[0032] 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.

In the accompanying drawings, the dashed lines represent the flow direction of water in the pipeline.
[0036] To better meet people's needs, current water supply systems are equipped with hot water generating devices. However, in related technologies, the internal piping design of hot water generating devices is unreasonable, which not only makes the assembly efficiency of hot water generating devices low, but also makes the hot water generating devices occupy a large space.
[0037] In view of this, the present invention provides a water supply device to improve the assembly efficiency of the hot water generating device and reduce the space occupied by the hot water production device.
[0038] like Figure 1 and Figure 2 As shown in the figure, the water supply device 100 provided in this embodiment of the present invention includes a heat storage device 10 and a heat exchange device 20. The heat storage device 10 is used to store a heat exchange medium, and the heat exchange device 20 is used to supply heat exchange medium and drinking water simultaneously and in isolation, allowing the heat exchange medium and drinking water located in the heat exchange device 20 to exchange heat. The heat storage device 10 and the heat exchange device 20 are connected so that the heat exchange medium can flow into the heat exchange device 20 for heat exchange and then flow back to the heat storage device 10. The heat exchange medium can be water, heat transfer oil, or other media capable of heat exchange.
[0039] By setting up a heat storage device 10 and a heat exchange device 20, the heat exchange medium in the heat storage device 10 exchanges heat with drinking water in the heat exchange device 20, so that the drinking water is converted into drinking hot water, thereby enabling the water supply device 100 to provide hot water.
[0040] Please see Figures 1 to 3 The water supply device 100 also includes a water circuit board 30, which includes a medium output pipe 31 and a medium return pipe 32. The medium output pipe 31 connects the heat storage device 10 and the heat exchange device 20, and is used to transport the heat exchange medium in the heat storage device 10 to the heat exchange device 20. The medium return pipe 32 connects the heat exchange device 20 and the heat storage device 10, and is used to return the heat exchange medium flowing through the heat exchange device 20 to the heat storage device 10.
[0041] By setting up a medium output pipe 31 and a medium return pipe 32, the heat storage device 10 and the heat exchange device 20 are connected. Integrating the medium output pipe 31 and the medium return pipe 32 into the water circuit board 30 facilitates the rational arrangement of the medium output pipe 31 and the medium return pipe 32, and facilitates the assembly of the heat storage device 10, the heat exchange device 20, the medium output pipe 31, and the medium return pipe 32. Furthermore, it improves the integration of the medium output pipe 31 and the medium return pipe 32, reduces their space occupation, and is conducive to the miniaturization of the water supply device 100.
[0042] Please see Figure 2 and Figure 3 The water circuit board 30 also includes a water pump 331, which is connected to the medium output pipeline 31 to provide power for the flow of the heat exchange medium within the medium output pipeline 31. In specific applications, the water pump 331 can be started when it is necessary to output the heat exchange medium, so that the heat exchange medium can flow between the heat storage device 10 and the heat exchange device 20, thereby exchanging heat with the drinking water in the heat exchange device 20 as it flows through it. It is understood that in other embodiments, the water pump 331 may also be connected to the heat exchange medium return pipeline 32.
[0043] Please see Figures 1 to 3 The water circuit board 30 also includes a water supply pipe 34 and a water outlet pipe 35. One end of the water supply pipe 34 is connected to a water source, and the other end is connected to the heat exchange device 20. The water supply pipe 34 is used to supply drinking water to the heat exchange device 20. One end of the water outlet pipe 35 is connected to a water outlet (such as a faucet), and the other end is connected to the heat exchange device 20. The water outlet pipe 35 is used to receive drinking water from the heat exchange device 20. Integrating the water supply pipe 34 and the water outlet pipe 35 into the water circuit board 30 improves the integration of the water circuit board 30 and helps to reduce the space occupied by the water supply device 100.
[0044] In one embodiment, the water source can be purified water filtered through a reverse osmosis membrane.
