection hole 124. Therefore, the cover plate 10, the first front side plate 20, the second front side plate 30, the grid plate 40 and the connecting strip 50 can be assembled with each other by a detachable connection method such as plugging, so that the five are combined into a whole, and the firmness of the assembly of the housing 1 is improved.

[0065] Furthermore, if Figure 7 and Figure 8 As shown, in some embodiments, the second connection structure 35 is in an L-shaped sheet shape and is perpendicular to the first body 31. That is, the second connection structure 35 is vertically arranged on the first body 31. One end of the L-shaped short side is connected to the first body 31 and is perpendicular to the first body 31. The L-shaped long side extends upward from the other end of the L-shaped short side and is arranged parallel to the first body 31.

[0066] The L-shaped structure of the second connection structure 35 allows, during the assembly process, the second connection structure 35 only needs to be horizontally pushed into the second connection hole 21 and the third connection hole 5121, and then the second front side plate 30 is pushed upward as a whole, so that at least part of the L-shaped long side of the second connection structure 35 can be abutted against the first front side plate 20 and the connecting strip 50. At this time, the second connection structure 35 cannot horizontally escape from the second connection hole 21 and the third connection hole 5121. The second front side plate 30, the first front side plate 20 and the connecting strip 50 are assembled.

[0067] During the process of assembling the second front side plate 30, after the second connection structure 35 is horizontally inserted into the second connection hole 21 and the third connection hole 5121, when the second front side plate 30 needs to be pushed up, in addition to the L-shaped long side of the second connection structure 35 moving up to abut against the first front side plate 20, the first connection structure 33 will also be synchronously inserted into the first connection hole 124 during the pushing-up process. That is, the second front side plate 30 and the cover plate 10 are assembled synchronously, further reducing the assembly steps of the housing 1.

[0068] In this embodiment, the second front side panel 30 is also fixed with other side panels (not the first front side panel 20) by screws and other connecting parts. Therefore, during assembly, after the second front side panel 30 is pushed up and assembled with the first front side panel 20, the connecting strip 50, and the cover plate 10, it is necessary to install screws and other connecting parts to achieve assembly with other side panels. During disassembly, after the screws between the second front side panel 30 and the other side panels are removed, the second front side panel 30 will automatically slide downward due to its own gravity. After the second front side panel 30 slides down, its second connecting structure 35 is all at a height position corresponding to the second connecting hole 21 and the third connecting hole 5121, and the first connecting structure 33 is also completely out of the first connecting hole 124. At this time, the second front side panel 30 can be easily moved to complete the second connecting structure 35 from the second connecting hole 21 and the third connecting hole 5121.

[0069] In some other optional embodiments, the second connection structure 35 can also be configured as other shapes such as an L-shaped column.

[0070] Correspondingly, the second connection hole 21 includes a first hole portion 211 and a second hole portion 212 connected in the longitudinal direction (vertical direction). The first hole portion 211 and the second hole portion 212 are both arranged in a longitudinally long rectangular shape. The first hole portion 211 is located above the second hole portion 212. The width of the first hole portion 211 is adapted to the thickness of the second connection structure 35 and is smaller than the width of the second hole portion 212. The sum of the lengths of the first hole portion 211 and the second hole portion 212 should be greater than the length of the long side of the L-shape of the second connection structure 35.

[0071] The second connection hole 21 has different widths in the vertical direction, which can be matched with the L-shaped sheet structure of the second connection structure 35. After the first front side plate 20 and the second front side plate 30 are assembled, the L-shaped short side of the second connection structure 35 can be clamped in the first hole portion 211, thereby improving the firmness of the two after assembly.

[0072] It should be understood that, for the second connection structure 35 with other structures or other setting angles, the setting angles and sizes of the first hole portion 211 and the second hole portion 212 can be adaptively adjusted.

[0073] Since the connecting strip 50 is partially sandwiched between the first front side plate 20 and the second front side plate 30, the third connecting hole 5121 is located between the second front side plate 30 and the first front side plate 20 (the second connecting hole 21). During the assembly process, the second connecting structure 35 first passes through the third connecting hole 5121 and then passes through the second connecting hole 21. For ease of assembly, in this embodiment, the third connecting hole 5121 is arranged in a longitudinal rectangular shape. Figure 6 As shown, its width matches the width of the second hole portion 212 of the second connecting hole 21 , and its length is slightly greater than the sum of the lengths of the first hole portion 211 and the second hole portion 212 .

[0074] In some other optional embodiments, the width of the third connection hole 5121 may be slightly larger or smaller than the width of the second hole portion 212. Its shape may also be set to be the same as the second connection hole 21. It should be understood that the shape and size of the third connection hole 5121 and the second connection hole 21 may also be flexibly set, so that the second connection structure 35 can pass through.

[0075] Continue reading Figure 7 In some embodiments, the second front side plate 30 further includes a second connecting portion 34, which is arranged in a longitudinal plate shape. The height is adapted to the height of the first body 31, and the width is narrow. It is connected to the side of the first body 31 close to the first front side plate 20 and is perpendicular to the first body 31. The second connecting structure 35 is connected to the second connecting portion 34, and is arranged on the first body 31 through the second connecting portion 34, and the second connecting structure 35 and the second connecting portion 34 are on the same plane.

