This allows the operator to easily grip the upper case 11 and the lower case 12 when the hair is being groomed, while controlling and displaying the operation of the hair iron in the upper case 11 and the lower case 12. This is to secure a space for incorporating various configurations for the purpose.

3 is a perspective view showing an iron for hair according to the present invention, wherein a heater block 19 is mounted on a front portion of the upper case 11, and the heater block 19 is mounted on the upper case by a heater plate 13. 11) It is fixed inside. In addition, a heater block 20 is attached to the front portion of the lower case 12, and the heater block 20 is fixed in the lower case 12 by the heater plate 14.

A coupling piece 21 for coupling with the heater block 19 is formed upward in the heater plate 13, and a coupling piece 22 for coupling with the heater block 20 is formed in the heater plate 14. It is formed to be downward, and when the hair irons are assembled, the heater plates 13, 14 and the heater blocks 19, 20 are integrally combined to be mounted in the upper case 11 and the lower case 12. Can be.

In addition, two coupling grooves 23a and 23b are formed in the lower case 12, and coupling jaws 24a and 24b are formed in the heater block 20 to be coupled to the coupling grooves 23a and 23b. The heater block 20 can be mounted in the lower case 12 without using a separate fastening means such as a screw.

Here, the coupling groove 23b of the lower case 12 is open upward as shown in the drawing, which inserts the coupling jaw 24a of the heater block 20 into the coupling groove 23a of the lower case 12. After pressing the heater block 20 to insert the coupling tuck 24b of the heater block 20 into the coupling groove 23b of the lower case 12 to be fixed with the lower cover 26 coupled to the lower case 12. To do so.

Although not specifically shown in the drawing, the upper case 11 and the heater block 19 coupled thereto are also coupled to the engaging grooves 23a and 23b of the lower case 12 and the engaging jaw 24a of the heater block 20 ( By providing a coupling means similar to 24b), the worker can facilitate separate coupling of the upper case 11 and the heater block 19.

The PCB 27 is mounted in the rear portion of the upper case 11 in which the window 16 is coupled to the upper portion. The PCB 27, together with the LED 28 indicating the operation state of the hair ironing, and a circuit for controlling the overall operation of the hair ironing and the power supplied from the outside to the power supply suitable for the heater block (19) 20 A conversion circuit for converting may be provided.

A cover 25 for protecting the PCB 27 and the like embedded in the upper case 11 is screwed to the inner surface of the upper case 11 through two through holes 29 at the bottom of the upper case 11. It is joined by screws. In addition, the side cover 40, which is provided with a power switch 15 for controlling the power supplied to the heater blocks 19 and 20, is coupled to the side surface 39 of the upper case 11. Is coupled to the side face 39 of the upper case 11 in such a way that the coupling protrusion 41 of the side cover 40 is fitted into the coupling groove 42 formed in the side face 39.

In particular, as shown in the drawing, the engaging groove 42 of the side face 39 is opened downward, so that the engaging projection 41 of the side cover 40 is inserted from the bottom upwardly into the engaging groove 42 of the side face 39. Since the upper cover 25 is coupled to the bottom of the upper case 11, the side cover 40 together with the upper cover 25 is coupled to the upper case 11.

The lower cover 26 is screwed to the upper end of the rear part of the lower case 12 by screws screwed into the screw hole 30 of the lower case 12 through a through hole. The upper space of the lower cover 26 is an operating space which is a space in which the upper case 11 which is opened and closed at a predetermined angle about the hinge axis 33 and the spring 31 which provides the restoring force to the lower case 12 can operate. 34 is formed.

One end portion of the upper case 11 and the lower case 12 is provided with a plurality of support plates 35 and 37 for supporting the hinge shaft 33, and the support plates 35 and 37 have hinge shafts. Engagement holes 36 and 38 for engagement with the 33 and the oilless bearing 32 are drilled. The oilless bearing 32 and the spring 31 are fitted together with the hinge shaft 33 in the coupling holes 36 and 38 of the support plates 35 and 37.

Here, the oilless bearing 32 serves to reduce the load applied to the coupling hole 38 of the lower case 12, the support plate 37, which is opened and closed at a predetermined angle about the hinge axis 33 to a minimum, The plate-shaped spring 31 bent into a shape imparts a restoring force to the upper case 11 and the lower case 12 rotated to abut on each other by the user, so that the upper case 11 and the lower case 12 are intact. It serves to return you to the location.

Is coupled to the outer surface of the support plate 35, 37 while a plurality of hooks 43 formed on the inner surface of the cover 18 is coupled to the plurality of coupling grooves 44 formed in the support plate 35, 37 in a press fit manner Will be.

4 shows a coupling structure of the front part of the upper case 11 and the lower case 12 in which the heater blocks 19 and 20 are mounted, and the heater block mounted in the upper case 11 and the lower case 12. Since heat generated from the 19 and 20 is transferred to the heater plates 21 and 22, heat may be applied to the hair embedded between the heater plates 21 and 22.

5A and 5B show main parts of the upper case 11 and the lower case 12 that are opened and closed about the hinge axis 33, and the user presses and holds the upper case 11 and the lower case 12. 5A, the upper case 11 and the lower case 12 are rotated about the hinge shaft 33, and the spring 31 wound around the hinge shaft 33 is the upper case 11 and the lower case. It is retracted by the case 12.

On the other hand, when the user releases the hand holding the upper case 11 and the lower case 12, the upper case 11 and the lower case 12 by the restoring force of the spring 31 wound on the hinge shaft 33 Is returned to its original position as in FIG. 5B.

The above operation is repeated as the user presses or removes the pressing force of the upper case 11 and the lower case 12.

6A and 6B are circuit diagrams for driving control of an iron for hair according to the present invention, in which an operation control unit 49 that receives input power has a temperature sensor 45 built in each heater plate 13 or 14. The temperature of the heat generated by the heater blocks 19 and 20 by means of the 46, and when the temperature of the heater blocks 19 and 20 exceeds an arbitrarily set temperature, that is, 180 ° C., the heater block 19 ) To force the power to be supplied to (20). In addition, heat fuses 47 and 48 which are disconnected by high heat are formed on the heater blocks 19 and 20 driven by the control of the operation control unit 49, and the heater blocks 19 and 20 are overloaded. Is applied or heat is generated, the heat fuses 47 and 48 are automatically disconnected to cut off the power supplied to the heater blocks 19 and 20. Of course, even when an abnormality such as disconnection occurs in the heater blocks 19 and 20 itself, power is not supplied to the heater blocks 19 and 20.

In particular, the two heater blocks 19 and 20 are equipped with sensors 45 and 46, so that even if one of the heater blocks 19 and 20 is overheated, Power supply is cut off.

As described above, the present invention is a popular type having a simple configuration, and may selectively receive AC or DC power from commercial AC power, vehicle power, or a separate power supply to obtain heat required for hair care.

Although the present invention has been described in detail only with respect to the specific embodiments described, it will be apparent to those skilled in the art that various modifications and changes are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims of utility model registration. It is natural.
