  • Patent number: 11098939
    Abstract: An ice maker for a domestic refrigeration appliance has an ice tray with at least one cavity for holding and freezing liquids to form a shaped ice element. An ejection unit ejects the shaped ice element from the cavity. A drive apparatus performs a relative rotational movement between the ice tray and the ejection unit to eject the shaped ice element from the cavity. The ice maker has a twisting apparatus that is coupled to the ice tray and that can be used to twist the ice tray around to release a frozen shaped ice element in the cavity. There is also described a domestic refrigeration appliance with the ice maker and a method for ejecting shaped ice elements from the ice tray.

  • Patent number: 10584907
    Abstract: A domestic refrigeration appliance includes an ice and/or water-dispensing device for non-crushed ice pieces or ice flakes created therefrom by crushing or water created in the appliance, depending on an operational setting of a medium creation facility. The dispensing device has a user-actuatable dispensing lever movable to start dispensing. An adjustment facility adjusts an operational setting of the creation facility. An input facility has user-actuated controls selecting a medium dispensing type before actuating the lever. A control unit adjusts the adjustment facility depending on a signal created by actuation of a control and associated medium dispensing type, before actuating the lever to change the operational setting of the creation facility if the creation facility coupled with the adjustment facility is positioned in an operational setting different from that required for the selected medium dispensing type. A method of operating the appliance is also provided.
