[0032] Specifically, an installation space (not shown in the figure) is provided in the shell 10, and the hot tank 20 and at least part of the warm water pipeline 30 are installed in the installation space, so that the shell 10 protects the hot tank 20 and the warm water pipeline 30. The embodiment of the present application does not specifically limit the material used for the shell 10. For example, the material used for the shell 10 can be but is not limited to plastic material and stainless steel material. At the same time, the design of the shell 10 of the drinking water device 1 also combines ergonomic principles to improve the user experience. For example, control components such as water extraction buttons and power switches are designed on the shell 10 to be easy for users to reach and operate, so that the user can control various functions of the drinking water device 1 through the control components.

[0033] The hot tank 20 may include a hot tank shell (not shown in the figure) and a heater (not shown in the figure). The heater is disposed in the hot tank shell and is used to heat the water in the hot tank 20 to form hot water.

[0034] The warm water pipeline 30 includes a warm water tank 31, a warm water main pipe 32, a warm water outlet valve 33 and a first water outlet 34 which are connected in sequence along the flow direction of the warm water. It can be understood that the warm water tank 31 is used to store normal temperature water, the first water outlet 34 is arranged on the outer shell 10, and the first water outlet 34 is used to discharge the warm water in the warm water tank 31, that is, when taking warm water, the warm water passes through the warm water tank 31, the warm water main pipe 32 and the warm water outlet valve 33 in sequence and flows out from the first water outlet 34 for users to drink.

[0035] See also Figure 2-Figure 3 Furthermore, the hot water pipeline 30 also includes a hot water branch 35 and a first control valve 581, one end of the hot water branch 35 is connected to the hot water main pipe 32, and the other end of the hot water branch 35 is connected to the hot tank 20, and the first control valve 581 is arranged on the hot water branch 35.

[0036] When taking warm water, the warm water outlet valve 33 is turned on and the first control valve 581 is closed. At this time, warm water flows out from the warm water tank 31, the warm water main pipe 32, the warm water outlet valve 33 and the first water outlet 34 in sequence.

[0037] When sterilizing the warm water pipeline 30 , the warm water outlet valve 33 is closed, the first control valve 581 is turned on, and hot water flows back to the warm water tank 31 from the hot tank 20 , the warm water branch 35 and the warm water main 32 in sequence to sterilize the warm water pipeline 30 .

[0038] It should be noted that when the hot tank 20 needs to be replenished with water, the warm water outlet valve 33 is closed, the first control valve 581 is turned on, and the warm water passes through the warm water tank 31, the warm water main 32, and the warm water branch 35 in sequence to replenish the hot tank 20. That is, the warm water tank 31 and the hot tank 20 can be connected through the warm water main 32 and the warm water branch 35, and when the first control valve 581 is turned on, the warm water can be used to replenish the hot tank 20 through the warm water main 32 and the warm water branch 35, and the hot water in the hot tank 20 can also flow back to the warm water tank 31 through the warm water branch 35 and the warm water main 32 to achieve the sterilization of the warm water pipeline 30.

[0039] Please continue reading Figure 2-Figure 3 Furthermore, the connection point between the warm water branch 35 and the warm water main pipe 32 is arranged between the hot tank 20 and the warm water outlet valve 33. When the warm water pipeline 30 is sterilized, hot water flows back to the warm water tank 31 from the warm water branch 35 and the warm water main pipe 32, and the connection point between the warm water branch 35 and the warm water main pipe 32 is arranged between the hot tank 20 and the warm water outlet valve 33 to increase the area of ​​the hot water flowing through the warm water main pipe 32. In this way, the sterilization area of ​​the warm water pipeline 30 is increased. At the same time, when the hot water flows through the connection point between the hot water branch 35 and the warm water main pipe 32, the hot water can sterilize the water inlet of the warm water outlet valve 33.

