Definitions

  • This invention refers to a dishwashing machine of the type described in the preamble of Claim 1.
  • a preset quantity of water is input into the wash tub and said quantity of water is used for the whole wash cycle of the operative programme selected by the user.
  • the wash fluid is forced through the above recirculation pump to some spraying elements located inside the tub, which are used to spray the fluid on the crockery. Once the crockery has been sprayed, the fluid flows back to the tub bottom and is collected into said trap to be recirculated again through said pump. At the end of the wash cycle the recirculation pump stops and the above discharge pump starts operating to discharge the fluid used during the previous step from the tub to a connecting duct of the sewer system or similar.
  • dishwashing machines need a filtering system for the fluid input in the recirculation circuit, to prevent that significant soil particles removed from the crockery may be recirculated again and reduce washing performance or obstruct the recirculating pump.
  • filtering means shall be provided to prevent that significant soil particles removed from the crockery or any foreign matter, such as a tooth-picks, may block the discharge pump.
  • the fluid trap To this purpose it is known for the fluid trap to have a filtering system provided with one or more filters of different size and mesh to obtain the desired purpose of filtering the fluid, which should first be recirculated and then discharged from the machine.
  • Such a system is known for instance from French patent application FR-A-2.503.557.
  • Such an application describes a filtering system comprising a plurality of filters secured in line with the trap, in particular :
  • a first problem is that due partially to the trap configuration and partially to the recirculating pump action the direction of the fluid filtered by the microfilter always flows the same direction, i.e. it is practically always one same part of the microfilter that works on the fluid flow sucted by the recirculation pump.
  • this object is obtained by providing a dishwashing machine incorporating the characteristics as per the annexed Claims.
  • reference number 1 indicates the stainless steel bottom of the wash tub of the dishwasher according to the present invention.
  • the bottom 1 goes further downwards in its central area where a fluid trap 2 is secured to the bottom as normally known.
  • the lower side of the trap 2 houses the suction pipe 3 of a discharge pump, whereas on the side of the trap 2 is located the suction pipe 4 of a recirculation pump.
  • the trap 2 is covered on its upper part by a fine filter 5 substantially shaped like a funnel with a large opening radius. Said fine filter 5 goes further downwards with its median area inside the trap with a coupling side 6. Said coupling side 6 extends in the illustrated case down to the suction pipe inlet 3 of the discharge pump.
  • the coupling side 6 of fine filter 5 is surrounded by a tubular filter with a very fine mesh indicated with 7, said filter with very fine mesh 7, or microfilter, whose section is larger with respect to the coupling side 6 and is therefore at a certain distance from it.
  • microfilter 7 extends from the top downwards, i.e. from the funnel filter top 5 down to the inlet of suction pipe 3 of the discharge filter.
  • the microfilter 7 forms a cylindric surface enclosing the coupling side 6 of funnel-shaped fine filter 5.
  • a large mesh tumbler filter 8 with a handle 8A is inserted from the top in a removable way in the coupling side 6 of the funnel filter 5.
  • the microfilter 7 is not a fixed one as it is usual according to the known state of the art, but is removable under the effect of a fluid flow through the trap 2. This is obtained by two conditions.
  • microfilter 7 has some protusions, such as protuding blades, indicated by reference number 9 in the figures 2 and 3.
  • the microfilter 7 is coupled on its upper side according to a known technology to funnel filter 5 in a rotary manner. This can be obtained for instance through a round projection on the lower side of filter 5 and a corresponding seat being slightly larger than the projection on the upper end of microfilter 7.
  • the dishwashing machine operates as follows.
  • the fluid When the recirculating pump is in operation, the fluid is sucted towards the duct 4 in the direction shown by the arrows of Fig. 1. Most part of said fluid follows the path shown by arrow 10, i.e. through the funnel fine filter 5, which retains the large and fine soil particles from the washing fluid; then said soil particles will go to the coupling side 6 of the filter 5.
  • the tiniest soil particles settle in the suction pipe 3 of the discharge pump whereas the larger ones (eg. a tiny bone) that could cause the discharge pump to be jammed, are retained by the large mesh filter 8.
  • the trap 2 can be favourably configurated to cause a sort of internal vortex so that at least a part of the fluid flow sucted towards the suction duct 4 can surely strike the blades 9 and cause the microfilter 7 to rotate.
  • This concept is illustrated by the schematic section of Fig. 4 using the same reference numbers of Figs. 1 and 2.
  • the suction duct 4 can be arranged in a nearly tangential position against the main body of trap 2 to obtain the required result. From said figure it can also be noticed how the protusions 9 can favourably be either curved or inclined similar to the blades of a turbine.
  • said rotary motion has the significant result that according to the present invention and in respect to the known state of the art a different section of the microfilter 7 will always appear on the suction branch 4 of the recirculation pump 7 to ensure a higher performance of the dishwasher filtering system.
  • Another significant result according to the present invention is also the fact that the rotary action of the microfilter 7 favours the removal of soil particles from the surface of the microfilter itself to further improve the system performance, thus acquiring self-cleaning characteristics.
  • the system performance is further improved by the fact that the rotation of microfilter 7 also causes an eddy effect of the washing fluid in the substantially central area of the filtering system.
  • the fluid portion following the path shown by the arrows 12 causes the tiny soil particles eventually retained on the cylindrical inside wall of microfilter 7 to come off.
  • the small soil particles inside the coupling section 6 of filter 5 are removed partially by the flow 12 and partially by the flow 13.
  • another portion of the fluid flows centrally according to the arrow 14 to remove the fine particles retained on the upper side of the funnel filter 5 to the suction duct 2 of the discharge pump, through the porous filter bottom 8.
  • a dishwashing machine with a filter whose motion is obtained by exploiting at least a part of the fluid flow recirculated and/or discharged from the machine.
  • said filter has a substantially cylindrical configuration and surrounds at a certain distance at least a second filter whose section is also substantially circular or coupling-shaped.
  • the mobility of the mentioned filter allows improvement of the overall efficiency of the filtering system, since different parts of the filter are continuously exposed to the flow to be filtered and its motion favours the detachment of soil particles, so that the filter according to the invention acquires selfcleaning characteristics.
  • microfilter 7 can be coupled directly to the trap 2 instead of the funnel filter 5, provided that the coupling system selected shall be such to allow an angular or rotary motion of the microfilter 7.
  • the lower side of filter 7 can have a slightly truncated shape and lay in a corresponding flared seat obtained on the duct inlet 3.
