開ける。FIG. 4 shows a time chart of the conventional operation method of the hot air heater. The vaporization heater and the oil feed pump are stopped by starting the fire extinguishing operation. A few seconds after that, the warm air blower is suddenly stopped by half-wave control. This is to prevent the unburned gas after extinguishing from ejecting to the outside. Then, the current flame resistance value (frame level) is detected by the flame detection device, and if the flame resistance value exceeds the set value, the fuel injection valve is closed and the fuel gas remaining inside the vaporizer is ejected. Prevent from doing. After that, the blower is started for a certain period of time, and the blow prevents the temperature from rising due to residual heat inside the warm air heater. When the temperature of the carburetor decreases, unburned gas does not jet from the jet valve, so the jet valve is opened after a few minutes.

作制御手段を備えている。<Means for Solving the Problems> In order to achieve the above object, the hot air heater according to the present invention heats and vaporizes the fuel fed by the oil feeding pump in the vaporizer, and the vaporized gas is burned through a valve to a burner. In a hot-air heater with a structure in which the vaporized gas is ejected into the burner and the vaporized gas is ignited by energizing the ignition heater arranged in the burner, the energization of the oil feed pump is stopped at the same time when the fire extinguishing operation is started, and the ignition is performed. When the heater is turned on and the time t1 is reached after a lapse of a certain time from the start of the fire extinguishing operation, the valve is closed, and after the valve is closed, it is longer than the above certain time from the start of the fire extinguishing operation. A fire extinguishing operation control means is provided for stopping energization of the ignition heater at a time point t2 when a predetermined time has elapsed.

When the time t1 has been reached after a certain time has passed from the start of the fire extinguishing operation, the valve is closed, and after the valve has been closed, the time t2 has been reached when a predetermined time longer than the given time has elapsed from the start of the fire extinguishing operation. Since the extinguishing operation control means for stopping the energization to the ignition heater at a time point is provided, the unburned gas remaining in the carburetor is burned by the ignition heater, and thereafter, before the energization to the ignition heater is stopped. The valve is closed to prevent unnecessary fuel supply from the carburetor to the burner, and when extinguishing fire without burning unburned gas in the ignition heater more than necessary.
It is possible to reliably prevent the generation of a foul odor when extinguishing a fire and shorten the fire extinguishing time.
