Thus, according to the present invention, the advantages of heating food more efficiently while reducing incomplete combustion of gas mixture can be realized.

Abstract: The present invention relates to an oven range. In the present invention, the air heated by the burner is guided by the air duct and transferred into the oven chamber, and guided so as to flow evenly in the oven chamber by the air guide. Therefore, the cooking food can be more efficiently cooked.

Abstract: A top burner and a cooker having the top burner are provided. A flame transfer slit for guiding the flame formed by the combustion of the mixed gas at an outer burner to an inner burner. A shielding member is provided to shield the flame transfer slit. Therefore, the object to be heated is uniformly heated and the flame transfer from the outer burner to the inner burner can be effectively realized.

Abstract: Provided are a burner system and a heating and cooking appliance having the same. The burner system includes a burner pot, and a mixing tube unit. The burner pot provides a space where a gas and air mix and burn, and the mixing tube unit is integrally formed with the burner pot to guide the gas and the air to the burner pot. The burner pot and the mixing tube unit include a plurality of members coupled vertically and forming an appearance.

Abstract: Provided is a cooker. The cooker includes a cavity including a cooking chamber; and a burner disposed in the cavity, receiving a mixed gas of a gas and air, and generating a flame by burning the mixed gas, in which the burner includes a supplier supplying the gas and the air and at least one combustor receiving the gas and the air from the supplier and including a plurality of flame holes generating the flame, and the combustor includes a gap capable of shifting the flame by communicating between the plurality of flame holes.

Abstract: A gas oven range and a reflector are provided. The gas oven range comprises an oven chamber in which food is cooked and an upper burner inside the oven chamber. The reflector reflects flame and heat and divides the oven chamber into a combustion space and an exhaust space. An exhaust hole is formed in the reflector to discharge combustion gas to the exhaust space, which is generated by combustion of gas at the burner in the combustion space. Therefore, incomplete combustion of gas is prevented, and leakage of flame and radiant heat generated by combustion of gas is prevented, thereby improving gas combustion efficiency.

Abstract: Provided is a cooker. There is provided the cooker including: a cavity including a cooking chamber; and a burner disposed in the cavity, receiving a mixed gas of a gas and air, and generating a flame by burning the mixed gas, wherein the burner includes a supplier supplying the mixed gas of the gas and air and a combustor connected with the supplier, receiving the mixed gas from the supplier, and including a plurality of flame holes, and an interval between ends of adjacent flame holes is smaller than an the interval between other portions.

Abstract: Provided is a cooker including: a cavity including a cooking chamber; and a burner disposed in the cavity, receiving a mixed gas of a gas and air, and generating a flame by burning the mixed gas, in which the burner includes a first combustor having a plurality of flame holes and a second combustor connected with the first combustor and having a plurality of flame holes.

Abstract: The present invention provides an oven range. In the present invention, an inlet allowing air in a burner chamber heated by a burner to be guided into an oven chamber by an air duct is formed on the rear surface of the oven chamber. Accordingly, according to the preset invention, a bottom area of the oven chamber on which cooling food is seated can be maximized and contamination of the burner chamber can be minimized.

Abstract: A burner and a gas oven including the burner are provided. Food placed in an oven chamber is heated and cooked by using a burner disposed at an upper side of the oven chamber and having a fork or grating shape. Therefore, the food can be heated more uniformly.

Abstract: A top burner and a cooker having the top burner are provided. A flame transfer slit for guiding the flame formed by the combustion of the mixed gas at an outer burner to an inner burner. A shielding member is provided to shield the flame transfer slit. Therefore, the object to be heated is uniformly heated and the flame transfer from the outer burner to the inner burner can be effectively realized.
