Description
Kältegerät, insbesondere Haushaltsgefrierschrank Refrigerating appliance, in particular household freezer
Die Erfindung betrifft ein Kältegerät, insbesondere einen Haushaltgefrierschrank.The invention relates to a refrigeration device, in particular a household freezer.
Wird die Tür eines Kältegerätes geöffnet, dann gelangt warme Luft in das Innere des Kältegerätes, die sich nach dem Schließen der Tür abkühlt und einen Unterdruck erzeugt, der die Tür gegen die Frontseite des Korpus des Kältegerätes drückt. Der Unterdruck wird zwar mit der Zeit, je nach Kältegerät nach etwa 60 Sekunden, ausgeglichen, hat jedoch zur Folge, dass ein Öffnen der Tür kurz nach dem Schließen der Tür erschwert ist.If the door of a refrigerator is opened, then warm air enters the interior of the refrigerator, which cools after closing the door and generates a negative pressure, which presses the door against the front of the body of the refrigerator. Although the negative pressure over time, depending on the refrigerator after about 60 seconds, balanced, but has the consequence that an opening of the door is made difficult shortly after closing the door.
DE 10 2006 040 381 A1 offenbart ein Kältegerät mit einem Korpus und einer am Korpus angeschlagenen Tür, die einen wärmeisolierten Innenraum begrenzen. Um die Tür jederzeit leicht öffnen zu können, ist in der Wand des Korpus ein Druckausgleichsventil angebracht, das im Falle vom im Innenraum herrschenden Unterdruck Luft von außen nach innen fließen lässt und sperrt, sobald der Druck zwischen Umgebung und Innenraum ausgeglichen ist.DE 10 2006 040 381 A1 discloses a refrigerator with a body and a door hinged to the body, which delimit a heat-insulated interior. In order to be able to open the door easily at any time, a pressure compensation valve is mounted in the wall of the body, which in the case of the negative pressure prevailing in the interior air from outside to inside and locks as soon as the pressure between the environment and the interior is balanced.
Aufgabe der Erfindung ist es, ein vereinfachtes Kältegerät anzugeben, welches Vorraussetzungen schafft, dass dessen Tür jederzeit relativ leicht geöffnet werden kann.The object of the invention is to provide a simplified refrigeration device, which creates conditions that the door can be opened at any time relatively easily.
Die Aufgabe der Erfindung wird gelöst durch ein Kältegerät, insbesondere durch eine Haushaltsgefrierschrank, aufweisend einen Korpus und eine Tür, die bei geschlossener Tür einen wärmeisolierten Innenraum begrenzen, wobei die bei geschlossener Tür in Richtung des Innenraums gerichtete Innenseite der Tür eine Dichtung aufweist, die eingerichtet ist, den Innenraum bei geschlossener Tür zumindest weitestgehend abzudichten, ferner aufweisend wenigstens eine hinter der Dichtung angeordnete Aussparung in der Innenseite der Tür, die eingerichtet ist, Luft unter der Dichtung durchzulassen. Das erfindungsgemäße Kältegerät, bei dem es sich insbesondere um einen Gefrierschrank bzw. um das Gefrierabteil einer Gefrier-Kühlkombination handelt, umfasst demnach die z.B. am Korpus schwenkbar angeordnete Tür, an deren Innenseite, d.h. gegebenenfalls an deren Innentür die Dichtung zum zumindest weitestgehenden Abdichten des Innenraums aufweist. Um ein Öffnen der Tür, die insbesondere kurz vorher geschlossen wurde, so dass im Innenraum ein das Öffnen erschwerender Unterdruck aufgebaut ist, zu erleichtern, ist die Innenseite unterhalb der Dichtung mit der wenigstens einen Aussparung versehen. Die Aussparung ist erfindungsgemäß derart ausgeführt, so dass Luft unter der Dichtung insbesondere bei geschlossener Tür in das Innere des Kältegerätes, d.h. in den Innenraum, strömen kann. Somit stellt die Aussparung eine definierte Undichtigkeit dar, die einen Druckausgleich nach einem z.B. durch ein Öffnen und anschließendes Schließen entstandenen Unterdruck zur Folge hat.The object of the invention is achieved by a refrigeration device, in particular by a household freezer, comprising a body and a door, which define a heat-insulated interior with the door closed, wherein the door is closed in the direction of the interior directed inside of the door has a seal that established is to seal the interior at least as far as possible with the door closed, further comprising at least one arranged behind the seal recess in the inside of the door, which is adapted to let air under the seal. The refrigerator according to the invention, which is in particular a freezer or the freezer compartment of a freezer-refrigeration combination, therefore includes, for example, the door pivotally mounted on the door, on the inside, ie possibly on the inner door, the seal for at least largely sealing the interior having. To open the door, which in particular was closed shortly before, so that in the interior of the opening aggravating vacuum is constructed to facilitate, the inside is provided below the seal with the at least one recess. The recess is inventively designed so that air under the seal, in particular with the door closed in the interior of the refrigerator, ie in the interior, can flow. Thus, the recess is a defined leak, which has a pressure equalization after a resulting example by opening and subsequent closing negative pressure result.
