Description

Geschirrspülmaschine mit einer Trocknungseinrichtung zum Trocknen von Spülgut Dishwasher with a drying device for drying dishes
Gegenstand der Erfindung ist eine Geschirrspülmaschine mit einer Trocknungseinrichtung zum Trocknen von Spülgut.The invention relates to a dishwasher with a drying device for drying dishes.
Bei der Trocknung von Spülgut in einer Geschirrspülmaschine nach der Klarspülphase sind unterschiedliche Trocknungssysteme bekannt. Beispielsweise kann mittels Eigenwärmetrocknung mit Wärmetauscher das Spülgut dadurch getrocknet werden, dass die Spülflüssigkeit zum Klarspülen auf eine Temperatur zwischen 65°C und 70°C erwärmt wird und somit das heiß klargespülte Spülgut durch die so aufgebaute Eigenwärme des Spülguts trocknet. Hierzu wird im Wärmetauscher die Klarspülflüssigkeit auf eine bestimmte Temperatur erwärmt und über die in der Geschirrspülmaschine vorhandenen Sprüheinrichtungen auf das Spülgut aufgebracht. Durch die relativ hohe Temperatur von üblicherweise 65° bis 70° wird erreicht, dass eine hinreichend große Wärmemenge auf das Spülgut übertragen wird, so dass das am Spülgut anhaftende Wasser durch diese im Spülgut vorliegende Wärme verdampft. Während dieser Eigenwärmetrocknung geht der Wärmeinhalt der Klarspülflotte im wesentlichen ungenutzt verloren, da dieser Wärmeinhalt lediglich zur Erwärmung des Spülguts dient. Durch diesen relativ hohen Energieeinsatz stellt sich weiterhin der Nachteil ein, dass sich neben dem Spülgut auch der Spülbehälter und die Dämmung des Spülbehälters, sowohl Wärme- als auch Geräuschdämmung, entsprechend erwärmt und somit die für die Trocknung notwendige Kondensationsleistung reduziert wird.Different drying systems are known for drying dishes in a dishwasher after the final rinse phase. For example, the items to be washed can be dried by means of self-heating drying with a heat exchanger by heating the rinsing liquid for rinsing to a temperature between 65 ° C. and 70 ° C. and thus drying the hot, rinsed items by the inherent heat of the items to be washed. For this purpose, the rinse aid liquid is heated to a certain temperature in the heat exchanger and applied to the items to be washed using the spray devices in the dishwasher. The relatively high temperature of usually 65 ° to 70 ° ensures that a sufficiently large amount of heat is transferred to the items to be washed, so that the water adhering to the items to be washed evaporates due to the heat present in the items to be washed. During this self-heating drying process, the heat content of the rinse aid liquor is essentially lost, since this heat content is only used to heat the dishes. This relatively high use of energy has the further disadvantage that, in addition to the items to be washed, the rinsing container and the insulation of the rinsing container, both heat and noise insulation, are heated accordingly and the condensation capacity required for drying is thus reduced.
Um das im Spülbehälter befindliche feuchte Luftgemisch möglichst rasch aus dem Spülbehälter zu leiten und somit die Trocknungsphase zu beschleunigen, ist es im Stand der Technik ferner bekannt, das feuchte Luftgemisch mittels geeigneter Gebläse aus dem Spülbehälter in die Außenatmosphäre zu befördern. Als Nachteil dieser Trocknungseinrichtungen hat sich erwiesen, dass das feuchte Luftgemisch zu Zerstörungen den angrenzenden Möbeln und sogar zu Schimmelbefall in den Räumen führen kann bzw. das heiße austretende Luftgemisch insbesondere für Kinder gefährlich ist oder auch lediglich von dem Benutzer als störend empfunden wird. Bei einer weiteren Trocknungseinrichtung des Standes der Technik wird Außenluft in den Spülbehälter geleitet und die Trocknungsleistung somit verbessert. Als nachteilig hat sich bei dieser Trocknungseinrichtung erwiesen, dass sich das Einleiten von Außenluft aus hygienischer Sicht, wegen der Rückanschmutzung des gereinigten Spülguts mit Bestand- teilen der Außenluft, wie z.B. Bakterien etc., nicht eignet.In order to conduct the moist air mixture in the washing container as quickly as possible from the washing container and thus to accelerate the drying phase, it is also known in the prior art to convey the moist air mixture from the washing container into the outside atmosphere by means of suitable fans. It has proven to be a disadvantage of these drying devices that the moist air mixture can destroy the adjacent furniture and even mold growth in the rooms, or the hot air mixture which escapes is particularly dangerous for children or is even perceived as annoying by the user. In a further drying device of the prior art, outside air is fed into the rinsing container and the drying performance is thus improved. It has proven to be a disadvantage of this drying device that the introduction of outside air is not suitable from a hygienic point of view, because of the back soiling of the cleaned dishes with components of the outside air, such as bacteria, etc.
