Automatic ice-sphere-making system for refrigerator appliance

An automatic spherical ice maker for a refrigerator appliance, comprising:

• an upper stationary ice mold having at least one ice cavity with a hemispherical shape, and a lower rotatable ice mold having at least one ice cavity with a hemispherical shape and corresponding to the ice cavity of the upper stationary ice mold, so that together the at least one ice cavity of the upper stationary ice mold and the at least one cavity of the lower rotatable ice mold form at least one spherical mold which is configured to produce at least one substantially spherical ice ball at a time,
• wherein the upper stationary ice mold has a first heating element and the lower rotatable ice mold has a second heating element, thereby to facilitate release of the at least one spherical ice ball from the at least one spherical mold.
