[0028] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0029] Figures 1 to 3 The heat pump system device 1 in one embodiment of the utility model is shown, including a housing 10, a water tank 20, an outdoor heat exchanger 30 and a pipe connection assembly 40. The housing 10 defines a housing space 11, and the outdoor heat exchanger 30 and the water tank 20 are both arranged in the housing space 11, and the two are arranged adjacent to each other, so as to save space, improve the space utilization rate of the equipment, and realize the miniaturization of the equipment. The water tank 20 is used to accommodate domestic water, and the heat exchanger is used to exchange heat during the refrigerant circulation process, so as to realize the heating of domestic water while cooling or heating. The outdoor heat exchanger 30 is one of the heat exchangers of the heat pump system device 1, and is used for heat exchange. The pipe connection assembly 40 is installed on the housing 10, and is used to connect the water inlet and outlet of the water tank 20 with external equipment to realize the inlet and outlet circulation of water in the water tank 20.

[0030] Specifically, Figure 2 As shown, the water tank 20 includes a water inlet for connecting to a water inlet pipe 41 and a water outlet for connecting to a water outlet pipe 42 , and the pipe connection assembly 40 includes at least one pipe stopper 43 for limiting the water inlet pipe 41 and the water outlet pipe 42 .

[0031] The water inlet pipe 41 and the water outlet pipe 42 are both arranged outside the housing 10. The water inlet pipe 41 is limited on the housing 10 by the pipe stopper 43, and its input end is connected to the water inlet of the water tank 20, and its output end extends to the side of the outdoor heat exchanger 30 away from the water tank 20, and is used to be connected to water delivery equipment (such as an external tap water pipe, etc.) to deliver domestic water to be heated into the water tank 20. The water outlet pipe 42 is installed on the housing 10 by the pipe stopper 43, and its input end is connected to the water outlet of the water tank 20, and its output end extends to the side of the outdoor heat exchanger 30 away from the water tank 20, and is used to be connected to water-using equipment (such as faucets, showers, etc.) to output the domestic hot water heated in the water tank 20.

[0032] like Figure 3 As shown, it should be understood that during the installation of the heat pump system device 1, there is a problem of narrow installation space. For example, when the heat pump system device 1 needs to be installed against a wall (especially in a corner adjacent to two walls), the side of the shell 10 where the outdoor heat exchanger 30 that needs to be radiated is located will be set away from the corner where the two walls are connected to ensure the heat dissipation. However, such a setting method will cause one side of the shell 10 where the water tank 20 adjacent to the outdoor heat exchanger 30 is located to be set against the wall. After the heat pump system device 1 is installed in place, it needs to be connected to external equipment (water delivery equipment, water-using equipment, etc.) through pipes. It is very difficult to connect the water inlet and outlet of the water tank 20 located in the narrow gap between the wall and the shell 10 with the connecting pipes of the external equipment. The limited installation space makes it difficult to connect the pipes.

[0033] The arrangement of the pipe connection assembly 40 can be performed by pre-installing the pipe connection assembly 40 and fixing it relatively to the housing 10 before installing the heat pump system device 1. Since the pipe stopper 43 extends the output ends of the water inlet pipe 41 and the water outlet pipe 42 to the side of the outdoor heat exchanger 30 away from the water tank 20, when the subsequent heat pump system device 1 is installed in place, since the side of the housing 10 close to the outdoor heat exchanger 30 is not set against the wall (or is not in the depth of the slit formed by the housing 10 and the wall), the output ends of the water inlet pipe 41 and the water outlet pipe 42 are not in the depth of the slit formed by the housing 10 and the wall. At this time, the input and output of domestic hot water in the water tank 20 can be realized by directly connecting the connecting pipes of the external equipment to the water inlet pipe 41 and the water outlet pipe 42.