[0040] In the embodiment of the present application, when taking warm water, the warm water outlet valve 33 is turned on, the first control valve 581 is closed, and the warm water flows out from the warm water tank 31, the warm water main pipe 32, the warm water outlet valve 33 and the first water outlet 34; when replenishing water to the hot tank 20, the warm water outlet valve 33 is closed, the first control valve 581 is turned on, and the warm water is replenished from the warm water tank 31, the warm water main pipe 32, and the warm water branch 35 to the hot tank 20; when sterilizing the warm water pipeline 30, the warm water outlet valve 33 is closed, the first control valve 581 is turned on, and the warm water flows out from the warm water tank 31, the warm water main pipe 32, and the warm water branch pipe 35 to the hot water. The control valve 581 is turned on, and the hot water flows back to the warm water tank 31 from the hot tank 20, the warm water branch 35, and the warm water main 32 in sequence. Therefore, in this embodiment, warm water is provided to the user through the warm water pipe 30, and water is replenished to the hot tank 20 through the warm water pipe 30. The two have a common pipe. Based on this, the hot water in the hot tank 20 can flow back to the warm water tank 31 along the warm water pipe 30, and then the warm water pipe 30 is sterilized, thereby reducing the amount of bacteria in the warm water pipe 30, making it healthier for users to drink water.

[0041] Please continue reading Figure 2-Figure 3In some embodiments, the warm water main 32 can be divided into a warm water common section 36 and a warm water outlet section 37 with the connection point between the hot water manifold 35 and the hot water main 32 as the boundary, wherein the warm water common section 36 is connected to the hot water tank 31, and the warm water outlet section 37 is connected to the hot water outlet valve 33. It can be understood that when taking warm water, the warm water flows from the hot water tank 31, the warm water common section 36 and the warm water outlet section 37 to the hot water outlet valve 33 in sequence. When the hot water outlet valve 33 is turned on, the warm water flows out from the first water outlet 34 for user use; when the hot water pipeline 30 is sterilized, the warm water outlet valve 33 is closed, the first control valve 581 is turned on, and the hot water flows back to the hot water tank 31 through the hot water manifold 35 and the warm water common section 36 in sequence to sterilize the hot water manifold 35 and the warm water common section 36, thereby reducing the amount of bacteria in the hot water pipeline 30.

[0042] See also Figure 4 In some embodiments, the drinking water device 1 also includes a first hot water pipeline 40, the first hot water pipeline 40 includes a first hot water outlet valve 41 and a first hot water pipe 42, the first hot water outlet valve 41 is connected to the first water outlet 34, one end of the first hot water pipe 42 is connected to the first hot water outlet valve 41, and the other end of the first hot water pipe 42 is connected to the hot tank 20.

[0043] When taking hot water, the first hot water outlet valve 41 is turned on and the warm water outlet valve 33 is closed, and hot water flows out from the heat tank 20, the first hot water pipe 42, the first hot water outlet valve 41 and the first water outlet 34 in sequence. At this time, the hot water will flow through the first hot water outlet valve 41 so that the hot water can sterilize the first hot water outlet valve 41. Moreover, the first water outlet 34 can take both warm water and hot water. After the user takes warm water from the first water outlet 34, a small amount of warm water will remain in the first water outlet 34, and the small amount of warm water remaining in the first water outlet 34 is exposed to the air for a long time, which can easily cause bacteria to grow in the first water outlet 34, resulting in a large amount of bacteria at the first water outlet 34. Therefore, by setting the first water outlet 34 shared by warm water and hot water, the user can indirectly take hot water from the first water outlet 34 to sterilize the first water outlet 34, thereby reducing the amount of bacteria in the first water outlet 34.

[0044] See also Figure 2Furthermore, in some embodiments, the drinking water device 1 also includes a cold water pipeline 50, and the cold water pipeline 50 includes a cold tank 51, a cold water main pipe 52, a cold water outlet valve 53 and a second water outlet 54 connected in sequence along the flow direction of the cold water. The cold tank 51 is used to cool water. The cold tank 51 can be an electronic ice tank or other refrigeration equipment. The embodiment of the present application does not specifically limit the type of the cold tank 51. The second water outlet 54 is arranged on the shell 10. The second water outlet 54 is used to discharge the cold water in the cold tank 51. That is, when taking cold water, the cold water passes through the cold tank 51, the cold water main pipe 52, and the cold water outlet valve 53 in sequence and flows out from the second water outlet 54 for the user to drink. When the cold water in the cold tank 51 is less, the cold tank 51 is also connected to the warm water tank 31 so that the water in the warm water tank 31 can replenish the cold tank 51.

