Abstract

The charging instrument is intended particularly for miniature batteries, which are used in hearing aids, etc. The charger is not supplied from a fixed power source such as the mains. The charger is supplied with power from batteries which can be replaced when worn out. There is an electronic constant current circuit in the charger between the battery supply and the battery to be charged. There is also an indicator to check the conditions of the supply battery. The main components, the accumulator (1), charging batteries (2) current stabiliser (4) and indicator (5) are all housed in a single long cylindrical envelope.

Description

Lsadegerbit zum Aufladen von Akkumulatoren,Charging bit for charging accumulators,

insbesondere von Miniaturakkumulatoren.especially of miniature accumulators.

Die rfindung betrifft ein Ladegerät, insbesondere verwendet zur Aufladung von Miniaturakkumulatoren, die zum Betrieb von Hörgeräten Verwendung finden.The invention relates to a charger, especially used for charging of miniature accumulators that are used to operate hearing aids.

Der Zweck eines Ladegerätes besteht darin, entladene Akkumulatoren wieder aufzuladen.The purpose of a charger is to keep discharged batteries recharge.

us ist bekannt, zur Erfüllung dieses .rfordernisses Geräte zu verwenden, die nach Anschluß an des Lichtnetz, und entsprechender Umformung der eingespeisten Netzspannung, den für die Aufladung der Akkumulatoren notwendigen Strom abgeben.We are known to use devices to meet this requirement, after connection to the lighting network and corresponding transformation of the fed-in Mains voltage, deliver the current necessary to charge the batteries.

Um nun einen Akkumulator mit einem derartigen Ladegerät aufladen zu können, muß das Ladegerät viele Stunden an Lichtnet@ angeschlossen sein, bedingt durch dieerforderliche Aufladezeit des akkumulators.In order to now charge an accumulator with such a charger the charger must be connected to Lichtnet @ for many hours, conditionally by the required charging time of the accumulator.

Der Erfindung lag nun die Aufgabe zugrunde, ein Ladegerät zu schaffen, welches nicht aus einer @stationären Stromquelle wie z. B. das Lichtnetz, gespeist wird.The invention was now based on the object of creating a charger, which does not come from a stationary power source such as B. the lighting network, fed will.

Diese Aufgabe wird erfindungsgemäß ladurcn gelöst, daß die erforderliche Stromquelle in Form von Batterien auswechselbar nach deren Erschöpfung, mit in das Ladegerät eingebaut wird.This object is achieved according to the invention that the required Power source in the form of batteries replaceable after they are exhausted, with in the Charger is installed.

Um mit einem derartigen Ladegerät eine, über die gesamte Lebensdauer der batterie gleichmäßige Aufladezeit des zu ladenden Akkus zu erhalten, wird zwischen Batterie und Akku, innerhal@ des Gerätes, eine elektronische Konstantstromschaltung eingebaut.To be able to use such a charger over the entire service life the battery to get even charging time of the battery to be charged is between Battery and accumulator, inside the device, an electronic constant current circuit built-in.

b;a den Batteriezustand feststellen zu können, wird eine Anzeige eingebaut.b; a to be able to determine the battery condition, a display is built in.

Der mit der rfindllllg erzielte Vorteil besteht insbesondere darin, daß der im Verwendungsbeispiel angeführte Hörgerätetrager seinen A Akkumulator jederzeit und überall aufladen kann, ohne an eine stationäre Stromquelle gebunden zu sein, welches bei der normalerweise benötigten Aufladezeit von 12 bis 14 Stunden pro Akku, oftmals schon im Alltag, erstrecht aber auf teisen, zu Problemen führen kann.The advantage achieved with the rfindllllg is, in particular, that the hearing aid wearer listed in the example of use has his A accumulator at any time and can charge anywhere without being tied to a stationary power source, which with the normally required charging time of 12 to 14 hours per battery, often in everyday life, but especially in the long run, can lead to problems.

Die Zeichnung zeigt: Unter Figur 1 das Grundprinzip des Ladegerätes, wobei 1 den zu ladenden Akku, 2 die den Ladestrom liefernde Batterie, und 3 einen strombegrenzenden Widerstand darstellt.The drawing shows: Under Figure 1 the basic principle of the charger, where 1 is the battery to be charged, 2 is the battery supplying the charging current, and 3 is a represents current-limiting resistance.

Unter Figur 2 das erweiterte Ladegerät, wobei dann L die Stromstabilisierung und 5 die Zustandsanzeige der Batterie symbolisiert.Under Figure 2 the extended charger, where L then the current stabilization and 5 symbolizes the status display of the battery.

Unter Figur 3 ist die mögliche Ausführung eines derartigen Ladegerätes skizziert.Under Figure 3 is the possible design of such a charger outlined.

Anmerkung zu@ @nor Patentanmeldung Auf den ersten Blick scheint es nur zu logisch zu sein, ein kleines Gerät statt aus dem Lichtnetz mit einer Batterie zu betreiben, es wird doch vielfältig in der Unterhaltungselektronik so gemacht.Note on @ @nor patent application At first glance it seems only to be logical, a small device instead of the mains with a battery to operate, it is done in a variety of ways in entertainment electronics.

In meiner fast 2Ojährigen Berufspraxis in Zusammenhang mit Hörgeräten ist mir jedoch noch niemals ein batteriebetriebenes Ladegerät begegnet.In almost 20 years of professional experience in connection with hearing aids however, I have never come across a battery-operated charger.

Es erscheint wohl Jedem Techniker unlogisch, einen Akku mit Hilfe einer Batterie aufzuladen. Eingehende Versuche ergaben dann aber eine interessante Lösung.It seems illogical to every technician to use a battery a battery. However, detailed attempts then resulted in an interesting one Solution.

Mit 2 Stück Mignon Batterien kann ein Akku DK 20 etwa 50mal aufgeladen werden, und unter Zwischenschaltung einer Stronistabilisierung können die Batterien bis zur völligen Frschöpfung einen genau so gleichmäßigen Strom abgeben, wie bekannte netzbetriebene Ladegeräte.A DK 20 rechargeable battery can be charged about 50 times with 2 Mignon batteries and with the interposition of a current stabilization, the batteries emit a current that is just as steady as known mains operated chargers.
