[0004] In related technologies, heat pump equipment is typically installed indoors, utilizing outdoor air as a heat source to extract heat through a series of heat exchange processes, thereby providing hot water or indoor heating.

Detailed Implementation
[0053] The embodiments of this application 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 application, and should not be construed as limiting this application.
[0054] In the description of this application, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.
[0055] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.
[0056] In the description of this application, unless otherwise expressly defined, terms such as "setup," "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 application in conjunction with the specific content of the technical solution.
[0057] Heat pump equipment, as a highly efficient and energy-saving heating device, is widely used in hot water supply and indoor heating systems. Heat pump equipment is typically installed indoors, and its main working principle is to utilize outdoor air as a heat source, extracting heat through a series of heat exchange processes to heat hot water or provide indoor heating. Specifically, heat pump equipment can effectively capture heat from the intake air and use that heat to heat water or directly for indoor heating.
[0058] However, when the air inside the heat pump unit is maintained at a low temperature range (e.g., 0°C to -20°C), while the indoor environment is relatively warm, the temperature of the heat pump unit's outer casing exposed to the indoor environment is also relatively high. When the cold air inside the heat pump unit comes into contact with the warm outer casing, condensation easily forms on the outer surface of the casing due to the significant temperature difference. The formation of condensation can not only accelerate the corrosion process of the heat pump unit's casing and shorten its lifespan, but it can also have adverse effects on the indoor environment, such as causing slippery floors and promoting the growth of mold and bacteria.
[0059] Therefore, some embodiments of this application propose a housing assembly 1000 suitable for a heat pump device 2000. For example, the heat pump device 2000 may be a heat pump water heater. The housing assembly 1000 is described in detail with reference to Figures 1 to 21.
[0060] For ease of description, the following description will use the case assembly 1000 applied to a heat pump device 2000 having a first heat exchanger 201, a second heat exchanger 202, a compressor 203, and a fan 204 as an example. Referring to Figures 1 and 2, in an embodiment of this application, the case assembly 1000 includes: a chassis structure 100, side plates 200, and a top cover 300, wherein the side plates 200 are arranged circumferentially along the chassis structure 100, and one end of the side plates 200 is connected to the outer periphery of the chassis structure 100. The top cover 300 is connected to the other end of the side plates 200. Based on this, the chassis structure 100, side plates 200, and top cover 300 together enclose the inner cavity 101 of the heat pump device 2000, while the chassis structure 100, side plates 200, and top cover 300 serve as the outer shell of the heat pump device 2000. It should be noted that the chassis structure 100, side plate 200 and top cover 300 can be detachably connected. For example, the chassis structure 100, side plate 200 and top cover 300 can be connected by fasteners or by snap-fit connections, etc. This embodiment does not limit this.
[0061] Referring again to Figures 1 and 2, in the embodiments of this application, a heat pump device 2000 comprising a first heat exchanger 201, a second heat exchanger 202, a compressor 203, and a fan 204 is disposed in an inner cavity 101. The first heat exchanger 201 is located in the middle of the inner cavity 101 and can divide the inner cavity 101 into an air inlet cavity 102 and an air outlet cavity 103. Correspondingly, the top cover 300 is provided with an air inlet 310 communicating with the air inlet cavity 102 and an air outlet 320 communicating with the air outlet cavity 103.
[0062] In one example, the air inlet 310 and the air outlet 320 are connected to the outdoor environment via pipes. Outdoor cold air enters the air inlet chamber 102 through the air inlet 310, then flows through the first heat exchanger 201 for heat exchange, before entering the air outlet chamber 103 and finally returning to the outdoor environment through the air outlet 320. The second heat exchanger 202 and the compressor 203 are located in the air inlet chamber 102, while the fan 204 is located in the air outlet chamber 103.
[0063] In the embodiments of this application, the first heat exchanger 201 is an evaporator, and the second heat exchanger 202 is a plate heat exchanger, which is connected to the water flow path. Based on this, during heating, the compressor 203 compresses the refrigerant, increasing its temperature and pressure; subsequently, the high-temperature, high-pressure refrigerant is sent to the second heat exchanger 202 and releases heat into the water flow path to heat the water; the refrigerant, after releasing heat, enters the first heat exchanger 201 and exchanges heat with the cold air in the inner cavity 101, thereby absorbing heat and preparing for the next cycle.
