The present invention discloses an automatic door opening device and a refrigerator having the same. The automatic door opening device comprises a base, a driving source member, two mechanical clutch gear sets and two pushing members, wherein the mechanical clutch gear set comprises a mechanical master gear, a mechanical slave gear, and a mechanical clutch member; in an initial state, the mechanical master gear is partially meshed with the mechanical clutch member which is separated from the mechanical slave gear; in a door body opening process, the mechanical master gear drives the mechanical slave gear to be in a transmission state; and after the door body is opened, the mechanical clutch gear set is recovered to an initial connection state.