[0045] Please see Figures 2 to 4 The heat exchanger 20 is provided with a medium inlet 21, a medium outlet 22, and a medium channel (not shown in the figure) connecting the medium inlet 21 and the medium outlet 22. The liquid outlet end of the medium outlet pipe 31 is connected to the medium inlet 21, and the liquid inlet end of the medium return pipe 32 is connected to the medium outlet 22. In specific applications, the heat exchange medium in the heat storage device 10 flows into the medium channel through the medium inlet 21, exchanges heat with the drinking water located in the heat exchanger 20, and then flows back into the heat storage device 10 through the medium outlet 22.
[0046] Please see Figures 3 to 5The heat storage device 10 is provided with a medium outlet 11 and a medium return port 12. The medium outlet 11 and the medium inlet 21 of the heat exchange device 20 are connected through a medium output pipeline 31. The medium return port 12 and the medium outlet 22 of the heat exchange device 20 are connected through a medium return pipeline 32, thereby realizing the connection between the medium channels of the heat storage device 10 and the heat exchange device 20.
[0047] Please see Figure 3 and Figure 4 The heat exchanger 20 is also equipped with a drinking water inlet 23, a drinking water outlet 24, and a water conveying channel (not shown in the figure) connecting the drinking water inlet 23 and the drinking water outlet 24. The water conveying channel is isolated from the medium channel. In specific applications, the water supply pipeline 34 is connected to the drinking water inlet 23. The drinking water in the water supply pipeline 34 flows into the water conveying channel from the drinking water inlet 23. In the water conveying channel, it exchanges heat with the heat exchange medium located in the medium channel to generate hot water. After that, the hot water flows out of the water conveying channel (i.e., out of the heat exchanger 20) from the drinking water outlet 24, and then is transported to the water user through the outlet pipeline 35.
[0048] In one embodiment, the medium outlet 22 is located above the heat exchange device 20 and connected to the inlet end of the medium return pipeline 32; the medium inlet 21 is located below the heat exchange device 20 and connected to the outlet end of the medium outlet pipeline 31. The drinking water inlet 23 is located above the heat exchange device 20 and is used to connect to the water supply pipeline 34; the drinking water outlet 24 is located below the heat exchange device 20 and is used to supply heated drinking water to the heat exchange device 20. Here, "above" and "below" refer to the vertical position of the water supply device 100 when it is placed on a horizontal plane.
[0049] Using the above technical solution, the heat exchange medium flows from bottom to top in the medium channel, while the drinking water flows from top to bottom in the water delivery channel. The flow directions of the heat exchange medium and the drinking water are opposite, which can fully facilitate heat exchange and make the generation of hot drinking water more efficient.
[0050] In one embodiment, the water circuit board 30 is disposed above the heat storage device 10, and the heat exchange device 20 is located on one side of the water circuit board 30 and the heat storage device 10. The medium output port 22 is correspondingly disposed to the liquid inlet end of the medium return pipe 32, and the drinking water input port 23 is correspondingly disposed to the water outlet of the water supply pipe 34. This facilitates the connection of the heat exchange device 20 to the water circuit board 30, and enables the medium return pipe 32 to communicate with the medium channel, and the water supply pipe 34 to communicate with the water delivery channel.
[0051] Please see Figures 1 to 3 The water supply device 100 also includes a connecting pipe 40, which is connected between the liquid outlet end of the medium output pipe 31 and the medium inlet 21 of the heat exchange device 20, and is used to connect the medium output pipe 31 and the medium channel.
[0052] Please see Figure 1 , Figure 3 and Figure 4 The water circuit board 30 also includes a flow meter 332, which is located beside the water supply pipe 34. The inlet of the flow meter 332 is connected to the water supply pipe 34, and the outlet of the flow meter 332 is connected to the drinking water inlet 23 of the heat exchange device 20. The flow meter 332 can be used to detect the flow rate of the water flowing through it. Integrating the flow meter 332 into the water circuit board 30 further improves the integration of the water circuit board 30 and helps to reduce the space occupied by the water supply device 100.
