A multifunction safe electric pressure cooker includes a lid, an outer body, a warming container, a control panel, an inner tank, a sealant washer, a heating plate under the inner tank, and a control device. The control device comprises a control circuit, a pressure switch, and a temperature control device. The lid has a floating valve, a pressure discharging valve, and a safety valve. Between the heating plate and the warming container there is a spring device. Under the heating plate is a pole. The control device employs a sensor to determine whether the inner tank is placed in the cooker. Between the lid and the body sets a lid safety control switch that connected to the control circuit. The electric pressure cooker is more convenient and durable, can fry and sauté food, and includes multiple safety devices.
