## 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.

## Claims

### Claim 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 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 rear end 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 accommodates the burner, the insulating case having an opened upper surface;
a first insulator inserted in a space defined between a perimeter of the insulating case and an outer side of the burner; and
an operation unit that is in contact with a lower surface of the plate and that is located between a front end of the plate and an outer side of the first insulator, the operation unit being configured to control of the gas cooker based on touch operation on an area of the plate corresponding with the operation unit,
wherein the plate is in contact with and presses the first insulator, and covers the opened upper surface of the insulating case and the burner.

### Claim 2 (depends on 1)

The gas cooker of claim 1, wherein the first insulator extends along a border of the insulating case.

### Claim 3 (depends on 2)

The gas cooker of claim 2, wherein an upper surface of the first insulator is in contact with the lower surface of the plate to cover the burner.

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 4)

The gas cooker of claim 4, wherein the first insulator comprises a sheet that is coupled to a circumferential portion of each burner.

### Claim 6 (depends on 4)

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.

### Claim 7 (depends on 6)

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.

### Claim 8 (depends on 1)

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

### Claim 9 (depends on 8)

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.

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 10)

The gas cooker of claim 10, wherein the burner includes:
a burner port configured to provide gas and hold the heating element,
a spark plug configured to ignite fire using the provided gas, wherein the heating element is heated by the ignited fire;
a burner holder that (i) is configured to hold the spark plug, (ii) is coupled between the burner port and the plate, and (iii) includes a burned gas guide portion that flows burned gas to the vent; and
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.

### Claim 12 (depends on 11)

The gas cooker of claim 11, wherein the second insulator is coupled to the burned gas guide portion.

### Claim 13 (depends on 12)

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.

### Claim 14 (depends on 9)

The gas cooker of claim 9, wherein the first insulator and the second insulator comprise compressible insulating material.

### Claim 15 (depends on 1)

The gas cooker of claim 1, wherein the first insulator comprises elastically deformable material that is configured to be compressed.

### Claim 16 (depends on 1)

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

### Claim 17 (depends on 16)

The gas cooker of claim 16, wherein the fan is configured to provide air flow to the insulating case.

### Claim 18 (depends on 1)

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

### Claim 19 (depends on 1)

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

### Claim 20 (depends on 1)

The gas cooker of claim 1, wherein the first insulator comprises a protrusion extended toward a bottom surface of the case and inserted into the space defined between the perimeter of the insulating case and the outer side of the burner.
