An ice making device includes an ice tray, an ice separating mechanism which is a mechanism structured to take out ice pieces from the ice tray, a drive part structured to drive the ice separating mechanism, and a frame which supports the ice tray and the drive part. The frame is provided with a water passage part which guides water supplied from an outside to the ice tray, and the frame is attached with a water supply adaptor which is a water passage member separately provided from the water passage part for supplying the water to the water passage part.

An ice maker includes: an upper assembly comprising a plurality of upper chambers recessed upward to define an upper portion of an ice chamber in which water is filled and ice is made, and having an intake opening by being open on a top, and a vertical extension part formed to protrude upward around the intake opening; a lower assembly comprising a plurality of lower chambers recessed downward to define a lower portion of the ice chamber, and rotatably connected to the upper assembly; and a water supply part that is recessed downward from an upper side of the water supply part and configured to receive therein water for making ice, the water supply part being removably coupled to the vertical extension part and configured to guide the received water into the intake opening.

An ice machine includes: an ice maker including: an ultrasonic bin sensor mounted to a body; and a controller in electrical communication with the ultrasonic bin sensor and configured to control the ultrasonic bin sensor; and a storage bin coupled to the ice maker and sized to receive a mound of ice, a lens of the ultrasonic bin sensor facing a bottom of an interior cavity of the storage bin, the controller configured to process a return signal of the ultrasonic bin sensor to control a level of ice stored inside the storage bin, the controller further configured to apply a predetermined time delay to filter out a portion of the return signal that exceeds a threshold voltage but does not exceed the time delay.

Provided is an ice-making device that can autonomously perform a series of ice-making operations that include control of a fan motor, without relying on a higher-level device. An ice-making device that is characterized by comprising an ice-making tray, a fan motor that blows air onto the ice-making tray, an ice removal mechanism that removes ice from the ice-making tray, a control part, and a frame that holds the ice-making tray, the fan motor, the ice removal mechanism, and the control part. The ice-making device is also characterized in that the control part controls the operations of the fan motor, the ice removal mechanism, and a water supply mechanism that opens/closes a water supply path that supplies water to the ice-making tray.

A refrigerator appliance may include a cabinet, a liner, a sealed system, a conductive ice mold, a thermoelectric heat exchanger, and a water dispenser. The liner may be attached to the cabinet and define an icebox (TB) compartment. The sealed system may include a compressor to motivate refrigerant through the sealed system, and an evaporator disposed along an air path in fluid communication with the compressor to exchange refrigerant therewith. The conductive ice mold may be mounted within the IB compartment. The conductive ice mold may define a mold cavity along the air path to receive a chilled airflow from the evaporator. The thermoelectric heat exchanger (TEHE) may be disposed on the conductive ice mold to draw heat therefrom. The water dispenser may be positioned below the ice mold to direct an ice-building spray of water to the mold cavity.

A batch ice maker can execute a pulsed fill routine in which a control system pulses water from a water supply into the sump until the sump reaches a predefined freeze routine starting level. Pulsing may begin after continuously filling the sump to a fill-approach level. A batch ice maker can execute a differential freeze routine in which the control system circulates water from a sump to an ice formation device until water level decreases by a predefined differential amount from a high control water level based on the water level in the sump at a point in time after the sump was filled to a freeze routine starting level. The high control water level can be set based on water level in the sump when sump water temperature reaches a predefined pre-chill temperature. The predefined pre-chill temperature can be associated with a switchover from sensible cooling to latent cooling.

An ice maker apparatus includes an ice mold having first and second ends spaced apart in a longitudinal direction of the ice mold via opposite, first and second lateral sides. A first recess is formed in the first lateral side of the ice mold. A first thermally insulative cover has a first depression formed therein and is removably attached to the ice mold and disposed adjacent to the first lateral side thereof. The first recess and the first depression collectively define a first passage therebetween. An ice maker evaporator is provided and has a first leg. The first leg is disposed within the first passage.
