Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to a cover assembly and a cooking utensil. Background Art

[0002] At present, in the relevant technology, the internal temperature of the cooking appliance rises when it is working, and the gas pressure in the cooking cavity of the cooking appliance rises. When the cooking appliance is in the exhaust state, the internal gas pressure decreases in a short time, the boiling point of the liquid food decreases, and the liquid food boils again to form bubbles, resulting in a high probability of the food overflowing from the cooking cavity. 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 present invention 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. The cooking utensil is provided with a cooking cavity. The cover assembly includes a cover body and an anti-overflow component. The anti-overflow component is connected to the cover body and is located on a side of the cover body close to the cooking cavity; wherein a gap is provided between an edge of the anti-overflow component on a side close to the cover body and the cover body.

[0007] The present application provides a cover assembly, which is used for a cooking utensil. The cooking utensil is provided with a cooking cavity. The cover assembly includes a cover body and an anti-overflow component. The anti-overflow component is connected to the cover body and is located on a side of the cover body close to the cooking cavity; wherein a gap exists between the edge of the side of the anti-overflow component close to the cover body and the cover body. The cover assembly can protect the cooking utensil. At the same time, when the cover assembly is in a closed state, the pressure of the cooking cavity of the cooking utensil can be maintained. When the cooking utensil is working, the temperature in the cooking cavity rises. Since the cover assembly seals the cooking cavity through the cover body, the pressure in the cooking cavity rises during the operation of the cooking utensil. The internal gas pressure of the cooking utensil is greater than the external gas pressure. When the cooking utensil is venting, the gas pressure in the cooking cavity drops in a short time. Since the temperature of the food in the cooking cavity drops slowly and the boiling point of the liquid decreases, the liquid food will boil in a short time. Then, the bubbles formed by the sudden boiling of the liquid food can be broken by the anti-overflow component. The anti-overflow component can also destroy the bubbles that float up under the action of pressure and flowing gas during the exhaust of the cooking appliance, thereby reducing the probability of liquid food overflowing. The anti-overflow component can also be used to increase the allowable range of the heating power of the cooking appliance, extend the continuous exhaust time of the cooking appliance, improve the cooking effect of the food, and improve the overall cleanliness of the cooking appliance, making it easier for users to clean the cooking appliance after cooking, thereby improving the user experience of the cooking appliance. At the same time, the gap between the cover and the anti-overflow component can further improve the anti-overflow effect of the cooking appliance.

[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, the distance between the edge of the anti-overflow component on the side close to the cover body and the cover body is less than or equal to 5 mm.

[0010] In this technical solution, the distance between the edge of the anti-overflow component close to the cover body and the cover body is less than or equal to 5 mm, so that when the liquid food suddenly boils, some solid food can be prevented from entering the anti-overflow component under the action of air pressure and steam, avoiding the accumulation of solid food in the anti-overflow component, thereby reducing the probability of clogging of the anti-overflow component. By setting the size of the gap, further overflow prevention of the cooking utensils can be achieved, and the anti-overflow effect can be improved. At the same time, it helps the anti-overflow component to extend the continuous exhaust time of the cooking utensils, improve the cooking effect of the cooking utensils on the food, reduce the accumulation inside the anti-overflow component, and improve the cleanliness inside the cooking utensils, making it easier for users to clean the anti-overflow component.

[0011] In some technical solutions of the utility model, optionally, the cover assembly also includes an exhaust assembly, which is arranged on the cover body; the overflow prevention component includes a first body, which is connected to the cover body, and the first body has a first cavity and a first through hole, and the first cavity is connected to the exhaust assembly, and the first cavity can be connected to the cooking cavity through the first through hole.

[0012] In this technical solution, the cover assembly also includes an exhaust assembly, which is arranged on the cover body; the overflow prevention component includes a first body, which is connected to the cover body, and the first body has a first cavity and a first through hole, and the first cavity is connected to the exhaust assembly, and the first cavity can be connected to the cooking cavity through the first through hole. The cooking utensil guides the gas to the cooking cavity through the exhaust assembly, adjusts 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 utensil is working, the gas in the cooking cavity enters the first cavity through the first through hole under the action of pressure, and is then guided by the exhaust assembly connected to the first cavity, thereby realizing the discharge of the gas in the cooking utensil, adjusting the air pressure, and improving the cooking effect. At the same time, the first body can also destroy the bubbles formed by the liquid food, so that the food can be deposited in the cooking cavity and the first overflow prevention part, and the bubbles of the food are broken to avoid food overflow, which can improve the overall cleanliness of the cooking utensil, facilitate users to clean the cooking utensil after cooking, and improve the use experience of the cooking utensil.

