Description
Es sind bereits elektrische Erhitzer bekannt, bei denen durch den Auftrieb des Wassers bzw. durch die Energie des strömenden Mediums eine Kontaktvorrichtung ge- t steuert wird. Im vorliegenden Falle handelt es sich um eine von der Heizvorrichtung1 völlig getrennte Kontaktvorrichtung, welche mit jedem beliebigen Apparat in Reihe geschaltet werden kann, zum Zwecke, das Durchbrennen dieser Heizkörper zu verhüten.There are already known electric heater, in which a contact device is overall controlled by the t buoyancy of water or by the energy of the flowing medium. In the present case, it is a completely separate contact device from the heating device 1 , which can be connected in series with any desired apparatus, for the purpose of preventing these heating elements from burning through.
Gegenstand der Erfindung ist eine Ein- und Ausschaltvorrichtung für elektrisch beheizte Apparate, welche vornehmlich zum Kochen von Flüssigkeiten und Erwärmen von durchströmender Luft verwendet werden. Der Zweck der Erfindung ist der, den elektrischen Heizkörper beim Auskochen, der Flüssigkeit oder Abstellen der durchströmenden Luft auszuschalten und die Stromzuführung erst wieso der zu bewirken, sobald normale Betriebsverhältnisse hergestellt sind, so daß das durch Fahrlässigkeit usw. verschuldete üble Durchbrennen der elektrischen Heizung vermieden wird. Die den Apparat zum Ein- oder Ausschalten des Stromes bringenden Kräfte sind die den Apparat umgebende Luft oder Flüssigkeit selbst. Das Schließen und Unterj brechen der Stromzuführung erfolgt durch J Andrücken oder Abziehen eines Stromleiters an oder von der stromführenden Leitung. j Der Apparat wird in dem Luftrohr oder j der zu kochenden Flüssigkeit befestigt und mit dem Heizkörper durch Leitungsdrähte in üblicher Weise verbunden.The invention relates to an on and off switch for electrically heated Apparatus used primarily for boiling liquids and heating liquids flowing through them Air can be used. The purpose of the invention is the electrical Switch off heating elements when boiling the liquid or switching off the air flowing through and the power supply only why the cause as soon as normal operating conditions are established, so that through Negligence, etc., avoided bad burnout of the electric heater will. The forces that bring the apparatus to switch the current on or off are the air or liquid surrounding the apparatus itself. The closing and subj The power supply is broken by pressing on or pulling off a conductor to or from the live line. j The device is attached to the air tube or j the liquid to be boiled and connected to the radiator by lead wires in the usual way.
Der Gegenstand der Erfindung ist in den Abb. ι und 2 im Grundriß und Aufriß in zwei Ausführungsarten dargestellt.The object of the invention is in Figs. Ι and 2 in plan and elevation in two types of execution shown.
Der Schwimmer α (Abb. 1) hat in seinem Innern ein trichterförmiges Metallprofil, das an zwei ebenfalls trichterförmig· geformte,, vonein-"The inside of the float α (Fig. 1) has a funnel-shaped metal profile, which is attached to two also funnel-shaped "from one-"
ander durch d isolierte Metallteile b, b paßt. Die beiden Drähte e, e sind mit den Teilen b, b leitend verbunden und voneinander durch Isolationsmaterial h getrennt. Ist nun Wasser in dem Gefäß, so wird der Schwimmer an die Metallteile b, b gedrückt. Der Stromkreis ist also jetzt, sofern die Anlage eingeschaltet und in Ordnung ist, geschlossen. Ist das Wasser so weit verdampft,other metal parts b, b insulated by d fit. The two wires e, e are conductively connected to parts b, b and separated from one another by insulating material h . If there is now water in the vessel, the float is pressed against the metal parts b, b. The circuit is now closed, provided the system is switched on and in order. Has the water evaporated so far
ίο daß es. den Schwimmer nicht mehr trägt, werden die Kontaktstellen α und b getrennt und dadurch der Strom unterbrochen. Durch entsprechendes Einbauen des Schwimmers ist es möglich, den Strom in der gewünschten Wasserhöhe zu unterbrechen. Ein Herabfallen des Schwimmers verhütet der Stifte und die Mutter /.ίο that it. no longer carries the float, the contact points α and b are separated and the current is thereby interrupted. By installing the float accordingly, it is possible to interrupt the current at the desired water level. The pins and the nut / prevent the float from falling.
Nach demselben Prinzip arbeitet der Apparat zum Abstellen der Heizung für durchströmende Luft (Abb. 2), nur ist an demselben an Stelle des Schwimmers eine Art Teller angebracht, den die durch das Rohr oder den Heizkörper strömende Luft an die Kontaktstellen b, b drückt. Um bei von oben nach unten strömender Luft ein immerwährendes Auffliegen des Trichters auf die Kontaktstellen b, b zu verhüten, ist um den Stift c eine Feder g gelegt, die so bemessen ist, daß sie eben gerade das Gewicht des Tellers mit Trichter trägt. Das Aufhören der Luftzuführung bewirkt das Unterbrechen des elektrischen. Stromes.The device for switching off the heating for air flowing through works according to the same principle (Fig. 2), only instead of the float a kind of plate is attached to it, which the air flowing through the pipe or the radiator presses to the contact points b, b. In order to prevent the funnel from constantly flying up onto the contact points b, b when the air flows from top to bottom, a spring g is placed around the pin c , which is dimensioned so that it just bears the weight of the plate with the funnel. Stopping the air supply causes the electrical to be interrupted. Current.
