Abstract

An oven with an enhanced structure to keep a cooking space clean includes a main body, a cooking chamber formed inside the main body and including a bottom wall, a burner provided at an outer lower part of the cooking chamber to heat up the cooking chamber, a door arranged to open or close the cooking chamber, a bottom plate coupled to the bottom wall of the cooking chamber with a gap from the bottom wall such that the bottom plate is located inside the cooking chamber, and an outlet for heated air formed between one end of the bottom plate facing the door and the bottom wall of the cooking chamber such that heated air generated from the burner is supplied to the door.

First claim

What is claimed is:

1. An oven comprising:
a main body;
a cooking chamber formed inside the main body and including a bottom wall;
a burner provided below the bottom wall of the cooking chamber and configured to generate heated air;
a door arranged to open or close the cooking chamber;
a bottom plate arranged above the bottom wall of the cooking chamber to cover the bottom wall of the cooking chamber and to be spaced apart from the bottom wall of the cooking chamber;
an outlet formed between an end of the bottom plate facing the door and the bottom wall of the cooking chamber, to discharge the heated air generated from the burner is toward the door;
a supporting plate coupled to the bottom wall of the cooking chamber, disposed between the bottom plate and the bottom wall, and including at least one moving hole formed at an end of the supporting plate facing the door to discharge the heated air therethrough and toward the outlet,
a guide bracket provided between the bottom plate and the supporting plate and disposed in an air path formed between the at least one moving hole and the outlet to guide the heated air discharged from the at least one moving hole to the outlet.

2. The oven of claim 1 , wherein the guide bracket is coupled to the supporting plate to cover the at least one moving hole.

3. The oven of claim 1 , wherein the guide bracket comprises
a first portion directed to the outlet and parallel to the bottom wall;
a second portion coupled to the supporting plate; and
a third portion connecting the first portion to the second portion and including a slope opposite the at least one moving hole.

4. The oven of claim 3 , wherein the first portion is located in a position higher than the second portion.

5. The oven of claim 3 , wherein the slope of the third portion includes an angle of approximately 30 degrees or greater and approximately 40 degrees or less relative to a horizontal line extending along a front to back direction of the cooking chamber to pass a point of contact between the second portion and the third portion.

6. The oven of claim 1 , wherein a distance between the end of the bottom plate facing the door and the bottom wall of the cooking chamber, which defines the outlet for heated air, is greater than or equal to approximately 6.9 mm and less than approximately 10 mm in a vertical direction of the cooking chamber.

7. The oven of claim 1 , wherein the at least one moving hole comprises a plurality of moving holes separately arranged along a left to right direction of the cooking chamber, each moving hole of the plurality of moving holes having long sides extending in the left to right direction of the cooking chamber and short sides extending in a front to back direction of the cooking chamber.

8. The oven of claim 1 , further comprising:
a plurality of main outlets formed to pass through the bottom plate such that the heated air generated from the burner is guided toward side walls of the cooking chamber through the plurality of main outlets.

9. The oven of claim 8 , wherein:
the bottom plate comprises
a bottom plate body in which the plurality of main outlets are formed; and
a border part formed along edges of the plurality of main outlets, and extending in a downward direction from the bottom plate body.

10. The oven of claim 9 , wherein the border part of the bottom plate comprises
a first border part extending downwardly from the perimeter of the plurality of main outlets; and
a second border part opposite from the first border part, extending downwardly from the perimeter of the plurality of main outlets, and the first border part extended longer than the second border part.

11. The oven of claim 10 , wherein the first border part includes an angle relative to a vertical line extending in a vertical direction of the cooking chamber.

12. The oven of claim 8 , further comprising:
a burner accommodation chamber disposed below the bottom wall of the cooking chamber and configured to accommodate the burner therein,
wherein the burner comprises
a first pipe arranged to be adjacent to a first side wall of the burner accommodation chamber;
a second pipe arranged to be adjacent to a second side wall of the burner accommodation chamber opposite to the first side wall; and
a third pipe arranged to be adjacent to the door and connecting the first pipe to the second pipe,
wherein each of the first pipe and second pipe has a plurality of first discharge holes formed thereon to discharge the heated air generated from the burner toward the side walls of the cooking chamber through the plurality of main outlets, and
wherein the third pipe has a plurality of second discharge holes formed thereon to discharge the heated air generated from the burner toward the door through the outlet.

13. The oven of claim 12 , wherein the plurality of second discharge holes are smaller in size than the plurality of first discharge holes.

14. The oven of claim 1 , wherein the support plate further includes a plurality of protrusions extended in a downward direction from the support plate and the at least one moving hole is formed between the plurality of protrusions.

15. An oven comprising:
a main body;
a cooking chamber formed inside the main body and including a bottom wall;
a door arranged to open or close the cooking chamber;
a burner provided below the bottom wall of the cooking chamber and configured to generate heated air, and including a pipe facing the door;
a bottom plate arranged above the bottom wall of the cooking chamber to cover the bottom wall of the cooking chamber and to be spaced apart from the bottom wall of the cooking chamber;
a heated air path arranged for the heated air generated from the burner to be discharged toward the door therethrough;
an outlet formed between a front end of the bottom plate and a front end of the bottom wall of the cooking chamber to discharge the air from the burner toward the door, and located in the heated air path;
a supporting plate coupled to the bottom wall of the cooking chamber, disposed between the bottom plate and the bottom wall, and including at least one moving hole located in the heated air path, and formed at an end of the supporting plate facing the door to discharge the heated air therethrough and toward the outlet; and
a guide bracket provided between the bottom plate and the supporting plate and disposed in the heated air path formed between the at least one moving hole and the outlet to guide the heated air discharged from the at least one moving hole to the outlet.

16. The oven of claim 15 , wherein the guide bracket comprises
a first portion directed to the front of the cooking chamber and parallel to the bottom wall;
a second portion directed to a back of the cooking chamber and coupled to the supporting plate; and
a third portion connecting the first portion to the second portion and including a slope opposite the at least one moving hole.
