Through a series of heat exchange processes, heat is extracted to provide hot water or indoor heating. To reduce the likelihood of condensation on the surface of the plastic cover, insulation is often installed on the inner and outer sides to block heat transfer. However, because the metal filters installed at the air inlet and outlet are in direct contact with the ducts, low temperatures can still be conducted through the metal filters to the surface of the plastic cover, leading to condensation.

[0007] The top cover assembly of this utility model sets the air guide ring on the insulation component and embeds the mounting component inside the air guide ring, so that the insulation component acts as a heat insulation barrier between the cold air and the cover. By configuring the mounting component, the mounting component protrudes from the inner peripheral wall of the air guide ring towards the central axis of the air outlet, so that the filter can be fixed to the mounting component, thus realizing the assembly of the filter. The insulation component separates the air flowing through the air outlet from the annular part sleeved on the outside of the air guide ring, thereby cutting off the path of cold air to the cover and preventing the cover from being affected by two airs with large temperature differences at the same time, thereby reducing the possibility of condensation on the outer surface of the cover.

[0016] The heat pump device according to the embodiments of this utility model has at least the following beneficial effects:

[0017] The heat pump device adopts the top cover assembly of the first aspect embodiment. The heat pump device separates the air flowing through the air outlet from the annular part sleeved on the outside of the air guide ring through the insulation component, thereby cutting off the path of cold air to the cover and preventing the cover from being affected by two airs with large temperature differences at the same time. This reduces the possibility of condensation on the outer surface of the cover, which not only reduces the risk of condensation corroding the shell of the heat pump device, but also avoids the need for users to clean condensation frequently, reducing the difficulty of use for users and improving the user experience.

[0043] 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.

[0044] 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.

[0045] 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 or the order of the technical features.

[0046] 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.

[0047] 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. When the air inside the heat pump equipment is maintained at a relatively low temperature range (e.g., 0℃ to -20℃), while the indoor environment is relatively warm, the temperature of the heat pump equipment's outer casing exposed to the indoor environment is also relatively high. To reduce the possibility of condensation on the surface of the plastic top cover, insulation is often installed on the inner and outer sides of the plastic top cover to block heat transfer.

[0048] However, due to manufacturing errors and other factors, the surfaces of the plastic top cover and the insulation component are not perfectly smooth, resulting in gaps at the connection points. Cold air escaping through these gaps comes into contact with the plastic top cover, causing condensation to form on its surface. Furthermore, because the metal filters installed at the air inlet and outlet are in direct contact with the ductwork, low temperatures can still be conducted through the metal filters to the surface of the plastic top cover, further promoting condensation. The generation of condensation can not only accelerate the corrosion process of the heat pump equipment's casing, shortening its lifespan, but also negatively impact the indoor environment, such as causing slippery floors and promoting the growth of mold and bacteria.

[0049] To address the aforementioned problems, some embodiments of this utility model provide a top cover assembly 1000 suitable for heat pump devices. For example, the heat pump device may be a heat pump water heater, as detailed below. Figures 1 to 10The top cover assembly 1000 is described as shown.

[0050] For ease of description, the following description will use an example of a top cover assembly 1000 applied to a heat pump unit having a first heat exchanger 800, a second heat exchanger, a compressor, and a fan 900. (Refer to...) Figure 1 As shown, in this embodiment of the present invention, the heat pump device includes a housing 700 and a top cover assembly 1000. Specifically, the housing 700 is a semi-open structure with the opening facing upwards, and the top cover assembly 1000 is disposed on the upper side of the housing 700 and connected to the housing 700. In this embodiment, the top cover assembly 1000 and the housing 700 together enclose the inner cavity of the heat pump device, and the top cover assembly 1000 and the housing 700 serve as the outer shell of the heat pump device. It should be noted that the housing 700 and the top cover assembly 1000 can be detachably connected. For example, they can be connected by fasteners or by snap-fit ​​connections, etc. This embodiment does not limit this.

[0051] Continue to refer to Figure 1 As shown, in this embodiment of the invention, the first heat exchanger 800 is located in the middle of the inner cavity and can divide the inner cavity into an air inlet cavity 710 and an air outlet cavity 720. The second heat exchanger and compressor are disposed in the air inlet cavity 710, while the fan 900 is disposed in the air outlet cavity 720. (Combined with...) Figure 2 It is understood that in this embodiment, the top cover assembly 1000 includes a filter 100, a heat insulation component 200, an installation component 300, and a cover 400. The heat insulation component 200 is provided with an air guide ring 210, which is an annular structure. Therefore, the air guide ring 210 can form an air passage 211.

