Definitions
- the present disclosure relates generally to hair dryers and specifically to a hair dryer with non-parallel air flow and a hair dryer with multiples modes of operation including a mode with non-parallel air flow.
- Conventional hair dryers discharge air from the end of a barrel in only one direction. Air is discharged from a relatively small surface area, which limits the amount of hair that may be dried at a particular moment in time slowing down the hair drying process.
- conventional hair dryers discharge air at relatively high speeds and temperatures.
- the relatively high speeds cause the hair to move away from the air in various directions even when held in place with the brush. This causes the hair to become frizzy and tangled.
- the relatively high temperatures may be uncomfortable for the user and may be unhealthy to the hair and the scalp.
- hair may be held in place against the high speed hot air by pushing the hair against the scalp with the end of the barrel of the hair dryer. This, however, focuses additional heat on the hair and the scalp which may be uncomfortable for the user and may be unhealthy to the hair and the scalp.
- the present disclosure describes a hair dryer that may operate in a single mode or multiple modes.
- the hair dryer may operate in a through mode that allows for hair to pass through a gap to which warm air is directed from multiple directions. This mode of operation may dry the hair faster and may result in less tangles. The through mode of operation may also allow for heat to be less focused on the scalp, which may be more comfortable and perhaps healthier for the user's hair and scalp.
- the hair dryer described in the present disclosure may also include a panel mode in which the hair dryer discharges air from a panel-like surface area.
- the panel-like surface area is significantly larger than the surface area of a barrel of a conventional hair dryer. This may allow for relatively faster drying and may help smooth the cuticle of the hair providing a smooth look and added shine to the hair. It may also allow for preserving natural curl patterns of the hair.
- the hair dryer described in the present disclosure may provide the above-described modes of operation in addition to a mode of operation that resembles conventional hair dryers. This makes for a versatile device that offers different modes of operation without the need to acquire or replace attachments such as diffusers or concentrators.
- the hair dryer described in the present disclosure may allow for hair drying with only one tool and potentially one hand.

Abstract
A hair dryer includes a body having a handle portion, a middle portion operatively connected to the handle portion and at least one air duct portion extending away from the middle portion in a direction non-parallel to the handle portion and having walls with apertures. The hair dryer also includes a blower mounted within the body to generate an air flow through the at least one air duct portion to discharge through the apertures on the walls of the at least one air duct portion in a direction non-parallel to a central axis of the at least one air duct portion.
Description
- The present disclosure relates generally to hair dryers and specifically to a hair dryer with non-parallel air flow and a hair dryer with multiples modes of operation including a mode with non-parallel air flow.
- Conventionally, users or consumers use the combination of a brush and a hair dryer to dry, straighten and smooth their hair. The user pulls the hair tight and keeps tension on the hair with the brush. The user then applies warm air directionally onto the tensioned hair with the hair dryer. This process requires two tools (i.e., the brush and the hair dryer) and two hands.
- Conventional hair dryers discharge air from the end of a barrel in only one direction. Air is discharged from a relatively small surface area, which limits the amount of hair that may be dried at a particular moment in time slowing down the hair drying process.
- To make up for the relatively small surface area and speed up the hair drying process, conventional hair dryers discharge air at relatively high speeds and temperatures. The relatively high speeds cause the hair to move away from the air in various directions even when held in place with the brush. This causes the hair to become frizzy and tangled. The relatively high temperatures may be uncomfortable for the user and may be unhealthy to the hair and the scalp. In some cases hair may be held in place against the high speed hot air by pushing the hair against the scalp with the end of the barrel of the hair dryer. This, however, focuses additional heat on the hair and the scalp which may be uncomfortable for the user and may be unhealthy to the hair and the scalp.
- Accessories that attach to the hair dryer such as diffusers and concentrators have been devised to address some of these problems. These devices, however, may not completely address the above-described issues and, moreover, attaching these accessories to the hair dryer or brush adds complexity and time to the hair drying process.
- The present disclosure describes a hair dryer that may operate in a single mode or multiple modes.
- The hair dryer may operate in a through mode that allows for hair to pass through a gap to which warm air is directed from multiple directions. This mode of operation may dry the hair faster and may result in less tangles. The through mode of operation may also allow for heat to be less focused on the scalp, which may be more comfortable and perhaps healthier for the user's hair and scalp.
- The hair dryer described in the present disclosure may also include a panel mode in which the hair dryer discharges air from a panel-like surface area. The panel-like surface area is significantly larger than the surface area of a barrel of a conventional hair dryer. This may allow for relatively faster drying and may help smooth the cuticle of the hair providing a smooth look and added shine to the hair. It may also allow for preserving natural curl patterns of the hair.
