[0040] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0042] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present utility model. Instead, they are only examples of devices and methods consistent with some aspects of the present utility model as detailed in the attached claims.

[0043] In the description of the present utility model, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, in the description of the present utility model, unless otherwise specified, "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previously associated objects are in an "or" relationship.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0045] An embodiment of the present application proposes an outdoor unit and a HVAC system, which includes an outdoor unit and an indoor unit, wherein the outdoor unit and the indoor unit are connected by a pipeline, and a working medium for heat exchange circulates in the outdoor unit and the indoor unit through the pipeline.

[0046] The indoor unit may include components such as a heat exchanger, a water pump, an electric heating device, and an energy storage water tank, which are connected by water pipes to form a water circulation flow path. The heat exchanger has two inlets and two outlets, one set of interconnected inlets and outlets for the refrigerant to pass through, and the other set of interconnected inlets and outlets for the water medium to pass through. When the water medium flows through the heat exchanger, the refrigerant in the heat exchanger contacts the water, thereby heating the water. The water pump provides power for the water circulation. The electric heating device can reheat the water heated by the heat exchanger and transport it to the energy storage water tank through a water pipe, thereby meeting the user's heating needs.

[0047] The outdoor unit may include components such as an evaporator, a compressor, a heat exchanger, and an expansion valve, which are connected in a circular manner through a refrigerant pipe. When the HVAC equipment is working, the refrigerant in the evaporator absorbs heat from the air and becomes a high-temperature, low-pressure gas; the high-temperature gas is then compressed by the compressor, so that the refrigerant forms a high-temperature, high-pressure liquid; the high-temperature, high-pressure liquid exchanges heat with the water in the water circulation circuit through the heat exchanger, so that the water temperature in the water circulation circuit rises, and the refrigerant becomes a low-temperature, high-pressure liquid; the low-temperature, high-pressure liquid passes through the expansion valve and becomes a low-temperature, low-pressure gas, and then circulates to the evaporator again, thus completing the refrigerant circulation process.

[0048] See also Figure 1 , and the outdoor unit also includes a shell assembly 10, a main control board (not shown in the figure) and a wire controller 20. The shell assembly 10 includes a shell 100. The shell 100 has an installation cavity 11 formed inside, which can be loaded with the above-mentioned main control board, wire controller 20, evaporator, compressor, heat exchanger, expansion valve and other components. The specific shape of the shell 100 is not limited here. Designers can make reasonable designs according to actual needs. For example, the shell 100 can be but not limited to a flat rectangular structure. Of course, the specific preparation material of the shell is not limited here. Designers can make reasonable choices according to actual needs. For example, the preparation material of the shell 100 can be but not limited to plastic or metal. And it can be understood that for fan equipment with different specific forms, the design of the shape of the shell 100 and the selection of preparation materials are also different.

[0049] The housing assembly 10 is provided with a receiving cavity 12 on its outer wall, and the housing assembly 10 is also provided with a wiring hole 40 connecting the installation cavity 11 and the receiving cavity 12. The wire controller 20 includes a wire controller body 21 and a conductive wire 22. The conductive wire 22 is passed through the wiring hole 40 and includes a connecting section 22a located in the installation cavity 11 and a redundant section 22b connected to the connecting section 22a. The connecting section 22a is electrically connected to the main control board, and the redundant section 22b is electrically connected to the wire controller body 21. The wire controller 20 has a storage state and a use state. In the storage state, the wire controller body 21 and the redundant section 22b can be stored in the above-mentioned receiving cavity 12. In the use state, the wire controller body 21 can be taken out of the receiving cavity 12, and the redundant section 22b can be at least partially dragged out of the receiving cavity 12.

[0050] It can be understood that when the wire controller 20 is in the storage state, the wire controller body 21 and the conductive wire 22 are both stored in the receiving cavity 12, so that the wire controller body 21 and the conductive wire 22 can be protected, and when in use, since the conductive wire 22 is provided with a redundant section 22b, the wire controller body 21 can be taken out of the receiving cavity 12 for use. Compared with the prior art, in which the wire controller body 21 is fixed on the outer wall of the housing 100, in the embodiment of the present application, when taking out the wire controller body 21, the user can stand throughout the whole process, without squatting or sitting down to adjust the wire controller body 21, and the operation is more convenient.

