Definitions
- the present invention relates to a refrigerating appliance comprising a heat-insulating housing, the interior of which is accessible via an openable and closing door, at least one flow path for supplying air into the interior space, a fan for generating an air flow along the flow path, and an air filter which is in the Flow path is arranged, wherein the air filter is integrated in one of the positive pressure side of the blower upstream protective cover.
- a refrigerator is eg from the US-A1-2005 / 0022549 known. From the DE 23 44 261 A1 is a refrigerator known for household purposes. It describes a filter system with which can be eliminated in the refrigerated goods storage room odors.
- the refrigerator is provided with an internal air circulation system with fan arranged therein and filter device.
- the fan is located in a lower rear portion of the refrigerator in insulation.
- the filter device is arranged in the interior of the refrigerator and that in a lower region on one of the two refrigerator side walls and consists of a housing in which a filter insert is arranged easily replaceable.
- the housing is provided with a lid which, in the closed state, effects a tight contact between the filter insert and the housing seal.
- the filter device is located in a vacuum-side suction line of the circulating air system and detects the flow cross-section of the suction line completely.
- a fluidically similar solution is in DE 75 16 271 U1 shown.
- a device for producing purified cooling air for pharmacy cabinets is described.
- the device consists of a box-like housing, one wall of which is formed of a fine-mesh grid.
- the filter mats are arranged in the interior of the housing, behind the grid different filter mats are arranged.
- the interior is divided by an inner wall, on which a fan is arranged.
- a pressure chamber is provided between the inner wall, an outer wall and parts of the remaining walls.
- the filter mats are arranged in a vacuum-side suction line of the cooling system and detect the flow cross-section of the suction line completely.
- the air cleaner includes a housing having at least an inlet and an outlet, a linear reciprocating decorative plate for selectively opening or closing the outlet, a filter unit for filtering air sucked through the inlet, a fan for drawing in air over the inlet Inlet and for discharging the filtered air in the filter unit via the outlet.
- the filter unit for filtering air sucked in via the inlet is located in a vacuum-side suction line of the air-cleaning device and detects the flow cross section of the suction line completely.
- the air cleaning device is functionally independent of the refrigerator and placed separately on the top.
- a refrigerator in which an air filter is arranged in a pressure-side portion of a flow path is in JP 2005090910 A shown.
- the disinfection filter described therein is arranged downstream of a fan, is thus located in a pressure-side portion of a flow path.
- the disinfection filter is located in a flow channel of a separate secondary fan.
- the disinfection filter and the secondary fan are in turn in a vacuum-side suction line of a primary fan, which generates the actual air flow into the interior of the housing of the refrigerator. Consequently, the secondary fan does not serve to generate an air flow for supplying air into an interior of the refrigerator, but merely as an auxiliary fan for overcoming a pressure drop across the disinfection filter. Since the disinfection filter extends completely over its flow channel, in order to achieve a filtering effect, the air flow must necessarily be conveyed completely through the disinfection filter.
- the US 5,400,612 describes a coolable and humidable storage cabinet in which a structure for attractively collecting moisture is arranged in a flow channel, which extends over only a part of the flow cross-section.
- the JP 2002 277152 A describes a refrigerator with a flow channel in which a filter is arranged, which extends only over part of the flow cross-section.
- the object of the invention is to provide an air filter for a refrigerator, which has a sufficient filtering effect with little obstruction of the air flow in the refrigerator.
- the object is achieved by a refrigeration device with the features of claim 1.
- the air filter In order to pressurize the air filter with at least a part of the air to be circulated, the air filter can be positioned in the air stream without hindering it too much.
- the air filter extends in the flow path only over part of its flow cross-section, a part of the air flowing through the flow path is passed through the air filter and the remaining part flows around the air filter without being filtered by it.
- the proportion of air flowing past the air filter ensures a slight obstruction of the air flow in the refrigeration device.
- the passing through the air filter portion of the air ensures a sufficient filtering effect. It has been found that it is quite sufficient to lead only a portion of the air to be circulated through the air filter.
- the invention relates in this respect a way to save electrical energy, on the one hand, no additional second blower is necessary and on the other hand, the necessary existing first blower can be operated under the lowest possible pressure drop, whereby the consumption of electrical energy of this first blower can be reduced.
- the blower according to the invention can be any type of air flow generator.
