The invention provides an electric oven, which includes a box body, a cooking cavity, a heating device and a controller. A disc is arranged in the cooking cavity, and several pressure detection devices are evenly distributed on the peripheral edge of the disc. The pressure detection devices include springs and A pressure sensor, one end of the spring is connected with the circumferential edge of the disc, and the other end is connected with the pressure sensor, and the pressure sensor is arranged on the bottom surface of the cooking cavity; it also includes a voice prompt unit, and the controller receives and calculates the pressure sensor in several pressure detection devices. The pressure difference between the feedback pressure signals, when one of the pressure differences is greater than the preset threshold, the controller controls the voice prompt unit to make a sound, prompting the user to adjust the position of the food on the disc; the present invention uses the controller and the voice prompt The unit prompts the user to adjust the position of the food on the disc, which can better bake the food and prevent the food from being unevenly baked, shaking or even falling out of the disc during the baking process.
