- salt containers of the aforementioned type which have a cuboid cross section
- a different brine concentration is generated when using salt with different grain sizes.
- the difference in brine concentration is due to the fact that the fine-grained salt is difficult to penetrate with the amount of water required for brine formation is in contrast to filled-in coarse-grained salt, which is very well penetrated by the amount of water filled in, so that a very high brine concentration is achieved over the same duration of water exposure.
- a salt container with a cuboid cross-section is known, in which, in order to avoid the disadvantages described above, in addition to the usual essentially horizontal sieve, a lateral, substantially vertically extending sieve is attached between the salt collecting chamber and the brine collecting chamber, and in which the brine collecting space has been enlarged along the vertical sieve.
- the object of the invention is to provide a salt container for softening devices of household appliances, in particular dishwashers, in which a uniform brine concentration which is unaffected by the grain size of the salt added is produced in a simple manner.
- the object is achieved in the salt container according to the invention in that the salt receiving space of at least one at a flat angle to the horizontal extending partition is crossed, which is provided with at least one opening through which fine-grained salt can trickle through, but not coarse-grained salt, the water supply opening into a brine formation space formed between the partition and the sieve of the salt receiving space.
- an additional partition wall ensures in a simple manner that when fine-grain salt is poured in, this comes in a loose bed into an additionally created brine formation space between the partition wall and the sieve and can be dissolved there.
- coarse-grained salt When coarse-grained salt is poured in, this salt remains in the salt collecting area above the separating turn and is dissolved by the amount of water filled in.
- the brine formed from coarse-grained salt mixes with a remainder of the amount of water filled in, so that the brine concentration is lower, ie reduced to the brine concentration achieved with the fine-grained salt.
- the salt container known from the prior art, there is the possibility of filling in more salt than is advised to the user as appropriate by means of an instruction manual.
- the openings in the partition are advantageously designed as slots. This makes it possible to create openings over a greater width of the partition wall, which due to their shape nevertheless only allow fine grain salt to penetrate.
- the slot-shaped openings extend at least on one side of the salt container up to an inner surface of the side wall of the salt receiving space. This results in better pouring behavior with fine-grained salt and simple production.
- a maximum brine level is determined by an overflow edge of the brine outlet connection.
- the salt container is advantageously designed as a one-piece plastic part.
- the salt container is advantageously designed as a one-piece plastic part.
- a softening device for household appliances, in particular dishwashers consists of an ion exchanger (not shown) with the necessary supply and discharge lines and a salt container 1 which is filled with salt and into which a predetermined amount of water is introduced from a regeneration water storage container (not shown) to dissolve the salt.

- the salt receiving space 4 is separated by a sieve 6 from a brine collecting space 7, from which a brine outlet line 8 leading to the ion exchanger starts.
- the salt container 1 according to the invention is traversed by a partition 10 arranged at a flat angle ⁇ , which is provided at intervals with slot-shaped openings 11 through which fine-grained salt 5 can trickle, but coarse-grained salt (not shown) is not let through.
- a brine formation space 20 is formed, into which the water supply line 9 opens.
- the slot-shaped openings 11 are designed so that they start from the inner surface 12 of the side wall 13 of the salt receiving space.
- the salt container 1 according to the invention is filled with fine-grain salt 5. Due to the slightly oblique arrangement of the partition 10, the salt 5 is increasingly collected in the lower right area of the salt receiving space 4 in the drawing. Through the slit-shaped openings 11, the salt 5 reaches the brine formation space 20, that is to say in the direct vicinity of the water supply line 9. If water is supplied, brine formation therefore occurs very quickly and then flows through the sieve 6 into the brine collection space 7. This creates new space in the brine formation space 20, into which fine-grained salt 5 can enter again through the slot-shaped openings.
- the water introduced via the water supply line 9 naturally also passes through the slot-shaped openings 11 into the salt receiving space 4 and penetrates the fine-grained salt 5 - as far as possible - towards the filling opening 2 arranged above the salt collecting space 4.

