An ice maker includes an ice making unit comprising an evaporator connected to a refrigeration system, an ice holding bin, a sump, a pump, a drain valve, an ozonated water source, and a controller. The controller activates the ozonated water source supplying a first volume of ozonated water to the sump, thereafter activates the pump to circulate the first volume of ozonated water from the sump to the ice making unit, once a predetermined sterilization time has been reached, the controller turns off the pump and drains the first volume of ozonated water from the sump. The controller initiates an ice making mode, and activates the ozonated water source to supply a second volume of ozonated water to the sump, thereafter activates the pump to circulate the second volume of ozonated water from the sump to the ice making unit forming ozonated ice on the evaporator, and initiates an ice harvest mode to remove the ozonated ice from the evaporator and delivers it to the ice holding bin.

A domestic refrigeration appliance includes a refrigerator compartment set to a first target temperature by a regulation or control unit, an ice maker compartment being separated from the refrigerator compartment by an inner insulation layer and set to a second target temperature by the regulation or control unit and an ice maker in the ice maker compartment. The regulation or control unit can switch between a normal ice making mode and a reduced-power ice making mode in which the target temperature in the ice maker compartment lies between the target temperature in the refrigerator compartment and the target temperature in the ice maker compartment in the normal ice making mode.

A refrigerator having an ice-making device evaporator in addition to a refrigerator storage room evaporator. The ice-making device includes an ice tray and a cooling pipe contacting an outer surface of the ice tray. A refrigerant flows in the cooling pipe and directly cools the ice tray. The ice-making device evaporator receives the refrigerant from a condenser and supplies it to the cooling pipe. A heat insulation member wraps around the cooling pipe and can prevent the cooling pipe from exchanging heat with ambient air.

A refrigerator appliance is generally provided herein. The refrigerator appliance may include a cabinet, an icebox liner, an icemaker, an ice bin, and a circulation duct. The cabinet may define a one or more chilled chambers. The icebox liner may be attached to the cabinet. The icebox liner may define a sub-compartment in which the icemaker may be mounted. The ice bin may define a storage volume within the sub-compartment to receive ice from the icemaker. The circulation duct may extend within the sub-compartment in conductive thermal communication with the icemaker. The circulation duct may define an air passage in fluid communication with one of the chilled chambers and fluid isolation from the storage volume.

A valve device for an ice dispensing conduit includes a bearing structure having a passage to be coupled with the conduit, an obturator mounted rotatable in the bearing structure between a closed position and an opened position, and a motor for rotating the obturator between the closed position and the opened position. A wire made of a shape-memory material, capable of shrinking when an electric current flows therethrough, has one end anchored to the bearing structure and the other end coupled with the obturator through a transmission mechanism. A flow of an electric current in the shape-memory wire causes a shrinking thereof and a consequent rotation of the obturator towards the opened position, and an interruption of such current allows the shape-memory wire to re-expand and the obturator (12) to return towards its closed position.

The present disclosure discloses a display panel turnover device. The display panel turnover device includes: a holder comprising two inverted-V shaped supports arranged oppositely and a rotating shaft pivotally assembled on top ends of the two inverted-V shaped supports, wherein each inverted-V shaped support comprises a front leg and a rear leg; an adjustment lever having a first operating position and a second operating position, located between two front legs and two rear legs and substantially parallel to the rotating shaft; a frame configured to retain a periphery of a display panel therein, wherein a top of the frame is secured to the rotating shaft, and a bottom of the frame is secured to the adjustment lever; and a front door and a rear door respectively arranged at a front side and a rear side of the frame and capable of being opened and closed.

Provided is a refrigerator including a cabinet having a refrigerating compartment and a freezing compartment defined therein, and an ice-maker disposed in the freezing compartment, wherein the ice-maker includes a cold-air hole for receiving cold air, an upper tray having a plurality of hemispherical upper chambers defined therein, a lower tray pivotably disposed below the upper tray, wherein the lower tray has a plurality of lower chambers defined therein respectively connected to the upper chambers by pivoting, wherein each of the lower chambers and each of the upper chambers connected with each other define an ice chamber for forming spherical ice therein, a driver for pivoting the lower tray, and at least one shield formed on an outer face of the upper tray and corresponding to at least one of the ice chambers respectively, thereby to reduce the cold-air from invading the at least one corresponding ice chamber.

An ice vending machine automatically provides ice to a customer based upon a request from the consumer for the ice. In some embodiments, the ice vending machine includes a transfer box to transfer ice from a horizontal auger to an inclined auger. In some embodiments, the inclined auger motor is mounted at the top of the inclined auger. The inclined auger motor may drive the inclined auger by way of a chain and sprockets or directly drive the inclined auger without a chain or sprockets. In some embodiments, a lip shelf is located at an edge of the holding vessel floor. In some embodiments, a rear wall is removable from the holding vessel. In some embodiments, the ice machine includes an awning, a top hat, or an ice maker canopy. In some embodiments, the ice vending machine includes an improved motor and chain layout.
