Definitions

  • a metering device for dispensing detergent tablets from a storage container into the useful space of a dishwashing machine in which a substantially impermeable seal is arranged between the storage container and the usable space.
  • the storage container is designed to receive a loose bed of tablets and the lock has a transport device, for example in the form of a cellular wheel, for actively transporting the tablets through.
  • the outer circumference of the cellular wheel and / or the inner circumference of the cavity in which the cellular wheel is running may be additionally provided with seals to ensure impermeability to wrinkles.
  • the invention has for its object to provide a metering device for dispensing detergent moldings from a reservoir into a washing compartment of a domestic dishwasher, which allows a reliable automatic addition of detergent tablets for several successive rinses.
  • detergent tablets is to be understood as meaning all tablets having a defined external shape which contain any ingredients which can be used for dishwashing, such as tablets, pellets, granules or capsules Rather, molded articles should also be encompassed which comprise addition agents for use in rinse cycles, for water softening or conditioning, etc.
  • the reservoir is that region of the dosing device which contains the supply of detergent moldings It can be refillable or can also be exchangeable, for example in the form of a cartridge
  • the reservoir is designed to receive a bed, in particular loose bed, of detergent tablets the storeroom lie randomly oriented and are not magazined in a given geometric arrangement.
  • the inventive design of the reservoir for receiving a bed of detergent moldings allows easy storage even larger amounts of detergent moldings. A complicated magazine the tablets is not required.
  • the attachment of the partitions to the drive cylinder must be designed such that the radially projecting from the drive cylinder partitions are rotatably connected to the drive cylinder, so that they rotate with the drive cylinder.
  • the partitions are formed integrally with the drive cylinder, but they can also be fixed by means of known fastening means on the drive cylinder.
  • the design and in particular the radial extent of the partitions also affect the metering accuracy and the tendency of the detergent moldings to wedging, jamming or bridging.
  • a surprisingly high dosing accuracy and a virtually complete avoidance of wedges, jamming or shaped body bridges can be achieved if the radial extent of the partitions increases the radial distance between the lateral surface of the drive cylinder and the inner walls of the cavity by 10% to 50%, in particular by 10% to Exceeds 30%.
  • the partitions are elastic only in partial areas, which means in reverse that the remaining portions of the partitions are not elastic.
  • the sealing forces acting on the inner surfaces of the cavity can be adapted optimally to the respective application and / or the respective environmental conditions both in the radial and in the axial direction.
  • this advantage can also be achieved by virtue of the fact that the dividing walls each have partial areas with different elastic properties.
  • the partitions in their, the drive cylinder remote end portions are formed elastically. In this way, the shearing forces acting on the partitions on the walls of the cavity can be minimized.

  • the cell wheel When compressed in the axial direction, the cell wheel may expand in a radial direction.
  • the axial direction is preferably oriented parallel to a rotational axis of the drive cylinder or corresponds to this.
  • the drive cylinder and / or the partition walls are compressible.

  • the bottom 7 may be made of a plastic material.
  • the dishwasher 1 also has a metering device 100.
  • the metering device 100 is arranged in the example of FIG. 1 on the door 3, so that, when the door 3 is closed, it is aligned with the washing compartment 4. This advantageously makes it possible for the metering device 100 to be able to meter detergent molding into the washing compartment 4.

  • the partitions 108 are thereby elastically deformed during a rotational movement of the cellular wheel 105 and thus press with a restoring force (spring force) and thus sealingly, in particular wrasendicht, against the inner walls 1 1 1 of the cavity 104.
  • the cellular 105 forms a wrasen Notice lock in this way, which means that during normal operation of the household dishwasher 1 moisture from the washing compartment 4 through the lock in the reservoir 101 can not or at most to penetrate to such an extent that the cleaning agent Shaped bodies 102 are not appreciably dissolved, stick together, clump together or the like.
  • Fig. 3 shows a further embodiment of the metering device 100 according to the invention, wherein for reasons of clarity, the reservoir 101 is only partially shown. This differs from the embodiment shown in FIG. 2 only in that an axis of rotation 1 12 of the drive cylinder 106 is displaced in the direction of the reservoir 101 in comparison to an axis of symmetry 1 13 of the cavity 104.
  • the receiving volume of the transport chambers 107 with increasing approach of the transport chamber 107 to the discharge chute 109 for ejecting the detergent tablets 102 becomes increasingly larger. This leads to a loosening of the detergent moldings 102 and consequently to an unimpeded movement of the cellular wheel 105 and to an optimal dosage, which in turn results in a good cleaning performance.

Abstract

L'invention concerne un dispositif de dosage (100) permettant de distribuer des corps moulés de produit de nettoyage (102) à partir d'un réservoir (101), conçu pour recevoir un chargement de corps moulés de produit de nettoyage (102) dans une enceinte de lavage (4) d'un lave-vaisselle ménager (1). Une roue cellulaire (105), servant à transporter de manière active les corps moulés de produit de nettoyage (102) du réservoir (101) vers l'enceinte de lavage (4), est montée de manière rotative dans une cavité (104) et comporte plusieurs chambres de transport (107), permettant de recevoir des corps moulés de produit de nettoyage (102). Les chambres de transport (107) individuelles sont chacune séparées les unes des autres par des parois de séparation (108) et les parois de séparation (108) sont fixées à un cylindre d'entraînement (106) de la roue cellulaire (105). Les parois de séparation (108) sont agencées de manière à être élastiques au moins dans des zones partielles et l'étendue radiale des parois de séparation (108) est supérieure à la distance radiale (D) entre la surface d'enveloppe (110) du cylindre d'entraînement (106) et les parois internes (111) de la cavité (104).