- the fan for ventilating the interior of the refrigerator may be a fan.
- the fan generally has a fast-rotating impeller, the blades of which bring the air by their rotary motion in motion.
- the fan of the fan is rotationally driven by an electric motor.
- the air filter extending in the flow path only over part of its flow cross section can extend over the center of the flow cross section. To ensure a good flow through the air filter, this can be placed directly in front of the fan in the pressure range. This has the advantage that the air filter is at least predominantly in an area in which the highest flow velocities occur. If the air filter is arranged in this area with the highest flow velocities, then, based on the cross-sectional portion occupied by the air filter from the entire flow cross-section, a higher air volume throughput can be conveyed through the air filter. Thus, a predominant volume fraction of the air is passed through the air filter and only a smaller volume fraction of the air can flow past the air filter. This takes into account the divergent goals, on the one hand to clean a maximum proportion of air through the air filter and on the other hand to achieve a minimal pressure drop through a free unhindered cross section as possible.
- the air filter can preferably be arranged in the center of the flow cross-section in the flow path.
- the flow lines with the highest speeds in cross-sectional areas are to be expected, which are as far away from the walls of the flow channel, so preferably lie in a center of the respective flow channel.
- the center of the flow path is to be found where, depending on the cross-sectional contour, the flow lines with the highest speeds occur.
- This fluidic property is dependent not only on the respective contour of the flow cross section but also on the internal surface texture, in particular on the adhesion of the air flow to the surface.
- the center of the highest air velocities can also be outside the geometric center of the circular cross section. This is also the case when the air filter is in a pipe bend.
- the air filter is arranged in a pressure-side section of the flow path.
- This has the advantage that, compared to an arrangement of the air filter in a vacuum-side portion of the flow path of the air filter is subjected to higher pressure, whereby air filter with a high flow resistance still sufficient air can be flowed through.
- a fine-pored air filter which can be configured as activated carbon filter with catalytic effect, a relatively higher flow resistance than in a conventional coarsely porous dust filter with a simple filter fleece.
- the air filter is upstream of a positive pressure side of the blower. This causes the air flow can enter the air filter immediately or at least shortly after leaving the fan. This has the advantage that the air flow is entered at maximum speed and energy in the air filter. If the air filter were to be arranged very far away from the blower, the air flow would have already significantly lost flow velocity or energy, for example due to the wall friction in the flow channel, so that the air could only be reduced to a lesser extent by the lesser energy Air filter could be passed through. The arrangement of the air filter immediately or at least shortly after leaving the blower thus leads to a high flow of pleasure flow through the air filter. Conversely, this means based on the same air filter performance a lower demand for electrical energy for the drive motor of the fan.
- the air filter is also integrated in one of the positive pressure side of the blower upstream protective cover.
- a separate holder may be provided, on the one hand carries the air filter and on the other hand is fixed to an inner wall of a flow channel.
- a preferably electric motor-operated fan will be installed immediately just behind an inner wall of the housing bounding the interior.
- the exhaust opening of the fan or blower is generally provided with a protective cover.
- the protective cover is designed such that the largest possible cross-section remains open for an unimpeded passage of the air flow.
- the protective cover is designed such that an intervention of a person, for example, with the fingers of one hand is reliably prevented.
- the opening or the openings of the air flow must be made correspondingly narrow.
- the protective cover is formed as a grid, which may be made of plastic, for example.
- a safety cover which is already required for safety reasons is used functionally as a holder for the air filter. This has the advantage that a separate holder can be omitted and thus the production costs are reduced.
- the protective cover for interchangeable holding the air filter has a receptacle for the air filter.
- the air filter is therefore kept interchangeable.
- the protective cover is not designed plan, but provided for example with a trough-like receptacle.
- This recording can be integrally formed with the protective cover.
- the receptacle can dip so far into the protective cover that the air filter, which in particular can be designed as a filter tablet, is completely absorbed. After the air filter is fully inserted into the receiving table, the remaining hatch opening can be closed by means of an openable and closable lid, so that the air filter is held and can not fall out of the protective cover.
- the receiving recess of the protective cover has an open side closable by the cover, which points into the interior of the refrigeration device.
- the closable open side forms according to a through-opening over which a spent air filter removed from the protective cover and a new air filter can be used.
- the replacement of the air filter can be carried out automatically by a user, the open side into the interior of the refrigerator, so that the user with the door open of the refrigerator from the interior can open the lid and remove the air filter from the recording.