Bei einer weiteren bekannten Trocknungseinrichtung wird eine Heizquelle im Spülbehälter dazu verwendet, das feuchte Luftgemisch zu erwärmen, so dass eine größere Menge an Feuchtigkeit von diesem Luftgemisch aufgenommen werden kann. Eine Heizquelle im Spülbehälter bildet wegen der Berührungsmöglichkeit eine Gefahrenquelle, Gefahr von Verletzungen und Verbrennungen und kann zu Beschädigungen von in deren Nähe eingelagertem Spülgut aus temperaturempfindlichen Materialien , wie z.B. Kunststoff etc., führen.In another known drying device, a heat source in the rinsing container is used to heat the moist air mixture, so that a larger amount of moisture can be absorbed by this air mixture. A heat source in the rinsing container is a source of danger due to the possibility of contact, risk of injury and burns and can damage items in the vicinity made of temperature-sensitive materials, e.g. Plastic, etc.
Aufgabe der vorliegenden Erfindung ist es daher, eine Trocknungseinrichtung bereitzustellen, mit der es möglich ist, unter wirtschaftlichen und hygienischen Gesichtspunkten, das im Spülbehälter befindliche feuchte Spülgut rasch zu trocknen.It is therefore an object of the present invention to provide a drying device with which it is possible, from an economical and hygienic point of view, to quickly dry the moist items to be washed in the washing compartment.
Diese Aufgabe wird durch die erfindungsgemäße Geschirrspülmaschine mit den Merkma- len gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the dishwasher according to the invention with the features according to claim 1. Advantageous developments of the present invention are characterized in the subclaims.
Bei der erfindungsgemäßen Geschirrspülmaschine mit einer Trocknungseinrichtung zum Trocknen von Spülgut ist erfindungsgemäß die Trocknungseinrichtung innerhalb der Ge- schirrspülmaschine angeordnet und wälzt ausschließlich das in einem Spülbehälter der Geschirrspülmaschine befindliche Luftgemisch um, bestehend aus einem Gebläse zum Ansaugen von im wesentlichen feuchten Luftgemisch, einer an das Gebläse angeschlossenen, gegenüber dem Spülbehälter abgeschlossenen Transportstrecke, durch die das im wesentliche feuchte Luftgemisch transportiert wird und einer Heizeinrichtung, die in der Transportstrecke angeordnet und so ausgebildet ist, dass das daran vorbeistreichende feuchte Luftgemisch erwärmt wird, sowie einem Auslassbereich durch den die erwärmte Luft in dem Spülbehälter zurückgeleitet wird. Vorteilhafterweise ist die Transportstrecke in einer Seitenwand oder der Tür der Geschirrspülmaschine angeordnet. Ebenso ist es möglich, die Transportstrecke im rückseitigen Bereich des Spülbehälters anzuordnen, jedoch bietet sich insbesondere die Seitenwand und die Türe an, weil in diesen Bereichen bereits Ausbrüche vorhanden sind, wie beispielsweise ein Expansionsschacht zum Abfangen von Druckspitzen im Spülbehälter.In the dishwasher according to the invention with a drying device for drying items to be washed, the drying device according to the invention is arranged inside the dishwasher and only circulates the air mixture located in a washing container of the dishwasher, consisting of a fan for sucking in an essentially moist air mixture, one to the fan Connected, sealed off from the rinsing container, through which the essentially moist air mixture is transported and a heating device, which is arranged in the transport line and is designed so that the passing damp air mixture is heated, and an outlet area through which the heated air in the Rinsing container is returned. The transport path is advantageously arranged in a side wall or the door of the dishwasher. It is also possible to arrange the transport route in the rear area of the rinsing container, but the side wall and the door are particularly useful because there are already cutouts in these areas, such as an expansion shaft to absorb pressure peaks in the washing container.
Bevorzugt wird das feuchte Luftgemisch im oberen Bereich des Spülbehälters angesaugt und im unteren Bereich des Spülbehälters wieder in diesen eingeblasen.The moist air mixture is preferably sucked in in the upper region of the rinsing container and blown back into the lower region of the rinsing container.
