Abstract

Disclosed herein is a gas oven including a body, a cooking space formed in the body, an air supply flow channel configured to connect the cooking space with an outside of the body to supply air to the cooking space, and a distribution unit configured to distribute or bend the air supplied through the air supply flow channel to supply the air to the cooking space. Through the distribution unit, it is possible to smoothly supply a primary air for mixing with gas and to smoothly supply a secondary air to an inside of the cooking space.

First claim

What is claimed is:

1. A gas oven comprising:
a body;
a cooking space formed in the body;
a burner provided in the cooking space;
an inner wall configured to form the cooking space;
an air supply flow channel configured to connect the cooking space with an outside of the body to supply external air from the outside of the body to the cooking space; and
a distribution unit provided at an ejection portion of the air supply flow channel, the ejection portion of the air supply flow channel formed in the inner wall and the distribution unit formed within the cooking space on the inner wall and configured to distribute the external air supplied through the air supply flow channel,
wherein the distribution unit comprises:
a distribution guide portion configured to distribute the external air supplied through the air supply flow channel; and
a supply guide portion configured to guide the external air that passes through the distribution guide portion to be supplied to one of the cooking space and the burner,
wherein the supply guide portion is formed on the inner wall along a whole circumference of the distribution guide portion, so that the distribution unit is configured to bend a flow of the external air supplied through the air supply flow channel to supply the air to the cooking space along the inner wall.

2. The gas oven of claim 1 , wherein the external air supplied through the air supply flow channel passes through the distribution guide portion and is discharged outside the distribution unit through the supply guide portion.

3. The gas oven of claim 1 , wherein the distribution unit is disposed in an ejection direction of the ejection portion of the air supply flow channel so as to not expose the ejection portion to the cooking space.

4. The gas oven of claim 1 , wherein the distribution guide portion comprises:
a distribution portion configured to distribute the external air supplied through the air supply flow channel; and
a guide portion provided adjacent to the distribution portion and configured to guide the external air distributed from the distribution portion.

5. The gas oven of claim 4 ,
wherein the distribution portion is formed closer to the inner wall than the guide portion.

6. The gas oven of claim 4 , wherein the guide portion comprises a first guide portion disposed on one side of the distribution portion, is disposed closer to a bottom surface of the cooking space than the distribution portion, and is configured to form a first guide flow channel in a longitudinal direction parallel to the bottom surface of the cooking space.

7. The gas oven of claim 6 , wherein the guide portion further comprises a second guide portion disposed on another side of the distribution portion and configured to form a second guide flow channel to be connected with the supply guide portion.

8. The gas oven of claim 7 , wherein the supply guide portion comprises:
a supply portion provided on one side of the distribution guide portion and configured to eject air that is mixed with gas that flows into the burner; and
an overflow portion formed along at least a part of a circumference of the distribution guide portion and configured to eject air to the cooking space, and
wherein the overflow portion comprises:
a first overflow portion formed along at least part of a circumference of the first guide portion; and
a second overflow portion formed along at least part of a circumference of the second guide portion.

9. The gas oven of claim 1 , wherein an inner surface of the distribution guide portion is formed to be curved to reduce pneumatic resistance of the air that passes through an inside of the distribution guide portion.

10. The gas oven of claim 1 , wherein the supply guide portion comprises:
a supply portion provided on one side of the distribution guide portion and configured to eject air that is mixed with gas that flows into the burner; and
an overflow portion formed along part of a circumference of the distribution guide portion and configured to eject air to the cooking space.

11. The gas oven of claim 10 , wherein the supply portion is formed to extend from the distribution guide portion and to be spaced at certain intervals along a circumference of a head portion of the burner.

12. The gas oven of claim 10 , comprising an inner wall configured to form the cooking space therein,
wherein the overflow portion comprises an overflow gap formed to be spaced at a certain interval from the inner wall and is formed along the circumference of the distribution guide portion.

13. The gas oven of claim 12 , wherein the overflow portion further comprises an overflow rib formed along an outer edge of the overflow portion to be bent toward the inner wall.

14. The gas oven of claim 1 , wherein the cooking space comprises a first separate cooking space on top and a second separate cooking space on bottom, and is provided to be dividable into the first separate cooking space and the second separate cooking space by a divider,
wherein the burner comprises:
a first burner provided in the first separate cooking space; and
a second burner provided in the second separate cooking space,

wherein the air supply flow channel comprises:
a second air supply flow channel configured to connect the second separate cooking space with the outside of the body and to supply external air to the second separate cooking space; and
a first air supply flow channel configured to connect the first separate cooking space with the outside of the body to supply external air to the first separate cooking space, and

wherein the distribution unit is disposed at the ejection portion of the first air supply flow channel.

15. A gas oven comprising:
a body;
one cooking space dividable into a first separate cooking space on top and a second separate cooking space on bottom by a divider separably mounted in the one cooking space;
an inner wall configured to form the cooking space;
one door configured to open and close the cooking space;
a first burner provided in the first separate cooking space;
a second air supply flow channel configured to connect the second separate cooking space with an outside of the body to supply external air from the outside of the body to the second separate cooking space;
a first air supply flow channel configured to connect the first separate cooking space with the outside of the body to supply external air from the outside of the body to the first separate cooking space, and
a distribution unit provided at an ejection portion of the first air supply flow channel, the ejection portion of the first air supply flow channel formed in the inner wall and the distribution unit formed within the first separate cooking space on the inner wall and configured to distribute the external air supplied from the first air supply flow channel to an inside of the first separate cooking space,
the distribution unit comprising;
a distribution guide portion configured to distribute the external air supplied through the first air supply flow channel; and
a supply guide portion configured to guide the external air that passes through the distribution guide portion to supply the external air to one of the cooking space and the first burner,
wherein the supply guide portion is formed on the inner wall along a whole circumference of the distribution guide portion, so that the distribution unit is configured to bend a flow of the external air supplied through the first air supply flow channel to supply the external air to the cooking space along the inner wall.
