DETAILED DESCRIPTION

[0063] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application and not to limit the present application.

[0064] The water power module is used to exchange heat between the refrigerant in the refrigerant flow channel and the water in the water flow channel, so as to heat or cool the water, and output water at a set temperature to a water storage device such as a water tank, or to a heat dissipation device such as a floor heating pipe or a heating panel.

[0065] The inventor finds that the arrangement positions of the heat exchange device, the small water tank heater, the water pump, the expansion tank, the temperature controller and the electric control box and other components in the box are not properly designed, which is easy to cause water to be left in the internal space of these devices, and the left water is easy to cause corrosion to the internal structure of the components. For example, when the water power module is inspected, the water in the internal space of the water power module is discharged, if there is still water left, when the water power module is put into use in the user's home, a long time interval will occur, and the left water is easy to cause corrosion to the internal components. Therefore, it is necessary to set the arrangement positions of the components in the internal space of the water power module, so that the water in the internal space of the components of the water power module can be more fully discharged. Based on this, the embodiments of the present application provide a water power module and a heat pump system.

[0066] The water power module provided by the embodiments of the present application can be used in an air energy water heater, and can also be used in a home heating device such as a floor heating pipe or a heating panel, which is not specifically limited here. As shown in Figures 1 to 3 The water power module 10 provided by an embodiment of the present application is shown in FIG. 1, which is a structural schematic diagram of the water power module 10.

[0067] The water power module 10 provided by the embodiments of the present application includes a plurality of functional devices, for example, the functional devices include an expansion tank 200, a heat exchange device 300, a water tank 400 and a water pump 500, etc.

[0068] The heat exchange device 300 has a water flow channel and a refrigerant flow channel inside, and the water flow channel and the refrigerant flow channel respectively flow fluids with different temperatures, and the heat of the fluids in the water flow channel and the refrigerant flow channel is exchanged to regulate the temperature of the fluid in the water flow channel. The heat exchange device 300 includes a temperature sensing assembly extending into the internal space of the water flow channel, which is used to obtain the temperature of the fluid in the water flow channel, so as to regulate the temperature of the fluid in the refrigerant flow channel according to the temperature of the fluid in the water flow channel, and further regulate the temperature of the fluid output from the water flow channel to be within a preset temperature range.

[0069] The water channel has a first water inlet 310a at one end and a first water outlet 320a at the other end. The first water inlet 310a is used to connect with an external water source. The water flow from the external water source enters the water channel from the first water inlet 310a and is output from the first water outlet 320a. The flow direction of the fluid in the water channel is opposite to that of the fluid in the refrigerant channel, so as to improve the heat exchange efficiency between the fluid in the water channel and the fluid in the refrigerant channel. The temperature probe assembly is used to detect the temperature of the water flow at and near the first water inlet 310a and the first water outlet 320a, so as to obtain the temperature state of the water flow in the water channel. The heat exchange device 300 includes a plate heat exchanger 300, a tube heat exchanger 300, etc.

[0070] The water tank 400 has a water storage cavity. The water tank 400 also has a second water inlet 410a and a second water outlet 420a that communicate with the water storage cavity. The water flow enters the water tank 400 from the second water inlet 410a and flows out of the water storage cavity from the second water outlet 420a. Part of the water entering the water tank 400 is temporarily stored in the water storage cavity. The water tank 400 has a heater that is used to heat the water stored in the water storage cavity, so as to regulate the temperature of the water flow output from the second water outlet 420a of the water tank 400.

[0071] The water pump 500 has a water suction end 510 and a water delivery end 520. The water suction end 510 of the water pump 500 is used to communicate with at least one of the water tank 400 or the heat exchange device 300. The water delivery end 520 of the water pump 500 is used to communicate with the outside. The water flow enters the water pump 500 from the water suction end 510 and is output to the outside structure from the water delivery end 520. The water pump 500 is used to provide water delivery power, so that the water in the water power module 10 can flow in the internal space of the water tank 400 and the heat exchange device 300.

