A cooking appliance of some embodiments of the present application will be described below with reference to fig. 1 to 25.

As shown in fig. 2, 3, 4, 5, 6, 20, 21, 22 and 23, a first aspect of the present invention provides a cooking appliance including: a pot assembly 10, the pot assembly 10 including a container body 110 having a cooking cavity 111; the air duct 20 is arranged around the container body 110, the air duct 20 has a first air outlet 240 and a second air outlet 250 which are circumferentially distributed, the first air outlet 240 and the second air outlet 250 face the side wall direction of the container body 110, and the first air outlet 240 is located below the second air outlet 250; the side wall of the container body 110 is provided with a first container air inlet 1101 and a second container air inlet 1102 which are circumferentially distributed, the first air outlet 240 is arranged opposite to the first container air inlet 1101, and the second air outlet 250 is arranged opposite to the second container air inlet 1102; and a hot air assembly including an air supply member 310 and a heating member 320, the hot air assembly being disposed in the air duct 20, the air supply member 310 being capable of blowing air heated by the heating member 320 in the air duct 20 into the cooking chamber 111.

The cooking appliance provided by the embodiment of the present invention includes a pot assembly 10, an air duct 20 and a hot air assembly, the pot assembly 10 may be used for containing food materials and the like, the hot air assembly blows hot air out of a first air outlet 240 and a second air outlet 250 which are located at an inner ring of the air duct 20, the first air outlet 240 and the second air outlet 250 are both distributed circumferentially, and the first air outlet 240 and the second air outlet 250 respectively correspond to a first container air inlet 1101 and a second container air inlet 1102 which are arranged on a side wall of a container body 110, so that air can be fed along the circumferential direction of the container body 110, the air flow can be blown away toward the inner center of the container body 110 due to the circumferential air feeding, and the air flow is distributed uniformly in the container body 110; and first air outlet 240 is located the below of second air outlet 250, promptly, first air outlet 240 and second air outlet 250 form two air outlets that distribute one on top of the other, can make the flow of hot-air in container body 110, distribute more evenly for eat material and be heated evenly, the maturity is unanimous, it is effectual to cook, and can realize the multiaspect heating of eating the material, and then promote heating efficiency, shorten and cook for a long time.

In some embodiments, optionally, the first air outlet 240 and/or the second air outlet 250 may be circumferentially and continuously distributed openings, and at this time, the first air outlet 240 and/or the second air outlet 250 is an annular air outlet; the openings can be circumferentially distributed at intervals, and the number of the openings is multiple; likewise, the first container intake vent 1101 and/or the second container intake vent 1102 may be circumferentially continuously distributed openings, in which case the first container intake vent 1101 and/or the second container intake vent 1102 are annular intake vents; the first container intake vent 1101 and/or the second container intake vent 1102 may also be circumferentially spaced openings, and the number of openings may be multiple.

With respect to the specific structure of the cookware assembly 10, in some embodiments, as shown in fig. 2, 3, 4, and 20, the cookware assembly 10 further includes: a frying plate 140, the frying plate 140 being detachably disposed in the cooking chamber 111, the frying plate 140 being located above the first container intake vent 1101 and below the second container intake vent 1102.

In these embodiments, by providing the first container air inlet 1101 and the second container air inlet 1102 on the container body 110, the hot air can heat the food material placed on the frying plate 140 from the upper and lower surfaces simultaneously, so that the upper and lower surfaces of the food material are heated simultaneously, and thus the food material is heated more uniformly, the ripeness is consistent, and the cooking effect is good; since neither the first container air inlet 1101 nor the second container air inlet 1102 is directly opposite to the frying plate 140, hot air can be prevented from directly blowing to the food material placed on the frying plate 140 to cause scorching, and the cooking effect can be further improved.

Specifically, as an example, the frying plate 140 is provided with a plurality of oil leakage holes, which can filter grease and prevent grease from accumulating at the bottom of the food material, and the food material is too greasy.

Further, in order to enable the hot wind blown out from the second outlet 250 located above to be blown onto the food material, in some embodiments, as shown in fig. 4 and 12, the second outlet 250 is inclined downward, and the inclination angle α 8 of the second outlet 250 is 30 ° to 60 °.

In these embodiments, the provision of the second outlet 250 in an inclined configuration can serve to direct the airflow within the air cavity 260, such that the circularly rotating airflow in the air cavity 260 can be directed obliquely downward into the container body 110, such that the airflow can flow to the food material located on the fry vat 140 of the container body 110. Further, the inclination angle α 8 of the second air outlet 250 is defined within a range of 30 ° to 60 °, in which the hot air blown into the container body 110 via the first air outlet 240 can be made to reach the center of the food material distribution position, and the resistance of the hot air entering from the first container air inlet 1101 rising upward is overcome, so that the inside of the container body 110 is heated uniformly; specifically, if the inclination angle is too small, the wind may reach the surface of the food material in advance, may not reach the central range of the food material in the container body 110, may form a rotation inside the container body 110, and then may be thrown toward the sidewall of the container body 110, causing uneven heating, resulting in a central temperature lower than the outer periphery; if the inclination angle is too large, the wind can delay to reach the central range of the food material, and can exceed the central range of the food material in the container body 110, and then rotate in the container body 110, and further throw the food material to the side wall of the container body 110, so that uneven heating is caused, and the central temperature is lower than the periphery.

For the specific arrangement of the first outlet port 240 and the second outlet port 250, in some embodiments, as shown in fig. 12, the distance H3 between the first outlet port 240 and the second outlet port 250 in the vertical direction is 40mm to 80 mm. Within this range, the distance H3 between the first outlet 240 and the second outlet 250 is ensured to be appropriate, so that the problem that the food is too close to the first outlet and the second outlet is burnt and the like due to too close distance is avoided, and the problem that the cooking time is long and the food is difficult to cook due to too far heating efficiency is also avoided.

In some embodiments, as shown in fig. 12, the length W1 of the first air outlet 240 in the vertical direction is less than the length W2 of the second air outlet 250 in the vertical direction. Since the hot air rises upward, the second outlet 250 needs to be blown obliquely downward, the pressure required is greater, and thus the length W2 of the second outlet 250 in the vertical direction is set to be greater.

As shown in fig. 12, in some embodiments, the length W1 of the first air outlet 240 in the vertical direction is 1.5mm to 5 mm. In this range, the air output can be ensured, and the air speed through the first air outlet 240 is increased, so that the air flow can be distributed to most of the space in the container body 110, and the heating efficiency is ensured; specifically, if the length W1 of the first air outlet 240 in the vertical direction is too large, the flow rate of the wind is increased, the wind speed is reduced, and the hot wind cannot be blown to the surface of the food material; if the height is too small, the flow rate is reduced, the wind speed is increased, and the heating efficiency is low.

In some embodiments, the first container intake vent 1101 is 2mm to 7mm in length in the vertical direction. Within this range, the size of the first outlet port 240 can be better matched and slightly larger than the first outlet port 240, thereby reducing the leakage of the hot wind as much as possible.
