Definitions

  • the present invention relates to a method of assembling the drum of a laundry drier, to a drum for laundry drier, and to a laundry drier provided with such drum.
  • present front-loading, rotary-drum, laundry driers generally comprise a substantially parallelepiped-shaped outer box casing; a cylindrical hollow drum for housing the laundry to be dried, and which is housed in axially rotating manner inside the casing to rotate about its horizontally-oriented longitudinal axis, directly facing a laundry loading/unloading opening formed in the front face of the casing; a door hinged to the front face of the casing to rotate to and from a closing position in which the door rests completely against the casing to close the opening in the front face of the casing and seal the rotatable drum; and an electric motor assembly for rotating the drum about its longitudinal axis inside the casing.
  • Laundry driers of the above type are also provided with a hot-air supply circuit which is designed to circulate inside the rotatable drum a stream of hot air which flows through the rotatable drum and the laundry contained therein, so as to dry the laundry; and with an electronic control unit which controls the functions of the drier.
  • laundry driers In a laundry dryer a very important feature is the ability to appropriately measure the degree of dryness of the clothes in order to adjust the duration of the drying cycle accordingly.
  • some known laundry driers are generally provided with an electric circuit adapted to measure the residual moisture content in the clothes based on such parameter as the electric conductivity or resistance.
  • Such circuit provided to carry out these moisture measurements generally comprises an electrically conductive contact strip supported on the external surface of the annular cylindrical wall of the rotatable drum.
  • the contact strip is electrically insulated from the drum by an electrically non-conductive sheet bonded to the drum and interposed between the strip and the drum.
  • the strip itself is electrically connected to the internal region of the drum, i.e. the region where the clothes to be dried are placed, via the clothes rising ribs, or lifters, disposed on the internal surface of the cylindrical wall of the drum.
  • a scanning arm carrying a brush is mounted on the machine casing such that the brush is able to engage the conductive strip.
  • the brush itself is electrically connected to a control unit, which is also in contact with an electric terminal in electrical communication with the internal region of the drum.
  • a control unit which is also in contact with an electric terminal in electrical communication with the internal region of the drum.
  • EP 1 914 341 discloses a drying machine comprising an electric circuit for determining the resistance and/or conductivity of the laundry contained in a rotating drum, the electric circuit comprising at least one electrode adapted to contact the laundry, a conductive contact member electrically connected to the electrode and extending around an external annular surface of the drum, a sliding contact adapted to slide along the conductive contact member in constant galvanic connection therewith when the drum is rotating.
  • the conductive contact member and the electrode are electrically insulated from the drum, and a control unit that is electrically connected between the sliding contact and the drum, for measuring an electrical quantity depending on the residual moisture content in the laundry; an electrically insulating adhesive layer is provided between the external annular surface of the drum and the conductive contact member to secure the member to the drum.
  • the above mentioned contact strip consists in a strip of electrically conductive metal material which is winded onto the periphery of the drum like a belt, immediately above the electrically non-conductive sheet bonded to the drum, and which is permanently tighten onto the cylindrical wall of the drum via the mutual seam folding and/or clinching of the two ends of the strip on one another.
  • this solution has the drawback that the sliding brush, while crossing the joint between the two ends of the metal material strip, tends to momentarily detach from the slip ring (i.e. to make a small jump while crossing the joint) causing noise and the rapid erosion of the sliding brush; in fact the mutual seam folding and/or clinching of the two ends of the strip produces, in the joint area, a small step or wrinkle on the surface of the strip.
  • Aim of the present invention is therefore to provide a method for producing a drum for laundry driers which eliminates these drawbacks, and which additionally allows reducing the production costs of the drum.
  • a method of assembling the rotatable drum of a laundry drier in which the rotatable drum comprises a substantially cylindrical and hollow body and a slip ring fitted onto the body so as to be substantially coaxial to the longitudinal axis of the body; the method comprising:
  • the ring orients itself substantially coaxially to the longitudinal axis (L) of the hollow body of the rotatable drum.
  • the step of providing the sleeve on the outer cylindrical surface of the hollow body may comprise the step of winding and attaching to the outer cylindrical surface of the hollow body a strip of electrically-insulating and elastic material, so as to obtain the sleeve.
  • the step of providing the sleeve on the outer cylindrical surface of the hollow body may comprise the step of over injecting or foaming the sleeve onto the outer cylindrical surface of the hollow body.
  • the method may comprise the step of cylindrically bending a strip of electrically-conductive material, and of side-to-side fixing one another the two ends of the strip so as to form the electrically-conductive ring.
  • the two ends of the strip may be side-to-side fixed one another by welding; preferably the two ends of the strip may be side-to-side fixed one another by LASER-welding.
