構成したことを特徴とする温風発生装置。 PTC thermistors as a heat source with electrodes facing perpendicular to the wind direction are stacked in series in two or more stages in the air passage, and power is applied to each thermistor in sequence to generate a predetermined hot air output. In hot air generators, when hot air output increases, power is turned on in order from the thermistor on the windward side, and when hot air decreases, power is turned off in order from the thermistor on the leeward side. A hot air generator characterized by comprising a switch circuit for turning on the power.
