Clothes drying machine comprising a drum holding the clothes to be dried, a first fan adapted to blow a first flow of drying air through said drum, and possibly a condenser adapted to condense the moisture out of the drying air exiting said drum. The machine is provided with a drying program that includes a step involving an increase in the temperature of the air introduced in said drum, in which said temperature is increased to a value of at least 130&#xb0; C. and held there for a pre-set period of time, and said temperature increase step is provided in the initial portion of the drying program, when the moisture content of the clothes is not less than 20%.

Household clothes drying machine with clothes disinfection cycle

A laundry dryer is provided with an air recirculation channel which recirculates air from an air exhaust channel to an air supply channel. The air recirculation channel comprises a recirculation air filter which removes debris from the recirculated air before it is redirected to the air supply channel. The recirculation air filter is removably accessible behind an access door at a peripheral region of an access passage to the drying chamber such that it may be easily serviced by a user of the laundry dryer. In some embodiments, the air recirculation channel may comprise a nozzle with an outlet which is concentrically arranged at an inlet of the air supply channel. In these embodiments, the nozzle may direct the recirculated air to the air supply channel such that it is enveloped by fresh air entering from within a cabinet of the laundry dryer.

Laundry dryer with accessible recirculation air filter

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 ().

Home laundry drier

Front-loading clothes washing machine including a washing tub, a rotating drum contained in the tub and provided with an access opening and a rear wall, and a plurality of internally hollow lifting ribs arranged inside the drum and provided internally with a respective partition wall. The partition wall is in the shape of a substantially planar quadrangle, a side of which coincides with the common side of the inclined walls of the lifting rib, while the opposite side lies on the inner surface of the drum in a roughly intermediate position between the walls. The partition wall divides the inner volume of the respective lifting rib into two chambers that do not communicate with each other, and each one of the inclined walls is provided with at least a first respective aperture and a plurality of respective perforations adapted to let the respective one of the chambers communicate with the inner volume of the drum.

Lifting ribs of the drum of a clothes washing machine

A home laundry drier () having a revolving drum () for housing the laundry to be dried, a hot-air generator () for circulating a stream of hot air inside the drum (), and a steam generator () for feeding steam into the drum (); the steam generator () having an electric boiler () designed to receive a given quantity of water and immediately convert it into a stream of low-pressure steam to be fed into the drum (), a demineralized-water reservoir () located over and communicating with the electric boiler (), and a lint filter () located upstream from the water reservoir (); the water reservoir () receiving distilled water from the water canister () of the heat exchanger () of the hot-air generator () via a water drain circuit (); and the laundry drier () also having a liquid level sensor () for determining when the water in the water reservoir () is below a given minimum level, and a central control unit () for determining whether the water reservoir () is in a given low-water-level condition at both the start and end of a user-selected drying cycle not including activation of the steam generator ().

Determining clog steam generator tank filter laundry drier, and apparatus

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 ().

Household clothes drying machine with additional condenser

A home laundry drier () having a drying tub () housing the laundry to be dried, and a closed-circuit, heat-pump-type, hot-air generator () for circulating a stream of hot air inside the drying tub (); the hot air generator () also having a tank () containing a predetermined amount of water, heating means for converting the water in the tank () to steam, and an exhaust manifold () for feeding the steam produced in the tank () to the drying tub (); the heating means being defined by at least one portion () of the pipe () feeding refrigerant from the compressor () to the condenser ().

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

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.
