Definitions

  • the present invention relates to a refrigerator and / or freezer with a device body having an inner wall, behind which a cooling element of the cooling circuit is arranged for cooling the interior, and with a vorgeblendeten in the interior of the device body of said inner wall of the device body cover plate, wherein the cover plate by releasable fastening means held in the interior and can be removed from the interior, so that the interior is optionally available with or without cover plate.
  • the inner rear wall of the device body behind which is arranged regularly the evaporator of the cooling circuit, vorzublenden a separate cover plate in the interior of the refrigerator in order to eliminate the problems mentioned.
  • a separate cover plate between this vorgeblendeten cover plate and the actual carcass inner wall remains a gap, so that the condensation and frost formation on the actual inner wall surface may still occur, but does not overlap on the cover plate.
  • the advantages achieved by this solution are paid for by loss of space, since the vorgeblende cover plate reduces the usable interior space, especially as between the cover plate and the body inner wall, a gap is provided. Although this is generally acceptable because the interior is often not completely filled, but then annoying when the full storage volume is actually needed.
  • the present invention has the object to provide an improved refrigerator and / or freezer of the type mentioned, which avoids the disadvantages of the prior art and further develops the latter in an advantageous manner.
  • the problem of frost and condensation on the inner rear wall to be solved, while still providing the maximum storage volume of the device is available if necessary.
  • the cover plate is held by releasable fastening means in the interior and removed from the interior, so that the interior is optionally available with or without cover plate.
  • the device receives a variable interior volume, which can be increased by removing the cover plate, if necessary, to have the maximum possible storage space available.
  • the problem of condensate and frost formation on the inner wall of the carcass can be eliminated by this variable interior concept and, nevertheless, if required, the maximum possible net volume can be made available.
  • the refrigerator and / or freezer has a control device that takes into account the refrigeration effects of removing or inserting the cover plate.
  • the control device can at least one operating parameter at least a device component which is effective in terms of cooling changes depending on whether the cover plate is inserted in or removed from the interior.
  • the controller adjusts the operation of the necessary device components to the presence or absence of the cover plate.
  • control device can change a temperature switching value of the cooling unit when the cover plate is removed from the interior.
  • control device can change the operating mode of a fan, which is provided in the interior of the device.
  • a fan is arranged such that an air circulation takes place in the gap, which is provided between the device body inner wall and the vorgeblendeten cover plate.
  • the fan can be arranged in the region of the upper end of the cover plate and / or under a ceiling of the inner space, so that the air circulation caused by the fan sweeps past behind and / or in front of the cover plate.
  • the control device can change the operating mode of the fan differently depending on its installation situation. If the fan is fixedly mounted in the interior, the switching times or operating intervals can be changed by the control device, depending on whether the cover plate is inserted or removed.
  • the fan may also be mounted on the cover plate itself, so that it can be removed together with the cover plate.
  • the controller may simply deactivate the fan control routine when the cover plate is removed.
  • a detection device be provided, which detects whether the cover plate is inserted or removed.
  • the control device alters the mentioned, at least one operating parameter of at least one device component which is effective in cooling technology as a function of a signal of the detection device.
  • the detection device can basically be designed differently. According to an advantageous embodiment of the invention, the detection device operates without contact.
  • a reed switch can be provided which detects the presence of the cover plate in the interior.
  • the releasable fastening means for the cover plate can basically be designed differently.
  • the fastening means are advantageously without tools only by hand solvable or vice versa closing or fastened.
  • the fastening means can hold the cover plate positively and / or non-positively in the interior at the desired position in front of the inner wall to be covered.
  • a particularly easy-to-use yet stable attachment is provided by latching means by which the cover plate can be locked in the interior at the desired position.
  • the fastening means can basically be provided at different locations. In particular, they may be provided on the device body and / or the cover plate itself. Alternatively or additionally, fastening means may also be provided on storage shelves and / or cooperating therewith on the cover plate, so that the cover plate can be fastened to storage shelves or shelves which can be inserted into the interior of the appliance body.
  • locking means can be provided on the device body receiving recesses into which the cover plate can be used.
  • the cover plate can be inserted with one side in a receiving recess and locked on the opposite side with latching means provided there. It can be provided to thread the cover at the bottom and to lock up or alternatively thread the top and to lock down. Alternatively, the cover can also be threaded laterally and also laterally, but opposite locked.
  • the cover plate itself can basically be designed differently. It can be designed as a simple glass, plastic or metal plate, but also as a plate with at least one insulation layer of Styrofoam and / or PUR. If the partition panel is made of glass, safety glass or mirror glass can be used in addition to simple glass, whereby special design effects are possible.
  • the cover plate may be formed differently large. In a further development of the invention, it is at least designed so large that it covers the region of the inner wall, behind which lies the evaporator of the cooling circuit.
  • the cover plate can be arranged in particular aligned vertically in front of the rear wall of the device body.
  • the cover plate need not necessarily be just in the sense of a mathematical level, but may also have elevations and / or have bends.
  • the cooling device 1 shown in the figures has a substantially cubic device body 2, the housing is formed in the usual manner insulating. On the back 3 of the device body 2 while an evaporator 4 of the cooling circuit is provided, which may be foamed into the insulation of the device body 2, so that it comes to rest behind the inner rear wall 5 of the device body 2.
  • a cover plate 6 is vorgeblendet, which is arranged in the interior 7 of the device body 2 upright in front of said rear wall 5.
  • the cover plate 6 is arranged substantially parallel to the rear wall 5, but spaced therefrom, so that between the rear wall 5 and the cover plate 6, an air circulation channel 8 is formed.
  • the cover plate 6 is arranged hanging, ie it is not in the illustrated embodiment with its lower edge on the bottom of the device body 2. Between the bottom 9 of the device body 2 and the cover plate 6, the gap 10 remains, see. FIG. 1 ,
  • a fan 12 is arranged on the ceiling 11 of the device body 2 at the rear end of the interior 7, by means of which an air circulation around the cover plate 6 can be achieved around, wherein said air circulation channel 8 between the cover plate 6 and the rear wall. 5 is ventilated.
  • the cover plate 6 is how FIG. 2 clarified, removable.
  • fastening means 13 preferably in the form of positive locking means, can be provided which can engage at different locations. For example, they can hold the cover plate 6 on the storage shelves 14, which can be inserted into the interior 7, cf. FIG. 1 ,
