Description

Technical Field

[0001] This utility model relates to the field of drinking water treatment, and in particular to a water circuit board and water supply device. Background Technology

[0002] Water supply devices can quickly and conveniently provide users with fresh, safe, and hygienic drinking water, including hot, cold, and room-temperature water, and are becoming increasingly popular. Currently, one type of water supply device uses heat exchange heating, direct heating, or a combination of both. In the heat exchange heating method, a heat exchange tank stores the hot water solution, which exchanges heat with the drinking water flowing through the heat exchange device, thereby heating the drinking water.

[0003] The hot water exchange fluid in the heat exchange tank generates steam due to its high temperature before heat exchange. If this steam is not discharged in time, it will cause the pressure in the heat exchange tank to increase, leading to safety issues. Additionally, the hot water source cools down after heat exchange and flows back into the heat exchange tank for reheating, resulting in circulating heating. This can cause scale buildup and other problems in the heat exchange tank. Therefore, it is necessary to drain the hot water exchange fluid from the heat exchange tank periodically or irregularly. Currently, venting and draining the hot water exchange fluid are separate processes. Users need to connect two external pipes, one for venting and the other for draining. This results in multiple external pipes, increasing operating costs and hindering sales and promotion. Utility Model Content

[0033] An existing water supply system uses a heat exchanger tank to provide a heat exchange medium (hot water) that exchanges heat with drinking water from a water source inside the heat exchanger to heat the drinking water before supplying it to the user. After heat exchange, the heat exchange medium cools down and flows back to the heat exchanger tank. This heat exchange method, using a heat exchanger tank to heat and store room-temperature water as the heat exchange medium, has two main drawbacks. First, the heat exchange medium, before and after heating, will generate water vapor due to its high temperature. This water vapor needs to be discharged promptly; otherwise, it will accumulate, increasing the pressure inside the heat exchanger tank and posing a safety hazard. Second, after heat exchange, the water cools down to room temperature and flows back to the heat exchanger tank, where it is reheated as the heat exchange medium. This cyclic heating process can lead to scale buildup in the heat exchanger tank, requiring periodic or periodic drainage and replacement with fresh room-temperature water. Therefore, the existing water supply system includes pipes for removing water vapor and pipes for removing the heat exchange medium from the heat exchanger tank. The user also needs two corresponding pipes: one for removing water vapor and one for removing the heat exchange medium (cooled down to room temperature water). This would increase the number of water-using pipes and make the wiring more complicated. Moreover, since two pipes are needed, one for venting and the other for drainage, the cost would be higher, which would be detrimental to the sales and promotion of the water supply device.

[0034] In view of this, the present invention provides a water circuit board and a water supply device. The water supply device includes a water circuit board, with a main pipe of a first pipeline and a second pipeline arranged along the length of the water circuit board and connected in parallel along the width of the water circuit board. A branch pipe of the first pipeline is arranged along the thickness of the water circuit board, and a third pipeline is also arranged along the thickness of the water circuit board and intersects with the second pipeline. Firstly, water vapor and heat exchange medium discharge share a single pipeline, reducing the number of pipelines used for connection at the water end and lowering user costs. Secondly, it fully utilizes the space of the water circuit board in the width and thickness directions, improving the integration of the water circuit board and reducing its space occupation, which is conducive to the integration and miniaturization of the water supply device.

[0035] like Figure 1 , Figure 2 , Figure 3As shown in the figure, a water circuit board 100 provided in this embodiment of the present invention includes a first pipe 11, a second pipe 12, a third pipe 13, and a drive assembly 40. The first pipe 11 includes a main pipe 111 arranged along a first direction and a branch pipe 112 arranged along a second direction. The branch pipe 112 has a first inlet 1121 at its end away from the main pipe 111. The second pipe 12 is arranged along the first direction, adjacent to and connected to the main pipe 111 along a third direction, and includes a first outlet 121. The third pipe 13 is arranged along the second direction and intersects with the second pipe 12. The drive assembly 40 is connected to both the second pipe 12 and the third pipe 13, and is used to control and drive the water flow to the second pipe 12 and discharge from the first outlet 121. Wherein, the first direction is the length direction XX of the water channel plate 100, the second direction is the thickness direction ZZ of the water channel plate 100, and the third direction is the width direction YY of the water channel plate 100.

[0036] Understandably, the first outlet 121 of the second pipe 12 is used to connect to the pipe at the water-using end (not shown) to discharge water vapor and liquid. Water vapor enters through the first inlet 1121, flows to the first outlet 121, and then automatically discharges into the pipe at the water-using end. When the drive assembly is working, it drives liquid into the second pipe 12 and discharges it from the first outlet 121. Thus, by connecting only one pipe at the water-using end, water vapor and wastewater (the liquid that the water supply device needs to discharge) can be discharged through the water circuit board 100, reducing the number of pipes required at the water-using end from two to one, reducing operating costs, facilitating sales and promotion, and utilizing the wiring at the water-using end.

