The fan assembly rotates under the push of the airflow and breaks the bubbles. However, since the food bubbles will generate resistance to the rotation of the blades, it will make it difficult to start the fan assembly. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the utility model provides a cover assembly.

[0005] A second aspect of the present invention provides a cooking utensil.

[0006] In view of this, the first aspect of the utility model provides a cover assembly, which is used for a cooking utensil, and the cooking utensil is provided with a cooking cavity. The cover assembly includes a cover body, an exhaust assembly and a fan assembly, the exhaust assembly is arranged on the cover body, and the fan assembly is arranged on a side of the cover body close to the cooking cavity. The fan assembly includes a rotating shaft and at least two groups of blade groups, the rotating shaft is connected to the cover body, and the at least two groups of blade groups are arranged along the axial direction of the rotating shaft and connected to the rotating shaft; wherein, when the exhaust assembly exhausts air, the gas passing through the exhaust assembly can drive the fan assembly to rotate.

[0007] The present application provides a cover assembly, which is used for a cooking utensil, and the cooking utensil is provided with a cooking cavity. The cover assembly includes a cover body, an exhaust assembly and a fan assembly, wherein the exhaust assembly is provided on the cover body, and the fan assembly is provided on a side of the cover body close to the cooking cavity. The fan assembly includes a rotating shaft and at least two blade groups, and the rotating shaft is connected to the cover body, and the at least two blade groups are arranged along the axial direction of the rotating shaft and connected to the rotating shaft; wherein when the exhaust assembly exhausts gas, the gas passing through the exhaust assembly can drive the fan assembly to rotate. The cover assembly can be provided to protect the cooking cavity of the cooking utensil, and the cooking cavity can be sealed by providing the cover body to cover the cooking cavity. When the cooking utensil is working, the cover body can maintain pressure inside the cooking cavity to improve the cooking effect. The cooking utensil guides gas to the cooking cavity through the exhaust assembly to adjust the air pressure in the cooking cavity, and then enriches the working mode of the cooking utensil by adjusting the air pressure, improves the cooking effect, and also improves the taste of food. When the cooking appliance is cooking food, the temperature in the cooking cavity rises, and the air pressure in the cooking cavity increases. When the cooking appliance is in the exhaust state, the internal air pressure is greater than the external air pressure, the boiling point of the liquid food in the cooking cavity is reduced, the liquid food boils suddenly, and bubbles are formed in the liquid food. The bubbles overflow upward under the action of the internal and external pressure difference of the cooking appliance and the flowing gas. The rapid flow of the gas will drive the fan assembly arranged on the side of the cover body close to the cooking cavity. The rotation of the fan assembly will stir the gas and bubble mixture overflowing upward. The gas continues to flow, and the bubbles formed by the food will be destroyed by the fan assembly, thereby reducing the probability of liquid food overflowing. By arranging at least two groups of blade groups along the axial direction of the rotating shaft, the pressure-bearing area of ​​the blades can be increased, and the driving force of the airflow on the fan assembly can be increased, so that the fan assembly can be started to rotate after being impacted by the airflow, thereby effectively The fan assembly is beneficial to destroying food bubbles and improving the anti-overflow effect. Since the food bubbles burst and reform into liquid food after being destroyed by the fan, some of the reformed liquid food will remain on the blades of the fan. By setting at least two groups of blade groups, the blade spacing can be increased while ensuring the anti-overflow effect, which is convenient for the liquid food remaining on the blades to fall off, avoiding obstruction of the rotation of the fan assembly, and avoiding blade breakage caused by excessive food loading. The layered blade groups can facilitate the user to clean the fan assembly, and also realize the layered destruction of food bubbles, improve the bubble breaking efficiency in the anti-overflow process, and improve the working effect of the cooking appliance. At the same time, by setting a gas-driven fan assembly to destroy the overflow bubbles, it is no longer necessary to set a separate motor drive, thereby reducing the working noise of the cooking appliance, reducing the equipment assembly cost, and saving energy and reducing the use cost.

