Definitions

  • the present invention relates to a cooling device, in particular a household refrigerator.
  • a cooling device according to the preamble of claim 1 is known from DE 41 31 211 C1.
  • the air circulation device of this cooling device sucks the air from the interior and lets it through a by extending along the rear wall of the refrigerator Flow inside through a partition separated channel, on the outside of it Wall of the evaporator is arranged.
  • a cooling device is indeed suitable Design of the channels an even temperature distribution in the interior achievable, but this is at the expense of the useful volume of the interior, since the Flow channels must be separated from this.
  • the intense Airflow helps keep moisture condensed on the evaporator Phases of the evaporator is distributed again in the interior and so the dew formation promotes refrigerated goods stored in the interior.
  • the object of the present invention is to provide a cooling device with a simple structure, in which the amount of water evaporable from the cooled inner wall and so that the humidity in the interior can be kept low.
  • the object is achieved in that the area of the inner wall occupied by the evaporator compared to conventional refrigeration devices, so that at least a quarter or even half of the area of the wall remains free from the evaporator, and that the free area forms an upper area of the wall.
  • Air exchange causes the Effectiveness of cooling in the lower area, in particular in the area of a vegetable compartment, not reduced, and effective cooling in the upper area, in which the Evaporator does not extend.
  • the air circulation device circulated air flow directly over the entire surface of the evaporator to be led; a partition that has a flow channel on the entire surface of the evaporator separating from the interior, as described in DE 41 31 211 C1, is therefore not mandatory. Because no voluminous flow channel is separated from the interior good space utilization is achieved.
  • the evaporator of the cooling device according to the invention is preferably a cold wall evaporator trained, i.e. it is between the wall of the interior and one behind it embedded thermal insulation layer.
  • the air circulation device is preferably arranged and constructed so that one of their flow distribution generated in the interior is a zone of maximum flow velocity at a distance from the wall equipped with the evaporator. That on the wall of the evaporator it can be relatively "windless”, so on it Thaw the deposited moisture as far as possible when the evaporator is at a standstill, drain and can be removed from the interior of the refrigerator, instead of again to evaporate in this.
  • This type of flow distribution does not exclude the cooling device according to the invention for effective air circulation with flow channels separated from the interior is equipped in which also higher flow speeds than in the interior may occur.
  • the interior of the refrigerator is in an upper area and one of at least one box-like container occupied lower compartment, and the evaporator extends into the area of the compartment to include the contents of the container effective cooling.
  • the outer sides of the container are preferably at least on part of its area from an air flow caused by the air circulating device lapped.
  • a cooling device 10 designed as a multi-temperature refrigerator has in the middle Section of its heat-insulated housing 11 has a door 12 on its front side closable interior 13. The one struck on the side of the door opening on the housing 11 Door 12 is on its inside with projecting, one above the other Provide storage compartments 14 which serve to hold small-sized items to be refrigerated.
  • An upper region 17 of the rear wall which is about at least a quarter, better one third and in the example shown here about half the height of the interior remains free from the evaporator 15; the evaporator 15 extends down to under a partition plate 18 which divides the interior 13 into an upper region 19 and a lower one Compartment 20 divided.
  • the lower compartment 20 is arranged by one or two side by side Pull-out boxes 21 filled for vegetables or the like.
  • the Partition plate 18 is a closed plate, e.g. made of glass that has a horizontal passage 27 limited along the top of the box 21.
  • a second passage 28 runs between the front of the box 21 and the door 12, below the box bottom and between the back of the box 21 and the back wall 16.
  • An air circulation device 22 in the form of a fan is under the ceiling of the interior 13, in this embodiment in the vicinity of the door 12, arranged and generated a downward airflow 24.
  • the downward directed air flow 24 generated by the fan 22 becomes on shelves 23 of the interior, which is preferably designed as a grid because of the good flowability and, if necessary, on (not shown) on the shelves 23 Refrigerated goods are scattered, so that a widely distributed, diffuse air flow separates the partition plate 18 reached, flows in part through the passages 27 and 28 and along the rear wall 16 slowly flows up again. Since the shelves 23 do not block the air flow, they can extend directly to the rear wall 16.
  • the shelves 23 can also be closed, e.g. in the form of Glass plates.
  • there are gaps 25 between the rear edges of the shelves 23 and the rear wall 16 are provided so that the upward air flow along the Rear wall 16 can run through the column 25.
  • the fan 22 can do so at various other locations on the refrigerator be arranged so that it generates the required circulation flow inside it.
  • Conceivable is also to drive the circulating flow in the opposite direction so that this flows downward on the evaporator 15 and first on the partition plate 18 to the lower compartment 20 hits before it rises again along the door 12.
  • This direction of circulation is not exclude that partial areas of the evaporator by a direct or little Scattered air flow can be taken by the fan 22, so that in these areas condensed moisture can evaporate back into the interior 13.
  • this can be accepted in moderation, since, as described above, already through the Reduction of the evaporator area a more efficient drainage of condensate the interior 13 results.
  • FIG. 2 shows a schematic front view of a cooling device according to a second embodiment the invention elements of this refrigerator, which are also in the refrigerator of Fig.1 occur are provided with the same reference numerals as there and are not described in detail again.
  • the evaporator 15 does not extend over the entire width of the rear wall 16, instead an edge region of the rear wall remains 16 free from the evaporator, and extends in this edge area behind the rear wall 16 in this embodiment, a flow channel 29 extends over the entire Height of the interior 13. It is at its upper and lower ends and in Height of the passage 27 between the plate 18 and the pull-out box (not shown) provided with air inlet and outlet slots 30, 31.
  • a fan (not shown) is in the flow channel 29 between the level of the plate 18 and its upper Arranged at the end.
  • the fan generates an upward air flow in the flow channel 29, see above that air is drawn out through the lower slots 30 and through the upper slots 31 again is expelled.
  • the flow around the pull-out box is also off the upper region 19 of the interior is supplied with moderately cold air, while freshly cooled air sucked off at the evaporator 15 and at the upper end of the flow channel 29 is expelled again.
  • This is an effective cooling of the entire upper area 19 is guaranteed and at the same time the content of the pull-out box protected from hypothermia by the closely adjacent evaporator 15.
  • FIG. 3 shows a modification of the illustration in FIG. 2, in which the flow channel 29 extends centrally over the rear wall 16.
  • the horizontal section of FIG. 4 shows the rear wall 16 bulges into the interior 13 in the region of the flow channel 29, and the air flow in the flow channel 29 runs directly along the surface of the evaporator 15.
  • the effect in this embodiment is essentially that same as that of Fig. 2; the only difference is that the air passes undergoes additional cooling through the flow channel 29. You can in the flow channel 29 quite higher flow speeds than in the interior 13 occur; however, this is not critical to the desired drying effect.
  • the lateral sections 32 of the evaporator 15 on both sides of the flow channel 29, each only through the material of the rear wall 16 are separately in direct thermal contact with the interior 13 and the form a predominant part of the surface of the evaporator by means of a suitable flow distribution in the interior are protected from the flow, so that there is condensate can collect and flow undisturbed at these sections 32.
