Description

Thermostateinrichtung für Kühlschränke Im Hauptpatent ist eine Thermostatvorr ichtung für Kühlschränke beschrieben, bei der das Arbeitsmittel der Vorrichtung, dessen Übergang von flüssiger zu fester Form das Arbeiten des Thermostaten auslöst, beispielsweise aus Wasser besteht. Die vorliegende Erfindung stellt eine Verbesserung des Hauptpatents dar: insofern sie als Arbeitsmittel des Thermostaten Benzol verwendet, das den Vorteil hat, Korrosionen des meist aus Eisen oder Stahl bestehenden Druckkörpers zu verhüten und gleichzeitig, leicht zugänglich und billig zu sein. Da ferner die Kühlschranktemperatur zweckmäßig etwas über dem Gefrierpunkt des Wassers zu halten ist, ist die Verwendung des bei -f- 5° C frierenden Benzols auch aus diesem Grunde günstig.Thermostat device for refrigerators The main patent is a thermostat device description for refrigerators, in which the equipment of the device, whose transition from liquid to solid form triggers the thermostat to work, for example consists of water. The present invention is an improvement of the main patent: insofar as it uses benzene as the working medium of the thermostat, which has the advantage of preventing corrosion of the pressure hull, which is usually made of iron or steel to prevent and at the same time to be easily accessible and cheap. Furthermore, since the It is advisable to keep the refrigerator temperature slightly above the freezing point of the water is, the use of benzene, which freezes at -f- 5 ° C, is also for this reason cheap.

Da sich Benzol beim Gefrieren im Gegensatz zu Wasser zusammenzieht, muß die im Hauptpatent für Wasser beschriebene lhermostatvorrichtung naturgemäß in an sich bekannter Weise entsprechend derart verändert werden, daß das Abstellen der Energiequelle des Apparats erfolgt, wenn der Druck im Thermostaten abnimmt.Since, unlike water, benzene contracts when it freezes, the oil thermostat device described in the main patent for water must naturally be changed in a manner known per se in such a way that the parking the energy source of the apparatus takes place when the pressure in the thermostat decreases.

Als Äquivalente des Benzols kommen ferner in Frage: Cyclohexan, das gleichfalls sehr guten Korrosionsschutz ergibt und bei -f- 6° friert. Ferner Anisaldehyd, Schmelzpunkt -f- 2,5°, Anisidin, Schmelzpunkt +2,5°, Bromnaphthalin (Alpha), Schm°_1zpunkt + 3', o-Dibrombenzol --f- 1,8°, Dimethylanilin + 1,5° und m-Kresol -f- ¢°, deren Schmelztemperaturen gleichfalls den Anforderungen entsprechen.Other possible equivalents of benzene are: Cyclohexane, which also gives very good corrosion protection and freezes at -f- 6 °. Also anisaldehyde, melting point -f- 2.5 °, anisidine, melting point + 2.5 °, bromonaphthalene (alpha), melting point + 3 ', o-dibromobenzene -f- 1.8 °, dimethylaniline + 1.5 ° and m-cresol -f- ¢ °, whose melting temperatures also meet the requirements.