[0008] In addition, the cover assembly in the above technical solution provided by the utility model may also have the following additional technical features:

[0009] In some technical solutions of the present invention, optionally, at least two groups of blade groups include multiple first blades and multiple second blades, the multiple first blades are arranged along the circumference of the rotating shaft, and the multiple second blades are arranged along the circumference of the rotating shaft and are located on one side of the multiple first blades in the axial direction of the rotating shaft.

[0010] In this technical solution, at least two groups of blades include a plurality of first blades and a plurality of second blades, the plurality of first blades are arranged along the circumference of the rotating shaft, and the plurality of second blades are arranged along the circumference of the rotating shaft and are located on one side of the plurality of first blades in the axial direction of the rotating shaft. The plurality of first blades and the plurality of second blades arranged in the circumference of the rotating shaft can rotate along the rotating shaft under the impact of the airflow, thereby achieving the destruction of the bubbles overflowing upwards. By arranging the plurality of first blades and the plurality of second blades in layers in the axial direction of the rotating shaft, the weight of the single-layer blades can be reduced while achieving the anti-overflow effect, reducing the load of the blades, thereby increasing the driving force of the airflow on the fan assembly, thereby facilitating the exhaust airflow of the cooking utensil to drive the fan assembly to rotate to complete the destruction of the food bubbles, thereby improving the anti-overflow effect, and also avoiding the blade breakage caused by excessive food loading. The plurality of first blades and the plurality of second blades arranged in layers can facilitate the user to clean the fan assembly, while improving the bubble breaking efficiency in the anti-overflow process, and also improving the working effect of the cooking utensil.

[0011] In some technical solutions of the present utility model, optionally, in the axial direction of the rotating shaft, a plurality of first blades and a plurality of second blades are arranged opposite to each other.

[0012] In this technical solution, in the axial direction of the rotating shaft, multiple first blades and multiple second blades are relatively arranged. When the cooking appliance is exhausted, the bubbles in the food can be broken by setting the multiple first blades and multiple second blades that are relatively arranged, thereby improving the bubble breaking effect of the fan assembly. At the same time, the layered blade group can increase the pressure-bearing area of ​​the blades, increase the driving force of the airflow on the fan assembly, and thus facilitate the exhaust airflow of the cooking appliance to drive the fan assembly to rotate to complete the destruction of the food bubbles, thereby improving the anti-overflow effect. While ensuring the anti-overflow effect, the blade spacing can be increased to facilitate the falling of liquid food retained on the blades, avoid obstruction of the rotation of the fan assembly, and avoid excessive food loading causing blade breakage. At the same time, due to the relative arrangement of the multiple first blades and the multiple second blades, the shapes of the first blades and the second blades can be the same, thereby reducing the difficulty of injection molding of the blades, facilitating the production and installation of the fan assembly, reducing the difficulty of injection molding and reducing the installation cost of the fan assembly.

[0013] In some technical solutions of the present invention, optionally, in the axial direction of the rotating shaft, a plurality of first blades and a plurality of second blades are arranged alternately.

[0014] In this technical solution, in the axial direction of the rotating shaft, a plurality of first blades and a plurality of second blades are arranged in a staggered manner. When the cooking utensil is exhausted, under the action of the pressure difference between the inside and outside of the cooking utensil and the airflow, when the food bubbles flow through the fan assembly along with the airflow, the staggered plurality of first blades and the plurality of second blades rotate under the impetus of the airflow. The two staggered groups of blades can increase the contact area between the blades and the airflow, increase the driving force of the airflow on the fan assembly, and facilitate the exhaust airflow of the cooking utensil to drive the fan assembly to rotate to complete the destruction of the food bubbles, thereby improving the anti-overflow effect. Since the food bubbles rupture and reform into liquid food after being destroyed by the fan, part of the reformed liquid food will remain on the blades of the fan. By setting at least two groups of blades, the distance between the blades can be increased while ensuring the anti-overflow effect, which facilitates the falling off of the liquid food remaining on the blades, avoids the fan assembly from being blocked from rotating, and also avoids the blades from being broken due to excessive food loading.

