[0039] First embodiment:

[0040] Figure 1 and Figure 2 The heat pump system device 1 in the first embodiment of the utility model is shown. The heat pump system device 1 includes a frame 10 and a water circulation module 20. The frame 10 defines a receiving chamber 13. The water circulation module 20 is arranged in the receiving chamber 13 to recover waste heat or recover all heat while circulating the refrigerant to carry out water circulation to generate domestic hot water at a certain temperature.

[0041] The frame 10 includes a frame body 11, a partition 12 and at least one support member 14, wherein the at least one support member 14 is disposed below the frame body 11 and is used to support the entire heat pump system device, and the accommodating cavity 13 is formed in the frame body 11. The partition 12 is disposed in the frame body 11 and divides the accommodating cavity 13 into at least two chambers, so as to facilitate the integrated block arrangement of the water circulation module 20, reasonably utilize the space in the accommodating cavity 13, and reduce the volume of the heat pump system device 1.

[0042] In this embodiment, there are two support members 14, which are symmetrically disposed below the frame 11. The partition 12 is horizontally disposed in the frame 11, dividing the accommodating cavity 13 into a first cavity 131 located at the top and a second cavity 122 located at the bottom.

[0043] The water circulation module 20 includes a water tank 21, a heat exchanger 22 and a compressor 23, wherein the water tank 21 is disposed in one of the first chamber 131 and the second chamber 122, and the heat exchanger 22 and the compressor 23 are disposed in the other of the two chambers. The water tank 21 and the heat exchanger 22 are connected to form a water circulation loop through a pipeline, and the heat exchanger 22 can be a shell-and-tube heat exchanger. The heat exchanger 22 and the compressor 23 are connected to form a water heating loop through a pipeline. The water circulation loop and the water heating loop perform heat exchange between the refrigerant and the water through the heat exchanger 22 to heat the domestic water in the water tank 21.

[0044] Specifically, the water tank 21 is arranged in a longitudinal direction and horizontally arranged in the second chamber 122, which can lower the center of gravity of the heat pump system device 1 and improve the stability of the device. The heat exchanger 22 and the compressor 23 are both arranged in the first chamber 131. In some embodiments, the volume of the water tank 21 is adapted to the volume of the second chamber 122 to maximize the capacity of the water tank 21 and reduce the space occupied by the second chamber 122.

[0045] In some embodiments, the capacity of the water tank 21 is 78L.

[0046] Read also Figure 3 and Figure 4The water tank 21 includes a box body 211, and the box body 211 is formed with a first connection port 2111 and a second connection port 2112 for connecting the inner space of the box body 211 with the outside. The heat exchanger 22 is formed with a cold water inlet, a hot water outlet, a first refrigerant port and a second refrigerant port. The water circulation module 20 also includes a first connecting pipe 24 and a second connecting pipe 25.

[0047] One end of the first connecting pipe 24 extends to the inside of the tank 211 through the first connecting port 2111, and the other end is connected to the cold water inlet. One end of the second connecting pipe 25 extends to the inside of the tank 211 through the second connecting port 2112, and the other end is connected to the hot water outlet. The domestic water in the water tank 21 flows out from the first connecting port 2111, enters the heat exchanger 22 through the first connecting pipe 24 and the cold water inlet, and becomes hot water after heat exchange and returns to the water tank 21 through the hot water outlet, the second connecting pipe 25 and the second connecting port 2112.

[0048] In some embodiments, the water circulation module 20 further includes a water pump, which is disposed between the first connection port 2111 and the cold water inlet and is used to provide power for outputting water in the water tank.

[0049] In some embodiments, the box 211 is also formed with a water inlet 2113 and a water outlet 2114 that also connect the internal space of the box 211 with the outside. The water circulation module 20 also includes a water inlet pipe 26 and a water outlet pipe 27, wherein one end of the water inlet pipe 26 extends to the inside of the box 211 through the water inlet 2113, and the other end extends to the outside of the rack 10 through the wall of the frame 11, and is used to add domestic water to the water tank 21 for output after heating. One end of the water outlet pipe 27 extends to the inside of the box 211 through the water outlet 2114, and the other end also extends to the outside of the rack 10 through the wall of the frame 11, and is used to transmit the heated domestic water to the outside of the device and flow out through the terminal device for use.

