[0037] In order to solve the above technical problems, the specific implementation of the present application can provide a water supply system 2 for a water supply device, which is used to pass and treat a water body. The water supply system 2 for a water supply device may include a heat exchanger 3, a first waterway plate 4 and a second waterway plate 5, and the heat exchanger 3 has a medium heat exchange channel 32 and a water supply heat exchange channel 31 that are isolated from each other. The first waterway plate 4 and the second waterway plate 5 are connected to the heat exchanger 3, so as to form a circulation channel including the medium heat exchange channel 32 and a water supply channel including the water supply heat exchange channel 31.

[0038] In the structure provided in this specific embodiment, the circulation passage and the water supply passage are separated and arranged in the heat exchanger 3, the first waterway plate 4 and the second waterway plate 5, and the first waterway plate 4, the second waterway plate 5 and the heat exchanger 3 are used to splice and connect different parts of the circulation passage and the water supply passage. This can solve the problem of too complicated waterway structure in a single waterway plate, and the separately arranged first waterway plate 4 and the second waterway plate 5 are conducive to the spatial structure planning of the water supply system 2 used for the water supply device, and can reduce the volume occupied by the water supply device 1 and / or reduce the production, assembly and maintenance costs of the water supply device 1 by reasonably adjusting the installation positions of the heat exchanger 3, the first waterway plate 4 and the second waterway plate 5.

[0039] In a specific embodiment of the present application, the water supply system 2 for the water supply device may further include a heat tank 6 for accommodating a heat exchange medium. The circulation path may include a first medium channel 41 and a second medium channel 51, the first medium channel 41 is provided on the first waterway plate 4, and the second medium channel 51 is provided on the second waterway plate 5. Both ends of the medium heat exchange channel 32 can be connected to the first medium channel 41 and the second medium channel 51, respectively, and the heat tank 6 is connected to the first medium channel 41 and the second medium channel 51 to form at least part of the circulation path.

[0040] In the structure provided in this specific embodiment, by setting the first medium channel 41 and the second medium channel 51, the heat exchange medium can circulate in the same direction between the hot tank 6 and the heat exchanger 3 using the first medium channel 41 and the second medium channel 51, thereby achieving the effect of using the heat exchange medium to transfer heat from the hot tank 6 to the water supply heat exchange channel 31 in the heat exchanger 3. Since the first medium channel 41 and the second medium channel 51 are set separately, the relative positions of the two can be flexibly adjusted, so that there is enough space between the first medium channel 41 and the second medium channel 51 to accommodate the hot tank 6 and the heat exchanger 3, which is beneficial to the spatial structure planning of the water supply system 2 for the water supply device.

[0041] Alternatively, if Fig. 9 , Fig.11As shown, the circulation passage may further include a third drainage pipe 411, one end of which is connected to the first medium channel 41, and the other end is disposed in the hot tank 6 and inserted into the heat exchange medium at the bottom layer of the hot tank 6. For the same substance, the part with a higher temperature will naturally move to the upper layer, while the part with a lower temperature will remain at the bottom layer. The third drainage pipe 411 located at the lower layer of the hot tank 6 can input the heat exchange medium with a lower temperature flowing out of the heat exchanger 3 into the lower layer of the hot tank 6, so that this part of the heat exchange medium can be gradually heated in the hot tank 6 to store energy until it rises to the top layer of the hot tank 6 again.

[0042] In a specific embodiment of the present application, the water supply passage may include a first water supply passage 42, a second water supply passage 52 and a third water supply passage 43. The first water supply passage 42 and the third water supply passage 43 may be provided on the first waterway plate 4, and the second water supply passage 52 may be provided on the second waterway plate 5. The heat exchanger 3 has a water supply and heat exchange passage 31, and both ends of the water supply and heat exchange passage 31 are respectively connected to the first water supply passage 42 and the second water supply passage 52. One end of the second water supply passage 52 away from the water supply and heat exchange passage 31 can be connected to the third water supply passage 43, thereby forming at least a portion of the water supply passage.

