Detailed implementation manners

[0039] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] In the various specific technical features described in the specific embodiments, they can be combined in any suitable manner without conflict. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination manners of the various specific technical features in the present application will not be described separately.

[0041] In the following description, the terms "first", "second", etc. are only used to distinguish different objects, and do not indicate any identity or relationship between the objects. It should be understood that the orientation descriptions such as "above", "below", "outside", and "inside" are all in the normal orientation of use, which can be the left-right direction in the normal use state or not.

[0042] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or apparatus comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent in such process, method, article or apparatus. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising the element. "Plurality" means greater than or equal to two.

[0043] In the related art, cooking utensils are mainly of two types: round and square. Among them, the cooking utensils with pressure cooking function are generally round at present. The inner pot of the round cooking utensil is limited by its shape and is mainly suitable for small-volume or regular-shaped ingredients, such as cut vegetables, meat pieces, etc. For large-volume, long-shaped ingredients, such as whole chickens, ducks, fish, large steaks, etc., they are not suitable. Since the square cooking utensil has a border with corners, especially if the sealing ring cannot fit effectively at the joint of two sides, there will be a problem that it cannot be completely sealed. The sealing ring is lifted along with the container lid under the pressure in the cooking cavity, reducing the sealing performance between the sealing ring and the cooking main body. Therefore, square cooking utensils are basically non-pressure, such as slow cookers and electric hot pots, with a long cooking time. Square cooking utensils can meet more cooking scenarios and are suitable for different types of ingredients. Non-sealed cooking is difficult to fully extract the nutrients in food and may cause nutrient loss.

[0044] In view of this, please refer to Figure 1 - Figure 2 , an embodiment of the present application provides a cooking utensil 1000 that can be used for high-pressure cooking. An embodiment of the present application also provides a cooking main body 300, please refer to Figure 3 - Figure 5, the cooking main body 300 has a cooking cavity 300a, a bearing surface 310 located above the cooking cavity 300a, and a limiting surface 320 located above the bearing surface 310. The side wall surface 301 of the cooking cavity 300a includes a first wall surface 3011 arranged oppositely along a first direction, a second wall surface 3012 arranged oppositely along a second direction, and a first corner surface 3013 connected between the first wall surface 3011 and the second wall surface 3012. The first corner surface 3013 is an arc surface. The limiting surface 320 includes a first sub-surface 321 arranged oppositely along the first direction, a second sub-surface 322 arranged oppositely along the second direction, and a second corner surface 323 connected between the first sub-surface 321 and the second sub-surface 322. The second corner surface 323 is an arc surface. The radius of the first corner surface 3013 is greater than the radius of the second corner surface 323. In the figure, X represents the first direction and Y represents the second direction.

[0045] The cooking appliance 1000 has a square container lid 200 and a cooking main body 300 for accommodating food materials. The container lid 200 is covered on the cooking main body 300 to form a closed cooking cavity 300a. A sealing ring 100 is arranged between the container lid 200 and the cooking main body 300 for sealing, so that when the cooking appliance 1000 is cooking, the temperature and pressure in the cooking main body 300 can rise rapidly, improving the cooking efficiency.

[0046] When the cooking appliance 1000 is cooking, steam will be generated in the cooking cavity 300a of the cooking main body 300. As the steam gradually increases, the pressure in the cooking cavity 300a of the cooking main body 300 will gradually rise and push up the container lid 200, weakening the sealing effect of the sealing ring 100. In order to improve the sealing performance between the sealing ring 100 and the cooking main body 300, in the cooking main body 300 provided by the embodiment of the present application, the radius of the first corner surface 3013 is greater than the radius of the second corner surface 323, which can cooperate with the sealing ring 100 during the cooking process to improve the sealing effect.

[0047] Specifically, before cooking, the sealing ring 100 is pressed on the bearing surface 310. In the initial stage of cooking, when the amount of steam generated after heating and cooking is not enough to push up the container lid 200, the sealing ring 100 is pressed on the bearing surface 310 of the cooking main body 300 by gravity or an external locking mechanism 400 to seal between the cooking main body 300 and the sealing ring 100. At this time, steam cannot flow out between the sealing ring 100 and the cooking main body 300. In this way, as the heating time of the cooking main body 300 increases, the inside of the cooking main body 300 can remain in a sealed state and the pressure increases rapidly.

