[0002] In order to better meet people's needs, current water purification and supply devices are usually equipped with hot water tanks and / or ice tanks. The heat exchange medium in the hot water tank can flow with drinking water in two adjacent and isolated flow channels and exchange heat, so that cold drinking water or normal temperature drinking water can be converted into hot water. The ice tank can convert hot water or normal temperature water into cold water. Therefore, the water purification and supply device can supply both hot water and cold water, expanding the scope of use of the water purification and supply device.

[0035] 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

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] The water supply device is usually provided with a hot water tank and / or an ice tank. After the water supply device has been used for a period of time, the water in the hot water tank and the ice tank will decrease, so it is necessary to replenish water regularly or irregularly. In the related art, only water of one temperature can be provided for the hot water tank and / or the ice tank, which limits the performance of the water supply device or consumes a lot of energy. For example, when only normal temperature water can be supplied to the hot water tank, the heating component in the hot water tank requires more energy to heat the water in the hot water tank compared to the technical solution of supplying hot water to the hot water tank; or, when only normal temperature water can be supplied to the ice tank, the ice tank cannot be sterilized and disinfected compared to the technical solution of supplying hot water to the ice tank.

[0041] In view of this, the present invention provides a waterway plate structure and a water supply device. The water supply device includes a waterway plate structure. A water outlet pipeline and a water replenishment pipeline connected to the water outlet pipeline are arranged on the waterway plate structure. The water outlet pipeline can transport both a first water body and a second water body, so that the water replenishment pipeline can replenish the first water body for the water-requiring component and replenish the second water body for the water-requiring component, thereby expanding the performance of the water supply device and reducing energy consumption.

[0042] See also Figure 1 and Figure 2 The water supply device provided in the embodiment of the present invention includes a waterway plate structure 100, a heat exchanger 200 and a water-requiring component 300. The heat exchanger 200 is used to allow a 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 heat exchanger 200 to exchange heat, thereby generating drinking hot water. The water-requiring component 300 may be a first tank (not shown) and / or a second tank 301. The first tank is used to cool the water flowing through, thereby generating drinking cold water. The second tank 301 stores a heat exchange medium (water) for heat exchange with drinking water. In a specific application, the first tank may be an ice tank, and the second tank 301 may be a hot water tank.

[0043] See also Figure 2 and Figure 3The heat exchanger 200 is provided with a drinking water channel (not marked in the figure), a drinking water inlet 201, a drinking water outlet 202, a medium channel (not marked in the figure), a medium flow inlet 203 and a medium flow outlet 204. The drinking water channel and the medium channel are adjacent and isolated. The drinking water inlet 201 and the drinking water outlet 202 are respectively connected to the drinking water channel, and the medium flow inlet 203 and the medium flow outlet 204 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. The second tank 301 is connected to the medium channel. The heat exchange medium in the second tank 301 can flow into the medium channel, and after heat exchange with the drinking water in the drinking water channel, it flows back to the second tank 301.

[0044] See also Figures 3 to 5 The waterway plate structure 100 includes a water outlet pipe 10, and the water outlet pipe 10 is provided with a water outlet portion 11, a first input portion 12 and a second input portion 13. The first input portion 12 and the second input portion 13 are both arranged upstream of the water outlet portion 11. The water outlet portion 11 is used to connect to a water-using end (such as a faucet), the first input portion 12 is used to supply a first water body to flow into the water outlet pipe 10, and the second input portion 13 is used to supply a second water body to flow into the water outlet pipe 10. The first water body may be hot water, and the second water body may be water at room temperature. Specifically, the first input portion 12 is connected to the drinking water outlet 202 of the heat exchanger 200, so that the drinking water (first water body) flowing through the heat exchanger 200 flows into the water outlet pipe 10 from the drinking water outlet 202 of the heat exchanger 200.

[0045] By providing the first input portion 12 and the second input portion 13 in the water outlet pipe 10, the first water body and the second water body can flow into the water outlet pipe 10. Therefore, the water outlet pipe 10 can output both the first water body and the second water body.