[0072] The expansion tank 200 has an expansion port 210 that is used to communicate with at least one of the water tank 400 or the heat exchange device 300. The expansion tank 200 is used to balance the pressure change of the water in the system due to the temperature change. When the water temperature rises, the volume expands, which causes the pressure in the water pipe to increase. The provision of the expansion tank 200 can cause the expanded water in the system to press into the expansion tank 200, thereby achieving the pressure balance of the water system within a certain range.

[0073] The first water outlet 320a communicates with the second water inlet 410a, and the second water outlet 420a communicates with the water suction end 510 of the water pump 500. When the water pump 500 operates, it drives the water flow to enter the water channel from the first water inlet 310a, to flow to the second water inlet 410a from the first water outlet 320a and to flow into the water storage cavity. The water in the water storage cavity is pumped from the second water outlet 420a to the water suction end 510 of the water pump 500. The water in the water pump 500 is then supplied to the outside structure from the water delivery end 520, for example, the water delivery end 520 communicates with the heating pipe of the floor heating, etc.

[0074] like Figure 2 As shown, in the direction of gravity G, the water pump 500 is located below the water tank 400, the expansion tank 200 is located above the heat exchange device 300, the first inlet 310a is lower than the first outlet 320a, the first outlet 320a is connected to the second inlet 410a, and the first outlet 320a is lower than the second inlet 410a, or the first outlet 320a is flush with the second inlet 410a, the second inlet 410a is lower than the second outlet 420a, and the second outlet 420a is connected to the water intake end 510 of the water pump 500. Thus, when it is necessary to drain the water inside the hydraulic module 10, under the action of gravity, the water in the water storage chamber of the water tank 400 can flow out sequentially through the second inlet 410a, the first outlet 320a, the water delivery channel, and the first inlet 310a. Furthermore, the second outlet 420a, which is connected to the water pump 500, is also located above the water pump 500 in the direction of gravity G. The water flow inside the structural component connecting the second outlet 420a and the water intake end 510 of the water pump 500 is also more easily and fully discharged under the action of gravity. In addition, the water tank 400 adopts a bottom-in, top-out water supply method. When heating the water in the storage chamber, water is stored in the lower area of ​​the storage chamber, which reduces the risk of boiling dry and improves safety during use.

[0075] The expansion port 210 of the expansion tank 200 is connected to the first inlet 310a, thus enabling the expansion tank 200 to also connect to the water supply channel of the heat exchange device 300 and the water storage chamber of the water tank 400, thereby balancing the pressure within the water supply channel of the heat exchange device 300 and the water storage chamber of the water tank 400. In the direction of gravity G, the first inlet 310a is located in a relatively lower region of the hydraulic module 10. The area below the hydraulic module 10 has a large space, facilitating the installation of structural components for detecting and adjusting the pressure within the water supply channel of the heat exchange device 300. This results in a compact overall layout of the hydraulic module 10, facilitating maintenance and installation.

[0076] In the horizontal direction, the first inlet 310a and the first outlet 320a are both opened towards the side where the water tank 400 is located, and the second inlet 410a and the second outlet 420a are both opened towards the side where the heat exchange device 300 is located. This facilitates the connection between the first outlet 320a and the second inlet 410a, and also reduces the number of reversals of the structural components connecting the first outlet 320a and the second inlet 410a. In addition, this arrangement also allows the structural components connected to the first inlet 310a, the first outlet 320a, the second inlet 410a and the second outlet 420a to be positioned more between the water tank 400 and the heat exchange device 300, making the overall layout of the hydraulic module 10 compact and facilitating the reduction of the thickness of the hydraulic module 10.

[0077] The heat exchange device 300 comprises a heat exchange box, which has a water flow channel and a refrigerant flow channel inside. The heat exchange device 300 further comprises a first water inlet interface 310 and a first water outlet interface 320. The first water inlet interface 310 has a first water inlet 310a, and the first water outlet interface 320 has a first water outlet 320a. The first water inlet interface 310 and the first water outlet interface 320 are protruded on the outer surface of the heat exchange box, so as to connect structural members to the first water inlet interface 310 and the first water outlet interface 320, and realize the communication of the first water inlet 310a and the first water outlet 320a with corresponding structural members.