Nach einer vorteilhaften Ausführungsform der vorliegenden Erfindung ist das Gebläse in der oberen Hälfte bevorzugt im oberen Viertel und die Heizeinrichtung in der unteren Hälfte bevorzugt im unteren Viertel des Spülbehälters angeordnet.According to an advantageous embodiment of the present invention, the fan in the upper half is preferably arranged in the upper quarter and the heating device in the lower half is preferably arranged in the lower quarter of the washing compartment.
Bei einer weiteren Ausführungsform der vorliegenden Erfindung ist das Gebläse in der oberen Hälfte des Spülbehälters und die Heizeinrichtung über einen wesentlichen Teilbe- reich der Transportstrecke angeordnet.In a further embodiment of the present invention, the blower is arranged in the upper half of the washing compartment and the heating device is arranged over a substantial part of the transport route.
Zweckmäßigerweise ist sowohl das Gebläse als auch die Heizeinrichtung mit der Programmsteuerung der Geschirrspülmaschine so verbunden, dass entsprechend des Spülprogrammstatus das Gebläse und entsprechend die Heizeinrichtung angesteuert wird.Both the blower and the heating device are expediently connected to the program control of the dishwasher in such a way that the blower and the heating device are activated in accordance with the washing program status.
Mit der erfindungsgemäßen Geschirrspülmaschine wird der Vorteil erreicht, dass keine feuchtigkeitsbeladene Luft an die Umgebungsatmosphäre abgegeben wird, so dass schädliche Einflüsse auf das Mobiliar, wie beispielsweise Schimmelbildung vermieden wird. Ferner kommt das Spülgut beim Trocknen nicht mit Außenluft in Kontakt, so dass ein hoher hygienischer Standart gewährleistet werden kann. Ein weiterer vorteilhafter Effekt der erfindungsgemäßen Geschirrspülmaschine ist es, dass die Klarspültemperatur gegenüber dem Stand der Technik wesentlich gesenkt werden kann und so etwa bei 50°C liegt, bzw. so gewählt werden kann, dass gerade keine Schaumbildung durch den Klar- spüler in der Klarspülflüssigkeit entsteht. Durch diese Absenkung der Klarspültemperatur wird erfahrungsgemäß eine derartige Energiemenge eingespart, dass sie auch nicht durch den Energieaufwand für das Gebläse und die Luftheizung verbraucht wird. Weitere Vorteile der erfindungsgemäßen Geschirrspülmaschine sind der Wegfall von Heizquellen im Spülbehälter, die bekanntermaßen als Verletzungsquelle dienen können, sowie ferner eine optische Aufwertung des Spülbehälters. Neben den Vorteilen der Energieeinsparung sind weiterhin durch die Temperaturabsenkung der Klarspülflüssigkeit die Belastungseinflüsse auf das Spülgut geringer, so dass beispielsweise in Keramiken oder irdenen Gefäßen die Gefahr von Haarrissen gesenkt wird.The dishwasher according to the invention achieves the advantage that no moisture-laden air is released into the ambient atmosphere, so that harmful influences on the furniture, such as mold growth, are avoided. Furthermore, the items to be washed do not come into contact with outside air during drying, so that a high hygienic standard can be guaranteed. A further advantageous effect of the dishwasher according to the invention is that the rinse aid temperature can be significantly reduced compared to the prior art and is approximately 50 ° C., or can be selected such that there is no foam formation by the rinse aid in the rinse aid liquid arises. Experience has shown that this reduction in rinse temperature saves such an amount of energy that it is not consumed by the energy required for the blower and air heating. Further advantages of the dishwasher according to the invention are the elimination of heating sources in the washing compartment, which are known to serve as a source of injury, and also an optical upgrading of the washing compartment. In addition to the advantages of energy saving, the lowering of the temperature of the rinse aid also reduces the stress on the items to be washed, so that the risk of hairline cracks is reduced, for example, in ceramics or earthenware vessels.
Ferner bietet die erfindungsgemäße Geschirrspülmaschine eine homogene Wärmeverteilung innerhalb der Trocknungsluft, so dass eine höhere Effizienz und damit bessere Energiewerte für den Betrieb der erfindungsgemäßen Geschirrspülmaschine festgestellt wer- den können.Furthermore, the dishwasher according to the invention offers a homogeneous heat distribution within the drying air, so that a higher efficiency and thus better energy values for the operation of the dishwasher according to the invention can be determined.

