The tank body 101 includes a rectangular frame and a tank plate, the tank plate being located on an outer wall of the frame and having a tank opening on a side of the tank body 101. The tank body 101 further includes a tank door 103 configured to open or close the tank opening. The internal space of the tank body 101 is limited by the frame, the tank plate and the tank door 103. The tank body 101 is further provided with a water tray 102, which divides the interior space of the tank body into an upper receiving space and a lower receiving space. The water tray 102 is located on the frame. The frame is located around the perimeter of the specified water tray 102 and supports the support beam 1021 of the water tray 102. The pipe connection assembly is located above the water pan 102. The hydraulic module unit 10 is located in the tank housing 101 and is located in the upper receiving space.

The water tank 20 is located in the tank body 101 and is located in the lower receiving space. The water tank 20 has a water tank pipe assembly that extends into a pipe connection assembly and is in communication with the hydraulic pipe assembly.

[0037] In the present invention, the hydraulic module unit 10 and the water tank 20 are mounted in the integrated hot water supply tank device 100 by the tank body 101. In addition, the water tray 102 in the tank body 101 allows the interaction between the hydraulic module block 10 and the water tank 20 to be reduced, and to receive condensation and water vapor generated when the pressure in the hydraulic module block 10 is released. The water tray 102 is provided with a water guide ramp, a water storage trough, and a drainage overhang that protrudes from the tank body 101. A pipe connection assembly located above the water tray 102 may facilitate communication between the hydraulic module unit 10 and the water tank 20.

[0038] It should be noted that the hydraulic module unit 10 is used as a heat source of the water tank 20 so that the hydraulic module unit can not only heat the domestic water in the water tank 20, but also heat the indoor floors and cool the indoor fan coil unit. The structure and functions of the hot water supply tank device 100 are described in detail below as an example that the hydraulic module unit 10 is configured to heat domestic water in the water tank 20.

[0039] As shown in FIG. 4, according to an embodiment of the present invention, the hydraulic module unit 10 includes a heat exchanger 11 and an auxiliary electric heater 12, which communicate with each other. Heat exchanger 11 communicates with heat pump system 200. The circulating water in the heat exchanger 11 absorbs heat from the heat pump system 200, thereby raising its temperature, and then passes through the auxiliary electric heater 12 for reheating. The reheated circulating water passes through the water outlet pipe 121 of the auxiliary electric heater 12 and the heat input pipe 201 of the water tank 20, and then flows into the heat exchange pipe of the water tank 20. The reheated circulating water heats the domestic water in the water tank 20 through the heat exchange pipe, and then flows back to the heat exchanger 11 for reheating through the heat supply return pipe 202 of the water tank 20 and the water return pipe of the heat exchanger 11. This circulation ensures heating of domestic water in the water tank 20.

[0040] Specifically, the hydraulic module unit 10 is secured by the rectangular frame of the tank body 101. The cube frame is formed by assembling a rectangular frame and a support beam 1021 with metal plates and screws to support various members of the hydraulic module block 10. The elements of the hydraulic module block 10 are secured using a locking plate. In addition, the members of the hydraulic module block 10 are connected to each other through pipe joints, pipe nuts and copper pipes, forming an integral hydraulic module block 10.

[0041] In addition, in order to ensure sealed communication between the hydraulic module unit 10 and the water tank 20, the pipe connection assembly of the present invention includes a water outlet pipe connection 15 and a water return pipe connection 16, which are both welded to the tank top cover 23 20 for water. The water outlet pipe 121 of the electric auxiliary heater 12 is connected to the heat input pipe 201 of the tank 20 through the water outlet pipe connection 15. The water return pipe of the heat exchanger 11 is connected to the heat supply return pipe 202 of the water tank 20 through the water return pipe connection 16. Thus, sealed connections and rational arrangement are ensured between the water outlet pipe 121 and the heat supply inlet pipe 201, and between the heat supply return pipe 202 and the water return pipe.

[0042] It should be noted that in the hydraulic module unit 10, the water circulating to heat the water tank 20 needs to be periodically replenished and drained. To ensure replenishment and renewal of circulating water, the hydraulic module unit according to embodiments of the present invention further includes a three-way valve located on the heat supply inlet pipe, and an expansion tank 14 located on the water return pipe of the heat exchanger 11. A drain pipe 182 is located at the three-way valve . The water supply pipe 181 is located on the expansion tank 14. The replenishment water can flow through the water return pipe of the heat exchanger 11 through the water supply pipe 181 to become circulating water, and then flow into the heat exchange pipe of the water tank 20 through the heat supply inlet pipe. The circulating water in the heat exchange pipe can be discharged through the heat supply return pipe and the drain pipe 182. The three-way valve allows the heat supply inlet pipe to be switched between the water outlet pipe and the drain pipe 182. In addition, the use of the three-way valve can reduce the number of connections and piping, which simplifies the layout of all elements of the block 10 of the hydraulic module.

[0043] In addition, the hydraulic module unit 10 and the water tank 20 are located in the tank body 101, but the heat exchanger 11 of the hydraulic module unit 10 must be in communication with the heat pump system 200 and the drain pipe 182, and the water supply pipe 181 for circulating water must communicate with the water source outside the tank housing 101. To solve the problem of piping communication, in one embodiment of the present invention, a water supply pipe connection 1211 communicating with a water supply pipe 181, a drain pipe connection 1221 communicating with a drain pipe 182, a refrigerant inlet pipe connection 1011, and a refrigerant return pipe connection 1012 through which the The connection between the heat pump and the heat exchanger 11 is located in the upper part of the tank housing 101, which allows for a rational layout of each of the pipelines and reduces the amount of interference for the laying of pipelines.

[0044] In addition, since the domestic water in the water tank 20 needs to flow out from the tank body 101, the hot water supply tank device 100 further includes a water inlet pipe 171 extending into the water in the water tank 20, and a hot water pipe 172 water continuing from the water in the water tank 20. The pipe connection assembly further includes a first water inlet pipe connection 203 in communication with the water inlet pipe 171 and a first hot water pipe connection 204 in communication with the hot water pipe 172 . A second water inlet pipe connection 131 corresponding to the first water inlet pipe connection 203 and a second hot water pipe connection 132 corresponding to the first hot water pipe connection 204 are located at the top of the tank body 101. The connections of the water inlet pipe 171 and the hot water pipe 172 are designed to allow rational placement of the water inlet pipe 171 and the hot water pipe 172, and to reduce the number of intersections with other pipelines and interference with the water inlet pipe 171 and the pipe 172 hot water.

[0045] In addition, the connections of the water inlet pipe 171 and the hot water pipe 172 can seal the water inlet pipe 171 and the hot water pipe 172 with the water pan 102 and the tank body 101. As shown in FIG. 6, the water inlet pipe 171 extends to the bottom of the domestic water in the water tank 20, and the hot water pipe 172 extends to the top of the domestic water in the water tank 20. The domestic water in the water tank 20 flows out through the hot water pipe 172 under the action of the water pressure and the air pressure in the water tank 20, which can improve the sealing of the inlet water pipe 171 and the hot water pipe 172 with the water tray 102 and the water tank 20 , and facilitates the flow of domestic water from the water tank 20 through the hot water pipe 172.
