The invention provides an electric pressure cooker and a rapid air exhaust control method. The electric pressure cooker comprises a cooker body, a cooker cover, an impeller, a motor, detection devicesand a controller, wherein the cooker cover is buckled to an inner pot and defines an airtight cooking cavity with the cooker body, and an air exhaust hole is arranged in the cooker cover; the impeller is mounted below the air exhaust hole; the motor is mounted on the cooker cover and connected with the impeller for driving the impeller to rotate; the detection devices are mounted on the cooker body and / or the cooker cover for detecting the working state parameters when the electric pressure cooker works; the controller is electrically connected with the detection devices and the motor. For the electric pressure cooker, when the air exhaust hole is opened for pressure relief, the impeller starts to rotate, so that sticky food can not overflow from the air exhaust hole, meanwhile, the detection devices are used for detecting the working state parameters of the electric pressure cooker related to the pressure in the cooker in real time, the pressure in the cooker is obtained according tothe detected working state parameters, in addition, the impeller is controlled to stop rotation when the pressure in the cooker is reduced to the safe range, so that a user can open the cooker coverfor taking out the food.
