摘要： A magnetron for a microwave oven includes a yoke (20), an anode cylindrical body (30) installed inside the yoke (20), a plurality of vanes (40) mounted inside the anode cylindrical body (30), a filament (50) installed in a center of the vanes, and an upper magnet (60a) and a lower magnet (60b) respectively mounted on an upper side and a lower side of the anode cylindrical body (30). The magnetron also includes an upper pole piece (70a) and a lower pole piece (70b) respectively installed between the anode cylindrical body (30) and the upper and lower magnets (60a,60b). A length (L) from an external tip of a central part (74) of the upper pole piece (70a) to an internal tip thereof, on which a hollow part (73) 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.

摘要： An anode structure for a magnetron includes T-shape anode vanes 3 having a radially extensive component 3a and a circumferentially extensive portion 3b, the cylindrical faces 3c of the circumferential portions 3b facing a cathode in the complete magnetron. The use of T-shape vanes increases inductance and hence permits low frequency radiation to be generated without increasing the dimensions of the magnetron compared to those of a conventional magnetron. Also, capacitance is increased to give a further reduction in frequency by using more than two anode straps, and preferably four anode straps 5 to 8, at each end of the anode structure. Preferably, the anode structure is incorporated in a magnetron in which a high magnetic field of the order of 500 Gauss for a magnetron operating at 100 MHz is used. The anode shell 2 itself may form part of the magnetic return path.

摘要： An anode cylinder and a permanent magnet are efficiently cooled, and a cooling member per se is prevented from being upsized while suppressing a variation of a cooling performance for the permanent magnet. A magnetron according to the present invention includes: an anode cylinder; permanent magnets disposed on both ends of the anode cylinder; a magnetic yoke which stores the anode cylinder and the permanent magnets therein; a cooling member which stores the anode cylinder therein and which has at least a part thereof fixed to the anode cylinder; and a connection portion arranged between the magnetic yoke and the cooling member.

摘要： Provided is a low-cost magnetron that is excellent in productivity without any adverse effect on characteristics. Two large and small strap rings 11 (11A and 11B) are only disposed at lower ends, or input sides, of a plurality of vanes 10 (10A and 10B) in the direction of a tube axis m. Diameter Rip of a protruding flat surface 41 of an input side pole piece 18 is larger than diameter Rop of a protruding flat surface 40 of an output side pole piece 17. Therefore, it is possible to provide a practical magnetron without a significant decrease in productivity or characteristics from a conventional one, while cutting costs by reducing the number of parts with the use of two strap rings on one side.
