Abstract
Description
- The present application claims priority under 35 U.S.C. §119 to Japanese Patent Application No. 2000-23780, filed Feb. 1, 2000, entitled “Hair Dryer”. The contents of that application are incorporated herein by reference in their entirety.
- 1. Field of the Invention
- The present invention relates to a hair dryer.
- 2. Discussion of the Background
- Conventionally, hair dryers have a pistol-like shape, i.e., a blowing part equipped with a fan and a heating device and a handle attached to this blowing part at a certain angle. These hair dryers usually have a two- or three-leveled switch to change the temperature of their blowing air, and such a switch is provided at their handles. Also, some hair dryers have a temperature controlling device designed to adjust the temperature of the blowing air. However, like the former hair dryers, such a temperature controlling device is provided also on the handles of those hair dryers. A user of the former hair dryers can select only two or three predetermined temperatures set by their manufacturers. A user of the latter hair dryers can adjust the temperature of the blowing air.
- However, because the temperature controlling device is on the handle, it would be difficult for her to adjust the temperature. For example, it is quite likely that she needs to free the temperature controlling device from her grip and either regrip or put the hair dryer into the other hand in order to make a temperature adjustment, particularly a fine adjustment.
- According to one aspect of the present invention, a hair dryer includes a main body, a heater, a fan, a handle and a temperature control device. The main body has an air outlet and an outer surface. The heater is encased in the main body and configured to heat the air. The fan is provided in the main body and configured to blow air toward the heater. The handle is attached to the main body. The temperature control device is configured to control the heater to adjust a temperature of the air and has a temperature adjuster provided on the outer surface of the main body between the air outlet and the fan. The temperature adjuster is configured to rotate around the outer surface of the main body to adjust the temperature of the air.
- A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:
- FIG. 1 is a side view of a hair dryer according to an embodiment of the present invention;
- FIG. 2 is a cross-sectional view of the hair dryer shown in FIG. 1;
- FIG. 3 is an enlarged side view of the adjustment device shown in FIG. 2;
- FIG. 4A is a perspective view of the temperature controller and the adjustment device shown in FIGS.1-3 in one state; and
- FIG. 4B is a perspective view of the temperature controller and the adjustment device shown in FIG. 4A in a different state.
- The preferred embodiments will now be described with reference to the accompanying drawings, wherein like reference numerals designate corresponding or identical elements throughout the various drawings.
- FIG. 1 is a side view of a hair dryer according to an embodiment of the present invention and FIG. 2 is a cross-sectional view of the hair dryer shown in FIG. 1.
- Referring to FIG. 1, a
hair dryer 3 has a main body 1 which is, for example, generally cylindrical, ahandle 2 extending from the main body 1 at angle and adetachable nozzle 13 attached on the front end of the main body 1. Thenozzle 13 may be fixed to the main body 1 or integrally formed as a part of the main body 1. Atemperature adjuster 5 is provided on the main body 1. On the outer surface of the temperature adjuster 5, a number ofelongated projections 28 are provided to ensure better gripping for a user. - Referring to FIG. 2, the main body1 accommodates a heater 6 and a blowing
device 11. The blowingdevice 11 includes amotor 8, aventilation fan 9 and fixedvanes 10 for streamlining air flow. At the front end of the main body 1, anair outlet 12 is provided to send the air heated by the heater 6 in the main body 1 to outside, and thedetachable nozzle 13 can converge the heated air before sending it to outside. At the rear end of the main body 1, anair intake 14 is provided to intake outside air into the main body 1. Thetemperature adjuster 5 is provided between theair outlet 12 and theventilation fan 9. Accordingly, the temperature adjuster 5 and the heater 6 may be easily electrically connected. - In the
handle 2, amain switch 15 for turning the hair dryer on and off, aflow rate selector 16 for choosing a certain flow rate from various flow rates, acool blow switch 17 for blowing cool air are provided. Also, anelectric cord 18 extends out from the bottom end of thehandle 2. - Inside the main body1, a