- the air filter is in this respect for a user to remove or replace through an opening accessible in the interior. To ensure the necessary electrical safety, the fan cover is not removable even for the user.
- the refrigeration device can also be operated safely without inserted air filter, ie the niche formed like a trough for receiving the air filter is blocked in a lattice-like manner with respect to the fan, so that even when the air filter is removed an intervention in the area of the fan is reliably prevented.
- the air filter is easily replaceable, as it is very quick and easy to recognize when the user has opened the door of the refrigerator. In addition, it is very easily recognizable to the user, whether an air filter is used, so that the air-cleaning effect for the user in the interior of the refrigerator is visualized.
- the air filter is designed as a filter tablet, which is designed for insertion into the receptacle of the protective cover.
- the air filter is preferably as formed an activated carbon filter with catalytic effect. Due to the design of the air filter as a filter tablet, the air filter is directly in the air flow and can thus develop its odor-reducing potential or its air-cleaning effect.
- the filter tablet may for this purpose have a size that extends in its mounted on the protective cover of the blower position only over part of the flow cross-section of the protective cover.
- the filter tablet may have such a handy size, so that the filter tablet can be used with two fingers of one hand in the receiving tables in the interior of the refrigerator.
- the filter tablet may be formed as a cuboid tablet. This basic form is already known, for example, in dishwasher detergent tablets. Due to the special design of the air filter as a filter tablet, the user can be stimulated to a similar to the cleaning tablet for dishwashers handling. As a result, the user is reminded to replace the air filter regularly and therefore in good time before the air purifying effect wears off.
- a refrigerator 1 according to Fig. 1 has a heat-insulating housing 2.
- the housing 2 comprises a trough-shaped inner container 3, two opposite lateral decorative walls 4a and 4b, and a ceiling wall 5, a rear wall 6 and a bottom wall 7. Between the decorative walls 4a and 4b, the ceiling wall 5, the rear wall 6, the bottom wall 7 and the inner container 3, a gap is formed which is filled to achieve a heat-insulating effect with thermal insulation material, in particular foamed with a heat-insulating foam.
- the front open inner container 3 defines an interior space 8, which is heat-sealed by means of a pivotally mounted on hinges 9 on the housing 2 door 10.
- a flow channel 11 for air which defines a flow path A, B, C, D, is conveyed along the air by means of a blower 13 arranged in the flow path A, B, C, D.

- the fan shaft 15 is rotationally driven by means of an electrically driven motor 16.
- the blades 16 are set in motion and convey air from the flow channel 11 (arrow A) in the interior 8 into it (arrow B).
- the air sucked in from the flow channel 11 by the blower 13 can be air drawn in from the surroundings or, as illustrated by arrow D, circulating air from the interior 8, as illustrated by arrow C.
- the fan 13 is a protective cover 17 downstream in the flow direction, ie the protective cover 17 shields the fan 13 from the interior 8 from.
- a partial surface of the protective cover 17 is formed as a discharge grille 18.
- the protective cover 17 has a central portion 19 which is provided with a plurality of exhaust openings 20.
- the exhaust openings 20 are bounded by webs 21.
- the webs 21 are formed as straight ribs, which frame rectangular outlet openings 20.
- the webs 21 so far form the outlet grille 18.
- the protective cover 17 has in addition to this central portion 19 also has two lateral sections.
- the lateral portions are formed on opposite sides of the central portion 19 in a mirror-symmetrical arrangement on the protective cover 17.
- a side portion 22 is in Fig. 2 shown.
- the lateral portion 22 is formed without flow openings. Only the outlet grille 18 defines an overpressure-side flow cross-section 23.
- the outlet grille 18 is the blower 13 immediately upstream. To improve a uniform distribution of air in the interior 8 of the central portion 19 and the outlet grille 18 is curved, so that air flowing through the outlet grille 18, in a wide fan in the interior 8 can escape.
- a receptacle 24 is provided in the center of the outlet grille 18.
- the recording 24 forms one of the in the Interior facing surface of the outlet grille 18 in the direction of the fan 13 recessed niche.

Die Aufgabe wird durch ein Kältegerät mit den Merkmalen des Anspruchs 1 gelöst.The object of the invention is to provide an air filter for a refrigerator, which has a sufficient filtering effect with little obstruction of the air flow in the refrigerator.