[0013] In some technical solutions of the present invention, optionally, the first cavity includes a first anti-overflow cavity and a second anti-overflow cavity, the first anti-overflow cavity is connected to the first through hole; the second anti-overflow cavity is connected to the first anti-overflow cavity, and the exhaust assembly is opposite to the second anti-overflow cavity.

[0014] In this technical solution, the first cavity includes a first anti-overflow cavity and a second anti-overflow cavity, the first anti-overflow cavity is connected to the first through hole; the second anti-overflow cavity is connected to the first anti-overflow cavity, and the exhaust component is opposite to the second anti-overflow cavity. When the cooking utensil is working, the bubbles and gas formed by the overflowing liquid food will pass through the first cavity. Since the first anti-overflow cavity and the second anti-overflow cavity are arranged in the first cavity, the bubbles and gas formed by the food can be destroyed by the first through hole in the process of passing through the first anti-overflow cavity, and the bubbles will also be destroyed when contacting the inner wall of the anti-overflow cavity, and the gas and part of the liquid food can enter the second anti-overflow cavity. The second through hole of the second anti-overflow cavity further destroys the food bubbles, reducing the probability of the food bubbles overflowing with the discharged gas, thereby extending the exhaust channel of the cooking utensil 200, improving the destruction efficiency of the food bubbles, and improving the bubble breaking effect of the anti-overflow component 120.

[0015] Specifically, the first cavity may be an anti-overflow cavity. It may be designed that the first cavity contains only the first anti-overflow cavity, or it may be designed that the first cavity contains only the second anti-overflow cavity.

[0016] In some technical solutions of the present utility model, optionally, the anti-overflow component also includes a partition, which is connected to the first body and is located in the first cavity to separate the first cavity into a first anti-overflow cavity and a second anti-overflow cavity.

[0017] In this technical solution, the anti-overflow component also includes a partition, which is connected to the first body and is located in the first cavity, dividing the first cavity into a first anti-overflow cavity and a second anti-overflow cavity. When liquid food flows through the first cavity, the partition will block the food and play an anti-overflow role. At the same time, by setting the partition to separate the first anti-overflow cavity and the second anti-overflow cavity, the anti-overflow effect can be further improved, the exhaust time can be extended, and the cooking effect can be improved. The provision of a partition can prevent solid food from overflowing, preventing the solid food from overflowing with the boiling liquid in the event of a sudden change in pressure, thereby improving the anti-overflow effect of the overall cooking utensil.

[0019] In this technical solution, the overflow prevention component also includes a second body, which is arranged in the first cavity. The outer wall of the second body and the inner wall of the first body enclose a first overflow prevention cavity. The second body has a second overflow prevention cavity. The first overflow prevention cavity and the second overflow prevention cavity are separated by the second body. The second body is arranged in the first body, which can further improve the overflow prevention effect, extend the exhaust time, and enhance the cooking effect.

[0020] Specifically, the second body and the first body may be an integrated structure or a split structure.

[0021] In some technical solutions of the present utility model, optionally, the side wall of the second body is provided with at least one second through hole, and the first anti-overflow cavity is connected with the second anti-overflow cavity through the at least one second through hole.

[0022] In this technical solution, the side wall of the second body is provided with at least one second through hole, and the first anti-overflow cavity is connected with the second anti-overflow cavity through the at least one second through hole. The at least one second through hole can improve the flow of overflow gas into the second anti-overflow cavity through the first anti-overflow cavity, improve the gas conduction efficiency, facilitate the exhaust of the cooking utensil, and improve the cooking effect of the cooking utensil.

[0023] Specifically, the number of the second through holes can be designed according to the working parameters of the cooking appliance.

[0024] In some technical solutions of the present invention, optionally, the anti-overflow component also includes a seal, and the seal is arranged between the first body and the second body.

[0025] In this technical solution, the anti-overflow component also includes a seal, which is arranged between the first body and the second body to seal the gap between the first body and the second body to prevent food from remaining in the gap between the first body and the second body after the anti-overflow barrier, thereby improving the anti-overflow effect and facilitating users to clean the cooking utensils.

[0026] In some technical solutions of the present utility model, optionally, the volume of the first anti-overflow cavity is greater than the volume of the second anti-overflow cavity.

[0027] In this technical solution, the volume of the first anti-overflow cavity is greater than that of the second anti-overflow cavity. During the operation of the cooking utensil, the flowing gas and liquid food will first enter the first anti-overflow cavity from the cooking cavity, and the liquid food and gas will be deposited and broken under the action of the inner wall of the first anti-overflow cavity, and then the gas and a small part of the liquid food will flow into the second anti-overflow cavity. Therefore, the blocking amount of the liquid food in the first anti-overflow cavity is greater than that in the second anti-overflow cavity. Further, setting the volume of the first anti-overflow cavity greater than that of the second anti-overflow cavity can increase the flow path of the liquid food in the first anti-overflow cavity, so as to improve the anti-overflow effect of the first anti-overflow cavity, and at the same time, it also prolongs the exhaust time of the cooking utensil, improves the cooking effect, and improves the overall cleanliness of the cooking utensil.

