  • the present invention refers to appliances for drying laundry, both for domestic and professional use. More particularly, the present invention relates to a de-fluff filter.
  • Drying and washing/drying laundry machines - which will be referred to simply as laundry machine in the following - typically comprise a casing substantially parallepiped-shaped.
  • the casing accommodates a laundry treating chamber, comprising a drum, generally rotatable, apt to contain the laundry to be dried, in the case of a washing/drying laundry machine, the drum is rotatably contained in a tub.
  • a front panel of the casing has a loading opening to access the treating chamber for loading/unloading the laundry, and a door is provided for closing the loading opening, particularly during the laundry machine operation.
  • the casing also accommodates the electrical, electronic, mechanical, and hydraulic components necessary for the operation of the laundry machine.
  • laundry-drying capable machines features an air circuit (comprising, for example, fans, air ducts, a moisture condensing unit, a heating unit, etc. ) adapted to heat air, blow it into the drum where it removes moisture from the laundry, suck out from the drum the moisturized air, de-moisturize the air and reiterate such actions thereby performing a laundry drying cycle.
  • an air circuit comprising, for example, fans, air ducts, a moisture condensing unit, a heating unit, etc.
  • the laundry under treatment typically loses lint particles or fluff.
  • the fluff is generally light and tiny, thus it can be brought out from the drum by the hot drying air flowing therein and then into the air circuit.

  • the guiding blades 363 are, preferably, designed in such a way to reach the bottom wall 303e of the filter box 303, when the lid 306 closes the top aperture 303t, thus substantially subdividing the hollow chamber 361 of the filter box 303 in sub-chambers, having preferably a sectional area that increases along the drying air flow direction path, in such a way to distribute substantially evenly the drying air flow inside the filter box 303, and a have a preferably curved shaped to provide the best fluid-dynamic behaviour for the drying air flow thus homogenously directing the drying air flow towards the filtering mesh 321 and avoiding localized fluff accumulations and consequent localized occlusions thereof.
  • the guiding blades 363 are designed in such a way to be aligned with the mullion elements 318b of the frame 318, thus avoiding to hinder the drying air flow passing through the de-fluff filter 218.
  • alternative guiding blades may be provided protruding from the bottom wall of the filter box instead from the lid.
  • the lid 306 comprises a couple of hinges 366, preferably protruding substantially at opposite ends of a front side of the lid 306 (i.e., corresponding to the front sidewall 303b of the filter box 303).
  • Each hinge 366 protrudes from the lid frame 357 transversally thereto and has a pin 366a in its turn protruding from the center of a flat portion 366b transversally thereto, with the flat portion 366b that is preferably substantially circular.

  • the de-fluff filter 218 is inserted into the filter housing 217 through the housing aperture 219 with the rear sidewall 303a of the filter box 303 first, and with the lid 306 in the closed position.
  • the engaging head 345 intercepts and engages the matching engaging element 410 formed in the right sidewall 217c of the filter housing 217.
  • the engaging head 345 remains substantially blocked in a position abutting the matching engaging element 410, while the de-fluff filter 218 is further inserted into the filter housing 217. Thanks to such an abutment, the biasing spring 348 is compressed (i.e., switches from an elongated condition to a shrunk condition accumulating potential energy).
  • the rail elements 339b and 312b maintain the engaging head 345 in correct position, i.e. preventing any torsion thereof due to the lateral abutment with the matching engaging element 410 combined with the increasing compression provided by the insertion of the de-fluff filter 218 into the filter housing 217.
  • the protruding frame 333 engages the gasket element 210a obtaining a substantially airtight fluid connection with the inlet opening 210 of the filter housing 217.
  • the nose element 351 engages with a lower border of a nose slot 420 formed in the base element 205 close to the aperture 219. The nose element 351 engaging the lower border of the nose slot 420 prevents the biasing element 348 of the ejection device 312 from extending back into the elongated condition, thus maintaining the de-fluff filter 218 in the inserted position inside the filter housing 217.
