BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave regenerative hot air fan, and more particularly, to a microwave regenerative hot air fan capable of exhibiting the most efficient energy efficiency by mixing hot air heated by passing through a microwave heat exchanger with outdoor air to supply hot air.

Generally, a hot air fan is a device that burns electric energy or fossil fuel, warms the fluid with the heat, and applies pressure to supply it to a desired place.

Hot air can generate hot air by using electric energy in a small space, but it is almost impossible to use electric energy in a place where the space is very large, such as an industrial use or a gymnasium. The reason is that electric energy is very expensive as advanced energy. In addition, in the case of a hot air blower using electric energy, the problem of not being able to quickly heat the fluid is also included.

Therefore, when hot air is required at a large capacity, it is common to employ a hot air blower that burns fossil fuel. Fossil fuel heaters have the advantage of being very convenient to use because they can heat fluids faster than hot air blowers that use electrical energy. However, fossil fuel-based heaters pollute the environment as is well known. In addition, as the price of crude oil, which is a representative fossil fuel, rises, the price per calorie increases, resulting in a cost increase to the user.

A microwave heat storage boiler filed by the applicant of the present invention is registered and known in Korean Patent Registration No. 10-1060709. The conventional microwave heat storage boiler is a boiler which uses a microwave oscillator to heat the heating material and store the heat source by using a heat storage material, and to prevent the temperature rise in the extreme area by installing an air circulation means in the boiler. The boiler using such a microwave oscillator is a boiler using water as a medium which is supposed to operate by circulating warm water.

The above objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, a micro regenerative hot air blower according to a first preferred embodiment of the present invention includes a microwave emitter 30, a heating material 50 heated by the microwave emitter 30, 50), and a mixer (80) for mixing the gas heated by the flow path structure with the outside air to increase the volume while the temperature is lowered.

Here, a vortex fan 70 is provided in the heating material 50 to facilitate rapid heat exchange of gas. The vortex fans 70 are configured such that a plurality of vortex fans 70 are connected together by a single shaft 71 and rotated together. In addition, a heat storage material may be additionally provided inside the heating material 50.

The flow path structure includes an inflow pipe 61 through which the outside air is introduced by the fan 59, a lower reservoir 60a in which the introduced outside air is temporarily stored and mixed, and a gas of the lower reservoir 60a is divided An upper reservoir 60b for temporarily storing and mixing the gas transferred through the branch pipe 60 and a gas heated from the lower reservoir 60a, And a gas introduced into the inflow pipe 61 is reciprocated between the upper and lower reservoirs 60a and 60b through the branch pipe 60 several times.

A central temperature sensor 201 is provided in the heating material 50.

The exhaust pipe 62 is provided with an exhaust temperature sensor 202 for sensing the temperature of exhausted gas.

The discharge port (81) of the mixer (80) is provided with a warm air temperature sensor (203) to control the amount of warm air discharged.

An outer housing 10 is provided on the outer side of the housing 10 and an exhaust port provided with an exhaust fan 40 is provided on the housing 10.

Between the exhaust port of the housing 10 and the mixer 80, bypass pipes 100 and 101 are installed to supply the gas exhausted from the exhaust port of the housing 10 to the mixer 80.

The bypass pipes 100 and 101 are provided with an exhaust port 101a for discharging the gas to be delivered to the outside and a valve 103 for selectively controlling the transported gas by the exhaust port 101a or the mixer 80 .

The microwave emitter 30 is installed inside the outer housing 10 and inside the inner housing 20 and receives microwave power to radiate the microwave to the heating material 50. The microwave diverter 30 is normally controlled so as to radiate microwaves at regular intervals without continuously emitting microwaves. This is to prevent the heating material 50 from overheating to a too high temperature. This is because it is a characteristic of heating by microwave. Because of these characteristics, boiler or hot air blower using microwave has not been commercialized until recently.

The housing 10 and 20 are formed of inner and outer housings and the inner housing 20 provided inside the microwave emitter 30 is formed to have a function of preventing the electromagnetic wave emitted from the microwave emitter 30 from leaking to the outside Must be sealed.

A heating material 50 is installed inside the microwave emitter 30. The heating material 50 is a constituent that is heated by microwaves. Of course, it can be made of various materials.

A gas flow path is formed in the heating material (50) so as to perform heat exchange with the heating material (50).

The flow path structure is composed of an inlet pipe 61, upper and lower reservoirs 60a and 60b, a branch pipe 60 and a discharge pipe 62, as described above. The inflow pipe (61) is a passage through which the outside air flows. The gas that has entered the inlet pipe 61 first stays in the lower reservoir 60a.

