Abstract
Haushaltgerät, insbesondere Geschirrspüler, mit einem Flüssigkeitskreislauf, der eine Umwälzpumpe aufweist, wobei in der Umwälzpumpe eine Heizung integriert ist, dadurch gekennzeichnet, dass die Heizung einen PTC-Widerstand (8) als Heizelement aufweist.Household appliance, in particular Dishwasher, with a fluid circuit, the one circulating pump wherein, in the circulation pump a heater is integrated, characterized in that the heater having a PTC resistor (8) as a heating element.
Description
Die Erfindung betrifft ein Haushaltgerät, insbesondere einen Geschirrspüler, mit einer Umwälzpumpe, in welche eine Heizung integriert ist.The The invention relates to a domestic appliance, in particular a dishwasher, with a circulation pump, in which a heater is integrated.
Aus
Die Verwendung derartiger Heizungen mit entsprechenden Temperaturreglern bzw. -begrenzern macht die Konstruktion des Geräts jedoch relativ aufwändig und somit teuer.The Use of such heaters with appropriate temperature controllers However, the construction of the device is relatively complex and thus expensive.
Es stellt sich deshalb die Aufgabe, ein Gerät bereitzustellen, welches einfacher in seiner Konstruktion ist.It Therefore, the task is to provide a device which is simpler in its construction.
Diese Aufgabe wird vom Haushaltgerät gemäss Anspruch 1 erfüllt.These Task is from the household appliance according to Claim 1 satisfied.
Demgemäss wird als Heizelement in der Heizung ein PTC-Widerstand verwendet. Derartige Widerstände erhöhen ihren elektrischen Widerstandswert, wenn ihre Temperatur ansteigt. Somit kann eine inhärente Selbstregelung bzw. Temperaturbegrenzung erzielt werden, da der PTC-Widerstand mit zunehmender Temperatur weniger Leistung verbraucht.Accordingly as a heating element in the heater uses a PTC resistor. such resistors increase their electrical resistance as their temperature rises. Thus, an inherent Self-regulation or temperature limitation can be achieved since the PTC resistor with increasing temperature consumes less power.
Weitere bevorzugte Ausführungen der Erfindung ergeben sich aus den abhängigen Ansprüchen sowie aus der nun folgenden Beschreibung anhand der Figuren. Dabei zeigen:Further preferred embodiments The invention will become apparent from the dependent claims and from the description below with reference to the figures. Showing:
Wie bereits erwähnt, bezieht sich die Erfindung auf ein Haushaltgerät, vorzugsweise einen Geschirrspüler. Denkbar ist der Einsatz der Erfindung jedoch z.B. auch in einer Waschmaschine.As already mentioned, The invention relates to a household appliance, preferably a dishwasher. Conceivable however, the use of the invention is e.g. also in a washing machine.
