Description

Die Erfindung betrifft eine gasbeheizte Geschirrspülmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a gas-heated dishwasher according to the preamble of patent claim 1.

Aus der DE 544 010 ist eine Geschirrwaschvorrichtung mit Wasch- und Spülflüssigkeitsbehälter und stillstehendem Geschirrkorb bekannt, bei der über einen untergestellten Gasbrenner die Spülflüssigkeit auf eine hohe Temperatur während des Waschvorgangs erwärmt wird, wobei die Trocknung des Spülguts mittelbar über die Erwärmung der Spülflüssigkeit geschieht. Hierzu weist die Geschirrwaschvorrichtung einen Waschflüssigkeitsbehälter und einen Spülflüssigkeitsbehälter auf, wobei der Waschflüssigkeitsbehälter mittelbar über den Spülflüssigkeitsbehälter erwärmt wird. Durch Erhitzen des Spülflüssigkeitsbehälters steigt warme Luft nach oben und trägt so zur Trocknung des Spülguts bei. Als nachteilig hat sich bei dieser Geschirrwaschvorrichtung erwiesen, dass eine relativ große Flüssigkeitsmenge verbraucht wird, sowie lediglich über die Luft Wärme transportiert werden soll, um das benetzte Spülgut zu trocknen.From DE 544 010 a dishwashing apparatus with washing and rinsing liquid container and stationary dish rack is known, in which the rinsing liquid is heated to a high temperature during the washing process via a submerged gas burner, wherein the drying of the dishes occurs indirectly via the heating of the rinsing liquid. For this purpose, the dishwashing apparatus has a washing liquid container and a rinsing liquid container, wherein the washing liquid container is indirectly heated via the rinsing liquid container. By heating the rinsing fluid container warm air rises and thus contributes to the drying of the dishes. A disadvantage has been found in this dishwashing apparatus that a relatively large amount of liquid is consumed, and only about the air heat to be transported to dry the wetted items to be washed.

Aus der US-A-3104669 ist eine gasbeheizte Geschirrspülmaschine bekannt, wobei der Gasbrenner im Motorraum angeordnet ist und die in einer Rohrschleife befindliche Luft erhitzt. Da der Gasbrenner innerhalb des Rohrsystems angeordnet ist, erhitzt er die darin befindliche Luft, die ihrerseits die Rohroberfläche erwärmt, um damit den Trocknungsvorgang im Spülbehälter zu beschleunigen. Hierzu führt die im wesentlichen waagrecht angeordnete Rohrschleife im Motorraum, in der der Gasbrenner angeordnet ist, zur Rückwand der Geschirrspülmaschine und mündet dort in einen nach oben offenen Schacht, der im wesentlichen diagonal an der Rückwand der Geschirrspülmaschine verläuft, um so eine möglichst große Oberfläche zum Spülbehälter hin zu entfalten. Aufgrund des in der Rohrschleife angeordneten Gasbrenners sind die durch das Abbrennen des Gases entstandenen Abgase durch die Rohrschleife nach außen abzuführen. Dies geschieht über den im wesentlichen diagonal an der Rückwand verlaufenden Luftschacht, der an seinem oberen Ende. d.h. der Arbeitsplatte der Geschirrspülmaschine, offen ist. Die Verwendung eines Abgasrohres, welches im Rückbereich einer Arbeitsplatte angeordnet ist, kann bereits aus Offensichtlichkeitsgründen hinsichtlich der Praktikabilität und Sicherheit als nachteilig erachtet werden. Ebenso ist die Effizienz eines Gasbrenners, der lediglich ein mit Luft gefülltes Rohrsystem erwärmt, um damit die Trocknungszeit von Spülgut zu verringern, sehr gering.From US-A-3104669 a gas-heated dishwasher is known, wherein the gas burner is arranged in the engine compartment and heats the air located in a pipe loop. Since the gas burner is located inside the pipe system, it heats the air inside it, which in turn heats the pipe surface to speed up the drying process in the washing tank. For this purpose, the substantially horizontally arranged pipe loop in the engine compartment, in which the gas burner is arranged, leads to the rear wall of the dishwasher and flows there into an open-topped shaft, which runs essentially diagonally on the rear wall of the dishwasher, in order to maximize the surface area for the dishwasher Unfolding rinsing container. Due to the arranged in the pipe loop gas burner, the exhaust gases resulting from the burning of the gas to be discharged through the pipe loop to the outside. This is done via the substantially diagonally extending on the rear wall duct, at its upper end. ie the worktop of the dishwasher, is open. The use of an exhaust pipe, which is arranged in the rear region of a worktop, can already off Obviousness in terms of practicability and safety. Likewise, the efficiency of a gas burner, which heats only a tube system filled with air in order to reduce the drying time of items to be washed, is very low.