- The hair dryer described in the present disclosure may provide the above-described modes of operation in addition to a mode of operation that resembles conventional hair dryers. This makes for a versatile device that offers different modes of operation without the need to acquire or replace attachments such as diffusers or concentrators. The hair dryer described in the present disclosure may allow for hair drying with only one tool and potentially one hand.
- The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate various example systems, methods, and so on, that illustrate various example embodiments of aspects of the invention. It will be appreciated that the illustrated element boundaries (e.g., boxes, groups of boxes, or other shapes) in the figures represent one example of the boundaries. One of ordinary skill in the art will appreciate that one element may be designed as multiple elements or that multiple elements may be designed as one element. An element shown as an internal component of another element may be implemented as an external component and vice versa. Furthermore, elements may not be drawn to scale.

FIGS. 1A-2C illustrate various views of anexemplary hair dryer 10. The hair dryer includes ahandle portion 20,air duct portions middle portion 40 disposed between thehandle portion 20 and theair duct portions hair dryer 10 also includesnozzles air duct portions air duct portions apertures 34, examples of which areapertures walls - The
hair dryer 10 also includes aswitch 50,apertures 60 and a blower (not shown). The blower may include a motor, a fan, a turbine, etc. and is mounted within the body of thehair dryer 10. The blower is operatively connected to theswitch 50 such that operation of theswitch 50 causes the blower to operate. Operation of the blower generates a forced flow of air that enters through theapertures 60, flows through at least a portion of theair duct portions apertures 34 depending on the set mode of operation as described below. - In the illustrated embodiment, the
hair dryer 10 includes apower cable 70 to transfer power from, for example, a power outlet to thedryer 10. In other embodiments (not shown), thedryer 10 receives power from sources other than a power cable connected to a power outlet such as, for example, a battery disposed within or outside thehair dryer 10. - Modes of Operation
- The
hair dryer 10 may operate in at least three different hair drying modes: a) a traditional mode, b) a through mode, and c) a panel mode, each of which is discussed in detail below. Thehair dryer 10 may operate in only one or only two of the traditional mode, the through mode or the panel mode by themselves or in combination with other modes not disclosed herein. -
FIG. 3A illustrates operation of thehair dryer 10 in traditional mode. In the traditional mode the forced air flow F generated by the blower discharges through thenozzles air duct portions - As its name suggests, the traditional mode provides hair drying similar to that of conventional hair dryers. The
hair dryer 10, however, includes theair duct portions air duct portions -
FIG. 3B and 3C illustrate operation of thehair dryer 10 in through mode and panel mode, respectively. In these two modes, the forced air flow F generated by the blower does not discharge through the nozzles 32. Instead, in through mode and panel mode the forced air flow F generated by the blower discharges through theapertures 34 on the walls 36 of the air duct portions 30. The force air flow discharges in a direction non-parallel to the central axes La and Lb of theair duct portions - In particular,
FIG. 3B illustrates operation of thehair dryer 10 in through mode. In through mode theair duct portions air duct portions apertures 34 on the walls 36 into the gap G in a direction non-parallel to the central axes La and Lb. The force air flow F discharges through theapertures 34 a of the firstair duct portion 30 a towards the secondair duct portion 30 b. Similarly, the force air flow F discharges through theapertures 34 b of the secondair duct portion 30 b towards the firstair duct portion 30 a. - Through mode operation, as illustrated in
FIG. 3B , allows hair to slide through the gap G between the separatedair duct portions air duct portions - In one embodiment, the gap G is variable. The gap G may be controlled by a button or switch such that the user may widen or close the gap G. In one embodiment, the gap G is be controlled for the walls 36 of the air duct portions 32 to become very close together or touch with the hair in the gap G to effectively clamp onto the hair.
