Abstract:
A control method for an automatic door opening and closing refrigerator. The refrigerator comprises a drawer door, a first door body, and a trigger switch for controlling opening or closing of the drawer door. The control method comprises the following steps: S1, acquiring a door opening instruction of the drawer door; S2, determining whether the first door body is in an open state; and S3, when the first door body is in the open state, after a trigger frequency N1 of the trigger switch within a preset time Ts reaches a preset trigger frequency Ns, controlling the drawer door to be opened. When the first door body is in the open state, whether a user has a door opening intention is determined by measuring the trigger frequency of the trigger switch within the preset time, thereby preventing the drawer door from being opened due to false triggering, and improving the safety performance when the drawer door is opened.
