Definitions

  • the present invention relates to a refrigerator, in particular, to a refrigerator having a pair of side-by-side doors.
  • JP2007-024462 discloses a refrigerator having a pair of French doors, and in which a magnetic field sensor and a magnet are arranged on a corresponding sidewall of the corresponding door respectively to detect whether at least one of the doors is open.
  • a longitudinal sidewall of the door of the refrigerator is formed by an extruded side cover or by a portion bent rearward from a metal sheet that forms a front wall of the refrigerator door, installing the magnetic field sensor or magnet on these components significantly increases difficulty and complexity of manufacturing of the refrigerator doors.
  • An object of the present invention is to provide a refrigerator that is easier to manufacture.
  • An aspect of the present invention relates to a refrigerator, which includes a pair of side-by-side doors.
  • One of the doors is provided with a magnetic sensitive unit and the other door of the doors is provided with a magnet cooperating with the magnetic sensitive unit;
  • each of the doors includes an end cover which includes a main body part which forms a horizontal sidewall of the door;
  • the refrigerator is characterized in that each of the end covers includes a side cover part which is connected to one end of the main body part and extends longitudinally, the pair of side cover parts face each other when the pair of doors are closed, and the magnetic sensitive unit and the magnet are connected to a corresponding side cover part respectively.
  • the horizontal sidewall defined by the main body part may be generally horizontal and may also have steps for being provided with multiple (for example, two) walls (which can be horizontal) at different heights.
  • the end cover may be an upper end cover arranged on the top of the door, or a lower end cover arranged at the bottom of the door.
  • the magnetic sensitive unit can sense the existence of a magnet field or of the magnet field intensity (within an effective range), and may include, for example, a magneto-resistive sensor, a Hall sensor, or a reed switch.
  • At least one of the magnetic sensitive unit and the magnet has at least a part thereof extends into a corresponding door through a through hole in a corresponding side cover part.
  • the magnetic sensitive unit and/or the magnet being connected to the corresponding side cover parts in this way can make it is possible that at least a part of the magnetic sensitive unit and/or the magnet can be connected to the side cover parts after a foaming procedure of the doors, so that when the magnetic sensitive unit and/or the magnet is damaged, it is possible to replace at least a part of the magnetic sensitive unit and/or the magnet without damaging the doors.
  • At least one of the magnetic sensitive unit and the magnet is attached to an inner side of a corresponding side cover part.
  • the magnetic sensitive unit and/or the magnet being connected to the side cover parts in this way is advantageous for maintaining integrity of appearance of the side cover parts. This solution is particularly beneficial to the magnet that is hardly damaged and does not need replacement normally.
  • each of the end cover is provided with a corresponding accommodating cavity for accommodating a corresponding one of the magnetic sensitive unit and the magnet, and at least a part of a border of the accommodating cavities is defined by a corresponding side cover part.
  • the refrigerator includes a protruding wall that is connected to the inner side of the side cover part and located bellow the main body part, and the protruding wall defines at least a part of a border of the accommodating cavity for accommodating the magnetic sensitive unit or the magnet.
