The cooking cavity is a cooking space for accommodating food and carrying out cooking and is provided with an inner plate 10 defining the cooking cavity and an inner space 30 formed between the inner plate 10 and the inner plate 10, And a shell plate (20) for covering the outer shell (25).

The inner plate 10 is composed of a lower surface and a side wall. The side wall of the inner plate 10 is bent downward to the outside of the cooking space and then upwardly extended to form the inner rim 61 and the outer rim 63, A recess 67 may be formed between the inner rim 61 and the outer rim 63 as a sharply projecting space.

As the material of the inner panel 10, SUS304 may be used, but it is not limited thereto. In addition, a second thermal conductive plate 15 may be attached to the lower surface of the inner plate 10, and the material of the second thermal conductive plate 15 may be aluminum or copper, but is not limited thereto.

The outer shell 20 is composed of a lower surface and side walls, and a plurality of ridges 35 are formed on the lower surface, and the plurality of ridges 35 may have a whirlpool shape. The plurality of swirl-like ridges 35 form a guide for the heat-conducting medium 25 received in the inner space 30 so that the heat-conducting medium 25 extends along the ridge 35 to the inner space 30 To rotate substantially horizontally and rotate rapidly.

The rapid flow and circulation of this thermal conduction medium 25 within the interior space 30 due to the plurality of swirling ridges 35 enables uniform heat transfer throughout the electric oil core skilllet 200 Thereby improving the heat transfer rate, shortening the cooking time, and reducing the energy required for cooking.

The outer sheath 20 may be made of SUS304, but may alternatively be made of 3-ply stainless steel, which may consist of three layers of AISI 304, Aluminum, and AISI 304 However, the material of the outside sheathing 20 is not limited thereto.

A first thermal conduction plate 40 may be attached to the lower surface of the shell plate 20 and the first thermal conduction plate 40 may be configured to conform to the shape of the ridge 35 described above , And when the ridge portion 35 has a spiral shape, the spiral shape can be matched. The material of the first thermal conductive plate 40 may be aluminum or copper, but is not limited thereto.

Preferably, the color of the heat reactive paint changes from green to yellow and red as the temperature of the container rises.

The heat conduction medium 25 accommodated in the inner space 30 between the inner plate 10 and the outer plate 20 may be silicone oil, but is not limited thereto. An electric heater 45, which will be described later, generates heat, which in turn heats the silicone oil, which in turn heats the inner plate 10, thereby cooking the food in the container accordingly. Even if the food is stored in the electric oil core skilllet 200 for an extended period of time, the silicone oil may have a thermal retention rate of at least 70%.

The heat conduction medium 25 may occupy 55 to 70% of the internal space 30 on a volumetric basis, and preferably occupies about 65% by volume. Further, the inner space 30 partially contains air.

The lid 90 is made up of an inner skin 92 and an outer skin 94, Lt; RTI ID = 0.0 > a < / RTI > A plurality of protrusions 93 may be formed in the inner skin 92 so that the steam inside the container hits the protrusions 93 and condenses into moisture to be collected in the recesses 67 described above.

As described above, since the container is composed of the double structure wall structure and the cover 90 has the double heat insulating cover structure, the heat in the container is prevented from being dispersed upward, , The inside of the container is maintained at a constant temperature for a long time. Thus, the food is automatically and slowly cooked, thereby preventing the loss of natural flavor, allowing self-cooking to be automatically cooked even if the heat source is removed.

In addition, once the thermal conduction medium 25 is heated, the thermal conduction medium 25 slowly transfers heat to the food over a long period of time. Thus, the flames of the heat source are not directly transferred to the inner plate 10, and this heat is not concentrated in any particular area, thus preventing food from being burned, partially heated or cooked. In addition, the container adds a more satisfactory and consistent texture to the cooking food while preserving the vitamins, nutrients and natural flavor.

Moreover, since not only the silicone oil but also the air stored in the inner space 30 serves as an insulator, the food is kept hot for a longer time and the thermal efficiency of the cooker is improved.
