Specifically, the lid body has first and second sides facing away from each other, the cooking cavity being located on the first side of the lid body. Along with the culinary art goes on, can produce steam gradually in the culinary art intracavity, these steam meet behind the lower lid body of temperature, can become the comdenstion water on its surface condensation, influence visual effect. Through the disturbance subassembly that sets up the first side air current that can disturb the lid body, can produce three-dimensional rotatory air current disturbance in the culinary art intracavity, reduce liquid and gather, help optimizing visual effect, guarantee that the visual degree of product is high. On the one hand, the air current that the disturbance subassembly disturbance produced can form the air curtain at the first side of lid body, produces the barrier effect, can reduce the possibility that the vapor that comes from the first side contacts with the lid body, and the vapor probably becomes the comdenstion water on the lid body surface behind the contact lid body, therefore the air curtain can reduce the comdenstion water formation on lid body surface, fundamentally solves the comdenstion water problem of lid body. On the other hand, even if a certain amount of liquid exists on the first side surface of the cover body before the disturbance assembly is started, for example, liquid such as soup attached to the cover body in the early cooking stage, or a small amount of condensed water condensed from water vapor passing through the air curtain exists, the air flow generated by the disturbance of the disturbance assembly can drive the liquid to move, and the liquid accumulation on the first side surface of the cover body can be reduced. In other words, when the disturbance assembly is in the process of stirring in the cooking cavity, the liquid on the window can be thrown to the edge of the window along with the internal rotating airflow, so that the real visual effect in the cooking process is realized. At the moment, the cover body assembly does not need to be provided with a movable heat-insulating cover in the related technology, so that the product structure is simplified, the development of a mould is reduced, and the production cost is reduced.

With the progress of cooking, steam can be gradually generated in the cooking cavity 800, and after the steam meets the cover body 200 with a lower temperature, the steam can be condensed into condensed water on the surface of the cover body, so that the visual effect is influenced. Through the disturbance subassembly 300 that sets up the first side air current that can disturb lid body 200, can produce three-dimensional rotatory air current disturbance in culinary art chamber 800, reduce liquid and gather, help optimizing visual effect, guarantee that the visual degree of product is high. On one hand, the air flow generated by the disturbance of the disturbance assembly 300 can form an air curtain on the first side of the cap body 200 to generate a barrier effect, so that the possibility that the water vapor from the first side contacts the cap body 200 can be reduced, and the water vapor can be surfaced into condensed water on the surface of the cap body 200 after contacting the cap body 200, therefore, the air curtain can reduce the formation of the condensed water on the surface of the cap body 200, and the problem of the condensed water of the cap body 200 is fundamentally solved. On the other hand, even if a certain amount of liquid, such as soup or the like, attached to the lid body 200 during the early cooking stage or a small amount of condensed water condensed from the water vapor passing through the air curtain exists on the first side surface of the lid body 200 before the disturbing assembly 300 is activated, the air flow generated by the disturbance of the disturbing assembly 300 can drive the liquid to move, and the accumulation of the liquid on the first side surface of the lid body 200 can be reduced. In other words, during the stirring process of the disturbance assembly 300 inside the cooking cavity 800, the liquid on the window is thrown to the edge of the window along with the internal rotating airflow, thereby realizing the real visual effect during the cooking process. At this time, the cover assembly 100 does not need to be provided with a movable heat-insulating cover in the related art, which helps to simplify the product structure, and helps to reduce the development of molds and production cost.

Meanwhile, the liquid on the surface of the cover body 200 drips on the food in the cooking cavity 800, such as the surface of rice, so that the color of the corresponding position of the food is different from the color of other positions, the color of the cooked food is not uniform, and the dripping white phenomenon is generated, so that the reduction of the liquid accumulation of the cover body 200 also helps to reduce the dripping white phenomenon. In addition, the air current that disturbance subassembly 300 drove blows the liquid on lid body 200 surface to the wall all around of culinary art chamber 800, for example the pot body 700 lateral wall of cooking utensil 1, can make liquid flow down in the same direction as pot body 700, and pot body 700 often is the metal material, and heat-conduction leads to the temperature on the high side, and usable comdenstion water is the cooling of pot body 700 lateral wall, reduces food all around with the difference in temperature at middle part, thereby avoids pot limit outward appearance difference, and can promote the temperature homogeneity of food, help promoting the culinary art effect.