Nach einer Variante des erfindungsgemäßen Kältegeräts weist die Innenseite der Tür eine insbesondere an die Innenseite angezogene Nut auf, mittels der die Dichtung an der Innenseite der Tür befestigt ist.According to a variant of the refrigeration device according to the invention, the inside of the door has a particular tightened on the inside groove, by means of which the seal is fixed to the inside of the door.
Die Dichtung weist dafür z.B. einen Steg auf, der mit der Nut zusammenwirkt, um an der Innenseite der Tür befestigt zu sein. Um sicher zu stellen, dass Luft unter der Dichtung durchströmen kann, ist es gemäß einer Ausführungsform des erfindungsgemäßen Kältegerätes vorgesehen, dass zwischen dem Steg und der Aussparung ein Zwischenraum gebildet ist.The seal has e.g. a web which cooperates with the groove to be attached to the inside of the door. In order to ensure that air can flow under the seal, it is provided according to an embodiment of the refrigeration device according to the invention that between the web and the recess, a gap is formed.
Die Aussparung des erfindungsgemäßen Kältegerätes ist nach einer Ausführungsform insbesondere in der Nut an der Innenseite der Tür einstückig, insbesondere einstoffig mitangeformt, insbesondere mitangezogen. Eine solche Herstellung z.B. mittels Tiefziehens, allgemein mittels Zugdruckumformens ergibt eine Vorrausetzung für ein relativ einfaches und demnach kostengünstiges Herstellungsverfahren für das erfindungsgemäße Kältegerät.The recess of the refrigerator according to the invention is in one embodiment, in particular in the groove on the inside of the door in one piece, in particular mitstoffformt einstoffig, in particular mitangezogent. Such production e.g. By means of deep drawing, generally by means of tension forming, a precondition for a relatively simple and therefore cost-effective production method for the refrigeration device according to the invention results.
Um z.B. eine Gefahr eines Vereisens des erfindungsgemäßen Kältegerätes, insbesondere dessen Verdampfers zu verringern oder gar zu verhindern, ist die Aussparung nach einer bevorzugten Variante in der unteren Hälfte der Tür, insbesondere im untern Drittel der Tür angeordnet.For example, a risk of icing of the refrigerator according to the invention, in particular to reduce or even prevent the evaporator, the recess is arranged according to a preferred variant in the lower half of the door, in particular in the lower third of the door.
Vorzugsweise kann die Dichtung einen im unteren Bereich der Tür insbesondere horizontal verlaufenden Abschnitt umfassen, hinter dem die Aussparung insbesondere mittig bezüglich einer Längsachse der Tür angeordnet ist. Diese Ausführungsform hat sich als besonderes günstig erwiesen, um einem Vereisen des Kältegerätes vorzubeugen. Nach einer Variante des erfindungsgemäßen Kältegerätes ist die Dichtung derart ausgebildet und/oder verläuft derart über der Aussparung, so dass die Dichtung und die Aussparung Spalte bilden, die die Seitenkanten der Dichtung begrenzen. Dadurch ergeben sich Vorraussetzungen, dass die Luft unter der Dichtung von außerhalb des Kältegerätes in den Innenraum strömen kann.Preferably, the seal may comprise a section extending in particular horizontally in the lower region of the door, behind which the recess is arranged in particular centrally with respect to a longitudinal axis of the door. This embodiment has proven to be particularly favorable to prevent icing of the refrigerator. According to a variant of the refrigerator according to the invention, the seal is formed and / or extends over the recess, so that the seal and the recess form gaps which bound the side edges of the seal. This results in conditions that the air can flow under the seal from outside the refrigerator into the interior.
Gemäß einer bevorzugten Ausführungsform des erfindungsgemäßen Kältegerätes ist die räumliche Ausdehnung der Aussparung quer zur Verlaufsrichtung der Dichtung kleiner als die Breite der Dichtung. Somit ist es in relativ einfacher Weise möglich, die beiden durch die Seitenkanten der Dichtung begrenzten Spalte zu realisieren.According to a preferred embodiment of the refrigerator according to the invention, the spatial extent of the recess transverse to the direction of the seal is smaller than the width of the seal. Thus, it is possible in a relatively simple manner to realize the two limited by the side edges of the seal column.
