Abstract

A dryer comprising a housing in which there is a hollow space which is accessible from outside through a housing port and which serves to accommodate extremities, more particularly hands, to be dried by means of a current of air, and in which a device for generating the current of air is present. The dryer also includes a means for reducing germs in the current of air, such as a plasma or ion source, or a radiation source such as UV emitter or dielectric barrier discharge lamp.

Claims

1. A dryer comprising a housing, in which there is a hollow space which is accessible from outside through a housing port and which serves to accommodate extremities, more particularly hands, to be dried by means of a current of air, and in which a device for generating said current of air is present, the dryer further including a means for the reduction of germs in said current of air.

2. The dryer as defined in claim 1, wherein said means for the reduction of germs is selected from the group consisting of

a device for dispensing a germ reducing substance into said current of air,

a source of plasma or ions, and

a source of radiation.

3. The dryer as defined in claim 2, wherein said germ reducing substance is liquid or gaseous and is more particularly selected from the group consisting of

at least one alcohol or alcoholic solution and

a gas containing ozone and/or free radicals.

4. The dryer as defined in claim 2, wherein said source of plasma or ions is a source of plasma or ions that is stimulated by microwaves or radio frequencies.

5. The dryer as defined in claim 2, wherein said source of radiation is a UV emitter or a dielectric barrier discharge lamp.

6. The dryer as defined in claim 1, wherein it comprises at least one exhaust duct and at least one air supply duct, which communicate with said hollow space such that said current of air is capable of being circulated through said exhaust duct, said air supply duct, and said hollow space.

7. The dryer as defined in claim 6, wherein said device for generating said current of air is disposed in said exhaust duct, in said air supply duct, or in the region of said hollow space and is more particularly disposed in the region of said exhaust duct.

8. The dryer as defined in claim 6, wherein said means for the reduction of germs is disposed in said exhaust duct, in said air supply duct, or in the region of said hollow space and is more particularly disposed in the region of said exhaust duct.

9. The dryer as defined in claim 1, wherein the port area of said housing port is less than 20% of the total surface area of said hollow space.

10. The dryer as defined in claim 1, wherein the total surface area of said hollow space is enclosed by said housing to an extent of more than 25%, preferably more than 35% and more preferably more than 50%.

11. The dryer as defined in claim 1, wherein said current of air is blown into said hollow space through at least one nozzle, more particularly through two flat nozzles disposed opposite each other at the longitudinal side walls of said housing port, wherein the angle of inclination (α

) between the nozzle orifice and the port area of said housing port is preferably at least 7°
