    • D06F39/10—Filtering arrangements

Definitions

  • the present invention has as its subject a laundry washing machine, of the type described in the preamble of the annexed first claim.
  • liquid filtering means arranged before the pump; such filtering means have to be periodically cleaned, generally depending upon the types of fabric washed.
  • a further problem of the known art derives from the fact that, upon termination of a washing cycle, a certain part of the liquid tends to remain in the drainage piping circuit of the machine, before the pump; therefore, when the user removes the access cover from said filter, for its cleaning, such water residues exit the machine and can leek on to the floor of the room in which the machine is installed.
  • the aim of the present invention is that of overcoming the aforementioned drawbacks and to realise a laundry washing machine equipped with a filtering device of the liquid that is of simple realisation, contained costs and of simple use by way of the user.
  • the number 1 indicates the washing machine as a whole according to the invention; such machine 1 comprises in the known manner, a washing tub 2 within which a washing basket 3 is arranged, having a horizontal axis, which is operated with a rotary motion around such axis.
  • a drainage duct 4 is defined, which enters the intake zone of a pump 5, of the type known, which is operated when the washing cycle provides for a partial or complete emptying of the tub.
  • An auxiliary duct is indicated with 6, the first extremity 6a of which communicates with the inside of the tub 2 and arranged above the level 7 reached by the water during washing due to the effect of the rotation of the basket 3.
  • the second extremity of the auxiliary duct 6 is connected to the drainage duct 4, before the pump 5: advantageously, a union sump 8 is provided on the drainage duct 4, which further lowers the level of the drainage duct 4, and the second extremity of the auxiliary duct 6 joins in fact near to the bottom of such union sump 8.
  • the first extremity 6a of the auxiliary duct 6 is water tightly connected to the lower zone of a water tight bellows seal 10; such seal 10 connects the tub 2 to the loading opening 11 of the machine, to which a loading door 12 is arranged in a known way.
  • a seat is also obtained, indicated with 13, for a filter, indicated with 14; advantageously such filter 14 is housed in the seat 13 in a removable manner.
  • the machine also provides for a programming device, or timer, which supervises the operations of the various washing cycles that can be selected by the user of the machine; such device has not been represented in the figures for reasons of simplicity, inasmuch its realisation and functioning is known.
  • the functioning of the laundry washing machine according to the invention is the following.
  • the user after having loaded the laundry to be washed in the basket 3, through the door 12, selects the desired washing cycle and starts the machine.
  • the programming device of the machine controls the introduction of the water to the tub 2, at the beginning of the washing phase in the strict sense; in practice, during such phase, the washing water coming from the mains is made to pass through an appropriate dispensing device, in itself known and not represented in the figures, so as to transport the detergents to the washing tub 2; the water in the tub is heated by way of appropriate resistences, upon a command of the programmer of the machine, to a suitable temperature to fit the needs, for instance 60°.
  • the basket 3 is made to rotate at a determined speed, under the control of the programming device; the mechanical rotational action of the basket (which produces the movement of the laundry), together with the chemical action (determined by the presence of the detergents) and thermal action (water temperature) allows for obtaining the washing of the laundry.
  • the mechanical rotational action of the basket which produces the movement of the laundry
  • the chemical action determined by the presence of the detergents
  • thermal action water temperature
  • the rotation of the basket 3, combined with the presence of laundry within projects part of the washing liquid contained in the tub 2 against the internal wall of the tub and towards the loading door 12 which, as seen from figure 1, extends in the direction of the tub 2 and towards the interior of the basket (which has the usual frontal opening).
  • part of the washing liquid employed within the laundry washing machine is made to re-circulate by way of the basket 3, the seat 13, the duct 6, the sump 8 and the duct 4.
  • the quantity of washing liquid projected towards the loading door 12 can be increased by using a basket provided with spoons or sacks 19 on its interior surface obtained on the projecting ridges 20 for the movement of the laundry , as can be seen in figure 2, that collect the liquid from the bottom of the tub and project it from above on the laundry below.
  • Such ridges 20 can therefore be shaped so as to also favour the passage of liquid towards the door 12 and the seat 13.
  • the action of recirculating the liquid favours the gathering of fibres and small foreign bodies in the seat 13, in correspondence with the filter 14.
  • This avoids the use of a filter containing a drainage pump as is the case with the known art.
  • the position of the filter 14, according to the invention results in being much more satisfactory if compared to the known art; the same is said for its access, for which no removal of any covering element is required.
  • the ergonomic positioning and the simplified access to the filter 14 therefore stimulates its cleaning by the user, who can also keep the situation under control.
  • Another substantial advantage of the invention consists in that the stylistic line of the machine may not be disturbed by the presence, in the frontal part of the cabinet, of a small access door to the filter as is typical in the known art.
