[0032] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0033] Figure 1 The heat pump main unit in one embodiment of the utility model is shown, which includes a housing 1 and a heat pump system arranged in the housing 1. Figures 2 to 5 The housing 1 includes a first front side plate 30, a second front side plate 40 and a connecting strip 50. The three are detachably connected to facilitate assembly or maintenance of the heat pump host.

[0034] Specifically, the first front side plate 30 and the second front side plate 40 are partially overlapped. Together, they constitute the front side plate of the housing 1. At least one first connection hole 31 is formed at the portion where the first front side plate 30 overlaps the second front side plate 40. The connecting strip 50 is partially located between the first front side plate 30 and the second front side plate 40, and is formed with at least one second connection hole 5121. The second connection hole 5121 corresponds to the first connection hole 31.

[0035] The second front side plate 40 includes a first main body 41 and at least one first connection structure 43. The first connection structure 43 is disposed at a portion where the first main body 41 overlaps the first front side plate 30 and is detachably inserted into the first connection hole 31 and the second connection hole 5121.

[0036] The first connection structure 43 may include a first part and a second part, and the first part and the second part each include two opposite ends. The first end of the first part is connected to the first body 41, the second part is spaced apart from the first body 41, the first end of the second part is connected to the second end of the first part, and the second part extends upward from the second end of the first part.

[0037] By setting the first connection structure 43, the first connection hole 31 and the second connection hole 5121, the first front side plate 30, the second front side plate 40 and the connection strip 50 are detachably connected. During the assembly process, it is only necessary to insert the first connection structure 43 into the first connection hole 31 and the second connection hole 5121 to achieve the assembly of the three. The number of screws and other connecting parts provided on the shell 1 is reduced, thereby shortening the disassembly and assembly time, thereby reducing 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.

[0038] By setting the first part and the second part of the first connecting structure 43, during the assembly process, they can be inserted into the first connecting hole 31 and the second connecting hole 5121 in sequence, and then the second front side plate can be pushed in the extension direction of the second part, so that the second part can be abutted against the first front side plate 30 and the connecting strip 50 and cannot be removed by itself, thereby achieving the effect of assembling the three. When disassembling, the second front side plate 30 can slide downward by its own gravity.

[0039] It should be understood that “the connection strip 50 is partially located between the first front side plate 30 and the second front side plate 40” means that the connection strip 50 is sandwiched between the overlapping portions of the first front side plate 30 and the second front side plate 40. The second connection hole 5121 is located on the portion where the connection strip 50 is sandwiched between the overlapping portions of the first front side plate 30 and the second front side plate 40, so that the second connection hole 5121 corresponds to the first connection hole 31. This ensures that the first connection structure 43 can be simultaneously inserted into the first connection hole 31 and the second connection hole 5121.

[0040] It should be understood that the second part "extends upward from the second end of the first part" can be understood as the second part extending in the direction of the cover plate 10 and there is a certain angle between the extension direction of the second part and the direction indicated by the line connecting the two opposite ends of the first part.

[0041] For example, when the extension direction of the second portion is perpendicular to the direction indicated by the line connecting the two opposite segments of the first portion, and the first portion is perpendicular to the plane where the first body 41 is located, Figure 1 and Figure 2 At the angle shown, the second portion can be arranged vertically or tilted at other angles.

[0042] In this embodiment, the housing 1 is in a cubic shape as a whole, and the first front side plate 30 and the second front side plate 40 are both roughly rectangular. Figure 1 and Figure 2 At the angle shown, the two are arranged adjacent to each other on the left and right and partially overlap.

[0043] The housing 1 further includes a cover plate 10, a bottom plate 20 and other side plates. The other side plates are detachably connected to the first front side plate 30 and the second front side plate 40, and together form the circumferential side plates of the housing 1. The cover plate 10 is detachably covered on the top end of the circumferential side plate. The bottom plate 20 is detachably arranged on the bottom end of the circumferential side plate. The cover plate 10, the bottom plate 20, the other side plates, the first front side plate 30 and the second front side plate 40 together constitute the outer shell of the housing 1.

[0044] 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.

