Definitions

  • the present invention relates to a laundry dryer provided with a rotatable drum adapted to be simply and reliably mounted therein.
  • conventional laundry dryers are provided with a rotatable drum adapted to contain the laundry to be dried and mounted in an exterior housing, said drum being traversed by a stream of drying air generated by at least one blower or fan and heated by means of suitable heater elements.
  • the drum itself is formed of a cylindrical side wall and two end walls, a front end wall and a rear end wall, respectively, both of which may be supported by the frame of the machine.
  • the rear end wall is provided with a central stub axle cooperating with a suitable support, e.g. a bushing or roller bearing carried by the frame of the machine, while the front end wall is formed with a projecting circular rim portion cooperating with a complementary circular support located in the forward portion of the housing.
  • a suitable support e.g. a bushing or roller bearing carried by the frame of the machine
  • the front end wall is formed with a projecting circular rim portion cooperating with a complementary circular support located in the forward portion of the housing.
  • the stub axle carried by the rear end wall is first introduced into its support and secured in position by means of conventional fastening means preventing the stub axle from being withdrawn from the support. Subsequently the projecting circular rim portion of the front end wall is inserted over the above defined circular support which to this effect is provided with slide elements of a suitable low-friction material, with the interposition of a seal formed of felt or another low-friction material for preventing the escape to the exterior of the heated air circulating in the drum.
  • the drum is freely rotatable without the possibility of axial displacement.
  • the drum can be dismounted after releasing the described fastener elementsat the rear of the housing of the machine.
  • a laundry dryer having a rotatable drum adapted to be dismounted in a simple manner by operating solely from the forward portion of the machine.
  • the drum is also in this case supported in the housing of the machine at its front and rear end walls without the possibility of axial displacement during rotation.
  • a laundry dryer of this type is characterized in that said central stub axle is supported in said rear support in a freely slidable manner in the axial direction, and in that said forward support element is provided with resiliently movable means adapted to exert an axial compressive force on said drum so as to constantly keep said axle stub engaged with said rear support and to prevent axial displacement of said drum.
  • the laundry dryer according to the invention substantially comprises an outer housing 3 and a drum 4 adapted to contain the laundry to be dried and to be rotated about its horizontal axis by means of an electric motor (not shown).
  • Drum 4 is formed of a cylindrical side wall 5 and two end walls 6 and 7, a rear end wall and a front end wall, respectively, adapted to support said drum within said housing in a manner to be described.
  • the rear portion of housing 3 is formed by a rear wall 8 formed with air inlet openings 9 for the aspiration of air which is conveyed to the interior of drum 4 through an inlet duct 10 communicating with the interior of drum 4 through perforations in rear end wall 6 and containing at least one electric heater element 11.
  • the dryer further vomprises a front opening 12 closed by a door 13 giving access to the interior of drum 4 and provided with a perforated interior wall 14.
  • Conduit 16 is further provided with a conventional filter 18 inserted into a conduit inlet opening 19 and adapted to retain nay lint released by the laundry and other foreign materials possibly entrained by the air stream.
  • Rear end wall 6 of drum 4 is provided with a central axle stub 20 formed integrally therewith or rigidly attached thereto, said axle stub being adapted to by axialle inserted into a conventional support 21 provided for instance with a bushing 22 of a low-friction material disposed in a suitable seat 23 formed in the rear wall 8 of the machine.
  • an elastic seal 24 of a low-friction material is disposed between rear end wall 6 and the housing of the machine for preventing the escape of heated air from the interior of drum 4.
  • the front end wall 7 of drum 4 is formed with a projecting circular rim portion 25 dimensioned for insertion over a circular support element 26 attached to a front wall 27 of the housing opposite front end wall 7 of drum 4.
  • support element 26 is formed of a circular array of individual support members each comprising a "C" profile section 28, an inclined web section 29 and an inverted “C” profile section 30.
  • slide elements 31 Located between a flat portion of first "C" profile section 28 and circular rim portion 25 of drum 4 are slide elements 31 formed of a low-friction material for sliding contact with circular rim portion 25 during rotation of drum 4.
  • the inclined web portion 29 of support element 26 is provided with a resilient seal 33 itself supporting a felt ring 34 for sliding contact with circular rim portion 25.
  • the inverted "C" profile section 30 of support element 26 serves as a seat for a plurality of slidingly movable abutment members 35 uniformly spaced about the periphery thereof and each biased by an associated compression spring 36 into axial abutment with circular rim portion 25.
  • Each abutment member 35 is formed with a projection 37 adapted to engage a stop 38 formed in "C" profile section 30 for preventing the abutment member from excaping from its respective seat.
  • the abutment members are formed of a low-friction material and are kept in sliding contact with circular rim portion 25 of drum 4 during rotation thereof.
  • axle stub 20 of rear end wall 6 is not fixed in position as in conventional constructions, but is retained in support 21 in a freely movable manner.
  • support element 26 is mounted opposite front end wall 7 so that its abutment members 35 axially abut circular rim portion 25 of drum 4.
  • the abutment members 35 are biased by their respective springs 36 into abutment with the circular rim portion 25 so as to exert an axial compressive force on the drum for keeping axle stub 20 engaged with its support 21.
  • the operation of mounting the drum in the laundry dryer according to the invention is considerably facilitated by comparison to similar operations on existing laundry driers.
  • the drum can be readily dismounted for maintenance, repairs and the like by operating directly from in front of the machine after removal of the forward support element. This is of particular advantages in a case in which the laundry dryer is installed in a limited space, for instance as part of a furniture combination.