[0046] See also Figure 2 , Figure 5 and Figure 6The waterway plate structure 100 further includes a water replenishment pipeline 20, which is used to replenish water for the water-demanding component 300. The water outlet pipeline 10 is also provided with a water replenishment portion 14, and the first input portion 12 and the second input portion 13 are both arranged upstream of the water replenishment portion 14, and the water replenishment pipeline 20 is connected to the water replenishment portion 14. In this way, the water replenishment pipeline 20 connects the water replenishment portion 14 of the water outlet pipeline 10 and the water-demanding component 300, so that the water flow in the water outlet pipeline 10 can flow into the water-demanding component 300 to replenish water for the water-demanding component 300. Since the water outlet pipeline 10 can output both the first water body and the second water body, it can replenish both the first water body and the second water body for the water-demanding component 300, thereby expanding the performance of the water supply device and reducing energy consumption. Furthermore, the water outlet pipeline 10 and the water supply pipeline 20 are both arranged on the waterway plate structure 100, which improves the integration of the waterway plate structure 100 and helps to reduce the occupied space of the water supply device.

[0047] In specific implementation, when the water-requiring component 300 is the second tank 301, the first water body can be selected to be supplemented for the second tank 301 to reduce the energy consumption of the heating component in the second tank 301 for heating the heat exchange medium; when the water-requiring component 300 is the first tank, when the first tank is in normal use, the second water body can be selected to be supplemented for the first tank to reduce the energy consumption of the first tank, and when the first tank needs to be sterilized, the first water body can be selected to be supplemented for the first tank to achieve sterilization and disinfection of the first tank; when the water-requiring component 300 is the second tank 301 and the first tank, one method is to use different pipelines to connect the second tank 301 and the first tank to the water outlet pipeline 10, and replenish the first water body and cold water to the second tank 301 and the first tank at different times, and another method is to use a common pipeline to connect the second tank 301 and the first tank to the water outlet pipeline 10. Since the water in the first tank is provided to the water-using end, causing the water volume to decrease, and the water in the second tank 301 is reduced due to evaporation, the water volume reduced in the first tank is greater than the water volume reduced in the second tank 301. Therefore, when the water-requiring component 300 is the second tank 301 and the first tank, and a common pipeline is used to connect the water outlet pipeline 10, when the first tank is in normal use, the second water body can be selected to be provided to the second tank 301 and the first tank, and when the first tank needs to be disinfected, the first water body can be selected to be provided to the second tank 301 and the first tank.

[0048] See also Figure 4 and Figure 5 The waterway plate structure 100 also includes a first control valve 31 and a second control valve 32. The first control valve 31 is used to control the connection or disconnection between the water outlet pipeline 10 and the water use end, and the second control valve 32 is used to control the connection or disconnection between the water outlet pipeline 10 and the water supply pipeline 20.

[0049] In specific implementation, when the first control valve 31 is opened and the second control valve 32 is closed, the water outlet pipeline 10 is connected to the water use end and is disconnected from the water supply pipeline 20, so that the water flow in the water outlet pipeline 10 can be transported to the water use end; when the first control valve 31 is closed and the second control valve 32 is opened, the water outlet pipeline 10 is connected to the water supply pipeline 20 and is disconnected from the water use end, so that the water flow in the water outlet pipeline 10 can be transported to the water supply pipeline 20.

[0050] In one embodiment, the water replenishment part 14 is arranged upstream of the water outlet part 11, and the first control valve 31 is connected to the water outlet pipeline 10 and is located between the water outlet part 11 and the water replenishment part 14. The first control valve 31 is used to control the connection or disconnection of the water outlet pipeline 10 between the water replenishment part 14 and the water outlet part 11. When the first control valve 31 is opened, the water outlet pipeline 10 between the water replenishment part 14 and the water outlet part 11 is connected, the water outlet pipeline 10 is connected with the water use end, and the water flow in the water outlet pipeline 10 can be transported to the water use end; when the first control valve 31 is closed, the water outlet pipeline 10 between the water replenishment part 14 and the water outlet part 11 is disconnected, the water outlet pipeline 10 is disconnected with the water use end, and the water flow in the water outlet pipeline 10 cannot be transported to the water use end. The second control valve 32 is connected between the water replenishment part 14 and the water replenishment pipeline 20, and is used to control the connection or disconnection of the water replenishment part 14 and the water replenishment pipeline 20. When the second control valve 32 is opened, the water replenishment part 14 is connected to the water replenishment pipeline 20, that is, the water outlet pipeline 10 is connected to the water replenishment pipeline 20; when the second control valve 32 is closed, the water replenishment part 14 is disconnected from the water replenishment pipeline 20, that is, the water outlet pipeline 10 is disconnected from the water replenishment pipeline 20.

