Laundry drying machine with vibrating fluff filter

Abstract

A laundry drying machine () includes a casing () containing a rotatable drum () for holding the laundry () to dry, and a drying air circuit () for conveying a drying air flow towards the inside of the drum () and from it to the outside. At least one filter () is provided for intercepting the fluff dragged out of the laundry () by the drying air flow. Vibrating means () are adapted to cause the filter () to vibrate, so as to drop down the fluff from the filter (). The filter () is selectively positionable between an operational position in which the filter () is arranged in a seat () intercepting the drying air circuit (), and an extracted position in which the filter () is removed from the seat (), outside the drying air circuit (). The vibrating means includes an exciter, associated to the casing (), and an exciter-responsive element, associated to the filter (). The exciter and the exciter-responsive element are adapted to reciprocally cooperate in order to cause the filter () to vibrate when the filter () is in the operational position. The exciter and the exciter-responsive element are configured to allow the filter () to be extracted from and inserted in the seat ().
