The hot air heating assembly 14 comprises a motor 141, a fan 142 and a heating pipe 143 which are sequentially arranged from top to bottom, the fan 142 is installed on an output shaft of the motor 141, and the motor 141 drives the fan 142 to rotate, so that hot air is blown to the inner container 111 to circularly heat food materials, the structural layout is compact, heat exchange is sufficient, and good heat circulation heating is easily formed on the food materials of the inner container 111.

Referring to fig. 5, when the pressure cooker is used as a single pressure cooker, the cooker cover assembly 12 is opened, the shelf 114 of the inner container 111 is taken out, food materials, water and the like are put in, the cooker cover assembly 12 is closed and then started, the middle cover 123 is kept in a sealing state with the lower cover 122, a closed space is formed between the inner container 111 and the cooker cover assembly 12, the inner container 111 is heated by the heating plate, the air pressure rises, and the steam exhaust valve is operated to exhaust steam when the pressure rises to a set value, so that a certain pressure value can be maintained in the inner container. Compare ordinary electric pressure cooker, increased in addition after the lid 123 structure, can reduce the temperature of inner bag 111 more fast, behind exhaust valve 13 exhaust, inner bag 111 pressure drops to the ordinary pressure condition after, opens lid 123 in, and motor 141 drives fan 142 and rotates the air flow who accelerates inner bag 111, more does benefit to the heat dissipation cooling.

Referring to fig. 6, when the air fryer is used as an independent air fryer, the shelf 114 is placed in the inner container 111, food to be processed is placed on the shelf 114, the cooker cover assembly 12 is closed and started, the middle cover 123 on the cooker cover assembly 12 is opened, the fan 142 is driven by the motor 141 to rotate, and heat generated by the heating pipe 143 is brought into the inner container 111 by the circulating air to heat the food.

In a cooking method using the pressure air fryer 10, firstly, the middle cover 123 seals the through hole 1221 of the lower cover 122, and the food is pressure-cooked in the pot body assembly 11; then exhausted through the exhaust valve 13; the middle cover 123 descends to open the through hole 1221, and the hot air heating assembly 14 heats the food material in the pot body assembly 11.

When the pressure and air frying device is used simultaneously, the concrete work is as follows: put into shelf 114 in the inner bag 111, and add certain water yield, place the edible material that will process on the shelf 114, close a kind of deep pot lid subassembly 12 and start, well lid 123 on the deep pot lid subassembly 12 is in the closed condition, the heating plate below the inner bag 111 works, inside water is continuously cooked and is eaten the material to the setting time, when the pressure reaches the setting value during, exhaust valve 13 opens the exhaust, maintain certain pressure value in the inner bag 111, then the exhaust, well lid 123 descends after the exhaust and opens through-hole 1221, fan 142 in the deep pot lid subassembly 12 rotates under the motor 141 drive, the heat that heating pipe 143 produced is brought into inner bag 111 by the circulated air and heats the edible material, eat material quick curing through cooking high pressure earlier, owing to be in processing under the high humid state, avoid the loss of aqueous vapor in the edible material, again through heated air circulation toasts, eat material can reach the effect of crisp interior tender outside.

In conclusion, with the lifting of the middle cover 123, the pressure and normal pressure switching of the pressure air fryer can be automatically and conveniently realized, the food material can be subjected to pressure cooking firstly for large or difficult-to-cook food materials, the food materials are cooked to a certain degree and then exhausted, the middle cover 123 is opened, and the hot air heating assembly 14 starts to circularly heat the food materials. In addition, the pressure cooker can be respectively used as a single function, for example, the function of the pressure cooker can be realized independently, and the function of the air fryer can also be realized independently.
