Abstract: An ice tray assembly and refrigerator having the same are disclosed, by which pieces of ice stored in a plurality of ice trays can be simultaneously discharged by a single motion without interfering with each other. The present invention includes a plurality of ice trays vertically provided within a case, a plurality of the ice trays connected to one another by an interoperating means to be simultaneously rotated and a driving means for rotating a plurality of the ice trays by being connected thereto.

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.

Abstract: The present invention relates to gaskets (120), and more particularly, to a gasket (120) which enables, not only to seal a gap between two components, but also easy attachment/detachment of the two components; and a refrigerator therewith. The gasket (120) includes a case (124) having a sealing member (122) attachable/detachable to/from a predetermined thing for sealing a gap when the sealing member (122) is attached, a close contact piece (126) for making close contact to other thing, and a plurality of supporting pieces (130, 132) connected between the close contact piece (126) and the case (124) so that one side of an attached surface of the sealing member (122) is detached from the predetermined thing at first if the other thing is pulled forward.

Abstract: A lower limit of a heating factor for heating control of an oxygen sensor is adjusted on the basis of the heating factor, a P-jump delay time calculated based on an output voltage of the oxygen sensor, and a diagnosis index of the oxygen sensor, and thereby an engine may be stably controlled even if the oxygen sensor is aged.
