Abstract
Description
Die vorliegende Erfindung betrifft eine von einem Elektromotor, insbesondere einem elektronisch kommutierten Gleichstrommotor (EC-Motor), betriebene Pumpe zur Versorgung einer Heizungs- oder Klimaanlage eines Gebäudes, mit einem Gehäuse, umfassend ein Pumpengehäuse, in dem ein Laufrad angeordnet ist, und umfassend ein Motorgehäuse, in dem elektrische und/oder elektronische Komponenten zum Betrieb des Motors angeordnet sind.The present invention relates to one of an electric motor, in particular one electronically commutated direct current motor (EC motor), operated pump for Supply of a heating or air conditioning system for a building, with a housing, comprising a pump housing in which an impeller is arranged, and comprising a motor housing in which electrical and / or electronic components for Operation of the engine are arranged.
Derartige Heizungspumpen sind hinlänglich bekannt. Sie versorgen zumeist als Teil einer Zentralheizung das Heizungssystem von einer zentralen Stelle aus. Diese Pumpen haben im allgemeinen eine Leistungsaufnahme von weniger als 100 Watt und beziehen ihren Strom aus dem Netz. Ein geeigneter Netzanschluß steht für gewöhnlich an zentraler Stelle zur Verfügung. Seit kurzer Zeit sind auch sogenannte "dezentrale" Pumpen bekannt, die jeweils nur einen einzelnen Heizkörper oder aber wenigen in einem Raum angeordneten Heizkörpern zugeordnet sind und nur deren Versorgung mit Heizmedium bewerkstelligen. Diese Pumpen können wegen der geringeren Anforderungen von entsprechend kleinerer Leistung sein. Sie werden ebenfalls über das Spannungsnetz des Gebäudes versorgt.Such heating pumps are well known. They mostly supply as part central heating the heating system from a central point. This Pumps generally consume less than 100 watts and get their electricity from the grid. A suitable network connection stands for usually available at a central location. Recently, so-called "Decentralized" pumps known, each only a single radiator or are assigned to a few radiators arranged in a room and only theirs Carry out supply of heating medium. These pumps can because of lower requirements of correspondingly lower performance. you will be also supplied via the building's power grid.
Nachteilig an den bislang bekannten Pumpen ist jedoch, daß die Stromversorgung über Leitungen geschieht, die zu den dezentralen Pumpen hin verlegt werden müssen. Diese Leitungen, die mitunter über relativ weite Strecken verlegt werden, beeinträchtigen den optischen Eindruck des Gesamtsystems aus Heizkörper und daran angeschlossener Pumpe. Sie tragen außerdem dazu bei, daß diese dezentralen Pumpen unkomfortabel in ihrer Wartung und Handhabung sind.A disadvantage of the pumps known to date, however, is that the power supply is done via lines that are routed to the decentralized pumps have to. These lines, which are sometimes laid over relatively long distances, affect the visual impression of the overall system of radiators and connected pump. They also contribute to this decentralized pumps are uncomfortable in their maintenance and handling.

Der erfindungsgemäße Gedanke liegt darin, die Energieversorgung der Pumpe allein durch eine mit der Pumpe mechanisch verbundene Batterie zu bewerkstelligen. Das garantiert zumindest für die Lebensdauer der Batterie oder der Batterien eine vollständige Unabhängigkeit von einer externen Stromversorgung. Die Pumpe ist somit bezüglich ihrer Versorgung autark. Auf diese Weise können die störenden Versorgungskabel vermieden werden und die Pumpe kann flexibel eingesetzt und komfortabel montiert werden. Die Erfindung manifestiert sich darin, daß im oder am Gehäuse, also an einer definierten Stelle an der Pumpe, eine Batterie zur Hauptversorgung des Motors und, falls es sich um eine geregelte Pumpe handelt, der den Motor steuernden Elektronik angeordnet ist. Die Batterie ist also nicht lediglich zur Notversorgung vorgesehen. Selbstverständlich ist die Elektrik respektive die Elektronik dem Umstand der im Vergleich zum Netz reduzierten Spannung von beispielsweise 12 V oder 24 V angepaßt.The idea according to the invention lies in the energy supply of the pump alone by a battery mechanically connected to the pump. The guarantees at least for the life of the battery or batteries complete independence from an external power supply. The pump is thus self-sufficient with regard to their care. This way, the distracting Supply cables can be avoided and the pump can be used flexibly and can be installed comfortably. The invention manifests itself in that in or on Housing, i.e. at a defined point on the pump, a battery for Main supply of the motor and, if it is a regulated pump, the electronics controlling the motor is arranged. So the battery is not intended only for emergency care. Of course, the electronics are respectively the electronics the circumstance of the reduced voltage of adapted for example 12 V or 24 V.
Besonders vorteilhaft läßt sich die Erfindung bei Pumpen einsetzen, deren Leistungsaufnahme mit weniger als 10 Watt, insbesondere weniger als 2 Watt, vergleichsweise gering zu üblichen Heizungspumpen ist. Ein derartiger Leistungsbereich ist gerade bei den erwähnten dezentralen Pumpen üblich, die jeweils nicht viel mehr als nur einen Heizkörper versorgen müssen. Eine solche Pumpe wird dementsprechend im Vor- oder Rücklauf in unmittelbarer Nähe oder direkt an dem Wärmetauscher, insbesondere dem Heizkörper, angebracht. So kann die Pumpe die Stelle und die Rolle des Heizkörperventils übernehmen. Da in diesem Fall die Pumpe in gewisser Weise in den Heizkörper integriert ist, bezieht sich die Erfindung auf das gesamte System aus Wärmetauscher der daran angebrachten Pumpe.The invention can be used particularly advantageously in pumps whose Power consumption with less than 10 watts, especially less than 2 watts, is comparatively low compared to conventional heating pumps. Such one Performance range is common especially with the decentralized pumps mentioned do not have to supply much more than just a radiator. Such Accordingly, the pump is in the flow or return in the immediate vicinity or directly attached to the heat exchanger, especially the radiator. So can the pump takes the place and role of the radiator valve. Because in this If the pump is integrated in the radiator to a certain extent, it refers to the Invention on the entire system of heat exchangers attached to it Pump.

