Abstract: A coffee maker and a control method therefor are disclosed. The disclosed coffee maker controls a dripper valve module to be closed in a first water supply section corresponding to a pre-wetting process so as to close an extraction hole, and controls the dripper valve module to be opened in a second water supply section corresponding to a coffee extraction process so as to open the extraction hole. Accordingly, a coffee drip process similar to a hand drip operation can be implemented.

Abstract: A vacuum adiabatic body includes a heat exchange pipeline and a sealing assembly. The heat exchange pipeline includes at least two pipelines which pass through a first plate and a second plate to allow a refrigerant to move between inner and outer spaces. The sealing assembly allows the heat exchange pipeline to pass through the first plate and the second plate without contacting a vacuum space provided between the first and second plates.

Abstract: A vacuum adiabatic body includes a conductive resistance sheet which blocks heat conduction between plate members, and a sealing frame which covers the conductive resistance sheet. The sealing frame includes a side surface part, an outer surface part which is bent and extends from a side of the side surface part, and an inner surface part which is bent and extends from the other side of the side surface part. The sealing frame is provided as a configuration of a concave groove in which the width between the outer surface part and the inner surface part is smaller than the width of the side surface part. According to the present invention, a peripheral portion of the vacuum adiabatic body can be stably maintained.
