A stand-alone ice making appliance is provided. The stand-alone ice making appliance may include a container, a water tank, a pump, a reservoir, an ice maker, and a primary drain line. The container may define a first storage volume to receive ice. The water tank may define a second storage volume to receive water. The pump may be in fluid communication with the second storage volume to actively flow water from the water tank. The reservoir may define a third storage volume that is in fluid communication with the pump to receive water that is actively flowed from the water tank. The ice maker may be in fluid communication with the third storage volume to receive water from the reservoir. The primary drain line may be in downstream fluid communication with the second storage volume and bypass the reservoir to selectively drain water from the second storage volume.

An icemaker appliance includes a first reservoir, a second reservoir, a first circulation system associated with the first reservoir, and a second circulation system associated with the second reservoir. Liquid in the first reservoir is directed toward a first set of ice molds and liquid from the second reservoir is directed toward a second set of ice molds. Liquid in the first reservoir is selectively supplied to the second reservoir.

An icemaker appliance includes a cabinet forming an ice storage compartment, an ice maker provided in the ice storage compartment, a first reservoir storing liquid, a filter nested within the first reservoir, and a circulation system to deliver the liquid from the first reservoir to the ice maker. The liquid not frozen on the ice maker is filtered through the filter and resupplied to the circulation system.

A cryogenic fluid composition may include water (H20), and at least one salt. The ratio of water to the at least one salt is approximately between 1% and 6% salt with the remainder water. A cryogenic fluid production device may include a cylindrical housing, and a heat exchanger disposed within the cylindrical housing. The heat exchanger may include an inlet, a channel, and an outlet. A coolant may be conveyed through the inlet, the channel, and the outlet of the heat exchanger. The cryogenic fluid production device may further include an interior wall, and an auger disposed within the interior wall of the heat exchanger.

An ice making system includes an ice maker configured to form ice pieces therein with a top reservoir upstream of the ice maker and an ice bucket in communication with the ice maker. The ice making system also includes a recirculation tank and a recirculation pump. An oxidizing agent generator is configured to generate one or more oxidizing agents and provide the one or more oxidizing agents to form treated water within the ice making system.

Systems and methods are provided for dispensing ice and at least one liquid, and related cleaning processes. In one embodiment, the system comprises an ice bin for storing a quantity of ice particles, a dispensing tube for carrying at least a first liquid, and a discharge chute in communication with a discharge outlet, wherein the discharge chute is disposed upstream of the discharge outlet. An outlet end of the dispensing tube is positioned within a portion of the ice bin at a location aligned above the discharge outlet. The ice particles and the first liquid are dispensed through the discharge outlet separately or at the same time.

A lighting array including one or more antimicrobial light segments configured to emit light sufficient to inactivate one or more microorganisms at a target surface may be installed within identified contamination zones of food or beverage preparation, processing, storing or packaging equipment or machinery. In an ice machine, for example, an array controller is configured for communication with an ice machine controller to receive ice machine status information signals. The status information signals are usable by the array controller to determine cycle, state, and/or usage information associated with the ice machine. The array controller may individually control activation of the one or more antimicrobial light segments based on the status information signals received from the machine controller to achieve inactivation of one or more microorganisms on target surfaces within the machine.

A device for removing foreign matter in an ice maker is configured to prevent foreign matter from accumulating on the bottom of a float by changing the structure of the bottom of the float. The device includes a level sensor sensing a water level using a float moving up and down, depending on a height of water supplied in a water tank and a connection pipe forming a channel for water flow between the water pump and the level sensor by being connected to the level sensor, and having an inclined surface inclined downward toward an entrance of the channel under the float.

A household appliance includes an outer casing, a water tank and an ice maker. The water tank may be attached to the outer casing. The ice maker is disposed within the outer casing. The ice maker is in fluid communication with the water tank. The household appliance may further include a pump disposed within the outer casing, at least one drain tube attached to the outer casing and a controller. The pump may be in fluid communication with the water tank and the ice maker to flow water from the water tank to the ice maker. The at least one drain tube may define an exit point, the exit point located vertically below the ice mater. The controller may initiate a cleaning cycle that includes pumping a volume of cleaning solution through the ice maker and directing the volume of cleaning solution through the at least one drain tube.

An ice maker comprising a refrigeration system, a water system, and a control system. The control system includes a controller comprising a processor and a water level sensor. The water level sensor is adapted to externally sense a capacitance corresponding to a sump water level. The controller is adapted to control the operation of the refrigeration system and the operation of the water system based upon the sump water level and to detect one or more failure modes of the water system based upon the sump water level.
