Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, specifically to a heat pump unit maintenance component housing and a heat pump unit having the same. Background Technology

[0002] In the fields of building thermal environment and industrial energy conservation, heat pump units have been deployed on a large scale due to their high energy efficiency ratio and multi-energy coupling advantages. With the increasing diversity of building facades and installation scenarios, the unit casing is gradually transitioning from the traditional cuboid to arcs, polyhedrons, and even free-form surfaces to balance aesthetics and space utilization. This trend has placed unprecedented compatibility requirements on detachable maintenance structures. The maintenance panel must not only fit precisely with the irregular contours of the unit body but also meet the complex needs of frequent disassembly and assembly, long-term weather resistance, and safe maintenance.

[0003] Existing access panels generally use a rectangular metal plate with folded edges. Installation primarily involves screws evenly distributed around the perimeter, with some models supplemented by single-sided hinges or simple hooks. When the unit's casing has rounded transitions or chamfered shapes, traditional access panel installation methods struggle to conform to the shape, often resulting in uneven edge gaps, visual discontinuity, and even stress concentration leading to panel deformation and reduced protective performance. Utility Model Content

[0004] In view of this, the present invention provides a heat pump unit maintenance component housing and a heat pump unit having the same, so as to solve the problem in the prior art that the protection performance is reduced when the heat pump unit maintenance component housing is installed on an irregular structure due to the incompatibility of the installation structure.

[0005] In a first aspect, this utility model provides a heat pump unit maintenance component housing, comprising:

[0006] The inspection panel has multiple sets of first latches spaced apart on its parallel two sides.

[0007] The mounting side panels are provided in pairs. The pair of mounting side panels are respectively installed with the two sides of the inspection panel where the first buckle is provided. One side edge of the mounting side panel is provided with a first slot. The first buckle and the first slot are slidably engaged. The first buckle slides relative to the first slot along the edge extension direction of the inspection panel where the first buckle is installed.

[0008] The mounting chassis is provided with connecting flanges, and the mounting side plates are all detachably connected to the connecting flanges.

[0009] The access panel is directionally slidably engaged with the first slots on a pair of mounting side plates via multiple sets of first snap-fits on both sides. As the access panel moves along the edge of the mounting side plate, the first snap-fits slide linearly within the first slots, enabling push-pull assembly and disassembly. The mounting side plates are fixed to the mounting base via detachable connectors, forming a positioning structure that constrains the spatial freedom of the access panel. During assembly, after the pair of mounting side plates are in place on the mounting base, the first snap-fit ​​blocks are installed into the first slots. The access panel is then installed by sliding it along the side of the access panel with the first snap-fits. When the access panel is designed with a special shape with irregular surfaces, it can be installed by aligning the first snap-fits with each other and then sliding a short distance. The irregularly shaped access panel will not be restricted by other structures during installation, ensuring the stability of the connection and thus guaranteeing the protective performance of the heat pump unit's access component housing for the internal access components.

[0010] In one optional embodiment, the side of the inspection panel that mates with the mounting chassis has an arc-shaped folded edge. A bottom fixing plate is fixedly installed between the arc-shaped folded edge and the mounting chassis. A bottom folded edge is provided on one side of the bottom fixing plate, and the bottom fixing plate and the bottom folded edge respectively abut against the two outer edges of the arc-shaped folded edge. This creates a closed cavity between the bottom fixing plate and the arc-shaped folded edge, effectively solving the problem of rust easily caused by galvanized components inside the housing being completely exposed to air.

[0011] In one optional embodiment, the bottom fixing plate and the mounting chassis are fixedly connected by a bottom fastener. A recessed slot is provided on the arc-shaped folded edge, facing the bottom fastener. External tools such as screwdrivers can be inserted through the recessed slot into the inside of the arc-shaped folded edge to operate the bottom fastener, for installation or removal. Simultaneously, the recessed slot also serves as a channel for injecting surface protective paint, providing a spray nozzle for air-jet tools, facilitating the entry of surface protective paint into the cavity between the arc-shaped folded edge and the bottom fixing plate, achieving a rust-preventing effect.

[0012] In one optional embodiment, the width of the bottom fixing plate is smaller than the width of the arc-shaped fold, so that a clearance notch is reserved on the side of the arc-shaped fold facing the bottom fixing plate;

[0013] The bottom of the mounting side plate is provided with a fixed folded edge, which is fixedly connected to the mounting chassis by a fixing fastener, and the fixed folded edge is aligned with the clearance notch.

