Abstract: A dispenser of washing agents for washing machines has a first tank, to contain a first washing agent, and a first dispensing arrangement, to dispense first dosed amounts of the first washing agent. The first dispensing arrangement comprises a peristaltic pump, which is configured to be driven in a first direction of rotation to cause delivery of the first dosed amounts of the first washing agent. The dispenser comprises a second tank, to contain a second washing agent, and a second dispensing arrangement, to dispense second dosed amounts of the second washing agent. The peristaltic pump has a command arrangement of the second dispensing arrangement, and is configured to be driven in a second direction of rotation, to drive the command arrangement so as to cause dispensing of the second dosed amounts of the second washing agent.

Abstract: A washing agent dispenser for washing machines has a dispenser body that comprises a fixed dispenser part (200), designed for mounting on a wall delimiting a washing machine wash-chamber (3), and a removable dispenser part, couplable in a removable way to the fixed dispenser part (200). The removable dispenser part comprises a hollow body defining a tank for a substance in liquid or semi-solid form, with a first wall of the hollow body which is intended to face at least partially a second wall of the fixed dispenser part (200). The dispenser (10) also comprises a sensor device (270), configured to provide an electrical signal representative of at least one of a level and a qualitative characteristic of the substance contained within the at least one tank. The sensor device (270) is arranged at least partly on the fixed dispenser part (200).

Abstract: A washing agent dispenser for washing machines comprises a fixed dispenser part (200) and a removable dispenser part (100). The removable dispenser part (100) comprises a hollow body (101) defining a tank for a washing agent. The tank has, in a lower part thereof, an outlet (112), in a back wall of the hollow body (101), which is couplable in a separable way to an inlet (210) at the front of the fixed dispenser part (200). A retention valve (2301) is mounted on the hollow body (101), in a position corresponding to the outlet (112) of at the tank. The retention valve (2301) is configured to assume a respective open position following upon coupling between the outlet (112) and the inlet (210), and to assume a respective closed position following upon uncoupling between the outlet (112) and the inlet (210).

Abstract: A washing agent dispenser for washing machines has a dispenser body (100) designed for mounting on a wall (5) delimiting a washing machine wash-chamber, the dispenser body (100) being designed to be exposed at least in part towards inside the washing machine wash-chamber (3). A tank (R1) capable of containing a substance in liquid or semi-solid form is defined in the dispenser body (100), and the dispenser (10) comprises a dispensing arrangement which is configured for dispensing first dosed amounts of the substance. The dispenser moreover comprises a sensor device configured to provide an electrical signal representative of at least one qualitative characteristic of the substance contained within the tank (R1).

Abstract: A bearing detection device comprises: a housing body (2) having a substantially annular shape, prearranged for being fixed to a stationary ring (6a) of a bearing (6); and a detection arrangement on the housing body (2), comprising at least one piezoelectric transducer (10; 20). The detection arrangement further comprises: a floating body (7) having a substantially annular shape, which is mounted within the housing body (2) and is able to amplify mechanically vibrations of the bearing (6); a sensor unit (8) having a substantially annular shape, which is set in a substantially stationary position on the housing body (2), the supporting body (81) having a detection surface (8a) that is configured for receiving thereon, directly or via interposition of at least one further element, a corresponding surface of the floating body (7).

Abstract: A sensorized supporting device for bearings (1) comprises: •a bearing housing (2), configured for being secured to a mounting structure and defining at least one seat (2c) for a bearing (3); and •a sensorized supporting base (4), having a supporting body (4?) prearranged for being at least partially positioned between the mounting structure (S) and the bearing housing (2). The supporting body (4?) has a detection surface (4c) which extends in a longitudinal direction (L) and a transverse direction (W) and is configured for resting, directly or via interposition of at least one further element, on a corresponding surface of one of the bearing housing (2) and the mounting structure, the supporting base (4) being provided with a mechanical-stress sensor.

Abstract: A level sensor comprises an electrical-connection structure and a level-detection structure. The level-detection structure comprises a plurality of elongated electrodes, which include at least three measuring electrodes. The elongated electrodes extend at least partially in side-by-sidey positions in a length direction of the level-detection structure and each have a proximal end and a distal end relative to the electrical-connection structure. The level-detection structure is divided, in the length direction, into a succession of detection sections, each of which includes two effective portions of two respective measuring electrodes, the two effective portions extending to a prevalent extent substantially parallel and equidistant, at a first predetermined distance from each other, in the length direction.

Abstract: A mechanical-stress sensor comprises a piezoelectric transducer (10), which is able to generate an electrical signal representing a shear stress. The piezoelectric transducer (10) comprises: a layer of piezoelectric material (11), which extends in a longitudinal direction and has a polarization axis (A), which extends in a direction transverse to the longitudinal direction; and at least one first electrode (E1) and one second electrode (E2), each having a plurality of fingers (F1, F2), which extend at a first major face and a second major face, respectively, of the layer of piezoelectric material (11).
