With continued reference to fig. 1-3, an exemplary embodiment of the present disclosure provides a pot assembly 1, the pot assembly 1 including an outer pot 11, an inner pot 12, a fry basket 13, and a driven fan 14, the outer pot 11 having an inner pot receiving cavity in which the inner pot 12 is disposed. The inner pot 12 is provided with a cooking cavity, the frying basket 13 is arranged in the cooking cavity, and the frying basket 13 is used for supporting food materials to be cooked.

Specifically, as an example, the bottom wall of the fry basket 13 is provided with ventilation holes penetrating the top and bottom surfaces of the bottom wall, the ventilation holes being uniformly arranged on the bottom wall of the fry basket 13. Optionally, the basket 13 may further include a basket sidewall extending upward from an outer periphery of the bottom wall along an axial direction of the inner pot 12, preventing food materials from being disposed outside the bottom wall of the basket 13 to block the air passage, thereby improving smoothness of flow of hot air and uniformity of heat in the cooking chamber.

By way of example, but not limitation, the support blocks 16 are a plurality and the plurality of support blocks 16 are attached to the side wall of the fry basket at spaced intervals along the circumference of the inner vessel 12.

The driven fan 14 is rotatably connected to the lower side of the basket 13, and in particular, the driven fan 14 is disposed in a space below the basket 13. In this embodiment, the driven fan 14 does not need to be provided with a power source, and under the blowing of the driving fan 22, the hot air has a predetermined flowing speed, and when the hot air acts on the driven fan 14, the driven fan 14 can be pushed to rotate, so that the hot air circulation below the frying basket 13 is quickened, the hot air circulation in the cooking cavity is quickened, the heating uniformity of the food is improved, and the cooking taste of the food is improved.

Specifically, the driven fan 14 includes first blades 141 and second blades 142 alternately arranged along the circumferential direction of the inner pan 12, and the second blades 142 are provided with blade notches 144, and the blade notches 144 penetrate through two side walls of the second blades 142 along the circumferential direction of the inner pan 12.

In this embodiment, the second fan 142 is provided with the fan notch 144, so that hot air can be collected and accelerated at the fan notch 144, thereby improving the heating uniformity of the food in the cooking cavity.

As an example, to further improve the heating uniformity of the food material, the second fan blade 142 extends along the axial direction of the inner pan 12, the fan blade notch 144 is disposed near the center of the inner pan 12 along the radial direction of the inner pan 12, and the fan blade notch 144 is disposed recessed upward from the bottom end of the second fan blade 142.

In this embodiment, by disposing the fan blade notch 144 near the center of the inner pan 12, the hot air is guided to flow toward the center side of the inner pan 12 by the second fan blade 142 disposed along the axial direction of the inner pan 12, and is concentrated at the position of the fan blade notch 144 and passes through the second fan blade 142, the first fan blade 141 and the second fan blade 142 are alternately disposed, and the hot air passing through the second fan blade 142 via the fan blade notch 144 is concentrated on the first fan blade 141 and is guided toward the center by the first fan blade 141.

The present disclosure guides a portion of hot air toward the center of the inner pan 12 through the cooperation of the first fan blade 141 and the second fan blade 142, improving the flow rate of the hot air, and improving the heating uniformity of the cooking food material.

For convenience of description, the embodiment is illustrated with the fan blade notch 144 being disposed in an upward recess from the bottom end of the second fan blade 142, but not limited thereto, and the fan blade notch 144 may be disposed in a middle position of the second fan blade 142 along the axial direction of the inner pot 12, or may be disposed in a downward recess from the top end of the second fan blade 142, as required.

Referring to fig. 2 and 5, in order to further improve the heating uniformity of the food material, the second fan blades 142 have a first height along the axial direction of the inner pan 12, and the fan blade notches 144 have a second height along the axial direction of the inner pan 12, the second height being greater than half of the first height.

The larger the size of the fan blade notch 144 is, the more the hot air passes through the fan blade notch 144, and the hot air gathers from the radial outer edge to the radial inner edge of the inner pot 12, so that the phenomenon that the hot air is concentrated on the radial outer edge side and cannot contact with food is avoided, and the cooking uniformity of the food is improved. If the second height of the fan blade gap 144 is too small, the throughput of hot air is insufficient, and the accelerating effect of hot air is not obvious, thereby resulting in insufficient uniformity of hot air along the radial direction of the inner pot 12.

With continued reference to fig. 2, 4 and 5, in an exemplary embodiment of the present disclosure, the second fan blade 142 extends in an arc shape from the center of the driven fan 14 to the circumferential edge, the second fan blade 142 has a first length along the extending direction of the second fan blade 142, the fan blade notch 144 has a second length along the extending direction of the second fan blade 142, the second length is not less than 1/3 times the first length, and the second length is not more than 2/3 times the first length. The second fan blades 142 in this embodiment extend in an arc from the center of the driven fan 14 to the circumferential edge to accommodate the helically rotating hot air.

