The first end of the hinge shaft is rotatably arranged in the shell in a penetrating way, and the second end of the hinge shaft is fixedly connected with the refrigerator door;
the angle detection assembly is arranged in the shell and comprises an induction panel and a plurality of induction elements integrated on the induction panel, the induction elements are respectively close to the peripheral wall of the hinge shaft and are sequentially spaced along the circumferential direction of the hinge shaft, and the peripheral wall of the hinge shaft is provided with an adapter matched with the induction elements for induction;
The driving assembly is arranged in the shell and is in transmission connection with the hinge shaft to drive the hinge shaft to rotate between a fully closed door state and a fully opened door state; and
The control unit is electrically connected with the driving assembly and the induction panel, and the control unit controls the refrigerator door to open and close on the refrigerator body by adopting the refrigerator door opening and closing angle control method according to any one of claims 1-3.
5. The refrigerator as claimed in claim 4, wherein the adapter includes a sleeve portion sleeved on the outer circumference of the hinge shaft and a light reflecting portion protruding from the sleeve portion, and the light reflecting portion is coupled to the sensing element to sense.
6. The refrigerator as claimed in claim 4, wherein the hinge shaft has at least one coupling groove or coupling protrusion formed at an outer circumferential wall of the second end thereof, and the refrigerator door is provided with a bushing interference-fitted with the second end of the hinge shaft.
7. The refrigerator of claim 4, wherein a through hole through which the first end of the hinge shaft passes is formed at the bottom of the housing, a bearing groove is formed on the inner wall of the housing along the outer circumference of the through hole, a bearing is pre-buried in the bearing groove, and the first end of the hinge shaft passes through the inner ring of the bearing so that the first end of the hinge shaft can rotatably pass through the housing.
