  • the present invention relates to a refrigeration appliance, in particular a household refrigeration appliance, which is particularly suitable for the storage of desiccated refrigerated goods.
  • a refrigeration appliance in particular a household refrigeration appliance, which is particularly suitable for the storage of desiccated refrigerated goods.
  • the shelf life of non-sterile and airtight packaged foods in a refrigerator is limited by microbial spoilage, chemical and enzymatic spoilage processes, and drying out.
  • Fresh foods such as fruits, vegetables, salads or fresh herbs - in addition to the moisture released by the natural respiration - release moisture into their environment until equilibrium is established between them and the surrounding air.
  • the resulting dehydration of these foods is usually irreversible and causes these foods are judged to be no longer verzehrtauglich long before the consumption would be due to a possible colonization by microorganisms of health concern.
  • a refrigeration device according to the preamble of claim 1 is known.
  • a user has the ability to operate a fan that circulates air between a storage room and an evaporator chamber and a compressor that supplies the evaporator with liquid refrigerant at different times. If he observes condensate in the storage room, he can prevent the return of moisture from the evaporator to the storage room by keeping the evaporator at a low temperature even when the ventilator is at a standstill.
  • the object of the invention is to provide a refrigeration device that can provide improved storage conditions for fresh, moisture-emitting refrigerated goods.
  • the object is achieved by having at least one passage for the supply and / or outflow of air to or from the storage space in a refrigerator, in particular a household refrigeration appliance, with a storage room for perishable refrigerated goods, and in a wall bounding the storage room, and a fan for driving an air flow at the passage a movable closure element between the fan and the storage space is arranged, which circulates in the open position a fan-driven air flow in the storage room and in the closed position the fan-driven air flow over a along an outer side of a wall the storage room running channel leads.
  • the closure element makes it possible to temper the storage chamber either by air exchange or by heat exchange with the circulating in the channel air, in the former case, moisture between the storage chamber and the environment can be replaced, while in the latter case, the exchange of moisture prevented is.
  • the speed of the air flow in the storeroom should never exceed 2 m / s with the closing element open.
  • This can be achieved by a suitable arrangement and dimensioning of the fan; it may still be more appropriate if the passage on the air flow inside the storage room on throttles to a maximum of 2m / s, while with the passage closed in the duct, higher flow velocities may occur.
  • a control unit should be arranged to control the closure element on the basis of the prevailing humidity in the storage room to allow by opening the closure element, the delivery of moist air from the storage room, if this is necessary to prevent condensation in the storage room.
  • control unit should therefore be set up to open the passage when the humidity exceeds a limit at at least one measuring point in the storage room.
  • the fan may conveniently also be controlled based on the humidity in the storage room or on the basis of the prevailing temperature there.
  • the control unit can be set up to put the fan into operation if the difference between the humidity and / or the temperature between two measuring points in the storage space exceeds a limit value.
  • the mixing of the air in the storage space resulting from fan operation when the closure element is open leads to a reduction in the difference, regardless of whether or not the circulating air outside the storage space is simultaneously cooled and / or dehumidified.
  • the path of the fan-driven airflow may pass through an evaporator to cool and / or dehumidify the circulating air at the evaporator if it is cooled during operation of the fan.
  • a second fan may be provided to drive a second airflow in a path leading through an evaporator. By crossing the paths of the two air streams, cooled air at the evaporator can also enter the first air stream and cool the storage space.
  • the storage space is a container which is arranged in a storage compartment of the refrigeration appliance.
  • the container comprises at least a lower and an upper container part and the lower container part without the upper movable, in particular from the storage compartment removed.
  • Components which must be connected to their power supply or signal lines, such as the shutter, the fan or a sensor are preferably provided on the upper tank part. So they do not hinder the movement of the lower container part.
  • the fan may also be located on a wall of the storage compartment surrounding the container.
  • the control unit may be configured to keep the passage of the container closed while the defrost heater is in operation, and thus the entry of relatively warm, humid air into the interior of the container during defrosting.
  • the wall of the storage space may be provided on at least part of its surface with an insulating heat storage medium.
  • the heat storage medium is suitably chosen so that a phase transition temperature of the heat storage medium coincides with the operating temperature of the cold reservoir.
  • the heat storage medium is disposed on that part of the wall of the storage room, which also limits the channel.
  • Another measure that can minimize temperature gradients and fluctuations in the storage space is that the wall of the storage space comprises at least a portion of its surface an outer wall, an inner wall and an insulating gap therebetween.

