Abstract: A laundry treatment apparatus, in particular a dryer or a washing machine having a dryer function, and a method for operating the apparatus are disclosed. The apparatus includes a laundry treatment chamber (18) for treating laundry using process air (A), a blower (8) for circulating the process air (A) within the laundry treatment chamber (18); and at least one temperature sensor (27, 28, 29).

Abstract: A method is provided for controlling a motor speed (v) of a motor (16) in a laundry dryer during a drying cycle, which motor (16) is provided for driving a laundry drum (20) and an air stream fan (14) of the laundry dryer. The drying cycle is subdivided into a first part and a second part. During the first part of the drying cycle the motor speed (v) takes a value of a first predetermined motor speed (v1). During the second part of the drying cycle the motor speed (v) takes a value of a second predetermined motor speed (v2). The value of the second predetermined motor speed (v2) is higher than the value of the first predetermined motor speed (v1) and allows laundry tumbling inside the drum (20). The drying cycle changes from the first part to the second part, when laundry dryness (38) of laundry inside the laundry drum (20) has reached a predetermined value.

Abstract: A tumble dryer (100) is provided having: a laundry drum (102) rotatably supported in a casing (110) and suitable to receive laundry to be dried. A lint filter assembly (1) can be housed in a housing (105) provided in the casing (110) so that, when the lint filter assembly (1) is placed in the housing (105), it intercepts a flow of air exiting the laundry drum (102). A humidity sensor system retrieves information about the actual humidity of the laundry in the drum (102) and has at least a pair of electrodes (20) positioned such that the laundry in the drum (102) can come into contact with the electrodes (20). A control unit (150) controls the operations of the tumble dryer; and an electric circuit (21, 22, 23) transmits a signal obtained from the electrodes (20) to the control unit (150).

Abstract: A home laundry drier (1) includes a laundry drum (4) which is located inside a casing (3) to rotate about an longitudinal axis (A), and a closed circuit hot-air generator (7) provided with: an air recirculating conduit (8) connected to laundry drum (4); a centrifugal fan (9) and heat-pump means (10). The heat pump means (10) includes first (12) and second air/refrigerant heat exchangers (13) located in the air recirculating conduit (8) to cool the airflow coming out from the laundry drum, and respectively, to heat the airflow returning back into laundry drum (4). The home laundry drier (1) further includes an electric motor (14) designed to simultaneously rotate both centrifugal fan (9) and the laundry drum (4) through transmission system means (16); and inverter means (23) controlling the electric motor (14) and configured to receive a predetermined speed which is associated to a nominal airflow rate within the air recirculating conduit (8) and to a nominal drum speed.

Abstract: A home laundry drier (1) is provided with a heat-pump assembly (11) having a refrigerant compressing device (15) which is connected to a supporting wall (2b) of the casing (2) via one or more vibration dampers (17) structured for floatingly supporting the refrigerant compressing device (15). At least one of the vibration dampers (17) includes an elastically-deformable hollow body (18), and a central retaining rod (20) which extends through the elastically-deformable hollow body (18). The central retaining rod (20) is axially displaceable between a locking position in which a head portion (20b) of the rod (20) compresses the elastically-deformable hollow body (18) so as to rigidly connect the compressor (15) to the supporting wall (2b) of the casing (2) and a unlocking position in which the elastically-deformable hollow body (18) floatingly supports the refrigerant compressing device (15).
