Abstract

A gas oven range may include a cavity forming a cooking chamber in which food may be cooked, and a burner assembly installed in the cavity. The burner assembly may include a burner having flame holes formed therein, and a cover covering the burner to form a burner chamber. The cover may include an inlet that guides air from the cooking chamber into the burner chamber and an outlet that discharges air heated by the burner. An air inlet may be formed at one wall of the cavity to introduce external air into the burner chamber.

First claim

What is claimed is:

1. A gas cooking apparatus, comprising:
a cavity that defines a cooking chamber; and
a burner assembly installed in the cavity, wherein the burner assembly includes:
a burner having a plurality of flame holes;
a plate that supports the burner;
a cover coupled in the cavity to cover the burner and define a burner chamber enclosing the burner, the cover having an inlet to guide air from the cooking chamber into the burner chamber and at least one outlet to discharge air heated by the burner; and
at least one air inlet formed at one wall of the cavity to introduce air from outside the cavity into the burner chamber, wherein the at least one air inlet includes:
a first air inlet, including an opening formed in a bottom wall of the cavity, at a position corresponding to a bottom end of the burner chamber; and
a second air inlet including:
an opening formed in a rear wall of the cavity; and
an air guide that extends between the opening in the rear wall of the cavity and a corresponding opening in the plate so as to guide external air into the burner chamber formed between the cover and the plate.

2. The apparatus of claim 1 , further including a partition provided in the burner chamber to partition the air flowing through the least one air inlet from the air heated by the burner in the burner chamber.

3. The apparatus of claim 2 , wherein the plate is provided between the cover and a corresponding peripheral wall of the cavity such that the burner chamber is defined by a space formed between the cover and the plate with the partition disposed between the cover and the plate.

4. The apparatus of claim 3 , wherein the partition extends between the cover and the plate so as to partition a space therebetween.

5. The apparatus of claim 2 , wherein the plate is provided between the cover and a corresponding peripheral wall of the cavity such that the burner chamber is defined by a space formed between the cover and the plate, having the first air inlet formed at the bottom wall of the cavity, at a portion of the bottom wall corresponding to a space formed between the cover and the plate.

6. The apparatus of claim 5 , wherein the plate contacts the bottom wall of the cavity.

7. The apparatus of claim 5 , further including a fan provided in a space formed between the plate and the peripheral wall of the cavity.

8. The apparatus of claim 7 , further including a fan motor that rotates the fan.

9. The apparatus of claim 1 , further including:
a recessed portion formed in the bottom wall of the cavity, wherein a lower end of the cover contacts the bottom wall of the cavity between the recessed portion and the at least one air inlet.

10. The apparatus of claim 1 , wherein the burner assembly is installed at a rear wall of the cavity in the cooking chamber.

11. The apparatus of claim 1 , further including a discharge port provided at a rear wall of the cavity through which burned gas is discharged out of the cavity.

12. The apparatus of claim 1 , wherein the burner includes a burner body and a supply pipe through which a mixture of gas and air is supplied to the burner body.

13. The apparatus of claim 12 , wherein the burner body is formed in a rounded shape to increase a flame generation area.

14. The apparatus of claim 13 , wherein the burner body has a U shape.

15. The apparatus of claim 13 , wherein the burner body has a hollow cylindrical shape, and wherein the plurality of flame holes is formed on an outer peripheral surface of the burner body.

16. The apparatus of claim 15 , wherein the plurality of flame holes is formed on an outer side on the outer peripheral surface of the burner body.

17. The apparatus of claim 13 , wherein the supply pipe is connected to a lower portion of the burner body so that the mixture of gas and air supplied to the burner body is divided to flow into two opposite sides of the burner body to generate even flames throughout the burner body.

18. The apparatus of claim 12 , wherein the burner body includes a plurality of protrusions that penetrates into the plate to couple the burner with the plate.

19. The apparatus of claim 12 , wherein the supply pipe penetratingly extends through the rear wall of the cavity to a rear side of the rear wall of the cavity.

20. A gas cooking apparatus, comprising:
a cavity that defines a cooking chamber;
a burner installed in the cavity and including a plurality of flame holes;
a cover coupled in the cavity so as to cover the burner and define a burner chamber;
an inlet and an outlet formed in the cover, the inlet guiding air from the cooking chamber into the burner chamber and the outlet discharging air heated by the burner from the burner chamber into the cooking chamber;
at least one air inlet formed at a peripheral wall of the cavity to guide air from outside the cavity into the burner chamber; and
a plate on which the burner is installed, wherein the cover is coupled to a rear wall of the cavity, wherein the plate having the burner coupled thereto is positioned in a space formed between the cover and the rear wall of the cavity, wherein a space formed between the plate and the cover defines the burner chamber together with a corresponding portion of a bottom wall of the cavity, wherein a space formed between the plate and the rear wall of the cavity defines an air passage in which a fan is installed, and wherein the at least one air inlet includes:
a first air inlet, including an opening formed in the bottom wall of the cavity, at a position corresponding to a bottom end of the burner chamber; and
a second air inlet including:
an opening formed in the rear wall of the cavity; and
an air guide that extends between the opening in the rear wall of the cavity and a corresponding opening in the plate so as to guide external air into the burner chamber formed between the cover and the plate.
