Definitions

• the invention relates to a freezer or fridge / freezer combination with a freezer compartment in which an ice cube compartment is arranged, which has an ice cube maker and a trough-shaped ice cube drawer.
• freezer or fridge-freezer combination devices are known from the prior art, reference being made, for example, to DE 10 2017 001 011 A1.
• the freezer compartments of such devices often also include several storage drawers for storing frozen goods.
• the drawers are usually arranged one above the other in the freezer compartment.
• a uniform height of the drawers is desirable, as can be seen, for example, in FIG. 1, the ice cube drawer 120 and all storage drawers 105 having the same height.
• the ice cube drawer 120 here extends only over half the width of the freezer compartment and shares one level of the freezer compartment with a storage drawer 105 which extends over the other half of the width of the freezer compartment.
• the heights to be regarded as optimal for storage drawers 105 are, however, often too low for the ice cube drawer 120, since the ice cube maker already occupies a not insignificant part of the drawer height and the Pile ice cubes locally under the ice cube maker.
• This state of affairs is illustrated in FIG. 2, wherein it can be seen that the ice cube maker 150 protrudes into the drawer 120 from above and essentially occupies the entire upper half of the available volume of the drawer 120. Underneath, due to the continuous ice production, a heap of ice cubes 170 is formed, which initially is not distributed over the entire base area of the drawer 120. In this way, the maximum filling level below the ice cube maker 150, which can be detected, for example, using a lever 180, is reached early, often already after the production of little ice.
• the idea was to double or increase the height of the ice cube drawer. This would then occupy exactly two levels of the freezer compartment and the basic division of the freezer compartment would be maintained.
• FIG. 3 the ice cube drawer 120, which is doubled in height, in turn only extending over half the width of the freezer compartment and dividing two levels of the freezer compartment with two storage drawers 105 arranged one above the other, half the width. This leads to a very high ice cube drawer 120 with a large storage volume, which would at most be suitable for users with a very high ice consumption, but would be too large for most applications
• the object of the invention is to propose an advantageous design of the ice cube drawer which overcomes the disadvantages identified above.
• the invention relates to a freezer or refrigerator / freezer combination
• a freezer compartment with an ice cube compartment which has an ice cube maker and a trough-shaped ice cube drawer for collecting the ice cubes
• the ice cube drawer being constructed in two parts and comprising a main drawer and a secondary drawer
• the front panel of the main drawer has an insertion opening and the secondary drawer is inserted into the main drawer through this insertion opening.
• Both the main drawer and the secondary drawer are preferably trough-shaped and have a bottom, two side walls, a rear wall and a front plate.
• the main drawer and the secondary drawer preferably have the same depth, so that the secondary drawer, when fully inserted, extends to the rear wall of the main drawer and the bottom of the secondary drawer completely covers the bottom of the main drawer.
• the secondary drawer could also be designed without side walls and / or without a rear wall.
• the ice cubes are preferably removed primarily via the main drawer.
• the ice cube maker is preferably arranged on a ceiling of the ice cube compartment.
• An exemplary construction is shown in DE 10 2017 001 011 A1.
• the secondary drawer can lie on the bottom of the main drawer in a pull-out manner.
• At least one pair and preferably a plurality of pairs of guides for the secondary drawer lying one above the other can be provided on the side walls of the main drawer.
• the guide pair (s) make it possible to insert the secondary drawer into the main drawer at different heights.
• the ice storage volume can be individually determined by the user.
• the space between the floors of the main and secondary drawer, depending on the height of use, can be used to store other goods.
• the guides can be support ridges that protrude inwards from the side walls of the main drawer.
• the bottom of the secondary drawer can be placed on such webs.
• the dimensions of the front plate of the secondary drawer correspond to the dimensions of the insertion opening.
• the front of the ice cube drawer can therefore be composed of a total of two front panels, namely partly formed by the front panel of the flaup drawer and partially by the front panel of the secondary drawer.
• the front panel of the secondary drawer can, for example, occupy half the fleas of the drawer front, which makes it possible to give the ice cube drawer the appearance of two half-flea drawers.
• both the front panel of the main drawer and the front panel of the secondary drawer have a handle contour which may be identical or similar.
• the insertion opening can start directly at the bottom of the flaup drawer.
• the insertion opening is spaced from the bottom of the flaup drawer and a parapet is provided which extends from the bottom of the flaup drawer to the lower edge of the insertion opening.
• the parapet can prevent goods from falling out of the space between the floors of the flaup and the secondary drawer when the secondary drawer is in the raised position.
• the ice cube drawer comprises a closing plate which is held so that it is reversible in the plane of the front plates between an open position in which it opens the insertion opening and a closed position in which it opens the insertion opening covered, can be moved. It can be provided that the closing plate lies in the open position behind the front plate of the flaup drawer and can be reversibly shifted downwards from the opened position into the closed position. This enables the user to completely remove the secondary drawer in order to have a large-volume ice cube drawer permanently available.