[0045] Furthermore, the cold water pipeline 50 also includes a cold water branch 55 and a second control valve 582 . One end of the cold water branch 55 is connected to the cold water main pipe 52 , and the other end of the cold water branch 55 is connected to the hot tank 20 . The second control valve 582 is arranged on the cold water branch 55 .

[0046] When cold water is taken, the cold water outlet valve 53 is turned on and the second control valve 582 is closed. At this time, cold water flows out from the cold tank 51, the cold water main pipe 52, the cold water outlet valve 53 and the second water outlet 54 in sequence.

[0047] When the cold water pipe 50 is sterilized, the cold water outlet valve 53 is closed, the second control valve 582 is turned on, and the hot water formed in the hot tank 20 flows back to the warm water tank 31 from the hot tank 20, the cold water branch 55 and the cold water main 52 in turn to sterilize the cold water pipe 50 and reduce the amount of bacteria in the cold water pipe 50, so that users can drink healthier water.

[0048] Please continue reading Figure 2 In some embodiments, the cold water main pipe 52 can be divided into a cold water common section 56 and a cold water outlet section 57 with the connection point between the cold water branch 55 and the cold water main pipe 52 as the boundary.

[0049] Specifically, the cold water common section 56 is connected to the cold tank 51, and the cold water outlet section 57 is connected to the cold water outlet valve 53. It can be understood that when taking cold water, the cold water flows through the cold tank 51, the cold water common section 56, and the cold water outlet section 57 in sequence and flows to the cold water outlet valve 53. When the cold water outlet valve 53 is turned on, the cold water flows out from the second water outlet 54; when the cold water pipeline 50 is sterilized, the cold water outlet valve 53 is closed, and the second control valve 582 is turned on, and the cold water flows back to the cold tank 51 through the cold water manifold 55 and the cold water common section 56 in sequence to sterilize the cold water manifold 55, the cold water common section 56 and the cold tank 51. In this way, the amount of bacteria in the cold water pipeline 50 is reduced, so that users can drink water more healthily.

[0050] Please continue reading Figure 2 In some embodiments, the connection point between the hot water branch 35 and the hot water main pipe 32 is adjacent to the hot water outlet valve 33. In this way, when the hot water pipeline 30 is sterilized, hot water flows back from the hot water branch 35 and the hot water main pipe 32 to the hot water tank 31, and the connection point between the hot water branch 35 and the hot water main pipe 32 is closer to the hot water outlet valve 33. In this way, the sterilization area of ​​the hot water pipeline 30 is increased. At the same time, when the hot water flows through the connection point between the hot water branch 35 and the hot water main pipe 32, the hot water can sterilize the water inlet of the hot water outlet valve 33.

[0051] Please continue reading Figure 2 In other embodiments, the connection point between the cold water branch 55 and the cold water main pipe 52 is adjacent to the cold water outlet valve 53. In this way, when the cold water pipeline 50 is sterilized, hot water flows back from the cold water branch 55 and the cold water main pipe 52 to the cold tank 51, and the connection point between the cold water branch 55 and the cold water main pipe 52 is closer to the cold water outlet valve 53. In this way, the sterilization area of ​​the cold water pipeline 50 is increased. At the same time, when the hot water flows through the connection point between the cold water branch 55 and the cold water main pipe 52, the hot water can sterilize the water inlet of the cold water outlet valve 53.

[0052] Please continue reading Figure 2 In some other embodiments, the connection point between the hot water branch 35 and the warm water main pipe 32 is adjacent to the warm water outlet valve 33, and the connection point between the cold water branch 55 and the cold water main pipe 52 is also adjacent to the cold water outlet valve 53. At this time, when the first control valve 581 is turned on, the hot water in the hot tank 20 flows back from the hot water branch 35 and the warm water main pipe 32 to the warm water tank 31 to sterilize the warm water pipeline 30. When the second control valve 582 is turned on, the hot water in the hot tank 20 flows back from the cold water branch 55 and the cold water main pipe 52 to the cold tank 51 to sterilize the cold water pipeline 50. The connection point between the hot water branch 35 and the warm water main pipe 32 is closer to the warm water outlet valve 33, and the connection point between the cold water branch 55 and the cold water main pipe 52 is also adjacent to the cold water outlet valve 53. In this way, the sterilization area of ​​the pipeline of the drinking water device 1 is increased.

