Definitions

  • the invention relates to a device for height adjustment the upper baskets of dishwashers with an am Dish rack attachable basket plate and one with this cooperating, with the pull-out rail of the crockery basket in Engageable roller plate, wherein one of the plates at least one shift gate and the other board at least a movable in the at least one backdrop guide body has, so by a vertical movement of the dish rack Lowering and raising the dish rack is possible wherein the provided with at least one shift gate plate is made of a thermoplastic material.
  • the guide body (s) in two end positions bring in which the dish rack either its upper position or assumes its lower position.
  • Adjustment is, for example, a lowering of the dish rack by 35 mm by a one-handed, vertical movement the crockery basket possible.
  • the kinematic Function of the height adjustment device with fully loaded crockery baskets with a harness weight up to 10 kg and at an operation immediately after rinsing at temperatures up to 70 ° C is no longer guaranteed.
  • the height adjustment device is attached to the rear end of the basket so that the Guideways on the backdrop a correspondingly high surface pressure must absorb, due to the torques by the weight distribution in the basket in conjunction with the Leverage results. Under extreme weight and / or temperature conditions This can lead to a mutual jamming the two plates are coming.
  • the present invention is based on the object, the known Height adjustment device educate so that a perfect function of the adjusting device in all Operating cases is guaranteed.
  • the object is with a device of the aforementioned Art solved according to the invention that with the at least one shift gate plate provided with a made of a filler reinforced thermoplastic is and the plate with the at least one guide body is made of a flexible plastic material, so that a clipping of the two plates is possible. Also at high surface pressures, it comes here to deformations of the plastic, so that no tilting of the two Plates can occur together.
  • the one or more guide body of a Plastic be made with good sliding properties. Thereby can be a favorable sliding behavior of the two plates achieve each other. It is important to ensure that both the material for the basket plate and the material sufficient thermal aging resistance for the roll plate, Resistance to chemicals and detergents and a hydrolysis resistance for temperatures up to 80 ° C have.
  • the plate with the At least one shift gate has glass fiber reinforced Polyamide with a filler grade of 5 - 60% by weight proven.
  • As an excellent material combination of the two Plates at least in the range of at least one shift gate and the guide body has come up for the plate with the at least one shift gate PA6 with a gain with 25-30% glass fiber and for the plate with the at least a guide body unreinforced POM proven. That shows the plate with the shift gate has a higher stiffness and Surface hardness than the other plate. Both materials are also characterized by a sufficient Chemikaliensowie Hydrolysis and temperature resistance. By the Flexibility of the POM as a material is also a Verklipsen the both plates possible with each other.
  • a lubricant additive in the material for the plate with the at least be included a shift gate in addition to the mutual sliding behavior of the two plates.
  • the material for the Plate with the at least one guide body may be a lubricant be added. The addition of such lubricant ensures a favorable sliding behavior even with complicated formed Wegkulissen and / or large contact surfaces between the guide bodies and the shift gates.
  • Fig. 1 shows a roller plate 10, which with the one shown in Fig. 2 Basket plate 20 cooperates and together with this a height adjustment for an upper dish rack a dishwasher, which is not shown here, forms.
  • the roller plate 10 has two fasteners 11 for Rollers on, with which the plate in the puller rail too the crockery basket is inserted.
  • There are also sliding blocks 13 on the roller plate 10 provided, which is also the leadership of the roll plate 10 on the basket plate 20 in the guide openings 21st serve.
  • the basket plate 20 of FIG. 2 is by means of snap elements 23 attached to the crockery basket and is thus firmly with this connected.
  • Fig. 3 now illustrates the adjustment of the roller plate 10th opposite the basket plate 20, wherein Fig. 3a, the upper end position the roller plate 10 shows.
  • Fig. 3b and Fig. 3c show the both plates 10 and 20 in intermediate positions while the Fig. 3d and Fig. 3e, the plates 10 and 20 in the lower Rndposition demonstrate.
  • the bolt moves 14 in the shift gate 22 of the basket plate 20.
  • the adjustment is simply by a vertical movement on the dish rack triggered by the basket plate 20 also moved becomes. Since the roller plate 10 in the pull-out rails of the Dishwasher is guided results from a relative adjustment the basket plate 20 to the roller plate 10 and a relative adjustment the dish rack to the pull-out rail and thus a different height position in the dishwasher.
  • the sliding blocks 13 and snap elements 12 in the guide openings 21 of the basket plate 20 In a full loaded dish rack can thereby the surface pressures between the snap elements 1.2 and the sliding blocks 13th on the one hand and the guide openings 21 on the other hand very be high. Nevertheless, a perfect function of the height adjustment to ensure the basket plate 20th made of a glass-fiber or mineral-reinforced plastic.
  • the Roller plate 10 may be made of an unreinforced material, for example POM be made.
  • both plates 10 and 20 can also use materials with a lubricant additive, so that the adjustment of the dish rack even more effortless becomes.
  • the plates could also only in Area of mutual contact from the tribologically to each other matched materials and otherwise out be made of a cheaper plastic such as polyamide.
  • a cheaper plastic such as polyamide.
