Patent number: 7629561Abstract: An electric oven with a hood is provided. An opening/closing member selectively opens and closes a hood exhaust passage to physically open or close a hood exhaust port. Thus, contaminated air detrimental to a hood fan can be prevented from being suctioned. Accordingly, a reduction in the suctioning force of the hood fan and contamination thereof can be prevented.Type: GrantFiled: December 26, 2007Date of Patent: December 8, 2009Assignee: LG Electronics Inc.Inventors: Sang Bum Sohn, Jong Sik Kim, Sung Bae Song

Publication number: 20090134155Abstract: A vent grille is provided. The vent grille is disposed on a front side of a microwave oven. Exhaust and inlet holes are disposed in a top side of the vent grille. The exhaust and inlet holes are not exposed when viewed from the front of the microwave oven. Air flows into and out of the microwave oven through the inlet and exhaust holes. An oblique guide surface or guide rib is provided to guide air discharged through the exhaust holes. Therefore, the frontal aesthetics of the microwave oven can be improved, and any safety hazard can be prevented. Furthermore, contaminants generated from food can be efficiently removed.Type: ApplicationFiled: October 24, 2008Publication date: May 28, 2009Inventors: Won Tae KIM, Jong Sik KIM, Sung Bae SONG
