Patent number: 6765184Abstract: A smoke guiding apparatus of a wall-mounted microwave oven. A driving circuit of the smoke guiding apparatus includes limit switches which are turned on or off according to a moving position of a guide plate of the smoke guiding apparatus, a relay coil which is supplied with power in response to an exhaust motor of the microwave oven being operated, and a plurality of relay switches which are turned on or off by the supply of power to the relay coil. The driving circuit is implemented without using a conventional microcomputer. Accordingly, the entire manufacturing cost of the microwave oven is reduced. The instant smoke guiding apparatus can be applied to mechanical microwave ovens which are not provided with microcomputers. Furthermore, the driving circuit can drive a smoke guiding apparatus having an AC feed motor, as well as a DC feed motor, thus enabling the AC feed motor to be applied to the smoke guiding apparatus.Type: GrantFiled: December 9, 2002Date of Patent: July 20, 2004Assignee: Samsung Electronics Co., Ltd.Inventor: Ha-Yeong Yang

Patent number: 6720543Abstract: A wall-mounted type microwave oven includes a cleaning device which is in contact with a guide plate and cleans the guide plate during an extension and/or retraction of the guide plate. The cleaning device includes brushes which are in contact with upper and lower surfaces of the guide plate, and detergent containers which support the brushes and receive detergent therein. The detergent containers include detergent inlets so as to allow the detergent to be injected to the brushes. Since the guide plate slides and is in contact with the brushes containing the detergent, the guide plate is always maintained in a clean condition. That is, the cleaning operation of the guide plate is automatically performed in response to a moving operation of the guide plate.Type: GrantFiled: December 12, 2002Date of Patent: April 13, 2004Assignee: Samsung Electronics Co., LtdInventor: Ha-Yeong Yang

Patent number: 6028298Abstract: A microwave oven includes a turntable disposed in a cooking chamber. The turntable is seated on rollers which are driven about horizontal axes to rotate the turntable. The rollers are mounted on elements that can be raised and lowered, whereby the turntable is raised and lowered while being rotated. A drive mechanism which raises and lowers the rollers is reversible whereby the turntable is rotated in a first direction while being raised, and in a second direction while being lowered. Position detectors sense when the turntable has reached maximum upper and lower positions for reversing the drive mechanism.Type: GrantFiled: October 17, 1996Date of Patent: February 22, 2000Assignee: Samsung Electronics Co., Ltd.Inventor: Ha-Yeong Yang

Patent number: 5945023Abstract: A microwave oven includes a cooking chamber and an electronic component compartment separated from one another by a partition wall. Air inlet holes are formed in an upper portion of the partition wall, and air outlet holes are formed in another wall of the cooking chamber to enable air to be circulated through the cooking chamber by a fan disposed in the electrical component compartment. First drain holes are formed in a lower portion of the partition wall diagonally opposite the air inlet holes to enable condensed moisture formed in the cooking chamber to drain into the electrical component compartment. That moisture exits the electrical component chamber through second drain holes formed in the floor of the electrical component compartment. A barrier is disposed in the electrical component compartment to surround the first and second drain holes, thereby preventing moisture from reaching any of the electrical components.Type: GrantFiled: April 23, 1998Date of Patent: August 31, 1999Assignee: Samsung Electronics Co., Ltd.Inventor: Ha-yeong Yang