[0053] Please continue reading Figure 2 Based on the connection between the hot water branch 35 and the warm water main pipe 32, the warm water main pipe 32 is divided into a warm water common section 36 connected to the warm water tank 31 and a warm water outlet section 37 connected to the warm water outlet valve 33. In some embodiments, the hot tank 20 and the cold tank 51 are both higher than the warm water tank 31, that is, in the height direction AA of the drinking water device 1, the hot tank 20 and the cold tank 51 are both higher than the warm water tank 31 to reduce the width of the drinking water device 1 in the width direction BB. However, since the hot tank 20 and the cold tank 51 are both higher than the warm water tank 31, it is difficult for the warm water in the warm water tank 31 to flow directly to the first water outlet 34 through the warm water pipeline 30 and to flow to the second water outlet 54 through the cold water pipeline 50.

[0054] Please continue reading Figure 2 For this purpose, a third control valve 361 is provided on the warm water common section 36. When taking warm water, the third control valve 361 is turned on, and the warm water flows out from the warm water tank 31, the warm water main pipe 32, the warm water outlet valve 33 and the first outlet 34. The warm water common section 36 can be divided into a pumping section 362 and a middle section 363 with the third control valve 361 as the boundary, wherein the middle section 363 is connected to the warm water branch 35, and the pumping section 362 is connected to the warm water tank 31. The pumping section 362 is provided with a pumping pump 130, and the pumping pump 130 has a pumping port and a discharge port. Water inlet, the water pump 130 uses a mechanical device to make the diaphragm in the pump do reciprocating motion, thereby compressing the air in the pump chamber to form a vacuum, or stretching the air in the pump chamber to form a negative pressure. When a pressure difference is generated between the water inlet and the external atmospheric pressure, under the action of the pressure difference, the water pump 130 can press the warm water in the warm water tank 31 from the water inlet into the pump chamber, and then pump it out from the drain outlet through the reciprocating motion of the water pump 130. That is, when the water pump 130 is working, the warm water can be pumped to the warm water common section 36 and the warm water outlet section 37.

[0055] It should be noted that the hot tank 20 and the cold tank 51 are both higher than the warm water tank 31. When the warm water pipeline 30 and the cold water pipeline 50 are sterilized, the hot water in the hot tank 20 can flow back into the warm water tank 31 under the action of gravity.

[0056] Please continue reading Figure 2 Furthermore, the drinking water device 1 also includes a cold tank water inlet pipe 70, one end of the cold tank water inlet pipe 70 is connected to the cold tank 51, and the other end of the cold tank water inlet pipe 70 is connected to the warm water tank 31 through the pumping section 362, that is, the warm water in the warm water tank 31 is pumped into the pumping section 362 under the action of the pumping pump 130, and a fourth control valve 71 is provided on the cold tank water inlet pipe 70. When the fourth control valve 71 is turned on, the pumping section 362 is connected to the cold tank water inlet pipe 70, so that the warm water tank 31 replenishes water to the cold tank 51 through the pumping section 362 and the cold tank water inlet pipe 70.

[0057] It should be noted that the hot tank 20 can also be connected to the warm water tank 31 through the cold tank 51, and the warm water in the warm water tank 31 is replenished to the hot tank 20 in sequence from the pumping section 362, the cold tank drain pipe 81, the cold tank 51 main pipe and the cold water branch pipe 55. That is, the embodiment of the present application provides cold water to the user through the cold water pipeline 50 and the cold tank water inlet pipe 70, and replenishes water to the hot tank 20 through the cold water pipeline 50 and the cold tank water inlet pipe 70. The two have a common pipeline. Based on this, the hot water in the hot tank 20 can flow back to the warm water tank 31 along the cold water pipeline 50 and the cold tank water inlet pipe 70, and then sterilize the cold water pipeline 50 and the cold tank water inlet pipe 70, thereby reducing the amount of bacteria in the cold water pipeline 50 and the cold tank water inlet pipe 70, making it healthier for users to drink water.

