Definitions

  • the present invention relates to a freezer, preferably a refrigerator and freezer with separate refrigerating and freezing parts, with a surrounded by a heat-insulating housing freezer in which at least one cold accumulator is storable.
  • cold accumulators in the form of mostly cuboid, filled with eutectic solution containers are regularly stored to freeze the eutectic solution of these cold accumulators.
  • the refrigerated batteries cooled down during the operating time of the freezer serve, on the one hand, to maintain the intended freezer compartment temperature even in the event of a power failure over a certain period of time, thus prolonging the freezing space in comparison with a freezer compartment not equipped with refrigeration batteries.
  • cold accumulators are used in a known manner in mobile coolers to cool drinks or foodstuffs transported therein.
  • a portable cooling container in which under the ceiling of the inner container, a support for cooling batteries can be fastened.
  • the said carrier can be inserted here like a drawer between L-shaped retaining profiles.
  • the font shows DE 199 07 184 A1 a freezer, in which above the drawers to hold the frozen food another, thin cold ticker drawer is provided, can be used in the cold batteries and positioned by inserting the drawer under the ceiling of the freezer compartment.
  • the present invention is based therefrom on the object to provide an improved freezer of the type mentioned, which avoids the disadvantages of the prior art and the latter further develops in an advantageous manner.
  • a space-saving arrangement of cold batteries is to be achieved, which does not affect the handling of the drawer-like pull-out of the freezer compartment container and their storage volume.
  • the cold batteries are therefore no longer attached to the container bottoms and no longer placed on a specially provided intermediate floor under the cold room ceiling. Rather, the cold batteries are hung directly under the freezer compartment ceiling.
  • holding means are provided in the ceiling region of the freezer, where the at least one cold accumulator under the ceiling hanging releasably fastened.
  • the at least one cold accumulator on one of its narrow sides on an elastically gurdrückbaren edge portion, wherein the holding means comprise a latching receptacle into which the respective cryogenic accumulator is snapping under deformation of the elastic edge portion.
  • the holding means may be provided on the ceiling and / or in the transitional area between the ceiling and the side or rear wall, to attach the cold battery to the ceiling hanging.
  • the freezer compartment available in the freezer housing can thereby be utilized in the best possible way.
  • the usable storage volume is increased.
  • the trays of drawer-like pull-out containers, freezer trays or even storage shelves without retaining projections or projections can be designed as flat surfaces on which the food to be frozen can be better turned off.
  • the available space can be better used, since the entire depth of the ceiling can be used for storage of a cold accumulator, as well as a deeper in the freezer compartment arranged cold accumulator is still tangible.
  • a receiving recess for receiving the at least one cold accumulator may be provided in a further development of the invention in the ceiling of the freezer compartment.
  • the insulation of the housing in the region of the receiving recess may be weakened relative to an adjacent ceiling section and / or the housing may have a reduced wall thickness in the region of the receiving recess relative to the surrounding ceiling section.
  • the insulation of the housing in the region of the receiving recess may be weakened relative to an adjacent ceiling section and / or the housing may have a reduced wall thickness in the region of the receiving recess relative to the surrounding ceiling section.
  • the receiving recess in the freezer compartment ceiling can basically be designed differently and arranged at different locations.
  • the receiving recess may be spaced from a front edge of the freezer compartment ceiling at the freezer compartment access opening, in particular recessed into the depth of the freezer compartment, so that the insulation of the housing on the said ceiling edge undergoes no weakening. This is cold technically favorable.
  • Refrigerant lines in the housing can be provided undisturbed in the area of the front edge of the ceiling.
  • cross-connection between the refrigerator and the freezer part does not need to be weakened, so that an insulation in the front region of the cross-connection is maintained.
  • the insulation can be weakened in the manner mentioned.
  • an additional usable freezer compartment volume is created behind the front edge of said cross-connection.
  • the retaining means for suspending the cold batteries on the freezer compartment ceiling can in principle be designed differently.
  • they comprise latching means, by means of which the cold batteries can be positively locked to the freezer compartment ceiling.
  • the holding means advantageously form an integral part of the top wall and / or the respective cold accumulators.
  • To fix the cold batteries advantageously no additional parts are provided, which would have to be attached to the freezer compartment ceiling, such as attachable or screw-in clips, clamps or the like.
  • the holding means are formed directly by a portion of the top wall and / or a portion of the cold-accumulator wall.
  • the cold batteries are held by the holding means at their front or narrow sides. Although it would in principle also be possible to attack the holding means on the large flat sides of the cold batteries. By a lateral holding on the narrow or end sides, however, a large-scale freezing can be prevented.
  • opposing end faces of a cold accumulator may have protruding positive locking means which can be inserted positively in opposite receiving recesses in the freezer compartment wall.
