Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a pressure cooking appliance. Background Art

[0002] Due to the unique characteristics of pressure cooking appliances (such as pressure cookers), when working, the inner pot needs to be in contact with and bear pressure on the pressure-bearing member (usually a heat preservation cover or an outer pot outside the inner pot). In the prior art, there are generally two types of mating positions between the pressure-bearing member and the inner pot, that is, the pressure-bearing positions.

[0003] One is rim pressure-bearing, that is, the rim of the inner pot is provided with a flanging, and the flanging is leaned against the rim of the pressure-bearing member, so that the rim of the pressure-bearing member bears the pressure of the inner pot. In this way, since the rim of the inner pot is in contact with the pressure-bearing member and there is no gap between the two, when the user takes out the inner pot after cooking, the user needs to use fingers to pick the rim of the inner pot, which is very inconvenient to operate and easy to get scalded. In addition, since the outward flanging of the rim of the inner pot has relatively low strength, it is easy to deform when abutting against the pressure-bearing member under pressure. Once deformed, risks such as air leakage and pressure relief will occur, making the pressure cooking unable to proceed normally.

[0004] In addition, if the pressure cooking appliance is also equipped with components such as a steamer, the steamer needs to lean against the rim of the inner pot. In this way, not only the distance between the steamer and the pot lid is small, and the food in the steamer will interfere with components such as the exhaust valve and the float valve on the pot lid, affecting normal exhaust and pressure relief, but also the setting of the steamer will affect the abutment of the sealing ring on the pot lid and the flanging of the inner pot, resulting in a decrease in sealing performance.

[0005] Another way is waist pressure-bearing, that is, the contact position between the inner pot and the pressure-bearing member is the lower section of the inner pot (below the midline of the inner pot), so that the flanging at the rim of the inner pot can be higher than the pressure-bearing member, and thus a gap is formed between the flanging and the pressure-bearing member, which is convenient for the user to grab the inner pot.

[0006] The specific solution for waist pressure-bearing is that a pressure-bearing step is provided at the bottom of the heat preservation cover, and a pressure-bearing concave platform that is recessed inward is provided at the lower section of the inner pot. The heat preservation cover bears the downward pressure of the inner pot through the cooperation of the pressure-bearing concave platform and the pressure-bearing step of the heat preservation cover. However, since the waist of the inner pot is recessed inward to form the pressure-bearing concave platform, the side part of the inner pot is formed into two parts, an upper arc section and a lower arc section, so that the overall shape of the inner pot changes greatly compared with the traditional inner pot, and the acceptance degree of users is different. In addition, the pressure-bearing concave platform divides the upper and lower arc sections, making the side wall of the inner pot discontinuous. Furthermore, the water level line on the side wall of the inner pot is divided into two discontinuous sections by the pressure-bearing concave platform, which is not conducive to guiding the user to use the product and affects the use experience. Summary of the Utility Model

[0007] The present utility model provides a pressure cooking appliance to solve the problems that the existing pressure-bearing method between the inner pot and the pressure-bearing member makes it inconvenient to take out the inner pot, and due to the setting of the inner pot pressure-bearing structure, the shape of the inner pot changes greatly and the water level line is divided, affecting the user experience.

[0008] The technical solution adopted by the present utility model is as follows:

[0009] A pressure cooking appliance includes a pot body, a pot lid, and an inner pot placed in the pot body. The pot body has a pressure-bearing ring for locking with the pot lid. The pressure-bearing ring includes a rim provided with pot teeth, a first vertical section, and a horizontal pressure-bearing section located below the first vertical section; the inner pot has a mouth area above the highest water level line. The mouth area is provided with a flanging, a vertical pot wall section, a mating section abutting against the horizontal pressure-bearing section, and a neck closing section located below the mating section. The height of the vertical pot wall section is greater than that of the first vertical section, so that there is a gap between the flanging and the rim.

[0010] The pressure cooking appliance of the present utility model further has the following additional technical features:

[0011] The pressure-bearing ring further includes a second vertical section located below the horizontal pressure-bearing section. The horizontal pressure-bearing section extends in an arc to form a pressure-bearing arc surface on the side facing the inner pot.

[0012] The side wall of the inner pot is provided with an arc section, and the arc section extends from the neck closing section to the bottom of the inner pot.

[0013] The maximum outer diameter of the arc section is smaller than the outer diameter of the vertical pot wall section.

[0014] The mating section is recessed towards the inside of the inner pot to form at least part of the area of the neck closing section, and the outer surface of the mating section forms a mating step for mating with the horizontal pressure-bearing section.

