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.
- the invention also relates to an air filter which is designed as a filter tablet.
- a refrigerator for household purposes is known. 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 shown in DE 75 16 271 U1.
- 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 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 panel for selectively opening or closing the outlet, a filter unit for filtering air sucked through the inlet, a blower for sucking air via the 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 its top.
- a refrigerator in which an air filter is disposed in a pressure-side portion of a flow path is shown in JP2005090910A.
- 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 through the disinfection filter completely.
- 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 to a possibility of saving electrical energy in that, on the one hand, no additional second fan is required and, on the other hand, the necessarily existing first fan can be operated with the lowest possible pressure drop, as a result of which the consumption of electrical energy of this first fan 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 rapidly rotating impeller, the blades of which cause the air to rotate by virtue of its rotary 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, it can be placed directly in front of the fan in the pressure area. 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 guided through the air filter and only a smaller proportion by volume 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 lie as far away as possible from the walls of the flow channel, ie, 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 point of the circular cross section. This is also the case when the air filter is in a pipe bend.
- the air filter can be arranged in a section of the flow path which is on the overpressure side.
- 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 even air filter with a high flow resistance still sufficient air can be flowed through.
- the air filter may be arranged upstream of a positive pressure side of the fan. 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 clearly lost flow velocity or energy before the air filter was reached, for example due to the wall friction in the flow channel, so that the air would only to a lesser extent with less energy could be passed through the air filter.
- 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 can be integrated into a protective cover located upstream of the overpressure side of the fan.
- 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 may have a receptacle for the air filter.
- the air filter is kept exchangeable.
- 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 into the protective cover in a trough-like manner so that the air filter, which in particular can be designed as a filter tablet, is completely absorbed.
- the remaining hatch opening can be closed by means of an openable and closable lid, so that the air filter is held tight and can not fall out of the protective cover.
- the receiving recess of the protective cover may have an open side which can be closed by the cover and 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 can not be removed even by the user.
- the refrigeration device can be operated safely even without an air filter inserted, i. the trough formed to receive the air filter trough-like is locked in such a grid-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 invention also relates to an air filter, which is designed as a filter tablet, which is designed for insertion in a, preferably closable with a lid receiving tables a protective cover of a blower.
- 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.
