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 the clothes and other items comprising, inside an outer casing with a worktop and a front panel, 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 saturated air from the drier, and filtering means adapted to retain the impurities carried by the air before said air flows into the drum, said filtering means are associated to a drawer arranged in a removable way in an air intake conduit for taking in drying air from the outside of said outer casing and extending below the worktop in correspondence to the upper part of the appliance.
  • DE 195 42 597 discloses an air-exhaust type laundry drier comprising an suction duct located on the lower portion of the appliance and provided with filtering means for the drying air, and a blow duct for exhausting the moisture-laden air leaving the drum.
  • the filtering means include a filter mat fitted to the suction duct inlet provided on the front wall of the appliance outer casing below the loading door. The filter mat is arranged behind a grating, which closes the suction duct.
  • US 5 822 883 refers to a clothes dryer dedicated to drying garments to be worn in clean room environments wherein the inlet air to the clean room is extensively filtered.
  • the clothes dryer provides a tumble dryer comprising an enclosure having a rotatable drum for receiving and tumbling garments, a fan and motor assembly for providing airflow through the drum, an exhaust duct near the drum, a particle counter assembly having a sampling tube in the exhaust duct, the particle counter for measuring the concentration of particles in the sample, and a unit for producing an output signal indicating the concentration of particles in the sample.
  • GB 2 262 595 discloses a laundry washing and drying machine, comprising means to realise the washing, including a washing agent distributor, and means to realise the drying by way circulating hot air, including a filtering element for said hot air.
  • the filtering element of the air arranged in the drying circuit of the closed type, is integrated in the washing agent distributor.
  • US 2 644 246 relates to a clothes dryer of the domestic air circulating type provided with a lint trap for the discharge outlet in which a primary lint collecting screen is pivotally mounted at opposite sides of an outlet duct, so that when considerable lint has accumulated on the screen, the lint screen offers sufficient resistance to the passage of air through the outlet duct that is tilted forward to a substantially horizontal position, in which position the accumulated lint will be blown off its surface.
  • DE 91 04 967 U refers to an air-exhaust type laundry drier comprising a fan and motor assembly for drawing air from the outside of the appliance and into the drum where the saturated air is discharged through a filter which is a part of the loading door.
  • the fan is located in correspondence with the base of the appliance where the outer casing is provided, at the lower frontal part below the loading door, with a pocket or undercut including a filter device through which the drying air is taken in.
  • the filter device comprises a filter bag pull-out from the pocket by removing an fastening flange or frame integrally formed with the casing.
  • DE 44 22 602 discloses a drying chamber ventilation useful for energy-saving.
  • the process comprises measuring the air conditioning data of the chamber and the adjoining inner space.
  • a fan for the aeration or deaeration of the space is controlled in a way that results in optimum drying results.
  • Filtering means are provided for the drying air taken in from outside the chamber.
  • DE 41 25 138 relates to a clothes airing unit adapted to be installed into a cupboard incorporating a supply air and waste air cleaning facility.
  • the supply air and waste air are guided through carbon and dust filters for absorbing unpleasant smells.
  • the air current is produced by means of a ventilator.
  • 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.
