The upper layer 112 and the lower layer 114 are made of stainless steel so as to prevent rust and corrosion from occurring. And the conductive layer 120 may be made of aluminum to increase thermal conductivity to shorten the time consumed for heating and cooling.

At this time, it is preferable that the thickness of the conductive layer 120 is formed to be thicker than the thickness of the upper layer 112 and the lower layer 114, and is formed to have a relatively thin thickness of the upper layer 112 and the lower layer 114, For example, if the thickness of the conductive layer 120 is 6t, the thickness of the upper layer 112 and the lower layer 114 may be about 0.65t.

The heating plate 100 includes a conductive layer 120 having a relatively high thermal conductivity and an upper layer 112 and a lower layer 114 having a relatively low thermal conductivity on both the upper and lower surfaces of the conductive layer 120, It is possible to obtain an effect that the upper layer 112 to be heated can be heated evenly.

In addition, since the aluminum conductive layer 120, which has a high thermal conductivity but is relatively vulnerable to corrosion and hygiene, is not exposed to the outside, the probability of occurrence of rust and corrosion can be remarkably lowered.

The structure of the heating plate 100 can satisfy both heat conduction and heat preservation which are difficult to be compatible with one material, so that it takes a short time to heat the object to be cooked heated from the upper part and the heated contents are not easily cooled .

The front guide 210 is provided at its inclined surface with a discharge hole 240 formed to pass through the upper and lower portions and is formed at a position higher than the heating plate 100 so that before the oil or liquid used for cooking reaches a predetermined height, So that it is not discharged.

Also, the cooking byproducts generated during the cooking process can be selectively removed from the upper portion of the heating plate 100 by pushing them to the outlet 240.

A storage 300 in which the cooking byproduct removed from the heating plate 100 is stored in the lower part of the discharge port 240 through the discharge port 240 is shown in FIG.

Alternatively, the lower part of the outlet 240 may be connected to the outside by a duct so that the cooking by-product generated in the cooking process can be removed from the upper part of the heating plate 100 via the outlet 240.

The shape and position of the outlet 240 and the storage 300 are not limited to those shown in the drawings, but may be embodied in various shapes and positions according to the embodiment to which the present invention is applied.

The discharge port 240 may be provided so as to be openable and closable, and may further include a cover (not shown) covering and closing the discharge port 240.
