PURPOSE:To facilitate the setting of the ratio between hot air and radiation energies by means of the transmissivity of infrared rays through a heating pipe by drafting air to the heating pipe to generate hot air which is discharged from a grill, and also radiating the light and infrared rays from the heating pipe from the grill to the front space. CONSTITUTION:The radiation electric fan heater has a radiation heater 1 which has a heater element 2 that is supported in a heat-resistant pipe 4 and is thermally insulated, and said high-temperature radiation heater 1 is enclosed by a grill 7 in the front that comprises multiple thin plates and a reflector 6 in the back. A wind-tunnel unit 10 consists of side plates 8, 9. When air is drafted to the pipe 4 which is heated by the heater element 2, it is heated to become hot air and discharged through the grill 7 to the front space. The light and infrared rays from the heater element 2 pass through the pipe 4, and are radiated through the grill 7 to the front space directly or after being reflected by a reflector. |
