[0028] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0031] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0032] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention. Among them, the dotted line in the accompanying drawings indicates the flow direction of water in the pipeline.

[0033] A water supply device can usually provide drinking water at at least two temperatures. In the related art, the water supply device is equipped with a corresponding water flow channel for each temperature of drinking water, which results in a large number of water flow channels, a large occupied space, and it is also troublesome to disinfect each water flow channel.

[0034] In view of this, the present invention provides a waterway plate and a water supply device, which use the same water flow channel to transport drinking water of different temperatures, thereby simplifying the setting of the water flow channel and also simplifying the disinfection of the water flow channel.

[0035] like Figures 1 to 3 As shown, the waterway plate 100 provided in the embodiment of the present invention comprises a first water delivery channel 10, wherein the first water delivery channel 10 is provided with a water outlet 11, a first input part 12 and a second input part 13, wherein the water outlet 11 is used to connect to a water-using device, and the first input part 12 and the second input part 13 are both used to supply water to flow into the first water delivery channel 10. The water-using device may be a faucet.

[0036] By adopting the above technical solution, by setting two input parts, namely the first input part 12 and the second input part 13, water of different temperatures can be input respectively through the two input parts, and the first water delivery channel 10 can deliver water of different temperatures. Therefore, one water flow channel can provide two kinds of water of different temperatures for the water-using equipment, which simplifies the design of the water flow channel for delivering water of different temperatures and is conducive to the miniaturization of the water supply device.

[0037] In one embodiment, the first input portion 12 is used to supply normal temperature water to flow into the first water transfer channel 10, and the second input portion 13 is used to supply hot water or sterilizing water to flow into the first water transfer channel 10. Therefore, the first water transfer channel 10 can not only transport normal temperature water to the water-using equipment, but also transport hot water to the water-using equipment, and can also transport sterilizing water to sterilize the pipeline. Among them, by enabling the first water transfer channel 10 to transport hot water, the hot water can sterilize the pipeline at high temperature when flowing through the first water transfer channel 10. In specific implementation, the first input portion 12 can be used to connect the water flow channel that transports normal temperature water, so that the normal temperature water can flow through the first input portion 12 into the first water transfer channel 10; the second input portion 13 can be used to connect to a hot water generating device that generates hot water, so that the hot water can flow through the second input portion 13 into the first water transfer channel 10.

[0038] In one embodiment, the first input portion 12 and the second input portion 13 are both arranged upstream of the water outlet portion 11, and the second input portion 13 is arranged upstream of the first input portion 12. That is to say, the first input portion 12 and the water outlet portion 11 are both arranged downstream of the second input portion 13. Therefore, when hot water flows through the first water transfer channel 10, it can flow through the entire first water transfer channel 10. During the flow of hot water, the pipeline will be sterilized at high temperature at the same time. By setting the hot water to flow through the entire first water transfer channel 10, the sterilization and disinfection of the entire first water transfer channel 10 can be achieved. However, the present application transports normal temperature water and hot water through the first water transfer channel 10, so when the first water transfer channel 10 is disinfected, the water flow channels that transport normal temperature water and hot water are disinfected at the same time, which simplifies the disinfection operation and greatly improves the disinfection efficiency.

[0039] See also Figure 2 The waterway plate 100 also includes a water replenishment channel 20, which is used to connect to the water demanding device to replenish water for the water demanding device. By arranging both the water replenishment channel 20 and the first water delivery channel 10 on the waterway plate 100, the integration of the waterway plate 100 is improved, which is conducive to the miniaturization of the water supply device.

[0040] See also Figure 1 and Figure 2 The first water delivery channel 10 is also provided with a water replenishment portion 14, and the water replenishment channel 20 is connected to the water replenishment portion 14. In this way, the water in the first water delivery channel 10 flows into the water replenishment channel 20 through the water replenishment portion 14 to replenish the water demanding device.

[0041] Among them, the water-demanding device can be a hot water tank 300 and / or an ice tank (not shown). The hot water tank 300 is used to store and heat the heat exchange medium. The heat exchange medium is used to flow back into the hot water tank 300 after heat exchange with the drinking water in the heat exchanger 200 when flowing through the heat exchanger 200. When the heat exchange medium is water, steam will be generated after the water is heated. In order to avoid increasing the air pressure in the hot water tank 300, the steam needs to be discharged from the hot water tank 300, and the amount of water in the hot water tank 300 will decrease, so it is necessary to replenish the water to the hot water tank 300 regularly or irregularly. The ice tank is used to cool the water flowing through to generate cold water. In specific applications, the ice tank is connected to the water-using equipment to provide cold water to the water-using equipment. Therefore, the amount of water in the ice tank will decrease, so it is necessary to replenish the water to the ice tank regularly or irregularly. By setting a water replenishment channel 20 to connect the water replenishment part 14, it is possible to replenish water for the hot water tank 300 and / or the ice tank.

