Abstract

A refrigerator-freezer combination with cyclic defrosting function by natural air circulation in the refrigerator comaprtment (11) and timed automatic defrosting operation and forced air circulation in the freezer compartment (12).
The combination permits any control on the user's part of the defrosting operation to be eliminated, this operation being carried out in an automatic manner in both compartments.
