Abstract

This invention relates to a blower nozzle adapted to fit onto a hand dryer for drying human hair wherein the blower nozzle has a plurality of apertures along a side thereof for allowing gas to escape and has a restricted mouth. In this invention adjustable closure means are provided internally of said nozzle, which, when turned in one direction, allows free flow of heated air through the nozzle and when turned in another direction diverts a portion of the air away from the nozzle mouth and to and through apertures in the side of the nozzle. In a preferred embodiment of my invention the apertures are distorted so that air passing through the apertures is given a direction generally parallel to the axis of the nozzle instead of a direction generally normal to the axis of the nozzle.

Claims

1. A blower nozzle adapted to fit on a hand dryer for hair, comprising a cylindrical portion connected to the outlet of said hand dryer, a nozzle portion connected to said cylindrical portion and having converging opposite side walls terminating in a restricted opening, a plurality of apertures in at least one of said converging side walls for permitting air from said dryer to pass out of said apertures at an angle to the axis of said nozzle, and adjustable vane-type closure means movable from a position where it covers said apertures to a position where it projects into the stream of air passing through the nozzle to direct said air stream through said apertures.

2. Apparatus as described in claim 1 wherein said closure means when in the diverting position, diverts at least 20 percent of the air passing through said nozzle so as to pass through said apertures.

3. Apparatus as described in claim 1 wherein said closure means when in the diverting position diverts less than 35 percent of the air passing through said nozzle so as to pass through said apertures.

4. A blower nozzle as described in claim 1 wherein said closure means is capable of closing said apertures substantially completely.

5. A blower nozzle as described in claim 1 comprising stopping means for allowing incremental adjustment of said vane-type closure means to allow it to be at various intermediate positions between the open and the closed positions.

6. Apparatus as described in claim 1 wherein portions of said side wall in the region of said apertures are distorted so as to produce a forward flow of air greater than 20* and less than 45* to the axis of said nozzle.
