Abstract
Description
Die vorliegende Erfindung betrifft ein Kühl- und/oder Gefriergerät mit wenigstens einem im Innenraum des Kühl- und/oder Gefriergerätes befindlichen gesonderten Fach.The present invention relates to a refrigerator and / or freezer with at least one located in the interior of the refrigerator and / or freezer separate compartment.
Herkömmliche Kühl- und/oder Gefriergeräte weisen im Allgemeinen den Nachteil auf, dass innerhalb eines Kühlfaches nur mit großem Aufwand unterschiedliche Temperaturen realisiert werden können. Dies ist jedoch wünschenswert, um den unterschiedlichen Eigenschaften der einzulagernden Güter gerecht zu werden. So weisen beispielsweise Obst und Gemüse andere optimale Lagertemperaturen auf als Wurst und Käse. Ferner ist es bislang nicht möglich, die Luftfeuchtigkeit in einem Teil des Innenraums eines Kühl- und/oder Gefriergerätes zufriedenstellend und abweichend vom übrigen Innenraum des Kühl- und/oder Gefriergerätes einzustellen.Conventional refrigerators and / or freezers generally have the disadvantage that within a refrigeration compartment different temperatures can be realized only with great effort. However, this is desirable in order to cope with the different characteristics of the goods to be stored. For example, fruit and vegetables have different optimal storage temperatures than sausage and cheese. Furthermore, it is not yet possible to adjust the humidity in a part of the interior of a refrigerator and / or freezer satisfactorily and deviating from the rest of the interior of the refrigerator and / or freezer.
Aus dem Stand der Technik sind Kühl- und/oder Gefriergeräte bekannt, die sogenannte Chillerfächer aufweisen, in denen geringere Temperaturen als im eigentlichen Kühlraum vorherrschen. Dabei wird die kalte Luft aus dem Verdampferraum, wobei es sich bei dem Verdampfer um einen Lamellenverdampfer handelt, über Ventilklappen und/oder Luftführungskanäle zu diesem Chillerfach geleitet. Dadurch lassen sich im Chillerfach kältere Temperaturen als im übrigen Kühlraum einstellen. Diese Konstruktion ist jedoch aufwendig und erlaubt nur das Einstellen kältere Temperaturen im Chillerfach.Refrigerators and / or freezers are known from the prior art which have so-called chiller compartments in which lower temperatures prevail than in the actual refrigerator compartment. The cold air from the evaporator room, wherein it is the evaporator is a finned evaporator, passed through valve flaps and / or air ducts to this Chillerfach. As a result, colder temperatures can be set in the chiller compartment than in the remaining cold room. However, this construction is expensive and only allows for setting colder temperatures in the chiller compartment.
Es ist daher die Aufgabe der vorliegenden Erfindung, ein Kühl- und/oder Gefriergerät bereitzustellen, das die aus dem Stand der Technik bekannten Nachteile überwindet und das insbesondere derart gestaltet ist, dass in einem Bereich des Innenraums abweichend vom übrigen Innenraum Temperatur und/oder Luftfeuchtigkeit einstellbar sind.It is therefore an object of the present invention to provide a refrigerator and / or freezer, which overcomes the disadvantages known from the prior art and which in particular is designed such that in a region of the interior deviating from the remaining interior temperature and / or humidity are adjustable.
Diese Aufgabe wird durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 gelöst. Danach ist vorgesehen, dass ein Kühl- und/oder Gefriergerät wenigstens ein im Innenraum des Kühl- und/oder Gefriergerätes befindliches gesondertes Fach aufweist, wobei im Innenraum ein oder mehrere Gebläse vorgesehen sind, wobei das wenigstens eine Gebläse derart angeordnet ist, dass es die Luftführung innerhalb des Kühl- und/oder Gefriergerätes zumindest teilweise durch das Fach und/oder auf das Fach und/oder an dem Fach vorbei führt. Durch diese Art der Luftführung mittels des wenigstens einen Gebläses wird es möglich, das gesonderte Fach gezielt mit einem Kühl- oder Wärmeluftstrom zu beaufschlagen. Somit wird es möglich, auf einfache Weise eine deutlich von der Temperatur des übrigen Kühlraumes abweichende Temperatur in dem gesonderten Fach einzustellen. Die Temperatur kann dabei höher oder niedriger als die Temperatur im Innenraum des Kühl- und/oder Gefriergerätes sein. Das Gebläse kann beispielsweise als Innenraumventilator ausgeführt sein.This object is achieved by a refrigerator and / or freezer with the features of claim 1. Thereafter, it is provided that a refrigerator and / or freezer has at least one separate compartment located in the interior of the refrigerator and / or freezer, wherein one or more fans are provided in the interior, wherein the at least one fan is arranged such that it Air duct within the refrigerator and / or freezer at least partially passes through the compartment and / or on the subject and / or the tray over. By this type of air flow by means of the at least one blower, it is possible to selectively apply the separate compartment with a cooling or heat air flow. Thus, it becomes possible to easily set a temperature significantly different from the temperature of the remaining refrigerator in the separate compartment. The temperature may be higher or lower than the temperature in the interior of the refrigerator and / or freezer. The blower can be designed for example as an indoor fan.
