Abstract

A burner includes a burner head to receive a mixed gas; and a burner cap to cover the burner head, wherein the burner head includes an outer wall having a plurality of first flame holes through which a flame is discharged, an inner wall located at an inside of the outer wall and having a plurality of second flame holes through which the flame is discharged, and a mixed gas chamber between the outer wall and the inner wall; the burner cap includes a distribution guide to guide a flow of the mixed gas so that the mixed gas flows along a circumferential direction of the mixed gas chamber, and a first portion of the mixed gas flowing along the distribution guide is distributed to the first flame holes, and a second portion of the mixed gas flowing along the distribution guide flows toward the second flame holes.

Claims

1. A burner comprising:

a burner head to receive a mixed gas; and

a burner cap to cover the burner head,

wherein the burner head comprises an outer wall having a plurality of first flame holes through which a flame is discharged, an inner wall located at an inside of the outer wall and having a plurality of second flame holes through which the flame is discharged, and a mixed gas chamber between the outer wall and the inner wall,

wherein the burner cap comprises a distribution guide to guide a flow of the mixed gas so that the mixed gas in the mixed gas chamber flows in a circumferential direction of the mixed gas chamber, and

wherein a first portion of the mixed gas flowing along the distribution guide is distributed to the plurality of first flame holes, and a second portion of the mixed gas flowing along the distribution guide flows toward the plurality of second flame holes.

2. The burner according to claim 1, wherein the distribution guide protrudes downward from a lower surface of the burner cap, and includes a guide lower surface, a first guide surface, and a second guide surface to connect the guide lower surface to the lower surface of the burner cap.

3. The burner according to claim 2, wherein each of the first guide surface and the second guide surface is inclined at a predetermined angle with respect to a vertical line perpendicular to the lower surface of the burner cap.

4. The burner according to claim 2, wherein the burner head further comprises a mixed gas supply pipe to supply the mixed gas to the mixed gas chamber, and

wherein a width of the guide lower surface is smaller than an inner diameter of the mixed gas supply pipe.

5. The burner according to claim 4, wherein a part of the guide lower surface, and a part of each of the first and the second guide surfaces are longitudinally overlapped with the mixed gas supply pipe.

6. The burner according to claim 2, wherein the burner head further comprises a plurality of mixed gas supply pipes to supply the mixed gas to the mixed gas chamber, and

wherein the guide lower surface is longitudinally overlapped with each of the plurality of mixed gas supply pipes.

7. The burner according to claim 1, wherein the distribution guide is curved, and includes a first end and a second end spaced apart from each other, and

wherein a circumferential length of the distribution guide is longer than a horizontal distance between the first and the second ends of the distribution guide.

8. The burner according to claim 7, wherein the burner head further comprises a flame spread passage to spread the flame, and

wherein the flame spread passage is between the first and the second ends of the distribution guide.

9. The burner according to claim 1, wherein the burner head further comprises a chamber forming wall which forms a flame staying chamber for containing the flame, and

wherein the distribution guide includes a groove for preventing interference with the chamber forming wall.

10. The burner according to claim 1, wherein the distribution guide comprises a first distribution guide and a second distribution guide spaced apart from each other, and

wherein each of the first and the second distribution guides may be be convexly rounded in a direction away from a line bisecting the burner cap and passing between the first and the second distribution guides.

11. The burner according to claim 10, wherein the burner head further comprises a chamber forming wall which forms a flame staying chamber for containing the flame, and

wherein the chamber forming wall is between the first distribution guide and the second distribution guide.

12. The burner according to claim 10, wherein the burner head further comprises a flame spread passage to spread the flame, and

wherein the flame spread passage is between ends of the first and the second distribution guides.

13. The burner according to claim 10, wherein the burner head further comprises a first mixed gas supply pipe and a second mixed gas supply pipe to supply the mixed gas to the mixed gas chamber, and

wherein a part of the first distribution guide faces the first mixed gas supply pipe, and

wherein a part of the second distribution guide faces the second mixed gas supply pipe.