  • the de-fluff filter 218 can preferably be inserted in the filter housing 217 only if the tab 327 is inserted inside a tab slot 425 that is provided on the separating wall 205a of the base element 205, which substantially separates the control panel 130 from the inner portion of the top 125, preferably in a position close to the aperture 219.
  • a user can easily unlock the de-fluff filter 218 from its housing 217 simply by pressing the pushbutton portion 145 of the aesthetic cover 140 of the de-fluff filter 218.
  • the pushbutton portion 145 is provided with an appendage 435 (even though more appendages may be provided as well) that contacts the push portion 315a of the locking element 315. Therefore, by pushing the pushbutton portion 145 the pushing action is transferred to the push portion 315a, which causes the locking element 315 to pivot about the axis defined by its two pins 315c. This pivoting makes the sliding elements 351b intercept the lower border (i.e., the more external border) of the nose slot 420 with their inclined edges deforming in a non-permanent manner the nose portion 315b.
  • Such deformation disengages the blocking element 351a of the nose element 351 from the nose slot 420, which in its turns allows the biasing element 348 of the pushing element 342 to extend in the elongated condition (thus releasing the stored potential energy as a kinetic force).
  • the sliding of the de-fluff filter 218 out from the filter housing 217 is substantially rectilinear thanks to the rails 339b and 312b which prevents the lateral swaying of the de-fluff filter 218.
  • the de-fluff filter 218 according to the present invention is thus adapted to be easily positioned and removed inside its filter housing 217.
  • the ejection device 312, the locking device 315 and the tab 327 provide a simple and efficient arrangement that ensure a correct insertion in operating position of the de-fluff filter 218 inside the filter housing 217 (with substantially no air leakages inside the top 125). This ensures that the correct insertion of the de-fluff filter 218 completes the air-path for the drying air, since the de-fluff filter 218 forms a fundamental portion thereof.
  • the de-fluff filter 218 along with trapping the fluff carried by the drying air flow, particularly thanks to the guiding wall 354 and the blades 363, directs the drying air flow towards the moisture condensing unit 225 with a minimal generation of turbulences and with a homogeneous distribution thereof along the whole length of the transversal opened side 274d, thus improving the heat exchanging operation of the heat exchanger 225 and 230.
  • the ejection device 312 and the locking device 315 allow an effortless releasing of the de-fluff filter 218 for the user (it is just needed to push the pushbutton 145 and then manually complete the extraction of the de-fluff filter 218).
  • Such effortless releasing together with the transparent panes 360 and with the positioning of the de-fluff filter 218 within the top 125 of the laundry machine 100 greatly simplify the de-fluff filter 218 inspection and cleaning by a user lowering the chance of a clogging of the de-fluff filter 218 due to lack of maintenance and a consequent reduction of efficiency of the drying air circuit.

  • the filtering portion 510f and the grasping portion 510g are made in one piece of any suitable material, such as a resilient polymer.
  • the filtering portion 510f comprises a frame 515 that encircles at least one, but preferably a plurality of filtering meshes 520 separated by auxiliary mullion elements 525 (i.e., each auxiliary mullion element 525 divides two corresponding adjacent filtering meshes 520 between which the auxiliary mullion element 525 is provided).
  • the filtering meshes 520 are narrower (i.e., finer) than the filtering mesh 321 of the de-fluff filter 218 is, in order to trap small fluff particles escaped from the latter.
  • the auxiliary mullion elements 525 bestow an enhanced robustness to each one of the plurality filtering meshes 520 preventing deformation of the filtering meshes 520 that the air flow may provoke.
  • the grasping portion 510g is provided at one end of the auxiliary de-fluff filter 221 and comprises a grip portion 530 preferably adapted to be firmly gripped with only two fingers by a user, e.g. the grip portion 530 comprises a plurality of ribs 535 preferably formed transversal to a largest side of the auxiliary de-fluff filter 221 for enhancing a grip from the user.
  • the grasping portion 510g also comprises a finger hole 540 adapted to be hooked by a finger of a user in order to more easily extract the auxiliary de-fluff filter 221 from the top 125 of the laundry machine 100.
