Description

Heating elementary material of hair-iron for reducing heat transfer

The present invention relates to a heat generating structure of the iron for hair to reduce heat transfer. In particular, the present invention has a heat insulating layer made of a material such as air, silicon and heat insulating member and mica between the circuit coil that generates heat and the outer cover of the product which is in direct contact with the hand to transfer the heat generated from the circuit coil to the outer cover of the product. It relates to a heat generating structure of the iron for hair to reduce heat transfer.

Usually, hair iron is a beauty device for changing the hair style by converting electrical energy into heat energy of 60 ° C. to 210 ° C., which is a pair of product outer covers of which one end is hinged to face each other. It has a heat generating structure to heat the head inside.

In the hair pattern forming machine comprising a heater block having a heating member fixed to the elastic piece while being coupled to the other end inside, the heater block is a heater panel formed with a guide groove and the guide groove in the heater panel It is mounted to the housing in a floating structure including a heater frame (heater frame) is fastened and provided with a engaging projection protruding in the transverse direction at the upper end of the heater frame so as to overlap.

However, the 'hair pattern former' of the above-mentioned Utility Model Registration No. 20-0233945 (October 25, 2001) is a heater, although the heat generated from the heating member is transferred to the heater panel that substantially heats the head. There is a drawback that the hand may be burned in the process of changing the hairstyle by being transferred to the housing through the panel or through the heater frame.

An object of the present invention for solving the conventional drawback as described above is to provide an insulating layer made of a different material and an air layer that can block the conduction or convection of heat between the circuit coil to generate heat and the outer cover of the product exposed. When using a hair ironing to change the hair style, the outer cover of the product, which is directly held by the hand, is not excessively heated.

Hereinafter, the present invention will be described in detail.

Figure 1 shows a hair iron 10 according to the present invention, one side end of the pair of product outer cover 18 facing each other and each having a heating structure therein is hinged, a pair of products The outer cover 18 can be rotated at an angle about the hinge axis. The heat generating structure has a circuit coil for generating heat for transferring heat to the heater plate 13 that is exposed to the outside, and an air layer and a heat insulating layer for preventing heat generated from the circuit coil from being transferred to the frame.

2 and 3 show the main part including the heat generating structure 12 in the hair iron 10 shown in FIG. 1, wherein the heat generating structure 12 is formed on the pair of product outer covers 18, respectively. However, since the structures of the two heat generating structures 12 are identical to each other, only the heat generating structure 12 configured in one product outer cover 18 will be described.

The heat generating structure 12 has a container shape in the inside of the product outer cover 18, which is a skeleton of the hair ironing and directly touches the hand when changing the hair style, the material having a small thermal conductivity and elastic properties The heater cover 17 made of phosphorus plastic is incorporated.

The heater cover 17 is to fix the heat insulating layer 16 and the heater plate 13 made of the mica 16c, the heat insulating member 16b, the silicon 16a, and the like into the product outer cover 18. The fixed state is maintained in the product outer cover 18 so as not to be exposed to the outside of the cover 18. In the heater cover 17, a heat insulating layer 16, that is, a plate-shaped mica 16c, a heat insulating member 16b, silicon 16c, and the like are sequentially stacked. Of course, the heat insulating layer 16 is embedded in the heater cover 17.