[0053] In one embodiment, the flow meter 332 is located on the side of the water supply pipe 34 near the water outlet pipe 35. This placement of the flow meter 332 on the side of the water supply pipe 34 near the water outlet pipe 35, compared to a design where the flow meter 332 is located on the side of the water supply pipe 34 away from the water outlet pipe 35, fully utilizes the space between the water circuit board 30 and the water supply pipe 34, improves the integration of the water circuit board 30, and helps to reduce the space occupied by the water circuit board 30.
[0054] In one embodiment, the medium output pipe 31, the medium return pipe 32, and the flow meter 332 are arranged side by side, with the medium return pipe 32 located between the medium output pipe 31 and the flow meter 332. This improves the regularity of the arrangement of the components of the water circuit board 30 and facilitates the connection of the flow meter 332, the heat exchange medium output pipe 31, and the heat exchange medium return pipe 32 with the heat exchange device 20.
[0055] Please see Figure 2 and Figure 6 The water circuit board 30 also includes a bridging pipe 36, which connects the water supply pipe 34 and the water outlet pipe 35 to allow water to flow from the water supply pipe 34 into the water outlet pipe 35. In this way, the water supply pipe 34 can supply drinking water to the heat exchanger 20 to generate hot water, and it can also supply room temperature water to the water outlet pipe 35. Conversely, the water outlet pipe 35 can supply both hot and room temperature water to the user, thus improving the utilization rate of both the water supply pipe 34 and the water outlet pipe 35.
[0056] Please see Figure 2 and Figure 3 The water circuit board 30 also includes a first valve body 333 and a second valve body 334. The first valve body 333 is used to control the connection or disconnection of the water supply pipe 34 and the water outlet pipe 35. The second valve body 334 is used to control the connection or disconnection of the water supply pipe 34 and the heat exchange device 20.
[0057] In specific implementation, when the first valve body 333 is opened and the second valve body 334 is closed, the water supply pipeline 34 is connected to the water outlet pipeline 35 and disconnected from the heat exchange device 20, thereby delivering room temperature water to the water outlet pipeline 35; when the first valve body 333 is closed and the second valve body 334 is opened, the water supply pipeline 34 is connected to the heat exchange device 20 and disconnected from the water outlet pipeline 35, thereby providing drinking water to the heat exchange device 20.
[0058] In one embodiment, the first valve body 333 is connected between the water supply pipe 34 and the bridging pipe 36. This arrangement of the first valve body 333 close to the water supply pipe 34 avoids occupying space around the outlet pipe 35, facilitating the placement of other components around the outlet pipe 35, such as the third valve body 335 and the fourth valve body 336 described below. Of course, in specific applications, as an alternative implementation, the first valve body 333 can also be connected between the bridging pipe 36 and the outlet pipe 35.
[0059] Please see Figure 2 and Figure 6 The water circuit board 30 also includes a water supply pipe 37. One end of the water supply pipe 37 is connected to the water supply pipe 34 or the water outlet pipe 35, and the other end of the water supply pipe 37 is connected to the heat storage device 10. The water supply pipe 37 is used to replenish water to the heat storage device 10. In this technical solution, the heat exchange medium in the heat storage device 10 is water. Since water generates steam after heating, to avoid increasing the gas pressure inside the heat storage device 10, the steam needs to be discharged from the heat storage device 10, which will reduce the amount of water in the heat storage device 10. Therefore, it is necessary to replenish water to the heat storage device 10 periodically or irregularly. By setting up the water supply pipe 37, water replenishment to the heat storage device 10 can be achieved. Furthermore, integrating the water supply pipe 37 into the water circuit board 30 further improves the integration of the water circuit board 30.
[0060] When the water supply pipe 37 is connected to the water supply pipe 34 and the heat storage device 10, it can supply room temperature water to the heat storage device 10; when the water supply pipe 37 is connected to the water outlet pipe 35 and the heat storage device 10, it can supply room temperature water or hot water to the heat storage device 10. In this embodiment, the water supply pipe 37 is connected to the water outlet pipe 35 and the heat storage device 10.
