No. 572,788 Claims priority, application Great Britain, Dec. 15, 1965, 53,168/65 3 Claims. (Cl. 34-97) ABSTRACT OF THE DISCLOSURE It is well known in various ways to blow washed hair dry by a hot stream of air. It is also known to obtain a coiffure by blowing. The known apparatuses have, however, in common that they are inconvenient, the inconveniences being burnt scalp, neck and ears.

The object of the present invention is to provide a hair drier by which it is possible in one operation to dry the hair and to provide it with a coitfure without the inconveniences mentioned above.

According to the invention a hair drier with a handle, in which is placed an electric resistance, is provided with a rotatable pointed rotor which is mounted and shaped in such a way that implements placed upon the rotor can be turned independent of the position of the hand, and is provided with openings for a cold stream of air, said openings being such that a mantle of cold air is formed around the implement, e.g., a curler, said stream of air being provided by a blower which advantageously may be connected to the handle by means of a flexible tube.

According to the invention the rotor may be shaped as a tubular projection which is shaped to support detachable curlers, e.g., of various forms, and which rotor is provided with openings for hot air. According to the invention the inside tubular curler may be provided with a metal body on the inside which body has a high heat conductivity and is provided with slits or other openings which are staggered relative to the openings in the outer part of the curler in such a way that the air is blown sideways under and into the hair wound on the curler. Thus the scalp, the neck and the ears are not burnt by a direct stream of hot air, but the person whose hair is being dried feels that the hair is being dried by cold or at least convenient air.

With the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

Other objects and advantages will become apparent from the following description taken in conjunction with the accompanying drawing in which:

FIG. 1 schematically illustrates a hair drier according to the invention seen from the side without detachable implements such as curlers, and with parts of the outer casing broken away,

FIG. 2 a section along the line IIII in FIG. 1,

FIG. 3 a section along the line IIIIII in FIG. 1,

FIG. 4 a detachable implement in the shape of a curler, depicted schematically with a special fabric,

ice

FIG. 5 said curler seen from the end, without the fabric,

FIG. 6 a cross section through said curler, and

FIG. 7 schematically illustrates the hair drier with a curler thereon wrapped with hair.

Referring to the drawings, and more particularly to FIGURE 1, it will be seen that the hair drier according to the invention comprises an electric heating resistance 11, placed in a hollow generally tubular plastic handle 12 within a glass tube 13. The one end of the handle 12 is connected to a blower hose not shown on the drawing, and the resistance 11 is connected to a not shown switch. The resistance may be placed in the tube 13 insulated with asbestos.

The glass tube 13 is surrounded with a plastic tube 14 so that an annular cooling channel 15 is formed between the two tubes which both are tapering in the same way as venturi tubes, the tube 14 being the longest and extending through a partition 16 into a tube 17 which is adapted to be received in an end 12' of the handle 12 and provided with openings or slots 18 through which the Warm air from the heated tube 13 and the channel 15 is conducted. The end 12' is rotatably mounted on the handle 12. The free end of the tube 17 may be more or less sharply pointed.

19 indicates the annular space between the tube 14 and the handle 12 through which space cold air from the blower is conducted to openings 20, FIG. 3, in the hollow rotatable part 12', surrounding the tube 17 in such a way that the cold air cools the scalp.

The blower is preferably placed outside the hair drier so that the weight to be handled is very light. Also the blower hose may be made of a light weight material.

The hair drier may be provided with detachable implements such as curlers or combs or other implements.

In FIGS. 4 to 6 a special curler is shown from the side in FIG. 4 where 40 indicates a tubular body of plastic material, into which is inserted a ring 42, and which is provided with a slit 44 and several slots 48, in the present embodiment four slots 48. The ring 42 supports an inner metal tube 46 which extends under the slots 48, and at the other end is supported in a manner not shown so that there is formed an annular space 52. The tube 46 is provided with openings 50, and as it appears from FIG. 6, there is provided two openings 50, staggered relatively to the slots 48. Air from the slots 18 will, when the curler is placed on the rotor 12, 17, pass through the openings 50 into the space 52 and from there out through the slots 48.

On the outside the body 40 is provided with strips of a fabric to which the hair can adhere such as a fabric having loops of nylon which loops are cut open.

The hair drier is operated in the following way:

An implement as the curler described above is placed on the tube 17 onto which it is held by friction. The part 12' is provided with a projection, not shown, corresponding to the slit 44, and the part 12' can be rotated by means of the thumb or another finger while the other fingers hold the handle, independent of the position of the hand. A tuft of wet hair can be wound on the curler, and the electrical current is connected now to the resistance 11 for some seconds. The moisture in the hair evaporates, after which the current is disconnected. The hair is rolled onto the curler to the scalp, and the curler is removed from the tube '17 and left in its place. Curler after curler is placed and heated in this way, the remaining moisture evaporating from the hair due to the heat remaining in the curlers. Finally, the curlers are removed, and the hair is curled and dry.

The warm air obtains quickly a rather high temperature, for example 200 C. in one second. The volume of cool air necessary for the cooling is sucked and blown through the cooling channel 15.

The openings, slots and channels in the apparatus for the cold air have the exact size which is necessary to provide the air mantle from the openings 20 around the hair which removes humidity and inconvenience from the heat.

What I claim is:

1. A hair drier having a handle in which is placed an electrical resistance, comprising a rotor which is mounted and placed in such a Way that implements placed upon the rotor can be turned independent of the position of the hand, said rotor or handle being provided with openings for a cold stream of air, said arrangement being such that a mantle of cold air is formed around the implement, e.g., a curler, said stream of air being provided from a blower which preferably is connected to the handle by means of a flexible tube.

2. A hair drier according to claim 1, in which the rotor is shaped to support detachable curlers .e.g. of various forms, said rotor having openings for warm air.

3. A hair drier according to claim 2, in which the inside tubular curler is shaped to have a metal body on the inside, said body having a high heat conductivity and being provided with slots or other openings staggered relatively to the openings in the outer part of the curler in such a way that the air is blown sideways under and into the hair wound on the curler.