[0076] By providing the second connecting portion 34, the connection area between the plane where the second connecting structure 35 is located and the first main body 31 can be expanded, and the connection strength of the second connecting structure 35 can be strengthened, so as to avoid the second connecting structure 35 and the first main body 31 from breaking after the heat pump host is used for a long time or the shell 1 is disassembled and assembled many times.

[0077] In this embodiment, the width of the second connection portion 34 matches the width of the first connection portion 32. When the first front side plate 20, the second front side plate 30, the grid plate 40 and the cover plate 10 are assembled, the first connection portion 32 fits with the extension portion 122, and the second connection portion 34 fits with the side of the grid plate 40. Figure 3 At this time, the front end surface of the assembled second front side plate 30 can be flush with the front end surface of the grid plate 40 located at the front end of the first front side plate 20, ensuring the smoothness of the outer contour of the shell and reducing bump damage.

[0078] In this embodiment, the number of the second connection structures 35 is multiple, and they are evenly spaced and arranged on the side of the second connection portion 34 away from the first body 31, so as to improve the firmness of the assembly between the second front side plate 30 and the first front side plate 20 and the connection strip 50. Correspondingly, the number of the second connection holes 21 and the third connection holes 5121 is correspondingly set to multiple.

[0079] For example Figure 7 and Figure 8 As shown, in some embodiments, the connecting strip 50 includes a second body 51 and at least one third connecting structure 52, the third connecting hole 5121 is formed on the second body 51, and the third connecting structure 52 is disposed on the second body 51. The first front side plate 20 also includes at least one fourth connecting hole 22, and the third connecting structure 52 is detachably inserted into the fourth connecting hole 22, so that the connecting strip 50 and the first front side plate 20 are detachably connected. This improves the firmness of the assembly between the first front side plate 20, the second front side plate 30 and the connecting strip 50.

[0080] Specifically, the third connection structure 52 is in an L-shaped sheet shape. Its L-shaped short side is perpendicular to the second body 51, and one end is connected to the second body 51. Its L-shaped long side is connected to the other end of the L-shaped short side and extends downward. Its L-shaped long side is parallel to the second body 51.

[0081] The L-shaped sheet structure of the third connection structure 52 allows the third connection structure 52 to be horizontally moved into the fourth connection hole 22 during the assembly of the connection bar 50 and the first front side plate 20. The connection bar 50 is then moved downward so that the L-shaped long side of the third connection structure 52 is located outside the fourth connection hole 22 and abuts against the first front side plate 20, thereby achieving assembly of the two. The process is convenient and quick.

[0082] At the same time, since the third connection structure 52 is in an L-shaped sheet shape with the long side extending downward, and the second connection structure 35 is in an L-shaped sheet shape with the long side extending upward, when the first front side plate 20, the second front side plate 30 and the connection strip 50 are assembled, the force direction between the connection strip 50 and the first front side plate 20 and the force direction between the second front side plate 30 and the first front side plate 20 and the connection strip 50 are opposite, so the firmness of the assembly between the three can be further improved.

[0083] In some other optional embodiments, the third connection structure 52 may also be configured as an L-shaped column or other shapes.

[0084] Further, the fourth connection hole 22 includes a third hole portion 221 and a fourth hole portion 222 connected in the longitudinal direction (vertical direction), and the third hole portion 221 is located below the fourth hole portion 222. The width of the third hole portion 221 is adapted to the thickness of the third connection structure 52 and is smaller than the width of the fourth hole portion 222. The sum of the lengths of the third hole portion 221 and the fourth hole portion 222 should be greater than the length of the L-shaped long side of the third connection structure 52.

[0085] The fourth connection hole 22 has different widths in the vertical direction, which can be matched with the L-shaped sheet structure of the third connection structure 52. After the connection strip 50 and the first front side plate 20 are assembled, the L-shaped short side of the third connection structure 52 can be clamped in the third hole portion 221, thereby improving the firmness of the two after assembly.

[0086] It should be understood that, for the third connection structure 52 with other structures or other setting angles, the setting angles and sizes of the third hole portion 221 and the fourth hole portion 222 can be adaptively adjusted.

[0087] Specifically, if Fig. 9 As shown, in this embodiment, the second body 51 includes a first part 511 and a second part 512. The first part 511 and the second part 512 are both arranged in a longitudinal direction and have the same length. The horizontal cross-section of the first part 511 is in a concave shape, and the second part 512 is in a sheet shape. One side of the second part 512 is connected to one side of the first part 511, and the second part 512 is perpendicular to the wall surface where the concave side of the first part 511 is located. The third connecting hole 5121 is formed on the second part 512. The third connecting hole 5121 is formed on the second part 512. The third connecting structure 52 is arranged on the side end of the first part 511 away from the second part 512.