[0042] In one embodiment, the water replenishment portion 14 is disposed downstream of the first input portion 12. Since the second input portion 13 is located upstream of the first input portion 12, the water replenishment portion 14 is disposed downstream of the first input portion 12 and the second input portion 13. Therefore, the first water delivery channel 10 can deliver both normal temperature water and hot water to the water demanding device.

[0043] In specific applications, it is possible to choose to deliver normal temperature water or hot water to the water-demanding device according to different scenarios. For example, when the water-demanding device includes a hot water tank 300, it is possible to choose to deliver normal temperature water to the hot water tank 300 for water replenishment, or to choose to deliver hot water to the hot water tank 300 for water replenishment. When the water-demanding device includes an ice tank, it is possible to choose to deliver normal temperature water to the ice tank for water replenishment, or to choose to deliver hot water to the ice tank for sterilization and disinfection.

[0044] It is understandable that in other embodiments, the water replenishment portion 14 may be disposed between the first input portion 12 and the second input portion 13. When this technical solution is adopted, the first water delivery channel 10 can deliver hot water to the water demanding device.

[0045] See also Figure 2 and Figure 4 The water replenishment channel 20 includes a first water replenishment branch 21 and a second water replenishment branch 22. The first water replenishment branch 21 is used to connect with the hot water tank 300, and the second water replenishment branch 22 is used to connect with the ice tank. When this technical solution is adopted, the water demanding device includes the hot water tank 300 and the ice tank, that is, the hot water tank 300 and the ice tank are both water demanding devices.

[0046] In a specific application, it is possible to first refill the ice container with water, and then refill the hot water tank 300 with water after the ice container is full. In this way, it is possible to prevent the hot water in the hot water tank 300 from flowing into the ice container after the hot water tank 300 is full.

[0047] In one embodiment, the waterway plate 100 is further provided with a valve body (not shown) for preventing water from flowing from the hot water tank 300 to the ice tank. In this way, the hot water in the hot water tank 300 cannot flow into the ice tank, which can prevent the hot water in the hot water tank 300 from flowing into the ice tank due to overfilling, thereby increasing the energy consumption of the ice tank. In a specific application, the valve body can be a check valve connected to the first water replenishment branch 21. A check valve is set in the first water replenishment branch 21, and the resistance of the second water replenishment branch 22 is less than the resistance of the first water replenishment branch 21. The water first flows through the second water replenishment branch 22 to replenish the ice tank. After the ice tank is filled, the water flows through the first water replenishment branch 21 to replenish the hot water tank 300.

[0048] See also Figure 2 and Figure 3 The waterway plate 100 is also provided with a first valve body 31 and a second valve body 32. The first valve body 31 is used to control the connection or disconnection between the first water delivery channel 10 and the water-using equipment, and the second valve body 32 is used to control the connection or disconnection between the first water delivery channel 10 and the water replenishment channel 20.

[0049] In specific implementation, when the first valve body 31 is opened and the second valve body 32 is closed, the first water transfer channel 10 is connected to the water-using equipment and is disconnected from the water replenishment channel 20, so that the water flow in the first water transfer channel 10 can be delivered to the water-using equipment; when the first valve body 31 is closed and the second valve body 32 is opened, the first water transfer channel 10 is connected to the water replenishment channel 20 and is disconnected from the water-using equipment, so that the water flow in the first water transfer channel 10 can be delivered to the water replenishment channel 20.

[0050] In one embodiment, the water replenishment portion 14 is disposed upstream of the water outlet portion 11, the first valve body 31 is connected to the first water delivery channel 10 and is located between the water outlet portion 11 and the water replenishment portion 14, and the second valve body 32 is connected between the water replenishment portion 14 and the water replenishment channel 20. It can be understood that in other embodiments, the water replenishment portion 14 can also be disposed downstream of the water outlet portion 11.

