PROBLEM TO BE SOLVED: To provide a hot blast generation device preventing the temperature of emitted hot blast from lowering as a result that cool air is mixed with the hot blast emitted from a hot blast outlet to generate a turbulent flow. SOLUTION: This hot blast generation device is provided with a cool air passage separated from the hot blast generation passage in the outer circumferential part of the hot blast generation passage having a heating element. This device is provided with a cool air feed guide connected to the cool air passage and feeding the cool air to the outside and a hot blast feed guide connected to the hot blast generation passage and feed the hot blast to the outside. The hot blast feed guide is so formed as to be projected from the cool air feed guide. COPYRIGHT: (C)2003,JPO
