A home laundry drier () comprising an outer box casing () and, inside the casing, a laundry drying container () for housing the laundry to be dried, a hot-air generator () for circulating a stream of hot air inside said laundry drying container (), and a steam generator () for feeding steam into said laundry drying container (); the steam generator () comprising a steam-generating boiler () designed to receive water and convert it into a stream of low-pressure steam whose pressure is higher than external pressure, a steam injection nozzle () structured for projecting jets of low-pressure steam directly inside the laundry drying container (), and a steam exhaust manifold () connecting the outlet of the steam-generating boiler () to the steam injection nozzle () for feeding the low-pressure steam produced by the steam-generating boiler () directly to said steam injection nozzle (); the steam injection nozzle () being located over the steam-generating boiler (), and said steam exhaust manifold () being dimensioned so that the maximum speed (V) of the low-pressure steam flowing along at least one portion of said steam exhaust manifold () is lower than 9 m/s, so to cause the natural flowing of the water droplets resulting from steam condensation inside the steam exhaust manifold () back to the outlet of the steam-generating boiler ().

A clothes drying machine comprises a drum (), a first fan () blowing a first flow of drying air through a drying-air conduit, a condenser () through which said flow of drying air passes, a cooling-air conduit conveying a second flow of fresh air through said condenser, said second flow being circulated by a second fan (), and a motor adapted to drive said fans. There is provided an additional condensation element () run in parallel of said conduit of drying air, and a respective second air conduit connecting said additional condensation element to said drying air conduit; said additional condensation element is cooled by air at room temperature inside the dryer machine and/or by a wall of it, and the water there condensed is being passed to a common condense recovery reservoir ().

Drain pump for clothes washing machines, comprising: an impeller having vanes () that are arranged on respective planes passing through the axis of said rotating shaft, said drain manifold being provided with a planar inner wall (), in which there is provided a hollow space or separating gap () between said vanes of the pump impeller and said planar inner wall of said drain manifold, in which there are arranged a plurality of planar members () provided integral with said impeller and arranged in respective planes extending parallel to the axis of said rotating shaft (). Said planar members have a height that is smaller than the height of said vanes, but greater than the largest radius of the central hub of said rotating shaft.

Drain pump

A washing aid dispenser for a washing machine comprises at least a compartment, which is adapted to contain washing aids and is provided with a first siphon having a pre-determined suction height and at least a second siphon having a higher suction height than the first siphon. The first and the second siphon are adapted to draw in and convey towards a washing tub of the machine layers of the washing aids mixed with water lying at different heights in the dispenser.

Washing aid dispenser and washing machine comprising said dispenser

Clothes drying machine comprising a rotating drum, an exhaust conduit into which flows the air issuing from the outlet aperture of the drum, a lint filter formed in the shape of a sector of a cylindrical surface, which is arranged in said exhaust conduit below said outlet aperture of the drum, with the axis thereof extending substantially parallel to the axis of rotation of the drum, in which there are provided automatic means adapted to ensure cleaning of said filter through a brushing action; said automatic means comprise a brush connected to an end portion of a moving arm, which is hinged, on the other end portion thereof opposite to said brush, on to a rotation pin, said moving arm being slidably linked with a driving pin which is rotating, by means of a respective rotation arm, about a driving spindle that is driven rotatably about its own axis by automatic driving devices.

Centrifugal pump, in particular drain pump for washing machines, comprising a casing () that defines a chamber () within which an impeller formed by a hub () and a disk () provided with blades () is capable of rotating. The impeller is provided with at least a slit () adapted to generate a negative pressure on the rear surface of the disk () during the rotation of said impeller. The solution is very simple and rational; it enables a clogging of the impeller, as it may be caused by the presence of foreign matters and bodies in the washing liquor, to be avoided. It also enables axial thrusts, as they occur during the rotation of the impeller, to be compensated for.

Centrifugal pump

Dishwashing machine comprising a programme sequence control unit, at least two rotating spray arms, a circulation pump () capable of operating even intermittently, a distribution valve () arranged directly on the delivery-side section () of the pump () and having at least a first and a second outlet () which communicate with a respective rotating spray arm. The shutter member () of the valve, in accordance with the flow direction of the liquor at the delivery side () of the pump, is adapted to selectively displace both between said first and second outlets () and into an intermediate seat () situated between the same outlets. The duration of the pauses in the intermittent operation of the pump (), as controlled by the programme sequence control unit, is correlated to the actual pressure at the inlet of the valve () by the action of means () provided to monitor the localized pressure of the liquor.

Dishwashing machine with improved washing liquor distribution valve

Dishwashing machine with a distribution valve ( ) which is arranged on the delivery-side section of the washing liquor circulation pump and is provided with at least two outlets ( ) connected via associated conduits ( ) to rotating spray arms, as well as at least a shutter means ( ). The shutter means ( ) is not only adapted to be alternately displaced from a position in which it enables liquor to be delivered to at least a rotating spray arm to a position in which it enables a second rotating spray arm to be supplied with liquor, in accordance with a programmed stop time (D ) of the pump, but is also adapted to be displaced into a further position in which it enables liquor to be delivered to at least two rotating spray arms at the same time, in accordance with a second stop time (D ) of the same pump.
