  According to the hair dryer of Patent Document 1, hair can be dried while spraying negative ions on the hair. However, since the negative ion outlet is limited to one central part of the brush unit, it is difficult to effectively attach negative ions to the hair, especially when the hair is long or the amount of hair is large. It takes a lot of time to get rid of moisture and moisturize.

  An object of the present invention is to provide a warm air dryer that can blow out negative ions from a plurality of locations of a brush unit, and thus can effectively attach negative ions to hair.

In the hot air dryer of the present invention, a hollow cylindrical main body case 1 is constituted by a wind tunnel portion 2 that houses a blower fan 6 and a heater unit 8 and a blowout portion 4 that houses an ion generator. The blow-out unit 4 is provided with a blower outlet 13 for sending dry air in a horizontal direction, and a brush unit 3 having a group of bristles 40 on the outer surface thereof is mounted. The ion generator includes at least two discharge electrodes 26 that are separately disposed along the longitudinal direction of the blowing portion 4, and a transformer 27 that applies a high voltage to both the electrodes 26. The outlet grille 14 covering the outlet 13 of the outlet portion 4, and the drying air delivery port 18, opened and two ion discharge port 17 provided corresponding to the respective discharge electrodes 26, two ion discharge port 17 is disposed separately at the center of the surface of the blow grill 14. The brush unit 3 is provided with a dry air outlet 44 and two ion outlets 46 provided corresponding to the discharge electrodes 26. When assuming a virtual region Z surrounded by the outline of each ion delivery port 46 and the circumscribed line connecting these outlines on the bristle planting surface of the brush unit 3, the bristle 40A is formed on the wall surface in the virtual region Z. It is planted. A drying air outlet 44A is opened on the wall surface in the virtual region Z adjacent to the bristle 40A. A dry air outlet 18A is opened on the wall surface of the blowing grill 14 facing the virtual region Z. The drying air outlet 44A of the brush unit 3 and the drying air outlet 18A of the blowing grill 14 are made to face each other.

  The present invention is characterized in that the following configuration is adopted in the hair dryer configured as described above. In the development view of the bristle planting surface shown in FIG. 1, when assuming a virtual region Z surrounded by the outer lines of the upper and lower ion outlets 46 and the outer tangent line connecting these outer lines, A bristle 40A is planted on the wall surface. Further, a drying air outlet 44A is opened on the wall surface in the virtual region Z adjacent to the previous bristle 40A.

  As described above, when the bristle 40A is implanted on the wall surface in the virtual region Z, the hair can be captured and swept by the bristle 40A formed between the upper and lower ion outlets 46. It is possible to eliminate clogging of each ion delivery port 46 by the hair bundle passing between 46 and to effectively attach negative ions blown out from the ion delivery port 46. In addition, it is possible to dry hair that passes between the upper and lower ion outlets 46 by blowing dry air from the outlet 44A that opens in the wall surface in the virtual region Z adjacent to the bristle 40A.

  Providing a pair of upper and lower discharge electrodes 26 in the blowing unit 4 can increase the amount of negative ions supplied as compared to the case where negative ions are generated by one discharge electrode, and negative ions are simultaneously supplied from two upper and lower locations. Even when the hair is long or the amount of hair is large, negative ions can be effectively and evenly attached to the hair, and the hair can be eliminated and moisturized in a short time. As described above, the blowout grill 14 is provided with the dry air outlet 18 and the two ion outlets 17. As shown in FIG. 4, the blowout grill 14 facing the virtual region Z is provided. The air outlet 18A for drying air is opened on the wall surface. Thus, by opening the dry air outlet 18A on the specific wall surface formed between the upper and lower ion outlets 17 and 17, negative ions can be prevented from adhering to the inside of the wall surface and being negatively charged. The amount of negative ions delivered can be increased by the amount that can be suppressed.

  Incidentally, when the ion delivery port is formed in an oblong shape that includes a specific wall surface and is vertically long, and the discharge electrode 26 faces the top and bottom of the ion delivery port, foreign matter can easily enter the blow grill 14 from the ion delivery port, The strength of the blow grill 14 is also reduced by the amount of the opening area of the ion delivery outlet. However, when the dry air outlet 18A is opened on the specific wall surface as described above, it is possible to prevent the strength of the blowing grill 14 from being lowered while preventing the entry of foreign matter.

  When the screw boss (projection) 20 is provided on the inner wall of the blow-out grill 14 facing the virtual region Z, the screw boss 20 can disturb the flow of the drying air flowing toward the discharge electrode 26 on the leeward side. The negative ions staying around the discharge electrode 26 can be forcibly blown off by the wind, and the inside of the specific wall surface can be well prevented from being negatively charged. This type of protrusion can be provided on the windward side of the discharge electrode 26 on the windward side, and if necessary, the flow of the drying air can be disturbed by a plurality of protrusions.

  The tip of the screw boss 20 is received and supported by the face wall (fixed wall) of the second loading portion 31 of the holder 23. Therefore, an external force acting on the blowing grill 14 can be borne on the face wall of the second loading portion 31 via the screw boss 20, and the strength of the front wall 15 of the blowing grill 14 can be improved accordingly.
