[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] It should be noted that, in the present application, the first direction X refers to the length direction of the waterway plate, the second direction Y refers to the width direction of the waterway plate, and the third direction Z refers to the height direction of the waterway plate. The dotted lines in the drawings indicate the flow direction of water in the pipeline.

[0040] like Figures 1 to 5 As shown, the water circuit board 100 provided in the embodiment of the present invention includes a water supply pipeline 10, a water inlet pipeline 20 and a water outlet pipeline 30. The water inlet pipeline 20 is used to connect to a water source, and the water outlet pipeline 30 is used to connect to a water end (such as a faucet). The water inlet pipeline 20 and the water outlet pipeline 30 both extend along a first direction X; at least part of the water supply pipeline 10 extends along a second direction Y and connects to the water outlet pipeline 30, so as to supply water to the water demanding device 200. The water circuit board 100 also includes a bridge pipeline 40, which extends along the second direction Y or along the third direction Z and is connected between the water inlet pipeline 20 and the water outlet pipeline 30. By connecting to the water source through the water inlet pipeline 20, normal temperature water can be introduced into the water circuit board 100, and through the bridge pipeline 40 and the water outlet pipeline 30, the normal temperature water can be transported to the water supply pipeline 10. Among them, the water source can be purified water filtered by an RO membrane. When in use, normal temperature water enters the waterway plate 100 from the water inlet pipe 20, then flows into the water replenishment pipe 10 through the bridge pipe 40 and the water outlet pipe 30 in sequence, and then flows into the water demanding device 200, so as to replenish the water demanding device 200 with normal temperature water.

[0041] By adopting the above technical solution, by setting the water supply pipeline 10, the water inlet pipeline 20, the water outlet pipeline 30 and the bridge pipeline 40, it is possible to replenish the water demand device 200 with normal temperature water, which can reduce energy waste compared to the technical solution of replenishing hot water. By setting the water supply pipeline 10, the water inlet pipeline 20, the water outlet pipeline 30 and the bridge pipeline 40 on the waterway plate 100, the integration of the pipeline for replenishing water for the water demand device 200 is improved, the space occupied by the pipeline is reduced, and it is helpful for the miniaturization design of the water supply device. In addition, by setting the bridge pipeline 40 to connect the water inlet pipeline 20 and the water outlet pipeline 30, the water inlet pipeline 20 and the water outlet pipeline 30 are connected.

[0042] In one embodiment, the water inlet pipeline 20 and the water outlet pipeline 30 are arranged adjacent to each other along the second direction Y. Such an arrangement improves the compactness of the pipeline.

[0043] In one embodiment, the bridge pipe 40 includes at least one bridge branch pipe, and at least one bridge branch pipe extends along the third direction Z. In order to improve the integration of the waterway plate 100, the interval between the water inlet pipe 20 and the water outlet pipe 30 is small, and the waterway plate 100 is usually provided with a corresponding valve body to control the on-off state between the pipes. By arranging each bridge branch pipe to extend along the third direction Z, which is the height direction of the waterway plate 100, the space of the waterway plate 100 in the height direction can be utilized, and the water inlet pipe 20 and the water outlet pipe 30 can be connected in the narrow interval between the water inlet pipe 20 and the water outlet pipe 30, and the valve body is conveniently arranged, and it is beneficial to reduce the space occupied by the waterway plate 100 in the horizontal direction.

[0044] See also Figures 2 to 4 The bridge pipe 40 includes two bridge branches, which are defined as a first bridge branch 41 and a second bridge branch 42. The first bridge branch 41 and the second bridge branch 42 extend along the third direction Z and partially overlap. The first bridge branch 41 is connected to the water inlet pipe 20, and the second bridge branch 42 is connected to the water outlet pipe 30. In a specific application, water flows from the water inlet pipe 20 through the first bridge branch 41 and the second bridge branch 42 in sequence and flows into the water outlet pipe 30.

[0045] See also Figure 1 and Figure 2 , the waterway plate 100 also includes a first control valve 51, which is connected between the water inlet pipeline 20 and the first bridge branch pipe 41, and is used to control the on and off of the bridge pipe 40. Specifically, the water inlet of the first control valve 51 is connected to the water inlet pipeline 20, and the water outlet of the first control valve 51 is connected to the first bridge branch pipe 41. The first control valve 51 is used to control the connection or disconnection of the water inlet pipeline 20 and the bridge pipe 40. In this way, the connection or disconnection of the water inlet pipeline 20 and the water outlet pipeline 30 can be controlled. In specific implementation, when the first control valve 51 is opened, the water inlet pipeline 20 and the bridge pipe 40 are connected, and normal temperature water can flow into the water outlet pipeline 30 through the bridge pipe 40; when the first control valve 51 is closed, the water inlet pipeline 20 and the bridge pipe 40 are disconnected, and normal temperature water cannot flow from the water inlet pipeline 20 into the water outlet pipeline 30.

