Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and in particular to a top cover assembly and a heat pump device. Background Technology

[0002] In related technologies, heat pump equipment is typically installed indoors, drawing in outdoor air through ducts as a heat source. 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. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a top cover assembly that can block the diffusion of cold air to the cover body, thereby reducing the possibility of condensation on the surface of the cover body.

[0004] This utility model also proposes a heat pump device including the above-mentioned top cover assembly.

[0005] According to a first aspect of the present invention, a top cover assembly includes: a heat insulation component, a grille, and a cover body. The heat insulation component is provided with an air guide ring, which surrounds and forms an air passage. The grille covers the air passage, and the edge of the grille is embedded in the air guide ring. The cover body covers the heat insulation component and is connected to the heat insulation component.

[0006] The top cover assembly according to the embodiments of the present utility model has at least the following beneficial effects:

[0007] The top cover assembly of this utility model sets the air guide ring on the insulation component and covers the air vent with a grille. The edge of the grille is then embedded in the air guide ring, making the insulation component a heat insulation barrier between the cold air and the cover. Based on the assembly of the grille, the insulation component separates the cold air flowing through the air vent from the cover, thereby blocking the heat transfer channel of the cold air extending to the cover through the grille. This prevents the cover from being affected by two airs with large temperature differences at the same time, and thus reduces the possibility of condensation on the outer surface of the cover.

[0008] According to some embodiments of the present invention, the grille includes a grille body and an mounting part. The grille body covers the air outlet, the mounting part is embedded in the air guide ring, the mounting part is arranged along the circumference of the air guide ring, and the mounting part and the grille body are arranged radially spaced along the air guide ring. The grille also includes a connecting part, which is disposed between the mounting part and the grille body. One end of the connecting part is connected to the mounting part, and the other end is connected to the grille body.

[0009] According to some embodiments of the present invention, the grille body, the connecting part, and the mounting part are integrally formed.

[0010] According to some embodiments of the present invention, the mounting portion is constructed as a ring structure, which is arranged around the outer periphery of the grille body.

[0011] According to some embodiments of the present invention, at least two connecting portions are arranged at intervals along the circumference of the mounting portion. One end of each connecting portion is connected to the outer peripheral wall of the grid body, and the other end is connected to the inner peripheral wall of the mounting portion. A through groove is defined between two adjacent connecting portions in the circumferential direction of the mounting portion. The insulation component is made of foam material, and the foam material fills at least a portion of the area of ​​each through groove.

[0012] According to some embodiments of this utility model, the minimum width of the through groove along the radial direction of the air guide ring is D, which satisfies: D≥8mm.

[0013] According to some embodiments of this utility model, along the axial direction of the air guide ring, the minimum thickness of the grille body is H, which satisfies: H≥1.5mm.

[0014] According to some embodiments of this utility model, the minimum thickness of the air guide ring along the radial direction is W, which satisfies: W≥8mm.

[0015] According to some embodiments of the present invention, along the radial direction of the air guide ring, the minimum distance between the mounting part and the inner peripheral wall of the air guide ring is L1, and the minimum distance between the mounting part and the outer peripheral wall of the air guide ring is L2, satisfying: L1≥2mm, L2≥2mm.

[0016] According to some embodiments of the present invention, the outer periphery of the cover is provided with a flange, the flange is arranged along the circumference of the cover, the flange and the lower surface of the cover form a receiving groove, and the heat insulation component is located in the receiving groove.

[0017] According to a second aspect of the present invention, a heat pump device includes a side plate, a chassis structure, a heat exchanger, and a top cover assembly as described in the first aspect embodiment. The side plate, the top cover assembly, and the chassis structure together enclose an inner cavity. The heat exchanger is disposed in the inner cavity and divides the inner cavity into an air inlet cavity and an air outlet cavity. Two air passages are provided, one of which connects to the air inlet cavity and the other air passage connects to the air outlet cavity.

