Description

Technical Field

[0001] This utility model relates to the field of refrigeration and air conditioning technology, and in particular to an installation structure for a heat pump unit. Background Technology

[0002] After the heat pump unit is installed, its internal water system has completed the laying and connection of all pipes. These pipes are embedded inside the casing and connected to the core components of the heat pump unit, such as the compressor and heat exchanger, forming a complete circulation system. However, when the equipment malfunctions and requires after-sales maintenance, maintenance personnel must first open the casing and then disassemble the water system pipes. This disassembly process involves many steps and consumes a significant amount of time. After the maintenance of the internal components is completed, the pipes must be re-laid and reconnected, which is equally cumbersome. Therefore, maintenance of the unit is very inconvenient and reduces the efficiency of after-sales maintenance. Utility Model Content

[0003] In order to overcome at least one of the defects described in the prior art, the present invention provides an installation structure for a heat pump unit that is easy to assemble and disassemble and facilitates later maintenance.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] An installation structure for a heat pump unit includes a housing and a cover plate. The housing has an installation cavity and an installation port, the installation port being in communication with the installation cavity, and the cover plate being detachably sealed to the installation port.

[0006] The cover plate includes a first plate segment and a second plate segment, wherein the first plate segment is provided with a first connecting part and a splicing notch;

[0007] The second plate segment is provided with a second connecting part and a positioning part. The second plate segment is spliced ​​to the splicing notch and is detachably connected to the first connecting part through the second connecting part; the positioning part is in communication with the mounting cavity.

[0008] Furthermore, the first connecting part includes a snap-fit ​​piece, which extends toward the splicing notch; the second connecting part includes a snap-fit ​​slot, which corresponds to the snap-fit ​​piece and snaps into the snap-fit ​​slot.

[0009] Furthermore, the snap-fit ​​piece is provided with a guide surface, which slides in conjunction with the snap-fit ​​slot and guides the snap-fit ​​piece to snap into the snap-fit ​​slot.

[0010] Furthermore, the end wall of the splicing notch is provided with a positioning notch, and the snap-fit ​​piece is disposed in the positioning notch and spaced apart from the side wall of the positioning notch.

[0011] Furthermore, the second plate segment is provided with a connecting edge, which includes a first segment and a second segment. The first segment is bent perpendicularly to the end wall of the second plate segment, and the second segment is bent perpendicularly to the first segment.

[0012] The first segment is used to abut against the end wall of the splicing notch when the second plate segment is installed in the splicing notch, and the second segment abuts against the first plate segment; the first connecting part is provided on the first segment.

[0013] Furthermore, the first plate segment is provided with a third connecting part, and the second segment is provided with a fourth connecting part, wherein the fourth connecting part and the third connecting part are detachably connected.

[0014] Furthermore, there are multiple third connecting parts, which are spaced apart around the periphery of the splicing notch; there are multiple fourth connecting parts, which are arranged in a one-to-one correspondence with the multiple third connecting parts.

[0018] In summary, the installation structure of the heat pump unit provided by this utility model has the following technical effects:

[0019] In practical use, the positioning part on the second plate section limits and fixes the water system pipeline, ensuring its stability during equipment operation. When a component inside the installation cavity malfunctions and requires maintenance, simply detach the first and second plate sections, allowing maintenance personnel unimpeded access to the cavity.

[0036] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0037] See Figures 1 to 8 This utility model discloses an installation structure for a heat pump unit, including a housing 10 and a cover plate 20. The housing 10 has an installation cavity 11 and an installation port 12, which are connected to the installation cavity 11. The cover plate 20 is detachably sealed to the installation port 12. The cover plate 20 includes a first plate segment 21 and a second plate segment 22. The first plate segment 21 is provided with a first connecting part 212 and a splicing notch 211. The second plate segment 22 is provided with a second connecting part 221 and a positioning part 222. The second plate segment 22 is spliced ​​to the splicing notch 211 and is detachably connected to the first connecting part 212 through the second connecting part 221. The positioning part 222 is connected to the installation cavity 11.

[0038] In the actual assembly process, the user first installs the core heat pump components, such as the compressor, evaporator, and condenser, into the mounting cavity 11 in an orderly manner through the mounting port 12, and then completes the connection between the water system pipes and the heat pump product. Next, the second plate segment 22 is embedded into the splicing notch 211 of the first plate segment 21, and connected to the first plate segment 21 through the second connecting part 221 on the second plate segment 22, so that the first plate segment 21 and the second plate segment 22 combine to form a complete cover plate 20, which seals the mounting port 12. At this time, the water pipes are limited and fixed by the positioning part 222 (such as positioning holes, positioning openings, or positioning grooves) on the second plate segment 22, and after being limited and fixed by the positioning part 222, they extend to the outside of the mounting cavity 11 and connect with external equipment to complete the stable connection of the entire water system.