[0014] This allows the bottom fasteners to extend into the clearance notch, securing the bottom mounting plate tightly to the mounting chassis and ensuring a stable connection between the bottom mounting plate and the mounting side plate.

[0015] In one optional embodiment, the fixed fold completely covers the clearance notch, effectively preventing external dust, moisture, and other foreign objects from entering the housing through the clearance notch, thereby improving the sealing performance and protection level of the equipment and extending its service life. It also prevents animals such as spiders, cockroaches, and geckos from entering the housing through the clearance notch and causing short circuits or corrosion.

[0016] In one optional embodiment, a water guide groove is provided on the side edge of the mounting side plate, and the first slot is provided on the side wall of the water guide groove. By providing the water guide groove, water entering the edge of the mounting side plate can be discharged along the water guide groove under the action of gravity, preventing water from entering the housing from the first slot and causing damage to the internal components of the housing.

[0017] In one optional embodiment, the upper edge of the access panel and / or the mounting side panel has a water-retaining edge. Forming a top waterproof barrier effectively prevents water from entering the housing from above, preventing rainwater or other liquids from seeping into the housing from above, thereby improving the housing's waterproof performance, protecting electrical components and other critical parts inside the housing, and reducing the risk of damage to internal components due to water ingress.

[0018] In one optional embodiment, a mounting cover plate is further included, with a second snap-fit ​​on its edge. A second slot is provided on the side of the mounting side plate opposite to the mounting chassis. The second snap-fit ​​and the second slot are slidably engaged, with the second snap-fit ​​sliding relative to the second slot along the edge of the mounting cover plate where the second snap-fit ​​is mounted. This allows the mounting cover plate to be quickly installed onto the mounting side plate via the slidable engagement of the second snap-fit ​​and the second slot, eliminating the need for additional fasteners, simplifying the installation process, and improving installation efficiency. Simultaneously, the slidable engagement structure ensures a tight connection between the mounting cover plate and the mounting side plate, enhancing the overall integrity and stability of the housing.

[0019] In one optional embodiment, the inspection panel has a pre-drilled mounting opening, and a water-resistant folded edge is provided on the lower side of the mounting opening. This prevents water from entering the inner cavity of the housing through the gaps along the edge of the wired controller, improving the housing's waterproof performance and enhancing its reliability and durability in humid environments.

[0020] Secondly, this utility model also provides a heat pump unit having the heat pump unit maintenance component housing described in this utility model.

[0021] Since the heat pump unit includes the heat pump unit maintenance component housing, which has the same effect as the heat pump unit maintenance component housing, it will not be elaborated here. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0034] According to an embodiment of the present invention, in one aspect, a heat pump unit maintenance component housing is provided, including a maintenance panel 1, a mounting side plate 2, and a mounting chassis 3.

[0035] Multiple sets of first clips 8 are spaced apart on both parallel sides of the inspection panel 1 along the vertical direction. A pair of mounting side plates 2 are provided, each fitting into one of the two sides of the inspection panel 1 where the first clips 8 are located. A first groove 9 is provided on one edge of each mounting side plate 2, and the first clips 8 slide and engage with the first groove 9. The first clips 8 slide relative to the first groove 9 along the edge of the inspection panel 1 where the first clips 8 are mounted. A connecting flange is provided on the mounting base 3, and the mounting side plates 2 are detachably connected to the connecting flange.

[0036] The access panel 1 is directionally and slidably engaged with the first slots 9 on a pair of mounting side plates 2 via multiple sets of first buckles 8 on both sides. When the access panel 1 moves along the edge extension direction of the mounting side plate 2, the first buckles 8 slide linearly within the first slots 9, enabling push-pull disassembly and assembly of the panel. The mounting side plates 2 are fixed to the connecting flange of the mounting base 3 via detachable connectors, forming a positioning structure that collectively constrains the spatial freedom of the access panel 1. During assembly, after the pair of mounting side plates 2 are installed in place on the mounting base 3, the first buckle is installed into the first slot 9, and then the access panel 1 is installed by sliding along the side of the access panel 1 with the first buckles 8. When the maintenance panel 1 is designed with a special shape with an irregular surface, the maintenance panel 1 can be installed by sliding a short distance after being aligned with the first buckle 8. The irregularly shaped maintenance panel 1 will not be limited by other structures during installation, which can ensure the stability of the connection of the installation structure, thereby ensuring the protective performance of the heat pump unit maintenance component housing for the internal maintenance components.