[0015] In some technical solutions of the present utility model, optionally, the number of the plurality of first blades is the same as or different from the number of the plurality of second blades.

[0016] In this technical solution, the number of the plurality of first blades is the same as or different from the number of the plurality of second blades. At least two blade groups of the same number can be provided, thereby reducing the process steps and installation costs during assembly. Different numbers of the plurality of first blades and the plurality of second blades can also be designed according to the bubble density at different levels of the at least two blade groups, which can further enhance the destruction of the bubbles overflowing upward by the fan assembly and improve the anti-overflow effect of the cooking utensil.

[0017] In some technical solutions of the present utility model, optionally, the number of the plurality of first blades is less than or equal to 5; and / or the number of the plurality of second blades is less than or equal to 5.

[0018] In this technical solution, the number of the plurality of first blades is less than or equal to 5; and / or the number of the plurality of second blades is less than or equal to 5. By limiting the number of the plurality of first blades and the plurality of second blades, the mass of the blades in the blade group can be reduced, the load of the blades can be reduced, and the resistance of the fan assembly when rotating can be reduced. At the same time, the driving force of the airflow on the fan assembly can be increased, so that the exhaust airflow of the cooking utensil drives the fan assembly to rotate to destroy the bubbles of the food, thereby improving the anti-overflow effect.

[0019] In some technical solutions of the present utility model, optionally, a first gap is provided between two adjacent groups of blades in at least two groups of blades, and a width of the first gap in the axial direction of the rotating shaft is greater than or equal to 8 mm.

[0020] In this technical solution, there is a first gap between two adjacent groups of blade groups in at least two groups of blade groups, and the width of the first gap in the axial direction of the rotating shaft is greater than or equal to 8 mm. By setting the first gap between two adjacent groups of blade groups, smooth airflow between the two groups of blade groups can be ensured, the rotation efficiency of the fan can be improved, and the bubble breaking effect of the fan assembly can be improved. At the same time, by setting the width of the first gap between two adjacent groups of blade groups in at least two groups of blade groups in the axial direction of the rotating shaft to be greater than or equal to 8 mm, multi-stage bubble breaking can be achieved and the bubble breaking effect can be improved.

[0021] In some technical solutions of the present utility model, optionally, the diameter of the circle where the outer edge of each blade group in the at least two blade groups is located is greater than or equal to 50 mm.

[0022] In this technical solution, the diameter of the circle where the outer edge of each blade group in at least two blade groups is located is greater than or equal to 50 mm, thereby increasing the diameter of the blade rotation area, increasing the blade pressure-bearing area, and reducing the power required to drive the fan assembly, thereby facilitating the exhaust airflow of the cooking utensil to drive the fan assembly to rotate to complete the destruction of food bubbles, thereby improving the anti-overflow effect.

[0023] In some technical solutions of the utility model, optionally, the cover assembly also includes a guide component, the guide component cover is arranged at one end of the exhaust assembly close to the cooking cavity, the guide component is provided with a through hole, or there is a second gap between the guide component and the cover body; the through hole or the second gap faces the fan assembly.

[0024] In this technical solution, the cover assembly also includes a flow guide component, which is covered at one end of the exhaust assembly close to the cooking cavity, and the flow guide component is provided with a through hole, or a second gap is provided between the flow guide component and the cover body; the through hole or the second gap faces the fan assembly, and the direction of the airflow can be controlled by arranging the flow guide component. When the cooking utensil is exhausted, under the action of the internal and external pressure difference, the airflow can pass through the fan assembly before entering the exhaust assembly under the action of the flow guide component, thereby reducing the probability of food bubbles directly overflowing from the cooking utensil without being subjected to bubble breaking treatment, improving the bubble breaking effect of the fan assembly, and enhancing the anti-overflow effect of the cooking utensil.

[0025] In some technical solutions of the present invention, optionally, the fan assembly is opposite to an end of the exhaust assembly close to the cooking cavity.

