Based on the above scheme, the refrigerator door and the refrigerator body are opened or closed by the door opening and closing device 10. When the clutch 4 is not electrified, a user can manually rotate the refrigerator door relative to the refrigerator body, the refrigerator door drives the hinge shaft 3 to rotate, at the moment, torque is only transmitted to the driven shaft 42 of the clutch 4, and the driving shaft 41 of the clutch 4 is not stressed, so that the refrigerator door can be opened and closed manually; when the clutch 4 is electrified, the driven shaft 42 of the clutch 4 is magnetically attracted to the driving shaft 41 under the action of magnetic force, so that the power generated by the driving assembly 2 is transmitted to the hinge shaft 3 through the driving shaft 41 and the driven shaft 42, thereby driving the hinge shaft 3 to rotate and further enabling the refrigerator door to be automatically opened and closed relative to the refrigerator body. Compared with the door opening and closing device 10 in the prior art, the door opening and closing device 10 of the refrigerator has the advantages of simple and compact structure, lower manufacturing cost, contribution to product popularization and application, and convenience in later maintenance.
In some embodiments, referring to fig. 1-4, the door opening and closing device 10 further includes an angle detection assembly 5 disposed in the housing 1, the angle detection assembly 5 includes a detection panel 51 and a plurality of detection elements 52, the plurality of detection elements 52 are integrated on the detection panel 51, the plurality of detection elements 52 are respectively disposed near the outer peripheral wall of the hinge shaft 3 and are sequentially spaced along the circumferential direction of the hinge shaft 3, and the outer peripheral wall of the hinge shaft 3 is provided with an adapter 35 that is matched with the detection elements 52 for sensing. Specifically, the control system of the refrigerator is electrically connected with the detection panel 51 to receive detection signals of the detection elements 52, when the driving assembly 2 drives the hinge shaft 3 to rotate through the clutch 4, the adapter 35 triggers the detection elements 52 at the opposite positions after rotating along with the hinge shaft 3 by a certain angle, so that the detection elements 52 generate detection signals and transmit the detection signals to the control system, thereby judging the opening angle of the refrigerator door relative to the refrigerator body, and the control system feedback controls the driving assembly 2 to further drive the hinge shaft 3 to achieve a fully closed door state or a fully opened door state, and meanwhile, the rotation positions of the hinge shaft 3 are controlled through interaction of the detection elements 52 and the adapter 35, so that the opening and closing positioning of the refrigerator door is achieved.
Further, the detecting element 52 of the embodiment of the present invention is a photoelectric sensor, and correspondingly, the adapting member 35 is a light reflecting member. When the hinge shaft 3 rotates, the adapter member 35 sequentially passes through the plurality of detection elements 52 and activates the corresponding detection elements 52, and the detection elements 52 generate detection signals and transmit the detection signals to the control unit, so that the control unit controls the driving assembly 2 to rotate the hinge shaft 3 through the detection signals of the detection elements 52, and further controls the unfolding position of the refrigerator door.
In some embodiments, referring to fig. 1 to 5, in order to ensure that the refrigerator door can be completely closed and completely opened when the hinge shaft 3 is at the limit 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 compression bar 61, a second compression bar 62, a first sensing element 63, and a second sensing element 64, and a middle portion of the first compression bar 61 is rotatably disposed in the housing 1; the middle part of the second compression bar 62 is rotatably arranged in the shell 1; wherein, the first groove 32 and the second groove 33 are arranged on the peripheral wall of the hinge shaft 3, and the hinge 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 state, the first end of the first pressing rod 61 is abutted to the outer peripheral wall of the hinge shaft 3, the second end of the first pressing rod 61 is in 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 outside the sensing range of the second sensing element 64; when the hinge shaft 3 is in the completely opened 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 is abutted to the outer 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.
Thus, when the first sensing element 63 transmits the generated sensing signal to the control system of the refrigerator, the refrigerator door is judged to be completely closed, and the refrigerator works normally to ensure that the cold quantity 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 refrigerator door is completely opened, and the unfolding angle of the refrigerator door is the largest, so that the user can store or carry food conveniently. When the hinge shaft 3 is located between the fully closed state and the fully open state, the first end of the first compression bar 61 and the first end of the second compression bar 62 are respectively abutted to the outer peripheral wall of the hinge shaft 3, and because the middle parts of the first compression bar 61 and the second compression bar 62 rotate with the housing 1, the second end of the first compression bar 61 and the second end of the second compression bar 62 are respectively located in the sensing ranges of the first sensing element 63 and the second sensing element 64, and 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 open state but not in the fully open state, and the refrigerator door can be further unfolded by the door opening and closing device 10 in the prior art after a long time.
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, and the second end of the first pressing rod 61 and the first sensing element 63 cooperate to sense, the second end of the second pressing rod 62 and the second sensing element 64 cooperate to sense, 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 refrigerator door, so as to precisely control the movement of the refrigerator door. In addition, the first sensing element 63 and the second sensing element 64 may be the same or different, which is not limited herein.
Specifically, in some embodiments, the first sensing element 63 and the second sensing element 64 are micro switches respectively; when the hinge shaft 3 is in a completely closed state, the second end of the first compression bar 61 is abutted to the sensing end of the first sensing element 63, and the second end of the second compression bar 62 is separated from the sensing end of the second sensing element 64; when the hinge shaft 3 is in the completely opened state, the second end of the first pressing lever 61 is separated from the sensing end of the first sensing element 63, and the second end of the second pressing lever 62 abuts against the sensing end of the second sensing element 64.
In the embodiment of the present invention, the first compression bar 61 and the second compression bar 62 are sequentially spaced apart along the axial direction of the hinge shaft 3, the position of the first groove 32 corresponds to the position of the first end of the first compression bar 61, and the position of the second groove 33 corresponds to the position of the first end of the second compression bar 62, so that the first end of the first compression bar 61 can be inserted into the first groove 32 but not into the second groove 33, and the first end of the second compression bar 62 can be inserted into the second groove 33 but not into the first groove 32.
In some embodiments, referring to fig. 6, the first end of the first compression bar 61 has a first protrusion 611 that mates with the first groove 32, and the first end of the second compression bar 62 has a second protrusion that mates with the second groove 33. When the hinge shaft 3 is in a fully closed 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, and the middle portion of the first pressing rod 61 and the middle portion of the second pressing rod 62 rotate around the housing 1, so that the second end of the first pressing rod 61 is located in 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 located in a position for sealing and closing the refrigerator body after receiving the sensing signal generated by the first sensing element 63. In the same principle, when the hinge shaft 3 is in the completely opened state, the second protruding portion abuts against the outer peripheral wall of the hinge shaft 3, the first protruding portion 611 is inserted into the first groove 32, and since the middle portion of the first compression rod 61 and the middle portion of the second compression rod 62 rotate around the housing 1, so that the second end of the second compression rod 62 is within the sensing range of the second sensing element 64, the second end of the first compression rod 61 is 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.
Further to be described is: the middle portion of the first pressing lever 61 and the middle portion of the second pressing lever 62 may be rotated with respect to the housing 1 by a rotation shaft, which is a conventional structure in the art, and a detailed description thereof will be omitted herein.