  • each elastic engagement element 545 substantially comprises a bump 545a protruding outwardly from the rim 550 of the auxiliary de-fluff filter 221 and an eyelet 545b just beneath the bump 545a.
  • the auxiliary de-fluff filter 221 can be easily made to slide into a path defined by housing grooves 505u and 505l by a user.
  • the auxiliary de-fluff filter 221 is inserted inside the top 125 through an auxiliary slot 555 positioned adjacent to (preferably between) the housing aperture 219 and the tab slot 425 in the front sidewall 205b of the base element 205, for example by a user holding the auxiliary de-fluff filter 221 by its grasping portion 510g.
  • the auxiliary slot 555 is positioned in such a way to be hidden by the cover element 140 when the de-fluff filter 218 is inserted in the filter housing 217.
  • the housing grooves 505u and 505l runs in the inner panel 235 and in the base element 205, respectively, parallel and opposite to each other (when the inner panel 235 covers the base element 205), and preferably adjacent to the frame 220 of the transversal opened side 217d of the filter housing 217.
  • a distance between the housing grooves 505u and 505l is designed to substantially correspond to the cross-sectional height of the auxiliary de-fluff filter 221, in such a way that the latter slidably fits the former (as can be appreciated in Figure 5B ).
  • the auxiliary de-fluff filter 221 is inserted inside the top 125 through the auxiliary slot 555 positioned adjacent to the housing aperture 219 until the bumps 545a trespass corresponding engagement portions (not shown) protruding from the housing grooves 505u and 505l in opposite positions (e.g., towards each other).
  • the bumps 545a of the two elastic engagement elements 545 are deformed, i.e. the bumps 545a bend inwards closing the respective eyelet 545b, thus the elastic engagement elements 545 trespass the engagement portions and the auxiliary de-fluff filter 221 reach a working position.
  • the bumps 545a may return in their normal (i.e., protruding) configuration abutting against the engagement portions, thus securing the auxiliary de-fluff filter 221 in its working position, i.e. completely inserted in the housing path defined by housing grooves 505u and 505l (even though embodiments of the present invention featuring bumps that remains compressed when the auxiliary de-fluff filter is in its working position are not excluded).
  • the auxiliary de-fluff filter 221 follows the bend defined by the housing grooves 505u and 505l (which substantially corresponds to a bend of the transversal opened side 217d, as can be appreciated in the exploded view of Figure 5C ) thanks to its resiliency.
  • a sidewall 560 of the auxiliary slot 555 preferably the sidewall separating the auxiliary slot 555 from the housing aperture 219, is provided with an aperture 560a extending towards the inside of the filter housing 217 from the auxiliary slot 555.
  • the aperture 560a allows the user easily and completely fitting the auxiliary de-fluff filter 221 in the path defined by housing grooves 505u and 505l, since the grasping portion 510g may be hold by the user (through the aperture 560a) until the auxiliary de-fluff filter 221 is brought in its working position.
  • the auxiliary de-fluff filter 221 is adapted to trap in its meshes 520 fluff that has possibly escaped from the de-fluff filter 217 in order to prevent such fluff from reaching the heat exchanging units 225 and 230.
  • the auxiliary de-fluff filter 221 provides an improved filtering capability to the air circuit by further reducing an amount of fluff able to reach the moisture condensing unit 225 and/or the air heating element 230, thus considerably lowering the possibility of malfunction or efficiency reduction connected to fluff dispersed in the air circuit of the laundry machine 100.
  • the position of the auxiliary de-fluff filter 221 allow a user to perform an inspection and a cleaning thereof contextually with the inspection and the cleaning of the de-fluff filter 218, while the strip-like shape of the auxiliary de-fluff filter 221 allows a cleaning as easy as possible thereof (e.g., it may be sufficient to rinse the auxiliary de-fluff filter with some water).
  • the laundry machine 100 may operate also without the auxiliary de-fluff filter 221 in its working position, i.e. with only the de-fluff filter 218 filtering the air flow coming from the laundry treatment chamber 105.
  • the auxiliary filter 221 and the housing grooves 505u and 505l may be omitted.
