Embodiment 1

[0020] Embodiment 1: A refrigerator door opening and closing control method based on angle and angular velocity.

[0021] A refrigerator door opening and closing control method based on angle and angular velocity, the specific steps are as follows:

[0022] When the refrigerator door 2 is in a closed state, the controller enters a sleep mode to reduce power consumption. When the controller detects that the values ​​returned by the angular velocity sensor and the angle sensor change, it wakes up the controller and starts working. Note that the data returned by the angle sensor when the refrigerator door 2 starts to move is θ 0 , the data returned by the angular velocity sensor is ω 0 , the real-time angle of refrigerator door 2 is θ r , the real-time angular velocity of refrigerator door 2 is ω r , in order to distinguish whether the current state of the refrigerator door 2 is opening or closing, record the time when the refrigerator door 2 is opened ω r >0, ω when refrig...

Embodiment 2

[0027] Embodiment 2: a kind of refrigerator.

[0028] A refrigerator, comprising a box body 1, a refrigerator door 2, a rotating shaft 3, a gear 4 and a motor 5, the gear 4 is installed on the rotating shaft 3, the rotating shaft 3 is connected to the motor 5 through the meshing of the gear 4, because the motor 5 It is only responsible for power-assisted driving. By inputting a certain current, the motor generates a small torque to generate power for the closing of the refrigerator. Therefore, its power needs to be selected to be relatively small, and the motor 5 cannot be self-locking. There are also several connections on the shaft 3 part 6, the box body 1 and the refrigerator door 2 are connected through the connecting part 6 on the rotating shaft 3, an angle sensor and an angular velocity sensor are also arranged on the refrigerator door 2, and a controller is arranged inside the refrigerator door 2 for Detect the opening angle and angular acceleration of the refrigerator ...

Embodiment 3

[0029] Embodiment 3: a computer-readable storage medium.

[0030] A computer-readable storage medium is used to store a computer program, and when the computer program is invoked by a processor, the method for controlling the opening and closing of the refrigerator door based on the angle and angular velocity described in Embodiment 1 is implemented.

Abstract

The invention provides a refrigerator door opening and closing control method based on angle and angular velocity, computer readable storage media and a refrigerator. The method comprises the steps that angle and angular velocity data of a refrigerator door are detected in real time, the opening and closing state of the refrigerator door is judged by analyzing the angle and the angular velocity, amotor is controlled to operate according to the opening and closing state of the refrigerator door, and therefore the speed of the refrigerator door is controlled. According to the refrigerator dooropening and closing control method based on the angle and the angular velocity, the computer readable storage media and the refrigerator, the angle and the angular velocity are judged, and the motor is intervened in the closing process of the refrigerator door, so that the secondary spring opening of the refrigerator door and the toppling of objects in the refrigerator caused by excessive force are avoided, and the refrigerator door are ensured to be stably closed.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a method for controlling the opening and closing of refrigerator doors based on angle and angular velocity, a computer-readable storage medium and a refrigerator. Background technique [0002] Nowadays, with the continuous improvement of living standards, refrigerators have become indispensable household appliances for people's lives. After the user has finished picking up the items in the refrigerator, if the force is too high during the process of closing the refrigerator door, the refrigerator door will pop open again, resulting in waste of resources, and even worse, the items in the refrigerator may be dumped, resulting in indoor pollution of the refrigerator. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a refrigerator door opening and closing control method based on angle and angular velocity, which us...
