Zur Aufnahme einer Flüssigkeit bestimmter Metallbehälter.Metal containers designed to hold a liquid.
Die Erfindung bezieht sich auf einen zur Aufnahme einer Flüssigkeit bestimmten Metallbehälter mit einem mit einer Metallhülle versehenen Temperaturfühler, der durch die Behälterwand nach innen ragt und eine Elektrode vom Behälter isoliert in diesem angeordnet ist.The invention relates to a metal container intended to hold a liquid, having a with a Metal sheathed temperature sensor, which through the The container wall protrudes inwards and an electrode is arranged in this isolated from the container.
Bei zur Aufnahme von Flüssigkeiten bestimmten Metallbehältern besteht das Bedürfnis, einmal die Temperatur der im Behälter angeordneten Flüssigkeit zu messen und zum anderen festzustellen, ob Flüssigkeit im Behälter vorhanden ist und/oder welche elektrische Leitfähigkeit diese hat. Die Temperaturmessung kann mit einem in der Behälterwand angeordneten Temperaturfühler vorgenommen werden, während das Vorhandensein von Flüssigkeit im Behälter durch Messung der elektrischen Leitfähigkeit zwischen der Behälterwand und einer davon isoliert im Behälter angeordneten Elektrode vorgenommen werden kann. Solche Vorrichtungen werden beispielsweise bei elektrischen Haushaltsgeräten wie Waschmaschinen und Geschirrspülmaschinen benötigt, bei denen es erforderlich ist, festzustellen, ob sich Flüssigkeit im Behälter befindet, um ein Einschalten der Heizung bei leerem Behälter zu verhindern und um die Temperatur der Waschflüssigkeit festzustellen, was zum Ein- und Ausschalten der Heizung dient. Ggfs. kann mittels der Leitfähigkeitsmessung auch die Härte desFor metal containers designed to hold liquids there is a need to measure the temperature of the liquid arranged in the container and to others determine if there is liquid in the container is and / or what electrical conductivity this Has. The temperature can be measured with one in the container wall arranged temperature sensor can be made while the presence of liquid in the container by measuring the electrical conductivity between the Container wall and an electrode arranged therefrom isolated in the container can be made. Such devices are for example in electrical household appliances like washing machines and dishwashers needed, where it is necessary to determine whether there is liquid in the container in order to prevent the heating from being switched on when the container is empty and in order to determine the temperature of the washing liquid what is used to switch the heating on and off. Possibly. the hardness of the

Wassers festgestellt werden, so daß die Waschmittel- oder Spülmittelzugabe entsprechend dosiert werden kann.Water can be determined so that the addition of detergent or detergent can be dosed accordingly.
Zur Temperaturmessung werden üblicherweise Temperaturfühler verwendet, die mit einer MetaLlhülle versehen sind, und die durch die Behälterwand nach innen ragen.Temperature sensors are usually used for temperature measurement are used, which are provided with a metal cover and which protrude inward through the container wall.
Zur Leitfähigkeitsmessung muß eine von der Behälterwand isoliert angeordnete Elektrode vorgesehen sein.In order to measure the conductivity, one of the insulated electrode can be provided.
Aufgabe der Erfindung ist es, eine solche Anordnung zu vereinfachen und zu verbilligen.The object of the invention is to simplify such an arrangement and cheaper.
Dies wird gemäß der Erfindung dadurch erreicht, daß die Metallhülle des Temperaturfühlers isoliert in der Behälterwand angeordnet wird und die von der Behälterwand isolierte Elektrode bildet. Dadurch wird eine zusätzliche Elektrode für die Leitfähigkeitsmessung mit einer isoliertenThis is achieved according to the invention in that the Metal shell of the temperature sensor insulated in the container wall is arranged and isolated from the container wall Electrode forms. This creates an additional electrode for conductivity measurement with an insulated
Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous further developments of the invention are derived from Subclaims.
In der Fig. ist die Vorrichtung gemäß der Erfindung, teilweise im Schnitt, dargestellt.In the figure the device according to the invention is partially in section, shown.
Die metallische Wand 1, von der in der Fig. nur ein Teil dargestellt ist, bildet z.B. den Behälter einer Geschirrspülmaschine. In einer öffnung der Behälterwand ist das IsolierstoffteiI 3 angeordnet, dessen Kragen 4 sich auf der Innenseite des BehäLters befindet. Durch eine zentra-Ie öffnung des IsolierstoffteiIs 3 ragt das Metallgehäuse des Temperaturfühlers in das Innere des BehäLters. Das Gehäuse 2 enthält irgendeinen geeigneten Temperaturfühler,The metallic wall 1, only a part of which in the figure is shown, for example, forms the container of a dishwasher. This is in an opening in the container wall IsolierstoffteiI 3 arranged, the collar 4 on the inside of the container. Through a zentra-ie The metal housing protrudes from the opening of the insulating part 3 the temperature sensor into the interior of the container. The housing 2 contains any suitable temperature sensor,
