Abstract

The present invention relates to a gas oven. The gas oven includes: a cavity in which an oven chamber having an opened front surface is defined; a heating source installed in the cavity through the opened front surface of the oven chamber, the heating source providing energy for cooking foods in the oven chamber; a bracket fixing the heating source to the cavity; and a coupling member fixing the bracket to the cavity. The heating source is horizontally moved into the oven chamber when the heating source is fixed to the bracket, and is thus fixed to the cavity via the coupling member. Thus, a burner may be easily fixed and separated.

First claim

The invention claimed is:

1. A gas oven comprising:
an oven chamber having a top wall, a rear wall, a bottom wall, two side walls, a front wall that extends upward from a front end of the top wall, and an opening provided below the front wall;
a heating source installed in the oven chamber, the heating source providing energy to cook food in the oven chamber;
a bracket that fixes the heating source to the oven chamber, the bracket having a front attachment arm in contact with a front surface of the front wall at an outside of the oven chamber, a rear support arm in contact with the rear wall, and an upper attachment surface between the front attachment arm and the rear support arm and in contact with a lower surface of the top wall when the front attachment arm is in contact with the front surface of the front wall;
a first coupler that fixes the rear support arm to the oven chamber, wherein the first coupler includes a coupling hook that is positioned above a lower edge of the rear support arm and that extends from a rear surface of the rear support arm for insertion into a coupling slot defined in the rear wall; and
a second coupler that fixes the front attachment arm to the front wall,
wherein the second coupler passes into the front wall after passing through the front attachment arm, and
wherein when the second coupler is removed, the bracket pivots along the lower edge of the rear support arm to position the front attachment arm away from the front wall and to remove the coupling hook from the coupling slot such that the bracket can be separated from the oven chamber and withdrawn from the oven chamber through the opening.

2. The gas oven according to claim 1 , wherein the heating source provides radiant heat into the oven chamber.

3. The gas oven according to claim 2 , further comprising:
a temperature sensor to detect a temperature of the radiant burner; and
a valve to adjust a gas supplied into the radiant burner,
wherein the valve blocks supply of the gas into the radiant burner when the temperature of the radiant burner detected by the temperature sensor exceeds a preset safety temperature.

4. The gas oven according to claim 1 , wherein the heating source includes:
a burner pot to receive a mixed gas that is mixed with air, the burner pot having a passage in which the mixed gas flows;
a combustion mat installed on the burner pot to burn the mixed gas supplied into the burner pot on a bottom surface thereof;
a mixing tube to supply the mixed gas that is mixed with the air into the burner pot;
an ignition device to ignite the mixed gas burned on the combustion mat; and
a nozzle to generate the mixed gas supplied into the burner pot.

5. The gas oven according to claim 4 , wherein the passage has a flow-sectional area that is gradually decreased from an upstream side toward a downstream side in a flow direction of the mixed gas.

6. The gas oven according to claim 4 , wherein a plurality of flow interference ribs respectively having different distances spaced from the combustion mat to decrease a flow-sectional area from an upstream side to a downstream of the passage are provided inside the burner pot.

7. The gas oven according to claim 6 , wherein the flow interference ribs extend toward the combustion mat from one surface of the burner pot so that the distances spaced from the combustion mat are increased in stages from the upstream side toward the downstream side of the passage.

8. A gas oven comprising:
a cavity for providing an oven chamber, the cavity defined by a top wall, a rear wall, a bottom wall, two side walls, and a front wall that extends upward from an end of the top wall and provides an opening for the oven chamber;
a radiant burner horizontally moved into the oven chamber, the radiant burner being fixed to the cavity so that the radiant is provided in an upper portion of the oven chamber;
a burner bracket to which the radiant burner is fixed;
a first coupler that aligns the burner bracket at the rear wall of the cavity, wherein the first coupler includes a coupling hook that is positioned above a lower edge of a rear surface of the burner bracket and that extends from the rear surface of the burner bracket for insertion into a coupling slot; and
a second coupler that fixes a portion of the burner bracket to the front wall of the cavity, wherein the portion of the burner bracket is provided outside the oven chamber and in front of the front wall of the cavity when the radiant burner is provided within the oven chamber,
wherein the second coupler passes into the front wall of the cavity after passing through the portion of the burner bracket,
wherein the burner bracket includes an upper attachment surface in contact with a lower surface of the top wall when the second coupler passes through the front wall of the cavity, and
wherein when the second coupler is removed, the burner bracket pivots along the lower edge of the rear surface of the burner bracket to position the upper attachment surface away from the top wall and to remove the coupling hook from the coupling slot such that the bracket can be separated from the oven chamber and withdrawn from the oven chamber through the opening.

9. The gas oven according to claim 8 , wherein the burner bracket includes:
a burner support surface to which the radiant burner is fixed;
a front attachment arm attached to the front wall of the cavity by the second coupler; and
a rear support arm attached to the rear wall of the cavity by the first coupler.

10. The gas oven according to claim 9 , wherein the burner support surface, the front attachment arm, and the rear support arm are integrated with each other.

11. The gas oven according to claim 9 , wherein the rear support arm is temporarily fixed to the rear wall of the cavity by the first coupler.

12. The gas oven according to claim 8 , wherein the coupling slot is defined in the rear wall of the cavity.

13. The gas oven according to claim 8 , wherein the radiant burner includes:
a burner pot having a passage in which a mixed gas for radiant heating food within the oven chamber flows;
a combustion mat on which the mixed gas flowing into the passage is burned; and
at least one flow interference rib to interfere with a flow of the mixed gas supplied into the burner pot so that the mixed gas uniformly flows on an entire surface of the combustion mat.

14. The gas oven according to claim 13 , wherein the flow interference rib is longitudinally provided in plurality in a direction perpendicular to a flow direction of the mixed gas into the burner pot.

15. The gas oven according to claim 13 , wherein the at least one flow interference rib extends toward the combustion mat from one surface of the burner pot, and distances between front ends of the flow interference ribs and a top surface of the combustion mat are gradually decreased from an upstream side to a downstream side of the passage in a flow direction of the mixed gas flowing into the passage.

16. The gas oven according to claim 13 , wherein the flow interference ribs are spaced apart from each other in a flow direction of the mixed gas into the burner port.
