Description

[0028] Further details and advantages of the invention are explained in detail by means of an exemplary embodiment illustrated in the drawings.

[0029] The drawings show in:

[0030] FIG. 1: schematic variants of pulse generation,

[0031] FIG. 2: a first embodiment of the pulse generation means with storage container,

[0032] FIG. 3: a second embodiment of the pulse generation means with storage container,

[0033] FIG. 4: a third embodiment of the pulse generation means with storage container, and

[0034] FIG. 5: a perspective view of an ice cube manner with storage container.

[0035] In the exemplary embodiment described in the following, an ice cube maker 120 is arranged in the cooled interior space of the device in accordance with FIG. 5, which ice cube maker comprises an ice cube tray 100, into which the water to be frozen is filled, as well as a motor 110 for ejecting the ice cubes through a rotation of the ice cube tray 100. Reference character 130 relates to a filling level measuring device for determining the filling level of the ice cubes in the storage container 120 arranged below the ice cube maker 120, which is generally preferably configured as a drawer.

[0036] In order to prevent ice cubes in the storage container 120 from freezing together, or at least minimize this, according to the invention provision is made for a pulse generation means which is arranged and configured to apply one or multiple pulses to the storage container.

[0037] According to FIG. 1 (upper drawing), it is possible to apply a strong pulse, then not to apply a pulse over a time span, and subsequently optionally output another pulse, etc. In this illustration, the force acting on the storage contained is plotted against time.

[0038] According to another approach according to FIG. 1 (lower drawing), the introduction of multiple weaker pulses in the form of a vibration is conceivable. In this representation, the amplitude of the vibration is plotted against time.

[0039] FIG. 2 shows an exemplary embodiment with a motor 1, which generates a rotary movement around a rotary axis standing vertically with respect to the drawing plane. The motor 1 serves to rotate and twist the ice cube tray 100, whereby the ice cubes 30 fall into the storage container 20.

[0040] Reference character 10 generally relates to a means for building-up stress, which in this example is formed by the catch 11 and by a region of the storage container 20 that cooperates with the catch.

[0041] The catch 11, which rotates along with the motor, cooperates with the peripheral region 12 of the storage container 20, namely in such a way that the storage container is put into a stressed state by the rotation. The built-up of stress occurs until the point rotation till here=build-up of stress shown in FIG. 2. If the motor 1 is rotated further, contact between the catch 11 and the storage container ends abruptly, which causes the required pulse. The same applies if the catch is suddenly removed.

[0042] This release can occur with the rotation end of the ice cube tray 100, or prior to or after the ejection of the ice cubes into the storage container 20. The mentioned pulse can occur at every ejection, or at regular intervals, or after the filling level measuring device 130 registers that no ice cubes have been removed.

[0043] The likewise shown position rotation till here =ejection of ice cubes indicates the position of the motor where an ejection of the ice cubes from the ice cube tray 100 into the storage container 20 occurs.

[0044] FIG. 3 shows an exemplary embodiment, in which a wedge or another oblique plane 60 is arranged at the inner side of the door 50, which cooperates with the storage container 20 in such a way that the storage container is lifted when closing the door. This can occur through the door, or also through another moveable element, e.g. through a drawer neighboring the storage container 20, etc.

[0045] When opening the door, the storage container 20 falls back into its initial position, so that a corresponding pulse is generated.

[0046] FIG. 4 shows an embodiment, in which a spring mechanism is tensioned in multiple stages. It is thus conceivable that the spring mechanism, which can include one or multiple springs, is tensioned further in a stepwise manner, and the storage container is lifted thereby every time the door, or another closing element of the device, is opened or closed, or a drawer etc. is opened or closed. At a certain count, e.g. closing or opening the door etc. for the third time, the spring mechanism is relaxed abruptly, which results in that the storage container 20 falls back into its original position so that a pulse is triggered as well.
