Definitions

  • the present invention refers to a tumble drier for clothes and other items, in particular an exhaust-type tumble drier.
  • a tumble drier comprises a substantially parallelepiped outer casing in which there is enclosed a drum that, driven by an electric motor via a driving belt, is adapted to rotate according to a more or less horizontal axis.
  • the items to be dried are loaded in the drum through a door mounted on the front wall or the top wall of said outer casing.
  • a fan located inside the outer casing, takes in fresh air from the room in which the appliance is installed and forces it into the drum after it has been duly heated up by electric heating means or gas burners that are also provided inside the outer casing of the appliance.
  • the hot air is forced to flow through the interior of the drum, becomes saturated with the humidity it subtracts from the items loaded in the drum, which are in this way progressively dried, and is finally exhausted from the appliance.
  • the airborne impurities that are present in the installation room are taken in into the appliance along with the drying air.
  • the air intake occurs through apertures provided in the lower portion of the outer casing, eg. through the rear wall, the base of the appliance or even the zone below the loading door when the latter is attached to the front wall, further to such contaminants as cigarette smoke, odours generated during cooking (if the appliance is installed in a kitchen) or even possible airborne germs, ie. germs that can be transmitted by air, particularly significant, among airborne impurities in general, are the dust rolls or clots that form on the floor. In all cases, such impurities eventually come into contact with the items loaded in the drum for drying, and this of course has clear negative effects, in particular if such items are constituted by clothes made of silk, sponge cloth or similar fabrics.
  • a tumble drier for clothes and other items comprising, inside an outer casing, a rotating drum adapted to be loaded with the items to be dried, heating means as well as means capable of ensuring a forced circulation of air through the drum, means for exhausting the air from the drier after that, inside the drum, it has saturated with the humidity subtracted from the drying items, wherein along the flow-path between the air intake zone of the appliance and the zone at which said air then flows into the drum there are provided means adapted to retain the impurities carried by the air or present in the air taken in from the room in which the appliance is installed.
  • the tumble drier illustrated in the above cited Figures comprises a substantially parallelepiped outer casing 1 with a worktop 2, a front panel 3 carrying the control organs 4, 5.
  • a metal drum 6 Inside the outer casing 1 there is arranged a metal drum 6 that is adapted to be driven rotatably about a more or less horizontal axis X by an electric motor via a drive belt (for reasons of greater simplicity, these last items are not shown in the Figures).
  • the aperture of the front flange 7 of the drum 6 is capable of being closed by a rectangular door 8 that is hinged on to the front wall 9 of the outer casing 1.
  • the air is taken in from the room in which the drier is installed by a motor-driven fan (not shown in the Figures, but anyway arranged in the lower front zone of the outer casing 1) through an intake aperture 21 which is part of a pull-out drawer 20 that is accessible from the front panel 3.
  • the air is forced to flow through a first horizontal conduit 10 provided immediately below the worktop 2 and, in a sequence, an electric heating unit 11 and a second vertical conduit 12 provided therebelow. After having so been heated up, the air is then blown into the drum 6 through a plurality of perforations 13 provided in the rear flange 14 thereof.
  • the hot air leaves the drum 6 through an annular aperture which, duly provided with a lint filter, is located on the inside, ie. the liner of the door 8.
  • the moisture-laden, hot air is then conveyed through a third conduit (not shown, like the afore cited annular aperture and the lint filter)) up to a final aperture 15 located in the lowest portion of the left wall 16 of the outer casing 1.
  • a flexible hose (not shown, either) in order to definitively exhaust the air outside the building in which the drier is installed.
  • the box-like body of the drawer 20 sustains a frame 23 that is capable of swinging thanks to its being hinged along its lower edge.
  • the frame 23 sustains filtering means 22 for the drying air.
  • This construction is such as to ensure that, when the drawer 20 is pushed in, ie. closed, the frame 23 abuts against a flange 24 provided at the end of an initial portion 25 of said first conduit 10 and, as a result, the air taken in by the fan is capable to actually and effectively flow through the filtering means 22 which, in view of a greater efficiency and durability thereof, are provided in an inclined arrangement with respect to the air flow.
  • the filtering means 22 might also consist of a simple (and unexpensive) paper filter of the dust-bag type used in vacuum cleaners, in a preferred embodiment of the present invention such filtering means 22 consist of a partition of a material (eg. a polypropylene electret) adapted to retain dust particles, associated to an activated-carbon mat adapted to absorb detrimental gaseous substances contained in the air.
  • a material eg. a polypropylene electret
  • said filtering means 22 can therefore be inspected and, if needed, submitted to the required maintenance, ie. cleaning, regeneration and even replacement, even by the user him/herself (see Figure 2).
  • the drier may also be implemented in forms and with details differing from the above described and illustrated ones without departing from the scope of the present invention.
  • the drier can have its loading door attached to the top wall of the outer casing.
