[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] Water supply devices are increasingly widely used because they can provide both hot water and cooling water. After a period of use, or when the water supply device has not been used for a long time, the first tank used to generate cooling water is prone to produce substances harmful to human health, so it needs to be sterilized. However, the first tank in the related art is either impossible to disinfect or inconvenient to disinfect, which poses a health hazard to the user or brings a bad user experience.

[0037] 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 treatment device and a first tank. A pipeline connecting the water treatment device and the first tank is provided on the waterway plate structure, so that hot water can be transported to the first tank, so that the hot water can sterilize and disinfect the first tank, greatly improving the convenience of disinfecting the first tank.

[0038] See also Figure 1 and Figure 2 The water supply device provided by the embodiment of the present invention includes a waterway plate structure 100, a water treatment device 200 and a first tank 300, and the waterway plate structure 100 is connected between the water treatment device 200 and the first tank 300.

[0039] The water treatment device 200 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 200 to exchange heat, thereby generating hot water. Figure 3 The water treatment device 200 is provided with a drinking water channel (not marked in the figure), a first inlet 201, a first outlet 202, a medium channel (not marked in the figure), a second inlet 203 and a second outlet 204. The drinking water channel and the medium channel are adjacent and isolated. The first inlet 201 and the first outlet 202 are respectively connected to the drinking water channel, and the second inlet 203 and the second 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. When the heat exchange medium and normal temperature drinking water are controlled to flow through the water treatment device 200 at the same time, heat exchange is performed between the two, so that the normal temperature drinking water is generated into hot drinking water.

[0040] See also Figure 1 and Figure 2 The water supply device further includes a second tank 400, in which a heat exchange medium is stored, and the second tank 400 is connected to the medium channel of the water treatment device 200. The heat exchange medium in the second tank 400 can flow into the medium channel, exchange heat with the drinking water in the drinking water channel, and then flow back into the second tank 400. The second tank 400 can be a hot water tank, and the heat exchange medium can be water or heat transfer oil.

[0041] Specifically, see Figure 3 and Figure 4 The second tank 400 is provided with a discharge port 401 and a reflux port 402. The discharge port 401 and the second inlet 203 of the water treatment device 200 are connected through a pipeline, and the reflux port 402 and the second outlet 204 of the water treatment device 200 are connected through a pipeline, thereby realizing that the second tank 400 is connected to the medium channel of the water treatment device 200.

[0042] The first tank 300 may be a device for generating cold water, which may be connected to a water-using end to provide cold water to the water-using end. In one embodiment, the first tank 300 is an ice container.

[0043] See also Figure 3 and Figure 5 The waterway plate structure 100 includes a water outlet pipe 10, which is used to connect at least the water-using end and the first outlet 202 of the water treatment device 200 to provide hot water for the water-using end. Specifically, the first outlet 202 of the water treatment device 200 is connected to the water outlet pipe 10 to provide hot water for the water outlet pipe 10, so that the water outlet pipe 10 can provide hot water for the water-using end.

[0044] See also Figure 2 , Figure 6 and Figure 7 The waterway plate structure 100 further includes a first water supply pipeline 20 and a bridge pipeline 30. The first water supply pipeline 20 is used to communicate with the first tank 300 and provide water flow to the first tank 300, that is, the first tank 300 receives the water flow from the first water supply pipeline 20. The bridge pipeline 30 connects the water outlet pipeline 10 and the first water supply pipeline 20, so that the hot water in the water outlet pipeline 10 can flow through the bridge pipeline 30 and the first water supply pipeline 20 and flow into the first tank 300.

[0045] When hot water is provided to the user end, the hot water can be controlled to flow from the water treatment device 200 into the water outlet pipe 10 and then flow to the user end. When hot water is provided to the first tank 300, the hot water can be controlled to flow from the water treatment device 200 into the water outlet pipe 10 and then flow through the bridge pipe 30 and the first water supply pipe 20 in sequence and then flow to the first tank 300.

[0046] By adopting the above technical solution, by setting the water outlet pipe 10 to connect the first outlet 202 of the water treatment device 200, hot water can flow into the water outlet pipe 10. By setting the bridge pipe 30 to connect the water outlet pipe 10 and the first water replenishment pipe 20, the hot water in the water outlet pipe 10 can flow into the first water replenishment pipe 20, and then the first water replenishment pipe 20 can provide hot water for the first tank 300. When the hot water flows through the first tank 300, the hot water can sterilize and disinfect the first tank 300. In a specific application, when the first tank 300 needs to be sterilized and disinfected, the hot water in the water outlet pipe 10 can be controlled to flow to the bridge pipe 30, and then can flow into the first tank 300 through the first water replenishment pipe 20. This disinfection method is simple and fast, does not require the user to perform cumbersome operations, and greatly improves the user's experience.