Des weiteren kann vorgesehen sein, dass durch die Anordnung des Gebläses zum Fach die Luftführung innerhalb des Kühl- und/oder Gefriergerätes dergestalt ist, dass die kalte Luft vom Verdampfer kommend in das Fach und von dort in den Innenraum geleitet wird. In dieser Ausführungsform ergibt sich eine einfache Möglichkeit, durch bevorzugte Beaufschlagung des Faches im Fach eine deutlich geringere Temperatur als im übrigen Innenraum des Kühl- und/oder Gefriergerätes einzustellen.Furthermore, it can be provided that the arrangement of the blower to the compartment, the air flow within the refrigerator and / or freezer is such that the cold air coming from the evaporator is passed into the compartment and from there into the interior. In this embodiment, a simple way, by preferential loading of the compartment in the tray results in a much lower Set temperature than the rest of the interior of the refrigerator and / or freezer.
Es ist möglich, dass durch die Anordnung des Gebläses zum Fach die Luftführung innerhalb des Kühl- und/oder Gefriergerätes dergestalt ist, dass die Luft aus dem Innenraum durch das Fach gesaugt wird. In diesem Fall kommt es zu einer deutlich höheren Temperatur im Inneren des Faches verglichen mit dem übrigen Innenraum.It is possible that the arrangement of the fan to the compartment, the air flow within the refrigerator and / or freezer is such that the air is sucked from the interior through the compartment. In this case, there is a much higher temperature inside the compartment compared to the rest of the interior.
Das Fach ist vorzugsweise nicht-isoliert.The tray is preferably non-insulated.
Denkbar ist ferner, dass durch die Anordnung des Gebläses zum Fach die Luftführung innerhalb des Kühl- und/oder Gefriergerätes dergestalt ist, dass die Luft das Fach umströmt, wobei das Fach nicht-isoliert ist. Eine Durchströmung des Faches ist somit nicht zwingend notwendig, da aufgrund der Umströmung z.B. ausreichend Wärme aus dem Fach abgeführt oder auch - je nach Anwendungsfall - weniger Wärme im Vergleich zum Innenraum abgeführt wird. Es kann sich also eine deutlich abweichende Temperatur im Vergleich zur Innentemperatur einstellen.It is also conceivable that the arrangement of the fan to the compartment, the air flow within the refrigerator and / or freezer is such that the air flows around the compartment, the compartment is not-isolated. A flow through the compartment is thus not absolutely necessary, since due to the flow around e.g. sufficient heat is removed from the compartment or - depending on the application - less heat is dissipated compared to the interior. It can therefore set a significantly different temperature compared to the internal temperature.
Außerdem ist es möglich, dass das Fach als geschlossenes Fach ausgeführt ist. Ein derartiges geschlossenes Fach kann frontseitig mittels einer Klappe oder Tür, z.B. aus transparentem Kunststoff verschlossen sein. In ein derartiges Fach kann vorteilhaft Kühlgut eingelagert werden, das bei einer von der Kühltemperatur eines anderen Kühlguts abweichenden Temperatur gelagert werden sollte, um z.B. die maximale Haltbarkeit erreichen zu können.It is also possible that the compartment is designed as a closed compartment. Such a closed compartment can be front-sided by means of a flap or door, e.g. be closed from transparent plastic. In such a compartment can be stored advantageous refrigerated goods, which should be stored at a different temperature from the cooling temperature of another goods to be cooled, for. to reach the maximum durability.
