Description

Die Erfindung bezieht sich auf eine Schaltungsanordnung für eine induktive Energieübertragung von einem Speisenetz auf einen Verbraucher mit einem primärseitig an das Speisenetz und sekundärseitig an den Verbraucher anschließbaren Transformator, dessen Primär- und Sekundärspule voneinander räumlich trennbar angeordnet und ausgebildet sind.The invention relates to a circuit arrangement for inductive energy transmission from a feed network to a consumer with a transformer that can be connected on the primary side to the feed network and on the secondary side to the consumer, the primary and secondary coils of which are arranged and designed to be spatially separable from one another.

Eine derartige Schaltungsanordnung ist z. B. durch die EP-OS 0 352 592 bekannt geworden. Bei der bekannten Bauart handelt es sich um ein Stromversorgungsgerät für elektronische Einrichtungen, wobei der Kern des Netztransformators in einer zwischen der Primär- und Sekundärseite liegenden Ebene auftrennbar ist. Dabei ist diese Anordnung so getroffen, daß der die Primärwicklung tragende Teil des Transformatorkernes auf Führungselementen senkrecht zu der Trennebene bewegbar ist. Dieses bekannte Stromversorgungsgerät kann in einfacher Weise auch in explosionsgefährdeter Umgebung mit dem Speisenetz verbunden oder von dem Netz getrennt werden, ohne daß beim Schalten Funkenbildung auftritt.Such a circuit arrangement is such. B. become known from EP-OS 0 352 592. The known design is a power supply device for electronic devices, the core of the network transformer being separable in a plane lying between the primary and secondary side. This arrangement is such that the part of the transformer core carrying the primary winding can be moved on guide elements perpendicular to the parting plane. This known power supply device can be connected to the feed network or disconnected from the network in a simple manner even in a potentially explosive environment, without sparking occurring during switching.

Der Erfindung liegt die Aufgabe zugrunde, eine Schaltungsanordnung der eingangs genannten Art zu vereinfachen und zu verbessern, so daß sie insbesondere bei einer Gerätetechnik verwendbar ist, bei der der zu speisende Verbraucher auf einem beweglichen Bauteil angeordnet ist, ohne daß dabei eine Kabel- oder Kontaktverbindung erforderlich ist.The invention has for its object to simplify and improve a circuit arrangement of the type mentioned, so that it can be used in particular in a device technology in which the consumer to be fed is arranged on a movable component, without the need for a cable or contact connection.

Diese Aufgabe wird gemäß der Erfindung bei einer Schaltungsanordnung der eingangs genannten Art dadurch gelöst, daß die beiden Spulen als ein ineinander greifendes Tauchspulensystem ausgebildet sind. Dieses Tauchspulensystem besteht aus einer ersten Spule, die vorzugsweise als mit dem Speisenetz verbindbare Primärspule ausgebildet ist, und aus einer zweiten Spule, nämlich der Sekundärspule, die beim Ineinandergreifen in die Primärspule eintaucht und somit eine Energieübertragung auf die Sekundärspule und damit auf den mit der Sekundärspule verbundenen Verbraucher ermöglicht. Ein Tauchankerspulensystem der genannten Art ermöglicht eine einwandfreie Energieübertragung, ist einfach herstellbar und kann in verschiedenen Geräten, auch bei beengten Platzverhältnissesn, leicht angebracht werden.This object is achieved according to the invention in a circuit arrangement of the type mentioned in the introduction in that the two coils are designed as an interlocking moving coil system. This moving coil system consists of a first coil, which is preferably designed as a primary coil that can be connected to the feed network, and a second coil, namely the secondary coil, which plunges into the primary coil when it meshes with one another and thus transmits energy to the secondary coil and thus to the one with the secondary coil connected consumers. A submersible armature coil system of the type mentioned enables flawless energy transfer, is easy to manufacture and can be easily installed in various devices, even in confined spaces.

Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß die Primärspule ortsfest in einem Gerät, z. B. in einem Haushaltgerät, und die Sekundärspule an einem mit dem Gerät lösbar verbindbaren oder an dem Gerät beweglich verbundenen Bauteil angeordnet ist. Diese Bauweise ermöglicht eine einfache Energieübertragung von dem stationären Gerät über das Tauchspulensystem auf den Verbraucher, der auf dem beweglichen Bauteil angeordnet ist.An advantageous embodiment of the invention is characterized in that the primary coil is stationary in a device such. B. in a household appliance, and the secondary coil is arranged on a detachably connectable to the device or movably connected to the device component.

Damit ist es möglich, den Spülmittelkasten selbst zu elektrifizieren, ohne daß dabei eine Kabel- oder Kontaktverbindung erforderlich ist. Damit können in dem Spülmittelkasten Anzeigeelemente, z. B. LED's, Schalter, Sensoren oder kleine motorische bzw. magnetische Antriebe, z. B. Ventile, eingebaut werden. Um den Wirkungsgrad der Energieübertragung zu erhöhen, sind die Spulen vorzugsweise mit Leitblechen versehen.A preferred embodiment is characterized in that the primary coil in the insertion area of the detergent drawer of a household appliance and the secondary coil is attached to the detergent drawer itself and that the as Immersed secondary coil immerses in the primary coil when inserting the detergent dispenser.

Es ist ferner möglich, je nach Kundenwunsch verschiedene Spülmittelkästen zu bauen, die austauschbar sind und jeweils mit den entsprechenden Bauelementen versehen sind. So kann z. B. ein Spülmittelkasten für Waschpulver oder ein Spülmittelkasten für Flüssigwaschmittel mit Vorratstanks aufgebaut werden, aus denen nur die benötigte Waschmittelmenge entnommen wird. Desgleichen kann ein Spülmittelkasten hergestellt werden für verschiedene flüssige Waschkomponenten, deren Mischung automatisch erfolgt, und zwar mit Hilfe der am Spülmittelkasten angebrachten erforderlichen Steuerglieder, die mittels der erfindungsgemäßen Schaltungsanordnung von der zentralen Steuereinheit gesteuert werden.Instead of a dispenser box, doors or flaps can be provided according to the invention, which are provided with the secondary coil and also contain the above-mentioned components. It is also possible, depending on the customer's request, to build various detergent boxes which are interchangeable and each provided with the appropriate components. So z. B. a detergent box for washing powder or a detergent box for liquid detergent can be built with storage tanks, from which only the required amount of detergent is removed.