[0026] In this technical solution, the fan assembly is opposite to one end of the exhaust assembly close to the cooking cavity. When the cooking utensil is exhausted, since the internal air pressure of the cooking utensil is greater than the external air pressure, the gas in the cooking utensil flows rapidly under the action of the internal and external pressure difference, and the airflow is discharged to the outside of the cooking utensil through the exhaust assembly. By arranging the fan assembly to be opposite to one end of the exhaust assembly close to the cooking cavity, the airflow can first flow through the fan assembly when flowing out of the exhaust assembly, and the fan assembly destroys the food bubbles entrained in the airflow, thereby reducing the probability of food overflow, improving the efficiency of destroying food bubbles, and enhancing the overflow prevention effect.

[0027] A second aspect of the utility model provides a cooking utensil, comprising a cover assembly as described in any one of the above technical solutions.

[0028] The cooking utensil provided in the present application comprises a cover assembly as in any one of the above technical solutions, and thus the cooking utensil has all the beneficial effects of the cover assembly in any one of the above technical solutions.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0039] Refer to the following Figures 1 to 4 A lid assembly 100 and a cooking appliance 200 according to some embodiments of the present invention are described.

[0040] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a cover assembly 100 is provided, and the cover assembly 100 is used for a cooking utensil 200, and the cooking utensil 200 is provided with a cooking cavity 220. The cover assembly 100 includes a cover body 110, an exhaust assembly 120 and a fan assembly 130. The exhaust assembly 120 is arranged on the cover body 110, and the fan assembly 130 is arranged on a side of the cover body 110 close to the cooking cavity 220. The fan assembly 130 includes a rotating shaft 132 and at least two groups of blade groups 134. The rotating shaft 132 is connected to the cover body 110, and the at least two groups of blade groups 134 are arranged along the axial direction of the rotating shaft 132 and are connected to the rotating shaft 132; wherein, when the exhaust assembly 120 exhausts air, the gas passing through the exhaust assembly 120 can drive the fan assembly 130 to rotate.

[0041] The present application provides a cover assembly 100, which is used for a cooking utensil 200. The cooking utensil 200 is provided with a cooking cavity 220. The cover assembly 100 includes a cover body 110, an exhaust assembly 120 and a fan assembly 130. The exhaust assembly 120 is arranged on the cover body 110, and the fan assembly 130 is arranged on a side of the cover body 110 close to the cooking cavity 220. The fan assembly 130 includes a rotating shaft 132 and at least two groups of blade groups 134. The rotating shaft 132 is connected to the cover body 110, and the at least two groups of blade groups 134 are arranged along the axial direction of the rotating shaft 132 and are connected to the rotating shaft 132. When the exhaust assembly 120 exhausts air, the gas passing through the exhaust assembly 120 can drive the fan assembly 130 to rotate. The cover assembly 100 can protect the cooking cavity 220 of the cooking utensil 200. At the same time, the cooking cavity 220 can be sealed by setting a cover body 110 to cover the cooking cavity 220. When the cooking utensil 200 is working, the cover body 110 can maintain the pressure inside the cooking cavity 220 to improve the cooking effect. The cooking utensil 200 guides air to the cooking cavity 220 through the exhaust assembly 120 to adjust the air pressure in the cooking cavity 220, and then enriches the working mode of the cooking utensil 200 by adjusting the air pressure, thereby improving the cooking effect and also improving the taste of the food. When the cooking device 200 is cooking food, the temperature in the cooking cavity 220 rises, and the air pressure in the cooking cavity 220 increases. When the cooking device 200 is in the exhaust state, the internal air pressure is greater than the external air pressure, the boiling point of the liquid food in the cooking cavity 220 decreases, and the liquid food boils suddenly. The liquid food forms bubbles 150, which overflow upward under the action of the internal and external pressure difference of the cooking device 200 and the flowing gas. The rapid flow of the gas will drive the fan assembly 130 disposed on the side of the cover body 110 close to the cooking cavity 220. The rotation of the fan assembly 130 will stir the mixture of the gas and the bubbles 150 overflowing upward. The gas continues to flow, and the bubbles 150 formed by the food will be destroyed by the fan assembly 130, thereby reducing the probability of liquid food overflowing. By providing at least two groups of blade groups 134 arranged along the axial direction of the rotating shaft 132, The pressure-bearing area of ​​the blades can be increased, and the driving force of the airflow on the fan assembly 130 can be increased, so that the exhaust airflow of the cooking appliance 200 can drive the fan assembly 130 to rotate to complete the destruction of the food bubbles 150, thereby improving the anti-overflow effect. Since the food bubbles 150 are broken and reformed into liquid food after being destroyed by the fan, part of the reformed liquid food will remain on the blades of the fan. By setting at least two groups of blade groups 134, the blade spacing can be increased while ensuring the anti-overflow effect, so that the liquid food remaining on the blades can fall off, and the rotation of the fan assembly 130 can be avoided. It can also avoid the blades from breaking due to excessive food mounting. The layered blade groups 134 can facilitate the user to clean the fan assembly 130, and also realize the layered destruction of the food bubbles 150, thereby improving the bubble breaking efficiency during the anti-overflow process and improving the working effect of the cooking appliance 200.

