A steam oven including an outer casing to define an appearance of the steam oven, an inner casing provided in the outer casing to define a cooking cavity to cook food therein. The inner casing includes an inner wall and an outer wall, with a space defined between the inner wall and the outer wall and maintained in a vacuum state, thus insulating the cooking cavity from an outside of the inner casing. The steam oven further includes a steam generator to supply steam into the inner casing. Therefore, the steam oven accomplishes the desired insulating effect without using any insulating material while the space defined between the inner wall and the outer wall reduces conductive and convective heat transfer.

A steam oven, comprising: an outer casing to define an appearance of the steam oven; an inner casing in the outer casing to define a cooking cavity to cook food therein, with an empty vacuum layer provided in an interior of a wall defining the inner casing; and a steam generator between the outer casing and the inner casing to supply steam into the inner casing. 7. A steam oven, comprising an inner casing having a cooking cavity to cook food therein an outer casing, and a steam source external to the inner casing, the inner casing, including an inner wall and an outer wall, with an empty vacuum maintained between the inner and the outer walls to insulate the cooking cavity from an outside of the inner casing, including the outer casing. 8. The steam oven according to claim 7, further comprising: a front panel in a front of the outer casing, wherein the inner wall and the outer wall of the inner casing are coupled to the front panel and separated from each other. 9. The steam oven according to claim 8, further comprising: an inner surface of the front panel; and an elastic seal between front ends of both the inner wall and the outer wall of the inner casing and the inner surface of the front panel to seal a junction between the front ends of both the inner wall and the outer wall of the inner casing and the inner surface of the front panel. 10. The steam oven according to claim 9, further comprising: a flange to extend from the front end of each of the inner wall and the outer wall of the inner casing to be parallel with the front panel; and a fastener to fasten each flange to the front panel, respectively, with the seal elastically deformed between the flanges. 11. The steam oven according to claim 7, further comprising a steam generator to supply steam to the steam oven, wherein the steam generator comprises: a steam generating vessel having an outlet connected to and communicating with the cooking cavity, with a predetermined amount of water contained therein; a first heater, to generate steam, installed in the steam generating vessel; and a second heater to overheat the steam generated by the first heater. 12. A steam oven, comprising: an inner casing having a cooking cavity to cook food therein, including an inner wall and an outer wall, with an empty space defined between the inner and outer walls, which is maintained as a vacuum, to insulate the cooking cavity from an outside of the inner casing; and a steam generator between the outer casing and the inner casing to supply steam to the cooking cavity. 13. A sealing apparatus to maintain a vacuum in a casing of a steam oven, comprising: an inner casing having a front opening including an inner wall and an outer wall separated from each other; a front panel to border the front opening; a seal between each of the inner wall and the outer wall and the front panel to maintain an empty vacuum between the inner wall and the outer wall; an outer casing; and a steam generator between the outer casing and the inner casing. 14.
