Abstract

This electronic apparatus is particularly suitable as a water-level signalling device for bath tubs. The level of the bath water and hence possible overflowing are indicated in good time by means of an acoustic signal. This is achieved by means of a sensor having an integrated suction cup which can be fitted at the desired level on the bath-tub wall. The sensor, which determines the water level, is connected to the signalling device by means of a two-core cable. The location of the signalling device is variable by means of the cable, and the possibility is thus provided of monitoring the water flowing in in any desired space.

Description

Beschreibung description

1 Die Erfindung betrifft einen Akustischen Wasserstandsmelder, dessen Sensor (Abb. 1 und 2j aus zwei Messingelektroden (1) und einem Saugnapf (2i, eingegossen in einen Kunststoffblock (3) besteht. Der Sensor ist über ein flexibles Kabel (4) mit dem Melder verbunden. Das 2 Gehäuse des Melders (Abb. 3) ist so konstruiert, daß das Kabel (4) um den Melderfuß (5) aufgewickelt und der Sensor in einer dafür vorgesehenen Aussparung (6) aufbewahrt werden kann. Im Meldergehäuse (Abb. 4) befindet sich die elektronische Steuerung auf einer gedruckten Schaltung (8), die Batterie in einer dafür 3 vorgesehenen Kammer (9) und ein Lautsprecher (10). Die Signalverstärkung im Melder erfolgt durch Darlington Verstärker und für die Tonerzeugung findet ein A-stabiler Multivibrator Anwendung, dessen Ausgang verstärkt wird und auf einem Lautsprecher liegt. Als 4 Stromquelle dient eine 9-V Monozelle. Durch einen Schalter (7) ist die Batterie vom Stromkreis zu trennen.1 The invention relates to an acoustic water level detector, the Sensor (Fig. 1 and 2j made of two brass electrodes (1) and a suction cup (2i, cast in) in a plastic block (3). The sensor is via a flexible cable (4) connected to the detector. The 2 housing of the detector (Fig. 3) is constructed in such a way that that the cable (4) wound around the detector base (5) and the sensor in one for it provided recess (6) can be stored. Located in the detector housing (Fig. 4) the electronic control is on a printed circuit (8), the battery in a chamber (9) provided for this purpose 3 and a loudspeaker (10). The signal amplification Darlington amplifiers are used in the detector and a A-stable multivibrator application, the output of which is amplified and on a Speaker lies. A 9 V mono cell serves as the 4 power source. Through a switch (7) the battery must be disconnected from the electrical circuit.

Der Sensor wird entsprechend der gewünschten Flüssigkeitshöhe an der glatten Innenseite des Behälters mittels Saugnapf festgedrückt. The sensor is activated according to the desired liquid level the smooth inside of the container with a suction cup.

5 Steigt die Flüssigkeit im Behälter bis zum Sensor an, schließt sich ein Stromkreis über die Elektroden zur Basis des ersten Transistors. Der Transistor steuert durch. Das Signal wird über weitere Stufen verstärkt und steuert den Multivibrator an. Der Multivibrator 6 schwingt. Die Schwingungen werden verstärkt und durch den Lautsprecher in akustische Schwingungen umgewandelt.5 If the liquid in the container rises to the sensor, it closes a circuit across the electrodes to the base of the first transistor. The transistor steers through. The signal is amplified through further stages and controls the multivibrator at. The multivibrator 6 oscillates. The vibrations are amplified and through the Loudspeaker converted into acoustic vibrations.

Die verwandte elektronische Steuerung (Abb. 3) entspricht dem heutigen Stand der Technik. The related electronic control (Fig. 3) corresponds to the current one State of the art.

7 Der Vorteil dieses Gerätes ist derart, daß sich Sensor und Melder in getrennten Räumen befinden können. Wenn z.B. in der Badewanne Wasser einläuft, kann sich der Melder im Wohnraum befinden und würde akustisch anzeigen, wenn das Wasser die gewünschte Höhe 8 erreicht hat.7 The advantage of this device is that the sensor and detector can be located in separate rooms. If, for example, water runs into the bathtub, the detector can be located in the living room and would indicate acoustically if that Water has reached the desired height 8.