[0042] Specifically, Figure 2 As shown, the air bubbles 150 rise in the cooking appliance 200 , pass through the fan assembly 130 , enter the exhaust assembly 120 , and then exit the cooking appliance 200 .

[0043] Specifically, Figure 1 As shown, the axial direction of the rotating shaft 132 is direction T.

[0044] Specifically, Figure 2 As shown, due to the pressure difference between the inside and outside of the cooking utensil 200, the bubbles 150 overflow upward from direction a into the fan assembly 130. The bubbles 150 are broken by the fan assembly 130 and remain in the cooking utensil, reducing the probability of overflow.

[0045] Furthermore, the cover assembly 100 may include a face cover and a steel cover. The face cover may be a plastic cover or a metal cover. The steel cover is non-detachably mounted on the face cover. The steel cover is the cover body mentioned in the present application.

[0046] The cover assembly 100 may also include a face cover, a steel cover and a cover plate. The face cover may be a plastic cover. The steel cover is fixedly mounted on the face cover. The cover plate is detachably mounted on the steel cover. The cover plate is the cover body 110 mentioned in this application.

[0047] The cover assembly 100 may also include a surface cover, an inner cover and a steel cover. The surface cover may be a plastic cover, and the inner cover may also be a plastic cover. The inner cover is buckled with the surface cover, and the steel cover is non-detachably mounted on the inner cover. The steel cover is the cover body mentioned in this application.

[0048] The cover assembly 100 may also include a face cover, an inner cover, a steel cover and a cover plate. The face cover may be a plastic cover, and the inner cover may also be a plastic cover. The inner cover is buckled with the face cover, the steel cover is non-detachably mounted on the inner cover, and the cover plate is detachably mounted on the inner cover. The cover plate is the cover body 110 mentioned in this application.

[0049] The cover assembly 100 may also include a face cover, an inner cover, a lock and a cover plate. The face cover may be a plastic cover, and the inner cover may also be a plastic cover. The inner cover is buckled with the face cover, the lock is non-detachably mounted on the inner cover, and the cover plate is detachably mounted on the inner cover. The cover plate is the cover body 110 mentioned in this application.

[0050] Furthermore, the steel cover and / or the lock buckle can rotate relative to the pot body, and the steel cover and / or the cover plate are used to bear the pressure of the cooking cavity 220.

[0051] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0052] At least two groups of blade groups 134 include multiple first blades 136 and multiple second blades 138. The multiple first blades 136 are arranged along the circumference of the rotating shaft 132, and the multiple second blades 138 are arranged along the circumference of the rotating shaft 132 and are located on one side of the multiple first blades 136 in the axial direction of the rotating shaft 132.

