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, and the cooking utensil is provided with a cooking cavity. The cover assembly includes a cover body, a seal and an anti-overflow component; the seal is connected to the cover body and extends along the outer edge of the cover body; 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, and is located in the area enclosed by the inner edge of the seal, and the anti-overflow component covers at least a partial area of ​​the cover body.

[0007] The cover assembly provided in the present application can be covered on the cooking cavity of the cooking utensil, and then the cooking cavity can be sealed by the cover assembly. When the cover assembly seals the cooking cavity, the cooking cavity of the cooking utensil can be pressurized. 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 working process of the cooking utensil, and 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, by setting an anti-overflow component, the bubbles formed by the suddenly boiling liquid food can be destroyed, and the anti-overflow treatment of the cooking utensil can be achieved, reducing the probability of food bubbles overflowing the cooking cavity with the gas. Since the anti-overflow component can reduce the probability of food in the cooking cavity overflowing the cooking utensil, the allowable range of the heating power of the cooking utensil can be increased by setting the anti-overflow component, and the continuous exhaust time of the cooking utensil can be extended to improve the cooking effect of the food.

[0008] The cover assembly also includes a sealing member, which is connected to the cover body and extends along the outer edge of the cover body. The cover body can cooperate with the inner pot of the cooking utensil through the sealing member to achieve the sealing of the cooking cavity. The anti-overflow component is connected to the cover body and is located on the side of the cover body close to the cooking cavity and in the area surrounded by the inner edge of the sealing member. The anti-overflow component covers at least part of the cover body, which can increase the transverse size of the anti-overflow component, thereby increasing the volume of the anti-overflow cavity in the anti-overflow component without occupying too much space in the cooking cavity in the longitudinal direction, thereby improving the anti-overflow effect of the anti-overflow component.

[0009] Specifically, the anti-overflow component and the cover body may be an integrated structure or a split structure.

[0010] Specifically, the anti-overflow component can be fixed on the cover body directly or indirectly, and the anti-overflow component and the cover body can be connected by providing a connecting piece.

[0011] In addition, the cover assembly in the above technical solution provided by the utility model may also have the following additional technical features:

[0012] In some technical solutions of the utility model, optionally, the area of ​​the first region of the cover body covered by the overflow prevention component is the first area, the area of ​​the second region enclosed by the inner edge of the seal is the second area, and the ratio of the first area to the second area is greater than or equal to 90%.

[0013] In this embodiment, the area of ​​the first area of ​​the cover body covered by the overflow prevention component is the first area, and the area of ​​the second area enclosed by the inner edge of the seal is the second area. By adjusting the ratio of the first area to the second area, the volume of the overflow prevention cavity in the overflow prevention component is adjusted without occupying too much space in the cooking cavity in the longitudinal direction. And by setting the ratio of the first area to the second area to be greater than or equal to 90%, the area of ​​the cover body covered by the overflow prevention component is further increased, thereby increasing the volume of the overflow prevention cavity in the overflow prevention component and improving the overflow prevention effect of the overflow prevention component.

[0014] Furthermore, the ratio of the first area to the second area is less than or equal to 120%.

[0015] By setting the ratio of the first area to the second area to be less than or equal to 120%, the anti-overflow component is prevented from interfering with the cover of the cover assembly, thereby improving the sealing effect of the cover assembly on the cooking cavity.

[0016] Specifically, the ratio of the first area to the second area may be 90%.

[0017] The ratio of the first area to the second area may also be 93%.

[0018] The ratio of the first area to the second area may also be 95%.

[0019] The ratio of the first area to the second area may also be 100%.

[0020] The ratio of the first area to the second area may also be 110% or 120%.

[0021] In some technical schemes of the utility model, optionally, the cover assembly also includes an exhaust assembly, which is arranged on the cover body; the anti-overflow component includes a first body and a partition; the first body is connected to the cover body, and the first body has a cavity and a first through hole; the partition is arranged in the cavity and connected to the first body, and the partition divides the cavity into at least two anti-overflow cavities, and the at least two anti-overflow cavities include a first anti-overflow cavity and a second anti-overflow cavity, and the cooking cavity can be connected to the first anti-overflow cavity through the first through hole, and the first anti-overflow cavity is connected to the second anti-overflow cavity, and the second anti-overflow cavity is opposite to the exhaust assembly.

