Definitions

  • the present invention relates to a clothes drier comprising: a drain circuit with a terminal portion which defines a first longitudinal axis and is able to drain water inside an extractable container provided with an inlet which defines a second longitudinal axis, a seat able to receive the extractable container, and an engaging device able to ensure engagement of the terminal portion of the drain circuit with the inlet so as to transfer water from the drain circuit into the container when the container is located in its seat wherein the engaging device comprises at least one first member pivotably mounted on a pivot fixed with respect to the terminal portion of the drain circuit.
  • Such a clothes dryer is known, e.g. from EP 0 484 225 A .
  • EP 1 524 359 A discloses a clothes dryer comprising a drain circuit with a terminal portion which is able to discharge water inside an extractable container having an inlet, a seat able to receive the extractable container, an engaging device with at least one first member pivotably mounted on a pivot fixed with respect to the terminal portion of the drain circuit.
  • Clothes driers are electric household appliances which are particularly common in cold climates where it is not possible to hang out washing to dry. Since generally, in the premises where they are installed, all the water drain pipes are already used by the sanitary apparatus or by the washing machine, clothes driers are designed so that they do not require any type of connection to the water mains.
  • the water which is extracted from the damp clothes during drying is therefore collected, via a drain circuit inside the said clothes drier, in a special container.
  • the user is able to extract the container and empty it, for example in the bathroom or in the kitchen.
  • the drain circuit and the container are provided with respective safety valves, for example such as those shown in Figure 2 .
  • valves 100, 200 each comprise a central duct 101, 201, contained in a support 102, 202 which has openings 104, 204 for allowing the water to pass through in the vicinity of one end 103, 203.
  • the ends 103, 203 of the central ducts 101, 201 protrude from the associated support 102, 202 so as to connect the terminal portion 4 of the drain circuit to the container 2.
  • the terminal portion 4 of the drain circuit defines a first longitudinal axis X-X; the terminal section of the inlet 3 of the container 2 defines a second longitudinal axis Y-Y (visible in Figure 1 ).
  • a spring 105, 205 is arranged in each valve between the central duct 101, 201 and the support 102, 202 so that, when the container 2 is not in its seat, the valves 100, 200 assume the closed configuration again.
  • this object is achieved by means of a clothes drier according to Claim 1.
  • container 2 is provided with an inlet 3 which is substantially cylindrical and extends mainly along an axis Y-Y.
  • inlet 3 which is substantially cylindrical and extends mainly along an axis Y-Y.
  • the terminal portions of the drain circuit and of the inlet comprise each a safety valve, preferably such as those described above with reference to Figure 2 .
  • terminal portion of the drain circuit has to be understood also as meaning the parts which are immediately adjacent to the actual pipes.
  • An engaging device 5 ensures that the inlet 3 is correctly inserted and kept in position in terminal portion 4 of the drain circuit so as to prevent accidental leakage of water.
  • Inlet 3 comprises a pin 6 (not visible in Figure 1 ) which is able to slide inside suitable guides 7, 12.
  • Pin 6 is composed of a preferably cylindrical part projecting from the outer surface of the inlet, perpendicularly with respect thereto.
  • Terminal portion 4 of the drain circuit comprises a slot 7 able to guide inlet 3 along the axis X-X so as to form the sealed connection described above.
  • slot 7 is substantially equal to the diameter of pin 6 so as to engage with it without play; if necessary, opening 8 of slot 7 may be slightly diverging.
  • the slot is in the horizontal direction.
  • the engaging device 5 is a hinge-type articulated system, such as, for example, a toggle-joint system. It comprises at least a first member 9 pivotably mounted on a pivot P which is fixed with respect to the terminal portion 4 of the drain circuit.
  • the engaging device 5 may comprise resilient means 11 and a second member 10 which is hinged with first member 9 by means of a hinge H.
  • the first member is defined by two sides A and B which are substantially parallel to each other, two sides C and D which are inclined with respect to A and B and substantially parallel to each other, a slot 12 with sides parallel to A and B and two sides E and F.
  • Angle AC in the vicinity of pivot P, is obtuse, while acute angle BC is radiused close to hinge H.
  • Slot 12 which separates two arms 13, 14 from each other, has a width substantially equal to the diameter of pin 6 and a length such as to allow pin 6 to freely slide inside it during rotation of first member 9 about pivot P.
  • the side D defines, together with one of the sides of slot 12, the tip of arm 13; the tip of arm 14 is defined by sides E and F which are substantially symmetrical with respect to a plane parallel to sides A and B and passing substantially through the centre of arm 14.
  • the second member 9 has a substantially straight shape, having one end 15 hinged by means of hinge H with first member 9 and the opposite end 16 sliding, if necessary by means of a projecting engaging member (not shown), inside a guide 17 which is fixed with respect to the clothes drier 1.
  • the guide 17 allows the second end 16 of second member 10 to move along a (preferably straight) path and come into contact with resilient means 11, compressing them.
  • pin 6 is inserted at the same time into slot 7 and into the slot 12 formed, respectively, in terminal portion 4 of the drain circuit and in first member 9 of the engaging device 5.
  • the slot 12 is then rotated about the pivot P in clockwise direction, in the embodiment shown in the figures.
  • engaging device 5 The value of the force exerted by engaging device 5 on container 2 depends on the geometrical relationship between the parts; in the position shown in Figure 5 , engaging device 5 does not transmit any force to container 2.
  • resilient means 11 exert on first member 9 a torque which favours the insertion of container 2 inside its seat in the clothes drier 1.
  • pin 6 In order to pass from the configuration shown in Figure 4 (namely the one corresponding to initial contact between pin 6 and first member 9 of engaging device 5) to the one shown in Figure 5 , pin 6 (and therefore container 2) must perform a displacement along axis X-X which may advantageously be between 5 and 8 mm and preferably is equal to about 6.5 mm.
  • the displacement may instead be between 7 and 11 mm and preferably is equal to about 9 mm.
  • the force due to resilient means 11 which is transferred to container 2 by means of engaging device 5 is a resistance which decreases during the first stage of insertion (namely between the position shown in Figure 4 and that shown in Figure 5 ) and a positive force which increases during the second stage of insertion (namely between the position shown in Figure 5 and that shown in Figure 6 ).
  • Resilient means 11 may be a flexible spring, but also other constructional forms are possible such as, for example, a coil spring, a helical spring, a leaf spring, etc.
  • engaging device 5 has been shown as rotating in the clockwise direction during insertion, but could be designed symmetrically, achieving the same results.
  • inlet 3 has two diametrically opposite pins 6 which are inserted in two respective slots 7 formed on terminal part 4 of the drain circuit
  • the same effects of the present invention may be obtained by providing the clothes drier with a second engaging device symmetrical with the first device relative to a plane parallel to the plane defined by first member 9 and passing along the axis X-X.
  • the present invention has been described with reference to the axis X-X which, according to a preferred embodiment of the present invention, is horizontal. It is nevertheless possible to realise the teachings of the present invention even if the axis X-X should be oriented differently. Likewise, the present invention is applicable both to front loading clothes driers and to other types of clothes drier, such as, for example, top loading driers.
