Definitions

  • the present invention refers to a top-loading clothes washing machine of the kind provided with an improved top closing lid.
  • top-loading clothes washing machine of a single-duty type i.e. designed to only wash and spin-dry clothes
  • a combined clothes washing and drying machine i.e. a so-called washer-drier
  • Top-loading clothes washing machines are generally known in the art to be provided with a top or upper lid of an essentially traditional kind, in which said lid is usually made in a sandwich-like manner with a top surface generally made of sheet-steel extending on a horizontal plane, and a corresponding lower surface, or counter-lid, made of plastics and facing towards the interior of the machine, i.e. towards the upper opening of the drum-holding tub.
  • a funnel-shaped member forming practically a hopper, which is substantially intended to act as both a guiding member and a safety means.
  • such a hopper-like member is designed to prevent the clothes being loaded in the drum from inadvertently slipping outside the upper loading aperture, while being guided to obligatorily fall through said loading aperture into the drum; in fact, along the upper portion thereof said hopper, along the upper portion thereof, is joined in a continuous manner with the upper edge of the outer casing of the washing machine, so that it is practically impossible for clothes to be placed on the machine, upon of course the lid thereof having been raised, without these clothes being spontaneously directed into the drum.
  • such a hopper prevents a user from being able to gain access into the interior of the machine from above, thereby avoiding easily imaginable risks and dangerous situations.
  • FIG. 1 is a perspective view of the lower surface of an upwards facing counter-lid
  • FIG. 2 which is a schematical, cross-sectional view of a portion of the counter-lid illustrated in FIG. 1 as viewed along the A-A sectional plane.
  • FIG. 3 is a symbolical perspective top view of the upper portion of a top-loading clothes washing machine with its lid in a partially open state;
  • FIG. 3A is a perspective view of the lower surface of the lid illustrated in FIG. 3 , as shown in the state in which it faces upwards;
  • FIG. 4 is a cross-sectional view along the sectional plane Z-Z of FIG. 3A of a portion of a counter-lid according to the present invention
  • FIG. 5 is a cross-sectional view similar to the one appearing in FIG. 4 of a further improved embodiment of a counter-lid according to the present invention.
  • FIGS. 6 and 7 are cross-sectional views of two further improved embodiments of a counter-lid according to the present invention, respectively;
  • FIG. 8 is a symbolical view similar of a further improved embodiment of a gasket member of a counter-lid according to the present invention.
  • FIG. 9 is a view corresponding to the one appearing in FIG. 3 of a different embodiment of a top-loading clothes washing machine, as shown with its lid in a partially open state.
  • a washing tub 1 in which there is rotatably supported the inner drum holding the clothes to be washed, an upper lid 2 enabling access to the interior of the inner drum to be gained from above, an outer casing 3 , a hopper 4 which is located above the upper aperture of the tub 1 and joins with its upper portion with the outer upper edge 5 of the outer casing 3 , an upper lid 6 provided with a lower counter-lid 7 .
  • a groove 9 extending in a closed-loop pattern therearound to substantially surround the loading aperture of said hopper 4 when the lid 6 is closed.
  • this groove 9 there is formed a gasket 10 of a suitable thermoplastic, elastic material, wherein said gasket does not only fill up said groove, but also protrudes outwardly therefrom all along the extension thereof; therefore, when the lid is lowered into closing, said gasket protrudes downwards, so that the resulting outward protrusion 11 comes to arrange itself in the form of a closed-loop ring elastically separating said counter-lid, and the related lid, from said hopper.
  • the resulting separation is a continuous one extending evenly all along the closed loop formed by the groove 9 with a constant cross-section.
  • This feature also enables a steam-tight sealing effect to be obtained between the inside of the hopper and the outer ambient, when the lid is closed, since the lid carrying said sealing gasket means is in this manner capable of actually working as a “stopper” plugging said hopper.
  • the above-mentioned overinjection moulding operation can be further optimised through a moulding sequence in which there is first moulded, eg. injection moulded, the counter-lid and said gasket is then overinjected onto the thus formed counter-lid immediately thereafter, i.e. before allowing the counter-lid to cool down excessively.
  • first moulded eg. injection moulded
  • the counter-lid and said gasket is then overinjected onto the thus formed counter-lid immediately thereafter, i.e. before allowing the counter-lid to cool down excessively.
  • a first improvement lies in the possibility for the portion of said annular gasket 11 protruding from said groove to be subdivided into two distinct lips 11 A and 11 B, as this is shown schematically in FIG. 6 , where it can be noticed that these two lips are oriented inwards and outwards, respectively, relative to the gasket itself, so that, further to improving the elastic dampening effect, they prevent air or foreign bodies from passing therethrough in either direction.
  • FIGS. 6 and 7 show respective cross-sectional views of the gasket with its respective lips 11 A and 11 B, in which FIG. 6 illustrates the cross-section profile of the gasket in correspondence of the side “ 11 A”, whereas FIG. 7 illustrates the cross-section profile of the gasket in correspondence of the side “ 11 B”. It should be noticed how, in the first case ( FIG. 6 ), said gasket has a height m that is lower than the height M of the same gasket on the side shown in FIG. 7 .
  • a further improvement is obtained by providing a material interruption or gap 12 in the profile of the portion of gasket protruding from the groove 9 , as this is symbolically illustrated in FIG. 8 .
  • This gap allows gas to pass therethrough from said hopper to the outside ambient when said lid is closed.
  • the above-mentioned gap is situated in the rear portion of the gasket, i.e. on the side of the gasket that is opposite to the one facing the user.
  • Such improvement enables a venting provision to be created for letting out air and steam forming inside the washing tub and generally seeping out from the lid of the machine, which must be exhausted outside without other internal parts of the machine being affected by it.
  • the portion of the gasket on the rear side of the lid to locate such gap, the resulting vent will not let out steam directly into the space where the user generally stands.
  • the hopper 4 does not join directly with the upper portion of the outer casing, but rather extends upwards until it joins up with a joining member 14 that seals and joins horizontally the upper edge of said hopper with the outer upper edge 5 of said outer casing 3 .
  • this gasket 10 along with all above-described improvements and embodiments thereof, refers to a similar or equivalent type of gasket, which however extends between said counter-lid and said joining member 14 .
