Fig. 12 is a first state diagram of the refrigerator door 100 according to an embodiment of the present invention; fig. 13 is a second state diagram of the refrigerator door 100 according to an embodiment of the present invention; fig. 14 is a schematic view of a third state of the refrigerator door 100 according to an embodiment of the present invention. The refrigerator door 100 may have three different states: the first state is that the door body 100 is closed; the second state is a state in which the vertical beam 120 rotates but the door body 100 is not opened; the third state is that the door body 100 has been opened.

Specifically, the first state is that the door body 100 is closed, the vertical beam 120 is in a sealed state of being unfolded to be matched with the door body 100 because the worm wheel 134 and the worm 133 have self-locking performance, a first limit structure 141 is arranged at the gear train for preventing the self-driving of the internal gear, and the deflector 136 is in an inactive state. The second state is a state where the vertical beam 120 is rotated but the door body 100 is not opened, and there may be the following two cases: the vertical beam 120 rotates to drive a photographing device on the vertical beam 120 to scan the internal state of the refrigerator; the door 100 is about to open, and the vertical beam 120 rotates by a predetermined angle to avoid interference with the opposite door or bottle seat, driving the connecting rod 132 to move to a pre-opened state. The third state is that the door body 100 is opened, at this time, the rotating shaft 137 is engaged with the connecting rod 132 but does not rotate, and the motor 131 only drives the driving lever 136 on the connecting rod 132 to act so as to realize door opening. Fig. 12 to 14 specifically show the relative relationship between the first gear 135 of the connecting rod 132 and the second gear 138 of the rotating shaft 137.

The present embodiment also provides a method for opening a refrigerator door, and fig. 15 is a schematic view of a method for opening a refrigerator door according to an embodiment of the present invention. The method for opening the refrigerator door is applicable to the refrigerator door 100 of any of the above embodiments. As shown in fig. 15, the method for opening the refrigerator door sequentially performs the following steps:

step S1502, acquiring an actual state of the vertical beam 120 of the door body 100;

step S1504, in the case that the vertical beam 120 rotates by a preset angle, determining whether to open the door body 100, if yes, executing step S1506;

in step S1506, the current state of the vertical beam 120 is maintained, and the lever 136 of the door body 100 continues to rotate to open the door body 100.

It should be noted that the refrigerator door 100 may have three different states. The first state is that the door body 100 is closed, the vertical beam 120 is in a sealed state of being unfolded and matched with the door body 100 because the worm wheel 134 and the worm 133 have self-locking performance, a first limit structure 141 is arranged at the gear train for preventing the self-driving of the internal gear, and the deflector 136 is in an inactive state. The second state is a state where the vertical beam 120 is rotated but the door body 100 is not opened, and there may be the following two cases: the vertical beam 120 rotates to drive a photographing device on the vertical beam 120 to scan the internal state of the refrigerator; the door 100 is about to open, and the vertical beam 120 rotates by a predetermined angle to avoid interference with the opposite door or bottle seat, driving the connecting rod 132 to move to a pre-opened state. The third state is that the door body 100 is opened, at this time, the rotating shaft 137 is engaged with the connecting rod 132 but does not rotate, and the motor 131 only drives the driving lever 136 on the connecting rod 132 to act so as to realize door opening.

Therefore, in step S1504, if the vertical beam 120 rotates by the preset angle, it is determined whether to open the door body 100, and if yes, the third state should be implemented, step S1506 is performed, the current state of the vertical beam 120 is maintained, and the lever 136 of the door body 100 continues to rotate to open the door body 100. When the determination result in step S1504 is no, the second state should be realized, and the following steps may be performed: the photographing device on the vertical beam 120 is started to photograph the stored picture inside the refrigerator.

According to the method for opening the refrigerator door body, by acquiring the actual state of the vertical beam 120 of the door body 100, judging whether to open the door body 100 under the condition that the vertical beam 120 rotates by a preset angle, and if yes, keeping the current state of the vertical beam 120, and continuously rotating the deflector 136 of the door body 100 to open the door body 100, automatic rotation of the vertical beam 120 can be realized, and the convenience of use of a user is improved; under the condition that the door body 100 is not opened, the photographing device on the vertical beam 120 is started to photograph and obtain the storage picture inside the refrigerator, so that a user can know the food storage condition conveniently.

In some alternative embodiments, the refrigerator door 100 may achieve a higher technical effect by further optimizing and configuring the above steps, and the following description is given in detail to the method for opening the refrigerator door according to this embodiment in conjunction with the description of an alternative execution flow of this embodiment, where this embodiment is merely illustrative of the execution flow, and when implemented, the execution sequence and the operation condition of some steps may be modified according to the specific implementation requirement. Fig. 16 is a detailed flowchart of a method of opening a refrigerator door according to an embodiment of the present invention. The method for opening the refrigerator door body comprises the following steps:

step S1602, obtaining the actual state of the vertical beam 120 of the door body 100;

step S1604, when the vertical beam 120 rotates by a predetermined angle, determining whether to open the door 100, if yes, executing step S1606, and if not, executing step S1608;

step S1606, the current state of the vertical beam 120 is maintained, and the lever 136 of the door body 100 continues to rotate to open the door body 100;

in step S1608, the photographing device on the vertical beam 120 is started to photograph and obtain the storage picture inside the refrigerator.

In the above steps, as mentioned above, the refrigerator door 100 may have three different states. The first state is a state in which the door body 100 is closed, the second state is a state in which the vertical beam 120 is rotated but the door body 100 is not opened, and the third state is a state in which the door body 100 has been opened. Therefore, in step S1604, if the vertical beam 120 rotates by a preset angle, it is determined whether to open the door body 100, and if yes, the third state should be implemented, step S1606 is performed, the current state of the vertical beam 120 is maintained, and the lever 136 of the door body 100 continues to rotate to open the door body 100. When the determination result in step S1604 is no, the second state should be implemented, and step S1608 may be executed: the photographing device on the vertical beam 120 is started to photograph the stored picture inside the refrigerator. It should be noted that, the photographing device on the vertical beam 120 may be a camera, and after photographing to obtain the storage picture, the photographing device may further perform image recognition on the storage picture to determine specific food storage information in the storage space.