[0058] Please continue reading Figure 2 Based on the fact that the hot tank 20 is higher than the warm water tank 31 , in other embodiments, a first water pump is provided on the warm water main pipe 32 , and the first water pump can pump the water in the warm water tank 31 and flow it through the warm water main pipe 32 and the warm water branch pipe 35 to replenish the hot tank 20 .

[0059] In some other embodiments, the cold tank 51 is higher than the warm water tank 31 , and a second water pump is provided on the cold tank water inlet pipe 70 . The second water pump can pump water in the warm water tank 31 and flow it through the cold tank water inlet pipe 70 to replenish water to the cold tank 51 .

[0060] It should be noted that the first water pump and the second water pump can be the same water pump (130). In this case, the water pump 130 is arranged on the pumping section 362 to improve the pumping efficiency of the water in the warm water tank 31 to the cold tank 51 or the hot tank 20.

[0061] Please continue reading Figure 2 In some embodiments, the drinking water device 1 also includes a water inlet 111 and a filtration system 110. The water inlet 111 is arranged on the outer shell 10 to facilitate the access to raw water. The water inlet 111 is connected to the filtration system 110. After the raw water is filtered by the filtration system 110, the water filtered by the filtration system 110 is supplied to the warm water tank 31 to replenish the warm water tank 31.

[0062] Furthermore, the cold tank water inlet pipe 70 may be directly connected to the filtering system 110 , so that the filtered water can directly replenish the cold tank 51 through the cold tank water inlet pipe 70 .

[0063] Please continue reading Figure 2 In some embodiments, the warm water tank 31 has an air pressure balance hole 31, which connects the inner cavity of the water tank with the outside world. A bacteria filter membrane 312 is arranged at the air pressure balance hole 31, that is, the bacteria filter membrane 312 can cover the air pressure balance hole 31. In this way, on the one hand, the bacteria filter membrane 312 can allow gas molecules to pass freely so that the air pressure in the warm water tank 31 is the same as the external air pressure, which is conducive to ensuring the stability of the air pressure in the warm water tank 31. On the other hand, the bacteria filter membrane 312 can filter bacteria to prevent bacteria in the air from entering the warm water tank 31. The area of ​​the bacteria filter membrane 312 is actually set according to the area of ​​the air pressure balance hole 31, and the area of ​​the bacteria filter membrane 312 is usually larger than the area of ​​the air pressure balance hole 31, so as to cover the air pressure balance hole 31.

[0064] Please continue reading Figure 2In some embodiments, an ultraviolet sterilization device 311 is provided in the warm water tank 31. For example, the ultraviolet sterilization device 311 can be provided on the bottom plate of the warm water tank 31 or on the side wall of the warm water tank 31, and the ultraviolet sterilization device 311 can be an ultraviolet sterilization lamp, or other ultraviolet sterilization devices, which is not specifically limited in the embodiments of the present application.

[0065] Exemplarily, when the ultraviolet sterilization device 311 is an ultraviolet sterilization lamp, when the ultraviolet sterilization lamp is working, the ultraviolet sterilization lamp will emit ultraviolet rays to sterilize the warm water in the warm water tank 31 through ultraviolet rays. The embodiment of the present application can be designed to work at intervals. It can be understood that, with a cycle of 2 hours, the ultraviolet sterilization lamp works for 40 minutes to sterilize the warm water in the warm water tank 31. After the ultraviolet sterilization lamp works for 40 minutes, the ultraviolet sterilization lamp is controlled to be turned off for 140 minutes. In this way, on the one hand, the ultraviolet sterilization device 311 can be satisfied to sterilize the warm water in the warm water tank 31, and on the other hand, the service life of the ultraviolet sterilization lamp can be extended.

[0066] Please continue reading Figure 2 In some embodiments, an overflow ultraviolet sterilization device 120 is provided on the warm water main pipe 32, and an overflow ultraviolet sterilization device 120 is provided on the cold water main pipe 52, or an overflow ultraviolet sterilization device 120 is provided on both the warm water main pipe 32 and the cold water main pipe 52. The embodiment of the present application does not make specific limitations on this, wherein the overflow ultraviolet sterilization device 120 can be an overflow ultraviolet sterilization lamp.

