Abstract

The present invention relates to a cooker. In the present invention, the exhaust gas of the upper cooking chamber flows into the upper duct and discharged to the outside of the cooker and the exhaust gas of the lower cooking chamber sequentially flows into the lower duct, the upper duct and discharged to the outside of the cooker, and the exhaust gas of the upper and lower cooking chamber is discharged to the outside of the cooker alone or in a mixed state thereof. Therefore, in the present invention, the exhaust gas generated during cooking foods in the upper cooking chamber and the lower chamber may be discharged by a simpler configuration.

First claim

What is claimed is:

1. A cooker, comprising:
a main body including a first cavity having a first cooking chamber and an upper exhaust port and a second cavity disposed at a lower side of the first cavity and having a second cooking chamber;
a first heating source providing heat for cooking foods in the first cooking chamber;
a second heating source providing heat for cooking foods in the second cooking chamber and independently operated from the first heating source;
a first duct including an upper duct and a lower duct in which exhaust gas generated during cooking foods in the first cooking chamber flows, the first duct having a length extending in a horizontal direction, the lower duct having an upper intake port and a communication hole;
a second duct in which exhaust gas generated during cooking foods in the second cooking chamber flows, the second duct having a length extending in the horizontal direction, the second duct being disposed at a rear side of the lower duct and being in contact with the lower duct in a front and rear direction;
a coupling device to couple the communication hole of the lower duct to the second duct; and
a cylindrical connection member having a predetermined diameter,
wherein the exhaust gas of the second cooking chamber flows into the second duct and is transferred to the upper duct,
wherein the exhaust gas from the lower duct and the exhaust gas from the second duct are discharged to an outside of the main body after flowing through the upper duct,
wherein the upper intake port and the communication hole are formed at opposed surfaces of the lower duct,
wherein a first end of the cylindrical connection member communicates with the upper exhaust port of the first cavity and a second end of the cylindrical connection member communicates with the upper intake port of the lower duct, and
wherein the cylindrical connection member maintains an interval between the first cavity and the first duct.

2. The cooker of claim 1 , wherein the position where the exhaust gas of the second cooking chamber is transferred from the second duct to the first duct is higher than the position where the first duct receives the exhaust gas of the first cooking chamber.

3. The cooker of claim 2 , wherein the position where the exhaust gas of the second cooking chamber flowing into the first and second ducts to the outside of the main body is higher than the position where the first duct receives the exhaust gas of the second cooking chamber flowing the second duct, the position where the first duct receives the exhaust gas of the first cooking chamber, and the position where the second duct receives the exhaust gas of the second cooking chamber.

4. A cooker, comprising:
a main body including a first cavity having a first cooking chamber and an upper exhaust port and a second cavity disposed at a lower side of the first cavity and having a second cooking chamber;
a first heating source providing heat for cooking foods in the first cooking chamber;
a second heating source providing heat for cooking foods in the second cooking chamber and independently operated from the first heating source;
a first duct having an upper duct and a lower duct in which first exhaust gas generated during cooking foods in the first cooking chamber flows, the lower duct having an upper intake port and a communication hole;
a second duct having a passage in which second exhaust gas generated during cooking foods in the second cooking chamber flows, at least one portion of the lower duct overlapping the second duct in a front and rear direction;
a coupling device to couple the at least one portion of the communication hole of the lower duct to the second duct; and
a cylindrical connection member having a predetermined diameter,
wherein the exhaust gas from the lower duct and the exhaust gas from the second duct are discharged to an outside of the main body after flowing through the upper duct,
wherein the upper intake port and the communication hole are formed at opposed surfaces of the lower duct,
wherein a first end of the cylindrical connection member communicates with the upper exhaust port of the first cavity and a second end of the cylindrical connection member communicates with the upper intake port of the lower duct, and
wherein the cylindrical connection member maintains an interval between the first cavity and the first duct.

5. The cooker of claim 4 , wherein the lower duct is disposed between the first cavity and the second duct.

6. The cooker of claim 4 , wherein at least a portion of the second duct is disposed between the first cavity and the second cavity.
