[0042] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0044] Secondly, it should be noted that in the description of this utility model, the terms "inner" and "outer," etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0045] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] The casing of the outdoor unit of a heat pump is a key component of the heat pump unit. Its main function is to provide protection and support for the internal core components such as the compressor, heat exchanger, and fan, while ensuring the stable operation of the heat pump unit in complex environments. With the widespread application of heat pump technology, users have increasingly higher requirements for the performance, durability, and appearance of heat pump outdoor units. The design of the casing needs to balance functionality and ease of installation and disassembly.

[0047] In existing technology, the top cover and side panels of the heat pump outdoor unit casing are typically connected by screws. Screw holes are provided at the connection edge between the top cover and the side panels, and screws are used for fixing during installation. This connection method ensures a tight fit between the top cover and the side panels, effectively preventing loosening or deformation due to vibration or external forces, while also providing strong load-bearing capacity and durability.

[0048] However, screw fastening not only increases the complexity and labor costs of installation and disassembly, but also raises material costs and is less efficient during maintenance and disassembly.

[0049] To address the aforementioned issues, this application provides a housing for a heat pump outdoor unit. By providing an inwardly folded first edge and a second edge on the top of the first and second side panels respectively, the top cover can directly engage with the folded edges of the side panels, achieving a secure connection without the need for additional fasteners. This structure enables a quick and secure engagement between the top cover and the side panels, simplifying the installation and disassembly process and thus improving installation and disassembly efficiency.

[0050] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0051] This application provides a housing for a heat pump outdoor unit, such as... Figure 1 As shown, the housing of a heat pump outdoor unit includes: a top cover 1, a first side plate 2, and a second side plate 3;

[0052] The top of the first side panel 2 has a first folded edge 5 that folds inward toward the inside of the first side panel 2;

[0053] The top of the second side panel 3 has a second folded edge 7 that folds inward toward the second side panel 3;

[0054] The top cover 1 is snapped to the first side plate 2 via the first folded edge 5, and the top cover 1 is snapped to the second side plate 3 via the second folded edge 7.

[0055] The casing structure of a heat pump outdoor unit mainly consists of a top cover 1, a first side plate 2 (such as the right side plate) and a second side plate 3 (such as the left side plate).

[0056] The top cover 1 is engaged with the first side panel 2 and the second side panel 3 through the cooperation of the folded edges and the buckles / slots. The first folded edge 5 and the second folded edge 7 can be designed with buckles or slots, and the corresponding positions of the top cover 1 are provided with matching engaging components.

[0057] For example, if the ends of the first folded edge 5 and the second folded edge 7 are provided with protruding buckles, then the corresponding positions of the top cover 1 need to be provided with buckle slots so that the buckles can be embedded in them to form a stable connection.

[0058] If the first fold 5 and the second fold 7 are changed to have slots, then the top cover 1 needs to be equipped with corresponding buckles so that the slots of the folds can be fastened to the buckles on the side panels.

[0059] This application provides a housing for a heat pump outdoor unit, comprising: a top cover 1, a first side plate 2, and a second side plate 3; the top of the first side plate 2 has a first folded edge 5 that folds inward toward the first side plate 2; the top of the second side plate 3 has a second folded edge 7 that folds inward toward the second side plate 3; the top cover 1 is snapped into the first side plate 2 via the first folded edge 5, and the top cover 1 is snapped into the second side plate 3 via the second folded edge 7. This structure enables the top cover 1 and the side plate to be snapped into place quickly and securely, simplifying the installation and disassembly process and thus improving the installation and disassembly efficiency.

[0060] like Figures 2-4 As shown, in this embodiment... Figure 1 Based on the previous embodiment, the scheme of providing a buckle for the top cover 1 and opening slots at corresponding positions of the first folded edge 5 and the second folded edge 7 is described in detail. The housing of the heat pump outdoor unit shown in this embodiment includes:

[0061] At least one buckle 4 is provided on each side of the top cover 1 near the first side plate 2 and the second side plate 3 facing downwards;

[0062] The first folded edge 5 is provided with at least one first slot 6 corresponding to the buckle 4;

[0063] The second folded edge 7 is provided with at least one second slot 8 corresponding to the buckle 4;

[0064] The top cover 1 is engaged with the first side plate 2 via buckle 4 and first slot 6, and the top cover 1 is engaged with the second side plate 3 via buckle 4 and second slot 8.