temperature detector 19, for example, a thermistor, is provided near the heater 6 and detects the temperature of the blowing air. Acontrol block 20 is provided inside thehandle 2. Thecontrol block 20 is designed to receive a signal from thetemperature detector 19 and control the electricity consumption of the heater 6. Further, thecontrol block 20 is electronically connected, for example, by lead, to avariable unit 21. In FIG. 2, thevariable unit 21 is positioned where thehandle 2 is connected to the main body 1. Thevariable unit 21 sets an amount of the electricity consumption by the heater 6. FIG. 3 is a side view of thevariable unit 21. - Referring to FIG. 3, the
variable unit 21 includes acircuit board 22, anadjustment contact 23 provided on thecircuit board 22 and alever 24. Thelever 24 has anadjustment controller 25 which is in contact with theadjustment contact 23. By making theadjustment controller 25 slide along theadjustment contact 23, theadjustment controller 25 alters the electricity consumption of the heater 6. Consequently, the temperature of the air heated by the heater 6 is adjusted. In addition, by operating theadjustment controller 25 along theadjustment contact 23 through thelever 24, thevariable unit 21 effectuates gradually progressive and regressive temperature control. Hence, the temperature of the air heated by the heater 6 can be finely adjusted. - FIGS. 4A and 4B are perspective views of a
temperature control device 50 including thetemperature adjuster 5 and thevariable unit 21 shown in FIGS. 1-3 in two different states. - Referring to FIGS. 1, 4A and4B, the
temperature adjuster 5 which has a ring-like shape is attached around the outer circumferential surface of the main body 1 and designed to rotate around the axis of the main body 1. On the inner surface of thetemperature adjuster 5, ahelical groove 26 winding with respect to the axis of the main body 1 is provided. Ahook portion 24 a on a tip of thelever 24 is slidably fitted in thehelical groove 26. Thus, when thetemperature adjuster 5 rotates around the axis of the main body 1, thehook portion 24 a of thelever 24 slides along thehelical groove 26 and thelever 24 slides in a direction substantially parallel to the axis of the main body 1. As a result, the adjustment controller 25 (see FIG. 3) slides along theadjustment contact 23 and alters the electricity consumption of the heater 6. The temperature of the air heated by the heater 6 is therefore adjusted. - In the embodiment described above, the shift ratio of the
adjustment controller 25 along theadjustment contact 23 to thehook portion 24 a along thehelical groove 26 may be 1 to approximately 3. For example, theadjustment controller 25slides 10 mm along theadjustment contact 23 as thehook portion 24 a slides approximately 30 mm along thehelical groove 26. By setting a shift ratio as such, theadjustment controller 25 and theadjustment contact 23 make a sufficiently fine alteration of the electricity consumption by the heater 6 to permit a fine temperature adjustment of the air heated by the heater 6. However, by making thehelical groove 26 longer, it is possible to make the temperature adjustment finer. - As described above, a number of the
elongated projections 28 are provided on the outer surface of thetemperature adjuster 5. Theseelongated projections 28 provide better gripping and easier adjustment for a user. For instance, theelongated projections 28 may be provided at an equal interval and each of theelongated projections 28 may have elongation substantially parallel to the axis of the main body 1. Hence, she can easily get hold of the temperature controller, turn it and adjust the temperature of the air without losing her grip. - According to the embodiment of the present invention described above, the
temperature control device 50 is designed to control the heater 6 to adjust a temperature of the air and has thetemperature adjuster 5 provided on the outer surface of the main body 1. A user can therefore adjust the temperature of the blowing air easily with one hand while holding on to the handle with the other hand. As a result, the user can continue to dry or style her hairs without awkwardly struggling or disrupting her drying or styling effort for the temperature adjustment. For example, according to the embodiment of the present invention described above, thetemperature adjuster 5 may have a ring-like shape and rotate with respect to the axis of the main body 1. Thus, the user can simply use her finger to operate thetemperature control device 50 from any part of thetemperature adjuster 5 and also easily reach and operate thetemperature adjuster 5 from any positions or directions when she moves the hair dryer around her head. - In the embodiment, although the
helical groove 26 is provided to guide thehook portion 24 a, any guide may be provided to guide thehook portion 24 a. For example, a step portion to guide thehook portion 24 a may be provided. - Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
