Description

Technical Field

[0001] This invention relates to the field of cooking equipment technology, specifically to exhaust assemblies, cover assemblies, and cooking equipment. Background Technology

[0002] Micro-pressure cooking devices, such as micro-pressure rice cookers, typically have a ball valve assembly at the steam outlet. The ball valve assembly includes a steel ball and a steel ball seat. The steel ball seat has an airflow channel inside, and the steel ball is placed on the steel ball seat. The steel ball itself can movably block the steam outlet of the airflow channel. When the pressure inside the rice cooker exceeds a certain level, it will push open the steel ball to release the pressure. When the pressure drops to a certain level, the steel ball will block the steam outlet again, thus creating a micro-pressure environment inside the rice cooker.

[0003] In related technologies, the steel ball base is connected to an anti-clogging cover, which has an air inlet connected to the airflow channel of the steel ball base. The air inlet is a small hole or a cross-shaped groove. Due to its small area, ingredients such as rice paste, rice grains, mung beans, mixed grains, and seaweed can easily clog the air inlet during cooking, causing the pressure inside the pot to continuously increase and creating a serious safety hazard. Because of the small area of ​​the air inlet, the air pressure above the pot is high during cooking. When the lid is closed, the gas escapes inefficiently from the lid's exhaust channel to the outside, resulting in high pressure when the lid is closed while hot. Summary of the Invention

[0004] In view of this, the present invention provides an exhaust assembly, a cover assembly, and a cooking device to solve the problem that the air inlet on the anti-clogging cover of related technologies is easily blocked, resulting in increased pressure inside the pot.

[0005] In a first aspect, the present invention provides an exhaust assembly, comprising: The ball seat has an internal airflow channel, and the side wall of the ball seat has a first air inlet that communicates with the airflow channel; An anti-clogging cover is connected to the ball seat. The anti-clogging cover includes a main body portion located at the end of the ball seat and a connecting portion surrounding the ball seat. The main body portion is provided with a second air inlet communicating with the airflow channel, and the first air inlet is higher than the connecting portion.

[0006] Beneficial effects: By setting a first air inlet on the side wall of the ball-shaped base and a second air inlet in the main body of the anti-clogging cover, the steam generated during cooking can enter the airflow channel of the ball-shaped base through both the first and second air inlets. This increases the exhaust area and improves exhaust capacity. Even if the second air inlet is blocked, exhaust can still be achieved through it, eliminating the serious safety hazard caused by the continuous increase in pressure inside the pot when the second air inlet is blocked. Simultaneously, because the first air inlet is higher than the connecting part, the airflow path inside the pot is initially upward, then turns, entering the airflow channel inside the ball-shaped base through the first air inlet. This complex airflow path reduces the risk of food such as rice paste, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet.

[0007] In one alternative embodiment, the first air inlet includes at least one strip-shaped hole extending circumferentially along the ball seat.

[0008] Beneficial effects: The first air inlet includes at least one strip-shaped hole extending circumferentially along the ball seat. The length of the strip-shaped hole is relatively large, thereby reducing the risk of food such as rice milk, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet.

[0009] In one optional implementation, the height of the first air inlet is A1, where 0.5 mm ≤ A1 ≤ 3 mm; And / or, the length of the first air inlet is A2, 5 mm ≤ A2 ≤ 50 mm.

[0010] Beneficial effects: The height of the first air inlet is between 0.5mm and 3mm, which can intercept most of the food ingredients, preventing them from entering and clogging the first air inlet. If the height of the first air inlet is less than 0.5mm, processing becomes more difficult and exhaust efficiency is low; if the height of the first air inlet is greater than 3mm, it loses its function of intercepting food ingredients. The length of the first air inlet is between 5mm and 50mm. A longer first air inlet reduces the risk of food ingredients such as rice paste, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet. If the length of the first air inlet is less than 5mm, food ingredients can easily clog it completely; if the length of the first air inlet is greater than 50mm, the anti-clogging insert will be too large, resulting in a disproportionate size compared to other parts of the cover assembly.

[0011] In one optional embodiment, the ball seat includes a ball seat body and an anti-clogging insert connected as one piece. The ball seat body is made of plastic, the anti-clogging insert is made of metal, the anti-clogging cover is made of metal, and the anti-clogging cover is detachably connected to the anti-clogging insert.