  • the sleeve is made of a polyolefin-matrix foam or of an EPDM Polyethylene foam.
  • the electrically-conductive ring is made of metal.
  • the electrically-conductive ring may be made of steel.
  • the substantially cylindrical sleeve has a tapered truncated-cone profile so to facilitate the force fitting of the electrically-conductive ring.
  • substantially cylindrical sleeve may be provided with stopping means adapted to engage the cylindrical ring during its fitting onto the sleeve, so as to facilitate its correct positioning onto the sleeve.
  • these stopping means comprise an annular rim protruding radially from the surface of the sleeve opposite to the outer cylindrical surface of the hollow body, and in proximity of a second circular side edge of the sleeve.
  • the invention concern also a rotatable drum for laundry driers comprising a substantially cylindrical and hollow body and a slip ring fitted onto this body so as to be coaxial to the longitudinal axis (L) of the body; the slip ring comprises:
  • the ring is force fitted onto the sleeve so as to extend substantially coaxially to the longitudinal axis (L) of the hollow body of the rotatable drum.
  • the electrically-insulating sleeve may be made of a polyolefin-matrix foam or of an EPDM Polyethylene foam.
  • the side edge of the sleeve may have a tapered, truncated-cone profile.

  • the electronic control unit 17 is configured so as to stop the drying process, i.e. the rotation of rotatable drum 3 and the circulation of hot air, when the laundry inside the rotatable drum 3 has reached a given degree of moisture (or, in other words, a given degree of dryness); preferably the degree of moisture of the laundry at which the drying process has to be interrupted may be set by a user via a control panel or user interface 18 located preferably, but not necessarily on the front face of the casing 2, advantageously above the laundry loading/unloading opening 2a.

  • the slip ring 20 of the rotatable drum 3 comprises a substantially cylindrical ring 24, preferably substantially flat, made of electrically conductive material, preferably a metal material or a rigid and low-friction conductive plastic material, which is force fitted onto a substantially cylindrical sleeve 25 of electrically insulating elastic material, for example a polymeric-material foam having an open- or closed-cell structure, which in turn is attached, for example glued/stuck, on the outer cylindrical surface 5b of the hollow body 5 of the rotatable drum 3.
  • electrically conductive material preferably a metal material or a rigid and low-friction conductive plastic material

  • the thickness of the electrically-insulating cylindrical sleeve 25 is lower than 10 millimeters and preferably, though not necessarily, ranges between 3 and 6 millimeters.
  • a first circular side edge 25a of the electrically-insulating cylindrical sleeve 25 has preferably, though not necessarily, a tapered truncated-cone profile, so to facilitate the force fitting of cylindrical flat ring 24 onto the sleeve 25.
  • the sleeve 25 is provided with stopping means adapted to engage the cylindrical ring 24 during its fitting onto the sleeve 25, so as to facilitate its correct positioning on the sleeve 25; for example, with reference to the enclosed Figures, these stopping means may comprise an annular rim 26 protruding radially from the surface of the sleeve 25 opposite to the outer cylindrical surface 5b of the hollow body 5, and in proximity of a second circular side edge 25b of the sleeve 25.
  • the tapered truncated-cone profile of the first circular side edge 25a of the sleeve 25 helps the fitting of the cylindrical ring 24 on the sleeve 25, while the annular rim 26 arrests the axial movement of the cylindrical ring 24 during the fitting procedure.
  • the electrically-conductive cylindrical ring 24 preferably, though not necessarily, comprises a strip, preferably, but not necessarily, of metal material (for example a strip of AISI steel), which, before being fitted to the drum 1, is cylindrically bended and afterwards side-to-side welded, preferably LASER-welded, at its two ends, so as to form a substantially perfectly cylindrical element; therefore, differently from the above described known metal material strips, the conductive cylindrical ring 24 according to the invention isn't provided with the joint area a step which causes the jump of the brushes 21 crossing the joint.
  • metal material for example a strip of AISI steel
  • the conductive cylindrical ring 24 may be obtained by the extrusion or the molding of a suitable conductive material, so as to obtain a continuous ring without any joint area on its lateral surface.
  • the ring 24 is associated to the sleeve 25 after the assembly/production of this ring 24 (i.e. in a condition in which the ring 24 is a closed circular ring).
  • the electrically-insulating cylindrical sleeve 25 preferably, though not necessarily, comprises a strip of electrically insulating polymeric-material foam having an open- or closed-cell structure, which is winded and at the same time attached, preferably glued/stucked, onto the outer cylindrical surface 5b of the substantially cylindrical, hollow body 5 of the rotatable drum 3, preferably by a suitable adhesive so as to form a substantially perfectly cylindrical sleeve 25.