[0045] In some other optional embodiments, other side panels, the cover plate 10 and the bottom plate 20 may also be an integrally formed structure.

[0046] 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 30 and the second front side plate 40 may be correspondingly set to other shapes such as irregular shapes, three-dimensional arc plates, etc.

[0047] Furthermore, if Figure 4and Figure 5 As shown, in some embodiments, the first connection structure 43 is in an L-shaped sheet shape and is perpendicular to the first body 41. That is, the first connection structure 43 is vertically arranged on the first body 41. One end of the short side of the L-shape is connected to the first body 41 and is perpendicular to the plane where the first body 41 is located, and is horizontally (in Figure 1 and Figure 2 The L-shaped long side extends upward from the other end (free end) of the L-shaped short side and is parallel to the plane where the first body 41 is located.

[0048] It should be understood that “extending upward” here means extending in the direction of the cover plate 10 , that is, the long side of the L-shape extends from the other end of the short side of the L-shape in the direction close to the cover plate 10 .

[0049] It should be understood that the first portion and the second portion are two sides of the L. In this embodiment, the short side of the L is the first portion of the first connection structure 43, and the long side of the L is the second portion of the first connection structure 43.

[0050] The L-shaped structure of the first connection structure 43 allows, during the assembly process, the first connection structure 43 only needs to be horizontally pushed into the first connection hole 31 and the second connection hole 5121, and then the second front side plate 40 is pushed upward as a whole, so that at least part of the L-shaped long side of the first connection structure 43 can be abutted against the first front side plate 30 and the connecting strip 50. At this time, the first connection structure 43 cannot horizontally escape from the first connection hole 31 and the second connection hole 5121. The second front side plate 40, the first front side plate 30 and the connecting strip 50 are assembled.

[0051] In this embodiment, the second front side panel 40 is also fixed to other side panels (not the first front side panel 30) by screws and other connecting parts. Therefore, during assembly, after the second front side panel 40 is pushed up and assembled with the first front side panel 30 and the connecting strip 50, 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 40 and the other side panels are removed, the second front side panel 40 will automatically slide downward due to its own gravity. After the second front side panel 40 slides down, its first connecting structure 43 is all at a height position corresponding to the first connecting hole 31 and the second connecting hole 5121. At this time, the second front side panel 40 can be easily moved to complete the first connecting structure 43 from the first connecting hole 31 and the second connecting hole 5121.

[0052] In some other optional embodiments, the L-shaped long side of the first connection structure 43 may also extend downward (or away from the first front side plate 30) from the other end of the L-shaped short side. In this case, during the assembly process, after the first connection structure 43 is horizontally pushed into the first connection hole 31 and the second connection hole 5121, the second front side plate 40 is pushed downward as a whole (or pushed toward the first front side plate 30) to complete the assembly.

[0053] In some other optional embodiments, the first connection structure 43 may also be configured as an L-shaped column or other shapes.

[0054] Correspondingly, the first connection hole 31 includes a first hole portion 311 and a second hole portion 312 connected in the longitudinal direction (vertical direction). The first hole portion 311 and the second hole portion 312 are both arranged in a longitudinally long rectangular shape. The first hole portion 311 is located above the second hole portion 312. The width of the first hole portion 311 is adapted to the thickness of the first connection structure 43 and is smaller than the width of the second hole portion 312. The sum of the lengths of the first hole portion 311 and the second hole portion 312 should be greater than the length of the long side of the L-shape of the first connection structure 43.

[0055] The first connection hole 31 has different widths in the vertical direction, which can be matched with the L-shaped sheet structure of the first connection structure 43. After the first front side plate 30 and the second front side plate 40 are assembled, the L-shaped short side of the first connection structure 43 can be clamped in the first hole portion 311, thereby improving the firmness of the two after assembly.

[0056] It should be understood that, for the first connection structure 43 with other structures or other setting angles, the setting angles and sizes of the first hole portion 311 and the second hole portion 312 can be adaptively adjusted.