The object is achieved by a refrigeration device with the features of
Um den Luftfilter zumindest mit einem Teil der umzuwälzenden Luft zu beaufschlagen, kann der Luftfilter im Luftstrom positioniert werden, ohne diesen zu stark zu behindern. Indem der Luftfilter sich im Strömungsweg nur über einen Teil dessen Strömungsquerschnitts erstreckt, wird ein Teil der den Strömungsweg durchströmenden Luft durch den Luftfilter geführt und der übrige Teil umströmt den Luftfilter, ohne von diesem gefiltert zu werden. Der am Luftfilter vorbeiströmende Anteil der Luft gewährleistet eine geringe Behinderung der Luftströmung im Kältegerät. Andererseits gewährleistet der durch den Luftfilter hindurchtretende Anteil der Luft eine ausreichende Filterwirkung. Es hat sich gezeigt, dass es durchaus ausreichend ist, nur einen Teil der umzuwälzenden Luft durch den Luftfilter zu führen. Aufgrund eines mehrfachen Umwälzens der Luft findet ein Austausch von gefilterter Luft mit ungefilterter Luft statt, so dass insgesamt die Luft nach einer eintretenden Durchmischung gegenüber dem Ursprungszustand ausreichend gereinigt ist. Der am Luftfilter vorbeiströmende Anteil der Luft verhindert einen zu großen Druckabfall im Luftsystem, so dass ein ausreichend hoher Luftaustausch stattfinden kann. Ein gesonderter Lüfter oder Gebläse zur Druckerhöhung vor dem Luftfilter ist dabei entbehrlich. Aufgrund der speziell bei Kühlgeräten hohen Anforderungen an die Energieeffizienz, ist es sinnvoll auf jeden Verbrauch von elektrischer Energie zu achten. Die Erfindung betrifft diesbezüglich eine Möglichkeit, elektrische Energie dadurch einzusparen, dass einerseits kein zusätzliches zweite Gebläse notwendig wird und andererseits das notwendiger Weise vorhandene erste Gebläse unter möglichst geringen Druckabfall betrieben werden kann, wodurch der Verbrauch an elektrischer Energie dieses ersten Gebläses verringert werden kann.In order to pressurize the air filter with at least a part of the air to be circulated, the air filter can be positioned in the air stream without hindering it too much. By the air filter extends in the flow path only over part of its flow cross-section, a part of the air flowing through the flow path is passed through the air filter and the remaining part flows around the air filter without being filtered by it. The proportion of air flowing past the air filter ensures a slight obstruction of the air flow in the refrigeration device. On the other hand, the passing through the air filter portion of the air ensures a sufficient filtering effect. It has been found that it is quite sufficient to lead only a portion of the air to be circulated through the air filter. Due to a multiple circulation of the air, an exchange of filtered air with unfiltered air takes place, so that overall the air is sufficiently cleaned after an incoming mixing with respect to the original state. The proportion of air flowing past the air filter prevents an excessive pressure drop in the air system, so that a sufficiently high exchange of air can take place. A separate fan or blower to increase the pressure in front of the air filter is dispensable. Due to the high demands on energy efficiency, especially for refrigerators, it makes sense to pay attention to every consumption of electrical energy. The invention relates in this respect a way to save electrical energy, on the one hand, no additional second blower is necessary and on the other hand, the necessary existing first blower can be operated under the lowest possible pressure drop, whereby the consumption of electrical energy of this first blower can be reduced.
Das erfindungsgemäße Gebläse kann jede Art von Luftstromerzeuger sein. Insbesondere kann das Gebläse zur Lüftung des Innenraums des Kältegerätes ein Ventilator sein. Der Ventilator weist im allgemeinen ein sich schnell drehendes Lüfterrad auf, dessen Schaufeln die Luft durch ihre Drehbewegung in Bewegung bringen. Üblicher Weise ist das Lüfterrad des Ventilators von einem elektrischen Motor drehangetrieben.The blower according to the invention can be any type of air flow generator. In particular, the fan for ventilating the interior of the refrigerator may be a fan. The fan generally has a fast-rotating impeller, the blades of which bring the air by their rotary motion in motion. Usually, the fan of the fan is rotationally driven by an electric motor.
