Abstract

A gas oven configured to use a single cooking cavity being divided into a plurality of individual cooking cavities by mounting a divider at the cooking space. The gas oven includes a forced air supplying device capable of forcedly supplying air to the individual cooking space at an upper portion of the cooking space, and a natural air discharging device capable of naturally discharging waste air of the individual cooking space at a lower portion of the cooking space, when each individual cooking space is shut off by the divider.

First claim

What is claimed is:

1. A gas oven, comprising:
a body;
a cooking cavity formed at an inside of the body and formed to be dividable by a divider detachably mounted at the cooking cavity into a first individual cooking cavity at an upper portion of the body and a second individual cooking cavity at a lower portion of the body;
a first burner provided at the first individual cooking cavity;
a second burner provided at the second individual cooking cavity;
a main air supplying passage configured to communicate the second individual cooking cavity with an outside of the body to supply air to the second individual cooking cavity;
a main air discharging passage configured to communicate the first individual cooking cavity with an outside of the body to discharge waste gas of the first individual cooking cavity;
a subsidiary air supplying device configured to supply air to the first individual cooking cavity when the divider is mounted at the cooking cavity or when the first burner and the second burner are simultaneously operated, and configured to forcedly supply air to the first individual cooking cavity when the first burner and the second burner are simultaneously operated; and
a subsidiary air discharging device configured to discharge waste air of the second individual cooking cavity when the divider is mounted at the cooking cavity,
wherein the subsidiary air supplying device comprises an air supplying fan configured to forcedly move air.

2. The gas oven of claim 1 , wherein the subsidiary air supplying device further comprises:
a subsidiary air supplying passage configured to communicate the first individual cooking cavity with an outside of the body; and
an air supplying damper to open/close the subsidiary air supplying passage.

3. The gas oven of claim 2 , further comprising:
an air supplying duct configured to form the subsidiary air supplying passage,
wherein the first burner comprises an inlet hole disposed at an inside the air supplying duct in a way that at least a portion of the air that flows at an inside of the air supplying duct is introduced to an inside of the first burner.

4. The gas oven of claim 3 , wherein the air supplying duct comprises an overflow hole provided in a way that a remaining portion of the air that flows at the inside of the air supplying duct escapes to an outside of the air supplying duct to flow to surround the first burner.

5. The gas oven of claim 2 , wherein when the divider is separated from the cooking cavity and one of the first burner and the second burner is operated, the subsidiary air supplying device shuts off the subsidiary air supplying passage.

6. The gas oven of claim 2 , wherein when a self cleaning of the gas oven is performed, the subsidiary air supplying device shuts off the subsidiary air supplying passage.

7. A gas oven, comprising:
a body;
a cooking cavity formed at an inside of the body and formed to be dividable by a divider detachably mounted at the cooking cavity into a first individual cooking cavity at an upper portion of the body and a second individual cooking cavity at a lower portion of the body;
a first burner provided at the first individual cooking cavity;
a second burner provided at the second individual cooking cavity;
a main air supplying passage configured to communicate the second individual cooking cavity with an outside of the body to supply air to the second individual cooking cavity;
a main air discharging passage configured to communicate the first individual cooking cavity with an outside of the body to discharge waste gas of the first individual cooking cavity;
a subsidiary air supplying device configured to supply air to the first individual cooking cavity when the divider is mounted at the cooking cavity or when the first burner and the second burner are simultaneously operated, and configured to forcedly supply air to the first individual cooking cavity when the first burner and the second burner are simultaneously operated; and
a subsidiary air discharging device configured to discharge waste air of the second individual cooking cavity when the divider is mounted at the cooking cavity,
wherein the subsidiary air discharging device comprises
a subsidiary air discharging passage configured to communicate the second individual cooking cavity with an outside the body; and
an air discharging damper to open/close the subsidiary air discharging passage.

8. The gas oven of claim 7 , wherein the subsidiary air discharging passage is separately provided from the main air discharging passage, or joins the main air discharging passage at one point of the main air discharging passage.

9. The gas oven of claim 7 , wherein when the divider is separated from the cooking cavity, the subsidiary air discharging device shuts off the subsidiary air discharging passage.

10. The gas oven of claim 7 , wherein when a self cleaning of the gas oven is being performed, the subsidiary air discharging device shuts off the subsidiary air discharging passage.

11. A gas oven, comprising:
a body;
a cooking cavity formed at an inside of the body and formed to be dividable by a divider detachably mounted at the cooking cavity into a first individual cooking cavity at an upper portion of the body and a second individual cooking cavity at a lower portion of the body;
a first burner provided at the first individual cooking cavity;
a second burner provided at the second individual cooking cavity;
a first air supplying passage configured to communicate the first individual cooking cavity with an outside of the body to supply air to the first individual cooking cavity;
a first air discharging passage configured to communicate the first individual cooking cavity with an outside of the body to discharge waste gas of the first individual cooking cavity;
a second air supplying passage configured to communicate the second individual cooking cavity with an outside of the body to supply air to the second individual cooking cavity;
a second air discharging passage configured to communicate the second individual cooking cavity with an outside of the body to discharge waste gas of the second individual cooking cavity;
an air supplying damper configured to open/close the first air supplying passage, depending on whether the divider is attached/detached;
an air supplying fan configured to forcedly move air at an outside the body to the first individual cooking cavity through the first air supplying passage, depending on whether the first burner and the second burner are simultaneously operated; and
an air discharging damper configured to open/close the second air discharging passage, depending on whether the divider is attached/detached,
wherein the gas oven has a first mode during which the divider is mounted and only the first burner is operated, a second mode during which the divider is mounted and only the second burner is operated, a third mode during which the divider is mounted and the first burner and the second burner are simultaneously operated, a fourth mode during which the divider is separated and only the first burner is operated, a fifth mode during which the divider is separated and only the second burner is operated, and a sixth mode during which the divider is separated and the first burner and the second burner are simultaneously operated.

12. The gas oven of claim 11 , wherein in the first mode, the air supplying damper is open so that air is supplied to the first individual cooking cavity.

13. The gas oven of claim 11 , wherein in the second mode, the air discharging damper is open so that waste air of the second individual cooking cavity is discharged.
