The utility model discloses refrigerator, include the box 100 door body 200 with connect box 100 and door body 200 hinge 300, wherein hinge 300 includes guide block 330 rotatory piece 340 with elastic component 350, when door body 200 was opened, guide block 330 with the elastic component takes place to rotate relatively guide block 330 with set up on the rotatory piece 340 spacing portion 332 with spacing groove 341 when door body 200 was opened to a certain extent, spacing portion 332 with spacing groove 341 forms the cooperation, prevents door body 200 continues the motion, door body 200 is in the state of hovering. In this state, the user does not need to hold the door body 200 by hands, and can take and place articles with both hands. When the door body 200 is closed, a user applies an external force to the door body 200 to disengage the limiting portion 332 from the limiting groove 341, and the elastic force of the elastic member 350 drives the rotating block 340 to reset, so that the door body 200 is automatically closed.

In some embodiments, referring to fig. 12, the guide portion 331 protrudes upward on the upper surface of the guide block 330 in the axial direction of the hinge shaft 320, and the limiting portion 332 is disposed at the top of the guide portion 331. The guiding portion 331 is in the shape of a cam protruding upward, and the limiting portion 332 can be provided with a limiting member alone, or in the manner of this embodiment: the top of the guide portion 331 forms the stopper portion 332.

Referring to fig. 9 to 10, the rotation block 340 is disposed above the guide block 330, a cam portion 342 protruding downward along the axial direction of the hinge shaft 320 is disposed at the bottom of the rotation block 340, the cam portion 342 is adapted to the shape of the guide portion 331, and the limiting groove 341 recessed upward is formed at the bottom of the cam portion 342. The rotating block 340 is in the shape of a cam protruding downward, when the limiting groove 341 is matched with the limiting part 332, the top of the limiting part 332 is clamped in the limiting groove 341, and the rotating block 340 and the guiding block 330 cannot move relatively.

When the door body 200 is opened, the cam portion 342 and the guide portion 331 move relatively, so that the guide block 330 pushes up the rotating block 340 and compresses the elastic member 350 until the limiting portion 332 enters the limiting groove 341, and the elastic force of the elastic member 350 causes the limiting portion 332 to be clamped in the limiting groove 341. At this time, the relative movement between the rotation block 340 and the guide block 330 is stopped, and the door 200 is in a hovering state.

When the door body 200 is closed, the limiting portion 332 is disengaged from the limiting groove 341, and the elastic force of the elastic member 350 drives the cam portion 342 to move downward, so that the rotating block 340 is reset. When the limiting portion 332, that is, the top of the guiding portion 331 in this embodiment, leaves the limiting groove 341, the limiting portion 332 is disengaged from the limiting groove 341. Because the elastic member 350 is in a compressed state, the elastic member 350 continuously provides the elastic force for the rotating block 340 to drive the rotating block 340 to reset, and after the rotating block 340 is reset, the door body 200 is also in a closed state.
