Definitions

  • the invention refers to a dishwasher with a rinsing container with a fine filter outlet in which is placed a removable coarse filter and which has a water collecting trough around the fine filter outlet with connection branches for a circulation pump and a drainage pump, in which the pot shaped coarse filter in the casing wall has horizontal slit-shaped openings for soft food particles.
  • a dishwasher of this type is known from DE 34 26 661 C1.
  • this known dishwasher there are areas with small hole openings in the base and/or casing of the lower area of the coarse filter with a mesh size which retains the detergent granules which enter the coarse filter.
  • the mesh size is thus selected to be approx. 1 mm.
  • the coarse filter retains not only heavy small particles but also voluminous coarse particles able to be sucked out. This very quickly leads to the small openings becoming blocked so that their intended function is lost and only the horizontally aligned slit-shaped openings for soft food particles remain effective. In this way, the voluminous coarse particles which are able to be sucked out remain in the coarse filter and also close these openings which finally leads to faults in the circulation and drainage operations.
  • the task of the invention is to improve the function of the coarse filter in a dishwasher as mentioned at the start in such a way that heavy small particles are kept back but voluminous light coarse particles are able to pass the coarse filter and soft food particles can be sucked out from the coarse filter without any danger of the filter openings being blocked.
  • the lower area of the casing wall connected with the base of the coarse filter (10) has at least one layer of slit-shaped openings (14) for soft food particles and has, above this apposite to the base, large outlet openings (15) for coarse particles with a specific gravity of less than 1 which are able to be sucked out, the lower part of the coarse filter up to the outlet openings (15) forming a retaining chamber for small particles with a specific gravity of more than 1.
  • the extraction of soft food particles from the coarse filter is eased by there also being suction openings in the base of the coarse filter for soft food particles removable by suction.
  • the outlet openings are designed as rectangular openings of 6 x 3 mm.
  • the coarse filter is additionally planned for the coarse filter to be supported by a band at the entrance to the fine filter outlet and for this band to have slits and a retaining ring to be shaped on the band using vertical supports which both protrude into the rinsing container; large inlet openings to be are formed to the coarse filter between the supports to improve the flow through the gap between the coarse filter and the fine filter.
  • the removal of the coarse filter for cleaning is simplified by there being a gap in the fine filter of the fine filter outlet surrounding the coarse filter.
  • the figures show the structure of a pot-shaped coarse filter 10 which, as shown in Figures 2 and 3, is removably placed in a fine filter outlet 20 of a dishwasher.
  • the fine filter outlet 20 has small openings 21 and surrounds an area of the coarse filter 10 connected to a band (11).
  • the fine filter outlet 20 is built into the base of a rinsing container which is not shown and in such a way that the rinsing water is always fed to the coarse filter 10 placed in the fine filter outlet 20, both in circulation and extraction modes.
  • a water collecting trough is arranged which has connection supports for a circulation and extraction pump.
  • the coarse filter 10 has four vertical supports 18 which are closed off from it by a retaining ring 17.
  • the supports 18 with the retaining ring 17 form a handle so that the coarse filter 10 can be grasped and is able to be removed easily from the fine filter outlet 20.
  • the supports 18 and the retaining ring 17 therefore protrude into the rinsing container.
  • One layer of this type of opening 14 is also connected over the base of the coarse filter 10. Over this layer of openings 14, four large outlet openings 15, approx. 12mm x 30mm, are arranged in the casing wall around the circumference.
  • the base of the coarse filter 10 has rectangular extraction openings 16, approx. 3mm x 6mm, through which soft food particles can be sucked out.
  • the lower part of the coarse filter 10 up to the outlet opening 15 forms a retaining chamber for small particles with a specific gravity greater than 1 whilst voluminous coarse particles with a specific gravity less than 1 which can be removed by suction can pass through the outlet openings 15 of the coarse filter 10.
  • a retaining element 12 formed in the base of the coarse filter 10 using which the coarse filter 10 can additionally be locked in the fine filter outlet 20 or the outlet trough.
  • the coarse filter 10 can be easily loosened for cleaning and removed from the fine filter outlet 20.
