Methods, processes, apparatus, kits and systems for chilling and cooling closed bottled or canned beverages, desserts, and food items to selected desired temperatures by rapidly rotating and counter-rotating the bottled or canned beverages, desserts, and food items that are immersed in cooled liquids in short time spans to a super cooled temperature wherein an effect can cause slush-on-demand.

The present invention relates to a refrigerator unit and/or a freezer unit that has at least one voice control that comprises the following components: at least one detection device for speech recognition and at least one executing device that is configured to carry out at least one action of the refrigerator unit and/or freezer unit on the basis of speech recognized by the detection device.

A refrigerator includes a storage chamber having an opening; a drawer type door to open or close the opening; a display positioned at the drawer type door; a first connector provided at a sidewall of the storage chamber; a second connector provided at the drawer type door and being electrically connected to the display; a first frame coupled to an inner wall of the storage chamber, the first frame to cover the first connector; a second frame coupled to the drawer type door, the second frame to support a storage box; and a wire electrically connected between the first connector and the second connector. The first frame has a first accommodating part to accommodate one portion of the wire and the second frame has a second accommodating part to accommodate another portion of the wire.

Disclosed herein are a refrigerator and a control method of the same. The refrigerator includes a purified water pump which increases a pressure of water, a carbon dioxide regulator which decreases a pressure of carbon dioxide, a mixing pipe which mixes water which introduced from the purified water pump and carbon dioxide which introduced from the carbon dioxide regulator, and produces carbonated water, a user interface which receives a production condition of carbonated water from a user, and a controller which controls the purified water pump and the carbon dioxide regulator such that the pressure of the water and the pressure of the carbon dioxide reach a target pressure corresponding to the input production condition.

A refrigerator including a main body having a storeroom, an inner door rotatably coupled to the main body and having a door opening, an outer door rotatably arranged in front of the inner door to open or close the door opening, a dispenser including a water-intake space and an operation lever and configured to supply water to the water-intake space by manipulation of the operation lever, and an automatic water supplier including a water container installation space formed to have a water container mounted and a water level sensor configured to detect a water level of the water container, and configured to supply water into the water container to fill the water container with a certain amount of water. The water-intake space and the water container installation space may be arranged in the door opening of the inner door to be accessed while the inner door is closed.

A refrigerator and a controlling method thereof are provided. The refrigerator includes a main body including first and second doors, a first motor for opening the first door and a second motor for opening the second door, and a processor configured to, based on a user command for opening the door being obtained, start driving the first motor to open the first door, and after a first time from the time when the first motor has started being driven, start driving the second motor to open the second door.

Methods, processes, apparatus, kits and systems for chilling and cooling bottled or canned beverages, desserts, and food items to selected desired temperatures by rapidly rotating and counter-rotating the bottled or canned beverages, desserts, and food items that are immersed in cooled liquids in short time spans.

A storage container having a sensor unit and a refrigerator having the same. The storage container includes a container body; a container cover coupled to the container body; a sensor module disposed at least at one of the container body or the container cover; and a coupling member provided as to accommodate at least a portion of the sensor module, and detachably coupled to at least one of the container body or the container cover. The sensor unit is detachably coupled to the storage container, and thus a replacement of the sensor unit may be easily performed.

A method and system for cold chain monitoring of perishable goods, includes at least one environmental sensor to monitor at least one environmental parameter, a wide area network interface to communicate with a wide area network, a controller to log a plurality of readings from each of the at least one environmental sensors and to transmit at least one data signal associated with the plurality of readings to the wide area network via the wide area network interface.