[0051] See also Figure 5 and Figure 6 The waterway plate structure 100 further includes a water inlet pipeline 40, which is provided with a water inlet portion 41 and a first output portion 42, wherein the water inlet portion 41 is used to connect to a water source, and the first output portion 42 is used to connect to the second input portion 13. In this way, the water inlet pipeline 40 can be used to transport the second water body to the water outlet pipeline 10. In addition, the water inlet pipeline 40 is provided in the waterway plate structure 100, so as to further improve the integration of the waterway plate structure 100, and is conducive to reducing the occupied space of the water supply device.

[0052] See also Figures 4 to 6 The waterway plate structure 100 further includes a third control valve 33, which is used to control the connection or disconnection between the first output portion 42 and the second input portion 13. That is, the third control valve 33 is used to control the connection or disconnection between the water inlet pipeline 40 and the water outlet pipeline 10. When the third control valve 33 is opened, the water inlet pipeline 40 and the water outlet pipeline 10 are connected, and the water inlet pipeline 40 can transport the second water body to the water outlet pipeline 10; when the third control valve 33 is closed, the water inlet pipeline 40 and the water outlet pipeline 10 are disconnected.

[0053] See also Figures 4 to 6 The waterway plate structure 100 also includes a bridge pipe 50, which is connected between the first output portion 42 and the second input portion 13, and the third control valve 33 is used to control the connection or disconnection between the bridge pipe 50 and the water inlet pipe 40. By setting the third control valve 33 to control the connection or disconnection between the bridge pipe 50 and the water inlet pipe 40, the third control valve 33 controls the connection or disconnection between the water inlet pipe 40 and the water outlet pipe 10. Specifically, the third control valve 33 is connected between the first output portion 42 and the bridge pipe 50. It can be understood that in other embodiments, the third control valve 33 can also be connected between the bridge pipe 50 and the second input portion 13 to control the connection or disconnection between the bridge pipe 50 and the water outlet pipe 10.

[0054] In one embodiment, the water inlet pipeline 40 and the water outlet pipeline 10 are arranged in parallel. In this way, the regularity of the arrangement of the water inlet pipeline 40 and the water outlet pipeline 10 can be improved, which is convenient for other pipelines to be arranged in the waterway plate structure 100, further improving the integration of the waterway plate structure 100, and helping to reduce the occupied space of the water supply device. In this embodiment, the water inlet pipeline 40 and the water outlet pipeline 10 both extend along the first direction X, and are arranged adjacently along the second direction Y. The waterway plate structure 100 has a first end 100a and a second end 100b that are arranged oppositely along the first direction X. The water outlet portion 11 of the water outlet pipeline 10 and the water inlet portion 41 of the water inlet pipeline 40 are both arranged at the first end 100a of the waterway plate structure 100. Among them, the first direction X is the length direction of the waterway plate structure 100, and the second direction Y is the width direction of the waterway plate structure 100.

[0055] In one embodiment, the second input portion 13 is disposed downstream of the first input portion 12, and the waterway plate structure 100 further includes a first one-way valve 35, which is used to allow water to flow from the water inlet pipe 40 to the water outlet pipe 10 in one direction. Specifically, the first one-way valve 35 is disposed in the bridge pipe 50.