[0053] In this embodiment, if Figure 3 and Figure 4 As shown, at least two groups of blade groups 134 include multiple first blades 136 and multiple second blades 138. The multiple first blades 136 are arranged along the circumference of the rotating shaft 132, and the multiple second blades 138 are arranged along the circumference of the rotating shaft 132 and are located on one side of the multiple first blades 136 in the axial direction of the rotating shaft 132. The plurality of first blades 136 and the plurality of second blades 138 arranged circumferentially of the rotating shaft 132 can rotate along the rotating shaft 132 under the impact of the airflow, thereby destroying the bubbles 150 overflowing upward. By arranging the plurality of first blades 136 and the plurality of second blades 138 in layers in the axial direction of the rotating shaft 132, the weight of a single layer of blades can be reduced while achieving an anti-overflow effect, thereby reducing the load on the blades, thereby increasing the driving force of the airflow on the fan assembly 130, thereby facilitating the exhaust airflow of the cooking utensil 200 to drive the fan assembly 130 to rotate and complete the destruction of the food bubbles 150, thereby improving the anti-overflow effect and preventing the blades from breaking due to excessive food loading. The plurality of first blades 136 and the plurality of second blades 138 arranged in layers can facilitate the user to clean the fan assembly 130, thereby improving the bubble breaking efficiency during the anti-overflow process and improving the working effect of the cooking utensil 200.

[0054] Specifically, Figure 4 As shown, the circumferential direction of the rotating shaft 132 is direction Z.

[0055] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0056] In the axial direction of the rotating shaft 132 , a plurality of first blades 136 and a plurality of second blades 138 are arranged opposite to each other.

[0057] In this embodiment, if Figure 1 and Figure 4As shown, in the axial direction of the rotating shaft 132, a plurality of first blades 136 and a plurality of second blades 138 are arranged relatively to each other. When the cooking utensil 200 is exhausted, the food bubbles 150 can be broken by setting the plurality of first blades 136 and the plurality of second blades 138 arranged relatively to each other, thereby improving the bubble breaking effect of the fan assembly 130. At the same time, the layered blade group 134 can increase the pressure bearing area of ​​the blades, increase the driving force of the airflow on the fan assembly 130, and thus facilitate the exhaust airflow of the cooking utensil 200 to drive the fan assembly 130 to rotate to complete the destruction of the food bubbles 150, thereby improving the anti-overflow effect. The blade spacing can be increased while ensuring the anti-overflow effect, so that the liquid food retained on the blades can fall off, and the rotation of the fan assembly 130 can be avoided from being blocked, and the blades can be avoided from being broken due to excessive food loading. At the same time, since the plurality of first blades 136 and the plurality of second blades 138 are arranged relatively to each other, the shapes of the first blades 136 and the second blades 138 can be the same, thereby reducing the difficulty of injection molding of the blades, facilitating the production and installation of the fan assembly 130, reducing the difficulty of injection molding and reducing the installation cost of the fan assembly 130.

[0058] Specifically, the relative arrangement of the multiple first blades 136 and the multiple second blades 138 can be: on the radial cross-section of the rotating shaft 132, the multiple first blades 136 and the multiple second blades 138 are projected along the axial direction of the rotating shaft 132 respectively, and the projection areas formed by the multiple first blades 136 and the multiple second blades 138 on the cross-section partially overlap or completely overlap. It can also be understood that the first blades 136 and the second blades 138 are arranged one-to-one in the axial direction of the rotating shaft 132, or part of the first blades 136 and part of the second blades 138 are arranged one-to-one in the axial direction of the rotating shaft 132.

[0059] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0060] like Figure 4 As shown, in the axial direction of the rotating shaft 132 , a plurality of first blades 136 and a plurality of second blades 138 are arranged alternately.

[0061] In this embodiment, in the axial direction of the rotating shaft 132 , the plurality of first blades 136 and the plurality of second blades 138 are arranged alternately. When the cooking utensil 200 is exhausted, under the action of the pressure difference between the inside and outside of the cooking utensil 200 and the airflow, when the food bubbles 150 flow through the fan assembly 130 with the airflow, the multiple first blades 136 and the multiple second blades 138 arranged in an alternating manner rotate under the push of the airflow. The two sets of blades arranged in an alternating manner can increase the contact area between the blades and the airflow, improve the driving force of the airflow on the fan assembly 130, facilitate the start-up of the fan assembly 130, and facilitate the exhaust airflow of the cooking utensil 200 to drive the fan assembly 130 to rotate to complete the destruction of the food bubbles 150, thereby improving the anti-overflow effect. Since the food bubbles 150 rupture and reform into liquid food after being destroyed by the fan, part of the reformed liquid food will remain on the blades of the fan. By providing at least two sets of blade groups 134, the blade spacing can be increased while ensuring the anti-overflow effect, thereby facilitating the falling off of the liquid food remaining on the blades, thereby avoiding obstruction of the rotation of the fan assembly 130, and avoiding excessive loading of food and resulting in blade breakage.

