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 ().

Household-type front loading and water-recirculating clothes washing machine adapted to automatically measure the weight of the dry clothes loaded in the machine for washing, also on the basis of the information on the type of clothes in said washload entered from the outside (user), in which the measurement of such weight of the washload is performed by measuring the amount of water that is absorbed by the clothes in the washload when this is soaked with water to a point at which it is in a dynamic saturation, i.e. steady-state condition. Said measurement of the amount of water absorbed in the clothes is obtained by subtracting the amount of water that is present in the machine, and that does not interact with the washload, from the total amount of water let into the wash tub. The weight of the load of clothes is finally calculated by processing and interpolating the amount of absorbed water and rectifying such value with an information on the properties of the clothes in the washload.