[0046] It can be understood that in other embodiments, the first control valve 51 can also be connected between the water outlet pipeline 30 and the second bridge branch pipe 42. When this technical method is adopted, the water inlet of the first control valve 51 is connected to the second bridge branch pipe 42, and the water outlet of the first control valve 51 can also be connected to the water outlet pipeline 30. The first control valve 51 is used to control the connection or disconnection of the water outlet pipeline 30 and the bridge pipeline 40. In this way, the connection or disconnection of the water inlet pipeline 20 and the water outlet pipeline 30 can also be controlled.

[0047] In one embodiment, the first control valve 51 and the bridge pipe 40 are respectively arranged on both sides of the waterway plate 100 along the height direction of the waterway plate 100. In this way, the space of the waterway plate 100 in the height direction can be fully utilized, and the integration of the waterway plate 100 is greatly improved. In this embodiment, the first control valve 51 is arranged on the upper side of the waterway plate 100, and the bridge pipe 40 is arranged on the lower side of the waterway plate 100. It can be understood that in other embodiments, the first control valve 51 can also be arranged on the lower side of the waterway plate 100, and the bridge pipe 40 can also be arranged on the upper side of the waterway plate 100.

[0048] In one embodiment, one of the first bridging branch pipe 41 and the second bridging branch pipe 42 is provided with a plugging port 421, and the waterway plate 100 further includes a plugging member 55, and the plugging member 55 is used to seal the plugging port 421. In a specific application, when the first bridging branch pipe 41 is connected to the first control valve 51, the second bridging branch pipe 42 is provided with a plugging port 421; when the second bridging branch pipe is connected to the first control valve 51, the first bridging branch pipe 41 is provided with a plugging port 421. Among them, the plugging port 421 communicates with the outside and the cavity of the corresponding pipeline, and at least the part of the pipeline close to the plugging port 421 extends along the axial direction of the plugging port 421. During the injection molding process of the pipeline, the mold can be directly removed along the axial direction of the plugging port 421. During the assembly process, the plugging port 421 is sealed by the plugging member 55 to form a preset water flow channel, the processing difficulty of the pipeline is reduced, and the production efficiency is improved. In this embodiment, the plugging port 421 is provided in the second bridging branch pipe 42. In addition, the first bridging branch pipe 41 and the second bridging branch pipe 42 extend along the third direction Z, and the sealing port 421 and the plugging piece 55 are correspondingly arranged above or below the waterway plate 100, which can avoid side congestion caused by arranging the sealing port 421 and the plugging piece 55 on the side of the waterway plate 100.

[0049] In one embodiment, the waterway plate 100 includes a first end 100a and a second end 100b arranged opposite to each other along a first direction. The portion of the water outlet pipe 30 used to connect to the water end, the portion of the water outlet pipe 30 connected to the water supply pipe 10, and the portion of the water outlet pipe 30 connected to the bridge pipe 40 are arranged in sequence in the water outlet pipe 30 along the direction from the first end 100a to the second end 100b, that is, the water flow in the water outlet pipe 30 flows along the direction from the second end 100b to the first end 100a. The portion of the water inlet pipe 20 used to connect to the water source and the portion of the water inlet pipe 20 connected to the bridge pipe 40 are arranged in the water inlet pipe 20 along the direction from the first end 100a to the second end 100b, that is, the water flow in the water inlet pipe 20 flows along the direction from the first end 100a to the second end 100b. The part where the water outlet pipe 30 is connected to the bridge pipe 40 and the part where the water inlet pipe 20 is connected to the bridge pipe 40 are arranged correspondingly. In this way, the bridge pipe 40 can occupy less space of the waterway plate 100.

[0050] In one embodiment, the water outlet pipeline 30 is also used to connect the water treatment device 300 and the water replenishment pipeline 10 to transport hot water to the water replenishment pipeline 10. Specifically, the water outlet pipeline 30 is connected to the drinking water output port 302 of the water treatment device 300. In this way, the water outlet pipeline 30 can not only transport normal temperature water to the water demanding device 200, but also transport hot water to the water demanding device 200. According to different scenarios, it can be selected to transport normal temperature water or hot water to the water demanding device 200. For example, when the water demanding device 200 includes a hot water tank 201, it can be selected to transport normal temperature water to the hot water tank 201 for water replenishment, or it can be selected to transport hot water to the hot water tank 201 for water replenishment. When the water demanding device 200 includes an ice tank, it can be selected to transport normal temperature water to the ice tank for water replenishment, and it can also be selected to transport hot water to the ice tank for sterilization and disinfection.