In addition, through the air current in disturbance subassembly 300 disturbance culinary art chamber 800, when disturbance intensity is enough, the air current of disturbance can also stir the liquid of culinary art chamber 800, and then realizes eating the material thermally equivalent in the culinary art chamber 800, reduces piling up of bubble simultaneously, makes cooking utensil 1 can adopt high-power continuous heating, promotes the food taste.

It can be understood that, in the cooking heating stage, the cooking chamber 800 and the food in the cooking chamber 800 are heated, so that the temperature of the food in the cooking chamber 800 is rapidly raised. Because cooking utensil 1 generally heats through bottom heating device 910, and the culinary art chamber 800 inner space is limited, and culinary art chamber 800 receives bottom heating device 910 heating, and disturbance subassembly 300 drives the air current in the culinary art chamber 800, and the gas flow in the culinary art chamber 800 is accelerated, strengthens the vortex, is heated more evenly. At the boiling culinary art stage, the bubble that the boiling produced drives culinary art liquid and rolls from top to bottom, disturbance subassembly 300 drives the air current in culinary art chamber 800, culinary art liquid flows along with the air current that disturbance subassembly 300 drove, make culinary art liquid in the culinary art chamber 800 not only realize rolling from top to bottom along with the heating boiling, still realize flowing along with the air current through disturbance subassembly 300, make the more violent convection heat transfer of culinary art liquid in the culinary art chamber 800, further improve the heat transfer of the bottom of cooking utensil 1, it is more even to make the culinary art eat the material and be heated at the culinary art in-process. Specifically, the disturbance assembly 300 drives the steam to rotate at a high speed in the cooking cavity 800, and under the action of strong centrifugal force, the liquid in the cooking cavity 800 rotates along with the airflow rotating at a high speed, and the bottom heating device 910 continuously heats the liquid, so that the liquid in the cooking cavity 800 not only rolls up and down, but also rotates along the rotating direction of the disturbance assembly 300, and thus the disturbance of the liquid in the cooking cavity 800 is greatly enhanced, and the food material is heated more uniformly in the cooking process. In addition, the bubbles in the cooking utensil 1 overflow in a large amount due to long-time high-power heating, and the internal flow field and the pressure change rapidly due to the disturbance assembly 300, so that the bubbles cannot be stacked for a long time, and the phenomenon of no bubble overflow under the high-power long-time heating condition is achieved. At this moment, heating power does not need to be sacrificed, the cooking appliance 1 can continuously heat for a long time under the condition of high power or power ratio adjustment, long-time high-temperature cooking of food materials is realized, cooking time is shortened, and food taste is improved. That is to say, disturbance subassembly 300 has not only realized making the culinary art edible material be heated evenly at the culinary art in-process, has also solved cooking utensil 1 in the problem that the culinary art in-process bubble spills over in a large number moreover, can realize high-power heating, promotes food taste.

In addition, other functions may be performed by the disturbance assembly 300 during other stages of cooking. Taking cooked rice as an example, when the cooked food materials are in the water absorption cooking stage, the rice grains give off stale flavors in the water absorption cooking process, the disturbance assembly 300 drives the air flow in the cooking cavity 800 to quickly discharge the stale flavors given off by the rice, so that the rapid aging removal is realized, and the flavor of the subsequent rice is not influenced. In the heat preservation stage, the culinary art has been accomplished, and disturbance subassembly 300 will cook the quick discharge of steam in the chamber 800, can directly open and cover body 200, prevent to appear scalding danger, need not wait for the cooling process after food is cooked yet, realize uncapping instant.

