Abstract

Disclosed is an oven having a sensor for sensing the air inside a cooking chamber so as to enable the cooked state of food materials to be recognized. The disclosed oven comprises: the cooking chamber; a first passage part disposed outside the cooking chamber so as to communicate with the cooking chamber; the sensor disposed inside the first passage part; a second passage part isolated from the first passage part, and through which forcibly suctioned external air is transferred; and an inlet and an outlet, which allow the first and second passage parts to communicate with each other, wherein, when the inlet is closed, the air inside the cooking chamber flows into the first passage part, and then passes through the sensor so as to be discharged through the outlet, and when the inlet is opened, the air flowing from the second passage part to the first passage part through the inlet passes through the sensor together with the air flowing into the first passage part from the inside of the cooking chamber so as to be discharged through the outlet.

First claim

What is claimed is:

1. An oven, comprising:
a cooking chamber;
a first passage part arranged outside the cooking chamber and coupled to receive air discharged from an outlet of the cooking chamber;
a sensor arranged in the first passage part; and
a second passage part separated from the first passage part by a partition, and through which forcibly suctioned external air is transferred;
the partition having an inlet and an outlet configured to selectively couple the first and second passage parts, such that based on the inlet being closed, air in the cooking chamber flows into the first passage part, and then passes the sensor to be discharged through the outlet of the partition, and based on the inlet being opened, air flowing from the second passage part into the first passage part through the inlet passes the sensor to be discharged through the outlet of the partition together with the air from the cooking chamber which flows into the first passage part from the outlet of the cooking chamber.

2. The oven as claimed in claim 1 , wherein the second passage part has a portion adjacent to the outlet of the partition that is narrower than a portion adjacent to the inlet of the partition.

3. The oven as claimed in claim 1 , wherein a cross-section of the second passage part gradually decreases from the inlet of the partition towards the outlet.

4. The oven as claimed in claim 1 , wherein the inlet of the partition comprises a main inlet into which external air is forcibly suctioned, and the outlet of the partition comprises a main outlet through which air transferred from the first and second passage parts is discharged.

5. The oven as claimed in claim 4 , wherein the main inlet is mounted with a blowing fan.

6. The oven as claimed in claim 1 , wherein the sensor is disposed downstream of the cooking chamber outlet which discharges air from the cooking chamber or the inlet of the partition on an air flow path along the first passage part.

7. The oven as claimed in claim 6 , wherein the outlet of the partition is disposed downstream of the sensor on the air flow path along the first passage part.

8. The oven as claimed in claim 1 , further comprising:
an opening and closing member configured to open and close the inlet of the partition; and
an actuator configured to drive the opening and closing member.

9. The oven as claimed in claim 8 , wherein an area of the inlet of the partition is smaller than an area of the outlet of the partition.

10. The oven as claimed in claim 1 , wherein the sensor is movably disposed to one of the first and second passage parts.

11. The oven as claimed in claim 10 , wherein the sensor is configured to open and close the inlet of the partition.

12. The oven as claimed in claim 1 , wherein the first passage part is formed between a first duct and the partition, and
wherein the second passage part is formed between a second duct and the partition.

13. The oven as claimed in claim 12 , wherein the partition is such that a portion including the inlet of the partition is inclined downwardly to one side.

14. An oven, comprising:
a cooking chamber;
a first duct arranged outside the cooking chamber and coupled to an outlet of the cooking chamber;
a sensor arranged in the first duct;
a partition coupled to the first duct, the partition including an inlet into which external air flows, and an outlet which discharges air in the first duct; and
a second duct coupled to the partition, the second duct including a main inlet into which external air is forcibly suctioned, and a main outlet which discharges internal air,
wherein air in the cooking chamber flows into the outlet of the cooking chamber, into the first duct, and passes the sensor to be discharged through the outlet of the partition in a cooking mode, and passes the sensor to be discharged through the outlet of the partition together with air flowing into the first duct from the second duct through the inlet in a cleaning mode.

15. The oven as claimed in claim 14 , wherein the sensor is disposed in a space through which air from the outlet of the cooking chamber and air flowing from the inlet of the partition flow together.

16. An oven, comprising:
a cooking chamber;
a first passage part arranged outside the cooking chamber and tunneled with the cooking chamber;
a second passage part separated from the first passage part, and through which forcibly suctioned external air is transferred;
a sensor movably disposed to one of the first and second passage parts; and
an inlet and an outlet configured to allow the first and second passage parts to be tunneled with each other,
wherein based on the inlet being closed, air in the cooking chamber flows into the first passage part, and then passes through the sensor to be discharged through the outlet, and based on the inlet being opened, air flowing from the second passage part into the first passage part through the inlet passes through the sensor to be discharged through the outlet together with the air in the cooking chamber which flows into the first passage part.
