Abstract

A top burner and a cooker having the top burner are provided. The top burner includes a first burner provided with a plurality of flame holes that form flame by combusting mixed gas and a second burner provided with a plurality of flame holes that form flame separated from the flame formed by the flame holes of the first burner by combusting the mixed gas. An arrangement of the flame holes of the first burner is realized in a different shape from an arrangement of the flame holes of the second burner.

Claims

1. A top burner comprising:

a first burner provided with a plurality of flame holes that form flame by combusting mixed gas; and

a second burner provided with a plurality of flame holes that form flame separated from the flame formed by the flame holes of the first burner by combusting the mixed gas,

wherein an arrangement of the flame holes of the first burner is realized in a different shape from an arrangement of the flame holes of the second burner.

2. The top burner according to claim 1, wherein the flame holes of one of the first and second burners are arranged in a close curve shape having long and short sides;

and

the flame holes of the other of the first and second burners are arranged in a circular shape having a diameter less than a length of the short side.

3. The top burner according to claim 1, wherein one of the first and second burners is located on a top surface of the other of the first and second burners.

4. The top burner according to claim 1, wherein the first burner comprises:

a first burner head formed in an oval or rectangular shape and having a second burner seating portion on which the second burner is disposed; and

a first burner cap provided on a top surface of the first burner head except for the second burner seating portion and forming the flame holes of the first burner together with the first burner head.

5. The top burner according to claim 1, wherein the second burner comprises:

a second burner head formed in a circular shape and disposed on the top surface of the first burner; and

a second cap provided on a top surface of the second burner head and forming the flame holes of the second burner together with the second burner head.

6. The top burner according to claim 1, further comprising a manipulation knob for controlling whether to supply of the mixed gas that will be combusted in the first and second burners and adjusting an amount of the mixed gas to the first and second burners.

7. The top burner according to claim 1, wherein the mixed gas is combusted in both the first and second burners or only in the second burner.

8. A top burner comprising:

an outer burner installed on a top surface of a top plate and provided at an edge thereof with a plurality of flame holes that form flame by combusting mixed gas; and

an inner burner installed on a top surface of the outer burner and provided at an edge located at an inside of the edge of the outer burner with a plurality of flame holes that form flame by combusting the mixed gas,

wherein a distance between one of the flame holes of the inner burner and one of the flame holes of the outer burner, which is closest to the one of the flame holes of the inner burner is different from a distance between another one of the flame holes of the inner burner and another one of the flame holes of the outer burner, which is closest to the another one of the flame holes of the inner burner.

9. The top burner according to claim 8, wherein the outer burner is formed in a polyhedron shape having an oval or rectangular cross-section;

and

the inner burner is formed in a polyhedron shape having a circular cross-section.

10. The top burner according to claim 8, wherein the outer burner is provided with an inner burner installing portion on which the inner burner is installed;

and

the mixed gas is supplied only into the outer burner except for the inner burner installing portion.

11. The top burner according to claim 8, wherein the outer burner comprises:

an outer burner head installed on a top surface of the top plate; and

an outer burner cap installed on a top surface of the outer burner head and forming the flame holes of the outer burner.

12. The top burner according to claim 11, wherein the outer burner head is provided with an inner burner installing portion on which the inner burner is installed;

and

the outer burner cap shields the top surface of the outer burner head except form the inner burner installing portion.

13. The top burner according to claim 11, wherein the flame holes of the outer burner are formed on edges of the outer burner head and outer burner cap except for the inner burner installing portion.

14. A cooker comprising:

a top plate defining an exterior of a top thereof;

a top grid that is provided on the top plate and on which an object to be heated is disposed;

the top burner according to claim 8, for heating the object disposed on the top grid;

a valve supplying mixed gas to the top burner; and

a manipulation knob controlling operation of a valve.

15. The cooker according to claim 14, wherein the manipulation knob controls the valve such that the mixed gas is supplied to only the inner burner or both the outer and inner burners.

16. The cooker according to claim 15, wherein the manipulation knob adjusts an amount of the mixed gas when the mixed gas is supplied only to the inner burner.

17. A cooker comprising:

a top plate defining an exterior of a top thereof;

a top grid that is provided on the top plate and on which an object to be heated is disposed;

the top burner according to claim 9, for heating the object disposed on the top grid;

a valve supplying mixed gas to the top burner; and

a manipulation knob controlling operation of a valve.

18. A cooker comprising:

a top plate defining an exterior of a top thereof;

a top grid that is provided on the top plate and on which an object to be heated is disposed;

the top burner according to claim 10, for heating the object disposed on the top grid;

a valve supplying mixed gas to the top burner; and

a manipulation knob controlling operation of a valve.

19. A cooker comprising:

a top plate defining an exterior of a top thereof;

a top grid that is provided on the top plate and on which an object to be heated is disposed;

the top burner according to claim 11, for heating the object disposed on the top grid;

a valve supplying mixed gas to the top burner; and

a manipulation knob controlling operation of a valve.

20. A cooker comprising:

a top plate defining an exterior of a top thereof;

a top grid that is provided on the top plate and on which an object to be heated is disposed;

the top burner according to claim 12, for heating the object disposed on the top grid;
