A refrigerator includes: an inner case including a plurality of plates formed by injection-molding; an outer case couplable with an exterior of the inner case; and an insulation between the inner case and the outer case. A first plate of the plurality of plates includes a first coupling portion formed along an edge of the first plate, and a second plate of the plurality of plates includes a second coupling portion formed along an edge of the second plate and couplable with the first coupling portion. The first coupling portion includes an insertion protrusion. The second coupling portion includes: an accommodating portion forming an accommodating groove in which the insertion protrusion is inserted; and a catching portion configured to prevent the insertion protrusion from departing from the accommodating groove; and an inner rib protruding from an inner surface of the accommodating portion to be inserted in the insertion groove.

A refrigerator which comprises a housing, a refrigerating inner liner, a freezing inner liner and a foaming layer formed between the housing, the refrigerating inner liner and the freezing inner liner; the housing comprises a back plate and two side plates, and the foaming layer comprises a first foaming zone disposed close to the back plate, a second foaming zone disposed close to the side plates and a third foaming zone disposed in an interior of the middle beam, and the third foaming zone is connected to the second foaming zone; the refrigerator further comprises a sealing device that at least partially spaces the first foaming zone apart from the third foaming zone. After the foaming material reaches the first foaming zone, a lot of foaming material may be limited from entering the interior of the middle beam, so that the filling uniformity can be further improved effectively.

A vacuum insulated cabinet structure includes an exterior wrapper with a front edge extending around an opening thereof. A liner includes a front edge extending around an opening of the liner, wherein the liner is disposed inside of the wrapper. A thermal bridge includes an outer coupling portion and an inner coupling portion. In assembly, the outer coupling portion is overmolded to the front edge of the wrapper, and the inner coupling portion is overmolded to the front edge of the liner to form a sealed vacuum cavity (VC) between the wrapper and the liner. The thermal bridge is formed in a mold in which the wrapper and liner are partially disposed to form a unitary composite structure.

A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate. The support includes a first support plate provided by coupling at least two partial plates to support one of the first plate or the second plate, and a second support plate that supports the other one of the first plate or the second plate.

Disclosed are a foaming material, a thermal insulation cabinet, and preparation methods therefor. The foaming material comprises 100 parts of a combined polyol, 10-30 parts of a foaming agent composition, and 120-150 parts of an isocyanate. In the present invention, the type of the polyol used in a foaming system is adjusted in order to increase the content of a polyester polyol and reduce the content of a polyether polyol, such that the compressive strength of the foaming material is significantly improved without increasing or changing the injection amount.

A vacuum adiabatic body includes a first plate; a second plate; a seal; a support; and an exhaust port, wherein an extension tab extending toward the third space to be coupled to the support is provided to at least one of the first and second plates, and the extension tab extends downward from an edge portion of the at least one of the first and second plates.

An appliance includes an outer wrapper and an inner liner that form a structural cabinet having an insulating cavity defined between the inner liner and the outer wrapper. An elliptical insulation port is defined within the outer wrapper, wherein the elliptical insulation port is configured to allow passage of a cylindrical insulation conduit when the insulation conduit is positioned at an oblique angle relative to the structural cabinet. An insulation material is disposed within the insulating cavity. A sealing cap covers the elliptical insulation port, wherein the sealing cap includes a protrusion that extends at least partially into the insulating cavity.

A structure of an ice making compartment of a side by side type refrigerator to enhance ice making efficiency and to reduce energy consumption. The ice making compartment may be separately provided between a refrigerating compartment and a freezing compartment and be insulated from the refrigerating compartment and the freezing compartment. A portion of a refrigerant pipe is inserted into the inside of the ice making compartment so as to directly cool down the ice making compartment. A front opening of the ice making compartment can be closed by an ice bucket, and the ice bucket can be inserted into or drawn from the ice making compartment with being accessible without opening a refrigerating compartment door and a freezing compartment door.

A vacuum insulation body includes an outer box (2), an inner box (3), open-cell urethane foam (4) in the insulation space (1b) between the outer box (2) and the inner box (3); and a vacuum outlet (6) in one of the outer box (2) and the inner box (3). The urethane foam (4) includes a through passage (8a) leading to the vacuum outlet (6). The vacuum outlet (6) is sealed after the insulation space (1b) filled with the urethane foam (4) is vacuum-evacuated.

An insulation system for an appliance includes a first vacuum insulated structure having a first set of sidewalls that define a first refrigerating compartment, a second vacuum insulated structure having a second set of sidewalls that define a second refrigerating compartment and a medial insulation structure having a rigid perimeter wall. The rigid perimeter wall includes a front portion that defines at least one hinge support adapted to support an appliance door. The rigid perimeter wall defines an insulating cavity that is filled with an insulating material. The first vacuum insulated structure engages a first edge of the perimeter wall and the second vacuum insulated structure engages a second edge of the perimeter wall.