[0022] In this technical solution, the cover assembly also includes an exhaust assembly, which is arranged on the cover body. The cooking utensil guides air to the cooking cavity through the exhaust component, 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 the food.

[0023] The anti-overflow component includes a first body, which is connected to the cover body. The first body has a cavity and a first through hole. The cavity can be connected to the cooking cavity through the first through hole. When the cooking utensil is working, the gas in the cooking cavity enters the cavity through the first through hole under the action of pressure, and is then guided by the exhaust component connected to the 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 liquid food, so that the food can be deposited in the cooking cavity and the first body, and the bubbles of the food are broken to avoid food overflow, thereby improving the anti-overflow effect of the cooking utensil.

[0024] The overflow prevention component also includes a partition, which divides the cavity into at least two overflow prevention cavities, and the at least two overflow prevention cavities include a first overflow prevention cavity and a second overflow prevention cavity. The cooking cavity can be connected to the first overflow prevention cavity through a first through hole, and the first overflow prevention cavity is connected to the second overflow prevention cavity. The second overflow prevention cavity is opposite to the exhaust component. When the cooking utensil is exhausted through the exhaust component, the high-temperature and high-pressure gas in the cooking cavity can enter the first overflow prevention cavity through the first through hole, and then enter the second overflow prevention cavity from the first overflow prevention cavity. The second overflow prevention cavity is opposite to the exhaust component, and then the high-temperature and high-pressure gas in the second overflow prevention cavity is discharged from the cooking utensil through the exhaust component, thereby achieving exhaust of the cooking utensil. Since the high-temperature and high-pressure steam needs to pass through the first cooking cavity and the second cooking cavity in turn during the exhaust process of the cooking utensil, the path of the steam flowing inside the overflow prevention component is extended, further improving the overflow prevention effect of the overflow prevention component.

[0025] In some technical solutions of the present utility model, optionally, there is a first gap between the partition and the cover body, and the first anti-overflow cavity is connected with the second anti-overflow cavity through the first gap.

[0026] In this technical solution, there is a first gap between the partition and the cover body, and the first anti-overflow chamber is connected with the second anti-overflow chamber through the first gap. The high-temperature and high-pressure gas in the first anti-overflow chamber can enter the second anti-overflow chamber through the gap, and then the bubbles carried by the high-temperature and high-pressure gas can be broken through the gap between the partition and the cover body, thereby improving the smoothness of exhaust and the anti-overflow effect of the anti-overflow component.

[0027] Specifically, when the cooking appliance is venting, the food in the cooking cavity boils due to the venting, and a large number of bubbles are generated in the liquid in the cooking cavity, forming a gas-liquid coexistence state, which expands and flows toward the overflow prevention component. After the bubbles break through the first through hole, the volume of the gas-liquid coexistence state is reduced, and the liquid outflow speed is slowed down. When the first overflow prevention cavity is full, the liquid enters the second overflow prevention cavity through the gap formed by the partition and the pot cover, further slowing down the liquid outflow speed. Thus, the single exhaust time is increased.

[0028] In some technical solutions of the present utility model, optionally, a second through hole is provided on the partition, and the first anti-overflow cavity is connected with the second anti-overflow cavity through the second through hole.

[0029] In this technical solution, a second through hole is provided on the partition, and the first anti-overflow chamber is connected with the second anti-overflow chamber through the second through hole. The high-temperature and high-pressure gas in the first anti-overflow chamber can enter the second anti-overflow chamber through the second through hole, and then the bubbles carried by the high-temperature and high-pressure gas can be broken through the second through hole, thereby improving the exhaust smoothness and the anti-overflow effect of the anti-overflow component.

[0030] In some technical solutions of the present utility model, optionally, the first body has a third through hole, and the second anti-overflow cavity can be connected with the cooking cavity through the third through hole.

[0031] In this technical solution, the first body has a third through hole, and the second anti-overflow cavity can be connected to the cooking cavity through the third through hole, so that during the exhaust interval, the liquid food remaining in the second anti-overflow cavity can flow back into the cooking cavity through the third through hole, reducing the liquid food remaining in the second anti-overflow cavity, thereby reducing the waste of food. In addition, the liquid food remaining in the second anti-overflow cavity flows back into the cooking cavity through the third through hole, reducing the liquid food remaining in the second anti-overflow cavity, and reducing the difficulty of cleaning the anti-overflow cavity.

