The second door 30 of the present embodiment can directly cooperate with the stopper assembly 224 via the hinge shaft 225, so that the second door 30 can rotate and can be limited within the first predetermined angle range.

FIG. 7 is a schematic exploded view of a stop assembly of the first lower hinge according to one embodiment of the present invention. As a specific embodiment of the present invention, as shown in fig. 7, the stopping assembly 224 of the present embodiment may include a housing 226, a rotating member 227, and a stopper 228. The housing 226 is disposed at the second shaft hole position of the second door body 30. The rotary member 227 is disposed in the housing 226, and the rotary member 227 is engaged with the hinge shaft 225 to rotate in synchronization with the hinge shaft 225. The stopper 228 is disposed in the housing 226 at a side of one end of the rotary member 227 in the axial direction, and is in anti-rotation connection with the housing 226, for rotating the rotary member 227 relative to the stopper 228 within a first predetermined angle range when the rotary member 227 rotates.

In this embodiment, the connecting member 221 is plate-shaped, and is disposed horizontally when the refrigerator 100 is placed on a flat bottom, and one end of the connecting member is connected to the bottom surface of the first door 20 of the refrigerator 100 through a fastening member. The hinge shaft 225 at the other end is located on the upper side of the connection member 221 and extends vertically upward. The second shaft hole may also be vertically disposed and disposed at an inner position of the second door body 30.

In this embodiment, the rotating member 227 is located between the connecting member 221 and the stopper 228.

Specifically, the housing 226 may be a hollow cylindrical structure. More specifically, the housing 226 may have a cylindrical hollow structure inside and a cubic structure outside. The rotating member 227 and the stop member 228 cooperate with the hollow interior of the housing 226 to form a cylindrical outer side. The upper end of the housing 226 may also include a cap 247, the cap 247 being secured to the housing 226 by a latch 248.

Specifically, the rotating member 227 may be a hollow cylinder structure, and the outer circumference thereof is engaged with the inner wall of the housing 226. The bottom end surface of the rotary member 227 is a plane structure, and the end surface is formed with a through hole 241 which is non-circular and is penetrated through the hollow structure of the housing 226, the outer periphery of the hinge shaft 225 is adapted to the structure of the through hole 241, and when the hinge shaft 225 rotates relative to the second door body 30, the hinge shaft 225 drives the rotary member 227 to rotate. Specifically, the through hole 241 may have a rectangular structure, but may have other structures such as a square structure, a pentagonal structure, and a hexagonal structure. The cross section of the hinge shaft 225 is adapted to the structure of the through hole 241, and taking the through hole 241 as a rectangular structure and the hinge shaft 225 as a rectangular structure as an example, when the hinge shaft 225 is inserted into the through hole 241, the hinge shaft 225 can rotate together with the rotary member 227 because the hinge shaft 225 cannot rotate relative to the through hole 241.

In addition, the outer circumference of the stopper 228 may have a circular shape, the stopper 228 may be disposed at an upper end of the rotary member 227, the stopper 228 may be rotatably coupled to the second door 30, and the rotary member 227 and the hinge shaft 225 may be rotated within a first predetermined angle range with respect to the second door 30 by the stopper 228. Specifically, the first preset angle range may be 0 to 175 °. That is, the first door 20 can rotate within a range of 0 to 175 ° with respect to the second door 30, and when the second door 30 continues to rotate, the rotation is stopped by the stopper 228. Certainly, the first preset angle range may be designed according to actual situations, and generally, the opening angle of the second door 30 should be at least 120 degrees, and the maximum opening angle should be 175 degrees, and too small or too large is not beneficial to the use of the door of the refrigerator 100, which affects the use experience of the user.

As a specific example of the present invention, the rotating member 227 of the present embodiment is provided with a protruding portion 242 at an end near the stopper 228. The stopper 228 is provided with a groove portion 243 at an end close to the rotary member 227. Wherein, the protrusion portion 242 and the recessed portion 243 are engaged, so that the rotating member 227 rotates relative to the stopping member 228 within a first preset angle range.

Specifically, the boss portion 242 and the recessed portion 243 may be both two, and the positions and the sizes of the arrangement of the boss portion 242 and the recessed portion 243 may be designed as needed according to the angle. When the protrusion 242 and the groove 243 come close to each other, the first door 20 can rotate relative to the second door 30, and when the second door 30 rotates until the protrusion 242 and the groove 243 abut against each other, the second door 30 cannot rotate relative to the first door 20 any more.

As a specific embodiment of the present invention, the stopper 228 of the present embodiment is provided at an outer circumferential surface thereof with a projection 244 projecting in a radial direction of the stopper 228. The inner wall of the housing 226 is provided with a guide groove (not shown) engaged with the projection 244, the guide groove extending in a direction parallel to the axis of the stopper 228, so that the stopper 228 can be translated in the direction parallel to the axis under the guide of the guide groove.

The number of the protrusions 244 in this embodiment may be at least one, and preferably two, and are symmetrically disposed at the outer circumferential position of the stopper 228. And the number of guide slots corresponds to the number of projections 244. Since the guide groove extends in a direction parallel to the axis, the stopper 228 cannot rotate with the housing 226 when the rotating member rotates due to the guide groove.

