ACTIVE-OXYGEN TREATMENT FOR HUMAN HEAD HAIR Oct. 16, 1962 Filed Se pt. 4, 1958 INVENTOR A ugust @u/z] United States Patent 3,058,233 ACTIVE-OXYGEN TREATMENT FOR HUMAN WAD HAIR August Guhl, Wilfried Strasse 7, Zurich, Switzerland File-d Sept. 4, 1958, Ser. No. 759,019 2 Claims. (Cl. 34-99) When drying hair, for example when washing, dyeing, bleaching or undulating same, it is known to set certain hoods on the head in order to render possible a rapid drying of the hair. Such hoods are provided with a blower and a heating element.

When bleaching, dyeing and undulating the hair of human heads, oxygen is required for bringing about an om'dation, the oxygen being mixed with steam and carried thereby to the point of application. The outflowing gaseous media propagate very obnoxious odors which are very inconvenient not only for the person being treated but also for other persons in the more or less immediate vicinity. A further inconvenience is that the air in the room or rooms is impaired with a more or less permanent efiect.

The subject matter of my present invention is a method of applying active oxygen when drying hair on the human head, and a device for carrying out such method. Said method is characterised in that active oxygen is produced directly within the range or" the point of treatment and is fed, by means of dry and warm air as carrier, to the hair to be dried. The device suitable for carrying into effect said method comprises a hood known per se, and is characterized by the fact that in said hood are arranged in sequence an electrical ozone generator, a heating element and a blower; the whole in such arrangement that the generation of oxygen, the mixing of the latter with warm air, and the feed of said air and oxygen to the points of hair treatment take place immediately above the latter within said hood.

One form of the invention is shown, by way of example, in the drawing which is a side view partly in section.

A hood 1 known per se and open at its lower end, is adjustably mounted on an articulated stand 2. The lower rim of the hood is inwardly arched at 3. On the middle portion of the hood is mounted an ozone generator 4 which functions according to the principle of quiescent discharge of which the construction per se is known. Of importance merely is that quiescent discharges occur, in contradistinction to discharges with open spark gaps. Oxygen generated by means of open spark gaps is not suited for drying hair for the purpose envisaged, since thereby is produced besides ozone a substantial amount of nitric oxide of which the presence is impermissible for hair drying. Spaced below the ozone generator and inside the hood is disposed an electrical heating element 5 of annular shape and comprising two spaced, superposed resistance wire coils. In place of the latter may be used an infra-red element. Disposed below the heating element 5 is a blower formed of a motor 6 mounted centrally in the hood and fan blades 8 mounted on the axle 7 of said motor. A closure grating 9 prevents access to the parts 4, 5 and 8. By means of a regulator 10, the flow of current and, therefore, the amount of ozone to be produced by the generator 4, may be set or determined as desired.

The ozone (O generated by the ozone generator is drawn downwardly by the blower or blades and fed through the grating 9 to a point of hair contact which is situated within the range of the open hood space. The oxygen passing from the ozone generator is deflected by the motor housing 6 towards the heating element and thereby is mixed with the air stream which enters through the louvers 11. Outside air enters through the louvers 11. The outside air drawn into the upper end of the hood through the openings 11 by means of the fan blades 8 passes over the lower side of the ozone generator 4 and is at that point mixed with the generated ozone and this mixture will thereafter pass over the heating wires 5 and be warmed. This operation definitely results from the showing of the apparatus in the figure of the drawing so that the air is mixed with the ozone and then heated. The drawing is believed to show that the ozone generated by the member 4 mixes with the air drawn in through the inlets 11 and this mixture being drawn downwardly by the fans 8 passes over the resistance elements 5 to be heated. Oxygen and warm air, well mixed, pass to the hair, said air being dry having been heated by the element 5. The ozone, which is indispensable for aiding the process of oxidation when bleaching, dyeing and undulating the hair, thus is generated within the hood and in vicinity of hair contact. Of importance is that the ozone generated is not contacted by nor mixed with steam, since thereby the favorable efiect would be impaired, as contact with wet elements lead to a spontaneous decomposition of the ozone.

While the invention has been described in detail with respect to a now preferred example and embodiment of the invention it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended, therefore, to cover all such changes and modifications in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A device for drying human head of hair comprising an upper hood portion and a lower hood portion, said portions being separated by a perforate partition, air inlet means in said upper hood portion and blower means mounted in said upper hood portion below said air inlet means for drawing air in through said air inlet means and for delivering air to said lower portion, heater means mounted in said upper hood portion, and ozone generating means mounted in said upper hood portion above and in close proximity to said heater means, whereby said air drawn into said upper hood portion is ozonized and heated prior to delivery to said lower hood portion.

2. A device for drying human head of hair comprising an upper hood portion and a lower hood portion, said portions being separated by a perforate partition, means for circulating air through said upper hood portion and from said upper hood portion to said lower hood portion, heater means mounted in said upper hood portion in the path of said circulating air, ozone generating means in said upper hood portion in the path of said circulating air above said heater means, whereby said air in said upper hood portion is ozonized and heated prior to delivery to said lower hood portion.