[0012] Beneficial effects: Since the anti-clogging insert and the anti-clogging cover are both made of metal, and the anti-clogging cover and the anti-clogging insert are detachably connected, no powder will fall off during the assembly and disassembly of the anti-clogging insert and the anti-clogging cover.

[0013] In one alternative embodiment, the anti-clogging insert is injection molded integrally with the ball seat body.

[0014] Beneficial effects: The anti-blocking insert is injection molded into the ball seat body. Under the premise that the anti-blocking insert is a metal part, the anti-blocking insert and the ball seat body are connected into one piece, reducing the number of parts, reducing assembly steps, and there is no gap between the anti-blocking insert and the ball seat body.

[0015] In one optional embodiment, the ball seat body is provided with a first buckle, and the anti-blocking insert is provided with a second buckle, the second buckle cooperating with the first buckle.

[0016] Beneficial effects: The ball seat body has a first inverted buckle, and the anti-blocking insert has a second inverted buckle. The second inverted buckle cooperates with the first inverted buckle. After injection molding, the ball seat body and the anti-blocking insert cannot be disassembled, which can ensure the stability of the ball seat body and the anti-blocking insert being connected as one.

[0017] In one optional embodiment, the second air inlet includes a plurality of through holes arranged radially. The diameter of the through hole is D, 0.5 mm ≤ D ≤ 3 mm; and / or, the total area of ​​the plurality of through holes is > 30 mm. 2 .

[0018] Beneficial effects: The second air intake includes multiple radially arranged through holes, with a sufficient number of through holes and a total area of ​​more than 30 mm. 2 This effectively reduces the chance of rice paste, rice grains, mung beans, mixed grains, seaweed, and other ingredients completely clogging the air vents during cooking. The vent diameter is D, 0.5mm ≤ D ≤ 3mm. The vents can intercept most of the mixed grains, preventing them from entering the airflow channel.

[0019] Secondly, the present invention also provides a cover assembly, comprising: Insulated cover plate; The exhaust assembly, wherein the ball seat is sealed to the insulation cover plate.

[0020] Beneficial effects: This lid assembly, with a first air inlet on the side wall of the ball seat and a second air inlet in the main body of the anti-clogging cover, allows steam generated during cooking to enter the airflow channel of the ball seat through both inlets. This increases the exhaust area and improves exhaust capacity. Even if the second air inlet is blocked, steam can still escape through it, preventing the serious safety hazard caused by a continuous increase in pressure inside the pot when the second air inlet is blocked. Furthermore, because the first air inlet is higher than the connecting part, the airflow path inside the pot is initially upward, then bends, entering the airflow channel inside the ball seat through the first air inlet. This complex airflow path reduces the risk of food such as rice paste, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet. The ball seat and the heat-insulating cover are sealed together, preventing steam generated during cooking from entering the lid assembly through gaps between them.

[0021] In one optional embodiment, the heat-insulating cover plate includes a main body and a protrusion, the protrusion protruding in a direction away from the inner cavity of the pot, the protrusion being annular, and the inner side of the protrusion being sealed to the ball seat by a sealing ring.

[0022] Beneficial effects: The heat-insulating cover includes a main body and a protruding part. The protruding part protrudes in a direction away from the inner cavity of the pot. The protruding part is annular. The inner side of the protruding part is sealed to the ball seat by a sealing ring. Therefore, it can save the space occupied by the anti-clogging cover and the ball seat in the inner cavity of the pot, increase the height of the anti-clogging cover, and increase the difficulty of food overflowing into the second air inlet of the anti-clogging cover and the first air inlet of the ball seat. This can reduce the risk of the second air inlet and the first air inlet being blocked by food.

[0023] In one optional embodiment, the height of the protrusion protruding from the main body is A3, where 2 mm ≤ A3 ≤ 15 mm.

[0024] Beneficial effects: The height of the protrusion from the main body is A3, 2mm≤A3≤15mm, which can save the space occupied by the anti-blocking cover and the ball seat in the inner cavity of the pot. Increasing the height of the anti-blocking cover increases the difficulty of food overflowing into the second air inlet of the anti-blocking cover and the first air inlet of the ball seat, which can reduce the risk of the second air inlet and the first air inlet being blocked by food.

[0025] In one alternative embodiment, the top of the connecting portion is higher than the main body portion.

[0026] Beneficial effects: Since the top of the connecting part is higher than the main body, the airflow path inside the pot is first upward, enters the space inside the protrusion, then turns, and enters the airflow channel inside the ball seat through the first air inlet. The complex airflow path inside the pot reduces the risk of food such as rice milk, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet.

