Kältegerät mit ButterfachRefrigerating appliance with butter compartment
Die vorliegende Erfindung betrifft ein Kältegerät mit einem gekühlten Innenraum, von dem ein Fach abgeteilt ist, das weniger stark gekühlt ist als der Rest des Innenraumes und dementsprechend meist eine etwas höhere Temperatur aufweist. Ein solches Fach wird allgemein als Butterfach bezeichnet, da es die Möglichkeit bieten soll, Butter streichfähig zu halten, auch wenn der Rest des Innenraumes hierfür zu kalt ist.The present invention relates to a refrigerator with a cooled interior, from which a compartment is divided, which is less cooled than the rest of the interior and therefore usually has a slightly higher temperature. Such a compartment is commonly referred to as a butter compartment, as it should offer the possibility of keeping butter spreadable, even if the rest of the interior is too cold for that.
Eine geeignete Temperatur des Butterfaches war herkömmlicherweise ohne weiteres zu erreichen, indem dieses in einer Ecke des Gehäuses ohne direkten thermischen Kontakt zu einem den Rest des Innenraumes kühlenden Verdampfer platziert war. Verbesserungen bei der Isolation der Kältegeräte führen jedoch dazu, dass die durch eine solche exponierte Platzierung des Butterfaches erreichbare Temperaturdifferenz zum Rest des Innenraums sich verringert, das Butterfach mithin zu kalt wird. Noch geringer wird die Temperaturdifferenz, wenn das Kältegerät nicht in einem beheizten Wohnraum, sondern in einem unbeheizten Raum aufgestellt wird. Das heißt, Bemühungen, Kältegeräte energieeffizient zu bauen bzw. zu betreiben, führen zu dem Problem, dass die Temperatur im Butterfach zu niedrig wird.A suitable temperature of the butter compartment has conventionally been readily achieved by placing it in a corner of the housing without direct thermal contact with an evaporator cooling the remainder of the interior space. Improvements in the insulation of refrigerators, however, lead to the fact that the achievable by such an exposed placement of the butter compartment temperature difference to the rest of the interior is reduced, the butter compartment is therefore too cold. The temperature difference is even lower when the refrigeration device is not installed in a heated living room, but in an unheated room. That is, efforts to build or operate refrigerators in an energy-efficient manner result in the problem that the temperature in the butter compartment becomes too low.
Aufgabe der Erfindung ist, diesem Problem abzuhelfen.The object of the invention is to remedy this problem.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einem Kältegerät mit einem einen gekühlten Innenraum umgebenden wärmeisolierenden Gehäuse, von dessen Innenraum ein Butterfach abgeteilt ist, das Butterfach durch ein Peltierelement temperierbar ist.The object is achieved in that in a refrigerator with a surrounding a cooled interior heat-insulating housing, from the interior of a butter compartment is divided, the butter compartment is temperature controlled by a Peltier element.
Die Heizleistung des Peltierelementes ist zweckmäßigerweise regelbar, um unabhängig von der Umgebungstemperatur, in der das Gerät eingesetzt ist, eine flexible Anpassung an vom Benutzer gewünschte Temperaturen des Butterfaches und des restlichen Innenraumes zu ermöglichen. Im einfachsten Fall kann eine solche Regelung darin bestehen, dass ein Benutzer eine Stromstärke, mit der das Peltierelement beaufschlagt wird, fest vorgeben kann. 200700516The heating power of the Peltier element is suitably regulated to allow a flexible adaptation to user-desired temperatures of the butter compartment and the remaining interior, regardless of the ambient temperature in which the device is used. In the simplest case, such a regulation may consist in that a user can specify a current intensity, with which the Peltier element is acted upon. 200700516
Ein Peltierelement hat herkömmlicherweise eine warme und eine kalte Seite. Von diesen steht vorzugsweise die eine in thermischem Kontakt mit dem Butterfach und die andere in thermischem Kontakt mit einem von dem Butterfach verschiedenen Bereich des Innenraumes. So wird die dem Butterfach zugeführte Wärme im Wesentlichen dem anderen Bereich des Innenraumes entzogen, wodurch eine in herkömmlicher Weise zum Kühlen dieses restlichen Bereiches vorgesehene Kältemaschine entlastet wird.A Peltier element conventionally has a hot and a cold side. Of these, preferably one is in thermal contact with the butter compartment and the other is in thermal contact with a portion of the compartment other than the butter compartment. Thus, the heat supplied to the butter compartment is substantially removed from the other area of the interior space, thereby relieving a refrigerating machine provided in a conventional manner for cooling this remaining area.
