AI Technical Summary
Existing air fryers have the drawback of a large temperature gradient between the upper and lower layers, resulting in better frying and baking of food on the upper layer but poorer frying and baking of food on the lower layer. In particular, they cannot fry and bake food on two or more layers evenly.
The oil collection grid adopts a tile-type structure, including an upper tile layer component and a lower tile layer component. The components are interspersed and staggered. The lower tile component has a concave groove to store oil droplets. Hot air can pass through the oil collection grid structure, and together with the upper and lower electric heating devices, a cross hot air flow is formed to achieve a balanced temperature distribution.
It improves the frying and baking effect of food in both the upper and lower layers, achieves the consistency of temperature on the upper and lower surfaces of the food, solves the problem of uneven frying and baking caused by temperature gradient between the upper and lower layers in the existing technology, and realizes the balanced frying and baking of two or more layers of food.

[0002] Figure 1 Fig. 1 is a schematic diagram of the main structure of an existing air-frying oven on the market, and the basic structure includes an oil receiving screen (100), a bottom layer frying screen (200), an upper layer frying screen (300), an electric heating device (400), a fan (500), a fan motor (600), and a control system and operation panel (700).
[0003] The air-frying oven with this structure has only the function of receiving oil drops or water drops in the bottom layer disc-shaped oil receiving screen (100), and does not have the function of allowing air flow to pass through the oil screen, so that the air-frying oven can only have the electric heating device (400) on the top, and relies on the rotation of the fan (500) to stir the air, so that the hot air flows downward along the side wall area of the air-frying oven, and then flows upward along the central area of the air-frying oven, forming a higher temperature on the upper layer of the frying pot, a lower temperature on the lower layer, and a higher temperature gradient between the upper and lower layers, thereby causing the upper surface of the food to have a better frying effect, and the lower surface of the food to have a poor frying effect, and especially, the air-frying oven cannot provide balanced frying for two layers or more of food.

DETAILED DESCRIPTION
[0040] The application will be further described below in combination with the drawings and examples. Specific example one:
[0041] As shown in Figure 7 : the main structure of this embodiment one includes the oven body 50, the frying grid 20, the upper electric heating device 30-1, the upper fan 30-1-1 and the motor 30-1-2, the bottom electric heating device 30-2-1, the lower fan 30-2-2 and the motor 30-2-3, and the control system and operation panel 40.
[0042] Referring to Figure 3 , the tile type oil receiving grid structure 10 of this embodiment adopts the upper tile layer assembly and the lower tile layer assembly of the grid structure, the upper tile layer assembly is composed of 9 upper tile pieces, and the upper tile piece is the upper layer strip-shaped tile 10-1-1; the lower tile layer assembly is composed of 10 lower tile pieces, and the lower tile piece is the lower layer strip-shaped tile 10-2-1.
[0043] For a large frying oven, each lower layer strip-shaped tile 10-2-1 of the lower tile layer assembly can be made to be slightly inclined downward at one end of the front or the rear, and another concave oil receiving groove is connected transversely below the inclined lower layer strip-shaped tile 10-2-1, so that the oil and water of each lower layer strip-shaped tile 10-2-1 can flow into the newly added oil receiving groove for collection, which is more convenient for cleaning.
[0044] The bottom electric heating device 30-2-1 and the lower fan 30-2-2 are arranged below the tile type oil receiving grid structure.
[0045] The frying process of this embodiment:
[0046] Place the food 21 into the fryer oven, select the frying temperature and time on the control panel, and start the fryer oven. The hot air flow 01 generated by the upper heating element diffuses from top to bottom, while the hot air flow 02 generated by the bottom heating element 30-2-1 diffuses from bottom to top through the tiled oil collection grid structure 10. The downward and upward hot air flows cross and converge in the middle space of the fryer oven, making the temperature of the upper, middle and lower layers of the oven more consistent. The upper, lower and surrounding surfaces of the food 21 are fried at a relatively uniform temperature.
[0047] 00 represents an oil droplet or a water droplet, 01 arrow represents a downward hot airflow generated by the upper heating element, and 02 arrow represents an upward hot airflow generated by the lower heating element.
[0048] Oil or water droplets 00 generated by the fried or grilled food 21 are deposited in the concave grooves of the lower tile assembly through the gaps in the upper tile assembly, and will not drip onto the bottom heating device 30-2-1.
[0049] After being fried and baked for a set time, the top, bottom and surrounding surfaces of the food 21 are all fried and baked to a relatively even degree, achieving high-quality frying and baking without the need for flipping.
[0050] After frying or baking, the tile-shaped oil collection grid structure 10 can be easily removed from the fryer oven, and the upper tile layer assembly 10-1 and the lower tile layer assembly 10-2 can be cleaned separately. Specific Implementation Example 2:
[0051] like Figure 8 As shown, in this embodiment, the tile-type oil collection grid structure is used in an air fryer. Its main structure includes a pot body 60, an air fryer basket 70, an upper electric heating device 30-1, an upper impeller 30-1-1 and a motor 30-1-2, a bottom electric heating device 30-2-1, a lower impeller 30-2-2 and a motor 30-2-3, and a control system and operation panel 80.
[0052] See Figures 6a to 6c In this embodiment, the overlapping oil receiving grid structure 10 adopts a rotary structure. The upper tile layer assembly 10-3 is composed of two upper tile pieces, the upper tile piece being the upper tile ring 10-3-1. The lower tile layer assembly 10-4 is composed of two lower tile pieces and one lower tile disc 10-4-2 with an upward opening, the lower tile piece being the lower tile ring 10-4-1.
[0053] The overlapping oil receiving grid structure 10 and the frying basket 70 adopt a separate structure.
[0054] Both the tile-shaped oil collection grid structure 10 and the frying basket 70 can be inserted into or removed from the rim of the air fryer.
[0055] The bottom electric heating device 30-2-1 is arranged below the tile type oil receiving structure.
[0056] For the present embodiment, if the depth of the frying basket is relatively shallow, only the bottom electric heating device can be arranged, and the fan and the fan motor can be omitted.
[0057] The oil drops or water drops 00 generated by the fried food 21 are retained in the concave groove and the center tile tray of the lower tile ring 10-4-1 via the interval of the upper tile ring 10-3-1, and cannot drip onto the bottom electric heating device 30-2-1.
[0058] Figure 8 In the figure, 00 represents oil drops or water drops, 01 represents the downward hot air flow generated by the upper electric heating assembly, and 02 represents the upward hot air flow generated by the bottom electric heating assembly.
[0059] After the frying is completed, the tile type oil receiving structure 10 can be taken out from the opening of the air fryer for cleaning.
[0060] The other frying processes of the present embodiment are almost the same as those of the first embodiment, and will not be described here.
[0061] It should be noted that the present application provides the preferred embodiments of the present application in the specification and the drawings, and is not limited to the embodiments described in the specification, and these embodiments are not additional limitations on the content of the present application, and the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Furthermore, the above technical features continue to be combined with each other, forming various embodiments not listed above, which are all considered to be within the scope of the present application; further, for those skilled in the art, the above description can be improved or changed, and all these improvements and changes should be within the protection scope of the appended claims of the present application.
