Smokeless air fryer

Abstract

The invention relates to a smokeless air fryer which finishes the cooking of foods and does not exhaust smoke by utilizing the high-speed hot air circulation technology. The smokeless air fryer comprises an air fryer fixed body and an air fryer movable body, wherein a top-driven power supply switch is arranged on one side of the lower end surface of a boss part at the front part of the air fryer fixed body, and a timer is arranged at the boss part; a top-driven boss is arranged on one side of the upper end surface of a handle of the air fryer movable body, and the handle is in locking and opening matching with an object containing mesh basket; the top-driven boss is in top-driven opening and closing matching with the top-driven power supply switch on one side of the lower end surface of the boss part of the air fryer fixed body; a planer screw type electric heating tube is arranged below hot air blades of the air fryer fixed body, a power supply joint of the planer screw type electric heating tube is connected with the inner wall of the air fryer fixed body through a connection assembly, and a tube body of the planer screw type electric heating tube is elastically connected with the inner wall of the air fryer fixed body through a tension spring; and the center of the bottom of an oil collecting backflow pot of the air fryer movable body is in an arc bulge shape, and the wall circumference and the bottom of the oil collecting backflow pot are in an arc shape.

Description

technical field [0001] The invention relates to a smokeless air fryer which utilizes high-speed hot air circulation technology to complete food cooking and discharge no oil fumes, and belongs to the field of air fryer manufacturing. Background technique [0002] CN201948771U, title "a new type of oil-free fryer", including: a loam cake, a metal outer pot lid in the loam cake, a shell, a metal outer pot set on the upper opening of the shell, and a metal outer pot built in the metal outer pot The grid-shaped food basket is characterized in that: a motor, a metal outer pot cover, a heating element and a fan are sequentially arranged in the upper cover, and the motor is arranged above the metal outer pot cover. The heating element and the fan are located under the metal outer pot cover, and the fan is installed on the output shaft extending downwards of the motor, and the heating element is located directly above the fan. After assembly, the metal outer pot cover is closed on th...

AI Technical Summary

Problems solved by technology

[0007] The deficiencies of the above-mentioned background technology: the one, there is no power cut-off device between the air fryer fixed body and the air fryer mobile body, after the air fryer mobile body is separated from the air fryer fixed body, its air fryer fixed body remains In the working state, not only the loss of energy consumption is large, but also the safety is poor; the second is that there is a reflective buckle between the electric heating plate and the fan in the fixed body of the air fryer, and the electric heating plate is located in the reflective buckle, so the fan generated The air flow cannot directly act on the electric heating plate, but only acts on the inner wall of the fixed pot of the air fryer through the surrounding of the buckle plate, and is pushed back from the inner wall of the pot to the food to be cooked, which not only reduces the thermal efficiency, but also causes the air fryer to The inner wall of the pot is overheated, and the temperature of the reflective plate and the electric heating plate is too high, which shortens the service life of the electric heating plate, resulting in overheating and burning

More importantly: when cooking meat, due to the high temperature of the electric heating plate and the reflective buckle plate, the fat dripping from the meat food is vaporized and instantly turns into The black oil fume is discharged outside the pot, which not only pollutes the environment, but also is not conducive to the health of the operator; the third is that because the electric heating plate and the fixed inner wall of the air fryer are non-elastic fixed connections, after the electric heating plate is energized, it will not work under high temperature conditions. The fixed connection between its electric heating plate and the fixed inner wall of the air fryer will not only easily cause damage to the inner wall of the pot, but also easily cause damage to the electric heating plate; the fourth is due to the annular shape of the air window on the upper end surface of the fixed body of the air fryer. The diversion discontinuous groove has two circles, resulting in insufficient negative pressure suction, which can neither form a dynamic air pressure balance in the air fryer, but also cause the hot air in the air fryer to be lost from the exhaust port of the air fryer, which not only causes heat loss, but also prolongs the life of the air fryer. The cooking time of the food affects the effect; fifth, the bottom of the oil-returning pot in the moving body of the air fryer is a raised fan-shaped structure, which causes the hot air flow in the air fryer to form a central heat whirlwind, and the heat The whirlwind not only destroys the dynamic balance of the airflow in the air fryer during the rising process, but also the concentrated rising hot airflow carries the grease to produce oily smoke at the moment of contact with the overheated electric heating plate and the overheated reflective buckle plate, and is caused by the air fryer. The smoke outlet is discharged outside the air fryer; Sixth, the transmission holes in the four directions of the "D"-shaped holes on the large fan blade and the small fan blade directly lead to the reduction of the plane strength of the fan blade, which is prone to micro-deformation of the fan blade plane, resulting in wind Unstable blade rotation, increased noise, and scratches with the casing