[0028] In some technical solutions of the utility model, optionally, the anti-overflow component also includes a grille, which is connected to the first body and is located in the first anti-overflow cavity. The grille divides the first anti-overflow cavity into a plurality of third anti-overflow cavities. The grille is provided with a third through hole, and the plurality of third anti-overflow cavities are connected through the third through hole.

[0029] In this technical solution, the anti-overflow component also includes a grille, which is connected to the first body and is located in the first anti-overflow cavity. The grille divides the first anti-overflow cavity into a plurality of third anti-overflow cavities, and the grille is provided with a third through hole, and the plurality of third anti-overflow cavities are connected through the third through hole. During the process of sudden pressure drop inside the cooking utensil, the liquid food material boils suddenly, and the food material and gas overflow, and enter the first anti-overflow cavity through the first through hole from the cooking cavity, and then the liquid food material and the food material that forms bubbles are blocked by setting the grille, and the bubble breaking and blocking effect is produced on the food material, so as to achieve anti-overflow. Part of the liquid food material and gas will enter the plurality of third anti-overflow cavities through the third through hole provided on the grille, so as to achieve the second blocking of the liquid food material, and at the same time, the gas is guided through the second through hole. Therefore, setting the grille to divide the first anti-overflow cavity to form a plurality of third anti-overflow cavities can prolong the exhaust time of the gas and accelerate the gas guiding rate of the gas, thereby improving the anti-overflow effect and the cooking effect.

[0030] In some technical solutions of the present invention, optionally, there are multiple first through holes, and the multiple first through holes are arranged side by side but do not reach the side wall of the first body.

[0031] In this technical solution, there are multiple first through holes, and the multiple first through holes are arranged in parallel so as not to reach the side wall of the first body. The multiple first through holes and the arrangement on the side wall of the first body can improve the contact between the first through holes and the overflowing gas and liquid food, thereby improving the anti-overflow effect, speeding up the exhaust flow of the cooking utensil, improving the cooking effect, and improving the overall cleanliness of the cooking utensil.

[0032] In some technical solutions of the present invention, optionally, the bottom wall of the first body includes a first area and a second area, the distance between the first area and the cover body is greater than the distance between the second area and the cover body; the bottom wall of the first body is provided with a fourth through hole, and the fourth through hole is located in the first area.

By providing two first bodies with height difference areas, the food on the first body can be diverted. When the food accumulates on the surface of the first body, the food in the second area will flow into the first area under the action of its own gravity, and then the liquid food can be refluxed through the fourth through hole provided on the first area, so as to avoid the overflowing food from accumulating in the first anti-overflow cavity after being blocked. While avoiding the accumulation of food, the air can be discharged smoothly, the air conduction rate can be accelerated, the cooking effect of the food can be improved, the food can be saved, and the difficulty of cleaning the cooking utensils can be reduced.

[0034] In some technical solutions of the present invention, optionally, the bottom wall of the first body is arranged to be inclined relative to the cover body from the second area to the first area; and the angle between the bottom wall of the first body and the cover body is greater than 10 degrees.

[0035] In this technical solution, the bottom wall of the first body is arranged to be inclined from the second area to the first area relative to the cover body; the angle between the bottom wall of the first body and the cover body is greater than 10 degrees. By setting the inclined bottom wall, the food can be quickly guided, the flow resistance of the food in the first anti-overflow cavity can be reduced, and the flow speed of the food from the second area to the first area can be increased. At the same time, when the food accumulates on the surface of the first body, the food in the second area will quickly flow into the first area under the action of the food's own gravity, which can avoid the accumulation of food and improve the smoothness of exhaust, speed up the air conduction rate, improve the cooking effect of the food, save food, and reduce the difficulty of cleaning the cooking utensils.

[0036] In some technical solutions of the present invention, optionally, the cover assembly further includes a one-way valve, which is disposed on the fourth through hole, and the liquid food in the first cavity can enter the cooking cavity through the one-way valve.

[0037] In this technical solution, the cover assembly further includes a one-way valve, which is disposed on the fourth through hole, and the liquid food in the first cavity can enter the cooking cavity through the one-way valve. The one-way valve can ensure smooth conduction from the first cavity to the cooking cavity, while blocking the liquid food in the cooking cavity from entering the first cavity, thereby ensuring smooth reflux of the blocked food in the first anti-overflow cavity, and preventing the liquid food in the cooking cavity from entering the anti-overflow cavity through the fourth through hole under the action of rising gas and pressure, thereby improving the anti-overflow effect.

[0038] In some technical solutions of the present utility model, optionally, the cross-sectional area of ​​the fourth through hole is greater than or equal to 12 square millimeters and less than or equal to 80 square millimeters.