Einer besonders bevorzugten Ausgestaltung zufolge ist der von dem Butterfach verschiedene Bereich eine von dem Innenraum abgeteilte Kammer. So ist es möglich, mit Hilfe des Peltierelementes insgesamt drei unterschiedlich temperierte Bereiche zu realisieren, nämlich das Butterfach, die abgeteilte Kammer und einen restlichen Hauptbereich des Innenraumes, wobei die Kammer noch tiefere Temperaturen als der Hauptbereich erreichen kann.According to a particularly preferred embodiment, the area other than the butter compartment is a compartment separated from the interior. Thus, it is possible to realize with the help of the Peltier element a total of three different tempered areas, namely the butter compartment, the partitioned chamber and a remaining main area of the interior, the chamber can reach even lower temperatures than the main area.
Das Peltierelement kann insbesondere im Boden des Butterfachs oder in einer das Butterfach verschließenden Klappe (1 1 ) angeordnet sein.The Peltier element can be arranged in particular in the bottom of the butter compartment or in a flap closing the butter compartment (11).
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Figuren. Es zeigen:Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:
Fig. 1 einen schematischen Teilschnitt durch ein Kältegerät gemäß einer ersten Ausgestaltung der Erfindung; und1 shows a schematic partial section through a refrigerator according to a first embodiment of the invention. and
Fig. 2 einen schematischen Schnitt durch ein Kältegerät gemäß einer zweiten Ausgestaltung der Erfindung.2 shows a schematic section through a refrigeration device according to a second embodiment of the invention.
Fig. 1 zeigt einen vereinfachten Schnitt durch den oberen Bereich eines Kältegerätegehäuses mit einem Korpus 1 und einer Tür 2, die einen Innenraum 3 begrenzen. Von dem Innenraum 3 ist in an sich bekannter Weise in einer oberen vorderen Ecke ein Butterfach 4 abgeteilt. Das Butterfach 4 hat einen von der Tür 2 in den Innenraum 3 hinein vorspringenden Boden 5 und eine eine vertikale Wand und eine horizontale Decke umfassende Klappe 6, deren vertikale Wand auf dem Boden 5 ruht und 200700516Fig. 1 shows a simplified section through the upper portion of a refrigerator housing with a body 1 and a door 2, which define an interior space 3. From the interior 3 a butter compartment 4 is divided in a conventional manner in an upper front corner. The butter compartment 4 has a bottom 5 projecting from the door 2 into the interior 3 and a flap 6 comprising a vertical wall and a horizontal ceiling whose vertical wall rests on the floor 5 and 200700516
deren Decke bei 7 um eine horizontale Achse schwenkbar an die Tür 2 angelenkt ist. Die Klappe 6 verhindert Luftaustausch zwischen dem Inneren des Butterfaches 4 und einem Hauptlagerbereich 14, der den Rest des Innenraumes 3 einnimmt.whose ceiling at 7 about a horizontal axis is pivotally hinged to the door 2. The flap 6 prevents air exchange between the interior of the butter compartment 4 and a main storage area 14, which occupies the rest of the interior space 3.
In den Boden 5 ist ein Peltierelement 8 eingelassen. Das Peltierelement 8 ist mit einem Gleichstrom von durch einen Benutzer an einem nicht dargestellten Regler einstellbarer Stärke beaufschlagt. Die Stromrichtung ist so festgelegt, dass die obere Seite des Peltierelementes 8 warm und die untere kalt ist. Das heißt, das Peltierelement 8 entzieht dem Hauptbereich des Innenraumes 3 Wärme, um sie dem Butterfach 4 zuzuführen.In the bottom 5, a Peltier element 8 is embedded. The Peltier element 8 is acted upon by a direct current from a user to a regulator, not shown, of adjustable intensity. The current direction is set so that the upper side of the Peltier element 8 is warm and the lower one is cold. That is, the Peltier element 8 extracts heat from the main area of the inner space 3 to supply it to the butter compartment 4.
