The present invention relates to a hot air fan using an overheated steam, and more particularly, to supply a large amount of heat to an object by using a characteristic of rapidly discharging very large condensation heat when the superheated steam is liquefied by contacting a low temperature object surface. It is about a warmer.

In general, the hot air blower is installed in the rear of the heating element to blow air warmed by contact with the heating element.

Such a hot air fan blows heated air by contacting air with high temperature heat that is burned in an electric heater and a combustor that burns gas or petroleum while heating the heating element, and blows the heated air. It is divided into used household.

However, in the conventional electric heater, the air is heated by the electric heater, and in the process of rapidly heating the air in contact with the electric heater to a high temperature, oxygen is burned, the density of oxygen is lowered, and the air is further dried. Because the air is blown at, the air is dry and the heat capacity of the warm air is small and the efficiency is bad.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

1 is a view for explaining the basic concept of the present invention.

As shown in FIG. 1, water is partially filled in a ring-shaped water container 1 having an inner diameter and an outer diameter and having a predetermined height, and is applied to a through portion 2 formed to penetrate up and down inside thereof. A coil-shaped heater 3 that generates heat by a power source is provided.

Outside air is supplied to the upper portion through the penetrating portion 2, and when power is applied to the heater 3 in this state, the air is heated to rise to the upper portion and at the same time the water container 1 surrounding the heater 3 ) Is filled with water and becomes super over steam through the evaporation process of saturated water (100 ℃)-> steam (evaporation)-> saturated steam (100 ℃) by heating the heater (3).

This superheat steam is discharged through the discharge hole 1a formed in the upper surface of the water container 1 and mixed with the hot air heated by the heater 3.

In such a state, the air is introduced again from the outside to heat the air containing the overheat steam to the auxiliary heater 4 again, and then discharge the far infrared heat and the anion together with the overheat steam and the hot air.

Figure 2 is a graph for explaining the amount of heat of the superheat steam used in the present invention.

As shown in FIG. 2, air increases by 0.24 cal with each increase of 1 ° C., while water increases by 1 cal with 100 ° C. when increasing by 1 ° C., and saturated water (100 ° C.) → steam (evaporation). -> It becomes 639.1cal through evaporation of saturated steam (100 ℃), and 0.48cal increases after each 1 ℃ increase in superheated steam.

Therefore, the calorific value at 200 ° C of air becomes 200 ° C x 0.24cal = 48cal / g / ° C, while the calorific value at overheating steam 200 ° C is 639.1cal + (100 ° C x 0.48cal) = 687.1cal / g / ° C. .

On the other hand, it can be found as the volume V = nRT / P in the state equation PV = nRT of the ideal gas.

Where P is the atmospheric pressure of 1 atm, n is the number of moles, T is the absolute temperature, and R is the gas constant as 0.082 atm · L / mol · K.

Since 100 ° C is 373.15K in absolute temperature, the volume of steam at 100 ° C is {1/18} mol x 0.08 [atm · L / mol · K] x 373.15 [K] / 1 [atm] ≒ 1700cm ³ .

However, since the volume of water at 4 ° C. and 1 g is 1 g / 1 [g / cm ³ ] = 1 cm ³ , when the water at 4 ° C. changes to 100 ° C. steam, the volume expands to about 1,700 times.

Char's law states that if the pressure is constant, the volume of the gas is proportional to its absolute temperature. Using this, the volume becomes 1,700 x 1.27 = 2,159 when the water becomes overheated at 200 ° C.

Therefore, if the room is heated by blowing overheat steam at 200 ℃, the amount of heat is 687.1cal and the volume is increased by 2,159 times, which is 687.1 x 2,159 = 1,483,499cal, which is much higher than the heat of 200 ℃.

Therefore, according to the hot air fan using the superheat steam of the present invention, it is possible to supply more heat to the room than the hot air fan using air, so that the heating efficiency is better than the heating efficiency using the air.
