PURPOSE:To obtain a smooth starting of the atomizer provided with electric vibrators comprising such as piezoelectric elements by an arrangement wherein at the starting of the atomizer, the vibrator provided in an atomizing part is operated with a certain delay after the starting operation of the vibrator provided in a deaerating part for deaerating the air solved in kerosene. CONSTITUTION:An air warmer includes the deaerating part 7 for deaerating the air contained in the kerosene fed from a kerosene feed pipe 6 and the atomizing part 12 supplied with thus deaerated kerosene by a pump 10 through a feed pipe 11. The atomizing part 12, under the operation of the first electric vibrator 37 comprising a disc-shaped piezoelectric element 35 and a vibration plate 36, compresses the kerosene in a compressor chamber 27 and atomizes and jets the same through a nozzle part 31. The deaerating part 7, under the operation of the second electric vibrator 48 comprising a piezoelectric element 47, separates the air solved in the kerosene in the form of bubbles 49. In this instance, at the starting of the atomizer, a control is carried out so that the first vibrator 37 is started with the certain delay after the start of the second vibrator 48', thereby obtaning a smooth starting of the atomizer. |
