[0002] In the related art, cooking appliances such as air fryers usually have a stirring paddle installed in the inner pot for stirring and tumbling the ingredients so that the ingredients are heated evenly. The stirring paddle is mainly used to stir and tumble small-grained ingredients such as French fries, peanuts, and popcorn chicken. However, when the stirring paddle is stirring small-grained ingredients, it is easy for the sharp-cornered ingredients to be pressed between the stirring paddle and the bottom wall of the inner pot, and rotate synchronously with the stirring paddle, which causes the friction between the ingredients and the inner bottom wall of the inner pot to be too large, causing the coating to fall off, and reducing the performance of the inner pot. Utility Model Content

[0003] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0004] To this end, an embodiment of the utility model proposes an inner pot assembly, which has the advantages of a stirring paddle pressing and driving the food to contact and rub the inner pot, thereby reducing the risk of the coating on the inner pot falling off, and the inner pot has stable performance and a long service life.

[0005] The embodiment of the utility model also provides an air fryer.

[0006] The inner pot assembly of the embodiment of the utility model includes a stirring paddle and an inner pot; the stirring paddle includes a central column and blades, the central column is rotatably arranged in the inner pot, the blades include a main rib and a tumbling portion, the first end of the main rib is connected to the central column, the second end of the main rib is connected to the tumbling portion, the tumbling portion is adjacent to the inner wall of the inner pot and is used to tumble food, the distance between any position of the lower edge of the main rib and the tumbling portion and the inner bottom wall of the inner pot is d, wherein 0<d≤0.5mm.

[0007] According to the inner pot assembly of the embodiment of the utility model, the central column is pivotally connected to the inner pot, and the central column rotates relative to the inner pot to drive the main ribs and the rolling part to make circular motion, wherein the rolling part realizes the rolling of the food during the motion, and the main ribs push the food to move so that the food moves to a position adjacent to the inner wall of the inner pot under the guidance and centrifugal action of the main ribs, so as to be repeatedly rolled by the rolling part. Among them, by setting the distance between any position of the lower edge of the main ribs and the rolling part and the inner bottom wall of the inner pot to be greater than 0 and less than or equal to 0.5mm, on the one hand, the main ribs and the rolling part are prevented from directly contacting the inner bottom wall of the inner pot and scratching and damaging the coating on the inner pot, and on the other hand, the probability of the food with sharp corners being stuck between the main ribs and the inner bottom wall of the inner pot, and between the rolling part and the inner bottom wall of the inner pot is effectively reduced, thereby effectively preventing the rolling part and the main ribs from pressing the food downward and driving the food to scratch and damage the coating on the inner pot, and the use performance and service life of the inner pot are higher.

[0008] Optionally, the blade further comprises a reinforcing rib, a first end of the reinforcing rib is connected to the central column, a second end of the reinforcing rib is connected to the tumbling portion, and an upper edge of the reinforcing rib is connected to the main rib.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0028] Combine the following Figure 1-Figure 6 An inner pot assembly according to an embodiment of the utility model is described.

[0029] The inner pot assembly according to the embodiment of the utility model includes a stirring paddle 1 and an inner pot 2. The stirring paddle 1 includes a central column 11 and a blade 12, and the central column 11 is rotatably arranged in the inner pot 2. The blade 12 includes a main rib 121 and a rolling portion 122, the first end of the main rib 121 is connected to the central column 11, and the second end of the main rib 121 is connected to the rolling portion 122, and the rolling portion 122 is adjacent to the inner wall of the inner pot 2 and is used to roll the food. The distance between any position of the lower edge of the main rib 121 and the rolling portion 122 and the inner bottom wall of the inner pot 2 is d, where 0<d≤0.5mm.