Aufgabe der vorliegenden Erfindung ist es daher, eine gasbeheizte Geschirrspülmaschine bereitzustellen, die sowohl für das Trocknen des Spülguts und das Erwärmen der Spülflüssigkeit in effizienter Weise geeignet ist, wobei die Möglichkeit gegeben sein sollte, oberhalb der Geschirrspülmaschine eine Arbeitsplatte vorzusehen.The object of the present invention is therefore to provide a gas-heated dishwasher which is suitable both for drying the dishes and heating the dishwashing liquid in an efficient manner, whereby it should be possible to provide a worktop above the dishwashing machine.

Diese Aufgabe wird durch die erfindungsgemäße Geschirrspülmaschine mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the dishwasher according to the invention having the features of claim 1. Advantageous embodiments of the invention are characterized in the subclaims.

Bei der erfindungsgemäßen Geschirrspülmaschine wird ein Gasbrenner angeordnet, der zum Erwärmen der Spülflüssigkeit und Trocknen des Spülguts dient, wobei der Gasbrenner so ausgebildet und im Motorraum angeordnet ist, dass er zumindest einen mit einem Fluid gefüllten, geschlossenen Rohrheizkörper während eines Teilprogrammabschnitts "Trocknen" und die Spülflüssigkeit während der Teilprogrammabschnitte mit Spülflüssigkeitseinsatz erwärmt.In the dishwasher according to the invention, a gas burner is arranged, which serves for heating the rinsing liquid and drying the dishes, wherein the gas burner is designed and arranged in the engine compartment, that it at least one filled with a fluid, closed tubular heater during a partial program section "drying" and the Rinsing fluid during the subprogram sections heated with rinsing liquid.

Vorzugsweise wird der mit einem Fluid gefüllte, beispielsweise einer Flüssigkeit oder einem Gas, geschlossene Rohrheizkörper bei Verwendung einer Flüssigkeit als Fluid mit einem Frostschutzmittel gegen Frost geschützt.Preferably, the filled with a fluid, such as a liquid or a gas, closed tubular heater is protected when using a liquid as a fluid with an antifreeze against frost.

Bei Erwärmung des Fluids wird dieses aufgrund der sich ausbildenden Temperaturunterschiede innerhalb des geschlossenen Rohrheizkörpers in diesem transportiert, es kann jedoch auch vorteilhaft sein, für den Transport des Fluids eine eigene Pumpe hierzu in den geschlossenen Rohrheizkörper zu integrieren, der die Zirkulation des Fluids unterstützt.When the fluid is heated, this is due to the developing temperature differences within the closed tubular heater transported in this, but it may also be advantageous for the transport of the fluid to integrate its own pump in the closed tubular heater, which supports the circulation of the fluid.

Vorteilhafterweise wird der geschlossene, mit einem Fluid gefüllte Rohrheizkörper lediglich während des Teilprogrammabschnitts "Trocknen" erwärmt, es kann jedoch auch vorteilhaft sein, den geschlossenen, mit einem Fluid gefüllten Rohrheizkörper während des gesamten Spülprogramms zu erwärmen.Advantageously, the closed, filled with a fluid pipe heater is heated only during the part program section "drying", but it may also be advantageous be to heat the closed, filled with a fluid tubular heater during the entire wash program.

Um eine möglichst effiziente Trocknung während des Teilprogrammabschnitts "Trocknen" zu erreichen, ist es zweckmäßig, den geschlossenen, mit einem Fluid gefüllten Rohrheizkörper so auszubilden, dass eine möglichst große Fläche des Rohrheizkörpers zu einer Wand des Spülbehälters benachbart ist. Vorteilhafterweise ist der geschlossene, mit einem Fluid gefüllte Rohrheizkörper mäanderförmig ausgebildet und in einer Seitenwand oder der Rückwand der Geschirrspülmaschine angeordnet. Zweckmäßigerweise erstreckt sich der geschlossene, mit Fluid gefüllte Rohrheizkörper von der Seiten- oder Rückwand zumindest abschnittsweise bis in den Motorraum der Geschirrspülmaschine, in dem der Gasbrenner angeordnet ist. Zur Verbesserung der Trocknungswirkung weist damit der geschlossene, mit Fluid gefüllte Rohrheizkörper eine möglichst große Oberfläche auf, um so die darin gespeicherte Energie möglichst rasch an die Atmosphäre im Spülbehälter abgeben zu können. Diese Energie dient zur Erwärmung der Atmosphäre im Spülbehälter, um die an dem Spülgut anhaftende Feuchtigkeit aufnehmen zu können.In order to achieve the most efficient drying possible during the program section "drying", it is expedient to form the closed, filled with a fluid tubular heater so that the largest possible area of the tubular heater is adjacent to a wall of the washing. Advantageously, the closed, filled with a fluid tubular heater is formed meander-shaped and arranged in a side wall or the rear wall of the dishwasher. Conveniently, the closed tubular heater filled with fluid extends from the side or rear wall, at least in sections, into the engine compartment of the dishwasher in which the gas burner is arranged. To improve the drying effect thus has the closed, filled with fluid tubular heater on the largest possible surface, so as to be able to deliver the stored energy as quickly as possible to the atmosphere in the washing can. This energy is used to heat the atmosphere in the washing container in order to absorb the adhering to the dishes moisture.

