<p>PROBLEM TO BE SOLVED: To provide a codeless heat air supply apparatus to prevent flame from injection to an external part and prevent the occurrence of a problem, such as clogging of an orifice in a short time. SOLUTION: This codeless heat air supply apparatus comprises an injection valve 14 to inject LPG; an LPG tank 13 having a nozzle valve 15 used both as an opening and closing mechanism for LPG and a regulation mechanism; a piezoelectric element for ignition utilized for ignition; a blower 3 used both for supply of air necessary to combustion and supply of a large amount of hot air; a catalyst combustion chamber 7 where a flame combustion chamber 11 and a combustion catalyst 5 are arranged; and a double layer disc having the proper number of combustion air ports 8 to guide air to the combustion chamber. This heat air supply apparatus is formed such that even when an air supply amount is changed, an amount of air necessary to combustion is ensured at a constant value. Further, a combustion point is automatically transferred from flame to a combustion catalyst by a blower turned ON/OFF through operation of a bimetal switch 9 to detect the heat of the combustion chamber. A battery, an LPG tank, a blower, and a combustion catalyst wherein refractory stainless forms a carrier are contained in one casing to form an integral one-piece.</p> |
