Description

New structure cooker with air-frying function

Technical Field

The invention relates to the technical field of food cooking pots, in particular to a pot with a novel structure and an air-frying function.

Background

The traditional air fryer and the electric pressure cooker are common food cooking cookers, the common air fryer only has the function of cooking food by hot air, and the common pressure cooker only has the function of pressure cooking. However, a multifunctional pot having both functions of cooking food with hot air and pressure cooking appeared later, and as the invention patent of the pot cover having air heating and high pressure sealing functions and the pot having the pot cover in the prior art with patent number CN201910705670.6, the invention discloses a pot cover having air frying and pressure frying pot and a pot having the pot cover using the same, the pot has both functions of air frying pot and air heating component installed in the rotary pot cover installation cavity, and has a pressure pot cover detachably installed at the front end of the air installation cavity. When the air fryer function is used, the pressure cooker cover is not installed; when the pressure cooker is used, the pressure cooker cover with the pressure relief valve is installed. However, no matter the traditional air fryer or the novel multifunctional pot with the functions of cooking food by hot air and pressure cooking is adopted, when the air fryer is used, the hot air generated by the air heating assembly and used for cooking food is guided by the inner surface of the reflecting cover arranged in the pot cover above the fan blades and the heater, so that the hot air enters the inner pot containing cavity used for containing food in the pot body. But the design size of the reflecting cover opening is different, so that the butt joint gap between the reflecting cover opening and the inner pot opening is large or staggered; for the multi-functional pot appearing later, the detachable pressure pot cover can make the reflector opening and the inner pot opening generate larger gap when not being installed, so that the hot air which is originally blown to the inner pot accommodating cavity can be lost from the gap before being blown to the inner pot accommodating cavity, the food processing time is long, and the energy is wasted.
