Definitions
- the present invention relates to the field of refrigeration appliances.
- refrigerators can be used with automatic ice cube makers equipped with dispensers for whole ice cubes and crushed or crushed ice. Basically, such refrigerators initially produce ice cubes, which are then issued or further shredded and then spent. In addition, such refrigerators can also have a cooling space for receiving and cooling refrigerated goods.
- a fineness of the broken ice is given in the known devices.
- the ice cubes are crushed against knives for shredding, the fineness of the crushed ice depending on a distance of the blades to each other, which can not be changed after completion of the device.
- the fineness of the crushed ice can only be varied from device to device by installing the blades at different distances from each other.
- the crushed ice falls in the ice cube maker due to gravity through the blades in an output unit of the refrigerator. There, the crushed ice firm degree of fineness can be removed immediately, for example in a container for drinks. Furthermore, such
- Ice cube maker have a flap below the knife to prevent crushed ice and snow accidentally falls into the output unit due to gravity.
- the ice is then held in the area of the knives for at least a short period of time, so that the ice is comminuted differently.
- the finished crushed ice then has some non-controllable fineness.
- the invention relates in a first aspect, a refrigerator with an ice crusher for crushing ice and with an actuating element for activating the
- Ice crusher is configured to crush the ice for a period of actuation of the operating member. In other words, the ice is crushed as long as the actuator is actuated. Thus, a degree of comminution depends on the duration of actuation of the actuator. Under a refrigeration device is in particular a household refrigeration appliance understood, ie a
- Refrigeration appliance for housekeeping in households or possibly also in the household
- Catering area is used, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer or achengefrierkombination.
- Actuator ice different degrees of fineness produce. This makes it possible in a particularly simple way to produce crushed or broken ice, in particular with an almost arbitrary degree of fineness.
- the degree of fineness refers to an average grain size of the crushed ice. Furthermore, this may be the case with a refrigeration appliance having a flap for preventing accidental release of
- crushed ice has to be implemented without providing additional components.
- the ice crusher is designed to crush the ice only for the duration of the actuation of the actuating element. This ensures that the user has control over the fineness of the broken ice.
- the ice crusher is configured to crush the ice during actuation of the actuator for a presettable period of time. This makes it possible in a particularly simple manner to produce ice with a certain degree of fineness, since with a comminution of the ice for a fixed, preset period of time, the ice always has the same or almost the same degree of fineness.
- the refrigeration device has an adjusting element for setting the presettable period of time. This makes it easy to set the presettable time duration. The adjustment may, for example, a switch, a button, a push button, a rotary switch, a screen or a
- the adjustment element is provided to select a first presettable time duration in a first position and a second presettable time duration in a second position.
- a preset period of time is selected depending on the position of the setting member. This makes it easy to set the presettable time duration.
- Time duration can be determined empirically, for example, and / or on one
- Storage medium of a control unit of the refrigeration device to be stored
- the first position corresponds to a first degree of fineness and the second position corresponds to a second degree of fineness. This contributes to a certain degree of fineness being easily selectable.
- an average grain size of the ice is greater in the first degree of fineness than in the second degree of fineness. This contributes in a simple way that ice of different fineness and different average grain sizes is selectable.
- a degree of fineness of the crushed ice depends on the duration of actuation of the actuating element.
- broken ice of different degrees of fineness can be easily generated. For example, if the actuating element is actuated briefly, roughly crushed ice is produced. With a longer operating time of the actuating element, however, a finer crushed ice is generated.
- the refrigeration device releases the crushed ice after the actuation of the actuating element has ended or after the presettable period of time has elapsed, in particular automatically. This can help to ensure that the crushed ice has the fineness desired by a user of the refrigeration appliance.
- the ice crusher has a flap for releasing the crushed ice. This makes it easy to dispense the crushed ice. Furthermore, the flap prevents premature dispensing of the
- the ice crusher is adapted to release the crushed ice upon completion of the actuation of the actuator or upon expiration of a presettable period of time which may be the aforesaid period of time and upon expiration of a predetermined overrun time, in particular automatically. This helps to ensure that the crushed ice is completely dispensed.
- the ice crusher has a plurality of knives which crush the ice during the period of time. This makes it easy to crush the ice.
- the refrigeration device has a release element, upon actuation of which the broken ice is released. This allows the ice to be crushed and then released.
- the invention relates in a second aspect to a method for crushing ice by means of the ice crusher, which is activated by actuation of the actuating element.
- the ice is made by means of the ice crusher for the duration of the operation of the
- Shredded actuating element This allows, by pressing the
- the ice is crushed only for the duration of actuation of the actuator. This can help to precisely specify the degree of fineness of the ice.
- the ice is pressed during actuation of the
- Crushed actuator for the presettable period of time. This can do this contribute to preventing the ice from being crushed finer than desired. Furthermore, this can contribute to the crushed ice having exactly the desired degree of fineness.
- the presettable period of time is determined by means of
- Adjustment element set This can help to be able to adjust the presettable period of time in a simple manner and / or precisely.
- the first presettable time period in the first position of the adjustment element and the second presettable time duration in the second position of the adjustment element are selected. This allows a simple way to preset different durations.
- the first degree of fineness is selected by setting the adjustment element in the first position and the second degree of fineness by adjusting the adjustment element to the second position. This allows a simple way to select or preset different degrees of fineness and thus different durations.
- crushed ice having the first average grain size is prepared at the first degree of fineness, and at the second degree of fineness, minced ice having the second average grain size smaller than the first average grain size is prepared. This allows a simple way to produce crushed ice different average grain sizes. According to one embodiment, the crushed ice is dispensed upon completion of the actuation of the actuator or upon expiration of the presettable period of time. This can help to ensure that the crushed ice has the desired fineness.
- the crushed ice is after completion of the actuation of the actuating element or after expiration of a presettable period of time, which may be the aforementioned period of time, and after expiry of the predetermined

- the degree of fineness is representative of an average grain size of the crushed ice.
- Setting element 8 can be adjusted. With the help of the release element 9, the flap 26 can be opened, so that the crushed ice is released.
- FIG. 3 shows a diagram of a method for producing the comminuted ice, in particular with the aid of the refrigeration device 1, wherein steps 101 to 104 can be processed one after the other.
- step 101 the actuating element 7 is actuated.
- step 102 as a result of the actuation of the actuating element 7, the ice in the space 15 is comminuted.
- step 103 it is checked whether the actuating element 7 is still being actuated and, if appropriate, the comminution process is continued.
- step 104 is executed as soon as the actuation of the actuating element 7 is completed and the actuating element 7 is thus no longer actuated.
- step 104 the flap 26 is opened and the crushed ice in the space 15 is released.
- both periods can be
- a degree of fineness which the crushed ice should have, can thus be set.
- the degree of fineness can be adjusted by selecting a degree of fineness presettable by means of the setting element 8.
- the presettable degree of fineness corresponds to a presettable period of time during which the ice is to be comminuted. In other words, the period of time for which the ice is to be comminuted is at least indirectly selected via the setting element 8. This can do that
- Adjustment 8 are brought into different positions. For example, in a first position of the adjusting element 8, the ice is comminuted for a first period of time and in a second position for a second period of time. Furthermore, the adjustment 8 can have more position options.
- the positions are, for example, representative of the fineness levels “coarse”, “fine” and / or "very fine”.
