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

Patent number: 6674056Abstract: The apparatus for uniformly dispersing the microwave comprises a body including a plurality of reflective portions which are made of materials capable of reflecting the microwave and have the horizontal top surfaces and vertical side surfaces. The width of the plurality of reflective portions is set as 1/n times as large as a wavelength &lgr;g of the microwave. The depth of each of the plurality of reflective portions may be set as a value obtained by multiplying the remainder, which is obtained by dividing the power of a natural number for the least primitive root of a prime number by the prime number, by the width of the reflective portion under a condition that a datum plane is defined by a height from the bottom surface corresponding to a value obtained by multiplying the width of the reflective portion by (prime number−1).Type: GrantFiled: May 14, 2002Date of Patent: January 6, 2004Inventor: Young Hee Lee