[0052] Reference Figure 1 and Figure 2 As shown, in this embodiment of the invention, two air guide rings 210 protrude from the upper surface of the insulation component 200. The two air guide rings 210 are spaced apart, and each air guide ring 210 defines an air passage 211. In this embodiment, one air passage 211 is an air inlet 2111, and the other air passage 211 is an air outlet 2112. The air inlet 2111 communicates with the air inlet cavity 710. (Refer to...) Figure 3 As shown, the air outlet 2112 is connected to the air duct 910 in the fan 900 located in the air outlet cavity 720. In one example, the air inlet 2111 and the air outlet 2112 are connected to the outdoor environment through the air duct 600. The cold outdoor air can enter the air inlet cavity 710 through the air inlet 2111, then flow through the first heat exchanger 800 for heat exchange, then enter the air outlet cavity 720, and finally return to the outdoor environment through the air outlet 2112.

[0053] It is understood that in this embodiment of the present invention, the cover 400 can serve as an exterior component of the top cover assembly 1000, and it is typically made of plastic. Since the heat pump equipment is installed in a relatively high-temperature indoor environment, to prevent condensation from forming on the surface of the cover 400 due to direct contact between the cold air in the inner cavity and the warm cover 400, the cover 400 is positioned above the insulation component 200. Specifically, the cover 400 covers the upper surface of the insulation component 200. The cover 400 has an annular portion 410 that matches the air guide ring 210. The annular portion 410 is fitted onto the outside of the air guide ring 210, thereby separating the cover 400 from the inner cavity through the insulation component 200. This prevents the cover 400 from being affected by two air sources with significant temperature differences, thus reducing the possibility of condensation forming on the outer surface of the cover 400. In one example, the insulation component 200 is integrally molded from foam material.

[0054] To fix the filter 100 in place and prevent it from becoming a heat conduction path between the cold air and the cover 400, refer to Figure 2 and Figure 4 As shown, in this embodiment of the present invention, the mounting component 300 is embedded within the air guide ring 210. Specifically, in this embodiment, the mounting component 300 includes a mounting member 310, which extends toward the central axis of the air outlet 211 and protrudes from the inner peripheral wall of the air guide ring 210. Based on this, the filter 100 can be detachably mounted to the mounting member 310, thereby achieving rapid assembly of the filter 100. It should be noted that the filter 100 and the mounting member 310 can be connected by screws or by detachable connection methods such as snap-fit ​​connections; this embodiment does not limit this connection.

[0055] It is understood that by embedding the mounting component 300 into the air guide ring 210, the insulation component 200 separates the mounting component 300 from the cold air flowing through the air outlet 211, reducing the possibility of cold air being transferred to the mounting component 300 and providing a fixed position for the filter 100. On the other hand, the insulation component 200 also separates the cold air from the annular portion 410 sleeved on the air guide ring 210, thereby cutting off the path of cold air being transferred to the cover 400. Furthermore, the traditional design of double insulation components 200 is optimized to only provide insulation components 200 on the inner side of the cover 400. By separating the cold air in the inner cavity from the cover 400 through the insulation component 200, the possibility of cold air escaping from the mating gap is reduced, thereby preventing the cover 400 from being affected by two types of air with large temperature differences at the same time, and thus reducing the possibility of condensation on the outer surface of the cover 400.

[0056] Specifically, refer to Figure 2 and Figure 5As shown, in this embodiment of the present invention, the mounting component 300 further includes a connector 320, which is connected to the mounting component 310. In one example, the connector 320 is a metal ring, and the connector 320 and the mounting component 310 are integrally formed. The connector 320 is embedded in the air guide ring 210 and is arranged along the circumference of the air guide ring 210, thus the connector 320 has a ring structure. The insulation component 200 is a foam component. Specifically, in this embodiment, the mounting component 300 is placed in a mold before foaming, and then the foaming operation is performed, thereby realizing the integral forming of the insulation component 200 and the mounting component 300. This not only allows the mounting component 300 and the insulation component 200 to be tightly connected, improving the connection stability of the two, thereby improving the installation stability of the filter screen 100, but also further improves the insulation effect of the insulation component 200 and reduces the possibility of the connector 320 coming into contact with cold air.

[0057] Reference Figure 4 As shown, in this embodiment of the present invention, the connector 320 is spaced apart from the inner and outer peripheral walls of the air guide ring 210. Specifically, in one example, an installation groove 212 is formed between the inner and outer peripheral walls of the air guide ring 210. The installation groove 212 is spaced apart from the inner and outer peripheral walls of the air guide ring 210, and the connector 320 is embedded in the installation groove 212. Based on this, the inner side of the connector 320 is kept apart from the cold air located inside the air guide ring 210, and the outer side of the connector 320 is also spaced apart from the annular portion 410 sleeved on the outer side of the air guide ring 210. It should be noted that the formation of the installation groove 212 does not require additional processing steps, but is naturally formed during the integral foaming molding process of the mounting component 300 and the insulation component 200.