[0018] The heat pump device according to the embodiments of this utility model has at least the following beneficial effects:

[0019] The heat pump device in this embodiment adopts the top cover assembly of the first aspect embodiment. By embedding the edge of the grille into the air guide ring, the insulation component acts as a heat insulation barrier between the cold air and the cover. Based on the assembly of the grille, the insulation component separates the cold air flowing through the air outlet from the annular part fitted on the outside of the air guide ring, thereby blocking the heat transfer channel of the cold air extending to the cover through the air grille. This prevents 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. This not only reduces the risk of condensation corroding the shell of the heat pump device, but also avoids the need for users to frequently clean the condensate, reducing the difficulty of use for users and improving the user experience.

[0020] According to some embodiments of the present invention, the heat pump device includes a duct, which is inserted into the air guide ring.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] To address the aforementioned problems, some embodiments of this utility model propose a top cover assembly 1000 suitable for a heat pump device 2000. For example, the heat pump device 2000 can be a heat pump water heater. See details below. Figures 1 to 8 The top cover assembly 1000 is described as shown.

[0045] For ease of description, the following description will use the application of the top cover assembly 1000 in a heat pump unit 2000 having a first heat exchanger, a second heat exchanger, a compressor, and a fan as an example. (Refer to...) Figure 1As shown, in this embodiment of the present invention, the heat pump device 2000 includes a housing 700 and a top cover assembly 1000. Specifically, the housing 700 has 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 2000, and the top cover assembly 1000 and the housing 700 serve as the outer shell of the heat pump device 2000. 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.

[0046] Continue to refer to Figure 1 As shown, in this embodiment of the invention, the first heat exchanger is located in the middle of the inner cavity and can divide the inner cavity into an air inlet cavity 410 and an air outlet cavity 420. The second heat exchanger and the compressor are located in the air inlet cavity 410, while the fan is located in the air outlet cavity 420. (Combined with...) Figure 3 It is understood that in this embodiment, the top cover assembly 1000 includes a thermal insulation component 100, a grille 200 and a cover body 300. The thermal insulation component 100 is provided with an air guide ring 110, which is an annular structure. Therefore, the air guide ring 110 can form an air passage 120.

[0047] Reference Figure 1 and Figure 2 As shown in this embodiment of the invention, two air guide rings 110 protrude from the upper surface of the insulation component 100. The two air guide rings 110 are spaced apart, and each air guide ring 110 defines an air outlet 120. In this embodiment, one air outlet 120 is an air inlet 121, and the other air outlet 120 is an air outlet 122. The air inlet 121 is connected to the air inlet cavity 410, and the air outlet 122 is connected to the air duct in the fan located in the air outlet cavity 420. In one example, the air inlet 121 and the air outlet 122 are connected to the outdoor environment through the air duct 600. Outdoor cold air can enter the air inlet cavity 410 through the air inlet 121, then flow through the first heat exchanger for heat exchange, then enter the air outlet cavity 420, and finally return to the outdoor environment through the air outlet 122.

[0048] Understandably, referring to Figure 3As shown, in this embodiment of the present invention, the cover 300 can serve as an exterior component of the top cover assembly 1000, and is typically made of plastic. Since the heat pump device 2000 is located in a relatively high-temperature indoor environment, to prevent condensation from forming on the surface of the cover 300 due to direct contact between the cold air in the inner cavity and the warm cover 300, the cover 300 is positioned above the insulation component 100. Specifically, the cover 300 covers the upper surface of the insulation component 100, and the cover 300 has an annular portion 310 that matches the air guide ring 110. The annular portion 310 is fitted onto the outside of the air guide ring 110, thereby separating the cover 300 from the inner cavity through the insulation component 100. This prevents the cover 300 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 300. In one example, the insulation component 100 is integrally molded from foam material.

[0049] In order to achieve the assembly of the grille 200 while avoiding the grille 200 becoming a heat conduction path between cold air and the cover 300, refer to Figure 2 and Figure 3 As shown, in this embodiment of the present invention, the grille 200 covers the air vent 120 and its edge is embedded in the air guide ring 110, so that the insulation component 100 acts as a heat insulation barrier between the cold air and the cover 300. On the basis of assembling the grille 200, the insulation component 100 separates the cold air flowing through the air vent 120 from the annular portion 310 sleeved on the outside of the air guide ring 110.

