Patent number: 9746187Abstract: An oven, which both satisfies heat insulating and cooling of a door by adjusting an air flow in channels formed in the door. The oven includes a plurality of channels provided in a door, into which external air flows, accompanied with air discharged by a discharge duct, such that the air flows in the plurality of the channels, and a flow conversion part formed above at least one of the plurality of the channels for stagnating the flow of air. Since the door insulates a cooking chamber from heat and is cooled using a difference of pressures between upper and lower portions of the door, the oven concurrently satisfies conflicting two requirements, such as heat insulating and cooling of the door.Type: GrantFiled: July 14, 2008Date of Patent: August 29, 2017Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Kyoung Ho Kim, Yun Ic Hwang, Seok Weon Hong, Jong Hak Hyun, Cheol Jin Kim, Yu Jeub Ha, Min Serk Kim, Kil Young Lee, Eun Oh Kim, Jin Hee Cho, Chan Park

Patent number: 9022017Abstract: An oven having enhanced cooling efficiency. The oven includes a cooking chamber, 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 plurality of flow-paths 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 to connect at least one of the flow-paths and the cooling fan to each other. Suction force of the cooling fan is applied to the flow-paths of the door through the suction pipe as well as the interior of an electric machine room, allowing the air in the flow-path to be discharged to the outside through the suction pipe and the discharge duct. This assures more active air movement in the door and maximizes the cooling effect of the door.Type: GrantFiled: February 24, 2011Date of Patent: May 5, 2015Assignee: Samsung Electronics Co., Ltd.Inventors: Jong Hak Hyun, Jae Man Joo, Jong Chull Shon, Ki Suk Jeon, Myoung Keun Kwon, Tae Woo Kim

Patent number: 6686574Abstract: A microwave oven includes two doors which primarily and secondarily prevent a leakage of microwaves from a cooking cavity during a cooking operation. A first door is rotatably hinged to a front wall of a cabinet of the microwave oven, so as to open and close an opening of the cooking cavity and primarily prevent the leakage of the microwaves from the cooking cavity. A second door is rotatably mounted to the cabinet in front of the first door to cover and uncover the front of the first door. The second door thus secondarily intercepts the microwaves which have leaked from the cooking cavity through a gap between the first door and the cabinet. The microwave oven effectively prevents almost all leakage of the microwaves from the cooking cavity during the cooking operation.Type: GrantFiled: October 28, 2002Date of Patent: February 3, 2004Assignee: Samsung Electronics Co., Ltd.Inventor: Jong-Hak Hyun
