Description

Clamshell Air Fryer with High Efficiency Drainage Steam Duct

technical field

The invention relates to the technical field of kitchen equipment, in particular to a flip-top type air fryer with a high-efficiency drainage steam duct.

Background technique

Air fryer is a new type of household appliance that uses high-speed, high-temperature air circulation technology to fry food. Compared with traditional electric fryers, the food made by it can reduce oil by 80%. It is easy to clean and safe in daily use. Economical and popular.

The existing air fryer generally includes a body, a cooking cavity is formed in the body, a hot air component that can send high-temperature air into the cooking cavity is arranged in the body, and a pot body for holding food is arranged in the cooking cavity. The high-temperature hot air generated by the hot air component heats the ingredients in the pot, and the hot air is fully in contact with the food, and the surface of the food is used to lose moisture instantly and quickly, or coupled with the oil produced by the food itself, the surface of the food forms a crispy taste, showing The effect of being fried.

Air fryers are mainly divided into two categories: pull-out air fryers and clamshell air fryers. Among them, for a flip-top air fryer, an air inlet and an air outlet are generally provided on the top of the upper cover.

For example, the utility model patent "A Flip-top Air Fryer with Even Heating", whose patent application number is CN201621044633.3 (announcement number is CN206603656U), discloses a flip-top type air fryer. The air inlet and outlet, the upper cover body is also provided with a accommodating cavity, the accommodating cavity is provided with an upper fan blade, and the upper fan blade introduces the cold air from the outside of the air fryer into the accommodating cavity through the air inlet, and removes the air through the air outlet. The heat in the accommodating cavity is discharged to dissipate heat to the upper cover.

However, for the above-mentioned flip-top air fryer, the hot air in the cooking cavity and the water vapor carried by it need to enter the inside of the upper cover first, and then be discharged into the outside atmosphere, which has a long path and is easy to escape to the components inside the upper cover. , it is inconvenient for the water vapor to be quickly discharged, which will cause the water vapor to condense into water droplets and drop on the food again, affecting the taste of the food, and the exhaust channel is not direct, the water vapor removal effect is slow, and the baking time of the food is increased.