[0078] In the gravity direction G, the first water inlet 310a and the first water outlet 320a are arranged side by side along a first straight line A, so that the first water inlet 310a and the first water outlet 320a are arranged on the same straight line, facilitating the arrangement of the positions of the structural members connected to the first water inlet 310a and the first water outlet 320a, and preventing the structural members from interfering with each other and the structural members communicating with the refrigerant flow channel, so that the structural members connected to the heat exchange device 300 are arranged in order, facilitating maintenance and installation.

[0079] The water tank 400 comprises a water tank main body having a water storage cavity. The water tank 400 further comprises a second water inlet interface 410 communicating with a second water inlet 410a and a second water outlet interface 420 communicating with a second water outlet 420a. The second water inlet interface 410 and the second water outlet interface 420 are protruded on the outer surface of the water tank 400, so as to arrange structural members on the second water inlet interface 410 and the second water outlet interface 420, and realize the communication of the second water inlet 410a and the second water outlet 420a with corresponding structural members.

[0080] In the gravity direction G, the second water inlet 410a and the second water outlet 420a are arranged side by side along a second straight line B, so that the second water inlet 410a and the second water outlet 420a are arranged on the same straight line, further improving the compactness of the water tank 400 and the structural members of the connecting head on the water tank 400, and helping to reduce the size of the hydraulic module 10.

[0081] The hydraulic module 10 further comprises an integrated pipeline subsystem, which comprises a plurality of connecting pipelines. Two functional devices of the hydraulic module 10 are connected through at least one connecting pipeline. For example, the first water outlet 320a of the heat exchange device 300 is communicated with the second water inlet 410a of the water tank 400 through one connecting pipeline or two connecting pipelines; the second water outlet 420a of the water tank 400 is communicated with the water suction end 510 of the water pump 500 through one connecting pipeline or two connecting pipelines. The number of connecting pipelines for communicating two functional devices is not limited in the present application, and can be selected according to actual needs.

[0082] Optionally, one of the connecting pipes of the integrated pipe subsystem is a transition pipe 610, which is connected to the first water outlet 320a and the second water inlet 410a, specifically, one end of the transition pipe 610 is connected to the first water outlet interface 320 to communicate with the water conveying channel, and the other end of the transition pipe 610 is connected to the second water inlet interface 410 to communicate with the water storage cavity.

[0083] The transition pipe 610 is a transition straight pipe, the axial direction of which is perpendicular to the first straight line A and the second straight line B. The first water outlet 320a and the second water inlet 410a are connected through the transition straight pipe, which facilitates the smooth flow of water between the first water outlet 320a and the second water inlet 410a, and makes the pipe connecting the first water outlet 320a and the second water inlet 410a occupy less space.

[0084] Further, the central axis of the transition straight pipe is located in the plane defined by the first straight line A and the second straight line B, i.e., the central axes of the first water outlet 320a, the first water inlet 310a, the second water outlet 420a, and the second water inlet 410a are coplanar, so that the water tank 400 and the heat exchange device 300 can be coplanar, which facilitates the compact structure of the water power module 10 and the smooth flow of water in the water tank 400, the heat exchange device 300, and the connecting pipe.

[0085] At least one of the connecting pipes of the integrated pipe subsystem forms a water tank flow guide pipe 620, one end of which is connected to the second water outlet interface 420, and the other end of which is connected to the water pumping end 510 of the water pump 500, so as to connect the second water outlet 420a and the water pumping end 510 of the water pump 500 through the water tank flow guide pipe 620. In the gravity direction G, the water pump 500 is located below the water tank 400, so that the second water inlet 410a and the second water outlet 420a are both higher than the water pump 500. Therefore, the length of the water tank flow guide pipe 620 connecting the second water outlet 420a and the water pumping end 510 of the water pump 500 also needs to be designed to be relatively long, and the water tank flow guide pipe 620 can be formed by connecting two or three connecting pipes, so as to facilitate assembly.

