In view of this, according to a first aspect of embodiments of the present invention, a cover assembly is provided. The cover body assembly comprises a cover body, a disturbance assembly and a flow guide piece. The cap body has first and second sides facing away from each other. The disturbance component is connected with the cover body, at least part of the disturbance component is located on the first side of the cover body, and the disturbance component can disturb airflow on the first side of the cover body. The flow guide member is distributed on the surface of the first side of the cover body.

The embodiment of the utility model provides a lid subassembly, including the lid body and the disturbance subassembly that can disturb the first side air current of lid body, on the one hand, the air current that the disturbance subassembly disturbance produced can form the air curtain in the first side of lid body, produces the barrier action, can reduce the steam that comes from the first side and the possibility of lid body contact, and steam probably is 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 before the disturbance subassembly starts, the first side surface of lid body has existed a certain amount of liquid, and the air current that the disturbance subassembly disturbance produced also can drive these liquid and remove, through set up the water conservancy diversion spare at the first side surface of lid body, the water conservancy diversion spare can cooperate with the air current that the disturbance produced, and the air current drives liquid and flows to all around along the water conservancy diversion spare, can reduce the liquid accumulation on the first side surface of lid body equally. In addition, the pressure difference formed by the disturbance assembly can also discharge redundant water vapor, and different cooking effects can be formed by controlling the rotating speed.

With the progress of cooking, steam can be produced gradually in the cooking chamber 800, and after meeting the lower lid body 200 of temperature, these steam can become the comdenstion water by condensation on its surface, and the food that the condensation water drips in the cooking chamber 800, for example rice surface can make the relevant position of food different with the colour of other positions, causes the food colour of cooking the completion inhomogeneous, produces the white phenomenon of dripping. The air curtain formed by the disturbance component 300 disturbing the air flow can fundamentally solve the problem of the condensed water of the cover body 200, and for the existing liquid, such as soup attached to the cover body 200 in the early cooking stage, and a small amount of condensed water condensed from the water vapor passing through the air curtain, the liquid can be blown to the peripheral wall surface of the cooking cavity 800, such as the sidewall of the pot body 700 of the cooking appliance 1, by the cooperation of the air flow and the flow guide member 400, so that the liquid can flow down along the pot body 700 and reach the periphery of the food. On one hand, the problem of dripping caused by the fact that condensed water drops on the surface of the food can be solved, and the color of the surface of the food is uniform. On the other hand, the pot body 700 often is the metal material, and heat-conduction leads to the temperature on the high side, and usable comdenstion water reduces the food all around with the difference in temperature at middle part for the lateral wall of the pot body 700 to avoid pot limit outward appearance difference, and can promote the temperature homogeneity of food, help promoting the culinary art effect. 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.

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. 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.

As shown in FIG. 2, 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. 2, 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. 2, 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. 1, 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. 2, 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.

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.

Moreover, the fan blade 323 is directly connected with the surface of the connecting disc 322 on the side away from the shell 311, so that the connecting area is large, the fan blade 323 is stably connected with the connecting disc 322, and under the condition that the rotating speeds are the same, the fan blade 323 arranged on the surface of the connecting disc 322 on the side away from the shell 311 is more stable, so that the structural strength of the disturbing piece 321 is improved. For example, the fan blades 323 may be arranged to extend circumferentially and uniformly outward along the radial direction of the rotating shaft 325, and at this time, the fan blades 323 rotate to drive the airflow to rotate, so as to realize rapid rotation of the airflow.

In some embodiments, the perturbation assembly 300 comprises a blower coupled to the cover body 200, the axis of rotation of the blower extending away from the cover body 200.

The rotation shaft of the blower is extended toward a direction away from the cover body 200, that is, along the height direction of the cooking chamber 800, so that the blower is rotated in the horizontal direction, and thus the airflow and the fluid can be guided to rotate in the horizontal direction, and the fluid in the cooking chamber 800 can be more easily driven to flow.

It can be understood that, directly adopt off-the-shelf fan in disturbance subassembly 300, the fan drives vapor high-speed rotatory in culinary art chamber 800, under strong centrifugal force, liquid in the culinary art chamber 800 is rotatory along with high-speed rotatory air current together, and bottom heating device is continuous heating, make liquid not only roll from top to bottom in the culinary art chamber 800, and be rotary motion along the rotatory direction of disturbance subassembly 300, thereby make the liquid disturbance in the culinary art chamber 800 strengthen greatly, make the edible material be heated more evenly in the culinary art process.

In some embodiments, the fan is a centrifugal fan or a diagonal flow fan.

In this embodiment, the fan may be a centrifugal fan or an oblique flow fan, so that the fluid is driven to rotate by the airflow in the cooking cavity 800. When the centrifugal fan is adopted, the noise of the centrifugal fan is low, the airflow rotating speed is high, and the high-speed rotation of the fluid is favorably driven. When the oblique flow fan is adopted, the oblique flow fan is small in size, large in air volume and more violent in fluid disturbance, and is beneficial to driving a large amount of fluid to move.

In summary, the cooking apparatus in the related art usually includes a low power heating section or a heat preservation section in the later cooking stage, and the cooking apparatus does not continue to heat in these stages, so that it is difficult to maintain the temperature of the gas above the food material, and the temperature of the lid body also decreases. The existing solution is to arrange a complex concave-convex structure on the cover plate or to perform surface treatment, or to add a resistance wire to maintain the temperature, but the effect is poor because the water vapor cannot be prevented from rising. The embodiment of the utility model provides a lid subassembly 100, low heating power or heat preservation stage after the culinary art process is accomplished, detachable disturbance subassembly 300 rotates, forms the air curtain near lid body 200 first side surface, forms pressure air curtain district, and vapor and lid body 200 keep apart completely, make the unable contact lid body 200 of vapor that evaporates and then the condensation be liquid to thoroughly solve the problem of comdenstion water. As the disturbance assembly 300 operates and the liquid evaporates, the pressure in the cooking chamber 800 increases and water vapor is directly exhausted through the exhaust hole 540. On the other hand, a small amount of existing condensed water on the cover body 200 is extruded all around and flows down along the side surface of the pot body 700 with higher temperature, so that the temperature of the food material at the center is greatly reduced, the phenomenon of uneven color is reduced, and the user experience is greatly improved. In addition, through the rotational speed of control disturbance subassembly 300, steerable exhaust speed, with the culinary art function cooperation, can realize different culinary art effects.