  • Fig. 1 shows the plate 14 in its open position; in its closed position, it lies on the passage 13 of the upper container part 6.
  • the upper container part 6 is suspended on a ceiling 15 of the storage compartment 3 with vertical play, for example with the aid of engaging in slots hook 16, to allow close contact of the sealing flanges 1 1, 12, even if the container parts 5, 6 not are placed exactly above and below each other.
  • a line bundle 21 connects the actuator 18 and the sensors 19, 20 with an electronic control unit of the refrigerator, not shown here, based on measurement data of the sensors 19, 20, the fan 17, the actuator 18 and, in a usual way, a compressor not shown here the refrigeration device and, if it is a Nofrost refrigeration device to control a second fan for circulating air between an evaporator 28 and the storage compartment 3.
  • the control of the fan 17 and the actuator 18 by the control unit can be done in different ways. In the simplest case, the fan 17 is continuously in operation to keep in motion when the plate 14 is in the closed position, a circulating in the channels 44, 45 around the container 4 in air flow.
  • the air flow exchanges heat with the interior of the container 4 through its walls, it reduces any temperature and humidity gradients within the container 4, so that the air humidity value detected by the humidity sensor 19 locally at its installation location for the entire volume of the Container 4 is representative. If this value exceeds an upper limit of, for example, 85% + ⁇ rH, where ⁇ is a small positive value, for example 0.5%, then the control unit activates the actuator 18 in order to open the passage 13. Thus, the air flow in the container 4 is deflected in, and moist air in the container 4 is replaced by drier, flowing from the outside air. Thus, the humidity in the container 4 is lowered far enough to prevent the precipitation of condensation inside the container 4.
  • the actuator 18 is driven again to close the passage 13. Consequently, the humidity in the container 4 varies in a very narrow range of 2 ⁇ , and the amount of moisture released from the refrigerated goods 23 stored in the container 4 to maintain an equilibrium value of the humidity is very small.
  • the humidity limit may also be set to values other than the above 85% RH. The limit should be at least as high as the equilibrium humidity of the chilled goods 23, but should also be far enough below 100% rH to condensation in relatively cool, possibly by Refrigerated goods 23 to be able to exclude from the container 17 in the container 4 directed air flow of the fan 17 shielded areas of the container 4.
  • a tray 36 may be disposed in the container 4 spaced from its walls and bottom such that the plate 14 is in the open position into the container 4 deflected air circulate in a gap 37 between the lower container part 5 and shell 36, pass through openings 38 of the shell 36 and so can reach the refrigerated goods 23 from all sides.
  • the fan 17 is not continuous, but needs-oriented in operation. Need for operation of the fan 17 is when there is a significant gradient of the temperature or humidity in the container 4. On the existence of a temperature gradient can, for. B. are closed when the measured value of the temperature sensor 20 differs significantly from that of a temperature sensor, not shown in the figure, which is mounted in a conventional manner to a wall of the storage compartment 3 and serves to control the compressor operation.
  • a gradient of temperature or humidity can also be measured directly in the container 4 if it has at least two sensors of the same type at different locations. Since, on the one hand, cold air tends to collect at the bottom of the container 4 and, on the other hand, the container is exposed to a heat inflow predominantly at its front, while it is from behind, either through a cold-wall evaporator or through a channel in the rear wall 29 Cooling air supplied from a Nofrost evaporator is most likely to form a temperature or humidity gradient between a relatively cold or wet area in the bottom or rear wall of the container 4 and a relatively warm or dry area in a front upper one Corner of the container 4.
  • a second sensor should consequently be spaced vertically and / or in the depth direction from the sensors 19, 20 and preferably at the lower container part 5, in particular at the rear wall 9 thereof. If such a sensor is fixedly mounted on the lower container part 5 and this is to be removed for handling thedeguts 23 from the refrigerator, there is the problem to transmit the signals of such a sensor to the control unit. In the embodiment shown in Fig. 2, this problem is solved by 9 in the back wall - otherwise identical to that of FIG. 1 - lower container part 5, a large-area opening 24 is formed around which, when the container part 5 is not, as shown in the figure, partially withdrawn, but placed tightly closing under the upper container part 6, a elastic bellows 25 sealingly abuts against the rear wall 9. In this bellows 25 mounted temperature and / or humidity sensors 26, 27 are fixed with respect to the body 1 and fixed lines to the control unit connected, but are when the door 2 is closed and the container parts 5, 6 are placed close to each other exposed to the air of the container 4.

  • This housing 41 may, as shown in Fig. 4, be tapered forward so that it is easily and safely inserted into the opening 24 and a stop position, to which the container 4 in the storage compartment 3 is inserted and in the opening 24 is substantially sealed by the housing 41, is defined by contact of the housing 41 with the edges of the opening 24.
  • the engaging in the stop position in the container 4 tip of the housing 41 is broken to allow an exchange of air between the interior of the container 4 and housed in the housing 41 sensors 26, 27.

  • the presence of temperature and humidity sensors 19, 20, 26, 27 spaced apart in the direction of the temperature or humidity gradient allows, for example, control of the fan 17 and the actuator 18, in which the fan 17 is always switched on when the difference between the humidity values measured by the air humidity sensors 19, 27 exceeds a limit value of, for example, 4% rH or the difference between the measured values of the temperature sensors 20, 26 exceeds a limit value of 0.3 K, and the fan 17 is switched off again as soon as both Limit values are exceeded, and the actuator 18 opens the passage 13 when at least one of the humidity sensors 19, 27 reports an increase in humidity to over 85% rH + ⁇ or the passage 13 is closed again, if both humidity sensors 19, 27 less than 85% rH - ⁇ report.
