The power cord bushing is rotatably provided at the lower part of the rear wall of the housing 1 and has a cylindrical electrode 41 and a rod-shaped electrode 42 at the center. Contact plates 45 and 46 for internal leads are respectively provided at positions where these electrodes are fitted and are opposed to each other.

On the other hand, on the printed circuit board 47 on which the electric motor 2 is mounted, there is a transistor 4 for controlling the rotation speed as shown in FIG.
8, a Zener diode 49, a fixed resistor 50, and a full-wave rectifier 5i are attached, and these connections are made as shown.

Further, 52 in FIG. 1 indicates the discharge port 6 and the iron base 28.
This is a heat insulating cover that covers the front surface of the housing 1, and an opening 53 is provided on the lower side of the heat shielding cover, and it is detachably attached to the housing 1.

In addition, in FIG. 2, b is the rotation support shaft provided at the tip of the link plate 22, C is the support hole of this support shaft, and a is the above-mentioned switch to engage with the notch e at the other end of the link plate 22. An interlocking protrusion provided on the lever 20, f is a drive hole for the control switch 23 of the heater 8, and g is a slider for the rotation speed control switch 24 of the electric motor, which is provided on the link plate 22 together with the drive hole f. It is attached to the locking hole.

Further, 18a is a window hole for forming a ventilation path to the intake port 4, which is provided in the guiding tube 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 horizontally by a predetermined angle, each bar-shaped portion 17 at the outer end of the clutch ring 14, which is always urged upward by the coil spring 15, By pressing down, the clutch shaft 13 (which is always urged downward by the coil spring 16) moves downward, and its lower end retaining portion 13a connects to the cylindrical engaging portion provided at the upper center of the blower blade 3. 3a, and transmits rotation of the electric motor 2 to the rotating inner cutter 27 of the razor portion A via the blower blade 3.

At this time, the rotation speed of the electric motor 2 is controlled by operating the rotation speed control switch 24 in conjunction with the link plate 22, and by connecting a Zener diode 49 between the (-) side terminals of the base metal wave rectifier 51 of the transistor 48, a full wave 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 to make it slower than when operating as the other dryer, so that the rotational speed is the optimum value for the razor in question. This is how it should be.

On the other hand, when using this as a hair dryer, the clutch ring 1 is rotated by rotating the switching lever 20 in the opposite direction when used as a razor.
4 moves upward, the engagement between the clutch shaft 13 and the blower blade 3 is released, the rotation of the rotating inner blade 27 of the razor portion A is stopped, and the switch 23 is closed by the interlocking of the link plate 22, so that the air blower is released. A heater 8 provided inside the shell 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 used as a hair dryer and when used 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, and also when used as a razor. In this case, the clutch ring 14 is used to block the ventilation passage from the upper intake port 4 to prevent hot air from coming out from the outlet 6 of the wind barrel 7, and air is taken in only from the lower intake port 5, and the heater 8 The thermostat 9, the voltage dividing resistor 10, and the electric motor 2 provided at the lower stage are cooled to prevent hot air from coming out more than necessary.

Furthermore, when using these as an iron, as shown in FIG.
The protrusion 36 provided on the iron base 28 is pushed forward by the cam 39, and the iron base 28 is thereby projected outside 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 used as an iron, the entire power cord bushing 40 is rotated >'180 degrees from the state shown in FIG. The cords 57 are fitted together so that they do not get in the way during ironing operations.

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 the razor is used as a razor, hot air is directly discharged from the outlet 6 to prevent it from hitting the cheeks, for example.

Since the device of this invention is constructed as described above, it is possible to have a razor section, a hair dryer section, and an iron section in a single housing, which not only makes it convenient to carry, but also has an internal electric motor. The blower blades, etc. that are driven by this are designed not to inhale outside air from any other than the designated intake ports, which prevents dust from entering the housing, and especially when the iron section is heated, dust can cause ignition. It is possible to completely prevent accidents such as.
