Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 According to this invention, the inside of the air passage of an electric hair dryer is divided into a hot air passage portion 1 and a cold air passage portion 2, and the cold and hot on-off valve 3 of each air passage portion is opened and closed to open the air. A device that changes the passage and can instantly switch between hot and cold air. The present invention relates to a device for an overheat prevention valve 3 in the warm air passage portion 1.

[0002]

[Prior art]

 A conventional electric hair dryer has a built-in electric heating coil inside one air passage. When the electric heating coil is hot, it is hot air, and when it is not hot, cold air and hot air are turned on and off by turning on and off the electric heating coil. Has been switched to. When alternately using hot air and cold air, it took too much time for the electric heating coil to cool, and it was difficult to switch between hot air and cold air immediately.

[0003]

[Problems to be solved by the device]

 When a substance is heated, it is likely to be deformed, and when it is cooled, it tends to harden, and so is hair. With a conventional electric hair dryer, you want to shape your hair with a comb or a hair brush, warm it with warm air from the hair dryer, and fix it with cold air. I kept holding it with a hair brush until it cooled down a little. It took a few minutes to a few tens of minutes to repeat the process and trim all the hair. Therefore, if there is a hair dryer that can be switched between warm air and cold air immediately and can be used continuously, warm it with warm air, fast, cool the hair and fix it. The desired hairstyle is finished in a short time. There has been a demand for electric hair dryers that can adjust the hair in a short time during the busy hours such as office workers before going to work in the morning.

[0004]

[Means for Solving the Problems]

 Explaining the structure now, the inside of the air passage is divided into each of the warm air passage portion 1 and the cold air passage portion 2, each air passage portion is provided with a cold / hot on-off valve 3, and the grip knob 7 is used to manually operate. Open and close. In addition, the hot air passage portion 1 is provided with an overheat prevention valve 4 for preventing overheating, and the heating coil 5 and the heating coil 6 are set so that one of the heating coils 6 supplies power to the auxiliary switch 11. I was able to stop it.

[0005]

[Embodiment of the invention]

 Next, to describe the embodiment and the embodiment of the present invention, the main power switch 10 is a four-stage changeover switch of a weak cold air, a strong cold air, a weak hot cold air, and a strong hot cold air. When the main power switch 10 is energized to the position of the mild hot / cold air when it is desired to use the weak hot air and the cold air, the fan motor 9 is rotated at a low speed to send the air, and the air passes through the hot air passage portion 1 and the heating coil. It is heated only by 5, and a weak warm air comes out from the tip 8 of the cylinder. When it is desired to change the warm air to the cold air, when the grip knob 7 is pressed, the cold / hot on-off valve 3 is activated to close the hot air passage portion 1 and open the cold air passage portion 2 so that the cold air immediately comes out. When the main power switch 10 is energized to the position of the strong hot and cold air when the hot air and the cold air are desired, the fan motor 9 is rotated at a high speed to send the air, and the air passes through the hot air passage portion 1 and the heating coil. 5 and the electric heating coil 6 heat the air, and a strong hot air comes out from the cylinder tip 8. Then, when it is desired to change the warm air to the cold air, the grip knob 7 is pushed, the cold / hot on-off valve 3 is operated, the hot air passage portion 1 is closed, the cold air passage portion 2 is opened, and a strong cold air immediately comes out. Further, one of the electric heating coils 6 is turned off by the auxiliary switch 11. When you want to use only cold air for a long time, when the main power switch 10 is set to weak cold air or strong cold air and electricity is turned on, the fan motor 9 rotates and air is sent to supply power to the electric heating coil 5 and the electric heating coil 6. Since the air is cut off, cold air comes out even when the air passes through the warm air passage portion 1. To prevent overheating of the warm air passage portion 1, when the warm air passage portion 1 closes and cools when the air is weak or strong, overheating occurs because the electric heating coil is energized. To prevent this, set the overheat prevention valve 4 It is provided. When the warm air passage portion 1 is closed, the overheat prevention valve 4 is opened at the same time, and a certain amount of air is passed to prevent overheating. Since the electric heating coil 5 and the electric heating coil 6 are energized during strong hot / cold air, the auxiliary switch 11 can be used only when the grip knob 7 is pressed in order to prevent it from overheating more easily than during weak hot / cold air. Electricity is cut off on one side of 6. Further, when the grip knob 7 is returned, the cold / hot on-off valve 3 closes the cold air passage portion 2 by the force of the spring 13, the warm air passage portion 1 opens, and the heating coil 5 is always energized to keep heat. At the same time, electricity enters the electric heating coil 6 and a strong warm air immediately blows out. As another example, if the Karl hair dryer is similarly improved, the same effect as described above can be obtained.

[0006]

[Effect of the invention]

 A conventional electric hair dryer has a built-in electric heating coil inside one air passage and switches between hot air and cold air when the electric heating coil is hot, and when it is not hot, cold air and electricity are turned on and off. . Therefore, it took too much time to heat or cool the electric heating coil, and it was not possible to immediately use hot air and cold air alternately and continuously. When you try to straighten your hair with a conventional electric hair dryer, make a hairstyle with a comb or a hair brush and warm it with warm air. I kept holding it until the hair cooled and the hair formed. Therefore, it took several minutes to several tens of minutes to prepare all the hair. Therefore, the electric hair dryer of the present invention can immediately use hot air and cold air alternately with continuous hot air and cold air as described in the above-mentioned embodiment of the invention, and as a way of using hair with a comb or a hair brush. The desired hairstyle can be easily completed in a short time by repeating the procedure of warming the hair with warm air, quickly cooling the hair, and fixing the hair. This is an effect of the idea that hairdressing can be done in a short time for people who have little time to work in the morning, such as office workers.