[0037] In one embodiment, a first connecting pipe 18 is further included, which is disposed along the third direction, and the main pipe 111 is connected to the second pipe 12 through the first connecting pipe 18.

[0038] Further reading Figure 1 , Figure 5The water circuit board 100 is used for the water supply device 1000, which includes a heat tank 200. The first inlet 1121 of the branch pipe body 112 of the first pipeline 11 is connected to the water vapor outlet (not shown) of the heat tank 200. The main pipe body 111 of the first pipeline 11 is connected to the second pipeline 12 through the first connecting pipe 18. When the pressure of the water vapor accumulated in the heat tank 200 is greater than the external atmospheric pressure, the water vapor is automatically discharged from the water vapor outlet, enters the branch pipe body 112 through the first inlet 1121, and then passes through the main pipe body 111 and the first connecting pipe 18, before being discharged into the water-using pipeline through the first outlet 121 of the second pipeline 12. The second pipeline 12 has a second inlet (not shown) at one end opposite to the first outlet 121. The third pipeline 13 has a third inlet 133 at one end away from the second pipeline 12, which is used to connect to the liquid outlet (not shown) of the heat tank 200. When the drive assembly 40 is working, under its control and drive, the water in the hot tank 200 flows from the water outlet into the third inlet 133 of the third pipe 13, then through the third pipe 13, into the second pipe 12, and finally flows to the first outlet 121 and is discharged into the water-using end pipe. A first connecting pipe 18 connects the main body 111 of the first pipe 11 to the second pipe 12. As described above, the water-using end does not require a second pipe to connect to the first pipe 11; it can share the pipe connected to the second pipe 12 to discharge water vapor, reducing the number of pipes, saving costs, and facilitating installation and wiring. Furthermore, the main pipe 111 of the first pipe 11 and the second pipe 12 are both arranged along the length direction XX and adjacent along the width direction YY. Therefore, the first connecting pipe 18, which is also arranged along the width direction YY, is the shortest path connecting the main pipe 111 and the second pipe 12, which helps to shorten the water vapor flow time and thus accelerate the discharge of water vapor.

[0039] Please refer to it again. Figure 1 In one embodiment, the first connecting pipe 18 is disposed close to the first outlet 121 along the first direction. Specifically, by disposing the first connecting pipe 18 close to the first outlet 121, water vapor from the first pipe 11 only needs to pass through a small section of the second pipe 12 after passing through the first connecting pipe 18 to reach the first outlet 121. This allows for full utilization of the width YY dimension of the water channel plate 100, reducing the size of the water channel plate 100; it also facilitates faster water vapor discharge.

[0040] Please see Figure 3 and Figure 4 In one embodiment, the drive assembly 40 includes a three-way valve 401, one input end 4011 of which is connected to the other end of the third pipeline 13. The three-way valve 401 can be an electromagnetic three-way valve, an electric three-way valve, etc., and is not limited here. Specifically, the other end of the third pipeline 13, i.e., the end opposite to the third inlet 133, has a third outlet (not shown). The water circuit board 100 also has a first connecting seat 51 for mounting the input end 4011 of the three-way valve 401, and the first connecting seat 51 communicates with the third outlet. When the input end 4011 of the three-way valve 401 is installed in the first connecting seat 51, the three-way valve 401 can control the connection or disconnection between the third outlet and the input end 4011.

[0041] Furthermore, the drive assembly 40 also includes a pump body 402 disposed along the first direction 101. The input end (not shown) of the pump body 402 is connected to the output end 4010 of the three-way valve 401, and the output end (not shown) of the pump body 402 is connected to the second inlet (not shown) of the second pipeline 12. The pump body 402 can be a plunger pump, gear pump, fixed displacement pump, variable displacement pump, etc., and is not limited here. Specifically, the water circuit board 100 is also provided with a second connecting seat 52 for mounting the output end 4010 of the three-way valve 401. The second connecting seat 52 is connected to the input end of the pump body 402. The second inlet is connected to the output end of the pump body 402. When the output end 4010 of the three-way valve 401 is installed on the second connecting seat 52, the three-way valve 401 can control the connection or disconnection between the output end 4010 and the input end of the pump body 402. When the three-way valve 401 controls the output end 4010 to connect with the input end of the pump body 402, the pump body 402 operates, driving the water to flow from the third pipeline 13 to the second pipeline 12 and discharge through the outlet 121.

