Geschirrspülmaschine mit einem Filtersieb im SammeltopfDishwasher with a filter sieve in the collecting pot
Die Erfindung betrifft eine Geschirrspülmaschine mit einem Sammeltopf, je einem Anschlußstutzen für eine Umwälzpumpeund für eine Laugenpumpe und einem Filtersieb, welches den Sammeltopf in einen Ansaugraum für die Umwälzpumpe und ineinen Ansaugraum für die Laugenpumpe unterteilt.The invention relates to a dishwasher with a collecting pot, each with a connecting piece for a circulating pumpand for a drain pump and a filter screen, which the collecting pot in a suction space for the circulation pump and individed a suction space for the drain pump.
Derartige Geschirrspülmaschinen sind bekannt. Sie haben jedoch den Nachteil, daß das Spülergebnis sehr stark schwankt.Diese Schwankungen werden z.T. durch die Toleranzen an der Dichtungsstelle zwischen dem Filtersieb und dem Ansaugstutzender Laugenpumpe verursacht. Wenn der Spalt an dieser Stelle zu groß ist, werden von der Umwälzpumpe feine Schmutzteilchenaus dem Schmutzsammeiraum des AnschlußStutzens gesaugt. DieseSchmutzteilchen gelangen mit dem Spülwasser auf die Oberfläche des Geschirrs und können sich dort festsetzen. Ist der Spaltjedoch zu eng, so können die von der relativ starken Umwälzpumpe durch die Sieböffnungen gesaugten Schmutzteilchen vonder Laugenpumpe nicht mehr abgesaugt werden und lagern sich am Filtersieb ab. Beim nächsten Spülgang wird dieser Schmutzdann wieder von der Umwälzpumpe vom Filtersieb abgelöst und auf das Geschirr gesprüht.Such dishwashers are known. However, they have the disadvantage that the washing result fluctuates very strongly.These fluctuations are partly due to the tolerances at the sealing point between the filter screen and the intake portcaused by the drain pump. If the gap at this point is too large, the circulation pump will produce fine dirt particlessucked out of the dirt collecting space of the connection piece. TheseDirt particles get onto the surface of the dishes with the rinse water and can get stuck there. Is the gaptoo narrow, however, so the dirt particles sucked through the sieve openings by the relatively powerful circulation pump canthe drain pump can no longer be extracted and are deposited on the filter screen. The next time you rinse, this dirt becomesthen detached from the filter screen again by the circulation pump and sprayed onto the dishes.
Die Aufgabe der Erfindung ist, diese bekannten Nachteile zu vermeiden und eine Geschirrspülmaschine zu offenbaren, beiwelcher von der Umwälzpumpe kein Schmutz aus dem Schmutzsammeiraum gesaugt werden kann und bei der außerdem von derLaugenpumpe auch die Schmutzteilchen aus dem Ansaugraum der Umwälzpumpe abgesaugt werden können.The object of the invention is to avoid these known disadvantages and to disclose a dishwasherwhich no dirt can be sucked out of the dirt collection space by the circulation pump and also from theThe drain pump also allows the dirt particles to be sucked out of the suction chamber of the circulation pump.

Zu diesem Zweck ist die Erfindung dadurch gekennzeichnet, daß der Ansaugraum für die Umwälzpumpe und der Ansaugraum für dieLaugenpumpe über ein Ventil verbunden sind.For this purpose, the invention is characterized in that the suction space for the circulation pump and the suction space for theThe drain pump is connected via a valve.
Weitere Merkmale der Erfindung sind, daß das Ventil den Durchfluß von dem Ansaugraum der Umwälzpumpe zum Ansaugraum derLaugenpumpe erlaubt und den umgekehrten Durchfluß sperrt.Further features of the invention are that the valve controls the flow from the suction chamber of the circulation pump to the suction chamberDrain pump allowed and the reverse flow blocked.
Zwei Ausführungsbeispiele der Erfindung sind in den Zeichnungen schematisch dargestellt:Two embodiments of the invention are shown schematically in the drawings:
Es zeigen:Show it:
Fig. 1 den Sammeltopf einer Geschirrspülmaschine mit einem Ringventil, in Seitenansicht und im Schnitt,1 shows the collecting pot of a dishwasher with a ring valve, in side view and in section,
Fig. 2 den Sammeltopf mit einem Kugelventil, in Seitenansicht und im Schnitt.2 shows the collecting pot with a ball valve, in side view and in section.