[0039] In this technical solution, the cross-sectional area of ​​the fourth through hole is greater than or equal to 12 square millimeters and less than or equal to 80 square millimeters.

[0040] In some technical solutions of the present utility model, optionally, the minimum distance between the bottom wall of the first body and the maximum scale line of the cooking cavity is greater than or equal to 10 mm.

[0041] In this technical solution, the minimum distance between the bottom wall of the first body and the maximum scale line of the cooking cavity is greater than or equal to 10 mm. Since the volume of the food will change during the cooking process, by setting a readable range between the bottom wall of the first body and the maximum scale line of the cooking cavity, the influence of the first body on the volume of the cooking cavity can be avoided, thereby improving the reliability of the cooking appliance.

[0042] In some technical solutions of the present utility model, optionally, the anti-overflow component also includes a first rib, which is arranged on the side wall of the first body and protrudes from the side wall of the first body toward the outside of the first body.

At the same time, setting the ratio range of the sum of the cross-sectional areas of the first through holes to the area of ​​the side wall of the first body can enhance the first through hole's effect of destroying bubbles of liquid food and enhance the anti-overflow effect. The cross-sectional area of ​​the first through hole is greater than or equal to 0.5 square millimeters and less than or equal to 50 square millimeters, so that the first through hole can break the bubbles passing through the first through hole, so that the liquid food can fall back into the cooking cavity under the action of gravity, and the high-temperature and high-pressure gas can enter the cavity through the first through hole, and then be discharged from the cooking utensils through the exhaust component, while improving the anti-overflow effect of the anti-overflow component and improving the smoothness of the exhaust of the exhaust component. In addition, the cross-sectional area of ​​the first through hole is greater than or equal to 0.5 square millimeters and less than or equal to 50 square millimeters, which slows down the liquid outflow speed and improves the bubble breaking effect of the anti-overflow component. The cross-sectional area of ​​the first through hole is greater than or equal to 0.5 square millimeters and less than or equal to 50 square millimeters, which can also reduce the process difficulty of punching the first through hole, thereby reducing the processing cost of the anti-overflow component.

DETAILED DESCRIPTION

[0071] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0072] 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.

[0073] Refer to the following Figures 1 to 15A lid assembly 100 and a cooking appliance 200 according to some embodiments of the present invention are described.

[0074] In one embodiment of the present invention, a cover assembly 100 is provided. Figure 1 and Figure 2 As shown, the cover assembly 100 is used for a cooking utensil 200, which is provided with a cooking cavity 210. The cover assembly 100 includes a cover body 110 and an anti-overflow component 120. The anti-overflow component 120 is connected to the cover body 110 and is located on a side of the cover body 110 close to the cooking cavity 210; wherein, there is a gap between the edge of the anti-overflow component 120 on the side close to the cover body 110 and the cover body 110.

[0075] 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 210. The cover assembly 100 includes a cover body 110 and an anti-overflow component 120. The anti-overflow component 120 is connected to the cover body 110 and is located on a side of the cover body 110 close to the cooking cavity 210; wherein, there is a gap between the edge of the anti-overflow component 120 on the side close to the cover body 110 and the cover body 110. The cover assembly 100 can protect the cooking utensil 200. At the same time, when the cover assembly 100 is in the closed state, the cooking cavity 210 of the cooking utensil 200 can be pressurized. When the cooking utensil 200 is working, the temperature in the cooking cavity 210 rises. Since the cover assembly 100 seals the cooking cavity 210 through the cover body 110, the pressure in the cooking cavity 210 rises during the operation of the cooking utensil 200. The internal gas pressure of the cooking utensil 200 is greater than the external gas pressure. When the cooking utensil 200 is vented, the gas pressure in the cooking cavity 210 drops in a short time. Since the temperature of the food in the cooking cavity 210 drops slowly and the boiling point of the liquid decreases, the liquid food will boil in a short time. Then, the anti-overflow component 120 can be provided to prevent the sudden boiling of liquid food. The bubbles can be destroyed to achieve overflow prevention of the cooking utensil 200, and the probability of food bubbles overflowing from the cooking cavity 210 with the gas can be reduced. At the same time, during the exhaust process of the cooking utensil 200, the overflow prevention component 120 can also destroy the bubbles that float up under the action of pressure and flowing gas, and reduce the probability of liquid food overflowing. The allowable range of the heating power of the cooking utensil 200 can be increased by setting the overflow prevention component 120, and the continuous exhaust time of the cooking utensil 200 can be extended to improve the cooking effect of the food. The overall cleanliness of the cooking utensil 200 can also be improved, which is convenient for users to clean the cooking utensil 200 after cooking and improve the user experience of the cooking utensil 200. At the same time, the gap between the cover body 110 and the overflow prevention component 120 can further improve the overflow prevention effect of the cooking utensil 200.

