[0027] Embodiment 1

[0028] like Figures 1 to 4 As shown, an embodiment of the utility model discloses a water making system with boiled water function, comprising a pure water pipeline 1, a normal temperature water pipeline 2 and a boiled water pipeline 3, the water outlet end of the pure water pipeline 1 is respectively connected with the water inlet end of the normal temperature water pipeline 2 and the water inlet end of the boiled water pipeline 3, the normal temperature water pipeline 2 is closed, the boiled water pipeline 3 is opened, the pure water of the pure water pipeline 1 flows to the water inlet end of the boiled water pipeline 3, and then flows out of the boiled water through the water outlet end of the boiled water pipeline 3.

[0029] The room temperature pure water prepared by the pure water pipeline 1 flows into the boiled water pipeline 3, which heats the room temperature pure water and adjusts it into boiled water. The boiled water is then discharged for users to drink directly without waiting for it to cool down. This solves the problem in the prior art that the hot water from the under-sink water purifier needs to wait for a long time before the water temperature drops and becomes suitable for drinking.

[0030] In this embodiment, the boiled water pipeline 3 includes a flow control pump 31, a heat exchange module 32, an instant heating pipe 33, a first regulating valve 34, a first water inlet pipe 35 and a first water outlet pipe 36. The flow control pump 31 is arranged on the first water inlet pipe 35. The first end of the first water inlet pipe 35 is the water inlet end of the boiled water pipeline 3. The heat exchange module 32 has a first heat exchange pipe and a second heat exchange pipe for heat exchange. The second end of the first water inlet pipe 35 is connected to the water inlet end of the first heat exchange pipe, the water inlet end of the instant heating pipe 33 is connected to the water outlet end of the first heat exchange pipe, the water outlet end of the instant heating pipe 33 is respectively connected to the water inlet end of the second heat exchange pipe and the first water inlet of the first regulating valve 34, the water outlet end of the second heat exchange pipe is connected to the second water inlet of the first regulating valve 34, and the water inlet end of the first water outlet pipe 36 is connected to the water outlet of the first regulating valve 34.

[0031] The pure water prepared by the pure water pipeline 1 is transported to the first heat exchange tube by the flow control pump 31, and then heated by the instantaneous heating tube 33. The heated pure water flows in two directions, one direction flows to the first regulating valve 34, and the other direction flows to the second heat exchange tube. Since the first heat exchange tube and the second heat exchange tube perform heat exchange, the boiling water in the second heat exchange tube will be carried away by the normal temperature pure water in the first heat exchange tube to become warm water, and then merged through the first water inlet of the first regulating valve 34 and the second water inlet of the first regulating valve 34, and mixed into warm water of the required temperature, that is, boiled water, and then boiled water flows out from the water outlet end of the first water outlet pipe 36.

[0032] In this embodiment, the cold boiled water pipeline 3 includes a first NTC temperature sensor 371, which is disposed at the water inlet end of the instant heating pipe 33. The first NTC temperature sensor 371 is used to detect the pure water temperature at the water inlet end of the instant heating pipe 33.

[0033] In this embodiment, the cold boiled water pipeline 3 includes a second NTC temperature sensor 372, which is disposed at the outlet of the instant heating pipe 33. The second NTC temperature sensor 372 is used to detect the pure water temperature at the outlet of the instant heating pipe 33.

[0034] In this embodiment, the cold boiled water pipeline 3 includes a flow limiting device 38, and the flow limiting device 38 is arranged on the first water outlet pipe 36. When cold boiled water or boiling water is discharged, the opening is reduced to increase the pressure of the water in the instant heating pipe 33 to adjust the boiling point of the water, so that truly boiling water can be discharged.

[0035] Specifically, the flow limiting device 38 is a second regulating valve.

[0036] In some embodiments, the flow limiting device 38 is a small-bore tube, and the diameter of the small-bore tube is smaller than the diameter of the first water outlet pipe 36. The small-bore tube can also achieve the purpose of reducing the opening and increasing the pressure.

[0037] In some embodiments, the pure water pipeline 1 includes a composite filter element 11, an inlet valve 12, a booster pump 13, an RO filter element 14, a second water inlet pipe 15, a second water outlet pipe 16, a first connecting pipe 17 and a second connecting pipe 18. The composite filter element 11 includes a pre-filter element and a post-filter element separated from the pre-filter element.

The two ends of the second connecting pipe 18 are respectively connected to the water outlet end of the RO filter element 14 and the water inlet end of the post-filter element. The water inlet end of the second water outlet pipe 16 is connected to the water outlet end of the post-filter element. The water outlet end of the second water outlet pipe 16 is the water outlet end of the pure water pipeline 1.

[0038] The water inlet end of the second water inlet pipe 15 is used to connect tap water. The tap water enters the pre-filter element through the second water inlet pipe 15. The prepared clean water then enters the RO filter element 14 through the water inlet valve 12 and the booster pump 13. The pure water prepared by the RO filter element 14 enters the post-filter element through the second connecting pipe 18, and then flows to the normal temperature water pipeline 2 or the boiled water pipeline 3 through the second water outlet pipe 16.

[0039] Specifically, a first check valve 181 is provided on the second connecting pipe 18. The first check valve 181 prevents the water inlet of the post filter element from flowing back to the water outlet of the RO filter element 14.

[0040] In some embodiments, the pure water pipeline 1 includes a raw water TDS detector 171, and the raw water TDS detector 171 is disposed in the first connecting pipe 17. The raw water TDS detector 171 is used to detect the TDS value in the first connecting pipe 17.

[0041] In some embodiments, a flow meter 161 and a pure water TDS detector 162 are provided at the water outlet end of the second water outlet pipe 16 .

[0042] In this embodiment, the normal temperature water pipeline 2 includes a third water outlet pipeline 21 and a normal temperature water solenoid valve 22.

The switch of the third water outlet pipeline 21 is controlled by the normal temperature water solenoid valve 22.

[0043] In this embodiment, the water making system with boiled water function includes a reflux pipeline 4, the two ends of which are respectively connected to the branch ports of the second connecting pipeline 18 and the branch ports of the first connecting pipeline 17, and the branch port of the first connecting pipeline 17 is located between the water inlet valve 12 and the booster pump 13. A reflux pipeline 4 is added to the pure water pipeline 1 to solve the problem of high TDS of the first cup of water.

[0044] Specifically, the reflux pipeline 4 includes a reflux pipe 41, a second check valve 43 and a reflux solenoid valve 42. The second check valve 43 and the reflux solenoid valve 42 are arranged in the reflux pipe 41. The reflux solenoid valve 42 is used to control the switch of the reflux pipe 41.

Specifically, the water making system with boiled water function comprises a pure water pipeline 1, a normal temperature water pipeline 2 and a boiled water pipeline 3, the water outlet end of the pure water pipeline 1 is connected with the water inlet end of the normal temperature water pipeline 2 and the water inlet end of the boiled water pipeline 3 respectively, the normal temperature water pipeline 2 is closed, the boiled water pipeline 3 is opened, the pure water in the pure water pipeline 1 flows to the water inlet end of the boiled water pipeline 3, and then flows out of the boiled water through the water outlet end of the boiled water pipeline 3.