[0039] When the equipment requires maintenance, the first connecting part 212 and the second connecting part 221 are detachable. Maintenance personnel only need to separate them to remove the first plate segment 21 from the second plate segment 22, partially opening the installation port 12. At this point, maintenance personnel can directly access the installation cavity 11 to inspect the components. During this process, the second plate segment 22 remains firmly partially sealed over the installation port 12. The pipe fixed by the second plate segment 22 remains in place due to the constraint of the positioning part 222, reducing the tedious operation of repeatedly disassembling and reassembling pipes during traditional maintenance. This simplifies the maintenance process, shortens maintenance time, and thus improves the efficiency and convenience of equipment maintenance.

[0040] It should be noted that the first connecting part 212 may be a structure such as an elastic buckle, a snap-fit ​​piece 2121 or a snap block provided on the edge of the splicing notch 211, while the second connecting part 221 is a structure such as a slot or a notch 2211 opened at the corresponding position. During assembly, the buckle elastically deforms and embeds into the slot, so that the first connecting part 212 and the second connecting part 221 are engaged and connected, so as to achieve detachability.

[0041] Of course, the first connecting part 212 can also be a connecting structure such as a through hole or a threaded hole located at the edge of the splicing notch 211, and the second connecting part 221 is a threaded hole or a through hole provided therewith. It is connected to the first connecting part and the second connecting part by connecting parts such as screws or nuts, so that the first connecting part 212 and the second connecting part 221 can be detachably connected.

[0042] Similarly, during installation, the cover plate 20 can also be detachably connected to the housing 10 via snap-fit ​​or threaded connection, allowing it to detachably cover the mounting opening 12. For example, during assembly, snap-fit ​​structures such as clips and snap-fit ​​pieces are provided on the first plate segment 21 and the second plate segment 22, and simultaneously, slots or grooves are provided on the housing 10 near the edge of the mounting opening 12, so that the first plate segment 21 and the second plate segment 22 are detachably connected to the housing 10, thus allowing the cover plate 20 to detachably cover the mounting opening 12. In this way, when the first plate segment 21 and the second plate segment 22 are removed, the connection between the second plate segment 22 and the housing 10 will not be affected, allowing the pipeline to remain in its original position during maintenance.

[0043] Preferably, in this embodiment, the first connecting portion 212 includes a snap-fit ​​piece 2121, which extends toward the splicing notch 211. The second connecting portion 221 includes a bayonet 2211. During assembly, the snap-fit ​​piece 2121 is aligned with the bayonet 2211 and snapped into it. Compared to threaded connections, the snap-fit ​​piece 2121 and bayonet 2211 do not require additional tools and can be disassembled by hand, making assembly and disassembly more convenient.

[0044] It should be noted that the snap-fit ​​piece 2121 in this embodiment can be made of a material with a certain strength and elastic deformation capability, such as stainless steel, aluminum alloy or spring steel. One end of the snap-fit ​​piece 2121 is fixed to the first plate segment 21, and the other end extends toward the assembly notch, so that it can undergo elastic deformation when subjected to force and be successfully snapped into the slot 2211. After the external force is removed, it can be locked in the slot 2211 and is not easy to loosen.

[0045] More specifically, the snap-fit ​​piece 2121 is provided with a guide surface, which can be inclined or curved. In this way, when the snap-fit ​​piece 2121 is inserted into the slot 2211, the guide surface and the edge of the slot 2211 form sliding friction, which decomposes the vertical insertion force into a horizontal thrust and a vertical pressure, guiding the snap-fit ​​piece 2121 to align with the slot 2211 and making it easier to slide into the slot 2211.

[0046] Furthermore, the end wall of the splicing notch 211 is provided with a positioning notch 214, and the snap-fit ​​piece 2121 is provided in the positioning notch 214 and is spaced apart from the side wall of the positioning notch 214.

[0047] Specifically, since both sides of the snap-fit ​​piece 2121 are spaced apart from the sidewalls of the positioning notch 214, a gap is left between the two sides of the snap-fit ​​piece 2121 and the sidewalls of the positioning notch 214. This gap allows the snap-fit ​​piece 2121 to form an independent structure. When the snap-fit ​​piece 2121 is inserted into or disengaged from the latch 2211, only local elastic deformation is required to complete the engagement or disengagement action. This reduces the force required for the snap-fit ​​piece 2121 to deform, thereby reducing the difficulty of deformation and making assembly and disassembly easier.

