Definitions

  • the invention relates to a household refrigerator with at least one lockable by a door Cold room, in the refrigerated goods container, an evaporator and this at times with Indoor air-supplying fans are provided, which are natural, due to the cooling capacity of the evaporator-induced convection current is arranged.
  • Such cooling devices are both from GB-A-867 292 and from US-A-2 532 816 known.
  • the shortest possible defrosting time is sought.
  • this solution has the disadvantage that the two subjects are different Temperature-connecting air duct, regardless of which of the both compartments are accessed more often, the humidity penetrating into the respective cooling compartment condenses on the evaporator and freezes it prematurely. It is also for this Solution usually requires a complex installation of a second fan.
  • a fan is provided in this shaft in the area of the freezer compartment Cooling operation to keep the temperature in the freezer forcibly circulates the air and feeds via the evaporator, but stands still in defrost mode.
  • the invention has for its object to take measures that the defrost on simple support and speed up while at the same time the disadvantages of the stand avoid technology.
  • the object is achieved according to the invention in that the fan both the cooling air in Cooling operation as well as in defrosting operation is forced, with the cooling air through the Arrangement and design of the refrigerated goods container and the fan in the area of the cold room walls and is guided along the door over its entire height and width.
  • the solution according to the invention has the advantage on the one hand. that no second fan through elaborate and yet often installed the thermal insulation reducing installation and on the other hand the advantage that the subjects have different temperatures are thermally separated.
  • the fan is arranged below the evaporator so that the Evaporator is in the suction air flow of the fan.
  • Such a solution has the advantage that the flow direction generated by the fan with the natural resulting from the warmer and colder areas within the compartment Air circulation coincides, so that both flow directions overlap and don't work against each other.
  • the fan is designed as an axial fan.
  • This solution has the advantage that the fan in a confined space within the refrigerator can be integrated. so that valuable storage space is preserved in the refrigerator compartment. Such are also Fan particularly inexpensive.
  • the fan on the blow-out side with a blow-out air via the Width of the refrigerator compartment leading cover is provided.
  • the with the arranged in the refrigerator compartment Refrigerated goods containers cooperate such that the blow-out air over the door-side area is fed away to the evaporator.
  • a solution according to this feature has the advantage that the one generated by the fan Air flow is essentially guided to the evaporator and evenly over the entire evaporator surface is conveyed. Also inside the refrigerator compartment an air mixture that is as comprehensive as possible between the colder and warmer air areas reached.
  • a household refrigerator 10 shown in FIG. 1 is provided with a closable by a door 11, heat-insulated housing 12 equipped. in which two by a heat insulated Separating plate 13 arranged thermally separated compartments of different temperatures are.
  • the compartment above the partition plate 13 serves as a normal cooling compartment 14 and is in the usual way with serving as a shelf 15, while that below the partition plate 13 arranged cooling compartment is designed as a zero-degree compartment 16.
  • the zero-degree compartment 16 is provided with several superposed ones, some of which are designed as extracts Containers 17, 18 and 19 provided for receiving the goods to be stored there (as can also be seen in particular as FIG. 2).
  • both cooling compartments 14 and 16 on their rear wall each with a flat evaporator 20 and 21 in the form of a so-called cold wall evaporator fitted.
  • the zero-degree compartment 16 has an axial fan trained fan 22 (this is only hinted at here), which both in Cooling operation of the refrigerator 10 to achieve the cooling air within the zero degree compartment 16 circulates a temperature distribution that is as uniform as possible and via the evaporator 21 promotes, as well as in the defrost operation of the refrigerator 10 at certain time intervals automatically initiated defrosting of the evaporator 21 by forced circulation the air inside the compartment 16 supports.
  • the fan 22 arranged at a distance below the evaporator 21 is laterally one stepped projection 23 recessed corner area 24 arranged and with a cover 25 provided with fasteners not specified in the housing wall is anchored (cf. in particular also FIG. 3).
  • the one installed under cover 25 Fan 22 is arranged with respect to the evaporator 21 so that it is on the suction side Air flow of the fan 22 is.
  • the exhaust air flow of the fan is 21 in its vicinity through the cover 25, which for this purpose Air guidance devices described in more detail below, which is on the inside the walls of the cover adapted to the contours of the step-like projection 23 25 are arranged.
  • the lower edge of the vertical assigned to the front of the step-like projection 23 Wall 26 of cover 25 forms a nozzle-like shape with the bottom of housing 12 Air outlet 27, while its horizontal associated with the top of the projection 23 Wall 28 with a vent that runs near the rear wall of the housing 12 29 having air inlet is provided.
  • the cover is for influencing the blow-out air flow generated by the fan 22 25 on the inside with air guiding devices in the form of an impeller of the fan 22 cover 30 from above and on the inside of its upright wall with a fan shape arranged ribs 31 to 34 provided an even air distribution have different design above the floor.
  • Deviating from the illustrated and described embodiment example can also be provided be that the bottom of the housing 12 and / or the bottom of the spaced above it arranged container 19 with fan-like starting from the air outlet of the cover 25 Air guiding ribs are provided, which serve to prevent the outlet 27 from the nozzle-sar distribute outgoing air flow evenly over the entire surface of the floor.
  • the fan can be provided 21 not in a corner area. but to arrange in the middle of the step-like projection 23, or use a cross-flow fan instead of the axial flow fan.
