The inner container member 110 may be formed of a material capable of induction heating as a whole. Here, the material capable of induction heating may be formed of, for example, an iron (Fe) based material, an iron (Fe) based alloy, a magnetic material, a ceramic having conductivity, or the like.

Here, if the inner container member 110 is formed of a material capable of induction heating, the inner container member 110 can be heated regardless of the position of the coil for induction heating in the induction, so that it can be used in various kinds of induction Do.

For example, since the induction applied to the electric pressure cooker requires heating within a short time, a coil for performing induction heating is provided around the container. In a conventional induction, a coil for performing induction heating is installed on the bottom, May be different.

The inner container member 110 may also include a coating layer 140.

The coating layer 140 may be positioned on the inner surface of the inner container member 110 to prevent the object to be contained in the inner container member 110 from being stuck by heating.

The coating layer 140 may be formed on the inner surface of the inner container member 110 in which the object to be heated is contained. The coating layer 140 may be formed of a material such as ceramic, fluorine resin, Or may be formed in a form in which two or more different materials are stacked and overlapped.

1 to 3, the vacuum container 100 for induction according to the embodiment of the present invention may include an outer container member 120.

The outer container member 120 has a larger size than the inner container member 110 to accommodate the inner container member 110 and may be formed in a shape corresponding to the inner container member 110.

The inner container member 110 accommodated in the outer container member 120 can be accommodated away from the outer container member 120.

Unlike the inner container member 110, the outer container member 120 may be formed of a material that is not induction-heated, such as a metal, synthetic resin, or ceramic that is not included in the iron (Fe) system.
