Detailed Description of the Invention

  The following preferred embodiments, as illustrated by the drawings, are for purposes of illustrating the present invention and are not intended to limit the invention as encompassed by the claims of this application. Devices and methods for heating a hair curler are disclosed herein.

  As shown in FIGS. 1-4, the curler heater 1 of the present invention includes an upper housing 1a typically having a diameter of 185 mm, and an intermediate housing having a diameter of typically 185 mm or 175 mm and a height of 35 mm. Shown is a body 1b, a lower housing 1c having a diameter of typically 175 mm. Silicon rings, typically O-rings, separate the housings from one another.

  As shown particularly in FIG. 3, the first silicon ring 2a separates the upper housing 1a from the intermediate housing 1b and others, and the second silicon ring 2b extends from the lower housing 1c to the intermediate housing 1b. Isolate. The screw 14 connects the housing.

  The heating display panel 3 is attached to the upper housing 1a. The display panel 3 may be one or more LEDs. Typically, this display panel 3 displays the sufficiency of heat applied to the curler by color code display. For example, a green color may indicate that the curler is sufficiently heated. Alternatively, red may be displayed when power is applied, and then green when the curler is sufficiently heated. Yet another embodiment may include a range of colors or a range of display light that indicates the temperature distribution achieved by the curler. For example, an indicator 13 that changes to four colors to indicate to the user how much heat energy the roller has left is used to make a predictable decision for hair styling purposes. When all four parts change color, the curler has reached its maximum temperature. The shining of the three parts may mean that the curler has reached 75% of the heat output. The two parts glowing can mean that the curler has reached 50% of the heat output. If only the final part shines, it may mean that the curler has reached 25% of the heat output.

  As shown particularly in FIG. 4, the coil frame 4 forms a well 4a designed to support a hair curler that is desired to be heated. The coil frame 4 also supports an induction coil including a wire winding around it.

  Attached to the lower housing 1c is an on / off switch 5 for applying power to the heater and disconnecting the connection.

  The wire coil 6 is wound around the coil frame 4 to create an induction coil. The wire coil 6 typically includes a wire insulated by a plurality of (for example, 20) enamels. The wire is typically 0.3 mm in diameter and twisted together and wound, for example, into a 100 mm diameter coil frame, typically having a thickness of 3 mm and a length of 63 mm. The number of turns around the coil can vary, but is typically 26-28.

The control circuit 7 is operably connected to the wire coil 6. The control circuit may typically be a printed circuit board. The printed circuit board includes:

  The micro switch 8 connects the control circuit 7 to the coil frame 4. The resonant capacitor 9 is disposed between the intermediate casing 1b and the lower casing 1c, and is operatively connected to the circuit board. The coil 6 is connected in parallel with the resonant capacitor 9 in order to create a resonant circuit. The heat sink 10 is accommodated in the lower housing 1 c and connected to the capacitor 9. Power for the heating unit 1 is supplied by a power cord connected to a suitable electrical connection 11 arranged in the lower housing 1c.

  FIG. 5 schematically shows the electrical system of the present invention. The present invention is mainly designed to control the on / off of a resonance circuit by an insulated gate bipolar transistor (IGBT). When driven by a resonant circuit, the inductor forms a high frequency alternating current. The change in current flowing through the inductor creates changing magnetic field lines, thereby forming a magnetic field. Eddy currents induced by the magnetic field lines are formed on the outer wall of the iron hair curler, and the electrical impedance of these eddy currents to the iron hair curler converts the electrical energy into thermal energy.

  FIG. 6 shows an exploded view of the hair curler 30 of the present invention for heating with the curler heater 1. The first conical member 12 has a slit 15 extending around it. Typically, self-grip tape is used on the first conical member 12 to grip the hair sufficiently so that the fine hair is not caught or torn off.

  The second conical member 16 fits substantially within the first conical member 12. The second conical member 16 is essentially composed of silicon. The third conical member 18 substantially conforms to the second conical member 16. The third conical member 18 includes a ferromagnetic material. The first end cap 20 conforms to the end of the first conical member 12 and has a substantially coaxial slit 22. The second end cap 24 conforms to the end of the third conical member 18 and also has a substantially coaxial slit 26 therein. The hair clamp 28 typically holds the hair wound around the hair roller. The hair clamp helps the hair roller retain heat and secure the roller in place.

  There are typically six sizes of hair curlers (26 mm, 32 mm, 38 mm, 46 mm, 52 mm and 58 mm in diameter). These are made of a stainless steel sheet having a thickness of 0.1 mm and a length of 60 mm. Each hair curler has a silicon film coated with nylon self-grip tape, typically 1-1.5 mm thick and added externally, and has an upper and lower portion coated with polycarbonate plastic. Each size of the roller is controlled by an insulator inside the roller and maintains the same temperature for the same period.

[Example]
It will be understood that the following examples of the invention are not intended to limit the invention, as more modifications can be made within the scope of the claims without departing from the spirit of the invention. I want.

  In operation, one embodiment of the present invention operates as follows. When the power supply is switched on and the two pole switches are in the on state, the power supply is in the on state indicated by a red display. When a large or small heat conduction heating curler is drawn into the well, the microswitch in the well is activated. If any ferromagnetic material is detected, the green lamp blinks, transmits an acoustic signal, and applies a high frequency alternating current to the inductor. A magnetic field is thus generated in the well. When a ferromagnetic material is present within the magnetic field, high frequency eddy currents are generated in the magnetic field. Under the influence of eddy currents, heat-conducting hair curlers containing ferromagnetic materials generate heat. The green lamp stops blinking and heating stops when the acoustic signal ends. The heat transfer hair curler can then be removed for use. The temperature rises slowly because high frequency eddy currents still remain in the heat transfer hair curler. When the temperature indicator begins to slowly change color (all four grids change color), the heat transfer hair curler can no longer heat until the four grids change to their first color. means.

  The total time for indicating whether the object in the well contains iron is typically 4 seconds. The total time for heating the curler is typically 4 seconds.

  With rapid and instantaneous heating of induction heating, the user places a curling roller in the heated well, waits for a total of 8 seconds, removes the roller and places another roller in the well in preparation for the next curly hair Make it possible to do. The present invention eliminates the risk of heating one roller at a time and placing the heated roller around. The roller is always freshly heated for styling.

  The induction of the present invention allows the roller to reach the maximum temperature immediately after the hair roller is applied, but not immediately thereafter. This provides the user with sufficient time to handle a gently heated roller instead of installing a hot roller.

  While the specific embodiments described and shown above are useful in many applications in the related heated hair styling techniques of the present invention, further modifications of the present invention will be apparent to those skilled in the art. . All such modifications are deemed to be within the scope and spirit of the invention as defined by the appended claims.
