An ice cube dispensing unit comprising a housing suitable for containing at least two ice cubes, and a dispensing mechanism arranged at one end of the housing. The dispensing mechanism comprises an opening which is large enough for the ice cubes to pass through, a wall arranged near an edge of the opening, and an ice cube displacing mechanism suitable for displacing the ice cubes out of the housing through said opening. The ice cube displacing mechanism and the wall are arranged such that the ice cubes pass between the wall and the ice cube displacing mechanism on their way out of the housing. The ice cube displacing mechanism is arranged at a distance from the wall such that the minimum distance A between the wall and an outer periphery of the ice cube displacing mechanism is less than the minimum dimension of the ice cubes and either the wall and/or the outer periphery of the ice cube displacing mechanism is displaceable to allow the distance A to increase to allow ice cubes to leave the housing. An invention related to ejecting ice cubes from an ice cube tray and an invention related to filling an ice cube tray with liquid are also disclosed.