[0015] The inner pot has a height median line and a high line located above the height median line and parallel to the height median line. The distance between the high line and the flanging is 10 mm, and the mating section is arranged between the high line and the height median line.

[0016] The pressure cooking appliance further includes an electromagnetic coil disk fixed below the pressure-bearing ring. The electromagnetic coil disk has a bottom coil and a side coil, and the projection of the side coil towards the inner pot covers the height median line.

[0017] The pot lid is provided with a sealing ring. The sealing ring has a sealing lip extending downwards. The sealing lip is located inside the inner pot and abuts and seals against the vertical pot wall section, so that the pot lid and the inner pot cooperate to form a cooking cavity.

[0018] The pressure cooking appliance further includes a partition member located inside the inner pot. The partition member abuts against the mating section to divide the inner pot internal space into a first cooking space located below the partition member and a second cooking space located above the partition member.

[0019] The pressure cooking appliance further includes an electromagnetic wire coil fixed below the pressure-bearing ring. The bottom of the pressure-bearing ring is provided with a fixed flange, and the electromagnetic wire coil is fixed to the fixed flange.

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by the present utility model are as follows:

[0021] 1. In the present utility model, the pressure-bearing ring is provided with a first vertical section and a horizontal pressure-bearing section below the mouth edge. The horizontal pressure-bearing section extends inward horizontally relative to the first vertical section to form a pressure-bearing step for supporting the inner pot. The inner pot has a mouth area, and the mouth area has a flange and a mating section located below the flange. The mating section abuts and cooperates with the horizontal pressure-bearing section to achieve pressure-bearing. In this way, the pressure-bearing position of the inner pot is transferred to the neck of the inner pot. Moreover, the height of the vertical wall section of the inner pot is greater than that of the first vertical section, so that on the one hand, the flange is higher than the mouth edge, and there is a gap between the two, which is convenient for the user to grasp the flange of the inner pot to take and place the inner pot. On the other hand, the pressure-bearing structure of the inner pot is located at the neck of the inner pot, at a relatively high position. Furthermore, the middle and lower parts of the inner pot can be designed as a complete and continuous arc surface or straight surface. On the one hand, this improves the integrity and continuity of the middle and lower parts of the inner pot, improves the aesthetics while ensuring the heat transfer efficiency, enabling the heat to be quickly transferred between the bottom and the middle of the inner pot, thereby improving the even heating of the upper and lower layers of food and ensuring the cooking taste. On the other hand, the pressure-bearing position is above the highest water level line of the inner pot, and the middle and lower parts of the inner pot are complete, so that the pressure-bearing structure avoids the water level line, and a complete and continuous water level line can be provided on the side wall of the inner pot, thereby being able to give the user a clear indication of the food quantity and water quantity, improving the use experience.

[0022] In addition, the vertical wall section of the inner pot is used to cooperate with the sealing ring on the pot lid. The vertical surface makes its contact with the sealing ring closer and more stable, thereby improving the sealing effect of the pot mouth, ensuring normal pressure build-up in the pot, and avoiding air leakage.

[0023] 2. As a preferred embodiment of the present utility model, the pressure-bearing ring further includes a second vertical section located below the horizontal pressure-bearing section. The horizontal pressure-bearing section extends in an arc shape to form a pressure-bearing arc surface on the side facing the inner pot. The pressure-bearing arc surface contacts the mating section of the inner pot, making the contact between the two softer, reducing the wear between the two while also improving the support stability. In addition, when the inner pot is placed on the pressure-bearing arc surface, due to the inclination of the pressure-bearing arc surface, the inner pot will have a tendency to slide downward along the pressure-bearing arc surface under its own gravity, and then the inner pot will slide under the action of gravity to a position centered with the pressure-bearing ring, keeping the axes of the inner pot and the pressure-bearing ring coincident. Furthermore, the pot lid sealing ring is in good contact with the mouth edge of the inner pot, forming a complete seal to prevent air leakage caused by poor contact in some areas between the sealing ring and the mouth edge of the inner pot.

[0024] 3. As a preferred embodiment of the present utility model, the fitting section is recessed towards the interior of the inner container to form at least a partial area of the neck closing section, and a fitting step for cooperating with the lateral pressure-bearing section is formed on the outer surface of the fitting section. The side wall of the inner container is recessed inward to form the fitting section, and at the same time, at least a partial area of the neck closing section is formed. Compared with the way that the fitting section protrudes outward, it can reduce the abruptness of the shape of the inner container and make the shape of the inner container more beautiful. In addition, by forming the neck closing section and the fitting section synchronously in an inwardly concave manner, the structure of the inner container is simplified, the processing difficulty of the inner container is reduced, and the production efficiency and the yield rate are improved.

