CONSTITUTION: A hot blast heater(100) comprises an upper case(110), an atelier member(140), and a heat formation pipe(145). The atelier member is arranged in the upper case, and forms hot air by combusting the provided fuel. The heat formation pipe is arranged inside the atelier by penetrating the atelier member. The external air is flowed into a heat formation pipe and is changed into warm wind by heat formed at the atelier member. One or more portion of the heat formation pipe is bent to buffer thermal transformation of the heat formation pipe. |
