Die Erfindung betrifft eine Geschirrspülmaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a dishwasher according to the preamble of patent claim 1.

Eine bekannte, auf dem Markt befindliche Geschirrspülmaschine dieser Art weist einen lonenaustauscher auf, in dessen Frischwasserzulaufleitung in Fließrichtung des Wassers hinter einem vom Programmsteuergerät der Maschine gesteuerten Wassereinlaufventil eine freie Fließstrecke angeordnet und diese gemäß DE-C 3 239 226 ein durch Frischwasser füllbarer Speicherbehälter zugeordnet und in einer einstückigen Baueinheit zusammengefaßt ist. Zum Dosieren der Regeneriersolemenge weist der Speicherbehälter mehrere flüssigkeitsleitend verbundene Kammern auf, von denen eine Kammer an eine Ablaufleitung zur Salzvorratskammer angeschlossen ist. Die Salzvorratskammer steht durch eine ein Absperrventil aufweisende Soleleitung mit dem Ionenaustauscher in Verbindung. Die Salzvorratskammer ist neben dem Ionenaustauscher in der Maschine unterhalb des Speicherbehälters angeordnet, so daß bei über das Programmschaltwerk geöffnetem Absperrventil die Salzvorratskammer ausschließlich mit bevorratetem Wasser unter Schwerkraftwirkung aus dem Speicherbehälter gespeist wird. Zur Anpassung der zum Regenerieren der lonenaustauschermasse erforderlichen Solemenge an die Härte des Frischwassers am Aufstellort der Geschirrspülmaschine ist dem mehrkammrigen Speicherbehälter ein Wasserhärteschalter (DE-A 3 302 566 bzw. GB-A 2 133 975) zugeordnet, wobei die freie Fließstrecke, der Speicherbehälter mit einem Kondensationsschacht zu einer einstückigen Baueinheit integriert ist. Die Geschirrspülmaschine ist ferner mit einer Niveauregeleinrichtung (DE-GM 8 218 877) ausgerüstet, die ein durch eine Überlauftrennwand an den Spülbehälter bzw. dessen Ablaufwanne angeschlossenes Niveauregelgefäß aufweist und eine oder mehrere durch Saugheber entleerbare Überlaufkammer umfaßt und die mittels Fühler, bei Erreichen bestimmter Füllniveaus, den Wassereinlauf stoppt, indem das Wassereinlaufventil und/oder ein Sicherheitsventil (DE-PS 3 114 644) geschlossen wird.A known dishwashing machine of this type on the market has an ion exchanger, in the fresh water supply line of which a free flow path is arranged behind a water inlet valve controlled by the program control unit of the machine and which, according to DE-C 3 239 226, is assigned a storage tank which can be filled with fresh water and is summarized in a one-piece unit. To meter the amount of regeneration brine, the storage container has a number of chambers connected in a liquid-conducting manner, one chamber of which is connected to an outlet line to the salt storage chamber. The salt storage chamber is connected to the ion exchanger by a brine line with a shut-off valve. The salt storage chamber is arranged next to the ion exchanger in the machine below the storage container, so that when the shut-off valve is opened via the program switch, the salt storage chamber is fed exclusively with stored water under the effect of gravity from the storage container. In order to adapt the amount of brine required to regenerate the ion exchange mass to the hardness of the fresh water at the installation site of the dishwasher, a water hardness switch (DE-A 3 302 566 or GB-A 2 133 975) is assigned to the multi-chamber storage tank, with the free flow path, the storage tank a condensation shaft is integrated into a one-piece unit. The dishwasher is also equipped with a level control device (DE-GM 8 218 877), which has a level control vessel connected to the washing container or its drain pan through an overflow partition and comprises one or more overflow chambers which can be emptied by suction lifters and which by means of sensors when certain filling levels are reached stops the water inlet by closing the water inlet valve and / or a safety valve (DE-PS 3 114 644).

Der Erfindung liegt die Aufgabe zugrunde, eine Geschirrspülmaschine der eingangs genannten Art so zu gestalten, daß der Aufwand für die Herstellung und Montage vermindert und die Maschine gegen Undichtheiten in den Flüssigkeitsführungen sicherer wird.The invention has for its object to design a dishwasher of the type mentioned so that the effort for manufacture and assembly is reduced and the machine against leaks in the liquid guides is safer.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichneten Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 bis 7 gekennzeichnet.This object is achieved by the features characterized in claim 1. Advantageous embodiments of the invention are characterized in claims 2 to 7.