[0050] It should be understood that since the density of hot water is less than that of cold water, the hot water is located above the cold water in the same space. In order to improve the heat exchange efficiency and avoid the hot water from repeatedly passing through the first connecting pipe 24 to enter the heat exchanger 22 for heating, and avoid outputting hot water with substandard temperature to the terminal equipment or directly being used by the user, the first connecting pipe 24, the second connecting pipe 25, the water inlet pipe 26 and the water outlet pipe 27 extend to the space inside the box 211 through the first connecting port 2111, the second connecting port 2112, the water inlet 2113 and the water outlet 2114 respectively, and the distribution of the pipe ports in the box 211 makes the temperatures of the domestic water flowing in different pipes different.

[0051] Specifically, Figure 4As shown, the height position of one end of the second connecting pipe 25 in the box body 211 is higher than the height position of one end of the first connecting pipe 24 in the box body 211, so as to ensure that the hot water output from the second connecting pipe 25 is output to a higher position in the space of the box body 211, and the domestic water flowing into the first connecting pipe 24 is cold water that has not been heated, thereby reducing the heat exchange between cold water and hot water.

[0052] Similarly, the height position of one end of the water outlet pipe 27 in the box body 211 is higher than the height position of one end of the water inlet pipe 26 in the box body 211, so as to ensure that the temperature of the hot water flowing out of the water outlet pipe 27 is higher, and the cold water to be heated flowing into the box body 211 from the water inlet pipe exchanges heat with the hot water as little as possible.

[0053] It should be understood that the “height position” refers to the height of each component when the water tank 21 is disposed in the frame 10 with the bottom plate (or ground, horizontal plane) of the frame 10 as a reference surface.

[0054] In some embodiments, the height position of one end of the water outlet pipe 27 in the box body 211 is higher than the height position of the second connecting pipe 25 in the box body 211, so as to ensure that the high-temperature hot water at the highest height (highest temperature) in the box body 211 is output from the box body 211 to the terminal device for use.

[0055] In some embodiments, the height position of one end of the first connecting pipe 24 in the box 211 is higher than the height position of one end of the water inlet pipe 26 in the box 211, so as to ensure that the domestic water just input into the box 211 by the water inlet pipe 26 (the water with the lowest temperature in the box 211 at the same time) is located below the water in the box 211.

[0056] Read also Figure 6 In order to further reduce the heat exchange between cold water and hot water and improve the heat exchange efficiency as much as possible, in some embodiments, one end of the water inlet pipe 26 and one end of the first connecting pipe 24 are located at one end inside the box 211, and one end of the water outlet pipe 27 is located at the other end inside the box 211 to ensure that in the axial distribution of the box 211, the water outlet pipe 27 outputting hot water is as far away as possible from the water inlet pipe 26 inputting cold water and the first connecting pipe 24 outputting cold water.

[0057] In some embodiments, the horizontal position of one end of the second connecting pipe 25 in the box body 211 is between the horizontal position of one end of the water outlet pipe 27 in the box body 211 and the horizontal position of one end of the first connecting pipe 24 (or the water inlet pipe 26) in the box body 211. Specifically, the water outlet pipe 27 of the water tank is arranged as close to the upper wall of the water tank 21 as possible, and due to the principle that hot water is heavy and cold water is light, the water inlet pipe 26 is located at the lower wall of the water tank as much as possible, so that the cold water entering the water inlet pipe 26 and the hot water discharged from the hot water pipe are isolated as much as possible, thereby ensuring the maximum hot water discharge.

[0058] It should be understood that the “horizontal position” refers to the position of each component on the same horizontal plane without considering the height factor (that is, all height positions are regarded as the same height position).

