[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] In the existing waterway plate processing technology of water supply devices, complex processing methods are usually used to form internal flow channels. These methods not only increase production costs, but also often require cumbersome assembly operations on the waterway plate during the actual assembly process to ensure the formation of the corresponding waterway flow channel structure. The entire processing cycle is long and the production efficiency is low. Moreover, the structure of the waterway plate is not compact and occupies a large space, which is not conducive to the miniaturization of the water supply device.

[0039] 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 sealing component is arranged to cooperate with the sealing port of the waterway plate, so that the waterway plate can be formed in one go during injection molding, thereby reducing the complexity of the production process; and at least two water flow channels are arranged along the thickness direction of the waterway plate, so that the space of the waterway plate in the thickness direction is fully utilized, the integration of the waterway plate is improved, the space occupied by the waterway plate is reduced, and it is conducive to the miniaturization development of the water supply device.

[0040] See also Figures 1 to 3 The embodiment of the present invention provides a waterway plate structure 100, including a waterway plate 101, wherein the waterway plate 101 is provided with a plurality of water flow channels (not shown in the figure), and at least two water flow channels are arranged along the thickness direction of the waterway plate 101. By arranging at least two water flow channels along the thickness direction of the waterway plate 101, the waterway channels can be arranged by utilizing the space of the waterway plate 101 in the thickness direction, thereby improving the integration of the waterway plate 101, reducing its occupied space, and facilitating the miniaturization development of the water supply device.

[0041] See also Figure 1 and Figure 3 The waterway plate structure 100 further includes a plugging component 102, at least one water channel is provided with a plugging port, the plugging port is opened on the outside of the waterway plate 101, and the part of the water channel close to the plugging port extends along the axial direction of the plugging port; the plugging component 102 is connected to the waterway plate 101 and seals the plugging port. By arranging the plugging component 102 to cooperate with the plugging port of the waterway plate 101, the waterway plate 101 can be formed in one go during injection molding, reducing the complexity of the production process.

[0042] The traditional waterway plate 101 needs to go through a complicated processing flow to form a water flow channel in the waterway plate 101. The waterway plate structure 100 of this embodiment, by setting a sealing port connected to the water flow channel on the outer side of the waterway plate 101, can be directly demolded along the axial direction of the sealing port during the injection molding process. During the assembly process, the sealing port is sealed by the sealing component 102 to form a preset water flow channel. The processing difficulty of the waterway plate 101 is reduced, the production efficiency is improved, and the cost is reduced.

[0043] See also Figures 1 to 3 , Figure 5 and Figure 6 The multiple water flow channels include a water outlet pipe 10 and a water replenishment pipe 20 connected to the water outlet pipe 10, and at least part of the water replenishment pipe 20 is arranged below the water outlet pipe 10 along the thickness direction of the waterway plate 101. One end of the water outlet pipe 10 is used to connect to the water-using end (such as a faucet), and the other end of the water outlet pipe 10 is used to connect to the drinking water outlet 201 of the heat exchange device 200, and the water replenishment pipe 20 is used to replenish water for the water-demanding equipment 300. The water outlet pipe 10 and the water replenishment pipe 20 are arranged on the waterway plate 101, so that the water flow channel of the waterway plate 101 can not only transport water to the water-using end, but also replenish water for the water-demanding equipment 300. Among them, the water outlet pipe 10 can transport hot water to the water-using end and the water replenishment pipe 20. By arranging at least part of the water replenishment pipeline 20 below the water outlet pipeline 10 along the thickness direction of the waterway plate 101, the water outlet pipeline 10 and the water replenishment pipeline 20 can be arranged using the space in the thickness direction of the waterway plate 101, thereby improving the integration of the waterway plate 101 and reducing the space occupied by the waterway plate 101.

