Description

GESCHIRRSPULMASCHINE MIT EINEM WARMEROHR DISHWASHER WITH A WARM EAT
Die Erfindung betrifft eine Geschirrspülmaschine mit einem Spülbehälter.The invention relates to a dishwasher with a washing container.
Eine Geschirrspülmaschine weist bekanntlich ein Spülverfahren auf, dessen Programmablauf aus wenigstens einem Teilprogrammschritt "Vorspülen", einem Teilprogrammschritt "Reinigen", wenigstens einem Teilprogrammschritt "Zwischenspülen", einem Teilprogrammschritt "Klarspülen" und einem Teilprogrammschritt "Trocknen" besteht. Zur Erhöhung des Reinigungseffekts wird dabei die Spülflüssigkeit vor oder während eines Teilprogrammschrittes erwärmt. Dje Erwärmung der Spülflüssigkeit erfolgt üblicherweise mittels elektrischer Heizungen. Zur Trocknung von Spülgut in einer Geschirrspülmaschine sind unterschiedliche Trocknungssysteme bekannt.A dishwasher has, as is known, a rinsing process whose program sequence consists of at least one partial program step "pre-rinsing", one sub-program step "cleaning", at least one sub-program step "intermediate rinsing", one sub-program step "rinsing" and one sub-program step "drying". To increase the cleaning effect while the rinsing liquid is heated before or during a Teilprogrammschrittes. The heating of the rinsing liquid is usually carried out by means of electric heaters. For drying items to be washed in a dishwasher different drying systems are known.
Beispielsweise kann das Spülgut durch Eigenwärmetrocknung getrocknet werden, wenn die Spülflüssigkeit in einem Teilprogrammschritt „Klarspülen" erhitzt wird und somit das heiß klargespülte Spülgut durch die so aufgebaute Eigenwärme des Spülguts während des Trocknungsvorgangs von selbst trocknet. Um diese Eigenwärmetrocknung zu erreichen, wird die Spülflüssigkeit in dem Teilprogrammschritt „Klarspülen" auf eine bestimmte Temperatur erwärmt und über Sprüheinrichtungen auf das Spülgut aufgebracht. Durch die relativ hohe Temperatur der Spülflüssigkeit in dem Teilprogrammschritt „Klarspülen" von üblicherweise von 65°C bis 75°C wird erreicht, dass eine hinreichend große Wärmemenge auf das Spülgut übertragen wird, so dass das am Spülgut anhaftende Wasser durch die im Spülgut gespeicherte Wärme verdampft.For example, the items to be washed can be dried by self-heat drying if the rinsing liquid is heated in a "rinsing" part program step and the hot, rinsed items are automatically dried by the self-heat of the item to be washed during the drying process the partial program step "rinse" heated to a certain temperature and applied to the items to be washed via spraying. Due to the relatively high temperature of the rinsing liquid in the partial program step "rinsing" usually from 65 ° C to 75 ° C is achieved that a sufficiently large amount of heat is transferred to the items to be washed, so that the water adhering to the items by the heat stored in the items to be washed evaporated.
Bei einer weiteren bekannten Trocknungseinrichtung wird eine separate Heizquelle, z.B. ein Heißluftgebläse, im Spülbehälter dazu verwendet, das feuchte Luftgemisch beim Trocknungsvorgang zu erwärmen, damit die Luft im Spülbehälter eine größere Menge an Feuchtigkeit aufnehmen kann.In another known drying device, a separate heating source, e.g. a hot air blower, used in the rinsing tank to heat the humid air mixture during the drying process, so that the air in the washing container can absorb a larger amount of moisture.
