By adopting the above structure, on the one hand, because the first plate section 221 and the second plate section 222 are respectively arranged at two sides of the axis of the rotating shaft 21, in the process that the blade 22 rotates for a circle, the first plate section 221 and the second plate section 222 are more attached to the inner wall of the cooking cavity 51, so that the first plate section 221 and the second plate section 222 can successively stir the food materials in the cooking cavity 51 once, and the food is not easy to wind on the stirring blades 20. On the other hand, since the distance between the outer edge of the first plate 221 and the inner wall of the cooking cavity 51 is greater than the distance between the outer edge of the second plate 222 and the inner wall of the cooking cavity 51, the turning track of the outer edge of the first plate 221 is higher than the turning track of the outer edge of the second plate 222, so that the first plate 221 has a turning and frying effect on the upper layer food in the cooking cavity 51, the first plate 221 is responsible for pushing the high-level food to be flat, the second plate 222 is responsible for turning and frying the bottom food longitudinally, and the first plate 221 and the second plate 222 are matched to further improve the three-dimensional stirring effect of the stirring assembly on the food in the cooking cavity 51.

It should be noted that the distance between the outer edge of the first plate section 221 and the inner wall of the cooking cavity 51 refers to the distance between the outer edge of the first plate section 221 and the bottom wall of the cooking cavity 51, and the distance between the outer edge of the first plate section 221 and the side wall of the cooking cavity 51. The distance between the outer edge of the second plate section 222 and the inner wall of the cooking cavity 51 refers to the distance between the outer edge of the second plate section 222 and the bottom wall of the cooking cavity 51, and the distance between the outer edge of the second plate section 222 and the side wall of the cooking cavity 51. In the present embodiment, a distance between the outer edge of the first plate section 221 and the bottom wall of the cooking cavity 51 is greater than a distance between the outer edge of the second plate section 222 and the bottom wall of the cooking cavity 51, and a distance between the outer edge of the first plate section 221 and the sidewall of the cooking cavity 51 is greater than a distance between the outer edge of the second plate section 222 and the sidewall of the cooking cavity 51.

In the present embodiment, the stereoscopic stirring means: stirring leaf 20 carries out ascending stirring of circumference to the food in the culinary art chamber 51 of interior pot 50, and stirring leaf 20 vertically overturns the stirring to the food in the culinary art chamber 51 for the food in the culinary art chamber 51 both overturns along the circumference of culinary art chamber 51, and along the vertical upset of culinary art chamber 51 again, forms the effect of solid upset. That is, while ensuring the circumferential rotation of the stirring vanes 20, the secondary three-dimensional stir-frying of the longitudinal side portions of the stirring vanes 20 is realized, and the stir-frying of the side portions is in the longitudinal circular motion of a displacement shape while the bottom portion rotates, so the motion is in a parabolic shape instead of a simple circular motion, thereby achieving the real three-dimensional stir-frying.

As shown in fig. 9, the second plate section 222 is disposed offset with respect to the first plate section 221 in the circumferential direction of the drum 10. Adopt the blade 22 of above-mentioned structure, when the blade 22 revolves around the vertical axis of the rotary drum 10 and revolves around the horizontal axis of the rotary shaft 21, because the second plate section 222 is for the first plate section 221 skew setting in the circumferential direction of rotary drum 10, on the one hand, the outside border of second plate section 222 can be along the length direction of second plate section 222 gradually with the inner wall cooperation of culinary art chamber 51, not the whole outside border of second plate section 222 all directly with the inner wall contact of culinary art chamber 51, make second plate section 222 progressively promote when eating the material contact with the bottom, reduce the card and stop the problem, on the other hand, after the skew setting, the size of blade 22 in the direction of perpendicular to rotary shaft 21 axis further increases, avoid food to twine on blade 22, and under the prerequisite that does not increase the volume of blade 22, increase the three-dimensional stirring scope of blade 22, thereby make the edible material in the culinary art chamber 51 obtain better three-dimensional stirring effect.

It should be noted that the second plate section 222 is offset from the first plate section 221 in the circumferential direction of the drum 10, which means that the second plate section 222 is offset from the first plate section 221, i.e. the extending direction of the second plate section 222 forms an angle with the extending direction of the first plate section 221, so that when the blades 22 rotate, the outer edge of the second plate section 222 will gradually fit with the inner wall of the cooking cavity 51 along the length direction of the second plate section 222, rather than the entire outer edge of the second plate section 222 simultaneously contacting with the inner wall of the cooking cavity 51.

As shown in fig. 1, the first plate section 221 and the second plate section 222 are both arc-shaped, and the middle portions of the first plate section 221 and the second plate section 222 are both protruded in a direction away from the axis of the rotating shaft 21. So that the arc-shaped first plate section 221 and the arc-shaped second plate section 222 form a similar circular turnover structure during the rotation of the blade 22 by one turn, so that the food is not easily wound on the stirring blade 20.

It should be noted that, as shown in fig. 1 and fig. 2, in this embodiment, the middle portion of the first plate section 221 and the middle portion of the second plate section 222 are not provided with only a portion of a convex structure, but the entire sections of the first plate section 221 and the second plate section 222 are both arc-shaped structures, so that in the process of rotating the blade 22 by one circle, the arc-shaped first plate section 221 and the arc-shaped second plate section 222 form a turnover structure similar to a circle.

Specifically, in the present embodiment, during the rotation of the blade 22 by one rotation, the arc-shaped first plate section 221 and the arc-shaped second plate section 222 form an inverted structure similar to an ellipse, and the extending direction of the axis of the rotating shaft 21 is the short axis of the ellipse.

By adopting the included angle α in the above angle range, when the blade 22 revolves around the vertical axis of the drum 10 and rotates around the horizontal axis of the rotating shaft 21, on one hand, if the included angle α is too small (smaller than 25 °), the second plate segment 222 cannot be pushed gradually when contacting with the bottom food material, and the problem of jamming is easily caused, and on the other hand, if the included angle α is too large (larger than 65 °), the stirring range of the blade 22 can be reduced, and the stirring effect is further influenced.

Specifically, the included angle α between the plane of the outer side wall of the second plate section 222 and the vertical plane of the rotating shaft 21 may be 25 °, 35 °, 45 °, 55 °, 65 ° or any other value between 25 ° and 65 °.

As shown in fig. 1, 5, 6, 7 and 8, the blade 22 further includes a third plate segment 223, the third plate segment 223 is connected to an end of the second plate segment 222 far from the first plate segment 221, and the third plate segment 223 is bent relative to the second plate segment 222 in a direction toward the axis of the rotating shaft 21. By adopting the third plate segment 223, when the blade 22 revolves around the vertical axis of the drum 10 and rotates around the horizontal axis of the rotating shaft 21, the third plate segment 223 revolves around the vertical axis of the drum 10 and revolves around the horizontal axis of the rotating shaft 21, and the bent third plate segment 223 is arranged at the end of the second plate segment 222 far away from the first plate segment 221, so that when the second plate segment 222 stirs the food material, the food material falling off from the second plate segment 222 can be secondarily stirred by using the third plate segment 223, and the stirring effect of the blade 22 on the food material is improved.
