PURPOSE:To make a substantial complete prevention of occurrence of bad odor when the flame is diminished by a method wherein an inside part of a partition plate 5 is made as a wick storing chamber A and an oil tank 1 is made as a suction gas cooling chamber B. CONSTITUTION:A combustion wick 3 is descended and at the same time a suction pump 6 is drive for a specified period of time, resulting in that a wick storing chamber A shows a high negative pressure to cause the air in the burner 2 to be sucked through the upper end part of the combustion wick 3. When the air discharged from the sucking pump 6 is fed to the oil tank 1, the oil tank 1 shows a low temperature and the fuel is present at the bottom part of the tank and the inner wall surface is wet with fuel, so that the fuel gas contained in the air is easily condensed to decrease a discharging volume. When a thermal radiation plate 9 is fixed to the sucking part 7 or discharging part 8 of the sucking pump 6, the hot temperature gas to be sucked is cooled and if the fuel gas is condensed by the suction gas cooling chamber B, an amount of air discharged from the oil tank 1 is reduced and so it may sufficiently be discharged through the air hole 17 made at a receiving pan 16 in the tank 1 where the lowest temperature is found. |