[0051] The receiving cavity 12 formed on the outer wall of the housing assembly 10 may have various forms, see Figure 2 and Figure 3 For example, the receiving cavity 12 can be provided on the outer wall of the housing 100. Specifically, the outer wall of the housing 100 can be recessed to form a receiving groove 110. The housing assembly 10 further includes a cover body, which is movably connected to the housing 100 and covers the notch of the receiving groove 110 to form the receiving cavity 12. In this embodiment, a wiring hole 40 is provided at a position of the housing 100 corresponding to the receiving groove 110.

[0052] It should be noted that the connection between the cover and the housing 100 can be that one side of the cover is rotatably connected to the housing 100, and the receiving cavity 12 can be switched between the storage state and the open state by flipping the cover. The connection between the cover and the housing 100 can also be a sliding connection, and the receiving cavity 12 can be opened or closed by sliding the cover.

[0053] In some embodiments, see Figure 1 and Figure 4 The housing assembly 10 may further include a storage box 200, which is mounted on the outer wall of the housing 100. The storage box 200 includes a box body 210 and a box cover 220, wherein the box body 210 has an open receiving groove, which is movably connected to the box body 210 and cooperates with the box body 210 to form the above-mentioned receiving cavity 12, and the box body 210 is fixed on the outer wall of the housing 100. In this embodiment, both the box body 210 and the housing 100 are provided with a wiring hole 40.

[0054] In some connection modes, the box cover 220 and the box body 210 are rotatably connected so as to be flipped open relative to the box body 210. Specifically, one end of the box cover 220 is rotatably connected to one end of the box body 210 via a rotating shaft, so that when the free end of the box cover 220 is flipped, the receiving cavity 12 can be opened or closed. Furthermore, the top of the box cover 220 can be rotatably connected to the top of the box body 210. With such a configuration, when the user needs to use the wired controller 20, the user can easily flip the box cover 220 to access the wired controller 20 in the receiving cavity 12 without the need for additional opening or disassembly steps, and the operation is relatively simple.

[0055] In order to improve the stability of the box body 210 and the box cover 220 when they are relatively fixed, so as to improve the ability of the storage box 200 to protect the wire controller 20 in the storage state, a first buckle portion is provided at one end of the box cover 220 away from the rotating connection, and a second buckle portion is provided at one end of the box body 210 away from the rotating connection. The box body 210 and the box cover 220 can be relatively fixed firmly through the buckle connection of the first buckle portion and the second buckle portion. The first buckle portion and the second buckle portion can be two mutually cooperating hooks, or one can be a hook and the other can be a slot. Here, the present application does not limit the specific form of the first buckle portion and the second buckle portion. Of course, in other embodiments, the box body 210 and the box cover 220 can also be relatively fixed by screws, bolts and other threaded fasteners. When the wire controller 20 needs to be used, the threaded fasteners can be removed using tools.

[0056] Furthermore, in order to facilitate the installation of the storage box 200 on the outer wall of the housing 100, a mounting groove 130 is formed on the outer wall of the housing 100, and the box body 210 is at least partially embedded in the mounting groove 130. In this way, the mounting groove 130 can provide additional support, so that the storage box 200 is more firmly installed on the outer wall of the housing 100, and is not easy to loosen or shake. Moreover, the storage box 200 is partially embedded in the mounting groove 130, which can effectively save space, and the storage box 200 will not excessively protrude from the outer wall of the housing 100, and the overall appearance is more beautiful and neat.

[0057] Based on the outdoor unit of the embodiment of the present application, by providing the conductive wire 22 with a redundant section 22b, when the wire controller 20 needs to be used, the wire controller body 21 can be taken out of the receiving chamber 12 for use. Compared with the prior art, in which the wire controller body 21 is fixed on the outer wall of the housing 100, in the embodiment of the present application, when taking out the wire controller body 21, the user can stand throughout the whole process without squatting or sitting down to adjust the wire controller body 21, and the operation is more convenient. Moreover, for the user group who does not know how to "Asian squat", the present application can make the user more comfortable and convenient during use, improve the user's overall experience, and enhance the user's satisfaction with the product. Moreover, when the wire controller 20 is not needed, the wire controller body 21 and the conductive wire 22 can be stored in the receiving chamber 12 to protect the wire controller body 21 and the conductive wire 22.

