Definitions

  • the present invention relates to a machine for drying and / or washing clothes provided with a fluff filter.
  • Known tumble dryers or washer-dryers usually have a filter disposed in their drying air circuit to stop the laundry stuffing. This filter quickly clogs and prevents normal circulation of the drying air, which requires frequent cleaning of this filter in order to maintain constant drying efficiency and good performance of these devices.
  • a brush is mounted and applied against the surface of their filter to pick up the fluff of laundry as it is deposited on this filter, the brush being fixed for a rotating filter or mobile for a filter fixed.
  • the present invention aimed at avoiding these drawbacks makes it possible to produce an economic machine for drying and / or washing linen, provided with a fluff filter which requires neither cleaning nor evacuation of fluff.
  • a machine for drying and / or washing linen with a rotating drum and a stuffing filter is characterized in that it comprises a stuffing filter having meshes or holes allowing small particles of stuffing to pass through. of a predetermined size, and a projecting shape towards the interior of the drum favoring during drying of the linen, a continuous and voluntary contact with the linen in movement in this drum and causing a cleaning of its surface and a voluntary and repeated fragmentation in small particles by this linen in movement, of the flock of laundry retained by this filter.
  • a dryer 1 illustrated schematically in Figure 1 comprises a body 2 and a laundry drum 3 rotating about a horizontal axis 4.
  • the dryer 1 is provided with a door 5 opening upwards.
  • the laundry drum 3 having a cylindrical shape comprises in its wall an access door 6 and in a first end flange a perforated or perforated part serving as an inlet opening 7 for the drying air and in a second end flange an outlet opening 8 for the drying air.
  • the air intake duct 10 connects an air intake opening 12 giving into the atmosphere outside and the drying air inlet opening 7.
  • the outlet duct 11 connects the drying air outlet opening 8 and an air exhaust opening 14 to the outside of the dryer 1.
  • a fan 15 is mounted in the inlet duct 10 to draw air from the external atmosphere and force it to circulate through a heating device 17, mounted in this duct to bring it to a predetermined adjustable air temperature before introducing it through the perforated entry opening 7 into the rotating drum 3 to dry a moving laundry which is lifted and stirred. After removing part of the moisture from this cloth, the drying air charged with moisture is forced into the air outlet duct 11 to be discharged through the opening 14 to the outside.
  • the dryer or machine for drying and / or washing the laundry 1 comprises in the drum 3, at the drying air outlet opening 8, a filter 20 having mesh or holes allowing passage of small particles of linen stuffing of a predetermined size, a solid structure and a shape, projecting towards the inside of this drum 3, favoring (during drying of the linen) a continuous and voluntary contact with the linen moving in this drum thereby causing a cleaning of its surface and a voluntary and repeated fragmentation by this moving linen, of the flock and / or of the lint of linen retained by this filter, in small particles which can pass through the meshes or holes of this filter.
  • the filter 20 which is constantly cleaned by the linen in movement in the rotating drum 3 is constantly clean, allows a normal flow of drying air to pass regularly through the drum 3 and thus allows the dryer laundry 1 to obtain high drying efficiency and constant good yield.
  • the filter 20 having a solid structure needs neither support nor protective grid.
  • the dry laundry is removed from the dryer 1 with all the fluff and / or residual or unfragmented lint adhered to its surface under the effect of static electricity while the filter 20 constantly cleaned by the moving linen until the rotating drum 3 stops is clean.
  • the filter 20 projecting towards the inside of the drum 3 may have as its surface in contact with the moving laundry a surface chosen from plain, angular or bumps, convex, concave or flat, inclined or perpendicular to the axis of rotation of this drum.
  • a dryer 25 illustrated in FIG. 2 comprises a body 26 provided with a front door 27, a horizontal drum rotating with laundry 28 provided in its front end flange with an opening access 30, in the border of this access opening, of a perforated crown or provided with perforations serving as an opening for drying air inlet 31 and in its rear end flange, with an outlet opening of drying air 32, an air intake duct 34 connecting an air intake opening 35 giving into the external atmosphere and the perforated crown of the drum 3 serving as an opening for drying air inlet 31, a drying air outlet duct 38 connecting a discharge opening 39 and the drying air outlet opening 32, and a fan 40 sucking in the outside air, forcing it to circulate through a device heater 41 to bring it to a predetermined temperature adjustable d drying air before introducing it into the rotating drum 28 to dry the moving laundry, which is lifted and stirred. After removing part of the moisture from this laundry to be dried, the drying air is forced outside through the air outlet opening 39 and the air outlet duct 38.
  • a filter 42 is mounted in the drum 28 at the drying air outlet opening 39.
  • This filter 42 has a structure similar to that of the filter 20 of the first example illustrated in FIG. 1.
  • the filter 42 comprises meshes or holes allowing small particles of linen stuffing of a predetermined size to pass, and a protruding shape towards the inside of the drum 3 promoting continuous and voluntary contact with the linen moving in this drum, causing a cleaning of its surface and a voluntary and repeated fragmentation of the flock and / or lint of linen into small particles which can pass through the meshes or holes of this filter 42.
  • the operation of the dryer 25 is similar to that of the dryer 1 of the first example. At the end of a drying operation, the dry laundry is taken out of the dryer 25 with all the residual fluff adhered to its surface under the effect of static electricity and the filter 42 is clean. No special removal of laundry fluff at the filter 42 or in the drum 28 takes place.
  • the fluff filters 20 and 42 are mounted non-removable on a corresponding end flange of the drums 3 and 28.
  • the fluff filters 20 and 42 thus rotate with the drums 3 and 28 in rotation.
  • the fluff filters 20 and 42 are fixed to a corresponding bearing support shaft of the rotating drums 3 and 28.
  • the fluff filters 20 and 42 remain, in this case, fixed during the rotation of the drums 3 and 28.
