[0036] 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.
[0037] 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.

[0038] 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.
[0039] 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.
[0040] In related technologies, the fan assembly generally adopts an integrated modular design, which is fixed inside the cavity of the casing-type heat pump equipment to drive air circulation. The heat pump equipment is usually placed indoors and exchanges air with the outside through air ducts. Specifically, when the fan is running, outdoor air is drawn into the casing for heat exchange, and then discharged outdoors.
[0041] In cold environments, heat pump units draw in cold outdoor air as a low-temperature heat source to heat the water. Because the cold air continuously flows through the duct, the fan assembly remains at a low temperature, while the housing is closer to the warm indoor temperature. This temperature difference can cause moisture from the air inside the fan assembly to condense on the housing surface when it comes into direct contact with the housing due to vibration or other unforeseen circumstances. This condensation buildup can easily damage electronic components and leak out through gaps in the housing, leading to water accumulation on the heat pump's heat exchanger, increasing the user's cleaning burden and severely impacting the user experience.
[0042] To address the aforementioned problems, some embodiments of this utility model propose a heat pump device 1000, suitable for hot water heating systems. This device can block heat transfer between the exhaust duct 221 and the inner wall of the housing 100, reducing the risk of condensation on the inner wall of the housing 100. See details below. Figures 1 to 9 The heat pump device 1000 is described below.
[0043] Reference Figure 1 As shown, in this embodiment of the present invention, the heat pump device 1000 includes a housing 100, a fan assembly 200, and functional components such as a first heat exchanger 300, a second heat exchanger, and a compressor. The housing 100 has an internal cavity 110, within which the fan assembly 200, heat exchangers, and compressor are installed. In this embodiment, reference is made to... Figure 2 As shown, the fan assembly 200 includes a duct housing 210, which divides the inner cavity 110 of the housing 100 into an air inlet cavity 111 and an air outlet cavity 112. Components such as a compressor, a first heat exchanger 300, and a second heat exchanger are installed inside the air inlet cavity 111. The first heat exchanger 300 is vertically arranged along the height direction of the housing 100 and covers the side of the duct housing 210 facing away from the air outlet cavity 112.
[0044] Continue to refer to Figure 1 As shown in this embodiment of the invention, the housing 100 includes a chassis 130, side panels 140, and a top cover 120. The top cover 120 and the chassis 130 are respectively connected to opposite ends of the side panels 140. The side panels 140, the top cover 120, and the chassis 130 together form an inner cavity 110. The air duct shell 210 is fixedly connected to the chassis 130. The top cover 120 is provided with an air inlet 121 and an air outlet 122. The air inlet 121 communicates with the air inlet cavity 111, and the air outlet 241 communicates with the air outlet cavity 112. The air inlet 121 and the air outlet 241 are respectively connected to the external environment through air ducts. The interior of the duct housing 210 has a duct 211 for accommodating the fan 242. When the fan 242 is running, outside air is drawn into the air inlet chamber 111. When the airflow enters the air outlet chamber 112 from the air inlet chamber 111, it will pass through the first evaporator for heat exchange. The airflow flowing through the first evaporator will enter the duct 211 and be discharged from the exhaust port 122.
[0045] Considering that condensation will occur when the low-temperature air duct shell 210 comes into contact with the warm inner wall of the enclosure 100, refer to Figure 2 and Figure 3As shown, in this embodiment of the present invention, a guide member 220 connected to the air duct shell 210 is also included. Specifically, the guide member 220 is disposed in the air outlet cavity 112. For ease of description, the following description will take the left side of the housing 100 as the air outlet cavity 112 and the right side as the air inlet cavity 111 as an example. In this embodiment, the guide member 220 is located on the left side of the air duct shell 210, the air duct shell 210 and the side plate 140 are spaced apart, and the guide member 220 is disposed between the air duct shell 210 and the side plate 140, thereby separating the air duct shell 210 and the side plate 140.
