Description

Die vorliegende Erfindung betrifft ein Kältegerät mit einer Lagerkammer und einer Türöffnungshilfe zum Erleichtern des Öffnens einer Tür der Lagerkammer, die durch einen dem in der Lagerkammer herrschenden Luftdruck ausgesetzten Drucksensor gesteuert ist. Ein solches Kältegerät ist aus DE 10 2006 061 083 A1 bekannt. Die Türöffnungshilfe dieses bekannten Kältegeräts umfasst einen Stellkörper, der, wenn der Drucksensor, verursacht durch einen Benutzer, der an der Tür zieht, einen Unterdruck in der Lagerkammer erfasst, ausgefahren wird, um ein Dichtprofil der Tür von seiner Anlagefläche an einem Rahmen des Korpus fortzudrücken und so einen Druckausgleich zwischen Lagerkammer und Umgebung herbeizuführen.The present invention relates to a refrigerator having a storage chamber and a door opening aid for facilitating the opening of a door of the storage chamber, which is controlled by a pressure sensor exposed to the air pressure prevailing in the storage chamber. Such a refrigeration device is off DE 10 2006 061 083 A1 known. The door opening aid of this known refrigerator comprises a control body which, when the pressure sensor caused by a user pulling on the door detects a negative pressure in the storage chamber, is extended to push a sealing profile of the door away from its abutment surface on a frame of the body and thus to bring about pressure equalization between the storage chamber and the environment.

DE 102 03 425 A1 schlägt ein Kältegerät vor, das mit einem Messgerät zur Erfassung von Druckunterschieden zwischen Innen- und Außenraum des Kältegeräts ausgestattet ist und Mittel zur Herstellung eines Druckausgleichs ansteuert. DE 102 03 425 A1 proposes a refrigeration device equipped with a measuring device for detecting pressure differences between the inside and outside of the refrigerating appliance and controlling means for establishing pressure equalization.

DE 10 2011 084 908 A1 offenbart ein Kältegerät, bei dem ein Temperatursensor in einem Hinterlegteil untergebracht ist, das in einer Öffnung einer Innenverkleidung des Kältegeräts verankert ist. Das Dokument DE10063681 offenbart ein Kältegerät mit einer Türschließ-Erfassungsvorrichtung und mit einem geeigneten Druckdifferenzsensor. DE 10 2011 084 908 A1 discloses a refrigeration device in which a temperature sensor is housed in a backing part which is anchored in an opening of an inner lining of the refrigeration device. The document DE10063681 discloses a refrigerator with a door closer detection device and with a suitable pressure difference sensor.

Aufgabe der vorliegenden Erfindung ist, ein Kältegerät mit Türöffnungshilfe anzugeben, die kostengünstig montierbar ist.Object of the present invention is to provide a refrigerator with door opening help that is inexpensive to install.

Die vorliegende Erfindung ist im unabhängigen Anspruch 1 offenbart. Weitere Ausgestaltungen sind in die abhängigen Ansprüche offenbart.The present invention is disclosed in independent claim 1. Further embodiments are disclosed in the dependent claims.

Unter einem Kältegerät wird insbesondere ein Haushaltskältegerät verstanden, also ein Kältegerät das zur Haushaltsführung in Haushalten oder eventuell auch im Gastronomiebereich eingesetzt wird, und insbesondere dazu dient, Lebensmittel und/oder Getränke in haushaltsüblichen Mengen bei bestimmten Temperaturen zu lagern, wie beispielsweise ein Kühlschrank, ein Gefrierschrank, eine Kühlgefrierkombination oder ein Weinlagerschrank.A refrigeration device is understood in particular to mean a domestic refrigeration appliance, that is to say a refrigeration appliance which is used for household management or possibly also in the gastronomy sector, and serves in particular for storing food and / or drinks in household quantities at specific temperatures, such as, for example, a refrigerator Freezer, a fridge-freezer or a wine storage cabinet.

