Abstract: A refrigerator includes an inner case forming a storage compartment; a cold air duct guiding the flow of air within the storage compartment and forming a heat exchange space with the inner case; an evaporator disposed in the heat exchange space between the inner case and the cold air duct; a bypass passage disposed at the cold air duct so as to allow a portion of the flow of air to bypass the evaporator; a sensor disposed in the bypass passage and including a sensor housing, a sensor PCB, a heating element, a temperature element for sensing a temperature of the heating element, and a molding material with which the sensor housing is filled; a defroster for removing frost formed on the surface of the evaporator; and a control unit for controlling the defroster on the basis of the value output from the sensor.

Abstract: A refrigerator includes a body having a storage space. The body includes an inner case having the storage space, an outer case having an inside surface spaced a predetermined gap from an outside surface of the inner case to house the inner case, a vacuum space provided between the inner case and the outer case sealed to maintain a vacuum state for heat insulating between the inner case and the outer case, a supporting portion provided to contact with the outside surface of the inner case and the inside surface of the outer case to maintain a spaced state of the vacuum space, and a dewing preventive unit adjacent to the supporting portion for preventing dewing from taking place at the outer case by suppressing surface temperature drop of the outer case caused by cold conducted from the inner case to the outer case through the supporting portion.
