  • Cooling and / or freezing devices are known from the prior art, in which the condenser is arranged such that at least line sections of the condenser run through the condensate located in the evaporation tray.
  • the arrangement of the condenser in the evaporation tray has the advantage that the waste heat of the condenser can be used to evaporate the condensation.
  • DE 10 2006 061084 A1 relates to a condenser assembly for a refrigerator with a arranged on a support, can be traversed by a refrigerant condenser, wherein the carrier has at least one arranged above the condenser and arranged under the condenser evaporation tray
  • KR 2001 0073765 A relates to a capacitor mounting device for refrigerator.
  • JP 2001 133129 A discloses that a compressor and a water-cooled condenser are disposed on the opposite sides of the fan motor in the engine room.
  • US 5,966,958 A discloses a capacitor well for the capacitor assembly wherein the coils are protected from corrosion by the capacitor.
  • EP 2 136 168 A1 discloses a cooling device with a cooling system consisting of a compressor and a condenser, wherein an evaporation tray is arranged above the first condenser part of the condenser.
  • the present invention has the object of developing a refrigerator and / or freezer of the type mentioned in that can be dispensed with such a corrosion protection of the condenser and yet efficient heat transfer from the condenser to the evaporation tray or to the condensate therein is possible ,
  • This object is achieved by a refrigerator and / or freezer with the features of claim 1.
  • a refrigerator and / or freezer with the features of claim 1.
  • in or on the evaporation tray one or more receptacles for the condenser or are provided, wherein the at least one receptacle is arranged such that the condensate located in the evaporation tray is not in contact with the condenser.
  • the at least one receptacle for the at least one condenser is thus arranged such that the condenser is not arranged in the region which is filled with condensed water during operation of the device.
  • the condenser is not arranged in the region which is filled with condensed water during operation of the device.
  • the receptacle is thus preferably arranged in such a way that it communicates with the condenser on the one hand and with the condensed water on the other hand so that the heat released by the condenser is at least partially supplied to the condensed water through the receptacle, thereby promoting its evaporation ,
  • the evaporation tray has a bottom, the receptacle being in the form of one or more elevations or projections extending from the bottom of the evaporation tray.
  • the receptacle has a wall which partially or completely surrounds a cavity in which at least a portion of the condenser is located. It is also conceivable that the receptacle is designed as a compact body or has no cavity, in which the condenser is used. It is conceivable that the condenser is placed on the receptacle.
  • the wall may consist of a particularly good heat conducting material for the purpose of optimal heat conduction from the condenser in the condensate. It can be made thin, so that a good heat conduction takes place.
  • the condenser may be fixed positively and / or non-positively in said cavity.
  • the cavity corresponds in its contour substantially to the contour of the condenser.
  • the receptacle has a wall which has one or more ribs which are arranged in such a way that the ribs extend into the region of the evaporation cup in which the condensate water is located during operation of the apparatus. These ribs thus serve to optimize the heat conduction from the condenser in the condensate-filled area of the evaporation tray.
  • the evaporation tray has a bottom with the at least one rib extending to the bottom of the evaporation tray. If a plurality of ribs are provided, it is conceivable that they are arranged in the circumferential direction of the receptacle or spaced from the wall thereof.
  • the receptacle forms an integral part of the evaporation tray, resulting in a particularly simple manufacturability of the arrangement. It is conceivable, for example, the evaporation tray with the inclusion of a plastic part or a metal part, ie integrally form. In principle, it is also conceivable that the receptacle and the actual evaporation tray are two or more than two parts, which are joined together in the operating state.
  • the condenser may be, for example, a spiral condenser.
  • other condenser forms are conceivable. It is possible to carry out the spiral condenser such that a plurality of juxtaposed spirals are provided, which are each in an already mentioned recordings of the evaporation tray.
  • the invention is not limited in terms of the type and number of condenser. It is also conceivable to use only a spiral condenser or other condenser.
  • the one or more liquefiers of the recording is carried out detachably. In this way it is possible to remove the evaporation tray, for example for cleaning purposes.
  • the evaporation tray forms a first component of a module consisting of at least two parts, comprising at least a second component, the means for air guidance and / or means for guiding the condensed water and / or means for receiving a or comprising a plurality of components of the device and / or fastening means for fixing the module to the device.
  • the second component of the module may be, for example, a fan which conducts the air via the condenser or via the evaporation tray. It can also be provided that the component is the liquefier itself. For example, it is conceivable that the second component forms the upper receptacle for the condenser or condenser.
  • the condenser or its seals are realized.
  • the condensate inlet can be realized, through which the condensate runs into the evaporation tray.
  • said fan is removable, for example, for service purposes of the second component of the module.
  • the module may be, for example, a preassembled unit, which simplifies the production accordingly.
  • the refrigerator and / or freezer according to the invention is preferably an underbody device. It can be provided that said arrangement or said module is arranged in the base region of this device.
  • Reference numeral 10 represents a module that is manufactured in the form of a preassembled unit and then inserted into the base area of a sub-assembly.
  • the module 10 has a bottom arranged evaporation tray 12 and a second component 14, which fulfills various functions described in more detail below.
  • the two parts 12, 14 of the module 10 are designed to be detachable from each other.
  • the module 10 can thus be disassembled, for example, for cleaning or maintenance purposes.
  • the lower part, ie the evaporation tray 12 of the module 10 serves as a collecting tray for condensed water from the refrigerator. How this particular out FIG. 2 it can be seen extending from the bottom portion 13 of the evaporation tray 12 three adjacent receptacles 14, which have the shape of vertical hollow cylinder sections having ribs 16 on their outer walls. These receptacles 14 are integral components of the evaporation tray 12, that is integrally connected to the bottom 13 of the evaporation tray 12.
  • a spiral condenser 20 Inserted in the receptacles 14 is a spiral condenser 20, which in the exemplary embodiment shown here consists of three interconnected spiral-shaped regions 20a, 20b and 20c, each of which is in a receptacle 14.
  • the condenser 20 has conventional supply and discharge lines.
  • the condenser 20 as well as its supply and discharge lines are not arranged in the region of the evaporation tray 12, which is filled with condensed water during operation of the device. In this way it is possible to dispense with a comparatively complicated and expensive corrosion protection for the condenser 20 and its inlet and outlet pipes. At the same time the lower receptacle 14 of the condenser 20 also allows the removal of the evaporation tray 12 down for cleaning purposes.
  • the upper, second component 14 of the module 10 includes a receptacle not shown in detail for a fan and is used to guide air through the condenser 20 and via the evaporation tray 12 and an upper receptacle for the condenser 20.
  • the second component 14 of the module serves for air flow, surrounds the condenser 20 and sits as it were as a "lid" fully on the evaporation tray 12.
  • the second component 14 includes the condensation drain, as well as fastening means for fastening the module 10 in the device base and a recording of seals of the pipe penetrations of the condenser 20th
  • the advantages of the present invention are essentially that a cost advantage is achieved by eliminating corrosion protection coatings of the condenser that a space-saving arrangement of the condenser is possible that the Vertexerab Marvel can be used for condensate evaporation and that a dirt-insensitive geometry of the condenser used can be.
  • Another advantage of the arrangement is that there is good accessibility for the customer and that a removal of the fan, not shown, in the case of service is readily possible.
  • said maintenance or service steps are executable without tools.
