Abstract
A magnetron for microwave ovens includes a positive polar cylinder, a cathode, and a plurality of vanes. The vanes constitute a positive polar section along with the positive polar cylinder. Each of the vanes is provided with a first depression to allow a large-diameter strip ring to be disposed therein, and a second depression to allow a small-diameter strip ring to be disposed therein. Each vane is provided at a cathode-side corner of the first depression with a thermion travel passage to allow thermions to smoothly flow without the hindrance of the first depression.

A magnetron for microwave ovens, comprising:
- a positive polar cylinder;
- a cathode;
- and
- a plurality of vanes to constitute a positive polar section along with the positive polar cylinder, each of the vanes being provided with a first depression to allow a large-diameter strip ring to be disposed therein, and a second depression to allow a small-diameter strip ring to be disposed therein,
- wherein the vane is provided at a cathode-side corner of the first depression with a thermion travel passage to allow thermions to smoothly flow without hindrance of the first depression.
A magnetron for microwave ovens, comprising:
- a positive polar cylinder;
- a cathode;
- and
- a plurality of vanes to constitute a positive polar section along with the positive polar cylinder,
- wherein rectangular protrusions are provided at depressions of the vanes to form a thermion travel passage, thereby allowing thermions to smoothly flow from one of the vanes to another vane.