Bei einer bevorzugten Ausführungsform der vorliegenden Erfindung werden Abschnitte des geschlossenen, mit Fluid gefüllten Rohrheizkörpers und Zufuhrleitungen für die Spülflüssigkeit in einem Wärmetauscher zusammengeführt, der mit dem Gasbrenner erwärmt wird.In a preferred embodiment of the present invention, portions of the closed fluid-filled tubular heater and irrigation fluid supply lines are combined in a heat exchanger which is heated by the gas burner.

Bei einer bevorzugten Ausführungsform der vorliegenden Erfindung ist ein elektrischer Energielieferant, vorzugsweise ein Akkumulator, im Bodenbereich der Geschirrspülmaschine vorgesehen, der zumindest so viel elektrische Energie liefern kann, um die notwendige Leistung für den Ablauf des Spülprogramms, die Aussteuerung und Betätigung der Pumpen etc. für einen Spülprogrammablauf aufzubringen.In a preferred embodiment of the present invention, an electrical energy supplier, preferably an accumulator, is provided in the bottom area of the dishwasher, which can supply at least as much electrical energy to provide the necessary power for the lavage program, the control and actuation of the pumps, etc. to apply a rinse program.

Vorteilhafterweise wird der Akkumulator ständig aufgeladen, sofern er an ein elektrisches Netz angeschlossen ist und dieses ein Aufladen erlaubt.Advantageously, the accumulator is constantly charged, if it is connected to an electrical network and this allows charging.

Bei einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung ist die Geschirrspülmaschine so ausgebildet, dass ein Spülprogramm erst dann zu starten bereit ist, wenn ein Signal des Akkumulators den Startbefehl des Benutzers freigibt, abhängig vom Ladezustand des Akkumulators. Grundsätzlich muss sichergestellt sein, dass das gesamte Spülprogramm mit der gespeicherten Energie abgeschlossen werden kann.In a particularly preferred embodiment of the present invention, the dishwasher is designed such that a wash program is only ready to start when a signal from the battery releases the start command of the user from the state of charge of the accumulator. Basically, it must be ensured that the entire washing program can be completed with the stored energy.

Die erfindungsgemäße Geschirrspülmaschine weist die Vorteile auf, dass durch die Verwendung von Gas die erforderliche elektrische Energie erheblich reduziert wird und so die Wirtschaftlichkeit zumindest in einigen Ländern oder Regionen erhöht wird. Weiterhin wird sich die erfindungsgemäße Geschirrspülmaschine in Ländern und Regionen als vorteilhaft erweisen, deren elektrisches Stromnetz nicht immer zuverlässig zur Verfügung steht oder lediglich zu bestimmten Tages- oder Nachtzeiten in Kontingenten verwendet werden kann.The dishwasher according to the invention has the advantages that the use of gas, the required electrical energy is significantly reduced and thus the efficiency is increased, at least in some countries or regions. Furthermore, the dishwashing machine according to the invention will prove to be advantageous in countries and regions whose electric power grid is not always reliably available or can only be used in quotas at certain times of day or night.

