Abstract

In the case of a device for determining the moisture content in babies' nappies while they are being worn, in the case of which a lossy tuned circuit is located in the nappy, the loss resistance of which tuned circuit is determined, without making contact, by means of an inductively coupled measurement part, the loss resistance of the tuned circuit is dependent on the moisture content of the wet absorbent material in the nappy.

Description

einrichtung zum Bestimmen des Feuchtigkeitsgehalts indevice for determining the moisture content in

Sabynöschenwindeln während des Tragens Die Erfindung betrifft eine Schaltung zur Bestimmung des Feuchtigkeitsgehalts in Babywindeln während des Tragens laut Oberbegriff des PatentansprLchs.Sabynose diapers during wear. The invention relates to a Circuit for determining the moisture content in baby diapers while they are being worn according to the preamble of the patent claim.

Es ist Aufgabe der Erfindung, eire Meßschaltung zur Bestimmung des Feuchtigkeitsgehalts im Nässespeichermaterial von Babywindeln (tdegwerfhöschenwindeln) festzulegen, daß sie einerseits kostengünstig ist und andererseits die berüh; rungslose unmittelbare Bestimmung des Feuchtigkeitsgehalts ermöglicht.It is the object of the invention to provide a measuring circuit for determining the Moisture content in the moisture storage material of baby diapers (tdegwerfhöschenwindeln) specify that it is on the one hand inexpensive and on the other hand the touch; impotent enables immediate determination of the moisture content.

Diese Aufgabe wird ausgehend von einer Schaltung laut Oberaegriff des Patentanspruchs durch dessen kennzeichnende Verkmale gelöst.This task is based on a circuit according to the general concept of the claim solved by its characteristic features.

ei ier erfindungsgemäßen Schaltung wird auf der Resonanzfrequenz io des Schwingkreises, cessen Werlustwiderstand R, welcher seinerseits direkt abhängig vom Feuchtigkeitsgehalt im Nässespeicher ist, berührungslos bestimmt. Der Schwingkreis, welcher z.B. an der bauchseite der Babywindel in diese eingearbeitet ist, wird zur Bestimmung des Feuchtigkeitsgehalts im Inneren der windel, von außen durch induktive Ankopplung erregt. Die dabei notwendige Erregungsenergie ist ein Maß für den mittleren Feuchtigkeitsgehalt m Nässespeichermaterial.Ei ier circuit according to the invention is at the resonance frequency io of the oscillating circuit, measure the Werlust resistance R, which in turn is directly dependent of the moisture content in the moisture reservoir is determined without contact. The oscillating circuit, which is worked into the baby diaper on the stomach side, for example, becomes the Determination of the moisture content inside the diaper, from the outside by inductive Coupling excited. The necessary excitation energy is a measure of the average Moisture content in moisture storage material.

Die Erfindung wird im Folgenden anhand einer schematischen Zeichnung an einem Ausführungsbeisaiel näher erläutert.The invention is explained below with reference to a schematic drawing explained in more detail using an exemplary embodiment.

Die Figur 1 zeigt das Prinzipschaltbild einer erfindungsgemäßen Meßschaltung, mit einem in der Babywindel eingearbeiteten, verlustbehafteten Schwingkreis1, der zur Bestimmung des jeweiligen Werlustwiderstands R, induktiv an einen auf der selben Resonanzfrequenz O erregten Schwingkreis 2 im Meßteil 3 angekoppelt wird.FIG. 1 shows the basic circuit diagram of a measuring circuit according to the invention, with a lossy oscillating circuit1 incorporated into the baby diaper, the to determine the respective Werlust resistance R, inductively to one on the same Resonant frequency O excited resonant circuit 2 is coupled in the measuring part 3.

Die von seiten der Oszillatorschaltung 4 zur Erlangung einer bestimmten Schwingungsamplitude auf der Frequenz wO aufzubringende Energie ist um so höher, je höher der Feuchtigkeitsgehalt im Nässespeichermaterial ist.On the part of the oscillator circuit 4 to obtain a certain Vibration amplitude at the frequency where the energy to be applied is higher, the higher the moisture content in the moisture storage material.

it einem einstellbaren Widerstand 5 kann diese Energiezufuhr derart dosiert werden, daß eine Auswerteschaltung 6 bei Unterschreitung der jeweils mindestens notwendigen Erregungsenergie des Schwingkreises 1 , ein optisches und akustisches Signal an der Meldeeinrichtung 7 auslöst.With an adjustable resistor 5, this energy supply can be be dosed that an evaluation circuit 6 when the respective at least necessary excitation energy of the oscillating circuit 1, an optical and acoustic Signal at the reporting device 7 triggers.

Oie Figur 2 zeigt als Beispiel den Schwingkreis 1, eingebettet in eine Babywindel mit einer Auslegung der metallischen Leiter 2,3 und 4, welche über die elektrische Leitfähigkeit des feuchten Nässespeichermaterials 5, den feuchtigkeitsabhängigen Werlustwiderstand R aus Figur 1 bilden. Die Schwingkreiskapazität wird durch die beiden Kondensatoren 6 und 7 gebildet, welche parallel zur Schwingkreisspule 8 liegen.As an example, FIG. 2 shows the resonant circuit 1, embedded in a baby diaper with a design of the metallic conductors 2, 3 and 4, which over the electrical conductivity of the moist moisture storage material 5, the moisture-dependent Form the value resistor R from FIG. The resonant circuit capacity is determined by the two capacitors 6 and 7, which are parallel to the resonant circuit coil 8.