Specifically, the perturbation assembly 300 may be directly connected with the cap body 200, or may be indirectly connected with the cap body 200 via other connection structures.

In some embodiments, the surface of the first side of the cap body 200 has hydrophilicity or hydrophobicity.

In this embodiment, the first side surface of the cap body 200 may be treated with a hydrophilic surface or a hydrophobic surface to make it hydrophilic or hydrophobic, so that the visual effect of the cap body assembly 100 is improved by combining with the effect of the disturbance assembly 300. Particularly, as for the first side surface having hydrophilicity, the water vapor generated in the cooking cavity 800 is condensed into a thin layer of water mist after encountering the first side surface having hydrophilicity and lower temperature, and the visual degree of the window is not reduced, so that the visual effect can be ensured, and the white dripping phenomenon in the cooking process can be effectively reduced. Along with the increase of the vapor that produces in the culinary art chamber 800, the water smoke of first side surface can the bodiness, influences visual effect, and disturbance subassembly 300 then usable air current with the water smoke to promoting all around, play the effect of attenuate water smoke, help optimizing visual effect. For the case that the first side surface has hydrophobicity, the water vapor generated in the cooking cavity 800 can be condensed into droplets with sufficient size after encountering the first side surface with lower temperature and hydrophobicity, and can rapidly flow around under the blowing of the disturbance assembly 300 without staying on the first side surface, thereby improving the visualization effect of the cover assembly 100 and reducing the white dripping phenomenon in the cooking process.

Polysulfone has good rigidity and toughness, is resistant to temperature and thermal oxidation, is suitable for cooking environment, is nontoxic, is beneficial to ensuring food safety, is easy to mold and process, and is convenient for manufacturing products.

As shown in FIG. 5, in some embodiments, the perturbation assembly 300 is located in a central region of the first cover 210.

In this embodiment, particularly, the disturbance assembly 300 is disposed in the central region of the first cover 210, when the disturbance assembly 300 rotates, a stable air curtain can be uniformly formed in the upper space of the cooking cavity 800, a reliable barrier can be formed, which helps to reduce the possibility of the water vapor contacting the cover body 200, and the liquid on the surface of the first cover 210 can be uniformly carried around by the air flow, so that the liquid accumulation on the surface of the first cover 210 is sufficiently reduced, which helps to improve the visualization effect.

In some embodiments, the distance between the two points farthest apart on the first cover 210 is denoted as a first distance, the distance between the two points farthest apart on the perturbing member 300 is denoted as a second distance, and the ratio of the second distance to the first distance is greater than or equal to 0.15 and less than or equal to 0.5.

In this embodiment, the first distance may reflect the size of the first cover 210, and when the first cover 210 is circular, the first distance is the outer diameter of the first cover 210, and the second distance may reflect the size of the perturbation assembly 300, and when the perturbation assembly 300 includes a fan, the second distance is the outer diameter of the fan blade. By defining a range of values for the ratio of the second distance to the first distance, the relative size relationship of the perturbation assembly 300 and the first cover 210 may be defined. The upper limit value can ensure that the disturbance component 300 is small enough, avoid blocking the sight of a user, and help to ensure the visualization effect. The lower limit value enables the disturbance component 300 to generate enough disturbance to the airflow without adopting an overlarge rotating speed, so that the visual effect is ensured, the operation noise of the disturbance component 300 is favorably and reasonably controlled, and the comprehensive performance of the product is improved. Further, the ratio may range from 0.2 to 0.4, for example, may be 0.25, and may be 0.3, for example.

As shown in fig. 5, in some embodiments, the cap body 200 further comprises: a second cover 220, the second cover 220 being disposed to overlap the first cover 210, the second cover 220 forming a window, and a vacuum interlayer 230 being formed between the second cover 220 and the first cover 210.

