Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a hair dryer, which has temperature control of 0-
Concerning things that have the ability to manipulate.

[Background technology]

In the conventional D hair dryer, as shown in Fig. 1, a temperature sensor (2
) were all installed, so temperature control (2)
It was only exposed to the hot air heated by the heater 111, and was isolated until it melted at room temperature. For this reason, the temperature ty"t-
The temperature of the wind (A) at a certain point in 121 is constant, but the temperature of the room temperature air coming in from the inlet (4) fluctuates as the room temperature changes, so the wind Q where there is no temperature There was a drawback that the temperature of the cell fluctuated depending on the room temperature as shown in Fig. 2.

[Purpose of the invention]

The present invention has been made in view of the drawbacks of the conventional examples described above, and the point where the hot air of the dryer comes out is Vcm degrees Celsius (positive temperature coefficient thermistor). The purpose is to compensate for changes in room temperature and prevent the hot air from moving even if the room temperature changes.

(2) is a positive characteristic thermistor, with a temperature of 2 F+01 and a positive characteristic of 3 star (2). It is installed on the leeward side of i11.Positive characteristic thermistor (
2) is completely fitted into the recess (++) at the tip of the metal heat conductor (3) and is brought into thermal contact, and the rear end of the heat conductor (3) is on the windward side of the heat conductor (3). It is extended to the room temperature and cooled, and is sandwiched by a thermal conductor (311d: a thermal insulator (1O)) and is insulated from the heat source 111. Therefore, the positive characteristic dimension -3 The star (2) not only detects the air temperature, but also the room temperature via the thermal conductor (3), feeds this to the circuit (7), corrects the air temperature based on changes in the room temperature, and adjusts the temperature of the air. It keeps the temperature constant.For example, when the room temperature is low, for example 10 degrees Celsius, the positive temperature coefficient thermistor (2) is cooled down, so the positive temperature coefficient thermistor (21) operates to raise the overall air temperature, and conversely, when the room temperature is high, for example When the temperature reaches 30℃, the PTC thermistor (2) is warmed up, so the PTC thermistor (2) works to lower the temperature, and as shown in Figure 5, even if the room temperature changes, the air temperature does not change. is kept constant.

The thermal conductor 131 shown in FIG. 6 is exposed on the outer surface of the dry cell case (13) and brought into contact with room temperature. In this embodiment, the heat conductor (3) can be touched, and by touching it with the hand (!), the air temperature can be changed according to the temperature of the hand.

In the one shown in FIG. 7, the heat conductor (3) is formed into a diagonal shape, and a positive temperature coefficient thermistor (2) is inserted into it to make contact.

A positive characteristic dimension - three star (2), one degree Celsius switch (9) and a temperature fuse (10) are installed on the leeward side of the Monokeshi one-star +11 shown in Figure 8, and the operating temperature is adjusted from the bottom in this order. This is a circuit diagram of the settings (phase temperature control circuit diagram).
The heater 111 and the positive temperature coefficient thermistor (2) are heat-insulated, and the air sent out by the fan (5) with a 61Vc seal is heated by the heater stream, and the temperature of the air is transferred to the positive temperature coefficient thermistor (2). 2) detects and outputs power to S

In Fig. 8, (Iφ is the power supply, 0η is the switch, (the country is the rectifier), (191 is the voltage dividing resistor, (to) 4 is the noise prevention capacitor, (21+122 is the noise prevention IF coil, +231 is the volume, pair) is the capacitor, 4271

The temperature is 0 to 100°C. When an abnormality such as f-darro-tsuk occurs, the power of the f--3 star (21) becomes 100 to 110°C, and the power of the stapler fi+ is turned OFF by phase control.

Due to this feature, the positive characteristic one mister (2) can be used not only as a temperature control device, but also as a neck device for preventing excessive temperature rise. tithe - seven sui 1 sui (9) operation point 1
The temperature is between 20°C and 10°C. Further, the operating temperature of the heating knee '1 (In) is 18'3±10°C. Thermal response is good because the operating temperature of the positive temperature coefficient thermistor (2) as an overheating prevention device is low, and because it is small and R11 can be placed near the temperature tll. Therefore, the phase control temperature control circuit using the positive temperature coefficient thermistor (2) as a temperature overrise preventer has good sensitivity. By using a phase control circuit using the positive characteristic dimension three star (21) to make the positive characteristic dimension three star (2) small and installing the VC near the illumination, it is possible to create a highly sensitive over-rise prevention formal wear neck.

This embodiment has a two-ton safety structure with a temperature switch, a temperature switch, and a temperature switch, but in addition, the temperature fuse can be prevented from blowing out by the action of a positive characteristic thermistor in the event of an abnormality such as when the switch is turned off. be.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to not only detect the wind temperature downwind of the heater D with a single mister of positive characteristics, but also detect the room temperature through the heat conduction plate, so that the temperature can be measured regardless of changes in the room temperature. It has the advantage of being able to remain constant.
