The present disclosure provides an ice making evaporator that combines the cubic shape of pan and partition evaporators with the central ice making of a pin evaporator to achieve an ice shape that is mostly cubic. Separation of the cooling ability of these two evaporator portions allows cube shaping during ice making cycle based on time, temperature, pressure, or other variables.

A refrigerator appliance may include a cabinet, a liner, a thermodynamic assembly, an air conduit, a heat pipe, a conductive ice mold, and a water dispenser. The liner may define an icebox (IB) compartment. air conduit may be disposed within the IB compartment. The air conduit may define a conduit path between a conduit inlet and a conduit outlet downstream from the conduit inlet. The heat pipe may be mounted to the air conduit and extend therefrom outside of the conduit path. The conductive ice mold may be mounted to the heat pipe within the IB compartment. The conductive ice mold may define a mold cavity outside of the air conduit. The water dispenser may be positioned below the conductive ice mold to direct an ice-building spray of water to the mold cavity

An icemaker appliance includes a cabinet. A refrigeration system includes a compressor, a condenser, an expansion device, and an evaporator. The refrigeration system is charged with a refrigerant. The refrigeration system further includes a modulator having a reservoir and a supply conduit. The reservoir of the modulator is positioned on an outlet conduit of the evaporator. A first end portion of the supply conduit is coupled to an inlet conduit of the evaporator, and a second end portion of the supply conduit is coupled to the reservoir of the modulator. The refrigerant is flowable into and out of the reservoir of the modulator through the supply conduit of the modulator. An ice maker is positioned within the cabinet. The evaporator of the refrigeration system is coupled to the icemaker such that the refrigeration system is operable to chill the icemaker.

An ice maker includes an evaporator configured to freeze water into ice as it flows vertically down a freeze plate. A distributor distributes the water along the top of the freeze plate to form ice across the width of the freeze plate as the water flows downward along the freeze plate. The distributor can be integrated into the evaporator. For example, the distributor and evaporator can have a part in common. The distributor can be formed from two pieces that come together to form the freeze plate. The distributor can have various features that aid in providing a desirable distribution of water along the width of the freeze plate. The freeze plate can be mounted in an ice maker enclosure in thermal communication with the evaporator and to slant forward.

An ice making assembly includes an ice mold and a pump assembly for urging an ice-building spray into the ice mold to form an ice billet. A controller operates the pump assembly to provide the ice-building spray at a first flow rate until the ice billet reaches a predetermined thickness and then operates the pump assembly to provide the ice-building spray at a second flow rate that is less than the first flow rate.

The present disclosure provides an ice machine including a cabinet, a tray disposed inside the cabinet, wherein ice is formed on the tray, a nozzle disposed below the tray and spraying water toward the tray, a storage tank for storing the water to be supplied to the nozzle therein, a water-level sensor disposed in the storage tank, a pump connected to the nozzle by a guide pipe and supplying the water stored in the storage tank to the nozzle, a supply pipe for supplying water to the tray, a water supply valve disposed on the supply pipe, and a controller that opens and closes a flow path of the water supply valve based on a water-level measured by the water-level sensor.

Disclosed is an evaporator assembly for a horizontal type ice making machine. The evaporator assembly includes a plurality of tubes for circulating a refrigerant; a plurality of conductive protrusions, which are thermally coupled to and extending from each of the plurality of tubes; and a non-conductive plate, which is arranged adjacent to the plurality of tubes. The non-conductive plate is defined with a plurality of moulds, wherein each of the plurality of moulds is defined with a provision to receive one of the plurality of conductive protrusions. Each of the plurality of tubes includes a hemispherical structure, configured to enclose a top portion of the mould. The configuration of the evaporator assembly facilitates fast and efficient formation of ice, and there improves the efficiency of the ice making machine.
