TECHNICAL FIELD

The present invention relates to hair dryers, specifically a modular hair dryer.

INDUSTRIAL APPLICABILITY

The present invention will be applicable in a variety of ways to a variety of industries. The invention may be used to dry hair, wherein the invention would be used domestically and commercially by hairstylists. DESCRIPTION OF THE RELATED ART

A hair dryer or a blow dryer is an electromechanical device designed to blow cool or hot air over wet or damp hair, in order to accelerate the evaporation of water particles and dry the hair. Hair dryers allow to better control the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds inside each strand. These hydrogen bonds are very powerful (allowing for stronger hair shaping than even the sulfur bonds formed by permanent waving products), but are temporary and extremely vulnerable to humidity. They disappear with a single washing of the hair. Hairstyles using hair dryers usually have volume and discipline, which can be further improved by the use of styling products and hairbrushes during drying to add tension, hold and lift. Hair dryers are used both in the beauty salon by professional stylists, and in the average household by consumers.

Most models use coils of wire that have a high electric resistivity and heat rapidly with an electric current. A fan usually blows ambient air past the hot coils resulting in heated air effective for drying. The heating element in most hairdryers is a bare, coiled nichrome wire that is wrapped around insulating mica heating boards. Nichrome wire is used in heating elements, because of two important properties: it is a poor conductor of electricity and it does not oxidize when heated.

Hair dryers are available with different attachments, such as diffusers, airflow concentrators, and comb nozzle attachments. A diffuser is an attachment that is used on hair that is fine, colored, permed or naturally curly. It works by diffusing the heat so that the hair dries more slowly at a cooler temperature. This makes it so that the hair is less likely to frizz and it gives the hair more volume. An airflow concentrator does the exact opposite of a diffuser. It makes the end of the hair dryer more narrow and thus helps to concentrate the heat into one spot in order to make it dry rapidly. The comb nozzle attachment is the same as the airflow concentrator, but it ends with comb-like teeth so that the user can dry the hair using just the dryer without a brush or comb.

Some improvements have been made in the field. Examples of references related to the present invention are described below in their own words, and the supporting teachings of each reference are incorporated by reference herein:

U.S. Patent No.: 7,926,198, issued to Merritt, discloses a handheld dryer having low power consumption is provided. A fan operates to cause air to be drawn into the housing of the dryer, creating an airstream of substantial velocity that is forced through a heater assembly. The heater assembly includes two Peltier thermoelectric modules in thermal communication with a plurality of heat sinks. The airstream generated by the fan passes through the heat sinks to remove the heat therefrom, and is, in turn, heated. The passage of the airstream through the dryer housing results in each thermoelectric module operating at essentially a zero temperature differential between its hot and cold face. Resultantly, hot air is discharged from the handheld dryer, which can be used to dry hair or other objects. U.S. Patent No.: 7,296,580, issued to Sbardella, discloses an apparatus 10 discloses a plurality of hair curlers 40 having means for engaging a hair curling appliance comprising a handle assembly 12 having curler engaging and disengaging means, a circuit for producing a volume of heated air, control means for energizing and de-energizing the circuit, an actuator for engaging a temperature burst and means for tapping a power source. The housing incorporates a handle assembly 12 containing a heating element for electrically heating the air in use, an on/off switch 24, quick release ring 26 and temperature burst button 20. At one distal end of the curling wand 12 is a curler attachment port 30 that allows the user to insert a curler 14 and release the curler by a quick release ring 26. The assembly 12 allows for the use of a variety of different size and style curlers 14. A storage case 38 is provided.

U.S. Patent No.: 7,040,021, issued to Talavera, discloses a hand held hair trimming device which when pulled through the hair trims only a determined portion of the ends of hair strands while leaving adjacent hairs uncut. The device will cut a predetermined length off only the distal ends of the hair shafts each time it has the hair drawn through one or a plurality of serpentine pathways formed by retainer cavities and an engageable retainer. The cutting head portion of the device may be removed and replaced and optional hair dryer or vacuum may be attached to an aperture on the rear of the cutting head to dry hair, vacate cut ends, or encourage distal ends of hairs toward the cutting blade.

U.S. Patent No.: 6,775,922, issued to Langley et al., discloses a hair dryer attachment system provides a dryer and a plurality of attachments. A fastening mechanism is provided so that multiple attachments are each securable to the generally circular or ovate dryer barrel using the same fastening technology. Each of the attachments forms part of the barrel, and when used with the preferred present shortened barrel, a so-called "standard-length" drier is provided which provides the additional benefits of the respective attachments, without being overly long so as to be cumbersome during use. Each attachment features an apron which is supported by the barrel and, with engagement formations on the barrel and complementary formations on the apron, the attachment is releasably secured to the barrel. Aeration barrel and finger/comb attachments are also provided.