[0047] In one embodiment, the water outlet pipe 10 and the first water replenishment pipe 20 both extend along the first direction X, the bridge pipe 30 extends along the second direction Y, and the first water replenishment pipe 20 and the bridge pipe 30 are both arranged adjacent to the water outlet pipe 10 along the third direction Z. The waterway plate structure 100 has a first end 100a and a second end 100b arranged opposite to each other along the first direction X, and the part where the water outlet pipe 10 is connected to the water end (i.e., the water outlet end of the water outlet pipe 10) and the part where the first water replenishment pipe 20 is connected to the first tank 300 (i.e., the water outlet end of the first water replenishment pipe 20) are both formed 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, the second direction Y is the width direction of the waterway plate structure 100, and the third direction Y is the height direction of the waterway plate structure 100. Specifically, the first water replenishment pipe 20 and the bridge pipe 30 are both arranged below the water outlet pipe 10. The first water replenishment pipeline 20 and the bridge pipeline 30 are both arranged adjacent to the water outlet pipeline 10 along the third direction Z, and the space of the waterway plate structure 100 in the height direction can be utilized to increase the integration of the waterway plate structure 100. The water outlet end of the water outlet pipeline 10 and the water outlet end of the first water replenishment pipeline 20 are both formed at the first end 100a of the waterway plate structure 100, which is conducive to the connection between the waterway plate structure 100 and the water use end and the first tank 300.

[0048] See also Figure 5 and Figure 6 The waterway plate structure 100 also includes a first valve body 41 and a second valve body 42. The first valve body 41 is used to control the connection and disconnection between the water outlet pipeline 10 and the water end, and the second valve body 42 is used to control the connection and disconnection between the water outlet pipeline 10 and the bridge pipeline 30.

[0049] In specific implementation, when the first valve body 41 is opened and the second valve body 42 is closed, the water outlet pipe 10 is connected to the water use end and is disconnected from the bridge pipe 30, so that the water flow in the water outlet pipe 10 can be delivered to the water use end; when the first valve body 41 is closed and the second valve body 42 is opened, the water outlet pipe 10 is connected to the bridge pipe 30 and is disconnected from the water use end, so that the water flow in the water outlet pipe 10 can be delivered to the bridge pipe 30.

[0050] In one embodiment, the portion where the water outlet pipe 10 is connected to the water end is located downstream of the portion where the water outlet pipe 10 is connected to the bridge pipe 30, the first valve body 41 is connected to the water outlet pipe 10 and is located downstream of the portion where the water outlet pipe 10 is connected to the bridge pipe 30, and the second valve body 42 is connected between the water outlet pipe 10 and the bridge pipe 30. It can be understood that in other embodiments, the portion where the water outlet pipe 10 is connected to the water end can also be located upstream of the portion where the water outlet pipe 10 is connected to the bridge pipe 30.

[0051] In one embodiment, the first valve body 41 and the second valve body 42 are arranged on a side of the water outlet pipe 10 away from the bridge pipe 30 and the first water supply pipe 20 along the third direction Z. That is, the first valve body 41 and the second valve body 42 are both arranged above the water outlet pipe 10. In this way, the space of the waterway plate structure 100 in the thickness direction is fully utilized, the integration of the waterway plate structure 100 is increased, and the occupied space of the waterway plate structure 100 is reduced.

[0052] See also Figure 2 and Figure 5 The waterway plate structure 100 also includes a water inlet pipe 50, which is used to connect the water source and the water outlet pipe 10 to provide normal temperature water for the water outlet pipe 10. In this way, the water outlet pipe 10 can not only transport hot water, but also transport normal temperature water. Since the first tank 300 is connected to the water end and provides cooled drinking water for the water end, the water in the first tank 300 will often decrease and needs to be replenished frequently. By setting the water inlet pipe 50 to transport normal temperature water to the water outlet pipe 10, it is possible to realize that the water outlet pipe 10 transports normal temperature water to the first tank 300. Compared with the technical solution of replenishing hot water for the first tank 300, the first tank 300 consumes less energy to cool the water therein.