[0076] Specifically, the anti-overflow component 120 and the cover body 110 may be an integrated structure or a split structure.

[0077] Specifically, the anti-overflow component 120 can be directly or indirectly fixed to the cover body 110, and the anti-overflow component 120 and the cover body 110 can be connected by providing a connecting piece.

[0078] Specifically, 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 this application.

[0079] 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.

[0080] 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.

[0084] 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.

[0085] like Figure 2 and Figure 3 As shown, the distance between the edge of the anti-overflow component 120 on the side close to the cover body 110 and the cover body 110 is less than or equal to 5 mm.

[0086] In this embodiment, the distance between the edge of the anti-overflow component 120 on the side close to the cover body 110 and the cover body 110 is less than or equal to 5 mm, thereby preventing some solid food from entering the anti-overflow component 120 under the action of air pressure and steam when the liquid food suddenly boils, preventing solid food from accumulating in the anti-overflow component 120, and reducing the probability of clogging of the anti-overflow component 120. By setting the size of the gap, further overflow prevention of the cooking utensil 200 can be achieved, and the anti-overflow effect can be improved. At the same time, it helps the anti-overflow component 120 to extend the continuous exhaust time of the cooking utensil 200, improve the cooking effect of the food, and also improve the overall cleanliness of the cooking utensil 200, making it easier for users to clean the anti-overflow component.

[0087] Specifically, if the gap between the cover 110 and the anti-overflow component 120 is greater than 5 mm, the anti-overflow effect of the anti-overflow component 120 will be affected. At the same time, when the cooking utensil 200 cooks liquid granular ingredients, a small part of the ingredients can be prevented from overflowing under the action of pressure and flowing gas, thereby improving the anti-overflow effect.

[0088] Specifically, Figure 2 As shown, the distance between the edge of the anti-overflow component 120 on the side close to the cover body 110 and the cover body 110 is H1, H1 is less than or equal to 5 mm, and H1 is greater than or equal to 1 mm.

[0090] 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.

[0091] like Figure 1 As shown, the cover assembly 100 also includes an exhaust assembly 130, which is arranged on the cover body 110; the anti-overflow component 120 includes a first body 122, which is connected to the cover body 110, and the first body 122 has a first cavity 1221 and a first through hole 1224, the first cavity 1221 is connected to the exhaust assembly 130, and the first cavity 1221 can be connected to the cooking cavity 210 through the first through hole 1224.

[0092] In this embodiment, the cover assembly 100 also includes an exhaust assembly 130, which is disposed on the cover body 110; the overflow prevention component 120 includes a first body 122, which is connected to the cover body 110, and the first body 122 has a first cavity 1221 and a first through hole 1224, and the first cavity 1221 is connected to the exhaust assembly 130, and the first cavity 1221 can be connected to the cooking cavity 210 through the first through hole 1224. When the cooking utensil 200 is exhausted, the gas in the cooking cavity 210 enters the first cavity 1221 through the first through hole 1224 under the effect of the pressure difference between the inside and outside of the cooking utensil, and then is guided by the exhaust component 130 connected to the first cavity 1221, thereby achieving the exhaust of the gas in the cooking utensil 200. The cooking utensil 200 guides the cooking cavity 210 by setting the exhaust component 130, adjusts the air pressure in the cooking cavity 210, and can also enrich the working mode of the cooking utensil 200 by adjusting the air pressure, improve the cooking effect, and also improve the taste of the food. The first body 122 can also destroy the bubbles formed by the liquid food, so that the food can be deposited in the cooking cavity 210 and the first anti-overflow part, and the bubbles of the food can be broken to reduce the probability of the bubbles formed by the food overflowing with the flowing gas, which can improve the overall cleanliness of the cooking utensil 200, facilitate the user to clean the cooking utensil 200 after cooking, and improve the user experience of the cooking utensil 200.

[0093] 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.

[0094] like Figure 4 and Figure 5 As shown, the first cavity 1221 includes a first anti-overflow cavity 1222 and a second anti-overflow cavity 1223 . The first anti-overflow cavity 1222 is connected to the first through hole 1224 ; the second anti-overflow cavity 1223 is connected to the first anti-overflow cavity 1222 , and the exhaust assembly 130 is opposite to the second anti-overflow cavity 1223 .

[0095] In this embodiment, the first cavity 1221 includes a first anti-overflow cavity 1222 and a second anti-overflow cavity 1223 .

