[0031] 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

[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 technical features indicated. 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 considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention. It should be noted that in this embodiment, the first direction Z refers to the height direction of the waterway plate, the second direction Y refers to the width direction of the waterway plate, and the third direction X refers to the length direction of the waterway plate. The dotted line in the accompanying drawing indicates the flow direction of water in the pipeline.

[0036] The water supply device can filter water and heat water, and is popular among people. However, in the related art, due to the size limitation of the waterway plate and the connection limitation of the flow meter and the water treatment device, the overall volume of the water supply device is too large, which is not conducive to its miniaturization and limits its widespread use.

[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 and a water treatment device. The water treatment device is used to generate hot water from drinking water flowing through the waterway plate structure. The waterway plate structure connects the water inlet pipeline and the flow meter by setting a bridge pipe, thereby improving the flexibility of connecting the flow meter and the water inlet pipeline, thereby reducing the distance between the water treatment device and the waterway plate after being connected to the flow meter. This is beneficial to reducing the space occupied by the water supply device and contributing to the miniaturization of the water supply device.

[0038] See also Figures 1 to 8 The water supply device provided in the embodiment of the present invention includes a water treatment device 200 and a waterway plate structure 100. 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 located in the water treatment device 200 to exchange heat so that the drinking water flowing through generates hot water.

[0039] The waterway plate structure 100 includes a waterway plate 10 and a flow meter 20, and the flow meter 20 is arranged on the waterway plate 10. The water treatment device 200 is provided with a first input port 201 and a first output port 202, the first input port 201 is used for supplying drinking water into the water treatment device 200, and the first output port 202 is used for supplying drinking water in the water treatment device 200 to flow out of the water treatment device 200, and the water outlet of the flow meter 20 is connected to the first input port 201.

[0040] When in use, drinking water flows from the flow meter 20 to the water treatment device 200 , flows into the water treatment device 200 through the first input port 201 , and after hot water is generated, flows out of the water treatment device 200 through the first output port 202 .

[0041] See also Figure 6 and Figure 7 The waterway plate 10 includes a water inlet pipeline 11 and a first bridge pipe 12. The flow meter 20 is arranged beside the water inlet pipeline 11. The first bridge pipe 12 intersects with the water inlet pipeline 11 and connects the water inlet of the flow meter 20 and the water inlet pipeline 11. The water outlet of the flow meter 20 is connected to the first input port 201 of the water treatment device 200. The water inlet pipeline 11 is used to connect to the water source. In specific implementation, drinking water flows through the water inlet pipeline 11, the first bridge pipe 12 and the flow meter 20 in sequence, and then flows into the water treatment device 200.

[0042] As an embodiment, drinking water includes but is not limited to purified water filtered through a reverse osmosis filter.

[0043] By setting the first bridge pipe 12 on the waterway plate 10 to connect the water inlet pipe 11 and the flow meter 20, the setting of the first bridge pipe 12 is relatively flexible, thereby increasing the flexibility of setting the flow meter 20, so that after the flow meter 20 is connected to the waterway plate 10 and the water treatment device 200, the distance between the water treatment device 200 and the waterway plate 10 can be reduced, thereby reducing the occupied volume of the water supply device, which is conducive to the miniaturization of the water supply device. In addition, by increasing the flexibility of setting the flow meter 20, the flexibility of setting the water treatment device 200 is also improved.

[0044] In one embodiment, the flow meter 20 is arranged in parallel with the water inlet pipeline 11, and the first bridge pipe 12 extends in a direction perpendicular to the water inlet pipeline 11. In this way, the arrangement of the water inlet pipeline 11, the flow meter 20 and the first bridge pipe 12 is relatively regular, which is conducive to the arrangement of other components of the waterway plate structure 100, improves the integration of the waterway plate structure 100, and further reduces the occupied volume of the waterway plate structure 100. Of course, in other embodiments, the water inlet pipeline 11, the flow meter 20 and the first bridge pipe 12 can also be arranged in other ways.

[0045] In one embodiment, the first bridge pipe 12 includes a bridge branch or at least two bridge branches. The bridge branch connected to the flow meter 20 extends along the first direction Z, that is, extends along the thickness direction of the waterway plate structure 100, and the water inlet of the flow meter 20 extends into the bridge branch. Since the water inlet of the flow meter 20 is not large, when a water guide port is set on the side wall of the pipeline to connect the flow meter 20, a passage with sufficient water flow area cannot usually be generated. Even if a passage is generated, it will cause excessive space occupation. Extending the bridge branch connected to the flow meter 20 along the thickness direction of the waterway plate structure 100 can make the water inlet of the flow meter 20 extend from one end of the bridge branch into the bridge branch. In this way, the connected passage not only has a sufficient water flow area, but also increases the integration of the flow meter 20 and the bridge branch, reducing the occupied space.

