Abstract:
1. An oven comprising: a cooking chamber in which food is cooked; a door to open or close a front side of the cooking chamber; a cooling fan located above the cooking chamber to suction and blow outside air; a discharge duct to discharge the air, blown by the cooling fan, forward of the door; a flow-path defined in the door to allow outside air to be introduced into and moved in the flow-path, in association with discharge of the air through the discharge duct; and a suction pipe connecting the flow-path and the cooling fan to each other to allow a part of the air moving in the flow-path to be suctioned toward the cooling fan, wherein the suction pipe includes a first suction pipe provided in the door and a second suction pipe to communicate the first suction pipe and the cooling fan with each other, wherein air is suctioned from the flow-path defined in the door, and then through the first suction pipe, and then through the second suction pipe, and then to the cooling fan, and wherein a part of the air moving in the flow-path defined in the door is suctioned through the first suction pipe and the second suction pipe and introduced into the cooling fan, and a remaining part of the air moving in the flow-path is discharged to an opening in the front of the door due to the Venturi effect produced by air discharged through the cooling fan, without flowing through the first suction pipe, the second suction pipe, and the cooling fan.
