The main body 110 has a space of a predetermined size where each component can be positioned and maintains a vacuum state.

The water tank part 120 is comprised from the cold water tank 121 and the hot water tank 122, and accommodates cold water and hot water, respectively. Each of these tanks has a dual structure as shown in FIG. 2 and maintains a vacuum state.

That is, the water tank unit 120 has an advantage of separating the cold water tank 121 and the hot water tank 122 separately, reducing heat loss, and shortening the temperature control time during cold / hot switching.

In addition, when driving the device through such a vacuum state, it is possible to reduce the noise of the main body 110, to prevent condensation, and to easily store the temperature of the cold and hot water accommodated in the water tank 120.

At this time, the method for maintaining the vacuum state is as follows.

When the air ball 160 is operated, the air is discharged from the cold water tank 121 and the hot water tank 122, and the air can be discharged to the outside through the exhaust of the air valve 170, and the cold water tank 121 and the hot water tank By measuring the pressure of the air through the pressure sensor 123 connected from the 122, when the desired vacuum state is reached, by blocking the air discharge through the air valve 170, the main body 110, the cold water tank 121 And a vacuum is induced in the hot water tank 122.

On the other hand, a brief description of how to measure the volume is as follows.

According to Boyle's law, pressure and volume are inversely proportional, so the pressure can be kept constant and the volume can be expressed in time using a metering pump.

When the eruption ball pump 160 is operated, air is released from the main body 110, the cold water tank 121, and the hot water tank 122, which is measured by the pressure sensor 123. When the pressure is constant, the air is shut off through the air valve 170. At this time, when the air pump 160 is used as a metering pump, the amount of air (m3) is discharged per unit time (sec), and the volume of the main body unit 110, the cold water tank 121, and the hot water tank 122 is measured. By subtracting the discharge air (m3 / sec) into the volume of the refrigerant in the hot and cold water bath can be calculated.

In addition, since the temperature of the cold and hot water tank changes, Charles' law, which is a law of volume change according to temperature, is also applicable.
