Abstract:
A dishwasher comprising: i) a washing compartment (2) for washing dishes; ii) a door (3) that is movable between an open position, wherein it enables the insertion and removal of the dishes in/from the washing compartment (2), and a closed position, wherein it is substantially vertical and closes an access opening (20) to the washing compartment (2); iii) projection means (4) for projecting a pre-established light signal on a surface external to the dishwasher, the light signal being associated with the washing state in progress or alternatively, with the achievement of the end-of-wash state, said projection means (4) comprising a light source (40). The projection means (4) comprises a concentration lens (41) for concentrating a light beam coming from the light source (40), said concentration lens (41) being external to the door (3) and solidly constrained to a frame (42) that encloses said access opening (20); The light beam is projected by the lens (41) towards the exterior of the dishwasher. Downstream of the lens (41), the light beam extends in a substantially horizontal direction. Downstream of the lens (41), the light beam intersects an imaginary vertical upwards projection of an upper edge (30) of the door (3) considered in the closed position.
Abstract:
The present invention relates to a sprinkler device for a liquid (1), comprising an annular fixing element (2) adapted to be connected to a hydraulic duct (103), and a substantially conical distribution element (3) comprising a conical vertex facing towards the annular fixing element (2) and adapted to distribute a liquid flow coming from the hydraulic duct (103), and further comprising a plurality of holding arms (4) structurally connecting the annular fixing element (2) to the distribution element (3) at a predetermined distance. The present invention also relates to a household washing appliance, particularly to a dishwashing machine; it further refers to a method for manufacturing a sprinkler device for a liquid, and to a method for controlling a household washing appliance, particularly a dishwashing machine.
Abstract:
The present invention relates to a household appliance comprising a standby switch (10) adapted to take a first standby position, in which it breaks the current flow on a power supply line in order to place the household appliance into standby mode, and a second position, in which the household appliance is operational, a sensor (8) adapted to detect an event which may be associated with a fault of the household appliance, characterised in that it comprises wake-up means (6,11,14) operating when the household appliance is in standby and adapted to bring said standby switch (10) into said second position when said sensor (8) detects said event.

Abstract:
A dish-washing machine has a washtub, in which there can be housed at least one lower dish rack and one upper dish rack, and a sprinkler system, which comprises a lower sprinkler device configured for spraying water upwards, towards the lower rack, and at least one of an intermediate sprinkler device, configured for spraying water upwards, towards the upper rack, and an upper sprinkler device, configured for spraying water downwards, towards the lower rack. The lower sprinkler device and the at least one of the intermediate sprinkler device and the upper sprinkler device comprise respective rotary sprinklers, the at least one of the intermediate sprinkler device and the upper sprinkler device being supplied via a canalization (12) having at least one first portion (12a) and one second portion (12b), and possibly one third portion, which extend substantially at a lower wall, a rear wall and an upper wall of the tub, respectively. The sprinkler system comprises at least one further stationary sprinkler device (13) within the tub, configured for spraying water towards one of the lower rack and the upper rack, in fluid communication with a duct (14, 15) of the canalization (12). The further stationary sprinkler device (13) has a hollow body (25) with a coupling portion (25a) having, on a rear side thereof facing the canalization (12), at least one of mechanical-coupling means (27) and hydraulic-coupling means (33) for coupling to the canalization (12), which are configured for quick coupling with respect to corresponding mechanical-coupling means (32) and hydraulic-coupling means (34) provided in a corresponding coupling portion of the canalization (12). The coupling portions of the canalization (12) and of the hollow body preferably have both the respective mechanical-coupling means (27, 32) and the respective hydraulic-coupling means (33, 34).
