Abstract:
A foaming apparatus for foaming a refrigerator cabinet includes a frame including a supporting structure, and first and second foaming jigs restrained to the supporting structure opposite to each other relative to the supporting structure. The first and second foaming jigs being respectively arranged in a lower position and in an upper position relative to a vertical direction of the foaming apparatus in an operating condition thereof. Each foaming jig includes a bottom wall, peripheral walls configured to enclose an outer shell of the refrigerator cabinet, a plug configured to engage an inner shell of the refrigerator cabinet, and at least one injection head configured to carry out injection of a foaming mixture into the refrigerator cabinet received therein. The peripheral walls and the plug are restrained to the supporting structure, whereas the bottom wall is removably mounted to the peripheral walls.
Abstract:
A heat-insulation box, includes: a heat-insulation-box main body that has a space; a door that seals the space; and a partition plate that partitions the space, wherein the partition plate includes (i) a design plate that is placed at a side of the door, (ii) a first plate part and a second plate part that are each provided at both edges of the design plate, (iii) a heat-insulation material that is located in a region surrounded by the design plate, the first plate part, and the second plate part, and (iv) a heat-insulation member that is placed in at least one of a gap between the design plate and the first plate part, and a gap between the design plate and the second plate part.
Abstract:
A refrigerator in which an ice making chamber case including a horizontal wall, a vertical wall, a front opening and a front edge is coupled to an inside of an inner case, to form an ice making chamber. A case insulator is disposed in a wall space of the ice making chamber case. The case insulator is foamed separately from a body insulator which is foamed between inner and outer cases of a refrigerator body. Since the case insulator is foamed separately from the body insulator, it is possible to easily achieve foaming of the case insulator. It is also possible to prepare the ice making chamber case separately from molding of the inner case.
Abstract:
A refrigerator having an improved structure configured to increase the energy efficiency includes a main body provided with an inner case and an outer case, a storage compartment formed inside of the inner case, an insulation material provided between the inner case and the outer case to insulate the storage compartment and a flange having the anisotropy having different heat resistance distribution to insulate the storage compartment, together with the insulation material.
Abstract:
Embodiments of the present disclosure relate to a polyurethane foam, a refrigerator including the same, and a method of manufacturing polyurethane foam.According with the present inventions, a refrigerator, comprising a polyurethane foam formed of a composition for preparing polyurethane, includes a cabinet; a door configured to open and close the cabinet; and a thermal insulation disposed in at least one of the cabinet and the door, wherein the thermal insulation includes a polyurethane foam-forming polyol system comprising a fiber having hydroxyl groups; and isocyanate.
Abstract:
A refrigerator in which a refrigerant pipe assembly including a refrigerant pipe and a refrigerant pipe insulator coupled to the refrigerant pipe is inserted into an inner case in an inward direction from an outside of the inner case through an opening of the inner case. A portion of the refrigerant pipe insulator is disposed in the ice making chamber, and a remaining portion of the refrigerant pipe insulator is disposed between the inner case and the outer case. The refrigerant pipe insulator portion disposed between the inner case and the outer case is supported by a body insulator foamed between the inner case and the outer case. In accordance with this structure, it is possible not only to insulate the refrigerant pipe, but also to easily insert the refrigerant pipe into the ice making chamber and to keep the refrigerant pipe in a firmly-supported state.
Abstract:
Example insulated pliable door panels or curtains include various internal vapor barriers. The vapor barriers have a relatively high water vapor transmission rate that inhibits water vapor from permeating through the door panel. With such vapor barriers, outer sheets of the door panel can be made of polyurethane or other tough materials that might have an inadequate water vapor transmission rate. In some examples, the vapor barrier encircles or encloses a thermally insulating pad. In some examples, the door panel includes a sleeve or pocket that holds the vapor barrier in place. Some examples include means for draining water that might condense within the door panel.
Abstract:
A refrigerator includes an insulated cabinet structure and a cooling system. A door assembly includes a perimeter structure that is movably mounted to the insulated cabinet structure and an outer door that is movably mounted to the perimeter structure whereby the outer door can be moved between open and closed positions relative to the perimeter structure when the perimeter structure is in its closed position The outer door may comprise a vacuum insulated structure including porous core material disposed in a cavity of the outer door.
Abstract:
The invention pertains to coolers. Prior cooler designs had an unsegregated implicit void of unused air volume. This void was conducive to air eddy currents, which resulted in accelerated warming of the contents. The invention provides the means to disrupt the air eddy currents through a series of collapsible/expandable air cells. The disruption results in the increase of the insulation ability of the cooler. The collapsible/expandable feature allows the cooler to have content added/removed as needed, and allows the air cells to be increased in volume when content is removed.
