Definitions

  • the present invention relates to a refrigeration appliance with two doors, and in particular, to a household refrigeration appliance, for example, a refrigerator.
  • WO2007/115868 discloses a refrigerating device, including a main body, a pair of opposing doors connected at opposite sides of the body, and a beam rotatably connected onto a first door.
  • the beam can be pivoted by a guiding projection which can be displaced in a guiding groove, between an extending position when the first door is closed and a retraction position when the first door is open, where at the position when the first door is closed, one edge of the second door, which is opposite the fixed edge of the second door, is applied to the beam, and at the position when the first door is opened, the beam can pass to the closed second door.
  • the guiding projection can be displaced with respect to the first door along a direction of a pivotable axis of the first door. Therefore, it may be ensured that the top of the guiding projection contacts the base of the guiding groove, so that no air can pass through the guiding projection into the inside of the refrigerating device.
  • the beam may be rotated to the retraction position through movement of the guiding projection in the guiding groove.
  • the designer connects the first door with a hinge unit of the beam with reasonable design, for example, use of means such as cam or torsion spring, which may exert a certain holding force on the beam at the retraction position to prevent arbitrary rotation of the beam, so that the beam may be more reliably automatically held at the retraction position.
  • means such as cam or torsion spring, which may exert a certain holding force on the beam at the retraction position to prevent arbitrary rotation of the beam, so that the beam may be more reliably automatically held at the retraction position.
  • the user still can easily rotate the beam manually to the extending position.
  • damage may be caused to the refrigeration appliance if the user forcibly closes the first door.
  • One objective of the present invention is to overcome the above at least one technical problem, so as to provide a refrigeration appliance helping to prolong the service life.
  • the refrigeration appliance includes a main body, having a storage chamber with a front opening; a first door and a second door, the first door and the second door each including a first end fixed to an opposite side of the front opening and a second end opposite to the first end; and a beam, pivotally connected to the second end of the first door and capable of being rotated between a retraction position and an extending position around a rotation axis, where when the first door is closed, the first door is located at the extending position; and when the first door is opened, the beam is capable of being rotated from the extending position to the retraction position; the refrigeration appliance is characterized in that, the refrigeration appliance includes a locking unit for locking the beam at the retraction position when the first door is in an open state.
  • the beam is locked at the retraction position and is incapable of being rotated, the beam still can be held at the retraction position even if the user forcibly pulls the beam, this fundamentally avoids the situation that the first door is closed when the beam is at the retraction position, so that the service life of the refrigeration appliance could be prolonged.
  • the locking unit in a process of closing the first door, releases the beam from a locked state at the retraction position.
  • the locking unit can automatically release the beam from the locked state of being incapable of being rotated in a process that the user normally closes the first door, it is convenient to use.
  • the refrigeration appliance includes a guiding mechanism for driving the beam to be rotated between the retraction position and the extending position, where the locking unit is disposed to release, in a process of closing the first door, the beam from the locked state at the retraction position before the guiding mechanism generates a force impelling the beam to be rotated from the retraction position to the extending position.
  • This not only facilitates the first door to smoothly close and is easy for user operation, but also helps to avoid that the guiding mechanism is damaged in the process of closing the first door.
  • the locking unit is disposed on the main body, according to a particularly exemplary embodiment of the present invention, the locking unit is located on the beam.
  • the locking unit is pivotally connected to the beam and the first door, where the hinge unit cooperates to lock the beam at the retraction position.
  • the hinge unit includes a fixed member incapable of being rotated with respect to the first door and a rotatable member capable of being rotated together with the beam with respect to the first door

  • the receiving portion for example, may be a hole, a slot or other facility receiving other components.
  • the stopping portion is plugged into the fixed member in a direction perpendicular to the rotation axis.
  • the locking unit is aligned with the fixed member to achieve a plug-in connection.
  • the beam is locked and is incapable of being rotated.
  • the locking unit includes a pressuring portion for imposing a force on the stopping portion to enable the stopping portion to be plugged into the fixed member.
  • the locking unit includes an unlocking portion
  • the main body includes a drive member fit with the unlocking portion, and in the process of closing the first door, the drive member drives the unlocking portion to release the beam from the locked state at the retraction position.
  • the drive member is located at an edge of the front opening, so that, in the process of closing the first door, the drive member can meet the unlocking portion as soon as possible to release the beam from the locked state.

Therefore, whether the stopping portion 21 is aligned with the hole 48 or not, the stopping portion 21 can reliably maintain a detached state with the hole 48.
  • the guiding mechanism 7 When the left door 4 is opened, the guiding mechanism 7 enables the beam 6 to be rotated from the extending position to the retraction position. After the beam 6 reaches the retraction position, the unlocking portion 23 is detached from the drive member 30. With the action of the pressuring member 22, the stopping portion 21 is inserted into the hole 48.
