Description

Hot air blower using microwaves {THE HOT AIR BLOWER USING MICROWAVE}

The present invention relates to a hot air fan, and more particularly, to a hot air fan using a microwave for generating hot air using a heating element generated by a microwave.

A hot air fan refers to a device for generating hot air, that is, hot wind. In general, a hot air fan includes a combustion chamber having a fossil fuel such as kerosene or light oil as a fuel source, and burns the fuel by using a burner in the combustion chamber. It has a configuration for generating hot air.

As described above, in the case of a conventional hot air fan using fossil fuel such as kerosene or diesel, the operating cost increases due to the high oil price, and maintenance of the combustion chamber and the devices related to the combustion chamber is not easy.

In particular, the generation of carbon dioxide and other harmful gases that are generated when diesel or kerosene is burned cannot be avoided, which acts as a cause of environmental pollution.

Accordingly, in order to solve this problem, a hot air fan equipped with a magnetron has been proposed through the Utility Model Registration No. 0265351.

Is provided with an inlet (12a), a blower fan (6) for discharging the hot air to the outside on one side opposite to one side is provided, the outlet (12b) of the fluid 11 close to the blower fan (6) on the other side The provided hot tub (2), associated with the inlet and outlets (12a, 12b) from the outside of the hot tub (2) and a drive motor (8) for pumping the fluid (11) into the hot tub (2) in the vicinity of the inlet (12a) A plurality of chambers 4 and a plurality of chambers 7 each having a magnetron 3 for heating the fluid 11 are provided in the main pipe line 7 and the heat pipe 2 in the vicinity of the inlet 12a. A plurality of conduits 10 provided in the interior of the four chambers 4 and associated with the main conduit 7 via an inlet 12a, one end of which is associated with a plurality of conduits 10, the other end of which is an outlet It is connected to the main pipe line (7) through (12b) provides a hot air fan equipped with a magnetron, characterized in that it comprises a radiator (9) for heating the outside air sucked in the suction fan (5).

According to such a conventional hot air fan, a path through which a fluid circulates is established, a primary heating section including a magnetron is formed on the path, and a radiator is configured to heat the fluid passing through the primary heating section secondly, Is first heated, and then circulated while being heated by the radiator for the second time, and the air is passed along the periphery thereof to be heated and blown to the outside.

While passing through the conduit 10, the microwaves are irradiated into the chamber 3 by the magnetron 3 configured in the chamber 4, and the fluid flowing through the conduit 10 is directly heated by the microwaves thus irradiated.

The fluid 11 heated by the magnetron 3 and heated in the chamber 4 passes through the conduit 10, and then is sent to the radiator 9, which is secondarily heated by the radiator 9.

Therefore, the outside air that has undergone the first endothermic process from the periphery of the chamber 4 is sent to the periphery of the radiator 9 so that the second endothermic process occurs. 6) is discharged to the outside of the heat container (2).

As described above, since the external air is heated by heating the fluid 11 using the magnetron 3 and heating the heated fluid 11, there is no generation of carbon dioxide and noxious gases, and the like. It is very easy to maintain, and even if used for a long time, the same high thermal efficiency as the initial use can be obtained.

However, according to such a structure, even though the structure is used for agriculture that requires relatively low temperature, only the magnetron is used to obtain the required temperature, and thus, a radiator for secondary heating cannot be configured.

Therefore, in addition to the power for driving the magnetron, additional power for operating the radiator is required.

In view of the above, the present invention provides a heat source having a high-efficiency heat source sufficient to provide hot air by generating a heat generating element that reacts with microwaves, and heats the air by the provided heat to generate hot air without generating harmful gas and pollution gas. It is to provide a hot air fan using a microwave to provide.