U.S. Patent No.: 6,067,724, issued to Depoyian, discloses a hair drying assembly has a hair dryer that is particularly suited for using one of a plurality of interchangeable brush heads. The hair dryer has an ellipsoid shaped housing with a cylindrical outlet section at one end and a pivotal grip section at the other end. The handle is pivotally and removably attached to the housing. In one embodiment the handle is attached with air inlet passages formed by legs connecting to the housing and additional slots at the inlet end of the housing. Control buttons for regulating the motor are on the pivotal handle grip section. Outlet passages are provided in the outlet section. One form of brush head is hollow with peripheral openings and bristles extending therethrough and another brush head is solid with the bristles fixedly attached. In another embodiment there is a bifurcated handle with spaced arms that pivotally connect to the housing inwardly of the air inlet end.

The inventions heretofore known suffer from a number of disadvantages which include being limited in function, being limited in use, being limited in adaptabilities, being limited in interchangeability, being difficult to use, being expensive, being difficult to replace, being expensive to replace, being limited in application, being too bulky, being difficult to use, being more expensive over time, being difficult to upgrade, being single-use only, failing to perform both primary functions of a hair dryer (drying and heating), being inefficient, being heavy, having poor balance during use, requiring expensive repairs, failing to induce loyalty among consumers, having poor controls, and being fragile.

What is needed is a hair dryer that solves one or more of the problems described herein and/or one or more problems that may come to the attention of one skilled in the art upon becoming familiar with this specification.

MODE(S) FOR CARRYING OUT THE INVENTION

For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the exemplary embodiments illustrated in the drawing(s), and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.

Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.

Modules may also be implemented in software for execution by various types of processors. An identified module of programmable or executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be organized as an object, procedure, or function.

Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.

Indeed, a module and/or a program of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.

The various system components and/or modules discussed herein may include one or more of the following: a host server or other computing systems including a processor for processing digital data; a memory coupled to said processor for storing digital data; an input digitizer coupled to the processor for inputting digital data; an application program stored in said memory and accessible by said processor for directing processing of digital data by said processor; a display device coupled to the processor and memory for displaying information derived from digital data processed by said processor; and a plurality of databases. As those skilled in the art will appreciate, any computers discussed herein may include an operating system (e.g., Windows Vista, NT, 95/98/2000, OS2; UNIX; Linux; Solaris; MacOS; and etc.) as well as various conventional support software and drivers typically associated with computers. The computers may be in a home or business environment with access to a network. In an exemplary embodiment, access is through the Internet through a commercially-available web-browser software package.

The present invention may be described herein in terms of functional block components, screen shots, user interaction, optional selections, various processing steps, and the like. Each of such described herein may be one or more modules in exemplary embodiments of the invention. It should be appreciated that such functional blocks may be realized by any number of hardware and/or software components configured to perform the specified functions. For example, the present invention may employ various integrated circuit components, e.g., memory elements, processing elements, logic elements, look-up tables, and the like, which may carry out a variety of functions under the control of one or more microprocessors or other control devices. Similarly, the software elements of the present invention may be implemented with any programming or scripting language such as C, C++, Java, COBOL, assembler, PERL, Visual Basic, SQL Stored Procedures, AJAX, extensible markup language (XML), with the various algorithms being implemented with any combination of data structures, objects, processes, routines or other programming elements. Further, it should be noted that the present invention may employ any number of conventional techniques for data transmission, signaling, data processing, network control, and the like. Still further, the invention may detect or prevent security issues with a client-side scripting language, such as JavaScript, VBScript or the like.

Additionally, many of the functional units and/or modules herein are described as being "in communication" with other functional units and/or modules. Being "in communication" refers to any manner and/or way in which functional units and/or modules, such as, but not limited to, computers, laptop computers, PDAs, modules, and other types of hardware and/or software, may be in communication with each other. Some non-limiting examples include communicating, sending, and/or receiving data and metadata via: a network, a wireless network, software, instructions, circuitry, phone lines, internet lines, satellite signals, electric signals, electrical and magnetic fields and/or pulses, and/or so forth.

