Cooking Appliance

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.

1 . A cooker, comprising:
 a cavity including a cooking chamber; and   a burner disposed in the cavity, receiving a mixed gas mixed a gas and air, and generating a flame by burning the mixed gas,   wherein 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,   wherein the combustor includes a gap capable of shifting the flame by communicating between the plurality of flame holes.   
     
     
         2 . The cooker of  claim 1 , wherein the combustor includes an upper case and a lower case connected with the upper case, a flame hole forming portion for forming the plurality of flame holes is provided at one or more of the upper case and the lower case, and when the upper case and the lower case are connected, the upper case and the lower case are separated from each other at a space between plurality of flame holes. 
     
     
         3 . The cooker of  claim 2 , wherein a gap forming portion for forming the gap is formed at the upper case and the lower case. 
     
     
         4 . The cooker of  claim 1 , wherein the combustor is provided in plural and the supplier is connected with the plurality of combustors by a distributer. 
     
     
         5 . The cooker of  claim 1 , wherein a longitudinal length of the gap is smaller than that of the flame hole. 
     
     
         6 . The cooker of  claim 1 , wherein the combustors are disposed to be level with the inner part of the cavity. 
     
     
         7 . The cooker of  claim 1 , wherein an interval between ends of the adjacent flame holes is smaller than that of other portions. 
     
     
         8 . The cooker of  claim 7 , wherein each flame hole includes inside holes communicated with the inner space of the combustor and outside holes disposed at the outside of the inside holes and communicated with the cooking chamber, and a cross-sectional area of the channel of the outside holes is larger than that of the inside holes. 
     
     
         9 . The cooker of  claim 8 , wherein the cross-sectional area of the channel of the outside holes is increased as far away from the inside hole. 
     
     
         10 . A cooker, comprising:
 a cavity including a cooking chamber; and   a burner disposed in the cavity and including a supplier supplying a gas and an 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,   wherein the combustor includes an upper case and a lower case, flame hole forming portions for forming the plurality of flame holes are formed to be separated from each other at any one of the lower case and the upper case, two flame hole forming portions which are adjacent to each other are connected by a connecting portion, and when the upper case are connected to the lower case, the connecting portion is separated from a part of the other one of the upper case and the lower case facing the connecting portion.   
     
     
         11 . The cooker of  claim 1 , wherein the combustor is provided in plural, the supplier is connected with the plurality of combustors by a distributer, and some parts of the plurality of combustors are parallel to each other. 
     
     
         12 . The cooker of  claim 11 , wherein the plurality of combustors are disposed to be level with the inner part of the cavity. 
     
     
         13 . The cooker of  claim 10 , wherein a separate distance between the connecting portion and a part of the other one of the upper case and the lower case facing the connecting portion is smaller than the longitudinal length of the flame hole. 
     
     
         14 . The cooker of  claim 10 , wherein each flame hole includes inside holes communicated with the inner space of the combustor and outside holes disposed at the outside of the inside holes and communicated with the cooking chamber, and a cross-sectional area of the channel of the outside holes is larger than that of the inside holes. 
     
     
         15 . The cooker of  claim 14 , wherein the cross-sectional area of the channel of the outside holes is increased as far away from the inside holes.
