1. according to the air fryer, the center of the hot air assembly deviates from the center of the fryer assembly, and particularly, the distance from the center of the hot air assembly to the hinge center is smaller than the distance from the center of the fryer assembly to the hinge center, so that the distance from the center of the hot air assembly to the outer edge of the fryer assembly is increased, when the visible window is arranged around the hot air assembly, the distance from the region, located at the outer edge of the hot air assembly, of the visible window to the outer edge of the fryer assembly is increased, the visible area is increased, and therefore, on the premise that the proportion requirement of the hot air assembly to the fryer assembly is met, the effective utilization area of the visible window is guaranteed, and the. Moreover, the area of the visible window on the projection section is directly increased instead of increasing the visual angle by utilizing the angle of the space, so that a user can directly observe the state of the food materials in the fryer assembly through the visible window, and the food materials can be fully observed without changing the angle. Because the increase of the actual observation area of the visual window, the height that need not the rethread improvement lid increases vertical observation area, and the lid highly can reduce in vertical direction to make lid and holistic focus reduce, control and job stabilization nature to the complete machine can improve greatly. The distance between the center of the hot air assembly and the hinge center is reduced, the center of gravity of the cover body and the whole machine is also favorably controlled, when the cover body is opened or buckled, the center of the hot air assembly is small relative to the rotating radius of the hinge center, the rotating linear speed is small, the received torsion and torque are small, and a user can conveniently control the cover body by using small force. When the lid is in the open mode, hot-blast subassembly centre-to-centre distance is little, and is also little enough apart from the height of controlling the platform, and because the most quality of lid concentrates on hot-blast subassembly, the focus of lid also squints downwards thereupon to the stability of complete machine has further been promoted. The included angle of the connection of the projection of the center of the fryer component and the hinge center on the horizontal plane and the projection of the center of the hot air component and the hinge center on the horizontal plane is smaller, especially, the included angle is directly arranged on the same line, thus, the length and the area of the visual window which is positioned at the front part of the air fryer, namely one side of a user, are the largest, and the condition that the user can conveniently observe food materials in the fryer component from the visual window is ensured.

2. An outer window and an inner window are arranged at the same time, the outer window is obliquely arranged, and the inner window transversely extends to form a visual cavity by surrounding with the cover body. The inner viewing window is transversely extended, so that the space is not occupied at the vertical height, the whole height of the cover body can be set to be small enough, the height of the cover body can be fully compressed, the downward movement of the gravity center of the cover body and the whole machine is ensured, and the stability is improved; meanwhile, the size of the cover body and the size of the whole machine can be reduced, the whole machine is prevented from occupying more space, and great convenience is brought to the use and storage of consumers. Through setting up the visual chamber, until cutting off the heat exchange of frying pan subassembly inside and outside, avoid the outside high temperature of lid, prevent to cause the injury to the user. Meanwhile, the visible cavity can also avoid the condensation phenomenon caused by the internal and external temperatures, and the condition that the inside of the fryer assembly cannot be normally observed due to condensation is avoided. The outer window is obliquely arranged, the arrangement of the inner window and the bottom surface of the cover body is not influenced, the height of the cover body and the whole machine is not increased, and the outer window is obliquely arranged, so that the volume of the visible cavity is increased, the partition performance of the temperature is better, and the effect is better.

Be equipped with cold air fan in the installation cavity, can reduce the installation cavity device, avoid the heating member to see through the aviation baffle and to the high temperature that the heating leads to in the installation cavity, protect each device. The air inlet and the air outlet are further arranged, so that air convection is generated between the inside and the outside of the installation cavity, outside cold air can be injected into the installation cavity in time, inside hot air can be discharged through the air outlet, and the heat dissipation efficiency is ensured. The air intake sets up in the lateral wall, and the air outlet sets up in the back wall, because the inside air inlet of air intake, can not influence user's normal use, and the hot-blast of air outlet is discharged backward, can not influence the user and normally control the product equally. And the air inlet is far away from the air outlet, thereby avoiding the hot air at the air outlet from being sucked into the mounting cavity again and improving the cooling efficiency.

8. Lid and frame set up processing district and joining region, and the joining region is located processing district rear side, and the user directly controls processing district, for example place eat the material, control the machine, observe eating material etc. and directly control in processing district, and the joining region sets up in processing district rear side, and when the user opened the lid, the lid backward rotatory is in order to open completely fried pot subassembly, fried pot subassembly can not sheltered from, and user operating space is bigger, uses more conveniently. The radius of the fryer component is R, the distance between the center of the fryer and the hinge center is D, and D/R is more than or equal to 1.1 and less than or equal to 2. D/R's ratio sets up the undersize, then articulated center is too near apart from the fryer edge, is unfavorable for the setting of articulated shaft, and the installation between lid and the frame also has inconveniently to when the lid was opened, because articulated center is too near apart from interior pot edge, still be unfavorable for the user to controlling of interior pot, reduced user's use impression. The D/R ratio is set to be overlarge, the connecting area is arranged to be overlarge relative to the processing area, the larger space of the whole machine is occupied, the main devices of the air fryer are usually arranged in the processing area to meet the installation, and the overlarge connecting area does not have redundant installation requirements, so that the volume of the whole machine is increased. Simultaneously, pot distance is too big in the articulated centre-to-centre spacing, when opening the lid, inevitably causes hot-blast subassembly position to shift up for the focus of lid shifts up, and simultaneously, hot-blast subassembly's radius of rotation increase is unfavorable for controlling of lid stable, also makes the user need bigger operation radius space when controlling, controls the comfort level and reduces.

9. Further set up steam subassembly for the air is fried the pot and has the function of evaporating simultaneously, has enlarged the service function that the air was fried the pot, and increases to evaporate the function and need not increase the product volume very much, and the function increases swiftly, and the product practicality is better. The steam inlet of the steam delivery line is centrally located in the bottom wall of the fryer assembly such that the steam inlet is centrally located in the bottom wall of the fryer assembly and offset from the center of the hot air assembly. Firstly, steam enters the fryer assembly from the bottom wall, and the characteristic of the steam can move upwards, so that the steam entering the fryer assembly can be quickly diffused in the fryer assembly to fill the whole fryer assembly, and the processing efficiency is high; meanwhile, steam can not directly impact the hot air component on the body, the influence of the steam on the hot air component is prevented, and the steam can rapidly flow in the inner pot along the air flow by utilizing the air flow formed by the hot air component, so that the food material is heated, and the heating efficiency is high.

10. Set up the exhaust pipe way on the lid, the exhaust inlet is located the aviation baffle roof, and steam is ascending and is accomplished the processing back and discharge from the exhaust pipe way, has complied with the direction that steam naturally flows, even when the product only utilizes the function of evaporating, hot-blast subassembly is out of work, and heating member and fan can not drive and explode the inside heating of pot subassembly and vortex, and the heat and the flow direction of steam self also can satisfy the product to evaporating the support of function to heating efficiency can guarantee. And further, when the fan works, the air and the steam at the exhaust inlet can be blown away all around, more steam is pressed to circulate in the inner part of the fryer component, so that the pressure of the steam in the inner part of the fryer component is increased, a certain supercharging effect is achieved, and the heating efficiency of the steam is further improved. Exhaust import is apart from the distance at articulated center is less than the distance at hot-blast subassembly center-to-articulated center, like this, from the air explode a pot front side to articulated center on, set gradually explode a pot subassembly center (contain steam inlet), hot-blast subassembly center and exhaust import, steam is by importing to the export, can reserve sufficient time in exploding pot subassembly inside, has fully guaranteed the heating efficiency of steam.
