Abstract: A laundry washing machine having an outer casing, a washing tub, a rotatable drum and at least one balancing ring rigidly secured to the drum for reducing vibrations thereof. The balancing ring comprises an annular housing rigidly secured to the drum, an internal closed annular inner cavity, and balancing masses in free movable manner inside the annular inner cavity. The annular housing has first and second discrete and complementary annular hemishells that are joined to one another to form the annular inner cavity. The annular hemishells are substantially coplanar and concentric to one another, and have approximately C-shaped cross sections that are substantially complementary to one another. The hemishells are joined to one another along corresponding first and second mating annular rims, which are arranged on opposite sides of a given intermediate plane perpendicular to the central axis of the annular housing.

Abstract: A laundry washing machine having an outer casing, a washing tub, a rotatable drum and at least one balancing ring rigidly secured to the rotatable drum. The at least one balancing ring includes a substantially toroidal, annular housing that is rigidly secured to the drum, and has a tubular structure so as to delimit a closed annular inner cavity. A number of balancing masses are accommodated in movable manner inside the annular inner cavity, preferably together with a damping liquid. The annular housing has a substantially frustoconical outer wall segment that is inclined by an angle (?) lower than 90° with respect to the midplane (P) of the annular housing, and a peripheral supporting structure that juts out outwardly from the substantially frustoconical outer wall segment to stably abut against the body of the drum.

Abstract: The present invention relates to a laundry treating machine (10) comprising at least one electric motor (22) and at least one inverter control device (24) for controlling the rotational speed of said electric motor (22), wherein the electric motor (22) is provided for driving a laundry drum (40), an air stream fan (20), a cooling air fan (34) and/or a heat pump compressor (18), and wherein the inverter control device (24) is controlled again by a control unit (52) of the laundry treating machine (10). The control unit (52) comprises or corresponds with a detection device for detecting the frequency of a main power supply connected to the laundry treating machine (10), wherein the control unit (52) and/or the inverter control device (24) control the electric motor (22) on the basis of one or more operating parameters depending on the detected frequency of the main power supply.

Abstract: The present invention relates to a laundry treating appliance, such as a washing machine or a machine having laundry drying functions; a laundry treating appliance according to the invention comprises a cabinet assembly (1) including a front wall (3), a rear wall (4), side panels (31, 32) arranged between the front and rear walls (3, 4) and one or more beam elements (10) for structurally connecting the front and rear walls (3, 4), the cabinet assembly (1) accommodating operational components which are required for carrying out a treatment on laundry and a control unit device designed to control the operational components, the appliance having one of the beam elements (10) made of an electrical insulating material and formed as a box member (6) having an interior housing (50) for accommodating the control unit device therein.

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.