[0032] Furthermore, the bottom wall of the first body includes a first area and a second area, and 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 third through hole, and the third 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 third through hole provided on the first area, so that the overflowed food is prevented from accumulating in the first anti-overflow cavity after being blocked. While avoiding the accumulation of food, the air flow can be improved, 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.

[0033] Furthermore, the third through hole is arranged at the lowest point of the bottom wall of the first body.

[0034] Furthermore, the cover assembly further includes a one-way valve, which is disposed on the third through hole, and the liquid food in the second anti-overflow cavity can enter the cooking cavity through the one-way valve. The one-way valve can ensure smooth conduction from the second anti-overflow cavity to the cooking cavity, while blocking the liquid food in the cooking cavity from entering the second anti-overflow 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 third through hole under the action of rising gas and pressure, thereby improving the anti-overflow effect.

[0035] In some technical solutions of the present utility model, optionally, a cross-sectional area of ​​the first through hole in the first direction is greater than or equal to 0.5 square millimeters and less than or equal to 50 square millimeters.

[0036] In this technical solution, 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 utensil through the exhaust component, thereby reducing the speed of the liquid food overflowing the first through hole, 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.

[0037] Further, a cross-sectional area of ​​the first through hole in the first direction is greater than or equal to 10 square millimeters and less than or equal to 20 square millimeters.

[0038] Further, the cross-sectional area of ​​the first through hole may be 0.5 mm.

[0039] The cross-sectional area of ​​the first through hole may also be 1 mm.

[0040] The cross-sectional area of ​​the first through hole may also be 5 mm, 10 mm, 15 mm, 25 mm or 35 mm.

[0041] The cross-sectional area of ​​the first through hole may also be 50 mm.

[0042] In some technical solutions of the present invention, optionally, there are multiple first through holes, and the multiple first through holes are arranged in parallel; the ratio of the sum of the cross-sectional areas of the multiple first through holes in the first direction to the surface area of ​​the first body is greater than or equal to 0.01% and less than or equal to 10%.

[0043] In this technical solution, there are multiple first through holes, which are arranged in parallel. The ratio of the sum of the cross-sectional areas of the multiple first through holes in the first direction to the surface area of ​​the first body is greater than or equal to 0.01% and less than or equal to 10%. While ensuring the bubble breaking effect of the first through holes, the overall flow area of ​​the first through holes is increased, and while slowing down the speed at which liquid food overflows from the first through holes, the efficiency of high-temperature and high-pressure gas passing through the first through holes is improved, thereby improving the smoothness of exhaust of the cooking appliance.

[0044] Further, a ratio of a sum of cross-sectional areas of the plurality of first through holes in the first direction to a surface area of ​​the first body may be 0.01%.

[0045] The ratio of the sum of the cross-sectional areas of the plurality of first through holes in the first direction to the surface area of ​​the first body may also be 0.1%.

[0046] The ratio of the sum of the cross-sectional areas of the plurality of first through holes in the first direction to the surface area of ​​the first body may also be 1%, 2%, 3%, 5%, 7% and 8%.

[0047] The ratio of the sum of the cross-sectional areas of the plurality of first through holes in the first direction to the surface area of ​​the first body may also be 10%.

[0048] In some technical solutions of the present invention, optionally, the distance between the edge of the first body on one side close to the cover body and the cover body is less than or equal to 5 mm.

[0049] 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, thereby preventing some solid food from entering the anti-overflow component under the action of air pressure and steam when the liquid food suddenly boils, preventing solid food from accumulating in the anti-overflow component, and 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 food, and also improve the overall cleanliness of the cooking utensils, making it easier for users to clean the anti-overflow component.

[0050] Specifically, if the gap between the cover and the anti-overflow component is greater than 5 mm, the anti-overflow effect of the anti-overflow component will be affected. At the same time, when the cooking utensil 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.

[0051] Specifically, 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 and greater than or equal to 1 mm.

[0052] Specifically, it can be 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm.

