Definitions

  • the invention relates to a screening device for a dishwasher, which is arranged in the bottom region of the dishwasher and keeps out coarse dirt from the suction for the circulation pump.
  • a screening device in which distributed over a screen surface a plurality of screen holes are formed.
  • the holes are not uniform size but have different sizes.
  • the hole size is statistically distributed around a mean hole size with deviation of the hole size down and up.
  • the sieve device is an area sieve, as it is arranged as a filter device in front of the intake opening of a circulation pump of a dishwasher.
  • the screen surface is structured in itself, i. In relation to a sieve base surface or plane, there are sieve surface regions which project upwards or are lowered downwards.
  • Sieve base here means the area that the sieve would occupy if no structuring were present.
  • the screen surface itself can be formed overall, for example as a funnel-shaped surface, conical surface, conical surface or the like. Elevations or depressions means an increase or decrease in relation to this area.
  • Elevations or depressions means an increase or decrease in relation to this area.
  • the deepest points of depressions can be assumed to be the base area or the highest points of the elevations as base area and the structures formed for this notional base area then as elevations and / or depressions be accepted.
  • the structuring of the sieve surface favors the flushing of clogged sieve holes in the higher sieve areas.
  • the sieve holes are larger in the raised areas than in the lowered areas of the sieve surface or as the sieve holes in the plane of the sieve base.
  • larger contaminant particles preferentially accumulate in the deeper screen area areas, and smaller contaminant particles, which are more easily entrained by the flow, fall through the larger screen holes in the raised areas, so that the screen holes in the raised areas are mostly kept clear.
  • channels are formed which run in the direction of the height gradient of the sieve base surface.
  • contaminant particles within the channels are directed to deeper areas of the screen surface.
  • an opening is formed there, in which, for example, a coarse / fine sieve with large openings is provided, so that the contamination particles transported along the sieve surface in the channels enter the coarse / fine sieve and are thereby removed from the circulation circuit.
  • the cross section of the holes is not round, but as a polygon (triangle, square, etc.) is formed, the dripping or flowing through the flushing liquid is promoted through the holes.
  • plastic as a base material of the screening device or screen surface dripping from the plastic sieve is favored in the underlying collecting tray despite the higher interfacial tension.
  • the sieve device itself is made of plastic or substantially of plastic and the sieve holes have a cross section with at least one edge in order to derive by capillary action the moisture from the top of the sieve surface towards the bottom.
  • the holes do not have to have a different size, but merely have a different size according to an advantageous embodiment.
  • FIG. 1 shows a schematic, perspective view of a surface sieve 1, which can be used in the bottom area of the washing compartment of a dishwasher.
  • a central opening 2 In the middle of a central opening 2 is formed, in which a coarse / fine screen is used in a conventional manner.
  • the rinsing liquid collecting at the bottom or dishwasher bottom passes through the holes of the flat screen 1 into a space underneath, from which a circulation pump sucks the rinsing liquid and distributes it via spray arms back to the items to be stored in the dishwasher interior.
  • the rinsing fluid passing through the central opening 2 into the coarse / fine screen also passes either through the fine screen of the coarse / fine sieve into the space below the area sieve 1 or into the intake area of an emptying pump which sucks the sucked-in rinsing liquid out of the dishwasher.
  • a recess 3 is formed, with which the surface sieve 1 can be pushed on via a connecting piece of a lower spray arm.
  • the base 4 of the flat screen 1 is slightly funnel-shaped, wherein the central opening 2 the represents the lowest point of the base 4.
  • Around the central opening 2 around a center region 6 in the plane of the base 4 is formed (ie slightly funnel-shaped or tapered to the central opening 2).
  • Around the center region 6 around flat bulges 5 are formed, which are approximately 3 to 5 mm offset upwards to the base 4 are bent. Between the bulges 5 run channels 7 in the plane of the base 4, wherein, the grooves 7 extend radially toward the central opening 2.
  • the hole diameter of the wire holes in the different areas is different in size. In the middle area, the hole diameter is about 0.6 mm. In the area of the adjoining base area 4, the hole diameter is 0.75 mm. In the area of the bulges 5 and elevations, the hole diameter is 1 or 1.2 mm.
  • the hole density ie the number of holes per unit area, is the same in all three surface areas 4, 6, 5. In one embodiment, it is provided to increase the hole density with decreasing hole diameter.
