Principle of operation

The working principle of the air fryer to which the present application relates is briefly explained below.

In the working state, the air fryer is divided into a cold air generating and discharging process and a hot air generating and discharging process. It should be appreciated that these two processes occur substantially simultaneously. For clarity, the two are described separately.

Cold air generating and discharging process

Air is drawn into the interior of the air fryer housing from an air intake opening in the housing of the air fryer. The air suction opening can be arranged at any position of the air fryer, such as right above, obliquely above, laterally and rearwards, as long as the air suction opening can ensure the communication between the shell and the outside air.

A cold air cavity is formed between the upper surface of the upper cover plate 4 of the volute casing and the motor cover 1. The heat dissipation fan blade 10 is arranged in the cold air cavity. The cold air cavity is directly communicated with a cold air outlet on the motor cover 1 and then communicated with a cold air outlet 2a of the exhaust cover. Under the action of the motor 2, negative pressure is formed around the heat dissipation fan blades 10, outside cold air is sucked into the shell and sucked into the motor cover, and the cold air and the shell are subjected to heat exchange fully, so that the temperature rise of the shell is effectively reduced. The heat dissipation fan blade 10 discharges redundant cold air to the outside of the cavity body, so that the temperature inside the machine is ensured to be excessively high, a user is prevented from being scalded, and the temperature of the machine is ensured to be normal during working.

Hot air generation and discharge process

The arrows in fig. 1 show the hot air flow path of the zoned air slinger to which the present application relates.

A scroll-like, preferably eccentric scroll-like, is formed between the scroll upper cover plate 4 and the scroll lower cover plate 6. The turbine fan blade 5 is arranged in a volute curve hot air channel formed by the volute upper cover plate 4 and the volute lower cover plate 6.

When the electric fan works, the turbine fan blade 5 is driven by the motor 2 to rotate. The air is thrown out to the impeller all around under the effect of centrifugal force, and is blown out towards the volute air outlet 6c through the volute for the air is discharged by the pressure boost. After the air in the impeller is discharged, the pressure in the impeller is lower than that of the air inlet, and new air is sucked in from the central hole 6b of the lower volute cover plate in the middle of the lower volute cover plate 6 below the turbine fan blade 5 under the action of pressure difference. And this new air passes through the heat-generating tube 7 before being sucked in and thus has been heated.

The turbine fan blade 5 blows hot air to the lower shell of the fryer, namely the fryer barrel assembly, through the volute air outlet 6c of the volute lower cover plate 6 after the heated air is pressurized. The hot air reaches the bottom of basket 8 vertically along front air guide grooves 8a outside basket 8 and comes into contact with the bottom of frying tub 9. Those skilled in the art will appreciate that the turbine blades 5, acting as turbine blades, can provide sufficient power to blow hot air downwardly to the bottom of the fry vat, or very close to the bottom of the fry vat.

The hot air reaching the bottom of the frying tub 9 is diffused upward at the bottom layer along the air guide bottom surface 9b among a plurality of sub-channels divided by a plurality of support ribs 9a into a gap between the bottom of the frying basket 8 and the bottom of the frying tub 9, and then the food in the frying basket 8 is heated through the front basket air guide holes 8a and the rear basket air guide holes 8d at the bottom of the frying basket 8.

The isolation frame 12 is provided with a plurality of air guide holes. By setting the distribution and number of holes, the flow direction and distribution of the hot air are adjusted. The air guide holes on the isolation frame 12 are overlapped with the air guide holes of the fry basket to control the flow direction and the distribution of hot air. The isolation frame is formed in a modularized way by selecting two plates with air guide holes for forming the isolation frame 12 and splicing and inserting the plates with the partition plates together. The size and the range of hot air flow entering the front area and the rear area can be adjusted, and the hot air flow is suitable for processing requirements of different dishes.

The air moves upwards through the air guide holes and passes through the food to heat the food. The upwardly diffused hot air is sucked through the heat generating pipe 7 by the center hole 6b of the lower cover plate of the scroll. Thus, the hot air forms a reciprocating circulation in the air fryer and uniformly heats the food.

Although the embodiments disclosed in the present application are described above, the descriptions are only for the convenience of understanding the present application, and are not intended to limit the present application. It will be apparent to persons skilled in the relevant art that various modifications and variations can be made in the form and details of the disclosed embodiments without departing from the spirit and scope of the disclosure.
