Abstract

A heating cooker includes a housing having a heating chamber defined therein, cooking dish support sections respectively provided on mutually opposed inner wall surfaces of the heating chamber to support opposite ends of a cooking dish in one of a plurality of vertically spaced support positions, a steam generating unit, and a steam ejecting portion having a single discharge port formed in an inner wall surface of the heating chamber and a steam passageway provided to guide the steam to the discharge port. The steam ejecting portion ejects the steam into the heating chamber through the discharge port. The single discharge port is provided in the inner wall surface confronting a space between the cooking dish supported in an uppermost support position of the cooking dish support sections and a ceiling surface of the heating chamber.

First claim

What is claimed is:

1. A heating cooker comprising: a housing provided with an inner casing having a heating chamber defined therein so as to open on a front surface and with an outer casing for covering the inner casing;
a door operable to open and close the heating chamber;
cooking dish support sections respectively provided on mutually opposed inner wall surfaces of the heating chamber to support opposite ends of a cooking dish in one of a plurality of vertically spaced support positions;
a water tank accommodating water therein;
a steam generating unit provided in a side wall of the housing between the inner casing and the outer casing to generate steam using water supplied from the water tank; and
a steam ejecting portion having a single discharge port provided in an inner wall surface of the heating chamber and a steam passageway having one end connected to an upper portion of the steam generating unit and the other end connected to the discharge port,
wherein a water supply pipe operable to supply water from the water tank to the steam generating unit and a drain pipe operable to drain water inside the steam generating unit are connected to a lower portion of the steam generating unit, and the single discharge port is provided in one of the inner wall surfaces confronting a space between the cooking dish supported in an uppermost support position of the cooking dish support sections and a ceiling surface of the heating chamber.

2. A heating cooker comprising: a housing provided with an inner casing having a heating chamber defined therein so as to open on a front surface and with an outer casing for covering the inner casing;
a door operable to open and close the heating chamber;
cooking dish support sections respectively provided on mutually opposed inner wall surfaces of the heating chamber to support opposite ends of a cooking dish in one of a plurality of vertically spaced support positions;
a water tank accommodating water therein;
a steam generating unit provided in a side wall of the housing between the inner casing and the outer casing to generate steam using water supplied from the water tank; and
a steam ejecting portion having a single discharge port provided in an inner wall surface of the heating chamber and a steam passageway having one end connected to an upper portion of the steam generating unit and the other end connected to the discharge port, wherein the steam passageway of the steam ejecting portion comprises a single pipe having one end connected to the steam generating unit and the other end connected to the single discharge port, and
wherein a water supply pipe operable to supply water from the water tank to the steam generating unit and a drain pipe operable to drain water inside the steam generating unit are connected to a lower portion of the steam generating unit, and the single discharge port is provided in one of the inner wall surfaces confronting a space between the cooking dish supported in an uppermost support position of the cooking dish support sections and a ceiling surface of the heating chamber.
