Ice making apparatus

Abstract

Ice making apparatus having one or more corrugated freezing plates with substantially vertical channels in which water flows to form ice cubes. Angled penetration lugs are secured to one surface of each freezing plate at vertically spaced intervals along the bent portions of the freezing plate defining the channels, and the refrigeration line is in contact with each of the penetration lugs so that ice cubes are formed evenly in vertically spaced relation along each of the channels defined by the bent portions of the freezing plate. The penetration lugs are bent at substantially the same angle as the bent portions of the freezing plate, and the lugs are bent or wrapped around the refrigeration line to maximize penetration. A thermostat is positioned at an angle adjacent one of the channels and near a cube to be formed that is below the uppermost cube. When the ice cubes reach a predetermined size, the thermostat is contacted by the adjacent cube and by the falling cube or cubes above it to close a circuit to a hot gas valve for the purpose of starting the defrost cycle and the ice harvest. The stacking of cubes in the channel against the thermostat serves to maximize the harvest cycle and insure the harvesting of all of the cubes on the freezing plates. A siphon device in the water reservoir periodically removes water therefrom to minimize impurities in the water.
