A cooking method using the pressure air fryer 10, firstly, the middle cover 123 seals the through hole 1221 on the lower cover 122, and pressure cooks the ingredients in the pot body assembly 11; then exhaust through the exhaust valve 13; The middle cover 123 is lowered to open the through hole 1221 , and the hot air heating assembly 14 heats the ingredients in the pot body assembly 11 .

When used as pressure and air frying at the same time, the specific work is as follows: put the shelf 114 in the inner pot 111, add a certain amount of water, place the ingredients to be processed on the shelf 114, close the lid assembly 12 to start, and the lid The middle cover 123 on the assembly 12 is in a closed state, the heating plate under the inner pot 111 is working, and the internal water continuously cooks the ingredients until the set time. During this period, when the pressure reaches the set value, the exhaust valve 13 is opened to exhaust air, and the inner pot 111 is maintained. A certain pressure value is then exhausted. After exhausting, the middle cover 123 is lowered to open the through hole 1221. The fan 142 in the lid assembly 12 is driven by the motor 141 to rotate, and the heat generated by the heating pipe 143 is carried into the inner tank 111 by the circulating air. The ingredients are heated inside, and the ingredients are quickly cooked by first high-pressure cooking. Because they are processed in a high-humidity state, the loss of moisture in the ingredients is avoided, and then baked through hot air circulation, the ingredients can be crispy outside and tender inside.

To sum up, with the lifting and lowering of the middle cover 123, the pressure air fryer can automatically and conveniently switch between pressure and normal pressure. For large or difficult-to-cook ingredients, the ingredients can be pressure-cooked first. After being cooked, the air is then exhausted, the middle cover 123 is opened, and the hot air heating element 14 starts to circulate and heat the ingredients. In this way, by first high-pressure steaming the ingredients, the ingredients are rapidly cooked inside and out. Since the ingredients are processed in a high-humidity state, the loss of water vapor in the ingredients is avoided. , and then baked by hot air circulation, so that the ingredients can achieve the effect of crispy outside and tender inside, better taste, and can effectively shorten the air frying time, and the energy consumption is also small. In addition, it can also be used as a separate function, for example, the function of a pressure cooker and an air fryer can be realized independently.
