Description
Die Erfindung betrifft einen Geschirrspülautomaten, insbesondere einen Geschirrspülautomaten zur Verwendung im Haushalt, mit einem einen Spülraum bereitstellenden Spülbehälter, der eine mittels einer verschwenkbar gelagerten Spülraumtür verschließbare Beschickungsöffnung aufweist, und mit einem Vorratsbehälter für die Zwischenspeicherung von Spülflotte.The invention relates to an automatic dishwasher, in particular a dishwasher for use in the home, with a rinsing container providing a rinsing container, which has a closable by means of a pivotally mounted Spülraumtür feed opening, and with a reservoir for the intermediate storage of rinsing liquor.
Geschirrspülautomaten der eingangs genannten Art sind aus dem Stand der Technik gut bekannt. Sie verfügen über einen einen Spülraum bereitstellenden Spülbehälter, der im bestimmungsgemäßen Verwendungsfall der Aufnahme von zu reinigendem Spülgut dient. Zur Beschickung des Spülbehälters dient eine Beschickungsöffnung, die mittels einer verschwenkbar gelagerten Spülraumtür fluiddicht verschließbar ist.Dishwashers of the type mentioned are well known in the art. They have a rinsing container which provides a rinsing container which, in the intended use, serves to receive items to be cleaned. To feed the washing container is a feed opening, which is closed fluid-tight by means of a pivotally mounted dish door.
Für eine Beaufschlagung von zu reinigendem Spülgut mit Spülflotte dienen innerhalb des Spülbehälters verdrehbar angeordnete Sprüharme. Diese werden über eine Umwälzpumpe mit Spülflotte versorgt. Je nach Ausgestaltung des Geschirrspülautomaten sind bevorzugterweise zwei oder drei Sprüharme vorgesehen.For loading of items to be cleaned with rinse liquor within the rinsing container rotatably arranged spray arms. These are supplied with rinsing fluid via a circulation pump. Depending on the configuration of the dishwasher, preferably two or three spray arms are provided.
Aus dem Stand der Technik ist es ferner bekannt, Geschirrspülautomaten der eingangs genannten Art zum Zwecke der Wassereinsparung mit einem Vorratsbehälter zur Zwischenspeicherung von Spülflotte auszurüsten. Dieser Vorratsbehälter dient dazu, am Ende eines bestimmungsgemäßen Programmablaufes im Spülbehälter noch befindliche Restspülflotte aufzunehmen und bis zum Beginn eines nächsten Spülprogramms zu bevorraten. Typischerweise wird die zum Ende eines Spülprogramms verhältnismäßig saubere Klarspülflotte zur Zwischenspeicherung genutzt. Mit Beginn eines neuen Spülprogramms wird die zwischengespeicherte Spülflotte in den Spülbehälter abgelassen, so dass eine um die Menge an zurückgeführter Spülflotte reduzierte Menge an Frischwasser für den Beginn des neuen Spülprogramms erforderlich ist.From the prior art, it is also known to equip automatic dishwashers of the type mentioned for the purpose of saving water with a reservoir for intermediate storage of rinsing liquor. This reservoir is used to record at the end of a proper program flow in the washing still residual scouring liquor and to stockpile until the beginning of a next wash program. Typically, at the end of a wash program, relatively clean rinse liquor is used for intermediate storage. With the beginning of a new washing program, the cached rinse liquor is drained into the rinse tank, so that a reduced amount of fresh water for the start of the new rinse program is required by the amount of rinse liquor returned.
Die innerhalb des Vorratsbehälters zwischengespeicherte Spülflotte unterliegt der Verkeimung. Diese ergibt sich häufig einhergehend mit einer Geruchsbelästigung. Um dem entgegenzuwirken, sind aus dem Stand der Technik zahlreiche unterschiedliche Maßnahmen bekannt geworden. So ist zum Beispiel vorgeschlagen worden, in die strömungstechnische Verbindung zwischen Spülbehälter und Vorratsbehälter einen Filter einzusetzen. Dabei ist es Sinn und Zweck eines solchen Filters, in der Spülflotte befindliche Partikel, Verunreinigungen, Verschmutzungen und/oder dergleichen herauszufiltern, bevor die Spülflotte zwecks Zwischenspeicherung in den Vorratsbehälter überführt wird.The rinsing fluid cached within the storage container is subject to contamination. This often results in conjunction with an odor nuisance. To counteract this, there are many different ones from the prior art Measures become known. For example, it has been proposed to use a filter in the fluidic connection between the washing container and the reservoir. It is the purpose of such a filter to filter out particles, impurities, contaminants and / or the like present in the wash liquor, before the wash liquor is transferred into the storage container for intermediate storage.
