A gas burner device, comprising:

• a burner;
• and
• an injector configured to supply gas to the burner to generate a flame, the injector being on one side of the burner,
• the flame being generated around the burner as the gas supplied by the injector burns and the flame includes:
• a first flame portion farthest from an installation surface on which the gas burner device is installed;
• a second flame portion;
• and
• a third flame portion closest to the installation surface so that the second flame portion is between the first flame portion and the third flame portion and the second flame portion transitions the first flame portion into the third flame portion,
• wherein the first flame portion and the second flame portion are unblocked from each other, and
• the third flame portion is blocked from the first flame portion and the second flame portion,
• wherein the burner comprises:
• a stack structure formed by a first spreader, a second spreader, and a third spreader that are sequentially stacked toward the installation surface,
• wherein:
• the third flame portion is around a position between the third spreader and the second spreader,
• the second flame portion is around a position between the second spreader and the first spreader, and
• the first flame portion is around an opposite side of the second spreader in the first spreader,
• wherein the first spreader comprises:
• a first spreader body;
• a first gas receiving space formed inside the first spreader body;
• and
• a plurality of first flame holes arranged along a circumference of the first spreader body,
• wherein the plurality of first flame holes are formed by penetrating through the first spreader body, such that the first gas receiving space and the first flame portion are unblocked from each other,
• wherein the first spreader further comprises:
• a gas branch hole formed by penetrating through the first spreader body such that the first gas receiving space and inside of the second spreader are unblocked from each other.