[0056] The second input part 13 is arranged downstream of the first input part 12, and the water outlet part 11 and the water replenishment part 14 are arranged downstream of the first input part 12. In this way, the first input part 12 can be arranged at the end of the water outlet pipeline 10 (i.e., the end of the water outlet pipeline 10 close to the second end 100b), so that the first water body can flow through the entire water outlet pipeline 10, thereby achieving sterilization of the water outlet pipeline 10. Since the first water body is output through the drinking water outlet 202 of the heat exchanger 200 and flows into the water outlet pipeline 10 from the first input part 12 of the water outlet pipeline 10, it will pass through the second input part 13 and may flow to the water inlet pipeline 40. By setting the first one-way valve 35, the first water body can be prevented from flowing to the water inlet pipeline 40 through the bridge pipeline 50.

[0057] See also Figure 3 and Figure 6 The water inlet pipeline 40 is also provided with a second output portion 43, and the second output portion 43 is used to connect to the drinking water inlet 201 of the heat exchanger 200. In this way, the water inlet pipeline 40 can also transport drinking water to the heat exchanger 200. Of course, in other embodiments, the water inlet pipeline 40 may not be provided with the second output portion 43.

[0058] In this embodiment, the water inlet portion 41, the first output portion 42 and the second output portion 43 of the water inlet pipeline 40 are sequentially arranged in the water inlet pipeline 40 along the direction from the first end 100a to the second end 100b, and the water outlet portion 11, the second input portion 13 and the first input portion 12 of the water outlet pipeline 10 are sequentially arranged in the water outlet pipeline 10 along the direction from the first end 100a to the second end 100b. In this way, the second output portion 43 of the water inlet pipeline 40 and the first input portion 12 of the water outlet pipeline 10 are both arranged close to the second end 100b, that is, close to the same side of the waterway plate structure 100, which helps to connect the water inlet pipeline 40 and the water outlet pipeline 10 with the heat exchanger 200.

[0059] See also Figure 3 and Figure 4 The waterway plate structure 100 further includes a fourth control valve 34, which is used to control the connection or disconnection between the water inlet pipeline 40 and the heat exchanger 200. When the fourth control valve 34 is opened, the water inlet pipeline 40 is connected to the heat exchanger 200, and the water inlet pipeline 40 can transport drinking water to the heat exchanger 200; when the fourth control valve 34 is closed, the water inlet pipeline 40 is disconnected from the heat exchanger 200.

[0060] During specific implementation, the third control valve 33 can be opened and the fourth control valve 34 can be closed to enable the water inlet pipeline 40 to transport the second water body to the water outlet pipeline 10; or, the third control valve 33 can be closed and the fourth control valve 34 can be opened to enable the water inlet pipeline 40 to transport drinking water to the heat exchanger 200.

[0061] See also Figure 3 , Figure 4 and Figure 6 The waterway plate structure 100 further includes a flow meter 60, one end of which is used to connect to the second output portion 43, and the other end of which is used to connect to the drinking water inlet 201 of the heat exchanger 200. The flow meter 60 can be used to detect the flow rate of water flowing through. The flow meter 60 is arranged on the waterway plate structure 100, which further improves the integration of the waterway plate structure 100 and helps to reduce the occupied space of the water supply device.

[0062] See also Figure 2 and Figure 5, the water replenishment pipeline 20 includes a first branch 21 and a second branch 22, the first branch 21 is used to replenish water for the first tank, the second branch 22 is used to replenish water for the second tank 301, and the first tank and the second tank 301 are both water-requiring components 300. Of course, in other embodiments, the water replenishment pipeline 20 may also include the first branch 21, and the water-requiring component 300 is the first tank; or the water replenishment pipeline 20 may also include the second branch 22, and the water-requiring component 300 is the second tank 301.

[0063] In one embodiment, the waterway plate structure 100 further includes a second one-way valve (not shown), which is disposed in the second branch 22 and is used to allow water to flow into the second tank 301 along the second branch 22 in one direction. In this way, the first water body in the second tank 301 cannot flow into the first tank, thereby preventing the first water body in the second tank 301 from flowing into the first tank due to overfilling, thereby increasing the energy consumption of the first tank.

[0064] During specific implementation, a second one-way valve is set in the second branch 22, the resistance of the first branch 21 is smaller than the resistance of the second branch 22, and the water flows through the first branch 21 to replenish the first tank with water. After the first tank is filled or reaches the preset water level, the water flows through the second branch 22 to replenish the second tank 301 with water.

