Claims (4)

In the automatic door opening and closing method of the refrigerator, the first process of performing the function corresponding to the input key data when the key data is input by kissing can, and checks and compensates for the temperature, and the outside of the door after performing the first process A second process of setting the door open / close mode by analyzing the state data by inputting state data on the state, a third process of checking whether the door is open or not after performing the second process, and opening the door in the third process A fourth process of setting a door control timer upon request; and when the door is not driven by determining whether the door is to be driven after the fourth process is performed or when the door is not requested to be opened in the third process, the process returns to the first process. A fifth process of thinning, and a sixth process of opening the door or closing the door in the open state in the fifth process, and then returning to the first process, and the predetermined cycle of inter A seventh step of checking whether the door opening lag is set every time a gate is generated; and an eighth step of increasing the time of the door control timer when the door opening flag is set in the seventh step and checking whether the door control timer is a fixed time And a ninth step of setting the door driving timer at a predetermined time temporarily in the eighth step; and a door opening flag is not set in the seventh step, or the time of the door control timer is set in the eighth step. And a tenth step of driving the refrigerator control timer after performing the ninth step and returning to the program which was executed at the time of interrupt generation. The method of claim 1, wherein the second process inputs and stores state data on the external state and the door open state of the door, and then checks whether the door open request is requested. The method is characterized in that the order of return with the absence. According to claim 2, When the sixth process is determined to drive the door door opening or closing the door to check whether the door opening or closing, and then check the door opening timer, and abnormal state occurs during the door driving process And an abnormal state inspection process that checks the number of inspections and returns them to a normal date and time, and when an abnormal state occurs in the abnormal state inspection process, information is generated more and more strongly up to a predetermined inspection number. Characterized by consisting of a process. In the refrigerator, a keyboard 11 generating key data for the temperature control function and the door opening / closing function of the refrigerator and outputting the key data to the microcomputer 10, and cooling to perform the refrigerating and freezing functions under the control of the microcomputer 10. The driving circuit unit 12, the sensor unit 13 for detecting the open / closed state of the door and the external condition in front of the outer door to output the detection signals to the microcomputer 10, and the actuator 14 for opening and closing the door And an actuator driving unit (15) for driving the actuator (14) under the control of the microcomputer (10). ※ Note: The disclosure is based on the initial application.