[0025] 4. As a preferred embodiment of the present utility model, the pressure cooking appliance further includes an electromagnetic wire coil fixed below the pressure-bearing ring. The electromagnetic wire coil has a bottom coil and a side coil, and the projection of the side coil towards the inner container covers the height midline. Since there is no pressure-bearing structure in the middle and waist of the inner container and it is a continuous arc-shaped wall, the side space of the inner container is liberated. Therefore, the upper edge of the electromagnetic wire coil can be raised to the position corresponding to the middle of the inner container, and then the side coil can be correspondingly arranged at the middle position of the inner container. In this way, the bottom coil radiates at least the bottom wall of the inner container, and the side coil radiates the middle of the inner container. During the cooking process, the bottom coil and the side coil heat the inner container simultaneously, so as to heat the bottom and the middle of the inner container at the same time, enabling the upper and lower layers of food to be heated by the coil, thereby further improving the uniformity of food heating and the cooking effect.

[0026] 5. As a preferred embodiment of the present utility model, the pressure cooking appliance further includes a partition member located inside the inner container. The partition member leans on the fitting section to divide the inner space of the inner container into a first cooking space below the partition member and a second cooking space above the partition member. Compared with the way of pressure-bearing at the mouth edge of the inner container, in the present utility model, the pressure-bearing structure at the neck makes the position of the pressure-bearing structure move downward relatively. Therefore, the partition member can lean on the fitting section instead of the flanging of the inner container. In this way, the distance between the partition member and the pot lid is increased, and the risk of interference between the food in the second cooking space and the exhaust component on the pot lid is reduced, ensuring the reliable progress of processes such as exhaust and pressure relief. For the way of pressure-bearing at the waist, if the partition member leans on the pressure-bearing structure at the waist, the lower cooking space will be greatly reduced. During the cooking process, there is a problem that the soup of the lower-layer food pours into the upper cooking space, soaking the upper-layer food and affecting the taste of the upper-layer food. In this embodiment, the partition member leans on the fitting section at the neck of the inner container, so that the setting position of the partition member moves upward relatively, increasing the first cooking space and greatly reducing the risk of the soup in the first cooking space pouring into the second cooking space, ensuring relatively independent cooking in the upper and lower spaces, avoiding phenomena such as flavor mixing, and ensuring the cooking effect of the food in the upper and lower cooking spaces.

[0049] Such as Figure 1 、 Figure 2As shown in the figure, a pressure cooking appliance includes a pot body 1, a pot lid 2, and an inner pot 3 placed inside the pot body 1. The pot body 1 has a pressure-bearing ring 4 for locking with the pot lid 2. The pressure-bearing ring 4 includes a rim 41 provided with pot teeth, a first vertical section 42, and a horizontal pressure-bearing section 43 located below the first vertical section 42. The inner pot 3 has a mouth area above the highest water level line. The mouth area is provided with a flanging 31, a vertical wall section 32 of the inner pot, a mating section 33 in contact with the horizontal pressure-bearing section 43, and a neck closing section 34 located below the mating section 33. The height of the vertical wall section 32 of the inner pot is greater than that of the first vertical section 42, so that there is a gap between the flanging 31 and the rim 41.

[0050] In the present utility model, the pressure-bearing ring 4 is provided with a first vertical section 42 and a horizontal pressure-bearing section 43 below the rim 41. The horizontal pressure-bearing section 43 extends horizontally inward relative to the first vertical section 42 to form a pressure-bearing step for supporting the inner pot 3. The inner pot 3 has a mouth area, and the mouth area has a flanging 31 and a mating section 33 located below the flanging 31. The mating section 33 is in contact and cooperation with the horizontal pressure-bearing section 43 to achieve pressure bearing, so that the pressure-bearing position of the inner pot 3 is transferred to the neck of the inner pot 3. And the height of the vertical wall section 32 of the inner pot 3 is greater than that of the first vertical section 42, so that on one hand, the flanging 31 is higher than the rim 41, and there is a gap between the two, which is convenient for the user to grasp the flanging 31 of the inner pot 3 to take and place the inner pot 3. On the other hand, the pressure-bearing structure of the inner pot 3 is located at the neck of the inner pot 3, at a relatively high position. Furthermore, the middle and lower parts of the inner pot 3 can be designed as a complete and continuous arc surface or straight surface. In this way, on the one hand, the integrity and continuity of the middle and lower parts of the inner pot 3 are improved, the aesthetics is improved, and at the same time, the heat transfer efficiency is ensured, so that the heat can be quickly transferred between the bottom and the middle of the inner pot 3, thereby improving the even heating of the upper and lower layer of food and ensuring the cooking taste. On the other hand, the pressure-bearing position is above the highest water level line of the inner pot 3, and the middle and lower parts of the inner pot 3 are complete, so that the pressure-bearing structure avoids the water level line, and a complete and continuous water level line can be provided on the side wall of the inner pot 3, so that the user can be given a clear indication of the amount of food and water, improving the use experience.