[0030] According to the inner pot assembly of the embodiment of the utility model, the central column 11 is pivotally connected to the inner pot 2, and the central column 11 rotates relative to the inner pot 2 to drive the main ribs 121 and the rolling part 122 to make circular motion, wherein the rolling part 122 realizes the rolling of the food during the movement, and the main ribs 121 push the food to move so that the food moves to a position adjacent to the inner wall of the inner pot 2 under the guidance of the main ribs 121 and the centrifugal action, so as to be repeatedly rolled by the rolling part 122. Among them, by setting the distance between any position of the lower edge of the main rib 121 and the rolling part 122 and the inner bottom wall of the inner pot 2 to be greater than 0 and less than or equal to 0.5 mm, on the one hand, it is avoided that the main rib 121 and the rolling part 122 are in direct contact with the inner bottom wall of the inner pot 2 and scratch and damage the coating on the inner pot 2, and on the other hand, it is effectively reduced The probability of food with sharp corners getting stuck between the main rib 121 and the inner bottom wall of the inner pot 2, and between the rolling part 122 and the inner bottom wall of the inner pot 2, thereby effectively avoiding the rolling part 122 and the main rib 121 Pressing the food downward and driving the food to scratch and damage the coating on the inner pot 2, the performance and service life of the inner pot 2 are improved.

[0031] It should be noted that the side surface of the main rib 121 for pushing the food is bent and inclined from bottom to top in the rotation direction away from the main rib 121 , that is, the side surface forms an obtuse angle with the inner bottom wall of the inner pot 2 .

[0032] In some embodiments, Figure 2-Figure 4 and Figure 6 As shown, the blade 12 further includes a reinforcing rib 123 , a first end of the reinforcing rib 123 is connected to the central column 11 , a second end of the reinforcing rib 123 is connected to the rolling portion 122 , and an upper edge of the reinforcing rib 123 is connected to the main rib 121 .

[0033] That is, the reinforcing rib 123 is connected to each of the main rib 121, the rolling portion 122 and the central column 11, thereby effectively improving the deformation resistance of the main rib 121 and the rolling portion 122, ensuring that the main rib 121 and the rolling portion 122 have a stable pushing and rolling effect on the food, and also ensuring that a stable gap is maintained between the main rib 121 and the rolling portion 122 and the inner bottom wall of the inner pot 2.

[0034] In some embodiments, Figure 6 As shown, the distance between any position of the lower edge of the reinforcing rib 123 and the inner bottom wall of the inner pot 2 is D, wherein 6.3 mm ≤ D ≤ 8 mm.

[0035] This size can allow most small-sized food to pass through, effectively preventing the food from getting stuck between the reinforcing ribs 123 and the inner bottom wall of the inner pot 2, causing the food to scratch and damage the coating of the inner pot 2 under the drive of the reinforcing ribs 123. At the same time, this size can also produce a certain amount of turbulence on the accumulated food, thereby improving the tumbling effect of the food in the inner pot 2.

[0036] For example, the distance D between any position of the lower edge of the reinforcing rib 123 and the inner bottom wall of the inner pot 2 is 6.3 mm, 7 mm or 8 mm. Taking 1 / 4 French fries (1 / 4 inch French fries) as an example, the size of the French fries is smaller than the distance between the lower edge of the reinforcing rib 123 and the inner bottom wall of the inner pot 2, and the French fries are not easily stuck between the reinforcing rib 123 and the inner bottom wall of the inner pot 2.

[0037] In some embodiments, both the main rib 121 and the reinforcing rib 123 are bent and extended along the rotation direction of the central column 11 , and the reinforcing rib 123 is located on the radially inward side of the main rib 121 along the central column 11 .

[0038] By setting the main ribs 121 and the reinforcing ribs 123 to bend and extend along the rotation direction of the central column 11, the main ribs 121 can better guide and push the food when performing circular motion, and it is more convenient for the food in the middle of the inner pot 2 to move toward the inner wall of the inner pot 2, so as to achieve the comprehensive and uniform rolling of the food in the inner pot 2 by the tumbling part 122. The reinforcing ribs 123 are arranged on the radially inward side of the main ribs 121 along the central column 11, which effectively prevents the reinforcing ribs 123 from affecting the function of the main ribs 121, and can also disturb the food inside the main ribs 121, effectively preventing the food from piling up and affecting the cooking efficiency.

