The outstanding disadvantage of this sealing method is: whether the door body is locked and to what extent, people cannot know, but subjectively feel that the refrigerator door has been locked
This situation increases the risk of air leakage and cold leakage of the door body, which seriously affects the functions that can be realized by the special area.

specific Embodiment 1
[0025] see figure 1 As shown, this embodiment provides a refrigerator door closure detection method, including the following steps:
[0026] A00: When the controller detects that the door switch is closed, the control distance sensor detects the actual distance L between the refrigerator door and the refrigerator box;
[0027] A01: The controller judges whether the actual distance L is less than or equal to the preset distance L0; if so, execute A08; if not, execute A03;
[0028] A03: The controller judges whether the detection time T is less than the preset time T0; if yes, execute A04; if not, execute A05;
[0029] A04: The controller controls the actuator to close the door and execute A00;
[0030] A05: The controller controls the infrared sensor to detect whether there are obstacles in the refrigerator box and the refrigerator door; if yes, execute A06; if not, execute A07;
[0031] A06: The controller judges whether the obstacle is removed within the interval time T1. ...

[0035] This embodiment provides a method for detecting closure of a refrigerator door, including the following steps: A00: when the controller detects that the door switch is closed, control the distance sensor to detect the actual distance L between the refrigerator door and the refrigerator box;
[0036] A01: The controller judges whether the actual distance L is less than or equal to the preset distance L0; if so, execute A08; if not, execute A03;
[0037] A03: The controller judges whether the detection time T is less than the preset time T0; if yes, execute A04; if not, execute A05;
[0038] A04: The controller controls the actuator to close the door and execute A00;
[0039] A05: The controller controls the infrared sensor to detect whether there are obstacles in the refrigerator box and the refrigerator door; if yes, execute A06; if not, execute A07;
[0040] A06: The controller judges whether the obstacle is removed within the interval time T1. Here, the specific meth...

Abstract
The invention discloses a refrigerator door body closing detection method and relates to the technical field of refrigerator door body closing detection. The refrigerator door body closing detection method comprises the following steps: controlling a distance sensor to detect an actual spacing L between a refrigerator door body and a refrigerator box body when a controller detects that a door switch is closed; judging whether the actual spacing L is smaller than or equal to a preset spacing L0 through the controller; and controlling an infrared sensor to detect whether an obstacle exists between the refrigerator box body and the refrigerator door body or not through the controller. The refrigerator door body closing detection method is capable of controlling and detecting the actual spacing L between the refrigerator door body and the refrigerator box body and judging whether the actual spacing L is smaller than or equal to the preset spacing L0 through the controller so as to control the infrared sensor to detect whether the obstacle exists between the refrigerator box body and the refrigerator door body or not in a preset time T0; and the refrigerator door body closing detection method is also capable of rapidly, accurately and objectively judging whether the refrigerator door body is locked or not and thoroughly avoiding the problems of air leakage and cold leakage caused when the door is not locked so as to ensure stability and reliability of functions of special areas.
Description
technical field [0001] The invention belongs to the technical field of refrigerator door closing detection, and in particular relates to a refrigerator door closing detection method. Background technique [0002] With the development of technology and the progress of society, there are more and more special areas in the refrigerator, and the functions are getting stronger and stronger, such as vacuum preservation area, oxygencontrol area, high humidity area, etc., all of these areas must be sealed. . At present, the sealing of the door body in the special area is mostly realized by sealing materials and locking structures. The outstanding disadvantage of this sealing method is: whether the door body is locked, and to what extent, people cannot know, but subjectively feel that the refrigerator door has been locked. This situation increases the risk of air leakage and cold leakage of the door body, which in turn seriously affects the functions that can be realized by the sp...
