In some embodiments, referring to fig. 1 to 5, in order to ensure that the door of the refrigerator can be completely closed and completely opened when the hinge shaft 3 is at the extreme position, the door opening and closing device 10 further includes a door opening and closing sensing assembly 6 disposed in the housing 1, the door opening and closing sensing assembly 6 includes a first pressing rod 61, a second pressing rod 62, a first sensing element 63 and a second sensing element 64, and a middle portion of the first pressing rod 61 is rotatably disposed in the housing 1; the middle part of the second pressure lever 62 is rotatably arranged in the shell 1; wherein, the peripheral wall of the articulated shaft 3 is provided with a first groove 32 and a second groove 33, and the articulated shaft 3 can rotate between a completely closed door state and a completely opened door state; when the hinge shaft 3 is in a completely closed door state, the first end of the first pressing rod 61 abuts against the peripheral wall of the hinge shaft 3, the second end of the first pressing rod 61 is located within the sensing range of the first sensing element 63, the first end of the second pressing rod 62 is inserted into the second groove 33, and the second end of the second pressing rod 62 is located outside the sensing range of the second sensing element 64; when the hinge shaft 3 is in a fully open state, the first end of the first pressing rod 61 is inserted into the first groove 32, the second end of the first pressing rod 61 is outside the sensing range of the first sensing element 63, the first end of the second pressing rod 62 abuts against the peripheral wall of the hinge shaft 3, and the second end of the second pressing rod 62 is within the sensing range of the second sensing element 64.
Therefore, when the first sensing element 63 transmits the generated sensing signal to the control system of the refrigerator, the door of the refrigerator is judged to be completely closed, and the refrigerator works normally to ensure that the cold energy is not leaked; when the second sensing element 64 transmits the generated sensing signal to the control system of the refrigerator, it is determined that the door of the refrigerator is fully opened, and the door of the refrigerator is unfolded at the maximum angle, so that the user can store or carry food conveniently. When the hinge shaft 3 is located between the completely closed door state and the completely opened door state, the first end of the first pressing rod 61 and the first end of the second pressing rod 62 are respectively abutted to the peripheral wall of the hinge shaft 3, and since the middle parts of the first pressing rod 61 and the second pressing rod 62 and the shell 1 rotate mutually, the second end of the first pressing rod 61 and the second end of the second pressing rod 62 are respectively located in the sensing range of the first sensing element 63 and the second sensing element 64, at this time, the first sensing element 63 and the second sensing element 64 respectively transmit the generated sensing signals to the control system of the refrigerator, so as to judge that the refrigerator door is in the opened state but not in the completely opened door state, and after a long time, the alarm can be given or the refrigerator door can be further unfolded by the door opening and closing device 10 in the prior art.
It should be further noted that the present invention is not limited to the specific structure or shape of the first sensing element 63 and the second sensing element 64, for example, the first sensing element 63 and the second sensing element 64 may be a micro switch, a proximity sensor, a hall sensor, or the like, respectively, and the control system of the refrigerator obtains the signals of the first sensing element 63 and the second sensing element 64 to determine the position of the door of the refrigerator by the second end of the first pressing rod 61 and the first sensing element 63 cooperating to sense, and the second end of the second pressing rod 62 cooperating to sense, so as to precisely control the movement of the door of the refrigerator.

When the hinge shaft 3 is in a completely closed door state, the first protruding portion 611 abuts against the outer peripheral wall of the hinge shaft 3, the second protruding portion is inserted into the second groove 33, because the middle portion of the first pressing rod 61 and the middle portion of the second pressing rod 62 rotate around the housing 1, the second end of the first pressing rod 61 is located within the sensing range of the first sensing element 63, the second end of the second pressing rod 62 is located outside the sensing range of the second sensing element 64, and the control system of the refrigerator determines that the refrigerator door is in a position for hermetically closing the refrigerator body after receiving a sensing signal generated by the first sensing element 63. On the same principle, when the hinge shaft 3 is in the fully open state, the second protrusion abuts against the outer peripheral wall of the hinge shaft 3, the first protrusion 611 is inserted into the first groove 32, and since the middle of the first pressing rod 61 and the middle of the second pressing rod 62 rotate around the housing 1, the second end of the second pressing rod 62 is located within the sensing range of the second sensing element 64, the second end of the first pressing rod 61 is located outside the sensing range of the first sensing element 63, and the control system of the refrigerator determines that the opening angle of the refrigerator door is the largest after receiving the sensing signal generated by the second sensing element 64.