Der sich im Strömungsweg nur über einen Teil dessen Strömungsquerschnitts erstreckende Luftfilter kann sich über das Zentrum des Strömungsquerschnitts erstrecken. Um eine gute Durchströmung des Luftfilters zu gewährleisten, kann dieser direkt vor den Ventilator im Druckbereich platziert werden. Dies hat den Vorteil, dass der Luftfilter zumindest überwiegend in einem Bereich liegt, in dem die höchsten Strömungsgeschwindigkeiten auftreten. Wird der Luftfilter in diesem Bereich mit höchsten Strömungsgeschwindigkeiten angeordnet, so kann bezogen auf den Querschnittsanteil, den der Luftfilter vom gesamten Strömungsquerschnitt einnimmt, ein höherer Luftvolumendurchsatz durch den Luftfilter gefördert werden. So wird ein überwiegender Volumenanteil der Luft durch den Luftfilter geführt und nur ein geringerer Volumenanteil der Luft kann an dem Luftfilter vorbeiströmen. Dies trägt den divergierenden Zielen Rechnung, einerseits einen maximalen Anteil der Luft über den Luftfilter zu reinigen und andererseits einen minimalen Druckabfall durch einen möglichst freien ungehinderten Querschnitt zu erreichen.The air filter extending in the flow path only over part of its flow cross section can extend over the center of the flow cross section. To ensure a good flow through the air filter, this can be placed directly in front of the fan in the pressure range. This has the advantage that the air filter is at least predominantly in an area in which the highest flow velocities occur. If the air filter is arranged in this area with the highest flow velocities, then, based on the cross-sectional portion occupied by the air filter from the entire flow cross-section, a higher air volume throughput can be conveyed through the air filter. Thus, a predominant volume fraction of the air is passed through the air filter and only a smaller volume fraction of the air can flow past the air filter. This takes into account the divergent goals, on the one hand to clean a maximum proportion of air through the air filter and on the other hand to achieve a minimal pressure drop through a free unhindered cross section as possible.
Dazu kann der Luftfilter vorzugsweise im Zentrum des Strömungsquerschnitts im Strömungsweg angeordnet werden. In strömungstechnischer Hinsicht sind die Strömungslinien mit den höchsten Geschwindigkeiten in Querschnittsbereichen zu erwarten, die möglichst weit weg von Wänden des Strömungskanals liegen, also vorzugsweise in einem Zentrum des jeweiligen Strömungskanals liegen. Da der Querschnitt eines Strömungskanals weitgehend beliebige Formen aufweisen kann, ist das Zentrum des Strömungsweges dort zu finden, wo in Abhängigkeit der Querschnittskontur die Strömungslinien mit den höchsten Geschwindigkeiten auftreten. Diese strömungstechnische Eigenschaft ist neben der jeweiligen Kontur des Strömungsquerschnitts auch von der inneren Oberflächenbeschaffenheit, insbesondere von der Anhaftung der Luftströmung an der Oberfläche abhängig. So kann bei einem Luftrohr mit bereichsweise unterschiedlicher Anhaftung der Luftströmung das Zentrum der höchsten Luftgeschwindigkeiten auch außerhalb des geometrischen Mittelpunkts des Kreisquerschnitts liegen. Dies ist auch der Fall, wenn sich der Luftfilter in einer Rohrbiegung befindet.For this purpose, the air filter can preferably be arranged in the center of the flow cross-section in the flow path. In terms of flow, the flow lines with the highest speeds in cross-sectional areas are to be expected, which are as far away from the walls of the flow channel, so preferably lie in a center of the respective flow channel. Since the cross-section of a flow channel can have largely arbitrary shapes, the center of the flow path is to be found where, depending on the cross-sectional contour, the flow lines with the highest speeds occur. This fluidic property is dependent not only on the respective contour of the flow cross section but also on the internal surface texture, in particular on the adhesion of the air flow to the surface. Thus, in the case of an air pipe with regions of different adhesion of the air flow, the center of the highest air velocities can also be outside the geometric center of the circular cross section. This is also the case when the air filter is in a pipe bend.