Vorzugsweise ist der Drucksensor außerhalb einer die Lagerkammer umgebenden Isolationsschicht angeordnet und kommuniziert mit der Lagerkammer über eine sich durch die Isolationsschicht erstreckende Rohrleitung.Preferably, the pressure sensor is arranged outside an insulation layer surrounding the bearing chamber and communicates with the bearing chamber via a pipeline extending through the insulation layer.

Das Hinterlegteil weist vorzugsweise eine flexible Schürze auf, die an einer von der Lagerkammer abgewandten Seite der Wand des Innenbehälters rings um die Öffnung herum anliegt, um einen Durchtritt von Isolationsmaterial durch die Öffnung auszuschließen.The backing member preferably has a flexible skirt which abuts a side of the wall of the inner container remote from the bearing chamber around the opening to preclude passage of insulation material through the opening.

Vorzugsweise hat das Gehäuse zwei Luftdurchlässe, um nicht nur einen Druckausgleich mit der Lagerkammer zu ermöglichen, sondern auch Luftzirkulation zwischen dem Inneren des Gehäuses und der Lagerkammer zu erleichtern.Preferably, the housing has two air passages, not only to allow pressure equalization with the storage chamber, but also to facilitate air circulation between the interior of the housing and the storage chamber.

Dies kommt insbesondere der Genauigkeit des Temperatursensors zugute, der in dem Hinterlegteil untergebracht ist.This is particularly beneficial to the accuracy of the temperature sensor, which is housed in the backing part.

Vorzugsweise ist dieser Rohranschlussstutzen parallel zur Wand des Innenbehälters orientiert, so dass auch das Rohr wenigstens auf einen Teil seiner Länge parallel zur Wand verläuft. Ein Rohr, welches die Isolationsmaterialschicht auf einem zu kurzen Weg kreuzt, ist nicht zweckmäßig, da es als Wärmebrücke zwischen der Lagerkammer und der Umgebung wirken würde.Preferably, this pipe connection piece is oriented parallel to the wall of the inner container, so that the tube extends at least to a part of its length parallel to the wall. A tube crossing the insulation material layer in too short a path is not useful because it would act as a thermal bridge between the bearing chamber and the environment.

Fig. 1 zeigt in einer schematischen perspektivischen Ansicht ein Haushaltskältegerät mit Türöffnungshilfe gemäß der vorliegenden Erfindung. Dargestellt ist ein Kühlschrank in Standbauweise, doch dürfte dem Fachmann anhand der nachfolgenden Beschreibung klar sein, dass die Erfindung auch auf andere Typen von Kältegeräten ohne weiteres übertragbar ist. Fig. 1 shows in a schematic perspective view of a household refrigerator with door opening aid according to the present invention. Shown is a stand-alone refrigerator, but it should be clear to those skilled in the art with reference to the following description that the invention is readily transferable to other types of refrigerators.

Ein wärmeisolierendes Gehäuse des Kühlschranks umfasst einen Korpus 1 und eine daran angelenkte Tür 2, die hier in teiloffener Stellung gezeigt ist, so dass auch eine Lagerkammer 3 im Inneren des Korpus 1 zu sehen ist. Die Tür 2 hat in fachüblicher Weise an ihrer dem Korpus 1 zugewandten Innenseite eine Magnetdichtung 4, die in geschlossener Stellung der Tür 2 an einem sich rings um die Lagerkammer 3 erstreckenden vorderen Rahmen 5 des Korpus 1 dicht anliegt.A heat-insulating housing of the refrigerator comprises a body 1 and a hinged thereto door 2, which is shown here in part-open position, so that a storage chamber 3 can be seen in the interior of the body 1. The door 2 has in a customary manner on its body 1 facing the inside a magnetic seal 4, which rests tightly in the closed position of the door 2 on a ring extending around the bearing chamber 3 front frame 5 of the body 1.