[0044] See also Figure 2 , Figure 3 and Figure 5 The water replenishment pipeline 20 includes a first water replenishment branch 21, a second water replenishment branch 22 and a first bridge pipe 23. The first bridge pipe 23 is arranged below the water outlet pipeline 10 along the thickness direction of the waterway plate 101, and connects the water outlet pipeline 10 and the first water replenishment branch 21, and connects the water outlet pipeline 10 and the second water replenishment branch 22. The first water replenishment branch 21 is used to connect the first tank 301 to replenish water for the first tank 301, and the second water replenishment branch 22 is used to connect the second tank (not marked in the figure) to replenish water for the second tank. The first tank 301 and the second tank are both water-demanding equipment 300. Among them, the first tank 301 can be a hot tank, and the second tank can be an ice tank.

[0045] Specifically, a heat exchange medium (hot water) is provided in the first tank 301, and the heat exchange medium can perform heat exchange with drinking water to increase the temperature of the drinking water. Before the heat exchange medium performs heat exchange, steam is easily formed due to the high temperature, so the heat exchange medium in the first tank 301 will decrease, and it is necessary to replenish water regularly or irregularly. The second tank is a cooling device that can cool the water flowing through it. The second tank is used to connect to the water end to provide cooled drinking water for the water end, so the water in the second tank will often decrease, and it is necessary to replenish water frequently. In this embodiment, by setting a first water replenishment branch 21 and a second water replenishment branch 22, water replenishment for the first tank 301 and the second tank is achieved. By setting a first bridging pipe 23, the connection between the water outlet pipe 10 and the first water replenishment branch 21 and the second water replenishment branch 22 is achieved.

[0046] See also Figure 1 and Figure 3 The first bridge pipe 23 is also provided with a first blocking port 231. The blocking assembly 102 includes a first blocking member 1021, and the first blocking member 1021 is used to seal the first blocking port 231. The first blocking port 231 is provided to facilitate injection molding of the first bridge pipe 23. The first blocking member 1021 is provided to seal the first blocking port 231 to prevent water from flowing out of the first blocking port 231. The cooperation between the first blocking port 231 and the first blocking member 1021 reduces the difficulty of forming the first bridge pipe 23.

[0047] See also Figure 2 , Figure 5 and Figure 6 The multiple water flow channels also include a water inlet pipe 30, one end of which is used to connect to a water source, and the other end of which is used to connect to a drinking water inlet 202 of the heat exchange device 200. In this way, the water inlet pipe 30 can deliver drinking water to the heat exchange device 200. By arranging the water inlet pipe 30 on the waterway plate 101, the integration of the waterway plate structure 100 is further improved, which is conducive to reducing the volume of the water supply device. The water source can be purified water filtered by an RO filter element.

[0048] In one embodiment, the water inlet pipeline 30 and the water outlet pipeline 10 are arranged side by side. In this way, the regularity of the arrangement of the water inlet pipeline 30 and the water outlet pipeline 10 can be improved, which facilitates the arrangement of other pipelines on the waterway plate 101, further improves the integration of the waterway plate 101, and helps to reduce the occupied space of the water supply device. Of course, in other embodiments, the water outlet pipeline 10 and the water inlet pipeline 30 can also be arranged in other ways.

[0049] See also Figure 2The waterway plate structure 100 further includes a flow meter 103, which is disposed on a side of the water inlet pipe 30 close to the water outlet pipe 10. The flow meter 103 can be used to detect the flow rate of water flow. The flow meter 103 is disposed on a side of the water inlet pipe 30 close to the water outlet pipe 10. Compared with the technical solution in which the flow meter 103 is disposed on a side of the water inlet pipe 30 far from the water outlet pipe 10, the space between the waterway plate 101 and the water inlet pipe 30 and the water outlet pipe 10 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.

[0050] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 The plurality of water flow channels also include a second bridge pipe 40, which is connected between the water inlet pipe 30 and the flow meter 103, and the water outlet of the flow meter 103 is used to connect the drinking water inlet 202 of the heat exchange device 200. By setting the second bridge pipe 40 to connect the water inlet pipe 30 and the flow meter 103, the second bridge pipe 40 can be designed according to the setting position of the flow meter 103, thereby increasing the flexibility of setting the flow meter 103, so that after the flow meter 103 is connected to the water inlet pipe 30 and the heat exchange device 200, the distance between the heat exchange device 200 and the waterway plate 101 can be reduced, thereby reducing the occupied volume of the water supply device, which is conducive to the miniaturization of the water purification and supply device. In addition, by increasing the flexibility of setting the flow meter 103, the flexibility of setting the heat exchange device 200 is also improved.