Moreover, the elastic member clamps the overflow prevention member, making the disassembly and installation of the overflow prevention member more convenient, thereby reducing the difficulty of cleaning the overflow prevention member.

[0055] Furthermore, the elastic member may be a spring buckle, which may protrude from the side wall of the mounting component, and the clamping portion protrudes from the inner wall of the mounting tube. When the anti-overflow component is installed, the spring buckle can enter the mounting component under the action of the clamping portion, thereby enabling the sleeve to be inserted into the mounting component. After the clamping portion passes over the spring buckle, the spring buckle pops out, and the clamping portion clamps on the spring buckle, thereby achieving the installation of the anti-overflow component.

DETAILED DESCRIPTION

[0093] 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.

[0094] 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.

[0095] Refer to the following Figures 1 to 9 A lid assembly and a cooking appliance according to some embodiments of the present invention are described.

[0096] 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 210. The cover assembly 100 includes a cover body 110, a seal 170 and an anti-overflow component 120; the seal 170 is connected to the cover body 110 and extends along the outer edge of the cover body 110; 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, and is located in the area enclosed by the inner edge of the seal 170, and the anti-overflow component 120 covers at least a portion of the cover body 110.

[0097] In this embodiment, the cover assembly 100 can be covered on the cooking cavity 210 of the cooking device 200, and the cooking cavity 210 can be sealed by the cover assembly 100. When the cover assembly 100 seals the cooking cavity 210, the pressure of the cooking cavity 210 of the cooking device 200 can be maintained. When the cooking device 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 working process of the cooking device 200, and the internal gas pressure of the cooking device 200 is greater than the external gas pressure. When the cooking device 200 is venting, 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 is lowered, the liquid food will boil in a short time. Then, by setting the anti-overflow component 120, the bubbles formed by the suddenly boiling liquid food can be destroyed, so as to achieve the anti-overflow treatment of the cooking device 200 and reduce the probability of food bubbles overflowing the cooking cavity 210 with the gas. Since the anti-overflow component 120 can reduce the probability of food in the cooking cavity 210 overflowing the cooking device 200, the anti-overflow component 120 can also be set to increase the allowable range of the heating power of the cooking device 200, and at the same time extend the continuous exhaust time of the cooking device 200, thereby improving the cooking effect of the food.

[0098] The cover assembly 100 further includes a sealing member 170, which is connected to the cover body 110 and extends along the outer edge of the cover body 110. The cover body 110 can cooperate with the inner pot 230 of the cooking utensil 200 through the sealing member 170, thereby sealing the cooking cavity 210. 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, and is located in the area surrounded by the inner edge of the sealing member 170. The anti-overflow component 120 covers at least a part of the cover body 110, which can increase the transverse dimension of the anti-overflow component 120, thereby increasing the volume of the anti-overflow cavity in the anti-overflow component 120 without occupying too much space in the cooking cavity 210 in the longitudinal direction, thereby improving the anti-overflow effect of the anti-overflow component 120.

[0099] Specifically, the anti-overflow component 120 and the cover body 110 may be an integrated structure or a split structure.

[0100] 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.

[0101] 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.

[0107] 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.

[0108] like Figure 1 and Figure 3 As shown, the area of ​​the first area 162 of the cover body 110 covered by the overflow prevention component 120 is the first area, the area of ​​the second area 164 enclosed by the inner edge of the seal 170 is the second area, and the ratio of the first area to the second area is greater than or equal to 90%.

[0109] In this embodiment, the area of ​​the first region 162 of the cover body 110 covered by the overflow prevention component 120 is the first area, and the area of ​​the second region 164 enclosed by the inner edge of the sealing member 170 is the second area. By adjusting the ratio of the first area to the second area, the volume of the overflow prevention cavity in the overflow prevention component 120 is adjusted without occupying too much space in the cooking cavity 210 in the longitudinal direction. And by setting the ratio of the first area to the second area to be greater than or equal to 90%, the area of ​​the cover body 110 covered by the overflow prevention component 120 is further increased, thereby increasing the volume of the overflow prevention cavity in the overflow prevention component 120 and improving the overflow prevention effect of the overflow prevention component 120.

[0110] Furthermore, the ratio of the first area to the second area is less than or equal to 120%.

