Abstract

A magnetron includes a ring-shaped anode, a cathode, an activating space, at least one permanent magnet and a magnetic flux carrying unit. The ring-shaped anode forms a plurality of resonance circuits. The cathode is disposed at the axial center of the anode to emit thermions. The activating space is formed between the anode and the cathode. The at least one permanent magnet is provided beside the anode. The magnetic flux carrying unit carries magnetic flux generated by the at least one permanent magnet to the activating space. A microwave oven and / or high frequency heating apparatus may utilize the magnetron.

Description

technical field [0001] The present invention generally relates to magnetrons, microwave ovens and high-frequency heating equipment equipped with magnetrons, and in particular to improvements in the arrangement of magnets for applying magnetic flux in their activation spaces and changes in the shape of the upper and lower yokes corresponding to the arrangement improvements Magnetrons and microwave ovens and high-frequency heating equipment equipped with such magnetrons. Background technique [0002] The conventional magnetron structure is illustrated in the accompanying drawings. like figure 1 As shown, in a conventional magnetron, a plurality of vanes 102 forming an anode and an anode cylinder 101 are arranged at regular intervals along the radial direction to form a resonant circuit. The antenna 103 is connected to one of the blades 102 and transmits harmonics to the outside, and the blades 102 are connected alternately through two pairs of strip rings 108 . Also, a cath...