[0048] Furthermore, the second plate segment 22 is provided with a connecting edge 223, which includes a first segment 2231 and a second segment 2232. The first segment 2231 is bent perpendicularly to the end wall of the second plate segment 22, and the second segment 2232 is bent perpendicularly to the first segment 2231. When the second plate segment 22 is installed at the splicing notch 211, the first segment 2231 abuts against the end wall of the splicing notch 211, and the second segment 2232 abuts against the first plate segment 21. The first connecting part 212 is provided on the first segment 2231.

[0049] Specifically, during installation, when the second plate segment 22 is inserted into the assembly notch, the abutment of the first segment 2231 against the end wall of the assembly notch 211 provides an initial positioning reference for the second plate segment 22. At this time, the first connecting part 212 (clamping piece 2121) located at the edge of the assembly notch and the second connecting part 221 (clamping slot 2211) automatically align, making it easier for operators to quickly connect the first connecting part 212 and the second connecting part 221, making the operation more convenient.

[0050] Meanwhile, after the second plate segment 22 is connected to the first plate segment 22, the first segment 2231 abuts against the end wall of the assembly notch, restricting the axial displacement of the second plate segment 22; at the same time, the second segment 2232 abuts against the first plate segment 21, providing additional radial support, thereby increasing the connection area between the second plate segment 22 and the first plate segment 21, making the connection between the second plate segment 22 and the first plate segment 21 tighter and enhancing the connection stability.

[0051] Furthermore, the first plate segment 21 is provided with a third connecting part 213, and the second segment 2232 is provided with a fourth connecting part 2233, and the fourth connecting part 2233 is detachably connected to the third connecting part 213.

[0052] Specifically, in order to strengthen the connection between the first plate segment 21 and the second plate segment 22, a third connecting part 213 is provided on the first plate segment 21. When the second plate segment 22 is assembled to the splicing gap 211, the fourth connecting part 2233 on the second segment 2232 of the connecting edge 223 connects with the third connecting part 213, realizing the double locking of the first plate segment 21 and the second plate segment 22, making the connection between the two more secure and improving the stability of the cover plate 20 structure.

[0053] It should be noted that the third connecting part 213 can be an elastic buckle, a snap-fit ​​piece 2121 or a snap-fit ​​block near the edge of the splicing notch 211, while the fourth connecting part 2233 is a slot or a notch provided on the second segment 2232. During assembly, the buckle elastically deforms and embeds into the slot, so that the first connecting part 212 and the second connecting part 221 engage and connect, thus achieving detachability.

[0054] Of course, the third connecting part 213 can also be a connecting structure such as a through hole or a threaded hole located at the edge of the splicing notch 211, while the fourth connecting part 2233 is a corresponding threaded hole or a through hole, and the third connecting part 213 and the fourth connecting part 2233 can be detachably connected by screws or nuts or other connecting parts.

[0055] More specifically, multiple third connecting parts 213 are provided, and these multiple third connecting parts 213 are spaced apart around the periphery of the splicing notch 211; multiple fourth connecting parts 2233 are provided, and these multiple fourth connecting parts 2233 are arranged one-to-one with the multiple third connecting parts 213. By connecting the multiple spaced third connecting parts 213 and the fourth connecting parts 2233, multi-point locking between the connecting edge 223 and the first plate segment 21 is achieved, thereby further increasing the connection strength between the second plate segment 22 and the first plate segment 21, and thus improving the stability of the connection between the second plate segment 22 and the first plate segment 21.

[0056] Preferably, in this embodiment, the third connecting part 213 includes a first mounting hole, and the fourth connecting part 2233 includes a second mounting hole. The second mounting hole is correspondingly provided with the first mounting hole. During assembly, after the first connecting part 212 and the second connecting part 221 are connected, screws, bolts or other connecting parts are inserted into the first mounting hole and the second mounting hole to further lock the first plate segment 21 and the second plate segment 22.

[0057] Furthermore, at least two connecting edges 223 are provided on the second plate segment 22, and the at least two connecting edges 223 are detachably connected to the first plate segment 21 through the fourth connecting part 2233.

[0058] Specifically, when there are at least two connecting edges 223, the third connecting parts 213 on the first plate segment 21 can be distributed at intervals along the edge of the assembly notch, so that after the second plate segment 22 is assembled to the first plate segment 21, the fourth connecting part 2233 on each connecting piece can be connected to the third connecting part 213 on the first plate segment 21 to form multiple locking, thereby making the connection between the second plate segment 22 and the first plate segment 21 more secure and improving the stability of the cover plate 20 structure.

[0059] It should be noted that in this embodiment, the connecting edge 223 can be set to two, three or more, depending on the shape of the assembly gap.

[0060] More specifically, in this embodiment, the positioning part 222 includes positioning holes that penetrate the second plate segment 22 to guide the water system pipes in or out. Furthermore, multiple positioning holes are provided, spaced apart on the second plate segment 22, and the number of positioning holes can be specifically set according to the number of pipes.

[0061] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