[0051] In addition, the vertical wall section 32 of the inner pot 3 is used to cooperate with the sealing ring on the pot lid 2. The vertical surface makes its contact with the sealing ring closer and more stable. And compared with the pressure-bearing method of the rim of the inner pot 3, the strength of the mating section 33 is higher than that of the flanging 31 of the inner pot, so it is not easy to deform when being pressed, and thus the uniform sealing performance at all parts of the periphery of the sealing ring can be ensured, ensuring normal pressure build-up in the pot and avoiding air leakage.

[0052] It should be noted that in the present utility model, the vertical wall section 32, the first vertical section 42, and the second vertical section 44 can be walls extending in the vertical direction, or can extend up and down at a certain inclination angle according to the needs of the manufacturing process, which is not limited herein.

[0053] It should be noted that for most of the circular inner liners 3, due to the processing technology of arc bulging, a neck closing section 34 will be formed at the neck of the inner liner 3. Therefore, the neck closing section 34 can be used as a reference. The mating section 33 is located above the neck closing section 34, so that the pressure-bearing position of the inner liner 3 is above the neck closing section 34.

[0054] Moreover, in the present utility model, it is not limited that the mating section 33 is located at the neck of the inner liner 3, and its position can also be moved downwards. For example, it can be located at a position slightly above the middle of the inner liner 3, as long as it is above the highest water level line of the inner liner 3, and no limitation is made thereto.

[0055] Preferably, as Figure 2 、 Figure 5 shown, the side wall of the inner liner 3 is provided with an arc section 35, and the arc section 35 extends from the neck closing section 34 to the bottom of the inner liner 3.

[0056] The arc section 35 on the side wall of the inner liner 3 is continuous between the middle and the bottom of the inner liner 3, and the arc surface is complete, with a neat appearance. The polishing process is simpler and more convenient, and the printing of the water level line is also more convenient. At the same time, it is convenient for users to clean the inner liner 3. In addition, the complete and continuous arc surface also releases the space on the side of the inner liner 3. The electromagnetic wire coil 5 can be arranged on the outer side of the inner liner 3 below the neck closing section 34, so that the coil covers both the bottom and the middle of the inner liner 3 at the same time, and the heating coverage area is greatly released.

[0057] Furthermore, as Figure 5 shown, the maximum outer diameter D1 of the arc section 35 is smaller than the outer diameter D2 of the vertical wall section 32.

[0058] The outer diameter of the arc section 35 is smaller and the outer diameter of the vertical wall section 32 is larger. On the one hand, it enables the mating section 33 to be reliably placed on the horizontal pressure-bearing section 43 and provides a stable supporting force for the inner liner 3, and ensures that the arc section 35 can smoothly extend into the pressure-bearing ring 4 to avoid interference with the pressure-bearing ring 4. On the other hand, it can further release the space on the outer peripheral side of the arc section 35, so that the coil of the electromagnetic wire coil 5 can cover more areas of the inner liner 3 in the height direction of the inner liner 3, improving the heating effect on the inner liner 3.

[0059] As a preferred embodiment of the present utility model, as Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 shown, the pressure-bearing ring 4 further includes a second vertical section 44 located below the horizontal pressure-bearing section 43, and the horizontal pressure-bearing section 43 extends in an arc shape to form a pressure-bearing arc surface 431 on the side facing the inner liner 3.

