Refrigeration appliance having a siphon in the condensate drain

Abstract

A refrigeration appliance, particularly a domestic refrigeration appliance, has an inner chamber surrounded by a thermal barrier coating, an evaporator which cools the inner chamber, and a condensate drain which leads into the open from the evaporator through the thermal barrier coating. The condensate drain includes a siphon, which is arranged on the inner side of the thermal barrier coating and which is heatable by a defrost heater.
