Abstract

A gas cooker that includes a case defining an interior area, the case including an opening to the interior area; a plate covering, fully or in part, the opening of the case; a burner that is located in the interior area of the case, wherein the burner includes a heating element that is heated using gas; a vent that is located at a first position of the case and that is configured to discharge burned gas from the interior area of the case to an exterior of the case; an insulating case that is coupled to the burner and that is configured to hold the burner; and a first insulator that is coupled between the insulating case and the plate and that is configured to seal an interior space of the burner is disclosed.

First claim

What is claimed is:

1. A gas cooker comprising:
a case defining an interior area, the case including an opening to the interior area;
a plate covering, fully or in part, the opening of the case;
a vent that is located at the case and that is configured to discharge burned gas from the interior area of the case to an exterior of the case;
a burner located in the interior area of the case, wherein the burner includes: a heating element heated using gas;
a burner port configured to provide gas and hold the heating element; and
a burner holder that is configured to hold the burner port and that includes a burned gas guide portion that flows burned gas to the vent;
an insulating case disposed inside of the case and accommodating the burner; and
a first insulator that is disposed between the insulating case and the plate and that is formed along a circumference of the insulating case and a circumference of the burner;
wherein an upper surface of the first insulator is in close contact with a lower surface of the plate and a space above the burner is partitioned by the first insulator to prevent heat of the burner from being transferred to an outer area of the burner.

2. The gas cooker of claim 1 , wherein a first end of the first insulator extends to the vent.

3. The gas cooker of claim 1 , wherein the first insulator is formed along an outer circumference of the burner holder.

4. The gas cooker of claim 1 , further comprising a plurality of burners located in the interior area of the insulating case,
wherein the first insulator covers areas between the plurality of burners.

5. The gas cooker of claim 1 , wherein the insulating case is extended to the vent and the insulating case has an exhaust port formed at a corresponding position to the vent to exhaust a cooling air of inside of the case.

6. The gas cooker of claim 4 , wherein the first insulator includes:
a border portion coupled to a circumferential portion of the insulating case; and
a partitioning portion that extends from a first area of the border portion to the vent,
wherein the partitioning portion, in part or fully, covers areas between the plurality of burners.

7. The gas cooker of claim 6 , wherein the partitioning portion includes one or more branches and is coupled to a circumferential portion of each burner.

8. The gas cooker of claim 1 , further comprising:
a second insulator that is disposed between the burner holder and the insulating case and that is configured to reduce heat transfer from an interior space of the burner to the insulating case.

9. The gas cooker of claim 8 , wherein the insulating case includes a burner hole that holds the burner, and
wherein the second insulator includes an open area corresponding to the burner hole and covers a surrounding area of the burner hole of the insulating case.

10. The gas cooker of claim 9 , wherein a border line of the open area substantially matches to a border line of the burner hole.

11. The gas cooker of claim 5 , wherein the burner further includes:
a spark plug mounted on the burner holder and configured to ignite fire using the provided gas, wherein the heating element is heated by the ignited fire;
a burner cover that is configured to cover the burned gas guide portion of the burner holder and that is configured to flow burned gas to the vent.

12. The gas cooker of claim 8 , wherein the second insulator is coupled to the burned gas guide portion.

13. The gas cooker of claim 12 , further comprising a plurality of burners located inside the insulating case,
wherein the second insulator is coupled to each of the plurality of burners and configured to reduce heat transfer from each of the plurality of burners to the insulating case.

14. The gas cooker of claim 8 , wherein the first insulator and the second insulator comprise compressible insulating material.

15. The gas cooker of claim 9 , further comprising:
a plate bracket that is coupled to the plate and that is configured to hold the first insulator to prevent the first insulator from contacting the case.

16. The gas cooker of claim 15 , wherein the first insulator or the second insulator comprises elastically deformable material that is configured to be compressed.

17. The gas cooker of claim 1 , further comprising:
a fan configured to provide air flow to the vent.

18. The gas cooker of claim 17 , wherein the fan is configured to provide air flow to the insulating case.

19. The gas cooker of claim 1 , wherein the plate is a metal plate.

20. The gas cooker of claim 1 , wherein the plate is a ceramic plate.

21. The gas cooker of claim 1 , wherein the insulating case comprises a border which extends upwardly along an outer circumference of the insulating case.

22. The gas cooker of claim 21 , wherein the first insulator is inserted in a space formed between an inner side of the insulating case and an outer side of the burner.
