  • Patent number: 4995171
    Abstract: A gas combustion type dryer is provided wherein a liquefied gas is ignited by electric discharge and combusted to forcibly blow out heated air by a fan, while eliminating adverse effects of remaining heat after the stop of fan operation and maintaining the gas pressure constant. A temperature controller is provided together with a combustor within a blowing barrel of a dryer main body, and a pressure regulator is provided together with a liquefied gas tank within a handle. The pressure regulator is coupled to the combustor with the temperature controller interposed therebetween.
