17 Claims. 1

This invention relates to a new and improved hair drier for use in beauty parlors.

Beauty parlor operators have long' recognized the need for a hair drier so designed that the customer may relax and rest, or sleep, while her hair is'being dried. They have also recognized that the driers now available commercially are objectionable from the standpoint that the hot air flowing over the face for the half hour to an hour that it takes for the hair to dry dries out the skin to a very noticeable extent which is distinctly annoying to many customers, and eliminates any likelihood of their resting comfortably during such an ordeal. It is, therefore, the principal object of my invention to provide a hair drier so designed and constructed as to avoid the objections mentioned, the drier being formed as an integral part of a unit with a comfortable chair, to induce relaxation, and being, furthermore, provided with its cool air inlet so located that there will always be a soothing flow of cool air over the customers face, for the double purpose of offsetting the heating effect of the drier and preventing flow of hot air over the face, any hot air leaking from the drier being entrained with the incoming cool air, so that it cannot give the undesirable drying action on the skin, and the overall efilciency of the unit as a drier is improved by reason of the reduction in the loss of air heated.

A salient feature of the hair drier of my invention is the fact that the heat source and blower fan are below and behind the head during the drying operation, so that the hair tends to project toward the heat source and can, therefore, be dried more efllciently, and the heat tending to rise naturally reaches all portions of the scalp to be dried without requiring nearly as energetic blowing action.

Another object of the invention consists in the provision in the drier housing of a cool air inlet passage and a hot air recirculation passage in parallel relation, extending lengthwise of the housing from a point above the head opening to a point below the fan and heating element, where the cool air passage discharge into the housing and the hot air recirculation lpassage also discharges a certain amount of hot air to be entrained with the cool air, a regulatable outlet being provided at the same point to permit escape of avariable amount of the moisture laden hot air, equivalent approximately to the amount of cool air taken in.

Still another object consists in the provision of an improved combined fan and heating means,

which permits locating the fan in closer proximity to the hair to be dried without danger of scorching orburning with radiant heat, whereby greatly to improve the drying efficiency, the heating elements being provided directly in or on the fan, preferably between the blades thereof, so that any strands of hair that might protrude through the protecting screen, disposed in the housing below the head opening, cannot come in contact with the heating elements and the radiant heat is distributed to a comfortabledegree to-ali parts of the scalp.

The invention is illustrated in the accompanying drawing, in which Figs. 1 and 2 are, respectively, a side view and top view of a hair drier unit made in accordance with my invention;

Fig. 3 is a front view of the drier housing and neck supporting cushion, showing the head opening between the neck cushion and the flexible sealing strip that fits over the forehead, this view being taken on the line 33 of Fig. 4;

Fig. 4 is a vertical-section through the drier end of the unit, taken onthe line 4--4 of Fig. 2, but on a larger scale, and

Fig. 5 is a face view of the fan showing the heating coils in the openings between the blades thereof.

The same reference numerals are applied to corresponding parts throughout the views.

Referring to the drawing, the reference numeral I0 designates a generally U-shaped frame that is preferably, though not necessarily, of tubular metallic construction, there being a U- shaped base portion l I and generally rectangularshaped end portions I2 which provide arm rests for the chair l3. The latter is of heavily upholstered construction and has a semi-reclining back I and is suitably attached, as at [5. to the base portion of the frame l0. A number of seat cushions ii are provided on the chair, in order that the operator may quickly adjust the chair to people of different height. Two cushions will ordinarily'sufiice, but, as indicated in dotted lines, a third cushion may be provided if desired and thus accommodate children as well as adults, The foot stool ll, upholstered to match the upholstery of the chair i3, is also preferably, though not necessarily, supported on the base portion of the frame i0, that the operator can, if he so desires, move the entire ensemble as a unit, by grasping the rear upwardly projecting handle extensions [8 and pulling or pushing the unit from one place to another. The unit will not weigh so much as to make such sliding movement of the unit from one spot to another in a beauty parlor at all diflicult. When the proper number of seat cushions l5 have been placed in the chair, the customer seated in the chair can rest the back of her neck on the cushion I9, that is mounted on a support 20 on top of the chair back l4. This cushion fits snugly in a cut-away front portion 2| in the lower wall of the head opening 22 provided in the upper end of the drier housing 23. The housing 23 is supported on the frame [I] between the handle portions l8 and extends from a point near the base upwardly and is curved forwardly at its upper end where the head opening 22 and the cushion |9 are provided.

