Abstract: An armrest according to one embodiment of the present invention includes a case including a passage which guides a flow of air while the air is introduced and discharged and a through-hole which is formed via the passage to allow the air to be discharged outward, a fan located inside the case and by which the air is introduced and discharged through the passage, a heating element configured to supply heat to the air discharged by the fan and an outer surface of the case, and a supporter configured to support an external force applied to the case in at least two directions to keep a shape of the case.

Abstract: An ice maker includes an ice tray with partitioned spaces for receiving ice-making water, an ejector for ice-separating an ice in the ice tray, a detector unit for detecting at least one of a position of the ejector and a temperature of the ice tray, a control box provided to be opposite to the ice tray and including a printed circuit board and a motor for driving the ejector therein, and a planar heater provided in the ice tray and including a heating element of a metal thin film and an insulating member to wrap the heating element such that the planar heater is pressured by virtue of an instrument provided in the ice tray to be bonded to or in closely contacted with the ice tray.

Abstract: A storage container is disclosed. A storage container according to one embodiment of the present invention comprises: at least one accommodation portion for accommodating goods; and a contact portion formed at the inner lateral surface of the accommodation portion and transferring heat to the goods by making contact with the inner lateral surface of the goods, wherein the inner lateral surface of the accommodation portion is formed in any one of a non-circular shape, a combined shape of a circle and a non-circle, a combined shape of circles having different radii of curvature, a combined shape of a non-circle and a non-circle, a combined shape of a circle or a non-circle and a polygon, a combined shape of a circle or a non-circle and a plane, a combined shape of different shapes of polygons, and a polygonal shape.

Abstract: A filter has a multi-layered structure for removing impurity particles from a molten metal. The filter includes: a plurality of filter layers sequentially disposed along the flow direction of the molten metal in a downward direction and comprising a plurality of pore channels, wherein the filter layers disposed upstream comprise larger pore channels than those of the filter layers disposed downstream.
