Description
Die Erfindung betrifft ein Verfahren zum Betrieb einer Haushalt-Geschirrspülmaschine, die mit aus den Teilprogrammen Reinigen, Zwischenspülen, Klarspülen und Trocknen wählbaren Programmen betätigbar ist, wobei in den Teilprogrammen Reinigen, Zwischenspülen und Klarspülen die im Sumpf des Spülbehälters vorhandenen Flüssigkeitsmengen mittels einer Umwälzpumpe Spritzeinrichtungen zugeführt und unter Beaufschlagung des Geschirrs umgewälzt werden, wobei in den Teilprogrammen Reinigen und Klarspülen die Flüssigkeitsmengen aufgeheizt und mit Zusatzmitteln versetzt werden. Die üblichen, auf dem Markt befindlichen Haushalt-Geschirrspülmaschinen können nach diesem Verfahren betrieben werden.The invention relates to a method for operating a household dishwasher, which can be operated with programs that can be selected from the sub-programs cleaning, intermediate rinsing, rinsing and drying, wherein in the sub-programs cleaning, intermediate rinsing and rinsing, the liquid quantities present in the sump of the washing container are supplied with spray devices by means of a circulation pump and are circulated while the dishes are loaded, the amounts of liquid being heated and admixed with additives in the sub-programs cleaning and rinsing. The usual household dishwashers on the market can be operated using this method.
Zum umweltfreundlichen Betrieb dieser Maschinen sind Vorschläge bekannt, die darauf abzielen, daß die Spülprogramme wasser- und energiesparender ablaufen.Proposals are known for the environmentally friendly operation of these machines, which aim to make the washing programs run more water and energy-saving.
Zur Verminderung der Heizenergie für das Erwärmen der Spülflotten ist ein Verfahren zum Spülen von Geschirr bekannt (DE-OS 32 45 145), bei dem nach einem letzten, mit aufgeheiztem Wasser durchgeführten Spülgang erwärmte Luft zum Trocknen über das Geschirr geleitet und der Wasserdampf aus dem Spülbehälter ausgeleitet wird, derart, daß dem Wasser im letzten Spülgang ein Klarspülmittel zugesetzt wird, daß das Wasser anschließend nur auf eine Temperatur von ca. 45°C aufgeheizt wird, bei der ein Aufschäumen des Klarspülmittels gerade sicher vermieden ist und daß danach die erwärmte Luft durch den Spülbehälter geführt wird. Nach dieser Verfahrensweise wird die für das Verteilen des Klarspülmittels notwendige Wassermenge, im Gegensatz zu den eingangs genannten, üblicherweise bei den auf dem Markt befindlichen Geschirrspülmaschinen angewandten Spülverfahren, nicht auf ca. 70°C, sondern nur auf eine Temperatur von ca. 45°C aufgeheizt. Nach dem Übersprühen der Geschirrteile mit dem auf 45°C erwärmten Klarspülmittel-Wasser folgt ein Abpumpvorgang, zu dessen Beginn bereits das Einführen einer erwärmten Luft erfolgen soll. Ohne daß die DE-OS 32 45 145 darüber Aufschluß gibt, wo das Aufheizen der beim Abpumpen des Klarspülmittel-Wassers in den Spülbehälter einzuführenden erwärmten Luft, welche dem Aufstellraum der Geschirrspülmaschine entnommen wird, erfolgt, ist hervorgehoben, daß bei dieser Verfahrensweise für das Aufheizen der Luft aus dem Aufstellraum bis zum Trockenblasen der Geschirrteile eine geringere Wärmemenge erforderlich ist, als sie für eine Aufheizung des Wassers im Klarspülgang auf eine Temperatur von bis zu 70° erforderlich ist, wenn ein statischer Trokkenvorgang des Geschirrs - ohne erzwungende Luftumwälzung und ohne erwärmte Luft - durchgeführt wird. Der erwärmte, zum Trocknen dienende Luftstrom soll zuerst auf die zu trocknenden Geschirrteile treffen und erst danach die Wasseroberfläche über dem Spülbehälterboden überstreichen, so daß die Trocknungsluft bereits beim Überstreichen des Geschirrs mit Feuchtigkeit gesättigt wird. Zur Durchführung dieses Verfahrens sind offenbar eine Zusatzheizung für die Trockenluft sowie ein Gebläse unabdingbar erforderlich.To reduce the heating energy for heating the washing liquors, a method for washing dishes is known (DE-OS 32 45 145), in which, after a last washing cycle carried out with heated water, heated air is passed over the dishes to dry and the water vapor from the Rinsing container is discharged in such a way that a rinse aid is added to the water in the last rinse, that the water is then only heated to a temperature of about 45 ° C, at which foaming of the rinse aid is safely avoided and that afterwards the heated air is passed through the rinsing container. According to this procedure, the amount of water required for distributing the rinse aid, in contrast to the above-mentioned rinsing methods usually used in the dishwashers on the market, is not raised to approx. 