[0034] In this embodiment, the water inlet pipe 41 and the water outlet pipe 42 are both part of the pipe connection assembly 40 in the heat pump system device 1. In some other optional embodiments, the heat pump system device 1 may not include the water inlet pipe 41 and the water outlet pipe 42, and the water inlet pipe 41 and the water outlet pipe 42 may be provided separately, and it is only necessary to ensure that the two ends thereof can be connected to the water inlet / outlet of the water tank 20 and the connecting pipe of the external equipment respectively.

[0035] Read also Figure 1 In this embodiment, the housing 10 is roughly in the shape of a cube, the accommodating space 11 is also in the shape of a cube, the water tank 20 is vertically arranged in the accommodating space 11, and is arranged adjacent to and side by side with the outdoor heat exchanger 30, so that the two are respectively located on the left and right sides of the accommodating space 11. The horizontal cross-section of the outdoor heat exchanger 30 is L-shaped, and the heat pump system device 1 also includes a fan 50, which is arranged in the rectangular space surrounded by the L-shape of the outdoor heat exchanger 30, and is used to assist the outdoor heat exchanger 30 in heat exchange. When heating, the fan 50 is used to extract external air to exchange heat with the outdoor heat exchanger 30, and when cooling, the fan 50 is used to blow out the heat released during the heat exchange process of the outdoor heat exchanger 30. When the heat pump system equipment 1 is installed in place, the two adjacent side walls of the shell 10 close to the water tank 20 (defined as the second side wall 102 and the first side wall 101 respectively) are both set close to the wall (when the heat pump system equipment 1 is installed at the corner where two walls are connected), the side wall of the shell 10 close to the fan 50 (defined as the third side wall 103) needs to be set not close to the wall, the side wall of the L-shaped short side of the shell 10 close to the outdoor heat exchanger 30 (defined as the fourth side wall 104) is not set close to the wall, and the side wall of the L-shaped long side of the shell 10 close to the outdoor heat exchanger 30 (this side wall is the same side wall as one of the two adjacent side walls close to the water tank 20, such as both are the first side wall 101) is set close to the wall.

[0036] At this time, when the pipe connection assembly 40 is pre-installed on the shell 10, and when the heat pump system equipment 1 is installed in place, the output ends of the water inlet pipe 41 and the water outlet pipe 42 extend from the slit between the first side wall 101 and the wall, and the connection pipes with external equipment can be connected quickly and conveniently.

[0037] It should be understood that the “side of the outdoor heat exchanger 30 away from the water tank 20 ” refers to the portion of the wall surface of the fourth side wall 104 , the third side wall 103 or the first side wall 101 corresponding to the end of the outdoor heat exchanger 30 away from the water tank 20 .

[0038] In some embodiments, at least one connection hole is formed on the housing 10 to connect the accommodating space 11 with the outside, and the water inlet pipe 41 and the water outlet pipe 42 are respectively connected to the water inlet and the water outlet through the connection hole. The connection hole and the pipe stopper 43 are both arranged on the same side wall of the housing 10, and the pipe stopper 43 is arranged at the end of one side of the side wall away from the connection hole, thereby achieving that the output ends of the water inlet pipe 41 and the water outlet pipe 42 are not in the slit, and the length of the water inlet pipe 41 and the water outlet pipe 42 can be shortened, and bending between two different side walls can be avoided, thereby reducing the possibility of damage.

[0039] In this embodiment, there are two connection holes, namely, a first connection hole and a second connection hole, wherein the first connection hole corresponds to the water inlet, and the second connection hole corresponds to the water outlet. The first connection hole, the second connection hole and the pipe stopper 43 are all located on the first side wall 101, and the pipe stopper 43 is located at the end of one side of the first side wall 101 away from the first connection hole and the second connection hole. The output ends of the water inlet pipe 41 and the water outlet pipe 42 are both protrudingly arranged on the side of the fourth side wall 104 away from the second side wall 102, extending out of the slit defined by the first side wall 101 and the wall.

[0040] In some other optional embodiments, the number of the connecting holes may also be set to one, so that the water inlet pipe 41 and the water outlet pipe 42 are respectively connected to the water inlet and the water outlet through one connecting hole.