Eine Elektronikplatine 6, auf der sich diverse Schaltungen zum Steuern des Betriebs des Kühlschranks und zum Sichtbarmachen seines Betriebszustandes angeordnet sind, ist hier in einer Aussparung einer die Wände des Korpus 1 ausfüllenden isolierenden Schaumstoffschicht hinter einem Bedien- und Anzeigefeld 7 untergebracht. Bei dem hier gezeigten Standgerät ist das Bedien- und Anzeigefeld 7 in die Vorderkante einer die Oberseite des Korpus 1 bildenden Arbeitsplatte 8 eingefügt, bei anderen Gerätetypen könnte es sich im Rahmen 5 befinden, vorzugsweise in einem Bereich des Rahmens 5, der bei geschlossener Tür 2 nicht von dieser verdeckt ist und somit für einen Benutzer gut erreichbar und sichtbar ist.An electronic circuit board 6, on which various circuits for controlling the operation of the refrigerator and for visualizing its operating state are arranged, is housed here in a recess of the walls of the body 1 filling insulating foam layer behind a control and display panel 7. In the case of the standing device shown here, the control and display panel 7 in the leading edge of a In other types of equipment, it could be located in the frame 5, preferably in a region of the frame 5, which is not covered by this closed door 2 and thus is easily accessible and visible to a user.

An der Elektronikplatine 6, im hier betrachtetem Fall an ihrer Unterseite, ist eine Türöffnungshilfe 9 montiert. Sie umfasst einen elektrischen Aktuator 11 und einen unter der Kontrolle des Aktuators 11 aus einer Öffnung des Rahmens 5 ausfahrbaren Schieber 10. Fig. 1 zeigt diesen Schieber 10 in einer ausgefahrenen, über den Rahmen 5 vorspringenden Stellung, in welcher er, wenn sich die Tür 2 in geschlossener Stellung befände, deren Magnetdichtung 4 lokal vom Rahmen 5 abheben und so einen Druckausgleich zwischen der Lagerkammer 3 und der Umgebung ermöglichen würde.On the electronic board 6, in the case considered here on its underside, a door opening aid 9 is mounted. It comprises an electric actuator 11 and a slide 10 which can be moved out of an opening of the frame 5 under the control of the actuator 11. Fig. 1 shows this slider 10 in an extended, projecting beyond the frame 5 position in which he, if the door 2 would be in the closed position, the magnetic seal 4 locally lift off the frame 5 and so would allow pressure equalization between the storage chamber 3 and the environment ,

Der Aktuator 11 ist gesteuert durch einen Differenzdrucksensor 12, der ebenfalls auf der Elektronikplatine 6 angeordnet ist. Da die Aussparung des Isolationsmaterials, in der die Elektronikplatine 6 untergebracht ist, über diverse Fugen mit der Umgebung kommuniziert, kann einer von zwei Druckanschlüssen des Differenzdrucksensors 12 unmittelbar in die Aussparung einmünden, um den Umgebungsdruck zu erfassen. Ein zweiter Anschluss des Differenzdrucksensors 12 ist über eine sich durch das Isolationsmaterial des Korpus 1 hindurch erstreckende Rohrleitung 13 mit einem Hinterlegteil 14 verbunden, das in einer Seitenwand des Korpus 1 in die Lagerkammer 3 hineinreichend montiert ist.The actuator 11 is controlled by a differential pressure sensor 12, which is also arranged on the electronic board 6. Since the recess of the insulating material in which the electronic board 6 is housed communicates with the environment via various joints, one of two pressure connections of the differential pressure sensor 12 can open directly into the recess in order to detect the ambient pressure. A second connection of the differential pressure sensor 12 is connected via a pipe 13 extending through the insulation material of the body 1 to a backing piece 14, which is mounted in a side wall of the body 1 extending into the bearing chamber 3.