[0053] In a specific application, when the first tank 300 needs to be disinfected, the water treatment device 200 can be controlled to be connected with the water outlet pipe 10, and hot water flows from the water treatment device 200 into the water outlet pipe 10, and then flows into the first tank 300 through the bridge pipe 30 and the first water replenishment pipe 20, thereby achieving sterilization and disinfection of the first tank 300. When the first tank 300 needs to be replenished with water, the water inlet pipe 50 can be controlled to be connected with the water outlet pipe 10, and normal temperature water flows from the water inlet pipe 50 into the water outlet pipe 10, and then flows into the first tank 300 through the bridge pipe 30 and the first water replenishment pipe 20, thereby achieving water replenishment of the first tank 300.

[0054] The water source input into the water inlet pipeline 50 may be purified water filtered through an RO membrane.

[0055] In one embodiment, the water inlet pipeline 50 is also used to connect the water source and the first inlet 201 of the water treatment device 200. In this way, the water inlet pipeline 50 can also deliver drinking water to the water treatment device 200. Of course, in other embodiments, the water inlet pipeline 50 may also be arranged not to connect to the water treatment device 200.

[0056] In this embodiment, the water inlet pipeline 50 is 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.

[0057] In one embodiment, the water inlet pipeline 50 extends along the first direction X and is arranged adjacent to the water outlet pipeline 10 along the second direction Y. The portion of the water inlet pipeline 50 for connecting to the water source (i.e., the water inlet end of the water inlet pipeline 50) is formed at the first end 100a of the waterway plate structure 100, and the portion of the water inlet pipeline 50 for connecting to the first inlet 201 of the water treatment device 200 (i.e., the water outlet end of the water inlet pipeline 50) is disposed near the second end 100b of the waterway plate structure 100.

[0058] See also Figure 1 and Figure 5 The waterway plate structure 100 further includes a third valve body 43 and a fourth valve body 44. The third valve body 43 is used to control the connection or disconnection between the water inlet pipeline 50 and the water outlet pipeline 10. When the third valve body 43 is opened, the water inlet pipeline 50 and the water outlet pipeline 10 are connected, and the water inlet pipeline 50 can transport normal temperature water to the water outlet pipeline 10; when the third valve body 43 is closed, the water inlet pipeline 50 and the water outlet pipeline 10 are disconnected. The fourth valve body 44 is used to control the connection or disconnection between the water inlet pipeline 50 and the water treatment device 200. When the fourth valve body 44 is opened, the water inlet pipeline 50 and the water treatment device 200 are connected, and the water inlet pipeline 50 can transport drinking water to the water treatment device 200; when the fourth valve body 44 is closed, the water inlet pipeline 50 and the water treatment device 200 are disconnected.

[0059] During specific implementation, the third valve body 43 can be opened and the fourth valve body 44 can be closed to enable the water inlet pipeline 50 to transport normal temperature water to the water outlet pipeline 10; or, the third valve body 43 can be closed and the fourth valve body 44 can be opened to enable the water inlet pipeline 50 to transport drinking water to the water treatment device 200.

[0060] The first valve body 41 , the second valve body 42 , the third valve body 43 and the fourth valve body 44 are all solenoid valves.

[0061] When the heat exchange medium in the second tank 400 is water, steam is easily formed due to the high temperature. For safety reasons, the steam will be discharged from the second tank 400, so the heat exchange medium in the second tank 400 will be reduced, and water needs to be replenished regularly or irregularly.

[0062] Please refer to question 1. Figures 4 to 6 The waterway plate structure 100 also includes a second water replenishment pipeline 60, which is used to connect the second tank 400 and provide water flow for the second tank 400. The bridge pipe 30 also connects the water outlet pipe 10 and the second water replenishment pipeline 60, so that the hot water in the water outlet pipe 10 can flow through the bridge pipe 30 and the second water replenishment pipeline 60 and flow into the second tank 400. By setting the second water replenishment pipeline 60 to connect the second tank 400, water replenishment for the second tank 400 can be achieved. Among them, the second water replenishment pipeline 60 extends along the third direction Z. Specifically, the second tank 400 is also provided with a water replenishment port 403, and the second water replenishment pipeline 60 is connected to the water replenishment port 403. When this technical solution is adopted, the heat exchange medium in the second tank 400 is water.

[0063] In one embodiment, the first water replenishment pipeline 20, the water outlet pipeline 10, and the second water replenishment pipeline 60 are arranged in sequence along the extension direction of the bridge pipeline 30. In this way, the bridge pipeline 30 is connected to the water outlet pipeline 10 and the first water replenishment pipeline 20, and the water outlet pipeline 10 and the second water replenishment pipeline 60. It can be understood that in other embodiments, the water outlet pipeline 10, the first water replenishment pipeline 20, and the second water replenishment pipeline 60 can also be arranged in sequence along the extension direction of the bridge pipeline 30, or the water outlet pipeline 10, the second water replenishment pipeline 60 and the first water replenishment pipeline 20 can be arranged in sequence along the extension direction of the bridge pipeline 30. In specific applications, it can be designed according to the setting positions of the second tank 400 and the first tank 300.