[0046] Reference Figure 2 As shown in this embodiment of the invention, a first air passage 212 is provided on the right side of the duct shell 210 facing the air inlet cavity 111, i.e., the right side of the duct shell 210. The air guide 220 and the duct shell 210 together define a second air passage 213. Based on this, the airflow passing through the first evaporator will enter the duct 211 through the first air passage 212, and then flow through the second air passage 213 and the exhaust port 122 in sequence, thereby being discharged outdoors. When it is cold outdoors, cold air will continuously flow along the above path, resulting in a low overall temperature of the duct shell 210.
[0047] Therefore, in this embodiment of the utility model, the air guide 220 is made of heat-insulating material. Thus, the air guide 220 can serve as a heat insulation barrier between the air duct shell 210 and the box 100, blocking the heat transfer channel of cold air extending from the air duct shell 210 to the box 100, preventing the box 100 from being affected by two types of air with large temperature differences at the same time, thereby reducing the risk of condensation on the surface of the box 100.
[0048] Specifically, refer to Figure 1 and Figure 3 As shown, in this embodiment of the invention, the air duct housing 210 includes a support 230 and a detachable volute 240. The support 230 is vertically arranged along the height direction of the housing 100, thereby dividing the inner cavity 110 into an air inlet cavity 111 and an air outlet cavity 112. A first air passage 212 is formed on the end face of the support 230 facing the air inlet cavity 111, and a second air passage 213 is formed by the support 230 and the air guide 220 working together. The air duct 211 is formed inside the volute 240. An air inlet (not shown in the figure) is provided on one side of the volute 240 along its axial direction, and an air outlet 241 is provided on the upper side of the volute 240. The air inlet and the air outlet 241 are respectively connected to the air duct 211. In this embodiment, the air inlet and the first air passage 212 are opposite to and connected to each other, and the air outlet 241 is connected to the second air passage 213. The volute 240 is slidably connected to the bracket 230, so the volute 240 can be moved into or out of the air outlet cavity 112, which improves the assembly and disassembly efficiency of the volute 240.
[0049] Understandably, in one example, the volute 240 is made of insulating material. Based on this, the air guide 220 only needs to separate the support 230 from the housing 100. Specifically, the air guide 220 is connected to the support 230 and together defines the exhaust channel 221, located at the outlet of the air duct 211, used to exhaust the airflow within the air duct 211. The air guide 220 protrudes towards the inner wall of the housing 100, which is arranged opposite to the volute 240. For example, the air guide 220 protrudes from the support 230 towards the left side plate of the housing 100, thus being horizontally positioned between the air duct housing 210 and the inner wall of the housing 100, separating the volute 240, support 230, and the inner wall of the housing 100, thereby blocking heat transfer between the exhaust channel 221 and the inner wall of the housing 100.
[0050] Reference Figure 4 As shown, in this embodiment of the present invention, the bracket 230 includes a partition plate 231 and a mounting base 232. The partition plate 231 extends along the height direction of the housing 100 and is located between the air inlet chamber 111 and the air outlet chamber 112. A first air passage 212 is disposed on the side wall of the partition plate 231. The partition plate 231 and the volute 240 are arranged sequentially in the left-right direction, so that one end of the first air passage 212 faces the first heat exchanger 300 and the other end faces the air inlet. In this embodiment, the mounting base 232 is suspended above the volute 240, and its right side is fixedly connected to the upper half of the partition plate 231. Therefore, the mounting base 232 is located between the exhaust port 122 and the air outlet 241. In one example, the mounting base 232 and the partition plate 231 are made by integral injection molding, making the bracket 230 an integral structure and improving the stability of the bracket 230.
[0051] Reference Figure 5 and Figure 6 As shown in this embodiment of the present invention, in order to achieve the connection between the exhaust port 122 and the air outlet 241, the air guide 220 and the middle partition 231 surround the side wall of the air outlet cavity 112 to form an exhaust channel 221. The exhaust channel 221 extends from bottom to top, with one end being a second air passage 213 and the other end being a through hole 2324 provided on the mounting base 232. The through hole 2324 is opposite to and communicates with the air outlet 241. Specifically, the upper end of the air guide 220 and the upper end of the middle partition 231 surround to form the second air passage 213, and the mounting base 232 is provided with a through hole 2324 opposite to the air outlet 241.
