These thermoelectric elements are composed of a thermistor, which is a device using temperature variation of electric resistance, a device using Jeff Beck effect, which is a phenomenon in which electromotive force is generated by temperature difference, a Peltier device using Peltier effect, which is a phenomenon in which heat is absorbed or generated by current As shown in FIG.

The outside air supply unit supplies outside air to the thermoelectric element by rotating the fan so as to lower or raise the temperature of the outside air in contact with the thermoelectric element.

Therefore, the temperature of the outside air flowing into the temperature regulating unit 130 is controlled by the thermoelectric element, and then the temperature of the outside air is supplied to the base unit 111 through the mixing unit 190, 110). ≪ / RTI >

The liquid supply portion 141 is attached with a water supply automatic level switch or the like so as to automatically supply the amount of water to be contained in the vaporization portion 143 at an appropriate level.

The ultrasonic wave generator 142 generates ultrasound by vibrating with electricity. Generally, a piezoelectric element used as a piezo system, that is, a piezoelectric element that generates a piezoelectric effect when an electric current is applied, is used.

The piezoelectric phenomenon refers to the conversion of energy (conversion of mechanical energy and electrical energy) mediated by a permanent dipole caused by the asymmetry of the crystal of the piezoelectric element. That is, when mechanical energy is applied to a piezoelectric element, electrical energy is generated, and when electrical energy is applied to the piezoelectric element, mechanical energy is generated.

Here, the term " vaporization " means that the liquid is changed into a gas state. The vaporization process in the vaporization section 143 is as follows.

When the ultrasonic wave generated from the ultrasonic wave generator 142 is transmitted to the liquid, the liquid molecules in the liquid collide with each other and the vibration is transmitted between the molecules. Then, when the vibration touches the surface of the liquid, the liquid particles on the liquid surface protrude into the liquid surface in a fine granular state. This process occurs repeatedly, causing the liquid to change to a gaseous state, i.e., to vaporize.

Then, droplets of water protruding from the surface of the liquid are mixed with the gas, which is supplied to the mixing portion 190. Then, the gas is mixed with the air supplied from the temperature control unit 130 in the mixing unit 190, and then supplied to the storage unit 110.