[0064] By setting up a bridge pipe 30 to achieve the connection between the water outlet pipe 10 and the first water replenishment pipe 20, and the connection between the water outlet pipe 10 and the second water replenishment pipe 60, the flexibility of setting the first water replenishment pipe 20 and the second water replenishment pipe 60 can be improved, that is, the flexibility of setting the second tank 400 and the first tank 300 can be improved.

[0065] In one embodiment, the waterway plate structure 100 further includes a one-way valve (not shown), which is arranged at one end of the bridge pipe 30 close to the second water supply pipe 60 or at the second water supply pipe 60. With such arrangement, on the one hand, when the water in the first tank 300 does not reach the preset water level, the water flow resistance of the first water supply pipe 20 can be made smaller than the water flow resistance of the second water supply pipe 60, and the first tank 300 can be preferably replenished; on the other hand, the hot water in the second tank 400 cannot flow into the first tank 300, so as to avoid the increase of energy consumption of the first tank 300 due to the excessive flow of hot water in the second tank 400 to the first tank 300; on the third hand, the hot air in the second tank 400 cannot flow into the first water supply pipe 20 or the water outlet pipe 10.

[0066] In specific implementation, the resistance of the first water replenishment pipeline 20 is smaller than the resistance of the second water replenishment pipeline 60, and the water first flows through the first water replenishment pipeline 20 to replenish the first tank 300 with water. After the first tank 300 is filled, the water flows through the second water replenishment pipeline 60 to replenish the second tank 400 with water.

[0067] It is understood that in other embodiments, the waterway plate structure 100 may further include a switch valve, which is provided in the first water supply pipeline 20 and / or the second water supply pipeline 60. In specific applications, the first water supply pipeline 20 and / or the second water supply pipeline 60 may be turned on or off by controlling the opening or closing of the switch valve.

[0068] See also Figure 7 , the bridge pipe 30 is provided with a plugging port 31 connected to the outside, and the portion of the bridge pipe 30 close to the plugging port 31 extends along the axial direction of the plugging port 31. The waterway plate structure 100 also includes a plugging member 45, and the plugging member 45 seals the plugging port 31. By providing the plugging port 31, it is beneficial to injection molding the bridge pipe 30. By providing the plugging member 45 to seal the plugging port 31, water is prevented from flowing out of the plugging port 31. The cooperation between the plugging port 31 and the plugging member 45 reduces the difficulty of forming the bridge pipe 30. In this embodiment, the plugging port 31 is provided at one end of the bridge pipe 30 close to the first water supply pipe 20. In other embodiments, the plugging port 31 may also be provided at one end of the bridge pipe 30 close to the second water supply pipe 60.

[0069] See also Figure 2 , Figure 5 and Figure 8The waterway plate structure 100 further includes a wastewater pipeline 70 and a water pump 46. The wastewater pipeline 70 is at least used to communicate with the first tank 300 to discharge the wastewater in the first tank 300. The water pump 46 is connected to the wastewater pipeline 70 to provide power for the flow of water in the wastewater pipeline 70. The wastewater pipeline 70 and the water pump 46 both extend along the first direction X, and the water outlet end of the wastewater pipeline 70 is formed at the first end 100a of the waterway plate structure 100. In a specific application, when hot water is transported into the first tank 300 for disinfection, the used hot water can be discharged through the wastewater pipeline 70.

[0070] See also Figure 5 , the water circuit board structure 100 also includes a return pipe 80, which is used to connect the water end and the waste water pipe 70, so that the water flow from the water end can flow into the waste water pipe 70 through the return pipe 80. In the related art, when changing from one water supply mode to another water supply mode, since a certain amount of water in the previous water supply mode is stored in the pipe at the water end, it is necessary to release this part of the water from the water end before the water of the changed water supply mode is supplied. For example, when changing from the hot water supply mode (the water outlet pipe 10 delivers hot water to the water end) to the normal temperature water supply mode (the water outlet pipe 10 delivers normal temperature water to the water end), since a certain amount of hot water is stored in the pipe at the water end, it is necessary to release this part of the hot water from the water end before the normal temperature water is supplied, which brings a bad user experience. By setting the return pipe 80 and the waste water pipe 70, when the water supply mode is changed, the water in the previous water supply mode can be returned to the return pipe 80 and then discharged through the waste water pipe 70, and there is no need to discharge the water in the previous water supply mode from the water-using end, which greatly improves the user experience. The return pipe 80 extends along the first direction X, and the part of the return pipe 80 used to connect to the water-using end (i.e., the water inlet end of the return pipe 80) is formed at the first end 100a of the waterway plate structure 100.