[0064] Understandably, to prevent the cold air in the inner cavity 101 from coming into contact with the relatively high-temperature indoor environment and thus generating condensation, as can be seen from Figure 2, in this embodiment of the application, the chassis structure 100, side panels 200, and top cover 300 are each provided with an insulation layer 400. For example, in this embodiment, the insulation layer 400 is a foam component, which can be foamed and molded according to the specific shape and size of the chassis structure 100, side panels 200, and top cover 300, thereby ensuring that each foam component can match its corresponding part.
[0065] In one example, the underside of the chassis structure 100 is covered with an insulation layer 400, the outer side of the side panel 200 is covered with an insulation layer 400, the insulation layer 400 extends circumferentially along the side panel 200, and the upper side of the top cover 300 is covered with an insulation layer 400. It is understood that in this embodiment, the insulation layer 400 is disposed on the outer side of the heat pump device 2000's casing, forming a thermal barrier that isolates the casing from the indoor environment. Therefore, the temperature of the chassis structure 100, side panel 200, and top cover 300 will not rise with the higher indoor temperature, preventing the casing from being simultaneously affected by two air types with significant temperature differences. Even if the cold air in the inner cavity 101 comes into contact with the chassis structure 100, side panel 200, and top cover 300, condensation is unlikely to occur, thereby reducing the possibility of condensation on the outer surface of the casing.
[0066] Referring to Figure 2, in another example, the upper side of the chassis structure 100 is covered with an insulation layer 400, the inner side of the side plate 200 is covered with an insulation layer 400, the insulation layer 400 extends circumferentially along the side plate 200, and the lower side of the top cover 300 is covered with an insulation layer 400. It is understood that in this embodiment, the insulation layer 400 is disposed inside the outer casing of the heat pump device 2000, forming a thermal barrier that separates the cold air in the inner cavity 101 from the outer casing. This prevents direct contact between the cold air and the relatively warm chassis structure 100, side plate 200, and top cover 300, and prevents the outer casing from being simultaneously affected by two types of air with significant temperature differences. In other words, the cold air in the inner cavity 101 will not come into contact with the chassis structure 100, side plate 200, and top cover 300, thereby reducing the possibility of condensation on the outer casing.
[0067] Referring to Figures 3 and 4, in an embodiment of this application, the insulation layer 400 includes a first insulation layer 410, which is disposed at the chassis structure 100. Specifically, in this embodiment, the chassis structure 100 is a split structure, including a water receiving tray 110 and a support tray 120. The water receiving tray 110 and the support tray 120 are arranged along the height direction of the housing assembly 1000. The water receiving tray 110 is located above the support tray 120, that is, the water receiving tray 110 is located on the relatively inner side, and it is in direct contact with the cold air in the inner cavity 101. Therefore, the temperature of the water receiving tray 110 is relatively low. Correspondingly, the support tray 120 is located on the relatively outer side, and it is in direct contact with the indoor environment. Therefore, the temperature of the support tray 120 is relatively higher.
[0068] Referring again to Figures 3 and 4, in one example, the water receiving tray 110 is made of metal, while the support tray 120 is made of plastic. To prevent heat transfer from the water receiving tray 110 to the support tray 120, in this embodiment, a first insulation layer 410 is disposed between the water receiving tray 110 and the support tray 120, thereby separating the two and preventing heat transfer from the water receiving tray 110 to the support tray 120. Specifically, the upper surface of the first insulation layer 410 is adapted to the lower end surface of the water receiving tray 110, thus covering the lower end surface of the water receiving tray 110; the lower surface of the first insulation layer 410 is adapted to the upper end surface of the support tray 120, thus covering the upper end surface of the support tray 120.
