In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0047] The water dispenser 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0048] like Figures 1 to 11 As shown, the water dispenser 100 according to the embodiment of the utility model includes: a hot tank assembly 1 and an inlet and outlet waterway plate 2, the hot tank assembly 1 has a heating chamber 111 and a water inlet joint 121 and a first water outlet joint 113 connected to the heating chamber 111, a heating element 112 is provided in the heating chamber 111, the hot tank assembly 1 is connected to the inlet and outlet waterway plate 2 and is located below the inlet and outlet waterway plate 2, a water diversion pool 211 is formed on the upper surface of the inlet and outlet waterway plate 2, a water supply channel (not shown) and a water outlet channel 221 are formed in the inlet and outlet waterway plate 2, a water supply joint 212 and a second water outlet joint 222 are provided on the inlet and outlet waterway plate 2, the water supply joint 212 is connected to the water diversion pool 211 through the water supply channel and is connected to the water inlet joint 121, and the first water outlet joint 113 is connected to the second water outlet joint 222.

[0049] That is, the heating chamber 111 can be connected to the water supply channel through the connection between the water inlet joint 121 and the water supply joint 212, so that the heating chamber 111 can be connected to the water diversion pool 211 through the water supply channel, and the water in the water diversion pool 211 can enter the heating chamber 111 through the water supply channel under the action of its own weight and be heated by the heating element 112 to form hot water. The heating chamber 111 can be connected to the water outlet channel 221 through the connection between the first water outlet joint 113 and the second water outlet joint 222, so that the hot water in the heating chamber 111 can be discharged through the water outlet channel 221 for drinking by the user. Among them, the water distribution pool 211, the water supply channel, i.e., the channel for supplying water to the hot tank assembly 1, and the water outlet channel 221, i.e., the channel for realizing water outlet of the hot tank assembly 1, are all integrated in the water inlet and outlet waterway plate 2, which can well improve the integration of the water inlet and outlet waterway plate 2 to reduce the number of parts of the water dispenser 100, and at the same time, the hot tank assembly 1 only needs to be connected to the water inlet and outlet waterway plate 2 to form a complete hot water output flow path. Therefore, the assembly steps of the water dispenser 100 can be well simplified, which is conducive to improving the assembly efficiency of the water dispenser 100.

[0050] According to the water dispenser 100 of the embodiment of the utility model, the water distribution tank 211, the water supply channel and the water outlet channel 221 are all integrated in the water inlet and outlet waterway plate 2, which can improve the integration of the water inlet and outlet waterway plate 2 to reduce the number of parts of the water dispenser 100. At the same time, the hot tank assembly 1 only needs to be connected to the water inlet and outlet waterway plate 2 to form a complete hot water output flow path, which can greatly simplify the assembly steps of the water dispenser 100 and help improve the assembly efficiency of the water dispenser 100.

[0051] The water supply channel is located below the water distribution pool 211 to ensure that the water in the water distribution pool 211 can enter the hot tank assembly 1 through the water supply channel under the action of gravity.

[0052] In some embodiments, a water supply port 217 is formed on the bottom wall of the water diversion pool 211, and one end of the water supply channel away from the water supply connector 212 is connected to the water supply port 217. The water supply port 217 located on the bottom wall of the water diversion pool 211 can drain the water in the water diversion pool 211 to avoid wasting water resources. In addition, in the direction toward the water supply port 217, the bottom wall of the water diversion pool 211 extends downwardly and tilts, so that the water in the water diversion pool 211 can converge to the position of the water supply port 217 under the action of gravity, thereby preventing water from remaining in the water diversion pool 211 when the water in the water dispenser 100 is emptied.

[0053] According to some embodiments of the utility model, the water inlet and outlet waterway plate 2 includes: a main body 21 and a hot water outlet 22, the water distribution pool 211, the water supply channel and the water supply joint 212 are all formed in the main body 21, the hot water outlet 22 is arranged in the main body 21, the second water outlet joint 222 and the water outlet channel 221 are all formed in the hot water outlet 22, and the high temperature resistance index of the hot water outlet 22 is greater than the high temperature resistance index of the main body 21. In other words, the water supply channel for supplying water to the hot tank assembly 1 is arranged on the main body 21 with a relatively low high temperature resistance index, and the water outlet channel 221 for discharging hot water in the hot tank assembly 1 is arranged on the hot water outlet 22 with a higher high temperature resistance index, wherein the hot water outlet 22 with a higher high temperature resistance coefficient has better high temperature resistance performance, and the temperature that the hot water outlet 22 can withstand is higher than the temperature that the main body 21 can withstand. In this way, the hot water outlet 22 can be better prevented from carbonizing under the influence of the high temperature of hot water when transporting hot water, thereby improving the reliability and safety of the hot water outlet 22. In addition, since the temperature of the water in the water distribution tank 211 and the water supply pipeline is relatively low, the requirement for the high temperature resistance of the main body 21 is low, that is, the main body 21 has low requirement for the high temperature resistance of the material, which is conducive to reducing production costs.