[0041] In some other optional embodiments, the connecting hole and the pipe limiter 43 can also be arranged on different walls respectively. For example, the pipe limiter 43 can be arranged on the third side wall 103 or the fourth side wall 104, so that the output ends of the water inlet pipe 41 and the water outlet pipe 42 are not located between the narrow gap between the shell 10 and the wall.

[0042] In some other optional embodiments, the pipe limiter 43 can also be set at the non-end portion of the first side wall 101. Even in this case, the setting position of the pipe limiter 43 can make the water inlet pipe 41 and the water outlet pipe 42 extend from the side where the water tank 20 is located to the side of the outdoor heat exchanger 30. The output ends of the water inlet pipe 41 and the water outlet pipe 42 are both facing the outlet of the slit, which greatly facilitates the connection of the pipes by the staff.

[0043] like Figure 2As shown, in some embodiments, the water tank 20 includes a box body 21, a water inlet short pipe 22 and a water outlet short pipe 23, wherein the box body 21 is vertically arranged in the accommodating space 11, and the water inlet short pipe 22 and the water outlet short pipe 23 are both arranged on the box body 21, used to define the water inlet and outlet, and are respectively connected to the water inlet pipe 41 and the water outlet pipe 42. The water inlet short pipe 22 is arranged in the first connecting hole, one end of which extends to the outside of the shell 10 and is connected to the water inlet pipe 41, and the water outlet short pipe 23 is arranged in the second connecting pipe 13, one end of which extends to the outside of the shell 10 and is connected to the water outlet pipe 42.

[0044] It should be understood that the water inlet of the water tank 20 is the connection port formed by the end of the water inlet short pipe 22 away from the box body 21, and the water outlet of the water tank 20 is the connection port formed by the end of the water outlet short pipe 23 away from the box body 21.

[0045] The provision of the water inlet short pipe 22 and the water outlet short pipe 23 allows the box body 21 to fill the space on one side of the accommodating space 11 as much as possible. On the premise that the volume of the water tank 20 remains constant, the volume of the accommodating space 11 can be reduced, thereby improving the miniaturization of the heat pump system equipment 1, or on the premise that the volume of the accommodating space 11 remains constant, the volume of the water tank 20 can be expanded as much as possible, thereby increasing the storage capacity of domestic hot water and avoiding the water inlet pipe 41 and the water outlet pipe 42 partially extending into the accommodating space 11 to occupy volume.

[0046] Specifically, the ends of the water inlet short pipe 22 and the water outlet short pipe 23 away from the box body 21 are both provided with threads, and the input ends of the water inlet pipe 41 and the water outlet pipe 42 are also provided with threads. The input ends of the water inlet short pipe 22 and the water inlet pipe 41 are connected by threads, and the water outlet short pipe 23 is connected to the input end of the water outlet pipe 42 by threads, thereby simplifying the convenience of assembly between the water tank 20 and the pipe connection assembly 40.

[0047] It should be understood that the structural setting of the output ends of the water inlet pipe 41 and the water outlet pipe 42 is not limited here, and the output ends can also be connected to the connecting pipes of external equipment by setting a threaded structure, or directly connected to the connecting pipes by welding, gluing, etc., or by setting pipe connecting components to achieve the connection between the two pipes.

[0048] In some embodiments, at least part of the water inlet pipe 41 (water outlet pipe 42) is horizontally extended, and at least part of the horizontally extended part is located at the output end of the water inlet pipe 41 (water outlet pipe 42). In the process of connection, the water inlet pipe 41 and the water outlet pipe 42 can extend a slit in the horizontal direction, so that the opening of the output end is in a horizontal direction, which is convenient for direct connection with the pipeline of the external device.

[0049] Specifically, the level of the output end of the water inlet pipe 41 is equal to or lower than the level of its input end, and the level of the output end of the water outlet pipe 42 is equal to or lower than the level of its input end, so as to facilitate the input and output of domestic water.

