Abstract

A cooking device comprises a frame including supporting parts to support a tray on which food is put; a partitioning plate to divide an inner space of the frame into a cooking chamber and an air flow chamber; a burner in the air flow chamber; and a fan in the air flow chamber, wherein the partitioning plate includes an air inlet to introduce air inside the cooking chamber into the air flow chamber, and air outlets to discharge air heated by the burner in the air flow chamber to the cooking chamber, and the air outlets include a first air outlet and a second air outlet located at a lower level than the first air outlet, at least a part of the second air outlet is located at a lower level than the tray while the tray is supported by a lowermost supporting part of the supporting parts.

First claim

What is claimed is:

1. A cooking device comprising:
a frame including a plurality of supporting parts to support a tray on which food is put, the plurality of supporting parts being vertically separated from each other;
a partitioning plate configured to divide an inner space of the frame into a cooking chamber and an air flow chamber in the frame;
a burner disposed in the air flow chamber; and
a fan disposed in the air flow chamber,
wherein the partitioning plate includes:
a front plate;
an extension part configured to extend from the front plate toward a rear wall of the frame;
an air inlet configured to introduce air in the cooking chamber into the air flow chamber and provided in the front plate; and
a plurality of air outlets configured to discharge air heated by the burner disposed in the air flow chamber to the cooking chamber, wherein the plurality of air outlets are provided in the extension part and an uppermost height of each of the plurality of air outlets is located at or below an uppermost height of the air inlet, and
the plurality of air outlets include:
a first air outlet having a first singular unique opening; and
a second air outlet located at a lower level than the first air outlet and having a second singular unique opening,
wherein at least a part of the first air outlet is located above the tray while the tray is supported by a lowermost supporting part of the supporting parts,
wherein at least a part of the second air outlet is located at a lower level than the tray while the tray is supported by the lowermost supporting part of the supporting parts,
wherein a width of the second singular unique opening is greater than a width of the first singular unique opening, and
wherein a vertical length of the first singular unique opening is greater than a vertical length of the second singular unique opening.

2. The cooking device of claim 1 , wherein the at least a part of the second air outlet is located at a lower level than the lowermost supporting part of the supporting parts.

3. The cooking device of claim 1 , wherein at least a part of the first air outlet is located at a higher level than the tray while the tray is supported by the lowermost supporting part of the supporting parts.

4. The cooking device of claim 1 , wherein the at least a part of the second air outlet is located at a lower level than the air inlet.

5. The cooking device of claim 4 , wherein the entire second air outlet is located at a lower level than the air inlet.

6. The cooking device of claim 1 , wherein a highest point of the first air outlet is located at a lower level than a highest point of the air inlet.

7. The cooking device of claim 1 , further comprising a third air outlet provided in the extension part and horizontally separated from the first air outlet, the third air outlet having a third singular unique opening.

8. The cooking device of claim 7 , further comprising a flow guide which guides a flow of air discharged from one or more of the first air outlet and the third air outlet.

9. The cooking device of claim 8 , wherein the flow guide includes:
a guide part configured to obliquely extend from the extension part toward a front side of the cooking chamber; and
connecting parts configured to connect an upper end and a lower end of the guide part to the extension part.