[0086] When the water tank flow guide pipe 620 connects the second water outlet 420a and the water pumping end 510 of the water pump 500, the water tank flow guide pipe 620 can be optionally designed to extend from the second water outlet 420a, pass the outside of the transition pipe 610, and then extend to be connected to the water pumping end 510 of the water pump 500, so that the water tank flow guide pipe 620 can also be concentrated between the water tank 400 and the heat exchange device 300, and the installation space can be fully utilized. The water tank flow guide pipe 620 designed in this way has a multi-segment bending structure, and can optionally include a first straight pipe 621, a second straight pipe 622, and a third straight pipe 623 connected in sequence, the first straight pipe 621 and the third straight pipe 623 are arranged at an angle with the second straight pipe 622,

[0087] Specifically, as shown in Figure 3 The axial direction of the first straight pipe 621 is perpendicular to the second straight line B, and the first straight pipe 621 is connected to the second water outlet 420a, for example, the second water outlet interface 420 is protruded on the outer surface of the water tank body, the axial direction of the second water outlet interface 420 is parallel to the axial direction of the transition straight pipe, the first straight pipe 621 is connected to the second water outlet interface 420, and the axial direction of the first straight pipe 621 is perpendicular to the axial direction of the second water outlet interface 420. The second straight pipe 622 is connected to the first straight pipe 621, extends from the first straight pipe 621 in a direction parallel to the second straight line B to the outside of the transition pipe 610 and extends to be connected to the third straight pipe 623, for example, the axial directions of the first straight pipe 621, the second straight pipe 622 and the second water outlet interface 420 form an angle with each other. The third straight pipe 623 extends from the second straight pipe 622 in a direction forming an angle with the second straight line B to be connected to the water suction end 510 of the water pump 500. In this way, the water tank flow guide pipe 620 has a two-segment bending structure, and the bending angle of the bending part of the water tank flow guide pipe 620 can be large, which facilitates the flow of water and smooth drainage.

For example, the various plate bodies of the heat preservation support can be connected with adjacent plate bodies to fix the position of the adjacent two plate bodies; or the various plate bodies of the heat preservation support are in abutment with the inner wall surface of the box body 100 to fix the position of the adjacent two plate bodies; or the various plate bodies of the heat preservation support are installed in a combined manner of adjacent plate body connection and plate body abutment with the inner wall surface of the box body 100 to fix the position of the adjacent two plate bodies.

[0138] The water power module 10 further comprises an electric control box 800, which has a conductive element inside. In the gravity direction G, the distance from the electric control box 800 to the top wall 110 is less than the distance from the electric control box 800 to the bottom wall 120. The electric control box 800 is arranged in the upper region of the accommodation cavity 100a of the box body 100, so as to prevent the conductive element from being short-circuited in the humid region at the bottom of the accommodation cavity 100a. The electric control box 800 is arranged outside the heat preservation support and is in abutment with the heat preservation support, for example, the electric control box 800 is in abutment with the second plate body 32, or the electric control box 800 is in abutment with the second plate body 32 and the sixth plate body 36, thereby improving the installation stability of the various plate bodies of the heat preservation support.

[0139] The front side wall can be opened or closed. Optionally, the electric control box 800 is arranged on the front side wall, and the electric control box 800 can move with the front side wall. After the front side wall is opened, the second plate body 32, the fifth plate body 35 or other plate bodies of the heat preservation support can be disassembled, so that the devices in the box body 100 can be maintained, which is convenient to operate.

[0140] The heat preservation support is a polypropylene foam board, which has good structural strength and can provide stable support for the functional device, and has good heat insulation effect. Alternatively, in some other embodiments, the heat preservation support includes a hard support shell and a heat preservation material layer filled in the internal space of the hard support shell.

