Description

Touch Dryer {hiar dryer}

The present invention relates to a hair dryer, and more particularly, to a hair dryer using a sensor for sensing a touch signal.

The hair dryer is a home electric appliance in which a fan is attached to the shaft of a small-sized motor so that hot air is generated by a heater through a blower. Such hair dryers can be used to dry and mold hair using hot winds. As a kind of hair dryer, there is a hair dryer in the form of a hose in the pocket which is similar to the shape of a hat in order to make the hairstyle effective, which is a hair dryer which sends hot air from the hose.

Such a hair dryer requires the user's attention when using it. The reason is that when the hair dryer is used, the air heated by the heater comes out through the tuyeres, so that it can be burned by the heated air. Further, this heated air can easily ignite the surrounding flammable or combustible material.

Regarding the hair dryer requiring attention in such use, a user who uses a hair dryer generally uses a hair dryer with one hand and carries the user or another's hair with one hand. Therefore, There is a problem that it is inconvenient because the hair dryer must be operated or stopped.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a hair dryer which can control the driving of a hair dryer with only one hand.

Here, the touch sensor for sensing the touch signal may be located on the handle of the hair dryer.

Here, the sensor unit may be located at the center of the handle of the hair dryer.

Here, when the touch sensor senses the touch signal, the central processing unit may drive the motor and the heater.

Here, the central processing unit may stop driving the motor and the heater when the touch sensor is not sensed.

Here, the hair dryer may include a strength adjusting part capable of adjusting the strength of the motor and the heater by the user, and a main switch part capable of applying power to the hair dryer.

Here, the driving of the hair dryer can be controlled using a sensor for sensing a touch signal mounted on the hair dryer, and the user can control the operation of the hair dryer using the strength adjusting unit and the main switch.

According to another aspect of the present invention, there is provided a method of controlling a driving of a hair dryer, including: sensing a touch through a sensor for sensing a touch signal; converting the sensed touch signal into a voltage signal; A step of driving the motor and the heater, a step of determining whether or not the touch detection is released, and a step of stopping the driving of the motor and the heater according to whether or not the touch detection is released.

Here, in the step of sensing a touch through a sensor for sensing a touch signal, a touch signal may be generated when the touch sensor senses the touch signal.

The step of determining whether to release the touch sensing may include recognizing that the touch sensing is released when the touch sensing is released from the sensor for sensing the touch signal located at the handle.

Here, stopping the driving of the motor and the heater may include operating using a main switch.

According to the present invention, when using a hair dryer, the driving of the hair dryer can be controlled using a touch sensor, so that the driving of the hair dryer can be controlled with one hand.

In addition, the present invention has an effect that a user can control the driving of the hair dryer through a user's operation of catching the hair dryer to thereby facilitate the user's convenience.

In addition, according to the present invention, when the user does not stop driving the hair dryer, it is automatically turned off by not touching the sensor unit for sensing the touch signal, thereby preventing overheat or fire of the hair dryer.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a schematic view illustrating a hair dryer according to an embodiment of the present invention.

Referring to FIG. 1, a hair dryer according to an embodiment of the present invention includes a sensor unit, a control unit, a motor unit, and a heater unit.

Here, the sensor unit may include a sensor for sensing a touch signal.

Here, the hair dryer can detect the touch of the hand to the sensor that senses the touch signal when the user grasps or holds the handle. The hair dryer can recognize that the human hand is touched when the touch sensor detects the touch signal.

The touch signal sensed by the sensor for sensing the touch signal is transmitted to the voltage converter of the control unit, which will be described later.

The control unit includes a voltage converting unit, a central processing unit, a strength adjusting unit, and a main switch unit,

The voltage converting unit receives the signal received from the sensor unit that senses the touch signal, and can convert the voltage received from the sensor unit into a predetermined voltage that can be recognized by the central processing unit. The voltage converted by the voltage converting unit is transmitted to the central processing unit.

Further, the central processing unit receives the voltage from the voltage converting unit and can drive the motor unit and the heater unit according to the voltage. That is, the central processing unit can drive the motor unit and the heater unit when the sensor unit sensing the touch signal senses the touch of the hand.

The central processing unit can stop the motor unit and the heater unit when the touch signal is not sensed in the sensor unit for sensing the touch signal after the motor unit and the heater unit are operated.

The strength adjusting portion can be implemented with a slide switch and a rocker position for adjusting the strength of the motor portion and the heater portion. At this time, the intensity adjustment unit may be configured to provide different voltage values depending on the position selected by the user.

In addition, the main switch unit is formed to connect a power source for driving the hair dryer.

The motor unit can rotate the fan of the hair dryer by the voltage transmitted from the central processing unit to generate wind.

The heater unit may heat the wind generated by the motor unit so that hot air can be blown out from the hair dryer.

Hereinafter, a method of operating the hair dryer having the above-described configuration will be described.

First, the user can start driving the hair dryer by turning on the main switch unit. Here, the user can adjust the intensity of the motor unit and the heater unit at any time through the intensity adjusting unit.

Then, when the user grasps or grasps the handle, the touch sensor senses the touch signal of the sensor unit and transmits a signal to the voltage conversion unit.

Then, the voltage changing unit receives a signal from the touch sensor and outputs a voltage of about 0.6 V or less which allows the central processing unit to recognize the touch detection.

Here, the voltage changing unit can output a voltage of about 5V or more when the touch sensing is not performed by the sensor for sensing the touch signal.

Then, the central processing unit receives the voltage from the voltage converting unit and controls the driving of the motor unit and the heater unit. That is, when a touch signal is sensed by a sensor that senses a touch signal, the central processing unit drives the motor unit and the heater unit by a voltage of about 0.6 V output from the voltage conversion unit.

If no touch is detected by the sensor for sensing the touch signal, the central processing unit may stop the operation of the hair dryer. Here, the central processing unit may be configured to immediately stop the operation or to stop the operation with the main switch unit.

Further, even after the central processing unit stops operation, if the touch is sensed by the sensor unit, the central processing unit can drive the motor unit and the heater unit again.

2 is a view showing a state of a hair dryer according to an embodiment of the present invention. Referring to FIG. 2, in a hair dryer according to an embodiment of the present invention, a sensor capable of recognizing a touch signal may be located on a handle.

Preferably, the touch sensor capable of recognizing the touch signal is located at the side and center of the handle. Since the touch sensor is positioned as described above, the touch sensor can sense the touch at the same time only when the user grasps the touch. The user can operate the main switch portion and the strength adjusting portion located at the handle by the user, It can be used smoothly when used.

3 is a flowchart illustrating a driving control method of a hair dryer according to an embodiment of the present invention.

Referring to Fig. 3, first, the hair dryer is turned on by the user.

Then, the hair dryer determines whether the touch of the user's hand is sensed through a sensor capable of recognizing the touch signal.

Here, the hair dryer recognizes that a touch is detected when a touch is detected by a sensor capable of recognizing the touch signal.

Then, the hair dryer drives the motor and the heater when a touch is detected as a result of the judgment.

Then, the hair dryer determines whether or not the touch detection is released.

Here, the hair dryer recognizes that the touch sensing is released when the touch signal is released to the sensor capable of recognizing the touch signal.

Then, when the touch is released as a result of the judgment, the hair dryer immediately stops the driving of the motor and the heater.

Here, the hair dryer can be set to stop the driving of the motor and the heater immediately or also to the main switch portion.

Then, the hair dryer determines whether the power source is OFF,

If the power is turned off, terminate. In addition, the hair dryer may be in a standby state where the touch can be detected when the power is not turned off.
