[0038] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0041] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0042] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0043] It should be noted that in this embodiment, the first direction X refers to the length direction of the water channel plate, the second direction Y refers to the width direction of the water channel plate, and the third direction Z refers to the height direction of the water channel plate. The dashed lines in the attached figure indicate the flow direction of water in the pipeline.

[0044] like Figures 1 to 6 As shown, the water circuit board 100 provided in this embodiment of the present invention includes a first pipe 10, a second pipe 20, a first valve body 61, and a second valve body 62. The first pipe 10 extends along a first direction X and is used to connect to the water-using end. The second pipe 20 extends at least partially along a second direction Y and crosses the first pipe 10, and is used to connect the first pipe 10 and the water-requiring device 200. The first valve body 61 is used to control the on / off state of the first pipe 10, and the second valve body 62 is used to control the on / off state of the second pipe 20. The first valve body 61 and the second valve body 62 are both connected to the first pipe 10 and are arranged adjacent to each other along the first direction X.

[0045] In specific implementation, when the first valve body 61 is opened and the second valve body 62 is closed, the first pipeline 10 is connected to the water-using end, and the first pipeline 10 and the second pipeline 20 are disconnected. The first pipeline 10 can supply water to the water-using end, thus achieving water supply to the water-using end. When the second valve body 62 is opened and the first valve body 61 is closed, the first pipeline 10 and the second pipeline 20 are connected, and the first pipeline 10 is disconnected from the water-using end. The first pipeline 10 can supply water to the second pipeline 20, thereby supplying water to the water-demanding device 200, thus achieving water supply to the water-demanding device 200.

[0046] By adopting the above technical solution, the first pipeline 10 is opened and closed by setting the first valve body 61. The second pipeline 20 is opened and closed by setting the second valve body 62. By arranging the first valve body 61 and the second valve body 62 adjacent to each other along the first direction X in the first pipeline 10, the first valve body 61 and the second valve body 62 can be compactly connected to the first pipeline 10. Compared with the technical solution where the first valve body 61 is connected to the first pipeline 10 and the second valve body 62 is connected to the second pipeline 20, the compactness of the arrangement of the first valve body 61 and the second valve body 62 is improved. Therefore, the water circuit board 100 provided in this embodiment improves the compactness of the valve body arrangement, which is beneficial to reducing the space occupied by the water circuit board 100.

[0047] The water channel plate 100 has a first end 100a and a second end 100b disposed opposite to each other along the second direction Y. A first valve body 61 extends from the first pipe 10 along the second direction Y with a tendency to approach the first end 100a, and a second valve body 62 extends from the first pipe 10 along the second direction Y with a tendency to approach the second end 100b. That is, both the first valve body 61 and the second valve body 62 extend along the second direction Y and are respectively disposed on both sides of the first pipe 10. It can be understood that in other embodiments, the first valve body 61 and the second valve body 62 may also be disposed on the same side of the first pipe 10.

[0048] In one embodiment, the inlet end of the first valve body 61 and the inlet end of the second valve body 62 are arranged adjacent to each other. By setting the first valve body 61 and the second valve body 62 on both sides of the first pipeline 10, and arranging the inlet ends of the first valve body 61 and the second valve body 62 adjacent to each other, the first valve body 61 and the second valve body 62 are valve bodies with the same flow direction. Therefore, when installing the valve bodies, valve bodies of the same specification can be used, and there is no need to worry about whether the valve bodies are installed backwards, which greatly improves the installation efficiency of the valve bodies.

[0049] Please see Figure 1 and Figure 4The water circuit board 100 has two first connecting parts 71 and two second connecting parts 72, both of which are connected to the first pipeline 10. The two first connecting parts 71 are located downstream of and adjacent to the two second connecting parts 72. A first valve body 61 is installed on the two first connecting parts 71, and a second valve body 62 is installed on the two second connecting parts 72. This arrangement ensures that the first valve body 61 and the second valve body 62 are arranged adjacent to each other along the first direction X in the first pipeline 10. By placing the two first connecting parts 71 downstream of the two second connecting parts 72, the first valve body 61 is located downstream of the second valve body 62. Thus, when the first valve body 61 controls the opening and closing of the first pipeline 10, it controls the connection between the first pipeline 10 and the water-using end, without affecting the connection between the first pipeline 10 and the second pipeline 20. In specific applications, both the two first connecting parts 71 and the two second connecting parts 72 extend along the third direction Z.