[0057] Since the connecting strip 50 is partially sandwiched between the first front side plate 30 and the second front side plate 40, the second connecting hole 5121 is located between the second front side plate 40 and the first front side plate 30 (the first connecting hole 31). During the assembly process, the first connecting structure 43 first passes through the second connecting hole 5121 and then passes through the first connecting hole 31. For ease of assembly, in this embodiment, the second connecting hole 5121 is arranged in a longitudinally long rectangular shape. Figure 5 As shown, its width is matched with the width of the second hole portion 312 of the first connecting hole 31 , and its length is slightly larger than the sum of the lengths of the first hole portion 311 and the second hole portion 312 .

[0058] In some other optional embodiments, the width of the second connection hole 5121 may be slightly larger or smaller than the width of the second hole portion 312. Its shape may also be set to be the same as the first connection hole 31. It should be understood that the shape and size of the second connection hole 5121 and the first connection hole 31 may also be flexibly set, which can allow the first connection structure 43 to pass through.

[0059] Continue reading Figure 5 In some embodiments, the second front side plate 40 further includes a second connecting portion 42, which is arranged in a longitudinal plate shape. The height is adapted to the height of the first main body 41, and the width is narrow. It is connected to the side of the first main body 41 close to the first front side plate 30 and is perpendicular to the first main body 41. The first connecting structure 43 is connected to the second connecting portion 42, and is arranged on the first main body 41 through the second connecting portion 42, and the first connecting structure 43 and the second connecting portion 42 are on the same plane.

[0060] By providing the second connection portion 42, the connection area between the plane where the first connection structure 43 is located and the first body 41 can be expanded, and the connection strength of the first connection structure 43 can be strengthened, so as to avoid the first connection structure 43 and the first body 41 from breaking after the heat pump host is used for a long time or the shell 1 is disassembled and assembled many times.

[0061] In this embodiment, the number of the first connection structures 43 is multiple, and they are evenly spaced and arranged on the side of the second connection portion 42 away from the first body 41, so as to improve the firmness of the assembly between the second front side plate 40 and the first front side plate 30 and the connection strip 50. Correspondingly, the number of the first connection holes 31 and the second connection holes 5121 is correspondingly set to multiple.

[0062] like Figure 4 As shown, in some embodiments, the second front side plate 40 further includes at least one third connection structure 45. At least one fifth connection hole 14 is correspondingly formed on the cover plate 10, and the third connection structure 45 is disposed at the top of the first body 41 and detachably penetrates into the fifth connection hole 14.

[0063] During the process of assembling the second front side plate 40, after the first connection structure 43 is horizontally inserted into the first connection hole 31 and the second connection hole 5121, when the second front side plate 40 needs to be pushed up, in addition to the L-shaped long side of the first connection structure 43 moving up to abut against the first front side plate 30, the third connection structure 45 will also be synchronously inserted into the fifth connection hole 14 during the pushing-up process. That is, the second front side plate 40 and the cover plate 10 are assembled synchronously, further reducing the assembly steps of the housing 1.

[0064] Meanwhile, when the heat pump main unit needs to be repaired, after removing the screws between the second front side plate 40 and other side plates, the second front side plate 40 moves downward by its own gravity and can be automatically removed from the cover plate 10. After further removing the second front side plate 40, the components in the housing 1 can be repaired without removing the cover plate 10.

[0065] Specifically, in this embodiment, the third connection structure 45 is in the shape of a plate. The second front side plate 40 further includes a third connection portion 44, which is in the shape of a longitudinal plate, and its length is roughly adapted to the width of the first main body 41, and its width is relatively narrow. The third connection portion 44 is perpendicular to the first main body 41, and one of its long sides is connected to a fixed side of the first main body 41. The third connection structure 45 is in the shape of a sheet, connected to the other long side of the third connection portion 44, and connected to the first main body 41 through the third connection portion 44. The third connection structure 45 and the third connection portion 44 are on the same plane.

[0066] Read also Figure 1 In this embodiment, the housing 1 further includes a grid plate 70, which is overlapped with a portion of the first front side plate 30 and is used to block the vents on the first front side plate 30 to prevent larger foreign objects from entering. By providing a second connecting portion 42 and a third connecting portion 44 perpendicular to the first body 41, the thickness of the second front side plate 40 is greater than that of the first front side plate 30. Figure 7 At this time, the front end surface of the assembled second front side plate 40 can be flush with the front end surface of the grid plate 70 located at the front end of the first front side plate 30, ensuring the smoothness of the outer contour of the shell and reducing bump damage.

