Problems solved by technology

There are generally two methods of pressure relief. One method is to wait for the food in the pot to cool down and then open the lid when the pressure returns to atmospheric pressure. Up to 40-60min
Another method is to open the vent on the pot cover to discharge the steam to release the pressure. The depressurization time of this method only needs 2-3 minutes. Phenomenon

Abstract

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.

Description

technical field [0001] The invention relates to the field of cooking utensils, and more specifically, to an electric pressure cooker and a rapid exhaust control method for the electric pressure cooker. Background technique [0002] After the electric pressure cooker finishes cooking, the pressure inside the pot is still high, and the upper cover can only be opened to take out the food after the pressure is released. There are generally two methods of pressure relief. One method is to wait for the food in the pot to cool down and then open the lid when the pressure returns to atmospheric pressure. Up to 40-60min. Another method is to open the vent on the pot cover to discharge the steam to release the pressure. The depressurization time of this method only needs 2-3 minutes. Phenomenon. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] Therefore, an object of the present inve...
