Wherein, the even heat plate 12 is installed in the cooking cavity along the vertical direction, and divides the inside of the cooking cavity into a cooking cavity 16 and an air inlet cavity 14 along the left and right direction. The heating modules 2 are located at the left and right sides of the cooking cavity. The fan assembly 3 is mounted at the bottom of the cooking cavity. Specifically, the method comprises the following steps: the heating module 2 comprises a heating chamber 22 and a heating device 24 arranged in the heating chamber 22, the heating device 24 being adapted to heat air in the heating chamber 22. A first air duct 6 is arranged between the heating cavity 22 and the air inlet cavity 14, the first air duct 6 is an air inlet channel, and air heated in the heating cavity 22 can enter the air inlet cavity 14 through the first air duct 6 and then flow into the cooking cavity 16 from the air inlet cavity 14 through the heat-homogenizing plate 12. A second air duct is arranged between the cooking chamber 16 and the heating chamber 22, and the second air duct is an air return channel. The air heated by the food material in the cooking chamber 16 can pass through the second air duct to the heating chamber 22 and then be heated again by the heating means 24 in the heating chamber 22, so that a circulation of air can be completed.

Other configurations of the air fryer can be found in the first embodiment and will not be described herein.

In any of the above embodiments, as shown in fig. 4, the plurality of air holes 122 are evenly spaced on the soaking plate 12.

In this embodiment, the plurality of air holes 122 are evenly spaced to enable the air passing through the heat spreader 12 to enter the cooking cavity 16 evenly, thereby achieving air dispersion. Furthermore, the plurality of air holes 122 are distributed on the whole heat uniforming plate 12, and the total area of the plurality of air holes 122 occupies more than half of the area of the whole heat uniforming plate 12, so that the total area of the air holes 122 can be ensured, and the air output can be ensured.

For the scheme that a plurality of air holes 122 are uniformly distributed on the uniform heat disk 12 at intervals, the application provides the following three specific embodiments:

detailed description of the preferred embodiment

As shown in fig. 4, the plurality of air holes 122 are distributed in a rectangular array on the soaking plate 12, at least 3 air holes 122 are arranged in the soaking plate 12 along the transverse direction, and the air outlet area of all the air holes 122 along the transverse direction is gradually reduced from two ends to the middle.

In this embodiment, the plurality of air holes 122 are distributed in a rectangular array on the soaking plate 12, that is, the plurality of air holes 122 are arranged in multiple rows and columns on the soaking plate 12, this distribution mode is preferentially suitable for the rectangular plate structure, and the arrangement mode of the air holes 122 can make the air volume distribution of the soaking plate 12 in four directions, front, back, left and right, more uniform, so that the hot air can be uniformly dispersed to different parts of the food material, the problems of excessive heating and insufficient heating of parts of the food material due to the fact that the hot air is easily gathered at the local part of the food material in the prior art are solved, and the taste of the food material after cooking is ensured to the maximum extent, and the user experience is improved.

Furthermore, considering the influence of different air outlet positions, the air outlet area of the air holes 122 in the transverse direction or the vertical direction can be gradually reduced from the two ends to the middle, so that the opening areas of the air holes 122 at the two ends in the first direction are larger, the opening area of the air holes 122 in the middle is smaller, and the air outlet uniformity in the transverse direction is ensured.

Further, as shown in fig. 4, at least more than 3 air holes 122 are arranged on the soaking plate 12 along the vertical direction, and the air outlet area of all the air holes 122 along the vertical direction is gradually reduced from one end to the other end.

In this embodiment, the air outlet area of the air holes 122 in the second direction, for example, the vertical direction, may be gradually decreased from one end to the other end, for example, from front to back, to ensure the uniformity of the air outlet in the second direction, considering the influence of the air outlet position.

In a variation of the first embodiment: the plurality of air holes 122 are distributed in a rectangular array on the uniform heat plate 12, at least more than 3 air holes 122 are arranged in the uniform heat plate 12 along the vertical direction, and the air outlet area of all the air holes 122 along the vertical direction is gradually reduced from two ends to the middle. At least more than 3 air holes 122 are arranged on the heat equalizing disc 12 along the transverse direction, and the air outlet area of all the air holes 122 along the transverse direction is gradually reduced from one end to the other end.

The second embodiment is as follows: (not shown in this embodiment) the plurality of air holes 122 are distributed on a plurality of concentric circles centered on the center of the thermal distribution plate 12, i.e., in this aspect, the plurality of air holes 122 are distributed in a circular array on the thermal distribution plate 12.

Further, the air outlet area of the air holes 122 closer to the center of the circle is smaller, and further, the air holes 122 on the plurality of concentric circles are arc-shaped holes or center holes.

The third concrete embodiment: (not shown in this embodiment) a plurality of air holes 122 are arranged in a cross pattern on the soaking plate 12.

In another embodiment, the spacing between the plurality of air holes 122 is varied according to the location, i.e. the plurality of air holes 122 are not evenly spaced on the heat distribution plate 12. Specifically, the method comprises the following steps: the distance between the wind holes 122 at the middle part of the heat uniforming plate 12 is smaller, and the distance between the wind holes 122 at the edge of the heat uniforming plate 12 is larger.

In another specific embodiment, (not shown in this embodiment) the plurality of air holes 122 each include a kidney-shaped hole having a width of 1mm to 20 mm. Therefore, the problem that the air outlet distribution is too concentrated is avoided because the area of a single air hole 122 is too large.

In a third specific embodiment, (not shown in this figure) the plurality of air holes 122 are a combination of circular holes and kidney-shaped holes, wherein the kidney-shaped holes have a width of 1mm-20 mm. The diameter of the circular hole is 0.5mm-20 mm. In the specific design, a plurality of circular holes with smaller opening areas can be arranged in the middle of the uniform heat plate 12, and a plurality of kidney-shaped holes with smaller opening areas are arranged around the uniform heat plate 12. That is, in the present application, besides adjusting the uniformity between different air outlet positions according to the opening area and the distance of the air holes 122, the holes with different shapes can be arranged at different air outlet positions, so as to ensure the uniformity of air outlet at each position through the holes with different shapes.