[0043] For the water supply passage, water can be input into the water supply heat exchange passage 31 of the heat exchanger 3 through the first water supply passage 42, so as to perform a heat exchange process with the heat exchange medium in the medium heat exchange passage 32. The water that has completed the heat exchange process can enter the second water supply passage 52 from the other end of the water supply heat exchange passage 31, and then return to the first waterway plate 4 through the second water supply passage 52, so as to be output to the outside of the water supply heat exchange passage 31 through the third water supply passage 43 of the first waterway plate 4.

[0044] In the structure provided in this specific embodiment, by arranging the first water supply channel 42 of the input water body and the third water supply channel 43 of the output water body on the first waterway plate 4, and arranging the second water supply channel 52 of the transfer water body on the second waterway plate 5, the interface between the water supply passage and the outside world can be centrally arranged, which is beneficial to the spatial structure planning of the water supply system 2 used for the water supply device.

[0045] like Figure 3 As shown, a first valve body 421 may be connected to the first water supply channel 42, and the first valve body 421 can control the connection or disconnection of the first water supply channel 42, thereby controlling the input and output of water in the water supply passage.

[0046] In a specific embodiment of the present application, the first waterway plate 4 and the second waterway plate 5 can be arranged on the same side of the heat exchanger 3. Compared with arranging the first waterway plate 4 and the second waterway plate 5 on different sides of the heat exchanger 3, arranging the first waterway plate 4 and the second waterway plate 5 on the same side of the heat exchanger 3 can control the size of the water supply system 2 for the water supply device in a single direction, thereby facilitating the miniaturization of the volume of the water supply device 1.

[0047] In a specific embodiment of the present application, the water supply system 2 for the water supply device may further include a frame 9. The frame 9 has a first side surface 91 and a second side surface 92, and the first side surface 91 is connected to the second side surface 92. The heat exchanger 3 is arranged on the periphery of the frame 9 in parallel with the first side surface 91, the first waterway plate 4 is arranged on the second side surface 92, and the second waterway plate 5 is arranged on the first side surface 91 and is located between the heat exchanger 3 and the first side surface 91.

[0048] The heat exchanger 3 may be provided with a medium inlet 321, a medium outlet 322, a water supply inlet 311 and a water supply outlet 312, wherein the medium outlet 322 connects the medium heat exchange channel 32 and the first medium channel 41. The medium inlet 321 connects the medium heat exchange channel 32 and the second medium channel 51, the water supply inlet 311 connects the first water supply channel 42 and the water supply heat exchange channel 31, and the water supply outlet 312 connects the second water supply channel 52 and the water supply heat exchange channel 31. Among them, the medium inlet 321, the medium outlet 322, the water supply inlet 311 and the water supply outlet 312 are arranged on the side of the heat exchanger 3 facing the first side surface 91.

[0049] In the structure provided in this embodiment, by setting a frame 9, the first side surface 91 and the second side surface 92 of the frame 9 can be used to limit the relative positions of the heat exchanger 3, the first waterway plate 4, and the second waterway plate 5, so as to realize the layout of the water supply system 2 for the water supply device, which is beneficial to the spatial structure planning of the water supply system 2 for the water supply device, and can reduce the volume occupied by the water supply device 1 and / or reduce the production, assembly and maintenance costs of the water supply device 1 by reasonably adjusting the installation positions of the heat exchanger 3, the first waterway plate 4, and the second waterway plate 5.

[0050] Optionally, the frame 9 of the second side 92 may be provided with one of the first screw hole 94 and the first through hole 44, the first waterway plate 4 may be provided with the other of the first screw hole 94 and the first through hole 44, and the water supply system 2 for the water supply device may further include a threaded part, and the number of the first screw hole 94, the first through hole 44 and the threaded part correspond one to one, the threaded part is passed through the first through hole 44 and screwed to the first screw hole 94, thereby fixing the first waterway plate 4 relative to the second side 92 of the frame 9.

[0051] Optionally, the number of the first screw hole 94 , the first through hole 44 , and the threaded member may all be four.

