BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dryer having a detachable attachment at an outlet, and in particular, for attaching / detaching an attachment, on / off and hot / cold air switching, and a variable resistor. It is intended to improve the operability of several kinds of operation buttons or knobs for adjustment.

[0002]

2. Description of the Related Art As a hair dryer equipped with several kinds of operation buttons or knobs, for example, Japanese Utility Model Publication 57-51.
As disclosed in Japanese Patent Publication No. 402, on the outer surface of the main body case that also serves as a grip, a switch button for switching on / off and hot / cold air, and a rapid cooling for switching to cold air by turning off only the heater when hot air is blown There are some buttons that are placed adjacent to each other. When the two or more types of operation buttons or knobs are collectively arranged on the outer surface of the main body case in this way, the hand holding the main body case can be grasped more than those arranged individually at separate positions. It is easy to operate with the fingers in the fixed position, and the operability is excellent.

[0003]

[Problems to be Solved by the Invention] However, in the case where the main body case is also used as a grip like this type of hair dryer, those operation buttons and knobs are operated by hand when setting hair, but as described above, When two or more types of operation buttons or knobs are collectively arranged on the outer surface of the main body case, the positions of the buttons or knobs may be mistaken for operation. However, if an operation button for attaching / detaching the attachment is further added and the operation button is arranged adjacent to the operation button, it is likely to be confused with misunderstanding. In particular, if the button for attaching / detaching the attachment is operated by mistake during hair setting, the attachment may come off the main body case, disturbing the hair setting or damaging the hair by dropping.

The present invention provides a hair dryer in which several kinds of operation buttons or knobs including buttons for attachment / detachment attachment / detachment are collectively arranged as described above. It is intended to prevent erroneous operations while ensuring operability by intensive arrangement by making ingenuity.

[0005]

According to the present invention, as shown in the drawings, a cylindrical main body case 3 also serving as a grip is provided with a suction port 8 at one longitudinal end and an air outlet 9 at the other longitudinal end.
A blower fan 7 and a heater 4 are arranged between the suction port 8 and the air outlet 9 inside the air outlet, and the outer periphery of the air outlet 9 is the main body case.

The button 33 for attaching / detaching the attachment, the switch button 38 for switching on / off and hot / cold air, and the rotary knob 36 for adjusting the variable resistor are collectively arranged on the outer surface of the main body case 3 in a straight line. With this, it becomes easy to put the hand holding the body case 3 in a fixed position and operate each with a finger. Even if the three types of buttons 33 and 38 and the rotary knob 36 are collectively arranged, each has a different operation form such as push, slide, and rotate, so that misidentification can be less likely to occur even during a fumbling operation. Of the three types of buttons 33 and 38 and the rotary knob 36, the button 33 for attaching / detaching the attachment, which is particularly likely to be pushed by the palm of the hand holding the body case 3 as it is and does not require operation during hair setting, is the body case. Even on the outer surface of No. 3, it is arranged close to the end portion on the outlet 9 side, so that careless operation during hair setting can be avoided as much as possible.

With the rotary knob 36 incorporated in the switch panel 37, its connecting boss 45 is fitted onto the operating shaft 44 of the variable resistor 35. Further, as shown in FIG. 4, the stopper claw 46 provided on the inner cylinder 36B is located outside the peripheral surface of the variable resistor 35, and by rotating the rotary knob 36, the stopper claw 46 is rotated by 180 degrees along the peripheral surface. It can be rotated and moved within a range. In order to regulate the rotation of the stopper claw 46, the left and right opening edges continuous with the inner peripheral wall of the mounting seat 48 are
That is, the rotation restricting portion 55 that defines the rotation start end and the rotation end of the claw 46 is provided at two locations facing the rotation area of the stopper claw 46.
Is formed. When the stopper claw 46 is in contact with the rotation restricting portion 55 on the rotation start end side, the rotation knob 36 moves to the position shown in FIG.
As shown in, the index 56 provided on the upper surface is set so as to point to a position corresponding to the low temperature end of the temperature range display 57 on the switch panel 37. From this state, turn knob 3
By rotating 6 in the counterclockwise direction, the amount of electricity supplied to the heater 4 is increased, and the amount of heat generated is gradually increased.