[0051] In one embodiment, the first valve body 31 and the second valve body 32 are both disposed above the first water delivery channel 10, and the water replenishment channel 20 is disposed below the first water delivery channel 10. In this arrangement, the space of the waterway plate 100 in the height direction can be utilized to improve the integration of the waterway plate 100, which is conducive to the miniaturized design of the water supply device.

[0052] See also Figure 1 and Figure 2The waterway plate 100 also includes a second water delivery channel 40, which is provided with a water inlet portion 41 and a first output portion 42. The water inlet portion 41 is used to connect to a water source, and the first output portion 42 is connected to the first input portion 12, so that normal temperature water can flow from the second water delivery channel 40 into the first water delivery channel 10. Among them, the second water delivery channel 40 is a water flow channel for delivering normal temperature water. In this way, normal temperature water can be delivered to the first water delivery channel 10. In addition, the second water delivery channel 40 is arranged on the waterway plate 100, which further improves the integration of the waterway plate 100 and helps to reduce the occupied space of the water supply device.

[0053] In one embodiment, the water source is purified water filtered through a reverse osmosis membrane.

[0054] See also Figure 1 and Figure 2 The waterway plate 100 further includes a one-way valve 35, which is used to allow water to flow from the second water transfer channel 40 to the first water transfer channel 10 in one direction. Since hot water flows through the first input portion 12 and may flow into the second water transfer channel 40, the one-way valve 35 can be provided to prevent hot water from flowing from the first water transfer channel 10 to the second water transfer channel 40.

[0055] See also Figure 1 and Figure 2 The waterway plate 100 further includes a bridge channel 50, which is connected between the first output portion 42 and the first input portion 12, so as to achieve the communication between the first water channel 10 and the second water channel 40. By providing the bridge channel 50, on the one hand, the communication between the first water channel 10 and the second water channel 40 can be achieved, and on the other hand, the flexibility of the first water channel 10 and the second water channel 40 can be improved.

[0056] See also Figure 2 The bridge channel 50 includes a first bridge branch 51 and a second bridge branch 52 connected to each other, the first bridge branch 51 is connected to the second water channel 40, and the second bridge branch 52 is connected to the first water channel 10. In a specific application, water flows from the second water channel 40 through the first bridge branch 51 and the second bridge branch 52 in sequence, and flows into the first water channel 10.

[0057] In one embodiment, the first bridge branch 51 and the second bridge branch 52 both extend in the height direction of the waterway plate 100, perpendicular to the extension direction of the first water channel 10 and the second water channel 40, and the first bridge branch 51 and the second bridge branch 52 partially overlap, so that the first bridge branch 51 and the second bridge branch 52 are connected. In order to improve the integration of the waterway plate 100, the interval between the second water channel 40 and the first water channel 10 is small, and the waterway plate 100 is usually provided with a corresponding valve body to control the on-off state between the water channels. By providing the first bridge branch 51 and the second bridge branch 52 to extend in the height direction of the waterway plate 100, the space in the height direction of the waterway plate 100 can be utilized to achieve the connection between the second water channel 40 and the first water channel 10 in the narrow interval between the second water channel 40 and the first water channel 10, and facilitate the setting of the valve body.

[0058] See also Figure 1 , Figure 4 and Figure 5 , the second water delivery channel 40 is also provided with a second output portion 43, and the second output portion 43 is used to connect to the hot water generating device. Specifically, the second output portion 43 is connected to the water inlet end of the hot water generating device, so that the second water delivery channel 40 can deliver normal temperature drinking water to the hot water generating device. Therefore, the second water delivery channel 40 can not only deliver normal temperature water to the first water delivery channel 10, but also deliver drinking water to the heat exchanger 200, thereby improving the utilization rate of the second water delivery channel 40. According to different scenarios, it can be selected to deliver normal temperature water to the first water delivery channel 10, or to deliver drinking water to the heat exchanger 200, and then to deliver hot water to the first water delivery channel 10. It can be understood that in other embodiments, the second water delivery channel 40 may not be connected to the heat exchanger 200, and other pipelines can be used to deliver drinking water to the heat exchanger 200.

[0059] See also Figures 1 to 4 The waterway plate 100 further includes a third valve body 33 and a fourth valve body 34. The third valve body 33 is used to control the connection or disconnection between the first output portion 42 and the first input portion 12, that is, to control the connection or disconnection between the second water delivery channel 40 and the first water delivery channel 10. The fourth valve body 34 is used to control the connection or disconnection between the second output portion 43 and the heat exchanger 200, that is, to control the connection or disconnection between the second water delivery channel 40 and the heat exchanger 200.

