AIR COOKING DEVICE
An air cooking device is equipped with a cooking cavity and includes a heating device located above the cooking cavity, a temperature measuring device, and a fan, wherein the fan is used to suck up the wind in the cooking cavity and blow it towards the heating device, and the hot air blows to the cooking cavity to cook food. The temperature measuring device is used to detect the temperature in the cooking cavity. The air cooking device also includes a shielding cover between the heating device and the temperature measuring device, where the shielding cover shields the heating device from radiating to and heating the temperature measuring device, so as to improve the accuracy of the temperature measurement of the temperature measuring device.