Obgleich sich der Einsatz eines Filters zur Reinigung der Spülflotte dem Grunde nach bewährt hat, bestehen gewisse Nachteile, insbesondere in der Handhabung. So setzt sich das Filtergewebe mit fortgesetzter Anwendungsdauer nach und nach zu. Um weiterhin eine bestimmungsgemäße Funktionstüchtigkeit gewährleisten zu können, ist eine Reinigung des Filters erforderlich. Dies wird verwenderseitig als lästig empfunden, weshalb es regelmäßig mit der Folge unterbleibt, dass der Vorratsbehälter wegen Verstopfens des Filters nicht in dem möglichen Maße mit Spülflotte zum Zwecke der Zwischenspeicherung aufgefüllt wird.Although the use of a filter for purifying the rinsing liquor has basically proved successful, there are certain disadvantages, in particular in handling. Thus, the filter fabric is gradually increasing with continued use time. In order to continue to ensure proper functioning, a cleaning of the filter is required. This is perceived by the user as annoying, which is why it regularly fails with the result that the reservoir is not filled due to clogging of the filter to the extent possible with rinsing liquor for the purpose of caching.
Ausgehend vom Vorbeschriebenen ist es die Aufgabe der Erfindung, einen Geschirrspülautomaten der eingangs genannten Art vorzuschlagen, der eine insgesamt vereinfachte Handhabung ermöglicht.Based on the above, it is the object of the invention to propose a dishwasher of the type mentioned, which allows a total of simplified handling.
Zur Lösung dieser Aufgabe wird mit der Erfindung ein Geschirrspülautomat der eingangs genannten Art vorgeschlagen, der sich auszeichnet durch eine in die strömungstechnische Verbindung zwischen Spülbehälter und Vorratsbehälter eingesetzten Keimungseinrichtung, wobei die Entkeimungseinrichtung ein Gehäuse, eine darin angeordnete UV-Lampe sowie einen mit der UV-Lampe und dem Gehäuse zusammenwirkenden Abstreifer aufweist, wobei der Abstreifer im Gehäuse verschieblich gelagert ist.To solve this problem, a dishwashing machine of the type mentioned above is proposed with the invention, which is characterized by a germinating device used in the fluidic connection between washing container and reservoir, wherein the sterilizing device comprises a housing, a UV lamp arranged therein and a with the UV Lamp and the housing has cooperating scraper, wherein the scraper is slidably mounted in the housing.
Der mit der Erfindung vorgeschlagene Geschirrspülautomat verfügt über eine Entkeimungseinrichtung. Diese Entkeimungseinrichtung wird von der Spülflotte vor einem Einströmen in den Vorratsbehälter passiert, wodurch es zu einer Entkeimung derselben kommt. Zur Zwischenspeicherung in den Vorratsbehälter gelangt mithin entkeimte Spülflotte.The dishwashing machine proposed by the invention has a sterilizing device. This sterilization device is passed by the rinsing liquor before it flows into the reservoir, whereby it comes to a sterilization of the same. For intermediate storage in the reservoir thus sterilized rinse liquor.
Die Entkeimungseinrichtung verfügt über ein Gehäuse. Innerhalb des Gehäuses ist eine UV-Lampe angeordnet bei der UV-Lampe handelt es sich bevorzugterweise um eine UVC-Lampe, das heißt um eine Lampe, die Licht im ultravioletten Spektrum im Wellenlängenbereich zwischen 280 nm und 200 nm abgibt.The degerminator has a housing. Within the housing, a UV lamp is arranged in the UV lamp is preferably a UVC lamp, that is, a lamp that emits light in the ultraviolet spectrum in the wavelength range between 280 nm and 200 nm.
Die UV-Lampe stellt das Herzstück der Entkeimungseinrichtung dar. Sie wird im Falle der bestimmungsgemäßen Beaufschlagung mit Spülflotte, das heißt im Falle der Überführung von Spülflotte aus dem Spülbehälter in den Vorratsbehälter eingeschaltet. Die von ihr abgegebene Strahlung wirkt auf die in die Entkeimungseinrichtung eingeführte Spülflotte ein, infolge dessen es zu einer Inaktivierung, das heißt Abtötung von Bakterien, Keimen und/oder dergleichen biologischen Substanzen kommt. Im Ergebnis der Vorbeiführung der Spülflotte an der UV-Lampe der Entkeimungseinrichtung ist die Spülflotte entkeimt, so dass es zur Zwischenspeicherung von entkeimter Spülflotte im Vorratsbehälter kommt.The UV lamp is the heart of the sterilization device. It is in the case of the intended admission with rinsing liquor, that is turned on in the case of transfer of rinsing water from the washing container into the reservoir. The radiation emitted by it acts on the rinsing liquor introduced into the sterilization device, as a result of which an inactivation, that is to say the killing of bacteria, germs and / or similar biological substances, occurs. As a result of the passage of the rinse liquor to the UV lamp of the sterilization device, the rinsing liquor is sterilized, so that it comes to the temporary storage of sterilized rinsing liquor in the reservoir.