[0058] It is understandable that, in this embodiment, on the one hand, the insulation component 200 separates the connector 320 from the cold air flowing through the air outlet 211, reducing the possibility of cold air being transferred to the connector 320. At the same time, the mounting component 310 provides a fixed position for the filter 100. On the other hand, the insulation component 200 also separates the connector 320 from the annular portion 410 sleeved on the air guide ring 210, reducing the possibility of cold air being transferred to the annular portion 410 from the connector 320, further reducing the risk of cold air being transferred to the annular portion 410.

[0059] Continue to refer to Figure 2 and Figure 5As shown in this embodiment of the present invention, the mounting member 310 is a lug 311 protruding from the inner side of the connector 320. In this embodiment, at least two lugs 311 are provided. Specifically, there may be two, three, four, or five lugs 311, etc., and this embodiment does not limit this. In one example, there are four lugs 311, which are spaced apart circumferentially along the connector 320, and all four lugs 311 protrude from the inner peripheral wall of the air guide ring 210. The lugs 311 are provided with a first mounting hole 312, and the filter 100 is provided with a second mounting hole 110. The first mounting hole 312 and the second mounting hole 110 can be connected by a first fastener.

[0060] In one example, the first fastener is a screw, the first mounting hole 312 is a threaded hole that can engage with the screw thread, and the second mounting hole 110 is a hole that penetrates the filter screen 100. Therefore, the first fastener can pass through the hole in the filter screen 100 and engage with the threaded hole on the lug 311 to achieve a fastening connection via a threaded connection. It should be noted that the first fastener is not limited to a screw; it can also be a rivet, etc. The first fastener, the first mounting hole 312, and the second mounting hole 110 can be selected and configured according to actual conditions, and this embodiment does not impose any limitations on this.

[0061] Understandably, the inventors learned during testing that if the thickness of the air guide ring 210 along its radial direction is too thin, it will be difficult to effectively block the conduction of cold air to the cover 400, and at the same time, the air guide ring 210 will also be unable to provide stable support for the mounting assembly 300. Therefore, referring to... Figure 4 As shown, in this embodiment of the invention, the minimum thickness of the air guide ring 210 along its radial direction is W, satisfying: W ≥ 8 mm. It should be noted that the minimum thickness of the air guide ring 210 refers to the minimum distance between the inner and outer peripheral walls of the air guide ring 210. In this embodiment, by rationally designing the range of W, not only can the air guide ring 210 have sufficient heat insulation performance to effectively block cold air from reaching the annular portion 410, but it can also ensure that the air guide ring 210 has sufficient strength to support the mounting assembly 300 and the filter 100 mounted on the mounting assembly 300.

[0062] The inventors also discovered during testing that if the distance between the connector 320 and the inner peripheral wall of the air guide ring 210 is too small, on the one hand, the air guide ring 210 will have difficulty effectively blocking the conduction of cold air to the connector 320; on the other hand, it will also affect the installation stability of the mounting assembly 300. If the distance between the connector 320 and the outer peripheral wall of the air guide ring 210 is too small, the air guide ring 210 will have difficulty effectively blocking the conduction of cold air from the connector 320 to the cover 400, and will also affect the installation stability of the mounting assembly 300. Therefore, referring to... Figure 4As shown in this embodiment of the present invention, along the radial direction of the air guide ring 210, the minimum distance between the connector 320 and the inner peripheral wall of the air guide ring 210 is L1, and the minimum distance between the connector 320 and the outer peripheral wall of the air guide ring 210 is L2, satisfying: L1≥2mm, L2≥2mm.

[0063] It should be noted that the minimum distance between the connector 320 and the inner peripheral wall of the air guide ring 210 refers to the minimum distance between the inner side of the connector 320 and the air guide ring 210, and the minimum distance between the connector 320 and the outer peripheral wall of the air guide ring 210 refers to the minimum distance between the outer side of the connector 320 and the air guide ring 210. In this embodiment, by reasonably designing the ranges of L1 and L2, it is not only further ensured that the air guide ring 210 can effectively block the cold air flowing through the air outlet 211 from being transferred to the connector 320, but also that the air guide ring 210 can effectively block the cold air from being transferred to the annular portion 410, and that the air guide ring 210 has sufficient strength to support the mounting assembly 300 and the filter 100.

