[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] In related technologies, current heat pump standby systems generally adopt a modular enclosure structure. Air ducts, functional components, refrigerant circulation loops, and water piping are all integrated within this enclosure, saving installation space and improving equipment compactness. To facilitate maintenance of the enclosure's interior, the panel and shell are typically detachably connected; specifically, the edges of the panel on both sides are connected to the corresponding leading edges of the side panels.

[0045] However, due to factors such as equipment operating vibration, airflow pressure, thermal stress, and material recovery force, the central area of ​​the panel is prone to forward bulging deformation due to the lack of effective support. This not only creates gaps between the panel and the shell, reducing the airtightness of the heat pump equipment and thus affecting its heat exchange performance and efficiency, but also leads to a decrease in the flatness of the heat pump equipment's appearance.

[0046] Some heat pump products use multi-point bolt fixing to enhance the stability of the panel connection. However, this solution not only disrupts the uniformity of the equipment's appearance but also increases the risk of gas leakage and condensation in the heat pump equipment.

[0047] To address the aforementioned technical problems, some embodiments of this utility model propose a housing assembly 1000 that can prevent the central area of ​​the panel 200 from bulging and deforming forward. This assembly is suitable for heat pump equipment. See details below. Figures 1 to 11 The enclosure assembly 1000 is described as shown.

[0048] Reference Figure 1 and Figure 2As shown, in this embodiment of the present invention, the housing assembly 1000 includes a shell 100 and a panel 200, which, when connected, form a box-like structure, thus serving as the outer shell of a heat pump device. The box-like structure has an internal cavity where functional components such as a fan 300, a compressor (not shown), and a heat exchanger can be installed. In this embodiment, for the inspection and maintenance of components within the internal cavity, a mounting port 121 is provided on the front side of the shell 100. The mounting port 121 communicates with the internal cavity, and the panel 200 is detachably covered at the mounting port 121 to seal the box-like structure.

[0049] Specifically, in this embodiment of the invention, the two sides of the panel 200 are respectively connected to the corresponding two sides of the housing 100. For example, the panel 200 and the housing 100 are arranged sequentially along the front-back direction, wherein the left and right sides of the panel 200 are respectively connected to the left and right sides of the housing 100. Specifically, the panel 200 is provided with connecting portions 230 on both sides along the first direction, and the connecting portions 230 are detachably connected to the housing 100. In some embodiments, the connecting portions 230 and the housing 100 can be connected by structures such as buckles, screws, or locks, which is not limited in this embodiment.

[0050] Continue to refer to Figure 1 and Figure 2 As shown, in this embodiment of the present invention, the panel 200 has a first limiting portion 210 on at least one side along a second direction, wherein the second direction is perpendicular to the first direction. It should be noted that in this embodiment, the first direction can be the left-right direction of the housing assembly 1000, and the second direction can be the front-back direction of the housing assembly 1000. Specifically, the panel 200 has a first limiting portion 210 on its end face (i.e., rear side) facing the housing 100, and correspondingly, a second limiting portion 110 is provided on the front side of the housing 100 at a position corresponding to the first limiting portion 210. The first limiting portion 210 and the second limiting portion 110 engage. Specifically, when assembling the panel 200, one side of the panel 200 is first aligned with the housing 100, then the first limiting portion 210 and the second limiting portion 110 are engaged, and the other side of the panel 200 is connected to the housing 100, thereby completing the assembly of the housing assembly 1000.

[0051] Combination Figure 2 It is understood that in this embodiment of the present invention, the first limiting part 210 is disposed near the middle part of the panel 200. Specifically, the first limiting part 210 is spaced apart from the connecting parts 230 provided on both sides of the panel 200 and is located between the two connecting parts 230. The middle part can be understood as dividing the width of the panel 200 into three equal parts from left to right, with the leftmost part being the left part, the rightmost part being the right part, and the part between the left and right parts being the middle part.