[0067] Exemplarily, both the warm water main 32 and the cold water main 52 are provided with an overflow ultraviolet sterilization device 120. When warm water flows through the warm water main 32, the overflow ultraviolet sterilization lamp works and emits ultraviolet rays, and the overflow ultraviolet sterilization lamp sterilizes the warm water in the warm water main 32 by ultraviolet rays; when cold water passes through the cold water main 52, the overflow ultraviolet sterilization lamp works and emits ultraviolet rays, and the overflow ultraviolet sterilization lamp sterilizes the cold water in the cold water main 52 by ultraviolet rays.

[0068] Please continue reading Figure 2 In some embodiments, an ultraviolet sterilization device 311 is provided in the warm water tank 31 , and an overflow ultraviolet sterilization device 120 is provided on both the warm water main pipe 32 and the cold water main pipe 52 .

[0069] Specifically, when taking warm water, the ultraviolet sterilization device 311 in the warm water tank 31 sterilizes the warm water, and the warm water flows into the warm water main pipe 32, and the flow-through ultraviolet sterilization device 120 on the warm water main pipe 32 is opened to further kill the bacteria remaining in the warm water tank 31; when taking cold water, the ultraviolet sterilization device 311 in the warm water tank 31 sterilizes the warm water, and the warm water flows from the pumping section 362 to the cold tank water inlet pipe 70, the cold tank 51 and the cold water main pipe 52, and the flow-through ultraviolet sterilization device 120 on the cold water main pipe 52 is opened to further kill the bacteria remaining in the warm water tank 31, that is, the warm water or cold water taken by the user has undergone double sterilization, thereby reducing the amount of bacteria in the pipeline in the drinking water device 1.

[0070] It should be noted that when sterilizing the warm water pipeline 30 or the cold water pipeline 50 , the over-flow ultraviolet sterilization device 120 on the warm water pipeline 30 and the cold water pipeline 50 is closed to extend the service life of the over-flow ultraviolet sterilization device 120 .

[0071] In some embodiments, the first water outlet 34 and the second water outlet 54 may be the same water outlet, or the first water outlet 34 and the second water outlet 54 may be different water outlets, which is not specifically limited in the embodiments of the present application.

[0072] When the first water outlet 34 and the second water outlet 54 are the same water outlet, warm water, cold water and hot water all flow out from the same water outlet, thus saving the manufacturing cost of the drinking water device 1 .

[0073] See also Figure 4 When the first water outlet 34 and the second water outlet 54 are different water outlets, the drinking water device 1 also includes a second hot water pipeline 60, the second hot water pipeline 60 includes a second hot water outlet valve 61 and a second hot water pipe 62, one end of the second hot water pipe 62 is connected to the second hot water outlet valve 61, and the other end of the second hot water pipe 62 is connected to the hot tank 20.

[0074] When taking hot water, the second hot water outlet valve 61 is turned on and the cold water outlet valve 53 is closed, and hot water flows out from the hot tank 20, the second hot water pipe 62, the second hot water outlet valve 61 and the second water outlet 54 in sequence. At this time, the hot water will flow through the second hot water outlet valve 61, so that the hot water can sterilize the second hot water outlet valve 61. Moreover, the second water outlet 54 can take both cold water and hot water. After the user takes cold water from the second water outlet 54, a small amount of cold water will remain in the second water outlet 54, and the small amount of cold water remaining in the second water outlet 54 will be exposed to the air for a long time, so that bacteria will grow in the second water outlet 54, resulting in a large amount of bacteria at the second water outlet 54. Therefore, by setting the second water outlet 54 shared by cold water and hot water, the user can indirectly take hot water from the second water outlet 54 to sterilize the second water outlet 54, thereby reducing the amount of bacteria in the second water outlet 54.

[0075] Please continue reading Figure 4 In some embodiments, the first control valve 581 and the second control valve 582 are integrally formed into a three-way control valve 58, or the first control valve 581 and the second control valve 582 are different control valves, which is not specifically limited in the embodiments of the present application.

