Description
Die vorliegende Erfindung betrifft einen Kühlschrank mit einem Fach für das schnelle Kühlen von Nahrung, insbesondere einen Kühlschrank für den Heimgebrauch.The The present invention relates to a refrigerator with a compartment for fast Cool of food, especially a refrigerator for home use.
Gegenwärtige Kühlschränke für den Heimgebrauch weisen normalerweise wenigstens zwei Fächer mit unterschiedlichen Temperaturen auf, wobei das eine auf einer höheren Temperatur (typischerweise zwischen +3°C und +6°C) für frische Nahrung und das andere auf einer niedrigeren Temperatur (typischerweise –18°C) für gefrorene und tief gefrorene Nahrung ist. Jedes der beiden Fächer ist mit einem jeweiligen Verdampfer versehen, oder mit einem jeweiligen Teil desselben Verdampfers, der ein Teil eines normalen Kühlkreislaufs mit einem Kompressor und einem Kondensator ist.Current refrigerators for home use usually have at least two compartments with different ones Temperatures, the one at a higher temperature (typically between + 3 ° C and + 6 ° C) for fresh food and the other at a lower temperature (typically -18 ° C) for frozen and deep-frozen food is. Each of the two subjects is with provided with a respective evaporator, or with a respective Part of the same evaporator that is part of a normal refrigeration cycle with a compressor and a capacitor.
Diese Kühlschränke sind allgemein "ohne Frost", das heißt mit Einrichtungen ausgestattet, die zum Verhindern der Ausbildung von Frost an der Wand des Verdampfers geeignet sind. Aus diesem Grund ist im Fach mit niedriger Temperatur ein so genannter "ventilierter bzw. belüfteter" Verdampfer vorgesehen, der einer erzwungenen Luftzirkulation unterzogen wird.These Refrigerators are generally "without frost", ie with facilities equipped to prevent the formation of frost on the wall of the evaporator are suitable. For this reason is in the subject with low temperature, a so-called "ventilated" evaporator, which is subjected to a forced air circulation.
Während der Stufe der Nahrungskühlung beginnt jede Nahrung, die zuvor bei einer Temperatur gekocht worden ist, die gleich 90°C oder höher ist, sich aufgrund der schnellen Ausbreitung bzw. Vermehrung der Bakterien, die in der Luft vorhanden sind, und aufgrund der Sporen, die das Kochen überlebten, irreversibel zu verschlechtern. Der Temperaturbereich, innerhalb von welchem die maximale bakterielle Entwicklung stattfindet, liegt zwischen +70°C und +3°C. Je länger der Aufenthalt in dieser Zone ist, um so stärker ist die Änderung des Produkts, und dies passiert dann, wenn eine Nahrung bei Raumtemperatur und/oder in einem normalen Kühlschrank einem Kühlen unterzogen wird. Um dies zu vermeiden, werden Gebläsekühler verwendet, die zulassen, die Temperatur beim Kern der Nahrung in 90 Minuten von +70°C auf +3°C zu bringen. Auf diese Weise ist es möglich, den Prozess eines Alterns des Produkts zu verlangsamen, das für 5/7 Tage im Kühlschrank aufbewahrt werden kann.During the Stage of food cooling Every food that has been cooked at a temperature before begins is equal to 90 ° C or higher is due to the rapid propagation or propagation of the Bacteria that are present in the air and due to the spores, who survived the cooking, to irreversibly worsen. The temperature range, within from which the maximum bacterial development takes place lies between + 70 ° C and + 3 ° C. ever longer the stay in this zone is the stronger the change of the product, and this happens when a food is at room temperature and / or in a normal refrigerator Cool is subjected. To avoid this, blower coolers are used, Allow the temperature at the core of the food in 90 minutes from + 70 ° C + 3 ° C too bring. In this way, it is possible the process of aging of the product, which is kept in the refrigerator for 5/7 days can be.
Auf dieselbe Weise ist es zum Sicherstellen für die Nahrung, die gefroren werden muss, dass die Anfangsqualität während der Gefrierstufe nicht auf irgendeine Weise kompromittiert wird, nötig, dass die letztere schnell stattfindet. In der Tat ändern sich beim schnellen Gefrieren die Nahrungsflüssigkeiten in Mikrokristalle, die die Gewebestruktur des Produkts auf keinerlei Weise beschädigen. Für einen solchen Zweck werden Schnellgefrierer verwendet, die zulassen, die Temperatur im Kern der Nahrung in 240 Minuten von +90°C auf –18°C zu bringen.On the same way it is to ensure food that is frozen must be that the initial quality during the freezing stage is not is somehow compromised, necessary that the latter fast takes place. In fact change during fast freezing the food liquids are in microcrystals, which in no way damage the fabric structure of the product. For one For this purpose, rapid freezers are used, which allow the Temperature in the core of the food in 240 minutes from + 90 ° C to -18 ° C to bring.
Sowohl die Gebläsekühler als auch die Schnellgefrierer sind normalerweise ein Teil eines einzigen Geräts, und dieses Gerät wird auf eine Weise realisiert, die von Haushalts-Kühlschränken getrennt ist.Either the blower coolers as even the quick freezers are usually part of a single one device, and this device is realized in a way that is separate from household refrigerators is.
US-A-5 896 753 offenbart einen Kühlschrank, wie er im Oberbegriff des Anspruchs 1 definiert ist.US-A-5 896 753 discloses a refrigerator, as defined in the preamble of claim 1.
Angesichts des hierin beschriebenen Standes der Technik ist es eine Aufgabe der vorliegenden Erfindung, einen Haushalts-Kühlschrank zu realisieren, der wenigstens ein Fach aufweist, das sowohl als Gebläsekühler als auch als Schnellgefrierer arbeitet.in view of It is an object of the prior art described herein the present invention to realize a household refrigerator, the has at least one compartment, both as a blower cooler and also works as a quick freezer.
Gemäß der vorliegenden Erfindung wird eine solche Aufgabe mittels eines Kühlschranks erreicht, wie er im Anspruch 1 definiert ist.According to the present Invention is such a task by means of a refrigerator achieved as defined in claim 1.
Aufgrund der vorliegenden Erfindung ist es möglich, einen Kühlschrank zu realisieren, der wenigstens ein Fach aufweist, das als Gebläsekühler und als Schnellgefrierer dient und das unabhängig von den anderen Fächern des Kühlschranks arbeitet.by virtue of According to the present invention, it is possible to have a refrigerator to realize that has at least one compartment as a blower cooler and serves as a quick freezer and that regardless of the other subjects of the refrigerator is working.