[0050] In this embodiment, the horizontal height of the water inlet of the water tank 20 is lower than the horizontal height of the water outlet, so that the water in the water tank 20 can utilize the principle that the density of water decreases with the increase of temperature. The water outlet for outputting hot water is set above the water inlet for inputting cold water, thereby reducing the heat exchange between cold and hot water inside the water tank 20.

[0051] The extending directions of the input ends of the water inlet pipe 41 and the water outlet pipe 42 are perpendicular to the first side wall 101, so as to be connected with the water inlet short pipe 22 and the water outlet short pipe 23 extending from the connection hole of the first side wall 101. The other parts of the water inlet pipe 41 and the water outlet pipe 42 are parallel (or approximately parallel) to the first side wall 101.

[0052] The input end and the output end of the water inlet pipe 41 have the same horizontal height, that is, the water inlet pipe 41 is arranged horizontally. This facilitates the input of cold water and reduces the consumption of kinetic energy of external equipment. The water outlet pipe 42 includes a first pipe section 421 and a second pipe section 422 connected end to end, wherein the first pipe section 421 is arranged obliquely, and its input end is connected to the pipe section perpendicular to the first side wall 101, and the output end is connected to the input end of the second pipe section 422, and the horizontal height of the output end of the first pipe section 421 is lower than the input end. The second pipe section 422 is arranged to extend horizontally, and its output end is the output end of the water outlet pipe 42. The extension method of the water outlet pipe 42 first descending and then horizontally can facilitate the output of domestic hot water in the water tank 20.

[0053] In some other optional embodiments, the first tube segment 421 and the second tube segment 422 may both extend in a horizontal direction.

[0054] The heights of the output ends of the water inlet pipe 41 and the water outlet pipe 42 can be the same or different. In this embodiment, the level of the output end of the water inlet pipe 41 is lower than the level of the output end of the water outlet pipe 42 to avoid cross-entanglement between the two water pipes.

[0055] In some embodiments, the number of the pipe stopper 43 is also two, namely, a first pipe stopper 431 and a second pipe stopper 432. The first pipe stopper 431 is used to fix the water inlet pipe 41 on the housing 10, and the second pipe stopper 432 is used to fix the water outlet pipe 42 on the housing 10. The horizontal height of the first pipe stopper 431 is equal to or lower than the horizontal height of the water inlet, and the horizontal height of the second pipe stopper 432 is equal to or lower than the horizontal height of the water outlet, so as to limit the setting positions of the water inlet pipe 41 and the water outlet pipe 42, and ensure the circulation of water in the pipe.

[0056] In this embodiment, the horizontal height of the first pipe stopper 431 is lower than the horizontal height of the second pipe stopper 432, and the first pipe stopper 431 and the second pipe stopper 432 are arranged at intervals. The horizontal height of the second pipe stopper 432 is lower than the horizontal height of the water outlet and is equal to the horizontal height of the output end of the water outlet pipe 42. The horizontal height of the first pipe stopper 431 is equal to the horizontal height of the water inlet and is equal to the horizontal height of the output end of the water inlet pipe 41.

[0057] In one embodiment, the first pipe stopper 431 and the second pipe stopper 432 are both in a "J"-shaped structure, and both ends of the "J"-shaped structure are connected to the side wall of the housing 10 by bolts, welding, etc., and the other parts of the "J"-shaped structure define a clearance hole with the side wall of the housing 10, and the water inlet pipe 41 and the water outlet pipe 42 are respectively inserted into the clearance holes defined by the first pipe stopper 431 and the second pipe stopper 432 and the side wall of the housing 10. At the same time, the first pipe stopper 431 and the second pipe stopper 432 are both arranged in a vertical direction, so that the two ends of the "J"-shaped structure of each pipe stopper 43 are connected parallel to the vertical axis of the housing 10, so that the axis of the defined clearance hole extends in the horizontal direction, thereby making the output ends of the water inlet pipe 41 and the water outlet pipe 42 extend horizontally.

