Theelectrostatic atomization unit 12 has adischarge electrode 9 and anopposing electrode 10 and atomizes and electrostatically charges water drops supplied to thedischarge electrode 9 to thereby emit ion mist from anion outlet 11 disposed at a front side of thebranch channel 3. With this configuration, the cold air or the hot air can be ejected toward user from the hot andcold air outlet 6 while emitting the ion mist from theion outlet 11. - The
blower unit 7 has atubular body 7c accommodating therein amotor 7b and afan 7a which can be rotated by themotor 7b. An amount of an airflow of theblower unit 7 can be controlled by aswitch 16 provided at thegrip 14 in response to a maipulation of the user. Theheater unit 8 is provided at a downstream side of theblower unit 7. - The
heater unit 8 has an insulatingtubular body 8b accommodating therein abody 8a having a ceramic heater and the like. A flange 8c is provided at an end of the insulatingtubular body 8b. While the insulatingtubular body 8b accommodates thebody 8a, the flange 8c is contacted to anend 7d of thetubular body 7c accommodating thefan 7a and themotor 7b, and thenengagement pieces blower unit 7 and theheater unit 8. - The insulating
tubular body 8b may be deformed in an abnormal state. Therefore, in consideration of the reliability of the insulatingtubular body 8b, it is made of metal and is grounded to ahigh voltage board 18 through aground line 20. Power ON/OFF as well as temperature of thebody 8a can be controlled by theswitch 16 in response to a manipulation of the user. - The dual
tube type body 8b is provided with anotch 8f at an upper portion thereof. Thisnotch 8f is communicated with a notch 7f provided at an upper portion of thebody 7c when theblower unit 7 and theheater 8 are assembled. Further, acontrol board 19 and thehigh voltage board 18 driving theelectrostatic atomization unit 12 are disposed at an upper portion of the insulationtubular body 8b at two opposite sides of thenotch 8f without blocking thenotch 8f. Accordingly, when air is sucked from theair inlet 5 toward theairflow channel 2 by thefan 7a, the air is appropriately heated after passing through theheater unit 8, and, while the heated air is ejected from the hot andcold air outlet 6, a portion thereof also flows into thebranch channel 3. The air flowing into thebranch channel 3 passes through theelectrostatic atomization unit 12 and is emitted from theion outlet 11 while carrying the negative ions or the nano-sized ion mist. -
Fig. 4 is a perspective view of theelectrostatic atomization unit 12 showing an assembled state thereof, andFig. 5 is an enlarged cross sectional view thereof. Theelectrostatic atomization unit 12 includes a needle-shape discharge electrode 9, a ring-shape opposing electrode disposed in front thereof, and aPeltier device 12g for cooling thedischarge electrode 9. - A high negative voltage generated from the
high voltage board 18 applies to thedischarge electrode 9 through a resistor 30 (Fig. 1 ) for controlling the high voltage. It is preferable that theresistor 30 is disposed at an upstream side of thedischarge electrode 9. In this way, the generation of the negative ions or the ion mist can be prevented from being adversely affected by the potential of theresistor 30. - The
discharge electrode 9 is cooled by thePeltier device 12g so that moisture in the air is condensed at the tip of thedischarge electrode 9, and the high voltage discharge occurring between thedischarge electrode 9 and theopposing electrode 10 acts on the condensed moisture, enabling to provide large diameter nano-sized ion mist without supplying water. After mounting theelectrostatic atomization unit 12 as configured above on the insulatingtubular body 8b, amulti-perforation plate 17 having a plurality of holes is arranged in front thereof to prevent, while passing the ion mist therethrough, the foreign materials from getting into theelectrostatic atomization unit 12, to which the high voltage is applied, through theion outlet 11.

