Abstract
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.