[0111] By setting the ratio of the first area to the second area to be less than or equal to 120%, the anti-overflow component 120 is prevented from interfering with the cover of the lid assembly 100, thereby improving the sealing effect of the lid assembly 100 on the cooking cavity 210.

[0112] Specifically, the ratio of the first area to the second area may be 90%.

[0113] The ratio of the first area to the second area may also be 93%.

[0114] The ratio of the first area to the second area may also be 95%.

[0115] The ratio of the first area to the second area may also be 100%.

[0116] The ratio of the first area to the second area may also be 110% or 120%.

[0117] Specifically, the area covered by the cover body 110 by the overflow prevention component 120 is the first area 162, that is, the area enclosed by the diameter D1 of the overflow prevention component 120 is the first area 162. The area enclosed by the inner edge of the seal 170 is the second area 164, that is, the area enclosed by the diameter D2 of the inner edge of the seal 170 is the second area 164.

[0118] The area S1 of the first region 162 = π(D1 / 2) 2 .

[0119] The area of ​​the second region 164 S2=π(D2 / 2) 2 .

[0120] The diameter D1 of the overflow prevention component 120 may be the diameter of the inner wall of the overflow prevention component 120 , or may be the diameter of the outer wall of the overflow prevention component 120 .

[0121] 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.

[0122] like Figure 1 and Figure 4As shown, the cover assembly 100 also includes an exhaust assembly 130, which is arranged on the cover body 110; the overflow prevention component 120 includes a first body 122 and a partition 124; the first body 122 is connected to the cover body 110, and the first body 122 has a cavity 1221 and a first through hole 1224; the partition 124 is arranged in the cavity 1221 and is connected to the first body 122, and the partition 124 separates the cavity 1221 into at least two overflow prevention cavities, and the at least two overflow prevention cavities include a first overflow prevention cavity 1222 and a second overflow prevention cavity 1223, and the cooking cavity 210 can be connected to the first overflow prevention cavity 1222 through the first through hole 1224, and the first overflow prevention cavity 1222 is connected to the second overflow prevention cavity 1223, and the second overflow prevention cavity 1223 is opposite to the exhaust assembly 130.

[0123] In this embodiment, the cover assembly 100 also includes an exhaust assembly 130, which is disposed on the cover body 110. The cooking utensil 200 guides air to the cooking cavity 210 through the exhaust component, adjusts the air pressure in the cooking cavity 210, 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.

[0124] The anti-overflow component 120 includes a first body 122, which is connected to the cover body 110. The first body 122 has a cavity 1221 and a first through hole 1224. The cavity 1221 can be connected to the cooking cavity 210 through the first through hole 1224. When the cooking utensil 200 is working, the gas in the cooking cavity 210 enters the cavity 1221 through the first through hole 1224 under the action of pressure, and is then guided by the exhaust component 130 connected to the cavity 1221, thereby realizing the discharge of the gas in the cooking utensil 200, adjusting the air pressure, and improving the cooking effect. At the same time, the first body 122 can also destroy the bubbles formed by liquid food, so that the food can be deposited in the cooking cavity 210 and the first body, and the bubbles of the food are broken to avoid food overflow, thereby improving the anti-overflow effect of the cooking utensil 200.

[0125] The overflow prevention component 120 also includes a partition 124, which divides the cavity 1221 into at least two overflow prevention cavities. The at least two overflow prevention cavities include a first overflow prevention cavity 1222 and a second overflow prevention cavity 1223. The cooking cavity 210 can be connected to the first overflow prevention cavity 1222 through the first through hole 1224, and the first overflow prevention cavity 1222 is connected to the second overflow prevention cavity 1223. The second overflow prevention cavity 1223 is opposite to the exhaust component 130. When the cooking utensil 200 is exhausted through the exhaust component 130, the high-temperature and high-pressure gas in the cooking cavity 210 can enter the first overflow prevention cavity 1222 through the first through hole 1224, and then enter the second overflow prevention cavity 1223 from the first overflow prevention cavity 1222. The second overflow prevention cavity 1223 is opposite to the exhaust component 130, and then the high-temperature and high-pressure gas in the second overflow prevention cavity 1223 is discharged from the cooking utensil 200 through the exhaust component 130, thereby achieving exhaust of the cooking utensil 200. Since the high-temperature and high-pressure steam of the cooking appliance 200 needs to pass through the first cooking cavity 210 and the second cooking cavity 210 in turn during the exhaust process, the flow path of the steam inside the anti-overflow component 120 is extended, further improving the anti-overflow effect of the anti-overflow component 120.

