気の流出が効率良く行なわれる。First, among the hot air that accompanies the combustion of vaporized fuel by the burner (4), the extra hot air that is released into the main body (1) as radiant energy from the pot (5) and combustion tube (6) is released into the main body (1). It rises to the top and opens the hole B (lob
) to the outside of the main body (1). Along with this, external air flows in through the opening B (10b). This allows air to flow inside the main body (1) through the opening A (1
The air flowing into the main body (11) from 0a) absorbs the hot air of radiant energy, and the explanation will be omitted since the control board is shown. 9) Excess hot air from the surrounding area is discharged to the outside of the main body (1) to prevent thermal deterioration of electronic components.In particular, the rotation of the blower fan (7) causes air near the air intake port (2) to flow into the main body (1). 1) Since hot air is taken inside, hot air can efficiently flow out from the opening B (10bl) located near the air intake port (2).

けで設置できるため、製造が簡単である。[Effects of the Invention] As described above, in the hot air heater according to the present invention, air is taken in through the first opening, and excess hot air around the control board flows out through the second opening through the air path. Therefore, when the 1m air heater is working, the control board is automatically cooled by the wind, which reliably prevents malfunctions due to thermal deterioration of the control board, improving safety, and preventing internal heating due to the rotation of the blower fan. Since the heat removed by cooling the control board is reused by diverting the hot air from the second hole to flow out the second hole, more efficient hot air flow is possible. Manufacturing is simple because the first and second openings can be installed by simply machining the external panel of the 9 body.