[0052] Reference Figure 3 and Figure 4As shown, in this embodiment of the present invention, the upper side of the mounting base 232 is provided with a mounting groove 2321 that matches the air guide 220, so as to facilitate the insertion of the air guide 220 into the mounting groove 2321. It should be noted that the mounting base 232 and the air guide 220 can be fixed by fasteners or by adhesive bonding, etc. In this embodiment, the opening of the mounting groove 2321 faces upward. Based on this, when assembling the fan assembly 200, the air guide 220 can be inserted into the mounting groove 2321 from top to bottom, thereby completing the assembly of the air guide 220.
[0053] In one example, the air guide 220 is made of polyurethane foam insulation material, which has a low thermal conductivity and can serve as insulation. Furthermore, the foam has a certain degree of elastic deformation capability; therefore, the air guide 220 can be fixed to the mounting groove 2321 using an interference fit. Specifically, during installation, the air guide 220 can generate radial clamping force through elastic deformation, thereby forming a stable connection with the mounting groove 2321.
[0054] It should be noted that in this embodiment of the utility model, the air guide 220 is inserted into the mounting groove 2321. Without affecting the movement of the volute 240 into or out of the air outlet cavity 112 in the front-back direction, it separates the inner wall of the box 100 from the middle partition 231, thereby blocking the heat transfer between the cold air in the middle partition 231 and the exhaust channel 221 and the inner wall of the box 100.
[0055] Specifically, refer to Figure 4 and Figure 5 As shown, in this embodiment of the present invention, the mounting base 232 includes a base plate 2322 and a baffle 2323. The right end of the base plate 2322 is fixedly connected to the middle partition plate 231, and the entire base plate is horizontally positioned on the upper side of the volute 240. It can be understood that in this embodiment, the axial direction of the volute 240 is consistent with the left-right direction. Based on this, the extension direction of the base plate 2322 is consistent with the horizontal direction, forming a platform suitable for supporting the air guide 220. The through hole 2324 penetrates the chassis 130 along the height direction of the housing 100, thereby connecting the exhaust channel 221 and the air outlet 241 respectively.
[0056] Reference Figure 5 and Figure 7As shown, in this embodiment of the present invention, the base plate 2322 is generally rectangular, and the baffle 2323 extends circumferentially along the base plate 2322 and is connected to the outer periphery of the chassis 130. Specifically, the baffle 2323 is integrally formed with the base plate 2322, and the baffle 2323 protrudes upward from the upper end surface of the base plate 2322. The baffle 2323 is disposed on the two short sides and the long side between the two short sides of the base plate 2322, and the long side is spaced apart from the middle partition 231, thereby forming a continuous bending structure. Through this three-sided surrounding bending structure, the baffle 2323 and the middle partition 231 cooperate to define an upward-opening mounting groove 2321.
[0057] Reference Figure 7 As shown, in this embodiment of the present invention, the lower end face of the base plate 2322 is slidably engaged with the upper end of the volute 240. Based on this, the lower end face of the base plate 2322 is inclined upward from back to front, thereby increasing the space between the front side of the base plate 2322 and the chassis 130. This facilitates the volute 240 to move forward and detach from the air outlet cavity 112, and to be inserted from the front into the installation space defined between the mounting base 232, the middle partition 231, the side plate 140 and the chassis 130, thereby improving the disassembly and assembly efficiency of the volute 240.
[0058] Reference Figure 3 and Figure 7 As shown in this embodiment of the invention, along the height direction of the housing 100, the air guide 220 is divided into two sections. The outer diameter of the first section located on the upper side is larger than the outer diameter of the second section located on the lower side. The second section is inserted into the mounting groove 2321, while the first section serves to separate the side plate 140 and the middle partition plate 231. Specifically, the lower half of the outer peripheral wall of the air guide 220 is bent inward to form a stepped portion 222. The stepped portion 222 includes a first wall surface 2221 and a second wall surface 2222. The first wall surface 2221 extends vertically, and the second wall surface 2222 extends horizontally, thereby forming a stepped portion 222.