[0037] It should be noted that in this embodiment, the heat pump unit maintenance component housing is installed on one side of the heat pump unit. The heat pump unit housing includes a front injection-molded panel 5 and a rear finned mesh 6. A partition 7 is provided between the heat pump body and the maintenance component. Two mounting side plates 2 are fixedly connected to the partition 7. Specifically, a third latch 23 is provided on the side plate of the mounting side plate 2, and a third latch 24 is provided on the partition 7. The third latch 23 slides and engages with the third latch 23. The opening of the third latch 23 on the mounting side plate 2 faces downward, and the opening of the first latch 8 on the maintenance panel 1 faces upward. This creates a relative limit between the first latch 8 and the third latch 23 in the vertical direction, improving the overall stability of the housing. The heat pump unit and the maintenance component share a mounting cover 4, which together seals the top surfaces of the heat pump unit and the maintenance component.

[0038] In one embodiment, the side of the inspection panel 1 that mates with the mounting chassis 3 is provided with an arc-shaped flange 10. A bottom fixing plate 11 is fixedly installed between the arc-shaped flange 10 and the mounting chassis 3. A bottom flange 12 is provided on one side of the bottom fixing plate 11. The bottom fixing plate 11 and the bottom flange 12 respectively abut against the two outer edges of the arc-shaped flange 10, so that the bottom fixing plate 11 and the arc-shaped flange 10 form a closed cavity, which can effectively solve the problem that galvanized parts inside the housing are easily rusted when completely exposed to air. In this embodiment, the bottom flange 12 on the bottom fixing plate 11 is fixed to the upper side of the arc-shaped flange 10 by welding to further enhance the stability of the connection. At the same time, a surface protective paint is sprayed inside the closed cavity to enhance the rust prevention effect.

[0039] Furthermore, the bottom fixing plate 11 is fixedly connected to the mounting chassis 3 by fastening bolts, which serve as bottom fasteners. A recessed slot 13 is provided on the arc-shaped folded edge 10, facing the bottom fastener. External tools such as screwdrivers and wrenches can be inserted through the recessed slot 13 into the inside of the arc-shaped folded edge 10 to operate on the bottom fastener, for installation or removal. Simultaneously, the recessed slot 13 also serves as a channel for injecting surface protective paint, providing a spray nozzle for air-jet tools, facilitating the entry of surface protective paint into the cavity between the arc-shaped folded edge 10 and the bottom fixing plate 11, thus achieving rust prevention.

[0040] Specifically, the width of the bottom fixing plate 11 is smaller than the width of the arc-shaped fold 10, so that a clearance notch 14 is reserved on the side of the arc-shaped fold 10 facing the bottom fixing plate 11. A fixing fold 15 is provided at the bottom of the mounting side plate 2. The fixing fold 15 is fixedly connected to the mounting chassis 3 by fastening bolts, which are used as fixing fasteners. The fixing fold 15 is aligned with the clearance notch 14. This allows the bottom fasteners to extend into the clearance notch 14, tightly fixing the bottom fixing plate 11 to the mounting chassis 3, ensuring the stability of the connection between the bottom fixing plate 11 and the mounting side plate 2.

[0041] In this embodiment, to ensure the waterproof performance of the casing and prevent insects from entering the casing through the clearance notch 14, the fixed folded edge 15 completely covers the clearance notch 14. This effectively prevents external dust, moisture, and other foreign objects from entering the casing through the clearance notch 14, thereby improving the sealing performance and protection level of the equipment and extending its service life. It also prevents animals such as spiders, cockroaches, and geckos from entering the casing through the clearance notch 14, which could cause short circuits or corrosion. Furthermore, a sealing strip or waterproof membrane can be added to the contact area between the fixed folded edge 15 and the clearance notch 14 to further enhance the waterproof performance.

[0042] In one embodiment, a U-shaped water guide channel 16 is provided on the side of the mounting side plate 2. A first slot 9 is provided on the side wall of the water guide channel 16, and three first slots 9 are spaced apart along the extending direction of the water guide channel 16. Three first buckles 8 are correspondingly provided. By providing the water guide channel 16, water flowing into the edge of the mounting side plate 2 can be discharged along the water guide channel 16 under the action of gravity, preventing water from entering the housing through the first slots 9 and damaging the internal components. The cross-sectional shape of the water guide channel 16 can also be triangular or semi-circular, etc.

