Publication number: 20220275675Abstract: A refrigerator, comprising an automatic door-opening/closing apparatus mounted on a refrigerator body for driving the opening and closing of a door. When opening the door, if a first obstacle detecting apparatus detects the presence of an obstacle in front of the door, then the automatic door opening/closing apparatus stops the opening of the door; when closing the door, if a second obstacle detection apparatus detects the presence of an obstacle behind the door, then the automatic door-opening/closing apparatus stops the closing of the door. This stops the movement of the door upon the discovery of an obstacle while opening or closing the door, thus preventing the door from being damaged by collision, and when the obstacle is a person, preventing physical injuries from being caused.Type: ApplicationFiled: March 18, 2020Publication date: September 1, 2022Applicants: QINGDAO HAIER REFRIGERATOR CO., LTD., HAIER SMART HOME CO., LTD.Inventors: Bin HUI, Ning WANG, Shidong LI, Zhijun LIU, Xiaobin HU
