摘要： 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.

摘要： A control method for a drawer door of a refrigerator and the refrigerator. The refrigerator comprises a refrigerator body, a drawer door mounted in the refrigerator body in a front-back pushed and pulled mode, and a driving mechanism driving the drawer door to move forward and backward. The control method comprises: obtaining a door opening instruction or a door closing instruction; controlling the driving mechanism to drive the drawer door to move forward to open or move backward to close; detecting a resistance borne by the drawer door during the movement; determining whether the resistance is greater than a preset resistance threshold; and if yes, controlling the driving mechanism to stop running to enable the drawer door to stop moving.
