Abstract
An ice maker module is built on an integrally formed plastic base. One or more ice making modules are stacked on top of an ice bin. Integrally formed within the plastic base is 'wet' compartment within which are disposed multiple numbers of evaporators on which water is frozen into ice cubes. The plastic base also separates the wet compartment from a dry compartment in which is mounted refrigeration components and control circuitry. The evaporators are constructed of two plates of stainless steel. Icing sites are located on the flattened sides of a serpentine refrigeration channel formed between depressions in the stainless steel plates. A microcontroller operates the ice making process. Harvesting of the ice cubes is initiated after the ice maker has used an amount of water necessary to make the ice. An ultrasonic range finder monitors the amount of ice in the bin.
