Abstract
Disclosed are a water tank and a refrigerator having the same. The water tank includes a tank main body provided with a water storage space formed therein and a discharge hole; a tank cover connected to the tank main body for opening and closing the water storage space; a valve movably installed in the tank main body for opening and closing the discharge hole; and a valve driving unit moving the valve using magnetic force so as to cause the valve to open and close the discharge hole. The water tank is opened and closed by the magnetic force of magnets and the restoring force of elastic members, and thus it is possible to prevent water stored in the water tank from leaking out in a process of attaching or detaching the water tank to or from the rear surface of a door or a refrigerator.