[0065] Understandably, the top cover 1 has at least one snap fastener 4 near each of its two side edges on its downward-facing side. These snap fasteners 4 are key to enabling quick assembly of the top cover 1 and the side panels. Meanwhile, the top of the first side panel 2 has an inwardly folded first folded edge 5, on which a first slot 6 corresponding to the snap fastener 4 on the top cover 1 is provided; the top of the second side panel 3 also has a similar inwardly folded second folded edge 7, equipped with a second slot 8 corresponding to the snap fastener 4 on the top cover 1. Thus, by cooperating with the snap fasteners 4 at the bottom of the top cover 1 and the slots on the top folded edges of the first side panel 2 and the second side panel 3, a stable connection between the top cover 1 and the two side panels is achieved.

[0066] Both side panels feature a 90-degree inward fold at the top, forming an L-shaped reinforcing edge to enhance the stability of the heat pump outdoor unit's casing structure. The folded edges of the first side panel 2 and the second side panel 3 respectively press out an open U-shaped first slot 6 and a second slot 8. The number and spacing of these slots match the buckles 4 on the top cover 1.

[0067] In one alternative implementation, such as Figure 3 and Figure 4As shown, the first folded edge 5 includes a first planar structure 9 and a first groove structure 10; the first planar structure 9 is parallel to the top cover 1, one side wall of the first groove structure 10 is connected to the first planar structure 9, the height of the bottom plane of the first groove structure 10 is lower than the height of the first planar structure 9, and the first slot 6 is located on the bottom plane of the first groove structure 10.

[0068] The second folded edge 7 includes a second planar structure 11 and a second groove structure 12; the second planar structure 11 is parallel to the top cover 1, one side wall of the second groove structure 12 is connected to the second planar structure 11, the height of the bottom plane of the second groove structure 12 is lower than the height of the second planar structure 11, and the second slot 8 is located on the bottom plane of the second groove structure 12.

[0069] The folded edge structure of the heat pump outdoor unit casing forms a robust snap-fit ​​system through the combination of a planar structure and a grooved structure. The top folded edge of the first side panel 2 is composed of a first planar structure 9 and a first grooved structure 10. The first planar structure 9 serves as the base of the folded edge and remains parallel to the top cover 1 to ensure structural integrity. The first grooved structure 10 is perpendicularly connected to the planar structure through its sidewall, forming an inward groove. Its bottom plane is approximately 2-3 mm lower than the first planar structure 9, creating a height difference. This height difference allows the first snap-fit ​​slot 6 to be embedded in the bottom of the grooved structure, protecting the edge of the slot from direct impact and providing a guide channel for the snap-fit ​​4 to slide in through the grooved sidewall.

[0070] The second side panel 3 features a symmetrical design with folded edges. The second planar structure 11 is parallel to the top cover 1, and the second grooved structure 12 forms a lower installation area than the planar surface in the same manner. This structure creates a standardized snap-fit ​​interface on both sides. When the top cover 1's snap fastener 4 slides in along the folded edge plane, the sidewall of the grooved structure acts as a guide, directing the snap fastener 4 accurately into the bottom slot. Since the slot is located at the lowest point of the grooved structure, after the top cover 1 is installed, the snap fastener 4 forms a surface contact with the bottom plane of the groove. Compared to a line contact slot, this increases the contact area, improving connection stability and vibration resistance.

[0071] In one alternative implementation, such as Figure 5 and Figure 6 As shown, the first slot 6 includes a first opening 13 and a second opening 14 that are connected. The width of the first opening 13 is smaller than the width of the second opening 14. One long side of the first opening 13 and one long side of the second opening 14 are on the same straight line and form the long side of the first slot 6. The long side of the first slot 6 is located on the side of the bottom plane of the first groove structure 10 that is close to the first planar structure 9.

[0072] The second slot 8 includes a connected third opening 15 and a fourth opening 16. The width of the third opening 15 is smaller than the width of the fourth opening 16. One long side of the third opening 15 and one long side of the fourth opening 16 are on the same straight line and form the long side of the second slot 8. The long side of the second slot 8 is located on the side of the bottom plane of the second groove structure 12 away from the second planar structure 11.