[0126] Specifically, the first through hole 1224 may be a circular hole, a triangular hole, or a polygonal hole, or a through hole of any shape.

[0127] 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.

[0128] like Figure 1 As shown, there is a first gap 1242 between the partition 124 and the cover body 110 , and the first anti-overflow cavity 1222 is connected to the second anti-overflow cavity 1223 through the first gap 1242 .

[0129] In this embodiment, there is a first gap 1242 between the partition 124 and the cover body 110, and the first anti-overflow chamber 1222 is connected to the second anti-overflow chamber 1223 through the first gap 1242. The high-temperature and high-pressure gas in the first anti-overflow chamber 1222 can enter the second anti-overflow chamber 1223 through the gap, and then the bubbles carried by the high-temperature and high-pressure gas can be broken through the gap between the partition 124 and the cover body 110, thereby improving the smoothness of exhaust and the anti-overflow effect of the anti-overflow component 120.

[0130] Specifically, when the cooking device 200 is venting, the food in the cooking cavity 210 boils due to the venting, and a large number of bubbles are generated in the liquid in the cooking cavity 210, forming a gas-liquid coexistence state, and the volume expands and flows toward the overflow prevention component 120, wherein the bubbles break after passing through the first through hole 1224, reducing the volume of the gas-liquid coexistence state, slowing down the liquid outflow speed, and when the first overflow prevention cavity 1222 is full, the liquid enters the second overflow prevention cavity 1223 through the gap formed by the partition 124 and the pot cover, further slowing down the liquid outflow speed, thereby increasing the single exhaust time.

[0131] A height A of the first gap 1242 is less than or equal to 5 mm.

[0132] 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.

[0133] like Figure 5 As shown, a second through hole 1244 is provided on the partition 124 , and the first anti-overflow cavity 1222 is connected with the second anti-overflow cavity 1223 through the second through hole 1244 .

[0134] In this embodiment, a second through hole 1244 is provided on the partition 124, and the first anti-overflow chamber 1222 is connected with the second anti-overflow chamber 1223 through the second through hole 1244. The high-temperature and high-pressure gas in the first anti-overflow chamber 1222 can enter the second anti-overflow chamber 1223 through the second through hole 1244, and then the bubbles carried by the high-temperature and high-pressure gas can be broken through the second through hole 1244, thereby improving the exhaust smoothness and the anti-overflow effect of the anti-overflow component 120.

[0135] 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.

[0136] like Figure 4 and Figure 5 As shown, the first body 122 has a third through hole 1229 , and the second anti-overflow cavity 1223 can be connected to the cooking cavity 210 through the third through hole 1229 .

[0137] In this embodiment, the first body 122 has a third through hole 1229, and the second anti-overflow cavity 1223 can be connected to the cooking cavity 210 through the third through hole 1229, so that during the exhaust interval, the liquid food remaining in the second anti-overflow cavity 1223 can flow back into the cooking cavity 210 through the third through hole 1229, reducing the liquid food remaining in the second anti-overflow cavity 1223, thereby reducing the waste of food. In addition, the liquid food remaining in the second anti-overflow cavity 1223 flows back into the cooking cavity 210 through the third through hole 1229, reducing the liquid food remaining in the second anti-overflow cavity 1223, and reducing the difficulty of cleaning the anti-overflow cavity.

[0138] Further, the bottom wall of the first body 122 includes a first area 162 and a second area 164, and the distance between the first area 162 and the cover 110 is greater than the distance between the second area 164 and the cover 110; the bottom wall of the first body 122 is provided with a third through hole 1229, and the third through hole 1229 is located in the first area 162. By providing two first bodies 122 with height difference areas, the food on the first body 122 can be diverted. When the food accumulates on the surface of the first body 122, the food in the second area 164 will flow into the first area 162 under the action of its own gravity, and then the third through hole 1229 provided on the first area 162 can be used to realize the reflux of the liquid food, so as to prevent the overflowed 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 gas conduction rate, improving the cooking effect of food, saving food, and reducing the difficulty of cleaning the cooking utensil 200.

