The general hair iron is composed of an upper body and a lower body, and both ends are composed of one body by hinge coupling, and the hot plate is provided at the ends of the hinged upper body and the lower body to face each other, and the heating plate is heated inside. The heater is provided.

The hair iron configured as described above drives the heater when the power is turned on to transfer heat of the heater to the hot plate. At this time, the hot plate is heated by the heat transferred from the heater. Using the heated hot plate, the user shaves the hair into waves or straightens them.

The hair iron is provided with a variable resistor for controlling the temperature of the heater, and by adjusting the resistance value of the variable resistor, the amount of power supplied to the heater is adjusted to adjust the target temperature of the heater. However, such a variable resistor has a problem that it is difficult to precisely control the temperature of the heater because the temperature change is changed significantly even a small change in the resistance value of the variable resistance when the temperature of the heater.

In addition, since the hair iron controls the driving of the heater based on the detected temperature of the heater despite the hot plate being in contact with the user's hair, the temperature of the hot plate cannot be properly controlled. Since heat cannot be applied, there is a problem that the molding completeness of the hair is low or the hair is damaged when the hair is formed.

An object of the present invention for solving such a problem is that the target temperature of the hot plate corresponding to the operation value of the operation unit and the heating temperature of the heating unit are stored so that the user can operate the operation unit more accurately and easily. It is an object of the present invention to provide a hair iron and a control method thereof.

Another object of the present invention is to provide a hair iron and a method of controlling the same, which can increase the degree of completeness of hair forming and prevention of hair damage by controlling the driving of the heating unit by sensing the temperature of the hot plate.

Technical means of the present invention for achieving this object, the heating unit; A hot plate that generates heat by the heating unit; An operation unit for operating a target temperature of the hot plate; A temperature sensing unit sensing a temperature of the hot plate; Blocking unit for blocking the heat of the heating unit to detect only the temperature of the hot plate in the temperature sensing unit; And a control unit for controlling driving of the heating unit by comparing the sensing temperature of the hot plate with the target temperature of the hot plate.

The power supply unit further supplies power to the heating unit, and the operation unit has a switch to turn on / off the driving of the power supply unit.

The blocking unit separates the heating unit from the temperature sensing unit to block heat from the heating unit from being transferred to the temperature sensing unit.

According to the technical method of the present invention, when the power-on and the target temperature of the hot plate are manipulated through the operation unit, the heating temperature corresponding to the target temperature of the hot plate is determined, the heating unit is driven, the temperature of the hot plate is sensed, The sensing temperature is compared with the target temperature and the driving of the heating unit is controlled based on the comparison result.

The sensing of the temperature of the hot plate detects only the temperature of the hot plate through a temperature sensing unit spaced apart from the heating unit.

According to the present invention, the target temperature of the hot plate corresponding to the resistance value of the variable resistor provided in the operation unit is stored in advance, so that the target temperature of the hot plate can be easily and accurately manipulated only through operation of one operation unit.

In addition, a power on / off switch is included in an operation unit that can control the temperature of the hot plate, thereby simplifying the temperature and power operation structure of the hair iron, and easily controlling power off or power supply control of the hair iron.

By sensing the temperature of the hot plate and controlling the driving of the heating unit, it is possible to increase the accuracy and completeness of hair shaping and to prevent hair damage.

That is, since the inner region of the heating plate in which the heating unit and the temperature sensing unit are installed is separated by the blocking unit, heat of the heating unit may be prevented from being transferred to the temperature sensing unit when the temperature is detected.

In this case, one area A is an area in which the heating unit 20 is installed, and the other area B is an area in which the temperature sensing unit 40 is installed. That is, the blocking unit 12 blocks the heat generated from the heating unit 20 from being transferred to the temperature detecting unit 40 so that the temperature detecting unit 40 directly detects only the temperature of the hot plate 10.

The hot plate 10 has a pair of guide members 14 formed on one surface thereof. The guide member 14 is a portion to which the cover 60 is coupled, and an outer side of the guide member 14 is provided with a locking portion 14a for stable coupling of the cover 60. In addition, a seating portion 14b for seating the elastic portion 50 is formed inside the pair of guide members 14.

The heating unit 20 is installed adjacent to the hot plate 10, and generates heat as current flows when power is applied. At this time, the heat generated from the heating unit 20 is transferred to the hot plate (10).

The insulating part 30 is mounted on the outer circumferential surface of the heating part 20 so that a current flowing in the heating part 20 does not flow to the outside. Here, the insulating portion 30 uses a polyimide (PI) tape having excellent electrical insulation. At this time, the heating unit 20 is wound several times by the polyimide tape.

The temperature sensor 40 is installed adjacent to the hot plate 10 to detect the temperature of the hot plate 10 and transmits the detected temperature of the hot plate 10 to the controller 120.

The elastic part 50 is mounted in the seating part 14b of the hot plate 10 such that the heating part 20 and the temperature sensing part 40 are not separated from the hot plate 10. 40).

Here, the operation value is a target temperature of the hot plate 10 desired by the user, and the heating temperature of the heating unit 20 for generating the hot plate 10 to the target temperature desired by the user is stored in advance.