[0052] Obviously, by providing a first limiting part 210 near the center of the panel 200 and a second limiting part 110 at the corresponding position on the housing 100, the position of the panel 200 near its center area is connected to the housing 100, thus constraining the center area of ​​the panel 200 and preventing the center area of ​​the panel 200 from bulging and deforming forward. On the one hand, this can avoid gaps between the panel 200 and the housing 100 due to bulging and deformation, thereby ensuring the overall airtightness of the housing assembly 1000. On the other hand, it can ensure the flat appearance of the housing assembly 1000 and enhance its aesthetics.

[0053] Reference Figure 1 As shown, in this embodiment of the present invention, the housing 100 includes a chassis 130, a top cover assembly 150, and a side plate 120. The side plate 120 extends circumferentially along the housing assembly 1000, forming a U-shaped structure. Specifically, the chassis 130 is connected to the lower end of the side plate 120, and the top cover is installed on the upper end of the side plate 120. In this embodiment, the side plate 120, chassis 130, and top cover assembly 150 cooperate to form an installation opening 121, and the front edges of both sides of the side plate 120 are respectively connected to the two sides of the panel 200.

[0054] Combination Figure 2 It is understood that, in this embodiment of the present invention, the first limiting part 210 may be disposed at the upper end of the panel 200, at the lower end of the panel 200, or at both the upper and lower ends of the panel 200. In one example, the upper and lower ends of the panel 200 are both provided with the first limiting part 210, and correspondingly, the upper and lower ends of the housing 100 are provided with the second limiting part 110.

[0055] For ease of description, the following explanation will use an example where the panel 200 has a first limiting part 210 at both the upper and lower ends. (Refer to...) Figure 3 and Figure 4 As shown, in this embodiment of the present invention, the top cover assembly 150 includes a bracket 140, and the second limiting part 110 includes a first buckle 111, which is disposed in the middle of the front side of the bracket 140. Correspondingly, the first limiting part 210 includes a first spring buckle 211, which is disposed in the upper middle of the rear end face of the panel 200.

[0056] Reference Figure 5 and Figure 6As shown, in this embodiment of the present invention, the second limiting part 110 further includes a second latch 112, which is disposed in the middle of the front side of the chassis 130. Correspondingly, the first limiting part 210 further includes a second spring latch 212, which is disposed in the lower middle of the rear end face of the panel 200. When assembling the housing assembly 1000, the left and right sides of the panel 200 are respectively connected to the sides of the side plate 120, the upper end of the middle part of the panel 200 is connected to the bracket 140, and the lower end of the middle part of the panel 200 is connected to the chassis 130. This not only prevents the upper or lower end of the middle part of the panel 200 from bulging and deforming, but also improves the overall structural stability of the housing assembly 1000.

[0057] Reference Figure 2 As shown, in this embodiment of the present invention, the panel 200 includes a main body 220 and two connecting portions 230, wherein the two connecting portions 230 are respectively formed on the left and right sides of the main body 220. Specifically, the two sides of the main body 220 are bent and extended toward the rearward side, thereby forming connecting portions 230 protruding from the main body 220. In this embodiment, the first spring buckle 211 is disposed at the upper end of the rear end face of the main body 220, and the second spring buckle 212 is disposed at the lower end of the rear end face of the main body 220.

[0058] Reference Figure 7 As shown in this embodiment of the invention, when the panel 200 is connected to the housing 100, two connecting portions 230 are connected to the two sides of the side plate 120 in a one-to-one correspondence, and the outer wall surface of the connecting portion 230 is flush with the outer wall surface of the side plate 120. It should be noted that the outer wall surface referred to here refers to the end face of the connecting portion 230 and the side plate 120 that faces away from the inner cavity. It can be understood that the flushness of the outer wall surface of the connecting portion 230 and the outer wall surface of the side plate 120 can avoid a stepped difference at the connection point, improve the integrated design of the housing assembly 1000, and also disperse stress, thereby improving the structural stability of the housing assembly 1000.

[0059] Reference Figure 2 As shown in this embodiment of the invention, an overlapping portion 221 is provided at the upper end of the rear end face of the main body 220. The overlapping portion 221 protrudes from the rear end face of the main body 220 and extends from front to back. When assembling the panel 200, the panel 200 needs to be pushed into the mounting opening 121 from front to back. At this time, the overlapping portion 221 cooperates with the bracket 140, playing a positioning and guiding role. After the panel 200 is assembled, the overlapping portion 221 overlaps the upper end of the bracket 140. On the one hand, it can disperse stress and reduce the stress on the fixed connection between the panel 200 and the housing 100; on the other hand, the overlapping portion 221 fits against the upper end face of the bracket 140, improving the connection stability between the panel 200 and the housing 100.

