Definitions
- This invention relates to drying apparatus. More particularly,
- Conventional handheld hair driers typically comprise a cylindrical body or case with an air outlet at one end and an air inlet at the other.
- the drier incorporates an electric motor operated fan to provide an airstream through the casing together with an electric resistance heater such a nichrome wire element which disposed in the airstream adjacent the outlet.
- an electric resistance heater such as a nichrome wire element which disposed in the airstream adjacent the outlet.
- thumb controls for fan speed and air temperature.
- Such devices have been known for many years and are generally reliable in terms of operation and performance.
- One serious disadvantage however is the weight of such prior art driers which is caused chiefly by the inclusion of the relatively heavy fan motor in the handheld case. While this may not be so noticeable during occasional short term domestic use professional hairdressers who employ handheld driers for many hours each day find them laborious and tiring to use. This can leave an employer exposed to employee claims for strain injury.
- conventional handheld hair driers with the incorporated electric motor and fan are noisy and during use are held close to
- a hair drier apparatus which includes an air nozzle having an air inlet in communication with an air outlet, said nozzle being adapted for fan forced passage of air from said inlet to exit said outlet wherein a motive power unit is provided remote from said nozzle to power said fan forced passage of air, said motive power unit being operable from control means associated with said nozzle.
- said motive power unit is adapted for wall mounting.
- the air nozzle includes a heater through which the air passes before exiting said nozzle.
- control means are associated with said nozzle. It is further preferred that said heater is a resistance wire element located immediately upstream of said outlet.
- said heater is operable from said control means.
- said motive power unit is adapted to supply one or more air nozzles.
- figure 1 is an exterior schematic view of the motive power unit and end view of the air nozzle according to a first embodiment of said invention
- FIGS. 2 and 3 are side and rear elevation views of the air nozzle of figure 1,
- figure 6 is an exterior schematic view showing a motive power unit and end view of the air nozzle according to a second embodiment of said invention
- FIGS. 7 and 8 are cross-section side and rear elevation views of the handheld air nozzle of figure 6,
- FIGS 9 and 10 are exterior side elevation and plan views of the motive power unit of figure 6,
- FIGS. 1 1 and 12 are exterior schematic and cross-section elevation views of the motive power unit and air nozzle according to a third embodiment of the invention.
- FIGS. 13 and 14 are exterior schematic and cross-section elevation views of the motive power unit and air nozzle according to a fourth embodiment of the invention. DETAILED DESCRIPTION OF THE PREFERRED
- FIG. 1 there is an air nozzle indicated generally as 1 which is adapted for handheld operation as with handle 2.
- the nozzle/handle assembly includes an air inlet 3 with adjacent filter screen at one end which is in communication with an air outlet 5.
- An air passage is thereby defined in the nozzle from the inlet 3 through the filter screen to the heater 6 and outlet 5.
- the inlet 3 is connected to one of two supply outlets 7 in a remote wall mounted motive power unit indicted generally as 8.
- the connection is by means of a flexible conduit 9 and electrical control cables 10. These cables 10 connect with the heating element 6 adjacent the nozzle outlet 5 as well as a circuit board 1 1 within the motive power unit and control switches 12 on the handle 2.
- the motive power unit includes a suitably shaped housing 13 which is adapted for mounting to a wall or other convenient support structure (not shown) in a hair salon. It comprises a fan motor 14 fan blades 1 5, intake filter 16, electrical circuit board 1 1 and two air outlets 7 as mentioned earlier.
- the fan blades 15' are located within the air nozzle intermediate the inlet 3' and outlet 5' and upstream of the heater 6 ⁇
- the fan blades 15' are driven from a remote motive power unit with motor 14'.
- the drive is via a flexible rotating drive cable 17 of any suitable design.
- this drive cable 17 and the electrical control cables 10' are preferably encased in a common outer sheath.
- the remote motive power unit 8" is fitted with a mains power lead and plug 19. It may also be adapted to hang from a wall bracket 20 or the like.
- an electric motor and fan (not shown) of any suitable known design which is controlled through an electrical cable 10" extending from the fan motor to one or more switches 12" on the nozzle/handle assembly 1 ".
- an electrical cable 10" extending from the fan motor to one or more switches 12" on the nozzle/handle assembly 1 ".
- There is a flexible air conduit 9" extending from the base of the handle 2" to the underside of the motive power unit where it removably couples with a connector fitting 21.
- the electrical control cable 10" is encased within the wall of the conduit 9".
- the air flow 22 from the conduit 9" is turned by a cowling 23 at about 90 degrees and directed through a venturi type air multiplier 23 A whereby it entrains additional air 24 directly from an inlet 3" before exiting through a heater 6" and outlet 5".
- This arrangement has the effect of reducing the required air volume and pressure through the duct 9" while increasing flow at the nozzle outlet 5".
- the motive power unit 8' " comprises a direct plug- in 25 to a conventional mains power point.
- an electric motor (not shown) of any known suitable design which is controlled by an electric cable 10'" extending from said unit to one or more switches 12'" on the nozzle/handle assembly P " .
- the fan 15'" is mounted within the nozzle. It is driven by a rotating flexible drive cable 26 extending from said electric motor within the motive power unit 8'" to the nozzle.
- a movable cowling 27 which may be angled upwardly with respect to the direction of air flow 27A through the nozzle outlet 5" '.
- the cowling 27 is shaped to operate as a venturi type air multiplier which entrains additional air 28 into the flow directly from intake 3'" before exiting through a heater element 6' " and outlet 5'".
- the angle of the cowling 27 with respect to the direction of air flow 27A through the outlet 5'" may also be changed by sliding a lever 29 as indicated by arrow 30. This has the effect of changing the ef ⁇ iciency of the fan 15'" and thus the volume of air flow passing through the nozzle.
- This arrangement for varying the volume air flow may be in addition to or as an alternative to the electrical controls 12'" referred to earlier.
- nozzle/handle assembly While for simplicity of illustration only one nozzle/handle assembly is shown with each embodiment in use two or more may be fitted.
- the motive power unit may be mounted to a wall between two adjacent work stations. The flexible air ducts or drive cables would then connect the unit with individual handheld nozzles - one for each hairdresser. As the weight of the heavy fan motor is not carried in these nozzles they would be more agile, lighter and less tiring to use over a working day.
- the heating element may be incorporated into the remote motive power unit instead of the nozzle/handle assembly in accordance with design constraints.
- the heating element may be located either upstream or downstream of the fan.
- the motive power unit and heating element may or may not be controlled by hand operated switches on the nozzle/handle assembly.
- the control may also be remote or fully automatic and operable for example by pressure sensors, foot activated switches etc.
- the fan may be axial flow, as shown in the embodiments or centrifugal.
- the flexible drive may be of a general commercial standard or so designed to utilize modern materials to optimize its efficiency, reduce its maintenance and improve its flexibility.
- the hair drier is to have variable flow rate of air, this may be achieved by providing a multi speed motive power unit or by having multiple fan impellers engaged as required, variable pitch impeller or variable attitudes.
- variable flexible drive through the handle to the impeller within, it should be considered that the impeller may not be in the direct line of air flow, but that the impeller may be offset from the direct line of flow, and that the air intake and air outlet are ducted in such a manner within the casing to achieve the desired air flow and within this ducting arrangement that variable air flows may be achieved through flow divisions, valves etc.
- the hair dryer may incorporate a "Cold Shot” Button.
- the heating element may be traditional electric wire wound or any other suitable means It may be positioned within the hand piece or at a remote position.