[0050] Specifically, refer to Figure 3 and Figure 4 As shown, in this embodiment of the present invention, the grille 200 includes a grille body 210 and a mounting portion 220 connected to each other. The grille body 210 is circular, corresponding to the air vent 120, and covers the air vent 120, thereby preventing foreign objects from entering the air inlet cavity 410 through the air vent 120. The mounting portion 220 extends circumferentially along the air guide ring 110 and is disposed around the outer periphery of the grille body 210. In one example, the mounting portion 220 may include multiple arc-shaped structures. In this embodiment, the mounting portion 220 is embedded in the air guide ring 110, so the grille 200 and the cover 300 are separated by the air guide ring 110, making the insulation member 100 a heat insulation barrier between the cold air and the cover 300.

[0051] It is understood that, based on the assembly of the grille 200, the top cover assembly 1000 of this utility model separates the cold air flowing through the air vent 120 from the annular portion 310 sleeved on the outside of the air guide ring 110 by the heat insulation component 100, thereby blocking the heat transfer channel of the cold air extending from the grille 200 to the cover 300, preventing the cover 300 from being affected by two airs with large temperature differences at the same time, and thus reducing the possibility of condensation on the outer surface of the cover 300.

[0052] Specifically, refer to Figure 4 As shown, in this embodiment of the present invention, the mounting portion 220 and the grille body 210 are arranged radially spaced along the air guide ring 110. Specifically, in this embodiment, the mounting portion 220 is constructed as an annular structure surrounding the outer periphery of the grille body 210. It can be understood that on the projection plane perpendicular to the axial direction of the air guide ring 110, the projection of the grille body 210 is circular, and the projection of the mounting portion 220 is an annular ring surrounding the outer side of the projection of the grille body 210, the inner diameter of which is larger than the outer diameter of the circle.

[0053] To connect the mounting portion 220 and the grille body 210, the grille 200 further includes a connecting portion 230. The connecting portion 230 is disposed between the mounting portion 220 and the grille body 210, with one end connected to the mounting portion 220 and the other end connected to the grille body 210. It is understood that because the mounting portion 220 and the grille body 210 are spaced apart, they are connected only by the connecting portion 230, thereby reducing direct contact between the mounting portion 220 and the grille body 210 and lowering the possibility of cold air from the grille body 210 diffusing to the mounting portion 220. In one example, the connecting portion 230, the mounting portion 220, and the grille body 210 are integrally formed.

[0054] Continue to refer to Figure 4 As shown, in this embodiment of the present invention, at least two connecting portions 230 are provided, and the at least two connecting portions 230 are arranged at intervals along the circumference of the air guide ring 110. For example, there may be two, three, four, or five connecting portions 230, etc., and this embodiment does not limit this. For ease of description, the following description uses four connecting portions 230 as an example. The connecting portion 230 is constructed as a connecting rib, with one end connected to the outer peripheral wall of the grille body 210 and the other end connected to the inner peripheral wall of the mounting portion 220. In this embodiment, along the axial direction of the air guide ring 110, the end faces of the connecting portion 230, the mounting portion 220, and the grille body 210 are all flush, thereby making the thickness of the grille 200 uniform.

[0055] Continue to refer to Figure 4As shown, in this embodiment of the invention, four connecting portions 230 are spaced apart, and a through groove 240 is defined between two adjacent connecting portions 230 along the circumference of the air guide ring 110. Specifically, the inner peripheral wall of the mounting portion 220, the outer peripheral wall of the grille body 210, and the side walls of the two connecting portions 230 together define the through groove 240 extending circumferentially along the air guide ring 110. Figure 5 It is understood that, in this embodiment of the present invention, at least a portion of the structure of each connecting part 230 is exposed in the air vent 120.