[0058] In order to facilitate the arrangement of the conductive wires 22 in the storage state, the embodiment of the present application also includes a winding structure 30, and the winding structure 30 is arranged on the box body 210. Among them, in the storage state, the redundant segment 22b can be wound on the winding structure 30. In this way, when the wire controller 20 is in the storage state, the redundant segment 22b can be wound on the winding structure 30, effectively utilizing the internal space of the box body 210, which can not only save storage space, but also keep the wires neat and orderly, avoid the entanglement and confusion of the wires, and improve the overall aesthetics of the product. When the wire controller 20 needs to be used, the user can easily untie the redundant segment 22b wound on the winding structure 30, take out the wire controller 20 and use it, which is easy to operate and improves the user's convenience.

[0059] In some embodiments, please refer to Figure 4 and Figure 6 The winding structure 30 includes a winding rib 30a, which surrounds the wiring hole 40 and has a wire passing opening 33. In the stored state, the redundant section 22b can pass through the wire passing opening 33 and be wound around the outer peripheral side of the winding rib 30a. In this way, the conductive wire 22 can be effectively fixed, avoiding the loosening or falling of the wire in the stored state, and maintaining the stability and reliability of the wire.

[0060] It can be understood that, since the winding rib 30a surrounds the wiring hole 40, and there is a step difference between the winding rib 30a and the wiring hole 40, when the wire-passing opening 33 is not provided, the conductive wire 22 needs to pass through the winding rib 30a before it can be wound around the outer peripheral side of the winding rib 30a after extending from the wiring hole 40, which easily leads to poor stability of the fixing of the conductive wire 22. However, the present application provides a wire-passing opening 33, and the conductive wire 22 can be wound around the outer peripheral side of the winding rib 30a through the wire-passing opening 33, which can effectively avoid the step difference problem between the winding rib 30a and the wiring hole 40.

[0061] Of course, in some other embodiments, the winding rib 30a can be a straight structure or a dot matrix structure or other structural forms that are not arranged around the wiring hole 40, so that there is no need to set the wire opening 33, and the conductive wire can also be conveniently wound around the outer peripheral side of the winding rib 30a. Here, the present application does not limit the specific form of the winding rib 30a.

[0062] In some structural forms, the winding rib 30a includes a first rib 31 and at least one second rib 32 arranged at intervals, the first rib 31 is arranged around the wiring hole 40 and defines a wire passing opening 33 at both ends, the second rib 32 is arranged on the outside of the second rib 32, and a wiring channel 34 is defined between the first rib 31 and the second rib 32. In this arrangement, the wiring channel 34 is defined between the first rib 31 and the second rib 32, so that the conductive wire 22 can pass through in an orderly manner along a specific path, reducing the entanglement and confusion between the conductive wires 22, and maintaining the neatness and maintainability of the line.

[0063] At least one of the first rib 31 and the second rib 32 is provided with a wire-holding protrusion 35 located on the inner wall of the wiring channel 34. The wire-holding protrusion 35 can effectively fix the position of the wire, making it difficult to move or swing, which is conducive to maintaining the stability of the line and preventing the conductive wire 22 from loosening or falling off, thereby reducing the possibility of equipment failure.

[0064] In order to improve the stability of the conductive wire 22 at the wire opening 33, at least one second rib 32 is arranged at the wire opening 33. Specifically, the embodiment of the present application can enhance the support and fixation of the conductive wire 22 at the position by arranging the second rib 32 at the wire opening 33. In this way, the conductive wire 22 can be prevented from shaking or loosening at the wire opening 33, thereby improving the stability and reliability of the line.

[0065] In some embodiments, see Figure 7The winding rib 30a includes a winding portion 30a1 and a limiting portion 30a2. The winding portion 30a1 is connected to the box body 210. The limiting portion 30a2 is connected to the side of the winding portion 30a1 away from the box body 210, and the box body 210, the winding portion 30a1 and the limiting portion 30a2 cooperate to define a wiring groove 30a3. The limiting portion 30a2 is connected to the side of the winding portion 30a1 away from the box body 210, and cooperates with the box body 210. The box body 210, the winding portion 30a1 and the limiting portion 30a2 cooperate to define the wiring groove 30a3, making wiring more convenient. The setting of the wiring groove 30a3 can effectively fix the conductive wire 22, avoid the loosening or confusion of the wire during use, keep the line neat and orderly, and improve the maintainability and reliability of the equipment. The box body 210, the winding portion 30a1 and the limiting portion 30a2 may be integrally formed components, so that the winding structure 30 and the box body 210 have good integrity.

