Patent ID: 7671310

Claim:
A microwave range having a hood for removing contaminated air, the microwave range comprising: a chamber having an inner cavity configured to receive items to be heated; an electric component room containing electric components, the electric component room being located above an upper wall of the chamber; an outer case defining at least one passage between the chamber and the outer case through which contaminated air is received and discharged, and through which air for cooling the electric components flows, wherein receiving and discharging of the contaminated air is performed by a vent fan assembly provided on the upper wall of the chamber, and the vent fan assembly is located at a rear end of the upper wall of the chamber that is adjacent to the electric component room to introduce and exhaust contaminated air flowing through a couple of passages provided between both sides of the chamber and both sides of the outer case positioned over the upper wall and both sides of the chamber; a divider that divides the at least one passage into a plurality of passages including an air introduction passage for venting, through which contaminated air is introduced, the divider comprising: a top bracket extending from an edge of the upper wall of the chamber to an inner surface of a side of the outer case; and first and second air walls provided on the upper wall of the chamber and the top bracket, wherein the top bracket separates the air introduction passage for venting from the air introduction passage for cooling, wherein the first air wall separates the air introduction passage for venting from the air introduction passage for cooling, and separates the exhaust passage for venting from the air introduction passage for cooling, and wherein the second air wall separates the air introduction passage for venting from the exhaust passage for cooling, and separates the exhaust passage for venting from the exhaust passage for cooling; an exhaust passage for venting, through which the contaminated air is exhausted; an air introduction passage for cooling, through which air for cooling the electric components is introduced; and an exhaust passage for cooling, through which the air for cooling the electric components is exhausted.
