Filed:

May 4, 1990

Appl. No.:

7/518882

Inventors:

Marvin H. Josten - Garner IA
Robert P. Utter - Mason City IA
Kenneth W. Schneider - Mason City IA

Assignee:

The Cornelius Company - Anoka

International Classification:

F25B 3904

US Classification:

62126

Abstract:

A refrigeration control system having a temperature sensor responsive to condenser temperature. The sensor turns a condenser fan on and off in order to maintain the condenser temperature within pre-determined limits and also shuts down the refrigerant compressor in response to a predetermined maximum temperature.

Appl. No.:

7/501018

Inventors:

Robert P. Utter - Lake Villa IL

Assignee:

Scotsman Group, Inc. - Vernon Hills IL

International Classification:

F25C 500

US Classification:

2221466

Abstract:

An ice handling and beverage dispenser includes an agitator assembly mounted within a downwardly sloping ice storage bin, the assembly including a rotor connected to an agitator with the agitator comprising a frame to sweep the ice and the rotor having a plurality of circumferentially arranged L-shaped ice moving scoops. The agitator assembly is rotatably driven by a motor adjacent a front wall of the bin whereby ice is lifted by the scoops from a location adjacent the bottom of the bin to an outlet chute thereabove. When used in a beverage cooling dispenser, the sweep arm "sweeps" the bin wall whereby ice is caused to fall onto a cold plate disposed therebelow.

International Classification:

F25C 100

US Classification:

62 73

Abstract:

A method and apparatus for making ice wherein an ice cube maker has a generally upright gridded evaporator, a hot gas defrost for harvest of cubes, a storage bin below the evaporator, a hinged cube and water curtain between the evaporator and the bin, a new and improved control for the freeze cycle, and a new and improved control for the harvest cycle. The freeze cycle control has a temperature sensor, on a backside of the evaporator, circuitry to count down a predetermined time after a predetermined plate temperature has been sensed, the circuit terminates the countdown if the plate temperature exceeds the predetermined temperature and restarts the countdown when the predetermined temperature is again reached, and the circuit switches the refrigeration from freeze to hot gas defrost when the countdown is completed for harvest of the ice cubes; the harvest control has an ice curtain sensor connected to the refrigeration control, and a lever between the ice curtain and the sensor, when the curtain is opened by ice cubes the sensor picks up the lever movement and the control switches the refrigeration from the defrost to the freeze cycle.
