Definitions

  • the present invention relates to a clothes dryer, particularly of domestic type with a rotatable drum and an open air circulating circuit, having an improved air suction and discharge device.
  • a first scope 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.
  • an air suction and discharge device for a clothes dryer particularly of domestic type, having a rotatable drum and an open air circulating circuit
  • said dryer having a fan and conduits for the air circulation, characterized in that it comprises a first structural element at least partially forming the rear wall of the dryer, and a second structural element which, in use, is snap-action coupled together with said first element in order to provide an inlet portion of the suction conduit and an end portion of the discharge conduit, said first element being provided with at least one air inlet whose upper edge is able to cooperate with a baffle integral with said second element in order to provide a labyrinth inlet path for the air sucked from the outside of the dryer.
  • said device substantial ly 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 pro perly 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 projec ting toward the interior of the dryer.
  • the plate portion 3 has a rectangularly shaped body (Fig. 2), the upper part 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 upper edge of the inlet 6 projects toward 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 be easily 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 provide.d, 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 discharging 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 a 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 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.