[0060] In specific implementation, when the third valve body 33 is opened and the fourth valve body 34 is closed, the second water supply channel 40 is connected to the first water supply channel 10 and is disconnected from the heat exchanger 200, thereby realizing the delivery of normal temperature water to the first water supply channel 10; when the third valve body 33 is closed and the fourth valve body 34 is opened, the second water supply channel 40 is connected to the heat exchanger 200 and is disconnected from the first water supply channel 10, thereby realizing the provision of drinking water to the heat exchanger 200.

[0061] In one embodiment, the third valve body 33 is connected between the first output portion 42 and the first bridge branch 51. In this way, the third valve body 33 is arranged close to the second water transfer channel 40, which can avoid occupying the space around the first water transfer channel 10, and is conducive to the arrangement of the first valve body 31 and the second valve body 32. Of course, in a specific application, as an alternative implementation scheme, the third valve body 33 can also be connected between the second bridge branch 52 and the first water transfer channel 10.

[0062] In one embodiment, the third valve body 33 and the fourth valve body 34 are both disposed above the second water conveying channel 40 and the first water conveying channel 10. In this way, the space of the waterway plate 100 in the thickness direction can be effectively utilized, and the integration of the waterway plate 100 can be improved.

[0063] In one embodiment, the first water conveying channel 10 and the second water conveying channel 40 are arranged adjacent to each other and both extend along the first direction X, wherein the first direction X is the length direction of the waterway plate 100, and the waterway plate 100 includes a first end 100a and a second end 100b opposite to each other along the first direction. The water outlet portion 11, the first input portion 12 and the second input portion 13 are sequentially arranged in the first water conveying channel 10 along the direction from the first end 100a to the second end 100b, that is, the water flows in the first water conveying channel 10 along the direction from the second end 100b to the first end 100a. The water inlet portion 41, the first output portion 42 and the second output portion 43 are sequentially arranged in the second water conveying channel 40 along the direction from the first end 100a to the second end 100b, that is, the water flows in the second water conveying channel 40 along the direction from the first end 100a to the second end 100b. The first input portion 12 and the first output portion 42 are arranged correspondingly. Such an arrangement also facilitates the arrangement of the bridging channel 50, and the second input portion 13 and the second output portion 43 are both connected to the hot water generating device. By arranging them both near the second end 100b, it is beneficial to arrange the hot water generating device.

[0064] See also Figure 1 The waterway plate 100 also includes a flow meter 37, which is arranged on the side of the second water delivery channel 40 close to the first water delivery channel 10, and is used to connect the second output part 43 and the hot water generating device. The second input part 13 is located below the flow meter 37. The flow meter 37 is used to detect the water flow rate. The hot water generating device can heat the water body according to the water flow rate detected by the flow meter 37 and the water body temperature detected by the temperature sensor to generate hot water that meets the requirements. The second input part 13 is arranged below the flow meter 37 to avoid the valve body arranged above, so that the second input part 13 is conveniently connected to the hot water generating device.

[0065] See also Figure 3, the waterway plate 100 also includes a third water delivery channel 60 and a fourth water delivery channel 70. The third water delivery channel 60 is used to connect the water-using equipment and the fourth water delivery channel 70, and discharge the water flow from the water-using equipment to the fourth water delivery channel 70. The fourth water delivery channel 70 is used to discharge the water flow, that is, to discharge the waste water from the water-using equipment. In the related art, when changing from one water supply mode to another water supply mode, since a certain amount of water in the previous water supply mode is stored in the pipeline at the water-using equipment, it is necessary to release the water in the water-using equipment from the water-using equipment before the water in the replaced water supply mode is supplied. For example, when changing from the hot water supply mode (the first water delivery channel 10 delivers hot water to the water-using equipment) to the normal temperature water supply mode (the first water delivery channel 10 delivers normal temperature water to the water-using equipment), since a certain amount of hot water is stored in the pipeline at the water-using equipment, it is necessary to release the hot water in the water-using equipment from the water-using equipment before the normal temperature water is supplied, which brings a bad user experience. By providing the third water delivery channel 60 and the fourth water delivery channel 70, when the water supply mode is changed, the water in the previous water supply mode can flow back into the third water delivery channel 60 and then be discharged through the fourth water delivery channel 70, and there is no need to discharge the water in the previous water supply mode from the water-using equipment, which greatly improves the user experience. In addition, after the sterilizing water used for sterilization is delivered to the pipeline at the water-using equipment, it can also flow back into the third water delivery channel 60 and then be discharged through the fourth water delivery channel 70 to avoid the sterilizing water flowing out of the water-using equipment.

