Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hair dryer with a brush that can optimally dry and set hair while supplying moisture to the hair using steam.

[Conventional technology]

In conventional hair dryers with brushes, hair is dried and conditioned using warm air, but over-drying damages the hair and does not sufficiently remove curls such as curls. Recently, a brush-equipped Ardryer with a steam generation function has been proposed. If you use this hair dryer with a brush, you can use steam to prevent the hair from over-drying and provide sufficient centrifugation.

[Problem to be solved by the invention]

Conventional hair dryers with a steam function dry hair using only hot air, and the user has to turn off the steam by flipping a switch, which makes them inconvenient to use.

Therefore, an object of the present invention is to provide a brush-equipped Ardryer that is easy to use.

[Means to solve the problem]

The brushed hair dryer of the present invention includes a housing provided with a brush surface having a discharge port and a suction port, a fan and a heater provided in the housing, and a steam generator provided in the housing that generates steam from the brush surface. The steam generating apparatus includes a generation mechanism and a moisture sensor provided on the brush surface to control the amount of steam generated by the steam generation mechanism.

[For production]

According to the brush-equipped hair dryer of the present invention, the amount of steam produced by the steam generation mechanism is controlled by a moisture sensor installed on the brush surface, and steam is automatically supplied according to the amount of moisture in the hair detected by the moisture sensor. can be done.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 shows an external view of a hair dryer with a brush.]O is a cylindrical housing having an air suction port 11 at one end and a brush 12 at the other end. The brush 12 may be integrated with the housing 1° or may be a detachable separate body. Bristle 14 is implanted on the brush surface 13 of the brush 12, and a discharge port I5 is formed on the brush surface I3. A fan (not shown) rotatably driven by a motor 16 (FIG. 2) is disposed within the housing 10, and pressurizes air taken in from the suction port 11 and discharges it from the discharge port 15. Further, a heater 17 (FIG. 2) is disposed between the fan and the discharge port 15,
The air taken in by the fan is heated and hot air is discharged from the discharge port 15. Further, a water tank 18 is detachably attached to the tip of the brush 12, and a steam heater 19 (see FIG. 2) is provided inside the brush 12, and water in the water tank 18 is supplied to the steam heater 19. A water absorbing body (not shown) is provided, and water heated by the steam heater 19 is blown out as steam from the discharge port 15 (or a dedicated steam outlet provided on the brush surface 13). In addition, these water tanks 18. Steam heater 19. The water absorbing body constitutes the steam generation mechanism. A moisture sensor 20 is installed approximately at the center of the blank surface 13. For example, the moisture sensor 20 has a pair of electrodes arranged adjacent to each other at a certain distance, a certain amount of hair is introduced between the facing surfaces between the two electrodes, and the moisture content of the introduced hair is measured. Configured to detect.

FIG. 2 shows the configuration of the electric circuit. The steam heater 19 is connected to the power plug 21 via the contact Sl of the power switch 22.
and triac 23 are connected in series. In addition, the power plug 21 has a contact point 5zSz of the IL source switch 22.
The voltage dividing resistor 24 and the bridge rectifier 25 are connected through the DC output terminal of the bridge rectifier 25.
is connected. Furthermore, the power plug 21 has contacts S + and S z of the power switch 22 and the switch 26
A hot air heater 17 is connected via the. A moisture detection control circuit 27 is connected to the gate terminal G of the triac 23, and a moisture sensor 20 and a display 28 are connected to the moisture detection control circuit 27.

The operation of the above configuration will be explained. Contact S of power switch 22
When , is turned on, steam is generated, and if the hair is guided between the electrodes of the moisture sensor 20, the moisture content of the hair is The moisture content is detected by the moisture detection control circuit 27 based on the capacitance or electric resistance value between the electrodes of the moisture sensor 20 corresponding to the amount of air or creeping moisture. As a result, when the wood fraction is below a certain level, the triac 23 is turned on and power is supplied to the steam heater 19 to generate steam, whereas when the moisture content is above a certain level, the triac 23 is turned off and the generation of steam is stopped. Therefore, when the hair has a low moisture content and is dry, steam is generated to supply moisture to the hair, and when the hair has a high moisture content and is wet, the steam is automatically stopped. In addition, the moisture sensor 20
If the moisture content between the electrodes is low and the moisture content remains low even after a certain period of time with the triac 23 turned on, the moisture detection control circuit 27 determines that there is no water in the water tank 18 and the display 28 or a buzzer or the like to notify the user of water absorption, and then the triac 23 is turned off to automatically stop power supply to the steam heater 19 to prevent dry cooking.

Next, when the contacts S I and S t of the power switch 22 are turned on, a voltage is applied to the motor 16 through the voltage dividing resistor 24 and the bridge rectifier 25, and the motor 16 is driven to rotate and enters a cold air discharge state. Further, when the switch 26 is also turned on, the motor 16 is driven to rotate as described above, and the power source is connected to the hot air heater 17, so that hot air is discharged. Here, moisture content detection and steam control are performed also during cold air and hot air.

With this configuration, when drying wet hair, when hot air is discharged, wet hair is introduced between the electrodes of the moisture sensor 20 by brushing, a high moisture content is detected, and the steam is stopped, allowing efficient drying. When the hair is dry, steam is generated to prevent over-drying and notify the user that the hair has finished drying.

Next, the hair cef) Sometimes the king because of dry hair.

It detects the low moisture content of your hair and generates steam, so it won't overdry, cause frizz, and won't damage your hair. In addition, if the steam is left in a state where it is generated for a long time, the electrodes of the moisture sensor 20 will become wet, so the steam will be automatically stopped to prevent the generation of excess steam and the water in the water tank 18 will run out. The steam generation mechanism will not be damaged due to being left unheated.

Furthermore, when the water tank 18 runs out of water and the steam generation mechanism is empty, the display 28 notifies the user to encourage water absorption, and also stops powering the steam heater 19 for a long time. It is possible to prevent damage to the steam generation mechanism due to idle firing over time.

In the above embodiment, the brush 12 was a blow brush, but the same applies to other brushes such as a roll brush.

It is also possible to control the phase of the triac 23 according to the amount of moisture in the hair detected by the moisture sensor 20 to increase or decrease the current flowing through the heater 19, thereby continuously adjusting the amount of steam generated.

〔Effect of the invention〕

According to the hair dryer with a blunt of this invention, the amount of steam produced by the steam generation mechanism is controlled by a moisture sensor installed on the surface of the blanket, and the amount of steam is automatically controlled according to the amount of moisture in the hair detected by the moisture sensor. supply,
This has the effect of improving usability.