[0050] In one embodiment, two first connecting portions 71 are arranged along a first direction X, one first connecting portion 71 is connected to the water inlet end of the first valve body 61, and the other first connecting portion 71 is connected to the water outlet end of the first valve body 61. In this way, the first valve body 61 can extend along a second direction Y.

[0051] In one embodiment, two second connecting parts 72 are arranged along a first direction X, and the second pipe 20 and the first pipe 10 are arranged along a third direction Z. One second connecting part 72 is connected to the water inlet end of the second valve body 62, and the other second connecting part 72 is connected to the water outlet end of the second valve body 62, extending across the first pipe 10 along the third direction Z to the second pipe 20. This allows the second valve body 62 to extend along a second direction Y, with its water outlet end connected to the second pipe 20. By controlling the opening or closing of the second valve body 62, the on / off state of the second pipe 20 can be controlled. The second pipe 20 and the second connecting part 72 are respectively located on both sides of the first pipe 10 along the third direction Z. Specifically, the second pipe 20 is located below the first pipe 10, and the second connecting part 72 is located above the first pipe 10, thus allowing the second valve body 62 to be positioned above the water circuit board 100. In addition, the first connecting part 71 adjacent to the second connecting part 72 is connected to the water inlet end of the first valve body 61, and the second connecting part 72 adjacent to the first connecting part 71 is connected to the water inlet end of the second valve body 62, so that the water inlet end of the first valve body 61 and the water inlet end of the second valve body 62 are arranged adjacent to each other.

[0052] Please see Figure 2 and Figure 3The water circuit board 100 also includes a third pipe 30 and a fourth pipe 40. The third pipe 30 extends along a first direction X and is arranged adjacent to the first pipe 10 along a second direction Y, for connecting to a water source. The fourth pipe 40 extends along either the second direction Y or a third direction Z, connecting the first pipe 10 and the third pipe 30, so that water in the third pipe 30 can flow into the first pipe 10. This allows water to be supplied to the first pipe 10. By providing the third pipe 30 and the fourth pipe 40 in the water circuit board 100, the integration of the water circuit board 100 can be improved, and arranging the third pipe 30 adjacent to the first pipe 10 along the second direction Y allows for a compact arrangement of the first pipe 10 and the third pipe 30.

[0053] Please see Figure 2 and Figure 3 The water circuit board 100 also includes a third valve body 63, which is used to control the opening and closing of the fourth pipeline 40. In specific applications, when it is necessary to supply water to the first pipeline 10, the third valve body 63 can be opened to allow the fourth pipeline 40 to be open, and the water can flow through the fourth pipeline 40 from the third pipeline 30 into the first pipeline 10.

[0054] In one embodiment, the portion of the first pipe 10 that connects to the fourth pipe 40 is located upstream of the portion of the first pipe 10 that connects to the second pipe 20. Thus, water from the third pipe 30 can flow through the fourth pipe 40 and the first pipe 10 to be transported to the second pipe 20.

[0055] In one embodiment, the first valve body 61 is located on the side of the first pipe 10 closer to the third pipe 30, and the second valve body 62 is located on the side of the first pipe 10 away from the third pipe 30. That is, the third pipe 30 is located on the side of the first pipe 10 closer to the first end 100a. At least a portion of the third valve body 63 is located between the first pipe 10 and the third pipe 30. The third valve body 63 extends along the first direction X with a tendency to approach the first valve body 61 and is correspondingly arranged with the second valve body 62. In this way, the third valve body 63 can be accommodated in the space on the side of the second valve body 62 facing the first end 100a, and is compactly arranged with the first valve body 61 and the second valve body 62, which greatly improves the compactness of the arrangement of the first valve body 61, the second valve body 62 and the third valve body 63. Furthermore, making the flow direction of the third valve body 63 the same as the flow direction of the first valve body 61 and the second valve body 62 can speed up the assembly efficiency of the valve body.