[0046] See also Figure 6 In this embodiment, the first bridge pipe 12 includes two bridge branches, which are defined as a first bridge branch 121 and a second bridge branch 122. The first bridge branch 121 is connected to the flow meter 20, and the second bridge branch 122 is connected between the water inlet pipe 11 and the first bridge branch 121. The water inlet of the flow meter 20 extends into the first bridge branch 121.

[0047] In one embodiment, the second bridging branch 122 extends along the second direction Y, that is, the second bridging branch 122 extends along the width direction of the waterway plate structure 100. A first blocking opening 123 is provided at one end of the second bridging branch 122 away from the first bridging branch 121, and the waterway plate structure 100 further includes a first blocking member (not shown), which is used to seal the first blocking opening 123.

[0048] By providing the first blocking port 123 in the second bridging branch 122, it is convenient to injection mold the second bridging branch 122. By providing the first blocking member to seal the first blocking port 123, water is prevented from flowing out of the first blocking port 123. The cooperation between the first blocking port 123 and the first blocking member reduces the difficulty of forming the second bridging branch 122. It can be understood that in other implementations, the second bridging branch 122 can also extend along the first direction Z.

[0049] In one embodiment, the second bridging branch 122 is located below the water inlet pipe 11. In this way, the space of the waterway plate 10 in the thickness direction can be used to improve the integration of the waterway plate 10.

[0050] See also Figure 7 The waterway plate 10 further includes a water outlet pipe 13, which is used to connect at least the first output port 202 of the water treatment device 200 and a water-using end (e.g., a faucet). In this way, the heated drinking water flowing out of the water treatment device 200 can be delivered to the water-using end through the water outlet pipe 13.

[0051] In one embodiment, the water outlet pipe 13 and the water inlet pipe 11 are arranged side by side, and both extend along the third direction X, that is, along the length direction of the waterway plate structure 100. In this way, the arrangement of the water outlet pipe 13 and the water inlet pipe 11 is relatively regular, which is conducive to the arrangement of other components of the waterway plate structure 100, improves the integration of the waterway plate structure 100, and further reduces the occupied volume of the waterway plate structure 100. Of course, in other embodiments, the water outlet pipe 13 and the water inlet pipe 11 can also be arranged in other ways.

[0052] In one embodiment, the flow meter 20 is arranged between the water inlet pipe 11 and the water outlet pipe 13, that is, the flow meter 20 is arranged on the side of the water inlet pipe 11 close to the water outlet pipe 13. Compared with the technical solution in which the flow meter 20 is arranged on the side of the water inlet pipe 11 away from the water outlet pipe 13, the space of the waterway plate 10 between the water inlet pipe 11 and the water outlet pipe 13 is fully utilized, the integration of the waterway plate structure 100 is improved, and it is beneficial to reduce the occupied volume of the waterway plate structure 100.

[0053] See also Figure 6 The waterway plate 10 further includes a second bridge pipe 14, which is used to connect the water inlet pipe 11 and the water outlet pipe 13. In this way, the water outlet pipe 13 can transport the normal temperature water of the water inlet pipe 11 to the water-using end. Therefore, the water outlet pipe 13 can not only transport hot water to the water-using end, but also transport normal temperature water to the water-using end.

[0054] The water inlet pipe 11 includes a first end 111 and a second end 112 that are arranged opposite to each other. The first end 111 is used to connect to a water source, and the second end 112 is used to connect to the first bridge pipe 12. The second bridge pipe 14 is connected between the first end 111 and the second end 112. The first bridge pipe 12 is connected to the end of the water inlet pipe 11, so that the flow meter 20 can be installed at a position away from the center of the waterway plate 10, thereby improving the convenience of connecting the flow meter 20 to the water treatment device 200. It can be understood that in other embodiments, the second end 112 can also be connected to the second bridge pipe 14, and the first bridge pipe 12 can also be connected between the first end 111 and the second end 112.