[0060] Reference Figure 4 and Figure 6As shown, in this embodiment of the present invention, the first snap fastener 211 is formed on the surface of the overlapping portion 221, and the second snap fastener 212 is formed on the rear surface of the main body 220. It is understood that in this embodiment, the first snap fastener 211 and the second snap fastener 212 are integrally formed with the main body 220. Based on this, the root of the first snap fastener 211 can be formed in the overlapping portion 221, forming a gradually changing thickness transition area between the root of the first snap fastener 211 and the overlapping portion 221. However, the root of the second snap fastener 212 can only be formed on the end face of the main body 220. Due to the structural constraints of the main body 220, the root thickness of the second snap fastener 212 is relatively small. Therefore, in this embodiment, the sidewall of the second snap fastener 212 can be provided with reinforcing ribs connected to the main body 220, thereby improving the strength and stability of the second snap fastener 212.

[0061] In this embodiment of the utility model, the heat exchanger includes an evaporator 400 and a plate heat exchanger (not shown in the figure), wherein, referring to Figure 1 As shown, in this embodiment, the evaporator 400 is located in the middle of the inner cavity and is arranged vertically along the height direction of the housing assembly 1000. The evaporator 400 divides the inner cavity into an air inlet chamber and an air outlet chamber. The air inlet chamber is located on the right side of the evaporator 400, and the air outlet chamber is located on the left side of the evaporator 400. The compressor and plate heat exchanger are located in the air inlet chamber, and the fan 300 is located in the air outlet chamber.

[0062] Therefore, to avoid interference between the second latch 112 and the evaporator 400, refer to Figure 5 and Figure 8 As shown, in this embodiment of the present invention, the second limiting part 110 includes at least two second fastening positions 112. For example, there may be two, three, four, or five second fastening positions 112, etc., and this embodiment does not limit this. For ease of description, the following description uses two second fastening positions 112 as an example. In this embodiment, the two second fastening positions 112 are arranged at intervals along the second direction. Correspondingly, there are also two second spring-loaded buckles 212, which are arranged at intervals along the second direction.

[0063] Understandably, the space between the two second spring clips 212 can define a space suitable for accommodating the evaporator 400, thereby separating the second latch 112 from the evaporator 400 and preventing interference between the connection between the panel 200 and the base and the evaporator 400. It should be noted that the overlapping part 221 is located on the upper side of the evaporator 400; therefore, the setting of the first spring clip 211 and the first latch 111 is not affected by the evaporator 400.

[0064] Reference Figure 8As shown, in this embodiment of the invention, the two second fasteners 112 are located on both sides of the evaporator 400, thereby ensuring the force balance in the central area of ​​the panel 200. Further, in this embodiment, along the first direction, the maximum width of the housing assembly 1000 is L, and the minimum distance between the second fastener 112 and the centerline 122 of the side panel 120 is X, satisfying: X≤L / 4.

[0065] It is understood that this embodiment constrains the distribution area of ​​the second buckle 112 by reasonably limiting X, thereby preventing the second buckle 112 from being too close to the two side edges of the housing 100, preventing the connection point between the panel 200 and the housing 100 from being far away from the central area of ​​the panel 200, and thus preventing the central area of ​​the panel 200 from continuing to bulge due to loss of constraint, thereby enhancing the reliability of the engagement between the second buckle 112 and the second spring buckle 212.

[0066] refer to Figure 9 As shown in the embodiment of this utility model, the first spring buckle 211 and the second spring buckle 212 have the same structure, specifically, both include a first spring piece 2111 and a second spring piece 2112. Specifically, the first spring buckle 211 and the second spring buckle 212 are spaced apart in the left-right direction, and a limiting groove 2113 is formed between them, with the opening of the limiting groove 2113 facing rearward. Correspondingly, the first buckle position 111 and the second buckle position 112 also have the same structure, both being constructed as columnar limiting posts 1111.

