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: A heating cooking appliance and a burner system thereof are provided. The height of the burner pot is reduced to facilitate product installation and reduce overall material and shipping costs. To increase user satisfaction with the product, a plurality of mixing tubes are extended in the same direction on one side of the burner pot in the burner system.

Abstract: A heating cooking appliance and a burner system of the same are provided. A nozzle and a mixing tube can be stably fixed, and relative position of components can be aligned with high precision even if the heating cooking appliance has a narrow internal space. Thus, operational reliability of the heating cooking appliance is improved, and an operator can easily assemble the burner system. To this end, a nozzle coupling part is configured to fix a position of a nozzle, and a mixing tube coupling part is configured to fix a position of the mixing unit. The nozzle coupling part and the mixing tube coupling part are partially coupled to achieve a precise relative positional relation between the nozzle and the mixing tube.

Abstract: The present invention relates to a top burner and a cooker including the top burner. The present invention includes: an outer burner installed on a top surface of a top plate, and provided with a plurality of flame holes to form flames through combusting gas mixture at a perimeter thereof; an inner burner installed on a top surface of the outer burner, and provided with a plurality of flame holes to form flames through combusting gas mixture at a perimeter thereof disposed inward to the perimeter of the outer burner; a plurality of first mixing tubes supplying gas mixture mixed with air inside the outer burner; a second mixing tube supplying gas mixture mixed with air inside the inner burner; and a passage formed through the outer tube, and in which air supplied to combust gas mixture at the flame holes of the inner burner flows. Thus, according to the present invention, the advantages of heating food more efficiently while reducing incomplete combustion of gas mixture can be realized.

Abstract: A gas cooker is provided. First and second front burners are disposed on the left and the right of a front upper surface of a top plate at an interval in a row. Lower ignition parts of the first and second front burners are disposed at a distance from an imaginary straight line passing through central points of the first and second front burners in parallel with the front end of the top plate, toward a front end of the top plate.

Abstract: Provided is a gas cooker. When foods are cooked using a top burner, inclinations of main flame holes defined in the top burner are different according to positions of the main flame holes to prevent textile disposed adjacent to a front end of a top plate from burning. Thus, a user may further safely cook the foods.

Abstract: A cooking device is provided. The cooking device includes a cavity and a burner. The cavity provides a cooking chamber. The burner is at the cooking chamber in the cavity and heats food in the cooking chamber. The burner includes a supply part and a combustion unit. A gaseous fuel mixed with air flows in the supply part. The combustion unit is connected to the supply part to receive the mixed gaseous fuel and to burn the received mixed gaseous fuel flowing within the combustion unit. The combustion unit has a single loop shape.

Abstract: A cooking device is provided. The cooking device includes a cavity and a burner. The cavity provides a cooking chamber. The burner is in the cavity and heats food in the cooking chamber. The burner includes a supply part and a combustion part. The supply part supplies a gaseous fuel mixed with air. The combustion part burns the mixed gaseous fuel and has an open curve shape.

Abstract: A heating cooking appliance is provided. The heating cooking appliance includes a case, a plate covering a top of the case, a burner system generating heat by combusting mixture gas in the case, a control unit controlling operation of the burner system, and a temperature increase preventing unit preventing a temperature of the control unit from increasing by the heat generated from the burner system. The temperature increase preventing unit is installed on the case.

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: An implementation of a heating cooker includes a case; a plate covering a top of the case; a plurality of burner systems provided in an internal space defined by the plate and the case; at least one switch controlling an on/off operation of the burner system; a temperature sensor detecting a temperature of the burner system and on-off-operated; and an alarming unit that generates an alarming signal according to at least one of on-operation of the switch and temperature value detected by the temperature sensor.

Abstract: A heating cooking appliance and a burner system of the same are provided. The heating cooking appliance includes a case, a plate that covers the case, a burner system under the plate, and an exhaust unit at a side of the plate. The burner system includes a burner pot providing a mixing space in which gas and air are uniformly mixed, a mixing tube through which the gas and air are supplied into the burner pot, and a nozzle maintained a predetermined distance from a mixing tube unit. A discharger of the nozzle is reduced in diameter. A discharging hole of the nozzle is formed to have a length/diameter ratio of 0.9 to 1.1. A venturi marking a boundary between a convergence and a divergence with respect to the diameter of the mixing tube is disposed at a middle part when the mixing tube is divided into three equal parts.

Abstract: A heating cooking appliance is provided. The heating cooking appliance includes a case, a plate, a burner system, and a warm zone guide. The plate covers the top of the case. The burner system is provided below the plate and defines a heating region on the plate. The heating region heats food. A warm zone guide defines a warm zone region on the plate through exposing at least a portion of an undersurface of the plate to combustion gas generated from the burner system during exhausting of the combustion gas.
