Method and apparatus for maintaining a temperature in a chamber of a cooking device

1. A cooking device comprising:

a partitioning member, installed in a cooking chamber, for partitioning the cooking chamber into a first cooking chamber and a second cooking chamber;

means for heating food to be placed in the cooking chamber; and

means for ventilating air in the first cooking chamber and the second cooking chamber, independently, wherein the ventilating means comprises:

an air intake pipe for communicating an air intake hole formed at a front side of the cooking device with the cooking chamber; and

a blower, installed at an intermediate portion of the air intake pipe, for ventilating the air in the cooking chamber by force.

2. The cooking device as set forth in claim 1 , wherein the air intake pipe is branched into a first branch pipe communicated with the first cooking chamber, and a second branch pipe communicated with the second cooking chamber, and

further comprising a valve, installed at a branched point of the air intake pipe, for selectively communicating the air intake hole with the first cooking chamber or the second cooking chamber.

3. A method for maintaining the temperature in a first cooking chamber of a cooking device including at least first and second cooking chambers, the method comprising:

supplying heat to first and second cooking chambers;

measuring the temperature in the first chamber;

comparing the temperature in the first cooking chamber to a first predetermined temperature;

ventilating air into the first cooking chamber until the temperature in the first cooking chamber equals the predetermined temperature; and

exhausting air in the first cooking chamber at a predetermined time interval.

4. A method for maintaining the temperature in a first cooking chamber of a cooking device including at least first and second cooking chambers, the method comprising:

supplying heat to first and second cooking chambers;

measuring the temperature in the first chamber;

comparing the temperature in the first cooking chamber to a first predetermined temperature;

ventilating air into the first cooking chamber until the temperature in the first cooking chamber equals the predetermined temperature;

measuring the temperature in the second cooking chamber;

comparing the temperature in the second cooking chamber to a second predetermined temperature;

ventilating air into the second cooking chamber until the temperature in the second cooking chamber equals the predetermined temperature; and

exhausting air in the first cooking chamber at a predetermined time interval, and exhausting air in the second cooking chamber at a different predetermined time interval.

5. A cooking device comprising:

a cooking chamber;

a partition, which is installed in a cooking chamber, and which divides the cooking chamber into a first cooking chamber and a second cooking chamber;

a first heating section supplying heat to the first cooking chamber, and a second heating section supplying heat to the second cooking chamber;

an intake supplying air outside of the cooking chamber to at least one of the first and second cooking chambers;

an exhaust which exhausts air from at least one of the first and second cooking chambers;

a first temperature sensor sensing the temperature in one of the first and second cooking chambers; and

a controller controlling the intake to at least one of the first and second cooking chambers based on a comparison of the temperature sensed by the first temperature sensor and a first predetermined temperature.

6. The cooking device as set forth in claim 5 , wherein the first temperature sensor is installed in the first cooking chamber, and further comprising a second temperature sensor, which is installed in the second cooking chamber.

7. The cooking device as set forth in claim 6 , wherein the controller controls the intake to the first cooking chamber based on the comparison of the temperature sensed by the first temperature sensor and a first predetermined temperature, and controls the intake to the second cooking chamber based on another comparison of the temperature sensed by the second temperature sensor and a second predetermined temperature.

8. The cooking device as set forth in claim 5 , wherein the controller exhausts air in at least one of the first cooking chamber and second cooking chamber at a predetermined time interval.

9. The cooking device as set forth in claim 7 , wherein the controller exhausts air in the first cooking chamber at a predetermined time interval, and exhausts air in the second cooking chamber at a different predetermined time interval.