[0064] Reference Figure 7 and Figure 9 As shown, in this embodiment of the present invention, the outer periphery of the cover 400 is provided with a downwardly extending flange 420, which is integrally formed with the cover 400. When the cover 400 is placed on the insulation component 200, the flange 420 is arranged around the outer periphery of the insulation component 200. Specifically, the flange 420 and the lower surface of the cover 400 form a receiving groove 430. When the cover 400 is connected to the insulation component 200, the insulation component 200 is located in the receiving groove 430. On the one hand, the insulation component 200 can separate the flange 420 from the cold air in the inner cavity; on the other hand, the flange 420 can also cover the outer periphery of the insulation component 200, preventing the insulation component 200 from being exposed and enhancing the protective effect on the insulation component 200.

[0065] Reference Figure 6 and Figure 8 As shown, in this embodiment of the present invention, the top cover assembly 1000 further includes a bracket 500, which is disposed below the insulation component 200. Therefore, the insulation component 200 is located between the cover body 400 and the bracket 500. It can be understood that the bracket 500 can serve as a connector between the top cover assembly 1000 and the box body 700. The detachable connection between the bracket 500 and the box body 700 allows for a stable connection between the top cover assembly 1000 and the box body 700. In this embodiment, the cover body 400 is connected to the bracket 500, thereby clamping the insulation component 200 and improving the structural stability of the top cover assembly 1000.

[0066] Specifically, refer to Figure 6 and Figure 9As shown, in this embodiment of the invention, a latch 440 protrudes from the lower side of the cover 400, extending downwards. Correspondingly, a through groove 220 is provided in the insulation component 200 at the position corresponding to the latch 440, penetrating the insulation component 200. The bracket 500 is provided with a fastening position 510, and the latch 440 is fastened to the fastening position 510. Further, the latch 440 is provided with a first connecting hole 441, and the side wall of the bracket 500 is provided with a second connecting hole 520 that matches the first connecting hole 441. The second connecting hole 520 is located on one side of the fastening position 510. It can be understood that when the cover 400, the insulation component 200, and the bracket 500 are connected in sequence, the latch 440 passes through the through groove 220 and fastens to the fastening position 510, and the first connecting hole 441 communicates with the second connecting hole 520. Based on this, the first connecting hole 441 and the second connecting hole 520 can be connected by a second fastener. It should be noted that the second fastener can be a screw, a rivet, or other fasteners; this embodiment does not limit this.

[0067] Reference Figure 10 As shown in this embodiment of the invention, the lower side of the cover 400 is provided with a plurality of positioning portions 450, which are spaced apart. Correspondingly, the insulation component 200 is provided with a plurality of positioning grooves 230, which correspond one-to-one with the positioning portions 450. When the cover 400 is installed on the insulation component 200, the positioning portions 450 pass through the positioning grooves 230, playing a positioning role, thereby improving the assembly efficiency of the top cover assembly 1000 and reducing the assembly difficulty of the top cover assembly 1000.

[0068] Continue to refer to Figure 10 As shown, in this embodiment of the invention, the end face of the positioning part 450 facing the insulation component 200 is provided with a third connecting hole 451, and the bottom wall of the positioning groove 230 is provided with a through hole 231 corresponding to the third connecting hole 451. When the positioning part 450 passes through the positioning groove 230, the end face of the positioning part 450 abuts against the bottom wall of the positioning groove 230, and the third connecting hole 451 communicates with the through hole 231. The bracket 500 is provided with a fourth connecting hole 530 at the position corresponding to the third connecting hole 451 and the through hole 231. When the cover 400, the insulation component 200, and the bracket 500 are connected in sequence, the third connecting hole 451, the through hole 231, and the fourth connecting hole 530 communicate with each other. Based on this, the third connecting hole 451, the through hole 231, and the fourth connecting hole 530 can be connected by a third fastener. It should be noted that the third fastener can be a screw or a rivet, etc., and this embodiment does not limit this.

Specifically, in this embodiment, two air inlets 211 are provided at intervals, wherein the air inlet 211 communicating with the air inlet cavity 710 is the air inlet 2111, and the air inlet 2112 communicating with the air outlet cavity 720 is the air outlet 2112. Similarly, two ducts 600 are provided, which are respectively inserted into the air inlet 2111 and the air outlet 2112. It can be understood that, since the air guide ring 210 is located inside the annular portion 410, the duct 600 in this embodiment can be inserted through the air inlet 211, with the annular portion 410 and the duct 600 separated by the air guide ring 210.

[0073] In this embodiment of the utility model, the heat pump equipment also includes a side plate and a chassis structure. The side plate, the top cover assembly 1000 and the chassis structure together form an inner cavity. The inner cavity includes an air inlet cavity 710 and an air outlet cavity 720 that are spaced apart. There are two air vents 211, one of which is connected to the air inlet cavity 710 and the other is connected to the air outlet cavity 720.
