Cooking Appliance

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.

1 . A cooker, comprising:
 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 first combustor having a plurality of flame holes and a second combustor connected with the first combustor and having a plurality of flame holes.   
     
     
         2 . The cooker of  claim 1 , wherein the second combustor includes a distributer to which the mixed gas flows from the first combustor and a plurality of branches branched from the distributer. 
     
     
         3 . The cooker of  claim 2 , wherein ends of the plurality of branches are spaced apart from each other. 
     
     
         4 . The cooker of  claim 2 , wherein the ends of the plurality of branches are connected to each other. 
     
     
         5 . The cooker of  claim 1 , wherein the first combustor has a linear shape. 
     
     
         6 . The cooker of  claim 1 , wherein the second combustor includes a curved portion rounded at a predetermined curvature, the curved portion includes an outer portion having a plurality of flame holes and an inner portion having a plurality of flame holes, and an interval between the flame holes of the inner portion is larger than an interval between the flame holes of the outer portion. 
     
     
         7 . The cooker of  claim 6 , wherein the curved portion further includes a linear portion having a plurality of flame holes and an interval between the flame holes of the inner portion is larger than an interval between the flame holes of the linear portion. 
     
     
         8 . The cooker of  claim 1 , wherein the second combustor includes a linear portion and the first combustor is connected to the linear portion. 
     
     
         9 . The cooker of  claim 1 , wherein the first combustor is positioned on a lateral bisecting line of the ceiling surface of the cooking chamber. 
     
     
         10 . The cooker of  claim 1 , wherein the second combustor has a bilateral symmetry based on the first combustor. 
     
     
         11 . A cooker, comprising:
 a cavity including a cooking chamber; and   a burner disposed in the cavity, receiving a mixed gas of a gas and an air, and generating a flame by burning the mixed gas,   wherein the burner includes a first combustor generating the flame and a second combustor connected with the first combustor and receiving the mixed gas from the first combustor, and the second combustor is formed in a closed curve shape.   
     
     
         12 . The cooker of  claim 11 , wherein the second combustor includes a distributer receiving the mixed gas from the first combustor and the mixed gas flowing into the distributer is branched and flowed. 
     
     
         13 . The cooker of  claim 11 , wherein the second combustor includes an outer portion having a plurality of flame holes and an inner portion having a plurality of flame holes, and an interval between the flame holes of at least a part of the inner portion is larger than an interval between the flame holes of the outer portion. 
     
     
         14 . A cooker, comprising:
 a cavity including a cooking chamber; and   a burner disposed in the cavity, receiving a mixed gas of a gas and an air, and generating a flame by burning the mixed gas,   wherein the burner includes a first combustor generating the flame and a second combustor connected with the first combustor and receiving the mixed gas from the first combustor, and the second combustor is formed in an open curve shape in which a part thereof is opened.   
     
     
         15 . The cooker of  claim 14 , wherein the first combustor is formed in a linear shape and extends horizontally from the second combustor. 
     
     
         16 . The cooker of  claim 14 , wherein the second combustor includes a distributer receiving the mixed gas from the first combustor and the mixed gas flowing into the distributer is branched and flowed. 
     
     
         17 . The cooker of  claim 14 , wherein the second combustor includes an outer portion having a plurality of flame holes and an inner portion having a plurality of flame holes, and an interval between the flame holes of at least a part of the inner portion is larger than an interval between the flame holes of the outer portion.