[0066] In this embodiment, the third water conveying channel 60 and the fourth water conveying channel 70 are provided on the waterway plate 100 , so as to improve the integration of the waterway plate 100 , which is beneficial to reducing the occupied space of the water supply device.

[0067] In this embodiment, the third water channel 60 and the fourth water channel 70 are arranged adjacent to each other and both extend along the first direction X. The water outlet portion 11 of the first water channel 10, the water inlet portion 41 of the second water channel 40, the water inlet end of the third water channel 60 and the water outlet end of the fourth water channel 70 are all arranged at the first end 100a of the waterway plate 100. In addition, the second water channel 40, the first water channel 10, the third water channel 60 and the fourth water channel 70 are arranged in sequence from the third end 100c to the fourth end 100d of the waterway plate along the second direction Y. The second direction Y is the width direction of the waterway plate 100.

[0068] See also Figure 1 and Figure 3 The waterway plate 100 further includes a pump body 36, which is connected to the fourth water delivery channel 70 and is used to provide power for the flow of water in the fourth water delivery channel 70. In a specific application, when the water supply mode is changed, the pump body 36 can be turned on to suck the water at the water equipment back into the fourth water delivery channel 70.

[0069] In one embodiment, the water channels of the waterway plate 100 are integrally formed, so as to improve the connection sealing performance between the water channels and prevent water leakage in the water channels.

[0070] See also Figure 4 The embodiment of the present invention further provides a water supply device, including the above-mentioned waterway plate 100. By adopting the above-mentioned waterway plate 100, two water bodies of different temperatures can be provided to the water-using equipment through one water flow channel, which simplifies the design of the water flow channel, is conducive to the miniaturization development of the water supply device, and also simplifies the disinfection of the water flow channel that transports water bodies of different temperatures.

[0071] The water supply device also includes a hot water generating device for generating hot water, and the hot water generating device is connected to the second input part 13 to deliver the generated hot water to the second input part 13. The hot water generating device includes a heat exchanger 200 and a hot water tank 300, the heat exchanger 200 is provided with a first heat exchange channel and a second heat exchange channel isolated from each other, a heat exchange medium is provided in the hot water tank 300, and the hot water tank 300 is connected with the second heat exchange channel so that the heat exchange medium can be heat exchanged with the drinking water in the first heat exchange channel in the second heat exchange channel and then flow back into the hot water tank 300; the second input part 13 is connected to the water outlet end of the first heat exchange channel.

[0072] Among them, the heat exchange medium can be water or heat transfer oil. When the heat exchange medium is water, the hot water tank 300 can be connected to the water replenishment channel 20, and the hot water tank 300 is replenished with water through the water replenishment channel 20; when the heat exchange medium is heat transfer oil, the hot water tank 300 is not connected to the water replenishment channel 20.

[0073] See also Figure 1 , Figure 2 and Figure 5The first heat exchange channel is provided with a first input port 201 and a first output port 202, and the second heat exchange channel is provided with a second input port 203 and a second output port 204. The first heat exchange channel and the second heat exchange channel are adjacent and isolated. The first input port 201 is used for drinking water to flow into the first heat exchange channel, that is, for drinking water before heating to flow into the heat exchanger 200, and the first output port 202 is used for drinking water to flow out of the first heat exchange channel, that is, for drinking water after heating to flow out of the heat exchanger 200, and the first heat exchange channel is used for drinking water to flow through. The second input port 203 is used for heat exchange medium to flow into the second heat exchange channel, that is, to flow into the heat exchanger 200, and the second output port 204 is used for heat exchange medium to flow out of the second heat exchange channel, that is, to flow out of the heat exchanger 200, and the second heat exchange channel is used for heat exchange medium to flow through. When the heat exchange medium and normal temperature drinking water are controlled to flow through the heat exchanger 200 at the same time, heat exchange is performed between the two, so that normal temperature drinking water generates hot drinking water. In the present application, the second input portion 13 of the first water delivery channel 10 is connected to the first output port 202, that is, the water outlet of the first heat exchange channel, and the second output portion 43 of the second water delivery channel 40 is connected to the first input port 201, that is, the water inlet of the first heat exchange channel.

