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 13 consists of a fan 14, to the fan shaft 15 a plurality of blades 12 are arranged.
  • 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).