[0139] Furthermore, the third through hole 1229 is disposed at the lowest point of the bottom wall of the first body 122 .

[0140] Furthermore, the cover assembly 100 further includes a one-way valve, which is disposed on the third through hole 1229, and the liquid food in the second anti-overflow cavity 1223 can enter the cooking cavity 210 through the one-way valve. The one-way valve can ensure smooth conduction from the second anti-overflow cavity 1223 to the cooking cavity 210, and at the same time block the liquid food in the cooking cavity 210 from entering the second anti-overflow cavity 1223, thereby ensuring smooth reflux 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 third through hole 1229 under the action of rising gas and pressure, thereby improving the anti-overflow effect.

[0141] 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.

[0142] An area of ​​a cross section of the first through hole 1224 in the first direction is greater than or equal to 0.5 square millimeters and less than or equal to 50 square millimeters.

[0143] In this embodiment, the cross-sectional area of ​​the first through hole 1224 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 1224 can break the bubbles passing through the first through hole 1224, so that the liquid food can fall back into the cooking cavity 210 under the action of gravity, and the high-temperature and high-pressure gas can enter the cavity 1221 through the first through hole 1224, and then be discharged from the cooking utensil 200 through the exhaust component 130, while slowing down the speed of the liquid food overflowing the first through hole 1224, improving the anti-overflow effect of the overflow prevention component 120, and improving the smoothness of the exhaust of the exhaust component 130. In addition, the cross-sectional area of ​​the first through hole 1224 is greater than or equal to 0.5 square millimeters and less than or equal to 50 square millimeters, slowing down the liquid outflow speed, and thus improving the bubble breaking effect of the overflow prevention component 120. The cross-sectional area of ​​the first through hole 1224 is greater than or equal to 0.5 square millimeters and less than or equal to 50 square millimeters, which can also reduce the difficulty of punching the first through hole 1224 and further reduce the processing cost of the anti-overflow component 120 .

[0144] Further, the cross-sectional area of ​​the first through hole 1224 in the first direction is greater than or equal to 10 square millimeters and less than or equal to 20 square millimeters.

[0145] Furthermore, the cross-sectional area of ​​the first through hole 1224 may be 0.5 mm.

[0146] The cross-sectional area of ​​the first through hole 1224 may also be 1 mm.

[0147] The cross-sectional area of ​​the first through hole 1224 may also be 5 mm, 10 mm, 15 mm, 25 mm or 35 mm.

[0148] The cross-sectional area of ​​the first through hole 1224 may also be 50 mm.

[0149] Specifically, the flow direction of the liquid food when passing through the first through hole 1224 is the second direction, and the first direction is perpendicular to the second direction.

[0150] 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.

[0151] like Figure 4 and Figure 5 As shown, 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 in the first direction to the surface area of ​​the first body 122 is greater than or equal to 0.01% and less than or equal to 10%.

[0152] In this embodiment, 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 in the first direction to the surface area of ​​the first body 122 is greater than or equal to 0.01% and less than or equal to 10%. While ensuring the bubble breaking effect of the first through holes 1224, the overall flow area of ​​the first through holes 1224 is increased, and while slowing down the speed at which liquid food overflows from the first through holes, the efficiency of high-temperature and high-pressure gas passing through the first through holes 1224 is improved, thereby improving the smoothness of exhaust of the cooking appliance 200.

[0153] Further, the ratio of the sum of the cross-sectional areas of the plurality of first through holes 1224 in the first direction to the surface area of ​​the first body 122 may be 0.01%.

[0154] The ratio of the sum of the cross-sectional areas of the plurality of first through holes 1224 in the first direction to the surface area of ​​the first body 122 may also be 0.1%.

[0155] The ratio of the sum of the cross-sectional areas of the plurality of first through holes 1224 in the first direction to the surface area of ​​the first body 122 may also be 1%, 2%, 3%, 5%, 7% and 8%.

[0156] The ratio of the sum of the cross-sectional areas of the plurality of first through holes 1224 in the first direction to the surface area of ​​the first body 122 may also be 10%.

[0157] 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.