[0052] Among them, in order to ensure the heat exchange efficiency of the heat exchanger 3, the water supply heat exchange channel 31 and the medium heat exchange channel 32 need to have sufficient contact surface area, which makes it difficult to reduce the size and volume of the heat exchanger 3. Therefore, based on the form of the heat exchanger 3, the first waterway plate 4 and the second waterway plate 5 are designed to be separated, thereby simplifying the structure of the water supply device 1 and reducing the occupied volume, which is very necessary for the water supply system 2 used for the water supply device.

[0053] like Figure 2 to Figure 4 as well as Fig.10 As shown, the second waterway plate 5 may be provided with one of the second screw hole 53 and the second through hole 93, the frame 9 located on the first side 91 may be provided with the other of the second screw hole 53 and the second through hole 93, the water supply system 2 for the water supply device may include at least one screw member, and the second through hole 93, the second screw hole 53, and the screw member correspond one to one. The screw member can be inserted into the second through hole 93 and screwed with the second screw hole 53, so as to fix the second waterway plate 5 to the first side 91 of the frame 9.

[0054] In a specific embodiment of the present application, the medium inlet 321 and the water supply outlet 312 can be arranged at an end of the heat exchanger 3 away from the second side 92, and the medium outlet 322 and the water supply inlet 311 are arranged at an end of the heat exchanger 3 close to the second side 92.

[0055] In the structure provided in this specific embodiment, the medium inlet 321 and the water supply outlet 312 are arranged at the same end of the heat exchanger 3, and the medium outlet 322 and the water supply inlet 311 are arranged at the same end of the heat exchanger 3, so that the heat exchange medium and the water body actually flow in opposite directions in the heat exchanger 3, so that the two can fully contact in the heat exchanger 3 for heat exchange, and can be output from different positions of the heat exchanger 3. In this way, while making the heat exchange process more sufficient, through the arrangement of the medium inlet 321, the water supply outlet 312, the medium outlet 322 and the water supply inlet 311, the structural layout of the water supply system 2 for the water supply device is more reasonable, and can adapt to the split design of the first waterway plate 4 and the second waterway plate 5.

[0056] In a specific embodiment of the present application, the first side surface 91 may be vertically disposed, and the second side surface 92 may be located above the first side surface 91 .

[0057] In the structure provided in this specific embodiment, the heat exchanger 3 is also vertically arranged as the first side 91, and the first waterway plate 4 is located above the second waterway plate 5, so that the medium inlet 321 and the water supply outlet 312 are located at the lower end of the heat exchanger 3, and the medium outlet 322 and the water supply inlet 311 are located at the upper end of the heat exchanger 3, so that gravity is used to help the water body flow to the second waterway plate 5 through the water supply heat exchange channel 31, and the heat exchange medium can be input from the bottom of the heat exchanger 3 to fill the medium heat exchange channel 32, which can ensure the working efficiency of the heat exchanger 3 and make the heat exchange between the water body and the heat exchange medium more sufficient. At the same time, the structural layout of the water supply system 2 for the water supply device is more reasonable, which can adapt to the split design of the first waterway plate 4 and the second waterway plate 5.

[0058] In a specific embodiment, the water supply system 2 for the water supply device may further include a pump body 81, and the circulation path may further include a third medium channel 82 and a fourth medium channel 83. The third medium channel 82 connects the second medium channel 51 and the pump body 81, and the fourth medium channel 83 connects the pump body 81 and the heat tank 6. The pump body 81 is used to pump the heat exchange medium in the fourth medium channel 83 to the third medium channel 82, and the heat tank 6 is arranged in the frame 9 and below the first waterway plate 4.

[0059] In the structure provided in this specific embodiment, due to the relative positional relationship between the first waterway plate 4 and the heat tank 6, the heat exchange medium in the heat tank 6 is difficult to spontaneously enter the first waterway plate 4 under the action of gravity. Therefore, by providing the third medium channel 82, the fourth medium channel 83 and the pump body 81, the pump body 81 can be used to provide power to the heat exchange medium, thereby urging the heat exchange medium to circulate between the heat tank 6, the first waterway plate 4, the second waterway plate 5, and the heat exchanger 3, so as to achieve the purpose of using the heat exchange medium to exchange heat with the water body.