As used herein, the term "network" may include any electronic

communications means which incorporates both hardware and software components of such. Communication among the parties in accordance with the present invention may be accomplished through any suitable communication channels, such as, for example, a telephone network, an extranet, an intranet, Internet, point of interaction device (point of sale device, personal digital assistant, cellular phone, kiosk, etc.), online communications, off-line communications, wireless communications, transponder communications, local area network (LAN), wide area network (WAN), networked or linked devices and/or the like. Moreover, although the invention may be implemented with TCP/IP communications protocols, the invention may also be implemented using IPX, Appletalk, IP-6, NetBIOS, OSI or any number of existing or future protocols. If the network is in the nature of a public network, such as the Internet, it may be advantageous to presume the network to be insecure and open to eavesdroppers. Specific information related to the protocols, standards, and application software utilized in connection with the Internet is generally known to those skilled in the art and, as such, need not be detailed herein. See, for example, DILIP NAIK, INTERNET STANDARDS AND PROTOCOLS (1998); JAVA 2 COMPLETE, various authors, (Sybex 1999); DEBORAH RAY AND ERIC RAY, MASTERING HTML 4.0 (1997); and LOSHIN, TCP/IP CLEARLY EXPLAINED (1997), the contents of which are hereby incorporated by reference.

Reference throughout this specification to an "embodiment," an "example" or similar language means that a particular feature, structure, characteristic, or combinations thereof described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases an "embodiment," an "example," and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment, to different embodiments, or to one or more of the figures. Additionally, reference to the wording "embodiment," "example" or the like, for two or more features, elements, etc. does not mean that the features are necessarily related, dissimilar, the same, etc.

Each statement of an embodiment, or example, is to be considered independent of any other statement of an embodiment despite any use of similar or identical language characterizing each embodiment. Therefore, where one embodiment is identified as "another embodiment," the identified embodiment is independent of any other embodiments characterized by the language "another embodiment." The features, functions, and the like described herein are considered to be able to be combined in whole or in part one with another as the claims and/or art may direct, either directly or indirectly, implicitly or explicitly.

As used herein, "comprising," "including," "containing," "is," "are,"

"characterized by," and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional unrecited elements or method steps.

"Comprising" is to be interpreted as including the more restrictive terms "consisting of and "consisting essentially of."

Figure 1 is a side elevational exploded view of a hair dryer, according to one embodiment of the invention. There is shown a hair dryer 10 including a main body 12 having a handle 14 and a housing 16; the hair dryer 10 also includes a first module 20 and a second module 30 coupled to the housing 16.

The illustrated hair dryer 10 is configured to dry wet hair and assist in styling desired hair styles. The hair dryer 10 is configured to provide an interchangeable component hair dryer with interchangeable modules. The hair dryer 10 includes a main body 12 configured to support the modules and components disposed therein. The main body 12 includes a handle 14 and a housing 16.

In one non-limiting embodiment, there is a hair dryer made up of a plurality of separable but integratable parts, including but not limited to a heater, electronic controls, nozzles, main bodies, indicators, handles, blowers, and motors. One or more of the previous list may be permanently combined with one or more of the others of the list. One or more of the previous list may be selectably removable to one or more of the others on the list. One or more on the list may include mating structures for combining with one or more of the others on the list. One or more on the list may include communication structure(s) configured to communicate instructions, configurations, identification, and/or etc. to one or more others on the list. There may be one or more mounting points where one may add/remove various

modules/components/items from the list above. It may be that components may only attach/detach top/from a main body and not to each other, such that nozzles must be removed for a different nozzle to be applied, thus keeping the overall length, balance, weight, etc. of the device low/small/balanced during use/operation. It may be that components that tend to be very durable may be housed in the main body, while components that tend to have a shorter life cycle may be removable, thus decreasing operational expenses for consumers.

In operation, a user may attach/detach modules to a main body as desired from a selection of modules and/or main bodies. The modules may provide information while attached to the main body and the main body or other modules may use that information in the setup and/or operation of the hair dryer. The electronic components of the hair dryer may change one or more operational characteristics, including but not limited to power deliver, function of user buttons, function of indicators, and the like and combinations thereof and such may be in response to information provided by one or more modules. The user may then operate the combined hair dryer in a desired manner. Wherein one or more modules ceases to function or otherwise is no longer desired, it may be selectably removed and replaced with another module that may be a duplicate of the same or may have other characteristics. Figure 2 is a rear elevational view of a hair dryer main body exterior, according to one embodiment of the invention.

One of the illustrated receiving brackets 17 is asymmetrically placed so that the attached module may be properly aligned when coupled. The illustrated asymmetrically placed receiving bracket 17 also includes a communication device configured to mate with an associated structure on a module to be attached thereto so that the main body can "read" information from the module when it is so attached. The communication device may be simply a pair of electrical contacts shaped and positioned to come in contact with associated electrical contacts of a module to be attached so that when so coupled the main body and the module are in electrical communication. Receiving brackets I and/or 17 may also include one or more reusable power couplings to provide power to the module to be attached thereto.

