Definitions

  • the invention relates to a cooling device with an inner container, in which an evaporator and a compressor are arranged.
  • Object of the present invention is therefore to provide a cooling device that allows the storage of a stored goods that is sensitive to changes in humidity. It is to be created - in other words - a refrigerator that is suitable for storage of cigars, pharmaceuticals or other sensitive to climatic fluctuations stored goods.
  • This object is achieved on the basis of a cooling device according to the preamble of claim 1 by the combination with the features of the characterizing part of claim 1.
  • a second inner container is provided on a cooling device with a first inner container, in which an evaporator is arranged.
  • the first inner container surrounds the second inner container such that a gap between the first and the second inner container is formed.
  • the stored goods are stored inside the second inner container.
  • the second inner container Due to the provision of the second inner container, an air-tight separation between the cooling system and storage space is created. Thus, the humidity within the second interior during the compressor run time can no longer be reflected on the evaporator, which leads to the sudden cooling of the humidity in conventional refrigerators. Due to the provision of the second inner container and the space between the first and second inner container uniform cooling of the interior is ensured within the second inner container. Drop formation of precipitating moisture on the rear wall of the second inner container does not occur due to the dynamic aeration.
  • a moistening unit can be arranged within the second inner container. Due to the provision of this humidification unit, which is known per se in structure, a desired air humidity can be set in the interior of the refrigerator, which is enclosed by the second inner container.
  • the humidification unit is controlled by an electromechanical or electronic humidistat with adjustable hysteresis. This means, that the maximum permitted fluctuation of the humidity can be adjusted according to the stored goods to be stored.
  • a dehumidification flap is arranged in the wall of the second inner container, which allows a connection to the intermediate space between the first and the second inner container. By appropriately opening the flap, moisture-laden air can flow into the intermediate space between the first inner container and the second inner container, so that the moisture content in the interior of the second inner container can be reduced.
  • the dehumidification flap can also be controlled by the hygrostat.
  • a ventilation device may be provided in the intermediate space between the first and the second inner container in order to circulate the air in the intermediate space.
  • the arranged in the first inner container evaporator is advantageously foamed.
  • an evaporation tray can be arranged such that in the region of the evaporator forming water can drain into the evaporation tray.
  • the evaporation tray may advantageously be arranged together with the compressor in a receiving area which is recessed in the lower area of the first inner container.
  • a connecting channel for discharging the collecting in a funnel-like extension of the connecting channel water can be provided.
  • FIG. 1 is a schematic side view of a cooling device according to a first embodiment of the invention
  • FIG. 2 is a schematic sectional view of the refrigerator of FIG. 1 seen from the front
  • FIG. 3 is a sectional view corresponding to FIG. 1 through a cooling device according to another embodiment of the invention.
  • FIG. 4 shows a sectional view through the cooling device according to FIG. 3 in the same view as in FIG. 2,
  • Fig. 5 is a sectional view corresponding to FIG. 1 by a cooling device according to another embodiment of the invention.
  • FIG. 6 is a sectional view through the cooling device according to FIG. 5 in the same view as in FIG. 2.
  • a cooling device 10 which has a first inner container 12. With the inner container a refrigerator door 14 is connected in the usual way via hinges. On the rear wall of the inner container 12, a large-scale evaporator 16 is also foamed in a known manner. In the lower rear area encloses the foamed housing 13 a receiving space 18 in which a compressor 20 and an evaporation tray 22 are arranged. As far as corresponds to the structure of the refrigerator according to Figures 1 and 2, the structure of already known refrigerators.
  • the inner container 12 surrounds a second inner container 24 such that a gap 26 between the first inner container 12 and the second inner container 24 is formed.
  • a ventilation device 28 is provided, with which the air located in the intermediate space is set in motion in the direction of the arrows shown in FIGS. 1 and 2.
  • the air in the intermediate space sweeps over the intermediate wall 30 between the intermediate space 26 and the inner space 32 enclosed by the second inner container 24.
  • a humidification unit 34 which is already known in its construction, is arranged in the floor area.
  • a desired air humidity in the interior 32 of the cooling device 10 can be adjusted via the humidification unit 34, which can be controlled by a hygrostat, which is no longer shown here.
  • a dehumidification flap 36 which can advantageously be activated via the hygrostat, is provided in the intermediate wall 30. This makes it possible after their opening, humid air from the interior 32 to flow into the gap 26.
  • the first inner container 12 in the lower and rear region of the cooling device 10 forms a shoulder 38 surrounding the receiving space 18.
  • a connecting channel 40 is formed which connects the intermediate space 26 and the receiving space 18.
  • the evaporation tray 22 which is seated on the compressor housing in the embodiment shown here, arranged.
  • the connecting channel 40 expands to form a funnel-shaped receptacle 42.
  • condensation water forming in the region of the advantageously foamed-in evaporator 16 can collect. This condensate flows by gravity through the connecting channel 40 and drips into the evaporation tray 22nd
  • the embodiment according to FIGS. 3 and 4 substantially corresponds to that according to FIGS. 1 and 2.
  • the essential difference here is that that the intermediate space 26 between the first and the second inner container does not surround the entire inner container (except for the area of the door). Rather, the gap 26 is arranged in this embodiment only in the side area.
  • the ventilation device 28 is arranged in the lower region of the cooling device 10.
  • no evaporator plate is arranged in the rear wall region of the inner container. Rather, here the evaporator 16 are each foamed laterally in the region of the inner container 12. Due to the arrangement of the gap 26 ensures that the air flow circulated through the ventilation device 28 flows over the cooled surface on the side wall to allow the best possible heat transfer.
  • the dehumidifying flap 36 is arranged in the intermediate wall in the region of the side wall of the inner container 12.
  • the cooling device according to FIGS. 5 and 6 essentially corresponds to that according to FIG. 3.
  • the intermediate space 26 between the inner container 12 and the second inner container 24 through which the air corresponds to the arrows in FIG 5 or 6 flows, not drawn into the lower portion of the refrigerator 10, ie in the area in which the humidification is located. Rather, the gap 26 extends here only, as shown by the arrows, above the lower region in which the moistening takes place.
  • the ventilation device 28 is therefore also located in the upper region of the refrigerator, as is apparent from Figures 5 and 6.