In themain wall 17, anotch 17b is provided so as not to cover theopposing electrode 10 of theelectrostatic atomization unit 12. Since themulti-perforation plate 17 made of an insulating material for allowing the ion mist to path through while preventing the foreign materials from getting thereinto is separately provided from theelectrostatic atomization unit 12 and has thenotch 17b, an amount of ion mist captured by themulti-perforation plate 12 can be decreased (charging themulti-perforation plate 17 can be difficult). - The
notch 17b is formed to have a width (W1) of, for example, 20mm corresponding to, for example, a width of theopposing electrode 10. Thenotch 17b is effective as long as part ofmain wall 17a is cut off not to cover at least a portion of theopposing electrode 10. For instance,notches 17b' can be provided at a plurality of places of a multi-perforation plate 17' as shownFig. 6 or at the side thereof as shownFig. 6 , without being limited to the top portion of themulti-perforation plate 17 as shownFig. 4 .

grip 14 also is assembled by fastening thescrew 4e after accommodating therein theswitch 16 and so forth between a pair of left andright cover grip 14, a boss 14c receiving thescrew 4e is inserted into a shaft hole 4f disposed at a bottom part of themain body case 4, so that it is possible to fold thegrip 14 as described above. The opposite end of thegrip 14 is configured such that thepower code 15 can be detachably installed thereat. - A
wire netting 21 is attached to a rear side of themain body case 4 through anattachment rim 22 and asuction inlet ring 23, thereby forming theair inlet 5. Similarly, awire netting 24 is attached to a front side of themain body case 4 through anoutlet ring 25, and anozzle 26 is detachably attached to theoutlet ring 25, thereby forming the hot andcold air outlet 6. Thesuction inlet ring 23 and theoutlet ring 25 are fixed to themain body case 4 byscrews outlet ring 25 and thenozzle 26 are separately provided, theoutlet ring 25 is hardly charged. - In the ion hair dryer 1 configured as described above, it is to be noted that the
nozzle 26 is inclined and tapered towards a leading end (i. e., opening) and a side of thenozzle 26 close to theion outlet 11 is inclined more than the opposite side thereof, such that anaxis 6a of the hot andcold air outlet 6 and anaxis 11a of theion outlet 11 diverge from each other. - In other words, the
nozzle 26 is tapered towards the opeing thereof. Further, in the vertical cross section as shown inFig. 5 , anupper part 26b of thenozzle 26 in the vicinity of theion outlet 11 is inclined downwards by θ2 degrees with respect to the direction of theaxis 11a along which the ion mist is emitted from theion outlet 11. On the contrary, alower part 26a of thenozzle 26 placed opposite to theion outlet 11 is inclined upwards by θ1 degrees with respect to the direction of theaxis 11a, wherein θ2 being greater than θ1. Therefore, a direction of theaxis 6a along which the hot of cold air is ejected from thenozzle 26 diverges from the direction of theaxis 11a. -
Axes 6a' and 11a' of the conventional ion hair dryer are arranged in parallel as shownFig. 7A . Therefore, the ion mist generated from an electrostatic atomization unit 12' is captured by an element located downstream of the electrostatic atomization unit 12', i.e., an upper portion of a main body case 4' molded by a resin, especially, a peripheral portion of a nozzle 26'. Accordingly, the ion mist subsequently supplied is repelled by the peripheral poriton of the nozzle 26', thereby preventing the ion mist from reaching a user. In contrast, theaxes Fig. 7A . Accordingly, the ion mist generated from theelectrostatic atomization unit 12 can reach the user efficiently. - Further, an inclined angle of the
axis 6a with respect to theaxis 11a is in a range from 12° to 30° so that the exiting ion mist can be ejected toward the user without great deviation and can reach the user efficiently. Though, theaxes axis 11a of theion outlet 11 in parallel with a main axis of the ion hair dryer 1 and inclining theaxis 6a of the hot andcold air outlet 6 with respect to the main axis, it is possible to align theaxis 6a of the hot andcold air outlet 6 in parallel with the main axis and incline theaxis 11a of theion outlet 11 upward. - While the invention has been shown and described with respect to the embodiments, it will be understood by those skilled in the art that various changes and modifications may be made within the limits of the claims.