-
FIG. 3C illustrates operation of thehair dryer 10 in panel mode. In panel mode theair duct portions apertures 34 on the walls 36 in a direction non-parallel to the central axes La and Lb. The force air flow F discharges through theapertures 34 a of the firstair duct portion 30 a in a direction not towards the secondair duct portion 30 b. Similarly, the force air flow F discharges through theapertures 34 b of the secondair duct portion 30 b in a direction not towards the firstair duct portion 30 a. - In one embodiment, the force air flow F discharges through the
apertures 34 b of the secondair duct portion 30 b in generally the same direction that the force air flow F discharges through theapertures 34 a of the firstair duct portion 30 a. In one embodiment, the force air flow F discharges through theapertures air duct portions handle portion 20. In other embodiments, the force air flow F discharges through theapertures air duct portions - In one embodiment, the force air flow F discharges through the
apertures air duct portions apertures 34 a of theair duct portion 30 a converge with the air flowing from theapertures 34 b of theair duct portion 30 b. In one embodiment, the force air flow F discharges through theapertures air duct portions apertures 34 a of theair duct portion 30 a does not converge with the air flowing from theapertures 34 b of theair duct portion 30 b. - Panel mode operation provides a much larger surface area from which air flows to the hair as compared to conventional hair dryers. Thus panel mode may potentially help dry hair faster and may allow for effective hair drying using lower speeds and temperatures than conventional hair dryers. Panel mode operation may also allow for effective hair drying while preserving natural curl patterns. For example, natural curl may be preserved or enhanced if air flow in panel mode is such that the hair is allowed to lay onto the walls 36 and be dried in a coiled curled state.
- In one embodiment (not shown), the
air duct portions apertures 34 on the walls 36 in a direction non-parallel to the central axes La and Lb, but in the opposite direction as that shown inFIG. 3C . In this embodiment, force air flow F may flow essentially upwards. In this embodiment, natural curl, for example, may be preserved or enhanced if the hair is allowed to lay onto the walls 36 and be dried in a coiled curled state. -
FIGS. 1A-1E illustrate additional views of thehair dryer 10 potentially in through mode.FIGS. 2A-2C illustrate additional views of thehair dryer 10 potentially in panel mode. - In the illustrated embodiment (see for example
FIGS. 1A and 2A ), thehair dryer 10 includes adial 80 disposed on themiddle portion 40. Thedial 80 may be operatively connected to theair duct portions dial 80 to cause thefirst duct portion 30 a and thesecond duct portion 30 b to rotate in opposite directions. By operation of thedial 80 the user may rotate theair duct portions middle portion 40 from the position corresponding to the through mode of operation (FIG. 1A ) to the position corresponding to the panel mode of operation (FIG. 2A ) as described above. Similarly, by operation of thedial 80 the user may rotate theair duct portions FIG. 2A ) to the position corresponding to the through mode operation (FIG. 1A ). - As may be seen from
FIGS. 1B and 1C , in through mode theair duct portions dial 80 the user dials theair duct portions - As may be seen from
FIGS. 2B and 2C , in panel mode theair duct portions dial 80 the user dials theair duct portions - In other embodiments, the
air duct portions - The
hair dryer 10 includes an air directing mechanism (not shown) that directs the air flow from the blower through the nozzles 32 in traditional mode and from the blower through theapertures 34 in through mode and panel mode. This air directing mechanism may also block air flow to theapertures 34 in the traditional mode and may block air flow to the nozzles 32 in through mode and panel mode. - In one embodiment, the air directing mechanism includes a set of flaps (not shown) that blocks or allows air flow to the nozzles 32 or the
apertures 34 depending on the set operational mode. In one embodiment, flaps close off the nozzles 32 in through mode and panel mode to direct air from the blower through theapertures 34. In this embodiment, when the flaps are opened air flows from the blower through the nozzles 32. Thus, in this embodiment, both the nozzles 32 and theapertures 34 are open in traditional mode, but the air flows naturally from the blower through the nozzles 32. - In the illustrated embodiment, the
hair dryer 10 includes aswitch 90 that operates the flaps and thus, at least in part, controls the mode of operation together with thedial 80 as described above. Operation of theswitch 90 transitions the hair dryer from traditional mode to through mode, from through mode to traditional mode, from traditional mode to panel mode or from panel mode to traditional mode. In another embodiment, transition of operation from a first mode to another mode of operation is controlled by means other than thedial 80 and/or theswitch 90. - While example devices, methods, and so on, have been illustrated by describing examples, and while the examples have been described in considerable detail, it is not the intention to restrict or in any way limit the scope of the appended claims to such detail. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the devices, methods, and so on, described herein. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention is not limited to the specific details, and illustrative examples shown or described. Thus, this application is intended to embrace alterations, modifications, and variations that fall within the scope of the appended claims. Furthermore, the preceding description is not meant to limit the scope of the invention. Rather, the scope of the invention is to be determined by the appended claims and their equivalents.
- To the extent that the term “includes” or “including” is employed in the detailed description or the claims, it is intended to be inclusive in a manner similar to the term “comprising” as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term “or” is employed in the detailed description or claims (e.g., A or B) it is intended to mean “A or B or both”. When the applicants intend to indicate “only A or B but not both” then the term “only A or B but not both” will be employed. Thus, use of the term “or” herein is the inclusive, and not the exclusive use. See, Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995).