Infolge des Hindurchführens von zu entkeimender Spülflotte durch die Entkeimungseinrichtung kann es am Gehäuse der Entkeimungseinrichtung und/oder an der UV-Lampe zu Ablagerungen von aus der Spülflotte stammenden Partikeln, Verunreinigungen, Verschmutzungen und/oder dergleichen kommen. Insbesondere etwaige Ablagerungen an der UV-Lampe können die bestimmungsgemäße Funktionsweise der Entkeimungseinrichtung stören, da im bestimmungsgemäßen Verwendungsfall von der UV-Lampe abgegebene Strahlung nicht mehr in vollem Umfang die zu entkeimende Spülflotte erreichen kann.As a result of passing the rinsing liquor to be sterilized through the degerming device, deposits of impurities, contaminants and / or the like originating from the rinsing liquor can occur on the housing of the sterilizing device and / or on the UV lamp. In particular, any deposits on the UV lamp can interfere with the intended operation of the sterilization device, as in the intended use of radiation emitted by the UV lamp radiation can not fully reach the rinsing water to be sterilized.
Um einer Verunreinigung der Entkeimungseinrichtung vorzubeugen, ist diese mit einem Abstreifer ausgerüstet, der mit der UV-Lampe einerseits und dem Gehäuse andererseits zusammenwirkt. Der Abstreifer ist im Gehäuse verschieblich geführt, so dass er im Falle einer bestimmungsgemäßen Verschiebebewegung insbesondere an der UV-Lampe entlangfährt und dabei etwaige Ablagerungen von Partikeln, Verunreinigungen, Verschmutzungen und/oder dergleichen abstreift. In einer Rückspülung können diese durch den Abstreifer entfernten Ablagerungen zurück in den Spülraum befördert werden, von wo aus sie durch Abpumpen entsorgt werden können. Dabei erfolgt ein solches Abpumpen bevorzugterweise während einer nachfolgenden bestimmungsgemäßen Programmdurchführung.To prevent contamination of the sterilization device, this is equipped with a scraper, which cooperates with the UV lamp on the one hand and the housing on the other. The scraper is guided displaceably in the housing, so that in the case of an intended displacement movement, in particular, it travels along the UV lamp and strips off any deposits of particles, contaminants, dirt and / or the like. In a backwash, these deposits removed by the scraper can be transported back into the washing room, from where they can be disposed of by pumping. In this case, such pumping preferably takes place during a subsequent intended program execution.
Die nach der Erfindung vorgesehene Entkeimungseinrichtung ist selbstreinigend. Der im Gehäuse der Entkeimungseinrichtung geführte Abstreifer sorgt dafür, dass sich in der Entkeimungseinrichtung insbesondere an der UV-Lampe ausbildende Ablagerungen entfernt werden, so dass eine Rückführung derselben in den Spülbehälter gestattet ist. Ein Zusetzen der Entkeimungseinrichtung ist damit unterbunden. Eine vom Verwender durchzuführende manuelle Reinigung ist in vorteilhafter Weise nicht erforderlich.The provided according to the invention sterilizing device is self-cleaning. The scraper guided in the housing of the sterilizing device ensures that deposits forming in the sterilizing device, in particular on the UV lamp, are removed, so that a return of the same into the washing container is permitted. Clogging of the sterilization device is thus prevented. A manual cleaning to be performed by the user is advantageously not required.
Im bestimmungsgemäßen Verwendungsfall erfolgt über die erfindungsgemäß vorgesehene Entkeimungseinrichtung eine Entkeimung der dem Vorratsbehälter zuzuführende Spülflotte. Zur Zwischenspeicherung im Vorratsbehälter gelangt mithin entkeimte Spülflotte, so dass die Gefahr von Verkeimungen im Vorratsbehälter und die damit einhergehende Gefahr von Geruchsbelästigungen minimiert ist. Bei einer Rückführung der Spülflotte in den Spülbehälter erfolgt eine Rückspülung der Entkeimungseinrichtung, so dass sich unter Umständen zuvor in der Entkeimungseinrichtung ausgebildete Ablagerungen in den Spülbehälter strömen, wo es dann im Zuge einer bestimmungsgemäßen Programmdurchführung zu einer Entsorgung derselben kommt. Dabei sorgt der erfindungsgemäß vorgesehene Abstreifer dafür, dass eine Reinigung der Entkeimungseinrichtung durchgeführt wird, so dass eine verwenderseitige manuelle Reinigung nicht von Nöten ist.In the intended use case, a sterilization of the rinsing liquor to be supplied to the storage container takes place via the sterilization device provided according to the invention. For intermediate storage in the reservoir thus sterilized rinse liquor, so that the risk of microbial contamination in the reservoir and the associated risk of odor nuisance is minimized. When the rinsing liquor is returned to the rinsing container, the sterilizing device is backwashed, so that deposits previously formed in the sterilizing device may flow into the rinsing container, where it will then be disposed of in the course of a proper program execution. In this case, the scraper provided according to the invention ensures that a cleaning of the sterilization device is carried out, so that a user-side manual cleaning is not necessary.