[0076] Exemplarily, when the first control valve 581 and the second control valve 582 are integrated into a three-way control valve 58, the three-way control valve 58 is arranged on both the hot water branch 35 and the cold water branch 55. The hot water can be refluxed to at least one of the hot water branch 35 and the cold water branch 55 by controlling the on-off of the three-way control valve 58, and a three-way control valve 58 can be arranged to save the manufacturing cost of the drinking water device 1.

[0077] Exemplarily, the first control valve 581 and the second control valve 582 are different control valves. When the hot tank 20 is replenished with water through the warm water pipeline 30, the first control valve 581 is turned on, and warm water is replenished to the hot tank 20 from the warm water tank 31, the warm water main pipe 32, the warm water branch 35 and the first control valve 581. When the hot tank 20 is replenished with water through the cold water pipeline 50, the second control valve 582 is turned on, and cold water is replenished to the hot tank 20 from the cold tank 51, the cold water main pipe 52, the cold water branch 55 and the second control valve 582 to avoid mixing of warm water and cold water.

[0078] In some embodiments, the cold tank 51 has a cavity inside for storing cold water. When the cold water pipeline 50 is sterilized, the second control valve 582 is turned on, and hot water flows back to the cold tank 51 through the cold water branch 55 and the cold water main 52 for multiple times. At this time, the water stored in the cold tank 51 is hot water. When the user needs to use cold water after sterilizing the cold water pipeline 50, the cold tank 51 fails to refrigerate the hot water in time, so that the water flowing out of the second water outlet 54 is hot water, which can easily cause scalding to the user.

[0079] See also Figure 5 To this end, the drinking water device 1 also includes a cold tank drainage pipeline 80, which may include a cold tank drainage pipe 81 and a fifth control valve 82. One end of the cold tank drainage pipe 81 is connected to the cold tank 51, and the other end of the cold tank drainage pipe 81 is connected to the warm water tank 31. When hot water is retained in the cold tank 51, the fifth control valve 82 is turned on, and the hot water in the cold tank 51 flows back to the warm water tank 31 through the cold tank drainage pipe 81. In this way, on the one hand, the hot water in the cold tank 51 is discharged, and on the other hand, the hot water can sterilize the cold tank drainage pipe 81.

[0080] In some embodiments, since the capacity of the hot tank 20 for storing hot water is limited, the drinking water device 1 further includes a hot tank overflow pipeline 90 to prevent the hot water in the hot tank 20 from overflowing.

[0081] See also Figure 6 The hot tank overflow pipeline 90 includes a hot tank overflow pipe 91, one end of the hot tank overflow pipe 91 is connected to the hot tank 20, and the other end of the hot tank overflow pipe 91 is connected to the warm water tank 31. When the hot water in the hot tank 20 rises to the overflow position of the hot tank overflow pipe 91, the hot water in the hot tank 20 can flow back to the warm water tank 31 through the hot tank overflow pipe 91 to avoid the hot water in the hot tank 20 from overflowing, thereby improving the safety of the drinking water device 1.

[0082] Furthermore, the hot tank overflow pipeline 90 may also include a sixth control valve (not shown in the figure), which is arranged on the hot tank overflow pipe 91. That is, when it is necessary to keep the hot water in the hot tank 20 at a high water level, the sixth control valve is closed so that the hot water in the hot tank 20 will not flow back into the warm water tank 31 through the hot tank overflow pipe 91; when the hot water in the hot tank 20 is about to overflow, the sixth control valve is turned on, and the hot water in the hot tank 20 can flow back into the warm water tank 31 through the hot tank overflow pipe 91 to avoid the hot water in the hot tank 20 from overflowing, thereby improving the safety of the drinking water device 1.

[0083] It should be noted that the cold tank drain pipe 81 and the hot tank overflow pipe 91 can share part of the pipeline. At this time, the two ends of the hot tank overflow pipe 91 are respectively connected to the cold tank drain pipe 81 and the hot tank 20 to increase the shared pipeline, thereby reducing the manufacturing cost of the drinking water device 1.

[0084] See also Figure 7 Furthermore, in some embodiments, the drinking water device 1 also includes a hot tank drainage pipeline 100, and the hot tank drainage pipeline 100 includes a hot tank drainage pipe 101 and a seventh control valve 102, wherein the hot tank drainage pipe 101 is connected to the hot tank 20. When the seventh control valve 102 is turned on, the hot water in the hot tank 20 can be discharged to the outside of the drinking water device 1 through the hot tank drainage pipe 101.