[0054] According to some embodiments of the utility model, the main body 21 and the hot water outlet 22 are independently molded. That is to say, the main body 21 is an independently molded part and the hot water outlet 22 is also an independently molded part, wherein the structure of the independent main body 21 and the structure of the independent hot water outlet 22 are simpler than the structure of the water inlet and outlet waterway plate 2, and the difficulty of processing and molding is low. For example, the mold when the main body 21 and the hot water outlet 22 are separately produced by injection molding is also simpler. As a result, the difficulty of production and processing of the main body 21 and the hot water outlet 22 can be well reduced, and the synchronous production of the main body 21 and the hot water outlet 22 can be achieved, which is conducive to improving the production efficiency of the main body 21 and the hot water outlet 22.

[0055] According to some embodiments of the utility model, the main body 21 and the hot water outlet 22 are detachably connected. That is, the connection between the main body 21 and the hot water outlet 22 can be released, that is, the main body 21 and the hot water outlet 22 can be separated after the main body 21 and the hot water outlet 22 are connected. Therefore, during the use of the water dispenser 100, when one of the main body 21 or the hot water outlet 22 is damaged, such as when the hot water outlet 22 is damaged, the hot water outlet 22 can be removed from the main body 21, and only the hot water outlet 22 can be replaced, without replacing the entire water inlet and outlet waterway plate 2. Therefore, the maintenance cost of the water inlet and outlet waterway plate 2 in the later stage can be well reduced.

[0056] According to some embodiments of the utility model, the lower surface of the main body 21 is provided with a buckle 213 and a connecting hole (not shown in the figure), and the hot water outlet 22 is connected with the buckle 213 by snapping and forming an assembly hole opposite to and connected with the connecting hole. That is to say, on the basis of the main body 21 being connected with the hot water outlet 22 by snapping and connecting through the buckle 213, a connecting piece can also be used to cooperate with the connecting hole and the assembly hole to strengthen the connection strength between the main body 21 and the hot water outlet 22. Thus, the connection position between the main body 21 and the hot water outlet 22 can be increased well, so that the connection strength between the main body 21 and the hot water outlet 22 can be improved to improve the structural stability of the water inlet and outlet waterway plate 2. In addition, the snap-fitting mode is easy to implement, and the connection and disassembly difficulty is low. At the same time, after the snap-fitting of the buckle 213 and the hot water outlet 22, a good positioning and holding effect can be provided for the connection between the connecting hole and the assembly hole, so that the difficulty of cooperation between the buckle 213 and the hot water outlet 22 can be reduced, which is conducive to improving the assembly efficiency of the water inlet and outlet waterway plate 2.

[0057] According to some embodiments of the utility model, the main body 21 is an integrally formed part. Therefore, the integrally formed structure can not only ensure the structural and performance stability of the main body 21, but also facilitate molding and simple manufacturing, and eliminate the assembly parts and connection procedures used for connecting different parts of the main body 21, such as the water distribution tank 211 and the water supply connector 212, so the production cost is low and the assembly efficiency of the main body 21 is greatly improved. Moreover, the integrally formed structure has higher overall strength and stability and longer service life.

[0058] In some embodiments, the hot water outlet 22 is an integrally formed part for easy molding, higher overall strength and stability, and longer service life.

[0059] According to some embodiments of the utility model, the main body 21 is a polypropylene part. Among them, the polypropylene material is light and environmentally friendly, which is conducive to reducing the weight of the main body 21 and ensuring the safety of the water dispenser 100. At the same time, the polypropylene material has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high-wear processing performance, etc., which is conducive to improving the structural stability of the main body 21 and extending the service life of the main body 21. The hot water outlet 22 is a polyphenylene sulfide part. Among them, the polyphenylene sulfide material has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, excellent electrical properties, etc., and the polyphenylene sulfide material has better high temperature resistance than the polypropylene material. For example, the polyphenylene sulfide material can withstand a high temperature of 260 degrees Celsius, so that the high temperature resistance of the hot water outlet 22 can be better guaranteed to extend the service life and safety of the hot water outlet 22.