[0056] In this embodiment of the utility model, the insulation component 100 is a foamed component, which is made of foamed material through a foaming molding process. Specifically, refer to... Figure 6 and Figure 7 As shown, foam material fills at least a portion of each channel 240. It is understood that the channel 240 is located inside the mounting portion 220. In order to enclose the mounting portion 220 with the foam material, in one example, during foaming, the foam material fills a portion of the channel 240, leaving the remaining portion exposed at the air outlet 120. In another example, during foaming, the foam material fills the entire channel 240. Based on this, it is ensured that the mounting portion 220 is entirely enclosed within the air guide ring 110, further ensuring that the mounting portion 220 is separated from the cold air flowing through the air outlet 120.

[0057] Understandably, in order to ensure that the duct 240 has sufficient space to accommodate part of the air guide ring 110, refer to Figure 4 As shown in this embodiment of the invention, the minimum width of the through groove 240 along the radial direction of the air guide ring 110 is D, which satisfies: D≥8mm. It should be noted that the minimum width of the through groove 240 refers to the width of the narrowest point in the through groove 240. It is understood that when D<8mm, the accommodating space of the through groove 240 is too small, making it difficult to allow the foamed material to form within it, thus resulting in the foamed material inside the mounting portion 220 being unable to effectively prevent the diffusion of cold air to the mounting portion 220.

[0058] Combination Figure 7 It is understood that this embodiment ensures that the channel 240 has sufficient space to accommodate the foaming material by reasonably limiting the range of D, so that part of the air guide ring 110 can be formed in the channel 240, thereby ensuring that the foaming material located inside the mounting part 220 in the air guide ring 110 has sufficient thickness to effectively block the transfer of cold energy to the mounting part 220.

[0059] Reference Figure 7As shown, in this embodiment of the invention, the minimum thickness of the grille body 210 along the axial direction of the air guide ring 110 is H, satisfying: H ≥ 1.5 mm. It should be noted that the minimum thickness of the grille body 210 refers to the thickness at its thinnest point. It is understood that when H < 1.5 mm, the strength of the grille body 210 is too weak, and the grille 200 is prone to deformation. Since the mounting part 220 and the grille body 210 are connected only by the sheet-like connecting part 230, in order to ensure the overall structural strength of the grille 200, this embodiment reasonably limits the range of H, thereby ensuring that the grille body 210 has sufficient strength to provide reliable support, and thus improving the overall structural stability of the grille 200.

[0060] Understandably, the inventors learned during testing that if the thickness of the air guide ring 110 along its radial direction is too thin, it will be difficult to effectively block the conduction of cold air to the cover 300, and at the same time, the air guide ring 110 will also be unable to provide stable support for the mounting part 220. Therefore, referring to... Figure 7 As shown, in this embodiment of the invention, the minimum thickness of the air guide ring 110 along its radial direction is W, satisfying: W ≥ 8mm. It should be noted that the minimum thickness of the air guide ring 110 refers to the minimum distance between the inner and outer peripheral walls of the air guide ring 110. In this embodiment, when W < 8mm, an excessively thin air guide ring 110 not only fails to effectively block the diffusion of cold air, but also fails to support the installation of the grille 200. By rationally designing the range of W, it is possible not only to ensure that the air guide ring 110 has sufficient thermal insulation performance, thereby effectively blocking the diffusion of cold air to the annular portion 310, but also to ensure that the air guide ring 110 has sufficient strength to support the grille 200.

[0061] The inventors also discovered during testing that if the distance between the mounting part 220 and the inner peripheral wall of the air guide ring 110 is too small, on the one hand, the air guide ring 110 will be unable to effectively block the conduction of cold air to the mounting part 220, and on the other hand, it will also affect the installation stability of the grille 200; if the distance between the mounting part 220 and the outer peripheral wall of the air guide ring 110 is too small, the air guide ring 110 will be unable to effectively block the conduction of cold air from the mounting part 220 to the cover 300, and will also affect the installation stability of the grille 200. Therefore, referring to... Figure 7 As shown, in this embodiment of the present invention, along the radial direction of the air guide ring 110, the minimum distance between the mounting part 220 and the inner peripheral wall of the air guide ring 110 is L1, and the minimum distance between the mounting part 220 and the outer peripheral wall of the air guide ring 110 is L2, satisfying: L1≥2mm, L2≥2mm.