[0067] Understandably, continue to refer to Figure 9 As shown, in this embodiment of the invention, the first spring piece 2111 and the second spring piece 2112 are elastic elements, capable of shifting towards or away from each other. In this embodiment, in their natural state, the width of the limiting groove 2113 is W, and the limiting post 1111 is cylindrical with a maximum outer diameter of d, satisfying d > W. Based on this, when the panel 200 is pushed into the mounting opening 121 from front to back, the limiting post 1111 presses against the first spring piece 2111 and the second spring piece 2112, causing them to shift away from each other, thus increasing the opening of the limiting groove 2113, allowing the limiting post 1111 to enter the limiting groove 2113. After the limiting post 1111 enters, the first spring piece 2111 and the second spring piece 2112, no longer compressed, return to their original positions, confining the limiting post 1111 within them, thereby achieving the engagement between the limiting groove 2113 and the limiting post 1111.

[0068] Continue to refer to Figure 9As shown, in this embodiment of the present invention, the limiting groove 2113 includes a snap-fit ​​section 2114 and a guide section 2115, which are interconnected. The guide section 2115 and the snap-fit ​​section 2114 are arranged sequentially from front to back. In this embodiment, the opening of the guide section 2115 gradually increases from front to back. Specifically, the middle part of the first spring piece 2111 protrudes towards the second spring piece 2112, and the middle part of the second spring piece 2112 protrudes towards the first spring piece 2111. Based on this, the guide section 2115 can guide the limiting post 1111 into the snap-fit ​​section 2114, playing a guiding role, thereby increasing the fault tolerance of the panel 200 assembly. The snap-fit ​​section 2114 is used to snap with the limiting post 1111, thereby restricting the limiting post 1111 from disengaging.

[0069] refer to Figure 10 and Figure 11 As shown, in this embodiment of the present invention, the height of the limiting post 1111 along the height direction of the housing assembly 1000 is H1, and the height of the first spring piece 2111 and the second spring piece 2112 along the height direction of the housing assembly 1000 is H2, satisfying: H1 > H2. It can be understood that the limiting post 1111 being higher than the first spring piece 2111 and the second spring piece 2112 not only ensures that the limiting post 1111 can be completely embedded in the coverage area of ​​the first spring piece 2111 and the second spring piece 2112, avoiding the locking point being suspended, but also uses the portion of the limiting post 1111 extending beyond the first spring piece 2111 and the second spring piece 2112 as redundancy, reducing the risk of the limiting post 1111 disengaging from the limiting groove 2113.

[0070] Understandably, the inventors, through numerous experiments, discovered that if the minimum thickness of the first spring piece 2111 and the second spring piece 2112 along the width direction of the panel 200 is too large, the first spring piece 2111 and the second spring piece 2112 will lose their elasticity, making it difficult for the limiting post 1111 to enter the limiting groove 2113; conversely, if the minimum thickness of the first spring piece 2111 and the second spring piece 2112 along the width direction of the panel 200 is too small, the strength of the first spring piece 2111 and the second spring piece 2112 will be weak, increasing the possibility of their damage. Therefore, referring to... Figure 9 As shown, in this embodiment of the present invention, the minimum thickness of the first spring piece 2111 and the second spring piece 2112 along the first direction is T, which satisfies: 1.5mm≤T≤2.5mm.

[0071] Understandably, by reasonably limiting T, not only are sufficient deformation capabilities of the first spring clip 211 and the second spring clip 212 ensured to facilitate the entry of the limiting post 1111, but also the first spring clip 211 and the second spring clip 212 are able to securely restrict the limiting post 1111 within the limiting groove 2113, thereby improving the connection stability between the panel 200 and the housing 100, but also the first spring clip 211 and the second spring clip 212 are ensured to have sufficient strength to avoid damage.

[0072] This utility model also provides a heat pump device, including the housing assembly 1000 described in the above embodiments. Specifically, the heat pump device can be a heat pump water heater or a heat pump heating system; this embodiment does not limit this.

[0073] The heat pump device of this utility model embodiment adopts the housing assembly 1000 of the above embodiment.