When the cooking utensil 200 is working, bubbles and gas formed by the overflowing liquid food will pass through the first cavity 1221. Since the first anti-overflow cavity 1222 and the second anti-overflow cavity 1223 are provided in the first cavity 1221, the bubbles and gas formed by the food can be destroyed by the first through hole 1224 in the process of passing through the first anti-overflow portion, and the bubbles will also be destroyed when touching the inner wall of the anti-overflow cavity. The gas and part of the liquid food bubbles can enter the second anti-overflow cavity 1223. The second through hole 1262 of the second anti-overflow cavity 1223 further destroys the food bubbles, reducing the probability of the food bubbles overflowing with the discharged gas, thereby extending the exhaust channel of the cooking utensil 200, improving the efficiency of destroying the food bubbles, and at the same time improving the bubble breaking effect of the anti-overflow component 120.

[0096] 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.

[0097] like Figure 6 and Figure 7 As shown, the anti-overflow component 120 also includes a partition 124, which is connected to the first body 122 and is located in the first cavity 1221, dividing the first cavity 1221 into a first anti-overflow cavity 1222 and a second anti-overflow cavity 1223.

[0098] In this embodiment, the anti-overflow component 120 also includes a partition 124, which is connected to the first body 122 and is located in the first cavity 1221, and divides the first cavity 1221 into a first anti-overflow cavity 1222 and a second anti-overflow cavity 1223. When liquid food flows through the first cavity 1221, the partition 124 will destroy the food bubbles, thereby preventing the food from overflowing. At the same time, by setting the partition 124 to separate the first anti-overflow cavity 1222 and the second anti-overflow cavity 1223, the anti-overflow effect can be further improved, the exhaust time can be extended, and the cooking effect can be improved. The partition 124 can prevent solid food from overflowing, preventing the solid food from overflowing with the boiling liquid in the case of a sudden change in pressure, thereby improving the anti-overflow effect of the overall cooking utensil 200.

[0099] 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.

[0100] like Figure 1As shown, the overflow prevention component 120 also includes a second body 126, which is disposed in the first cavity 1221. The outer wall of the second body 126 and the inner wall of the first body 122 enclose a first overflow prevention cavity 1222, and the second body 126 has a second overflow prevention cavity 1223.

[0101] In this embodiment, the overflow prevention component 120 also includes a second body 126, and the second body 126 is arranged in the first cavity 1221. The outer wall of the second body 126 and the inner wall of the first body 122 enclose a first overflow prevention cavity 1222. The second body 126 has a second overflow prevention cavity 1223. The first overflow prevention cavity 1222 and the second overflow prevention cavity 1223 are separated by the second body 126. The second body 126 is arranged in the first body 122, which can further improve the overflow prevention effect, extend the exhaust time, and enhance the cooking effect.

[0102] Specifically, the second body 126 and the first body 122 may be an integrated structure or a split structure.

[0103] 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.

[0104] At least one second through hole 1262 is disposed on the side wall of the second body 126 , and the first anti-overflow cavity 1222 is connected to the second anti-overflow cavity 1223 through the at least one second through hole 1262 .

[0105] In this embodiment, the side wall of the second body 126 is provided with at least one second through hole 1262, and the first anti-overflow cavity 1222 is connected with the second anti-overflow cavity 1223 through the at least one second through hole 1262. The at least one second through hole 1262 can improve the flow of overflow gas into the second anti-overflow cavity 1223 through the first anti-overflow cavity 1222, improve the gas conduction efficiency, facilitate the exhaust of the cooking utensil 200, and improve the cooking effect of the cooking utensil 200.

[0106] Specifically, the number of the second through holes 1262 can be designed according to the working parameters of the cooking appliance 200 .

[0108] like Figure 4 As shown, the anti-overflow component 120 further includes a seal 140 , which is disposed between the first body 122 and the second body 126 .

[0109] In this embodiment, the anti-overflow component 120 also includes a seal 140, which is disposed between the first body 122 and the second body 126 to seal the gap between the first body 122 and the second body 126 to prevent food from remaining in the gap between the first body 122 and the second body 126 after the anti-overflow barrier, thereby improving the anti-overflow effect and facilitating the user to clean the cooking utensil 200.

[0110] Specifically, the seal 140 can be a silicone pad, and the silicone pad can be positioned by protrusions to facilitate the fixed installation of the second body 126 and the first body 122. The first body 122 and the second body 126 can be positioned by the silicone pad and then welded to ensure the consistency of the structure of the anti-overflow component 120 during assembly and installation.

[0111] Specifically, there may be a blind spot in cleaning in the gap between the first body 122 and the second body 126 of the overflow prevention component 120. The gap can be sealed by providing the seal 140 to avoid cleaning difficulties caused by the blind spot.

[0112] Specifically, the first body 122 and the second body 126 may be provided as a detachable structure for easy cleaning.

[0113] 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.

[0114] The volume of the first anti-overflow cavity 1222 is greater than the volume of the second anti-overflow cavity 1223 .

