Provided are a device (100) for self-adaptive regulation of air volume and a refrigerator (200) having the same. The regulating device (100) comprises: a drainage and air guide cavity (1), arranged on the back of a freezing chamber (201) of a refrigerator, the drainage and air guide cavity (1) comprising a funnel-shaped air collecting cavity (11) and a conical air outlet cavity (12) connected to the funnel-shaped air collecting cavity (11), an outlet of the conical air outlet cavity (12) facing a refrigerating chamber; a drainage tongue (2), provided in the conical air outlet cavity (12) so as to create a first outlet duct (122) and a second outlet duct (123) within the conical air outlet cavity (12), an inlet (20a) of the first outlet duct (122) being located on an extension line of a left side wall (113) of the funnel-shaped air collecting cavity (11) and an inlet (21a) of the second outlet duct (123) being located on an extension line of a right side wall (112) of the funnel-shaped air collecting cavity (11); and a fan (3) arranged inside of the funnel-shaped air collecting cavity (11). By rotating the fan (3), cold air is conveyed through the first outlet duct (122) and the second outlet duct (123) and into a refrigerating chamber (202) under the guide of the left side wall (113) or right side wall (112) of the funnel-shaped air collecting cavity (11).

The present invention provides a highly reliable and safe heating device that can uniformly heat an object to be heated and provides a refrigerator having a storage space in which frozen products as storage products can be easily thawed to a high-quality state. A heating device of the present invention includes an oscillation electrode disposed on one hand of the heating space and having an electrode surface on which an electric field concentration region is formed, a counter electrode disposed on the other hand of the heating space and having an electrode surface that faces the electrode surface of the oscillation electrode, and a high-frequency electric field forming unit for forming a high-frequency electric field applied to between the oscillation electrode and the counter electrode.

A refrigerator having a cool air circulation unit for directly supplying heat-exchanged cool air to a storage compartment is disclosed. The cool air circulation unit supplies and discharges the cool air, which has been heat-exchanged in an evaporator, to and from the storage compartment through a flow passage provided inside a partition.

A refrigerator includes a refrigerator case, a freezer case disposed below the refrigerator case, a door disposed at a front of the refrigerator case, an ice maker disposed at the door, an evaporator disposed at a rear of the freezer case, an ice maker supply duct supplying the cold air to the ice maker, and an ice maker return duct supplying the cold air from the ice maker to the freezer compartment. An upper portion of the ice maker return duct extends from a rear of one side surface of the freezer case to a front of one side surface of the refrigerator case, a lower portion of the ice maker return duct extends in a vertical direction from the rear of one side surface of the freezer case, and the lower portion bends from the upper portion toward the other side surface of the freezer case.

An appliance ice-making compartment includes a housing which defines an inlet aperture and an outlet aperture. A first ice tray is disposed at a first height within the housing. A second ice tray is disposed at a second height within the housing where the first height is closer to a top of the housing compared to the second height. The second ice tray is closer to the inlet aperture compared to the first ice tray. An inlet duct is in fluid communication with the inlet aperture and configured to direct air toward the first ice tray and the second ice tray.

A refrigerator includes a storage compartment to which cold air is supplied through a cold air outlet, and a shelf mounted to the storage compartment. The shelf includes a shelf frame provided to form a rim of the shelf, and a cold air regulator manipulated from one side of the shelf frame so as to adjust an amount of cold air discharged from the cold air outlet to the storage compartment. The cold air regulator includes a connecting member configured to be slidable along the rim of the shelf.

A refrigerator appliance may include a cabinet, a door, a sealed cooling system, and an ice cream unit. The door may include a door liner defining an icebox compartment. The door may include a chilled air supply opening and a chilled air return opening spaced apart from the chilled air supply opening. The ice cream unit may be disposed within the icebox compartment. The ice cream unit may include a freezing tank, a rotatable auger extending into the freezing tank, a tank jacket, and a unit duct or support base. The tank jacket may receive the freezing tank and define a cooling passage extending about the freezing tank from a jacket inlet to a jacket outlet. The jacket outlet may be open to the icebox compartment to exhaust air from the cooling passage to the icebox compartment.

A refrigerator including a housing mounted at a rear surface of a door to define a storage space of food, a basket disposed inside the housing, a duct extending to the housing from one side bf an evaporator to supply cold air generated by the evaporator into the storage space of the housing, and a fan assembly coupled to the duct to allow the cold air to be forcibly supplied.

A refrigerator includes a wall covering assembly having a top wall spaced-apart from a top wall of a liner, and a rear wall spaced-apart from a rear wall of the liner. The wall covering assembly includes a pattern of ports for providing outwardly directed cooled air to the refrigerator cabinet from a duct assembly. The duct assembly is configured to deliver cooled air through the ventilated portion of the wall covering assembly and also deliver cooled air to a front portion of the refrigerator cabinet via a downwardly directed air curtain. The air curtain disrupts the outward flow of air from the ventilated portion of the wall covering assembly before the cooled air reaches a gasket assembly disposed around the refrigerator doors. Angled venting slots disposed on the wall covering assembly direct air towards inner surfaces of the doors without disruption from the air curtain.

A refrigerator includes a storage compartment to which cold air is supplied through a cold air outlet, and a shelf mounted to the storage compartment. The shelf includes a shelf frame provided to form a rim of the shelf, and a cold air regulator manipulated from one side of the shelf frame so as to adjust an amount of cold air discharged from the cold air outlet to the storage compartment. The cold air regulator includes a connecting member configured to be slidable along the rim of the shelf.