[0051] In one embodiment, the water demand device 200 includes a hot water tank 201 and an ice tank, and the water supply pipeline 10 includes a first branch 11 and a second branch 12. The first branch 11 is used to supply water to the hot water tank 201, and the second branch 12 is used to supply water to the ice tank. In a specific application, it is possible to first supply water to the ice tank, and then supply water to the hot water tank 201 after the ice tank is full. In this way, the hot water in the hot water tank 201 can be prevented from flowing into the ice tank after the hot water tank 201 is full.

[0052] In one embodiment, the part of the water outlet pipe 30 used to connect to the water treatment device 300 is located upstream of the part where the water outlet pipe 30 is connected to the bridge pipe 40. That is, the part where the water outlet pipe 30 is connected to the water treatment device 300 is close to the second end 100b of the waterway plate. In this way, hot water can flow through the entire water outlet pipe 30, thereby playing a role in hot water sterilization of the water outlet pipe 30. Please refer to Figure 3 and Figure 4The waterway plate 100 further includes a one-way valve 56, which is disposed on the bridge pipe 40 to allow water to flow from the water inlet pipe 20 to the water outlet pipe 30 in one direction. In a specific application, the hot water input portion of the water outlet pipe 30 is located upstream of the connection portion between the water outlet pipe 30 and the bridge pipe 40. When hot water is transported to the water supply pipe 10, the hot water will flow through the connection portion between the water outlet pipe 30 and the bridge pipe 40. By disposing the one-way valve 56 on the bridge pipe 40, it is possible to prevent the hot water from flowing into the water inlet pipe 20 through the bridge pipe 40.

[0053] See also Figure 1 The waterway plate 100 also includes a second control valve 52 and a third control valve 53. The second control valve 52 is used to control the connection or disconnection between the water outlet pipeline 30 and the water use end, and the third control valve 53 is used to control the connection or disconnection between the water outlet pipeline 30 and the water supply pipeline 10.

[0054] In specific implementation, when the second control valve 52 is opened and the third control valve 53 is closed, the water outlet pipeline 30 is connected to the water use end and is disconnected from the water supply pipeline 10, so that the water flow in the water outlet pipeline 30 can be transported to the water use end; when the second control valve 52 is closed and the third control valve 53 is opened, the water outlet pipeline 30 is connected to the water supply pipeline 10 and is disconnected from the water use end, so that the water flow in the water outlet pipeline 30 can be transported to the water supply pipeline 10.

[0055] In one embodiment, the second control valve 52 and the third control valve 53 are both disposed above the water outlet pipe 30. In this way, the integration of the waterway plate 100 is increased, which is beneficial to reducing the occupied space of the waterway plate 100.

[0056] In one embodiment, the connection portion between the water outlet pipeline 30 and the water-using end is arranged downstream of the connection portion between the water outlet pipeline 30 and the water supply pipeline 10, the second control valve 52 is connected to the water outlet pipeline 30 and is located downstream of the connection portion between the water outlet pipeline 30 and the water supply pipeline 10, and the third control valve 53 is connected between the water outlet pipeline 30 and the water supply pipeline 10. It can be understood that in other embodiments, the connection portion between the water outlet pipeline 30 and the water-using end can also be arranged upstream of the connection portion between the water outlet pipeline 30 and the water supply pipeline 10.

[0057] In one embodiment, the water inlet pipeline 20 is also used to connect the water treatment device 300 to deliver drinking water to the water treatment device 300. Specifically, the water inlet pipeline 20 is connected to the drinking water input port 301 of the water treatment device 300. In this way, the water inlet pipeline 20 can not only deliver normal temperature water to the water outlet pipeline 30, but also deliver drinking water to the water treatment device 300, thereby improving the utilization rate of the water inlet pipeline 20. According to different scenarios, it can be selected to deliver normal temperature water to the water outlet pipeline 30, or to deliver drinking water to the water treatment device 300. For example, when it is necessary to replenish water for the hot water tank 201, the water inlet pipeline 20 can be selected to deliver normal temperature water to the water outlet pipeline 30; when it is necessary to deliver hot water to the water end, it can be selected to deliver drinking water to the water treatment device 300, and the drinking water is heat exchanged in the water treatment device 300 to generate hot water, and then delivered to the water outlet pipeline 30. It is understandable that in other embodiments, the water inlet pipeline 20 may not be connected to the water treatment device 300. In this case, other pipelines may be used to transport drinking water to the water treatment device 300.

