Definitions

  • the present invention relates to a refrigeration appliance comprising two doors, in particular a domestic refrigeration appliance, such as a refrigerator.
  • WO2007/115868 discloses a refrigeration device, comprising a body, a pair of side-by-side doors connected to opposite sides of the body and a bar rotatably connected on a first door.
  • the bar can be pivoted between an extension position and a retraction position by a guiding projection capable of displacing in a guiding groove, wherein the bar is in the extension position when the first door is closed, and the bar is in the retraction position when the door is opened.
  • a guiding projection capable of displacing in a guiding groove
  • the guiding projection can displace with respect to the first door in a direction of a pivot axis of the first door. Thus, it may be ensured that a top end of the guiding projection contact with a bottom of the guiding groove such that no air can enter an interior of the refrigeration device through the guiding projection.
  • the bar may be rotated into the retraction position via a movement of the guiding projection within the guiding groove under cooperation of the guiding projection with the guiding groove, there is such a possibility in which the bar may be unintentionally rotated into the extension position by a user.
  • the guiding projection may be rebounded due to intensive collision of the guiding projection with a groove wall defining the guiding groove, which may lead to damage of the refrigeration appliance.
  • one aspect of the present invention relates to a refrigeration appliance, comprising: a body, a front end of which has an opening; a first door and a second door each comprising a first edge and a second edge opposite to said first edge, the first edges of the first door and the second door being fixed to opposite sides of said opening respectively; a bar fixed to the second edge of said first door and being able to be pivoted between a retraction position and an extension position, the bar being in the extension position when the first door is closed, wherein said bar can pass through the closed second door when the bar is in said retraction position; and a guiding mechanism for guiding said bar to rotate, said guiding mechanism comprising a first guiding member disposed on said bar and a second guiding member disposed on an edge of said opening, wherein one of said first guiding member and said second guiding member comprises a guiding projection, the other of said first guiding member and said second guiding member comprises a guiding groove, and said guiding projection can be moved within said guiding groove to cause said
  • first guiding member and the second guiding member do not intensively collide with each other so as to cause damage when the first door is closed in the case that the bar is in the extension position, thereby it being beneficial to improve useful life of the refrigeration appliance.
  • said bar and said first door define an angle therebetween, which keeps constant when said first door is closed in the case that said bar is in the extension position.
  • said guiding projection is linearly moved with respect to said first door when said first door is closed in the case that said bar is in the extension position.
  • said guiding projection extends over a groove wall of said guiding groove facing said guiding projection so as to enter said guiding groove.
  • At least one of said guiding projection and said groove wall can be displaced with respect to said first door along a direction of a pivot axis of said first door.
  • at least one of the guiding projection and the groove wall can be moved away from each other when the guiding projection and the groove wall contact with each other. Further, this benefits return of the displaceable member to an initial position to prevent the guiding projection within the groove wall from moving away from the groove wall after the contact between the guiding projection and the groove wall has been released.
  • a tip face of at least one of said guiding projection and said groove wall has a guiding slope, and a height of said guiding projection and/or said groove wall at respective guiding slope become smaller while getting closer to each other.
  • the entire tip face of at least one of said guiding projection and said groove wall forms said guiding slope. This may cause the guiding projection to more easily extend over the groove wall to enter the guiding groove.
  • said guiding slope has a plurality of protuberances. This benefits reduction of a friction force between the guiding projection and the groove wall.
  • said protuberances comprise ribs extending along an inclination direction of said guiding slope.
  • said guiding projection is rotated along the guiding groove and causes said bar to rotate into the retraction position, which cause the bar to automatically arrive in the retraction position after the first door is opened, thereby, in a normal condition, it is possible to close the first door by rotating the guiding projection along the guiding groove.
