The atmospheric pressure sensor 52 is fixed on the outer wall of the fixed box 26. The atmospheric pressure sensor 52 is electrically connected to the electric control box 27.

[0020] The fixed box 26 is provided with ventilation holes;

[0021] The air outlet pipe 46 is fixed on the partition 6 through an air outlet pipe fixing seat 48 .

[0022] In this embodiment, the water inlet pipe 18 is connected to the water source. When the electric float liquid level transmitter 14 floats up, the electric float liquid level transmitter 14 controls the electric control valve 19 through the electric control box 27 to cut off the water flow and stop the water inlet; when the electric float liquid level transmitter 2 15 drops, the electric float liquid level transmitter 2 15 controls the electric control valve 19 to open through the electric control box 27; when the electric float liquid level transmitter 3 16 floats up, the electric float liquid level transmitter 3 16 controls the electric control valve 2 12 to close through the electric control box 27. The temperature sensor 20 can monitor the water temperature in real time. When the water temperature reaches 100 degrees, the electric control box 27 controls the heating The hot plate 2 19 stops heating and controls the electric control valve 3 22 to open. When the electric float liquid level transmitter 4 17 drops, the electric float liquid level transmitter 4 17 controls the electric control valve 3 22 to close through the electric control box 27, and controls the electric control valve 2 12 to open. When water enters and exits the heating box 55, the electric control box 27 controls the electric control valve 6 56 to open for ventilation. When the electric float liquid level transmitter 5 18 floats up, the electric float liquid level transmitter 5 18 controls the electric control valve 3 22 to close through the electric control box 27. The temperature sensor 13 can monitor the water temperature in real time. When the water temperature is lower than 100 degrees, the heating plate 1 5 is controlled to heat through the electric control box 27.

[0023] When drinking warm water is needed, the electric control valve 4 23 is first controlled to open by the electric control box 27. At this time, the hot water enters the quick cooling box 31. In the process of hot water entering the quick cooling box 31, some of the air in the quick cooling box 31 will enter the fixed box 26 through the return air hose 36 and the reversing valve stem 37. As the hot water in the quick cooling box 31 increases, the quick cooling box 31 will become heavier and heavier. At this time, the quick cooling box 31 will compress the spring 1 30 and move downward. During the movement, when the quick cooling box 31 touches the limit switch 1 35, the limit switch 1 35 controls the electric control valve 4 23 to close through the electric control box 27. At the same time, the electric control box 27 controls the electric push rod 39 and the vacuum pump 40 to start. The electric push rod 39 pushes the reversing valve stem 37 upward. At this time, the vacuum pump 40 extracts the air in the quick cooling box 31, and the extracted air and water vapor enter the inner shell box 2 above the partition 6 through the return air pipe 44 and the outlet pipe 46 to heat the cold water. , to avoid heat waste, the pressure in the rapid cooling box 31 will become lower and lower, the boiling point of water will become lower and lower, and the hot water in the rapid cooling box 31 will always be in a boiling state. The boiling hot water will consume a lot of its own heat, thereby lowering its own temperature. In the process of the pressure in the rapid cooling box 31 becoming lower and lower, the pressure in the atmospheric pressure sensor 52 is the same as the pressure in the rapid cooling box 31. When the water temperature in the rapid cooling box 31 reaches the set value, the atmospheric pressure sensor 52 will control the vacuum pump 40 to be closed through the electronic control box 27, control the electronic control valve five 24 to be opened, control the electric push rod 39 to return to its original position, and the reversing valve stem 37 returns to its original position under the action of the spring two 43; in the process of receiving warm boiled water, the liquid level in the rapid cooling box 31 becomes lower and lower, and under the action of the spring one 30, the rapid cooling box 31 will return to its original position until it touches the travel switch two 54, and the travel switch two 54 controls the electronic control valve four 23 to be opened through the electronic control box 27.