[0065] It is understood that in other embodiments, the waterway plate structure 100 may further include a switch valve, which is provided in the first branch 21 and / or the second branch 22. In specific applications, the first branch 21 and / or the second branch 22 may be turned on or off by controlling the opening or closing of the switch valve.

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

[0067] See also Figure 2 , Figure 3 and Figure 5 The water supply device also includes a heater 400, which is arranged downstream of the heat exchanger 200 and is used to heat the drinking water from the heat exchanger 200. Specifically, the water inlet end of the heater 400 is connected to the drinking water outlet 202 of the heat exchanger 200, and the water outlet end of the heater 400 is connected to the first input part 12 of the water outlet pipeline 10. 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 first water body can be achieved. The drinking first water body does not need to be heated and stored in advance, that is, the water outlet is all "fresh" first water body. Of course, in other embodiments, the water supply device may not be provided with the heater 400, or, when the water supply device is not provided with the heat exchanger 200, the water inlet end of the heater 400 is connected to the water inlet pipeline 40.

[0068] In one embodiment, the water supply device further includes a shell 500, and the waterway plate structure 100, the heat exchanger 200, the water demanding component 300 and the heater 400 are all arranged in the shell 500, and the water supply device is a rectangular parallelepiped as a whole.

[0069] When the waterway plate structure 100 is used to provide the first water body for the water-using end, the first control valve 31 and the fourth control valve 34 are controlled to be open, and the second control valve 32 and the third control valve 33 are closed. The second water body flows into the water inlet pipe 40 through the water inlet portion 41 of the water inlet pipe 40, and then flows to the heat exchanger 200 and the heater 400. After being processed to generate the first water body, it flows into the water outlet pipe 10 through the first input portion 12 of the water outlet pipe 10, and then flows to the water-using end through the water outlet portion 11 of the water outlet pipe 10.

[0070] When the waterway plate structure 100 is used to provide the first water body for the water-requiring component 300, the second control valve 32 and the fourth control valve 34 are controlled to be open, and the first control valve 31 and the third control valve 33 are closed. The second water body flows into the water inlet pipe 40 through the water inlet portion 41 of the water inlet pipe 40, and then flows to the heat exchanger 200 and the heater 400. After being processed to generate the first water body, it flows into the water outlet pipe 10 through the first input portion 12 of the water outlet pipe 10, and then flows into the water replenishment pipe 20 through the water replenishment portion 14 of the water outlet pipe 10, and is further transported to the water-requiring component 300.

[0071] When the waterway plate structure 100 is used to provide the second water body for the water-using end, the first control valve 31 and the third control valve 33 are controlled to be open, and the second control valve 32 and the fourth control valve 34 are closed, and the second water body flows into the water inlet pipe 40 through the water inlet portion 41 of the water inlet pipe 40, and then flows into the bridge pipe 50 through the first output portion 42 of the water inlet pipe 40, and then flows into the water outlet pipe 10 through the second input portion 13 of the water outlet pipe 10, and finally flows to the water-using end through the water outlet portion 11 of the water outlet pipe 10.

[0072] When the waterway plate structure 100 is used to provide a second water body for the water-requiring component 300, the second control valve 32 and the third control valve 33 are controlled to be open, and the first control valve 31 and the fourth control valve 34 are closed. The second water body flows into the water inlet pipe 40 through the water inlet portion 41 of the water inlet pipe 40, and then flows into the bridge pipe 50 through the first output portion 42 of the water inlet pipe 40, and then flows into the water outlet pipe 10 through the second input portion 13 of the water outlet pipe 10, and then flows into the water replenishment pipe 20 through the water replenishment portion 14 of the water outlet pipe 10, and is then transported to the water-requiring component 300.

[0073] Among them, after the water flow (the first water body or the second water body) flows into the water replenishment pipeline 20 through the water replenishment part 14 of the water outlet pipeline 10, the water flows along the first branch 21 to replenish the first tank with water. When the first tank is filled with water or the first tank is replenished to a preset water level, the water flows along the second branch 22 to replenish the second tank 301 with water.
