Description

[Detailed explanation of the idea] [Technical field of invention] This invention relates to improvements in hair dryers.

[Technical background of the invention and its problems]

Conventionally, hair dryers simply blow hot or cold air by operating a switch, and when in use, only the noise of the fan motor could be heard.

[Purpose of invention]

This invention was devised in view of these points, and the purpose is to provide a hair dryer that can be used while listening to a melody performance and allows comfortable hair styling and other tasks.

[Example of idea]

Hereinafter, embodiments of this invention will be described with reference to the drawings.

AC power supply 1, first on/off switch 2 and resistor 3
The AC input terminal of the full-wave rectifying diode bridge circuit 4 is connected through the AC input terminal. Further, a first heater 6 is connected to the AC power source 1 via a second on-off switch 5, and a second heater 8 is connected via a third on-off switch 7. A fan motor 9 is connected between the full-wave rectified output terminals of the diode bridge circuit 4. The fan motor 9
The motor 9 blows air by its rotation, and the heaters 6 and 8 are provided in front of the motor 9. Further, a step-down resistor 10 and a half-wave rectifier diode 11 are connected in series to the AC power supply 1, and further, first, second, and third music playing switches 12, 13,
A melody generating device 15 is connected through the melody generating device 14 in parallel, and a piezoelectric speaker 16 is connected to the output terminal of the melody generating device 15. The melody generating device 15 is composed of a commercially available melody IC, and plays different melodies of music by selecting the respective music playing switches 12, 13, and 14. The first, second, and third opening/closing switches 2, 5, and 7 and the first, second, and third music playing switches 12, 13, and 14 are provided externally,
It is energized by a switch button that is operated to switch between "OFF", "Cold air", "Mildly warm air", and "Strong warm air". When "OFF", all switches 2, 5, 7,
12, 13, and 14 are open, and when there is "cold wind", the first
opening/closing switch 2 and first music playing switch 12
is closed, the first and second open/close switches 2 and 5 and the second music play switch 13 are closed when there is a "weak temperature", and the first, second, and third switches are closed when there is "strong hot air". The open/close switches 2, 5, 7 and the third music playing switch 14 are closed.

In such a configuration, when the switch button is set to, for example, "cold air", the first opening/closing switch 2 is closed, and the first music playing switch 12 is also closed. Cool air is then sent out by the fan motor 9, and the melody generator 15 plays the first song through the piezoelectric speaker 16. Further, when the switch button is changed to, for example, "mild warm air", the first and second opening/closing switches 2 and 5 are closed, and the second music playing switch 13 is also closed. Thus, the fan motor 9 and the first heater 6 operate,
Warm air with a relatively low temperature is sent out. The melody generator 15 also plays the second song through the piezoelectric speaker 16.
to play through. Furthermore, when the switch button is changed to "strong hot air", all of the first, second, and third open/close switches 2, 5, and 7 are closed, and the third
The song play switch 14 is closed. Thus, the two heaters operate, and hot air with relatively high temperature is sent out. The melody generator 15 also plays the third song through the piezoelectric speaker 16.

Since a melody is played when the hair dryer is operated in this manner, hair styling and other tasks can be performed comfortably. Additionally, a different song is played each time the operation is switched between "cold air,""mildly heated air," and "strongly heated air," making work even more comfortable.

[Effect of idea]

As detailed above, according to this invention, it is possible to provide a hair dryer that allows you to work while listening to a melody performance, and allows you to comfortably set your hair.