• the ice cube drawer extends only over a portion of the width of the freezer compartment. It can therefore be provided that the ice cube drawer only extends over one part, for example half the width of the freezer compartment, and one level of the freezer compartment is shared with a storage drawer which extends over the other part, for example the other half of the width of the freezer compartment.
• additional storage drawers for storing frozen goods are provided in the freezer compartment below and / or above the ice cube drawer, the heights of the storage drawers preferably corresponding to an integer fraction and more preferably half the height of the ice cube drawer.
• the height of the ice cube drawer, measured by the height of the drawer front, would then take up an exact number, for example two levels, of the freezer compartment and the basic division of the freezer compartment could be maintained.

• FIGS. 4a-d show several sectional views of a first embodiment of an ice cube compartment 10 according to the invention, which includes an ice cube drawer 20 and an ice cube maker 50.
• the ice cube maker 50 is arranged on the underside of an upper shelf 11 which delimits the ice cube compartment 10 on the top. From there it protrudes into the interior of the ice cube drawer 20.
• the ice cube maker 50 comprises a cuboid module housing 51, in which an ice cube tray 52 which is rotatably mounted about a horizontal axis and an electric motor 53 for accommodating its rotation are received.
• the module housing 51 is open at the top and at the bottom so that water from a supply line 54 can get into the ice cube tray 52 from above and that finished ice cubes can get down from the ice cube tray 52 into the ice cube drawer 20 arranged under the ice cube maker 50 ,
• the side walls of the module housing 51 are also open, so that the exchange of air between the interior of the module housing 51 and the surroundings is promoted, which permits improved heat exchange and promotes freezing of the ice cubes.
• the ice cube drawer 20 is pushed into the freezer compartment of a device according to the invention. It is built in two parts and includes a main drawer 30 and a secondary drawer 40 which is pushed into the main drawer 30.
• the main drawer 30 is trough-shaped and has a bottom 31, two side walls 32, a rear wall 33 and a front plate 34.
• the front plate 34 and the side walls 32 extend over the full height of the main drawer 30.
• the rear wall 33 is designed to be somewhat lower, so that it can be pulled under the ice cube maker 50 when the main drawer 30 is pulled out.
• the side walls 33 are guided on the inside of the device or on a suitable intermediate wall of the device by means of guides, not shown, so that the main drawer 30 can be pulled out overall in the depth direction of the device.
• a handle contour 35 is provided, in which a user can reach to pull out the drawer.
• the ice cube compartment 10 can be delimited by a lower shelf that is not shown in the figures.
• the main drawer 30 can lie alternatively or additionally for attachment to lateral guides with its bottom 31 on such a lower shelf.
• the secondary drawer 40 is pushed into this insertion opening 36 from the front.
• the secondary drawer 40 is also trough-shaped and also has a bottom 41, two side walls 42, a rear wall 43 and a front plate 44.
• the front plate 44 is designed to be significantly higher than the side walls 42 and the rear wall 43.
• the secondary drawer 40 has the same or a depth that is only one wall thickness less and the same or one wall wall thickness smaller than the main drawer 30, so that it extends in the fully inserted state to the rear wall 33 of the main drawer and the bottom 41 of the secondary drawer 40 completely covers the bottom 31 of the main drawer 30.
• the front plate 44 of the secondary drawer 40 is dimensioned such that it fits exactly into the insertion opening 36 in the front plate 34 of the main drawer 30.
• a total of three circumferential sets of support strips 38 are provided, on which the secondary drawer 40 can be placed with its base 41.
• the vertical distance between the adjacent strips corresponds approximately to the height of the side walls 42 and the rear wall 43 of the secondary drawer 40, so that a guide for the secondary drawer 40 is formed by enclosing the side walls 42 between adjacent sets of support strips 38.
• the sets of support strips 38 are all arranged in that vertical region of the main drawer 30 over which the insertion opening 36 extends.
• the secondary drawer can be inserted into the main drawer 30 at different height positions, as can be seen from the illustrations in FIGS. 4a-c.
• FIGS. 5a-d show several sectional views of a further embodiment of an ice cube compartment 10 according to the invention, which is largely similar to the ice cube compartment shown in FIGS. 4a-d.
• a significant difference lies in a missing parapet 37, as a result of which the insertion opening 36 in this embodiment extends from the bottom 31 of the main drawer 30 to approximately the middle of the front plate 34 of the main drawer 30 and is thus somewhat higher than in the embodiment according to FIGS. d.
• the front plate 44 of the secondary drawer 40 is somewhat higher in this embodiment than in the embodiment according to FIGS. 4a-d.
• the lowest insertion position of the secondary drawer 30 is thus formed by resting the secondary drawer 40 on the bottom 31 of the main drawer.
• the sets of support strips 38 and their positioning remain unchanged, so that ultimately there is an additional insertion position of the secondary drawer.
• a locking plate 39 is missing in this embodiment, so that the main drawer 30 cannot be used independently.