[0088] The structural arrangement of the second main body 51 enables, when the connecting strip 50 is assembled with the first front side panel 20 and the second front side panel 30 , the second portion 512 is clamped between the first front side panel 20 and the second front side panel 30 , thereby achieving the connection between the connecting strip 50 and the first front side panel 20 and the second front side panel 30 .

[0089] After the housing 1 is assembled, the first portion 511 is located between the grid plate 40 and the first body 31. By setting the first portion 511 to have a concave cross-section, when the housing 1 is assembled, the first portion 511 is away from the front end surface of the first front side plate 20 and is flush with the front end surface of the grid plate 40 away from the first front side plate 20 and the first body 31. Figure 3 As shown, the width of the wall where the concave side of the first portion 511 is located matches the thickness of the grid plate 40, so that the front side end of the shell 1 is a smooth plane.

[0090] Furthermore, in this embodiment, the sum of the width of the first portion 511 , the width of the grid plate 40 , and the width of the first body 31 matches the length of the cover plate 10 .

[0091] The height of the grid plate 40 matches the height of the first body 31 and the connecting strip 50. The height of the first front side plate 20 is greater than the heights of the three. In this embodiment, the height of the first front side plate 20 matches the sum of the height of the first body 31 and the height of the side wall of the fourth body 11.

[0092] like Figure 6 As shown, in some embodiments, the shell 1 further includes a middle partition 60, which is disposed in the shell and vertically arranged between the cover plate 10 and the bottom plate 20, so as to divide the space in the shell into two adjacent chambers.

[0093] Specifically, the middle partition 60 includes a plate-shaped third main body 61 and a plate-shaped third connecting portion 62. The third main body 61 is arranged perpendicularly to the third connecting portion 62, and the third connecting portion 62 overlaps with a portion of the first front side plate 20, so that the third main body 61 is arranged perpendicularly to the first front side plate 20 after assembly. At least one fifth connecting hole 621 is also formed on the third connecting portion 62. The second connecting structure 35 and / or the third connecting structure 52 are detachably inserted into the fifth connecting hole 621.

[0094] By providing the third connecting portion 62 and the fifth connecting hole 621, when the first front side plate 20, the second front side plate 30 and the connecting strip 50 are assembled, the middle partition plate 60 is also assembled with the three, thereby enhancing the firmness between the three and further reducing the number of screws and other connecting parts.

[0095] In this embodiment, since the number of the second connection structures 35 and the number of the third connection structures 52 are both plural, the number of the fifth connection holes 621 is also plural, and can be flexibly adjusted.

[0096] In this embodiment, the number of the fifth connection holes 621 matches the number of the fourth connection holes 22, and the two correspond one to one. Each third connection structure 52 is inserted into the fourth connection hole 22 and the fifth connection hole 621. The size of the third connection portion 62 is such that after the housing 1 is assembled, the third connection portion 62 will not block the second connection hole 21 and the third connection hole 5121.

[0097] Specifically, the fifth connection hole 621 is larger than the fourth connection hole 22, with a width slightly larger than the width of the fourth hole portion 222, and a length slightly larger than the sum of the lengths of the third hole portion 221 and the fourth hole portion 222, so as to ensure the convenience of the third connection structure 52 to be installed.

[0098] It should be understood that, in order to ensure the stability of the connection between the middle partition 60 and the shell, several screws can be added between the first front side plate 20 and the third connecting portion 62 to prevent the middle partition 60 from shaking or falling off in the shell. At the same time, the supporting performance of the middle partition 60 can be improved, and equipment can be installed on the middle partition 60. At this time, since the outer side of the middle partition 60 is provided with the connecting strip 50, the grid plate 40, the shielding portion 121 of the cover plate 10, etc., it can achieve a better decorative effect and prevent the screws between the middle partition 60 and the first front side plate 20 from being exposed.

[0099] In some other optional embodiments, since the second connection hole 21 and the fourth connection hole 22 are disposed at relatively close positions on the first front side plate 20, the size of the fifth connection hole 621 can also be adjusted to cover two adjacent second connection holes 21 and fourth connection holes 22. During the assembly process, the second connection structure 35 and the third connection structure 52 can be simultaneously inserted into the fifth connection hole 621.

[0100] In some other optional embodiments, the third connection portion 62 is arranged at a position and a size such that, after the housing 1 is assembled, it only overlaps with the overlapping portions of the first front side plate 20 and the second front side plate 30. At this time, the fifth connection hole 621 corresponds to the second connection hole 21 and the third connection hole 5121, and only the second connection structure 35 is inserted into the fifth connection hole 621.

[0101] In this embodiment, the third connection portion 62 is longitudinally arranged, and its height is substantially equal to that of the first front side plate 20 and the second front side plate 30 .

[0102] In some other optional embodiments, the height of the third connection portion 62 may be smaller than the height of the first front side plate 20 and the second front side plate 30. Or the third connection portion 62 is provided with a plurality of small plates, each of which is provided with a fifth connection hole 621, corresponding to different fourth connection holes 22. The number of small plates may also be smaller than the number of fourth connection holes 22.

[0103] It is important to understand that, except Figure 1 In addition to the heat pump host shown, the housing 1 can also be applied to other heat pump hosts.

[0104] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
