Definitions

  • the present invention concerns a front-loading laundry washing machine.
  • Machines of the type indicated include a laundry basket mounted in a washing tub, itself housed in a cabinet.
  • the cabinet has a front-loading opening in correspondence to which a door is mounted, and this opening is substantially aligned with a front opening of the tub, which is in turn substantially aligned with a front opening of the basket.
  • the basket is mounted such that it can rotate around a substantially horizontal or slightly inclined axis, which is in a fixed position with respect to the tub.
  • the tub is flexibly suspended in the cabinet, to allow oscillations caused by the loads acting on the basket during its rotation, such loads being due to the weight of the laundry under treatment.
  • a substantially tubular gasket extends between the front wall of the tub and the front wall of the cabinet, defining a sealed passage.
  • the opening of the cabinet opens at one end of such passage, while the opening of the tub and that of the basket open at the other end.
  • the presence of the above said gasket (commonly called “diaphragm") prevents part of the washing liquid or of the laundry load from coming out from the tub and basket and slipping into the interspace that exists between the tub and the cabinet.
  • the gasket must allow for a certain relative movement between the cabinet and tub, since - as was said - the latter is subjected to oscillation during the rotation of the basket: for this reason the gasket, and therefore the tubular passage defined by it, must have a certain axial length and be elastic, preferably shaped, at least in part, like a bellows.
  • an inner or rear portion of the door extends into the tubular passage defined by the gasket, which portion is shaped - in a way that is itself known - to provide a sort of barrier to the exit of laundry, at least from the lower part of the mouth of the basket during the rotation thereof.
  • the gasket and the mouth of the basket there must always be an annular interstitial space, so to allow both oscillation of the tub and rotation of the basket.
  • the friction of the gasket can hold the above portion of the laundry item in the interstitial space and in this case the rotation of the basket can cause abrasions of the item itself.
  • the rubbing friction can also cause evaporation of the water present in the trapped portion of the laundry item and consequently cause also damage to the gasket.
  • laundry washing machines have been proposed that are provided with an appropriate device called “laundry detacher” or “laundry rejector”, essentially consisting of a deflecting member, provided on the gasket and usually made of resilient material, and in some cases having a rigid core fixed to a front flange of the tub.
  • the deflecting member crosses a limited zone of the above-said interstitial space, typically in the upper dead point region of the basket, and it is shaped to protrude toward the inside of the front opening of the basket itself, proximal to its edge.
  • the object of the present invention is that of providing a front- loading laundry washing machine provided with a rejector device that allows the reduction of the risk of damaging of the laundry items with respect to the known solutions.
  • FIG. 1 is a schematic front view of a laundry washer according to the present invention
  • FIG. 2 is a schematic representation in section of the machine of figure 1 with the illustration of only the components that are useful for the purpose of understanding the present invention
  • figure 3 is a schematic section along line III - III of figure 1 ;
  • - figure 4 is a schematic representation, similar to that of figure 2, of a machine according to a variant of the invention;
  • - figure 5 is a schematic section along line V - V of figure 4;
  • FIG. 6 is a diagram representing some of the steps of an operating cycle of a machine according to the invention.
  • figure 7 is a magnified detail of figure 6.
  • number 1 indicates as a whole a front-loading laundry washing machine according to the invention.
  • the machine 1 comprises a supporting structure or cabinet 2, inside of which a tub 3 is elastically supported in a known manner. Inside the tub 3 a perforated laundry basket 4 is mounted so as to allow it to rotate around an axis A, through an electric motor 5.
  • the tub 3 and the basket 4 have corresponding front openings, indicated with 3A and 4A respectively, and the basket 4 is accessible to the user through an opening indicated with 2A in figure 3 provided in the front wall of the cabinet 2.
  • the openings 2A, 3A and 4A are substantially co-axial or in any case aligned with each other, preferably along the axis A.
  • a door 6 is provided in correspondence to opening 2 A, having a frame 6A hinged in a know manner to the cabinet 2, and to which a containing body 6B is associated, preferably transparent, for example made of glass.
  • the containing body 6B is shaped to protrude toward the inside of the cabinet 2 in proximity to the loading mouth of the basket 4, that is, to its slightly protruding front part that delimits the opening 4A.
  • the inner part of the body 6B could possibly extend up to the area of the opening 4A, provided, in every case, that between the edge delimiting such opening and the body 6B a certain interstitial space must always be provided, since - during the functioning of the machine - the group comprising the tub and the basket is capable of oscillating inside the cabinet 2, while the door 6 is in a fixed position.
  • gasket 7 with an overall tubular shape is mounted.
  • the opposite end of the gasket 7 is connected in sealed manner to a flange-like front part 3B of the tub 3, so as to circumscribe the corresponding opening 3A, with the opening 4A of the basket that opens in the generally tubular conduit defined by the gasket 7.
  • the gasket 7 in order to allow the oscillation of the tub-basket assembly and rotation of the basket, the gasket 7 must have a certain axial extension. In addition, a certain free space or annular interstitial space, indicated with G in figure 3, must be provided between the body 6B, the mouth of the basket 4 and the gasket itself.
  • number 8 indicates as a whole a washing agent dispenser, of a known type, for example having a drawer provided with three single-dose compartments to contain the respective washing agents. The above- said drawer is slidingly housed into a hopper-like container having a lower outlet connected to tub 3, through a tube 9. Number 10 indicates valve means, having an inlet for connection to a domestic water feeding network 1 1.
  • the dispenser 8 and the valve means 10 provide for the selected and controlled transit of a flow of water coming from the network 1 1 through one of the above-said compartments, depending upon the functioning phase of the machine 1 ; water, after passing through the compartment of interest and carrying with it any washing agents that may be present, goes into the above-said hopper-like container to then reach the tub 3 through the tube 9.
  • Number 12 indicates a drain conduit, having one end connected to an opening in the lower region of the tub 3 and the other end destined for attachment to the inlet of a sewage conduit 13.
  • a discharge pump 14 is provided along conduit 12.
  • Number 15 indicates as a whole the manual programming means of the machine 1 , or its user-interface.
