Definitions

  • the present invention refers to a household laundry dryer, comprising a cabinet having a front wall and a rear wall, a generally cylindrical laundry drum rotatably mounted within the cabinet for rotating according to a substantially horizontal axis, support means for rotatably supporting the drum within the cabinet, driving means for rotating the drum, wherein the drum has a metal peripheral wall that is substantially cylindrical and extends between a front and a rear wall of the drum, the front and rear walls of the drum being substantially flange-shaped, each having at least one opening for passage of drying air and being fixed to a respective end edge of the peripheral wall.
  • Laundry dryers typically have a bearing structure or cabinet, through which a laundry drum is mounted, rotatable according to a substantially horizontal axis.
  • the drum is actuated through an electric motor, by means of a drive belt, and it is rotatably supported in the front and rear areas thereof by means of pairs of wheels or rollers.
  • the drum is supported at the front part thereof through an abovementioned pair of rollers and at the rear part by a shaft, coaxial with the rotational axis of the drum and associated to the rear wall thereof.
  • the machine has a circuit for conveying a flow of drying air, including a duct along which a fan and an electric resistance operate for heating the air.
  • the fan forces the air into the drum, by means of a delivery branch of the system, after the air itself has been heated by means of the resistance.
  • the hot air traverses the inside of the drum and is saturated with the moisture transferred by the laundry items contained therein, which items are thus progressively dried.
  • the hot air is generally introduced into the drum through a central region of the rear wall thereof, which is provided with a plurality of holes.
  • This region of the drum faces a region of the rear wall of the cabinet, also provided with one or more holes.
  • the duct which conveys the heated air downstream of the fan usually includes an end component which, together with the abovementioned region of the rear wall of the cabinet, forms a chamber, generally approximately circular shaped, so as to surround a region for spreading the air: the drying air spreads within the abovementioned chamber and then penetrates into the drum, through the holes of the respective rear wall.
  • Seal means usually made up of a low friction annular gasket, are operatively provided between the abovementioned regions provided with holes of the rear wall of the drum and the cabinet, so as to prevent the dispersion of the flow of hot air within the cabinet.
  • the front opening of the drum is in fluid communication with the suction branch of the drying air circuit, upstream of the fan, along which there is a condenser suitable for removing moisture from the air suctioned from the drum, such dehumidified air then being heated again and reintroduced into the drum by means of the delivery branch of the circuit.
  • the air exiting from the front opening of the drum is directed towards the external environment, directly through the door or through a respective discharge duct; as a matter of fact, in these machines the system for conveying the air is prearranged in such a manner that the fan suctions fresh air coming from inside the machine and/or from the installation environment thereof, and forces the air into the drum, after the respective heating, with the moist air exiting from the drum which is directly discharged from the apparatus.
  • the drum In laundry dryers the drum is conventionally made using metal sheets, usually made of stainless steel.
  • the drum In a type of machine, to which the present invention refers, the drum has an imperforate peripheral wall, substantially cylindrical, as well as a front wall and a rear wall which are flange-shaped.
  • the drum practically consists of the cylindrical wall alone: with the aim of preventing dispersions of the drying air and the moist air, these machines require gaskets of large diameter at the front and rear ends of the cylindrical wall, such gaskets being more subjected to wear and generating considerable frictions during the rotation of the drum, hence entailing complications in the actuation system.
  • the front and rear walls of the drum are configured as separate pieces with respect to the peripheral wall, and rigidly fixed thereto, by welding or clinching.
  • the front and rear walls are instead made integral with the peripheral wall.
  • the front and rear wall are obtained by means of blanking and deforming a respective sheet-metal.
  • the fact that the front wall must be provided with an opening sufficiently large to allow loading and unloading the laundry determines a waste of high amounts of material.
  • an additional closing component provided with a series of holes for passage of air, is usually fixed to the rear wall of the drum; in other solutions, an additional component, cylindrical-shaped, protruding towards the inside of the cabinet and coupled - with interposition of sealing means - to the opening of the rear wall of the drum, is fixed to the rear wall of the cabinet; in order to guarantee the passage of the drying air, such additional component is provided with one or more openings.
  • the present invention substantially aims at overcoming one or more of the abovementioned drawbacks of the prior art, in a simple and inexpensive manner.
  • a laundry dryer of the type indicated at the beginning of the present description is characterized in that at least one of the front wall and the rear wall of the drum has a main body made of plastic material, which is fixed at a respective end edge of the peripheral wall.
  • At least one end wall of the drum may be obtained in a simple and inexpensive manner, particularly through operations of injection moulding of plastic material, such as thermoplastic material.
  • plastic material such as thermoplastic material.
  • the solution allows avoiding typical wastes and swarf and simplifying the operations for the production of the drum, using relatively simple machinery.
  • the fact that the front and/or rear walls of the drum are made of plastic also offers the advantage of considerable flexibility in the choice of the shape or profile to be conferred to the walls in question, such profile being optimised according to the interaction thereof with other components of the machine, and not vice versa as it occurs in the prior art.
  • the end wall/s of the drum in such a manner to position and configure the surfaces intended to cooperate with the support rollers of the drum, or even the areas intended to cooperate with, or receive, the sealing means intended to prevent the dispersions of the airflows relatively at will.
  • the body of the front and/or rear wall of the drum is provided with a central opening and is shaped to have a generally cylindrical central portion, coaxial with the rotation axis of the drum and spaced from the opening, such cylindrical portion defining a supporting surface cooperating with respective support means of the drum.
  • the front and rear walls of the drum each have the respective main body made of plastic material.
  • the main bodies of the two walls are identical to each other.
  • the main bodies of the two end walls of the drum each have a central opening, substantially coaxial to the rotational axis of the drum.
  • the opening of the rear wall may be closed - even when the two end walls have different shapes - using an additional component, fixed to the same wall, with interposition of sealing means.
  • This additional element which may be made of metal material or also of plastic material, is provided with at least one hole for passage of the drying air.
  • the rear wall of the drum has a central cavity which receives a generally cylindrical element, inserted coaxial to the opening and inserted thereinto, which is in a fixed position with respect to the rear wall of the cabinet.
  • This protruding element may be made up of a body fixed to the rear wall of the cabinet or, in a particularly advantageous embodiment, directly formed by a drawing of the rear wall of the cabinet.
  • the abovementioned drawing is substantially blind, or is made up of a cylindrical wall and a bottom wall, and at least one hole for passage of the drying air is formed in the latter.
  • the abovementioned drawing overcomes the need for application of additional components to the rear wall of the cabinet, hence leading to the further advantage of reduction of costs required for the production of the machine.
  • the abovementioned central cavity may pass through the rear wall of the drum or be a cavity defined by a cylindrical wall and by a bottom, provided with one or more holes for passage of the drying air.
  • the main body of the front and/or rear wall of the drum is prearranged for coupling with the respective end edge of the peripheral wall.
  • the main body of the front and/or rear wall defines a seat for coupling with said end edge of the peripheral wall.
  • the abovementioned seat is obtained by means of two cylindrical walls, concentric with respect to each other and coaxial to the rotation axis of the drum, which define - with respect to each other - a space in which the corresponding end edge of the cylindrical wall of the drum is received.
  • the support means of the drum includes a shaft coaxial to the rotational axis and this shaft is associated to said rear wall.
  • a seat in the plastic body of the rear wall a seat may be easily defined by moulding, for housing a coupling member for the shaft, such as a hub or ball bearing or the like.
  • the plastic body of the wall may also be overmoulded on the abovementioned member.
  • the plastic wall may be directly moulded on the respective end of the shaft.
  • front wall or “rear wall” with reference to the drum, are used to indicate a component obtaining the structure or main body of a respective end wall of the drum, fixed to an end edge of the peripheral wall thereof, and without prejudice to the fact that other components, such as gaskets, sliding pads or a closing member, may be associated to such main structure, as described hereinafter.
  • plastic material and the like, are used to indicate any plastic or synthetic material, or based on plastic or synthetic material, possibly added with fillers suitable to improve the functional and robustness characteristics thereof, such as mineral, textile synthetic fillers and so on and so forth.