In allen erfindungsgemäßen Ausgestaltungen ist der Luftfilter in einem überdruckseitigen Abschnitt des Strömungsweges angeordnet. Dies hat den Vorteil, dass gegenüber einer Anordnung des Luftfilters in einem unterdruckseitigen Abschnitt des Strömungsweges der Luftfilter mit höherem Druck beaufschlagt wird, wodurch auch Luftfilter mit einem hohen Strömungswiderstand noch ausreichen mit Luft durchströmt werden können. So ergibt sich beispielsweise bei einem feinporigen Luftfilter, der als Aktivkohlefilter mit katalytischer Wirkung ausgebildet sein kann, ein relativ höherer Strömungswiderstand als bei einem herkömmlichen grobporigen Staubfilter mit einfachem Filtervlies. So ist es erfindungsgemäß insbesondere bei feinporigen Filtern von Vorteil, diesen in den überdruckseitigen Abschnitt des Strömungsweges anzuordnen.In all embodiments according to the invention, the air filter is arranged in a pressure-side section of the flow path. This has the advantage that, compared to an arrangement of the air filter in a vacuum-side portion of the flow path of the air filter is subjected to higher pressure, whereby air filter with a high flow resistance still sufficient air can be flowed through. Thus, for example, results in a fine-pored air filter, which can be configured as activated carbon filter with catalytic effect, a relatively higher flow resistance than in a conventional coarsely porous dust filter with a simple filter fleece. Thus, according to the invention, it is advantageous, particularly in the case of fine-pored filters, to arrange this in the overpressure-side section of the flow path.
Der Luftfilter ist einer Überdruckseite des Gebläses vorgelagert. Dies bewirkt, dass die Luftströmung unmittelbar oder zumindest kurz nach dem Verlassen des Gebläses in den Luftfilter eintreten kann. Dies hat den Vorteil, dass die Luftströmung mit maximaler Geschwindigkeit und Energie in das Luftfilter eingetragen wird. Würde der Luftfilter nämlich sehr weit entfernt vom Gebläse angeordnet werden, so würde noch vor Erreichen des Luftfilters die Luftströmung beispielsweise aufgrund der Wandreibung im Strömungskanal bereits deutlich an Strömungsgeschwindigkeit bzw. Energie verloren haben, so dass die Luft nur mit geringerer Energie in geringerem Maße durch das Luftfilter hindurch geführt werden könnte. Die Anordnung des Luftfilters unmittelbar oder zumindest kurz nach dem Verlassen des Gebläses führt also zu einem hohen Lustströmungsdurchsatz durch den Luftfilter. Im Umkehrschluss bedeutet dies auf Grundlage gleicher Luftfilterleistung einen geringeren Bedarf an elektrischer Energie für den Antriebsmotor des Gebläses.The air filter is upstream of a positive pressure side of the blower. This causes the air flow can enter the air filter immediately or at least shortly after leaving the fan. This has the advantage that the air flow is entered at maximum speed and energy in the air filter. If the air filter were to be arranged very far away from the blower, the air flow would have already significantly lost flow velocity or energy, for example due to the wall friction in the flow channel, so that the air could only be reduced to a lesser extent by the lesser energy Air filter could be passed through. The arrangement of the air filter immediately or at least shortly after leaving the blower thus leads to a high flow of pleasure flow through the air filter. Conversely, this means based on the same air filter performance a lower demand for electrical energy for the drive motor of the fan.
