Description

Air fryer

technical field

The utility model relates to a cooking vessel, in particular to an air fryer.

Background technique

With the improvement of people's quality of life, the requirements for air fryers in the market are getting higher and higher. The air fryer uses high-speed air circulation technology, and the unique combination of rapid circulation of hot air and internal spiral texture makes the cooking effect reach the effect and taste of fried food. That is, when heating, the high-temperature hot air is blown on the surface of the food in the pot to form a crispy surface layer, which quickly locks the moisture inside the food, so as to achieve the delicious and crispy taste of ordinary fried food.

The existing air fryer comprises a pot frame, a pot body and a cover. The pot frame is provided with a cavity for placing the pot body. The pot body is located in the cavity, and one end of the cover is connected to the pot frame. The tail is hinged, and the other end of the cover is openably connected with the front part of the pot support, and the fryer control device is installed at the front part of the pot support. A top-down hot air channel is opened on the cover, the top of the hot air channel communicates with the atmosphere, the bottom of the hot air channel communicates with the inner cavity of the pot body, a heating wire is installed inside the hot air channel, and an air pump is installed at the bottom of the hot air channel. When hot air is needed, the electric heating wire heats up the cold air brought in by the air pump, and after heating, it is introduced into the pot body, and the food stirring seat in the pot body turns the food over to make the food fully baked.

There are following defects in existing air fryers:

(1) Due to the need to heat the air in the ambient temperature to the required working temperature, the power consumption is large and the thermal efficiency is low;

(2) Since the air flow is blown to the same position inside the pot body from top to bottom, the food on the pot body near the air outlet is easily heated or even scorched, and the food on the pot body far away from the air outlet The food is not easy to be heated, and the heating is uneven, which affects the processing quality;

(3) Existing air fryers can only be used for grilling and have a single function. If you want to make pizza, cook, or stir-fry, you need to purchase an electric oven, electric rice cooker, and induction cooker, which are expensive and occupy a large space. .