Je nach Teilprogrammabschnitt des Spülprogramms wird über ein elektrisches oder mechanisches Signal der Gasbrenner 2 gestartet, um in dem darüber befindlichen Wärmetauscher 5 ein in dem geschlossenen Rohrheizkörper 3 befindliches Fluid, beispielsweise eine Flüssigkeit oder ein Gas, zu erwärmen. Zweckmäßigerweise wird das Fluid über die Pumpe 9 in dem geschlossenen Rohrheizkörper 3 zirkulierend bewegt. In der Anordnung gemäß Figur 2 wird eine bevorzugte Ausführungsform der vorliegenden erfindungsgemäßen Geschirrspülmaschine 1 gezeigt, wobei die zum Transport der Spülflüssigkeit vorgesehene Zufuhrleitung 4 mittels Gasbrenner 2 erwärmt wird. Die erwärmte Spülflüssigkeit wird über eine Pumpe 9 in die jeweiligen Bereiche des Spülbehälters transportiert und durch die Sprüharme dort entsprechend des jeweiligen Teilprogrammabschnitts des Spülprogramms eingesetzt. Der Gasbrenner 2 weist vorteilhafterweise einen Bereich auf, der elektronisch oder mechanisch entsprechend der jeweiligen Programmstufe angesteuert werden kann und über einen Wärmetauscher 5 das Fluid in dem geschlossenen Rohrheizkörper 3 erhitzt. Aufgrund physikalischer Gesetzmäßigkeiten beginnt das erwärmte Fluid, in dem geschlossenen Rohrheizkörper 3 zu zirkulieren, so dass eine im wesentlichen ausgeglichene Wärmeverteilung innerhalb des Rohrheizkörpers 3 festgestellt werden kann. Zweckmäßigerweise wird der geschlossene, mit Fluid gefüllte Rohrheizkörper 3 unmittelbar an den Spülbehälter benachbart angeordnet, so dass die so aufgeheizte Spülbehälterwand die Atmosphäre im Spülbehälter erwärmt und so die Trocknung während des Teilprogrammabschnitts "Trocknen" günstig beeinflusst.In the arrangement according to Figure 1, a dishwasher 1 is shown, which has a meandering tubular heating element 3 in its left side wall, with a pump 9, which is technically connected via a gas burner 2 and a directly above arranged heat exchanger 5. Depending on the partial program section of the washing program, the gas burner 2 is started via an electrical or mechanical signal in order to heat a fluid, for example a liquid or a gas, contained in the closed tubular heating element 3 in the heat exchanger 5 located above it. Conveniently, the fluid is circulated through the pump 9 in the closed tubular heater 3. In the arrangement according to FIG. 2, a preferred embodiment of the present inventive dishwashing machine 1 is shown, wherein the supply line 4 provided for transporting the rinsing liquid is heated by means of a gas burner 2. The heated rinsing liquid is a pump 9 in the transported respective areas of the washing and used there by the spray arms according to the respective part program section of the wash program. The gas burner 2 advantageously has an area which can be controlled electronically or mechanically in accordance with the respective program stage and heats the fluid in the closed tubular heater 3 via a heat exchanger 5. Due to physical laws, the heated fluid begins to circulate in the closed tubular heater 3, so that a substantially balanced heat distribution within the tubular heater 3 can be determined. Conveniently, the closed tubular heating element 3 filled with fluid is arranged directly adjacent to the rinsing container, so that the rinsing container wall heated in this way heats the atmosphere in the rinsing container and thus beneficially influences the drying during the "drying" subprogram section.

Vorteilhafterweise ist in der erfindungsgemäßen Geschirrspülmaschine 1 ein elektrischer Energielieferant, im gezeigten Ausführungsbeispiel ein Akkumulator A, vorgesehen, der zumindest die erforderliche elektrische Energiemenge für den Start des Gasbrenners 2, die Steuerung des Spülprogramms und die Steuerung und Drehung der Pumpen liefert, die für den Ablauf zumindest eines Spülprogramms erforderlich ist. In besonders vorteilhafter Weise lädt sich der Akkumulator A ständig auf, sofern elektrisches Energie durch ein externes Netz zur Aufladung zur Verfügung steht.Advantageously, in the dishwasher 1 according to the invention, an electrical energy supplier, in the illustrated embodiment, an accumulator A, provided that at least the required amount of electrical energy for the start of the gas burner 2, the control of the wash program and the control and rotation of the pump provides for the process at least one washing program is required. In a particularly advantageous manner, the accumulator A constantly charged, provided that electrical energy is available for charging by an external network.

Bei einer nicht gezeigten Ausführungsform der vorliegenden Erfindung ist die Geschirrspülmaschine 1 so ausgebildet, dass ein Spülprogramm erst dann zu starten bereit ist, wenn ein Signal des Akkumulators A den Startbefehl des Benutzers freigibt, abhängig vom Ladezustand des Akkumulators A, wobei sichergestellt sein muss, dass das gesamte Spülprogramm mit der gespeicherten Energie abgeschlossen werden kann.In a non-illustrated embodiment of the present invention, the dishwasher 1 is designed so that a wash program is ready to start only when a signal of the accumulator A releases the start command of the user, depending on the state of charge of the accumulator A, where it must be ensured that the entire wash program can be completed with the stored energy.

Die erfindungsgemäße Geschirrspülmaschine 1 weist die Vorteile auf, dass durch die Verwendung von Gas die erforderliche elektrische Energie erheblich reduziert wird und so die Wirtschaftlichkeit zumindest in einigen Ländern oder Regionen erhöht wird. Weiterhin wird sich die erfindungsgemäße Geschirrspülmaschine 1 in Ländern und Regionen als vorteilhaft erweisen, deren elektrisches Stromnetz nicht immer zuverlässig zur Verfügung steht oder lediglich zu bestimmten Tages- oder Nachtzeiten in Kontingenten verwendet werden kann.The dishwashing machine 1 according to the invention has the advantages that the use of gas considerably reduces the required electrical energy and thus increases the economic efficiency, at least in some countries or regions.
