Refrigerator damper and refrigerator

Abstract

The application provides a refrigerator air door and a refrigerator, wherein the air door comprises: an air door frame; the air door frame surrounds an air passage for air supply; an air door plate is arranged in the air passage; one end of the air door plate is hinged to the air door frame, and the air door plate can rotate relative to the air door frame to an open state or a closed state; in the open state, the air passage is exposed and communicates with the environments on both sides of the air passage; in the closed state, the air door plate blocks the air passage; a driving mechanism is arranged on one side of the air door frame and connected with the air door plate, and is used for providing a driving torque for the rotation of the air door plate relative to the air door frame; a magnet is arranged on the air door plate; and a magnetic field detector is arranged on one side of the air door frame and is used for detecting the magnetic field change generated by the movement of the magnet. The refrigerator air door and the refrigerator provided by the application do not have the problem of low-temperature failure, can realize timely and rapid detection, and reduce the probability of the occurrence of the problem of excessive refrigeration or no refrigeration.
