All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 12, an embodiment of the present invention provides a stirring assembly, which is disposed in an inner pot 50, and the stirring assembly includes a rotating drum 10, a stirring blade 20 and a transmission structure 30, the rotating drum 10 is rotatably disposed in a cooking cavity 51 of the inner pot 50 about a vertical axis thereof, the stirring blade 20 includes a rotating shaft 21 and a blade 22 disposed on the rotating shaft 21, the rotating shaft 21 transversely penetrates through a side wall of the rotating drum 10, the transmission structure 30 is disposed in the rotating drum 10, and the transmission structure 30 can drive the rotating shaft 21 to rotate about a horizontal direction, wherein the blade 22 includes a first plate section 221 and a second plate section 222, a first end of the first plate section 221 is connected to the rotating shaft 21, a second end of the first plate section 221 is connected to one end of the second plate section 222, the first plate section 221 and the second plate section 222 are respectively located on two sides of the axis of the rotating shaft 21, an outer edge of the second plate section 222 is engaged with an inner wall of the cooking cavity 51, and a distance between the outer edge of the first plate section and the inner wall of the cooking cavity 51 is greater than a distance between the outer edge of the second plate section 222 and the inner wall of the cooking cavity 51.

By applying the technical scheme of the invention, the stirring assembly comprises the rotary drum 10, the stirring blade 20 and the transmission structure 30, when the rotary drum 10 rotates, the rotary drum 10 drives the stirring blade 20 to revolve around the vertical axis of the rotary drum 10, and the transmission structure 30 can drive the rotary shaft 21 to rotate around the horizontal direction, so that the blades rotate in the horizontal direction while revolving along with the rotary drum 10 in the circumferential direction, that is, the stirring blade 20 can be used for stir-frying food materials in the cooking cavity 51 in the circumferential direction while stir-frying the food materials in the vertical direction, and further a three-dimensional stirring effect is formed, and the stirring effect of the stirring assembly on food is improved. 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 section 221 and the inner wall of the cooking cavity 51 is greater than the distance between the outer edge of the second plate section 222 and the inner wall of the cooking cavity 51, the turning track of the outer edge of the first plate section 221 is higher than the turning track of the outer edge of the second plate section 222, so that the first plate section 221 has a stir-frying effect on the upper food in the cooking cavity 51, the first plate section 221 is responsible for pushing the high-level food to be flat, the second plate section 222 is responsible for longitudinally stir-frying the food at the bottom of the pot, and the first plate section 221 and the second plate section 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 parts of the stirring vanes 20 is realized, and the stir-frying of the side parts is in the longitudinal circular motion of a displacement shape while the bottom part rotates, so the motion of the stir-frying is parabolic instead of 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, so that the food is not easily wound on the stirring vane 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.

As shown in fig. 1, 2, 5, 6, 8 and 9, the angle α between the plane of the outer side wall of the second plate section 222 and the vertical plane of the rotation shaft 21 is between 25 ° and 65 °. 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 where the outer side wall of the second plate section 222 is located and the vertical plane where the rotating shaft 21 is located may be 25 °, 35 °, 45 °, 55 °, 65 °, and 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 away from the first plate segment 221, and the third plate segment 223 is bent with respect 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, far away from the first plate segment 221, of the second plate segment 222, so that when the second plate segment 222 stirs food materials, the food materials falling off from the second plate segment 222 can be secondarily stirred by the third plate segment 223, and the stirring effect of the blade 22 on the food materials is improved.
