Description
Die Erfindung betrifft eine Abdichtvorrichtung für Kühltru hen, Gefriereinrichtungen und Kühlanlagen nach dem Oberbe griff des Anspruchs 1.The invention relates to a sealing device for cooling door hen, freezers and cooling systems after the Oberbe handle of claim 1.
Allgemein ist aus der Druckschrift DE-AS 12 71 127 eine zur Abdichtung eines Kühlinnenraums dienende Dichtung bekannt, die sich durch den Druck beim Verschließen der Kühlschranktür an die abzudichtende Wand anlegt.In general, from DE-AS 12 71 127 is a Sealing of a cooling interior serving gasket known caused by the pressure when closing the refrigerator door against the wall to be sealed.
Ferner ist aus der Druckschrift DE-OS 28 04 971 eine beheiz bare Dichtung bekannt, die aus Silikongummi besteht, dem zur elektrischen Leitfähigkeit Anthrazit beigegeben ist. Es han delt sich hierbei nicht um eine schmelzbare dielektrische Substanz.Furthermore, from DE-OS 28 04 971 a heated bare seal known, which is made of silicone rubber, the for electrical conductivity anthracite is added. It han is not a fusible dielectric Substance.
Der Erfindung liegt die Aufgabe zugrunde, eine Verringerung der Wärmeströme und damit stabile Temperaturverhältnisse im Inneren der Kühltruhe, Gefriereinrichtung oder Kühlanlage zu erzielen.The invention has for its object a reduction the heat flows and thus stable temperature conditions in the Inside the freezer, freezer or cooling system too achieve.
Diese Aufgabe wird bei einer Abdichtvorrichtung nach dem Oberbegriff des Anspruchs 1 durch die Merkmale dieses An spruchs gelöst. Eine Weiterbildung ergibt sich aus dem Un teranspruch.This task is performed in a sealing device according to the Preamble of claim 1 by the features of this type solved. Further training results from the Un claim.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert. In der Zeichnung zeigen:An exemplary embodiment of the invention is described below the drawing explained. The drawing shows:
Fig. 1 einen teilweisen Schnitt durch eine Kühl truhe und Fig. 1 shows a partial section through a freezer and
Fig. 2 eine Dichtung der Abdichtvorrichtung im Schnitt. Fig. 2 shows a seal of the sealing device in section.
Die dargestellte Kühltruhe umfaßt ein Gehäuse 1, einen äuße ren Deckel 2 und einen inneren Verschluß 3 mit zwei profi lierten Platten 4, 5 aus thermoplastischem Stoff, die mitein ander einen Flansch 6 bildend verbunden sind. Das Gehäuse 1 besitzt eine Dichtung 7. Die Dichtung 7 besteht aus einem dünnwandigen flaschenförmig gestalteten Fluoroplast 8. Der flaschenförmige Fluoroplast 8 ist mit einer leicht schmelzba ren dielektrischen Substanz 9 ausgefüllt. Im flaschenförmigen Fluoroplast 8 befindet sich ein elektrisch heizbares Element 10. Auf dem Deckel 2 ist von innen eine Feder 11 mit dem Ver schluß 3 zusammenwirkend befestigt. Die stromleitende Schicht 12 des elektrisch heizbaren Elementes 10 kann aus einem koh lengraphitischen Stoff bestehen.The freezer shown comprises a housing 1 , an outer lid 2 and an inner closure 3 with two profiled plates 4 , 5 made of thermoplastic material, which are joined together to form a flange 6 . The housing 1 has a seal 7 . The seal 7 consists of a thin-walled bottle-shaped fluoroplastic 8 . The bottle-shaped fluoroplastic 8 is filled with a slightly meltable dielectric substance 9 . An electrically heatable element 10 is located in the bottle-shaped fluoroplastic 8 . On the lid 2 , a spring 11 with the circuit 3 is cooperatively attached from the inside. The current-conducting layer 12 of the electrically heatable element 10 can consist of a carbon graphite material.
Die Erfindung arbeitet wie folgt. Bei dem Absperren der Kühl truhe mit dem Verschluß 3 und dem äußeren Deckel 2 schließt man die Stromversorgung des elektrisch heizbaren Elementes 10 für eine notwendige Zeitspanne ein. Diese Zeitspanne ist so bemessen, daß sie für die Schmelze der dielektrischen Sub stanz 9 ausreichend ist. Unterdessen wird auf die Dichtung 7 durch die Kraft einer Feder 11 über den Verschluß 3 ein Druck ausgeübt. Dieser Druck führt dazu, daß die geschmolzene die lektrische Substanz 9 sich immer wieder dem Profil der Stoß stelle zwischen dem Verschluß 3 und dem Gehäuse 1 anpassen kann und so eine zuverlässige Dichtung erreicht. Nach der Schmelze der dielektrischen Substanz 9 wird das elektrisch heizbare Element 10 abgeschaltet. So wird eine Verringerung der Wärmeströme erreicht und damit stabile Temperaturverhält nisse im inneren der Kühltruhe, Gefriereinrichtung oder Kühl anlage erzielt.The invention works as follows. When the freezer is shut off with the closure 3 and the outer cover 2 , the power supply to the electrically heatable element 10 is included for a necessary period of time. This period of time is dimensioned such that it is sufficient for the melt of the dielectric substance 9 . Meanwhile, pressure is exerted on the seal 7 by the force of a spring 11 through the shutter 3 . This pressure leads to the fact that the melted the dielectric substance 9 can repeatedly adjust the profile of the joint between the closure 3 and the housing 1 and thus achieve a reliable seal. After the dielectric substance 9 has melted, the electrically heatable element 10 is switched off. This results in a reduction in the heat flow and thus stable temperature conditions in the interior of the freezer, freezer or cooling system.
