Abstract

A heating cooker includes heating chamber configured to house a food, through-hole formed in a wall surface of heating chamber, an imager configured to capture an image in heating chamber through through-hole, air blower configured to blow air on an outside of heating chamber, and wind guide configured to guide wind generated by air blower. Thus, wind guide is disposed so that the wind from air blower forms an air curtain passing through space between the imager and through-hole.

First claim

The invention claimed is:

1. A heating cooker comprising:
a heating chamber configured to house a food;
a through-hole formed in a wall surface of the heating chamber;
an imager configured to capture an image in the heating chamber through the through-hole;
an air blower configured to blow air on an outside of the heating chamber;
a wind guide configured to guide wind generated by the air blower, wherein:
the wind guide is disposed so that the wind from the air blower forms an air curtain passing through a space between the imager and the through-hole,
a portion of the wind from the wind guide goes into the heating chamber via the through-hole, and
a portion of the wind from the wind guide exhausts through an air duct and an air outlet;

a steam supply unit configured to supply steam, in the heating chamber; and
a discharge hole formed in the wall surface of the heating chamber to discharge the steam in the heating chamber to the outside of the heating chamber.

2. The heating cooker according to claim 1 , further comprising
an extension unit extending from an inner circumference of the through-hole toward the outside of the heating chamber.

3. The heating cooker according to claim 2 , wherein
a boundary between the extension unit and the wall surface of the heating chamber is curved outward.

4. The heating cooker according to claim 1 , wherein
the air blower is disposed below the imager, and
the wind guide is disposed to guide the wind from the air blower upward.

5. The heating cooker according to claim 1 , further comprising
a microwave supply unit configured to supply a microwave, in the heating chamber.