[0059] Continue to refer to Figure 7As shown in this embodiment of the present invention, when the air guide 220 is inserted into the mounting groove 2321, the baffle 2323 is arranged around the outer side of the first wall surface 2221, which limits the first wall surface 2221 and prevents the air guide 220 from shifting within the mounting groove 2321. This enhances the connection stability between the air guide 220 and the partition plate 231, ensuring the integrity and airtightness of the exhaust channel 221. Simultaneously, the top of the baffle 2323 abuts against the second wall surface 2222, keeping the outer peripheral wall of the air guide 220 flush with the outer peripheral wall of the baffle 2323. This improves the overall integrity of the fan assembly 200 and ensures that the air guide 220 can abut against the inner wall of the side plate 140, preventing the partition plate 231 from contacting the side plate 140 and causing cold air transfer, effectively avoiding condensation on the side plate 140 due to temperature differences.
[0060] Reference Figure 3 and Figure 8 As shown, in this embodiment of the invention, the surface of the air guide 220 facing the partition 231 is a first arc surface 223, and conversely, the surface of the partition 231 facing the air guide 220 is a second arc surface 2312. In this embodiment, when the air guide 220 is inserted into the mounting groove 2321, the two ends of the first arc surface 223 and the two ends of the second arc surface 2312 are connected to each other, thereby forming an exhaust channel 221, allowing airflow to flow smoothly along the exhaust channel 221.
[0061] Reference Figure 3 and Figure 7 As shown in this embodiment of the invention, at least two first positioning ribs 2325 are provided on the upper surface of the base plate 2322, and the at least two first positioning ribs 2325 are respectively provided on both sides of the through hole 2324. Specifically, the following description takes the example of having three first positioning ribs 2325. In this embodiment, one first positioning rib 2325 is provided on the rear side of the through hole 2324, and two first positioning ribs 2325 are provided at intervals on the front side of the through hole 2324. The first positioning ribs 2325 extend in the left-right direction.
[0062] Correspondingly, the lower end face of the air guide 220 is provided with three first positioning grooves 224 at intervals. These three first positioning grooves 224 correspond one-to-one with three first positioning ribs 2325. When the air guide 220 is inserted into the mounting groove 2321, the first positioning ribs 2325 insert into the first positioning grooves 224 to achieve positioning engagement. It can be understood that when assembling the air guide 220, the first positioning ribs 2325 serve a positioning function, facilitating the alignment of the air guide 220 with the air guide groove. In particular, the asymmetrical arrangement of the first positioning ribs 2325 on the front and rear sides of the through hole 2324 provides precise guidance, allowing for quick identification of the air guide 220's front-to-back direction and avoiding directional errors during assembly. Furthermore, the first positioning ribs 2325 protrude upwards from the upper end face of the base plate 2322, serving as a guide when the air guide 220 is inserted, improving the installation efficiency of the air guide 220.
[0063] Reference Figure 5 and Figure 8 As shown in this embodiment of the invention, a second positioning rib 2311 is provided on the side of the partition plate 231 facing the mounting groove 2321. The second positioning rib 2311 is located on one side of the second arc surface 2312. In this embodiment, there may be one, two, three, etc., of the second positioning rib 2311, and this embodiment does not limit the number of ribs. Correspondingly, a second positioning groove 225 is provided on the side wall of the air guide 220. When the air guide 220 is inserted into the mounting groove 2321, the second positioning rib 2311 is inserted into the second positioning groove 225 to achieve positioning and engagement, thus playing a role in limiting and positioning.
[0064] Reference Figure 7 and Figure 8 As shown, in this embodiment of the present invention, the upper end surface of the air guide 220 protrudes upward to form a surrounding edge 226, which is generally arc-shaped and extends circumferentially along the second air passage 213. Correspondingly, the upper end surface of the partition plate 231 is provided with a downwardly recessed sealing groove 2313, which is an arc-shaped groove and extends circumferentially along the second air passage 213. Specifically, the surrounding edge 226 and the sealing groove 2313 are respectively arranged around the outer side of the second air passage 213. The surrounding edge 226 is located outside the first arc surface 223, while the sealing groove 2313 is located outside the second arc surface 2312.
