Patent attributes
A clothes drying appliance includes a cabinet and a drum inside the cabinet supported on a drum support structure. A belt passes around the drive pulley of a drive motor and around the drum for driving rotation of the drum in either direction. A belt tensioning device includes a pair of spaced apart tensioning pulleys each having an axis of rotation substantially parallel with the axis of rotation of the drive pulley. An imaginary line between the centres of the tensioning pulleys separates the drive pulley from the drum. The pulleys are supported on a yoke and the yoke passes around the drive pulley, with the tensioning pulleys spaced sufficiently close to impinge upon the path of the belt passing around the pulley and drum. A biasing agent such as a spring presses the pulleys toward the drum by urging the yoke toward the pulley.