Description
Die Erfindung betrifft einen Salzbehälter für Enthärtungseinrichtungen von Haushaltgeräten, insbesondere Geschirrspülmaschinen, mit einem eine Einfüllöffnung aufweisenden Salzaufnahmeraum, der durch Wenigstens ein Sieb von einem Solesammelraum getrennt ist, mit einer in den Salzaufnahmeraum einmündenden Wasserzulaufleitung und einer vom Solesammelraum zu einem Ionenaustauscher der Enthärtungseinrichtung führenden Soleauslaßleitung.The invention relates to a salt container for softening devices of household appliances, in particular dishwashers, with a salt receiving space having a filling opening, which is separated from a brine collecting space by at least one sieve, with a water supply line opening into the salt receiving space and a brine outlet line leading from the brine collecting space to an ion exchanger of the softening device.
Bei Salzbehältern der vorgenannten Art, die einen quaderförmigen Querschnitt aufweisen, wird bei Verwendung von Salz mit unterschiedlicher Körnung eine unterschiedliche Solekonzentration erzeugt. Zur automatischen Steuerung der Regenerierung eines Ionenaustauschers eines Haushaltgerätes ist es wünschenswert, unabhängig von der Körnung des eingefüllten Salzes in den Salzbehälter eine gleichmäßige Solekonzentration zu erzeugen. Die unterschiedliche Solekonzentration hat seine Ursache darin, daß das feinkörnige Salz von der zur Solebildung benötigten Wassermenge nur schwer durchdrungen wird im Gegensatz zu eingefülltem grobkörnigen Salz, das von der eingefüllten Wassermenge sehr gut durchdrungen wird, so daß über die gleiche Dauer der Wassereinwirkung eine sehr hohe Solekonzentration erzielt wird.In salt containers of the aforementioned type, which have a cuboid cross section, a different brine concentration is generated when using salt with different grain sizes. For the automatic control of the regeneration of an ion exchanger in a household appliance, it is desirable to generate a uniform brine concentration regardless of the grain size of the salt filled into the salt container. The difference in brine concentration is due to the fact that the fine-grained salt is difficult to penetrate with the amount of water required for brine formation is in contrast to filled-in coarse-grained salt, which is very well penetrated by the amount of water filled in, so that a very high brine concentration is achieved over the same duration of water exposure.
Aus der DE-A-35 22 901 ist ein Salzbehälter mit einem quaderförmigen Querschnitt bekannt, bei dem zur Vermeidung der vorbeschriebenen Nachteile zusätzlich zu dem üblichen im wesentlichen waagrecht verlaufenden Sieb zwischen dem Salzauffangraum und dem Solesammelraum ein seitliches im wesentlichen senkrecht verlaufendes Sieb angebracht ist und bei dem der Solesammelraum entlang des senkrechten Siebes vergrößert wurde. Dadurch wurde es möglich, daß bei Einfüllung feinkörnigen Salzes, bei der die eingefüllte Wassermenge nicht vollständig bis zu dem unteren Sieb durchdringt, die entstehende Salzsole seitlich austreten kann und in den Solesammelraum gelangt. Bei Einfüllung von grobkörnigen Salz entsteht durch das zusätzliche seitliche Austreten von Salzsole eine zu hohe Salzkonzentration, so daß diese Sole mit einer über eine Überlaufkante austretenden, zuviel eingefüllten Wassermenge mittels eines zusätzlichen Einganges in einen Regenerierwasserventil vermischt werden muß, um eine entsprechend niedrigere Salzkonzentration zu erreichen.From DE-A-35 22 901 a salt container with a cuboid cross-section is known, in which, in order to avoid the disadvantages described above, in addition to the usual essentially horizontal sieve, a lateral, substantially vertically extending sieve is attached between the salt collecting chamber and the brine collecting chamber, and in which the brine collecting space has been enlarged along the vertical sieve. This made it possible that when filling fine-grained salt, in which the amount of water not fully penetrated to the lower sieve, the resulting brine can escape laterally and enter the brine collection space. When coarse-grained salt is filled in, the additional salt escapes from the side to an excessively high salt concentration, so that this brine must be mixed with an excess amount of water coming out via an overflow edge by means of an additional inlet in a regeneration water valve in order to achieve a correspondingly lower salt concentration .
