PURPOSE:To make it possible to mount a heater easily and protect said heater from damage by mounting a heater to heat a decoration panel to the inner wall of a ventilation flue. CONSTITUTION:This comprises a seal section 11 which faces indoor walls, such as a blowoff grille 10 and ceilings, a ventilation flue 13 formed inside the blowoff grille 10, a projected part 14 installed on the way of the ventilation flue, and a bedewing preventative heater 15 which uses a sheath heater. This heater is installed at the depth of the inner wall of a ventilation case and the projected part 14 so that it may wind up the inner side of the ventilation flue 13 with aluminum tape 16 by two turns. The heater is installed to such an area which is formed by an insulation material 17 mounted to cover the heater 15, a blowoff port 18 of the blowoff grille, a decorative panel 19 which closes the opening of the indoor equipment 12 and a spot mostly subjected to the condensation of dews. This blowoff port 10 is mounted to a mounting section 23 of a lower part of a blowoff chamber. |