[0073] In the design of the heat pump outdoor unit casing, the structure of the first slot 6 and the second slot 8 achieves effective guidance and secure locking of the buckle 4 through a stepped opening design. First, let's look at the first slot 6 on the first side plate 2. It consists of a connected first opening 13 and a second opening 14. The first opening 13 is relatively narrow (e.g., 3-5mm). This width serves as an initial guide channel when the buckle 4 is inserted, ensuring that the buckle 4 can accurately enter the slot. The connecting second opening 14, however, has a larger width (e.g., 6-8mm) to provide sufficient depth for the buckle 4 to fully engage. This stepped width design not only helps reduce the difficulty of positioning during assembly but also improves the strength and stability of the connection due to the increased contact area. One long side of the first opening 13 and one long side of the second opening 14 are on the same straight line and together form the long side of the first slot 6. The position of this long side is close to the side of the bottom plane of the first groove structure 10 that is close to the first planar structure 9. This layout utilizes the rigidity of the side plate body to enhance the deformation resistance of the slot and avoid the problem of slot expansion in long-term use or vibration environment.

[0074] For the second side plate 3, the second slot 8 adopts a similar stepped opening design, including a third opening 15 and a fourth opening 16. The third opening 15 is also a narrow opening to guide the buckle 4 smoothly into place, while the fourth opening 16 is a wide opening, providing the buckle 4 with a final stable engagement space. Unlike the first slot 6, the long side of the second slot 8 is located on the side of the bottom plane of the second groove structure 12 away from the second planar structure 11. On the second side plate 3, the slot design is more inclined to protect the slot from external factors, while utilizing the physical properties of the side plate itself to increase the overall structural rigidity. In addition, the long sides of the third opening 15 and the fourth opening 16 are collinear, ensuring that the buckle 4 smoothly transitions from the narrow guide channel to the wider engagement area, achieving a smooth and secure connection.

[0075] In one alternative implementation, the buckle 4 that engages the top cover 1 with the first side plate 2 engages with the second opening 14, and the buckle 4 that engages the top cover 1 with the second side plate 3 engages with the fourth opening 16, the lengths of the second opening 14 and the fourth opening 16 matching the buckle 4.

[0076] The snap-fit ​​system of the heat pump outdoor unit casing achieves a highly efficient and stable connection structure by matching the snap-fit ​​4 with the stepped opening design. During assembly, the snap-fit ​​4 on both sides of the top cover 1 engages with the second opening 14 of the first side plate 2 and the fourth opening 16 of the second side plate 3, respectively.

[0077] The buckle 4 of the top cover 1 facing the first side plate 2 has its hook-like structure fully engaged with the second opening 14 of the first slot 6. This opening serves as the wide section of the slot, and its length matches the lateral dimension of the buckle 4. The long inner side of the opening is in contact with the base of the buckle 4, and the width of the second opening 14 is slightly larger than the maximum outer diameter of the hook of the buckle 4, ensuring that the buckle 4 can slide in smoothly. The second opening 14 is close to the first plane, keeping the long side of the slot at the shortest distance from the main body of the side plate, effectively reducing stress concentration in the cantilever section of the folded edge, and improving the connection reliability under long-term vibration environment.

[0078] The buckle 4 on the other side of the top cover 1 engages with the fourth opening 16 of the second side plate 3. The fourth opening 16 serves as the wide section of the second slot 8, and its length also matches the corresponding buckle 4, but the layout direction is opposite. This opening is located on the side of the bottom plane of the second groove structure 12 away from the second planar structure 11.

[0079] In one alternative implementation, such as Figure 3 and Figure 4 As shown, one side of the first side plate 2 has a third folded edge 17 that folds inward toward the first side plate 2, and the top of the third folded edge 17 has a fourth folded edge 18 that folds inward toward the third folded edge 17, and the edge of the fourth folded edge 18 folds downward.

[0080] One side of the second side panel 3 has a fifth fold 19 that folds inward toward the second side panel 3, and the top of the fifth fold 19 has a sixth fold 20 that folds inward toward the fifth fold 19, with the edge of the sixth fold 20 folded downward.

[0081] For the first side panel 2, one side is designed as a third folded edge 17 that folds inward. This third folded edge 17 not only increases the structural strength of the side panel but may also facilitate subsequent assembly or fixing. At the top of the third folded edge 17, a fourth folded edge 18 is designed, and this double-layered folded edge structure further enhances stability. The edge of the fourth folded edge 18 is also folded downward; this detail is likely for a better fit with the top cover 1, ensuring the stability and sealing of the entire structure.

