Definitions

  • the present invention relates to a clothes drier, particularly of domestic type with a rotatable drum and an open air circulating circuit, having an improved air suction and discharge device.
  • Air may be discharged outside from the apparatus into the room wherein the dryer is located, if there are good ventilating conditions, or it is discharged outside the room through a flexible conduit connected to the dryer and passing through a hood or a wall, in order to avoid condensation of moisture inside the room.
  • known dryers for example from the US Patent No. 3.006.422
  • an air suction and discharge device comprising several conduits which need couplings not ensuring good air-tight connections.
  • said couplings are mounted inside the dryer and are accessible only after disassembling of at least one wall of the dryer (i.e. US Patents US-A--2.675.628 and US-A-3.892.048); therefore, servicing is difficult and involves undesirable long and costly operation.
  • a first purpose of the present invention is to provide an air suction and discharge device forming an open circuit and made by a reduced number of components.
  • a further scope of the invention is to provide a device of the kind mentioned above having a structure which prevents water sprinkles from entering the dryer, said device being easy to assemble and disassemble in order to allow a more convenient and quick servicing.
  • the problem is solved by an air suction and discharge device for a domestic tumble dryer, having a rotatable drum, heating means and a fan adapted to be connected in an open air-circulating circuit, said device being characterized by:
  • Fig. 1 diagrammatically shows a partially sectioned side view of a dryer provided with the device in accordance with the invention
  • Fig. 2 diagrammatically shows a rear view of the dryer of Fig. 1
  • Fig. 3 shows the device in accordance with the invention sectioned along line III-III of Fig. 2.
  • a domestic clothes dryer with a rotatable drum and an open air circulating circuit is shown.
  • the improved air suction and discharge device according to the invention.
  • said device substantially comprises an outer structural element 1, which forms at least a part of the rear wall of the dryer, and an inner structural element 2.
  • Said outer and inner elements are able to be snap-action coupled longitudinally in order to provide an end portion of the discharge circuit for the moisture and an inlet portion of the suction conduit for the fresh air.
  • each element 1 and 2 has a properly shaped, single-piece structure and the unit formed by the snap-action coupling of said elements performs the air suction and discharge functions into and from the dryer.
  • the outer element 1 has a plate portion 3 and a conduit portion comprising two walls 4, 5 projecting toward the interior of the dryer.
  • the plate portion 3 has a rectangularly shaped body (Fig. 2), the upper of which is provided with at least an air inlet 6, whereas the lower part is provided with a circular outlet 7 for discharging the moisture.
  • the cross section of the plate portion 3 (Fig. 1) is rectilinear in the lower portion of the inlet 6 and has a stepped profile in the upper portion of the same.
  • the upper edge of the inlet 6 projects towards the interior of the dryer.
  • the walls 4, 5 of the element 1 are located below the inlet 6 and define, together with the portion of the plate 3 between said walls, a portion of conduit having a U-shaped cross section.
  • the inner element 2 similarly to the outer element 1, shows two different portions, i.e. a lower shell 9 with a semicircular cross section and an upper baffle 10 integral with the shell 9 and protruding upwards from its upper edge.
  • the baffle 10 is substantially vertical and its free edge 11 is bent toward the rear wall of the dryer.
  • conduit portion defined by the walls 4, 5 of the outer element 1 and the shell 9 of the inner element 2 can easily be coupled to each other by means of snap-action fasteners 12 integral with and placed along the connection edges of the elements (Fig. 1 shows only fasteners 12 on the lower edges).
  • Fig. 3 shows the so shaped discharge conduit which is extending horizontally and is provided, besides the outlet 7 in the outer element 1, with two further outlets 13, 14 located at its opposite ends.
  • the outlet 13 is a lateral opening for discharge ing the moisture, while the mouth of the outlet 14 is substantially 45° oriented to form a releasable connection, with the interposition of a sealing ring 15, together with a corresponding opening 16 of a two-way fitting 17 which is fastened by screw means (not shown) to the rear wall of the dryer.
  • the two-way fitting 17 has an outlet 18 on one side and an opening 19 on another side for the connection to the delivery conduit 20 of a fan 21.
  • connection of elements 1 and 2 allows also to obtain, above the discharge conduit, said labyrinth inlet path, which is defined by the upper edge of the inlet 6 and the baffle 10 having the bent edge 11.
  • the outer element 1 also forms at least a part of the rear wall of the dryer and is secured to said wall by means of screw means 22.
  • the dryer is provided with an suction opening 6 and three discharge outlets 7, 13, 18, respectively, which are positioned on two sides and on the rear wall of the apparatus to allow the discharge of the moisture in the most favorable direction with respect to the positioning of the dryer in the room.
  • the discharge outlets which are possibly not utilized are provided with closing caps (known per se and not shown), while the outlet selected for the discharge of moisture is connected by means of a bush with a flexible discharge conduit, which conveys the moisture outside the room.
  • the closing caps and connecting bush may be connected to the corresponding outlets by means of snap-action couplings similar to those which are used to join elements 1 and 2.
  • connection between the opening 14 of the discharge conduit and the opening 16 of the two-way fitting 17 can be easily released by traction in order to remove the device from the dryer.
  • Elements 1 and 2 can be easily disaccoupled, by loosening the snap-action fastener 12, and it is ensured the possibility to inspect the interior of the suction and discharge conduits.
  • air is sucked through the opening 6, flows along the suction conduit, is heated by electrical resistances 23, enters the drum 24, from which moisture flows out which flows through the conduit 25, the fan 21 and the delivery conduit 20. Then, moisture reaches the discharge conduit and is discharged through one or more openings 7, 13, 18 depending on the choice of the user.
  • the inlet portion of the suction conduit forms a labyrinth path defined by the upper edge of the opening 6 and the bent edge 11 of the baffle 10; this labyrinth path prevents possible leakages due to water sprinklings from the room into the dryer so as to fulfil the security standards.