[0071] See also Figure 4 and Figure 5 The waterway plate also includes an exhaust pipe 90, which is used to connect to the second tank 400 to discharge the steam in the second tank 400. Since the heat exchange medium (water) in the second tank 400 will generate steam, when the steam reaches a certain level, the air pressure in the second tank 400 increases, which is potentially dangerous. By setting the exhaust pipe 90 to discharge the steam in the second tank 400, the safety of the second tank 400 is improved. Specifically, the second tank 400 is also provided with an exhaust port 404, and the exhaust pipe 90 is connected to the exhaust port 404 so that the steam in the second tank 400 enters the exhaust pipe 90 through the exhaust port 404. Among them, at least a portion of the exhaust pipe 90 extends along the first direction X, and the exhaust end of the exhaust pipe 90 is formed at the first end 100a of the waterway plate structure 100.

[0072] The waterway plate structure 100 also has a third end 100c and a fourth end 100d arranged opposite to each other along the second direction Y. The water inlet pipe 50, the water outlet pipe 10, the return pipe 80, the waste water pipe 70 and the exhaust pipe 90 are arranged adjacent to each other in sequence from the third end 100c to the fourth end 100d along the second direction Y.

[0073] In this embodiment, the water outlet pipeline 10, the first water supply pipeline 20, the bridge pipeline 30, the second water supply pipeline 60, the water inlet pipeline 50, the wastewater pipeline 70, the return pipeline 80 and the exhaust pipeline 90 are all integrated into the waterway plate structure 100, which improves the integration of the waterway plate structure 100, can reduce the occupied space of the water supply device, and is conducive to the miniaturization of the water supply device.

[0074] 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.

[0075] See also Figure 1 and Figure 3 The water supply device also includes a heater 500, which is arranged downstream of the water treatment device 200 and is used to heat the drinking water from the water treatment device 200. Specifically, the water inlet end of the heater 500 is connected to the first outlet 202 of the water treatment device 200, and the water outlet end of the heater 500 is connected to the water outlet pipeline 10. By arranging the water treatment device 200 and the heater 500 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 outlet is "fresh" hot water. It can be understood that in other embodiments, the water supply device may not be provided with a heater 500.

[0076] When the water circuit plate structure 100 is used to provide hot water to the water-using end, the first valve body 41 and the fourth valve body 44 are controlled to be open, and the second valve body 42 and the third valve body 43 are closed. Normal temperature water flows to the water treatment device 200 and the heater 500 through the water inlet pipe 50. After hot water is generated, it flows to the water-using end through the water outlet pipe 10.

[0077] When the water circuit plate structure 100 is used to provide hot water for the first tank 300 and the second tank 400, the second valve body 42 and the fourth valve body 44 are controlled to be opened, and the first valve body 41 and the third valve body 43 are closed. Normal temperature water flows to the water treatment device 200 and the heater 500 through the water inlet pipe 50. After the hot water is generated, it is transported to the bridge pipe 30 through the water outlet pipe 10, and then the first tank 300 is replenished with water through the first water replenishment pipe 20. When the first tank 300 is filled with water or the first tank 300 is replenished with water to a preset water level, the water flows along the second water replenishment pipe 60 to replenish the second tank 400 with water.

[0078] When the waterway plate structure 100 is used to provide normal temperature water to the water-using end, the first valve body 41 and the third valve body 43 are controlled to be open, and the second valve body 42 and the fourth valve body 44 are closed, and the normal temperature water flows into the water inlet pipe 50, then flows into the water outlet pipe 10, and then flows to the water-using end.

[0079] When the water circuit plate structure 100 is used to provide normal temperature water for water-requiring components, the second valve body 42 and the third valve body 43 are controlled to be open, and the first valve body 41 and the fourth valve body 44 are closed, and normal temperature water flows into the water inlet pipe 50, and then flows into the water outlet pipe 10, and flows into the first water replenishment pipe 20 through the bridge pipe 30 to replenish the first tank 300 with water. When the first tank 300 is filled with water or the first tank 300 is replenished with water to a preset water level, the water flows through the bridge pipe 30 into the second water replenishment pipe 60 to replenish the second tank 400 with water.