[0027] In one alternative embodiment, the top of the connecting portion includes an annular first plane and a second plane, the second plane being located inside the first plane and lower than the first plane.

[0028] Beneficial effects: The top of the connecting part includes a ring-shaped first plane and a second plane. The second plane is located inside the first plane and is lower than the first plane. The first plane is equivalent to adding baffles around the anti-blocking cover. The airflow enters the first air inlet by rising to a certain height and then turning. The path is complex, which further improves the anti-blocking effect.

[0029] In one alternative implementation, the height of the first plane above the second plane is A4, where 0.5 mm ≤ A4 ≤ 3 mm.

[0030] In one alternative implementation, the top of the first air inlet is lower than the sealing ring.

[0031] Beneficial effect: The top of the first air inlet is lower than the sealing ring, which can ensure that the airflow can smoothly enter the first air inlet.

[0032] Thirdly, the present invention also provides a cooking device including the aforementioned cover assembly.

[0033] Beneficial effects: This cooking device, by setting a first air inlet on the side wall of the ball base and a second air inlet in the main body of the anti-clogging cover, allows steam generated during cooking to enter the airflow channel of the ball base through both inlets. This increases the exhaust area and improves exhaust capacity. Even if the second air inlet is blocked, exhaust can still be achieved through it, eliminating the serious safety hazard caused by the continuous increase in pressure inside the pot when the second air inlet is blocked. Furthermore, because the first air inlet is higher than the connecting part, the airflow path inside the pot is initially upward, then turns, entering the airflow channel inside the ball base through the first air inlet. This complex airflow path reduces the risk of food such as rice paste, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Micro-pressure cooking devices, such as micro-pressure rice cookers, typically have a ball valve assembly at the steam outlet. The ball valve assembly includes a steel ball and a steel ball seat 1'. The steel ball seat 1' has an airflow channel inside, and the steel ball is placed on the steel ball seat 1'. The steel ball itself can movably block the steam outlet of the airflow channel. When the pressure inside the rice cooker exceeds a certain level, it will push open the steel ball to release the pressure. When the pressure drops to a certain level, the steel ball will block the steam outlet again, thus creating a micro-pressure environment inside the rice cooker.

[0042] In related technologies, a steel ball seat 1′ is connected to an anti-clogging cover 2′, and the anti-clogging cover 2′ is provided with an air inlet 201′, which is connected to the airflow channel of the steel ball seat 1′, such as... Figure 1 As shown, the air inlet 201' is a small hole or cross-shaped groove. Due to its small area, ingredients such as rice paste, rice grains, mung beans, mixed grains, and seaweed can easily clog the air inlet during cooking, causing the pressure inside the pot to continuously increase and creating a serious safety hazard. Because the air inlet 201' is small, the pressure above the pot is high during cooking. When the lid is closed, the gas escapes inefficiently from the lid's venting channel to the outside, resulting in high pressure when the lid is closed while hot.

[0043] In addition, such as Figure 2 As shown, in the related technology, the steel ball seat 1′ is a plastic part and the anti-clogging cover 2′ is a metal part, and the two are connected by threads, which facilitates the disassembly and cleaning of the anti-clogging cover 2′. However, during the disassembly and assembly of the anti-clogging cover 2′, the plastic part will shed powder due to friction, resulting in a poor user experience.

[0044] The following is combined Figures 3 to 8 The following describes embodiments of the present invention.

[0045] According to an embodiment of the present invention, in a first aspect, an exhaust assembly is provided, including a ball seat 1 and an anti-clogging cover 2.

[0046] The ball seat 1 has an airflow channel inside, and the side wall of the ball seat 1 has a first air inlet 1021 that communicates with the airflow channel. The anti-blocking cover 2 is connected to the ball seat 1. The anti-blocking cover 2 includes a main body 201 located at the end of the ball seat 1 and a connecting part 202 surrounding the ball seat 1. The main body 201 has a second air inlet 2011 that communicates with the airflow channel, and the first air inlet 1021 is higher than the connecting part 202.

