PURPOSE:To liquidize stuck soot to recover easily by increasing the temperature of the inside of a range hood by a heater while coating inner wall, a grease filter and the like by a fluororesin film. CONSTITUTION:The lower end side of each member upward, downward and slantingly arranged in a range hood body 1 provided with an intake and exhaust unit 2, a grease filter 3 and the like is curved in the form of a channel to form an oil receiving part 4, respective oil receiving parts 4 are connected in a com municating condition to form a vessellike oil recovering part 5 for the lowest part position and a heater 6 is set in the body 1 while a membrane of a fluororesin film 7 such as poly tetrafluoroethene is formed on the inner wall of the body 1, the intake and exhaust unit 2 and the grease filter 3. Thereby the temperature of the range hood body 1 is increased by the heater 6, lamp black stuck on the inner wall, the grease filter 3 and the like coated by the fluoride resin film is liquidized to flow in the oil receiving part and collected in the oil recovering part 5 of the lowest part position to recover and eliminate it. |
