Definitions
- the invention relates to a refrigerator or freezer according to the preamble of claim 1.
- a pivotable handle is provided as a handle for actuating a door, which when the door is opened via a valve arrangement coupled therewith an airway from the outside into the cooling space enclosed by the device housing and the door releases.
- the valve arrangement is built into the door body and closed when the handle is not actuated.
- a refrigerator or freezer is also known (US Pat. No. 3,201,883) in which a fixed handle with an engagement opening is rigidly attached to a door.
- the door is supported by an elastic seal on a support edge of the housing, the seal being Has hollow chamber profile with an inserted magnetic strip, which is connected to a sealing foot via expansion folds.
- the seal is assigned an automatically acting valve arrangement, which consists of a band that extends from the sealing foot and extends over the hollow chamber profile that receives the magnetic strip and on the opposite side back to the sealing foot. This tape is thus in the sealing joint, so that the seal rests directly on the support edge only in the remaining section.
- the band lying between the magnetic strip and the support edge of the housing weakens the closing force of the seal with respect to the support edge, so that there is already a risk that in normal operation in this area with negative pressure in the cooling space, outside air will flow in and a ripening process will occur.
- the length of the tape must be matched very precisely.
- continuous air channels are formed on the edges of the tape running transversely to the longitudinal direction of the seal, since the tape has a finite thickness and because of its rigidity, the magnetic strip can only press the surrounding sheath against the support edge after a certain distance. Unhindered air exchange takes place particularly through these air channels, which leads to ice and frost layers accumulating in the area in question within the cold room due to the formation of condensation water.
- the invention has for its object in a cooling or Freezer according to the preamble of claim 1 to take measures by which the formation of condensation water in the area of the valve arrangement is avoided in a manually operable valve arrangement serving for pressure equalization without the use of special valve devices.
- a section of the seal which is present anyway for the tight seal, is used as a valve path.
- the handle required for this is preferably assigned to a door handle and is actuated together with the latter when the door is opened.
- the lifting device can be retrofitted to the outside of the door, and the valve does not form any hidden parts, so that good access is possible if icing occurs in this area. If the sealing section is lifted from the support edge of the device housing by the handle, then air can flow freely into the cooling space from the outside and bring about pressure equalization.
- the door opening force is then determined solely by the magnetic strip assigned to the seal, which is usually arranged in the seal and holds the latter in tight contact with the permanent magnetic support edge of the device housing. If the seal has a hollow chamber profile with an expansion fold and is fixed to the door, then the handle only needs to be provided with an actuating tab that engages behind this expansion fold to lift off the sealing section.
- a seal (4) with its inserted magnetic strip (5) rests on a support edge (3) that surrounds a cooling chamber (2).
- the seal (4) is located on a door (6) and has a hollow chamber profile (7) with an expansion fold (8) running in the longitudinal direction of the seal (4).
- the expansion fold (8) runs parallel to the longitudinal direction of the support edge (3).
- the hollow chamber profile (7) between the magnetic strip (5) and the supporting inner surface (9) of the door (6) serves to compensate for tolerances in the gap width between the support edge (3) and the inner surface (9) when the door (6) is closed.
- a fixed handle (10) with an integrally formed foot (11) is attached to the door (6).
- the door (6) is also associated with a handle (13) which has an actuating tab (14) which, with a single-ended bend (15), engages behind the expansion fold (8) on its flank facing the magnetic strip (5).
- the handle (13) is by kinking the seal opposite end of the actuating tab (14) is formed, this handle (13) between the user facing front surface of the door (6) and the actual handle (10).