[0047] In this embodiment, a first air inlet 1021 is provided on the side wall of the ball seat 1, and a second air inlet 2011 is provided on the main body 201 of the anti-clogging cover 2. Specifically, during the cooking process, the generated steam can enter the airflow channel of the ball seat 1 through the first air inlet 1021 and the second air inlet 2011, increasing the exhaust area and improving exhaust capacity. When the second air inlet 2011 is blocked, exhaust can still be achieved through the second air inlet 2011, preventing the serious safety hazard caused by the continuous increase in pressure inside the pot when the second air inlet 2011 is blocked. At the same time, since the first air inlet 1021 is higher than the connecting part 202, the airflow path inside the pot is upward first, then turns, and enters the airflow channel inside the ball seat 1 through the first air inlet 1021. The complex airflow path inside the pot reduces the risk of food such as rice paste, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet 1021.

[0048] In one embodiment, the first air inlet 1021 includes at least one strip-shaped hole extending circumferentially along the ball seat 1.

[0049] In this embodiment, the first air inlet 1021 includes at least one strip-shaped hole extending circumferentially along the ball seat 1. The length of the strip-shaped hole is relatively large, thereby reducing the risk of food such as rice milk, rice grains, mung beans, mixed grains, seaweed, etc. clogging the first air inlet 1021.

[0050] In one specific embodiment, the first air inlet 1021 includes a plurality of strip-shaped holes extending circumferentially along the ball seat 1.

[0051] In one specific embodiment, the ball seat 1 includes a ball seat body 101 and an anti-blocking insert 102 integrally connected. The air outlet of the airflow channel is located in the ball seat body 101, and the first air inlet 1021 is located in the anti-blocking insert 102. Figure 5 and Figure 7 As shown, the anti-blocking insert 102 has a cylindrical cavity inside, which forms part of the airflow channel, and the strip hole is arc-shaped.

[0052] Specifically in one embodiment, such as Figure 8As shown, there are three first air inlets 1021. Two adjacent first air inlets 1021 are separated by a spacer block 1023. The spacer block 1023 is trapezoidal. The length of the inner end of the spacer block 1023 is greater than the length of the outer end of the spacer block 1023. Therefore, the length of the outer end of the first air inlet 1021 is greater than the length of the inner end of the first air inlet 1021.

[0053] In one embodiment, the height of the first air inlet 1021 is A1, 0.5 mm ≤ A1 ≤ 3 mm; and / or, the length of the first air inlet 1021 is A2, 5 mm ≤ A2 ≤ 50 mm.

[0054] In this embodiment, the height of the first air inlet 1021 is between 0.5 mm and 3 mm, which can intercept most of the food ingredients, preventing them from entering and clogging the first air inlet 1021. If the height of the first air inlet 1021 is less than 0.5 mm, processing becomes difficult and exhaust efficiency is low; if the height of the first air inlet 1021 is greater than 3 mm, it loses its function of intercepting food ingredients. The length of the first air inlet 1021 is between 5 mm and 50 mm. The first air inlet 1021 has a relatively large length, thereby reducing the risk of food ingredients such as rice paste, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet 1021. If the length of the first air inlet 1021 is less than 5 mm, food ingredients can easily clog it completely; if the length of the first air inlet 1021 is greater than 50 mm, the anti-clogging insert 102 will be too large, resulting in a disproportionate size with other parts of the cover assembly.

[0055] In one specific embodiment, the height of the first air inlet 1021 is A1, 0.5 mm ≤ A1 ≤ 3 mm, and the length of the first air inlet 1021 is A2, 5 mm ≤ A2 ≤ 50 mm.

[0056] In a preferred embodiment, the height of the first air inlet 1021 is 1 mm, which can intercept most of the food.

[0057] In a preferred embodiment, the length of the first air inlet 1021 is 15 mm.

[0058] In one embodiment, the ball seat 1 includes a ball seat body 101 and an anti-blocking insert 102 connected as one piece. The ball seat body 101 is made of plastic, the anti-blocking insert 102 is made of metal, the anti-blocking cover 2 is made of metal, and the anti-blocking cover 2 is detachably connected to the anti-blocking insert 102.

[0059] In this embodiment, since the anti-blocking insert 102 is a metal part and the anti-blocking cover 2 is a metal part, and the anti-blocking cover 2 and the anti-blocking insert 102 are detachably connected, no powder will fall off during the assembly and disassembly of the anti-blocking insert 102 and the anti-blocking cover 2.

[0060] In one specific embodiment, the connecting portion 202 of the anti-blocking cover 2 is machined with internal threads, and the outer wall of the anti-blocking insert 102 is machined with internal threads. The anti-blocking insert 102 and the anti-blocking cover 2 are connected by threads, which makes it easy to disassemble the anti-blocking cover 2 for cleaning.