Aufgabe der Erfindung ist es, einen Salzbehälter für Enthärtungseinrichtungen von Haushaltgeräten, insbesondere Geschirspülmaschinen zu schaffen, in dem auf einfache Weise eine von der Körnung des eingefüllten Salzes unbeeinflußte, gleichmäßige Solekonzentration erzeugt wird.The object of the invention is to provide a salt container for softening devices of household appliances, in particular dishwashers, in which a uniform brine concentration which is unaffected by the grain size of the salt added is produced in a simple manner.
Die Aufgabe wird in dem erfindungsgemäßen Salzbehälter dadurch gelöst, daß der Salzaufnahmeraum von wenigstens einer unter einem flachen Winkel zur Waagrechten verlaufenden Trennwand durchzogen ist, die mit wenigstens einer Öffnung versehen ist, durch die feinkörniges Salz hindurchrieseln kann, grobkörniges Salz dagegen nicht, wobei die Wasserzuleitung in einen zwischen Trennwand und Sieb gebildeten Solebildungsraum des Salzaufnahmeraums einmündet.The object is achieved in the salt container according to the invention in that the salt receiving space of at least one at a flat angle to the horizontal extending partition is crossed, which is provided with at least one opening through which fine-grained salt can trickle through, but not coarse-grained salt, the water supply opening into a brine formation space formed between the partition and the sieve of the salt receiving space.
Durch die Anordnung einer zusätzlichen Trennwand wird auf einfache Weise erreicht, daß bei Einfüllung von feinkörnigem Salz dieses in einer losen Schüttung in einen zusätzlich geschaffenen Solebildungsraum zwischen der Trennwand und dem Sieb gelangt und dort aufgelöst werden kann. Bei Einfüllen von grobkörnigem Salz bleibt dieses Salz in dem Salzauffangraum oberhalb der Trennwend und wird durch die eingefüllte Wassermenge aufgelöst. In dem zusätzlich geschaffenen Solebildungsraum vermischt sich die aus grobkörnigem Salz gebildete Sole mit einem Rest der eingefüllten Wassermenge, so daß die Solekonzentration niedriger, d.h. auf die mit dem feinkörnigen Salz erzielte Solekonzentration reduziert wird. Bei dem aus dem Stand der Technik bekannten Salzbehälter besteht die Möglichkeit mehr Salz einzufüllen als dem Benutzer mittels einer Bedienungsanleitung als sachgemäß nahegelegt wird. Dabei kommt es, unabhängig von der Körnung des Salzes, zu einer höheren Solekonzentration als für die Regeneration des Ionenaustauschers notwendig ist. Dies führt zu einem unnötigen Salzverbrauch. Mit dem erfindungsgemäßen Salzbehälter wird dieser Nachteil größtenteils vermieden, da in dem zusätzlich geschaffenen Soleraum die durch die Öffnungen der Trennwand eintretende Sole einerseits bei grobkörnigem Salz mit weitgehend solefreiem Wasser und andererseits bei feinkörnigem Salz mit einer Sole mit jedenfalls für die Regeneration besser angepaßter Solekonzentration vermischt wird. Durch die Anordnung der Trennwand unter einem flachen Winkel wird gewährleistet, daß ein Nachrutschen des feinkörnigen Salzes nach dem Durchfallen der ersten Lage des feinkörnigen Salzes durch die Öffnungen der Trennwand gewährleistet ist. Die Anordnung der Wasserzulaufleitung in dem neu gebildeten Solebildungsraum verbessert die Durchdringung von in den Solebildungsraum einrieselndem feinkörnigem Salz und die Möglichkeit des Vermischens von Salzsole mit starker Konzentration bei Einfüllen von grobkörnigem Salz mit Wasser ohne Konzentration.The arrangement of an additional partition wall ensures in a simple manner that when fine-grain salt is poured in, this comes in a loose bed into an additionally created brine formation space between the partition wall and the sieve and can be dissolved there. When coarse-grained salt is poured in, this salt remains in the salt collecting area above the separating turn and is dissolved by the amount of water filled in. In the brine formation space additionally created, the brine formed from coarse-grained salt mixes with a remainder of the amount of water filled in, so that the brine concentration is lower, ie reduced to the brine concentration achieved with the fine-grained salt. In the case of the salt container known from the prior art, there is the possibility of filling in more salt than is advised to the user as appropriate by means of an instruction manual. Regardless of the grain size of the salt, this results in a higher brine concentration than is necessary for the regeneration of the ion exchanger. This leads to unnecessary salt consumption. This disadvantage is largely avoided with the salt container according to the invention, since in the brine space additionally created, the brine entering through the openings in the partition wall is mixed with coarse-grained salt on the one hand with largely brine-free water and on the other hand with fine-grained salt with a brine with brine concentration which is in any case better adapted for regeneration . The arrangement of the partition at a flat angle ensures that the fine-grained slides Salt is guaranteed after the first layer of fine-grained salt has fallen through the openings in the partition. The arrangement of the water supply line in the newly formed brine formation space improves the penetration of fine-grained salt trickling into the brine formation space and the possibility of mixing brine with a high concentration when filling coarse-grained salt with water without concentration.
