The present invention inhales outside air when the combustion material is burned to prevent soot produced by incomplete combustion or pyrolysis of the combustion material on the inner surface of the opening and closing door. The present invention relates to an air curtain device for a fireplace having a structure capable of spraying toward an open surface to form a predetermined air flow film on an inner surface of an open / close door.

In general, the fireplace is used as a heating device that burns firewood or other fuel to warm the room by the heat of combustion in addition to the purpose of the interior to further enhance the indoor atmosphere of a building or a house. Such a fireplace has a structure in which a combustion chamber is installed on a wall of a room and passes through a flue in the wall, and a brick is directly stacked on the wall to be separated from a wall as in a normal stove, thereby reducing heat loss through the wall. It is developing in the direction of reduction.

Therefore, when the solid fuel is put on the grill and ignited, the combustion gas generated while the solid fuel is burned is discharged through the flue, and the ash is collected in the ash tray through the grill.

However, in the conventional fireplace, black amorphous soot is generated by incomplete combustion or pyrolysis of solid fuel while solid fuel is combusted. Since it is made of a transparent material so that it can be released into the room, as time passes soot circulates the internal space of the combustion chamber soot is laminated on the inner surface of the opening and closing door to form a soot film having a predetermined thickness. Therefore, since the soot film is laminated on the surface of the opening and closing door, the user cannot directly check the appearance of the solid fuel burning, so the user opens the opening door at any time to check the combustion state of the solid fuel and whether the solid fuel is inserted. In addition to the hassle to be caused, there is a problem that the heat of combustion in the combustion chamber is blocked by the soot film and is not easily released into the room, resulting in a decrease in the heating efficiency of the room.

The present invention was conceived to improve the above problems, it is possible to suppress the soot caused by incomplete combustion or pyrolysis of the combustion material to be laminated on the inner surface of the opening door to maintain the inherent transparency of the opening and closing door in the combustion chamber Structure that can form a predetermined airflow film on the inner surface of the opening / closing door by sucking external air when the combustion material is burned so that the fuel can be easily released into the room, and spraying the outside air from the upper end of the crater to the open surface side of the crater.
