Ice maker with a heater and an ice tray made of heat-conductive plastic, and household cooling appliance

Abstract

An ice maker for a household cooling appliance includes an ice tray with cavities for ice form elements, a heater for heating the ice tray so as to enable incipient melting of the ice form elements in the cavities. The ice tray is made of a heat-conductive plastic. There is also described a household cooling appliance.
