Definitions

  • the invention concerns a dispensing device for liquid or powder detergents, which is apt to be fitted in an aperture provided in an internal wall of a wash chamber, in particular in the internal wall of the loading door of a dishwasher or similar machine, the device having the features defined in the preamble of Claim 1.
  • a detergent dispensing device in which reversaly oriented and elastically yielding tongue means are provided on the outer walls of the detergent container, which engage the turned down edge of an aperture in a wall portion of the washing machine and cooperate with an oppositely oriented peripheral edge of the same container to retain the same in the aperture of the wall of said machine.
  • no means are provided to prevent the yielding of the retaining tongues and their deformation caused during the use of the washing machine, therefore no firm fastening of the device is allowed.
  • a fastening device for fastening an apparatus to an aperture of a wall, preventing axial displacement of the apparatus; rearwar oriented hooking tongues are formed on the front face of the apparatus to cooperate with cam means are provided on a shoulder of the same apparatus and a rotatable annular member to lock said apparatus against the wall.
  • the fastening device according to FR-A-2.541.738 does not allow automatic fitting of the apparatus and therefore could not be used in combination with different snap-hooking device.
  • an object of the invention is to provide a detergent dispensing device for dishwashing machines, which is provided with snap-fitting means allowing a firm and reliable fitting in an aperture of a wall of the washing chamber of the machine.
  • a further object of this invention is to provide a dispensing device, as defined above, which is provided with fastening means allowing a fully automatic fitting of the device that can withstand to stress or deformations of plastic material, caused by repeated thermal cycles during use of the machine.
  • a detergent dispensing device for dishwashers or similar machines comprising fastening means for its fitting in an aperture of an internal wall of a wash chamber, in particular in the wall of the loading and unloading door of a dishwasher, according to claim 1.
  • reference 10 indicates a general type of detergent dispensing device fitted in an aperture provided in an internal wall 11 of the wash chamber of a dishwashing machine; as shown in figure 2, the aperture in the wall 11 of the chamber, has inwardly bent peripheral edges 12 to which the dispensing de vice 10 is attached, though the bent edges 12 may be omitted.
  • the device 10 usually comprises a body defining the trays for the detergent, said body being delimited by lateral walls 13 provided with a laterally which extend from an outwardly protruding outer peripheral edge 14 on the body of the dispensing device 10.
  • the body 10 of the dispensing device comprises a plurality of elastically flexible damping tongues 15 which are arranged parallel to the lateral walls 13 and positioned at a short distance from the peripheral edge 14 of the body.
  • Each tongue 15 is rearwardly directed and protruding towards inside from the peripheral edge 14 and comprises an enlarged head 16 having a step-shaped front portion 17 and an inclined surface 18 to facilitate and enable the automatic insertion of the device through the aperture in the wall 11 by partially elastically bending tougues 15 towards the wall 13 of the body 10.
  • reference number 19 indicates a sealing gasket which is disposed between the wall 11 of the dishwashing machine and the flange 14 of the dispensing device.
  • the fastening means of the device also comprise a peripheral frame 20, or equivalent element, which partly or totally surrounds the body of the dispensing device.
  • the frame 20 has a flat base portion 21 which come into contact with the internal face of the wall 11 which is opposite the one in contact with the sealing gasket 19, as well as comprises one or more elastically flexible lugs 22 which will come into contact with the step-shaped front surface 17, of the enlarged head 16 of the flexible tongues 15 attaching the dispensing device to the aperture of the wash chamber wall 11.
  • each flexible lug 22 of the fastening frame has a protruding edge portion 23, of triangular shape, which will engage of be brought into contact with the corresponding opposing flexible tongue 15 of the dispensing device.
  • the fastening frame 20 comprises a clamping strip 24 suitably spaced from the lugs 22, which is wedged with a certain pressure into the gap 25 between the opposing faces of a lateral wall 13 of the body 10 of the dispensing device and the aforesaid clamping tongues 15.
  • the fastening frame 20 is prevented from being displaced, thereby guaranteeing a fastening arrangement that is practical and secure in use and which remains such even when the whole device is subject to repeated heating and cooling cycles, as normally happens during use of the relevant dishwashing machines.
  • the particular staggered positioning of the clamping strip 24 and the fastening frame 20 has the effect that any force or action tending to make the frame 20 rotate will always cause the latter to adhere still more both against the tongues 15 of the dispensing device and against the wall 11 of the wash chamber of the machine.
  • a preferred embodiment of the fastening frame 20 is shown in the views in figures 3 to 5.
  • the frame 20 takes the form of a rectangular frame, in two separate parts 20a and 20b that will fit around the entire body of the dispensing device, on four sides.
  • Each half 20a and 20b of the frame essentially comprises one channel-shaped element 26 having inner wall provided with a plurality of elastically flexible lugs 22 and a strip or strip portions 24 having reinforcement bridging web member to give the channel the requisite rigidity.
  • Each clamping lug 22, as previously described, has an triangular-shaped edge 23 which will engage with the steps 17 of the enlarged head 16 of a matching tongue of the dispensing device.
  • the design of the clamping frame in two parts is advantageous because it facilitates easy adaptation to any practical needs that may be encountered in fitting the dispensing devices in question.
  • the frame part 20b illustrated by dashed lines in figure 3 is identical in shape to the frame part 20a shown by a continuous lines.
  • the frame 20 surrounds the whole periphery of the body 10 of the dispensing device although the clamping frame could be limited so as to attach only onto two opposing sides or walls of the device, or only along a part of them, without however thereby departing from the innovative principles claimed for this invention.
