Abstract: Provided is a cooking apparatus including a first heating unit that has a first hole and generates heat using a first heat source, a second heating unit that is arranged to be stacked on the first heating unit, has a second hole formed at a position corresponding to the first hole, and generates heat using a second heat source, and a temperature detection unit that is arranged to protrude to the outside of the second hole while being arranged in the first hole of the first heating unit and the second hole of the second heating unit, and detects a temperature of a cooking vessel when the cooking vessel is brought into contact with the temperature detection unit. The output of each of the first heating unit and the second heating unit is controlled at levels of multiple stages by detecting a temperature of a lower portion of the cooking vessel, and food is cooked at an optimum temperature, thereby improving the taste of the food resulting in improved user satisfaction.

Abstract: A gas burner apparatus and a cooking apparatus including the same are provided. The gas burner apparatus a first burner, a second burner spaced apart from a lower side of the first burner, a support plate on which the second burner is disposed, and a secondary air supply flow channel to supply secondary air to the first burner, the secondary air supply flow channel including a first secondary air supply flow path formed between the first and second burners and a second secondary air supply flow path starting from an area lower than the support plate, the first and second paths being connected to each other.

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.

Abstract: A gas oven having a gas supplying passage to supply gas to a burner is provided. The gas oven includes an ON/OFF valve to open/close the gas supplying passage, and a flow rate modulating valve connected to the ON/OFF valve in series so as to change the cross-sectional area of a passage, thereby supplying a proper amount of gas to a cooking cavity in response to the change of a cooking area. When a cooking cavity is divided into individual cooking cavities while a divider is mounted, the flow rate modulating valve is open/closed at a smaller opening degree than the maximum operating degree, and thus may be able to prevent a cooking substance from being carbonized in the individual cooking cavities.