  • protruding positive locking means which can be inserted positively in opposite receiving recesses in the freezer compartment wall.
  • the at least one cold accumulator may have a carrying handle which forms the elastic edge section for latching the cold accumulator to the ceiling.
  • the carrying handle can form a slightly curved outwardly projecting strap, which is elastically pressed back when snapping.
  • positioning projections are provided on the cold accumulator on a side of the cold accumulator facing the ceiling and / or on the ceiling, by means of which the cold accumulator can be precisely positioned under the ceiling.
  • a defined positioning of the cold battery under the ceiling is possible even with a certain degree of icing.
  • a flat freezing of the cold accumulator is prevented.
  • the cold accumulator is advantageously formed symmetrically, so that it can be fastened in different reverse orientations to the holding means under the ceiling of the freezer compartment.
  • the cold accumulator has fastening means, in particular on opposite sides, and / or fastening means formed symmetrically with respect to a plane of symmetry of the cold accumulator, so that the cold accumulator can be engaged with the holding means on the freezer compartment wall, so to speak, without regard to the top and bottom sides.
  • the refrigerator and freezer 1 shown in the figures comprises an overhead cooling part 2 and a freezer 3 below, which can be closed by a refrigerator door 4 and a Gefrierteilt 5, which are hinged to each upright pivot axes laterally to the total cubic device body 6 , see.
  • FIG. 1
  • the device body 6 comprises an insulating housing 7, which comprises an approximately centrally arranged, horizontal transverse web 8, which separates the freezer compartment 9 from the cooling chamber 10, cf.
  • FIGS. 1 and 3
  • FIG. 1 shows, in the freezer compartment 9 a plurality of drawer-like pull-out container 11 for receiving frozen food are arranged one above the other.
  • a receiving recess 14 is provided for this purpose in the ceiling 12, in which the respective cold accumulator 13 can be used.
  • said receiving recess 14 is offset to the rear in the depth of the freezer compartment 9 and arranged spaced from the door 5 adjacent the front edge 15 of the ceiling 12.
  • the receiving recess 14 is adjacent to the rear wall 16, so that the cold accumulator is mounted on the rear, rear ceiling area.
  • the receiving recess 14 is about as deep as the cold accumulator 13 is thick, making the best possible compromise between the lowest possible weakening of the insulation and on the other hand lowest possible Nutzraumbeeintr structuredung is achieved by projecting the battery.
  • the transverse web 8 of the housing 7, which separates the cooling part 2 from the freezer part 3 is made thinner in the region of the receiving recess 14 than in a surrounding ceiling section.
  • the receiving recess 14 is not weakened in its isolation by the arrangement of the receiving recess 14, a front, the door 5 facing portion of the transverse web 8 and the freezer compartment ceiling, which has a favorable effect refrigeration technology.
  • holding means 17 are provided, which are an integral part of the freezer compartment ceiling 12 and the respective cold accumulator 13, ie no separate fastening parts are provided.
  • the holding means 17 are advantageously formed positively, in particular they form Verraststoff.
  • opposite edge legs 18 and 19 of the overall trough-shaped receiving recess 14 are slightly concave or they have a direction perpendicular to the plane of the ceiling 12 undercut latching recess. Concrete is how FIG.
  • corresponding latching surfaces are provided on the flat sides of the cold battery 13.
  • the trailing edge of the cold accumulator 13 is also tapered slightly wedge-shaped, see. FIG. 1 .
  • a carrying handle 20 is provided which convexly convexly outwardly Stirrup portion 21 has, which can snap fit into the concavity of the edge leg 19.
  • Said bracket portion 21 of the carrying handle 20 is elastically reinforceddrückbar to allow a snap.
  • the cold accumulator 13 needs only along the ceiling 12 along to be pushed to the rear wall 17 of the freezer compartment until it engages in the wedge-shaped recess on the edge legs 18.
  • FIG. 2 shows, the cold accumulator 13 formed symmetrically.
  • both the wedge-shaped chamfer at the trailing edge of the cold accumulator 13 and the convexly outwardly curved stirrup portion 21 are formed symmetrically to the two longitudinal center planes of the chill battery 13, so that the chill battery 13 can be inserted with both flat sides upwardly into the exception well 14. This greatly simplifies handling of the cold batteries 13.
  • nub or truncated positioning projections can be provided, which are in the fixed position in the receiving recess 14 on the ceiling 12, see. FIG. 1 , Alternatively or additionally, the cold accumulator may have positioning recesses.
  • refrigerant pipes 23 are advantageously guided directly over the receiving recess 14, as FIG. 1 shows. In addition, the refrigerant pipes 23 are also guided over the front edge portion of the ceiling 12, which faces the door 5.
