The difference is that the control unit 7 further includes a control panel 71. A water level gauge 72 that is connected and can measure the water level of the warm water tank 42.

When the user wants to drink hot water, as in the first preferred embodiment, the control member 66 is in the hot water position, and the water in the raw water tank 41 is heated to hot water via the heater 51, and the heat is passed through the heat. The water conduit 524 flows into the water collecting funnel 32 from the water outlet 611 of the water outlet pipe 61. When the user wants to drink warm water, the control member 66 is in the warm water position, as indicated by an arrow D, the temperature-increasing water pump 65 pressurizes the warm water in the warm water tank 42 and then exits the temperature. The water pipe 63 is output, and then the warm water flows from the outlet water pipe 63 to the water outlet 611, and flows into the water collecting funnel 32 of the base 3, while the control panel 71 controls the control member 66 in the warm water. Position, but the control panel 71 does not directly replenish the water in the raw water tank 41, but waits until the water level measuring device 72 measures that the water level in the warm water tank 42 is lower than a set water level. When the water level measuring device 72 sends a signal to the control panel 71, the control panel 71 controls the water in the raw water tank 41 to be heated by the heaters 51 as indicated by the arrow E, so that after heating The hot water flows into the warm water tank 42 via the water outlet pipe 61 as described above to continuously replenish the amount of water in the warm water tank 42 until the water level measuring device 72 measures the inside of the warm water tank 42. When the water level reaches the set water level, the amount of water in the warm water tank 42 is stopped.

In the second preferred embodiment, the water level in the warm water tank 42 is measured by the water level measuring device 72.

It is high, and the height of the highest point of the water pipe 62 is higher than the height of the control member 66, and the control member 66 is a two-way solenoid valve. In a normal time, the control member 66 is in the warm water position, the water outlet pipe 61 is in communication with the water delivery pipe 62, and the water outlet pipe 61 is not in communication with the water outlet 611, so when the user continues to drink warm water, the water level is made. When the measuring device 72 measures that the water level of the warm water tank 42 is lower than a set water level, the water in the raw water tank 41 can be heated and then flowed into the water delivery pipe 62 by the control member 66 to supplement the warm water tank 42. When the user drinks hot water, the control member 66 communicates the water outlet pipe 61 with the water outlet 611 at the hot water position, and the water in the raw water tank 41 is heated by the heater 51 and flows to the control member 66. Since the height of the highest point of the water pipe 62 is higher than the height of the control member 66 and the water outlet pipe 61 communicates with the water outlet 611, the hot water does not flow in the direction of the water pipe 62, but is affected by the flow of gravity. The water outlet 611 is in the lower direction and finally flows out of the water outlet 611 into the water collecting funnel 32. In the embodiment, the height of the water outlet pipe 61 and the water pipe 62 are different, so that the control member 66 can be a two-way electromagnetic valve, which is simple in structure and easy to manufacture, and can reduce the instant drinker 2 manufacturing cost.
