DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows the tray 10 in accordance with the present invention in a first embodiment. The tray has a throughgoing surface. In the present embodiment, it is made of glass; but the use of other materials is also conceivable. It is also possible to make the tray as a grating.
The icemaker 20 is located directly beneath the tray 10 and is fastened to the tray 10 by means of a holder. This holder is made up in the embodiment in accordance with FIG. 1 of lugs 22 which engage around the rear side of the tray 10 and are made in one piece with the icemaker 20. As can be seen from FIG. 1 and in particular from the detailed representation in accordance with FIG. 3, the lugs 22 engage over the upper side of the tray 10. There is a groove 23 between the lugs 22 and a surface or edge of the icemaker 20 disposed beneath them and a section of the rear region of the tray 10 can be pushed into it, as can be seen, for example, from FIG. 3.
The icemaker 20 is furthermore secured in accordance with the embodiment of FIG. 1 via a holding part 40 which is made substantially in U shape in cross-section and whose limbs engage around the tray 10, on the one hand, and a part of the icemaker 20, on the other hand, as is shown, for example, in FIG. 1.
As can furthermore be seen from FIG. 1, the lateral edge regions of the tray 10 are each made with a holding rail 50, said holding rails being placed onto ribs 110 of the inner container 100 of a freezer, as can be seen from FIG. 5.
FIG. 2 shows an alternative embodiment of the tray 10 in accordance with the invention. In this case, the holder is likewise made up of the lugs 22 already described with respect to FIG. 1 and furthermore of a screw connection between the tray 10 and the icemaker 20. For this purpose, a screw 30 which fixes the icemaker 20 to the tray 10 is provided in the region of the tray 10 at the front in the direction of the user. The icemaker 20 is thus also fastened to the tray 10 at a plurality of positions in this embodiment.
As can be seen from FIGS. 1 and 2, the holder is made such that the icemaker is arranged suspended beneath the tray 10 or the glass plate, with it being held and positioned without additional fastening means in the rear region. The holder is there made up of the named lugs 22 which can form an integral component of the rear region of the icemaker 20. The positioning is likewise intrinsic at the front side. The fastening of the icemaker 20 takes place here by means of a screw 30 or by means of a clamp connection via a holding part 40 which carries out a multiple function in the present embodiment, as will be explained in more detail below.
As can be seen from FIG. 1, the holding part 40 is latched at the front to the icemaker 20 and to the tray 10 such that the icemaker 20 and the tray 10 are clamped to one another. Provision is preferably made in this respect that a dismantling of the icemaker 20 or of the holding part 40 is not possible without the aid of tools.
A reed contact 42 is located in the holding part 40, as can be seen from FIG. 4 which shows the holding part 40 from the inner side facing the icemaker 20. The reed contact 42 serves the drawer polling. It is known from the prior art to arrange the reed contact behind the cover in the icemaker itself. Provision is now made in accordance with this embodiment that the positioning of the reed contact 42 takes place outside the icemaker 20. The reed contact 42 communicates with an electronics board via a suitable signal line. Provision is made in this respect that the connection cable between the reed contact 42 and the electronics board is equipped with a releasable plug connection.
Such an embodiment of the invention does not only apply to the embodiment in accordance with FIG. 1, but also to that in accordance with FIG. 2. In this case, the reed contact is positioned via a similar plug connection in the front region of the icemaker 20. It can furthermore be recognized from FIG. 2 that the front region of the icemaker projects slightly over the lower side of the tray 10 so that it is also secured in a shape-matched manner by the front side of the icemaker 20.
As can be seen from FIG. 5, the tray 10 in accordance with the present invention can easily be arranged on a rib 110 of the inner container 100 of a freezer or of any other refrigerator unit and/or freezer unit. With a correspondingly variable arrangement of the water inflow, it is also possible to arrange the tray 10 at different positions in the unit. It can generally likewise be considered to arrange the icemaker 20 releasable from the tray 10 in order optionally to arrange it at another tray 10 provided that it allows the water inflow.
In any case, the icemaker position can be selected in the unit with low effort so that unit variants are optionally also possible with a different drawer division.
A protection against the unauthorized removal of the tray 10 with the icemaker 20 can be seen from FIGS. 6 and 7. In both cases, the tray 10 is secured against the removal from the receiving geometry in the inner container. Provision is preferably made in this respect that the removal of the securing arrangement and thus the removal of the tray 10 is not possible without tools.
FIG. 6 shows an embodiment in which the tray 10 is clamped to a section of the inner container. Provision is made for this purpose that a securing element 60 is inserted whose lower side lies in planar fashion on the tray 10 and which is received in an upper region in a cut-out 120 at the inner container. This securing element 60 is made such that it is pushed laterally into the corresponding cut-out 120 in the inner container 100. The securing element 60 has two regions which are at least partly plate-like and of which one (61) lies on the tray 10 and the other (62) contacts the cut-out. The two plate-like regions 61, 62 extend, for example, in parallel or substantially in parallel with the tray 10. They are connected to one another by a section 63 which extends perpendicular or at an angle to the tray 10 and is directed toward the inner space of the unit.
FIG. 7 shows an embodiment in which a securing element 70 is provided which does not act directly on the tray 10, but rather on the holding rail 50 which is connected to the tray 10. This securing element 70 is pushed in from the front between a rib 100 of the inner container 100 of the freezer and the holding rail 50 and can also be removed toward the front, preferably only while making use of tools.
FIG. 8 finally shows the embodiment of the water inflow 120. As can be seen from FIG. 8, the water inflow 120 takes place through the rear unit wall, that is no connection is necessary to the top or to the intermediate base, whereby new unit variants with different positions of the icemaker are made possible. The component shown in FIG. 8 can be made purely as a water inflow or also a combination part with a cable leadthrough. For the reception of the water inflow 120, a semicircular or partly circular cut-out 12 is provided in the rear region of the tray 10, said cut-out also being visible from FIGS. 1 to 3, with the lugs 22 partly projecting into it.
In the embodiment shown here, the inlet inflow angle is 20° and the material is polypropylene. Other angular embodiments and material embodiments are naturally also conceivable.
A special hook geometry in the middle tube part allows the application of an additional heating 130, as can be seen from FIG. 8.
The present invention enables a selectable space-saving position for the icemaker, for example in the middle region, or also at another position of a freezer. Depending on the requirement, its position can be moved downwardly or upwardly with respect to the variant in accordance with the drawer division.
The freezer can be made with drawers which are not shown in FIG. 5, which run directly on the tray 10, as is in particular the case in accordance with FIG. 2, or which can be pushed in and out via extensible rails which are formed by the holding rails 50 in accordance with FIG. 1 or are connected to them.
The reference symbol 32 in FIGS. 1 and 2 characterizes a nub which is molded to the icemaker 20 and engages into a bore in the tray 10.
The holder of the icemaker can be made as a one-part component with the icemaker and can, for example, form a part of the housing. It is likewise conceivable that the holder and the icemaker are formed by two components which are separate, but which are connected to one another.