Figure 3 is a side elevational view of a hair dryer, according to one embodiment of the invention. There is shown a hair dryer 10 including a main body 12 having a handle 14 and a housing 16 with various controls and indicators 21.

The first module interface structure 18 may include a first alignment structure that is configured to mate with a second alignment structure that is disposed on a first module and wherein mating of the first and second alignment structures result in functional alignment of a first module with the housing of the main body. The second module interface structure 28 may include a first alignment structure that is configured to mate with a second alignment structure that is disposed on a second module and wherein mating of the first and second alignment structures result in functional alignment of a second module with the housing of the main body. The hair dryer 10 may include a plurality of interchangeable second modules that may include varying operational characteristics.

According to one embodiment of the invention, there is a single dryer 10 with different replaceable heater and motor attachments options are provided. Since a heater attachment or motor attachment is much less expensive than a total dryer replacement, a stylist may purchase a dryer assembly and a backup heater and motor attachment. Further, different motor and heater attachment designs may be provided giving the stylist a broader range of dryer options by simply changing attachments.

Two basic drying modes are knockout and styling modes for drying hair. Each requires a different nozzle and heater configuration for optimum performance. While there may be many requirements, the two discussed here illustrate the point. There are also cases where a more powerful motor is required, but the larger a motor is, the heavier it is and the more expensive it is. By having a variety of motor attachments, a stylist may choose the lightest motor required thus keeping weight and noise to a minimum except when more power is required.

Another advantage of the modular approach is that the dryer body controls may be designed to recognize the type of nozzle being connected to it via a unique resistance value (that may be merely a resistor with mating contacts positioned to couple to a data structure of a main body when the module is coupled thereto) that may be read by control circuitry 19 of the dryer. As discussed above, typically less temperature is required for styling than for knockout. This may be accounted for by the dryer body controls. That is, when the dryer body control recognizes the resistance value for a styling nozzle, it may automatically re-program all of the temperature settings to reflect operating condition. Such may be accomplished according to preprogramed script, batch file, and/or a table of values stored in memory or the like or combinations thereof.

A motor or heater module may have its own unique code so the controller automatically operates whatever is plugged into it in one or more preprogrammed modes that may be configured to enhance the efficiency or other operational characteristics thereof. While a controller may be designed to recognize any number of heater and motor modules, there are other methods that may be used for recognition by the controller such as a series of jumper pins in the module, which act like programming dip switches and may operate in a purely physical manner during coupling instead of providing electrical communication.

It is also possible to program the dryer body controls for different hair types and dryer performance by inserting a micro-Flash drive into a drive reader slot in the body of the control. The drive may be functionally coupled to the control circuitry 19 of the hair dryer by a drive reader module coupled thereto. The drive may include instructions for altering operational characteristics of the hair dryer that may vary according to read characteristics of the attached modules. The micro drives may be sold separately and may be programmed to give a dryer almost any combination of heat and blow settings. These settings may be master controls for the lower level controls the blower and heater modules send to the controller to change the heating profile between the knockout heater and the styling heater.

For example, one could have a micro-Flash drive for fine hair, course hair, dry hair, etc. Each of these settings would have a subset of settings depending on which blower and/or heater module was installed. Microprocessor controls are often used in hair straightener products because straightener products use much less electrical power than professional blow-type hair dryers. When large amounts of electrical power is required by a blow-type hair dryer, larger, heavy-duty electronic components that often require special cooling consideration are required. This makes a blow-type hair dryer too large and heavy to be practical as do the special cooling requirements of said components.

There is shown a hair dryer 10 including a main body 12 having a handle 14 and a housing 16. The hair dryer 10 also includes a mating structure 23 configured to facilitate attachment to a module.

The illustrated hair dryer 10 is configured to provide different replaceable heater and motor attachments options. The hair dryer 10 includes a main body 12 having a handle 14 and a housing 16.

A system that pressurizes and moves a mass of air, such as a motor and blower in a hair dryer, generates mechanical waves that are oscillations of pressure caused by the mechanical means to generate said pressurized flow of an air mass. The magnitude and frequencies generated are a function of the type of design of the blower and motor and also the size of the motor and blower. For example a centrifugal blower with four blades of a certain diameter will generated different frequencies and magnitudes of oscillation than will the same blower with, say, six blades and a different diameter even though both designs may deliver the same air pressure and volume per unit time.

Generally speaking the larger the blowing mechanism can be to deliver a given flow and pressure the lower and smaller the oscillations of air pressure are. Generally speaking, lower frequencies are more tolerable than high frequencies and portray a sense of power.
