The present invention relates to a hot air heater used to heat the interior space of a greenhouse (vinyl house), and more particularly, a solid fuel (hereinafter referred to as "fuel") in a plurality of fuel tanks having a plurality of independent combustion tanks inside the warm air base. It is related to a hot air fan that supplies the heat generated by the combustion of each one to the inner space of the greenhouse (vinyl house) through a duct.

In general, the house for growing a variety of vegetables or a variety of tropical plants, etc. must maintain a relatively high temperature of the temperature absolutely required for the growth of the plant. In particular, in winter, when the outside temperature drops sharply, a separate heating device such as a boiler or a hot air fan must be used to supply relatively high temperature air in the house to maintain the inside of the house at a constant temperature.

The heating device has been proposed in various ways according to the type of fuel used or the method of heat exchange, and is still widely used. Especially, in a place where a relatively large room is heated, such as a plastic house, it is a so-called hot air heater mainly using warm air to heat the room. It is done forever.

Heaters using warm air are most widely used because they can force forced air blowing in the entire room within a relatively short time, which is heat-exchanged. Looking at the conventionally proposed warm air heater as an example, this is disclosed in Korean Laid-Open Patent Publication No. Japanese Patent Application Laid-Open No. 1990-0069698.

The invention of the first application is an air intake means for sucking external air and indoor air, heat exchange means for warming the air sucked by the air intake means by indirect contact with the combustion heat, a burner for supplying combustion heat to the heat exchange means, heat exchange And a blowing means for blowing air heated in the means into the house.

That is, the heat source generated by burning fuel such as gas, oil, etc. with a burner is heat exchanged with heat exchange means consisting of a plurality of heat exchange pipes in the heat exchange chamber, and the outside air passes through the heat exchange pipe by the air suction means. It is configured to be heated during the heat exchange and then blow into the inside of the plastic house.

However, such a conventional warm air heater has a structure that focuses on maximizing the heat exchange area between the heat source of the burner and the air to be blown, so the structure is complicated and the manufacturing cost is not good due to poor fabrication and assembly. have.

That is, since the structure of the heat exchange method according to the heat exchange is complicated, it is difficult and difficult to manufacture the heat exchanger, so that the manufacturing cost is increased, and the heating efficiency is significantly reduced by the complicated heat exchange method.

In addition, since the energy source is configured to use gas or oil, the cost required for combustion is increased, which is not economical, and there is a serious problem in noise generated from burners and blowers.

In addition to this configuration, there have been several proposals for warm air heaters that use coal or lignite (hereinafter referred to as "solid fuel") as an energy source without using gas or oil. Accordingly, there is a problem that it is difficult to obtain the expected heating efficiency due to lack of heat.

Since the conventional hot air heaters supply and burn solid fuel in one combustion space at the same time, combustion efficiency is lowered, and thermal waste is so severe that heat release, that is, thermal efficiency is lowered compared to the fuel consumption, and complete combustion is not achieved. If the air is injected at high pressure for the complete combustion, the solid fuel that is burned in the combustion chamber, ie, coal or lignite, is melted and slag, resulting in difficulty in post-treatment. .

The present invention is invented to solve the above problems, the object is to provide a plurality of combustion tanks in the warm air base to allow the fuel to be burned in the combustion tank to maximize the heat generation efficiency with a small amount of fuel consumption In addition, the present invention provides a hot air fan that can induce complete combustion, as well as simplify and facilitate the treatment of the burned ash and the fuel supply to the fuel tank.

In addition, the hot air heater of the present invention selectively fires all or part of a plurality of combustion tanks provided in the warm air main body to control the temperature and greenhouse of the greenhouse according to the day, night, spring, summer, autumn and winter seasons of the temperature difference occurs It is to provide a warm air fan to properly control the temperature management according to the area.