[0060] Optionally, the circulation passage may further include a second drainage pipe 821, the second drainage pipe 821 is connected between the first waterway plate 4 and the second waterway plate 5, and at least part of the third medium channel 82 is disposed in the second drainage pipe 821. The heat exchange medium extracted from the heat tank 6 by the pump body 81 can flow to the second medium channel 51 of the second waterway plate 5 through the second drainage pipe 821, and then can enter the medium heat exchange channel 32 through the medium inlet 321 at the bottom of the heat exchanger 3.

[0061] Optionally, the circulation path may further include a fourth drainage pipe 831, one end of which is connected to the fourth medium channel 83, and the other end is disposed in the heat exchange medium at the upper end of the hot tank 6. For the same substance, the part with a higher temperature will naturally move to the upper layer, while the part with a lower temperature will remain at the bottom layer. When the pump body 81 is working, the fourth drainage pipe 831 located at the upper layer of the hot tank 6 can draw the heat exchange medium with a higher temperature in the hot tank 6 into the fourth medium channel 83, so as to enter the third medium channel 82 through the medium channel, so that this part of the heat exchange medium can be input into the heat exchanger 3 for the heat exchange process.

[0062] In a specific embodiment of the present application, the water supply system 2 for the water supply device may further include a heating device 7 , and the water supply passage may further include a fourth water supply channel 71 disposed on the heating device 7 .

[0063] Optionally, the fourth water supply channel 71 is connected between the second water supply channel 52 and the third water supply channel 43. Thus, the water flowing out of the second water supply channel 52 can enter the fourth water supply channel 71 to be heated by the heating device 7, and then enter the subsequent water supply passage through the third water supply channel 43 to be output outside the water supply system 2 for the water supply device.

[0064] Optionally, the fourth water supply channel 71 is connected between the second water supply channel 52 and the water supply heat exchange channel 31. Thus, the water flowing out of the water supply heat exchange channel 31 can enter the fourth water supply channel 71 to be heated by the heating device 7, and then enter the subsequent water supply passage through the second water supply channel 52 to be output outside the water supply system 2 for the water supply device.

[0065] In the structure provided in this specific embodiment, by adding a fourth water supply channel 71 and a heating device 7, the water flowing out of the heat exchanger 3 and completing the heat exchange process can be further heated. When the water body cannot be raised to a temperature that meets the requirements by heat exchange alone, the heating device 7 can be used to further increase the temperature and quickly raise the water body to a temperature that meets the requirements.

[0066] Through the cooperation of the heat exchanger 3, the hot tank 6 and the heating device 7, the hot tank 6 can be used to store energy during idle time. When the water body needs to be heated, this part of energy can be released by using the heat exchanger 3, and the heating device 7 only needs to perform further heating on the basis of heat exchange, so that the energy during idle time can be utilized, the working efficiency of the water supply system 2 used for the water supply device can be improved, and the power demand for the heating device 7 when the water body heats up rapidly can be effectively reduced.

[0067] Optionally, when the heating device 7 is connected between the second water supply channel 52 and the third water supply channel 43, the heating device 7 can be vertically arranged parallel to the first side surface 91, so as to save installation space and help reduce the volume of the water supply device 1. One end of the heating device 7 can be directly connected to the second waterway plate 5.

[0068] Alternatively, if Figure 6 to Figure 8 As shown, the water supply passage may further include a first drainage pipe 72 , in which at least part of the fourth water supply channel 71 is disposed. One end of the first drainage pipe 72 is connected to the heating device 7 , and the other end is connected to the third water supply channel 43 of the first waterway plate 4 .

[0069] To solve the above technical problems, a specific embodiment of the present application may provide a water supply device 1, comprising a body and a water supply system 2 for the water supply device as described in any of the above specific embodiments, and the body is connected to the water supply system 2 for the water supply device.