In this embodiment, the cover body 200 specifically includes the first cover 210 and the second cover 220 stacked, and by disposing the first cover 210 and the second cover 220 stacked and forming the vacuum interlayer 230 therebetween, the heat transfer from the first side to the second side of the cover body 200 can be reduced, and the excellent heat insulation performance is ensured, so as to play a role in heat preservation, and the temperature difference between the cover body 200 and the cooking cavity 800 can be reduced, so that the water vapor is not easily changed into condensed water after contacting the first cover 210, and the condensed water problem of the cover body 200 can be fundamentally solved. It is understood that when the cap body 200 includes the aforementioned outer cap 240 and inner cap 250, the second cap 220 is also inserted into the aforementioned through hole.

In some embodiments, the surface of the first side of the cap body 200 comprises an inertial flow guiding region that gradually slopes toward the first side of the cap body 200 as the radial spacing of the cap body 200 from the perturbation assembly 300 increases.

At least part of the area of the first side surface of the cover body 200 is marked as an inertial flow guiding area, and the inertial flow guiding area forms an inclined plane, specifically, the inclined plane is inclined downwards as the distance from the disturbance assembly 300 increases, so that the liquid distributed in the inertial flow guiding area flows downwards under the action of gravity and inertia and in the direction away from the disturbance assembly 300, and the direction of the liquid flowing is consistent with the direction of the air flow guiding liquid, so that the effect of enhancing flow guiding can be achieved by means of inertia, and the flow guiding effect is improved. Specifically, the inertial diversion area is at least a portion of the first side surface of the cap body 200, and may be a partial area close to the disturbing assembly 300, and since this portion of the liquid tends to be in a static state or has a smaller initial flow velocity, the diversion requirement is greater, and the diversion effect may be improved by means of inertia, and of course, the inertial diversion area may also be a partial area far from the disturbing assembly 300 to guide the liquid to flow around rapidly. In addition, the inertial diversion area may be a planar area or a curved area, and may protrude toward the first side of the cap body 200 or may be recessed in a direction away from the first side of the cap body 200. The thickness of the cap body 200 can be made to be substantially consistent everywhere, that is, the surface of the second side of the cap body 200 is also a corresponding inclined surface, and the surface of the second side of the cap body 200 can also be made to be an approximate horizontal plane, and only the surface of the first side of the cap body 200 is made to be at least partially inclined, so that the thickness of the cap body 200 is increased along with the increase of the radial distance from the disturbing component 300, which is an implementation manner of the present invention.

As shown in fig. 7, in some embodiments, the cover assembly 100 further comprises: the exhaust hole 540, the exhaust hole 540 penetrates the cap body 200 in the thickness direction of the cap body.

In this embodiment, the lid assembly 100 further includes a vent hole 540 penetrating the lid body 200, so that water vapor generated during cooking can be smoothly discharged out of the cooking chamber 800 to meet cooking requirements. In addition, some of the water vapor can be discharged through the vent hole 540 by the disturbing assembly 300, which helps to reduce the amount of condensed water generated on the cap body 200.

As shown in fig. 8, in some embodiments, vent 540 avoids perturbation assembly 300.

In this embodiment, the vent hole 540 is disposed at a position avoiding the disturbing assembly 300, so that the disturbing assembly 300 can be reliably connected to the cap body 200, and the reliability of the product is improved. In addition, the vent 540 is used for water vapor generated in the cooking process to pass through, and the water vapor is higher in temperature, so that the damage of the high-temperature water vapor to the disturbance assembly 300 can be reduced, and the service life of the disturbance assembly 300 can be prolonged.

As shown in FIG. 5, in some embodiments, the vent 540 is disposed near the outer edge of the perturbation assembly 300.

In this embodiment, since the wind speed is high at the outer edge of the turbulence assembly 300, by disposing the air discharge hole 540 at this position, the water vapor can be accelerated to be discharged to the outside, which helps to ensure that the cooking appliance 1 is quickly and smoothly vented.