[0069] Referring to Figures 3 and 4, in the embodiments of this application, in order to improve the water collection capacity of the water receiving tray 110 and reduce the risk of water leakage from the edge of the water receiving tray 110, a first periphery 112 is provided on the outer periphery of the water receiving tray 110. The first periphery 112 protrudes upward from the upper surface of the water receiving tray 110, thereby preventing water overflow. A second periphery 121 is formed by protruding upward from the outer periphery of the support plate 120. The second periphery 121 and the upper surface of the support plate 120 define a receiving groove 122. In order to reduce the contact between the first periphery 112 and the second periphery 121, a third periphery 411 is provided on the outer periphery of the first insulation layer 410. The third periphery 411 is located between the first periphery 112 and the second periphery 121, thereby separating the first periphery 112 and the second periphery 121, avoiding direct contact between the first periphery 112 and the second periphery 121, and preventing the water receiving tray 110 from transferring cold to the support plate 120.
[0070] To connect the water receiving tray 110, the first insulation layer 410, and the support plate 120, as shown in Figures 4 and 5, in the embodiments of this application, the chassis structure 100 further includes multiple connectors 130. The number of connectors 130 can be 4, 5, 8, etc., and the multiple connectors 130 are evenly arranged on the water receiving tray 110, with intervals between them. Referring to Figure 6, in one example, there are 4 connectors 130, each positioned near the edge of the water receiving tray 110, thereby minimizing contact between the connectors 130 and the cold air in the inner cavity 101.
[0071] Referring to Figure 4, in an embodiment of this application, the connector 130 is sequentially inserted through the water receiving tray 110, the first insulation layer 410, and the support plate 120 along the direction from the water receiving tray 110 toward the support plate 120. In one example, one end of the connector 130 is connected to the water receiving tray 110, and the other end extends downward and protrudes from the lower end face of the water receiving tray 110. When assembling the chassis structure 100, assembly can be completed simply by sequentially fitting the first insulation layer 410 and the support plate 120 into the connector 130, reducing the assembly difficulty of the chassis structure 100.
[0072] In the embodiments of this application, one end of the connector 130 is fixedly connected to the water receiving tray 110, and the other end is fixedly connected to the support plate 120. The water receiving tray 110 and the support plate 120 are indirectly connected through the connector 130, thereby clamping the first insulation layer 410 and improving the overall structural stability of the chassis structure 100. It should be noted that the connector 130 can be welded to the water receiving tray 110 or connected to the water receiving tray 110 by fasteners; the connector 130 and the support plate 120 can be connected by fasteners or by snap-fit connections, and this embodiment does not limit this.
[0073] It is understood that in the embodiments of this application, the water receiving tray 110 and the support tray 120 are connected only by the connector 130. This not only ensures that the first insulation layer 410 can be firmly clamped between the water receiving tray 110 and the support tray 120, and continuously maintains the interval between the water receiving tray 110 and the support tray 120, but also effectively reduces the direct contact area between the water receiving tray 110 and the support tray 120, minimizing the connection between the water receiving tray 110 and the support tray 120, thereby further reducing the possibility of the water receiving tray 110 transferring cold to the support tray 120.
[0074] Referring to FIG3, in an embodiment of this application, a water collection trough 111 for collecting water is formed in the central recess of the water receiving tray 110. In order to prevent the connector 130 from being soaked in condensate for a long time, in this embodiment, the upper end of the connector 130 is configured to be higher than the water collection trough 111 along the height direction of the housing assembly 1000. This not only reduces the risk of the connector 130 being corroded by condensate and extends the service life of the connector 130, but also prevents condensate from flowing along the connector 130. Specifically, it prevents condensate from penetrating into the first insulation layer 410, reducing the risk of condensate eroding the first insulation layer 410 and causing its insulation performance to decline, and also avoids condensate flowing into the support plate 120 and lowering the temperature of the support plate 120, thereby reducing the possibility of additional condensate generation.
