DETAILS OF DOMESTIC STOVES OR RANGES, OF GENERAL APPLICATION - F23D: BURNERS ## Abstract A gas burner including a frame having an upper plate; a burner head seated on the upper plate and having a mixed gas flowing part; a burner cap seated on the burner head; and a burner body at which a nozzle configured to inject a gas to the burner head is installed, wherein the nozzle is disposed at an outside of the frame. ## Claims ### Claim 1 A gas burner comprising: a frame having an upper plate; a burner head provided on the upper plate, the burner head having a mixed gas flowing part and a mixed gas chamber in which a mixed gas is received; a burner cap provided on the burner head; and a burner body at which a nozzle to inject a gas to the burner head is provided, wherein the nozzle is disposed outside of the frame, wherein the mixed gas flowing part is provided at a lower surface of the burner head and extends radially from a center portion of the burner head, wherein the nozzle is spaced horizontally apart from the center portion of the burner head, wherein the nozzle is spaced horizontally apart from the mixed gas flowing part, such that the gas injected from the nozzle horizontally flows to the mixed gas flowing part, wherein the burner cap comprises a plurality of mixed gas discharging holes for generating a flame, wherein the burner head includes a guide part which guides the mixed gas flowing through the mixed gas flowing part upward, the guide part protrudes upward from a bottom wall forming the mixed gas chamber, and wherein the burner cap overlaps the bottom wall and the nozzle, and the bottom wall overlaps the nozzle in a vertical direction. ### Claim 2 (depends on 1) The gas burner of claim 1, wherein the burner body comprises: a nozzle installation part at which the nozzle is provided, wherein a portion of the burner body is provided within the frame, and wherein the nozzle installation part passes through an opening in the upper plate and is disposed outside of the frame. ### Claim 3 (depends on 2) The gas burner of claim 2, wherein a portion of the burner body blocks the opening. ### Claim 4 (depends on 1) The gas burner of claim 1, wherein the upper plate comprises at least one supporting part to support the burner head, and the burner head comprises at least one movement preventing part in contact with the at least one supporting part to prevent the burner head from moving in a horizontal direction. ### Claim 5 (depends on 4) The gas burner of claim 4, wherein the at least one supporting part protrudes upward from the upper plate and has a rounded surface. ### Claim 6 (depends on 4) The gas burner of claim 4, wherein the at least one movement preventing part protrudes downward from a lower surface of the burner head, and has at least two points of contact with each of the at least one supporting part. ### Claim 7 (depends on 4) The gas burner of claim 4, further comprising: a container supporting part provided on the upper plate to support a container. ### Claim 8 (depends on 1) The gas burner of claim 1, further comprising: an ignition part to ignite a mixed gas, wherein the burner cap includes a slit to spread the flame to one or more of the plurality of mixed gas discharging holes. ### Claim 9 (depends on 8) The gas burner of claim 8, wherein the burner head comprises a chamber forming wall to form a mixed gas chamber, the chamber forming wall having a mixed gas guide hole through which the mixed gas in the mixed gas chamber is discharged, and the mixed gas discharged from the mixed gas guide hole flows toward the ignition part. ### Claim 10 (depends on 8) The gas burner of claim 8, wherein the ignition part is provided at the burner body. ### Claim 11 (depends on 10) The gas burner of claim 10, wherein the upper plate of the frame comprises a hole through which the ignition part passes. ### Claim 12 (depends on 1) The gas burner of claim 1, further comprising: a flame detection part to detect whether the flame is generated at one or more of the plurality of mixed gas discharging holes, wherein the burner head comprises a recess in which at least a part of the flame detection part is received. ### Claim 13 (depends on 12) The gas burner of claim 12, wherein the flame detection part is provided at the burner body and passes through the upper plate. ### Claim 14 (depends on 12) The gas burner of claim 12, wherein a slit in which the flame stays is provided at the burner cap, and the slit is disposed between one or more of the plurality of mixed gas discharging holes and the flame detection part. ### Claim 15 A gas burner comprising: a frame having an upper plate; a burner head provided on the upper plate, the burner head having a mixed gas flowing part and a chamber forming wall configured to form a mixed gas chamber; a burner cap provided on the burner head and having a plurality of mixed gas discharging holes to generate a flame; and a burner body at which a nozzle to inject a gas to the burner head is provided; an ignition part configured to ignite a mixed gas; and a flame detection part configured to detect whether or not the flame is generated at one or more of the plurality of mixed gas discharging holes, wherein the burner head comprises a recess in which at least a part of the flame detection part is received, wherein the burner cap comprises a receiving recess in which at least a part of the flame detection part is located is provided at the edge of the burner cap and one or more slits provided at a position which is spaced from an inside of the receiving recess to allow the flame to be stayed therein. ### Claim 16 (depends on 15) The gas burner of claim 15, wherein the burner body comprises: a nozzle installation part at which the nozzle is provided, wherein a portion of the burner body is provided within the frame, and wherein the nozzle installation part passes through an opening in the upper plate and is disposed outside of the frame. ### Claim 17 (depends on 15) The gas burner of claim 15, wherein a portion of the burner body blocks the opening. ### Claim 18 (depends on 15) The gas burner of claim 15, wherein the upper plate comprises at least one supporting part to support the burner head, and the burner head comprises at least one movement preventing part in contact with the at least one supporting part to prevent the burner head from moving in a horizontal direction.
