Definitions

  • the present invention relates to a washing machine with a detergent distributor comprising a drawer movable within a housing provided in the front part of the machine.
  • extractable drawers with a plurality of compartments are commonly known, for example from document GB-A-1 211 560 , into which the user fills the detergent, fabric softener, and bleach. After the drawer is pushed in and the program is started, the machine automatically flushes the detergents into the soap container of the machine at the right time.
  • the guide of this drawer in the corresponding housing or box, into which the drawer is pushed and which is responsible for directing the water into the individual drawer chamber consists typically of grooves on the left and right side of the box, into which two corresponding ledges of the drawer are slidably inserted.
  • the main elements that can be opened are the door, the detergent drawer, and the filter door, which is why they are opened and touched by the customers.
  • the sturdiness perceived in the inspection is a very important factor for the purchase decision.
  • the present invention eliminates the tolerances in the drawer guide and therefore prevents motions that are not in direction of the guide, with a predetermined spring force.
  • the drawer can be moved only against a predetermined small resistance and the user perceives such resistance as sturdiness and therefore as good quality.
  • the present invention solves the task of preventing the wobbling of the drawer when moving it in and out, allowing the drawer to be pulled out and pushing it easily without the risk of jamming.
  • the drawer, and in particular its guide give the user a solid, stable, and user-friendly impression. The task is solved according to the attached claims.
  • the invention can provide a detergent distributor whose drawer is devoid of tolerances in its movement in and out of its'housing, which is therefore more reliable to use.
  • a washing machine 10 presents a casing 12 provided, in its front wall 12a, with a detergent distributor 14 comprising a drawer 16 and a housing 18 in which the drawer 16 is slidably mounted.
  • the drawer 16 is provided with detergent and/or softener/bleach compartment D and, on each of its sides, with a U-shaped edge 16a.
  • Each edge 16a is provided with two slide bars 20 and 22, equipped with integral spring elements S, that are attached between the drawer 16 and the housing 18 so as to cooperate with corresponding rails 24 and 26 of the housing 18.
  • Each of the slide bars 20 and 22 present, opposite to sliding surfaces 20a and 22a respectively, shaped pins 28 which are snap-engaged within corresponding openings 30 in the edges 16a of the drawer 16 so as to fix longitudinally the sliding bars 20 and 22 to the drawer 16, and allowing a lateral movement orthogonal to the movement of the drawer, on a horizontal plane for the bar 20 and on a vertical plane for the bar 22 respectively.
  • these sliding bars 20 and 22 are clipped to the drawer 16 but they might also be clipped to the housing 18 as well.
  • the drawer 16 can therefore be moved easily and only in the direction of the rails, it does not wobble, and gives to the user a guided, stable, and solid impression.
  • the task of compensating tolerances is solved by suspending the drawer 16 on rollers 31 in horizontal and vertical direction, in addition to the sliding bars 20, 22, wherein the rollers 31 are held by roller holders 32 in corresponding horizontal and vertical roller grooves 34 and 36 respectively provided in the housing 18.
  • Each roller holder 32 is comb shaped and has a plurality of teeth 32a on which the rollers 31 are rotatably mounted:
  • the roller holders 32 are supported in a fixed configuration in the grooves 34 and 36 so that the rollers 31 can rotate freely and can support the sliding bars 20 and 22 when the drawer 16 is pushed in or pulled out of the housing 18 with a reduced friction compared to the first embodiment.
  • the resilient sliding bars could be installed in the housing 18 instead of installing them in the drawer 16; in such case the rollers 31 and related roller holders 32 would be installed in grooves of the drawer 16.
  • the task of compensating tolerances is solved by resilient portions of the drawer and of the housing which replace the resilient sliding bars of the previous embodiments.
  • the resilient portions consist of three wave-shaped resilient elements 33 each, which are integrally molded with the drawer along the drawer edges 16a.
  • the shape of the resilient elements 33 is so that the drawer 18 can be removed from the mould, used in the injection-molding machine, in the regular removal direction.
  • a fourth resilient element 35 is molded in a manner that such element consists of the bent rear edge of the drawer side and in addition, on the bottom part, of a protruding nipple 35a which facilitates inserting the drawer 16 into the drawer housing 18 with a suitable insertion slant.
  • the drawer 16 at its back portion is also provided with slots 37 that facilitates the spring movement.
  • resilient portions 38 On the housing side, there are provided resilient portions 38 that cooperate with an upper plane surface 16a of the drawer 16.
  • the wave-shaped resilient elements could be integral with the side walls of the housing 18 instead of being provided on the edges 16a of the side of the drawer 16.
  • a resilient element 40 that consists of an auxiliary longitudinal side wall of the drawer 16 and it is molded on the left and right side of the drawer, wherein the side wall 40 can act as a lateral spring due to its width.
  • the longitudinal auxiliary side wall 40 can also be wave-shaped (as shown in figure 5 ).
  • the task of compensating tolerances is solved by a drawer 42 that is guided by one plastic rail 44 on each of the two sides, wherein the rails 44 may be extended like a telescope and inserted into the drawer 18.
  • the rails 44 are equipped with spring elements 44a and 44b in horizontal and vertical direction respectively to make up for the tolerances between the rails and the drawer guide in the housing and to create a wobble-free drawer guide.