[0075] Referring to Figure 5, in an embodiment of this application, the chassis structure 100 further includes multiple foot pads 140. The number of foot pads 140 can be 4, 5, 8, etc., and the number of foot pads 140 is the same as the number of connecting members 130. Therefore, the foot pads 140 and connecting members 130 are arranged in a one-to-one correspondence. Specifically, the foot pads 140 are disposed on the lower side of the support plate 120. One end of the connecting member 130 is fixed to the water receiving tray 110, and the other end protrudes from the lower end face of the support plate 120. Therefore, the foot pads 140 are connected to the end of the connecting member 130 protruding from the support plate 120. When the foot pads 140 are connected to the connecting member 130, they can abut against the support plate 120, and the multiple foot pads 140 can cooperate to support the support plate 120.
[0076] In one example, the foot pad 140 is made of rubber and can be placed directly on the indoor floor or mounted on a support structure such as a bracket. Understandably, the foot pad 140 is designed to prevent the chassis structure 100 from transferring heat to the indoor floor or its mounted support structure.
[0077] It is understandable that functional components such as the first heat exchanger 201 and the compressor 203 are often fixed to the chassis structure 100. Therefore, the chassis structure 100 needs to have high structural strength to ensure the overall stability of the functional components. However, the support plate 120 is made of plastic, resulting in limited load-bearing capacity. Therefore, referring to FIG6, in the embodiment of this application, the chassis structure 100 also includes at least two support members 150. For ease of description, the following description assumes that there are two support members 150.
[0078] Referring to Figures 4 and 6, in the embodiments of this application, two carrier members 150 are spaced apart along the width direction of the chassis structure 100 and disposed on the lower side of the support plate 120 and attached to the lower end surface of the support plate 120. The carrier members 150 extend along the length direction of the chassis structure 100, thereby providing more stable and stronger support for the functional components arranged along the length direction of the chassis structure 100 in the inner cavity 101.
[0079] To assemble the support member 150, referring to Figure 5, in this embodiment of the application, four connectors 130 are provided. Two connectors 130 and one support member 150 form a group. Specifically, the two connectors 130 are respectively inserted at both ends of the support member 150 along its length. Specifically, along the direction from the water receiving tray 110 to the support plate 120, the connectors 130 sequentially pass through the water receiving tray 110, the first insulation layer 410, the support plate 120, the support member 150, and the foot pad 140. The foot pad 140 can press the support member 150 tightly against the lower end face of the support plate 120. In one example, the support member 150 is a metal sheet.
[0080] Referring again to Figure 5, in the embodiments of this application, each carrier 150 has fixing holes 151 at both ends along its length. The connector 130 is a rod-shaped structure, and the size and shape of the fixing holes 151 match those of the connector 130. Therefore, the connector 130 passes through the fixing holes 151 to be fixedly connected to the foot pad 140. The chassis structure 100 also includes a partition 160, which is disposed within the fixing holes 151. The partition 160 has an opening suitable for the connector 130 to pass through, and is fitted onto the connector 130. It is understood that the partition 160 extends axially along the connector 130, thereby separating the inner wall of the fixing hole 151 from the outer peripheral wall of the connector 130, effectively isolating the connector 130 and the carrier 150, and reducing the possibility of heat transfer from the connector 130 to the carrier 150.
[0081] Referring again to Figure 5, in one example, a nut 141 is embedded in the upper side of the foot pad 140, and the lower end of the connector 130 has an external thread that matches the nut 141, thereby achieving a threaded connection between the connector 130 and the foot pad 140. It can be understood that the upper side of the foot pad 140 can be provided with a metal connection structure that can achieve a fixed connection with the connector 130, similar to the nut 141. Based on this, since both the bearing member 150 and the connection structure are metal parts, heat exchange is easily possible between them. In this embodiment, to prevent the carrier 150 from transferring heat to the metal connection structure, the partition 160 has a partition portion 161 at one end facing the foot pad 140. The partition portion 161 extends radially away from the connector 130. Therefore, the partition portion 161 is located between the carrier 150 and the foot pad 140, thereby separating the carrier 150 and the foot pad 140 and effectively isolating them, reducing the possibility of the carrier 150 transferring heat to the foot pad 140. It is understood that when assembling the partition 160, the partition 160 can also be positioned and engaged with the fixing hole 151, thereby improving the assembly efficiency of the partition 160.