[0082] As for the second side panel 3, its structure is similar to but independent of the first side panel 2. One side of the second side panel 3 also has a fifth folded edge 19 that folds inward. The function of this folded edge is similar to that of the third folded edge 17, both serving to enhance the stability of the side panel and facilitate assembly. At the top of the fifth folded edge 19, a sixth folded edge 20 is also designed, forming a similar double-layered folded edge structure. The edge of the sixth folded edge 20 is also folded downward, a design also intended to achieve a better fit with the top cover 1.

[0083] The folded edge structure of the first side plate 2 and the second side plate 3, through the design of multi-layer folding and edge flipping, not only enhances the stability and structural strength of the side plates, but also provides more possibilities and convenience for subsequent assembly and fixing.

[0084] In one alternative implementation, such as Figures 2-4 , Figure 7 as well as Figure 8 As shown, the casing of the heat pump outdoor unit also includes a back plate 21;

[0085] The top cover 1 has an eighth fold edge 22 that folds inward toward the back panel 21 on one side, the first side panel 2 has a ninth fold edge 23 that folds inward toward the first side panel 2 on the other side, and the second side panel 3 has a tenth fold edge 24 that folds inward toward the second side panel 3 on the other side.

[0086] The eighth fold 22 has at least two openings 25, and the ninth fold 23 and the tenth fold 24 each have openings 25 corresponding to the positions of the openings 25 on the eighth fold 22.

[0087] The top cover 1 is screwed to the first side plate 2 and the second side plate 3 through the opening 25.

[0088] First, the waterproof structure of the heat pump unit's electrical control box includes a back plate 21, which serves as a support for fixing and connecting the first side plate 2, the second side plate 3, and the top cover 1. The top cover 1 has an eighth folded edge 22 that folds inward on the side closest to the back plate 21. This folding design not only enhances the strength of the top cover 1 but also facilitates its connection with the side plates.

[0089] Next, the other sides of the first side panel 2 and the second side panel 3 are also designed with inwardly folded ninth fold edge 23 and tenth fold edge 24, respectively. These folded edge designs make the connection between the side panels and the top cover 1 more secure. To further secure these components, at least two openings 25 are provided on the eighth fold edge 22, while the ninth fold edge 23 and the tenth fold edge 24 are also provided with openings 25 corresponding to the positions of the openings 25 on the eighth fold edge 22. The corresponding design of these openings 25 ensures that the top cover 1 and the two side panels can be tightly connected by screws.

[0090] Finally, the top cover 1 is screwed to the first side plate 2 and the second side plate 3 through the opening 25. This screwing method not only facilitates installation and disassembly but also ensures the stability and robustness of the entire structure. The overall design, through the combination of the folded edges and the opening 25, achieves an efficient connection between the top cover 1 and the side plates, while enhancing the overall strength of the structure.

[0091] In one alternative implementation, such as Figure 9 As shown, the top cover 1 has at least one reinforcing rib 26 on the downward-facing side, and the reinforcing rib 26 is arranged in a direction perpendicular to the first side plate 2 and the second side plate 3.

[0092] At least one reinforcing rib 26 is provided on the downward-facing side of the top cover 1. The main function of these reinforcing ribs 26 is to enhance the structural strength of the top cover 1 and prevent it from deforming or being damaged during use. The reinforcing ribs 26 are arranged perpendicular to the first side plate 2 and the second side plate 3. This design can effectively distribute the force borne by the top cover 1 and further improve the stability and durability of the overall structure.

[0093] By arranging the reinforcing ribs 26 perpendicular to the side plates, the top cover 1 can better resist bending or torsion when subjected to external forces. This design not only optimizes the mechanical properties of the top cover 1 but also allows for a more even distribution of pressure across the entire structural component under load, thereby extending its service life. The presence of the reinforcing ribs 26 is a common reinforcement method in structural design, which can significantly improve the strength and rigidity of components without significantly increasing weight.

[0094] In one alternative implementation, such as Figure 9 and Figure 10 As shown, the casing of the heat pump outdoor unit also includes a front panel 27;

[0095] The top cover 1 has a seventh fold edge 28 on the side near the front panel 27. The seventh fold edge 28 includes a folded edge 29 formed by folding it inward to the top cover 1, and a limiting fold edge formed by folding the edge of the folded edge 29 downward and then folding it inward to the front panel 27. The portion of the limiting fold edge that is folded inward to the front panel 27 is inclined downward.

