Title: Vaporizer
Inventor: TSUDA TSUTOMU
IPC: F23D11/44
Filed: 1991-04-10
Abstract: PURPOSE:To make a vaporizer effective for starting the combustion in a shortened time and for reducing the power consumption. CONSTITUTION:In a kerosene heater with a built-in fan, immediately following the start of the operation, a heat-recovering part 10 is held apart from a vaporizing part 20. Therefore, an electric heater 40 applies its heating to only the vaporizing part 20, which consequently is heated up in a short time to a specific point at which kerosene can be vaporized continuously. This heating of the vaporizing part 20 to the specific point is detected and thereupon a solenoid 30 is energized so that the excitation pulls the heat-recovering part 10 from a state of separation to a state of tight contact with the vaporizing part 20. Then an oil-transfer pump 60 is actuated to send kerosene from an oil tank 50, through an oil-feeding pipe 70, and to the vaporizing part 20, which converts the kerosene into a gas, jets the gas from a nozzle 80, and sends its mixture with air to a combustion part 90 to burn it. The flame 100 of the combustion heats up the heat-recovering part 10 so that subsequently the vaporizing part 20 is heated by heat recovered from the heat-recovering part 10 and continues to vaporize kerosene subsequently supplied.