[0051] In one embodiment, the second bridge pipe 40 is arranged below the water inlet pipe 30 along the thickness direction of the waterway plate 101. In this way, the second bridge pipe 40 can be arranged using the space in the thickness direction of the waterway plate 101, thereby improving the integration of the waterway plate 101 and reducing the space occupied by the waterway plate 101.

[0052] In one embodiment, the flow meter 103 is arranged in parallel with the water inlet pipeline 30, and the second bridge pipe 40 is arranged perpendicular to the water inlet pipeline 30. In this way, the arrangement of the water inlet pipeline 30, the flow meter 103 and the second bridge pipe 40 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 30, the flow meter 103 and the second bridge pipe 40 can also be arranged in other ways.

[0053] See also Figure 1 and Figure 3The second bridge pipe 40 is also provided with a second plugging port 41, and the plugging assembly 102 further includes a second plugging member 1022, and the second plugging member 1022 is used to seal the second plugging port 41. The second plugging port 41 is provided to facilitate injection molding of the second bridge pipe 40. The second plugging port 41 is sealed by providing the second plugging member 1022 to prevent water from flowing out of the second plugging port 41. The cooperation between the second plugging port 41 and the second plugging member 1022 reduces the difficulty of forming the second bridge pipe 40.

[0054] See also Figure 2 and Figure 3 The plurality of water flow channels further include a third bridge pipe 50, which extends in the thickness direction of the waterway plate 101 and is used to connect the water outlet pipe 10 and the water inlet pipe 30. By providing the third bridge pipe 50, the water inlet pipe 30 can transport normal temperature water to the water outlet pipe 10, and then the water outlet pipe 10 can transport normal temperature water to the water use end and the water supply pipe 20. In addition, the third bridge pipe 50 is extended in the thickness direction of the waterway plate 101, which can reduce the spacing between the water inlet pipe 30 and the water outlet pipe 10, and make full use of the space of the waterway plate 101 in the thickness direction, thereby improving the integration of the waterway plate 101.

[0055] See also Figure 1 and Figure 3 The third bridge pipe 50 is provided with a third plugging port 521, and the plugging assembly 102 further includes a third plugging member 1023, and the third plugging member 1023 is used to seal the third plugging port 521. Specifically, the third bridge pipe 50 includes a first bridge branch pipe 51 connected to the water inlet pipe 30 and a second bridge branch pipe 52 connected to the water outlet pipe 10, and the first bridge branch pipe 51 and the second bridge branch pipe 52 both extend along the thickness direction of the waterway plate 101, and partially overlap to communicate with each other. Among them, the second bridge branch pipe 52 is provided with a third plugging port 521.

[0056] The third plugging port 521 is provided to facilitate injection molding of the second bridging branch pipe 52. The third plugging member 1023 is provided to seal the third plugging port 521 to prevent water from flowing out of the third plugging port 521. The cooperation between the third plugging port 521 and the third plugging member 1023 reduces the difficulty of forming the second bridging branch pipe 52.

[0057] See also Figure 2 The multiple water flow channels also include a return pipe 60 and a waste water pipe 70. One end of the return pipe 60 is used to connect to the water end, and the other end of the return pipe 60 is used to connect to the waste water pipe 70. The waste water pipe 70 is at least used to discharge the waste water from the return pipe 60.

[0058] When the water supply device is changed 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 pipeline at the water-using end, it is necessary to release this part of the water from the water-using end before the water in the changed water supply mode can be supplied. For example, when the hot water supply mode (the water outlet pipeline 10 delivers hot water to the water-using end) is changed to the normal temperature water supply mode (the water outlet pipeline 10 delivers normal temperature water to the water-using end), since a certain amount of hot water is stored in the pipeline at the water-using end, it is necessary to release this part of the hot water from the water-using end before the normal temperature water can be supplied, which brings a bad user experience. By setting the reflux pipeline 60 and the wastewater pipeline 70, when the water supply mode is changed, the water in the previous water supply mode can be refluxed into the reflux pipeline 60, and then discharged through the wastewater pipeline 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's user experience.