[0061] In other alternative embodiments, the anti-clogging insert 102 and the anti-clogging cover 2 may be connected by snap-fit.

[0062] In one embodiment, the anti-blocking insert 102 is injection molded integrally with the ball seat body 101.

[0063] In this embodiment, the anti-blocking insert 102 and the ball seat body 101 are injection molded together. Under the premise that the anti-blocking insert 102 is a metal part, the anti-blocking insert 102 and the ball seat body 101 are connected as one piece, reducing the number of parts and assembly steps, and there is no gap between the anti-blocking insert 102 and the ball seat body 101.

[0064] In one specific embodiment, during processing, the anti-blocking insert 102 is first processed, and then the anti-blocking insert 102 is placed into the injection mold used to make the ball seat body 101, and then injection molding is performed. After injection molding, the anti-blocking insert 102 and the ball seat body 101 become an inseparable whole.

[0065] In one embodiment, the ball seat body 101 is provided with a first buckle 1011, and the anti-blocking insert 102 is provided with a second buckle 1022, the second buckle 1022 cooperating with the first buckle 1011.

[0066] In this embodiment, the ball seat body 101 is provided with a first buckle 1011, and the anti-blocking insert 102 is provided with a second buckle 1022. The second buckle 1022 cooperates with the first buckle 1011. After injection molding, the ball seat body 101 and the anti-blocking insert 102 are not detachable, which can ensure the stability of the ball seat body 101 and the anti-blocking insert 102 being connected as one.

[0067] As shown in the figure, the first buckle 1011 and the second buckle 1022 have a concave-convex structure. The first buckle 1011 includes a first protrusion and a first groove, and the second buckle 1022 includes a second protrusion and a second groove. The first protrusion, the first groove, the second protrusion and the second groove are all arranged in the horizontal direction. The first protrusion is embedded in the second groove, and the second protrusion is embedded in the first groove.

[0068] In one embodiment, the second air inlet 2011 includes a plurality of radially arranged through holes; the diameter of the through holes is D, 0.5 mm ≤ D ≤ 3 mm; and / or, the total area of ​​the plurality of through holes is > 30 mm. 2 .

[0069] In this embodiment, the second air inlet 2011 includes a plurality of radially arranged through holes, the number of which is sufficient, and the total area of ​​the plurality of through holes is greater than 30 mm. 2 This effectively reduces the chance of rice paste, rice grains, mung beans, mixed grains, seaweed, and other ingredients completely clogging the air vents during cooking. The vent diameter is D, 0.5mm ≤ D ≤ 3mm. The vents can intercept most of the mixed grains, preventing them from entering the airflow channel.

[0070] In this embodiment, the second air inlet 2011 includes multiple radially arranged through holes, the total area of ​​which is greater than 30 mm. 2 The side wall of the ball seat 1 is provided with a first air inlet 1021 that communicates with the airflow channel. The length of the first air inlet 1021 is A2, 5 mm ≤ A2 ≤ 50 mm. In a low probability case, when all the through holes are blocked by food, the first air inlet 1021 will not be blocked.

[0071] Specifically, such as Figure 3 As shown, the through hole is a round hole.

[0072] In a preferred embodiment, the diameter of the through hole is 1 mm, which can intercept most of the grains and prevent them from entering the airflow channel.

[0073] According to an embodiment of the present invention, in a second aspect, a cover assembly is also provided, including an insulating cover plate 3 and an exhaust assembly provided in the above embodiments, wherein a ball seat 1 is sealed to the insulating cover plate 3.

[0074] The lid assembly features a first air inlet 1021 on the side wall of the ball seat 1 and a second air inlet 2011 on the main body 201 of the anti-clogging cover 2. During cooking, the generated steam can enter the airflow channel of the ball seat 1 through both the first and second air inlets 1021 and 2011, increasing the exhaust area and improving exhaust capacity. Even if the second air inlet 2011 is blocked, exhaust can still be achieved through it, preventing the serious safety hazard caused by a continuous increase in pressure inside the pot when blocked. Furthermore, because the first air inlet 1021 is higher than the connecting part 202, the airflow path inside the pot is initially upward, then turns, entering the airflow channel inside the ball seat 1 through the first air inlet 1021. This complex airflow path reduces the risk of food items such as rice paste, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet 1021. The ball seat 1 is sealed to the heat-insulating cover plate 3, which can prevent steam generated during cooking from entering the interior of the cover assembly through the gap between the ball seat 1 and the heat-insulating cover plate 3.

