is provided and detachably attached to the housing 1.

In addition, b in FIG. 2 is a rotating support shaft provided at the tip of the link plate 22, C is a support hole of this support shaft, and d is the switching lever so as to engage with the notch e at the other end of the link plate 22. 20, f is a drive hole for the control switch 23 of the heater g, and g is a slider for the rotation speed control switch 24 of the electric motor. It is attached to a blind hole.

Further, 18a is a window hole for forming a ventilation path to the intake port 4, which is provided in the guiding cylindrical portion 18 so as to be opened and closed by the vertical movement of the cylindrical clutch ring 14, and A in FIG. 1 is a razor portion A1. The storage chamber and opening of the drive motor 2 and its control switches 23 and 24 in the dryer section B indicates a chamber into which the iron section C can be freely accessed.

When using this as a razor in the above configuration, by rotating the switching lever 20 by a predetermined angle in the horizontal direction, the rod-like portions 17 at both outer ends of the clutch ring 14, which are constantly urged upward by the coil spring 15, By pushing up, the clutch shaft 13, which is also constantly urged downward by the coil spring 16, moves downward so that its lower end engaging portion 13a engages with the cylindrical engaging portion 3a provided at the upper center of the blower blade 3. The rotation of the electric motor 2 is transmitted to the rotating inner cutter 27 of the razor portion A via the blower blade 3.

At this time, the rotational speed of the electric motor 2 is controlled by operating the rotational speed control switch 24 in conjunction with the link plate 22, and by connecting a Zener diode 49 between the base of the transistor 48 and one terminal of the full-wave rectifier 51, As shown in Fig. 6, the output waveform of the rectifier 51 is cut off at its top and the input to the electric motor 2 is changed so that the speed is lower than that when operating as the other dryer, so that the rotational speed is optimal for the razor in question. The value is as follows.

On the other hand, when using this as a hair dryer, the clutch ring 1 is rotated by rotating the switching lever 29 in the opposite direction when used as a razor.
4 moves upward, the clutch shaft 13 and the blower blade 3 are disengaged, the rotation of the rotating inner blade 27 of the razor portion A is stopped, and the switch 23 is closed by interlocking the link plate 22. Heater 8 installed inside the wind barrel 7
is energized.

At this time, the rotation speed of the electric motor 2 is high because the circuit of the Zener diode 49 is opened, and a sufficient amount of air necessary for the dryer is provided, which is blown out from the discharge port 6 as hot air.

In this way, when the device is used as a hair dryer or as a razor, the rotation speed of the electric motor 2 and whether or not the heater 8 is energized can be automatically switched by simply operating the switching lever 20 described above. When in use, the clutch ring 14 is used to block the ventilation passage from the upper intake port 4 so that hot air does not come out from the discharge port 6 of the wind cylinder 7, and air is taken in only from the lower intake port 5. The thermostat 9, the voltage dividing resistor 10, and the electric motor 2 provided at the lower stage of the air conditioner 8 are cooled to prevent hot air from flowing out more than necessary.

Furthermore, when using this as an iron, as shown in FIG. 39, the iron base 28 is pushed out of the housing 1 so that it can be used as an iron.

In this case, as the iron base 28 protrudes forward, the interlocking changeover switch 38 operates so that the iron heater 29 is energized regardless of the control switch 23 of the heater 8.

When using Naeko as an iron, rotate the entire power cord bush 40 by 5180 degrees from the state shown in Figure 1.
A convex portion 55 provided on the bush 40 is fitted into a recess 56 provided on the rear wall surface of the housing 1, so that the cord 57 does not get in the way during ironing operation.

Further, as shown in FIG. 4, a temperature regulator 30 is provided near the ironing heater 29 so as to be operated by heat from both the ironing base 28 and the heat equalizing plate 31, so that the temperature of the ironing base 28 can be adjusted. I try to keep it constant.

In addition, a heat shielding cover 52 is detachably attached so that the iron can be stored in the housing 1 immediately after use, and an opening 53 is provided at the bottom of the heat shielding cover 52. When using it as a razor, hot air comes out directly from the outlet so that it does not hit the cheeks, for example.

Since the device of this invention is constructed as described above, for example, by operating the camshaft from outside the other housing of the hair dryer, the iron base inside the hair dryer can be protruded outside the housing for easy ironing. After use, it can be easily stored in the housing, making it convenient to carry when traveling or the like.