Die erfindungsgemäß ausgestaltete Geschirrspülmaschine hat den Vorteil, daß dem Spülbehälter und der bodenseitigen Ablaufwanne die Behältereinheit aus Kunststoff nebengeordnet wird, die einen Frischwasseranschluß mit freier Fließstrecke, eine Kanalverbindung zu einer aus lonenaustauschermasse aufnehmenden lonenaustauscherkammer, einen Speicherbehälter zur Abgabe wählbarer Wasservolumen, eine Ablaufleitung vom Speicherbehälter zu einer Salzvorratskammer sowie eine Soleleitung zum Ionenaustauscher aufweist und über einen Auslaß der lonenaustauscherkammer mit dem Spülbehälter bzw. dessen Ablaufwanne verbunden ist.The dishwasher designed in accordance with the invention has the advantage that the container unit made of plastic is arranged next to the washing container and the bottom drain pan, which has a fresh water connection with a free flow path, a channel connection to an ion exchange chamber receiving ion exchange mass, a storage container for dispensing selectable water volumes, and a drain line from the storage container has a salt storage chamber and a brine line to the ion exchanger and is connected via an outlet of the ion exchange chamber to the rinsing container or its drain pan.

Zur Vermeidung vieler Einzelaggregate mit Anschlußleitungen ist in die Baueinheit aus Kunststoff auch das auf Normal- und Sicherheitsniveau und/oder ein Überlaufniveau des Spülbehälters ansprechende Niveauregelgefäß integriert, das über die Verbindung der Behältereinheit nach Art einer kommunizierenden Röhre mit der Ablaufwanne des Spülbehälters verbunden ist.To avoid many individual units with connecting lines, the level control vessel, which responds to normal and safety levels and / or an overflow level of the rinsing tank, is integrated into the plastic unit and is connected to the drain pan of the rinsing tank via the connection of the tank unit in the manner of a communicating tube.

Anhand der Zeichnung wird ein Ausführungsbeispiel der schematisch dargestellten Behältereinheit einer erfindungsgemäßen Geschirrspülmaschine näher erläutert.An exemplary embodiment of the schematically illustrated container unit of a dishwasher according to the invention is explained in more detail with reference to the drawing.

Die neben einer Seitenwand eines nicht gezeichneten Spülbehälters einer Geschirrspülmaschine angeordnete, aus Kunststoff bestehende Behältereinheit 1 enthält im Bodenbereich einen lonenaustauscher 2, dessen lonenaustauschermasse sich in einer Kammer der Behältereinheit zwischen Siebwänden 3, 4 befindet. Über dem Ionenaustauscher weist die Behältereinheit eine Salzvorratskammer 5 auf, die durch einen, durch die Spülbehälterseitenwand in den Spülraum geführten und durch einen Deckel oder dergleichen verschließbaren Einfüllstutzen 6 mit Salz auffüllbar ist. Von der Salzvorratskammer 5 führt eine Soleleitung 7 zum lonenaustauscher 2. Oberhalb der Salzvorratskammer bildet die Behältereinheit 1 einen mehrkammerigen Speicherbehälter 8, dessen Kammern mit einer Verteilerkammer 9 strömungsverbunden sind. In der Verteilerkammer 9 ist ein Stellelemenl 10 vorgesehen, das einen Wasserhärteschalter bildet. In Abhängigkeit von der Härte des Frischwassers am Aufstellort der Geschirrspülmaschine wird das Stellelement in eine bestimmte Lage gebracht. Hiermit ist es möglich, die dem Ionenaustauscher zur Regenerierung seiner Füllung aus der Salzvorratskammer zuzuführende Solemenge dadurch zu bemessen, daß der Salzvorratskammer aus dem Speicherbehälter lediglich der Wasservorrat einer Kammer oder der Wasservorrat aus mehreren Kammern zugeführt wird.The plastic container unit 1 arranged next to a side wall of a dishwashing container of a dishwasher, not shown, contains an ion exchanger 2 in the bottom area, the ion exchanger mass of which is located in a chamber of the container unit between sieve walls 3, 4. Above the ion exchanger, the container unit has a salt storage chamber 5, which can be filled with salt through a filler neck 6, which is led through the side wall of the washing container and can be closed by a cover or the like. A brine line 7 leads from the salt storage chamber 5 to the ion exchanger 2. Above the salt storage chamber, the container unit 1 forms a multi-chamber storage container 8, the chambers of which are flow-connected to a distributor chamber 9. A control element 10 is provided in the distribution chamber 9 and forms a water hardness switch. Depending on the hardness of the fresh water at the installation site of the dishwasher, the control element is brought into a certain position. This makes it possible to measure the amount of brine to be supplied to the ion exchanger to regenerate its filling from the salt storage chamber by supplying the salt storage chamber from the storage container with only the water supply from one chamber or the water supply from several chambers.