Der Luftfilter ist außerdem in einer der Überdruckseite des Gebläses vorgelagerten Schutzabdeckung integriert. Um den Luftfilter im Strömungsweg zu halten, kann ein gesonderter Halter vorgesehen sein, der einerseits den Luftfilter trägt und andererseits an einer Innenwand eines Strömungskanals befestigt ist. Um jedoch auf einen gesonderten Halter für den Luftfilter verzichten zu können, wird vorgeschlagen, den Luftfilter in eine der Überdruckseite des Gebläses vorgelagerte Schutzabdeckung zu integrieren. Üblicher Weise wird ein vorzugsweise elektromotorisch betreibbarer Ventilator unmittelbar knapp hinterhalb einer Innenwand des den Innenraum begrenzenden Gehäuses installiert sein. Um einen Zugang zu elektrische Energie führenden Leitern durch ein Eingreifen einer Person von dem Innenraum aus zuverlässig zu verhindern, ist generell die Ausblasöffnung des Ventilators bzw. des Gebläses mit einer Schutzabdeckung versehen. Die Schutzabdeckung ist derart gestaltet, dass ein möglichst großer Querschnitt für einen ungehinderten Durchtritt der Luftströmung offen bleibt. Außerdem ist die Schutzabdeckung derart gestaltet, dass ein Eingreifen einer Person, beispielsweise mit den Fingern einer Hand zuverlässig verhindert ist. Dazu ist die Öffnung bzw. sind die Öffnungen der Luftströmung entsprechend eng auszuführen. Üblicher Weise wird die Schutzabdeckung als Gitter ausgebildet, das beispielsweise aus Kunststoff hergestellt sein kann. Erfindungsgemäß wird eine aus Sicherheitsgründen bereits erforderliche Schutzabdeckung funktionsvereinigend als Halter für den Luftfilter genutzt. Dies hat den Vorteil, dass ein gesonderter Halter entfallen kann und somit die Herstellkosten verringert sind.The air filter is also integrated in one of the positive pressure side of the blower upstream protective cover. In order to hold the air filter in the flow path, a separate holder may be provided, on the one hand carries the air filter and on the other hand is fixed to an inner wall of a flow channel. However, in order to dispense with a separate holder for the air filter, it is proposed to integrate the air filter in one of the positive pressure side of the fan upstream protective cover. Usually, a preferably electric motor-operated fan will be installed immediately just behind an inner wall of the housing bounding the interior. In order to reliably prevent access to electrical energy-carrying conductors by intervention of a person from the interior, the exhaust opening of the fan or blower is generally provided with a protective cover. The protective cover is designed such that the largest possible cross-section remains open for an unimpeded passage of the air flow. In addition, the protective cover is designed such that an intervention of a person, for example, with the fingers of one hand is reliably prevented. For this purpose, the opening or the openings of the air flow must be made correspondingly narrow. Usually, the protective cover is formed as a grid, which may be made of plastic, for example. According to the invention, a safety cover which is already required for safety reasons is used functionally as a holder for the air filter. This has the advantage that a separate holder can be omitted and thus the production costs are reduced.
In diesem Falle weist die Schutzabdeckung zum auswechselbaren Halten des Luftfilters eine Aufnahme für den Luftfilter auf. Der Luftfilter ist also auswechselbar gehalten. Dazu wird die Schutzabdeckung nicht plan ausgestaltet, sondern beispielsweise mit einer wannenartigen Aufnahme versehen. Diese Aufnahme kann mit der Schutzabdeckung einteilig ausgebildet sein. Die Aufnahme kann so weit wannenartig in die Schutzabdeckung eintauchen, dass der Luftfilter der insbesondere als eine Filtertablette gestaltet sein kann, vollständig aufgenommen wird. Nachdem der Luftfilter vollständig in die Aufnahmenische eingesetzt ist, kann die verbleibende Durchreicheöffnung mittels eines öffenbaren und schließbaren Deckel verschließbar sein, so dass der Luftfilter festgehalten ist und nicht aus der Schutzabdeckung herausfallen kann.
Die Aufnahmenische der Schutzabdeckung weist eine vom Deckel verschließbare offene Seite auf, die in den Innenraum des Kältegerätes weist. Die verschließbare offene Seite bildet dem gemäß eine Durchreicheöffnung über die ein verbrauchter Luftfilter aus der Schutzabdeckung entnommen und ein neuer Luftfilter eingesetzt werden kann. Damit das Auswechseln des Luftfilters von einem Benutzer selbsttätig durchgeführt werden kann, weist die offene Seite die in den Innenraum des Kältegerätes hinein, so dass der Benutzer bei geöffneter Tür des Kältegerätes vom Innenraum her den Deckel öffnen und den Luftfilter aus der Aufnahme entfernen kann. Der Luftfilter ist insoweit für einen Benutzer durch eine in den Innenraum zugängliche Öffnung zu entnehmen bzw. auszutauschen. Um die notwenige elektrische Sicherheit zu gewährleisten, ist die Ventilatorabdeckung selbst für den Benutzer nicht entnehmbar. Wünscht der Benutzer keine Filterung, so kann das Kältegerät auch ohne eingesetzten Luftfilter in sicherer Weise betrieben werden, d.h. die zur Aufnahme des Luftfilters wannenartig ausbildete Nische ist gegenüber dem Ventilator derart gitterartig versperrt, so dass auch bei entnommenem Luftfilter ein Eingreifen in den Bereich des Ventilators zuverlässig verhindert ist. Der Luftfilter ist leicht austauschbar, da er sehr schnell und gut zu erkennen ist, wenn der Benutzer die Tür des Kältegerätes geöffnet hat. Außerdem ist für den Benutzer sehr leicht erkenntlich, ob ein Luftfilter eingesetzt ist, so dass die luftreinigende Wirkung für den Benutzer im Innenraum des Kältegerätes visualisiert wird.In this case, the protective cover for interchangeable holding the air filter has a receptacle for the air filter. The air filter is therefore kept interchangeable. For this purpose, the protective cover is not designed plan, but provided for example with a trough-like receptacle. This recording can be integrally formed with the protective cover. The receptacle can dip so far into the protective cover that the air filter, which in particular can be designed as a filter tablet, is completely absorbed. After the air filter is fully inserted into the receiving table, the remaining hatch opening can be closed by means of an openable and closable lid, so that the air filter is held and can not fall out of the protective cover.