Während der Trocknungsphase wird das mit einer Programmsteuereinheit (nicht dargestellt) verbundene Gebläse 2 aktiviert und saugt das feuchte Luftgemisch aus dem Spülbehälter an. Bei dem weiteren Transport des feuchten Luftgemischs durch die Transportstrecke 3 wird das feuchte Luftgemisch an der ebenfalls mit der Programmsteuereinheit (nicht dargestellt) verbundenen Heizeinrichtung 4 erwärmt und ist somit in der Lage, eine größere Menge an Feuchtigkeit aufzunehmen. Durch den am Ende der Transportstrecke 3 befindliche Auslassbereich 7 kann das nunmehr erwärmte feuchte Luftge- misch in den Spülbehälter 1 austreten und sich dort zum Trocknen des feuchten Spülguts verteilen. Durch die so aufgebaute Umwälzströmung wird ein rasches und homogenes Trocknungsverhalten innerhalb des Spülbehälters erzielt.The dishwasher according to the invention, not explained in greater detail, according to FIG. 1 has a washing container 1 and a drying device in a door 6. The drying device consisting of a blower 2, a transport path 3 and a heating device 4. During the drying phase, the blower 2 connected to a program control unit (not shown) is activated and sucks in the moist air mixture from the washing container. When the moist air mixture is transported further through the transport path 3, the moist air mixture is heated at the heating device 4, which is also connected to the program control unit (not shown), and is thus able to absorb a larger amount of moisture. Through the outlet area 7 located at the end of the transport path 3, the now heated humid air Mix out in the washing container 1 and distribute there to dry the damp wash ware. The circulating flow thus constructed ensures rapid and homogeneous drying behavior within the rinsing tank.
Bei der erfindungsgemäßen nicht näher erläuterten Geschirrspülmaschine gemäß Figur 2 ist in der an einer Seitenwand eines Spülbehälters 1 angeordneten Transportstrecke 3 eine Heizeinrichtung 4 über einen wesentlichen Teilbereich der Transportstrecke 3 angeordnet. Diese könnte auch so angeordnet sein, dass ein wesentlicher Teilbereich der Transportstrecke 3 damit ausgekleidet ist. Das vorbeiströmende feuchte Luftgemisch wird bereits unmittelbar nach Passieren des Gebläses 2 erwärmt. Das erwärmte feuchte Luft- gemisch 5 tritt am Ende der Transportstrecke 3 im unteren Viertel des Spülbehälters 1 aus und erzeugt eine Umwälzströmung zum Trocknen des Spülguts.In the dishwashing machine according to the invention, which is not explained in greater detail, according to FIG. This could also be arranged in such a way that a substantial part of the transport route 3 is lined with it. The moist air mixture flowing past is heated immediately after passing through the blower 2. The heated, moist air mixture 5 emerges at the end of the transport path 3 in the lower quarter of the washing container 1 and generates a circulating flow for drying the items to be washed.
Mit der erfindungsgemäßen Geschirrspülmaschine wird der Vorteil erreicht, dass keine feuchtigkeitsbeladene Luft an die Umgebungsatmosphäre abgegeben wird, so dass schädliche Einflüsse auf das Mobiliar, wie beispielsweise Schimmelbildung vermieden wird. Femer kommt das Spülgut beim Trocknen nicht mit Außenluft in Kontakt, so dass ein hoher hygienischer Standart gewährleistet werden kann. Ein weiterer vorteilhafter Effekt der erfindungsgemäßen Geschirrspülmaschine 1 ist es, dass die Klarspültemperatur gegenüber dem Stand der Technik wesentlich gesenkt werden kann und so etwa bei 50°C liegt, bzw. so gewählt werden kann, dass gerade keine Schaumbildung durch den Klar- spüler in der Klarspülflüssigkeit entsteht. Durch diese Absenkung der Klarspültemperatur wird erfahrungsgemäß eine derartige Energiemenge eingespart, dass sie auch nicht durch den Energieaufwand für das Gebläse 2 und die Luftheizung 4 verbraucht wird. The dishwasher according to the invention achieves the advantage that no moisture-laden air is released into the ambient atmosphere, so that harmful influences on the furniture, such as mold growth, are avoided. Furthermore, the items to be washed do not come into contact with outside air during drying, so that a high hygienic standard can be guaranteed. A further advantageous effect of the dishwasher 1 according to the invention is that the rinse aid temperature can be significantly reduced compared to the prior art and is approximately 50 ° C., or can be selected such that no foam is formed by the rinse aid in the dishwasher Rinse aid is produced. Experience has shown that this reduction in rinse temperature saves such an amount of energy that it is not consumed by the energy required for the blower 2 and the air heater 4.