[0060] According to some embodiments of the utility model, the hot pot assembly 1 also has a first exhaust port 114 connected to the heating chamber 111, and the water inlet and outlet waterway plate 2 is formed with an exhaust chamber 214 connected to the first exhaust port 114 and the external space. That is to say, the heating chamber 111 is connected to the exhaust chamber 214 through the first exhaust port 114, and the exhaust chamber 214 is connected to the external space, so that the heating chamber 111 can be further connected to the external space through the exhaust chamber 214. Among them, when the heating element 112 is working, a large amount of water vapor will be generated after the water temperature in the heating chamber 111 increases, causing the pressure in the heating chamber 111 to increase accordingly. Therefore, the heating chamber 111 is connected to the external space through the first exhaust port 114 and the exhaust chamber 214, so that the thermal pressure generated during the heating process can be discharged in time through the first exhaust port 114 and the exhaust chamber 214 to prevent damage caused by excessive pressure in the heating chamber 111. Furthermore, during the process of filling water into the heating chamber 111 , the gas in the heating chamber 111 can be discharged in time through the first exhaust port 114 and the exhaust chamber 214 to ensure that the water flow can smoothly enter the heating chamber 111 , thereby ensuring the stability of the water filling in the heating chamber 111 .

[0061] In a specific example, the first exhaust port 114 is formed at the top of the heating chamber 111, so as to prevent the water in the heating chamber 111 from affecting the discharge of the gas, so as to ensure the smooth discharge of the gas in the heating chamber 111. The water dispenser 100 further includes an exhaust pipe 6, one end of which is connected to the first exhaust port 114, an exhaust joint is formed on the water inlet and outlet waterway plate 2, the exhaust joint is connected to the exhaust chamber 214, and the other end of the exhaust pipe 6 is connected to the exhaust joint. The water inlet of the heating chamber 111 is formed at the bottom of the heating chamber 111, and the water outlet of the heating chamber 111 is formed at the top of the heating chamber 111. That is, the unheated water flows into the heating chamber 111 through the bottom of the heating chamber 111 under the action of gravity, and the density of the hot water is lower, so that the hot water in the heating chamber 111 is pushed by the incoming water flow to gather at the top of the heating chamber 111, so that the unheated water entering the heating chamber 111 can be better prevented from affecting the outlet water temperature of the hot tank assembly 1. In addition, the water flow in the present application does not need to be driven by a pump, which helps to simplify the structure of the water dispenser 100 and reduce costs.

[0062] According to some embodiments of the utility model, the bottom wall of the exhaust cavity 214 is higher than the bottom wall of the water dividing pool 211. That is, the bottom wall of the exhaust cavity 214 is located above the bottom wall of the water dividing pool 211. Thus, the influence of the high-temperature gas in the exhaust cavity 214 on the water temperature in the water dividing pool 211 can be reduced, that is, the heat of the high-temperature gas entering the exhaust cavity 214 is prevented from being transferred to the normal-temperature water in the water dividing pool 211, causing the temperature of the normal-temperature water to rise, so as to meet the needs of users for drinking normal-temperature water.

[0063] According to some embodiments of the utility model, a partition 215 is provided between the exhaust cavity 214 and the water diversion pool 211. Thus, the partition 215 can form a physical partition between the exhaust cavity 214 and the water diversion pool 211, so that the partition 215 can better block the high-temperature gas in the exhaust cavity 214 from escaping into the water diversion pool 211, so as to reduce the transfer of heat in the exhaust cavity 214 to the water in the water diversion pool 211, that is, to avoid the heat of the high-temperature gas entering the exhaust cavity 214 from being transferred to the normal-temperature water in the water diversion pool 211, which causes the temperature of the normal-temperature water to rise, so as to meet the user's demand for drinking normal-temperature water.

[0064] According to some embodiments of the utility model, a reflux channel 2151 is formed at the partition 215 to connect the exhaust chamber 214 and the water separation pool 211. It can be understood that when the high-temperature gas in the heating chamber 111 enters the exhaust chamber 214 through the first exhaust port 114, the humidity of the water vapor therein is relatively high. Therefore, when the water vapor is cooled in the exhaust chamber 214 and releases heat and liquefies, water will be generated in the exhaust chamber 214. Therefore, by providing the reflux channel 2151 connecting the exhaust chamber 214 and the water separation pool 211, the water in the exhaust chamber 214 can be returned to the water separation pool 211 through the reflux channel 2151, so that the waste of water in the exhaust chamber 214 can be better avoided, and at the same time, the water can be prevented from remaining in the exhaust chamber 214 for a long time to generate mud, bacteria, etc., which is conducive to ensuring the cleanliness of the exhaust chamber 214. In addition, by arranging the reflux channel 2151 at the partition 215, the difficulty of processing and forming the reflux channel 2151 can be reduced.

