う問題がある。Problems to be Solved by the Invention However, such a fan heater box 1
In this fixed configuration, as shown in FIG. 4, a phenomenon often occurs in which hot air leaks from a small gap between the contact area between the front and rear side wall flanges 1a of the fan heater box 1 and the upper surface 5 of the heating chamber. Also,
This gap may become even larger due to thermal distortion of the upper surface 5 of the heating chamber at high temperatures. In this way, if hot air leaks, the atmospheric temperature within the heating chamber 2 may not rise enough, the electrical components inside the device may become abnormally heated due to the leaked hot air, or resin components may become thermally deformed or discolored. In addition, there is a problem that the temperature of the outer frame of the heating device rises so much that people may get burnt if they touch it with their hands.

特にパテ塗布をした場合、修理等の目的で分解す
ることが非常に困難であるという問題があつた。 For this reason, conventionally, it was necessary to apply high-temperature heat-resistant putty to the front and rear side wall flanges 1a of the fan heater box 1 and to fasten them to the heating chamber top surface 5 with screws 4. In order to prevent the tips of the screws 4 from popping out, the screws 4 must be tightened from inside the heating chamber 2, which significantly impairs the workability.
Particularly when putty was applied, there was a problem in that it was very difficult to disassemble for the purpose of repair or the like.

にでき実用上きわめて有利なものである。Effects of the Invention As described above, in the heating device of the present invention, when installing a fan heater box that increases the atmospheric temperature in the heating chamber, the L-shaped metal fitting that runs substantially closely along the inside of the side wall of the fan heater box is installed. It is attached to the top of the heating chamber by spot welding, etc.
Therefore, even if a part of the fan heater box is not fixed with putty or screws, the hot air from the fan heater box will not leak outside.
This improves the efficiency of raising the temperature of the atmosphere in the heating chamber, prevents abnormal temperature rises, thermal deformation, and thermal discoloration of parts inside the heating device due to heat, improves safety, and is greatly useful for improving workability. In particular, in the present invention, one surface of the L-shaped metal fitting is provided so as to be in contact with the top surface of the heating chamber, and the other surface is provided along the inside of the side wall of the fan heater box, thereby preventing thermal deformation of the top surface of the heating chamber. However, this prevents contact between the fan and the top surface of the heating chamber, so the distance between the fan and the top surface of the heating chamber can be reduced, and the fan heater box can also be made smaller, resulting in smaller equipment and improved thermal efficiency. Can be achieved together. Furthermore, the fan heater box can be easily positioned when it is installed, which is extremely advantageous in practice.