[0056] Please see Figure 2 and Figure 4The water circuit board 100 also has two third connecting parts 73, which are arranged along the second direction Y. One third connecting part 73 connects between the third pipe 30 and the inlet end of the third valve body 63, and the other third connecting part 73 connects between the fourth pipe 40 and the outlet end of the third valve body 63. In this way, the third valve body 63 is installed and extends along the first direction X. Specifically, the third connecting part 73 extends along the third direction Z.

[0057] In one embodiment, the third pipe 30 is also used to connect to the water treatment device 300. In this way, the third pipe 30 can also supply water to the water treatment device 300.

[0058] Please see Figure 2 and Figure 6 The water circuit board 100 also includes a fourth valve body 64, which is used to control the connection and disconnection between the third pipeline 30 and the water treatment device 300. In specific applications, when it is necessary to supply water to the water treatment device 300, the fourth valve body 64 can be opened, thereby connecting the third pipeline 30 and the water treatment device 300, and the water in the third pipeline 30 can flow into the water treatment device 300.

[0059] In one embodiment, the portion of the third pipe 30 that connects to the fourth pipe 40 is located upstream of the portion of the third pipe 30 that connects to the water treatment device 300. At least a portion of the fourth valve body 64 is connected to the third pipe 30. The fourth valve body 64 extends along the second direction Y with a tendency to approach the first pipe 10, and is adjacent to and correspondingly arranged with the third valve body 63. That is, the fourth valve body 64 and the first valve body 61 are respectively arranged on opposite sides of the third valve body 63 along the first direction X. This arrangement increases the compactness of the arrangement of the fourth valve body 64 with the first valve body 61, the second valve body 62, and the third valve body 63. Furthermore, the flow direction of the fourth valve body 64 is the same as the flow direction of the first valve body 61, the second valve body 62, and the third valve body 63, which can speed up the assembly efficiency of the valve body.

[0060] Please see Figure 3 , Figure 4 and Figure 6The water circuit board 100 also includes a fifth pipe 50, which extends along the second direction Y and is located at the end of the third pipe 30. The fifth pipe 50 connects the third pipe 30 and the water treatment device 300. The water circuit board 100 also includes two fourth connecting parts 74, arranged along the first direction X. One fourth connecting part 74 connects the third pipe 30 to the inlet end of the fourth valve body 64, and the other fourth connecting part 74 connects the outlet end of the fourth valve body 64 to the fifth pipe 50. This arrangement allows the fourth valve body 64 to extend along the second direction Y and enables it to control the opening and closing of the fifth pipe 50, thereby controlling the connection and closing of the third pipe 30 and the water treatment device 300. The fourth connecting parts 74 extend along the third direction Z.

[0061] It is understood that in other embodiments, the water circuit board 100 may not be provided with the fifth pipe 50. When this technical solution is adopted, both fourth connection parts 74 are connected to the third pipe 30 and arranged along the first direction X. One fourth connection part 74 is connected to the water inlet end of the fourth valve body 64, and the other fourth connection part 74 is connected to the water outlet end of the fourth valve body 64.

[0062] In one embodiment, the first connecting part 71, the second connecting part 72, the third connecting part 73 and the fourth connecting part 74 are all located above the water circuit board 100. This allows the first valve body 61, the second valve body 62, the third valve body 63 and the fourth valve body 64 to be arranged above the water circuit board 100. The valve bodies will not affect the arrangement of the water circuit board 100 and other components of the water supply device (such as the hot water tank 201), which facilitates the installation of the water circuit board 100.

[0063] In one embodiment, the first pipe 10 is also used to connect to the water treatment device 300. Thus, the first pipe 10 also receives water from the water treatment device 300. In specific applications, the water supplied by the water treatment device 300 to the first pipe 10 is heated water (hot water), while the water supplied by the third pipe 30 to the first pipe 10 is unheated water (room temperature water).