[0055] See also 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 inlet pipeline 11 and the first bridge pipeline 12, and the second control valve 32 is used to control the connection or disconnection between the water inlet pipeline 11 and the second bridge pipeline 14.

[0056] In specific implementation, when the first control valve 31 is opened and the second control valve 32 is closed, the water inlet pipeline 11 is connected to the first bridge pipe pipeline 12 and is disconnected from the second bridge pipe pipeline 14, and drinking water flows through the water inlet pipeline 11, the first bridge pipe pipeline 12, the flow meter 20, the water treatment device 200 and the water outlet pipeline 13 in sequence, so that the water outlet pipeline 13 provides hot water to the water user end; when the first control valve 31 is closed and the second control valve 32 is opened, the water inlet pipeline 11 is connected to the second bridge pipe pipeline 14 and is disconnected from the first bridge pipe pipeline 12, and drinking water flows through the water inlet pipeline 11, the second bridge pipe pipeline 14 and the water outlet pipeline 13 in sequence, so that the water outlet pipeline 13 provides normal temperature water to the water user end.

[0057] In one embodiment, the first control valve 31 and the second control valve 32 are both disposed above the water inlet pipe 11, the water outlet pipe 13 and the flow meter 20, and the first bridge pipe 12 and the second bridge pipe 14 are both disposed below the water inlet pipe 11, the water outlet pipe 13 and the flow meter 20. This arrangement improves the integration of the waterway plate structure 100 and helps reduce the occupied space of the waterway plate structure 100.

[0058] In one embodiment, the first control valve 31 and the second control valve 32 are both solenoid valves.

[0059] The water outlet pipe 13 includes a third end 131 and a fourth end 132 which are arranged opposite to each other. The third end 131 is used to connect to the water use end, and the fourth end 132 is used to connect to the first output port 202 of the water treatment device 200. The second bridge pipe 14 is connected between the third end 131 and the fourth end 132.

[0060] In a specific implementation, water flows into the water outlet pipe 13 from the fourth end 132 of the water outlet pipe 13, and then flows out of the water outlet pipe 13 from the third end 131 of the water outlet pipe 13. The fourth end 132 is connected to the first output port 202 of the water treatment device 200, so that hot water can flow through the entire water outlet pipe 13, thereby sterilizing the entire water outlet pipe 13. Of course, in other embodiments, the second bridge pipe 14 can also be connected to the fourth end 132, and the first output port 202 of the water treatment device 200 can also be connected between the third end 131 and the fourth end 132.

[0061] In one embodiment, the waterway plate structure 100 further includes a one-way valve 40, which is connected to the second bridge pipe 14 and is used to allow water to flow from the water inlet pipe 11 to the water outlet pipe 13 in one direction. Since the second bridge pipe 14 is connected between the third end 131 and the fourth end 132, when hot water is output through the first output port 202 of the water treatment device 200 and flows into the water outlet pipe 13 from the fourth end 132 of the water outlet pipe 13, it will pass through the connection between the second bridge pipe 14 and the water outlet pipe 13, and thus may flow to the water inlet pipe 11. By providing the one-way valve 40, hot water can be prevented from flowing to the water inlet pipe 11 through the second bridge pipe 14.

[0062] In one embodiment, the first end 111 of the water inlet pipe 11 and the third end 131 of the water outlet pipe 13 are disposed correspondingly and are located on the same side of the waterway plate structure 100. Figure 7 As shown, the first end 111 of the water inlet pipe 11 and the third end 131 of the water outlet pipe 13 are both located on the left side of the waterway plate structure 100. In this way, the regularity of the arrangement of the water inlet pipe 11 and the water outlet pipe 13 is improved.

[0063] See also Figure 3 The water supply device further includes a heat storage container 300, in which a heat exchange medium is arranged, and the heat storage container 300 is connected with the water treatment device 200, and the heat exchange medium can flow into the water treatment device 200, and after heat exchange with the drinking water in the water treatment device 200, flow back into the heat storage container 300. The heat exchange medium and the drinking water flow along two isolated channels in the water treatment device 200 respectively.

[0064] See also Figure 4 , Figure 7 and Figure 8The water treatment device 200 is also provided with a second input port 203 and a second output port 204, the heat storage container 300 is provided with a discharge port 301 and a return port 302, and the waterway plate 10 further includes a heat exchange medium output pipeline 15 and a heat exchange medium return pipeline 16. The heat exchange medium output pipeline 15 is used to connect the discharge port 301 of the heat storage container 300 and the second input port 203 of the water treatment device 200, and the heat exchange medium return pipeline 16 is used to connect the return port 302 of the heat storage container 300 and the second output port 204 of the water treatment device 200.