[0096] The top cover 1 has overlapping edges 29 on both sides near the first side plate 2 and the second side plate 3.

[0097] In addition to components such as the top cover 1 and the back panel 21, the housing also includes a front panel 27. The top cover 1 has a seventh fold edge 28 on the side near the front panel 27. This fold edge adopts a multi-layer folding structure to achieve a stable connection and limiting function with the front panel 27.

[0098] Understandably, the seventh fold edge 28 first folds inward towards the top cover 1 to form a folded edge 29, a design that enhances the strength of the top cover 1's edge. Next, the edge of the folded edge 29 folds further downward, and then folds towards the front panel 27 to form a limiting fold edge. The function of the limiting fold edge is to ensure the accurate connection between the top cover 1 and the front panel 27, while preventing the top cover 1 from shifting or loosening during use. Furthermore, the portion of the limiting fold edge that folds towards the front panel 27 is designed to slope downwards. This sloped structure not only facilitates installation and disassembly but also effectively prevents dust or debris from entering the connection gaps, improving the sealing and durability of the housing.

[0099] The top cover 1 has overlapping edges 29 on both sides near the first side plate 2 and the second side plate 3. This overlapping edge 29 structure is formed by folding the edge of the top cover 1 inward, and its main function is to enhance the strength and stability of the edge of the top cover 1. Through the overlapping edge 29 design, the connection between the top cover 1 and the side plate can better withstand external forces and reduce the risk of deformation or damage.

[0100] The presence of the overlapping edge 29 not only improves the structural rigidity of the top cover 1, but also provides a larger contact area for the connection between the top cover 1 and the side panel, making the connection between the two more robust. This design is common in housing products and can effectively improve the overall structural durability and reliability. In addition, the overlapping edge 29 can also play a certain sealing role, preventing dust or moisture from entering the housing and further protecting the internal components.

[0101] The installation process of the top cover 1 is as follows: First, the top cover 1 is aligned with the groove structure of the first side plate 2 and the second side plate 3 near the back panel 21. The buckle 4 of the top cover 1 is aligned with the first slot 6 and the second slot 8 of the side plate, ready to enter the groove structure. The buckle 4 of the top cover 1 is inserted into the groove structure from the first opening 13 and the third opening 15. Since the width of the first opening 13 and the third opening 15 is small, the buckle 4 can be initially limited to ensure that the buckle 4 accurately enters the groove structure. Next, after the buckle 4 enters the groove structure, it slides towards the front panel 27 along the long side of the first slot 6 and the second slot 8. During the sliding process, the buckle 4 gradually moves from the first opening 13 and the third opening 15 to the second opening 14 and the fourth opening 16. When the buckle 4 slides to the second opening 14 and the fourth opening 16, since the width of the second opening 14 and the fourth opening 16 is large, the buckle 4 is fully accommodated and fixed in that position. The lengths of the second opening 14 and the fourth opening 16 match the buckle 4, ensuring that the buckle 4 will not wobble or shift within the groove structure. After the top cover 1 slides into place, the buckle 4 forms a stable connection with the second opening 14 and the fourth opening 16. Then, the top cover 1 is screwed to the first side plate 2 and the second side plate 3 through the opening 25. At this time, the top cover 1 is fixed to the first side plate 2 and the second side plate 3 through a snap-fit ​​and screw-fit engagement.

[0102] This application provides a heat pump unit, including a housing as described above and a heat exchange assembly disposed within the housing.

[0103] A basic structure of a heat pump unit mainly includes two parts: a shell and heat exchange components. The shell adopts the aforementioned design and includes components such as a top cover 1, a front panel 27, a first side panel 2, a second side panel 3, and a back panel 21. The shell design achieves a stable connection between the components through overlapping edges, folded edges, and openings, while enhancing the overall structural strength and sealing, effectively protecting the internal components from the influence of the external environment.

[0104] The heat exchanger is the core component of a heat pump unit, housed within the casing. It typically includes components such as an evaporator, condenser, and compressor, used to absorb, transfer, and release heat. The performance of the heat exchanger directly determines the efficiency and stability of the heat pump unit. By installing the heat exchanger within the designed casing, not only is a favorable operating environment provided, but external interference with the heat exchange process is also reduced, thereby improving the overall performance of the heat pump unit.
