ABSTRACT:
A vertical ice cube mold chilled by a refrigeration system has a water stream pumped into its open vertical face to build up ice cubes in the mold. A probe hangs over the open mold face at an adjustable spacing. When the mold fills with ice and the water stream contacts the probe, an electrical circuit is completed to cause a control to stop the water pump and heat the mold, thus harvesting the ice cubes. A timer restarts the icemaking cycle in case ice is not delivered for some reason. Casual water contact with the probe is prevented from tripping the control through the use of a simple integrator device.
