Description

B e sc h r e i b u n g über elektrisch betriebenes Abtaugerät für Kühlschränke, Kühltruhen und sonstige Kühleinrichtungen, doppelt isoliert mit drahtlosen Heizleitern Die Erfizidung beinhaltet ein neuartig flüssiges Metallpräparat, welches man passend für die Größe der Vorrichtungen auf ein Grundmaterial aus Kunststoff, Pertinax oder Hartpapier aufdampft, aufdruckt oder durch walzen, pinseln bzw, ätzen in das Grundmaterial hineinbringt, Das Neuartige dabei sind die aufgebrachten Flüssigheizleiter, ferner daß man dasselbe Grundmaterial (isoliertes Material) siehe Figur 1, als Abdeckung hier als Figur 3 benutzt. Die Figur 2 zeigt das aufgebrachte Flüssigmetall. Der große Vorteil der neuen Erfindung besteht darin, daß man nicht wie bei konventionellen Heizdrähten oder Heizspiralen jetzt mit hohen Kosten verbundene Abdeckungen wie isolierte Kästen urw,arbeiten muß, sondern der Heizleiter wird einfach nach seinem Auftragen verklebt, Die Figur 4 zeigt nun die KOntakte und die von diesen Kontakten abaeleiteten Drähte. Die Kontakte mit Ihren Draht sind isoliert durch die Überklebung gemäß Figur 3. Jetzt bringt man die Drähte der Figur 4 aus dem unteren Grundmaterial durch Löcher heraus und vergießt diese unteren Löcher mit flüssigem Kunststoff, Der aufgebrachte elektrische Leiter nebst seiner Anschlußverbindung ist jetzt gemäß den gesetzlichen Vorschriften doppelt isoliert. Die so gemäß Figur 4 herausgebrachten Drähte werden jetzt mit der Stromzuleitung für das Kühlsystem mittels eines Ein- und Aus schalters verbunden, so daß bei Vereisung in einem schnellen Verfahren abgetaut werden kann Die neue Erfindung ist gemäß dieser Beschreibung eine Abtauvorrichtung mit drahtlosen Heizleitern, die sowohl die Heizleiter, die Kontakte und Ableitungsdrähte doppelt isoliert.Description of electrically operated defrosting device for refrigerators, freezers and other cooling devices, double-insulated with wireless heating conductors The invention includes a new type of liquid metal preparation, which is vapor-deposited, or printed on, on a base material made of plastic, Pertinax or hard paper, suitable for the size of the devices by rolling, brushing or etching into the base material. What is new here are the applied liquid heating conductors, furthermore that the same base material (insulated material) see FIG. 1 is used as a cover here as FIG. 3. FIG. 2 shows the applied liquid metal. The great advantage of the new invention is that you do not have to work with high-cost covers such as insulated boxes, as is the case with conventional heating wires or heating coils, but the heating conductor is simply glued after it has been applied the wires deriving from these contacts. The contacts with your wire are insulated by the overlay according to FIG. 3. Now the wires of FIG. 4 are brought out of the lower base material through holes and these lower holes are poured with liquid plastic. The so brought out according to Figure 4 wires are now connected to the power supply for the cooling system by means of an on and off switch, so that in the event of icing can be defrosted in a quick process the heating conductors, contacts and drain wires are double insulated.

Claims

Protection claims

via electrically operated defrosting device for refrigerators, freezers and other cooling devices, double insulated with wireless heating conductors, main claim Insulated wirelessly on plastic, Pertinax or hard paper or another Support applied egg conductor, which with the same or a different insulated Material is shielded or covered and so a new defrosting device that is not exposed to moisture, for refrigerators, freezers and other cooling equipment creates.

2.) UnteraagDruch 1 in connection with the main claim characterized in that that a liquid metal is used as color and thus wirelessly as a heating conductor, which is to be applied to an insulated base material.

3.) Subclaim 2 in connection with the main claim and the subclaim 1 characterized in that the contact is made by gluing or soldering takes place and the cables below or above the insulator base material by two small holes can be made to the connection point. The holes are made with a Insulating fluid encapsulated or connected to the insulator.

4.) Subclaim 3 in conjunction with the main claim and the subclaims 1 - 3 characterized in that the isolator with the applied wireless Heating conductors glued or welded to a second insulator of the same or a different type so that a wetting of the heating conductor or the discharge contacts by moisture is excluded.

5.> Subclaim 4 in conjunction with the main claim and the Sub-claims 1 - 3 characterized in that the gluing of the insulators, be they made of plastic, Pertinax or hard paper or other insulating material can also be done with double-sided adhesive tapes.

6.) Subclaim 5 in conjunction with the main claim and the subclaims 1 - 4 characterized in that if the insulating material is the same on both sides Plastic is used to defrost both down and up or to the left or right side with significant heat output.

7.) Subclaim 6 in connection with the main claim and the subclaims 1 - 5 characterized in that the contacts and their connection with the leads glue. This results in that one is liquid with a special contact precious metal the welding of contacts and cables is achieved.
