Refrigerator

Abstract

There is disclosed a refrigerator comprising a first passage defined in a space in the interior of a heat-insulating box to guide cold air from a evaporator downwardly, and a second passage which guides the cold air that has flowed downwardly in the first passage and rises to return to the evaporator, a partition plate which is disposed within the first passage to divide the passage into a passage which communicates the first passage with the second passage in order to allow the flow of the cold air in contact with the upper storage box, and a passage communicating with the second passage, allowing the cold air to flow into the upper storage box out of contact with the upper storage box; a regulating means which is disposed in a cold air passage from the evaporator, and regulates the flow of the cold air into the passage; and a cold air introducing means disposed in the passage. The cold air introducing means is operated to allow a part of the cold air from the evaporator to flow into the passage without being regulated by the regulating means.