Vorteilhafterweise sind die Öffnungen in der Trennwand als Schlitze ausgebildet. Damit ist es möglich, über eine größere Breite der Trennwand Öffnungen zu schaffen, die aufgrund ihrer Form trotzdem nur das Durchdringen von feinkörnigem Salz erlauben.The openings in the partition are advantageously designed as slots. This makes it possible to create openings over a greater width of the partition wall, which due to their shape nevertheless only allow fine grain salt to penetrate.
Nach einem weiteren Merkmal der Erfindung erstrecken sich die schlitzförmigen Öffnungen wenigstens auf einer Seite des Salzbehälters bis zu einer Innenfläche der Seitenwand des Salzaufnahmeraumes. Damit wird ein besseres Schüttverhalten bei feinkörnigem Salz und eine einfache Herstellung erreicht.According to a further feature of the invention, the slot-shaped openings extend at least on one side of the salt container up to an inner surface of the side wall of the salt receiving space. This results in better pouring behavior with fine-grained salt and simple production.
Nach einem weiteren Merkmal der Erfindung wird ein maximales Soleniveau durch eine Überlaufkante des Soleauslaßstutzens bestimmt.According to a further feature of the invention, a maximum brine level is determined by an overflow edge of the brine outlet connection.
Vorteilhafterweise ist der Salzbehälter mit Ausnahme eines Deckels und des Siebes als einstückiges Kunststoffteil ausgeführt. In den Zeichnungen wird ein Ausführungsbeispiel der Erfindung dargestellt.With the exception of a lid and the sieve, the salt container is advantageously designed as a one-piece plastic part. In the drawings, an embodiment of the invention is shown.

Eine Enthärtungseinrichtung von Haushaltgeräten, insbesondere Geschirrspülmaschinen besteht aus einem nicht dargestellten Ionenaustauscher mit der notwendigen Zu- und Ableitungen sowie einem Salzbehälter 1, der mit Salz befüllt wird und in den zum Auflösen des Salzes eine vorbestimmte Wassermenge aus einem nicht dargestellten Regenerierwasser-Vorratsbehälter eingeleitet wird. Die dabei entstehende Salzsole dient zur Regenerierung des Ionenaustauschers und wird diesem über ein nicht dargestelltes Regenerierventil zugeleitet. Der Salzbehälter 1 wird über eine Einfüllöffnung 2, die mit einem Deckel 3 verschlossen ist, mit Salz 5 befüllt und in einem Salzaufnahmeraum 4 gelagert. Der Salzaufnahmeraum 4 ist mittels eines Siebes 6 von einem Solesammelraum 7 getrennt, von dem eine zum Ionenaustauscher führende Soleauslaßleitung 8 ausgeht. Der erfindungsgemäße Salzbehälter 1 ist von einer unter einem flachen Winkel α angeordneten Trennwand 10 durchzogen, die in Abständen mit schlitzförmigen Öffnungen 11 versehen ist, durch die feinkörniges Salz 5 hindurchrieseln kann, nicht dargestelltes grobkörniges Salz aber nicht durchgelassen wird. Zwischen der Trennwand 10 und dem nur flüssigkeitsdurchlässigen Sieb 6 wird ein Solebildungsraum 20 gebildet, in den die Wasserzulaufleitung 9 einmündet. Die schlitzförmigen Öffnungen 11 sind so ausgestaltet, daß sie von der Innenfläche 12 der Seitenwand 13 des Salzaufnahmeraumes ausgehen.A softening device for household appliances, in particular dishwashers, consists of an ion exchanger (not shown) with the necessary supply and discharge lines and a salt container 1 which is filled with salt and into which a predetermined amount of water is introduced from a regeneration water storage container (not shown) to dissolve the salt. The resulting brine is used to regenerate the ion exchanger and is fed to it via a regeneration valve, not shown. The salt container 1 is filled with
