Definitions

  • the present invention relates to the field of household appliances and in particular to a door closer and a refrigerator having the same.
  • FIG. 1 and FIG. 2 show a hinge assembly structure in the prior art.
  • the hinge assembly includes a hinge plate 11 and an adapter 12 rotatably connected to the hinge plate 11.
  • the hinge plate 11 is fixed on a cabinet of the refrigerator, and a door body of the refrigerator is fixed on the adapter 12, thereby achieving the rotatably connection of the cabinet and the door body.
  • a hook-shaped stop 120 is generally formed on the adapter 12, and a protrusion 110 corresponding to the stop 120 is formed on the hinge plate 11; referring to FIG. 2 , based on the above structure, after the door body of the refrigerator is closed, the hook of the stop 120 can catch the protrusion 110, thereby keeping the closed state of the door body.
  • this technical means of keeping the door body closed has the following disadvantages:
  • the stop 120 needs to be deformed during the door body closing process to catch the protrusion 110 of the hinge plate 11. If the size of the hook of the stop 120 is too small, after the door body is closed, loss fitting might occur between the stop 120 and the protrusion 110 and cause the door body not to be closed tightly; if the size of the hook of the stop 120 is too large, the stop 120 needs to be deformed greatly when the door body is closed so that the stop 120 wears seriously and even is directly broken during use of the refrigerator.
  • the present invention aims to at least solve one of the technical problems existing in the prior art.
  • the present invention provides a door closer whose specific design manner is as follows.
  • a door closer comprises a hinge plate, a hinge shaft disposed on the hinge plate, and an adapter disposed rotatably around the hinge shaft.
  • the door closer further comprises a cam disposed on the hinge shaft, a peripheral side of the cam retracts inward the cam to form a first recessed region, an elastic mechanism is provided in the adapter, and the elastic mechanism has an abutting end for elastically abutting against the periphery of the cam; during the turning of the adapter, the abutting end moves relative to the periphery of the cam, and when the adapter turns to the side of the first recessed region of the cam, the abutting end enters the first recessed region to lock a positional relationship between the adapter and the hinge plate.
  • the adapter is a housing
  • the housing comprises a top plate and a bottom plate which are arranged opposite to each other
  • a receiving cavity for receiving the elastic mechanism is formed between the top plate and the bottom plate
  • the top plate and bottom plate extend towards the hinge shaft to form a top plate extension and a bottom plate extension located above and below the cam, respectively

  • the elastic mechanism comprises a spring and an elastic force release portion
  • the spring is compressed and disposed in the receiving cavity in a radial direction of the hinge shaft, and an end of the spring away from the hinge shaft is fixedly disposed relative to the housing;
  • the elastic force release portion is located between the spring and the cam to apply the elastic force of the spring to the periphery of the cam, and the abutting end is formed at an end of the elastic force release portion adjacent to the hinge shaft.
  • the elastic force release portion comprises a bracket and a roller
  • the bracket is disposed abutting against the spring
  • a bracket tail extending into the spring is formed on a side of the bracket adjacent to spring
  • the roller is rotatably disposed at the end of the bracket away from the spring and constitutes the abutting end
  • an axis of rotation of the roller is parallel to an axis of rotation of the adapter.
  • top plate and the bottom plate are formed with elongated guide holes in a radial direction of the hinge shaft, and both ends of the roller respectively have guide fitting portions which extend into the guide holes to limit the movement of the roller in the radial direction of the hinge shaft.

  • the surface of the periphery of the cam on which the abutting end moves is further formed with at least one third recessed region which is located between the first recessed region and the second recessed region; when the adapter turns to the third recessed region of the cam, the abutting end enters the third recessed region to lock a positional relationship between the adapter and the hinge plate.
  • the hinge shaft comprises a first shaft body and a second shaft body
  • the first shaft body is fixed on the hinge plate and a fitting hole is formed therein in a height direction
  • the second shaft body is rod-shaped and its lower end is non-rotatably fitted in the fitting hole.