70 ° C, but only to a temperature of approx. 45 ° C heated up. After spraying the dishes with the rinse aid water heated to 45 ° C, a pumping process follows, at the beginning of which warm air should already be introduced. Without DE-OS 32 45 145 providing information about where the heating of the heated air to be introduced into the washing container when the rinse aid water is being pumped out, which is taken from the installation space of the dishwasher, it is emphasized that in this procedure for heating the air from the installation room until the dishes are blown dry requires a smaller amount of heat than is required to heat the water in the rinse cycle to a temperature of up to 70 ° C, if the dishes are dried in a static manner - without forced air circulation and without heated air - is carried out. The warmed, drying air stream should first hit the dishes to be dried and only then sweep the water surface over the bottom of the washing container so that the drying air is saturated with moisture as soon as the dishes are swept over. Additional heating for the dry air and a blower are obviously absolutely necessary to carry out this method.
Der Erfindung liegt die Aufgabe zugrunde, diesen zusätzlichen Aufwand bei einer Haushalt-Geschirrspülmaschine zu vermeiden und ein Verfahren anzugehen, wonach eine Haushalt-Geschirrspülmaschine mit wenig Aufwand energiesparend betrieben werden kann, ohne daß das Spül- und Trocknungsergebnis negativ beeinflußt wird.The invention has for its object to avoid this additional effort in a household dishwasher and to tackle a method according to which a household dishwasher operates with little effort to save energy can be without the washing and drying result is adversely affected.
Diese Aufgabe wird erfindungsgemäß bei einem Verfahren der eingangs genannten Art dadurch gelöst, daß die mit einem Klarspülmittel versetzte Klarspülwassermenge auf eine Temperatur von etwa 50°C aufgeheizt und dabei zur Beaufschlagung des Geschirrs über die Spritzeinrichtungen umgewälzt wird, daß nach Erreichen der Klarspülwassertemperatur die Klarspülwassermenge aus dem Spülbehälter abgepumpt wird und daß danach eine zum Aufheizen der Flüssigkeitsmenge in dem Teilprogramm Klarspülen vorgesehene Heizung taktweise bis zum Erreichen einer Trocknungstemperatur von etwa 60°C betrieben wird.This object is achieved in a method of the type mentioned in that the amount of rinse water mixed with a rinse aid is heated to a temperature of about 50 ° C and is circulated to the dishes on the sprayer that the rinse water volume after reaching the rinse water temperature is pumped out of the rinsing tank and that a heater provided for heating the amount of liquid in the rinse sub-program is then operated in cycles until a drying temperature of about 60 ° C. is reached.
Während bei den bekannten Haushalt-Geschirrspülmaschinen nach dem Programmabschnitt Klarspülen, wenn über die umgewälzte Klarspülwassermenge der zum Trocknen des Geschirrs erforderliche Wärmeübergang stattgefunden hat, die heiße Klarspülwassermenge mit einer Temperatur von etwa 70°C vom Spülbehälter in die Abwasserleitung fließt, wird nach der Erfindung die Umwelt bzw. das Ablaufkanalsystem lediglich mit einer ca. 50°C warmen Spülflotte belastet. Durch das Aufheizen auf die niedrigere Klarspülwasser-Temperatur ergibt sich eine Energie- und Zeitersparnis, wobei die eingesparte Heizzeit nach dem Abpumpen des Klarspülwassers beim taktenden Betrieb der Wasserheizung zusätzlich für das Trocknen zur Verfügung steht. Damit ist ohne Zusatzheizung und ohne Gebläse bei niedrigen Maschinenkosten eine verbesserte, effektive Geschirrtrocknung möglich, wobei die Endtemperatur beim Trocknen auf ca. 60°C gesenkt werden kann.While in the known household dishwashers according to the rinse-aid program section, when the heat transfer required to dry the dishes has taken place via the circulated amount of rinse-aid water, the hot amount of rinse-aid water flows from the washing-up container into the waste water line at a temperature of about 70 ° C., according to the invention The environment and the drainage system are only burdened with an approx. 50 ° C wash liquor. Heating to the lower rinse water temperature saves energy and time, and the heating time saved after pumping out the rinse water is also available for drying when the water heater is cycled. This enables improved, effective dish drying without additional heating and without a fan at low machine costs, whereby the final temperature during drying can be reduced to approx. 60 ° C.