[0075] In one embodiment, the heat-insulating cover plate 3 includes a main body 301 and a protrusion 302. The protrusion 302 protrudes in a direction away from the inner cavity of the pot. The protrusion 302 is annular, and the inner side of the protrusion 302 is sealed to the ball seat 1 by a sealing ring 4.

[0076] In this embodiment, the heat-insulating cover 3 includes a main body 301 and a protrusion 302. The protrusion 302 protrudes in a direction away from the inner cavity of the pot. The protrusion 302 is annular. The inner side of the protrusion 302 is sealed to the ball seat 1 by a sealing ring 4. Therefore, the space occupied by the anti-blocking cover 2 and the ball seat 1 in the inner cavity of the pot can be saved. The height of the anti-blocking cover 2 is increased, and the difficulty of food overflowing into the second air inlet 2011 of the anti-blocking cover 2 and the first air inlet 1021 of the ball seat 1 is increased. This can reduce the risk of the second air inlet 2011 and the first air inlet 1021 being blocked by food.

[0077] In one embodiment, the height of the protrusion 302 protruding from the main body 301 is A3, where 2 mm ≤ A3 ≤ 15 mm.

[0078] In this embodiment, the height of the protrusion 302 protruding from the main body 301 is A3, where 2 mm ≤ A3 ≤ 15 mm. This can save space occupied by the anti-blocking cover 2 and the ball seat 1 in the inner cavity of the pot, increase the height of the anti-blocking cover 2, and increase the difficulty of food overflowing into the second air inlet 2011 of the anti-blocking cover 2 and the first air inlet 1021 of the ball seat 1. This can reduce the risk of the second air inlet 2011 and the first air inlet 1021 being blocked by food.

[0079] In a preferred embodiment, the protrusion 302 protrudes from the main body 301 by a height of 5 mm.

[0080] In one embodiment, the top of the connecting portion 202 is higher than the main body portion 301.

[0081] In this embodiment, since the top of the connecting part 202 is higher than the main body 301, the airflow path inside the pot is first upward, enters the space inside the protrusion 302, then turns, and enters the airflow channel inside the ball seat 1 through the first air inlet 1021. The complex airflow path inside the pot reduces the risk of food such as rice milk, rice grains, mung beans, mixed grains, seaweed, etc. clogging the first air inlet 1021.

[0082] In one embodiment, the top of the connecting portion 202 includes an annular first plane 2021 and a second plane 2022, the second plane 2022 being located inside the first plane 2021 and lower than the first plane 2021.

[0083] In this embodiment, the top of the connecting portion 202 includes an annular first plane 2021 and a second plane 2022. The second plane 2022 is located inside the first plane 2021 and is lower than the first plane 2021. The first plane 2021 is equivalent to adding baffles around the anti-blocking cover 2. The airflow enters the first air inlet 1021 by rising to a certain height and then turning, which is a complex path and further improves the anti-blocking effect.

[0084] In one embodiment, such as Figure 7 As shown, the height of the first plane 2021 above the second plane 2022 is A4, where 0.5 mm ≤ A4 ≤ 3 mm.

[0085] In one embodiment, the top of the first air inlet 1021 is below the sealing ring 4.

[0086] In this embodiment, the top of the first air inlet 1021 is lower than the sealing ring 4, which can ensure that the airflow can smoothly enter the first air inlet 1021.

[0087] According to an embodiment of the present invention, a third aspect also provides a cooking apparatus, including the lid assembly provided in the above embodiments.

[0088] This cooking device features a first air inlet 1021 on the side wall of the ball base 1 and a second air inlet 2011 on the main body 201 of the anti-clogging cover 2. During cooking, the generated steam can enter the airflow channel of the ball base 1 through both the first and second air inlets 1021 and 2011, increasing the exhaust area and improving exhaust capacity. Even if the second air inlet 2011 is blocked, exhaust can still be achieved through it, preventing the serious safety hazard caused by a continuous increase in pressure inside the pot when blocked. Furthermore, because the first air inlet 1021 is higher than the connecting part 202, the airflow path inside the pot is initially upward, then turns, entering the airflow channel inside the ball base 1 through the first air inlet 1021. This complex airflow path reduces the risk of food items such as rice paste, rice grains, mung beans, mixed grains, and seaweed clogging the first air inlet 1021.

[0089] The cooking equipment can specifically be a micro-pressure rice cooker, an electric pressure cooker, etc.

[0090] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