Es sind Geschirrspülmaschinen bekannt, bei denen die Feuchtluft nach außen abgelassen wird. Dies ist nachteilig, da die umgebenden Küchenmöbel geschädigt werden. Daher sind weitere Geschirrspülmaschinen bekannt, bei denen die Feuchtluft vor dem Ausleiten über Kondensationsflächen geleitet wird, an denen die Feuchtigkeit kondensiert. Dieses Kondenswasser wird entweder in den Spülbehälter oder in spezielle Auffangbehälter geleitet.There are known dishwashers in which the moist air is discharged to the outside. This is disadvantageous because the surrounding kitchen furniture is damaged. Therefore, other dishwashers are known in which the moist air is passed before passing over condensation surfaces, where the moisture condenses. This condensation water is directed either into the rinsing container or into special collection containers.
Aus der DE 27 16 686 A1 ist eine Geschirrspülmaschine bekannt, bei dem ein Wärmerohr in den Spülbehälter ragt und dort eine Kühlfläche bildet. Die durch die heiße Feuchtluft abgegebene Wärme wird mittels des Wärmerohrs nach außen transportiert. Damit das Wärmerohr nicht auch Wärme während Teilprogrammschritten, bei denen eine Erwärmung in dem Spülbehälter gewünscht ist, ableitet, wird in diesen Teilprogrammschritten das Wärmerohr mit einem Inertgas gefüllt, das die Funktion des Wärmerohrs verhindert.From DE 27 16 686 A1 discloses a dishwasher is known in which a heat pipe protrudes into the washing and forms a cooling surface there. The heat released by the hot humid air is transported to the outside by means of the heat pipe. So that the heat pipe does not dissipate heat during partial program steps in which heating in the washing compartment is desired, the heat pipe is filled with an inert gas in these partial program steps, which prevents the function of the heat pipe.
Ein Nachteil bei den oben beschriebenen Heizungssysteme nach dem weiter oben beschriebenen Stand der Technik besteht darin, dass die Erwärmung der Spülflüssigkeit mit einem hohen Energiebedarf verbunden ist und die benötigte Wärmeenergie für jede Erwärmungsphase mittels der elektrischen Heizelemente neu erzeugt werden muss. Ebenso haben die bekannten Heizungssysteme den Nachteil, dass die Erwärmung der Spülflüssigkeit im Teilprogrammschritt "Klarspülen" sowie die Vorgänge im Teilprogrammschritt "Trocknen" selbst mit einem hohen Energiebedarf verbunden sind und die benötigte Wärmeenergie nach dem Trocknungsvorgang verloren geht.A disadvantage of the heating systems described above according to the prior art described above is that the heating of the rinsing liquid is associated with a high energy requirement and the required heat energy must be regenerated for each heating phase by means of the electrical heating elements. Likewise, the known heating systems have the disadvantage that the heating of the rinsing liquid in the partial program step "rinse" and the operations in the sub-program step "drying" are themselves associated with a high energy demand and the required heat energy is lost after the drying process.
Aufgabe der vorliegenden Erfindung ist es daher, eine Geschirrspülmaschine bereitzustellen, mit der es möglich ist, unter wirtschaftlichen Gesichtspunkten das im Spülbehälter befindliche Spülgut effizient zu reinigen und zu trocknen sowie den damit verbundenen Energieaufwand so gering wie möglich zu halten.It is therefore an object of the present invention to provide a dishwasher with which it is possible to efficiently clean and dry the items to be washed located in the washing container, and to keep the associated energy expenditure as low as possible from an economic point of view.
Diese Aufgabe wird durch die erfindungsgemäße Geschirrspülmaschine mit den Merkmalen 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 having the features according to claim 1. Advantageous developments of the present invention are characterized in the subclaims.
Die erfindungsgemäße Geschirrspülmaschine mit einem Spülbehälter weist mit dem Spülbehälter luftleitend verbundenes Leitungssystem auf, in das wenigstens ein Wärmerohr mit beiden Enden einragt, wobei das Wärmerohr einerseits zur Abkühlung und da- durch zur Trocknung als auch andererseits zur Erwärmung durchgeleiteter Luft aus dem Spülbehälter verwendet wird.The dishwashing machine according to the invention with a rinsing container has an air-conductively connected piping system to the rinsing container, into which at least one heat pipe protrudes with both ends, the heat pipe on the one hand being used for cooling and is used for drying as well as on the other hand for heating conducted air from the washing compartment.