[0066] The winding rib 30a includes a third rib 37 and a fourth rib 38, and the third rib 37 and the fourth rib 38 are relatively spaced apart on the outside of the wiring hole 40, and two wire passing openings 33 are defined between the third rib 37 and the fourth rib 38. By relatively spacing the third rib 37 and the fourth rib 38, two wire passing openings 33 can be formed, so that the user can flexibly arrange the winding method of the conductive wire 22 according to needs. In this way, it is convenient for the user to choose different paths to wind the wire to meet different usage requirements. The relative spacing of the third rib 37 and the fourth rib 38 can provide more winding areas, so that the conductive wire 22 can be more firmly wound on the winding rib 30a, thereby enhancing the fixity and stability of the wire and avoiding the loosening or falling off of the wire during movement or vibration.

[0067] In some embodiments of the present application, the winding ribs 30a discussed above and below can be arc-shaped structures. The arc-shaped winding ribs 30a can disperse the concentrated points of force on the guide wire. Compared with the winding ribs 30a with angled structures such as rectangular structures and triangles, the arc-shaped winding ribs 30a can reduce the stress concentration phenomenon of the conductive wire 22 at the connection point or bend, thereby reducing the mechanical stress of the conductive wire 22, extending the service life of the wire, and reducing the breakage or damage caused by stress concentration.

[0068] In order to facilitate the installation of the storage box 200 and the shell 100, a first positioning boss 120 is provided on the outer wall of the shell 100, and the box body 210 includes a bottom plate and a second positioning boss 211 connected to the bottom plate. The second positioning boss 211 is protruded in the direction away from the shell 100, and a positioning groove opened toward the shell 100 is formed in the second positioning boss 211, and the first positioning boss 120 is at least partially embedded in the positioning groove. Among them, the winding rib 30a is arranged around the second positioning boss 211, and the wiring hole 40 on the shell 100 is arranged on the first positioning boss 120. Specifically, during installation, the first positioning boss 120 is aligned with the positioning groove and embedded in the positioning groove, and then the box body 210 and the shell 100 are relatively fixed using fasteners such as screws and bolts, so that the installation operation is simple.

[0069] Furthermore, part of the wiring hole 40 on the box body 210 is located on the bottom plate, and the other part is located on the second positioning boss 211. Since the wiring hole 40 is partially located on the bottom plate, it can be more convenient to install, and there is no need to consider the height of the second positioning boss 211 too much. It is only necessary to align the bottom plate with the housing 100, which simplifies the installation process and improves the installation efficiency. Of course, the wiring hole 40 on the box body 210 is located on the second positioning boss 211. It should be noted that in this embodiment, the height of the second positioning boss 211 is lower than the height of the winding rib 30a compared to the bottom plate. It is understandable that if the height of the second positioning boss 211 is higher than the winding rib 30a, the conductive wire 22 will be hindered by the second positioning boss 211 when routing, which increases the difficulty of routing.

[0070] Please refer to Figures 4 to 8 The wire controller body 21 is provided with a hook 36, the box body 210 is provided with a hook 212, and the hook 36 is hung on the hook 212. In this way, the wire controller body 21 can be conveniently fixed in the receiving cavity 12 without the need for additional brackets or installation tools.

[0071] In the case where the receiving cavity 12 is formed on the outer wall of the housing 100, the winding structure 30 is disposed on the outer wall of the housing 100 and is located in the receiving groove 110. In the receiving state, the redundant section 22b can be wound around the winding structure 30. In addition, a hook 212 may also be disposed on the outer wall of the housing 100 to facilitate the receiving operation of the wire controller body 21.

[0072] In some other embodiments, the winding structure 30 may also be a wire reel, which can effectively protect the wires from being damaged by external objects. When storing, the wire reel can automatically store the conductive wire 22 without the need for additional winding operations, making it convenient for users to use.