[0058] For example Figure 2 As shown, in this embodiment, the water inlet pipe 41 and the water outlet pipe 42 are both circular tube structures, and the clearance holes defined by the first pipe limiter 431 and the second pipe limiter 432 and the shell 10 are also arched structures, so that the water inlet pipe 41 and the water outlet pipe 42 can be inserted into the clearance holes.

[0059] In some other optional embodiments, the first pipe stopper 431 and the second pipe stopper 432 can be arranged adjacent to each other, so that the output ends of the water inlet pipe 41 and the water outlet pipe 42 extend side by side. The first pipe stopper 431 and the second pipe stopper 432 can also be arranged as an integrated structure (i.e., only one pipe stopper 43 is arranged), and two clearance holes or one clearance hole are formed on the pipe stopper 43, and the water inlet pipe 41 and the water outlet pipe 42 are respectively arranged in the two clearance holes, or are both arranged in one clearance hole.

[0060] In some other alternative embodiments, the first pipe limiting member 431 and the second pipe limiting member 432 can also be fixed to the side wall of the housing 10 by means such as welding, and the assembly is achieved by passing the water inlet pipe 41 and the water outlet pipe 42 therethrough. Or the first pipe limiting member 431 and the second pipe limiting member 432 can also be provided in two parts, namely a main body and an assembly part. The assembly part is detachably or rotatably arranged on the main body, and the main body is detachably or directly fixed to the housing 10. By rotating or detaching the assembly part, the water inlet pipe 41 and the water outlet pipe 42 can be placed in the relief hole, and by assembling or rotating the assembly part, the connection between the assembly part and the main body is achieved, and the water inlet pipe 41 and the water outlet pipe 42 are fixed in the relief hole.

[0061] In some other alternative embodiments, the first pipe limiting member 431 and the second pipe limiting member 432 can also be provided in the form of pipe clamps with openings formed therein. Their structures are generally in a concave shape with the openings shrinking, and when the first pipe limiting member 431 and the second pipe limiting member 432 are installed on the housing 10, their openings face away from the housing 10, so that the water inlet pipe 41 can be clamped in the first pipe limiting member 431 through the opening, and the water outlet pipe 42 can be clamped in the second pipe limiting member 432 through the opening.

[0062] In some other alternative embodiments, the pipe limiting member 43 can also define a limiting hole alone. For example, the pipe limiting member 43 is provided in a cylindrical structure, and a part of the outer wall of the pipe limiting member 43 is fixed to the housing 10.

[0063] In some other alternative embodiments, the pipe limiting member 43 can also be provided in shapes such as a T-shape or a right angle shape. For example, when its structure is a T-shape, by fixing the horizontal side of the T-shape to the housing 10 and making the vertical hook part of the T-shape horizontally arranged, the free ends of the water inlet pipe 41 and the water outlet pipe 42 can be placed in the vertical hook part of the T-shape to achieve the limitation thereof.

[0064] In other embodiments, the presentation forms of the two pipe limiting members 43 can also be different. For example, one pipe limiting member 43 is in a "C" shape, and the other pipe limiting member 43 is in a "T" shape, etc.

[0065] In some other alternative embodiments, the structural setting of the pipe limiting member 43 can also limit the water inlet pipe 41 and the water outlet pipe 42 in the circumferential direction, so as to prevent the water inlet pipe 41 and the water outlet pipe 42 from being twisted and rotated during the installation and connection with the pipes of external devices, resulting in unnecessary stress acting on the relevant components and reducing the service life.

[0066] Specifically, the cross-sectional outer contour of at least part of the water inlet pipe 41 and the water outlet pipe 42 can be set in a polygonal shape and correspond to the cross-sectional shape of the clearance hole defined by the pipe limiter 43 (the pipe limiter 43 together with the shell 10), thereby avoiding the circular cross-sectional shape from easily rotating, causing the pipe itself to twist.