[0115] In this embodiment, the volume of the first anti-overflow cavity 1222 is greater than the volume of the second anti-overflow cavity 1223. During the operation of the cooking utensil 200, the flowing gas and liquid food will first enter the first anti-overflow cavity 1222 from the cooking cavity 210, and the liquid food and gas will be deposited and broken under the action of the inner wall of the first anti-overflow cavity 1222, and then the gas and a small part of the liquid food will flow into the second anti-overflow cavity 1223, so the blocking amount of the liquid food in the first anti-overflow cavity 1222 is greater than that of the second anti-overflow cavity 1223, and setting the volume of the first anti-overflow cavity 1222 greater than that of the second anti-overflow cavity 1223 can increase the flow path of the liquid food in the first anti-overflow cavity 1222, so as to improve the anti-overflow effect of the first anti-overflow cavity 1222, and at the same time, extend the exhaust time of the cooking utensil 200, improve the cooking effect, and improve the overall cleanliness of the cooking utensil 200.

[0116] 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.

[0117] like Fig.11 and Fig.12As shown, the anti-overflow component 120 also includes a grille 150, which is connected to the first body 122 and is located in the first anti-overflow cavity 1222. The grille 150 divides the first anti-overflow cavity 1222 into a plurality of third anti-overflow cavities 1228. The grille 150 is provided with a third through hole 1229, and the plurality of third anti-overflow cavities 1228 are connected through the third through hole 1229.

[0118] In this embodiment, the overflow prevention component 120 also includes a grille 150, which is connected to the first body 122 and is located in the first overflow prevention cavity 1222. The grille 150 divides the first overflow prevention cavity 1222 into a plurality of third overflow prevention cavities 1228. The grille 150 is provided with a third through hole 1229, and the plurality of third overflow prevention cavities 1228 are connected through the third through hole 1229. During the process of sudden pressure drop inside the cooking utensil 200, the liquid food boils suddenly, and the food and gas overflow, entering the first anti-overflow chamber 1222 from the cooking chamber 210 through the first through hole 1224, and then the liquid food and the food that forms bubbles are blocked by setting the grille 150, which has the effect of breaking bubbles and blocking the food, thereby preventing overflow. Some liquid food and gas will enter the multiple third anti-overflow chambers 1228 through the third through hole 1229 set on the grille 150, thereby blocking the liquid food again, and at the same time guiding the gas through the second through hole 1262. Therefore, setting the grille 150 to separate the first anti-overflow chamber 1222 to form multiple third anti-overflow chambers 1228 can extend the exhaust time of the gas and accelerate the gas guidance rate, thereby improving the cooking effect while improving the anti-overflow effect.

[0119] 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.

[0120] There are multiple first through holes 1224 , and the multiple first through holes 1224 are arranged side by side but do not reach the side wall of the first body 122 .

[0121] In this embodiment, there are multiple first through holes 1224, and the multiple first through holes 1224 are arranged side by side so as not to reach the side wall of the first body 122. The multiple first through holes 1224 and the arrangement on the side wall of the first body 122 can improve the contact between the first through holes 1224 and the overflowing gas and liquid food, thereby improving the anti-overflow effect, accelerating the exhaust flow of the cooking utensil 200, improving the cooking effect, and improving the overall neatness of the cooking utensil 200.

[0122] 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.

[0123] The bottom wall of the first body 122 includes a first area 1225 and a second area 1226 , and the distance between the first area 1225 and the cover body 110 is greater than the distance between the second area 1226 and the cover body 110 ; the bottom wall of the first body 122 is provided with a fourth through hole 1227 , and the fourth through hole 1227 is located in the first area 1225 .

By providing two first bodies 122 with height difference areas, the food on the first body 122 is guided. When the food accumulates on the surface of the first body 122, under the action of its own gravity, the food in the second area 1226 will flow into the first area 1225, and then the fourth through hole 1227 provided on the first area 1225 is used to realize the reflux of the liquid food, so as to prevent the overflow food from accumulating in the first anti-overflow cavity 1222 after being blocked, and to prevent the accumulation of food while improving the smoothness of exhaust, accelerating the air guiding rate, improving the cooking effect of food, saving food, and reducing the difficulty of cleaning the cooking utensil 200.

[0125] 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.

[0127] In this embodiment, the bottom wall of the first body 122 is arranged obliquely from the second area 1226 to the first area 1225 relative to the cover body 110; the angle between the bottom wall of the first body 122 and the cover body 110 is greater than 10 degrees. By setting the inclined bottom wall, the food can be quickly guided, the flow resistance of the food in the first anti-overflow cavity 1222 is reduced, and the flow speed of the food from the second area 1226 to the first area 1225 is increased. At the same time, when the food accumulates on the surface of the first body 122, under the action of the food's own gravity, the food in the second area 1226 will quickly flow into the first area 1225, avoiding the accumulation of food while improving the smoothness of exhaust, accelerating the air conduction rate, improving the cooking effect of the food, saving food, and reducing the difficulty of cleaning the cooking utensil 200.

