Description

Refrigerator door control method and refrigerator Technical Field The invention relates to the technical field of refrigerators, in particular to a refrigerator door control method and a refrigerator. Background Currently, refrigerators have been widely used in home life. In the process of using the refrigerator, a user needs to manually open and close the door, and particularly when the door is closed, inconvenience is brought to the user because the two hands of the user are occupied by the articles. Disclosure of Invention The present invention has been made in view of the above problems, and has as its object to provide a control method of a refrigerator door and a refrigerator which overcome or at least partially solve the above problems. An object of the present invention is to realize automatic opening and closing of a refrigerator door. Another object of the present invention is to improve the accuracy of judging whether or not door opening is required. It is a further object of the present invention to improve the accuracy of determining whether a door is required to be closed. In particular, according to an aspect of the present invention, there is provided a control method of a refrigerator door, comprising: Acquiring the open and closed states of a refrigerator door; starting a human sense detection function corresponding to the open/close state; Human body states in a preset range of the refrigerator are detected through a human sense detection function, and the opening and closing of the refrigerator door are controlled according to the human body states. Optionally, when the open/close state is the closed state, detecting a human body state within a preset range of the refrigerator by a human sense detection function, and controlling the opening/closing of the refrigerator door according to the human body state includes: Acquiring the real-time moving speed of a human body; judging whether the real-time moving speed is in a decreasing state or not; If yes, the refrigerator door is opened.