  • the electrically-insulating polymeric-material foam is preferably, though not necessarily, a polyolefin-matrix foam, more preferably a Polyethylenic-matrix foam, or even more preferably an EPDM Polyethylene (acronym of ethylene propylene diene Monomer (M-class) Polyethylene) foam.
  • a polyolefin-matrix foam more preferably a Polyethylenic-matrix foam, or even more preferably an EPDM Polyethylene (acronym of ethylene propylene diene Monomer (M-class) Polyethylene) foam.
  • the polymeric-material foam may be an EPDM Polyethylene foam having a closed-cell structure and with a Compression set ranging between 3% and 10% and preferably, though not necessarily, equal to more or less 5%; a Tensile strength ranging between 2 and 5 Kg/cm2 (about 200-500 kPa) and preferably, though not necessarily, equal to more or less 3.5 Kg/cm2 (about 350 kPa); and a hardness ranging between 15 and 20 Shore.
  • EPDM Polyethylene foam having a closed-cell structure and with a Compression set ranging between 3% and 10% and preferably, though not necessarily, equal to more or less 5%; a Tensile strength ranging between 2 and 5 Kg/cm2 (about 200-500 kPa) and preferably, though not necessarily, equal to more or less 3.5 Kg/cm2 (about 350 kPa); and a hardness ranging between 15 and 20 Shore.
  • the cylindrical sleeve 25 may be advantageously over injected or foamed (i.e. applied as a foam which solidifies onto the outer cylindrical surface 5b) onto the outer cylindrical surface 5b of the substantially cylindrical hollow body 5.
  • the assembly of the slip ring 20 onto the substantially cylindrical, hollow body 5 of the rotatable drum 3 comprises the steps of providing, on the outer cylindrical surface 5b of the body 5, a substantially cylindrical sleeve 25 which is made of an electrically insulating and elastic material; this step may be carried out, for example, by winding a strip 25' of electrically-insulating material, for example a strip of EPDM Polyethylene foam, directly on the outer cylindrical surface 5b of the hollow body 5 of rotatable drum 3, while at the same time attaching (for example gluing/sticking) the strip 25' to the outer cylindrical surface 5b, preferably, but not necessarily, via a suitable adhesive, so as to form, on the hollow body 5, the cylindrical electrically-insulating and elastic outer sleeve 25.
  • electrically-insulating material for example a strip of EPDM Polyethylene foam
  • this step may be carried out by over-injecting of foaming the sleeve 25 directly on the outer cylindrical surface 5b of the body 5.
  • the assembly of the slip ring 20 onto the hollow body 5 comprises also the step of force fitting a substantially cylindrical ring 24 of electrically-conductive material onto the sleeve 25, so that the ring 24 substantially uniformly radially compresses the electrically-insulating sleeve 25; advantageously, during its force fitting onto the sleeve 25, the ring 24 orients itself substantially coaxial to the longitudinal axis L of the hollow body 5 of rotatable drum 3.
  • the force fitting step may start by positioning the ring 24 in front of the truncated-cone profiled first circular side edge 25a, and successively pushing the ring 24 in a direction substantially parallel to the longitudinal axis (L) of the hollow body 5 of the rotatable drum 2; the truncated-cone shape of the first circular side edge 25a facilitates the insertion of the ring 24 onto the sleeve 25.
  • the inner diameter D0 of the ring 24 approximates downwards the outer diameter of the electrically-insulating cylindrical sleeve 25, during the fitting of the ring 24 onto the sleeve 25 the latter is elastically radially compressed; in the example illustrated in the enclosed Figures, the pushing of the ring 24 is interrupted when the ring 24 engages the annular rim 26. Because of its elasticity, the sleeve 25 tends to expand radially towards the ring 24, generating a pressure on the ring 24 which contributes to keep it firm with respect to the sleeve 25 and to the hollow body 5.
  • the assembly of the rotatable drum 3 preferably, though not necessarily, also comprises the step of cylindrically bending a strip (not shown) of electrically-conductive material, preferably a strip of AISI steel, and of side-to-side welding one another, preferably by LASER-welding, the two ends of this strip so as to form the substantially cylindrical ring 24.
  • the assembly of the rotatable drum 1 advantageously comprises also the positioning of one or more surface electrodes 19 (supported or not by ribs or lifters 22) on the inner cylindrical surface 5a of the hollow body 5 and the electrical connection of these electrodes 19 to the slip ring 20.
  • slip ring 20 The advantages connected to the particular structure of slip ring 20 are large in number.
  • Laundry drier 1 is therefore much more silent than traditional rotary-drum home laundry driers.
  • assembly of slip ring 20 on hollow body 5 of rotatable drum 3 via force fitting is less expensive and slightly faster than the mutual seam folding and/or clinching of the two ends of the strip one another.