[0064] In one embodiment, the portion of the first pipe 10 that connects to the water treatment device 300 is located upstream of the portion of the first pipe 10 that connects to the fourth pipe 40. This allows the heated water to flow through the entire first pipe 10, enabling high-temperature disinfection of the first pipe 10.

[0065] Please see Figure 5 and Figure 6The water circuit board 100 has a third end 100c and a fourth end 100d arranged opposite to each other along the first direction X. The part of the first pipe 10 that connects to the water supply end and the part of the third pipe 30 that connects to the water source are both located near the third end 100c. The part of the first pipe 10 that connects to the water treatment device 300 and the part of the third pipe 30 that connects to the water treatment device 300 are both located near the fourth end 100d.

[0066] When the water circuit board 100 is used to provide hot water to the water user, the first valve body 61 and the fourth valve body 64 are opened, and the second valve body 62 and the third valve body 63 are closed. The room temperature water flows through the third pipe 30 and the fifth pipe 50 and enters the water treatment device 300. After being treated by the water treatment device 300 to generate hot water, it flows into the first pipe 10 and is then delivered to the water user.

[0067] When the water circuit board 100 provides hot water to the water-requiring device 200, the second valve body 62 and the fourth valve body 64 are opened, and the first valve body 61 and the third valve body 63 are closed. The room temperature water flows through the third pipe 30 and the fifth pipe 50 and enters the water treatment device 300. After being treated by the water treatment device 300 to generate hot water, it flows into the first pipe 10, and then flows through the second pipe 20 to be delivered to the water-requiring device 200.

[0068] When the water circuit board 100 is used to supply room temperature water to the water user, the first valve body 61 and the third valve body 63 are opened, and the second valve body 62 and the fourth valve body 64 are closed. The room temperature water flows through the third pipe 30 and the fourth pipe 40, enters the first pipe 10, and is then delivered to the water user.

[0069] When the water circuit board 100 provides room temperature water to the water demand equipment 200, the second valve body 62 and the third valve body 63 are opened, and the first valve body 61 and the fourth valve body 64 are closed. The room temperature water flows through the third pipeline 30 and the fourth pipeline 40, enters the first pipeline 10, and then flows through the second pipeline 20 to be delivered to the water demand equipment 200.

[0070] Please see Figure 3 and Figure 6 This utility model embodiment also provides a water supply device, including a water circuit board 100 and a water demand device 200, with a second pipeline 20 connected to the water demand device 200 to replenish water to the water demand device 200.

[0071] The water-requiring component can be a hot water tank 201 and / or a cold water tank. The hot water tank 201 stores a heat exchange medium for heat exchange with drinking water, and the cold water tank is used to cool the flowing water to produce cold drinking water. The heat exchange medium is water. It is understood that in other embodiments, when the water-requiring component does not include a hot water tank 201, the heat exchange medium can also be heat transfer oil.

[0072] In one embodiment, the water supply device further includes a water treatment device 300, which includes a heat exchanger 301. The heat exchanger 301 has an adjacent but isolated first flow channel (not shown) and a second flow channel (not shown). The first flow channel is connected to the hot water tank 201, and the second flow channel is connected to the first pipe 10 and the third pipe 30 of the water circuit board 100. Specifically, the heat exchange medium in the hot water tank 201 can flow from the hot water tank 201 into the first flow channel, exchange heat with the water in the second flow channel, and then flow back into the hot water tank 201. The water in the third pipe 30 flows into the second flow channel, exchanges heat with the heat exchange medium in the first flow channel to generate hot water, and then flows into the first pipe 10.

[0073] In one embodiment, the water treatment device 300 further includes a heater 302, which is located downstream of the heat exchanger 301 and is used to heat the water from the heat exchanger 301. Specifically, the heater 302 connects the heat exchanger 301 and the first pipe 10 of the water circuit board 100. By using the heat exchanger 301 and the heater 302 to heat the drinking water, the heating effect of the drinking water can be improved, enabling a large flow of hot drinking water to be produced. The hot drinking water does not need to be preheated and stored, meaning the output water is always "fresh" hot water. Of course, in other embodiments, the water treatment device 300 may not include the heater 302.

[0074] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
