Abstract

The washing or rinsing machine is equipped with a washing or rinsing tub, with a circulating device for the heated water and with a housing preferably having a high degree of sealing relative to the atmosphere. So that a sudden pressure rise does not occur inside the machine when the circulating device is switched on, the circulating device is operated discontinuously in the start-up range by means of a control device, the respective switch-on time of the circulating device being small in relation to the subsequent intermission time, at least in the first part of the start-up range. As a result, an interval-like swirling of the cold air cushion located above the hot water together with hot water takes place, so that, with a rising temperature of the air, a steam/air mixture is obtained. As a result of the interval-like switch-ons of the circulating device in the start-up range preceding continuous operation, a sudden pressure rise inside the machine is prevented.

Description

Wasch- oder Spülmaschine Washing machine or dishwasher

Die Erfindung bezieht sich auf eine Wasch- oder Spülmaschine mit einem Wasch- oder Spülbottich, einer Umwälzvorrichtung für das aufgeheizte Wasser und einem vorzugsweise eine große Dichtigkeit gegenüber der Atmosphäre aufweisenden Gehäuse.The invention relates to a washing machine or dishwasher with a Washing or rinsing tub, a circulation device for the heated water and one preferably having a high level of impermeability to the atmosphere Casing.

Das in einer Wasch- oder Spülmaschine zur Reinigung verwendete heiße Wasser wird entweder in einem Wasch-oder Spülbottich aufgeheizt oder, sofern ein Heißwasseranschluß vorhanden ist, aus diesem Heißwasseranschluß dem Bottich zugeführt.The hot one used in a washing machine or dishwasher for cleaning Water is either heated in a washing or rinsing tub or, if one Hot water connection is available, fed from this hot water connection to the vat.

Wird das Wasser während des Aufheizens zum Waschen bzw. Spülen umgewälzt, so ergeben sich eine allmähliche Temperaturerhöhung und ein geringer Druckaufbau im Inneren des Bottichs. Wird dagegen das Wasser zunächst aufgeheizt oder bei einem Heißwasseranschluß nach dem Heißwassereinlauf in den Bottich mit dem Wasch- oder Spülvorgang kontinuierlich begonnen, so entsteht im Anlaufbereich der Umwälzvorrichtung ein plötzlicher Druckaufbau. Die Druckerhöhung ergibt sich dadurch, daß das kalte, oberhalb des heißen Wassersliegende Luftpolster plötzlich mit heißem Wasser durchwirbelt wird und somit ein erhitztes Dampf-Luft-Gemisch entsteht.If the water is circulated during heating for washing or rinsing, this results in a gradual increase in temperature and a low build-up of pressure inside the vat. If, on the other hand, the water is first heated or at one Hot water connection after the hot water inlet into the vat with the Washing or the rinsing process is started continuously, this results in the circulation device in the start-up area a sudden build-up of pressure. The increase in pressure results from the fact that the cold, Air cushions above the hot water suddenly swirled through with hot water and thus a heated steam-air mixture is created.

Durch diesen plötzlichen Druckaufbau werden die Wände des Wasch- oder Spülbottichs, Gehäusewände der Maschine und Dichtungen übermäßig belastet.Due to this sudden build-up of pressure, the walls of the washing or The washing tub, machine housing walls and seals are excessively stressed.

Der Erfindung liegt die Aufgabe zugrunde, eine Wasch-oder Spülmaschine der eingangs genannten Art so zu gestalten, daß die Beanspruchung der Maschinenteile beim Einschalten der Umwälzvorrichtung für das aufgeheizte Wasser klein gehalten und ein plötzlicher Druckaufbau im Inneren der Maschine vermieden wird.The invention is based on the object of a washing machine or dishwasher of the type mentioned to be designed so that the stress on the machine parts when switching on the circulation device for the heated water kept small and a sudden pressure build-up inside the machine is avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Umwälzvorrichtung im Anlaufbereich mittels einer Steuereinrichtung diskontinuierlich betrieben wird und zumindest im ersten Teil des Anlaufbereichs die jeweilige Einschaltdauer der Umwälzvorrichtung klein im Verhältnis zu der nachfolgenden Pausenzeit ist.This object is achieved according to the invention in that the circulating device is operated discontinuously in the start-up area by means of a control device and at least in the first part of the start-up range the respective duty cycle of the Circulation device is small in relation to the subsequent pause time.

Durch den diskontinuierlichen Betrieb der Umwälzvorrichtung im Anlaufbereich mit zunächst kleinen Einschaltzeiten, die mit größeren Pausenzeiten abwechseln, ergibt sich eine allmähliche Aufheizung des oberhalb des heißen Wassers liegenden kalten Luftpolsters. Nach einer ausreichenden Aufheizung dieses Luftpolsters kann dann die Umwälzvorrichtung kontinuierlich betrieben werden.Due to the discontinuous operation of the circulation device in the start-up area with initially short switch-on times that alternate with longer break times, this results in a gradual heating of the area above the hot water cold air cushion. After this air cushion has heated up sufficiently, then the circulation device can be operated continuously.

Bei einer Spülmaschine, bei der das aufgeheizte Spülwasser mittels einer Pumpe umgewälzt wird, wurde das intervallartige Durchwirbeln des kalten Luftpolsters oberhalb des heißen Wassers in der Weise durchgeführt, daß die Pumpe im Anlaufbereich mit Einschaltdauern von 0,3 sec. betrieben wurde, wobei zwischen den einzelnen Einschaltungen der Pumpe eine Pausenzeit von 2 sec. lag.In a dishwasher in which the heated rinse water is by means of a pump is circulated, the intermittent swirling of the cold air cushion carried out above the hot water in such a way that the pump is in the start-up area was operated with switch-on times of 0.3 sec., with between the individual switch-ons the pump had a pause time of 2 seconds.

Nach zwanzig Einschaltungen der Pumpe konnte mit dem kontinuierlichen Spülprozeß begonnen werden, ohne dass es zu einer übermäßigen Druckerhöhung im Inneren Maschine kam.After twenty starts the pump was able to continue with the The flushing process can be started without causing an excessive pressure increase inside Machine came.

Es ist zweckmäßig, im ersten TEil des Anlaufbereichs die jeweilige Einschaltdauer der Umwälzvorrichtung für das aufgeheizte Wasser kleiner als 0,6 sec. zu halten und zwischen zwei Einschaltungen eine Pausenzeit zu wählen, die ein vielfaches größer ist als die Einschaltdauer.In the first part of the start-up area, it is advisable to use the respective Duty cycle of the circulation device for the heated water is less than 0.6 sec. and to choose a pause time between two switch-ons is many times greater than the duty cycle.

Es ist bekannt, die Wasch- oder Spülmaschine mit selbsttätig öffnenden Ventilen oder Verschlüssen auszurüsten, durch die beim erfindungsgemäßen diskontinuierlichen Betrieb der Umwälzvorrichtung der langsame Druckaufbau im Wasch- oder Spülbottich im gleichen Maße mit dem Außendruck ausgeglichen werden kann.It is known that the washing machine or dishwasher with automatic opening Equip valves or closures by the discontinuous according to the invention Operation of the circulation device the slow pressure build-up in the washing or rinsing tub can be compensated to the same extent with the external pressure.
