Abstract: An exterior material of a home appliance having improved corrosion resistance and fingerprint resistance by changing a treatment method of a surface of the exterior material, and the home appliance including the same, and a manufacturing method therefor are provided. The method of manufacturing the exterior material of the home appliance, the method including applying a diamond like carbon (DLC) coating on the substrate to form a DLC coating layer; and conducting anti-fingerprint coating to form the anti-fingerprint coating on the DLC coating layer.

Abstract: Disclosed herein are an apparatus of manufacturing a panel for home appliance by performing uniform surface processing on the panel and a method of manufacturing a home appliance by performing uniform surface processing on a panel. The apparatus of manufacturing a panel for home appliance includes a contacting roller configured to perform surface-processing on a panel that is to be processed; a pressing roller configured to press the panel toward the contacting roller; and a supporting roller configured to support a center middle portion of the contacting roller.

Abstract: Disclosed herein are a ceramic plate to which an industrial fiber is attached to one surface thereof in order to reinforce the strength of a material and a refrigerator including the same. In accordance with one aspect of the present disclosure, a ceramic plate includes a porous ceramic substrate, an adhesive layer bonded to one surface of the porous ceramic substrate, and a reinforcement material layer bonded on the adhesive layer and formed of a fabric woven from at least one industrial fiber selected from the group consisting of an aramid fiber and a carbon fiber.

Abstract: A refrigerator, according to one embodiment, includes an inner case with an improved structure. The inner case includes a plurality of plates forming faces of the inner case, and one or more frames disposed between the plurality of plates to support the plurality of plates. The plates and the frames may be molded separately, without being molded as one body, so that the plates and the frames can be formed with various materials.

Abstract: A transverse hairline forming apparatus includes a coil supporting unit to which a stainless steel coil is rotatably disposed; a coil winding unit spaced apart from the coil supporting unit, the coil winding unit holding and winding an end of the stainless steel coil; and at least one pair of surface treatment units disposed between the coil supporting unit and the coil winding unit, the at least one pair of surface treatment units configured to form transverse hairlines on a surface of the stainless steel coil perpendicular to a winding direction of the stainless steel coil. While the stainless steel coil is unwound and rewound on the coil winding unit, when the stainless steel coil passes below the at least one pair of surface treatment units, the at least one pair of surface treatment units form the transverse hairlines on the surface of the stainless steel coil.