[0062] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0063] The number of the plurality of first blades 136 may be the same as or different from the number of the plurality of second blades 138 .

[0064] In this embodiment, the number of the plurality of first blades 136 is the same as or different from the number of the plurality of second blades 138. At least two blade groups 134 of the same number may be provided, thereby reducing the process steps and installation costs during assembly. Different numbers of the plurality of first blades 136 and the plurality of second blades 138 may also be designed for the density of bubbles 150 at different levels of the at least two blade groups 134, which may further enhance the destruction of the bubbles 150 overflowing upward by the fan assembly 130 and improve the anti-overflow effect of the cooking appliance 200.

[0065] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

By limiting the number of the plurality of first blades 136 and the plurality of second blades 138, the mass of the blades in the blade set 134 can be reduced, the load of the blades can be reduced, and the resistance of the fan assembly 130 when rotating can be reduced. At the same time, the driving force of the airflow on the fan assembly 130 can be increased, so that the exhaust airflow of the cooking utensil 200 drives the fan assembly 130 to rotate to complete the destruction of the food bubbles 150, thereby improving the anti-overflow effect.

[0068] Specifically, the number of the plurality of first blades 136 is less than or equal to 5 and greater than or equal to 2, and / or the number of the plurality of second blades 138 is less than or equal to 5 and greater than or equal to 2. The number of the plurality of first blades 136 can be 2, 3, 4, or 5. The number of the plurality of second blades 138 can be 2, 3, 4, or 5.

[0069] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0070] A first gap 135 is defined between two adjacent blade groups 134 in the at least two blade groups 134 . The width of the first gap 135 in the axial direction of the rotating shaft 132 is greater than or equal to 8 mm.

[0071] In this embodiment, there is a first gap 135 between two adjacent groups of blade groups 134 in at least two groups of blade groups 134, and the width of the first gap 135 in the axial direction of the rotating shaft 132 is greater than or equal to 8 mm. By setting the first gap 135 between two adjacent groups of blade groups 134, it is possible to ensure smooth airflow between the two groups of blade groups 134, improve the rotation efficiency of the fan, and enhance the bubble breaking effect of the fan assembly 130. At the same time, by setting the width of the first gap 135 between two adjacent groups of blade groups 134 in at least two groups of blade groups 134 in the axial direction of the rotating shaft 132 to be greater than or equal to 8 mm and less than or equal to 12 mm, multi-stage bubble breaking can be achieved and the bubble breaking effect can be improved.

[0072] Specifically, Figure 1 As shown, the width of the first gap 135 between two adjacent groups of blade groups 134 in at least two groups of blade groups 134 in the axial direction of the rotating shaft 132 is L, and the width of the first gap 135 between two adjacent groups of blade groups 134 in at least two groups of blade groups 134 in the axial direction of the rotating shaft 132 is L, which can be 8 mm, 9 mm, 10 mm, 11 mm, or 12 mm.

[0074] The diameter of the circle where the outer edge of each blade group 134 of the at least two blade groups 134 lies is greater than or equal to 50 mm.

[0075] In this embodiment, the diameter of the circle where the outer edge of each blade group 134 in at least two blade groups 134 is located is greater than or equal to 50 mm and less than or equal to 80 mm, thereby increasing the diameter of the blade rotation area and the blade pressure-bearing area, thereby increasing the driving force of the airflow on the fan assembly 130, thereby facilitating the exhaust airflow of the cooking utensil 200 to drive the fan assembly 130 to rotate to complete the destruction of the food bubbles 150, thereby improving the anti-overflow effect.

