Patent ID: 8286369

Claim:
A laundry dryer, which comprises at least one receiving area for laundry and at least two electrodes for measuring the conductance of the laundry, whereby at least one of the electrodes at least partially borders on the receiving area, the laundry dryer including cooling means for cooling at least a part of at least one of the electrodes; a laundry drum defining the receiving area for receiving laundry; a sensor for measuring the amount of moisture in the laundry, the sensor including the at least one of the electrodes, the at least one of the electrodes having an outer surface exposed to the receiving area; an air intake receiving a cool air flow; and an air passageway directing at least a portion of the cool air flow to the sensor to cool the at least one of the electrodes and resist formation of deposits on the at least one of the electrodes, wherein the sensor includes the at least one of the electrodes being connected to a base component defining an opening in fluid communication with the air passageway for providing the cool air flow to pass through the base component and contact the at least one of the electrodes, and the at least one of the electrodes is formed as an elongated trough-shaped member defining an internal cavity, the outer surface of the at least one of the electrodes facing away from the base component and the internal cavity facing toward the base component and being in fluid communication with the opening and receiving the cool air flow from the opening.