[0065] In specific implementation, the heat exchange medium flows into the heat exchange medium output pipeline 15 through the discharge port 301 of the heat storage container 300, and then flows into the water treatment device 200 through the second input port 203 of the water treatment device 200. After heat exchange with drinking water in the water treatment device 200, the heat exchange medium flows into the heat exchange medium return pipeline 16 from the second output port 204 of the water treatment device 200, and then flows back into the heat storage container 300 through the return port 302 of the heat storage container 300.

[0066] The waterway plate structure 100 further includes a pump body 50, which is connected to the heat exchange medium output pipeline 15 to provide power for the heat exchange medium to flow between the heat storage container 300 and the water treatment device 200. It is understood that in other embodiments, the pump body 50 may also be connected to the heat exchange medium return pipeline 16. In a specific application, when hot water needs to be output, the pump body 50 may be started to allow the heat exchange medium to flow between the heat storage container 300 and the water treatment device 200, so that the heat exchange medium can exchange heat with the drinking water in the water treatment device 200 when flowing through the water treatment device 200.

[0067] In one embodiment, the flow meter 20, the heat exchange medium output pipeline 15 and the heat exchange medium return pipeline 16 are correspondingly arranged and located on the same side of the waterway plate structure 100. Figure 7 As shown, the flow meter 20, the heat exchange medium output pipeline 15 and the heat exchange medium return pipeline 16 are all located on the right side of the waterway plate structure 100. This arrangement improves the regularity of the waterway plate structure 100 on the one hand, and facilitates the connection of the flow meter 20, the heat exchange medium output pipeline 15 and the heat exchange medium return pipeline 16 with the water treatment device 200 on the other hand.

[0068] In one embodiment, the heat exchange medium includes but is not limited to water and thermal oil.

[0069] See also Figure 6 The waterway plate 10 further includes a water supply pipeline 17, and the water supply pipeline 17 is at least used to supply water to the heat storage container 300. When this technical solution is adopted, the heat exchange medium in the heat storage container 300 is water.

[0070] The water supply pipeline 17 can be connected to the water inlet pipeline 11 and the heat storage container 300, or can be connected to the water outlet pipeline 13 and the heat storage container 300. When the water supply pipeline 17 is connected to the water inlet pipeline 11 and the heat storage container 300, the water flow in the water inlet pipeline 11 can be used to replenish the heat storage container 300; when the water supply pipeline 17 is connected to the water outlet pipeline 13 and the heat storage container 300, the water flow in the water outlet pipeline 13 can be used to replenish the heat storage container 300. Preferably, the water supply pipeline 17 is connected to the water outlet pipeline 13 and the heat storage container 300, so that the heat storage container 300 can be replenished with both normal temperature water and hot water.

[0071] In one embodiment, the water supply device further includes a cooling container (not shown), which is used to cool the drinking water. The water supply pipeline 17 is also used to replenish water for the cooling container. Of course, in other embodiments, the water supply device may not be provided with a cooling container.

[0072] See also Figure 3 and Figure 6 The water replenishment pipeline 17 includes a first water replenishment branch 171, a second water replenishment branch 172 and a third bridge pipe 173. The first water replenishment branch 171 is connected to the heat storage container 300 for replenishing water for the heat storage container 300. The second water replenishment branch 172 is connected to the cooling container for replenishing water for the cooling container. The third bridge pipe 173 connects the water outlet pipeline 13 and the first water replenishment branch 171, and connects the water outlet pipeline 13 and the second water replenishment branch 172.

[0073] The third bridge pipe 173 is located below the water outlet pipe 13 and extends along the second direction Y. The third bridge pipe 173 is provided with a second plugging port 1731. The waterway plate structure 100 also includes a second plugging member (not shown in the figure), which is used to seal the second plugging port 1731. Providing the second plugging port 1731 on the third bridge pipe 173 is conducive to injection molding the third bridge pipe 173. The second plugging port 1731 is sealed by providing the second plugging member to prevent water from flowing out of the second plugging port 1731. The cooperation between the second plugging port 1731 and the second plugging member reduces the difficulty of forming the third bridge pipe 173.