[0065] In this embodiment of the invention, the lower end of the top cover 120 protrudes downward to form an annular sealing portion 123. A portion of the sealing portion 123 is located on the upper side of the air guide 220, and another portion is located on the upper side of the partition plate 231. The portion located on the upper side of the air guide 220 abuts against the upper end face of the air guide 220 and is disposed around the outer side of the surrounding edge 226, while the portion located on the upper side of the partition plate 231 is inserted into the sealing groove 2313. It is understood that both the fit between the sealing portion 123 and the surrounding edge 226, and the fit between the sealing portion 123 and the inner wall of the sealing groove 2313, form a curved sealing path, thereby improving the tightness of the connection between the exhaust port 122 and the second air outlet 213, effectively preventing airflow leakage, and enhancing the airtightness of the fit between the top cover 120 and the fan assembly 200.

Specifically, the first sealing ring 270 is circular, and a first annular groove 250 is provided on the surface of the partition plate 231. The first sealing ring 270 is arranged circumferentially along the first air outlet 212. The first annular groove 250 is circular and matches the first sealing ring 270. The first sealing ring 270 is embedded in the first annular groove 250. The first sealing ring 270 and the first annular groove 250 can be fixed by interference fit, adhesive, or other means. The first annular groove 250 plays an effective limiting role for the first sealing ring 270.
[0067] Continue to refer to Figure 9 As shown in this embodiment of the present invention, a second sealing ring 280 is provided on the side of the mounting base 232 facing the volute 240. The second sealing ring 280 is square. A second annular groove 260 is provided on the end face of the base plate 2322 facing the volute 240. The second sealing ring 280 is arranged circumferentially along the through hole 2324. The second annular groove 260 is square and matches the second sealing ring 280. The second sealing ring 280 is embedded in the second annular groove 260. The second sealing ring 280 and the second annular groove 260 can be fixed by interference fit, adhesive, or other means. The second annular groove 260 plays an effective limiting role for the second sealing ring 280.
[0068] Understandably, a portion of the first sealing ring 270 is connected within the first annular groove 250, while the other portion protrudes from the first annular groove 250, ensuring that the first sealing ring 270 can abut against the surface of the volute 240. It should be noted that the diameter of the first annular groove 250 is larger than the diameter of the air inlet; that is, the diameter of the first sealing ring 270 is larger than the diameter of the air inlet, ensuring that the first sealing ring 270 can abut against the surface of the volute 240 and surround the air inlet, forming an effective sealing structure. A portion of the second sealing ring 280 is connected within the second annular groove 260, while the other portion protrudes from the second annular groove 260, ensuring that the second sealing ring 280 can abut against the end face of the air outlet 241, forming an effective sealing structure.
[0069] An embodiment of this utility model also proposes a hot water heating system, including the heat pump device 1000 described in the above embodiment. Specifically, the heat pump device 1000 can be connected to external devices such as a gas-fired wall-hung boiler, an electric heater, or a water tank to form a hot water heating system, providing users with domestic hot water and heating hot water.
[0070] The hot water heating system of this embodiment adopts the heat pump device 1000 of the above embodiment. An air duct 211 is configured inside the air duct housing 210. A first air outlet 212 communicating with the air duct 211 is provided on one side of the air duct housing 210, thereby introducing air from the inner cavity 110 into the air duct 211. An air guide 220 is connected to the air duct housing 210 and together defines a second air outlet 213 communicating with the air duct 211, thereby venting air from the air duct 211. The air guide 220 is disposed between the inner wall of the housing 100 and the air duct housing 210, thereby directing the air from the air duct housing 210 into the air duct 211. The inner wall of the duct shell 210 and the inner wall of the housing 100 are separated to prevent direct contact between the duct shell 210 and the inner wall of the housing 100. The air guide 220 is made of heat-insulating material and serves as a heat insulation barrier between the duct shell 210 and the housing 100. It blocks the heat transfer channel that extends from the duct shell 210 to the housing 100, and prevents the housing 100 from being affected by two types of air with large temperature differences at the same time. This reduces the risk of condensation on the surface of the housing 100 and the risk of failure of the heat pump equipment 1000, thereby improving the stability and reliability of the hot water heating system.
[0071] Since the hot water heating system adopts all the technical solutions of the heat pump equipment 1000 in the above embodiments, it has at least all the beneficial effects brought about by the technical solutions in the above embodiments, which will not be repeated here.
[0072] Of course, this utility model 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 utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