[0158] like Figure 1 As shown, a distance B between an edge of the first body 122 on one side close to the cover body 110 and the cover body 110 is less than or equal to 5 mm.

[0159] In this embodiment, the distance B between the edge of the anti-overflow component 120 on one 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 anti-overflow 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 120.

[0160] 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.

[0161] Specifically, 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 and greater than or equal to 1 mm.

[0162] Specifically, the distance between the edge of the anti-overflow component 120 on one side close to the cover body 110 and the cover body 110 can be 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm.

[0163] 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.

[0165] In this embodiment, the elastic member 150 is connected to the mounting member 140 and protrudes from the side wall of the mounting member 140. The mounting tube 128 is sleeved on the mounting member 140. The inner wall of the mounting tube 128 is provided with a clamping portion 129 protruding toward the inside of the mounting tube 128. The clamping portion 129 is clamped to the elastic member 150, thereby realizing the installation and positioning of the overflow prevention member 120. In addition, the elastic member 150 is clamped to the overflow prevention member 120, so that the disassembly and installation of the overflow prevention member 120 is more convenient, thereby reducing the difficulty of cleaning the overflow prevention member 120.

[0166] Furthermore, the elastic member 150 may be a spring buckle, which may protrude from the side wall of the mounting component 140, and the clamping portion 129 protrudes from the inner wall of the mounting tube 128. When the anti-overflow component 120 is installed, the spring buckle can enter the mounting component 140 under the action of the clamping portion 129, thereby allowing the sleeve to be inserted into the mounting component 140. After the clamping portion 129 passes over the spring buckle, the spring buckle pops out, and the clamping portion 129 is clamped on the spring buckle, thereby achieving the installation of the anti-overflow component 120.

[0167] 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.

[0168] like Figure 6 As shown, the mounting component 140 is provided with a mounting cavity 142, and the opening of the mounting cavity 142 faces the cooking cavity. The cover assembly 100 also includes a temperature detection component 180, and the temperature detection component 180 is arranged in the mounting cavity 142. The detection end of the temperature detection component 180 is opposite to the opening of the mounting cavity 142, and can detect the temperature in the cooking cavity.

[0169] In this technical solution, the opening of the installation cavity 142 faces the cooking cavity, and the temperature detection component 180 is arranged in the installation cavity 142. The detection end of the temperature detection component 180 is opposite to the opening of the installation cavity 142, so that the temperature detection component 180 can more directly contact the steam in the cooking cavity, thereby making the temperature detection component 180 more accurate in detecting the temperature in the cooking cavity.

[0170] Further, the temperature detection component 180 is a temperature sensor.

[0171] 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.

[0172] like Figure 6 As shown, the mounting component 140 and the temperature sensing component 180 are closer to the center of the cover body 110 than to the edge of the cover body 110 and the center of the cover body 110 .

[0173] In this technical solution, the mounting component 140 and the temperature detection component 180 are closer to the center of the cover 110 relative to the edge of the cover 110 and the center of the cover 110, thereby making the installation of the anti-overflow component 120 and the temperature detection component 180 more stable, and improving the reliability of the mounting component 140 and the temperature detection component 180 during the operation of the cooking appliance. Compared with the edge of the cover 110 and the center of the cover 110, the temperature detection component 180 is closer to the center of the cover 110, so that the temperature detection component 180 can detect the temperature of the central area of ​​the cooking cavity, further improving the detection accuracy of the temperature detection component 180.

[0174] 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.

[0175] The mounting component 140 is located in the first anti-overflow cavity 1222 , and the temperature detection component 180 is opposite to the first through hole 1224 .

[0176] In this technical solution, the installation component 140 is located in the first anti-overflow cavity 1222, and the temperature detection component 180 is opposite to the first through hole 1224. The steam in the cooking cavity can enter the anti-overflow component 120 through the first through hole 1224, so that the temperature of the steam contacted by the temperature detection component 180 is closer to the temperature of the steam in the cooking cavity, thereby further improving the accuracy of the temperature detection component 180 in detecting the temperature in the cooking cavity.

[0177] 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.

[0178] The anti-overflow component 120 is clamped on one end of the exhaust component 130 close to the cooking cavity, and the air inlet of the exhaust component 130 is located in the second anti-overflow cavity 1223.
