Cooking aparatus

1. A cooking apparatus comprising:

a cooking chamber having an opening;

a cabinet having the cooking chamber located therein, the cabinet including a blowing channel;

a blower generating a blowing force in the blowing channel;

a door configured to open and close the opening of the cooking chamber, the door having an air-gap to receive air discharged from the blowing channel and pollutants generated in the cooking chamber;

at least one pollutant discharge opening formed at the door to discharge at least a portion of the pollutants in the air-gap out of the door; and

a pollutant discharge member having at least one sloped surface sloped downwards towards the at least one pollutant discharge opening in an opening state of the door such that at least the portion of pollutants received in the air-gap are discharged to the at least one pollutant discharge opening by gravity when the door is opened.

2. The cooking apparatus of claim 1 , wherein the at least one pollutant discharge opening is located at least one of a left side and a right side of the door.

3. The cooking apparatus of claim 2 , wherein the at least one pollutant discharge opening includes a pollutant discharge opening located at each of the left side and the right side of the door, and

wherein the pollutant discharge member includes a left side part in communication with the pollutant discharge opening located at the left side of the door, and a right side part in communication with the pollutant discharge opening located at the right side of the door.

4. The cooking apparatus of claim 2 , wherein the door includes a front surface and a back surface spaced from the front surface, and the pollutant discharge member is spaced away from the back surface of the door.

5. The cooking apparatus of claim 2 , wherein the pollutant discharge member includes a groove extending along the at least one sloped surface to the at least one pollutant discharge opening.

6. The cooking apparatus of claim 1 , further comprising a barrier located under the pollutant discharge member so that the pollutants received in the air-gap are collected on the pollutant discharge member and the barrier, the barrier including a plate.

7. The cooking apparatus of claim 6 , wherein the barrier is located such that the flow in the air-gap is not interrupted by the barrier.

8. The cooking apparatus of claim 6 , wherein the barrier is formed of a thermal conductive material.

9. The cooking apparatus of claim 6 , wherein the door includes a door handle projected from the door in a direction away from the cooking chamber, and the barrier is correspondingly positioned at the door handle.

10. The cooking apparatus of claim 1 , wherein the air-gap of the door is in communication with the blowing channel when the door closes the opening of the cooking chamber.

11. The cooking apparatus of claim 10 , wherein the cabinet includes a cabinet outlet to allow the blowing channel to be in communication with the air-gap when the door closes the opening of the cooking chamber.

12. The cooking apparatus of claim 10 , wherein the door includes:

a first door panel; and

a second door panel positioned between the first door panel and the cooking chamber such that the air-gap is located between the second door panel and the first door panel, the second door panel includes an opening such that the air-gap is in communication with the blowing channel when the door closes the opening of the cooking chamber.

13. The cooking apparatus of claim 12 , wherein the pollutant discharge member is located in the air-gap opposite the opening in the second door panel.

14. A cooking apparatus comprising:

a cooking chamber having an opening;

a cabinet having the cooking chamber located therein, the cabinet including a blowing channel;

a door configured to open and close the opening of the cooking chamber, the door having a front surface, a back surface, and an air-gap to receive air discharged from the blowing channel and pollutants generated in the cooking chamber;

a hole formed at the door, the hole being in communication with the blowing channel when the door closes the opening of the cooking chamber; and

a pollutant discharge member having a sloped surface such that a portion of the pollutants in the air-gap are discharged into the cooking chamber through the hole of the door by gravity when the door closes the opening of the cooking chamber.

15. The cooking apparatus of claim 14 , further comprising:

an opening located in the back surface of the door, the opening being in communication with the air-gap.

16. The cooking apparatus of claim 15 , wherein the door includes at least one pollutant discharge opening located at least one of a left side and a right side of the door, and the pollutant discharge member includes a groove extending along the sloped surface to be connected to the at least one pollutant discharge opening.

17. The cooking apparatus of claim 14 , wherein a barrier is provided near the pollutant discharge member so that the pollutants in the door air-gap are collected on the pollutant discharge member and the barrier.

18. The cooking apparatus of claim 14 , wherein the door is hinge-coupled to the cabinet so that it is stood to be approximately vertical to up and down directions when the door is closed to be approximately horizontally disposed to up and down directions when the door is opened.