[0067] In this embodiment, the third connection structures 45 are multiple in number and are arranged at intervals on the side of the third connection portion 44 away from the first body 41 to improve the firmness of the assembly between the second front side plate 40 and the cover plate 10. The cover plate 10 is provided with multiple fifth connection holes 14 correspondingly.

[0068] Continue reading Figure 7 Correspondingly, the cover plate 10 includes a fourth main body 11, a first extension portion 12 and a fourth connecting portion 13. The fourth main body 11 includes a rectangular top wall and a side wall arranged around the top wall. The first extension portion 12 and the fourth connecting portion 13 are both in the shape of a rectangular plate. The outer side of the first extension portion 12 is connected to the bottom side of the side wall of the fourth main body 11 and is perpendicular to the side wall of the fourth main body 11. The top side of the fourth connecting portion 13 is connected to the inner side of the first extension portion 12, is perpendicular to the first extension portion 12, and is parallel to the side wall of the fourth main body 11.

[0069] The fifth connection hole 14 is formed at a connection point between the first extension portion 12 and the fourth connection portion 13 .

[0070] During the assembly of the second front side plate 40 and the cover plate 10, the third connection structure 45 is gradually inserted into the fifth connection hole 14, and the fourth connection portion 13 is gradually relatively moved to the bottom of the third connection portion 44 until the first extension portion 12 overlaps and contacts the third connection portion 44. At this time, the side wall of the fourth body 11, the grid plate and the first body 41 are all on the same plane, and the bottom end of the side wall of the fourth body 11 is connected to the top of the grid plate and the top of the first body 41 respectively.

[0071] The height of the grid plate 70 matches the height of the first body 41 and the connecting strip 50. The height of the first front side plate 30 is greater than the heights of the three. In this embodiment, the height of the first front side plate 30 matches the sum of the height of the first body 41 and the height of the side wall of the fourth body 11.

[0072] In some other optional embodiments, the height of the first front side plate 30 may also be slightly smaller than the sum of the height of the first body 41 and the height of the side wall of the fourth body 11 .

[0073] In some embodiments, after the first front side plate 30, the second front side plate 40, the connecting strip 50 and the cover plate 10 are assembled, the first extension portion 12 is arranged in contact with the third connection portion 44 and the top of the grid plate 70, and the fourth connection portion 13 is located at the lower side of the first extension portion 12. Therefore, the inner side surface at the top of the grid plate 70 is also recessed toward the outer side surface to form a clearance groove (not shown in the figure) for making way for the fourth connection portion 13.

[0074] In some other optional embodiments, the fourth connection portion 13 may also be provided only at a position corresponding to the second front side plate 40. The fourth connection portion 13 and the third connection portion 44 may also not be provided, the fifth connection hole 14 may be provided at a position where the first extension portion 12 is connected to the fourth body 11, and the third connection structure 45 may be provided at the top of the first body 41.

[0075] For example Figure 4 and Figure 5 As shown, in some embodiments, the connecting strip 50 includes a second body 51 and at least one second connecting structure 52, the second connecting hole 5121 is formed on the second body 51, and the second connecting structure 52 is disposed on the second body 51. The first front side plate 30 also includes at least one third connecting hole 32, and the second connecting structure 52 is detachably inserted into the third connecting hole 32, so that the connecting strip 50 and the first front side plate 30 are detachably connected. This improves the firmness of the assembly between the first front side plate 30, the second front side plate 40 and the connecting strip 50.

[0076] Specifically, the second connection structure 52 includes a third part and a fourth part connected to each other, and the third part and the fourth part each include two opposite ends. The first section of the third part is connected to the second body 51. The fourth part is spaced apart from the second body 51, and its first end is connected to the second end of the third part and extends to one side from the second end of the third part.