Derartige auch als Akkus bezeichnete wiederaufladbare Batterien sind mit relativ hohen Kapazitäten in kleiner Bauweise zu ständig sinkenden Kosten kommerziell erhältlich. Vorteilhafter Weise werden die bekannten Ni/Cd Akkus oder Litium lonen Akkus eingesetzt, die sich durch ihre lange Lebensdauer und ihre Zuverlässigkeit bei geringem Preis auszeichnen. Es kann auch vorteilhaft sein, andere moderne Akkus mit hoher Kapazität bei geringer Baugröße zu verwenden. Der Akku könnte in einer besonderen Ausführungsform stationär montiert sein, so daß der Nutzer die installierte Pumpe für eine gewisse Ladezeit über ein Kabel mit einer externen Spannungsquelle unter Zwischenschaltung eines Ladegerätes verbinden muß, um die Batterie aufzuladen. Die zu verwendenden Akkus haben vorteilhafter Weise eine Kapazität von mindestens 20 Ah, so daß Pumpen bei 1 Watt Leistungsaufnahme mindestens 200 Stunden laufen können. Unter dem Aspekt, daß die Pumpen eine moderne und auf maximale Energieeinspaarung ausgelegte Steuerelektronik haben, kann die Betriebsdauer um einen entsprechenden Faktor verlängert werden.It is certainly particularly advantageous to design the battery to be rechargeable.

Der Nutzer kann dann jederzeit nach Bedarf die Batterie austauschen. Ein Servicetechniker ist dazu nicht notwendig. Weiterhin vorteilhaft ist es, wenn die Batterie in einem solchen austauschbaren Akkupaket angeordnet ist, das als kompaktes Bauteil einfach auf das Motorgehäuse aufsteckbar ist, wobei sich beim Aufstecken die Kontakte zum Motor automatisch schließen. Wie vom Einsatz bei Akkuschraubern bekannt, sind derartige Akkupakete von jedermann handhabbar. Um eine Gefährdung der Nutzer durch eine im Generatorbetrieb laufende Pumpe ausschließen zu können, ist bei der Konzeption der Kontakte selbstverständlich darauf zu achten, daß diese nicht frei zugänglich sondern abgedeckt sind. Das Akkupaket kann dann in vorteilhafter Weise in eine entsprechende über die Netzspannung versorgte Ladestation eingesteckt und aufgeladen werden. Die an zentraler Stelle aufgestellte Ladestation kann dabei die Batterien mehrerer Pumpen aufnehmen und laden.However, for simple and convenient handling, it is advantageous if the (rechargeable) battery, which consists of a pack of several individual batteries, as well as accessible and detachably attached in or on the motor housing.

Bei einer besonders vorteilhaften Ausführungsform wird der Akku zumindest teilweise von einer insbesondere in ihrer Stellung zum Licht justierbaren Solarzelle aufgeladen, die mit dem Akku verbunden ist. Auch wenn diese Energiequelle nicht die vollständige Aufladung bewerkstelligen kann, so trägt die dennoch in mitunter starkem Maße dazu bei. Wegen der großen zur Verfügung stehenden Fläche und der Möglichkeit der geschickten Integration in das Design ist es besonders vorteilhaft, die Solarzelle an der Fläche des Wärmetauschers, insbesondere des Heizkörpers, anzubringen und über ein Kabel mit der Batterie zu verbinden. Mit den heute bekannten leistungsfähigen Solarkollektoren, die eine hohe Ausbeute bei relativ geringer Fläche garantieren, ist eine derartige zusätzliche Stromversorgung einfach realisierbar. Die Möglichkeit der Justierung erlaubt es dabei , die Lichtquelle, die sowohl eine Lampe als auch die Sonne sein kann, optimal auszunutzen.In a particularly advantageous embodiment, the battery is at least partially from a solar cell that is adjustable in particular in relation to the light charged, which is connected to the battery.