[0039] For example, Figure 3 and Figure 6 As shown, the main ribs 121 and the reinforcing ribs 123 are both plate-shaped structures, the upper edge of the main ribs 121 is connected to the upper edge of the reinforcing ribs 123, and the distance between the main ribs 121 and the reinforcing ribs 123 in the radial direction of the central column 11 gradually increases downward along the axial direction of the central column 11. That is, the main ribs 121 and the reinforcing ribs 123 form a V-shaped groove with an opening facing downward, which effectively prevents food from being stuck between the main ribs 121 and the reinforcing ribs 123 and causing insufficient heating.

[0040] In some embodiments, Figure 3 As shown, at least three protrusions 13 are provided on the lower end surface of the central cylinder 11, and the surface of the protrusions 13 is a spherical surface, and all the protrusions 13 are arranged at intervals along the circumference of the central cylinder 11. That is, the central cylinder 11 abuts against the inner bottom wall of the inner pot 2 through the hemispherical protrusions 13, so that the contact between the stirring paddle 1 and the inner bottom wall of the inner pot 2 is point contact, and the sliding friction between the two is smaller, thereby effectively reducing the probability of the protrusions on the inner pot 2 being scratched and damaged.

[0041] For example, Figure 3 As shown, the protrusions 13 are hemispherical and there are four of them. The four protrusions 13 are arranged at equal intervals along the circumference of the central column 11 .

[0042] In some embodiments, the lower end face of the central column 11 is provided with a first guide hole 111, the middle portion of the bottom wall of the inner pot 2 is bent upward to form a first boss 21, and the first boss 21 is in clearance with the first guide hole 111. Alternatively, the lower end face of the central column 11 is provided with a second boss extending downward, the middle portion of the bottom wall of the inner pot 2 is bent downward to form a second guide hole, and the second boss is in clearance with the second guide hole. By setting the clearance between the first boss 21 and the first guide hole 111, or by setting the clearance between the second boss and the second guide hole, the radial position limitation of the central column of the inner pot 2 is effectively ensured, so that the rotation of the central column in the inner pot 2 is stable and reliable.

[0043] For example, Figure 5 and Figure 6 As shown, the lower end surface of the central column 11 is provided with a first guide hole 111, and the middle part of the bottom wall of the inner pot 2 is bent upward to form a first boss 21, and the first boss 21 is loosely matched with the first guide hole 111, and the area of ​​the cross-sectional outer contour of the first boss 21 gradually decreases upward along the axial direction of the central column 11. That is, the outer contour of the first boss 21 is generally a frustum, thereby making it easier to sleeve the first guide hole 111 on the central column 11 on the first boss 21, and the assembly of the stirring paddle 1 on the inner pot 2 is convenient and quick.

[0044] In some embodiments, Figure 1 and Figure 4As shown, the upper surface of the rolling portion 122 is formed with a slope surface 1221 and a rolling surface 1222, the rolling surface 1222 and the slope surface 1221 are arranged along the rotation direction of the central column 11, the height of the slope surface 1221 gradually decreases along the rotation direction of the central column 11, and the height of the rolling surface 1222 gradually increases along the rotation direction of the central column 11. The slope surface 1221 is used to push the food, so that the food can roll under the guidance of the slope surface 1221, and the food can roll down along the rolling surface 1222 after reaching the top of the slope surface 1221, so that the food can achieve a better rolling effect.

[0045] For example, Figure 4 As shown, in order to better guide the food, the inclination angle of the slope surface 1221 relative to the horizontal plane is set to be an obtuse angle, such as an inclination angle greater than 135°. At the same time, in order to achieve a better rolling effect, the inclination angle of the rolling surface 1222 relative to the horizontal plane is set to be an obtuse angle and smaller than the inclination angle of the slope surface 1221 relative to the horizontal plane.
