A thermal system (1) comprises a primary water circuit (2) with a zone distributor (21), a thermal generator (22) and a primary circulator (24), a plurality of zone water circuits (3) connected to the zone distributor (21) and each provided with a respective zone circulator (31), wherein at least one mixed zone circuit (3') is connected to the zone distributor (21) via a mixing valve (35), and a control system (4) which: - selects, among all the zone circuits (3), a guide zone circuit with a thermal power demand signal, and - determines a power (P) of the thermal generator (22) as a function of a difference between a zone target temperature and a detected zone temperature of the guide zone circuit, in such a way that the greater the absolute value of the difference (T_set_zone - T_zone) of the guide zone circuit, the greater the power (P) of the thermal generator (22), and - only if the guide zone circuit is a mixed zone circuit (3') with the mixing valve (35) only partially open, further determines the power (P) of the thermal generator (22) also as a function of a mitigating value (T_mitigate) which reduces the power (P) of the thermal generator (22).

A detergent dispensing device (9) for a washing machine (1) with a detergent drawer (21) forming detergent compartments (22) and an ultrasound cleaning device (24) with an ultrasound generator (25) connected to a cleaning compartment (22') of the detergent compartments (22) to transmit ultrasound pulses into the cleaning compartment (22'), a water filling and draining system (26) of the cleaning compartment (22') to supply water into the cleaning compartment (22') until a cleaning water level (33) is reached, maintain the cleaning water level (33) inside the cleaning compartment (22') without continuous water supply, and drain water from the cleaning compartment (22'), in which the cleaning compartment (22') performs a dual function as a detergent compartment (22), to receive, retain and release a laundry treatment substance without activation of the ultrasound generator, and as a compartment for ultrasound cleaning of objects by activating the ultrasound generator.

An inlet box (100) unit includes a housing (10) including an opening (3h), a lid (1) attached to the housing (10) and configured to be movable between a fully closed position in which the opening is closed and a fully opened position in which the opening (3) is opened, a drain hole portion (7) formed in the housing (10), and a drain pipe (6) retained by the drain hole portion (7). The drain hole portion (7) includes a hole wall portion (8), and a fitting groove (9) into which the drain pipe (6) is fitted is formed in the hole wall portion (8).

A protective cover (2) for a radial fan (1) comprises a bowl-shaped body (20) forming a bottom wall (21) on an outer side (22) of the protective cover (2) intended to face away from the impeller housing (3), and a peripheral wall (23) extending from the bottom wall (21) towards an inner side (24) of the protective cover (2) and delimiting together with the bottom wall (21) a motor space (47) for accommodating an electric motor (11) and an electric control board (19) of the fan, a first connection edge (25) formed by the peripheral wall (23) and intended to face and/or rest from the outside against an impeller housing of the fan. The body (20) is made in several parts and comprises a first closed-loop half-body (30) forming at least a part of the peripheral wall (23) with the first connection edge (25) and with a second connection edge (31) opposite the first connection edge (25) and facing the outer side (22), and a second half-body (32) forming the bottom wall (21) with a third connection edge (33) facing the inner side (24) and complementary to the second connection edge (31).

A stator (4) - electric board (11) assembly of an electric motor (3) comprises a stator (4), a bearing-carrier hub (8) inserted into the stator (4) for supporting and centering a rotor shaft (10), an electric board (11), and an insulating body (14) made of polymer resin overmolded by injection on and around the stator (4), the bearing-carrier hub (8), and the electric board (11) so as to completely fill the gaps formed therebetween and join the stator (4), the bearing-carrier hub (8), and the electric board (11) in a single self-supporting body, in which a front surface (23) of a connection flange (25) of the bearing-carrier hub (8) and contact terminals (17) of the electric board (11) are oriented axially with respect to a motor axis (19) toward the outside of the stator (4) - electric board (11) assembly on the same connection side (20) and positioned outside the insulating body (14), exposed and accessible.

An impact wrench (1) with an upper handle assembly (2), a lower working assembly (3) and an intermediate connecting bar (4) connected between the handle assembly (2) and the working assembly (3) and comprising a tubular body (4') with a first end portion (15) coupled with a first coupling seat (16) of the handle assembly (2) and a second end portion (17) coupled with a second coupling seat (18) of the working assembly (3), wherein the first end portion (15) and the first coupling seat (16) both have a non-circular or polygonal or rectangular or square cross-section, orthogonal to the longitudinal direction (14), , so as to make an anti-rotation shape coupling with the interposition of a first damping assembly (24) forming a damping layer between the first end portion (15) and the first coupling seat (16).