[0082] Referring to FIG7, in an embodiment of this application, the insulation layer 400 includes a second insulation layer 420. The second insulation layer 420 is disposed on the lower side of the top cover 300 and covers the lower end surface of the top cover 300, thereby separating the top cover 300 from the inner cavity 101 and preventing cold air in the inner cavity 101 from directly contacting the top cover 300. To match the top cover 300, the second insulation layer 420 has two through slots 421 arranged side-by-side. The two through slots 421 are respectively corresponding to the air outlet 320. One through slot 421 communicates with the air inlet 310, and the other through slot 421 communicates with the air outlet 320.
[0083] Referring to Figures 8, 9, and 10, in the embodiments of this application, the inner wall of the through groove 421 is transitionally connected to the upper end face of the second insulation layer 420 via a step 422. Correspondingly, the lower end face of the top cover 300 is provided with two connecting portions 330 corresponding one-to-one with the two through grooves 421. The two connecting portions 330 are annular structures protruding downward from the lower end face of the top cover 300. Based on this, the cross-section of the step 422 is also annular. The connecting portions 330 pass through the through grooves 421 and are at least partially located on the step 422. In one example, the lower end face of the connecting portion 330 is in contact with the upper end face of the step 422.
[0084] Referring to FIG10, in an embodiment of this application, a first sealing element 423 is provided at the step 422. The first sealing element 423 may be an annular sponge element, and the first sealing element 423 is sleeved on the connecting part 330. It can be understood that the cooperation of the connecting part 330, the first sealing element 423, and the step 422 enhances the sealing between the second insulation layer 420 and the top cover 300, thereby improving the insulation performance of the second insulation layer 420 and further reducing the possibility of cold air in the inner cavity 101 contacting the top cover 300 and causing condensation to form on the surface of the top cover 300.
[0085] Referring to Figures 7 and 8, in the embodiments of this application, the lower end of the top cover 300 protrudes downward to form a plurality of positioning posts 340, which are spaced apart. Correspondingly, the upper end of the second insulation layer 420 is recessed downward to form a plurality of positioning grooves 424, which are correspondingly arranged with the positioning posts 340. The positioning posts 340 pass through the positioning grooves 424 and are interference-fitted with the positioning grooves 424, thereby achieving a fixed connection between the top cover 300 and the second insulation layer 420.
[0086] In one example, four positioning posts 340 are provided, and the top cover 300 is generally square plate-shaped. Based on this, the four positioning posts 340 can be arranged near the four corners of the top cover 300, thereby dispersing the connection stress and further enhancing the stability of the connection. It can be understood that, compared with the method of connection by fasteners, the interference fit between the positioning posts 340 and the positioning grooves 424 not only simplifies the assembly process of the second insulation layer 420, but also minimizes the heat exchange between the top cover 300 and the cold air in the inner cavity 101, thereby improving the insulation performance of the second insulation layer 420.
[0087] Referring to Figures 8 and 11, in the embodiments of this application, the upper surface of the top cover 300 protrudes upward to form two air guide rings 350. One air guide ring 350 communicates with the air inlet 310, and the other air guide ring 350 communicates with the air outlet 320. It is understood that the air temperature passing through the air inlet 310 and the air outlet 320 is relatively low. To prevent condensation from forming on the air guide rings 350 and the surrounding upper surface of the top cover 300, in this embodiment, the insulation layer 400 further includes a third insulation layer 430, the shape of which matches the upper side of the top cover 300.
[0088] Referring to FIG8, in an embodiment of this application, the third insulation layer 430 includes an adhesive portion 431 and two surrounding portions 432. The adhesive portion 431 has a plate-like structure and is attached to the upper surface of the top cover 300. It should be noted that in this embodiment, the adhesive portion 431 may completely cover the upper surface of the top cover 300, or it may only cover a portion of the upper surface of the top cover 300 based on appearance requirements. This embodiment does not limit this.
