Referring to fig. 1 to 4, an embodiment of the present disclosure provides a refrigerator including a case 10 and a door 20, and further including a door closing structure and a driving structure 40, the door closing structure being provided to the door 20, including a lever assembly 30 extending toward the case 10, the lever assembly 30 extending into a receiving groove 110 of the case 10, the lever assembly 30 being swingable within the receiving groove 110 and being movable along a depth direction of the receiving groove 110; the driving structure 40 is disposed on the door body 20, connected to the door closing structure, and configured to drive the lever assembly 30 to swing relative to the door body 20; when the included angle between the door body 20 and the box body 10 is smaller than or equal to a preset angle, the driving structure 40 drives the rod assembly 30 to swing relative to the door body 20 so as to reduce the included angle between the door body 20 and the rod assembly 30, and under the limitation of the accommodating groove 110, the rod assembly 30 abuts against the side wall of the accommodating groove 110 and drives the door body 20 to swing towards the closing direction; when the included angle between the door 20 and the case 10 is greater than a preset angle, the driving structure 40 is separated from the lever assembly 30.

The refrigerator body 10 has a receiving space inside for receiving articles, and the receiving space may include a refrigerating space and a freezing space. The front side of the case 10 is opened, and the door 20 is rotatably connected with the case 10, and can be opened to allow the accommodating space to communicate with the outside, or closed to allow the accommodating space to be closed, so as to store the inside articles. The refrigerator may be a single door refrigerator or a double door refrigerator.

The refrigerator is provided with a door closing structure capable of automatically closing the door body 20 when an included angle between the door body 20 and the cabinet 10 is small, for example, smaller than or equal to a preset angle. Therefore, the refrigerating effect of the refrigerator can be maintained, and the storage of articles in the refrigerator is facilitated. The door closing structure is disposed on the door body 20 and may be disposed on the top of the door body 20 and/or the bottom of the door body 20, so that a force can be generated on the case 10 from the top of the door body 20 and/or the bottom of the door body 20. The preset angle may be 35 deg. to 55 deg., for example, the preset angle is 40 deg..

As shown in fig. 3, the case 10 is provided with a receiving groove 110, and the position of the receiving groove 110 is set corresponding to the extended end of the lever assembly 30. Alternatively, the lever assembly 30 is perpendicular to the front side of the cabinet 10 and protrudes into the receiving groove 110 in a state where the door 20 of the refrigerator is closed. Thus, when the driving structure 40 drives the lever assembly 30 to swing, the lever assembly 30 can abut against the side wall of the accommodating groove 110 to drive the door body 20 to swing towards the closing direction.

The depth of the receiving groove 110 is a length of the receiving groove 110 extending from the front side to the rear side of the case 10. The front side of the case 10 means a side of the case 10 facing the user, and the rear side of the case 10 means a side of the case 10 facing away from the user. In a state where the door body 20 is closed, the length of the portion of the lever assembly 30 protruding into the receiving groove 110 is smaller than the depth of the receiving groove 110. In this way, the receiving groove 110 has enough space for the lever assembly 30 to be inserted so that the door body 20 can be closed. The portion of the lever assembly 30 extending into the receiving groove 110 gradually increases when the door body 20 is closed, and the portion of the lever assembly 30 extending into the receiving groove 110 gradually decreases when the door body 20 is opened. The lever assembly 30 remains partially within the receiving groove 110 when the door body 20 is opened to a maximum angle, and does not escape from the receiving groove 110.

The width of the receiving groove 110 refers to the length of the receiving groove 110 in the left-right direction, and "left" and "right" refer to the left and right sides when the user faces the case 10. The width of holding tank 110 is greater than the width of pole subassembly 30, makes pole subassembly 30 can stretch into in holding tank 110 on the one hand, and on the other hand pole subassembly 30 can carry out the swing of a small margin in holding tank 110 to make the door body 20 in closing the in-process pole subassembly 30 have certain removal space in holding tank 110, avoid producing too much restriction to pole subassembly 30 and influence the closing of door body 20.

Optionally, the rotation axis of the door 20 is located at the left side of the door 20, and when the door 20 is opened, the right side of the door 20 is turned outwards relative to the rotation axis to open the door 20, so that the lever assembly 30 abuts against the left side wall of the accommodating groove 110 when the door 20 is in the closed state, and when the door 20 is opened to the maximum angle, the lever assembly 30 abuts against the right side wall of the accommodating groove 110. The lever assembly 30 moves from the left side wall to the right side wall of the receiving groove 110 when the door body 20 moves from the closed position to the maximum opening angle.

Similarly, if the rotation axis of the door 20 is located at the right side of the door 20, the left side of the door 20 is turned outwards when the door 20 is opened, so that the door 20 is opened, the above-mentioned lever assembly 30 is exchanged with the position relationship of the left and right side walls of the receiving groove 110 during the movement.

The driving structure 40 is disposed on the door body 20 and is capable of driving the door closing structure to move, specifically, the driving rod assembly 30 swings relative to the door body 20. Since the lever assembly 30 extends from the door body 20 toward the case body 10, a certain angle is formed between the lever assembly 30 and the door body 20, and when the driving structure 40 drives the door closing structure, the lever assembly 30 swings with respect to the door body 20 in a direction in which the angle is reduced. The door closing structure stretches into the accommodating groove 110, can swing in the accommodating groove 110 by a small extent, takes the rotation shaft of the door body 20 as an example on the right side of the door body 20 in the movement process, when the included angle between the door closing structure and the door body 20 is reduced just at the beginning, the door closing structure swings left in the accommodating groove 110, when the included angle is reduced to a certain extent, the door closing structure abuts against the left side wall of the accommodating groove 110 and cannot swing continuously, a reaction force is generated on the door body 20, and the door body 20 moves towards the closing direction by the reaction force, so that the included angle between the door body 20 and the rod assembly 30 is further reduced. In the opened state of the door body 20, the rod assembly 30 forms an obtuse angle with the door body 20, and when the door body 20 is completely closed, the rod assembly 30 forms an angle of 90 ° with the door body 20.
