Patent number: 7122773Abstract: A magnetron for microwave ovens includes an anode cylinder, a plurality of plate-shaped vanes radially arranged along an inside surface of the anode cylinder, one or more strap rings to electrically connect the plurality of plate-shaped vanes to each other, an antenna connected to one of the plurality of vanes to radiate microwaves generated from the plurality of vanes. Each of the vanes is plated with a brazing material to be brazed to one or more of the anode cylinder, the one or more strap rings and the antenna, and the brazing material has a plating depth of about 2.25 to 8 ?m. The magnetron having the anode allows a manufacturing process of the anode to be simplified to reduce manufacturing time and equipment costs. Furthermore, the anode prevents brazing defects, and allows the magnetron to have an optimal performance.Type: GrantFiled: March 4, 2004Date of Patent: October 17, 2006Assignee: Samsung Electronics Co., Ltd.Inventor: Sung Chol Yang

Patent number: 6972522Abstract: A magnetron capable of being efficiently assembled is provided. The magnetron includes a filament, a pair of shields, a pair of leads, a pair of connection plates, and a pair of terminal rods. The filament is coil-shaped. The shields are attached to both ends of the filament, respectively. The leads are attached to the shields at first ends of the leads, respectively. The connection plates are attached to second ends of the leads, respectively. The terminal rods are attached to the connection plates, respectively, to supply power to the leads through the connection plates, and have slender protrusions, which have sectional areas smaller than sectional areas of attachment portions of the terminal rods so that the terminal rods are attached to the connection plates with the slender protrusions passing through the connection plates.Type: GrantFiled: March 24, 2004Date of Patent: December 6, 2005Assignee: Samsung Electronics Co., Ltd.Inventor: Sung-Chol Yang

Patent number: 6803726Abstract: A noise filter of a high frequency generator reduces noise of a certain frequency band leaked from the high frequency generator using a structure in which a first core inductor, an air-core inductor and a second core inductor are connected in series to each other. The first and second core inductors have high frequency-energy absorbing members inserted thereinto, and the air-core inductor is not provided with a high frequency-energy absorbing member therein. The high frequency-energy absorbing member is made of one of iron oxide, tin alloy and ferrite. The high frequency-energy absorbing member is also provided with a sectional area in which noise of a frequency band of 400 MHz to 900 MHz is attenuated.Type: GrantFiled: March 21, 2003Date of Patent: October 12, 2004Assignee: Samsung Electronics Co., Ltd.Inventor: Sung-Chol Yang

Patent number: 6791268Abstract: A noise filter for a high frequency generator maximizes a frequency band in which noise is attenuated by adjusting a spacing between winding turns of core inductors provided in the noise filter. The noise filter includes a coke coil having a first winding unit having a first spacing between turns thereof, a second winding unit having a second spacing between turns thereof and a third winding unit having a spacing the same as the first spacing between turns thereof. The first, second, and third winding units are connected in series to each other. The noise filter also includes a high-frequency energy absorbing member inserted into the choke coil. The high-frequency energy absorbing member is made of one of iron oxide, tin alloy and ferrite, and includes a sectional area to attenuate noise in a frequency band ranging from 30 MHZ to 1000 MHz.Type: GrantFiled: May 23, 2003Date of Patent: September 14, 2004Assignee: Samsung Electronics Co., Ltd.Inventor: Sung-Chol Yang

Patent number: 6774568Abstract: A magnetron for a microwave oven includes a yoke, an anode cylindrical body installed inside the yoke, a plurality of veins mounted inside the anode cylindrical body, a filament installed in a center of the veins, and an upper magnet and a lower magnet respectively mounted on an upper side and a lower side of the anode cylindrical body. The magnetron also includes an upper pole piece and a lower pole piece respectively installed between the anode cylindrical body and the upper and lower magnets. A length (L) from an external tip of a central part of the upper pole piece to an internal tip thereof, on which a hollow part is formed, is adjusted to suppress harmonics in the magnetron. Thus, generation of the harmonics may be effectively attenuated, and an output of a microwave may be enhanced by preventing power consumption of the magnetron which may be large due to interrupting harmonics.Type: GrantFiled: May 30, 2003Date of Patent: August 10, 2004Assignee: Samsung Electronics Co., Ltd.Inventor: Sung-chol Yang
