a06: the controller judges whether the barrier is removed within the interval time T1; if yes, A04 is executed; if not, executing A07;
a07: the controller controls the alarm to alarm;
a08: and the system detection is finished.
As a preferred technical solution, the manner for the controller to determine whether the obstacle is removed within the interval time T1 in a06 is as follows: the controller controls the infrared sensor to detect whether the refrigerator body and the refrigerator door body have obstacles.
As a preferred technical solution, the range of the preset distance L0 is as follows: 1.5-3 mm.
As a preferred technical solution, the range of the preset time T0 is as follows: 3-5 min.
As a preferred technical solution, the range of the interval time T1 is: 1.5-3 min.
The invention has the following beneficial effects:
the controller controls and detects the actual distance L between the refrigerator door body and the refrigerator body and judges whether the actual distance L is smaller than or equal to the preset distance L0 or not, and then whether an obstacle exists between the refrigerator body and the refrigerator door body or not is detected through the infrared sensor at the preset time T0 or not is controlled; whether the refrigerator door body is locked or not is judged quickly, accurately and objectively, the problems of air leakage and cold leakage caused by the fact that the door is not locked are thoroughly solved, and therefore the stability and the reliability of the special area function are guaranteed.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
