Problems solved by technology
[0004] In order to solve the above problems, the present invention proposes a control method for automatic opening and closing of the refrigerator door based on a photoelectric switch, through the induction of the diffuse reflection photoelectric switch and the way of controlling the DC electric push rod to open the refrigerator door, so as to solve the problem that the suction force of the refrigerator door is large and not good Opening and the problem that consumers’ hands are inconvenient to open the door when they are occupied

Embodiment Construction
[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0027] The freezer of the present invention needs to be equipped with three sensors on the front, and a DC push rod motor on the back, all of which are uniformly controlled by the internal control chip of the refrigerator. Among them, a sensor at the top uses a human sensor module, and when a person approaches (within 70 cm), it will output an induction signal to the control chip; the two sensors at the bottom use a diffuse reflection photoelectric switch, when an object approaches ( 10 cm) will output an induction signal to the control chip. The control rule is: after the human sensor module senses the existence of the human body, it outputs a high level to the control chip, and the two photoelectric switches act successively to realize the automatic door opening and closing operation.
[0028] Such as figure 1 As shown, the specific process ...

The invention discloses a refrigerator automatic door opening and closing control method based on a photoelectric switch, and belongs to the technical field of refrigerator door opening and closing. A top sensor, a left sensor and a right sensor are mounted on the front face of a refrigerator body, and a direct-current push rod motor is mounted on the back face and connected to a refrigerator door and a refrigerator body; a control chip is mounted in the refrigerator to uniformly control and complete automatic door opening and closing of the refrigerator; the top sensor is a human sensing module, and the left side sensor and the right side sensor adopt diffuse reflection type photoelectric switches; and after sensing the existence of a human body, the human sensing module outputs a high level to the control chip, and the two photoelectric switches act successively to realize automatic door opening and closing operation. The method is easy to operate, a user does not need to worry about the weight and suction problems of the door, and the refrigerator door can be opened and closed when the user holds objects with the two hands.
Description
technical field [0001] The invention belongs to the technical field of opening and closing doors of refrigerators, and in particular relates to a control method for automatically opening and closing doors of refrigerators based on a photoelectric switch. Background technique [0002] At present, in order to maintain a good seal and reduce cold leakage, the refrigerator has a greater suction force; and with the gradual improvement of the cooling effect, the temperature inside the cabinet is getting lower and lower, which will increase the negative pressure in the cabinet. The above two reasons make it difficult to open the refrigerator door. In order to solve this problem, some products on the market will add some auxiliary door opening devices on the freezer to reduce the resistance when lifting the cabinet door. [0003] Due to the large cabinet door or strong suction force, there are still unsatisfactory assistance in the way of auxiliary power door opening that exists on...
