Abstract

Provided is a heating cooker that can efficiently apply steam to the entire food and can also cook the food quickly. A heating cooker (1A) includes a toasting grill (16) provided within a cooking chamber (10) and a lower heater (17b) provided at a lower section within the cooking chamber (10). Steam is blown between the toasting grill (16) and the lower heater (17b) from a steam outlet (25) provided in at least one sidewall of the cooking chamber (10).

First claim

The invention claimed is:

1. A heat cooking device comprising:
a food placement section provided within a cooking chamber;
a lower heating member that is provided at a lower section within the cooking chamber and that heats food placed on the food placement section from below;
a steam generating unit that has a steam outlet in at least one sidewall of the cooking chamber and that blows steam between the food placement section and the lower heating member from the steam outlet,
and a steam guide that is provided at a position below the steam outlet and that guides the steam, which is blown out from the steam outlet and travels downward, between the food placement section and the lower heating member, wherein the steam guide has a flat surface extending horizontally from a bottom rear wall toward a front of the cooking chamber.

2. The heat cooking device according to claim 1 ,
wherein the steam generating unit has a steam ejection port that ejects the generated steam outward from the heating cooker and that is installed in alignment with the steam outlet.

3. The heat cooking device according to claim 1 ,
wherein the food placement section includes a cooking grill on which the food is placed,
wherein the cooking grill has a first metal wire group in which a plurality of first metal wires are arranged and a second metal wire group that is provided on the first metal wire group and in which a plurality of second metal wires are arranged, and wherein the first metal wire group and the second metal wire group constitute a grid-shaped section, and
wherein an opening ratio F in the grid-shaped section expressed by expression (1) indicated below is 70% to 80% inclusive:
F= 100×( B−A ) 2 /B 2   (1)

(where A denotes an average wire diameter of the metal wires constituting the first metal wire group and the second metal wire group, and B denotes an average grid pitch of the first metal wire group and the second metal wire group).

4. The heat cooking device according to claim 1 , further comprising:
an openable-closable door that opens and closes the cooking chamber; and
a food-placement-section driver that moves the food placement section so as to draw the food placement section out from the cooking chamber in accordance with an opening operation of the openable-closable door and to return the food placement section into the cooking chamber in accordance with a closing operation of the openable-closable door.

5. A heat cooking device comprising:
a food placement section provided within a cooking chamber;
a lower heating member that is provided at a lower section within the cooking chamber and that heats food placed on the food placement section from below;
a steam generating unit that has a steam outlet in at least one sidewall of the cooking chamber and that blows steam between the food placement section and the lower heating member from the steam outlet; and
an openable-closable door that opens and closes the cooking chamber,
wherein an exhaust section that exhausts the steam is provided at an upper position between the openable-closable door and a front surface of the cooking chamber, and
wherein the exhaust section is a recess provided in at least one of an inner surface of the openable-closable door and the front surface of the cooking chamber.

6. The heat cooking device according to claim 5 , further comprising:
an operable section provided at a side of the openable-closable door on a front surface of the heat cooking device,
wherein the exhaust section is provided in an area located farther away from the operable section with reference to a center of the openable-closable door in a left-right direction as a boundary.
