Washing/drying machine with a device for cleaning an air filter
The invention relates to a washing/drying machine equipped with a filter cleaning device for removing filaments released by laundry items during the washing/drying cycle. For this purpose, the cleaning device comprises nozzles that spray water onto the filtering walls, on the side thereof facing towards the drying tub.
1. A washing/drying machine comprising:
a washing/drying chamber;
a basket housed in said chamber for loading laundry to be treated;
an air circuit comprising an intake channel, a delivery channel and a fan arranged between the intake channel and the delivery channel, for circulating air taken in from the chamber, the intake channel having a cylindrical geometry forming an intake port in communication with an aperture formed in a back wall of the chamber;
a filter comprising:
a cage-like structure having a cylindrical geometry complimentary in shape to the intake port in the intake channel and configured to be inserted in the intake port;
a filtering wall arranged about the cylindrical geometry of the cage-like structure; and
a crown having a cylindrical structure comprising a plurality of water nozzles distributed about a periphery of the crown, the crown configured to connect to the cage-like structure for jetting water onto a side of the filter facing toward the chamber where filaments get depoisted during circulation of air in the air circuit;
the cage-like structure and the crown configured to be secured to the cylindrical geometry forming the intake port in the intake channel.
2. The washing/drying machine according to claim 1 , wherein water is jetted against the filtering wall tangential thereto.
3. The washing/drying machine according to claim 2 , further comprising a hydraulic circuit for supplying water to the plurality of water nozzles.
4. The washing/drying machine according to claim 3 , wherein the hydraulic circuit for recirculating water coming from the chamber and/or from the air circuit, to be supplied to the nozzles.
5. The washing/drying machine according to claim 1 , wherein the water nozzles are defined by a plurality of protrusions extending from and positioned around the periphery of the crown.
6. The washing/drying machine according to claim 1 , wherein the crown comprises one or more appendices extending from a base of the crown.
7. The washing/drying machine according to claim 6 , wherein the cage-like structure comprises at least one slot for engaging the one or more appendices of the crown.