[0128] Specifically, the included angle between the bottom wall of the first body 122 and the cover body 110 is α, α is greater than or equal to 10 degrees, and α is less than or equal to 30 degrees.

[0129] Specifically, α may be 10 degrees, α may be 15 degrees, α may be 20 degrees, α may be 25 degrees, and α may be 30 degrees.

[0130] 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.

[0132] In this embodiment, the cover assembly 100 further includes a one-way valve 160, which is disposed on the fourth through hole 1227, and the liquid food in the first cavity 1221 can enter the cooking cavity 210 through the one-way valve 160. The one-way valve 160 can ensure smooth conduction from the first cavity 1221 to the cooking cavity 210, and at the same time block the liquid food in the cooking cavity 210 from entering the first cavity 1221, thereby ensuring smooth backflow of the blocked food in the first anti-overflow cavity 1222, and preventing the liquid food in the cooking cavity 210 from entering the anti-overflow cavity through the fourth through hole 1227 under the action of rising gas and pressure, thereby improving the anti-overflow effect.

[0133] 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.

[0134] The cross-sectional area of ​​the fourth through hole 1227 is greater than or equal to 12 square millimeters and less than or equal to 80 square millimeters.

[0135] In this embodiment, the cross-sectional area of ​​the fourth through hole 1227 is greater than or equal to 12 square millimeters and less than or equal to 80 square millimeters. By setting the cross-sectional parameter range of the fourth through hole 1227, the smoothness of the liquid food backflow can be improved, the backflow efficiency can be improved, and the fourth through hole 1227 can be prevented from being blocked.

[0138] The minimum distance between the bottom wall of the first body 122 and the maximum scale line 180 of the cooking cavity 210 is greater than or equal to 10 mm.

[0139] In this embodiment, the minimum distance between the bottom wall of the first body 122 and the maximum scale line 180 of the cooking cavity 210 is greater than or equal to 10 mm. Since the volume of the food may change during the cooking process, by setting a readable range between the bottom wall of the first body 122 and the maximum scale line 180 of the cooking cavity 210, the influence of the first body 122 on the volume of the cooking cavity 210 can be avoided, thereby improving the reliability of the cooking device 200.

[0140] Specifically, when the cooking utensil 200 is cooking food, the food will expand. When the food is rice, the distance between the top of the rice in the cooking cavity 210 after cooking and the bottom wall of the first body 122 is set to be greater than or equal to 5 mm, thereby improving the anti-overflow effect while avoiding the influence of the anti-overflow component 120 on the cooked food.

[0141] Specifically, Fig.13 As shown, the minimum distance H4 between the bottom wall of the first body 122 and the maximum scale line 180 of the cooking cavity 210 is greater than or equal to 10 mm, and the minimum distance H4 between the bottom wall of the first body 122 and the maximum scale line 180 of the cooking cavity 210 is less than or equal to 30 mm.

[0143] Specifically, Fig.14 As shown, the maximum height line of the cooked rice is L1, and the distance between the bottom wall of the first body 122 and L1 is H2, and H2 should be greater than or equal to 5 mm and less than or equal to 25 mm.

[0144] Specifically, the distance H2 between the bottom wall of the first body 122 and L1 may be 5 mm, the distance H2 between the bottom wall of the first body 122 and L1 may be 10 mm, the distance H2 between the bottom wall of the first body 122 and L1 may be 15 mm, the distance H2 between the bottom wall of the first body 122 and L1 may be 20 mm, and the distance H2 between the bottom wall of the first body 122 and L1 may also be 25 mm.

[0145] 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.

[0146] like Figure 3 and Fig.10 As shown, the overflow prevention component 120 further includes a first rib 170 , which is disposed on the side wall of the first body 122 and protrudes from the side wall of the first body 122 toward the outside of the first body 122 .

[0147] In this embodiment, the overflow prevention component 120 further includes a first rib 170, which is disposed on the side wall of the first body 122 and protrudes outward from the side wall of the first body 122. The first rib 170 can prevent the overflow prevention component 120 from slipping.

[0148] 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.

[0149] There are multiple first through holes 1224, which are arranged in parallel; the ratio of the sum of the cross-sectional areas of the multiple first through holes 1224 to the area of ​​the side wall of the first body 122 is greater than or equal to 0.01% and less than or equal to 10%; and / or the ratio of the sum of the cross-sectional areas of the multiple first through holes 1224 to the surface area of ​​the first body 122 is greater than or equal to 0.01% and less than or equal to 20%; and / or the cross-sectional area of ​​the first through holes 1224 is greater than or equal to 0.5 square millimeters and less than or equal to 50 square millimeters.