The housing 23 is shown in section in Fig. 4 and has three

curved walls

24, 25, and 26 forming the back thereof to define a cool air inlet passage 21 and a hot air recirculation passage 28 extending lengthwise of the housing parallel to one another. An inner front wall 26a is provided in spaced relation to the outer front wall of the housing 23, to provide a secondary hot air recirculation passage 28a in the front portion of the housing leading from the lower front portion of the drying chamber D and communicating with the lower portion of the fan chamber F. A separate front top housing section 29 is hinged on the top wall of the housing 23, as at 30, transversely of the upper end of the housing, to provide a larger head opening, so that the occupant of the chair can place her head over the cushion l9 and have her hair, indicated at 3|, arranged by the operator inside the drying chamber D for quickest drying, as, for example, when the hair is to be partially dried preparatory to permanent waving. The operator, in other words, can reach past the persons head into the drying chamber D so long as the hinged section 29 is swung back out of the way, as indicated in dotted lines in Fig. 1. The parting line between the upper end portion of the housing and the section 29 is indicated at 32 in Fig. 4. The hinged section 29 has three walls, 34, 35, and 36, which register with the ends of the

walls

24, 25, and 26, respectively, when the hinged section is in closed operative position, whereby to define

extensions

31 and 38 of the cool air inlet passage 21 and hot air recirculation passage 28, respectively. The walls 34 and 35 extend forwardly beyond the end of the wall 36 and are curved downwardly, as indicated at 39, for three reasons: First, to restrict the head opening 20 so that the end portion 40 of the wall 35 will lie in a predetermined spaced relationship t0 the forehead of the chair occupant and accordingly reduce the size of the forehead and temple engaging seal means (4|) necessary; secondly, to provide a support for the flexible seal strip 4| on the end portion 40 of the wall 35, the strip being fastened by screws or rivets, as indicated at 42, and extending radially inwardly with respect to the head opening 22 for sealing engagement over the forehead and temples of the chair occupant, as indicated in Fig. 4; and, thirdly, to provide the cool air inlet opening 43 in sufficiently close proximity to the sealing strip 4| and the face of the chair occupant to afford the desired cooling effect in the operation of the drier and, at the same time, insure entrainment with the ingoing cool air of any hot air that may leak out around the head of the chair occupant, and in that way avoid one of the most serious objections common to earlier driers. It is important to note that although the face is cooled, there is no opportunity for cool air to reach the moist scalp and chill the head and also interfere with the eflicient drying of the hair. The cool air taken in does not even lower the temperature of the warm air directed against the scalp, because the cool air inlet passage 31 is above and on the outer side of the hot air recirculation passage 38, The strip 4|, as indicated in Fig. 3, extends in a semi-circle around the upper portion of the head opening 22, and the cushion l9 extends in an are around the lower portion of the head opening and has its ends in spaced relation to the ends of the sealing strip 4|, as indicated at 44, so as to afford clearance for the ears and the pin curls that are usually formed adjacent the ears, the head being inserted in the drier far enough to dry these pin curls. If desired, towels, wads, or shields may be placed under the neck and up in front of the ears to help to seal the drier against loss of hot air during the operation of the drier. The strip 4| may be of rubber, or rubberized cloth, or other flexible and preferably resilient material. The cushion l9 may be of ponge rubber, or any other yieldable and preferably resilient material, and when made of sponge rubber is slotted lengthwise, as indicated at 45 in Fig. 4, to receive the support 20. The cushion can be compressed endwise as well as sidewise to the extent required to effectively seal the opening 2| so that there will be no leakage of hot air at this point. If desired, the cushion [9 may be made adjustable with respect to the support 20, or the support may be vertically adjustable with respect to the back of the chair, whereby to adjust the cushion l9 vertically in the head opening 22 as may be required to adapt the device to different sizes of heads and accordingly get the desired sealing action with the flexible seal strip 4| under all conditions.