[0089] Referring again to Figure 8, in this embodiment of the application, two surrounding portions 432 are spaced apart from and pass through the fitting portion 431. The surrounding portions 432 can form a slot through which the air guide ring 350 passes, and the air guide ring 350 passes through the slot. It can be understood that the surrounding portions 432 wrap around the outside of the air guide ring 350, and the surface of the upper end face of the top cover 300 near the air guide ring 350 is covered with the fitting portions 431. Therefore, the third insulation layer 430 can reduce the heat exchange between the cold air flowing through the air inlet 310 and the air outlet 320 and the indoor environment, thereby reducing the possibility of condensation on the upper side of the top cover 300.
[0090] It is understandable that the end face of the top cover 300 may be uneven. Therefore, in this embodiment, a first filler layer (not shown in the figure) is provided between the adhesive portion 431 and the top cover 300. In this embodiment, the first filler layer can be adhesive backing or sponge; this embodiment is not limited in this respect. The first filler layer can fill the gap between the upper end face of the top cover 300 and the adhesive portion 431, thereby improving the sealing between the top cover 300 and the third insulation layer 430, and thus improving the insulation performance of the third insulation layer 430.
[0091] Referring to FIG1, in an embodiment of this application, the side panel 200 includes a front panel 210 and a rear panel 220, wherein the front panel 210 and the rear panel 220 are arranged along the front-rear direction of the housing assembly 1000, with the front panel 210 located on the opposite front side and the rear panel 220 located on the opposite rear side. It should be noted that the front panel 210 forms the front inner wall of the cavity 101, and the rear panel 220 forms the rear inner wall, left inner wall, and right inner wall of the cavity 101.
[0092] Referring to FIG12, in an embodiment of this application, the insulation layer 400 further includes a fourth insulation layer 440. The fourth insulation layer 440 is disposed on the inner side of the rear panel 220, covering the inner surface of the rear panel 220, and a second filler layer (not shown in the figure) is filled between the fourth insulation layer 440 and the rear panel 220. It is understood that the fourth insulation layer 440 can separate the rear panel 220 from the inner cavity 101, preventing cold air in the inner cavity 101 from directly contacting the rear panel 220. In this embodiment, the second filler layer can be adhesive or sponge; this embodiment is not limited in this respect. The second filler layer can fill the gap between the inner surface of the rear panel 220 and the fourth insulation layer 440, thereby improving the sealing between the rear panel 220 and the fourth insulation layer 440, and thus improving the insulation performance of the fourth insulation layer 440.
[0093] Referring to FIG13, in an embodiment of this application, the insulation layer 400 further includes a fifth insulation layer 450. The fifth insulation layer 450 is disposed on the inner side of the front panel 210, covering the inner surface of the front panel 210, and a third filler layer (not shown in the figure) is filled between the fifth insulation layer 450 and the front panel 210. It is understood that the fifth insulation layer 450 can separate the front panel 210 from the inner cavity 101, preventing cold air in the inner cavity 101 from directly contacting the front panel 210. In this embodiment, the third filler layer can be adhesive or sponge; this embodiment is not limited in this respect. The third filler layer can fill the gap between the inner surface of the front panel 210 and the fifth insulation layer 450, thereby improving the sealing between the front panel 210 and the fifth insulation layer 450, and thus improving the insulation performance of the fifth insulation layer 450.
[0094] Referring to Figure 14, in this embodiment of the application, the housing assembly 1000 further includes a bracket 500, wherein the bracket 500 is disposed on the inner side of the rear panel 220, and the fourth insulation layer 440 is disposed between the bracket 500 and the rear panel 220. As can be understood from Figures 12 and 15, in this embodiment, a first mounting portion 510 is provided on the upper side of the bracket 500, and the upper end of the rear panel 220 is fixedly connected to the first mounting portion 510. It should be noted that the rear panel 220 and the first mounting portion 510 can be connected by fasteners, by welding, or by other types of fixed connection methods; this embodiment does not limit this.
[0095] Referring to Figures 12 and 16, it can be understood that in this embodiment, a second mounting portion 520 is provided on the lower side of the bracket 500, and the lower end of the rear panel 220 is fixedly connected to the second mounting portion 520. It should be noted that the rear panel 220 and the second mounting portion 520 can be connected by fasteners, welding, or other types of fixed connection methods; this embodiment does not limit this. It can be understood that in this embodiment, by connecting the rear panel 220 to the first mounting portion 510 and the second mounting portion 520 respectively, the fourth insulation layer 440 is clamped, improving the overall structural stability.