Gemäß einem besonderen Vorschlag der Erfindung ist vorgesehen, dass die Entkeimungseinrichtung einen mit dem Abstreifer zusammenwirkenden Mitnehmer aufweist, der außenseitig des Gehäuses an diesem verschieblich angeordnet ist. Dabei weist der Abstreifer und/oder der Mitnehmer einen Magneten auf und/oder der Abstreifer beziehungsweise der Mitnehmer sind zumindest teilweise als Magnet ausgebildet. Bei einer Verfahrbewegung des Mitnehmers kommt es aufgrund der zwischen dem Mitnehmer und dem Abstreifer wirkenden magnetischen Kraft zu einer Verfahrbewegung auch des Abstreifers. Der Abstreifer folgt in seiner Bewegung mithin der durch den Mitnehmer vorgegebenen Bewegung.According to a particular proposal of the invention it is provided that the sterilizing device has a cooperating with the scraper driver, which is arranged on the outside of the housing on this displaceable. In this case, the scraper and / or the driver on a magnet and / or the scraper or the driver are at least partially formed as a magnet.

The wiper thus follows in its movement of the predetermined by the driver movement.
Der Mitnehmer ist mechanisch mit der Spülraumtür gekoppelt, zu welchem Zweck bevorzugterweise ein Bowdenzug vorgesehen ist. Bei einer Verschwenkbewegung der Spülraumtür kommt es so zu einer Verfahrbewegung des über den Bowdenzug mit der Spülraumtür gekoppelten Mitnehmers. Dieser wirkt wiederum magnetische mit dem Abstreifer zusammen, so dass es infolge einer Bewegung der Spülraumtür im Ergebnis zu einer Verfahrbewegung des mit insbesondere der UV-Lampe zusammenwirkenden Abstreifers kommt. Bei jeder verwenderseitigen Betätigung der Spülraumtür kommt es damit zu einer Verfahrbewegung des Abstreifers und damit zu einer Entfernung von etwaigen Ablagerungen am Gehäuse und/oder der UV-Lampe der Entkeimungseinrichtung.The driver is mechanically coupled to the Spülraumtür, for which purpose preferably a Bowden cable is provided. In a pivoting movement of the Spülraumtür it comes so to a movement of coupled via the Bowden cable with the Spülraumtür driver. This in turn interacts magnetically with the scraper, resulting in a result of a movement of the Spülraumtür in the result a movement of the cooperating with particular UV lamp scraper comes. Each user-side actuation of the Spülraumtür it comes with it to a movement of the scraper and thus to a removal of any deposits on the housing and / or the UV lamp of the sterilization device.

This hollow cylinder is inserted while leaving an annular gap in the housing of the sterilization device. This hollow cylinder serves to protect the UV lamp and is formed from a material permeable to the radiation emitted by the UV lamp. A direct contact of the rinsing liquor with the UV lamp does not take place according to this embodiment. The rinsing fluid flows on the outside of the UV lamp receiving hollow cylinder along.
Der Abstreifer ist gemäß einem weiteren Merkmal der Erfindung ringförmig ausgebildet und innerhalb des ringförmigen Spaltraums zwischen Gehäuse einerseits und Hohlzylinder andererseits angeordnet. Innerhalb dieses Ringspalts kann der Abstreifer in Höhenrichtung des Gehäuses verfahren werden. Dabei steht der Abstreifer bevorzugterweise sowohl mit der Innenseite des Gehäuses als auch mit der Außenseite des Hohlzylinders in Kontakt. Infolge dessen kommt es bei einer Verfahrbewegung des Abstreifers zur Entfernung von etwaigen Ablagerungen, die sich auf der Innenseite des Gehäuses und/oder auf der Außenseite des Hohlzylinders ausbilden können. Bei einer Verfahrbewegung des Abstreifers fährt dieser sowohl an der Innenseite des Gehäuses als auch an der Außenseite des Holzylinders entlang, infolge dessen es zu einem Mitbeziehungsweise Abreißen etwaiger hier befindlicher Ablagerungen kommt.The scraper is annular according to a further feature of the invention and arranged on the other hand within the annular gap space between the housing on the one hand and the hollow cylinder. Within this annular gap, the scraper can be moved in the height direction of the housing.