[0141] The hydraulic module 10 further includes a water receiving tray 140 arranged in the accommodating cavity 100a and mounted on the bottom wall 120. As shown, the middle region of the water receiving tray 140 has a plurality of docking openings 140a, each of which corresponds to one of the pipe mounting openings of the bottom wall 120. Figure 8

[0142] The integrated pipe subsystem includes a plurality of pipe interfaces 640 for docking with external systems, for example, the pipe interfaces 640 of the integrated pipe subsystem include, but are not limited to, interfaces connected to pipes such as the refrigerant input pipe 704, the refrigerant output pipe 705, the expansion flow guide pipe 630, the water pump 500 water delivery end 520, etc.

[0143] Each pipe interface 640 penetrates one of the docking openings 140a, and each pipe interface 640 is fixed to the water receiving tray 140. The liquid condensed on the outer surface of the device of the integrated pipe subsystem is left at the pipe interface 640 under the action of gravity and flows along the surface of the pipe interface 640 to the water receiving tray 140. Among them, the plurality of docking openings 140a of the water receiving tray 140 are arranged in the middle region of the water receiving tray 140, and the plurality of pipe interfaces 640 of the integrated pipe subsystem are installed in correspondence with the middle region of the water receiving tray 140, preventing the pipe interfaces 640 from contacting the inner wall of the cabinet 100, causing the liquid condensed on the surface of the device of the integrated pipe subsystem to flow along the inner wall of the cabinet 100 to the bottom wall 120 and not being able to be discharged on the bottom wall 120, so that the water receiving tray 140 can more comprehensively collect the water droplets falling from the surface of the functional device and the surface of the device of the integrated pipe subsystem, and the water vapor can be more discharged through the water receiving tray 140, reducing the humidity in the internal space of the cabinet 100.

[0144] The water receiving tray 140 includes a water receiving main body portion 142 and a plurality of protruding portions 141, and the protruding portions 141 are protruding from the surface of the water receiving main body portion 142 away from the bottom wall 120. Each protruding portion 141 has one docking opening 140a, and when the pipe interface 640 is installed in correspondence with the docking opening 140a, the water flow can flow in sequence through the surface of the pipe interface 640, the surface of the protruding portion 141, and the water receiving main body portion 142, preventing the water flow from being left at the docking opening 140a.

[0145] ​The pipe interface 640 is fixed to at least one of the protruding portion 141 and the water receiving main body portion 142. For example, the pipe interface 640 is fixed to the protruding portion 141, and the portion of the pipe interface 640 closer to the docking opening 140a is fixed, which improves the stability of the pipe interface 640 fixed to the water receiving tray 140 and improves the sealing performance of the connection between the pipe interface 640 and the water receiving tray 140.

[0146] The water receiving tray 140 further comprises an interface sealing gasket arranged between the pipe interface 640 and the protruding portion 141, which seals the gap between the pipe interface 640 and the protruding portion 141 and prevents water vapor from entering the docking opening 140a from the gap between the pipe interface 640 and the protruding portion 141.

[0147] The water receiving tray 140 has a water collecting groove 140c and a drain port 142a, which is arranged on the bottom wall 120 of the water collecting groove and through which the water collected in the water collecting groove 140c is drained to the outside. In the gravity direction G, the drain port 142a is lower than the docking opening 140a, which further prevents the water collected in the water collecting groove 140c from overflowing into the docking opening 140a. For example, the drain port 142a is arranged on the surface of the water receiving main body portion 142.

[0148] The drain pipe 706 in communication with the pressure relief valve 703 passes through the drain port 142a to communicate with the outside atmosphere, and the opening through which the drain pipe 706 passes is the same opening as the drain port 142a, which simplifies the structure of the water receiving tray 140, reduces the number of openings on the water receiving tray 140, and further reduces the occurrence of water falling from the openings of the water receiving tray 140 to the bottom wall 120 of the cabinet 100.

