Abstract (en)

[origin: WO0005540A1] A hot air generating device comprises a main housing (3) which defines a hollow interior region (10). A motor driven fan (18) draws air through a main air inlet (11) at one end of the housing (3) through the hollow interior region (10) and delivers a heated air stream through a main air outlet (12) at the other end of the housing (3). A heat exchanger (15) is located in a downstream portion (8) of the housing (3) for heating air being delivered through the hollow interior region (10) by the fan (18). A combustion chamber (25) in the heat exchanger (15) houses a gas catalytic combustion element (29) which is supplied by gas/air mixture through a burner (38) and converts the gas/air mixture to heat for heating the heat exchanger (15). An upstream portion (5) of the housing (3) which forms a handle (6) houses a reservoir (30) from which fuel gas is supplied to the combustion chamber (25). Batteries (20) in the handle (6) power a motor (19) for driving the fan (18). The heat exchanger (15) completely shields the gas catalytic combustion element (29) from the affects of the air being urged through the hollow interior region (10) by the fan (18) for preventing chilling and inadvertent extinguishing of the gas catalytic combustion element (29) during use.