[0043] In one embodiment, both the access panel 1 and the mounting side panel 2 have 90° bent water-blocking edges 17 on their upper sides. When the access panel 1 and the mounting side panel 2 are assembled, they form a top waterproof barrier that can effectively block water from entering the housing and prevent rainwater or other liquids from penetrating into the housing from above. This improves the waterproof performance of the housing, protects the electrical components and other critical parts inside the housing, and reduces the risk of damage to internal components due to water ingress.

[0044] The heat pump unit maintenance assembly housing provided in this embodiment also includes a mounting cover plate 4. The mounting cover plate 4 has a second snap-fit ​​18 on its edge, and a second slot 19 is provided on the side of the mounting side plate 2 opposite to the mounting chassis 3. The second snap-fit ​​18 and the second slot 19 are slidably engaged. The second snap-fit ​​18 slides relative to the second slot 19 along the edge of the mounting cover plate 4 where the second snap-fit ​​18 is mounted. This allows the mounting cover plate 4 to be quickly installed onto the mounting side plate 2 through the slidable engagement of the second snap-fit ​​18 and the second slot 19, eliminating the need for additional fasteners, simplifying the installation process, and improving installation efficiency. Simultaneously, the sliding engagement structure ensures a tight connection between the mounting cover plate 4 and the mounting side plate 2, enhancing the overall integrity and stability of the housing.

[0045] Additionally, a connecting piece is provided on the side plate of the mounting cover 4. The connecting piece has only a fixing hole. After the second buckle 18 and the second slot 19 on the mounting cover 4 are slidably engaged, the fixing hole is aligned with the threaded mating hole on the injection-molded panel 5 or the finned guard 6. The mounting cover 4 is further fixed by threading the fastening bolt through the fixing hole and the threaded mating hole.

[0046] In one embodiment, the inspection panel 1 has a pre-drilled panel mounting opening 21, and a water-retaining folded edge 22 is provided on the lower side of the panel mounting opening 21. This prevents water from entering the inner cavity of the housing through the gaps along the edge of the wired controller, improving the waterproof performance of the housing and enhancing its reliability and durability in humid environments.

[0047] According to an embodiment of this utility model, another aspect provides a heat pump unit having the heat pump unit maintenance component housing provided in this embodiment. In this embodiment, the heat pump unit maintenance component housing is fixed using a screw and snap-fit ​​mechanism. On the two vertical sides of the mounting side plate 2, one side plate has a first slot 9, and the other side plate has a third snap-fit ​​23. The third snap-fit ​​23 snaps into the corresponding third slot 24 of the partition plate 7 from top to bottom. The fixing hole at the top of the mounting side plate 2 is used to fix it to the corresponding hole on the side of the electrical box with fastening screws. The fixing hole on the fixing flange 15 at the bottom of the mounting side plate 2 is used to fix it to the corresponding hole in the mounting base 3 with fastening screws, thereby completing the fixing of the mounting side plate 2. A pair of mounting side plates 2 have the same structure and are symmetrically arranged. The maintenance panel 1 is a push-pull snap-fit ​​from bottom to top, with three first snap-fits 8 on each of the left and right sides, corresponding to the three first slots 9 on the mounting side plate 2. After the first latch 8 is raised to its limit position, it is fixed to the chassis fixing hole through the fixing hole on the bottom fixing plate 11, thereby fixing the access panel 1 assembly. The travel of the first latch 8 on the access panel 1 and the first slot 9 on the mounting side plate 2 is as follows: the first slot 9 is 40mm long, and the first latch 8 is 28mm long in total; the insertion depth is 12mm, and the latch connection section is 16mm. Therefore, the access panel 1 can be disassembled when the downward movement distance is 12mm. When the access panel 1 is in the detachable state, the bottom folded edge 12 on the bottom fixing plate 11 will not be blocked by the screws on the corresponding fixing holes, thus allowing normal disassembly of the access panel 1. Two clearance slots 13 are provided on the bottom arc-shaped folded edge 10 of the access panel 1. A screwdriver can enter the inner side of the access panel 1 through the clearance slots 13 to disassemble and install the bolts between the bottom fixing plate 11 and the corresponding fixing holes. After the inspection panel 1 is welded to the bottom fixing plate 11 with bottom folded edge 12, there is a fan-shaped columnar cavity at the bottom. The galvanized sheet material is prone to rust when exposed to air. The clearance slot 13 also serves as a spray nozzle. Surface protective paint is sprayed into the fan-shaped columnar cavity through the clearance slot 13 to achieve the effect of rust prevention.

