CheeikaJ.ien-Kühlschrank Bit explosions- gescbützteB Innenrsua CheeikaJ.ien refrigerator bit explosion-proof interior

Kühlschränke für den allgemeinen Gebrauch dienen zum Lagern und Kühlen von Lebensmitteln und anderen ungefährlichen Stoffen. Sie werden aber auch zweckentfremdet für die Lagerung von Chemikalien, wie die Praxis zeigt, und dies entspricht in keiner Weise den Richtlinien für die Unfallverhütung.Refrigerators for general use are used to store and cool food and other non-hazardous substances. However, as practice shows, they are also used for the storage of chemicals, and this in no way complies with the guidelines for accident prevention.

Die Erfindung betrifft einen Kühlschrank, der den Anforderungen zum Kühlen und Lagern gefährlicher Stoffe oder brennbarer Flüssigkeiten, die eine explosionsfähige Atmosphäre entwickeln können, entspricht. Dies wird erreicht durch einen eigensicheren Regelkreis mit Temperaturwiderstandsfühler (1) in Verbindung mit einer - in tropfwassergeschutztem Gehäuse an der Rückseite des Kühlschranks befindlichen Regel- und Sicherheitselektronik (3) und dem Sicherheitsfühler (5), der an der Kompressorkapsel (4) fest anmontiert ist. Die Einstellung der Arbeitstemperatur erfolgt über das Bedienungsgerät (6), welches mit einer Digital-Temperatur-Anzeige (LED) für Ist- und Sollwert, einer Prüftaste für eine jederzeit mögliche überprüfung der Sicherheitsfunktion (übertemperaturschutz des Kompressors) sowie mit optischen Anzeigen für Netzbetrieb und Alarmmeldung (bei Aktivierung der Sicherheitsfunktion) ausgestattet ist. Das mit Magnetfolie versehene Bedienungsgerät (6) ist mit der Verbindungsleitung (2) an der Regel- und Sicherheitselektronik (3) fest angeschlossen und kann gut sichtbar an der Vorderseite des Kühlschranks oder in einer speziellen Halterung (7) fixiert {werden.The invention relates to a refrigerator that meets the requirements for cooling and storing dangerous substances or flammable liquids that can develop an explosive atmosphere. This is achieved by an intrinsically safe control circuit with temperature resistance sensor (1) in conjunction with control and safety electronics (3) located in a drip-proof housing on the back of the refrigerator and the safety sensor (5) that is permanently mounted on the compressor capsule (4). The working temperature is set using the control device (6), which is equipped with a digital temperature display (LED) for the actual and setpoint values, a test button for checking the safety function (overtemperature protection of the compressor) at any time, and with optical displays for mains operation and alarm messages (when the safety function is activated). The control device (6) with magnetic foil is firmly connected to the control and safety electronics (3) via the connecting cable (2) and can be fixed in a clearly visible position on the front of the refrigerator or in a special holder (7).

Der Innenraum ist explosionsgeschützt, darüber hinaus sind Bedienungsgerät (6) sowie Regel- und Sicherheitselektronik (3) mit ihren Funktionselementen so ausgestattet, daß eine Funkenbildung auch außerhalb des Kühlschranks ausgeschlossen ist. Auf diese Weise können beim öffnen der Tür eventuell auftretende explosionsfähige Gemische nicht zu einem Schaden führen.The interior is explosion-proof, and the control unit (6) and the control and safety electronics (3) with their functional elements are equipped in such a way that sparks are also excluded outside the refrigerator. In this way, any explosive mixtures that may arise when the door is opened cannot cause damage.