[0074] See also Figure 5 and Figure 6 The hot water tank 300 is provided with a discharge port 301 and a reflux port 302. The discharge port 301 and the second input port 203 of the heat exchanger 200 are connected through a pipeline, and the reflux port 302 and the second output port 204 of the heat exchanger 200 are connected through a pipeline, thereby realizing that the medium channel of the hot water tank 300 is connected with the heat exchanger 200.

[0075] like Figure 5 and Figure 6 As shown, the hot water tank 300 is further provided with a water replenishment port 303 , and the water replenishment channel 20 is connected to the water replenishment port 303 to replenish water for the hot water tank 300 .

[0076] See also Figures 3 to 5 The hot water generating device further includes a heater 400, which is used to heat the water flowing through. The heater 400 may be a thick film heating device, which instantly heats the water flowing through. In a specific application, the heater 400 is connected between the water outlet of the first heat exchange channel and the second input portion 13. Specifically, the water inlet of the heater 400 is connected to the first output port 202 of the heat exchanger 200, and the water outlet of the heater 400 is connected to the second input portion 13 of the first water transfer channel 10.

[0077] By arranging the heat exchanger 200 and the heater 400 to heat the drinking water, the heating effect of the drinking water can be improved, and a large flow of drinking hot water can be achieved. The drinking hot water does not need to be heated and stored in advance, that is, the output water is "fresh" hot water.

[0078] In this embodiment, the hot water generating device includes a heat exchanger 200, a hot water tank 300 and a heater 400. It is understood that in other embodiments, the water supply device may not be provided with a heater 400, or the hot water generating device may not be provided with a heat exchanger 200 and a hot water tank 300.

[0079] When the waterway plate 100 is used to provide hot water for water-using equipment, the first valve body 31 and the fourth valve body 34 are controlled to be opened, and the second valve body 32 and the third valve body 33 are closed. Normal temperature water flows into the second water transfer channel 40 through the water inlet portion 41 of the second water transfer channel 40, and then flows to the heat exchanger 200 and the heater 400 through the second output portion 43 of the second water transfer channel 40. After hot water is generated, it flows into the first water transfer channel 10 through the second input portion 13 of the first water transfer channel 10, and flows to the water-using equipment through the water outlet portion 11 of the first water transfer channel 10.

[0080] When the water circuit board 100 is used to provide hot water for the water-demanding device, the second valve body 32 and the fourth valve body 34 are controlled to be opened, and the first valve body 31 and the third valve body 33 are closed. Normal temperature water flows into the second water transfer channel 40 through the water inlet portion 41 of the second water transfer channel 40, and then flows to the heat exchanger 200 and the heater 400 through the second output portion 43 of the second water transfer channel 40. After hot water is generated, it flows into the first water transfer channel 10 through the second input portion 13 of the first water transfer channel 10, and flows into the second water replenishment branch 22 through the water replenishment portion 14 of the first water transfer channel 10 to replenish water for the ice tank. When the ice tank is filled with water or the ice tank is replenished with water to a preset water level, the water flows through the water replenishment portion 14 of the first water transfer channel 10 into the first water replenishment branch 21 to replenish water for the hot water tank 300.

[0081] When the waterway plate 100 is used to provide normal temperature water for water-using equipment, the first valve body 31 and the third valve body 33 are controlled to be open, and the second valve body 32 and the fourth valve body 34 are controlled to be closed. Normal temperature water flows into the second water transfer channel 40 through the water inlet portion 41 of the second water transfer channel 40, and then flows to the bridge pipe through the first output portion 42 of the second water transfer channel 40, and then flows into the first water transfer channel 10 through the first input portion 12 of the first water transfer channel 10, and flows to the water-using equipment through the water outlet portion 11 of the first water transfer channel 10.

[0082] When the water circuit plate 100 is used to provide normal temperature water for the water-demanding device, the second valve body 32 and the third valve body 33 are controlled to be opened, and the first valve body 31 and the fourth valve body 34 are closed. The normal temperature water flows into the second water transfer channel 40 through the water inlet part 41 of the second water transfer channel 40, and then flows to the bridge pipe through the first output part 42 of the second water transfer channel 40, and then flows into the first water transfer channel 10 through the first input part 12 of the first water transfer channel 10, and flows into the second water replenishment branch 22 through the water replenishment part 14 of the first water transfer channel 10 to replenish water for the ice tank. When the ice tank is filled with water or the ice tank is replenished with water to a preset water level, the water flows through the water replenishment part 14 of the first water transfer channel 10 into the first water replenishment branch 21 to replenish water for the hot water tank 300.