[0058] See also Figure 1 and Figure 5 The waterway plate 100 also includes a fourth control valve 54, which is used to control the connection or disconnection between the water inlet pipeline 20 and the water treatment device 300. When the fourth control valve 54 is opened, the water inlet pipeline 20 and the water treatment device 300 are connected, and the water inlet pipeline 20 can transport drinking water to the water treatment device 300; when the fourth control valve 54 is closed, the water inlet pipeline 20 and the water treatment device 300 are disconnected.

[0059] During specific implementation, the first control valve 51 can be opened and the fourth control valve 54 can be closed to enable the water inlet pipeline 20 to transport room temperature water to the water outlet pipeline 30; or, the first control valve 51 can be closed and the fourth control valve 54 can be opened to enable the water inlet pipeline 20 to transport drinking water to the water treatment device 300.

[0060] The first control valve 51 , the second control valve 52 , the third control valve 53 and the fourth control valve 54 are all solenoid valves.

[0061] See also Figure 1 , Figure 6 and Figure 7 The waterway plate 100 further includes a heat exchange medium output pipeline 60 and a heat exchange medium return pipeline 70. The heat exchange medium output pipeline 60 is used to connect the medium outlet 2011 of the hot water tank 201 and the medium input port 303 of the water treatment device 300, and the heat exchange medium return pipeline 70 is used to connect the medium return port 2012 of the hot water tank 201 and the medium output port 304 of the water treatment device 300.

[0062] In specific implementation, the heat exchange medium flows into the heat exchange medium output pipeline 60 through the medium discharge port 2011 of the hot water tank 201, and then flows into the water treatment device 300 through the medium input port 303 of the water treatment device 300. After heat exchange with drinking water in the water treatment device 300, it flows into the heat exchange medium return pipeline 70 from the medium output port 304 of the water treatment device 300, and then flows back into the hot water tank 201 through the medium return port 2012 of the hot water tank 201.

[0063] See also Figure 1 and Figure 5 The waterway plate 100 further includes a pump body 57, which is connected to the heat exchange medium output pipeline 60 to provide power for the heat exchange medium to flow between the hot water tank 201 and the water treatment device 300. It can be understood that in other embodiments, the pump body 57 can also be connected to the heat exchange medium return pipeline 70. In specific applications, when the heat exchange medium needs to be output, the pump body 57 can be started to allow the heat exchange medium to flow between the hot water tank 201 and the water treatment device 300, so that the heat exchange medium can exchange heat with the drinking water in the water treatment device 300 when flowing through the water treatment device 300.

[0064] See also Figure 1 and Figure 5 The waterway plate 100 further includes an exhaust pipe 80, which is used to communicate with the hot water tank 201 to discharge the steam in the hot water tank 201. Since the heat exchange medium (hot water) in the hot water tank 201 will generate steam, when the steam reaches a certain level, the air pressure in the hot water tank 201 increases, which is potentially dangerous. By setting the exhaust pipe 80 to discharge the steam in the hot water tank 201, the safety of the hot water tank 201 is improved.

[0065] In this embodiment, the water supply pipeline 10, the water inlet pipeline 20, the water outlet pipeline 30, the bridge pipeline 40, the heat exchange medium output pipeline 60, the heat exchange medium return pipeline 70 and the exhaust pipeline 80 are integrated, which greatly improves the integration of the waterway plate 100 and is conducive to the miniaturized design of the water supply device.

[0066] In one embodiment, the pipelines of the waterway plate 100 are integrally formed, so as to improve the connection sealing performance between the pipelines and prevent water leakage of the pipelines.

[0067] See also Figure 5 The embodiment of the present invention also provides a water supply device, including a water demanding device 200 and the above-mentioned waterway plate 100, wherein the water supply pipeline 10 of the waterway plate 100 is connected to the water demanding device 200 to supply water to the water demanding device 200. By adopting the above-mentioned waterway plate 100, on the basis of being able to provide normal temperature water to the water demanding device 200, the integration of each pipeline is improved, the space occupied by the pipeline is reduced, and the miniaturization design of the water supply device is facilitated.

