1. A washing/drying machine comprising:
- a washing/drying chamber;
a basket for loading laundry to be treated and housed in the chamber;
a circuit for circulating air taken in from the chamber and then reintroduced therein; and
a filter comprising;
a side wall defining a width of the filter;
a filtering wall closing the width of the filter at a front of the side wall and arranged perpendicular to the side wall, the filtering wall having a surface area for filtering the air along the circulation circuit; and
a filter cleaning device comprising a support element provided within the side wall directly adjacent to the filtering wall, the support element comprising;
a first arm extending across the width of the filter along the filtering surface area; and
a second arm extending across the width of the filter along the filtering surface area, the second arm orthogonal to the first arm such that the first and second arms intersect along the filtering surface area and divide the filtering surface area into at least four quadrants;
wherein each arm has a plurality of nozzles directed at each of the at least four quadrants and oriented at a tangential angle to the filtering surface area and adapted to spray water tangentially onto the filtering surface area, such that water from the first arm sprays in a first direction onto the filtering surface area and water from the second arm sprays in a second direction onto a surface of the filtering surface area whereon filaments get deposited during the circulation of air in the circulation circuit.

Abstract
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 arranged in a spider-like pattern, which spray water onto the filtering wall, on the side thereof facing towards the drying tub.