[0060] The cooperating section 33 of the pressure-bearing arc surface 431 contacts the inner container 3, making the contact between the two softer. While reducing the wear between the two, it also improves the support stability. In addition, when the inner container 3 is placed on the pressure-bearing arc surface 431, due to the inclination of the pressure-bearing arc surface 431, the inner container 3 will tend to slide downward along the pressure-bearing arc surface 431 under its own gravity, and then the inner container 3 will slide under the action of gravity to a position centered with the pressure-bearing ring 4, keeping the axes of the inner container 3 and the pressure-bearing ring 4 coincident. Furthermore, the sealing ring of the pot lid 2 is in good contact with the rim of the inner container 3, forming a seal around, preventing air leakage caused by poor contact in some areas between the sealing ring and the rim of the inner container 3.

[0061] The setting of the second vertical section 44 facilitates the fixation of the pressure-bearing ring 4 and the electromagnetic wire coil 5. While reducing the assembly difficulty, it also makes the overall consistency better after the electromagnetic wire coil 5 is installed on the pressure-bearing ring 4, improving the aesthetics and stability.

[0062] Preferably, the outer side wall of the cooperating section 33 is also an arc surface structure to contact the pressure-bearing arc surface 431, improving the stability of the contact between the two.

[0063] It should be noted that the structure of the cooperating section 33 of the present utility model is not limited. In a preferred embodiment, as Figure 2 、 Figure 3 、 Figure 5 shown, the cooperating section 33 is recessed towards the inside of the inner container 3 to form at least part of the neck closing section 34, and the outer surface of the cooperating section 33 forms a cooperating step for cooperating with the horizontal pressure-bearing section 43.

[0064] The side wall of the inner container 3 is recessed inward to form the cooperating section 33 and at the same time constitutes at least part of the neck closing section 34. Compared with the way that the cooperating section 33 protrudes outward, it can reduce the abruptness of the shape of the inner container 3 and make the shape of the inner container 3 more beautiful. In addition, by forming the neck closing section 34 and the cooperating section 33 synchronously in an inward concave manner, the structure of the inner container 3 is also simplified, the processing difficulty of the inner container 3 is reduced, and the production efficiency and the qualified product rate are improved. In addition, by forming the cooperating section 33 in an inward concave manner, the size design of the inner container 3 is simpler, the processing is more convenient, and the accuracy is easier to guarantee, thereby reducing the processing and assembly errors and ensuring reliable abutment between the inner container 3 and the pressure-bearing ring 4. And it can improve the strength of the inner container 3 at the cooperating section 33 and reduce the possibility of deformation of the inner container 3.

[0065] In other embodiments, a convex structure can also be provided on the outer wall of the inner container 3, or the cooperating section 33 can protrude outward to form a step for cooperating with the horizontal pressure-bearing section 43, which is not limited herein.

[0066] Preferably, as Figure 5As shown, the inner pot 3 has a height median line 36 and a high line 37 located above the height median line 36 and parallel to it. The distance between the high line 37 and the flanging 31 is 10 mm, and the mating section 33 is arranged between the high line 37 and the height median line 36.

[0067] The distance between the mating section 33 and the top end of the inner pot 3 is not less than 10 mm, so as to leave enough sealing area for the sealing ring on the pot lid 2. The sealing ring on the pot lid 2 abuts and seals against the area above the mating section 33 of the inner pot 3. The surface of the mating section 33 is relatively tortuous, and the surface of the vertical wall section 32 above is relatively flat. Therefore, it is easier to form a good seal with the sealing ring, avoiding interference between the sealing ring and the mating section 33 and ensuring the sealing effect.

[0068] As a preferred embodiment of the present invention, as Figure 2 、 Figure 5 shown, the pressure cooking appliance further includes an electromagnetic wire. The electromagnetic wire coil 5 is fixed below the pressure-bearing ring 4. The electromagnetic wire coil 5 has a bottom coil and a side coil, and the projection of the side coil towards the inner pot 3 covers the height median line 36.

[0069] Since there is no pressure-bearing structure in the middle and waist of the inner pot 3, which is a continuous arc-shaped wall, the side space of the inner pot 3 is liberated. Therefore, the upper edge of the electromagnetic wire coil 5 can be raised to the position corresponding to the middle of the inner pot 3, and then a side coil can be correspondingly arranged at the middle position of the inner pot 3. In this way, the bottom coil at least radiates the bottom wall of the inner pot 3, and the side coil radiates the middle of the inner pot 3. During the cooking process, the bottom coil and the side coil heat the inner pot 3 simultaneously, so as to be able to heat the bottom and the middle of the inner pot 3 at the same time, enabling the upper and lower layers of food to be heated by the coil, thereby further improving the evenness of food heating and the cooking effect.

