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: 7686009Abstract: Disclosed herein is an oven that is capable of discharging hot air generated when cooling a door and heat generated in a cooking chamber through the lower end of the door. The oven includes a door having at least two separated air channels. The air channels comprise at least one first air channel to discharge hot air generated when cooling the door through the lower end of the door, and at least one second air channel to introduce air through the lower end of the door such that the door is cooled. In the housing is mounted a circulating fan. Between the circulating fan and the air channels is connected a channel connecting unit. As the circulating fan is rotated, air flows along the second air channel to cool the door. Hot air generated when cooling the door is introduced into the first air channel through the channel connecting unit, and is then discharged out of the oven through the lower end of the door.Type: GrantFiled: December 9, 2005Date of Patent: March 30, 2010Assignee: Samsung Electronics Co., LtdInventors: Sung Soo Park, Pung Yeun Cho, Cheol Jin Kim, Kyoung Ho Kim, Kil Young Lee, Sung Kwang Kim, Yu Jeub Ha, Yun Ic Hwang, Sang Hyun Kang, Seok Weon Hong, Tae Ho Kim