The screen indicated at 41 extends substantially the full width of the inside of the drying chamber D, substantially horizontally, slightly below the head opening 22, so as to support any longer strands of hair that might otherwise come in contact with the fan 48. The latter is driven by an electric motor 49. the speed of operation of which may be controlled by a rheostat 50, or by any multiple speed switch means, to vary the air flow as desired, although, of course, a. single speed switch may be employed. The location of the screen 41 below and behind the head with the fan discharging warm air upwardly therethrough is found to give much more efficient drying action without requiring nearly as energetic blowing action, because, for one thing, the hair projects more or less toward the screen thus aifording a better opportunity for the warm air to reach the scalp, and the heat tends to rise naturally to all portions of the scalp to be dried so that a gentle blower action is sufficient and less heat is required. The motor 49 is supported on a bracket 5| inside an elongated tubular housing 52 that is of streamlined cross-section, as indicated in Fig. 4, with the small end of the section toward the fan 48 and the large end remote therefrom, whereby to reduce the resistance to air flow past the housing to a minimum. The housing 52 is suitably supported at opposite ends on the side walls of the housing 2|, and louvers 53 are provided in the opposite side walls of the housing communicating with the ends of the motor housing 52, so as to allow air circulation through the housing past the motor 49 to reduce likelihood of it overheating in the operation of the drier. The armature shaft 54 of the motor carries the fan 48 and, in accordance with the present invention, a hub Ill is provided onthe fan 48 made of electrical insulating material, whereby to insulate from one another two metal bands 56 that are connected with the opposite ends of an electrical heating coil 51; the various intermediate portions of which are preferably supported in the op nings 58 in the disk 9 between the blades 60 of the fan. Brushes 6| have leads extending therefrom to the. rheostat 62, whereby to provide for control of the heating effect. The rheostats 50 and 62 are provided on a control panel 63 that is preferably mounted on one of the arm rests l2 of the chair, so that the operator, or the chair occupant, can readily make adjustments both as to speed of operation of the fan and as to the heat delivered, and accordingly suit the comfort of the particular individual or the needs of the particular situation.

The fact that the heating coil, or coils, are not stationary but turn with the fan is of advantage for several reasons, one being that it eliminates any danger of any strands of hair that may protrude through the screen "coming into contact with the heating coils and being scorched or burned. This construction avoids discomfort to the chair occupant by reason of radiant heat from the heating elements, the radiant heat in this device being uniformly distributed to all parts of the scalp and accordingly giving greater comfort and increased efiiciency in the drying of the hair. It also makes for a reduction in the resistance to air flow through the housing and reduces the likelihood of lint and dust accumulating on the heating coils and thus further obstructing the air passages and increasing resistance to air flow, and it permits placing the heating means and fan much closer to the screen 41 and accordingly much closer to the hair to be dried, for most efficient drying action, without involving any danger of scorching or burning the hair. While I have shown only two rings 56 in connection with a single heating coil, it will, of course, be understood that a multiplicity of such rings may be provided for a number of coils, and the heat may then be controlled by connecting as many coils with the current source as may be desired, each opening 58 in the disk 59 having two, three, or even more heating elements therein.

Indicated at 10 are earphones, which are mounted in the opposite side walls of the housing 23, at points where these phones will be in sufficiently close proximity to the ears of the chair occupant to enable her to listen to radio programs or phonographic recordings. In Fig. 2 a small radio receiving set is indicated at H, having the usual dials I2 and 13 for station selection and volume control, the set being suitably secured to the arm rest l2, where it is in convenient reach of the chair occupant and operator. In some beauty parlors where a number of hair driers of the present type are installed, a combination radio and phonograph may be provided, and

phonograph records may be played and the earphones I0 connected with the radio set and each chair may be equipped with a switch to permit the occupant to l'sten either to the phonograph recordings or tun in outside broadcasts with the set 1| alternately. If soothing music is played on the phonograph, it naturally tends to aid relaxation and rest, and each chair occupant can choose the phonograph recordings or outside broadcasts, or neither, as she prefers.

In operation, the cool air is drawn in through the opening 43 that extends in an are over the forehead and around the temples of the chair occupant, and this cool air is conducted through passages 31 and 21 and enters the lower portion of the fan .chamber F at 84 and flows upwardly past the fan, where it is heated as it is discharged through the screen 41 against the hair of the chair occupant. Most of the moisture laden hot air is exhausted from the upper end of the drying chamber D through the 1 hot

air recirculation passages

38 and 28, and is conducted downwardly tothe point 64 of admission of the cool air, where there is one opening 65 communicating with the inside of the housing 23 and another opening 68 communicating with the outside of said housing. A certain amount of moisture laden hot air is exhausted from the lower front corner of the drying chamber D and conducted through the passage 28a to the lower portion of the fan chem.-

- ber F oppositethe point 64, where the cool air enters, so that this hot air will be entrained with thecool air as it flows upwardly toward the fan 48. A slide 61 adjustable by the operator by means of the thumb-piece 68 in the guides 69- provided on the back of the housing regulates the discharge of moisture laden hot air through the opening 66, and in that way there is a balance set up between the amount of cool air taken in and the amount of moisture laden hot air allowed to be exhausted, some of the moisture laden hot air being entrained in the opening 65'with the incoming cool air so as to more or less temper the incoming cool air prior to its reaching the, heating coil, or coils, 51, and accordingly increase the operating efilciency of the ,drier. In this connection, it should also be noted that the cool air inlet passage 21 extends the full length of the hot air recirculation passage 28 and there is accordingly a good opportunity for heat transfer through the intervening wall 25, so that the incoming cool air is subjected to an appreciable heating action even before it enters the lower portion of the housing 23.
