The present invention relates to an apparatus for drying hair, and in particular, a hair dryer with a light source.
Drying the hair of a person or an animal, in particular a large animal, in a dimly lit area poses a variety of difficulties, including over-drying or under-drying of the hair. Light bulbs and other external illumination methods are frequently inadequate for proper work area visualization for a variety of reasons, including the light being cumbersome or insufficient to adequately light the hair being dried. Professionals or others drying hair may also use brushes or other tools to add body or curls to the hair as it is drying. When the work area and the hair being dried are insufficiently illuminated, inefficiencies in drying exist because the condition of the hair cannot be readily ascertained.
In one embodiment, the invention provides a hair dryer including a housing having a nozzle portion terminating at a drying end. The housing defines a cavity. The hair dryer further includes a one light source coupled to the housing and positioned to direct light towards a work area proximate the drying end.
In another embodiment, the hair dryer includes a housing having a nozzle portion having a first end and a drying end. The housing defines a cavity and includes an aperture formed in the housing proximate the first end of the nozzle portion. The hair dryer further includes a holder and a light source supported by the holder and received by the aperture. The light source is positioned to direct light towards a work area adjacent to the drying end of the nozzle portion.
In another embodiment, the hair dryer includes a housing having a main portion and a nozzle portion terminating at a drying end. The housing defines a cavity and having apertures formed therein. The hair dryer includes a holder coupled to the housing and light sources supported by the holder and positioned substantially around a circumference of the nozzle portion. Each light source directs light through one of the plurality of apertures in the housing towards a work area adjacent to the drying end.
Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
The hair dryer 10 includes a hollow, elongated housing 14 having a forward housing 18 and a rear housing 22 and defining an inner cavity 26. The forward housing 18 includes a drying end 30. The housing 14 substantially houses and surrounds various dryer components, substantially located in the inner cavity 26, including, but not limited to, a heating element 34, a fan 38, a motor 42, a light source holder 46, light sources 50, and a shroud portion 54. The forward housing 18 and the rear housing 22 are coupled by a fastening mechanism 58 (
In operation, air flow is created by the fan 38 and the air flows through the heating element 34 toward the drying end 30 of the housing 14. Air exits the hair dryer 10 at the drying end 30 where the air acts upon the hair in a work area 62 adjacent the drying end 30. Light emitted from the light sources 50 is independent and separate of the air flow. Additionally, the light sources may be operated independently of the fan 38.
The hair dryer 10 includes the cavity 26 defined by both the forward housing 18 and the rear housing 22. The rear housing 22 includes an exhaust panel 66 configured to allow exhaust to exit the dryer 10. The forward housing 18 includes a nozzle 70. The nozzle 70 has a first end 29 and a drying end 30 (
Referring to
The shroud portion 54 is positioned in the cavity 26 rearward of the holder 46. The shroud portion 54 is configured to support the holder 46 and prevent interference of air flow within the cavity 26 by the presence of the light sources 50 and holder 46. More specifically, the shroud portion 54 provides a mounting area for the light source 50 and provides a shielding function for minimal disruption to the air flow of the dryer 10. The shroud portion 54 maintains an effective air flow pattern throughout the dryer 10 even with the light source 50, such that the air flow is not interrupted, swirling, or otherwise inconsistent to result in hot spots on the heating element 34, which may lead to premature failure of the heating element 34.
As illustrated in
In operation, the light sources 50 are retained by the holder 46 and placed in the recess apertures 90 to provide lighting in the work area 62. The holder 46 is supported within the cavity 26 by a shroud portion 54. The shroud portion 54 supports the holder 46 by coupling the holder 46 to the forward housing 18.
The hair dryer 10 further includes a light switch 118 (
In the illustrated embodiment, the light sources 50 are light-emitting diodes (LEDs) that emit white light, although any number of light colors may be used. The LEDs also allow for cool running temperatures of the light sources 50 and operate on low amounts of power. In the illustrated embodiment, the light sources 50 are arranged in a circular arrangement substantially surrounding the periphery of the nozzle 70. In a further embodiment, the recess apertures 90 may be in a linear or a non-linear arrangement, wherein one aperture may be in a more forward position than an adjacent aperture. The apertures may also be at various angles within the recess so that the light sources are directed at various angles to illuminate the work area adjacent the drying end. In a further embodiment, other light sources may be used, such as fiber optics, light bulbs, light tubes, or the like.
Placement of the light sources on the periphery of the housing prevents interference with other hair dryer attachments, such as a diffuser and the like. The light sources are also placed on the periphery of the nozzle of the hair dryer to avoid interference with the fan, motor and the heating element. Additionally, placement of the light sources rearward of the heating element aids in keeping the light sources cool.
Other embodiments of the present invention may utilize combinations of the above embodiments. The embodiments described above and illustrated in the figures are presented by way of example only and are not intended as a limitation upon the concepts and principles of the present invention. As such, it will be appreciated by one having ordinary skill in the art that various changes in the elements and their configuration and arrangement are possible without departing from the spirit and scope of the present invention as set forth in the appended claims.