[0077] It should be understood that the third portion and the fourth portion of the second connection structure 52 are similar to the first portion and the second portion of the first connection structure 43 , and are not described in detail herein.

[0078] In this embodiment, the second connection structure 52 is generally in the shape of an L-shaped sheet. Its L-shaped short side is perpendicular to the second body 51, extends horizontally, and one end is connected to the second body 51. Its L-shaped long side is connected to the other end (free end) of the L-shaped short side and extends downward. The axis of its L-shaped long side is parallel to the plane where the second body 51 is located.

[0079] It should be understood that, in this embodiment, the L-shaped short side of the second connecting structure 52 is the third portion, and the L-shaped long side is the fourth portion.

[0080] The L-shaped sheet structure of the second connection structure 52 allows the second connection structure 52 to be horizontally moved into the third connection hole 32 during the assembly of the connection bar 50 and the first front side plate 30. The connection bar 50 is then moved downward so that the L-shaped long side of the second connection structure 52 is located outside the third connection hole 32 and abuts against the first front side plate 30, thereby achieving assembly of the two. The process is convenient and quick.

[0081] At the same time, since the second connection structure 52 is in an L-shaped sheet shape with the long side extending downward, and the first connection structure 43 is in an L-shaped sheet shape with the long side extending upward, when the first front side plate 30, the second front side plate 40 and the connection strip 50 are assembled, the force direction between the connection strip 50 and the first front side plate 30 and the force direction between the second front side plate 40 and the first front side plate 30 and the connection strip 50 are opposite, so the firmness of the assembly between the three can be further improved.

[0082] It should be understood that “extending downward” refers to extending toward the bottom plate 20 . That is, the long side of the L-shape extends from the other end of the short side of the L-shape toward the bottom plate 20 .

[0083] In some other optional embodiments, the L-shaped long side of the second connection structure 52 may be horizontally arranged, and the L-shaped short side may extend downward from the free end of the L-shaped long side. Similarly, the first connection structure 43 may also be horizontally arranged, and the L-shaped short side may extend upward from the free end of the L-shaped long side.

[0084] In some other optional embodiments, the second connection structure 52 may also be configured as an L-shaped column or other shapes.

[0085] It should be understood that the shapes of the first connecting structure 43 and the second connecting structure 52 are not limited to the L-shape formed by two straight edges, and there may also be slight deformations such as bending, and they can be roughly L-shaped. The angle at which they are set may not make the two straight edges respectively set horizontally and vertically, and there may also be a slight tilt. The two parts of the first connecting structure 43 and the second connecting structure 52 may not be set to be perpendicular to each other, and the angle between the two may be slightly greater than or less than 90°. The shape and setting angle of the first connecting structure 43 (or the second connecting structure 52) can achieve the assembly function, and the specific details are not limited.

[0086] Further, the third connection hole 32 includes a third hole portion 321 and a fourth hole portion 322 connected in the longitudinal direction (vertical direction), and the third hole portion 321 is located below the fourth hole portion 322. The width of the third hole portion 321 is adapted to the thickness of the second connection structure 52 and is smaller than the width of the fourth hole portion 322. The sum of the lengths of the third hole portion 321 and the fourth hole portion 322 should be greater than the length of the L-shaped long side of the second connection structure 52.

[0087] The third connection hole 32 has different widths in the vertical direction, which can be matched with the L-shaped sheet structure of the second connection structure 52. After the connection strip 50 and the first front side plate 30 are assembled, the L-shaped short side of the second connection structure 52 can be clamped in the third hole 321, thereby improving the firmness of the two after assembly.

[0088] It should be understood that, for the second connection structure 52 with other structures or other setting angles, the setting angles and sizes of the third hole portion 321 and the fourth hole portion 322 can be adaptively adjusted.

[0089] Specifically, Figure 6 As shown, in this embodiment, the second body 51 includes a protrusion 511 and a connecting portion 512. The protrusion 511 and the connecting portion 512 are both arranged in a longitudinal direction and have the same length. The horizontal cross-section of the protrusion 511 is a rectangle with one end open, and the connecting portion 512 is in a sheet shape. One side of the connecting portion 512 is vertically connected to one side of the protrusion 511. The second connecting hole 5121 is formed on the connecting portion 512. The second connecting hole 5121 is formed on the connecting portion 512. The second connecting structure 52 is arranged on the side end of the protrusion 511 away from the connecting portion 512.