Description
Die Erfindung betrifft ein Kühl- oder Gefriergerät gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a refrigerator or freezer according to the preamble of
Bei einem bekannten Kühlgerät dieser Art (DE-A-32 05 963) ist als Handhabe zur Betätigung einer Tür ein schwenkbarer Handgriff vorgesehen, der beim öffnen der Tür über eine damit gekuppelte Ventilanordnung einen Luftweg von außen in den vom Gerätegehäuse und der Tür umschlossen Kühlraum freigibt. Die Ventilanordnung ist in den Türkörper eingebaut und bei unbetätigtem Handgriff geschlossen. Dadurch baut sich nach einem dem öffnen folgenden Schließen der Tür durch die Abkühlung der Luft sowie durch die unmittelbar und über ihre gesamte Länge dicht am Auflagerand des Gerätegehäuses aufliegende elastische Dichtung ein Unterdruck im Kühlraum auf, der die Tür über ihre Dichtung mit erheblicher Kraft in der Schließstellung hält. Dieser Unterdruck gleicht sich bei einer Betätigung der Handhabe über die damit gesteuerte Ventilanordnung mit der Außenatmosphäre aus. Abgesehen vom erheblichen baulichen Aufwand für eine in dieser Weise aufgebaute und gesteuerte Ventilanordnung besteht dabei auch die Gefahr, daß sich im Luftweg und an den Ventilflächen Schwitzwasser absetzt, das zu Korrosionen und damit zu Undichtheiten führt und andererseits im Luftweg gefrieren kann und denselben verschließt bzw. die Ventilanordnung blockiert.In a known cooling device of this type (DE-A-32 05 963), a pivotable handle is provided as a handle for actuating a door, which when the door is opened via a valve arrangement coupled therewith an airway from the outside into the cooling space enclosed by the device housing and the door releases. The valve arrangement is built into the door body and closed when the handle is not actuated. As a result, after an opening of the door that follows opening due to the cooling of the air and due to the elastic seal lying directly and over its entire length close to the support edge of the device housing, a negative pressure builds up in the cooling space, which the door with its seal with considerable force in Closed position holds. This negative pressure balances itself with the outside atmosphere when the handle is actuated via the valve arrangement controlled thereby. In addition to the considerable structural outlay for a valve arrangement constructed and controlled in this way, there is also the risk that condensation water settles in the air path and on the valve surfaces, which leads to corrosion and thus to leaks and, on the other hand, can freeze in the air path and close or close it. blocked the valve assembly.
Es ist auch ein Kühl- oder Gefriergerät bekannt (US-A-3 201 883), bei dem auf einer Tür ein feststehender Handgriff mit einer Eingrifföffnung starr befestigt ist. Die Tür stützt sich über eine elastische Dichtung auf einem Auflagerand des Gehäuses auf, wobei die Dichtung ein Hohlkammerprofil mit einem eingesetztem Magnetstreifen aufweist, der über Dehnungsfalten mit einem Dichtungsfuß verbunden ist. Der Dichtung ist eine selbsttätig wirkende Ventilanordnung zugeordnet, die aus einem vom Dichtungsfuß ausgehenden, sich über das den Magnetstreifen aufnehmende Hohlkammerprofil und auf der gegenüberliegenden Seite zurück zum Dichtungsfuß reichenden Band besteht. Dieses Band liegt somit in der Dichtungsfuge, so daß die Dichtung nur im übrigen Abschnitt unmittelbar auf dem Auflagerand aufliegt. Es ist zudem beidendig im Bereich des Dichtungsfußes festgesetzt sowie in der Länge so bemessen, daß bei fehlendem Druckunterschied zwischen der Außenatmosphäre und dem Kühlraum die Dichtung bei geschlossener Tür im Bereich des in der Dichtfuge liegenden Bandes noch zum Auflagerand des Gehäuses hingezogen wird und das Band auf dem Auflagerand aufliegt. Wird die Tür durch Zug an dem starr auf die Tür aufgesetzten Handgriff in Öffnungsrichtung gezogen, dann strecken sich die Dehnungsfalten zwischem dem Dichtungsfuß und dem Magnetstreifen in dem Bereich, in dem das Band nicht vorgesehen ist. Im Bereich des Bandes wird die Dichtung mit der beginnenden öffnungsbewegung von dem zugehörigen Abschnitt des Auflagerandes selbsttätig abgehoben, nachdem das Band eine Streckung der Dehnungsfalten in diesem Bereich nicht zuläßt. Bei diesem Aufbau schwächt das zwischen dem Magnetstreifen und dem Auflagerand des Gehäuses liegende Band die Schließkraft der Dichtung gegenüber dem Auflagerand, so daß bereits dadurch die Gefahr besteht, daß im normalen Betrieb in diesem Bereich bei Unterdruck im Kühlraum Außenluft einströmt und ein Reifansatz eintritt. Zudem muß die Länge des Bandes sehr genau abgestimmt sein. Insbesondere sind jedoch an den quer zur Dichtungslängsrichtung verlaufenden Rändern des Bandes von außen nach innen durchgehende Luftkanäle gebildet, da das Band eine endliche Dicke aufweist und der Magnetstreifen aufgrund seiner Steifigkeit erst nach einer gewissen Strecke die ihn umgebende Hülle an den Auflagerand andrücken kann. Besonders über diese Luftkanäle tritt ein ungehinderter Luftaustausch statt, der dazu führt, daß sich im betreffenden Bereich innerhalb des Kühlraumes infolge der Bildung von Schwitzwasser Eis- und Reifschichten anlagern.A refrigerator or freezer is also known (US Pat. No. 3,201,883) in which a fixed handle with an engagement opening is rigidly attached to a door. The door is supported by an elastic seal on a support edge of the housing, the seal being Has