[0076] Specifically, Figure 3 As shown, the diameter of the circle where the outer edge of each blade group 134 in at least two blade groups 134 is located is H, and the diameter H of the circle where the outer edge of each blade group 134 in at least two blade groups 134 is located can be 50 mm, the diameter H of the circle where the outer edge of each blade group 134 in at least two blade groups 134 is located can be 60 mm, the diameter H of the circle where the outer edge of each blade group 134 in at least two blade groups 134 is located can be 70 mm, and the diameter H of the circle where the outer edge of each blade group 134 in at least two blade groups 134 is located can be 80 mm.

[0077] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0078] The cover assembly 100 also includes a guide component 140, which is covered at one end of the exhaust assembly 120 close to the cooking cavity 220. The guide component 140 is provided with a through hole 142, or a second gap 144 is provided between the guide component 140 and the cover body 110; the through hole 142 or the second gap 144 faces the fan assembly 130.

[0079] In this embodiment, the cover assembly 100 also includes a guide component 140, which is covered at one end of the exhaust assembly 120 close to the cooking cavity 220. The guide component 140 is provided with a through hole 142, or a second gap 144 is provided between the guide component 140 and the cover body 110; the through hole 142 or the second gap 144 is directed toward the fan assembly 130. By providing the guide component 140, the direction of the airflow can be controlled. When the cooking utensil 200 is exhausted, under the action of the internal and external pressure difference, the airflow can pass through the fan assembly 130 before entering the exhaust assembly 120 under the action of the guide component 140, thereby reducing the direct overflow of food bubbles 150 from the cooking utensil 200 without being subjected to the bubble breaking treatment, improving the bubble breaking effect of the fan assembly 130, and enhancing the anti-overflow effect of the cooking utensil 200.

[0080] Specifically, Figure 2 As shown, under the action of the pressure difference of the cooking utensil 200, the gas moves upward along direction a carrying the bubble 150, passes through the fan assembly 130, enters the guide component 140 along direction b, flows along direction c, and then flows out of the cooking utensil 200 through direction d, thereby achieving exhaust.

[0081] This embodiment provides a cover assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0082] The fan assembly 130 is opposite to an end of the exhaust assembly 120 that is close to the cooking cavity 220 .

[0083] In this embodiment, the fan assembly 130 is opposite to one end of the exhaust assembly 120 close to the cooking cavity 220. When the cooking utensil 200 is exhausted, since the internal air pressure of the cooking utensil 200 is greater than the external air pressure, the gas in the cooking utensil 200 flows rapidly due to the pressure difference between the inside and the outside, and the airflow is discharged to the outside of the cooking utensil 200 through the exhaust assembly 120. By arranging the fan assembly 130 to be opposite to one end of the exhaust assembly 120 close to the cooking cavity 220, the airflow can first flow through the fan assembly 130 when flowing out of the exhaust assembly 120, and the fan assembly 130 destroys the food bubbles 150 entrained in the airflow, thereby reducing the probability of food overflow, improving the efficiency of destroying the food bubbles 150, and improving the anti-overflow effect.

[0084] Specifically, the arrangement of the fan assembly 130 and the end of the exhaust assembly 120 close to the cooking cavity 220 can be: the fan assembly 130 is arranged at the end of the exhaust assembly 120 close to the cooking cavity 220, so that the axial direction of the rotating shaft 132 in the fan assembly 130 is the same as the air intake direction of the exhaust assembly 120. Alternatively, the air outlet end of the fan assembly 130 and the air intake end of the exhaust assembly 120 are connected to each other, and the airflow in the cooking cavity 220 passes through the fan assembly 130 and the exhaust assembly 120 in sequence and then is discharged to the outside of the cooking appliance 200.

[0085] For example, the axis of the exhaust assembly 120 is arranged to coincide with the axis of the fan assembly 130 , that is, the exhaust assembly 120 and the fan assembly 130 are arranged coaxially.

[0086] The cross section of the fan assembly 130 in the rotation axis direction may also be arranged to completely overlap or partially overlap with the cross section of the exhaust passage of the exhaust assembly 120 in the radial direction.
