  • Patent number: 10907873
    Abstract: An ice maker includes an ice tray, a motor configured to rotate with respect to the ice tray, an ejector configured to cause rotation of an ice piece, the ejector including a rotary shaft and a protrusion pin, a heater configured to selectively supply heat to the ice tray, and a first sensor unit configured to detect a rotation angle of the protrusion pin about an axis of the rotary shaft. The first sensor unit is further configured to, before discharge of the ice piece from the ice tray, detect whether the protrusion pin has rotated by a predetermined angle about the axis of the rotary shaft, and the heater is further configured to be turned off based on the first sensor unit detecting that the protrusion pin has rotated by the predetermined angle.

  • Patent number: 10890368
    Abstract: An ice maker for forming ice having a refrigeration system, a water system and a controller. The refrigeration system includes a freeze plate in which ice is formed and a hot gas valve for harvesting the ice therefrom. A harvest sensor is triggered when at least a portion of the ice is harvested from the freeze plate and at least one temperature sensor measures a temperature that indicates that all of the ice has been harvested from the freeze plate. The temperature sensors may include a temperature sensor for measuring the refrigerant temperature at the evaporator outlet, the refrigerant temperature at the evaporator inlet, and/or the temperature of the freeze plate. The controller closes the hot gas valve in response from the triggering of the harvest sensor and the temperature measured by the temperature sensor(s) indicating that all of the ice has been harvested from the freeze plate.

  • Patent number: 9032745
    Abstract: A refrigerator includes a sensing system for detecting multiple physical characteristics of ice cubes in an ice cube storage bin. The system includes a digital image capture device coupled to a digital image analyzing system which captures digital images of the ice cube storage bin intermittently and compares the images to detect the presence of ice clumps. In addition, the digital image analyzing system evaluates the edges, ice size and/or image intensity of the ice cubes in the images in order to determine the presence of stale ice. An algorithm is utilized to estimate the volume of ice within the bin based on the number of pixels in an ice bin image, the number of pixels of the ice within the bin, and a known volume of the ice bin. Notifications for clumped ice, stale ice and ice volume within the bin are sent to a user interface.

  • Publication number: 20140208786
    Abstract: To defrost one barrel of a two barrel FCB dispenser, a refrigeration system defrosts the one barrel, while neither defrosting nor chilling the other barrel, for either a selected time or until a frozen beverage is drawn from the other barrel, whichever occurs first. Once the selected time or beverage draw occurs, the refrigeration system chills the other barrel until beverage within it is properly frozen, while neither defrosting nor chilling the one barrel. Once beverage in the other barrel is properly frozen, the refrigeration system resumes defrosting the one barrel, whereupon the foregoing cycle is repeated until defrost of the one barrel is complete, at which point the refrigeration system chills the one barrel to refreeze product in it. The arrangement keeps beverage in the other barrel properly frozen during defrosting of the one barrel.
