## Abstract

A door is pivotably coupled to a lower portion or an upper portion on the front side of a box so as to be opened vertically to an opening. A gap having a predetermined space is present at the lower portion or at the upper portion between the box and the door with the door closed. The box has an aperture section on the side for introducing outside air blown by an air blower mechanism into a heating chamber. The aperture section is positioned adjacent to the gap on a side surface of the heating chamber. The outside air introduced into the heating chamber through the aperture section moves so as to traverse the opening to block vapor produced from an object being cooked by heating with a heating device from leaking through the gap to the outside of the heating chamber.

## Claims

### Claim 1

A cooking device comprising:
a box having an opening on a front thereof;
a heating chamber provided in said box and inside which an object to be cooked is placed through said opening;
a door for opening and closing said opening;
a heating device for heating the object in said heating chamber; and
an air blower mechanism provided in said box for blowing outside air to the periphery of said heating chamber for cooling, wherein
said door is pivotably coupled to a lower portion or an upper portion on a front side of said box so as to be opened vertically to said opening,
a gap having a predetermined space is present at the lower portion or at the upper portion between said box and said door with said door closed,
said box has an aperture section on a side thereof for introducing the outside air blown by said air blower mechanism into said heating chamber,
said aperture section is positioned adjacent to said gap on a side surface of said heating chamber, and
the outside air introduced into said heating chamber through said aperture section moves so as to traverse said opening to block vapor produced from the object by heating with said heating device from leaking through said gap to outside of said heating chamber.

### Claim 2 (depends on 1)

The cooking device according to claim 1, wherein said gap has said predetermined space larger than a length of thermal expansion of said box caused by heating with said heating device.

### Claim 3 (depends on 1)

The cooking device according to claim 1, wherein
said air blower mechanism includes a fan for blowing outside air and a deflector for deflecting the outside air blown from the fan, and
said deflector has such a shape that deflects the outside air blown by said fan to the upper portion or the lower portion of said box toward the side of said box and guides the outside air to said aperture section.

### Claim 4 (depends on 1)

The cooking device according to claim 1, wherein the cooking device is of a built-in type that is used such that said box is installed with its periphery covered.