In some embodiments, as shown in FIG. 8, vent 540 is configured as an arcuate hole, with the centerline of vent 540 projecting away from the central axis of perturbation assembly 300.

In this embodiment, vent 540 is specifically configured as an arcuate hole that projects away from the central axis of perturbing member 300, i.e. with reference to the central axis of perturbing member 300, and can extend approximately circumferentially. On one hand, the structure can increase the exhaust circulation area, is beneficial to increasing the exhaust amount and improving the exhaust speed. On the other hand, the shape of the air discharge hole 540 is adapted to the swirling air flow disturbed by the disturbing assembly 300, and also helps to promote smooth air discharge.

Specifically, the cover assembly 100 further includes a mounting hole 510 as shown in fig. 7, and the mounting hole 510 penetrates the cover body 200 in the thickness direction of the cover body 200. As shown in fig. 7, when the cap body 200 includes the first cap 210, the mounting hole 510 penetrates the first cap 210. When the cap body 200 includes the first cap 210 and the second cap 220, the mounting hole 510 may penetrate both the first cap 210 and the second cap 220.

In some embodiments, as shown in fig. 1 and 2, the cover assembly 100 further includes an exhaust member 520, the exhaust member 520 is adapted to fit the mounting hole 510, as shown in fig. 3, 4 and 5, the exhaust member 520 is connected to the disturbing assembly 300, that is, the disturbing assembly 300 is indirectly connected to the cover body 200 via the exhaust member 520, and the exhaust hole 540 penetrates through the exhaust member 520 along the thickness direction of the exhaust member 520.

In other embodiments, as shown in FIGS. 7 and 8, perturbation assembly 300 is fitted into mounting hole 510 and vent holes 540 are positioned in an area that is offset from mounting hole 510. As shown in fig. 7, when the cap body 200 includes the first cap 210, the venting hole 540 penetrates the first cap 210. When the cap body 200 includes the first cap 210 and the second cap 220, the vent hole 540 simultaneously penetrates through the first cap 210 and the second cap 220, as shown in fig. 12, in this case, the cap body assembly 100 further includes a vent member 520, the vent member 520 is adapted to the vent hole 540, the vent member 520 includes a vent channel 530, and the arrangement of the vent member 520 ensures the sealing performance of the vacuum interlayer 230 between the first cap 210 and the second cap 220. It is understood that, when the cap body 200 only includes the first cap 210, i.e., the vacuum interlayer 230 is not included, the cap body assembly 100 may include the exhaust member 520 or may not include the exhaust member 520.

As shown in fig. 10, in some embodiments, the cover assembly 100 further comprises: and a flow guide member 400, the flow guide member 400 being distributed on a surface of the first side of the cap body 200.

In this embodiment, by providing the flow guide member 400 on the first side surface of the cap body 200, the flow guide member 400 can cooperate with the air flow generated by the disturbance, and the air flow drives the liquid to flow around along the flow guide member 400, which can also reduce the liquid accumulation on the first side surface of the cap body 200.

When the cover assembly 100 includes the exhaust hole 540, as shown in fig. 7, the exhaust hole 540 avoids the guide member 400. The guide member 400 is used for guiding the liquid on the surface of the cap body 200 to flow around along the guide member 400, and the vent holes 540 are arranged to avoid the guide member 400, so that the structural integrity of the guide member 400 can be ensured, the liquid can be guided reliably, and the liquid accumulation can be reduced. In addition, the design can prevent the liquid from being discharged out of the cooking cavity 800 through the exhaust hole 540, so that the cooking appliance 1 sputters high-temperature liquid, and the use safety of the product is guaranteed.