[0070] Specifically, as Figure 2 、 Figure 4 shown, the electromagnetic wire coil 5 includes a bottom arc-shaped disk body 53 and a vertical wall 54 extending upward from the upper edge of the arc-shaped disk body 53. The vertical wall 54 is provided with a side winding area 52, and the side coil is wound around the side winding area 52. The arc-shaped disk body 53 is provided with a bottom winding area 51, and the bottom coil is wound around the bottom winding area 51. Among them, the vertical wall 54 and the arc-shaped disk body 53 can be of a split structure, and the two are fixedly connected by subsequent screws, snap connections, etc., or the two can be integrally formed, so that the bottom coil and the side coil can be wound with a continuous and uninterrupted coil, reducing the winding difficulty.

[0071] Preferably, as Figure 6 、 Figure 7 shown, the bottom of the pressure-bearing ring 4 is provided with a fixed flanging 45, and the electromagnetic wire coil 5 is fixed to the fixed flanging 45.

[0072] The setting of the fixed flanging 45 forms an installation plane on the pressure-bearing ring 4, and is fixed to the electromagnetic wire coil 5 through the installation plane, making the connection between the two simpler and more stable. Specifically, in one embodiment, the fixed flanging 45 and the electromagnetic wire coil 5 are provided with fixing holes, and the two are fastened and connected by a fastener (such as a screw) passing through the fixing holes. The fixing of the pressure-bearing ring 4 and the electromagnetic wire coil 5 can also be achieved by means of snap connection, screwing, threaded connection, etc., which is not limited here.

[0073] As a preferred embodiment of the present utility model, as Figure 1 shown, the pot lid 2 is provided with a sealing ring, and the sealing ring has a downwardly extending sealing lip 21. The sealing lip 21 is located inside the inner pot 3 and abuts and seals against the vertical wall section 32 of the inner pot, so that the pot lid 2 and the inner pot 3 cooperate to form a cooking cavity.

[0074] The vertical surface makes its abutment with the sealing ring closer and more stable, thereby improving the sealing effect of the pot mouth, ensuring normal pressure build-up inside the pot, and avoiding air leakage. At the same time, after the pressure builds up inside the pot, under the action of the air pressure, the sealing lip 21 will expand and deform outward. Since the sealing lip 21 is located inside the vertical wall section 32 of the inner pot, its deformation will be blocked by the vertical wall section 32 of the inner pot when it deforms, thereby making the abutment between the sealing lip 21 and the vertical wall section 32 of the inner pot closer, and further improving the sealing effect.

[0075] Preferably, as Figure 8 、 Figure 9 shown, the pressure cooking appliance further includes a partition member 6 located inside the inner pot 3. The partition member 6 abuts against the mating section 33 to divide the inner space of the inner pot 3 into a first cooking space 61 below the partition member 6 and a second cooking space 62 above the partition member 6.

[0076] Compared with the way of bearing pressure at the rim of the inner pot 3, in the present utility model, the way of bearing pressure at the neck makes the position of the pressure-bearing structure move downward relatively. Thus, the partition member 6 can abut against the mating section 33 instead of the flanging 31 of the inner pot 3, which increases the distance between the partition member 6 and the pot lid 2, reduces the risk of interference between the food in the second cooking space 62 and the exhaust assembly on the pot lid 2, and ensures the reliable progress of processes such as exhaust and pressure relief.

[0077] In the prior art, in the way of bearing pressure at the waist, if the partition member 6 abuts against the pressure-bearing structure at the waist, the lower cooking space will be greatly reduced. During the cooking process, there is a problem that the food soup in the lower layer surges into the upper cooking space, soaking the upper food and affecting the taste of the upper food.

[0078] In this embodiment, the partition 6 abuts against the mating section 33 at the neck of the inner container 3, so that the installation position of the partition 6 is relatively shifted upward, increasing the first cooking space 61 and greatly reducing the risk of the soup in the first cooking space 61 flowing into the second cooking space 62, ensuring relatively independent cooking in the upper and lower spaces, avoiding phenomena such as flavor mixing, and ensuring the cooking effect of the food in the upper and lower cooking spaces.

[0079] It should be noted that the structure of the partition 6 in the present utility model is not limited. It can be a steamer structure with holes provided in the bottom wall to be able to steam food using the steamer or sterilize tableware using high-temperature and high-pressure steam. Of course, the partition 6 can also be a structure with a closed bottom wall to be able to cook soup-like foods or cook rice, etc. using the partition 6.

[0080] What is not described in the present utility model can be achieved by adopting or referring to the existing technology.

[0081] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0082] The above description is only for the embodiments of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and changes can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