[0048] Three second buckles 18 and one connecting piece 20 are provided on each of the two sides of the mounting top cover. The connecting piece 20 has a fixing hole. The second buckles 18 are pushed from right to left into the second slots 19 on the top of the surrounding sheet metal parts by the heat pump unit housing. Then, they are fixed with screws through the fixing holes of the fin guard 6 and the fixing holes on the connecting piece to prevent loosening.

[0049] The top edges of the inspection panel 1 and the two mounting side plates 2 are all designed with water-retaining edges 17 to prevent water from entering the inner cavity of the housing through the gap between the top mounting cover. The mounting side plates 2, which mate with the inspection panel 1, have U-shaped water-guiding grooves 16. Corresponding folded edges on both sides of the inspection panel 1 extend into the U-shaped water-guiding grooves 16, forming a two-sided drainage and water-proof design. The first buckle 8 on the inspection panel 1 corresponds to the second buckle groove 19 located on the inner surface of the water-guiding groove 16, reducing the risk of water entering through the buckle holes. The bottom of the inspection panel 1 has an arc-shaped folded edge 10 with a clearance slot 13 for easy fixing, while the bottom folded edge 12 welded to the internal bottom fixing plate 11 effectively prevents splashing water. The water-retaining folded edge 22 on the lower side of the mounting opening 21 of the upper panel of the inspection panel 1, together with the water-retaining folded edge of the waterproof fixing plate of the wired controller 25, forms a closed cavity, preventing water from entering the press cavity through the gaps along the edge of the wired controller.

[0050] Insect-proof design is a crucial aspect of the long-term stable operation of heat pump units. It protects core components and improves energy efficiency, representing a low-cost, high-return preventative maintenance measure. Insect prevention measures within the compressor cavity of heat pump units are paramount for the following reasons: Spiders, cockroaches, geckos, and other insects can crawl into electrical junction boxes or control boards, causing short circuits or corrosion, leading to malfunctions or even component burnout. Decomposing insect carcasses can breed mold or corrode metal parts, accelerating wiring aging or contaminating the refrigeration system, especially in humid environments. Insect-proof design reduces the frequency of malfunctions caused by insects, lowering cleaning and maintenance costs. It also reduces fire hazards, as insect nests can cause wiring overheating, increasing the risk of fire, especially in high-voltage electrical areas.

[0051] The waterproof design on the top, left and right sides, and bottom of the inspection panel 1 simultaneously provides insect prevention. Regarding the bottom insect-proof isolation cavity design, the bottom of the inspection panel 1 features a rounded, curved edge 10. Conventional designs for snap-on inspection panels 1 include a downward-facing edge for screw holes, allowing for panel 1 assembly fixation. However, to ensure the bottom of the inspection panel 1 is flush with the mounting base, a recessed edge is designed around the bottom of the unit. In this embodiment, the inspection panel 1 assembly has an upward-facing curved edge 10 at the bottom, and a bottom fixing plate 11 with a bottom edge 12 is provided on the inner side of the inspection panel 1. The bottom fixing plate 11 is fixed to the mounting base using screws. A separate bottom fixing plate 11 is designed for insect prevention. Simultaneously, to avoid the fixing edges 15 on the left and right mounting side plates 2, a recessed groove 13 is provided at the bottom of the inspection panel 1. The mounting side plates 2 have fixing edges 15 at the bottom for fixation, with dimensions of 19×32×1mm (1mm being the plate thickness). This area must be avoided when designing the inspection panel 1. The bottom fixing plate 11 at the bottom of the inspection panel 1 has 19.1×32×2mm clearance notches on both the left and right sides to prevent interference between parts. After the inspection panel 1 is installed, this clearance notch area is completely sealed by the fixing folded edge 15 on the mounting side plate 2, thus preventing the fan-shaped columnar isolation area from communicating with the inside of the box, thereby avoiding the risk of insects entering due to the gaps in the two clearance slots 13.
