2 Claims.

The present invention relates to a hair drier construction, and it particularly relates to a hair drier construction for use in connection with hair waving operations.

In the usual hair drier constructions, hot air is blown onto or over the head or top of the head of the woman whose hair is being dressed or prepared, and the heat of the drier often causes substantial discomfort. Frequently, it becomes unbearable in summer weather or in semitropical climates.

It is among the objects of the present invention to provide a simple, improved, readily constructed hair drier arrangement which will enable greater comfort for the user of the hair drying device and at the same time will not detract or slow the drying operation.

Another object is to provide an improved hair drier construction which will enable ready drying of the hair with hot air, without undue or unnecessary discomfort to the user of the equipment.

Still further objects and advantages will appear from the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the zero objects, it has been found most suitable according to one embodiment of the present invention to provide a plurality of shells, an inner shell serving to circulate hot drying air over the head or hair, while the outer shell permits the flow of cooling air over the face and body of the user ofthe equipment so that discomfort is avoided.

In the preferred construction, the inner shell is fitted inside the outer shell and is insulated therefrom so that it is possible to force cooling air through the outer shell without it being heated from the inner shell, and at the open end of the shells means is provided to adust and regulate the flow of cooling air from the outer shell to the desired amount.

In one form of construction, separate fans or blowers are positioned at the base of the inner and outer shells to circulate the hot air in the inner shell and propel the cooling air in the outer shell, and these propellers or blowers may be driven from a single motor or from separate motors controlled individually or separately on the outside of the inverted shell structure.

It may also be desirable to provide auxiliary liners or smaller sleeves in the inner shell to assure better circulation of the air therewithin and to assure more effective heating thereof by the coil.

Referring to the drawing which shows one embodiment of the construction according to the present invention, but to which the present invention is by no means restricted, since many changes and variations may be made, all within the scope thereof.

Fig. 1 is a front elevational view of one form of hair drier construction according to the present invention;

Fig. 2 is a transverse sectional view upon an enlarged scale upon the line 2-2 of Fig, 1;

Fig. 3 is a transverse sectional view upon the line 3-3 of Fig. 2; and

Fig. 4 is a fragmentary transverse sectional view similar to the upper portion of Fig. 2 showing an alternative construction.

Referring to Figs. 1 to 3, the drier is provided with a stand A, an outer or cooler shell B, an inner or heater shell C, a. flow adjustment D and the motor E, with the hot air circulating means F and the cool air propeller means G. The motor E is controlled by the switch H.

As shown best in Figs. 2 and 3, the inner shell C is provided with a lining member Ill and an outer shell member II, which are separated by the insulating material H which may be of cork, if desired, and at the base of the shell is provided the heating coil l8 which is connected by the conduit It to the box I5 of the switch.

The screen It protects the coil l3 and, if desired, a perforated sheet metal or screen-like shield I! may be employed to aid in circulation of the hot air in the interior chamber l8 of the drier. For example, when the fan or propeller F is driven by its shaft ill from the motor E, it

will tend to blow the hot air as indicated by the arrows 20, toward'the mouth of the inner shell C, while other air will be drawn rearwardly through the passage on the outside of the sleeve IT as indicated by the arrows 2|.

The outer shell B is connected to the inner shell C by the U-shaped brackets 30 and also by the outer plate ring member 81, which is provided with a large number of openings 82 which may be closed by the rotatable ring member 33. This ring member 33 i controlled by the stud 36. which slides backwardlv and forwardly in the slot 38. By adjusting the position of the stud 35 and the slot 85, the amount of air flowing through the openings 32 as indicated by the arrows 8? in Fig. 2, may be adjusted.

It will be noted that the motor E, as shown in Fig. 2. is positioned on the back end of the inner shell C and that the propeller G is so arranged as to draw in cooling air through the openings 40, as indicated by the arrows 4i and then force it through the space 42, as indicated by the arrows 43, to the openings 32. The electrical connections from the switch box H extend as indicated at 50, through the ball joint 5| into the stand member 52. The ball member 5| is attached by the bracket 53 to the rear face of the shell B. The switch member 54 which projects through the shell B enables switching on and ofi of the current to the coil l3 and the motor E.

In operation, the head or hair of the person using the equipment is inserted in the inner shell C, where the hot air is circulated by the fan or propeller F to dry the hair. At the same time, by moving the stud or handle member 34 in the slot 35, the amount of air flowing out through the openings 32 over the face and body of the user may be regulated.

If desired, the inner structure 16 and l I may be eliminated, or the screen sleeve I! may be replaced by perforated sleeve or by a solid sheet metal sleeve.

In the construction of Fig. 4, correspondingly functioning parts being indicated by the same numerals primed as in Figs. 1 to 3, two motors are provided, namely, a motor 60 for driving the propeller F, and a motor SI for driving the propeller G. The switch 62 controls the motor 60, while the switch 83 controls the motor 6|, so that it is possible to switch on and of! the cooling air motor 6| when desired.

If desired, it would also be possible to utilize an electric cooling device inside the back of the outer shell B, or outside of said shell, through which the air would have to pass before entering the openings 40.

It is thus apparent that the present applicant has provided a simple, inexpensive, effective drier which will eliminate most of the discomfort associated with present-day driers, and.which will assure supplying an adjustable amount of cooling air to a. person undergoing treatment.

It will be understood that many changes could be made in the particular features of hair drier as shown, and many apparently widely difierent embodiments of this invention could be made without departing from the scope thereof. It is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.

What is claimed is:

1. A hair drier comprising an imperforate inner heater shell having an electric heater therein, a

larger outer shell defining a cooling space about said inner shell, means near the rims of the re spective shells maintaining them in assembled coaxial relation, a perforated annulus interposed between the rims of the shells, an electric fan in the space between the two shells, said fan being arranged to blow outwardly toward and through the annulus, the base of said outer shell being perforated for drawing of air into said cooling space.

2. The hair drier as defined in claim 1 in which the annulus has an associated perforated ring member rotarily adjustable to determine the size of air passages through the cooling space.
