Detailed Description
Fig. 1 is a schematic configuration view of a door body hinge device according to an embodiment of the present invention. As shown in fig. 1, and referring to fig. 2 to 4, an embodiment of the present invention provides a door hinge device 300 for a refrigerator. The door hinge device 300 may generally include a base 20 and a door mount 30, the base 20 being configured to mount to the cabinet 100 of the refrigerator, and the door mount 30 being configured to mount the door 200 of the refrigerator. Specifically, the door hinge device 300 in this embodiment further includes a triangular arc 40 and a square groove 50, and the triangular arc 40 is engaged with the square groove 50 and moves in the square groove 50. One of the arc triangle 40 and the square groove 50 is installed at the base 20, and the other is fixedly installed at the door installation seat 30.
In the door body hinge device 300 according to the embodiment of the present invention, the side lengths of the arc triangle 40 and the square groove 50 are equal, and the three vertexes of the arc triangle 40 all move along the edge of the square groove 50, so that the axis of the arc triangle 40 can move and can also rotate when the arc triangle 40 moves. Further, after the arc triangle 40 is mounted on the door mounting seat 30, the door body 200 is fixedly mounted on the door mounting seat 30, and the rotating shaft of the structure of the door body 200 is coaxial with the arc triangle 40, the rotating shaft of the structure of the door body 200 can rotate around the axis of the square groove 50 and can also rotate.
Further, as shown in fig. 4, the motion trajectory of the rotation axis of the door body 200 may be L1, so that each point or line on the door body 200 may have a compound motion, for example, a seal tip point a line of the door seal may be made to move to a side away from the box 100 while rotating around the rotation axis of the door body 200 when the door body 200 is opened, and the motion trajectory may be L2, so that the motion trajectory of the door seal changes from an arc shape to a trajectory having an approximate straight line segment, thereby avoiding interference with the inner container of the box 100, that is, avoiding interference between the door seal and the inner container of the box 100 during the door closing process, reducing interference of the door seal, avoiding squeezing the door seal, and reducing the thickness of the door seal.
Further, the edge B line of the door side can move along the track L3, and the edge C line of the door body 200 at the vertical beam position can move along the track L4 when the refrigerator is a side-by-side combination door. That is, the motion trajectory of the side edge of the door body 200 is changed from the original arc line around the fixed axis to the trajectory having an approximate straight line segment, thereby avoiding the collision between the side edge and the wall. If the refrigerator is a side-by-side refrigerator, the motion track of the ridge line at the middle vertical beam part is changed from the original arc line around the fixed axis into a track with an approximate straight line section, so that the side edge is prevented from colliding with the other side door frame.
In some embodiments of the present invention, the door mount 30 includes a door mounting shaft 31, and the door mounting shaft 31 is coaxially disposed with the square slot 50 or the arc triangle 40 mounted to the door mount 30. For example, the base 20 includes a hinge plate 21, and the square groove 50 is installed on the hinge plate 21, so that the arc triangle 40 is fixedly installed on the door installation seat 30, and the arc triangle 40 is coaxially installed with the door installation shaft 31. The base 20 further has a vertical plate 23 installed at one side edge of the hinge plate 21, and the vertical plate 23 is used to install the base 20 to the cabinet 100.
Further, the door mount 30 further includes a coupling plate 32 and a stopper hook 33; one end of the connecting plate 32 is connected to the arc triangle 40 and the door mounting shaft 31, and the other end is connected to the stopper hook 33. The hinge plate 21 has a stopper protrusion configured to be inserted into the stopper hook 33 when the door 200 closes the cabinet 100, to lock the door 200 and the cabinet 100.
In order to fix the door body 200 to the door mounting seat 30, the connecting plate 32 is provided with a retaining hole 34. The door body 200 has a shaft hole 210 mounted to the door mounting shaft 31 and a boss 220 mounted to the retention hole 34 to prevent the door body 200 from rotating relative to the door mounting seat 30.
The embodiment of the invention also provides a refrigerator, which comprises a refrigerator body 100, a door body 200 and the door body hinge device 300 in any embodiment, wherein the base 20 is installed on the refrigerator body 100, and the door body 200 is installed on the door installation seat 30.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