The receiving recess of the protective cover has an open side closable by the cover, which points into the interior of the refrigeration device. The closable open side forms according to a through-opening over which a spent air filter removed from the protective cover and a new air filter can be used. Thus, the replacement of the air filter can be carried out automatically by a user, the open side into the interior of the refrigerator, so that the user with the door open of the refrigerator from the interior can open the lid and remove the air filter from the recording. The air filter is in this respect for a user to remove or replace through an opening accessible in the interior. To ensure the necessary electrical safety, the fan cover is not removable even for the user. If the user does not want filtering, then the refrigeration device can also be operated safely without inserted air filter, ie the niche formed like a trough for receiving the air filter is blocked in a lattice-like manner with respect to the fan, so that even when the air filter is removed an intervention in the area of the fan is reliably prevented. The air filter is easily replaceable, as it is very quick and easy to recognize when the user has opened the door of the refrigerator. In addition, it is very easily recognizable to the user, whether an air filter is used, so that the air-cleaning effect for the user in the interior of the refrigerator is visualized.
Vorzugsweise ist der Luftfilter als eine Filtertablette ausgestaltet ist, die zum Einsetzen in die Aufnahme der Schutzabdeckung ausgebildet ist. Der Luftfilter ist vorzugsweise als ein Aktivkohlefilter mit katalytischer Wirkung ausgebildet. Durch die Ausbildung des Luftfilters als Filtertablette steht der Luftfilter direkt im Luftstrom und kann somit sein geruchsreduzierendes Potential bzw. seine luftreinigende Wirkung entfalten.Preferably, the air filter is designed as a filter tablet, which is designed for insertion into the receptacle of the protective cover. The air filter is preferably as formed an activated carbon filter with catalytic effect. Due to the design of the air filter as a filter tablet, the air filter is directly in the air flow and can thus develop its odor-reducing potential or its air-cleaning effect.
Die Filtertablette kann dazu eine Größe aufweisen, die in ihrer an der Schutzabdeckung des Gebläses angebrachten Position sich nur über einen Teil des Strömungsquerschnitts der Schutzabdeckung erstreckt. Insbesondere kann die Filtertablette eine derart handliche Größe aufweisen, so dass die Filtertablette mit zwei Fingern einer Hand in die Aufnahmenische im Innenraum des Kältegerätes eingesetzt werden kann. Die Filtertablette kann als eine quaderförmige Tablette ausgebildet sein. Diese Grundform ist beispielsweise bereits bei Reinigungstabletten für Geschirrspüler bekannt. Durch die besondere Gestaltung des Luftfilters als Filtertablette kann der Benutzer zu einer zur Reinigungstablette für Geschirrspüler analoge Handhabung angeregt werden. Im Ergebnis wird damit der Benutzer daran erinnert, den Luftfilter regelmäßig und folglich rechtzeitig auszuwechseln, bevor die luftreinigende Wirkung nachlässt.The filter tablet may for this purpose have a size that extends in its mounted on the protective cover of the blower position only over part of the flow cross-section of the protective cover. In particular, the filter tablet may have such a handy size, so that the filter tablet can be used with two fingers of one hand in the receiving tables in the interior of the refrigerator. The filter tablet may be formed as a cuboid tablet. This basic form is already known, for example, in dishwasher detergent tablets. Due to the special design of the air filter as a filter tablet, the user can be stimulated to a similar to the cleaning tablet for dishwashers handling. As a result, the user is reminded to replace the air filter regularly and therefore in good time before the air purifying effect wears off.