[0042] In one embodiment, the water circuit board 100 further includes a fourth pipe 14, which is arranged along the first direction 101 and adjacent to the second pipe 12 along a third direction 103. One end is used to connect to the water-using end, and the other end is connected to the other input end 4012 of the three-way valve 401. Specifically, the fourth pipe 14 includes a fourth inlet 144, and a fourth outlet (not shown) is provided at the end opposite to the fourth inlet 144. The fourth inlet 144 is used to connect to the water-using end. The water circuit board 100 is also provided with a third connecting seat 53 for installing the other input end 4012, and the third connecting seat 53 communicates with the fourth outlet of the fourth pipe 14. When the other input end 4012 is installed in the third connecting seat 53, the three-way valve 401 can control the connection or disconnection between the fourth outlet and the other input end 4012.

[0043] Understandably, the water supply device 1000 includes multiple water supply modes, such as hot water mode, normal temperature mode, and cold water mode. When switching from one water supply mode to another, such as from hot water mode to cold water mode, the pipes at the water end will retain hot water from the previous mode. This remaining hot water needs to be released before cold water can be dispensed. If released directly at the water end, it will cause the hot and cold water to mix, meaning that the dispensed water is not the "required water," which will greatly affect the user experience. Therefore, when switching water supply modes, the remaining water from the previous mode needs to be automatically discharged to the municipal water supply pipeline through other pipes.

[0044] Specifically, when switching from one water supply mode to another, the pump body 402 and the three-way valve 401 will operate, controlling and driving the remaining water at the water-using end to quickly flow from the water-using end through the fourth pipe 14, the other input end 4012 of the three-way valve 401, the output end 4010 of the three-way valve 401, and the pump body 402, and then be discharged through the second pipe 12. The fourth pipe 14 and the second pipe 12 are both arranged along the length direction of the water circuit plate 100 and are adjacent along the width direction of the water circuit plate 100, with their ends flush. The pump body 402 is located along the length direction of the water circuit plate 100 near the other end of the second pipe 12 (the end opposite to the first outlet 121). The structure is compact, and the flow path of the remaining water from the water-using end is short, so it can quickly flow from the water-using end through the second pipe 12, the three-way valve 401, the pump body 402, and then be discharged through the second pipe 12 to the external pipe. This allows for the rapid release of any remaining water from the previous water supply mode when switching modes, and then the desired water supply mode is switched. This process is so quick that users may not even notice the delay, greatly improving the user experience.

[0045] Furthermore, the water circuit board 100 also includes a fifth pipe 15, which is arranged along the first direction and adjacent to the fourth pipe 14 along a third direction. Specifically, the fifth pipe 15 is used to connect to the water-using end and to transport the drinking water treated (heated or cooled) by the supply device to the water-using end.

[0046] Furthermore, the water circuit board 100 also includes a sixth pipe 16, which is arranged along the first direction and adjacent to the fifth pipe 15 along a third direction. Specifically, the sixth pipe 16 is used to connect the water source and the fifth pipe 15, and is used to input drinking water into the drinking water processed by the supply device or directly transport room temperature water to the second pipe 12, and then transport it to the water-using end via the fifth pipe 15.

[0047] Furthermore, the water circuit board 100 also includes a seventh pipe 17, which includes a first branch 171 arranged along a first direction, a second branch 172 arranged along a second direction, and a third branch 173 arranged along a third direction. The two ends of the third branch 173 are respectively connected to the first branch 171 and the second branch 172. Specifically, the third branch 173 of the seventh pipe 17 is connected to or disconnected from the fifth pipe 15 through a control valve (not shown). The first branch 171 and the second branch 172 are respectively used to connect the ice tank and the hot water tank 200 of the water supply device 1000, and respectively replenish water to the ice tank and the hot water tank 200.

[0048] Understandably, when the process involves heating room temperature water using heat exchange to supply hot water, cooling room temperature water using the ice tank, and storing cold water, it is necessary to replenish water to the hot water tank 200 and the ice tank. Replenishing water to the hot water tank 200 is necessary because, as mentioned above, the heat exchange medium in the hot water tank 200 will evaporate due to the high temperature, and it also needs to be replaced or replenished periodically. Replenishing water to the ice tank is mainly due to usage consumption. When water needs to be replenished to the ice tank and / or the ice tank, drinking water from the water source is transported through the fifth pipeline 15 to the third branch 173, and then replenished to the ice tank and the hot water tank 200 via the first branch 171 and the second branch 172, respectively.

[0049] This utility model embodiment also provides a water supply device 1000, which includes the water circuit board 100 described above.

[0050] 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.
