Definitions

  • the present invention relates to a refrigerator with air circulation.
  • air circulation can serve to convey warm air from a storage space of the refrigeration device into an evaporator chamber remote from the storage space and cold air back from this into the storage space, or merely to compensate for temperature differences in the storage space by air movement.
  • germs can develop over time, giving the air an unpleasant odor.
  • it is known per se to accommodate in a refrigeration device with a storage room for refrigerated goods and in a communicating with the storage room chamber fan in the chamber and an air filter, which is flowed through by the circulating air from the fan to filter out unpleasant odors. The presence of such a filter is often not noticed by the users.
  • the object of the invention is to provide a refrigeration device of the type mentioned above, which avoids the disadvantages mentioned above.
  • the object is achieved in that the air filter is arranged accessible in a passage between the chamber and the storage space from the side of the storage room forth.
  • a uniform interior of the refrigerator is divided by a fan cover mounted in it in the storage room and the chamber.
  • a protective grid expediently extends between the filter and the fan.
  • This protective grid is expediently part of the Ventiltorabdeckung. Conveniently, the protective grid can simultaneously serve as a carrier for the filter.
  • the filter is received in a recess of the protective grid.
  • the filter is preferably secured by a removable perforated cover so that the air can flow through the protective grid, the filter and the cover (or vice versa) in turn.
  • the protective grid is bulged into the storage room inside.
  • the air filter fills the flow cross-section of the fan only incomplete, so that always only a part of the air circulated by the fan flows through the filter.
  • the fan power required to maintain a desired air flow rate can be kept low.
  • the air filter is arranged centrally in the flow cross-section of the fan, so that it only slightly influences the distribution of the air exiting the fan chamber in the storage room.
  • FIG. 1 is a front view of a fan unit for a refrigerator according to the present invention.
  • FIG. 2 is an exploded partial view of the fan unit;
  • FIG. and Fig. 3 is a horizontal section through the fan unit.
  • Fig. 1 shows a front view of a fan cover 1, which is provided to be mounted on the upper edge of a rear wall in the inner container of a refrigerator, in particular a bottle storage cabinet.
  • a central opening 2 is formed, behind which a known axial fan 3 is arranged.
  • Horizontal ribs 4 extend over the entire width of the shield, from a closed-walled field 5 to the left over the central opening 2 to a second closed-walled field 5 on the right side.
  • the ribs 4 are bulged into the storage space of the refrigerator and form with vertical ribs 6 a rigid grid.
  • a recess 7 is formed with a perforated bottom surface facing the fan 3.
  • the recess 7 is made to receive a catalytic activated carbon filter 8.
  • the filter 8 is held in the recess by a cover 9, which is also lattice-shaped, with the horizontal and vertical ribs 4, 6 continuously extending ribs 10, 11, designed.
  • the two lateral vertical ribs 1 1 of the cover 9 each carry a engaging in the recess 7 locking tongue 12.
  • the locking tongues 12 are respectively
  • the front side of the axial fan 3 is almost flush with the two side panels 5.
  • the ribs 4 between the fields 5 projecting arcuately into the storage space of the refrigerator, between these and the fan. 3 Place to accommodate the filter 8 created.
  • a gap which is closed at the bottom by a bottom plate 16 of the fan cover 1.
  • a formed in the bottom plate grate 17 allows access of air from the storage room to the fan. 3
  • the air expelled from the fan 3 flows to a large extent around the filter 8; only a small part flows through the filter 8. However, this is sufficient to absorb disturbing odors.
  • a user To replace the filter 8, a user must solve the cover 9, for example by unlocking the locking tongues 12 by means of an inserted between them and the side walls 13 of the recess 7 screwdriver. Since the grid formed by the ribs 4, 6 itself does not need to be opened at any point, accidental contact with the fan when replacing the filter 8 is excluded.
