Abstract

A cooking device includes a casing, a heating chamber ( 102 ) provided in the casing and having an opening on a front side thereof, and a heat shield member ( 122 ) for blocking heat that transfers from the heating chamber ( 102 ) toward the casing. At least a part of the heat shield member ( 122 ) is located in a position that enables the heat shield member ( 122 ) to receive water droplets dropping through between the heating chamber ( 102 ) and the casing ( 101 ). The configuration reduces the possibility that a motor ( 133 ) and other components located below the heating chamber ( 102 ) fails by becoming wet due to condensate water.

First claim

The invention claimed is:

1. A cooking device comprising:
an outer casing;
an inner casing having a top wall, a bottom wall, front wall, back wall and side walls, the inner casing forming a heating chamber provided within the outer casing and having an opening on the front wall;
a heat shield member provided between the outer casing and the heating chamber to block heat that transfers from the heating chamber toward the outer casing;
a blower device arranged and configured to take in air from outside the outer casing and blow off the air into the outer casing; and
an air blow path provided in the outer casing, through which the air blown off from the blower device flows, wherein
at least a part of the heat shield member is placed below the heating chamber such that the heat shield member is allowed to receive water droplets dropping through between the heating chamber and the outer casing, and the cooking device has a structural arrangement such that
the air blow path includes a first space between said at least a part of the heat shield member placed below the heating chamber and a bottom of the heating chamber and a second space between said at least a part of the heat shield member placed below the heating chamber and the outer casing, wherein the heat shield member has a peripheral wall part provided between the inner casing and the outer casing and provided in a position that extends beyond a perimeter defined by the walls of the inner casing and facing a lower part of the side walls of the inner casing.

2. The cooking device as claimed in claim 1 , further comprising:
a drip receiver detachably mounted on a lower front side of the outer casing, wherein the heat shield member has:
a drain opening that is positioned over the drip receiver; and
a sloped surface continuous to the drain opening and sloped with respect to a horizontal surface, the sloped surface having greater heights on a side farther from the drain opening than those on a side nearer to the drain opening.

3. The cooking device as claimed in claim 1 , further comprising:
a high-frequency wave supply device supplying high-frequency waves into the heating chamber, wherein
the heat shield member has a cut-out part in which at least a part of the high-frequency wave supply device is accommodated.