Die vorbeschriebene Aufgabe wird nach einer vorteilhaften Verfahrensweise bei einem Verfahren der eingangs genannten Art dadurch gelöst, daß die Klarspülwassermenge während des Aufheizens auf etwa 50°C umgewälzt wird, daß die Zugabe des Klarspülmittels bei Erreichen der Klarspülflüssigkeitstemperatur erfolgt, daß nach der Klarspülmittelzugabe die Klarspülflüssigkeit weitere ca. zwei Minuten umgewälzt und dann abgepumpt wird und daß danach eine zum Aufheizen der Flüssigkeitsmenge in dem Teilprogramm Klarspülen vorgesehene Heizung bis zum Erreichen einer Trocknungsendtemperatur von etwa 60°C intermittierend betrieben wird.The above-described object is achieved according to an advantageous procedure in a method of the type mentioned at the outset in that the amount of rinse water is circulated during heating to about 50.degree is circulated for about two minutes and then pumped out, and then a heater provided for heating the amount of liquid in the rinse sub-program is operated intermittently until a final drying temperature of about 60 ° C. is reached.
Es ist ferner möglich, daß im Trocknen während des taktweisen Betriebes der Heizung zum Umwälzen der Trocknungsluft die Umwälzpumpe eingeschaltet wird.It is also possible that the circulation pump is switched on during drying during the cyclical operation of the heating for circulating the drying air.
In der Zeichnung ist in einem Schaubild mit über der Zeit aufgetragenem Temperaturverlauf ein das Reinigen, Zwischenspülen, Klarspülen und Trocknen umfassender Programmabschnitt dargestellt.In the drawing, a program section comprising cleaning, rinsing, rinsing and drying is shown in a diagram with the temperature profile plotted over time.
Der gezeichnete Temperaturverlauf beginnt im Teilprogramm Reinigen mit einem ansteigenden Temperaturabschnitt 1 bis zum Erreichen einer Reinigungstemperatur von ca. 65°. Während der Zeit für diesen Temperaturabschnitt ist die in Bodennähe des Spülbehälters der Haushalt-Geschirrspülmaschine angeordnete, z.B. aus einem schlaufenförmig verlegten Rohrheizstab bestehende elektrische Heizung eingeschaltet und die mit Reinigungsmittel versetzte Reinigungsflüssigkeit wird durch die laufende Umwälzpumpe über die Spritzeinrichtungen umgewälzt. Zum Zeitpunkt der Reinigungstemperatur von 65°C spricht ein Thermostat an und schaltet die Heizung ab, während die Umwälzpumpe noch einen Zeitabschnitt 2 weiterläuft und dann vor oder während des Abpumpens oder zusammen mit der Entleerungspumpe abgeschaltet wird. Es schließen sich beispielsweise ein erstes und ein zweites Zwischenspülen 3, 4 an.The temperature curve shown begins in the cleaning sub-program with an increasing temperature section 1 until a cleaning temperature of approx. 65 ° is reached. During the time for this temperature section, the one located near the bottom of the washing compartment of the domestic dishwasher is e.g. electrical heating consisting of a loop-shaped tubular heating element is switched on and the cleaning liquid mixed with cleaning agent is circulated by the running circulation pump via the spraying devices. At the time of the cleaning temperature of 65 ° C, a thermostat responds and switches off the heating, while the circulation pump continues to run for a period of 2 and is then switched off before or during pumping down or together with the drain pump. This is followed, for example, by a first and a second