hollow chamber profile with an inserted magnetic strip, which is connected to a sealing foot via expansion folds. The seal is assigned an automatically acting valve arrangement, which consists of a band that extends from the sealing foot and extends over the hollow chamber profile that receives the magnetic strip and on the opposite side back to the sealing foot. This tape is thus in the sealing joint, so that the seal rests directly on the support edge only in the remaining section. It is also fixed at both ends in the area of the sealing foot and dimensioned in length so that when there is no pressure difference between the outside atmosphere and the cooling space, the seal is pulled towards the bearing edge of the housing and the tape is closed when the door is closed in the area of the tape lying in the sealing joint lies on the edge of the support. If the door is pulled in the opening direction by pulling on the handle rigidly placed on the door, the expansion folds stretch between the sealing foot and the magnetic strip in the area in which the band is not provided. In the area of the band, the seal is automatically lifted from the associated section of the supporting edge with the opening movement, after the band does not allow the expansion folds to stretch in this area. With this construction, the band lying between the magnetic strip and the support edge of the housing weakens the closing force of the seal with respect to the support edge, so that there is already a risk that in normal operation in this area with negative pressure in the cooling space, outside air will flow in and a ripening process will occur. In addition, the length of the tape must be matched very precisely. In particular, however, continuous air channels are formed on the edges of the tape running transversely to the longitudinal direction of the seal, since the tape has a finite thickness and because of its rigidity, the magnetic strip can only press the surrounding sheath against the support edge after a certain distance. Unhindered air exchange takes place particularly through these air channels, which leads to ice and frost layers accumulating in the area in question within the cold room due to the formation of condensation water.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Kühl- oder Gefriergerät gemäß dem Oberbegriff des Anspruchs 1 Maßnahmen zu treffen, durch die bei einer dem Druckausgleich dienenden manuell betätigbaren Ventilanordnung ohne die Anwendung besonderer Ventileinrichtungen die Bildung von Schwitzwasser im Bereich der Ventilanordnung vermieden wird.The invention has for its object in a cooling or Freezer according to the preamble of
Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved according to the invention by the characterizing features of
Bei einer Ausgestaltung eines Kühl- oder Gefriergerätes gemäß der Erfindung wird ein Abschnitt der für den dichten Verschluß ohnehin vorhandenen Dichtung als Ventilstrecke ausgenutzt. Hierzu braucht dem betreffenden Abschnitt lediglich eine einfache Aushebevorrichtung zugeordnet zu werden, die manuell zu betätigen ist. Die hierfür erforderliche Handhabe ist vorzugsweise einem Türgriff zugeordnet und wird zusammen mit letzterem beim Öffnungsvorgang der Tür betätigt. Die Abhebevorrichtung kann dabei nachträglich außen an der Tür angeordnet werden, und das Ventil bildet keine verdeckten Teile, so daß ein guter Zugriff möglich ist, falls eine Vereisung in diesem Bereich eintritt. Wird der Dichtungsabschnitt durch die Handhabe vom Auflagerand des Gerätegehäuses abgehoben, dann kann ungehindert Luft von außen in den Kühlraum einströmen und den Druckausgleich herbeiführen. Die Türöffnungskraft ist dann allein durch die der Dichtung zugeordnete Magnetleiste bestimmt, die üblicherweise in der Dichtung angeordnet ist und letztere in dichter Anlage mit dem permanentmagnetischen Auflagerand des Gerätegehäuses hält. Wenn die Dichtung ein Hohlkammerprofil mit einer Dehnungsfalte aufweist sowie an der Tür festgesetzt ist, dann braucht die Handhabe zum Abheben des Dichtungsabschnittes nur mit einer diese Dehnungsfalte hintergreifenden Betätigungslasche versehen zu sein.In one embodiment of a refrigerator or freezer according to the invention, a section of the seal, which is present anyway for the tight seal, is used as a valve path. For this purpose, only a simple lifting device that has to be operated manually needs to be assigned to the section in question. The handle required for this is preferably assigned to a door handle and is actuated together with the latter when the door is opened. The lifting device can be retrofitted to the outside of the door, and the valve does not form any hidden parts, so that good access is possible if icing occurs in this area. If the sealing section is lifted from the support edge of the device housing by the handle, then air can flow freely into the cooling space from the outside and bring about pressure equalization. The door opening force is then determined solely by the magnetic strip assigned to the seal, which is usually arranged in the seal and holds the latter in tight contact with the permanent magnetic support edge of the device housing. If the seal has a hollow chamber profile with an expansion fold and is fixed to the door, then the handle only needs to be provided with an actuating tab that engages behind this expansion fold to lift off the sealing section.

