PURPOSE:To prevent the connection line from being disconnected due to deficiency in cooling and a control part from making erroneous operations caused by damages and the like of a heat generating member by providing the heat generating body at a place at least one of a hot air flow path and a combustion air flow path. CONSTITUTION:A gas combustion type hot air flow space heater 1 comprises a combustion vent path 2 which causes air introduced from the outdoor to burn and exhausts it again out of the room, a gas inlet path 3 which caries out the gas supply into the combustion vent path 2, a hot air flow passage 4 which replaces indoor air with a combustion gas in said combustion vent path 2 and again discharges as a hot air flow an electronic control device, and a main body case 8 which accommodates them. Further, a power transistor 6 for controlling the rotation which is a heat generating body is fastened to an indoor air inlet path 402 of the hot air flow vent path 4 by means of screws. Accordingly, since the power transistor 6 for controlling the rotation is cooled by a blower 403 for the hot air flow, it is made possible to prevent the heat generating body from generating heat beyond necessity. |