Durch den Einsatz eines Wärmerohres ist nur noch eine gegenüber dem Stand der Technik wesentlich geringere Erwärmung des zu behandelnden Gutes notwendig, z.B. bei Geschirrspülmaschinen im Teilprogrammschritt „Klarspülen". Dies bedeutet eine wesentliche Energieeinsparung. Durch das Abkühlen der Luft wird deren Feuchtigkeitsaufnahmekapazität abgesenkt und der Feuchtigkeitsanteil der Luft fällt als Kondensat aus. Durch die Erwärmung der Luft wird deren Feuchtigkeitsaufnahmekapazität bei jedem Durchleiten durch das Leitungssystem wieder erhöht, was zur Verbesserung des Trocknungsergebnisses und/oder zur Verkürzung der Trocknungszeit führt. Bei dem geschlossenen Luft- system ist ein Austausch von verschmutzter Luft aus der Umgebung vollständig ausgeschlossen, womit eine Rückanschmutzung des behandelten Gutes verhindert wird. Mit der vorliegenden Erfindung ist eine Geschirrspülmaschine bereitgestellt, mit der es möglich ist, unter wirtschaftlichen Gesichtspunkten das im Spülbehälter befindliche Spülgut effizient zu reinigen und zu trocknen sowie den damit verbundenen Energieaufwand so gering wie möglich zu halten.The use of a heat pipe only requires a considerably lower heating of the material to be treated, compared to the state of the art, e.g. This means a significant energy saving By cooling the air, its moisture absorption capacity is lowered and the moisture content of the air precipitates as condensate The warming of the air increases its moisture absorption capacity each time it passes through the piping system, In the case of the closed air system, the exchange of polluted air from the environment is completely precluded, which prevents back soiling of the treated material. with which it is possible to efficiently clean and dry the items in the washing container located in the washing and to keep the associated energy consumption as low as possible.
Nach einem bevorzugten Merkmal der Erfindung wird Luft aus dem Spülbehälter in dem wenigstens einen Teilprogrammschritt "Trocknen" in das Leitungssystem und wieder zurück in den Spülbehälter geleitet, womit die oben erwähnten Vorteile in der erfindungsgemäßen Geschirrspülmaschine bestimmungsgemäß eingesetzt werden.According to a preferred feature of the invention, air is passed from the washing container in the at least one partial program step "drying" in the line system and back into the washing, whereby the above-mentioned advantages in the dishwasher according to the invention are used as intended.
In besonders vorteilhafter Weise weist der Spülbehälter einen Auslass mit einer Leitung zum einen Ende des Wärmerohrs, eine Leitung vom einen Ende des Wärmerohrs zum anderen Ende des Wärmerohrs und einen Einlass mit einer Leitung von dem anderen Ende des Wärmerohrs weist, wobei in der Leitung zum einen Ende des Wärmerohrs ein Gebläse angeordnet ist, das wenigstens einen Teil der Luft im Spülbehälter dem Leitungssystem wenigstens zeitweise zuführt. Bei dem geschlossenen Luftsystem ist ein Austausch von verschmutzter Luft aus der Umgebung vollständig ausgeschlossen, womit eine Rückanschmutzung des behandelten Gutes verhindert wird. Das Gebläse lässt sich leicht ansteuern, so dass der Einsatz des Wärmerohrs genau und einfacher gesteuert werden kann, z.B. gegenüber der in der DE 27 16686 A1 beschriebenen Geschirrspül- maschine. Außerdem verstärkt das Gebläse die Wirkung des Wärmerohrs, da die durchzuleitende Luft schneller gefördert wird.Most advantageously, the purge bin has an outlet with a conduit to one end of the heat pipe, a conduit from one end of the heat pipe to the other end of the heat pipe and an inlet with a conduit from the other end of the heat pipe, with one in the conduit End of the heat pipe, a fan is arranged, which supplies at least a portion of the air in the washing container at least temporarily the conduit system. In the closed air system, a replacement of polluted air from the environment is completely excluded, thus preventing back soiling of the treated material. The fan can be easily controlled, so that the use of the heat pipe can be controlled accurately and easily, for example compared to the dishwashing described in DE 27 16686 A1. machine. In addition, the fan increases the effect of the heat pipe, since the air to be conveyed is promoted faster.