Bei einem nur auschnittsweise dargestellten Gehäuse (1) eines Kühl- oder Gefriergerätes liegt auf einem stirnseitigen, einen Kühlraum (2) umschließenden Auflagerand (3) eine Dichtung (4) mit ihrem eingelegten Magnetstreifen (5) auf. Die Dichtung (4) befindet sich an einer Tür (6) und weist ein Hohlkammerprofil (7) mit einer in Längsrichtung der Dichtung (4) verlaufenden Dehnungsfalte (8) auf. Die Dehnungsfalte (8) verläuft parallel zur Längsrichtung des Auflagerandes (3). Das Hohlkammerprofil (7) zwischen dem Magnetstreifen (5) und der tragenden Innenfläche (9) der Tür (6) dient zum Ausgleich von Toleranzen in der Spaltbreite zwischen dem Auflagerand (3) und der Innenfläche (9) bei geschlossener Tür (6). An der Tür (6) ist ein feststehender Handgriff (10) mit einem angeformten Fuß (11) festgesetzt. Zwischen der Frontseite der Tür (6) und dem Handgriff (10) befindet sich eine Eingrifföffnung (12), in die mit den Fingern einer Hand zum Öffnen der Tür (6) eingegriffen wird:
Der Tür (6) ist auch eine Handhabe (13) zugeordnet, die eine Betätigungslasche (14) aufweist, die mit einer einendigen Abkröpfung (15) die Dehnungsfalte (8) an ihrer dem Magnetstreifen (5) zugewandten Flanke hintergreift. Die Handhabe (13) ist durch Abknicken des der Dichtung abgewandten Endes der Betätigungslasche (14) gebildet, wobei diese Handhabe (13) zwischen der dem Benutzer zugewandten Frontfläche der Tür (6) und dem eigentlichen Handgriff (10) liegt. Die Handhabe (13) ragt somit in die Eingrifföffnung (12). Dabei steht die Handhabe (13) sowohl der Frontfläche der Tür (6) bzw. dem Fuß (11) des Handgriffs und andererseits auch dem Handgriff (10) in unbetätigter Lage mit Abstand gegenüber. Die Betätigungslasche (14) ist zwischen der schmalen äußeren Stirnseite (16) der Tür (6) und einem dieselbe übergreifenden Schenkel (17) des Fußes (11) senkrecht zur Ebene des Auflagerandes (3) bzw. der Frontseite der Tür (6) verstellbar geführt. Die Handhabe (13) kann sich wie dargestellt über einen Teil, aber auch über etwa die volle lichte Höhe der Eingrifföffnung (12) erstrecken.In the case of a housing (1) of a refrigerator or freezer, which is only shown in sections, a seal (4) with its inserted magnetic strip (5) rests on a support edge (3) that surrounds a cooling chamber (2). The seal (4) is located on a door (6) and has a hollow chamber profile (7) with an expansion fold (8) running in the longitudinal direction of the seal (4). The expansion fold (8) runs parallel to the longitudinal direction of the support edge (3). The hollow chamber profile (7) between the magnetic strip (5) and the supporting inner surface (9) of the door (6) serves to compensate for tolerances in the gap width between the support edge (3) and the inner surface (9) when the door (6) is closed. A fixed handle (10) with an integrally formed foot (11) is attached to the door (6). There is an engagement opening (12) between the front of the door (6) and the handle (10), which is inserted with the fingers of one hand to open the door (6):
The door (6) is also associated with a handle (13) which has an actuating tab (14) which, with a single-ended bend (15), engages behind the expansion fold (8) on its flank facing the magnetic strip (5). The handle (13) is by kinking the seal opposite end of the actuating tab (14) is formed, this handle (13) between the user facing front surface of the door (6) and the actual handle (10). The handle (13) thus projects into the engagement opening (12). The handle (13) faces both the front surface of the door (6) or the foot (11) of the handle and on the other hand the handle (10) in a non-actuated position at a distance. The actuating tab (14) can be adjusted between the narrow outer end face (16) of the door (6) and a leg (17) of the foot (11) spanning the same perpendicular to the plane of the support edge (3) or the front of the door (6) guided. The handle (13) can extend as shown over a part, but also about the full clear height of the engagement opening (12).