[0059] In this embodiment, by providing the return pipe 60 and the waste water pipe 70 on the waterway plate 101 , the integration of the waterway plate 101 is improved, which is beneficial to reducing the occupied space of the water supply device.

[0060] See also Figure 2 and Figure 5 The plurality of water flow channels further include an exhaust pipe 80, which is used to connect to the first tank 301 to discharge the steam from the first tank 301. Since the heat exchange medium (hot water) in the first tank 301 will generate steam, when the steam reaches a certain level, the air pressure in the first tank 301 increases, which is potentially dangerous. By setting the exhaust pipe 80 to discharge the steam in the first tank 301, the safety of the first tank 301 is improved. By setting the exhaust pipe 80 in the waterway plate 101, the integration of the waterway plate 101 is improved, which is conducive to reducing the occupied space of the water supply device.

[0061] In one embodiment, the return pipe 60, the waste water pipe 70 and the exhaust pipe 80 are arranged side by side with the outlet pipe 10, so that the regularity of the arrangement of the return pipe 60, the waste water pipe 70, the exhaust pipe 80 and the outlet pipe 10 can be improved, and it is convenient for other pipes to be arranged on the waterway plate 101, further improving the integration of the waterway plate 101, which is conducive to reducing the occupied space of the water supply device. Of course, in other embodiments, the return pipe 60, the waste water pipe 70 and the exhaust pipe 80 can also be arranged in other ways.

[0062] In one embodiment, the waterway plate 101 is an integrally formed structure, so that the connection sealing performance between the water flow channels can be improved to prevent water leakage in the water flow channels.

[0063] See also Figure 4 and Figure 5The embodiment of the present invention further provides a water supply device, including the waterway plate structure 100. By adopting the waterway plate structure 100, the production efficiency of the water supply device can be increased, the production cost of the water supply device can be reduced, and the occupied space of the water supply device can be reduced, which is conducive to the miniaturization of the water supply device.

[0064] See also Figure 5 The water supply device also includes a first tank 301 and a heat exchange device 200. The first tank 301 is provided with a heat exchange medium (hot water). The first tank 301 is connected to the heat exchange device 200. The heat exchange medium can flow into the heat exchange device 200, exchange heat with the drinking water in the heat exchange device 200, and then flow back into the first tank 301.

[0065] The heat exchange device 200 is provided with a drinking water channel (not shown), a drinking water inlet 202, a drinking water outlet 201, a medium channel (not shown), a medium inlet 203 and a medium outlet 204. The drinking water channel and the medium channel are adjacent and isolated. The drinking water inlet 202 and the drinking water outlet 201 are connected to the drinking water channel respectively, and the medium inlet 203 and the medium outlet 204 are connected to the medium channel respectively. 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 first tank 301 is connected to the medium channel. The heat exchange medium in the first 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 hot water tank. In this embodiment, the drinking water outlet 201 of the heat exchange device 200 is connected to the water outlet pipeline 10, and the drinking water inlet 202 of the heat exchange device 200 is connected to the flowmeter 103, and then connected to the water inlet pipeline 30.

[0066] See also Figure 1 , Figure 5 and Figure 6 The water supply device further includes a heating device 400, which is disposed downstream of the heat exchange device 200 and is used to heat the drinking water from the heat exchange device 200. Specifically, the water inlet end of the heating device 400 is connected to the drinking water outlet 201 of the heat exchange device 200, and the water outlet end of the heating device 400 is connected to the water outlet pipeline 10. By arranging the heat exchange device 200 and the heating device 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 the heating device 400.

[0067] See also Figure 4 and Figure 5 The water supply device also includes a shell 500, the waterway plate structure 100, the heat exchange device 200, the first tank 301 and the heating device 400 are all arranged in the shell 500, and the water supply device as a whole is a rectangular parallelepiped.
