Definitions

  • the present invention relates to a refrigerator unit and/or a freezer unit having a unit carcass with one inner wall behind which a cooling element of the refrigerator circuit is arranged for the refrigerating of the inner space as well as with a cover plate disposed as a screen in front of the inner wall of the unit carcass in the inner space of the unit carcass.
  • the cover plate is held in the inner space by releasable fastening means and can be removed from the inner space so that the inner space is selectively usable with or without the cover plate.
  • the unit is hereby given a variable inner space volume which can be enlarged as required by removal of the cover plate to provide the maximum possible storage space. The problem of the condensate formation and frost formation on the inner carcass wall can be eliminated, on the one hand, by this variable inner space concept, and the maximum possible cubic capacity can nevertheless be provided as required.
  • the refrigerator unit and/or freezer unit has a control device which takes account of the technical refrigerating effects of the removal or insertion of the cover plate.
  • the control device can change at least one operating parameter of at least one unit component with a technical refrigerating effect in dependence on whether the cover plate is inserted in the inner space or has been removed from it.
  • the control device adapts the operation of the necessary unit components to the presence or absence of the cover plate.
  • the control device can preferably change a temperature switching value of the cooling unit when the cover plate is removed from the inner space.
  • control device can change the operating mode of a fan which is provided in the inner space of the unit.
  • a fan is arranged such that an air circulation takes place in the gap which is provided between the inner wall of the unit carcass and the cover plate disposed in front as a screen.
  • the fan can, for example, be arranged in the region of the upper end of the cover plate and/or below a top side of the inner space such that the air circulation effected by the fan sweeps past behind and/or in front of the cover plate.
  • the control device can in this respect change the operating mode of the fan differently depending on its built-in situation. If the fan is fixedly mounted in the inner space, the switching times or operating intervals can be changed by the control device depending on whether the cover plate is inserted or has been removed.
  • the fan can also be mounted on the cover plate itself so that it can be removed together with the cover plate.
  • the control device can simply deactivate the fan control routine when the cover plate has been removed.
  • a detection device can be provided which detects whether the cover plate is inserted or has been removed.
  • the control device changes the named at least one operating parameter of at least one unit component with a technical refrigerating effect in dependence on a signal of the detection device.
  • the detection device can generally have different designs.
  • the detection device works in contact-free manner.
  • a reed switch can in particular be provided which detects the presence of the cover plate in the inner space.
  • the releasable fastening means for the cover plate can generally have different designs.
  • the fastening means can advantageously be releasable or, conversely, closable or fastenable by hand in tool-free manner.
  • the fastening means can in particular hold the cover plate at the desired position in front of the inner wall to be covered in the inner space in a shape matched and/or force transmitting manner.
  • a fastening which is particularly simple to operate and is nevertheless stable is provided by latch means by which the cover plate can be latched at the desired position in the inner space.
  • the fastening means can generally be provided at different points in this respect. They can in particular be provided at the unit carcass and/or at the cover plate itself. Alternatively or additionally, fastening means can also be provided on storage trays and/or can be provided to cooperate therewith on the cover plate so that the cover plate can be fastened to storage trays or compartment bottoms which can be inserted into the inner space of the unit carcass.
  • receiving recesses can be provided at the unit carcass into which the cover plate can be inserted.
  • fastening projections in particular fastening ribs, can also be provided at the unit carcass and the cover plate is held at them in a shape matched manner.
  • One side of the cover plate can advantageously be inserted into a receiving recess and the oppositely disposed side can be latched with latch means provided there. Provision can be made in this respect to slide in the cover plate at the bottom and to latch it at the top or, alternatively, to slide it in at the top and to latch it at the bottom. Alternatively to this, the cover plate can also be slid in at the side and latched at the side as well, but opposite thereto.
  • the cover plate itself can generally have different designs. It can be made as a simple glass plate, plastic plate or metal plate, but also as a plate having at least one insulation layer made of polystyrene and/or PUR. If the dividing plate is made of glass, in addition to simple glass, safety glass or mirror glass can also be used, whereby special design effects are possible.
  • the cover plate can be made in different sizes in this respect. In a further development of the invention, it is made at least so large that it covers the region of the inner wall behind which the evaporator of the refrigerator circuit is disposed. In this connection, the cover plate can in particular be arranged aligned substantially vertically in front of the rear wall of the unit carcass.
  • the cover plate does not necessarily have to be planar in the sense of a mathematical plane in this respect, but can rather also comprise elevated portions and/or have curved portions.
  • FIG. 1 a schematic sectional representation of the unit carcass of a refrigerator unit in accordance with an embodiment of the invention, with the cover plate being shown in the inserted state;
  • FIG. 2 a schematic sectional view of the unit carcass of FIG. 1 , with the cover plate being shown in a dismantled state while being removed.
  • the refrigerator unit 1 shown in the Figures has a substantially cubic unit carcass 2 whose housing is insulating in the usual manner.
  • an evaporator 4 of the refrigerator circuit is provided at the rear 3 of the unit carcass 2 and can be foamed into the insulation of the unit carcass 2 so that it comes to lie behind the rear inner wall 5 of the unit carcass 2 .
  • a cover plate 6 is disposed as a screen in front of the named rear wall 5 of the unit carcass 2 and is arranged standing upright in front of the named rear wall 5 in the inner space 7 of the unit carcass 2 .
  • the cover plate 6 is arranged substantially parallel to the rear wall 5 , but spaced apart from it so that an air circulation passage 8 is formed between the rear wall 5 and the cover plate 6 .
  • the cover plate 6 is arranged suspended, i.e. in the drawn embodiment its lower edge does not contact the base of the unit carcass 2 .
  • the gap 10 remains between the base 9 of the unit carcass 2 and the cover plate 6 , cf. FIG. 1 .
  • a fan 12 is arranged at the top side 11 of the unit carcass 2 at the rear end of the inner space 7 and an air circulation can be achieved around the cover plate 6 by means of said fan, with the named air circulation passage 8 also being ventilated between the cover plate 6 and the rear wall 5 .
  • the cover plate 6 can be removed, as FIG. 2 illustrates.
  • fastening means 13 can be provided, preferably in the form of shape matched latch means, which can engage at different points. For example, they can hold the cover plate 6 at the storage trays 14 which can be inserted into the inner space 7 , cf. FIG. 1 .
