Title: Oil stove
Inventor: ASANO YOSHIO
IPC: F23N5/02
Filed: 1981-12-16
Abstract: PURPOSE:To reduce the offensive smell given off when the fire of oil stove is put out by an arrangement wherein a combustion air supplying fan installed in the combustion unit which discharges exhaust gas in the room to be heated is driven for a predetermined time after the fire of the stove is put out. CONSTITUTION:When putting out fire of the stove, a lever 4 is released to lower wick 3 to put off fire. Since the fire put-off operation is made by changing over the operating switch from a position (a)-(c) another position to (a)-(b), a fan motor 17a is energized with an electric power through a closed temperature switch 26 and a change-over contact 38a of a relay 38 occupying a position (d)- (e). Thus, if the combustion air is supplied by the fan motor 17a when fire is put out, the oil vapor filled in a fire pan 10 is burnt by the combustion air. By this arrangement, it is possible to prevent the generation of offensive smell when the fire of the stove is put out.