[0067] In this embodiment, the cross-sections of the partial pipe sections of the water inlet pipe 41 and the water outlet pipe 42 corresponding to the pipe limiter 43 are hexagonal (not shown in the figure), and the cross-sections (cross-sections perpendicular to the axis) of the clearance holes respectively defined by the first pipe limiter 431 and the second pipe limiter 432 and the shell 10 are also hexagonal, so that the water inlet pipe 41 and the water outlet pipe 42 are circumferentially limited in the first pipe limiter 431 and the second pipe limiter 432, respectively.

[0068] In some other optional embodiments, all pipe sections of the water inlet pipe 41 and the water outlet pipe 42 may be arranged in polygonal shapes. Specifically, the shapes may be triangles, rectangles, pentagons, or other polygonal shapes. The cross-sectional shapes and sizes of the water inlet pipe 41 and the water outlet pipe 42 may be the same or different, and are not specifically limited here.

[0069] In some other optional embodiments, when the water inlet pipe 41 and the water outlet pipe 42 share a pipe stopper 43, and the pipe stopper 43 is formed with only one clearance hole, and the water inlet pipe 41 and the water outlet pipe 42 are penetrated at the same time, the cross-sectional shape of the clearance hole depends on the position setting and the shape of the water inlet pipe 41 and the water outlet pipe 42. For example, when the cross-sections of the water inlet pipe 41 and the water outlet pipe 42 are both triangular, and the side walls where one side of the triangle is located between the two are adjacently arranged, the clearance hole can be set as a quadrilateral structure with a cross-section consisting of two triangles, etc., which are not listed here one by one.

[0070] In some embodiments, the heat pump system device 1 further includes components such as a domestic hot water heat exchanger, an electric control box, a compressor, a liquid storage tank, a gas separation module, and an indoor heat exchanger (not shown in the figure), and the domestic hot water heat exchanger, the electric control box, the compressor, the liquid storage tank, the gas separation module, and the indoor heat exchanger are all arranged below the water tank 20 and the outdoor heat exchanger 30 and the fan 50. The cubic accommodation space 11 is divided into an L-shaped chamber and a rectangular chamber by a partition plate, and the outdoor heat exchanger 30 and the fan 50 are both arranged in the rectangular chamber, and the water tank 20 is arranged at the long side of the L-shaped chamber through a supporting structure, and the domestic hot water heat exchanger, the electric control box, the compressor, the liquid storage tank, the gas separation module, and the indoor heat exchanger are all arranged at the short side of the L-shaped chamber, so as to be located below the water tank 20 and the outdoor heat exchanger 30 and the fan 50.

[0071] Specifically, the rectangular chamber where the outdoor heat exchanger 30 and the fan 50 are located is separated from the long side of the L-shaped chamber where the water tank 20 is located by a partition. Insulation cotton is also provided outside the water tank 20 to keep the domestic hot water warm. When the system operates in partial heat recovery or full heat recovery mode, the refrigerant output from the compressor enters the shell and tube heat exchanger to exchange heat with water to prepare domestic hot water, and then the domestic hot water is transported to the water tank 20. When the user needs hot water, the domestic hot water can be output to the corresponding water-using equipment through the water outlet pipe 42.

[0072] In some embodiments, a water pump (not shown in the figure) is also connected between the shell and tube heat exchanger and the water tank 20. The water pump is also arranged at the short side of the L-shaped chamber. When the heat pump system equipment 1 is running, the domestic hot water heated in the shell and tube heat exchanger is transported to the water tank 20 through the water pump.

[0073] In some embodiments, the electric control box is arranged at one end of the short side of the L-shaped chamber away from the long side of the L-shaped chamber, and is fixed to the two columns at the end. The electric control box corresponds to the position of the end of the outdoor heat exchanger 30 (i.e., located below the outdoor heat exchanger 30), and electrical components such as a main control board, relays, and reactors are arranged inside the electric control box. The electric control box is separated from the rectangular chamber where the outdoor heat exchanger 30 is located by a partition (water tray) to increase the stability of the electric control box.

[0074] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
