<p>The ice cube tray has partitions determining the size of cubes. The walls of the tray (5) or the partition walls can be heated for short period for facilitating removal of the ice. A resistance heater system is used which is connected by an automatic switch to an electric power source. This switch is connected to a thermostat which ensures that heater can be connected only after ice cubes have been formed. The tray can be revolved about its axis in the refrigerator through half a circle for emptying.</p> |