[0096] If both the first mounting portion 510 and the second mounting portion 520 are directly exposed to the cold air in the inner cavity 101, the first mounting portion 510 and the second mounting portion 520 will transfer cold air to the rear panel 220, resulting in condensation on the surface of the rear panel 220. Therefore, referring to Figures 7 and 15, in the embodiment of this application, a baffle 425 protrudes from the lower end face of the fourth insulation layer 440. The baffle 425 is arranged circumferentially along the rear panel 220, located on the side of the first mounting portion 510 facing the inner cavity 101, and is in contact with the first mounting portion 510, thereby separating the first mounting portion 510 from the inner cavity 101 and preventing the cold air in the inner cavity 101 from directly contacting the first mounting portion 510.
[0097] Referring to FIG16, in the embodiment of this application, the second mounting part 520 is connected to the support plate 120. It is understood that the first insulation layer 410 is disposed between the water receiving tray 110 and the support plate 120. Therefore, the first insulation layer 410 not only prevents the water receiving tray 110 from transferring heat to the support plate 120, but also prevents the water receiving tray 110 from transferring heat to the second mounting part 520. Specifically, the second mounting part 520 is located outside the second perimeter 121, and the third perimeter 411 can separate the second perimeter 121 from the first perimeter 112, thereby preventing the water receiving tray 110 from transferring heat to the second mounting part 520. It should be noted that the second mounting part 520 can be connected to the support plate 120 by fasteners or can be snapped onto the support plate 120; this embodiment does not limit this.
[0098] Referring to FIG14, in an embodiment of this application, the rear panel 220 includes a bending portion 221. In one example, the rear panel 220 has a split structure, with two bending portions 221 connected to each other to form the rear panel 220. Based on this, and referring to FIG17, it can be understood that the fourth insulation layer 440 includes a first insulation portion 441 and a second insulation portion 442, which are connected to each other. To match the bending portions 221, in this embodiment, the first insulation portion 441 and the second insulation portion 442 are arranged at an included angle to each other; for example, the first insulation portion 441 and the second insulation portion 442 are perpendicular to each other.
[0099] Referring again to FIG17, in this embodiment of the application, a second sealing member 443 is provided between the first panel portion 211 and the second panel portion 212. The second sealing member 443 has a bent structure, with one end attached to the first panel portion 211 and the other end attached to the second panel portion 212, thereby sealing the gap between the first panel portion 211 and the second panel portion 212 and improving the sealing performance of the fourth insulation layer 440. It should be noted that in this embodiment, the second sealing member 443 can be adhesive or sponge, and this embodiment is not limited in this regard.
[0100] Referring to Figures 2 and 19, in this embodiment of the application, an air guide 205 is provided inside the air outlet cavity 103, and an air duct is formed inside the air guide 205. A fan 204 is disposed inside the air duct, and the air duct is connected to the air outlet 320. In this embodiment, the air guide 205 is made of thermal insulation material; therefore, the cold air located in the air duct will not be transferred to the air in the air outlet cavity 103. Based on this, in this embodiment, only the portion of the front panel 210 located in the air inlet cavity 102 needs to be provided with an insulation layer 400 to meet the insulation requirements.
[0101] Referring to FIG18, in an embodiment of this application, the front panel 210 includes a first panel portion 211 and a second panel portion 212, which are integrally formed. The first panel portion 211 is located in the air inlet cavity 102, the second panel portion 212 is located in the air outlet cavity 103, and the fifth insulation layer 450 covers the inner surface of the second panel portion 212.
[0102] Referring to Figures 19 and 20, in the embodiments of this application, a partition plate 206 is provided on the side of the first heat exchanger 201 facing away from the air inlet cavity 102. Referring to Figures 14 and 20, an abutment portion 222 is provided at one end of the rear panel 220 located in the air inlet cavity 102. Specifically, the abutment portion 222 is located on the front side of the rear panel 220 at one end of the air inlet cavity 102. Correspondingly, one end of the fifth insulation layer 450 is bent toward the rear panel 220 to form a first bending portion 451, and the other end is bent toward the partition plate 206 to form a second bending portion 452.
