Multifunctional air fryerTechnical Field
the invention belongs to the technical field of kitchen appliances, and particularly relates to a multifunctional air fryer.
Background
Along with the improvement of science and technology development and masses quality of life, people attach more importance to video health, the appearance of the air fryer solves the problem of food health brought to food cooking by using oil for traditional cooking equipment to a certain extent, the air fryer uses a high-speed air circulation technology to enable the cooking effect to reach the effect and the taste of fried food, namely, high-temperature hot air is generated in the fryer body to enable the surface of the food to form a crisp surface layer, the moisture in the food is locked, and the taste of common fried food is reached.
The existing air fryer cold air system generally adopts the peripheral air inlet of the top cover, a certain air inlet gap is reserved between the top cover and the periphery of the top of the shell, so that cold air can enter the air fryer and then flows into the cold air system through the flow guide holes in the upper cavity, and the cold air is discharged from the air outlet through the air outlet distributed at the bottom of the shell, thereby realizing the heat dissipation and the protection of the air fryer. The main defect of current scheme lies in, and the air inlet is little, and the intake is not enough, and the wind pressure is not enough, and it is few to drive the heat, and the heat dissipation is untimely, gathers hot unable diffusion easily, if after the area of increase air inlet, can produce certain noise, explodes the pot work when the air moreover and ends, and inside heat rises sharply and gathers at the top cap downside and be difficult for the diffusion, explodes the pot and causes harm to the air.
In addition, in the existing air fryer, the power cord is exposed outside the machine and can not be collected, and after the product is used up, the power cord can only be placed on a working table in a kitchen, so that the structure has the defects in two aspects: firstly, the appearance is affected; secondly, when a plurality of kitchen products were put on the workstation, there was the risk of inserting wrong plug, and the interface connection intensity of power cord is not good enough, inserts the power cord and can lead to the condition that the interface breaks away from because of receiving the pulling force, influences the use and experiences.
