Abstract
Microwave clothes dryer with a moisture sensor having an array of short coaxial cables extending through an electrically conductive base plate which is grounded to the shielding structure of the dryer. The ends of the cables are flush with one side of the plate and are exposed for contact with clothes in the dryer chamber. Electrical resistance is monitored between the inner conductors and the plate to determine the dryness of clothes, and the dryer is shut down when the resistance reaches a predetermined level.