Die Aussparung kann vorzugsweise rechteckförmig ausgebildet sein, wodurch sich die Aussparung relativ einfach herstellen lässt. Die Kantenlängen können bevorzugt zwischen 20mm und 35mm sein. Vorzugsweise sind die Kantenlängen in Verlaufsrichtung der Nut maximal 35mm, vorzugsweise 30mm. Rechtwinklig zur Verlaufsrichtung der Nut sind die Kantenlängen vorzugsweise maximal 30mm, vorzugsweise 26mm.The recess may preferably be formed rectangular, whereby the recess can be relatively easily produced. The edge lengths may preferably be between 20mm and 35mm. Preferably, the edge lengths in the direction of the groove maximum 35mm, preferably 30mm. Right angles to the direction of the groove, the edge lengths are preferably a maximum of 30mm, preferably 26mm.
Die Aussparung kann vorzugsweise mittels Umformen, insbesondere mittels Tiefziehen in die Innenseite der Tür angeformt sein, was eine relativ kostengünstige Herstellung des erfindungsgemäßen Kältegerätes zur Folge haben kann.The recess can preferably be formed by means of forming, in particular by deep drawing into the inside of the door, which can result in a relatively inexpensive production of the refrigerating appliance according to the invention.
Je nach Ausführungsform des erfindungsgemäßen Kältegerätes ist an der Innentür (Innenseite der Tür) insbesondere unten in der Dichtungsnut, bevorzugt in der Mitte der Tür die Aussparung beispielsweise angezogen. Die Luft kann so unter der Dichtung in das Innere des Kältegerätes (Innenraum) strömen, wodurch eine gezielte Undichtigkeit geschaffen wird. Der Querschnitt der Undichtheit durch den Ausschnitt (Aussparung) sollte gegebenenfalls dem aktuelle Kältegerät angepasst werden. Wird beispielsweise die Aussparung zu groß gewählt, kann das erfindungsgemäße Kältegerät ungewollt betauen bzw. vereisen. Die Aussparung sollte auch nicht zu breit gewählt werden, da es dann möglich ist, dass beim Öffnen der Tür die Dichtung aus der Nut gezogen wird.Depending on the embodiment of the refrigeration device according to the invention, the recess is attracted to the inner door (inside of the door), for example, in the lower part of the seal groove, preferably in the middle of the door, for example. The air can flow under the seal in the interior of the refrigerator (interior), creating a targeted leak is created. The cross-section of the leak through the cut-out (recess) should be adapted to the current refrigeration device if necessary. If, for example, the recess is chosen to be too large, the refrigeration device according to the invention can be unintentionally dewed or frozen. The recess should also not be too wide, as it is then possible that when opening the door, the seal is pulled out of the groove.
Das erfindungsgemäße Kältegerät bietet eine kostengünstige Lösung, da beispielsweise das zusätzliche Druckausgleichsventil konventioneller Kältegeräte entfallen kann. Außerdem kann das erfindungsgemäße Kältegerät kostengünstig hergestellt werden, da u.A. die zusätzliche Aussparung nur eine geringe Änderung bestehender Herstellungswerkzeuge erfordert (geringe Umsetzungskosten). Auch ergeben sich Vorraussetzungen für eine saubere Optik. Die erfindungsgemäße Aussparung kann bei relativ vielen Kältegeräten, insbesondere Gefrierschränken verwendet werden. Die Herstellung der erfindungsgemäßen Aussparung in der Innentür ist zusätzlich relativ prozesssicher.The refrigeration device according to the invention offers a cost-effective solution, since, for example, the additional pressure compensation valve conventional refrigerators can be omitted. In addition, the refrigerator according to the invention can be produced inexpensively because the additional recess only requires a small modification of existing production tools (low implementation costs). Also, there are prerequisites for a clean look. The recess according to the invention can be used in a relatively large number of refrigerators, in particular freezers. The production of the recess according to the invention in the inner door is also relatively reliable process.

Figures 3 and 4 show a detailed view of the inner skin 8 in the region of the recess 13 as a plan view and Figures 5 and 6 show a sectional view of a detailed view of the door 6 in the region of the recess 13, the figures 3 and 5, the detail views without and Figures 4 and 6 show the detail view with seal 10. In the case of the present embodiment, the recess 13 was tightened in the groove 11 in the inner skin 8 of the door 6 and is located centrally in the lower part of the door 6, ie in the region of the groove 1 1, in which the portion 10d of the seal 10 is horizontal in the region of the lower horizontally extending outer edge 14 extends.
