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： A plate-type magnetron has a cathode (13) for emitting electrons and plate shaped anode (11) having a multiple number of vanes (12) arranged at regular intervals thereon, forming an interaction space (18). Provided on both sides of the interaction space are a pair of pole pieces (14) which are formed of bellows, and hence flexible in their length, and an adjustable magnetic portion (16). A yoke (15) is provided, which is used to alter the distance between the magnets, so that the frequency of the microwaves can be changed. A pair of electrodes (20) arranged facing each other perpendicularly to the magnetic field on both sides of the interaction space (18) is also provided, and the applied voltage to the electrodes is changed to thereby change the output power of microwaves.

摘要： In a magnetron, anode vanes (23) are radially arranged in an anode cylinder (22) and fixed to the inner surface of the anode cylinder (22) and a cathode (25) is arrange along a tube axis in the anode cylinder (22). A pole pieces (29, 30) of dish like shape are fixed to openings of the anode cylinder (22) and the anode cylinder (22) is hearmetically sealed by cylindrical chambers (32, 33). Permanent magnet rings (34, 35) are arranged around the cylindrical chambers (32, 33), respectively and are magnetically coupled by a yoke (36). Each of pole pieces (29, 30) has a flange section (29b, 30b), a flat inner disk section (29a, 30a) and a coupling section (29c, 30c) extending from flange section (29b, 30b) to flat inner disk section (29, 30a). The outer diameter of pole piece (29, 30) is larger than 160% the diameter of an envelope defined by inner ends of said anode vanes (23). A envelope space contacting the inner ends of said anode vanes has a predetermined magnetic field intensity distribution which is produced by a magnetic flux supplied from pole piece (29, 30) and has a difference of not more than 15% along tube axis.

By shortening the height of vane Vh so that the ratio of the height of vane Vh to a gap between end hats EHg (EHg/Vh) satisfies a condition 1.12≦EHg/Vh≦1.26, an input side pole piece-vane gap IPpvg becomes larger than an output side pole piece-vane gap OPpvg, and an input side end hat-vane gap IPevg becomes larger than an output side end hat-vane gap OPevg, load stability at high efficiency can be improved while shortening the height of vane Vh. Therefore, it is possible to provide a magnetron improved in high efficiency and load stability while suppressing costs.

The compact magnetic field generator includes a plurality of permanent magnets including: a cathode magnet that has a longitudinal axis of symmetry annularly and that is surrounded by the cathode and disposed within the magnetron; and an anode magnet configured to annularly surround an outer perimeter of the magnetron. An arrangement of the plurality of permanent magnets concentrically about the longitudinal axis of symmetry forms a specified magnetic field within the interaction region that bounds the electrons emitted within the interaction region.

摘要： A magnetron includes an anode with an anode casing at least partly surrounding the anode. A pair of permanent magnets on each side of the anode define an interaction region and create a magnetic circuit defining a magnetic field through the interaction region. A mass of magnetically permeable material is positioned in a vicinity of the magnetic circuit. The mass is arranged to be slidable over the anode casing. A locking device secures the position of the mass to set the strength of the magnetic field through the interaction region.
