Abstract

A hot air generating tool, comprising a tubular body (11) for aspirating and discharging drying air, with which means for heating the air and a handle (12) are associated. The air heating means are constituted by a Ranque-Hilsch vortex tube device (13) supplied with compressed air.

Claims

AMENDED CLAIMS received by the International Bureau on 15 June 2009 (15.06.2009)
1. A hot air generating tool, comprising a tubular body (11) for aspirating and discharging drying air, with which means for heating said air and a handle (12) are associated, said air heating means being constituted by a Ranque-Hilsch vortex tube device (13) supplied with compressed air, characterized in that said Ranque-Hilsch vortex tube device (13) is integrated in said handle (12).
2. The tool according to claim 1, characterized in that said vortex tube device (13) comprises a cylindrical chamber (14), in which compressed air is injected in a radial direction from a lateral port (15), a first cylindrical tubular element (16) for feeding hot air protruding from said chamber (14) coaxially thereto on one side, a second tubular element (17) which is shorter than the first one (16), for emitting cold air, protruding coaxially from said chamber coaxially thereto at the other side, a valve (18) for adjusting the flow-rate of pressurized hot air being provided at the end of said first tube (16).
3. The tool according to one or more the preceding claims, characterized in that said first tube (16) passes through said handle and leads into said tubular body (11) for aspirating and discharging air.
4. The tool according to one or more of the preceding claims, characterized in that said tubular body (11) comprises a first central part (20), with which the handle (12) is jointly connected, a second intake part (21), with a frustum-shaped internal surface (22) which tapers toward the inside of the tubular body (11), and a third discharge part (24), with an outer portion (25) which diverges to provide a Venturi effect.
5. The tool according to claim 4, characterized in that said third part (24) is screwed to said first part by means of two corresponding threaded portions, an internal thread (26) being provided on said first part (20) and a complementary external thread (27) being provided on said third part (24), to adjust the temperature by increasing or decreasing the Venturi effect.