[0062] It should be noted that the minimum distance between the mounting part 220 and the inner peripheral wall of the air guide ring 110 refers to the minimum distance between the inner side of the mounting part 220 and the air guide ring 110, and the minimum distance between the mounting part 220 and the outer peripheral wall of the air guide ring 110 refers to the minimum distance between the outer side of the mounting part 220 and the air guide ring 110. In this embodiment, by reasonably designing the ranges of L1 and L2, it is not only further ensured that the air guide ring 110 can effectively block the diffusion of cold air flowing through the air outlet 120 to the mounting part 220, but also that the air guide ring 110 can effectively block the diffusion of cold air from the mounting part 220 to the annular part 310, and that the air guide ring 110 has sufficient strength to support the grille 200.

[0063] Reference Figure 3 and Figure 6 As shown, in this embodiment of the present invention, the outer periphery of the cover 300 is provided with a downwardly extending flange 320, which is integrally formed with the cover 300. When the cover 300 is placed on the insulation component 100, the flange 320 is arranged around the outer periphery of the insulation component 100. Specifically, the flange 320 and the lower surface of the cover 300 form a receiving groove 330. When the cover 300 is connected to the insulation component 100, the insulation component 100 is located in the receiving groove 330. On the one hand, the insulation component 100 can separate the flange 320 from the cold air in the inner cavity. On the other hand, the flange 320 can also cover the outer periphery of the insulation component 100, preventing the insulation component 100 from being exposed and enhancing the protective effect on the insulation component 100.

[0064] This utility model also proposes a heat pump device 2000, including a side plate 400, a chassis structure 500, a heat exchanger (not shown in the figure), and a top cover assembly 1000 as described in the above embodiments. The side plate 400, the top cover assembly 1000, and the chassis structure 500 together form an inner cavity, which includes an air inlet cavity 410 and an air outlet cavity 420 spaced apart. Specifically, the heat exchanger is disposed in the inner cavity, which can divide the inner cavity into the air inlet cavity 410 and the air outlet cavity 420. Two air vents 120 are provided, one air vent 120 connecting to the air inlet cavity 410 and the other air vent 120 connecting to the air outlet cavity 420. Specifically, the heat pump device 2000 can be a heat pump water heater or a heat pump heating system; this embodiment does not limit this.

[0065] The heat pump device 2000 of this utility model embodiment adopts the top cover assembly 1000 of the above embodiment. By embedding the edge of the grille 200 into the air guide ring 110, the insulation component 100 acts as a heat insulation barrier between the cold air and the cover 300. Based on the assembly of the grille 200, the insulation component 100 separates the cold air flowing through the air outlet 120 from the annular portion 310 sleeved on the outside of the air guide ring 110, thereby blocking the heat transfer channel of the cold air extending from the grille 200 to the cover 300. This prevents the cover 300 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 300. This not only reduces the risk of condensation corroding the shell of the heat pump device 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.

[0066] Since the heat pump device 2000 adopts all the technical solutions of the top cover 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.

[0067] Reference Figure 8 As shown, in this embodiment of the present invention, the heat pump device 2000 includes a duct 600, which is inserted into the air guide ring 110. Specifically, in this embodiment, two air inlets 120 are provided at intervals, wherein the air inlet 120 communicating with the air inlet cavity 410 is the air inlet 121, and the air inlet 120 communicating with the air outlet cavity 420 is the air outlet 122. Similarly, two ducts 600 are provided, which are respectively inserted into the air inlet 121 and the air outlet 122. It can be understood that, since the air guide ring 110 is located inside the annular portion 310, the duct 600 in this embodiment can be inserted into the air inlet 120, and the annular portion 310 and the duct 600 are separated by the air guide ring 110.