Nach einem weiteren bevorzugten Merkmal der Erfindung wird die Luft mittels des Wärmerohrs abgekühlt. Damit wird die eigentliche Funktion eines Wärmerohrs, die Abkühlung unter Abtransport der aufgenommenen Wärmeenergie eingesetzt. Durch das Abkühlen der Luft wird deren Feuchtigkeitsaufnahmekapazität abgesenkt und der Feuchtigkeitsanteil der Luft fällt als Kondensat aus.According to another preferred feature of the invention, the air is cooled by means of the heat pipe. Thus, the actual function of a heat pipe, the cooling is used with removal of the absorbed heat energy. By cooling the air, its moisture absorption capacity is lowered and the moisture content of the air precipitates as condensate.
Nach einem weiteren bevorzugten Merkmal der Erfindung wird die Luft mittels des Wärmerohrs erwärmt. Damit wird die weitere Funktion des ohnehin vorhandenen Wärmerohrs - die transportierte Wärme aufgenommen beim Kühlen der Feuchtluft und beim Kondensieren der Feuchtigkeit aus der Feuchtluft - zur weiteren Energieeinsparung verwendet.According to another preferred feature of the invention, the air is heated by means of the heat pipe. Thus, the further function of the already existing heat pipe - the transported heat absorbed when cooling the moist air and condensing the moisture from the moist air - used to further save energy.
Nach einer vorteilhaften Ausführungsform der Erfindung ist in der Leitung zwischen Einlass und dem anderen Ende des Wärmerohrs eine Heizung angeordnet. Sollte die Erwärmung der Luft durch das Wärmerohr nicht ausreichen, wird zur Sicherstellung der Trocknungsfunktion die Luft zusätzlich mit einer Heizung erwärmt. Trotz des zusätzlichen Energieverbrauchs für die Heizung wird gegenüber dem vorbeschriebenen Stand der Technik eine Energieeinsparung erreicht.According to an advantageous embodiment of the invention, a heater is arranged in the line between the inlet and the other end of the heat pipe. If the heating of the air through the heat pipe is not sufficient, the air is additionally heated with a heater to ensure the drying function. Despite the additional energy consumption for the heating energy savings compared to the above-described prior art is achieved.
Nach einer weiteren vorteilhaften Ausführungsform der Erfindung ist in der Leitung zwischen dem Auslass und dem einen Ende des Wärmerohrs oder alternativ in der Leitung zwischen dem einen Ende des Wärmerohrs und dem anderen Ende des Wärmerohrs ein Kondensor angeordnet. Sollte der Feuchtigkeitsentzug der Luft durch das Wärmerohr nicht ausreichen, wird zur Sicherstellung der Trocknungsfunktion die Luft zusätzlich an einem Kondensor vorbeigeleitet, der den fehlenden Feuchtigkeitsentzug vornimmt.According to a further advantageous embodiment of the invention, a condenser is arranged in the conduit between the outlet and the one end of the heat pipe or alternatively in the conduit between the one end of the heat pipe and the other end of the heat pipe. If the dehumidification of the air through the heat pipe is not sufficient, the air is additionally passed to a condenser to ensure the drying function, which performs the missing dehumidification.
