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 an upper tray made of an elastic material, and having a plurality of hemispherical upper chambers defined therein, a lower tray made of an elastic material, wherein the lower tray comes into contact with the upper tray by pivoting to define a plurality of spherical ice chambers therebetween, a driver for pivoting the lower tray to open and close the upper tray and the lower tray, and each rib formed along a circumference of each upper chamber or each lower chamber in contact with each other.

An ice-making device in a refrigerator including water blocking walls configured to prevent water supplied to an ice tray from straying outside the ice tray. The ice-making device includes an upper frame and a lower frame. A water supply port is disposed in a rear wall of the upper frame and configured to supply water to an ice tray between the upper frame and the lower frame. An upper sidewall protrudes downward from the upper frame. A main water-blocking rib protrudes from the rear wall and configured to prevent water supplied from the water supply port from straying along the upper sidewall. An auxiliary water-blocking rib protrudes from the upper sidewall and can further prevent the water supplied from the water supply port from straying along the upper sidewall.

A refrigerator includes an ice-making unit disposed in the door and can make ice through direct cooling by a refrigerant without using cold air flow. A cold air generation system operates to circulate the refrigerant for supplying a cold air flow for the refrigerator. A refrigerant pipe is installed in the refrigerator main body to branch off some refrigerant from the cold air generation system. An ice-making pipe is installed within the ice-making unit and receives the refrigerant from the refrigerant pipe. Water freezes into ice through heat transfer between the ice-making unit and the ice-making pipe containing refrigerant. A soft pipe is disposed around a hinge shaft of the refrigerator main body and the door and configured to interconnect the ice-making pipe and the refrigerant pipe in a twistable manner.

A water switch assembly for a nugget ice making assembly is provided. The ice making assembly includes a hollow auger rotatably mounted within a reservoir and configured for extruding ice. The water switch assembly includes a water supply pipe that extends vertically through the center of the ice making auger and reservoir. The water switch assembly is in fluid communication with a water inlet and includes a capacitance probe for measuring the water level in the reservoir. In this manner, the water switch assembly is configured to control the flow of water to the reservoir in response to the water level measured by the capacitance probe.

A refrigerator includes a refrigerator main body configured to define an outer shell of the refrigerator and a door configured to open and close an internal space of the refrigerator main body. The refrigerator further includes an ice-making unit provided in the door and a cold air generation unit configured to circulate a refrigerant so that a cold air is supplied to the internal space. The refrigerator further includes an ice-making pipe installed within the ice-making unit so that the ice-making unit makes heat exchange with the refrigerant, a refrigerant pipe installed in the refrigerator main body so as to receive the refrigerant from the cold air generation unit, and a soft pipe disposed around a folding portion of the refrigerator main body and the door and configured to interconnect the ice-making pipe and the refrigerant pipe in a stretchable manner.

Exemplary embodiments of a device and method for making clear ice spheres employing a large half mold (11) releasably connected to a small half mold (30), and an insulated vessel (70). When the device is filled with liquid and submitted to freezing temperatures the liquid freezes from the top down leaving a clear ice sphere in the mold.

Non-plumbed appliances and filters are provided. A filter includes a body which includes a sidewall extending along a longitudinal axis between a first end wall and a second end wall, the body defining a body interior. The filter further includes an inlet defined in the body, and a nozzle protruding from the second end wall along the longitudinal axis and defining an outlet, the nozzle offset along an outer surface of the second end wall from a centroid of the outer surface. The filter further includes a tab configured on the body, and a filter medium disposed within the body interior, the filter medium operable to remove contaminants from water flowing through the filter medium.

Stand-alone ice making appliances are provided. An appliance includes a container defining a first storage volume for receipt of ice, a water tank defining a second storage volume for receipt of water, and a pump in fluid communication with the second storage volume. The appliance further includes an ice maker which is in fluid communication with the pump for receiving water from the pump. The appliance further includes a filter, the filter including a filter medium operable to remove contaminants from water flowing through the filter medium, the filter positioned upstream of the ice maker in a flow direction of water from the second storage volume to the ice maker.

A method for building an ice structure includes making a plurality of ice logs and attaching the ice logs together to form a support structure. The support structure may be two or more stories high and may be constructed by freezing the ice logs together.