[0061] Please see Figure 5 and Figure 6 The heat storage device 10 is also equipped with a water inlet 13, and the water supply pipeline 37 is connected to the water inlet 13 to supply water to the heat storage device 10.
[0062] In one embodiment, please refer to Figure 2 and Figure 6The water supply pipeline 37 includes a first water supply branch 371 and a second water supply branch 372. The first water supply branch 371 is used to connect to the thermal storage device 10, and the second water supply branch 372 is used to connect to the cold water generating device (not shown in the figure). In this way, the water supply pipeline 37 can supply water to both the thermal storage device 10 and the cold water generating device. The cold water generating device can be an ice tank.
[0063] In practical applications, it is possible to first replenish the cold water generating device with water, and then replenish the heat storage device 10 with water after the cold water generating device is full. This can prevent the hot water in the heat storage device 10 from flowing into the cold water generating device after the heat storage device 10 is full.
[0064] Please see Figure 3 and Figure 6 The water circuit board 30 structure also includes a third valve body 335 and a fourth valve body 336. The third valve body 335 is used to control the connection or disconnection between the water outlet pipe 35 and the water supply end, and the fourth valve body 336 is used to control the connection or disconnection between the water outlet pipe 35 and the water supply pipe 37.
[0065] In specific implementation, when the third valve body 335 is opened and the fourth valve body 336 is closed, the water outlet pipe 35 is connected to the water user and disconnected from the water supply pipe 37, so that the water flow in the water outlet pipe 35 can be delivered to the water user; when the third valve body 335 is closed and the fourth valve body 336 is opened, the water outlet pipe 35 is connected to the water supply pipe 37 and disconnected from the water user, so that the water flow in the water outlet pipe 35 can be delivered to the water supply pipe 37.
[0066] In one embodiment, the connection between the water supply pipe 37 and the water outlet pipe 35 is located upstream of the connection between the water user and the water outlet pipe 35. The third valve body 335 is connected to the water outlet pipe 35 and is close to the connection between the water user and the water outlet pipe 35. The fourth valve body 336 is connected between the water outlet pipe 35 and the water supply pipe 37.
[0067] Please see Figure 3 and Figure 5 The water circuit board 30 also includes an exhaust pipe 38, which is connected to the heat storage device 10 and used to discharge steam inside the heat storage device 10. When the heat exchange medium is water, steam is generated after heating. When the steam reaches a certain level, the pressure inside the heat storage container increases, posing a potential hazard. By providing an exhaust pipe 38 to discharge the steam inside the heat storage device 10, the safety of the heat storage device 10 is improved. Specifically, the heat storage device 10 is also provided with an exhaust port 14, and the exhaust pipe 38 is connected to the exhaust port 14 so that the steam inside the heat storage device 10 enters the exhaust pipe 38 through the exhaust port 14.
[0068] Please see Figures 1 to 4The water supply device 100 also includes a heating device 50, which is located downstream of the heat exchange device 20 and is used to heat the drinking water from the heat exchange device 20. Specifically, the inlet of the heating device 50 is connected to the drinking water outlet 24 of the heat exchange device 20, and the outlet of the heating device 50 is connected to the outlet pipe 35. By using the heat exchange device 20 and the heating device 50 to heat the drinking water, the heating effect of the drinking water can be improved, enabling a large flow of hot water for drinking. The hot water does not need to be preheated and stored, meaning the water output is always "fresh" hot water. Of course, in other embodiments, the water supply device 100 may not include the heating device 50.
[0069] Please see Figure 1 and Figure 2 The water supply device 100 also includes a housing 60, a water circuit board 30, a heat exchange device 20, a heat storage device 10, and a heating device 50, all of which are located inside the housing 60. The water supply device 100 is generally rectangular.
[0070] 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.
