Definitions

  • the present invention relates to a dishwasher comprising a strainer.
  • dirty kitchen items are placed onto the racks.
  • the water is delivered onto the dirty kitchen items placed onto the racks by means of the spraying members.
  • the water is delivered to the spraying members by means of the circulation pump.
  • a mechanical water guiding valve is used to guide the water to different spraying members at different times.
  • the dirt particles removed from the kitchen items with the pressure of the sprayed water sometimes scatter in the washing tub without being dissolved and leave the tub with the guidance of the water.
  • the dirt particles leaving the tub are retained by means of the strainer, microfilter and the coarse filter structures provided on the base of the tub. Thus, the dirt particles are prevented from entering the water line and clogging the water line.
  • the dirt particles retained by the strainer, the microfilter and the coarse filter structures accumulate there in the course of time, preventing a clean washing of the dishes. Therefore, the strainer, the microfilter and the coarse filter structures are removed from the washing tub and cleaned by the user at certain intervals. The same components are replaced after the washing process and the washing programs are run. However, when the strainer, the microfilter and the coarse filter structures are not properly mounted or are damaged, the filtering process cannot be efficiently realized. This causes the spraying members, the circulation pump and the mechanical valves to get clogged.
  • the aim of the present invention is the realization of a dishwasher with improved washing efficiency.
  • the dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body; a washing tub which is provided in the body; a sump wherein the water in the washing tub is collected; a filter group which filters the dirt particles in the water in the sump; a plurality of spraying members which are disposed in the washing tub and which provide the delivery of the water to the kitchen items; a circulation pump which provides the delivery of the water to the spraying members; and a mechanical water guiding valve which enables the water to be guided to the desired spraying member.
  • the filter group comprises a main strainer at the base of the washing tub, and a microfilter and a coarse filter which are provided under the main strainer. Thus, the dirt particles in the washing tub are filtered.
  • the dishwasher of the present invention comprises a straining member which is provided between the circulation pump and the mechanical water guiding valve.
  • the straining member By means of the straining member, the dirt particles, which cannot be retained by the filter group, are prevented from clogging the mechanical water guiding valve and the spraying members.
  • the dishwasher comprises an additional straining member which is provided between the filter group and the circulation pump.
  • the additional straining member By means of the additional straining member, the dirt particles passing through the filter group are retained before entering the circulation pump.
  • the dishwasher comprises the mechanical water guiding valve comprising a wheel group, a gear group and a shutter group; and the straining member which is positioned in front of the wheel group.
  • the mechanical water guiding valve comprising a wheel group, a gear group and a shutter group
  • the straining member which is positioned in front of the wheel group.
  • the dishwasher comprises a delivery live having a first delivery line which delivers the water leaving the circulation pump to the mechanical water guiding valve and a second delivery line which delivers the same to the spraying member.
  • the water delivered to the first delivery line operates the mechanical water guiding valve so as to enable the operation of the shutter group.
  • the water delivered to the second delivery line is delivered to the spraying member in connection with the shutter group in operation.
  • the dishwasher comprises a plurality of openings which are provided on the straining member; and the first delivery line which has the same cross-sectional area as the total of the areas of the openings. The water flowing through the first delivery line moves through the straining area without any decrease in the cross-sectional area.
  • the dishwasher comprises a connection line which enables the water coming from the first delivery line to return to the sump after passing through the mechanical water guiding valve.
  • the water operating the mechanical water guiding valve is delivered to the sump to be reused.
  • the dishwasher comprises the straining member which has a permeability level at least equal to that of the microfilter.
  • the particles which cannot be retained by the filter group are retained by the straining member and prevented from being delivered to the mechanical water guiding valve.
  • a dishwasher is realized, wherein the washing efficiency is improved by retaining the solid particles forming in the washing water.
  • the dishwasher (1) comprises a body (2); a washing tub (3) which is provided in the body (2) and wherein the washing process is performed; a sump (18) which is provided on the base of the washing tub (3) and wherein water is collected; a filter group (7) provided in the sump (18) and having a main strainer (4) which strains the dirt particles breaking off from the kitchen items placed into the washing tub (3) and a microfilter (5) and a coarse filter (6) which are positioned under the main strainer (4); a plurality of spraying members (8) which provide the delivery of water to the kitchen items in the washing tub (3); a circulation pump (9) which enables the water to be guided to the spraying members (8); and a mechanical water guiding valve (10) which enables the water to be guided to the desired spraying members (8) in order.
  • the dirt particles removed from the kitchen items are retained by the filter group (7).
  • the water in the washing tub (3) is collected in the sump (18).
  • the water cleansed of dirt particles by passing through the filter group (7) is delivered back to the spraying members (8) by means of the circulation pump (9).
  • the mechanical water guiding valve (10) is used to guide the water to the desired spraying member (8).
  • the dishwasher (1) of the present invention comprises a straining member (11) which is provided between the circulation pump (9) and the mechanical water guiding valve (10) and which retains the particles passing through the filter group (7).
  • the straining member (11) By means of the straining member (11), the dirt particles which cannot be retained by the filter group (7) are enabled to be retained.
  • the circulation pump (9), the mechanical water guiding valve (10) and the spraying members (8) are prevented from getting clogged. Consequently, the washing efficiency is improved.
  • the dishwasher (1) comprises an additional straining member (17) which is provided between the filter group (7) and the circulation pump (9).
  • the additional straining member (17) retains the dirt particles passing through the filter group (7) before entering the circulation pump (9). Thus, possible malfunctions in the circulation pump (9) are prevented.