Im Falle des vorliegenden Ausführungsbeispiels ist die Aussparung 13 rechteckförmig mit einer horizontalen Ausdehnung von 30mm und einer vertikalen Ausdehnung von 26,1 mm. Die Aussparung 13 ist ferner ausreichen tief in die Innenhaut 8 der Tür 6 geformt, so dass der Steg 12 der Dichtung 10 im Bereich der Aussparung 13 nicht die Oberfläche der Innenhaut 8 berührt.In the case of the present embodiment, the recess 13 is rectangular with a horizontal extension of 30mm and a vertical extension of 26.1 mm. The recess 13 is also sufficiently deep formed in the inner skin 8 of the door 6, so that the web 12 of the seal 10 in the region of the recess 13 does not touch the surface of the inner skin 8.
Bei befestigter Dichtung 10 ist die Aussparung 13 hinter der Dichtung 10 angeordnet. Des Weitern ist die Aussparung 13 bzw. die Dichtung 10 derart gewählt, dass bei geschlossener Tür 6 Luft über die Aussparung 13 unter die Dichtung 10 von außerhalb des Gefrierraums 5 in das Innere des Gefrierraums 5 gelangen kann. Dies ist im Falle des vorliegenden Ausführungsbeispiels dadurch realisiert, dass die Dichtung 10 und die Innenhaut 8 im Bereich der Aussparung 13 eine oberen Spalt 16 und einen unteren Spalt 17 bilden, so dass Luft von außerhalb des Gefrierraums 5 über den unteren Spalt 17, dann unterhalb der Dichtung 10 und schließlich über den oberen Spalt 16 in den Gefrierraum 5 gelangen kann, wie dies in der Fig. 6 durch Pfeile 15 veranschaulicht ist.When fastened seal 10, the recess 13 is disposed behind the seal 10. Further, the recess 13 or the seal 10 is selected such that when the door is closed 6 air can pass through the recess 13 under the seal 10 from outside the freezer compartment 5 into the interior of the freezer compartment 5. This is realized in the case of the present embodiment in that the seal 10 and the inner skin 8 in the region of the recess 13 form an upper gap 16 and a lower gap 17, so that air from outside the freezer compartment 5 via the lower gap 17, then below the seal 10 and finally can pass over the upper gap 16 in the freezer compartment 5, as illustrated in FIG. 6 by arrows 15.
In der die Innenhaut 8 der Tür 6 im Bereich der Aussparung 13 mit Dichtung 10 als Draufsicht darstellenden Fig. 4 ist die Dichtung 10 derart dargestellt, dass die Dichtung 10 zumindest im Bereich der Aussparung 13 dünner ist als die vertikale Ausdehnung der Aussparung 13 und die Dichtung 10 im Bereich der Aussparung 13 derart über der Aussparung 13 verläuft, so dass oberhalb der Dichtung 10 im Bereich der Aussparung 13 der obere Spalt 16 und unterhalb der Dichtung 10 im Bereich der Aussparung 13 der unteren Spalt 17 entsteht.In which the inner skin 8 of the door 6 in the region of the recess 13 with seal 10 as a top view illustrative Fig. 4, the seal 10 is shown such that the seal 10 at least in the region of the recess 13 is thinner than the vertical extent of the recess 13 and the Seal 10 in the region of the recess 13 extends over the recess 13, so that above the seal 10 in the region of the recess 13, the upper gap 16 and below the seal 10 in the region of the recess 13 of the lower gap 17 is formed.
In der die Innenhaut 8 der Tür 6 im Bereich der Aussparung 13 mit Dichtung 10 in geschnittener Darstellung darstellenden Fig. 6 ist die Dichtung 10 derart ausgeführt, so dass sie im Bereich der Aussparung 13 zwar die Aussparung 13, wenn von oben betrachtet, teilweise überlappt, jedoch genügend weit von der Oberfläche der Innenhaut 8 entfernt ist, so dass die beiden Spalte 16, 17 entstehen. Der Haushaltsgefrierschrank 1 ist als separater Haushaltsgefrierschrank 1 dargestellt, was jedoch nicht unbedingt nötig ist. So kann der Haushaltsgefrierschrank 1 auch insbesondere Teil einer Kühl-Gefrierkombination sein. In which the inner skin 8 of the door 6 in the region of the recess 13 with seal 10 in a sectional representation representing Fig. 6, the seal 10 is designed such that it in the recess 13 while the recess 13, when viewed from above, partially overlaps , but is far enough away from the surface of the inner skin 8, so that the two gaps 16, 17 arise. The household freezer 1 is shown as a separate household freezer 1, which is not absolutely necessary. Thus, the household freezer 1 may also be part of a refrigerator-freezer in particular.