  • the drum 7 has a peripheral wall 13, generally cylindrical and made of metal material, for example stainless steel.
  • the drum 7 further comprises a front wall 14 and a rear wall 15, between which the peripheral wall 13, which is not perforated, extends.
  • the front and rear walls 14 and 15 of the drum 7 are generally flange-shaped and are fixed each to a respective end edge of the peripheral wall 13; such end edges are indicated only in figure 3 with 13a and 13b.
  • the front wall 14 and rear wall 15 each have at least one through hole.
  • At least one of the front wall 14 and the rear wall 15 of the drum 7 has a main body made of plastic material, which main body is fixed at the respective end edge 13a or 13b of the peripheral wall 13 of the drum 7.

  • a material useable for the purpose may be polypropylene, preferably filled with talc, for example at about 30% (other filler materials may for example be calcium carbonate or glass fibre).
  • Plastic or synthetic-based materials of this type are perfectly suitable for bearing the temperatures typical of the flow of the drying air present in a common laundry dryer.
  • the front 14 and rear 15 walls of the drum have the respective main bodies identically shaped with respect to each other. Therefore, in the illustrated example, the walls 14 and 15 are provided with respective central through openings, indicated with 14a and 15a, having a relatively wide diameter, coaxial to the rotational axis of the drum 7.

  • the air thus rises along the rear wall 4 of the cabinet, into the component 16, up to the top part thereof, in which a region for spreading the airflow is essentially defined.
  • the drying air thus penetrates into the drawing 17 and, through the respective holes 17c, it may penetrate towards the inside of the drum, due to the presence of the holes, not represented, of the covering element 18.

  • plastic material considerably simplifies the process of obtaining the front and rear walls or flange of the drum, also using comparatively less materials with respect to the stainless steel used conventionally. Also the plastic material moulding operations, particularly injection moulding, are simplified with respect to those of deforming sheets typical of the prior art. Also swarfs and wastes typical of the prior art solutions are clearly considerably reduced.
  • the invention also allows the big advantage of offering a wide range of choice of the profile to be conferred to the end wall/s of the drum, by means of a simple prearrangement of equipment (and in particular moulds) used for the plastic material moulding operations.
  • a big advantage of this solution idea lies in that, contrary to the prior art, the shape of the front and/or rear flange of the drum may be optimized depending on the type of positioning, dimensions and construction intended to be conferred to the components meant to cooperate with the flanges, and specifically the support means - whether represented by pairs of rollers or comprising a rotation shaft - and the means for sealing and/or conveying air provided for in the front and/or rear part of the cabinet of the machine.

  • the profiles of the two end walls of the drum may be different.
  • the cylindrical portion 14b could possibly be omitted, a simple through opening 14a - obtained in the radial wall portion 14c - being provided for in such case.
  • the front part of the drum there shall be provided means whose function shall be analogous to those indicated with 6a in figure 2 , or configured to allow the conveying of the drying air which exits from the front of the drum 7, to prevent dispersions of moist air into the cabinet of the machine and to prevent that - during the operations of loading and unloading textile items and during the rotation of the drum - portions of such textile items find their way out of the drum and/or slip between the drum and the fixed structure of the machine.