Zweckmäßigerweise ist die Gleichstromquelle an den Betrieb eines (nicht dargestellten) anhand der Temperatur des Innenraumes 3 thermostatgeregelten Verdichters gekoppelt, so dass, wenn ein Benutzer die Thermostatregelung wärmer einstellt und sich dadurch der Anteil der Betriebszeit des Verdichters an der Gesamtbetriebszeit des Kältegerätes verringert, auch die Leistung des Peltierelementes 8 verringert wird und eine übermäßige Erwärmung des Butterfaches 4 durch den Betrieb des Peltierelementes 8 vermieden wird.Conveniently, the DC power source to the operation of (not shown) based on the temperature of the interior space 3 thermostat controlled compressor coupled so that when a user adjusts the thermostat control warmer and thereby reduces the proportion of operating time of the compressor to the total operating time of the refrigerator, the Performance of the Peltier element 8 is reduced and excessive heating of the butter compartment 4 by the operation of the Peltier element 8 is avoided.
Fig. 2 zeigt einen Schnitt durch ein Kältegerät gemäß einer zweiten Ausgestaltung der Erfindung. Auch hier ist ein Butterfach 4 in einer oberen, vorderen Ecke des Innenraumes 3 abgeteilt. Darüber hinaus ist in einem oberen hinteren Bereich eine Verdampferkammer 9 und zwischen dieser und dem Butterfach 4 ein Eisfach 10 abgeteilt. Das Eisfach 10 ist durch eine Klappe 1 1 verschlossen, die bei geschlossener Tür 2 zwischen dem Boden 5 des Butterfaches 4 und einem Boden 12 des Eisfaches 10 gehalten ist. Butterfach 4 und Eisfach 10 können durch Dichtungen 13 zwischen der Klappe 1 1 und dem Boden 5 bzw. 12 weitgehend luftdicht von einem darunter liegenden Hauptlagerbereich 14 abgetrennt sein. Ein in der Klappe 1 1 angeordnetes Peltierelement 8 ist wie oben mit Bezug auf Fig. 1 beschrieben mit Gleichstrom beaufschlagbar, um das Butterfach 4 zu wärmen und das Eisfach 10 zu kühlen.Fig. 2 shows a section through a refrigerator according to a second embodiment of the invention. Again, a butter compartment 4 in an upper, front corner of the interior 3 is divided. In addition, in an upper rear area, an evaporator chamber 9 and between this and the butter compartment 4, an icebox 10 is divided. The freezer compartment 10 is closed by a flap 1 1, which is held with the door closed 2 between the bottom 5 of the butter compartment 4 and a bottom 12 of the freezer compartment 10. Butter compartment 4 and freezer compartment 10 can be separated by seals 13 between the flap 1 1 and the bottom 5 and 12 largely airtight from an underlying main storage area 14. A arranged in the flap 1 1 Peltier element 8 is as described above with reference to FIG. 1 can be acted upon with direct current to heat the butter compartment 4 and to cool the icebox 10.
Da die Klappe 1 1 hier die Doppelfunktion hat, sowohl das Eisfach 10 als auch das Butterfach 4 von dem Hauptlagerbereich 14 zu trennen, entfällt die an der Tür befestigte Klappe 6 der Ausgestaltung von Fig. 1 , und es kann bei geöffneter Tür 2 auf den Inhalt des Butterfaches 4 frei zugegriffen werden, ohne eine weitere Klappe öffnen zu müssen. Since the flap 1 1 here has the dual function of separating both the freezer compartment 10 and the butter compartment 4 from the main storage area 14, eliminates attached to the door flap 6 of the embodiment of Fig. 1, and it can with the door open on the 2 Contents of the butter compartment 4 are freely accessed without having to open another flap.
