デンサ、７６はファン用モータ、７７は電源である。In devices that measure air temperature, such as hair dryers, the air temperature remains A phase control type air temperature control device is used that can keep the air temperature constant and variably set the air temperature. for example,
As shown in FIG. 10, JP-A-59-156309 makes the air temperature constant by controlling the phase of a heater 70 with a triac 71 and controlling the conduction angle of the triac 71 with a positive temperature characteristic thermistor 72. Further, a variable resistor 73 is connected in series to the positive temperature characteristic thermistor 72 to variably set the air temperature. 74 is a bidirectional switching element that supplies gate current to the gate of the phase control element 71; 75 is a capacitor charged through the positive temperature characteristic thermistor 72 and variable resistor 73; 76 is a fan motor; and 77 is a power source.

頭髪を乾燥。However, this air temperature control device operates as follows when the resistance value of the variable resistor 73 is increased, for example, in order to lower the set temperature. That is, the conduction angle of the triac 71 becomes smaller - the temperature of the heater 70 decreases, and the air temperature also decreases. However, when the air temperature decreases, the temperature of the positive temperature characteristic thermistor 72 decreases.The resistance value of the positive temperature characteristic thermistor 72 decreases.→The conduction angle of the triac 71 becomes large.→The temperature of the heater 70 increases.The wind temperature increases. As a result, even if an attempt is made to change the set temperature by changing the resistance value of the variable resistor 73, the air temperature does not change much due to the action of the positive temperature characteristic thermistor 72.The same applies when increasing the set temperature.Therefore, this air temperature control The disadvantage of this device was that the variable range of temperature settings was small.And in the case of hair dryers,
Dry your hair.

がる、となる。The wind temperature stabilizing operation of the wind temperature control device 6 is such that when the wind temperature changes due to external factors such as ambient temperature or a decrease in air volume, for example, when the wind temperature increases, the temperature of the temperature sensor unit 10 increases. The resistance value of 10 increases - the conduction angle of phase control element 14 decreases - the temperature of heater 7 decreases, and the air temperature decreases.

The temperature of the air increases, and the air temperature remains constant. Conversely, the same applies when the wind temperature decreases.

い簡単な回路で前記作用効果が実現できる。Next, when setting the air temperature, the variable resistor 9 is operated. For example, when setting the air temperature low, the variable resistor 9 is operated.
The power of the heater piece 12 is increased by the operation - the air temperature in the vicinity increases - the temperature of the temperature sensor section 10 rises - the resistance value of the temperature sensor section 10 increases - the conduction angle of the phase control element 14 becomes small - - As the temperature of the heater 7 decreases, the air temperature also decreases. The same applies when setting the air temperature high. In this way, by heating the temperature sensor section 10 with the heater piece 9, a temperature difference can be created between the temperature sensor section 10 and the air temperature produced by the heater 7, so that the temperature variable setting means 28 can set the temperature over a wide range. Furthermore, the above effects can be achieved with a simple circuit with a small number of parts.

The outlet 31 of the wind tunnel 29 is located on the windward side near the temperature sensor section 10, and the operating section 32 of the shutter 30 protrudes from the main body 1. The other configurations are similar to the first embodiment.

温安定化動作は第１の実施例と同様である。In the wind temperature setting operation of this embodiment, for example, when increasing the set temperature, the operating section 32 is operated in a direction to increase the opening amount of the air hole 29a of the wind tunnel 29. Then, the amount of air passing through the wind tunnel 29 increases; the temperature sensor section 10 is cooled and its temperature decreases; the resistance value of the temperature sensor section 10 decreases; the conduction angle of the phase control element 14 increases; the temperature of the heater 7 increases. The temperature of the wind rises. To lower the set temperature, operate the operating section 32 in the opposite direction. By applying cooling air to the temperature sensor section 10 in this manner, a difference can be created between the temperature of the temperature sensor section 10 and the temperature of the air blown out from the discharge port 3, so that a wide range of temperature settings can be made. Note that the wind temperature stabilization operation is the same as in the first embodiment.

施例と同様である。This embodiment is suitable for a hair dryer or the like in which the air volume is adjusted by controlling the amount of current supplied to the motor 5, and the variable temperature setting means 28 is connected to the heater piece 12° variable resistor 9. The motor rotation speed setting means 33 includes a voltage dividing resistor 22 of the motor 5 and a switch. The heater piece 12 and the voltage dividing resistor 22 are arranged on the windward side near the temperature sensor section 10, and the variable resistor also controls the electric power of the heater piece 12, and the motor rotation speed setting means 33 sets the resistance value of the voltage dividing resistor 22. Set variably. Which voltage dividing resistor 22 is connected to the heater board 1) of the heater 7?
It is wrapped together with the heater 7. The rest is the same as the first embodiment.

第１の実施例と同様である。In this embodiment, the temperature sensor section 10 detects the temperature of the air heated by the heater piece 12 and the voltage dividing resistor 22. Therefore, even if the rotation speed of the motor 5 changes due to the operation of the motor rotation speed setting means 33 and the air volume changes, the partial voltage resistor 2
Since the amount of heat generated in 2 changes, the air temperature can be stabilized. In other words, if the voltage dividing resistor 22 is increased to reduce the amount of current flowing through the motor 5, the air volume will be greatly reduced. increases excessively due to the decrease in air volume, and discharge port 3
The temperature of the air blown out changes, that is, the change in air temperature varies with the change in air volume. However, in this embodiment, since the amount of heat generated by the voltage dividing resistor 22 also decreases at the same time as the air volume decreases, the temperature received by the temperature sensor section 10 decreases and the air temperature can be kept constant. The air temperature setting operation using the variable resistor 9 is the same as in the first embodiment.

果がある。According to this invention: 1. Separately from the temperature of the air heated by the heater and blown out by the fan, the temperature of the air from the fan is controlled by a temperature variable setting means, the air temperature is detected by a temperature sensor section, and the heater is controlled by a phase control element. Therefore, a stable air temperature can be obtained at the set temperature, and the temperature of the air heated by the heater can be varied over a wide range.