Diese Seitenwand des Korpus 1 umfasst in herkömmlicher Weise einen aus Kunststoff tiefgezogenen Innenbehälter 15, der den Rahmen 5 sowie die Lagerkammer 3 an fünf Seiten begrenzende, im Wesentlichen ebene Wandflächen bildet. In eine dieser Wandflächen 16 ist wie in Fig. 2 gezeigt eine Öffnung 17 geschnitten, in der das Hinterlegteil 14 montiert ist. Das Hinterlegteil umfasst ein inneres Gehäuseteil 18, das durch die Öffnung 17 hindurch in die Lagerkammer 3 hineinragt, ein äußeres Gehäuseteil 19, das auf der der Isolationsschicht 20 aus Schaumstoff zugewandten Seite der Wandfläche 16 angeordnet ist, und eine flexible Schürze 21, die zwischen den miteinander steckverbundenen Gehäuseteilen 18, 19 geklemmt ist und das innere Gehäuseteil 18 sowie gegebenenfalls einen zwischen diesem und dem Rand der Öffnung 17 vorhandenen Spalt von der Isolationsschicht 20 abschirmt, indem sie rings um die Öffnung 17 entlang einer gestrichelten Linie 22 an der Wandfläche 16 anliegt.This side wall of the body 1 conventionally comprises a deep-drawn plastic inner container 15, which forms the frame 5 and the storage chamber 3 on five sides delimiting, substantially flat wall surfaces. In one of these wall surfaces 16 is as in Fig. 2 shown an opening 17 cut, in which the backing part 14 is mounted. The backing part comprises an inner housing part 18 which projects into the storage chamber 3 through the opening 17, an outer housing part 19 which is arranged on the side of the wall surface 16 facing the insulating layer 20 of foam, and a flexible skirt 21 which is arranged between the two clamped together housing parts 18, 19 and the inner housing part 18 and optionally one between this and the edge of the The opening 17 shields the existing gap from the insulating layer 20 by abutting the wall surface 16 around the opening 17 along a dashed line 22.

In zwei horizontalen Wänden 23 des inneren Gehäuseteils 18 sind elastisch auslenkbare Rastvorsprünge 24 zu sehen, die beim Hindurchschieben des inneren Gehäuseteils 18 durch die Öffnung 17 in das Gehäuseteil 18 hinein ausgelenkt werden und nach Passieren der Öffnung 17 elastisch in ihre Ausgangsstellung zurückkehren, um das Hinterlegteil 14 in der Öffnung 17 zu verrasten.In two horizontal walls 23 of the inner housing part 18 elastically deflectable latching projections 24 are seen, which are deflected when pushing through the inner housing part 18 through the opening 17 in the housing part 18 and return to the initial position after passing through the opening 17 elastically to the backing part 14 in the opening 17 to lock.

Zwei Luftdurchlassöffnungen 25 des inneren Gehäuseteils 18 gewährleisten einen freien Luftaustausch mit der Lagerkammer 3, so dass die von einem in dem Hinterlegteil 14 untergebrachten, einen Verdichter des Kühlschranks steuernden Temperaturfühler erfasste Temperatur gut mit der Temperatur im Innern der Lagerkammer 3 übereinstimmt. Eine Halterung 26 für den in der Figur nicht gezeigten, langgestreckt zylindrisch geformten Temperaturfühler ist am äußeren Gehäuseteil 19 gebildet.Two air passage openings 25 of the inner housing part 18 ensure a free exchange of air with the storage chamber 3, so that the temperature detected by a temperature sensor accommodated in the storage part 14, which controls a compressor of the refrigerator, agrees well with the temperature inside the storage chamber 3. A holder 26 for the elongated cylindrically shaped temperature sensor, not shown in the figure, is formed on the outer housing part 19.

Von einer Rückseite des äußeren Gehäuseteils 19 aus erstreckt sich ein Rohr 27 in die Isolationsschicht 20 hinein. Das Rohr 27 beschreibt eine Biegung, so dass ein zum Aufnehmen eines Endes der Rohrleitung 13 aufgeweiteter Rohranschlussstutzen 28 am Ende des Rohrs 27 parallel zur Wandfläche 16 ausgerichtet ist und die darin eingefügte Rohrleitung 13 sich parallel zur Wandfläche 16 bis in Deckenhöhe des Korpus 1 erstreckt.From a rear side of the outer housing part 19, a tube 27 extends into the insulating layer 20. The pipe 27 defines a bend such that a pipe fitting 28 flared to receive one end of the pipe 13 is aligned parallel to the wall surface 16 at the end of the pipe 27 and the pipe 13 inserted therein extends parallel to the wall surface 16 to ceiling height of the body 1.