[0090] The structural arrangement of the second main body 51 enables, when the connecting strip 50 is assembled with the first front side plate 30 and the second front side plate 40 , the connecting portion 512 is clamped between the first front side plate 30 and the second front side plate 40 , thereby realizing the connection between the connecting strip 50 and the first front side plate 30 and the second front side plate 40 .

[0091] After the housing 1 is assembled, the protrusion 511 is located between the grid plate 70 and the first body 41. By setting the protrusion 511 to be a rectangular cross section with one end open, when the housing 1 is assembled, the protrusion 511 is away from the front end surface of the first front side plate 30 and is flush with the front end surface of the grid plate 70 away from the first front side plate 30 and the first body 41. That is, the front side end of the housing 1 is a smooth plane.

[0092] Furthermore, in this embodiment, the sum of the width of the protrusion 511 , the width of the grid plate 70 , and the width of the first body 41 matches the length of the cover plate 10 .

[0093] like Figure 3 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.

[0094] Read also Figure 5 Specifically, the middle partition 60 includes a plate-shaped third main body 61 and a plate-shaped first connecting portion 62. The third main body 61 is arranged perpendicularly to the first connecting portion 62, and the first connecting portion 62 overlaps with a portion of the first front side plate 30, so that the third main body 61 is arranged perpendicularly to the first front side plate 30 after assembly. At least one fourth connecting hole 621 is also formed on the first connecting portion 62. The first connecting structure 43 and / or the second connecting structure 52 are detachably inserted into the fourth connecting hole 621.

[0095] By providing the first connecting portion 62 and the fourth connecting hole 621, when the first front side plate 30, the second front side plate 40 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.

[0096] In this embodiment, since the number of the first connection structures 43 and the number of the second connection structures 52 are both plural, the number of the fourth connection holes 621 is also plural, and can be flexibly adjusted.

[0097] In this embodiment, the number of the fourth connection holes 621 matches the number of the third connection holes 32, and the two correspond one to one. Each second connection structure 52 is inserted into the third connection hole 32 and the fourth connection hole 621. The size of the first connection portion 62 is such that after the housing 1 is assembled, the first connection portion 62 will not block the first connection hole 31 and the second connection hole 5121.

[0098] Specifically, the fourth connection hole 621 is larger than the third connection hole 32. The width is slightly larger than the width of the fourth hole portion 322, and the length is slightly larger than the sum of the lengths of the third hole portion 321 and the fourth hole portion 322, so as to ensure the convenience of the second connection structure 52 to pass through.

[0099] 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 30 and the first 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 a connecting strip 50, a grid plate 70, etc. for shielding, it can achieve a better decorative effect and prevent the screws between the middle partition 60 and the first front side plate 30 from being exposed.

[0100] In some other optional embodiments, since the first connection hole 31 and the third connection hole 32 are disposed at relatively close positions on the first front side plate 30, the size of the fourth connection hole 621 can also be adjusted to cover two adjacent first connection holes 31 and third connection holes 32. During the assembly process, the first connection structure 43 and the second connection structure 52 can be simultaneously inserted into the fourth connection hole 621.

[0101] In some other optional embodiments, the first 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 30 and the second front side plate 40. At this time, the fourth connection hole 621 corresponds to the first connection hole 31 and the second connection hole 5121, and only the first connection structure 43 is inserted into the fourth connection hole 621.

[0102] In this embodiment, the first connecting portion 62 is longitudinally arranged, and its height is substantially equal to that of the first front side plate 30 and the second front side plate 40 .

[0103] In some other optional embodiments, the height of the first connection portion 62 may be smaller than the height of the first front side plate 30 and the second front side plate 40. Or the first connection portion 62 is provided with a plurality of small plates, each of which is provided with a fourth connection hole 621, corresponding to different third connection holes 32. The number of small plates may also be smaller than the number of third connection holes 32.

[0104] 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.

[0105] 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.