[0065] In some embodiments, the bottom wall of the exhaust chamber 214 extends downwardly inclined in the direction toward the return channel 2151, that is, the end of the return channel 2151 connected to the exhaust chamber 214 is located at the lowest point of the exhaust chamber 214, thereby ensuring that the water in the exhaust chamber 214 can converge toward the return channel 2151 under the action of gravity to ensure that it is drained.

[0066] In some embodiments, the width of the reflux channel 2151 ranges from 0.8 mm to 1.2 mm. The wider the reflux channel 2151 is, the faster the water in the exhaust cavity 214 flows back to the water diversion pool 211, but the greater the possibility that the water in the exhaust cavity 214 enters the water diversion pool 211 before cooling down, and the greater the amount of water entering the water diversion pool 211 per unit time. On the contrary, the narrower the reflux channel 2151 is, the slower the water in the exhaust cavity 214 flows back to the water diversion pool 211, but the less likely the water in the exhaust cavity 214 enters the water diversion pool 211 before cooling down, and the smaller the amount of water entering the water diversion pool 211 per unit time. Thus, it is possible to avoid the reflux channel 2151 being too narrow to affect the reflux speed, and it is possible to avoid the reflux channel 2151 being too wide to cause the water in the exhaust cavity 214 to enter the water diversion pool 211 before cooling and the amount of hot water entering the water diversion pool 211 per unit time to be too large, thereby reducing the impact on the water temperature in the water diversion pool 211 while ensuring the reflux speed of the water in the exhaust cavity 214. The width of the reflux channel 2151 can be 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, 1.05 mm, 1.1 mm, 1.15 mm, 1.2 mm, etc., and no specific limitation is made here.

[0067] According to some embodiments of the utility model, an upwardly protruding exhaust nozzle 216 is formed on the bottom wall of the exhaust cavity 214, an exhaust channel 2161 is formed in the exhaust nozzle 216, and a second exhaust port 2162 communicating with the exhaust channel 2161 is formed at the upper end of the exhaust nozzle 216, and the first exhaust port 114 is communicated with the exhaust cavity 214 through the exhaust channel 2161 and the second exhaust port 2162. In other words, the second exhaust port 2162 is higher than the bottom wall of the exhaust cavity 214, so that the exhaust nozzle 216 can block the water in the exhaust cavity 214, so as to prevent the water in the exhaust cavity 214 from entering the exhaust channel 2161 through the second exhaust port 2162 and affecting the normal discharge of the gas in the heating cavity 111.

[0068] According to some embodiments of the utility model, a partition 215 is provided between the exhaust cavity 214 and the water separation pool 211, and the second exhaust port 2162 is located above the partition 215. That is to say, the second exhaust port 2162 is higher than the upper edge of the partition 215, which can further increase the interval between the second exhaust port 2162 and the water separation pool 211 in the vertical direction. It can be understood that the farther the interval between the two is, the lower the efficiency of heat transfer between the two. Thus, the influence of the high-temperature gas discharged through the second exhaust port 2162 on the water temperature in the water separation pool 211 can be well reduced, that is, the water temperature in the water separation pool 211 is kept at room temperature to meet the user's demand for drinking water at room temperature.

[0069] In a specific example, a first water outlet 218a and a second water outlet 218b are formed on the water inlet and outlet waterway plate 2, the first water outlet 218a is connected to an end of the water outlet channel 221 away from the second water outlet joint 222, and the second water outlet 218b is directly connected to the water distribution tank 211. Therefore, during the use of the water dispenser 100, the user can receive hot water through the first water outlet 218a, and can also directly receive normal temperature water in the water distribution tank 211 through the second water outlet 218b.

[0070] In a specific example, the water dispenser 100 also includes a cold tank assembly 4, which includes a cold tank 41 and a refrigeration module 42.

The cold tank 41 has a first pipe joint, a second pipe joint and a third pipe joint connected to the refrigeration cavity 411. A first flow channel and a second flow channel are formed in the water inlet and outlet waterway plate 2. A fourth pipe joint and a fifth pipe joint are also formed on the water inlet and outlet waterway plate 2. The fourth pipe joint is connected to the water diversion pool 211 through the first flow channel, and the fifth pipe joint is connected to the second flow channel. A third water outlet 218c is formed at one end of the second flow channel away from the fifth pipe joint.