Further, when the second length is smaller than 1/3 of the first length, the second length is too small, which results in too small a size of the fan blade gap 144, and insufficient hot air passing through the fan blade gap 144, which results in insufficient uniformity of hot air. When the second length is greater than the first length of 2/3 times, the second length is too large, which results in oversized fan blade gap 144, and acceleration of hot air passing through the fan blade gap 144 is not obvious, which is unfavorable for uniformity of hot air.

As an example, the driven fan 14 further includes a blade middle cylinder 143, the first blade 141 is fixed to the blade middle cylinder 143 along a radial inner end of the inner pot 12, the radial inner end of the first blade 141 is disposed at an angle to an axis of the blade middle cylinder 143, the second blade 142 is fixed to the blade middle cylinder 143 along a radial inner end of the inner pot 12, and the radial inner end of the second blade 142 is disposed parallel to the axis of the blade middle cylinder 143.

In order to enable the driven fan 14 to smoothly rotate, the driven fan 14 is prevented from interfering with the movement of the frying basket 13, specifically, the top end surface of the first fan blade 141 is parallel to the bottom wall of the frying basket 13, so that hot air is uniformly guided upwards, and the uniformity of hot air in the cooking cavity is improved. A predetermined interval is provided between the top end surface of the first fan blade 141 and the fry basket 13 as needed, but not limited thereto.

Further, the bottom end surface of the first fan blade 141 is parallel to the bottom wall of the inner pot 12, and the distance between the bottom end surface of the first fan blade 141 and the bottom wall of the inner pot 12 is not greater than 5mm, so as to guide the hot air in the space below the frying basket 13 upwards as much as possible, and improve the energy utilization rate.

If the distance between the bottom end surface of the first fan blade 141 and the bottom wall of the inner pot 12 is greater than 5mm, the gap is excessively large, and the flow guiding effect of the driven fan 14 is deteriorated, which is not beneficial to uniformity of hot air in the cooking cavity. Optionally, the distance between the bottom end surface of the first fan blade 141 and the bottom wall of the inner pan 12 may be 5mm,4mm,3mm,2mm or 1mm, but is not limited thereto.

Optionally, the radial inner edge of the first fan blades 141 has an arc length smaller than that of the radial outer edge of the first fan blades 141, so that each first fan blade 141 is formed into a fan shape with an outer edge larger than an inner edge, so as to improve the guiding effect of hot air and improve the uniformity of hot air in the cooking cavity.

Referring to fig. 5, in order to further improve the hot air guiding performance of the first fan blade 141, the hot air is facilitated to flow inwards and upwards from the outer periphery of the cooking cavity, the first fan blade 141 extends from the fan blade middle barrel 143 to the outer periphery of the inner pot 12 in an arc surface, a tangent line at the position of the first point a on the arc surface has a first included angle with the horizontal direction, a second point B on the arc surface is positioned at the radial outer side of the inner pot 12 in the first point a, a tangent line at the position of the second point B has a second included angle with the horizontal direction, and the second included angle is smaller than the first included angle. As an example, the first point a and the second point B may be two points on an intersecting line of a plane passing through the axis of the driven fan 14 and the arc surface, and the radial distance of the second point B from the axis of the driven fan 14 is greater than the radial distance of the first point a from the axis of the driven fan 14.

Further, the third point C on the cambered surface and the first point a are located on the cylindrical cambered surface where the same radius of the inner pot 12 is located, that is, the first point a and the third point C are any two points on the intersecting line of the same cylinder and the cambered surface, the axis of the driven fan 14 coincides with the axis of the cylinder, the third point C is located above the first point a along the axial direction of the inner pot 12, a third included angle is formed between a tangent line at the position where the third point C is located and the horizontal direction, and the third included angle is larger than the first included angle. As an example, the first point a and the third point C are disposed on different radii of the same cylinder, the axis of the driven fan 14 coincides with the axis of the cylinder, and the radial distance from the third point C to the axis of the driven fan 14 is equal to the radial distance from the first point a to the axis of the driven fan 14.

In addition, the inner ring of the bearing 152 may be sleeved on the outer wall of the fan middle cylinder 143, and the supporting shaft 151 is sleeved outside the outer ring of the bearing 152, but not limited thereto.

To facilitate maintenance or cleaning of driven fan 14, bearing assembly 15 further includes a knob 154, knob 154 being threadably coupled to the top end of support shaft 151 such that support shaft 151 is secured to fry basket 13. In this embodiment, the support shaft 151 and the knob 154 are in threaded fit to form detachable connection, so that the driven fan 14 is detachably connected to the frying basket 13, and the driven fan 14 is detached and separated when the frying basket 13 is cleaned or the driven fan 14 is cleaned, thereby avoiding the operator from being scratched due to accidental rotation of the driven fan 14 in the cleaning process, and improving the use safety of the pot body assembly 1.

As an example, the knob 154 is provided with an operating handle to facilitate an operator to screw the knob 154 with respect to the support shaft 151, for example, but not limited to, the knob 154 includes a pair of operating handles protruding upward symmetrically arranged such that the knob 154 is generally formed in a rabbit-head shape, the pair of operating handles symmetrically arranged resembling a pair of large ears of a rabbit head.