[0059] In some embodiments, the first connection port 2111, the second connection port 2112, the water inlet 2113 and the water outlet 2114 are all formed at one end of the box body 211, so as to ensure that one end of the first connection pipe 24, the second connection pipe 25, the water inlet pipe 26 and the water outlet pipe 27 are all extended from one end of the box body 211 to the other end, so as to ensure that the hot water output from the second connection pipe 25 is sprayed from the pipe into the box body 211 and approaches one end of the water outlet pipe 27 under the action of inertia. At the same time, it is also convenient for the installation and maintenance of the pipeline, and at the same time, the compactness of the pipeline layout outside the box body 211 can be reduced, the volume of the water tank 21 can be reduced, and the miniaturization of the heat pump system device 1 can be facilitated.

[0060] like Figure 5 As shown, in this embodiment, the water inlet 2113 and the water outlet 2114 are located on the same side of the vertical section where the axis of the box body 211 is located, the first connection port 2111 and the second connection port 2112 are located on the horizontal section where the axis of the box body 211 is located, and the line between the first connection port 2111 and the second connection port 2112 is perpendicular to the line between the water inlet 2113 and the water outlet 2114.

[0061] In some embodiments, at least part of the outlet pipe 27 is a nano straight heating pipe, which is used to perform secondary heating on the domestic water in the outlet pipe 27. Alternatively, a PTC heater is provided on one side of the water tank to perform auxiliary heating on the water in the water tank.

[0062] In some embodiments, the first connecting pipe 24 and / or the second connecting pipe 25 and / or the water inlet pipe 26 and / or the water outlet pipe 27 are formed with a plurality of through holes along the thickness direction of the pipe wall at one end in the box body 211 .

[0063] like Figure 1 and Figure 3 As shown, in some embodiments, the water tank 21 also includes a drain valve 212. A drain port is provided on the lower side of the box body 211. The drain valve 212 is provided on the drain port for discharging domestic water in the water tank 21 to facilitate maintenance and the like.

[0064] It should be understood that the arrangement of the two support members 14 can provide a space for the drain valve 212 to be installed, thereby preventing the protruding drain valve 212 from being squeezed or damaged during placement and transportation.

[0065] In some embodiments, the frame 10 further includes at least two stoppers 15, which are disposed on the lower wall of the frame body 11, and the drain valve 212 is disposed between the at least two stoppers 15, so as to further protect the drain valve 212 from being squeezed or damaged during transportation. In this embodiment, there are two stoppers 15, which are disposed on the front and rear sides of the drain valve 212, respectively.

[0066] like Figure 4 As shown, in some embodiments, the water tank 21 further includes a heat preservation cover 213 , which is disposed outside the box body 211 for heat preservation and reducing heat loss of domestic water in the box body 211 .

[0067] Second embodiment:

[0068] The utility model also constructs another embodiment of the heat pump system device 1, and the main difference between this embodiment and the first embodiment is that:

[0069] In this embodiment, the partition 12 is vertically arranged in the frame 11 to divide the accommodating chamber 13 into two adjacent chambers on the left and right or front and back. The water tank 21 is vertically arranged in one of the chambers, and the heat exchanger 22 and the compressor 23 are arranged in the other chamber.

[0070] In this embodiment, one end of the first connecting pipe 24 and one end of the water inlet pipe 26 are located at one side of the box body 211, and one end of the water outlet pipe 27 is located at the other side of the box body 211, so as to reduce the heat exchange between cold water and hot water as much as possible. Specifically, the water outlet pipe 27 of the water tank is arranged as close to the upper wall of the water tank 21 as possible, and due to the principle that hot water is heavy and cold water is light, the water inlet pipe 26 is located as much as possible at the lower wall of the water tank, so that the cold water entering the water inlet pipe 26 and the hot water discharged from the hot water pipe are isolated as much as possible, so as to ensure the maximum hot water discharge.

[0071] In some embodiments, one end of the second connecting pipe 25 may be located together with the water outlet pipe 27 on one side of the tank body 211, or may be located between one end of the water outlet pipe 27 and one end of the first connecting pipe 24. The end of the second connecting pipe 25 located inside the water tank is located above the end of the first connecting pipe 24 located inside the water tank, so that the hot water and cold water in the water tank 21 are separated as much as possible, so that the amount of hot water discharged is maximized.

[0072] 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.