Die Behältereinheit 1 ist über einen Frischwasser-Anschlußstutzen 11 hinter einem nicht gezeichneten Wassereinlauf- und/oder Sicherheitsventil an die Frischwasserzuleitung der Geschirrspülmaschine angeschlossen. Vom Frischwasser-Anschlußstutzen 11 führt ein Frischwasserkanal 12 der Behältereinheit 1 zu einer ebenfalls in die Behältereinheit integrierten freien Fließstrecke 13. Hinter der freien Fließstrecke 13 führt eine Fortsetzung 14 des Frischwasserkanals zum Ionenaustauscher 2. Ein Auslaß 15 der lonenaustauschkammer 2 ist an den Spülbehälter bzw. an dessen Ablaufwanne angeschlossen.The container unit 1 is connected to the fresh water supply line of the dishwasher via a fresh water connecting piece 11 behind a water inlet and / or safety valve (not shown). From the fresh water connection piece 11, a fresh water channel 12 of the container unit 1 leads to a free flow path 13 which is also integrated into the container unit. Behind the free flow path 13, a continuation 14 of the fresh water channel leads to the ion exchanger 2. An outlet 15 of the ion exchange chamber 2 is connected to the washing container or connected to its drain pan.

Neben dem bodenseitig in der Behältereinheit 1 untergebrachten Ionenaustauscher 2 befindet sich ferner ein Niveauregelgefäß 16. Das Niveauregelgefäß 16 ist über eine Bodenöffnung 17 und den Auslaß 15 als kommunizierende Röhre mit der Ablaufwanne bzw. dem Spülbehälter verbunden. Eine erste Überlauftrennwand 18 im Niveauregelgefäß liegt mit ihrer Überlaufkante in Höhe des normalen Füllniveaus 19 des Spülbehälters. Wird dieser Wasserstand im Spülbehälter erreicht, so genügt eine geringe, über die Überlauftrennwand 18 in eine erste Kammer 20 überschwappende Wassermenge um einen darin vorgesehenen Schwimmer 21 soweit anzuheben, daß dieser einen Schalter 22 zum Schließen des Wassereinlaufventils betätigt. Wird durch Einschalten der Entleerungspumpe der Spülbehälter entleert, so fällt mit dem Wasserstand im Spülbehälter gleichzeitig der Wasserstand im Niveauregelgefäß ab, ein Saugheber 23 springt an und entleert die Kammer 20.In addition to the ion exchanger 2 accommodated in the bottom of the container unit 1, there is also a level control vessel 16. The level control vessel 16 is via a bottom opening 17 and the outlet 15 as a communicating tube with the Ab trough or the rinsing container connected. A first overflow partition 18 in the level control vessel lies with its overflow edge at the level of the normal filling level 19 of the washing container. If this water level in the rinsing tank is reached, a small amount of water spilling over the overflow partition 18 into a first chamber 20 is sufficient to raise a float 21 provided therein that it actuates a switch 22 to close the water inlet valve. If the rinsing tank is emptied by switching on the emptying pump, the water level in the level control vessel falls simultaneously with the water level in the rinsing tank, a siphon 23 starts and empties the chamber 20.

