問題点があった。Conventionally 1, in a small hair dryer, a plate-shaped T5
=Tux voltage divider resistor is used for voltage drop◎t
The Ramirix partial voltage resistor is formed by providing a resistor such as a resistor in a zigzag shape inside the resistor, and baking the periphery of the resistor with a t5 trix to form a plate shape. This has the advantage of being able to obtain a relatively large wattage from a thin and small size, so it fits in the small space of a small hair dryer. It has the advantage of not being a hindrance to electricity, but on the other hand, it has the characteristic of having low resistance at the moment a voltage is applied. Therefore, this is applied to the low voltage for driving the hair dryer fan.
When used as a voltage divider resistor for voltage drop, the voltage applied to the motor increases the moment the power switch is turned on, causing an overcurrent to flow at Tanabata.At the same time, the rotational speed becomes extremely high, causing Tanabata to drop. There have been problems such as an excessive load being applied, shortening the service life and causing breakdowns due to overcurrent, and an abnormally high rotational speed resulting in high noise, which can frighten the user.

This is the purpose.

In a hair dryer including a blower fan (2) and a driving motor M connected to an AC power source via a resistor fi+, the partial voltage resistor ftl has a positive temperature characteristic in which the resistance value increases as the temperature rises. The resistance value does not depend on temperature changes by combining the 3-meter resistor R2 with the NTC resistor R1, which has a negative temperature characteristic where the resistance value decreases as the temperature rises. be. As shown in FIGS. 1 and 2, in the case of unexamined examples, ceramics, snow, and NTC-9 were used.

H is a handle that can be folded compactly as shown by the dashed line A in the same figure. P is a power supply and C is a power cord. In the unexamined example, there is a temperature characteristic that is positive.
3 and NTC having negative temperature characteristics are connected in series with R1, and therefore cancel each other's temperature characteristics. Figure 4 shows the temperature characteristics of Sera + l, R, NTC, R1, and R1. A voltage dividing resistor whose resistance value changes little with temperature changes (
1) can be obtained, so as in the conventional example, the power switch
This eliminates the inconvenience of applying a high voltage to the °C-temperature M the moment W is introduced. Fig. 5 shows the change in rotational speed of the seventh motor M after the power switch SW is turned on for the unimplemented example, and Fig. 6 shows the change in the rotation speed of the seventh motor M after the power switch SW is turned on for the conventional example. - It shows the change in the rotation speed of the motor M. As is clear from comparing the two, in the conventional example, the moment the power switch SW is turned on, the seven-taper M rotates at high speed, making a loud noise and giving the user a sense of fear. Alternatively, there are problems such as shortening the life of the motor and causing failure, but in the unimplemented example, the rotation speed of the motor gradually increases as shown in Figure 5, as in the conventional example. No problems will arise.

０The uninvented device is constructed as described above, and includes a main controller that is connected to the AC power source when the power switch is turned on, and a blower fan drive that is connected to the AC power source via a voltage dividing resistor when the power switch is turned on. In a hair dryer, a resistor having a positive temperature characteristic whose resistance value increases as the temperature rises, and a negative resistor whose resistance value decreases as the temperature rises. It is combined with a resistor that has temperature characteristics so that the resistance value does not depend on temperature changes, so the resistance value of the voltage dividing resistor at the moment the power switch is turned on will not be much lower than in the steady state. Moreover, unlike in the past, the voltage at the Tanabata terminals at the moment the power switch is turned on does not rise to a particularly high level; This has the effect of eliminating inconveniences such as shortening the lifespan of Tanabata and causing malfunctions0.
