Description

{A FAN HEATER USING SUPERSATURATED STEAM}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hot air fan, and more particularly, to a hot air fan using superheated steam using superheated steam as a heat source.

Generally, heat sources are secured by using electric heat, coal, oil, wood, pellets, etc. in the use of hot air fans in places requiring heat sources such as homes, factories, and facility houses.

However, this causes problems such as oil price hike, fine dust pollution due to dust, and electric power tax increase in facility houses and factories due to the use of electric hot air blowers, which is pointed out as a cause of increase in production cost.

Thus, in many fields using conventional oil boilers and electric heat fans, the production cost of production items due to the increase in oil price and electric charge is burdened. In the case of warm air caused by convection heat, harmfulness to health becomes a problem, The use of oil boilers in the case of facility houses has an adverse effect on crops due to excessive CO2 emission. In addition, as government subsidies reduce the use of hot air fans, users are not able to supply enough heat in the places they need.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a hot air fan using superheated steam as a heat source.

Another object of the present invention is to provide a hot air fan which is compact and easy to install and move and is easy to use.

SUMMARY OF THE INVENTION The object of the present invention is to provide a water purifier, comprising: a body having a space formed therein and generating superheated water vapor by heating water; A blowing unit installed at an upper portion of the body so as to be rotatable in a vertical direction and blowing overheated water vapor supplied through the connection pipe from the body forward together with air; And a support unit installed on the upper side of the body and supporting the blower unit.

According to an aspect of the present invention, the space portion is partitioned into a plurality of spaces by partition walls, and includes a water tank portion in which water is stored, and a water supply pump and a pipe, which are formed on the upper side of the water tank portion, A heater for heating the water supplied through the pipe by at least one heater, and a controller for controlling the operation of the heater, the heater being divided at one side of the water tank, And a control unit to which the control unit is installed.

According to another aspect of the present invention, the heating unit may include a first heater unit for heating water to generate steam, and a second heater unit for heating the steam to generate superheated steam.

According to another aspect of the present invention, there is provided an air conditioner, comprising: a cylindrical housing having both front and rear ends opened; a suction fan installed in the housing and rotated by a driving motor; And may include a spray pipe for spraying superheated water vapor.

According to another aspect of the present invention, the blower may further include a plurality of auxiliary heaters installed in front of the spray tube.

According to another aspect of the present invention, the water supply pump and the injection amount of water supplied from the water tank portion to the heating portion can be adjusted by the water supply pump.

In addition, according to the present invention, it is possible to increase the density of the air by using water, and to provide a composite heat source having about eight times the heat amount of the hot air including the radiative heat transfer, the convection heat and the condensation heat, Because it can supply radioactive gas, it is suitable for large buildings and large public places.

In addition, according to the present invention, ionized minerals contained in the groundwater can be sprayed on crops to help grow crops. Therefore, in the case of the facility house, over 70 kinds of ionized calcium or magnesium Branch elements can be sprayed on the crops to promote reproduction and nutrition.

In addition, according to the present invention, in the use of latent heat and sensible heat of water, superheated water vapor having nanometer-sized water vapor particles is generated by reheating water after heating the water by using latent heat and sensible heat of water according to the present invention. As it expands to ~ 4,000 times and is mixed with the outside air, it can quickly diffuse to the same density throughout the space and can transfer heat to the organism without heat loss.

In addition, according to the hot air heater using the superheated water vapor according to the present invention, the electricity rate is 1/3 to 1/5 of that of the conventional hot air fan, and since the human vapor is applied to the human body, it is effective for the skin health of the worker.

In addition, according to the present invention, it is possible to prevent damage to crops due to excessive CO 2 emission, and to form a water film on the leaves of a crop to prevent virus infection and leaf blotting, The fungi absorb the water molecules injected from the hot air fan due to their characteristics, and the tissue is destroyed.

Also, when a hot air heater using superheated steam according to the present invention is applied to a facility house, convection in the facility house is well performed with a strong air blowing ability, and there is little difference in temperature distribution and water supply depending on the place, In the case of fruit, since there are many fine particles of water, the shelf life is long.