Zum Überwachen eines Sicherheitsniveaus 24 ist im Niveauregelgefäß 16 vor einer zweiten, eine Luftfallenkammer bildenden Kammer 25 eine bis in die Höhe des Sicherheitsniveaus hochgezogene zweite Überlauftrennwand 26 vorgesehen. An die Luftfallenkammer ist über eine Leitungsverbindung 27 ein nicht dargestellter Druckwächter oder eine Druckdose eines Sicherheitsventils angeschlossen. Zum Entleeren der zweiten Kammer dient ein zweiter Saugheber 28.To monitor a safety level 24, a second overflow partition 26 is provided in the level control vessel 16 in front of a second chamber 25 forming an air trap chamber up to the level of the safety level. A pressure switch (not shown) or a pressure cell of a safety valve is connected to the air trap chamber via a line connection 27. A second siphon 28 is used to empty the second chamber.

Gegenüber dem Auslaß der Soleleitung 7 aus der Salzvorratskammer 5 weist die Salzvorratskammer ein Bodensieb 29 und ein Seitenwandsieb 30 auf. Neben dem Seitenwandsieb 30 ist eine mit der Salzvorratskammer strömungsverbundene Röhre 31 oder dergleichen ausgebildet, in der ein Schwimmer 32 zur Salzmangelanzeige vorgesehen ist. Im Bereich des Einfüllstutzens 6 der Salzvorratskammer 5 zweigt ein Überlaufkanal 33 zum lonenaustauscher 2 ab. Wird die Salzvorratskammer mit Salz aufgefüllt, so gelangt die verdrängte, überschüssige Salzsole durch den Überlaufkanal 33 in den lonenaustauscher und es wird verhindert, daß die Salzsole ungenutzt und unerwünscht in den Spülbehälter überläuft. Mit 34 ist ein Kanal zur Belüftung der Soleleitung 7 bezeichnet.Opposite the outlet of the brine line 7 from the salt storage chamber 5, the salt storage chamber has a bottom sieve 29 and a side wall sieve 30. In addition to the side wall screen 30, a tube 31 or the like which is connected to the flow with the salt storage chamber and in which a float 32 is provided for indicating the lack of salt is provided. In the area of the filler neck 6 of the salt storage chamber 5, an overflow channel 33 branches off to the ion exchanger 2. If the salt storage chamber is filled with salt, the displaced, excess brine passes through the overflow channel 33 into the ion exchanger and it is prevented that the brine is not used and undesirably overflows into the rinsing container. 34 with a channel for ventilation of the brine line 7 is designated.

Im oberen Bereich, neben dem Speicherbehälter 8, umfaßt die Behältereinheit 1 eine Kondensationskammer 35 mit darin angeordneten Leitstegen 36. Die Kondensationskammer 35 ist über eine Ausgleichsöffnung 37 mit dem Spülbehälter verbunden. Aus dem Spülbehälter austretende Wrasen werden in der Kondensationskammer 35 niedergeschlagen. Ferner weist die Behältereinheit über der Kondensationskammer eine Belüftungsöffnung 38 auf, zu der ein Luftkanal zur freien Fließstrecke 13 sowie zur Kondensationskammer 35 besteht.In the upper area, next to the storage container 8, the container unit 1 comprises a condensation chamber 35 with guide webs 36 arranged therein. The condensation chamber 35 is connected to the flushing container via a compensating opening 37. Vapors emerging from the rinsing container are precipitated in the condensation chamber 35. Furthermore, the container unit has a ventilation opening 38 above the condensation chamber, to which there is an air channel to the free flow path 13 and to the condensation chamber 35.

In der Kanalverbindung 39 zwischen dem Speicherbehälter 8 und der Salzvorratskammer 5 sowie in der Soleleitung 7 zum Ionenaustauscher ist ein vom Programmschaltwerk der Geschirrspülmaschine steuerbares Ventil 40 in einem Ventilgehäuse 41 der Behältereinheit angeordnet.In the channel connection 39 between the storage container 8 and the salt storage chamber 5 and in the brine line 7 to the ion exchanger, a valve 40 which can be controlled by the program switch of the dishwasher is arranged in a valve housing 41 of the container unit.

Der Speicherbehälter 8 ist durch Leckwasser aus der freien Fließstrecke 13 füllbar. Bei Überfüllung des Speicherbehälters wird das überschüssige Wasser über die Kondensationskammer 35 und die Ausgleichsöffnung 37 in den Spülbehälter geleitet.The storage container 8 can be filled by leakage water from the free flow path 13. If the storage tank is overfilled, the excess water is passed through the condensation chamber 35 and the compensation opening 37 into the rinsing tank.
