The present disclosure relates to a refrigerator and a control method therefor. A refrigerator may include: a cabinet; a drawer provided to move in and out of the lower storage space and opening and closing the lower storage space; a lifting unit provided inside the drawer and elevated up and down; an opening/closing motor providing power for opening and closing the drawer; a lifting motor connected to the lifting unit and providing power for elevating the lifting unit; and a controller to reopen the drawer when the closing of the drawer is detected while the lifting unit is being elevated or the elevation of the lifting unit is completed.

An apparatus provides pulsed impingement jets to a sub-chamber within an impingement hood of a freezer, and includes a blower having an inlet and an outlet at an interior of the freezer; a duct having a first end in fluid communication with the outlet and a second end opening into the sub-chamber; and a flow valve disposed in the duct proximate the second end opening, the flow valve movable in repetitive open and closed positions for providing repetitive, discrete pulses of the impingement jets from the second end opening of the duct into the sub-chamber.

A refrigerator includes a cabinet defining a storage chamber, a door configured to open and close the storage chamber, a cooling device configured to cool the storage chamber, an elevation device configured to move a container in the storage chamber upward and downward, a locking device disposed at the elevation device and configured to, based on the elevation device being rotated about a front end of the elevation device in a folded state, lock the elevation device to the folded state and maintain the folded state, and a support plate that is disposed at the elevation device and includes a handle disposed at a rear portion of the support plate.

A method of preparing meals in a computerized kitchen workspace is set forth. The computerized kitchen workspace includes one or more robots for preparing and cooking food in the kitchen workspace. Kitchen appliances may be automatically controlled according to a recipe. The one or more robots may access kitchen items necessary for meal preparation by rotating automated shelves. The meal may then be automatically prepared by the one or more robots. Automated storage shelves may be provided with electrical power for powering kitchen appliances found on the shelves.

A refrigerator that includes: a cabinet; a first door; a second door; a moving basket that includes: a basket, a moving frame that is arranged to have a first distance between the moving frame and the basket, and a bridge that couples the basket to the moving frame; a rail that is coupled to the first door and that is configured to guide the moving basket; a supporting unit that is projected from the bridge toward the rail and that supports the moving basket; a lever that, based on user manipulation, to moves between a first position and a second position, wherein the moving frame is configured to accommodate at least a portion of the lever; and a stopper that is coupled to the rail based on a position of the lever and that is configured to stop the moving basket is disclosed.

A refrigerator includes: a cabinet; a drawer door assembly including a front panel door part and a drawer part that defines an accommodation space; a rail that movably configured to connect the drawer door assembly to the cabinet and enable the drawer door assembly to insert into and withdraw from the cabinet; a driving device located at the front panel door part and configured to provide power; and an elevation device located in the drawer part and configured to be coupled to the driving device and elevate a portion of the drawer part relative to the front panel door part. The driving device includes: a motor assembly configured to provide driving force; a screw assembly configured to perform an elevation operation based on the driving force; and a lever that connects the screw assembly to the elevation device and that is configured to rotate based on the elevation operation.

A freezing spiral net chain structure includes a plurality of chain links successively arranged in a travelling direction of a rail. Transmission teeth are arranged at inner ends of the chain links. Engagement teeth are arranged at two sides of the chain links. The engagement teeth of the adjacent chain links are engaged with each other. Axial holes are disposed between the mutually engaged engagement teeth. Rotary shafts are inserted into the axial holes. A metal piece is connected between outer ends of every two adjacent rotary shafts. The metal piece may bear a load from an outer-end spiral net, and since a coefficient of expansion of metal is smaller than that of plastic, deformation between the adjacent rotary shafts as a result of cold shrinking is reduced. The metal piece is different from the rotary shafts of the plastic spiral conveying net chain in terms of pitch.