[0085] See also Figure 7 In some embodiments, the warm water tank 31 has a first water level detection member 313 and a first water temperature detection member 314. The first water level detection member 313 can detect the water level in the warm water tank 31, so that when the water level of the warm water tank 31 is lower than the high water level, the filtration system 110 is controlled to replenish water to the warm water tank 31, so that the warm water tank 31 can be kept at a high water level, thereby improving the water output efficiency of the warm water tank 31, and further improving the water extraction efficiency of the user. Exemplarily, the first water level detection member 313 includes at least one of a float type water level switch, a pressure type water level sensor, an ultrasonic water level sensor, a radar water level gauge, a photoelectric water level sensor, a capacitive water level sensor, a guided wave radar water level gauge, and a probe water level sensor. The first water temperature detection member 314 can include at least one of an immersion thermometer, a Pt100 platinum resistance temperature sensor, an electronic temperature sensor, an infrared thermometer, and a Cu50 copper resistance temperature sensor. In the embodiment of the present application, there is no limitation on the specific forms of the first water level detecting element 313 and the first water temperature detecting element 314 .

[0086] In a specific embodiment, the first water level detection member 313 may include a low water level probe and a high water level probe. When the filter system 110 replenishes water to the warm water tank 31, when the high water level probe in the warm water tank 31 detects a high water level, the filter system 110 is controlled to stop replenishing water to the warm water tank 31 to prevent the water in the warm water tank 31 from overflowing. When the pump 130 extracts water from the warm water tank 31, after the water in the warm water tank 31 drops from the high water level for the pumping time, the pump 130 is controlled to stop pumping water, and the filter system 110 is controlled to replenish water to the warm water tank 31 until the water in the warm water tank 31 returns to the high water level. Exemplarily, the pumping time may be 30 seconds, 1 minute, 1 minute and 30 seconds, 2 minutes, 2 minutes and 30 seconds...

[0087] See also Figure 7In some embodiments, the hot tank 20 has a second water level detection member 21 and a second water temperature detection member (not shown in the figure). The second water level detection member 21 can detect the water level in the hot tank 20, so that when the water level in the hot tank 20 is lower than the high water level, the warm water tank 31 is controlled to replenish water to the hot tank 20, so that the water level in the hot tank 20 is kept at the high water level, thereby improving the water output efficiency of the hot tank 20, and further improving the water extraction efficiency of the user. The second water temperature detection member can detect the temperature in the hot tank 20, so that the drinking water device 1 heats the water in the hot tank 20, so that the user can use hot water. Exemplarily, the second water level detection member 21 includes at least one of a float water level switch, a pressure water level sensor, an ultrasonic water level sensor, a radar water level gauge, a photoelectric water level sensor, a capacitive water level sensor, a guided wave radar water level gauge, and a probe water level sensor. The second water temperature detection member can include at least one of an immersion thermometer, a Pt100 platinum resistance temperature sensor, an electronic temperature sensor, an infrared thermometer, and a Cu50 copper resistance temperature sensor. In the embodiment of the present application, there is no limitation on the specific forms of the second water level detecting element 21 and the second water temperature detecting element.

[0088] In a specific embodiment, the second water level detection component 21 may include a low water level probe, a middle water level probe, a high water level probe and an overflow water level probe. When the middle water level probe of the hot tank 20 detects that the water level in the hot tank 20 drops below the middle water level, the drinking water device 1 controls the warm water outlet valve 33 to close, and controls the first control valve 581 and the third control valve 361 to open, and controls the water pump 130 to extract the warm water in the warm water tank 31, and enters the hot tank 20 through the warm water main pipe 32 and the warm water branch pipe 35 until the high water level probe of the hot tank 20 detects that the water in the hot tank 20 is at a high water level. This can improve the water extraction efficiency of users in taking hot water, and can prevent the hot tank 20 from drying out, so as to reduce the probability of damage to the hot tank 20, so that the hot tank 20 can have a longer service life, so that the drinking water device 1 can have a longer service life.