When the cap body 200 includes the first cap 210, the fluid guides 400 are distributed on the surface of the first cap 210, that is, the second cap 220 and the first cap 210 are respectively located on the second side and the first side, and liquid may adhere to the surface of the first cap 210 facing away from the second cap 220, so that by providing the fluid guides 400, the accumulation of liquid in the first cap 210 can be reduced, and the accumulation of liquid in the cap body 200 can also be reduced. Specifically, the baffle 400 may extend to the outer edge of the first cover 210, and the liquid on the surface of the first cover 210 may be guided to flow along the baffle 400 to the outer edge of the first cover 210, which helps to substantially reduce the accumulation of the liquid on the surface of the first cover 210.

As shown in FIG. 8, in some embodiments, the baffle 400 extends away from the disturbance assembly 300 from an area corresponding to the disturbance assembly 300.

In this embodiment, since the liquid formed near the disturbing component 300 tends to be in a static state or has a smaller initial flow velocity, by disposing the flow guiding element 400 at the region of the cover body 200 corresponding to the disturbing component 300, specifically, the region corresponding to the outer edge of the disturbing component 300, the liquid with a static middle or a small initial flow velocity can be guided to flow along the flow guiding element 400 under the action of the airflow, so as to perform the necessary flow guiding function. In addition, by extending the diversion member 400 away from the disturbance assembly 300, the liquid can be guided to flow around in cooperation with the flow of the air flow, thereby substantially reducing the liquid accumulated on the surface of the cover body 200.

As shown in FIG. 8, in some embodiments, the baffle 400 deflects in a clockwise or counterclockwise direction, centered on the central axis of the disturbance assembly 300.

In this embodiment, the disturbing assembly 300 can rotate the surrounding air by its rotation to form a rotating airflow. The diversion member 400 is disposed to deflect relative to the central axis of the disturbance assembly 300, and can cooperate with the rotating airflow, so that the liquid on the surface of the cover body 200 moves along the movement direction of the airflow, which helps to reduce the obstruction to the liquid, and the liquid flows around more smoothly. Wherein, the guiding member 400 can deflect along the clockwise direction, also can deflect along the anticlockwise direction to adapt to different disturbance assemblies 300, when the quantity of guiding member 400 is a plurality of, as long as guarantee that the deflection direction of all guiding members 400 is unanimous.

As shown in FIG. 8, the outer curved arrow indicates the direction of rotation of the perturbing member 300, and in some embodiments the direction of deflection of the baffle 400 coincides with the direction of rotation of the perturbing member 300.

In this embodiment, by deflecting the diversion member 400 according to the rotation direction of the disturbance assembly 300, the diversion direction can be ensured to be adapted to the rotation direction of the airflow, and the obstruction to the liquid flow can be sufficiently reduced.

As shown in fig. 7, in some embodiments, the number of flow guides 400 is at least two, all of the flow guides 400 are spaced around the perturbation assembly 300, and a flow guide channel 410 is formed between two adjacent flow guides 400.

In this embodiment, the flow guiding members 400 are specifically defined as a plurality of flow guiding channels 410 distributed at intervals around the disturbing assembly 300, and radial flow guiding channels 410 can be formed, so as to guide the liquid to flow radially along the flow guiding channels 410, and the flow guiding channels can adapt to the rotating airflow direction disturbed by the disturbing assembly 300, thereby sufficiently improving the flow guiding effect and reducing the liquid accumulation of the cover body 200.

As shown in fig. 8, in some embodiments, the cylindrical surface coaxial with the disturbance assembly 300 is used as a reference surface, the extending length in the circumferential direction of the reference surface is used as a width, the flow guide 400 has a first end close to the disturbance assembly 300 and a second end far away from the disturbance assembly 300, and the width of the flow guide 400 at the first end is smaller than that of the flow guide 400 at the second end.