Im folgenden wird die Funktionsweise beschrieben:
In Fig. 1 und 2 ist der erfindungsgemäße Salzbehälter 1 mit feinkörnigem Salz 5 befüllt. Durch die leicht schräge Anordnung der Trennwand 10 wird das Salz 5 verstärkt in dem in der Zeichnung rechten unteren Bereich des Salzaufnahmeraumes 4 gesammelt. Durch die schlitzförmigen Öffnungen 11 gelangt das Salz 5 in den Solebildungsraum 20, d.h. in direkte Nachbarschaft zu der Wasserzulaufleitung 9. Wenn Wasser zugeleitet wird kommt es daher sehr rasch zur Solebildung, die dann durch das Sieb 6 in den Solesammelraum 7 abfließt. Dadurch wird neuer Raum in dem Solebildungsraum 20 geschaffen, in den wieder durch die schlitzförmigen Öffnungen feinkörniges Salz 5 eintreten kann. Das über die Wasserzulaufleitung 9 eingeführte Wasser gelangt durch die schlitzförmigen Öffnungen 11 natürlich auch in den Salzaufnahmeraum 4 und durchdringt das feinkörnige Salz 5 - soweit möglich - in Richtung nach der oberhalb des Salzesammelraumes 4 angeordneten Einfüllöffnung 2. Hierbei wird ebenfalls Salzsole gebildet, die aus den schlitzförmigen Öffnungen 11 durch den Solebildungsraum 20 und durch das Sieb 6 in den Solesammelraum 7 geleitet wird.The mode of operation is described below:
1 and 2, the salt container 1 according to the invention is filled with fine-
Die vorgenannten Strömungen sind mittels Pfeilen 14 angedeutet. Ein maximales Soleniveau 15 ist durch eine Überlaufkante 16 in der Soleauslaßleitung 8, die zu einem Soleanschlußstutzen 17 führt, begrenzt.The aforementioned flows are indicated by
In dem nicht gezeigten Anwendungsfall der Befüllung des erfindungsgemäßen Salzbehälters 1 mit grobkörnigem Salz verbleibt aufgrund der Gestaltung der schlitzförmigen Öffnungen 11 das grobkörnige Salz überwiegend in dem Salzaufnahmeraum 4 oberhalb der Trennwand 10. Das über die Wasserzulaufleitung 9 eingeleitete Wasser gelangt über die schlitzförmigen Öffnungen 11 in den Salzaufnahmeraum 4 und durchdringt das grobkörnige Salz vollständig, so daß es zu einer vollständigen Auflösung des grobkörnigen Salzes mit einer hohen Solekonzentration kommt. Die Sole läuft durch die schlitzförmigen Öffnungen 11 zurück in den Solebildungsraum 20, der mit Wasser angefüllt ist. Dabei kommt es zu einer Vermischung von Sole mit hoher Konzentration mit Wasser, so daß die Salzkonzentration der durch das Sieb 6 in den Solesammelraum 7 gelangenden Sole niedriger ist als in dem Salzaufnahmeraum 4 und zwar in der gleichen Konzentration wie die vorbeschriebene entstandene Sole bei eingefülltem feinkörnigen Salz 5.In the application case (not shown) of filling the salt container 1 according to the invention with coarse-grained salt, due to the design of the slot-
Der Salzbehälter 1 mit Ausnahme des Deckels 3 und des Siebes 6 ist als einstückiges Kunststoffteil hergestellt.The salt container 1 with the exception of the
Mit der Erfindung ist auf einfache Art und Weise ein Salzbehälter 1 geschaffen, bei dem unabhängig von der Körnigkeit des eingefüllten Salzes eine Sole mit gleichmäßiger Konzentration zum Regenerieren des Ionenaustauschers entsteht.With the invention, a salt container 1 is created in a simple manner, in which, regardless of the granularity of the salt added, a brine is formed with a uniform concentration for regenerating the ion exchanger.