Wird nach einem Öffnen und anschließendem Schließen die Tür durch den nachfolgend im Kühlraum auftretenden Unterdruck zum Auflagerand (3) hin gezogen, dann kann der durch die Abkühlung der Luft entstehende Unterdruck infolge dicht schließender Dichtung (4) sich nicht mit der Außenatmosphäre ausgleichen. Die Tür (6) liegt dann mit erheblichem Druck auf dem Auflagerand (3) auf und läßt sich nicht oder nur unter entsprechendem Kraftaufwand öffnen, wenn kein Druckausgleich geschaffen wird. Um dies zu erreichen, kann beispielsweise mit einem Finger beim Erfassen des Handgriffs (10) zwischen den Fuß (11) des Handgriffs (10) und die Handhabe (13) eingegriffen werden. Durch die für das Öffnen der Tür erforderliche Zugbewegung wird dann über die Betätigungslasche die Abkröpfung (15) in Anlage mit der Dehnungsfalte (8) der Dichtung (4) gebracht, die beim weiteren Ziehen der Handhabe (13) zum Handgriff (10) hin im unmittelbar benachbarten Abschnitt (18) gemäß Figur (3) unter Zusammendrücken der Hohlkammer (7) abgehoben wird. Im Bereich des Abschnitts (18) kann dann Luft von außen in den Kühlraum (2) einströmen und den Druckausgleich herbeiführen. Dabei wird die Dehnungsfalte (8) nicht stärker als erforderlich zusammengepreßt, weil bei abgehobenem Magnetstreifen (5) die Handhabe (13) gegen die Innenseite des Handgriffs (10) stößt und ein weiteres Zusammenpreßen verhindert, wie es Figur 5 zeigt.If, after opening and then closing, the door is pulled towards the support edge (3) due to the negative pressure that subsequently occurs in the cold room, the negative pressure resulting from the cooling of the air due to the tightly fitting seal (4) cannot balance itself with the outside atmosphere. The door (6) then rests with considerable pressure on the support edge (3) and cannot be opened or can only be opened with the appropriate effort if no pressure equalization is created. To achieve this, for example, a finger can be engaged between the foot (11) of the handle (10) and the handle (13) when gripping the handle (10). Through the pulling movement required for opening the door, the offset (15) is then brought into contact with the expansion fold (8) of the seal (4) via the actuating tab, which in the further pulling of the handle (13) towards the handle (10) immediately adjacent section (18) according to FIG. (3) is lifted while compressing the hollow chamber (7). In the area of the section (18), air can then flow into the cooling chamber (2) from outside and bring about pressure equalization. The expansion fold (8) is not compressed more than necessary because, when the magnetic strip (5) is lifted off, the handle (13) abuts against the inside of the handle (10) and prevents further compression, as shown in FIG. 5.
Daneben ist es auch möglich, mit der Handhabe (13) eine Hebelvorrichtung zu betätigen, die am Gehäuse (1) befestigt sein kann und z. B. über eine in den Auflagerand (3) eingelassene Aushebevorrichtung die Dichtung (4) z. B. mittels eines verschiebbaren Bolzens teilweise vom Auflagerand abdrückt, wenn die Handhabe (13) betätigt wird. Hierzu braucht beispielsweise dem Handgriff nur ein verschiebbarer Knopf zugeordnet werden, der z. B. beim Öffnen der Tür mit dem Daumen gedrückt wird und über ein Gestänge beispielsweise eine im Gehäuse gelagerte Wippe betätigt, die unmittelbar mit einem Arm unter die Dichtung greift oder einen Schieber, Bolzen oder dergleichen zur Dichtung hin verstellt und so die Dichtung vom Auflagerand teilweise abhebt.In addition, it is also possible to operate a lever device with the handle (13), which can be attached to the housing (1) and z. B. on a in the support edge (3) recessed lifting device, the seal (4) z. B. partially by means of a displaceable bolt from the support edge when the handle (13) is actuated. For this purpose, for example, the handle only needs to be assigned a displaceable button which, for. B. is pressed when opening the door with the thumb and operated via a linkage, for example, a rocker mounted in the housing, which engages directly with one arm under the seal or adjusts a slide, bolt or the like to the seal and so the seal from the support edge partially takes off.