Es kann vorgesehen sein, dass das Fach verschließbare Öffnungen aufweist. Diese Öffnungen können z.B. mittels eines Schiebers verschließbar ausgestaltet sein. Dadurch wird es möglich, im Inneren des Faches eine vom Innenraum abweichende Luftfeuchtigkeit im Fach einzustellen. Durch unterschiedliche Schieberstellungen läßt sich folglich auch die Luftfeuchtigkeit im Fach regeln.It can be provided that the compartment has closable openings. These openings can be made closable, for example, by means of a slider. This makes it possible to set inside the compartment a deviating from the interior humidity in the tray. Due to different slide positions can therefore also regulate the humidity in the subject.
Das Gebläse kann in unmittelbarer Nähe des Faches angeordnet sein. Dadurch kann die Temperatur des Faches unmittelbar beeinflußt werden.The blower can be arranged in the immediate vicinity of the compartment. As a result, the temperature of the compartment can be directly influenced.
Eine weitere Ausführungsform besteht darin, dass das Gebläse (30) entfernt vom Fach angeordnet ist.Another embodiment is that the fan (30) is located away from the compartment.
Es kann vorgesehen sein, dass Mittel zur Luftführung im Innenraum des Kühl- und/oder Gefriergerätes vorgesehen sind. Die Mittel zur Luftführung können dabei Leitbleche und/oder Lüftungskanäle oder -schächte umfassen.It can be provided that means for air guidance in the interior of the refrigerator and / or freezer are provided. The means for air guidance may include baffles and / or ventilation ducts or shafts.
Ebenso ist möglich, dass die Mittel zur Luftführung eine oder mehrere Klappe/n und oder einen oder mehrere Schieber umfassen. Über eine derartige Klappe oder einen derartigen Schieber kann die Kaltluftverteilung und damit auch der Temperaturunterschied zwischen Innenraum und Fach beeinflußt werden.It is also possible that the means for air guidance comprise one or more flap (s) and / or one or more slides. About such a flap or such a slider, the cold air distribution and thus the temperature difference between the interior and the compartment can be influenced.
Von Vorteil ist es, wenn eine Steuerung und/oder Regelung vorgesehen ist, die je nach voreingestellter Temperatur für das Fach die Luftführung durch das Gebläse verändert. So kann je nach z.B. voreingestellter Sollwerttemperatur im Fach der Luftstrom des Gebläses umgekehrt werden, wodurch sich eine zügige und einfache Regelung der Fachtemperatur ergibt.It is advantageous if a control and / or regulation is provided which changes the air flow through the fan depending on the preset temperature for the compartment. Thus, depending on e.g. preset setpoint temperature in the compartment of the air flow of the fan are reversed, resulting in a quick and easy control of the compartment temperature.
Das Fach kann als fest mit dem Innenbehälter des Kühl- und/oder Gefriergerätes montiertes Gehäuse ausgeführt oder aus dem Gerät bzw. Innenbehälter entnehmbar sein. Das Gehäuse kann dabei wahlweise z.B. aus transparentem oder aus eingefärbtem Kunststoff ausgeführt sein.The compartment can be designed as a fixed to the inner container of the refrigerator and / or freezer mounted housing or be removed from the device or inner container. The housing may optionally be e.g. be made of transparent or colored plastic.
Darüber hinaus ist möglich, dass das Fach eine frontseitige Klappe oder Tür aufweist. Bevorzugt wird es, wenn Klappe oder Tür transparent ausgeführt sind. Genausogut kann jedoch die Klappe oder Tür aus eingefärbtem Kunststoff bestehen.In addition, it is possible that the compartment has a front flap or door. It is preferred if flap or door are made transparent. Just as well, however, the flap or door made of colored plastic.
Außerdem ist denkbar, dass das Fach als Auszugsfach ausgeführt ist. Ein derartiges Fach ist insbesondere für die Aufnahme von Obst oder Gemüse gut geeignet.It is also conceivable that the tray is designed as an extract tray. Such a compartment is particularly well suited for the reception of fruit or vegetables.
Das Auszugfach kann dabei wahlweise z.B. aus transparentem oder aus eingefärbtem Kunststoff ausgeführt sein.The pullout compartment may optionally be e.g. be made of transparent or colored plastic.
