technical field

The invention relates to the technical field of air fryers, in particular to an air fryer with a sealed cavity of a rotary pot body.

Background technique

An air fryer is a smart appliance that uses high-speed circulating high-temperature airflow instead of the hot oil in the original frying pan to fry food. The body of the existing air fryer generally includes a closed frying and roasting cavity, a pot body for holding food, a heating element and a fan that can send high-temperature and high-speed air into the inside of the pot body, and the hot air is generated by the heating element, and then used. The fan blows hot air into the pot to heat the food, so that the hot air circulates in the pot, and the food itself is used to fry food. fried effect.

The existing air fryer relies on the circulation of hot air to heat the food in the pot. The hot air goes down from the mouth of the pot to the bottom of the pot, from the wall to the center of the pot, and the temperature gradually decreases from the corner of the pot to the center of the pot. The food is in a relatively static state, which causes the internal heat distribution to be uneven, and the food at the corners of the pot will receive more heat; the airtight frying cavity needs to have holes to discharge oil fumes, but the opening of the holes It destroys the airtightness and reduces the efficiency of heat utilization. The small hole results in the formation of high pressure in the frying cavity. At the same time, the bottom of the pot is completely sealed, and the negative pressure at the bottom will prevent the downward circulation of air, and the hot air cannot fully contact with the food. The oil and moisture on the surface of the food cannot be fully taken away, which affects the working efficiency of the air fryer and reduces the frying effect.