In this embodiment, as the radial distance from the disturbing assembly 300 increases, the circumferential length of the cover body 200 gradually increases, and the width of the flow guide member 400 increases, so that the width of the flow guide channel 410 can be appropriately shortened, thereby preventing the flow guide channel 410 from losing the flow guide effect due to the rapid increase of the width, and thus the flow guide channel 410 is reasonably matched with the air flow, and the flow guide effect is improved. Specifically, the width ratio of the flow guide channel 410 and the flow guide member 400 may be adjusted according to the specific amount of the liquid, so that the width of the flow guide channel 410 has a slowly increasing trend to match the airflow, for example, at the same radial length, so that the width of the flow guide channel 410 is equal to the width of the flow guide rib.

In some embodiments, the thickness of the flow guide 400 at the first end is greater than the thickness of the flow guide 400 at the second end.

In this embodiment, the liquid near the disturbance assembly 300 tends to be at a standstill or has a low initial flow velocity, and thus has a high diversion demand, and the liquid is driven by the airflow to have a high velocity far from the disturbance assembly 300, and thus the diversion demand is reduced. Set up to first end thickness, second end thin through with water conservancy diversion piece 400, specifically can attenuate gradually from first end to second end, can reduce the material under the condition that satisfies the water conservancy diversion demand, help reducing product cost, promote product competitiveness.

As shown in fig. 10 and 12, in some embodiments, the cover assembly 100 further comprises: and a sealing member 600, wherein the sealing member 600 is connected with the cover body 200, and the sealing member 600 can contact with the pot body 700 of the cooking appliance 1.

In this embodiment, the cover assembly 100 further includes a sealing member 600 connected to the cover body 200, and the liquid on the surface of the cover body 200 can flow around and to the sealing member 600 under the action of the disturbance assembly 300. Since the sealing member 600 can contact with the pot body 700, particularly when the cooking utensil 1 is closed, the liquid can be guided to flow along the sealing member 600 to the peripheral wall surface of the cooking cavity 800, such as the side wall of the pot body 700 of the cooking utensil 1, and a reliable flow guiding effect is achieved. Specifically, the seal 600 is a seal ring.

In some embodiments, as shown in fig. 5, further, the perturbation component 300 comprises: a base assembly 310 and a rotation assembly 320, the base assembly 310 being connected to the cover body 200; the rotating assembly 320 is detachably connected to the base assembly 310, and the rotating assembly 320 is at least partially located at the first side of the cover body 200.

In this embodiment, the disturbance assembly 300 includes a base assembly 310 capable of being coupled to the cover body 200 and a rotation assembly 320 capable of inducing the flow of the air in the cooking chamber 800, the base assembly 310 is coupled to the cover body 200, and the rotation assembly 320 is detachably coupled to the base assembly 310. When setting up disturbance subassembly 300 on cooking utensil 1's the lid body 200, in the culinary art process, realize the air current in disturbance subassembly 300 disturbance culinary art chamber 800, help accelerating the air current and flow, make the edible material in the culinary art chamber 800 be heated more evenly, promote the taste of culinary art back food. When the cooking appliance 1 needs to cook food materials with high starch content such as rice, porridge and the like, the rotating assembly 320 is mounted on the base assembly 310, the rotating assembly 320 disturbs airflow in the cooking cavity 800, and at least the food materials are heated more uniformly and prevented from overflowing in a large amount. When the starch content of the food material is low or the cooking requirement is low, the rotating assembly 320 is detached, so that the use of the cooking appliance 1 is not affected.

After the cooking appliance 1 finishes cooking, the rotating assembly 320 can be cleaned independently by detaching the rotating assembly 320 from the base assembly 310, so that food safety is guaranteed. When the rotating assembly 320 contacts water vapor and air bubbles in the process of disturbing the airflow and the rotating assembly 320 is contaminated with a small amount of food materials or water vapor, the rotating assembly 320 is detached from the base assembly 310, i.e., the rotating assembly 320 is separated from the base assembly 310, so that the rotating assembly 320 can be cleaned independently, the rotating assembly 320 is kept clean, and the food safety is ensured.

The rotating assembly 320 is at least partially located at the first side of the cap body 200 to further ensure stability of the rotating assembly 320 during rotation.
