Preferably, the diameter of the first hollow 12 is larger than the diameter of the second hollow 14 in order to increase the air volume. In this embodiment, four second holes 14 are installed at intervals of 90 degrees, but four are formed. In this case, the far-infrared radiation core 10 may be formed with a plurality of heat dissipation holes 16 to reduce the installation weight and reduce the manufacturing cost and increase heat dissipation. In this embodiment, the heat dissipation hole 16 is formed in the longitudinal direction of the far infrared radiation core 10, but is not limited to this direction.

The core heater 20 is provided in the first hollow 12 at the rear side of the far-infrared radiation core 10. At this time, the core heater 20 is supported and fixed to the support plates 60 and 62. At this time, the support plates 60 and 62 are interconnected and restrained by bolts 66.

In the case of automatic mode selection, the room temperature of the house or house is measured as in FIG. 4 (S10).

Next, the measured room temperature and the set temperature (optimum temperature of the cultivated plant or barn) are compared (S11). When the room temperature is lower than the set temperature, the air heater 20 and the core heater 20 are operated (S12), and at the same time, the blower 40 and the air compressor 50 are operated (S13).

Therefore, the heat heated by the hot wire 24 on the air heater 20 side is discharged through the first hollow 12 of the far-infrared radiation core 10 by the blowing force of the blower 40. At this time, the heated warm air passing through the first hollow 12 is discharged while heating the far-infrared radiation core 10.

On the other hand, the air compressed from the air compressor 50 is heated while passing through the air heater 30 is discharged to the second hollow 14 at a high temperature. Therefore, the far-infrared radiation core 10 forming the second hollow 14 is heated to a high temperature to increase the amount of far-infrared radiation.

Instantaneous heat transfer allows rapid heating and three-dimensional heating effects are achieved due to far-infrared wavelengths.

On the other hand, when the measured temperature is higher than the set temperature in the comparison determination step (S11) of the measurement temperature and the set temperature, the air heater 20 and the core heater 20 are stopped (S14, 15).

As such, the automatic mode automatically adjusts the temperature of the measurement room to continuously supply hot air and far-infrared heat.

On the other hand, in the manual mode selection, the operation of the air heater 20 and the core heater 20 are simultaneously controlled by the on / off operation of the pushbutton 107.

Since the warm air heater 1 of the present invention configured as described above is compactly configured, it can be freely installed in a ceiling, a wall, a corner, and the like regardless of the size of the vinyl house, greenhouse, or barn.

In addition, by using the air heater 30, short prevention is possible, insulation coating is unnecessary, strong against humidity, and no rust is generated, thereby improving service life.

In addition, even when the core heater 20 and the air heater 30 are electrically turned off, the remaining heat is accumulated in the far-infrared radiation core 10 to continuously radiate the far-infrared radiation, thereby promoting the growth of plants and livestock. This is improved.

Thus, the warm air fan 1 of the present invention not only supplies the warm air but also forms the far-infrared wavelengths of various angles on the entire surface, and convections natural pure wind in the room, so that the heating is smooth and the pests can be eliminated throughout the entire area. And promote the growth of plants and livestock. In addition, the hot air heater 10 may be replaced with high oil prices due to high electrical efficiency.

In this embodiment, the core heater 20 is configured to have a length corresponding to the width of the far infrared radiation core 20 and the back plate 60,62 apart from the width, the present invention, if necessary, the core heater 20 It can also be configured with the above length.

On the other hand, the warm air fan 1 may form a friction protrusion 14a to increase the coefficient of friction of the warm air flowing out of the air heater 30 in the second hollow 14 as shown in FIG.

In addition, the far-infrared radiation core 10 may be configured by adding a radiation core heater 15 around the first hollow 12. In this case, the radiating core heater 15 may be operated separately from the core heater 20 to remove odor generated in a humid state such as summer by the emission of far infrared rays radiated from the far infrared radiating core 10.

In addition, a plurality of quartz tube heating elements 80 may be further installed between the far-infrared radiation core 10 and the core heater 20. At this time, the heating tube heating elements 80 may be arranged in a linear or circular or lattice form in the heating element case (90). The quartz tube heating element 80 is composed of a cylindrical quartz tube 80a and a resistance heating layer 80b applied to the outer surface between both terminal portions of the quartz tube 80a by powder alloy material. As the alloy material of the resistive heating layer 80b, iron, tin, silicon, manganese, barium, tungsten, molybdenum, and the like are alloyed at a predetermined ratio. The resistive heating layer 80b may be applied using a conventional deposition method, a spray method, or a screen printing method.