[0103] Referring to Figure 20, in one example, the right side of the inner cavity 101 is the air inlet cavity 102, and the left side is the air outlet cavity 103. Based on this, the front side of the right end of the rear panel 220 is provided with an abutment portion 222, and the partition plate 206 is located on the left side of the first heat exchanger 201. The first bending portion 451 is provided on the right side of the fifth insulation layer 450 and abuts against the abutment portion 222, and the second bending portion 452 is provided on the left side of the fifth insulation layer 450 and abuts against the partition plate 206, thereby achieving the sealing of the air inlet cavity 102, improving the sealing performance of the air inlet cavity 102, and further reducing the possibility of cold air in the air inlet cavity 102 directly contacting the rear panel 220 and the front panel 210.
[0104] Referring to Figure 21, in the embodiment of this application, the minimum thickness of the insulation layer 400 is w, which satisfies: w ≥ 6 mm. It can be understood that the minimum thickness of the insulation layer 400 refers to the thickness of the thinnest point among the first insulation layer 410, the second insulation layer 420, the third insulation layer 430, the fourth insulation layer 440, and the fifth insulation layer 450. For ease of description, the first insulation layer 410 will be used as an example below. Referring to Figure 4, in this embodiment, the thinnest point of the first insulation layer 410 is the shortest distance between its upper and lower surfaces. For example, the thinnest point of the first insulation layer 410 could be its central position.
[0105] Understandably, the inventors discovered through numerous experiments that if the minimum thickness of the insulation layer 400 is too small, it will not only result in insufficient structural strength of the insulation layer 400, but also severely weaken its insulation performance, making it unable to meet the requirements for blocking cold transfer. Therefore, by rationally designing the range of the minimum thickness w of the insulation layer 400, it is possible to effectively exert its insulation function and achieve the required thermal insulation effect while ensuring that the insulation layer 400 has sufficient structural strength.
[0106] This application also proposes a heat pump device 2000, including a first heat exchanger 201, a second heat exchanger 202, a compressor 203, a fan 204, and the housing assembly 1000 described in the above embodiments. The first heat exchanger 201 divides the inner cavity 101 into an air inlet cavity 102 and an air outlet cavity 103. The air inlet cavity 102 communicates with an air inlet 310, and the air outlet cavity 103 communicates with an air outlet 320. The second heat exchanger 202 and the compressor 203 are installed in the air inlet cavity 102. The second heat exchanger 202 is a plate heat exchanger, and the fan 204 is installed in the air outlet cavity 103. It is understood that the heat pump device 2000 can be a heat pump water heater or a heat pump heating device, and this embodiment does not limit it in this way.
[0107] The heat pump device 2000 adopts the housing assembly 1000 of the above embodiment, which is formed by setting a chassis structure 100, side plates 200 and a top cover 300. The side plates 200 are connected to the chassis structure 100 and the top cover 300 respectively, thereby forming the outer shell of the heat pump device 2000. The chassis structure 100, side plates 200 and top cover 300 enclose an inner cavity 101, which is used to install a first heat exchanger 201, a second heat exchanger 202, a compressor 203 and a fan 204. The top cover 300 is equipped with an insulation layer 400, which forms a heat insulation barrier to isolate the cold air in the inner cavity 101 from the warm air in the indoor environment. This prevents the outer shell from contacting both the cold air in the inner cavity 101 and the warm air in the indoor environment at the same time, thereby reducing the possibility of condensation on the outer shell of the heat pump equipment 2000. This not only reduces the risk of condensation corroding the outer shell of the heat pump equipment 2000, but also avoids the need for users to frequently clean the condensate, reducing the difficulty of use for users and improving the user experience.
[0108] Since the heat pump device 2000 adopts all the technical solutions of the housing assembly 1000 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0109] Of course, this application is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this application. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