[0068] See also Figure 2 and Figure 5 The water supply device also includes a water treatment device 300, which is used to allow heat exchange medium and drinking water to flow through simultaneously and in isolation, and to allow the heat exchange medium and drinking water in the water treatment device 300 to exchange heat; the water demand device 200 includes a hot water tank 201, in which a heat exchange medium is arranged, and the hot water tank 201 is connected to the water treatment device 300, so that the heat exchange medium can flow into the water treatment device 300 for heat exchange and then flow back to the hot water tank 201. The heat exchange medium is water. The water supply pipeline 10 is connected to the hot water tank 201 to replenish water flow to the hot water tank 201.

[0069] See also Figure 6 The water treatment device 300 is provided with a drinking water channel (not marked in the figure), a drinking water input port 301, a drinking water output port 302, a medium channel (not marked in the figure), a medium input port 303 and a medium output port 304. The drinking water channel and the medium channel are adjacent and isolated. The drinking water input port 301 and the drinking water output port 302 are respectively connected to the drinking water channel, and the medium input port 303 and the medium output port 304 are respectively connected to the medium channel. The drinking water channel is used for drinking water to flow through, and the medium 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 water treatment device 300 at the same time, heat exchange is performed between the two, so that the normal temperature drinking water generates hot drinking water.

[0070] See also Figure 1 , Figure 6 and Figure 7 The hot water tank 201 is provided with a medium discharge port 2011 and a medium return port 2012. The medium discharge port 2011 and the medium input port 303 of the water treatment device 300 are connected through the heat exchange medium output pipeline 60 of the water circuit plate 100. The medium return port 2012 and the medium output port 304 of the water treatment device 300 are connected through the heat exchange medium return pipeline 70 of the water circuit plate 100, thereby realizing the medium channel connection between the hot water tank 201 and the water treatment device 300.

[0071] like Figure 3 , Figure 4 and Figure 7 As shown, the hot water tank 201 is also provided with a water replenishment port 2013 and an exhaust port 2014. The water replenishment pipeline 10 is connected to the water replenishment port 2013 to replenish water for the hot water tank 201. The exhaust pipeline 80 is connected to the exhaust port 2014 so that the steam in the hot water tank 201 enters the exhaust pipeline 80 through the exhaust port 2014.

[0072] See also Figure 5 and Figure 6The water supply device also includes a heater 400, which is arranged downstream of the water treatment device 300 and is used to heat the drinking water from the water treatment device 300. Specifically, the water inlet end of the heater 400 is connected to the drinking water outlet 302 of the water treatment device 300, and the water outlet end of the heater 400 is connected to the water outlet pipeline 30. By arranging the water treatment device 300 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 water output is "fresh" hot water. Of course, in other embodiments, the water supply device may not be provided with a heater 400.

[0073] In one embodiment, the water demanding device 200 further includes an ice bladder (not shown), which is used to cool the water flowing through the ice bladder to generate cold water. In specific applications, the ice bladder can be connected to the water using end to deliver cold water to the water using end.

[0074] When the water circuit board 100 is used to provide hot water to the water-using end, the second control valve 52 and the fourth control valve 54 are controlled to be open, and the first control valve 51 and the third control valve 53 are closed, and normal temperature water flows into the water inlet pipe 20, and then flows to the water treatment device 300 and the heater 400 through the water inlet pipe 20. After hot water is generated, it flows to the water-using end through the water outlet pipe 30.

[0075] When the water circuit plate 100 is used to provide hot water for the water-demanding device 200, the third control valve 53 and the fourth control valve 54 are controlled to be open, and the first control valve 51 and the second control valve 52 are closed, and normal temperature water flows into the water inlet pipe 20, and then flows to the water treatment device 300 and the heater 400 through the water inlet pipe 20. After hot water is generated, it flows into the water outlet pipe 30, and flows into the second branch 12 through the water outlet pipe 30 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 into the first branch 11 to replenish water for the hot water tank 201.

[0076] When the water circuit plate 100 is used to provide normal temperature water to the water-using end, the first control valve 51 and the second control valve 52 are controlled to be open, and the third control valve 53 and the fourth control valve 54 are controlled to be closed, and the normal temperature water flows into the water inlet pipe 20, flows into the water outlet pipe 30 through the bridge pipe 40, and then flows to the water-using end through the water outlet pipe 30.

[0077] When the water circuit plate 100 is used to provide normal temperature water for the water-demanding device 200, the first control valve 51 and the third control valve 53 are controlled to be open, and the second control valve 52 and the fourth control valve 54 are closed. Normal temperature water flows into the water inlet pipe 20, flows into the water outlet pipe 30 through the bridge pipe 40, and then flows into the second branch 12 through the water outlet pipe 30 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 into the first branch 11 to replenish water for the hot water tank 201.