As a specific embodiment of the present invention, the groove portion 243 of the stopper 228 of the present embodiment includes a slope 245, and the slope 245 extends from the bottom end of the groove portion 243 to a position close to the opening. Specifically, the number of recessed portions 243 is the same as the number of inclined surfaces 245.

The door body assembly 200 may further include a spring 246, the spring 246 being abutted between an end of the stopper 228 opposite to the rotary 227 and an inner wall of the housing 226, the spring 246 being configured to be compressed when the door opening force causes the projection 244 of the rotary 227 to contact the inclined surface 245 of the stopper 228, and to provide an elastic force for urging the stopper 228 to move downward when the door opening force is removed, so that the rotary 227 reversely rotates until the protruding portion 242 abuts against the bottom end of the groove portion 243.

Specifically, when the second door 30 is closed at the first door 20, the protruding portion 242 of the rotating member 227 is located at the bottom of the groove portion 243 of the stopper 228, when the second door 30 is gradually rotated and opened by an external force, the protruding portion 242 is continuously close to the inclined surface 245 and gradually moves from the bottom end of the groove portion 243 to the opening position along the inclined surface 245, the stopper 228 is pushed to translate along the guide groove to move away from the rotating member 227, and when the external force is removed, the stopper 228 pushes the rotating member 227 to rotate reversely until the protruding portion 242 abuts against the bottom end of the groove portion 243 under the action of the spring 246.

The structure of the inclined plane 245 of the stopper 228 of the door assembly 200 of the present embodiment not only enables the second door 30 of the refrigerator 100 to be stopped by the stopper 228 when being opened, but also can provide a reaction force to the second door 30 when the second door 30 is opened to a certain position under the action of the inclined plane 245, so as to prevent the second door 30 from rotating under the action of inertia or rotating under the action of an external force until the side walls of the protruding portion 242 and the groove portion 243 directly collide with each other to damage the protruding portion 242, and prolong the service life of the door assembly 200. In addition, when the second door 30 rotates until the protruding portion 242 contacts the side wall of the groove portion 243 and the force applied to the second door 30 is released, the inclined surface 245 of the groove portion 243 pushes the protruding portion 242 and then the stopper 228 drives the second door 30 to rotate under the elastic force of the spring 246, so that the second door 30 has a tendency of rotating, which is beneficial to closing the second door 30.

As a specific embodiment of the present invention, the rotating member 227 of the present embodiment is located between the connecting member 221 and the stopper 228. A washer 249 may also be included in the housing 226, the washer 249 being located between the bottom of the rotating member 227 and the inner wall of the bottom of the housing 226.

The washer 249 in this embodiment may be of a circular configuration and disposed inside the housing 226, and the rotating member 227 is blocked from the inner wall of the bottom of the housing 226 by the washer 249. The washer 249 in this embodiment can make the rotation between the rotary member 227 and the housing 226 smoother.

Specifically, the second lower hinge 230 of the present embodiment includes a fixing plate 231, one end of the fixing plate 231 is connected to the box 10, the other end is provided with a rotating shaft 232, and a rotating shaft 232 hole for the rotating shaft 232 to penetrate is formed in the first door 20. Specifically, the fixing plate 231 is disposed below the connection member 221 in parallel with the connection member 221. The connecting piece 221 is provided with a stop block 223 at a side close to the fixing plate 231, and since the connecting piece 221 is fixedly connected with the first door body 20, the connecting piece 221 rotates along with the rotation of the first door body 20. Similarly, the stopper 223 rotates along with the rotation of the first door body 20. The fixing plate 231 is configured to allow the stopper block 223 to move when the stopper block 223 rotates with the first door body 20 relative to the cabinet 10 within a second preset angle range, and to prevent the stopper block 223 from moving when the stopper block 223 rotates with the first door body 20 to exceed the second preset angle range, thereby preventing the first door body 20 from moving, thereby limiting the rotation angle of the first door body 20 to the second preset angle range.

Specifically, the fixing plate 231 of the present embodiment is configured with a circular arc-shaped side 233 at the outer circumference and a stop edge 234 continuous with the circular arc-shaped side 233. When the stop block 223 rotates along with the first door body 20 within the second predetermined angle range, the stop block 223 is located at the side of the circular arc-shaped side 233, and when the stop block 223 rotates to operate within the second predetermined angle range, the stop block 223 abuts against the stop edge 234.

Specifically, the second preset angle range of the present embodiment is designed according to actual situations, and may specifically be any value between 0 and 165 degrees.

No matter what the second predetermined angle range is, the stopping function of the second predetermined angle range to the first door body 20 and the stopping function of the rotation limiting member 222 to the second door body 30 are independent from each other and do not interfere with each other. That is, no matter what angle range the first door 20 rotates to, the second door 30 can still rotate in the first angle range relative to the first door 20, so as to reduce the mutual interference influence of the first door 20 and the second door 30, and improve the user experience. As a specific embodiment of the present invention, the present embodiment further provides a refrigerator 100, where the refrigerator 100 includes a refrigerator body 10, a first door 20, a second door 30, and a door assembly 200 on the upper surface. The refrigerator 100 using the door assembly 200 has a simple structure and low cost, and the rotation stoppers between the first door 20 and the second door 30 are independent from each other and do not interfere with each other.

Thus, it should be appreciated by those skilled in the art that while various exemplary embodiments of the invention have been shown and described in detail herein, many other variations or modifications which are consistent with the principles of this invention may be determined or derived directly from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
