Air fryer with efficient cold air circulation function

Abstract

The invention provides an air fryer with an efficient cold air circulation function. The air fryer comprises a shell; the shell comprises an upper shell body and a lower shell body; an upper air inlet is formed in the upper shell body; a lower air inlet is formed in the lower shell body; an inner container is arranged in the lower shell; a wind scooper is arranged in the upper shell body; a window for blowing out cold air and hot air is formed in the wind scooper; a lower cold air interlayer is formed between the lower shell body and the inner container; an upper cold air interlayer is formed between the upper shell body and the wind scooper; a heat insulation cover is arranged in the wind scooper; the wind scooper is divided into an upper cold air cavity and a lower hot air cavity by the heat insulation cover; an air duct wall is annularly arranged on the upper end surface of the wind scooper and is provided with a cold air outlet aligned with the window; the upper end face of the wind scooper is further provided with a plurality of wind guide ribs which are arranged at intervals and surrounded by the air duct wall; the wind guide ribs are arranged around a cooling fan in the vertical projection direction, and cold air in the cold air cavities flows to the cold air outlet under the guidance of the wind guide ribs. Loss and loss of the cold air can be reduced, and the cold air can be discharged more smoothly.

Description

technical field [0001] The invention relates to an air fryer. Background technique [0002] The general structure of the air fryer is as follows: including the shell, the shell includes the upper shell and the lower shell, the lower shell is equipped with an inner tank, the upper shell is equipped with a wind guide cover, and the wind guide cover is provided with windows for blowing out cold air and hot air. , the upper shell is provided with an air outlet corresponding to the window, a lower cold air interlayer is formed between the lower shell and the inner tank, an upper cold air interlayer is formed between the upper shell and the wind guide cover, and the upper cold air interlayer and the lower cold air interlayer are mutually Unicom. A heat shield is arranged inside the wind guide cover, and the heat shield separates the wind guide cover into an upper cold air chamber and a lower hot air chamber, and an electric heating device is arranged in the hot air chamber. A dr...

Problems solved by technology

It also has the disadvantage that the guide wall is installed in the wind guide cover, which actually only reduces the volume of the cold air chamber, and the cold wind still forms turbulent flow in the guide chamber, and even the turbulent flow is more intense due to the reduced volume of the cold air chamber. , the cold air cannot be exported smoothly