Die nicht gezeichnete Geschirrspülmaschine besitzt einen Sammeltopf1. An dem Sammeltopf 1 ist je ein Anschlußstutzen 2 u. 3 .für eine Umwälzpumpe und für eine Laugenpumpe angeordnet. Außerdem sind Filtersiebe 4 u. 4' in dem Sammeltopf 1 vorhanden. DasFiltersieb 41 kann als Feinfilter ausgebildet sein, während dasFiltersieb 4 ein Feinstfilter sein kann. Durch das Filtersieb wird der Sammeltopf 1 in einem Ansaugraum 5 für die Umwälzpumpeund in einen Ansaugraum 6 für die Laugenpumpe unterteilt. Der Ansaugraum 5 ist mit dem Ansaugraum 6 über ein Ventil verbunden.Das Ventil erlaubt den Durchfluß von dem Ansaugraum 5 zu dem Ansaugraum 6 und sperrt den Durchfluß in umgekehrter Richtung.Das Ventil kann als Schwimmerventil ausgebildet sein. In der Fig. 1 ist das Schwimmerventil als Schwimm- ring 7 ausgebildet.In der Fig. 2 ist das Schwimmerventil als Schwimmerkugel 8 ausgebildet.The dishwasher, not shown, has a collecting pot 1. On the collecting pot 1 there is a connecting piece 2 and 3 each. arranged for a circulation pump and for a drain pump. In addition, there are filter sieves 4 and 4 'in the collecting pot 1. The filter screen 41 can be designed as a fine filter, while the filter screen 4 can be a fine filter. The collecting pot 1 is divided by the filter sieve into a suction space 5 for the circulation pump and into a suction space 6 for the drain pump. The suction space 5 is connected to the suction space 6 via a valve. The valve allows the flow from the suction chamber 5 to the suction chamber 6 and blocks the flow in the opposite direction. The valve can be designed as a float valve. In FIG. 1, the float valve is designed as a floating ring 7. In FIG. 2, the float valve is designed as a float ball 8.

Wenn die Umwälzpump« über den Anschlußstutzen 2 Spülflüssigkeitaus dem Sammeltopf 1 ansaugt, so kann die Spülflüssigkeitnur durch die Filtersiebe 4 u. 41 angesaugt werden. Ausdem Schmutzsammeiraum 9 kann kein Wasser angesaugt werden, da der Schwimmring 7 oder die Schwimmerkugel 8 die Verbindungsöffnungen 10 u. 11 verschließen. Besonders günstig ist es, wennder Schwimmring 7 oder die Schwimmerkugel 8 ein spezifisches Gewicht unter 1 besitzen.When the circulating pump sucks in rinsing liquid from the collecting pot 1 via the connecting piece 2, the rinsing liquid can only be sucked inthrough the filter sieves 4 and 4 1. No water can be sucked in from the dirt collecting space 9, since the floating ring 7 or the float ball 8 close the connection openings 10 and 11. It is particularly favorable if the swimming ring 7 or the float ball 8 have a specific weight of less than 1.
Wenn die Laugenpumpe über den Anschlußstutzen 3 die Spülflüssigkeitaus der Geschirrspülmaschine absaugt, so kann die Spülflüssigkeit aus dem Ansaugraum 5 durch die Verbindungsöffnungen 10 u. 11 abgesaugt werden, da der Schwimmring 7 unddie Schwimmerkugel 8 die Verbindungsöffnungen 10u. 11 freigeben. Der Ansaugraum 5 wird vollständig entleert. Schmutzreste könnendeshalb nicht zurückbleiben. Da kein Schmutzwasser von der Laugenpumpeaus dem Ansaugraum 5 durch das Filtersieb 4 gesaugt wird, kann sich auch an dem Filtersieb 4 kein Schmutz/ablagern . DasSpülergebnis ist also immer konstant. Es wird nicht von den Toleranzen an der Verbindungsstelle des Filtersiebs 4 mit dem Sammeltopf1 beeinflußt.When the drain pump via the connecting piece 3, the rinsing liquidsucks out of the dishwasher, the washing liquid can be sucked out of the suction space 5 through the connecting openings 10 and 11, since the floating ring 7 andthe float ball 8 the connection openings 10u. 11 release. The suction chamber 5 is completely emptied. Dirt residue cantherefore do not lag behind. Since no dirty water from the drain pumpis sucked out of the suction chamber 5 through the filter screen 4, no dirt / can deposit on the filter screen 4. ThatThe wash result is always constant. It does not depend on the tolerances at the connection point of the filter sieve 4 with the collecting pot1 affected.
Das Filtersieb 4 kann deshalb über eine Dichtung 12 oder über einen Konus mit dem Anschlußstutzen 13 der Laugenpumpe verbundensein.The filter screen 4 can therefore be connected to the connecting piece 13 of the drain pump via a seal 12 or via a conebe.
Der Schwimmring 7 kann auch mit dem ringförmigen Teil, welches die Verbindungsöffnungen 10 trägt, verschiebbar verbunden sein,so daß die gesamte Einheit mit dem Filtersieb 4 herausnehmbar ist.The floating ring 7 can also be slidably connected to the annular part which carries the connecting openings 10,so that the entire unit with the filter screen 4 can be removed.
