SPACE-EFFICIENT CHOKE SYSTEM FOR CONTAINING RF LEAKAGE

摘要

A choke assembly for provision onto an oven door to seal radio frequency (RF) energy within the oven when the door is closed may include a capacitive coupling element and an inductive tuning element. The capacitive coupling element may include a plurality of tabs each having a first width. The inductive tuning element may include a plurality of projections bent relative to the capacitive coupling elements at a right angle, the projections each having a second width that is smaller than the first width.

主权项

1. An oven comprising:
a radio frequency (RF) source; a cooking chamber into which RF energy is providable via the RF source; a door configured to hingedly operate to alternately allow access to the cooking chamber and close the cooking chamber for cooking; and a choke assembly disposed to seal a region between the door and walls of the oven that define the cooking chamber from RF leakage responsive to closure of the door, wherein the choke assembly comprises:
a capacitive coupling element comprising a plurality of tabs each having a first width; andan inductive tuning element comprising a plurality of projections bent relative to the capacitive coupling elements at a right angle, the projections each having a second width that is smaller than the first width.