[0074] See also Figures 5 to 7 The waterway plate structure 100 also includes a third control valve 33 and a fourth control valve 34. The third control valve 33 is used to control the connection or disconnection between the water outlet pipeline 13 and the water use end, and the fourth control valve 34 is used to control the connection or disconnection between the water outlet pipeline 13 and the water supply pipeline 17. Specifically, the fourth control valve 34 is used to control the connection or disconnection between the water outlet pipeline 13 and the third bridge pipeline 173.

[0075] In specific implementation, when the third control valve 33 is opened and the fourth control valve 34 is closed, the water outlet pipe 13 is connected to the water use end and is disconnected from the third bridge pipe 173, so that the water flow in the water outlet pipe 13 can be delivered to the water use end; when the third control valve 33 is closed and the fourth control valve 34 is opened, the water outlet pipe 13 is connected to the third bridge pipe 173 and is disconnected from the water use end, so that the water flow in the water outlet pipe 13 can be delivered to the third bridge pipe 173.

[0076] In one embodiment, the third control valve 33 and the fourth control valve 34 are both disposed above the water outlet pipe 13. In this way, the integration of the waterway plate structure 100 is increased, which is beneficial to reducing the occupied space of the waterway plate structure 100.

[0077] In one embodiment, the third control valve 33 and the fourth control valve 34 are both solenoid valves.

[0078] See also Figure 3 and Figure 7 The waterway plate 10 further includes an exhaust pipe 18, which is used to communicate with the heat storage container 300 to discharge the steam in the heat storage container 300. Since the heat exchange medium (hot water) in the heat storage container 300 will generate steam, when the steam reaches a certain level, the air pressure in the heat storage container 300 increases, which is potentially dangerous. By arranging the exhaust pipe 18 to discharge the steam in the heat storage container 300, the safety of the heat storage container 300 is improved.

[0079] In one embodiment, the waterway plate 10 is an integrally formed structure, so that the connection sealing between the pipelines can be improved to prevent water leakage in the pipelines.

[0080] See also Figure 3 The water supply device also includes a heater 400, 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 400 is connected to the first output port 202 of the water treatment device 200, and the water outlet end of the heater 400 is connected to the water outlet pipeline 13. By arranging the water treatment device 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 hot water can be achieved. The drinking hot water does not need to be heated and stored in advance, that is, the water output is "fresh" hot water. Of course, in other embodiments, the water supply device may not be provided with a heater 400.

[0081] In one embodiment, the waterway plate structure 100 is disposed above the heat storage container 300, and the water treatment device 200 and the heater 400 are both disposed on one side of the heat storage container 300 and the waterway plate structure 100. The water supply device further includes a housing 500, and the waterway plate structure 100, the water treatment device 200, the heat storage container 300 and the heating chamber are all disposed in the housing 500. The water supply device is in the shape of a rectangular parallelepiped as a whole.

[0082] When the water circuit plate structure 100 is used to provide hot water to 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 normal temperature water flows into the water inlet pipe 11, and then flows to the water treatment device 200 and the heater 400 through the water inlet pipe 11. After hot water is generated, it flows to the water-using end through the water outlet pipe 13.

[0083] When the waterway plate structure 100 is used to provide hot water for the heat storage container 300 and the cooling container, 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 controlled to be closed, and normal temperature water flows into the water inlet pipe 11, and then flows to the water treatment device 200 and the heater 400 through the water inlet pipe 11. After generating hot water, it flows into the water outlet pipe 13, and flows into the second water replenishment branch 172 through the third bridge pipe 173 to replenish water for the cooling container. When the cooling container is filled with water or the cooling container is replenished with water to a preset water level, the water flows through the third bridge pipe 173 into the first water replenishment branch 171 to replenish water for the heat storage container 300.

[0084] When the waterway plate structure 100 is used to provide normal temperature water to the water-using end, 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, and the normal temperature water flows into the water inlet pipe 11, flows into the water outlet pipe 13 through the second bridge pipe 14, and then flows to the water-using end.

[0085] When the waterway plate structure 100 is used to provide normal temperature water for the heat storage container 300 and the cooling container, 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. Normal temperature water flows into the water inlet pipe 11, flows into the water outlet pipe 13 through the second bridge pipe 14, and flows into the second water replenishment branch 172 through the third bridge pipe 173 to replenish water for the cooling container. When the cooling container is filled with water or the cooling container is replenished with water to a preset water level, the water flows through the third bridge pipe 173 into the first water replenishment branch 171 to replenish water for the heat storage container 300.
