An insulating structure for an appliance includes an outer layer and an inner layer, wherein an insulating cavity is defined therebetween. A plurality of hollow nano-spheres are disposed within the insulating cavity, wherein each of the hollow nano-spheres includes a diameter in the range of from approximately 50 nanometers to approximately 1000 nanometers and has a wall that defines the internal space, and wherein the wall of each hollow nano-sphere has a thickness that is in a range of from approximately 0.5 nanometers to approximately 100 nanometers. A fill material is disposed in the insulating cavity and wherein the fill material is disposed in the space defined between the plurality of hollow nano-spheres, and wherein the fill material includes at least one of powdered silica, granulated silica, other silica material, aerogel and insulating gas.

A refrigerator includes a cabinet, a door configured to open/close the cabinet, an outer plate defining a front surface of the door and having an opening formed therein to pass through the door, a door liner defining a rear surface of the door, lighting members configured to illuminate storage spaces of the door and the cabinet, a transparent panel assembly mounted to shield the opening and allowing the storage spaces to be selectively seen according to an ON/OFF state of the lighting members, an insulator filled between the outer plate and the door liner, and a blocking part arranged inside the door along a periphery of the transparent panel assembly and detachably coupled to a peripheral surface of the transparent panel assembly to fix the transparent panel assembly.

A refrigerator appliance includes an icemaker that is selectively closeable by a door. An outer gasket is positioned about an edge of the door and a sealing gasket is positioned around a center portion of the door inside the outer gasket. A plurality of protrusions extend from a rim of the icemaker. A liner is aligned with and spaced apart from the rim. A first gasket and a second gasket are positioned between the box and the liner.

A home appliance contains a housing which surrounds an internal space. The housing has an outer side wall facing outside, an inner side wall spaced apart from the outer side wall, a thermal insulation material which fills a spacing between the side walls, and a front flange connected to the inner side wall from one side and to the outer side wall from the other side. An external sealing member is provided on a connection region of the housing where the front flange connects to the inner side wall, so as to provide a barrier to the thermal insulation material.

A filling system for a vacuum insulated structure is provided having a powder processor including a hopper having an inner hopper wall and an outer hopper wall. The filling system also includes a vacuum insulated structure having a liner positioned inside a wrapper, a trim breaker coupling an outer liner edge and an outer wrapper edge to form a shell defining an internal cavity with at least one gas permeable feature positioned in the internal cavity configured to help apply a vacuum. A loading port is positioned on a surface of the shell. The powder processor loads the shell with a heated and at least partially degassed vacuum insulation material through the loading port while a vacuum is applied to the shell through the at least one gas permeable feature.

A method and system for forming an insulation package for use in a vacuum insulated structure is provided. A slurry containing a liquid and an insulation material is formed. The slurry can be supplied to an envelope under vacuum, wherein the envelope is gas-permeable and permeable to the liquid. At least a portion of the liquid is drawn through the envelope and at least a portion of the insulation material is retained within the envelope to form an insulation package. One or more insulation packages can be disposed within an insulating cavity and the insulating cavity can be evacuated to decrease a pressure therein to form a vacuum insulated structure.

The present invention relates to a refrigerator and, in particular, to a refrigerator characterized by comprising: a main body including an outer case and an inner case provided inside the outer case so as to provide an ice-making chamber and a refrigerating chamber in the upper part and a freezing chamber in the lower part; and a partition wall coupled to the inner case so as to form the ice-making chamber, wherein a bead portion is formed in the inner case, and a concave portion fitting the bead portion is formed in the partition wall, and thus, the assembly position of the partition wall coupled to the inner case can be more easily identified and set through the fitting of the bead portion and the concave portion.

This refrigeration device is provided with: an evaporator configuring a refrigeration circuit; a cascade condenser configuring the refrigeration circuit; and a thermal insulation board arranged between the evaporator and the cascade condenser.

The invention is provided with a housing which has an inner space open in a first direction, a partition body which divides the inlet of the inner space into a plurality of openings arranged next to each other in a second direction perpendicular to the first direction, a door which is provided to each of the openings and which closes the opening from the first direction side, a first vacuum heat insulating material which is disposed inside the partition body, and a second vacuum heat insulating material which is disposed inside the door. The first vacuum heat insulating material and the second vacuum heat insulating material are arranged so as to overlap each other when viewed from the first direction side or from the second direction side.

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.