The upper and lower reservoirs 60a and 60b double the heat exchange efficiency of the flowing fluid. When the branch pipes 60 are sequentially formed from the inflow pipe 61 to the discharge pipe 62, the heat exchange is continued and the outside air is exhausted. However, since it is difficult to satisfy the target thermal efficiency, the reservoirs 60a and 60b are installed so that a part of the gas flowing through the flow path is mixed with the gas pushed later.

Since the temperature inside the heating material 50 is usually controlled in a constant temperature range, it is not always maintained at the same temperature. However, since a part of the gas flowing through the upper and lower reservoirs 60a and 60b is partially mixed with the gas before and after the gas, the temperature of the discharged gas maintains a more uniform temperature. As a result, the thermal efficiency can be further increased.

The gas that has entered the inflow pipe 61 is mixed and stored partially and temporally with the upper and lower reservoirs 60a and 60b blowing into the reservoir 60a and 60b several times.

The branch pipe (60) is divided into upper and lower spaces inside the heating material (50). The branch pipes 60 are arranged along the cylindrical space so that a space is formed at the center. And the vortex fan 70 is installed in the center space.

The vortex fan 70 stirs the heat source inside the heating material 50 to exhibit a maximally uniform temperature distribution. Since the rotation of the vortex fan 70 is also an energy source, the friction energy doubles the heat source.

A central temperature sensor 201 is installed in the heating material 50 and the operation of the microwave emitter 50 is controlled according to the sensed temperature.

An exhaust temperature sensor 202 is provided at an end of the exhaust pipe 62. Thus, the temperature of the gas exhausted to the discharge pipe 202 is known, and the driving of the vortex fan 70 can be more accurately controlled together with the central temperature sensor 201 based on the temperature. That is, if the temperature of the central temperature sensor 201 is higher than the reference temperature but the temperature of the exhaust temperature sensor 202 is detected to be lower, the rotation speed of the vortex fan 70 is further increased, .

The discharge pipe 62 is connected to the mixer 80 through a connecting pipe 63. The warmed gas transferred to the connecting pipe 63 enters the mixer 80, and the mixer 80 introduces the outside air again to increase the volume and lower the temperature to the room.

This is because the temperature of the air heated by the microwave is extremely high for directly supplying the indoor air to the room. By mixing such a high-temperature gas and the outside air, the volume of the hot air eventually becomes large.

The fan 90 of the mixer 80 is controlled in accordance with the information sensed by the hot air temperature sensor 203 installed at the outlet 81 of the mixer 80. That is, when the temperature of the hot air produced through the discharge pipe 62 is high, the number of rotations is increased to mix a large amount of outside air, while in the opposite case, the number of rotations is reduced to maintain the temperature.

By controlling these temperature sensors 201-203, hot air can be optimally produced by using the most suitable power source.

A plurality of exhaust ports are formed in the upper portion of the housing 10. An exhaust fan (40) is provided in each of the exhaust ports. This structure is intended to prevent overheating of the inside of the housing 10.

The bypass pipes 100 and 101 are connected from the exhaust port of the housing 10 to the mixer 80. The exhaust pipes 101a are provided in the bypass pipes 100 and 101 and the gas is delivered to the exhaust or mixer 80 by the valve 103. The structure of the bypass pipe (100, 101) allows the heat source that can be discharged to the outside to be recycled again.

The valve 103 is controlled to operate in accordance with the temperature information sensed by the central temperature sensor 201.

On the other hand, a second embodiment according to the present invention is shown in Fig. As shown in the figure, a heat exchanger (303) is provided between the discharge pipe (62) and the mixer (80) and the connection pipe (63) The fruit can use water or other materials that are excellent for heat exchange. The heat is accumulated by the pump 301 flowing between the tank 300 and the heat exchanger 303.

FIG. 3 shows a third embodiment according to another embodiment of the present invention. As shown in the drawing, a humidifier is provided between the discharge pipe 62 and the mixer 80. A drain hole 63a is formed in the connection pipe 63 and a container 400 is installed under the drain hole 63a and the water of the container 400 is transferred to the pump 401, The water injected into the connection pipe 63 by the nozzle 403 and condensed is circulated to the container 400 through the drain hole 63a. Of course, the moisture evaporated in the hot air is supplied to the room via the mixer 80. [ Such a structure is a structure that can be usefully used in agricultural fields that use a lot of humid air such as a vinyl house.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
