An embodiment of the present invention relates to a refrigerator. A refrigerator, according to an embodiment of the present invention, can easily detect the withdrawal of a vegetable box that can be withdrawn in the forward direction, due to the placement of a magnetic structure and a switch for detecting the withdrawal of the vegetable box at the rear part of the vegetable box.

A system for blast-freezing items includes a plurality of cells arranged side-by-side, each cell including a housing with a bay space, a plenum, a front air passage, a rear air passage, and a fan. The fan is positioned in the plenum and configured to circulate air through the bay space. Each cell also includes a plurality of channels to separate pathways of air to segments of the bay space. The system also includes a plurality of crane rails extending between rows of cells and at least one crane capable of traveling along the plurality of crane rails to load or unload each of the plurality of cells.

An air supply assembly for a refrigerator, includes: an air duct cover plate defining, together with a refrigerator liner, an air supply space and configured to isolate the air supply space from a storage space in a compartment of the refrigerator, and a centrifugal wind wheel arranged in the air supply space, and axially sucking air in and blowing the air out towards a peripheral side, wherein a plurality of air return ports are provided in the air duct cover plate to allow air in the storage space to enter the air supply space; and the centrifugal wind wheel abuts against an inner side of the air duct cover plate and is configured to suck air in from a rear side thereof, such that air entering the air supply space via the air return ports is sucked in from the rear side of the centrifugal wind wheel.

A blast cell system is provided with simple and scalable designs that prevent short cycling of air flow through any pallets in blast cells. The blast cell includes a plurality of suction channels that provide independent fluid pathways for directing the air drawn from different rows in the blast cell into the fan.

A refrigerator includes an apparatus for producing dairy products. The refrigerator includes an outer cabinet, an inner cabinet provided inside the outer cabinet and including a refrigerator compartment to formed therein, and an dairy product maker provided inside the refrigerator compartment. The dairy product maker includes a case including a suction port and a discharge port to allow cool air to flow in and out, respectively, a container to store the produced dairy product therein, a heater to apply heat to the container to produce the dairy product in the container, ribs protruding from an inner surface of the case to form a cooling flow channel with the inner surface and provided between the suction port and the discharge port to cool the container, and a guide slit to guide the produced dairy product overflowing into the cooling flow channel, to a bottom surface of the case.

The efficiency of a device for cooling or heating objects on a belt that moves through a path of a helix, in which gaseous cooling or heating medium is circulated within the device, is improved by positioning fans that circulate the cooling or heating medium so that the fans are distanced from the top of the helix.

A refrigerator includes a main body including an inner case and an outer case, a storage compartment defined by the inner case, a door configured to open and close the storage compartment, an ice making chamber disposed on a rear surface of the door, a fan configured to supply cold air to the storage compartment and the ice making chamber, and a guide passage formed by being recessed into the inner case to guide cold air supplied by the fan to the ice making chamber. The inner case includes an upper wall, and the guide passage is formed by being recessed into the upper wall of the inner case to be exposed to the storage compartment.

A refrigeration system including a storage chamber configured to store a product at a predetermined temperature. The storage chamber is defined by an inner wall. The inner wall at least partially defines an air plenum. The inner wall includes an opening wall surface, a floor surface, a rear wall surface and a ceiling wall surface. The system also includes a refrigerant circuit including a compressor, a condenser, a condenser fan, an evaporator and an evaporator fan arranged and disposed in an operable configuration to provide refrigeration to the storage chamber. The air plenum includes a conduit arranged and disposed to convey air from an air inlet across the evaporator and into a discharge chamber and out an air outlet. The air outlet is configured to discharge cooled air in a direction toward the opening wall surface.

A refrigerator includes a cabinet, an evaporator, an evaporator cover module, and a cold air supply module configured to communicate with the evaporator cover module. The evaporator cover module includes a rear plate that has a planar shape and that defines the surface of the storage space, a first insulation member located at a rear surface of the rear plate, and a second insulation member spaced apart from the first insulation member and located at a front surface of the inner case. The first insulation member and the second insulation member define a heat-exchange space configured to accommodate the evaporator between the first insulation member and the second insulation member.

A driving mechanism and an air door device including the driving mechanism. A switch signal can be switched when a driving gear rotates forward to one position and rotates backward to another position. The driving mechanism comprises the following components in a shell: a switch; a rotary pressing member rotating toward a pressing direction in which a first pressing portion presses the switch and a departure direction in which the first pressing portion departs from the switch; a force application component for driving the rotary pressing member to rotate toward the pressing direction; a driving gear for driving the rotary pressing member to rotate, a motor for driving the driving gear to rotate and a driven gear being engaged with the driving gear are further arranged in the shell, the driving gear is provided with a first abutting portion and a second abutting portion arranged along the circumferential direction.