Here, the operation unit 70 has a variable resistor. That is, the operation value of the manipulation unit 70 operated by the user is a resistance value of the variable resistor, and when the variable resistor is operated, the resistance value of the manipulated variable resistor is transmitted to the control unit 120.

At this time, the heating temperature of the heating part 20 corresponding to the resistance value of the variable resistor which is the target temperature of the hot plate 10 is preset. Here, when the heating temperature of the heating unit 20 corresponding to the target temperature of the hot plate 10 is set, heat is lost from the insulating unit 30 in the process of heat of the heating unit 20 is transferred to the hot plate 20. Set to take into account the heat lost due to loss in air. In addition, the heating temperature of the heating part 20 and the target temperature of the hot plate 10 may be the same.

And the operation part 70 is provided with the power on-off switch which supplies and cuts off power by user's operation. Accordingly, when the user wants to shape the hair, the user can operate the operation unit 70 to turn on the power, and when the hair molding is completed, the power can be turned off by operating the operation unit 70.

3 is a control block diagram of a hair iron according to an exemplary embodiment of the present invention, and includes a power supply unit 110, a control unit 120, and a storage unit 130.

The power supply unit 110 receives external commercial AC power and supplies driving power appropriate for driving each component.

The power supply unit 110 supplies or cuts off the power delivered to each component in response to a power on / off signal operated through the operation unit 10. The power supply unit 110 includes a rectifying unit (not shown) for rectifying the external commercial AC power to convert the DC power. And the power supply unit 110 supplies or cuts off the power delivered to the heating unit 20 according to the instructions of the control unit 120. That is, in response to a comparison result of comparing the target temperature of the hot plate 10 and the sensed temperature of the hot plate 10, the power supplied to the heating unit 20 is supplied or cut off.

The controller 120 is supplied with driving power from the power supply unit 110 when the power is turned on through the operation of the manipulation unit 10, and when the power is turned off, the driving power is cut off from the power supply unit 110.

If the resistance value of the variable resistor is transmitted through the operation of the operation unit 70 after the power is turned on, the controller 120 determines the target temperature of the hot plate 10 corresponding to the resistance value, and determines the target temperature of the hot plate 10. The heating temperature of the heating unit 20 corresponding to the determination is determined.

The control unit 120 controls the power supplied to the heating unit 20 so that the heating unit 20 is heated to a heating temperature, and when the sensing temperature of the hot plate 10 is transmitted from the temperature sensing unit 40, the heating plate 10 is heated.

Next, the operation unit 70 of the hair iron is rotated to turn on the power on / off switch, and the target temperature of the hot plate 10 is operated (201). At this time, the user manipulates the temperature of the hot plate 10 in consideration of the health state of the hair to be molded or the thickness of the hair.

Next, when external commercial AC power is supplied to the power supply unit 110, the power supply unit 110 rectifies the AC power to DC power and supplies the same to each component, and determines an operation value according to the operation of the operation unit 70. The target temperature is determined, and the heating temperature of the heating unit 20 corresponding to the target temperature of the hot plate 10 is determined.

Next, the heating unit 20 is driven 202 such that the hot plate 10 generates heat to a target temperature operated by the user. In this case, when the heating unit 20 is driven, the power supplied to the heating unit 20 is controlled so that the heating unit 20 is heated to a heating temperature.

Next, the temperature sensor 40 detects the temperature of the hot plate 10 (203), and compares the detected temperature of the hot plate 10 with the target temperature of the hot plate 10 (204). When the temperature of the hot plate 10 is detected, the temperature detector 40 is installed by the heating unit 20 and the blocking unit 12, so that the temperature of the hot plate 10 instead of the heating unit 20 is detected. The temperature of the hot plate 10 directly affecting the hair can be controlled to increase the degree of completeness of the hair molding, and can prevent hair damage.

When the sensing temperature of the hot plate 10 and the target temperature of the hot plate 10 are compared, if the detected temperature of the hot plate 10 is less than or equal to the target temperature of the hot plate 10, power is continuously supplied to the heating unit 20, and the hot plate When the detected temperature of 10 exceeds the target temperature of the hot plate 10, the power supplied to the heating unit 20 is cut off to stop the driving of the heating unit 20 (205).

Then, after cutting off the power supplied to the heating unit 20, the temperature sensing unit 40 continuously detects the temperature of the hot plate 10. When the sensing temperature of the hot plate 10 is less than the limit temperature, power is supplied to the heating unit 20 again to maintain the hot plate 10 at the target temperature. In this way, the hot plate 10 maintains the target temperature zone manipulated by the user, thereby enabling the user's hair shaping.

The limit temperature is a temperature lower by a predetermined size than the target temperature of the hot plate 10, and the limit temperature corresponding to the target temperature of the hot plate 10 is predetermined.

Next, it is determined whether the power is turned off through the power on / off switch of the operation unit 70 (206). In this case, when the power is not turned off, the heat plate 10 controls the power supplied to the heating unit 20 to maintain the target temperature of the heat plate 10, and when the power is off, the power supplied to each component is cut off (207). )

Such an operation unit 70 enables the operation of the target temperature of the hot plate 10 by changing the resistance value of the variable resistor according to the user's operation, and rotates the operation unit 70 to deviate from the minimum temperature. The negative power supply is cut off, and when the operation unit 70 is rotated again toward the lowest temperature, power is supplied to each component.