[0149] Optionally, the outer diameter of the drain pipe 706 is smaller than the inner diameter of the drain port 142a, and the water in the water collecting groove 140c can flow out between the outer surface of the drain pipe 706 and the wall surface of the water receiving tray 140 defining the drain port 142a. In some other embodiments, the outer surface of the portion of the drain pipe 706 passing through the drain port 142a is provided with an opening or a groove, and the water in the water collecting groove 140c can be drained from the opening or the groove of the outer surface of the drain pipe 706.

[0150] Optionally, the pipe interface 640 has a flow guide flange 641, the pipe interface 640 passes through one of the docking openings 140a, and the flow guide flange 641 covers the corresponding docking opening 140a and is connected to the surface of the water receiving tray 140. The docking opening 140a is closed by the flow guide flange 641, and the flow guide flange 641 can guide the water flow into the water collecting groove 140c of the water receiving tray 140.

[0151] The flow guide flange 641 extends away from the center axis of the docking opening 140a, and is fixed to the water pan 140. The flow guide flange 641 increases the contact area between the pipeline interface 640 and the water pan 140, thereby improving the installation stability of the pipeline interface 640.

[0152] Optionally, the flow guide flange 641 covers the protruding portion 141 and is fixed to the protruding portion 141; or the flow guide flange 641 covers the protruding portion 141 and extends to the water pan body portion 142, so that the distance between the outer edge of the flow guide flange 641 and the docking opening 140a is greater, further reducing the probability of water flowing into the docking opening 140a. For example, the flow guide flange 641 is fixed to the protruding portion 141 of the water pan 140, and the flow guide flange 641 is fixed to the water pan 140 by screws.

[0153] As shown, the pipeline interface 640 includes a first interface 6401 and a second interface 6402. The first interface 6401 is arranged in the accommodation cavity 100a, and the second interface 6402 is arranged on the side of the bottom wall 120 away from the first interface 6401. The second interface 6402 passes through the pipeline installation opening, the docking opening 140a, and is inserted into the flow channel of the first interface 6401 in sequence. The first interface 6401 abuts and is fixed to the water pan 140, and the second interface 6402 abuts and is fixed to the bottom wall 120. The first interface 6401 has a flow guide flange 641, and the second interface 6402 has a mounting flange 642. The flow guide flange 641 and the mounting flange 642 can increase the contact area, thereby improving the installation stability of the pipeline interface 640 installed at the docking opening 140a.

[0154] The water pan 140 includes a folded portion 143 connected to the outer periphery of the water pan body portion 142. The folded portion 143 is in contact with the inner wall surface of the peripheral side wall 130. The folded portion 143, the water pan body portion 142, and the protruding portion 141 define a water collecting groove 140c. The water collecting groove 140c has a depth in the gravity direction G, so that the water collecting groove 140c can store a certain volume of accumulated water, preventing the accumulated water in the water collecting groove 140c from overflowing out of the water collecting groove 140c.

[0155] The edge region of the water pan 140 is in contact with the inner wall surface of the peripheral side wall 130. Specifically, the folded portion 143 of the water pan 140 is in contact with the inner wall surface of the peripheral side wall 130, so that the water pan 140 corresponds to more functional devices in the lower region of the cabinet 100, thereby more comprehensively collecting water droplets falling from the functional devices.

[0156] The turnover portion 143, the water receiving main body portion 142 and the protruding portion 141 are integrally provided, for example, integrally injection molded or integrally suction molded, the process is simple, the overall thickness of the water receiving tray 140 is thin, the water receiving tray 140 occupies small space of the box body 100, and the water power module 10 is facilitated to be miniaturized.

[0157] The embodiment of the present application also provides a heat pump system, which comprises the water power module 10, water flow in the internal space of the functional device of the water power module 10 can be more fully discharged, the humidity in the box body 100 of the water power module 10 can be lower, the devices of the water power module 10 of the embodiment of the present application can be in a relatively dry good environment, so that the water power module 10 has good use stability, and further the heat pump system provided with the water power module 10 also has good use stability.