[0048] As the heating time of the cooking main body 300 further increases, under the action of the pressure accumulated inside, two-stage sealing can be achieved between the bearing surface 310 and the side wall surface 301 and the sealing ring 100, and a two-stage sealing effect can be achieved on the cooking main body 300 during cooking. Moreover, the radius of the first corner surface 3013 is relatively large, so that the contact area between the first corner surface 3013 and the sealing ring 100 is larger, which is conducive to better achieving sealing; the radius of the second corner surface 323 is relatively small, which can extend the flow channel length at the corner, increase the flow resistance, improve the sealing performance, quickly increase the pressure inside the cooking main body 300, speed up the cooking speed, and improve the cooking effect.

[0049] In some embodiments, the radius of the first corner surface is greater than or equal to 40 mm, and the radius of the first corner surface 3013 is less than or equal to 100 mm.

[0050] The radius of the first corner surface 3013 refers to the radius of the circular arc line formed by the intersection of the plane perpendicular to the up and down direction and the first corner surface 3013.

[0051] In some embodiments, the radius of the second corner surface is greater than or equal to 10 mm, and the radius of the second corner surface 323 is less than or equal to 35 mm.

[0052] The radius of the second corner surface 323 refers to the radius of the circular arc line formed by the intersection of the plane perpendicular to the up and down direction and the second corner surface 323.

[0053] In some embodiments, the cooking main body 300 includes a containing device, and the cooking cavity 300a, the bearing surface 310 and the limiting surface 320 are all formed on the containing device.

[0054] Among them, the containing device can be an inner container 340.

[0055] In some other embodiments, the containing device is an inner container 340, and the cooking cavity 300a further includes an outer pot 330, and the inner container 340 is installed inside the outer pot 330. Exemplarily, please refer to Figure 1 , the cooking main body 300 may include an outer pot 330 and an inner container 340. The outer pot 330 is used to install the inner container 340 and the heating device for heating the inner container 340. The outer pot 330 is formed with an installation cavity, the inner container 340 is located in the installation cavity of the outer pot 330, and the inner container 340 is formed with a cooking cavity 300a for containing food materials.

[0056] In some embodiments, the bearing surface 310 is a plane.

[0057] In this way, the fitting effect between the bearing surface 310 and the sealing ring 100 can be improved, the sealing performance can be improved, the pressure in the cooking cavity 300a can be quickly increased, the cooking speed can be accelerated, and the cooking effect can be improved.

[0058] In some embodiments, the cooking main body 300 has a cooking cavity 300a, a bearing surface 310 located above the cooking cavity 300a, and a limiting surface 320 located above the bearing surface 310. The shape of the inner edge line of the bearing surface 310 is arc-shaped, the shape of the outer edge line of the bearing surface 310 is arc-shaped, the radius of the inner edge line is greater than the radius of the outer edge line, and the bearing surface 310 is a flat surface.

[0059] The radius of the inner edge line of the bearing surface 310 being greater than the radius of the outer edge line helps to improve the sealing effect of the sealing ring 100 of the cooking main body 300, can extend the flow path length at the corner, increase the flow resistance, rapidly increase the pressure inside the cooking main body 300, speed up the cooking speed, and improve the cooking effect.

[0060] In some embodiments, referring to Figure 6 - Figure 8 , the cooking appliance 1000 includes a sealing ring 100, a container lid 200, and the cooking main body 300 according to any one of the above; the sealing ring 100 is arranged on the cooking main body 300; the container lid 200 is connected to the sealing ring 100; the locking mechanism 400 is movably installed on the cooking main body 300, and the locking mechanism 400 is used to lock or unlock the cooking main body 300 and the container lid 200. The sealing ring 100 is in sealing contact with the bearing surface 310 and / or the side wall surface 301 of the cooking cavity 300a when the locking mechanism 400 is in the locked state.

[0061] The cooking main body 300 and the container lid 200 can be locked by the locking mechanism 400. In the initial stage of cooking, the locking mechanism 400 can reduce the possibility that the container lid 200 is lifted and affects the internal sealing effect of the cooking cavity 300a.

[0062] Exemplarily, the locking mechanism 400 and the cooking main body 300 clamp the container lid 200 in the up and down direction to lock the cooking main body 300 and the container lid 200.

[0063] The locking mechanism 400 can play a limiting role on the container lid 200. For example, it presses on the upper end of the container lid 200 in the up and down direction, so that the container lid 200 presses the sealing ring 100 on the bearing surface 310.

[0064] In some embodiments, referring to Figure 8, the sealing ring 100 includes a first seal 10 and a second seal 20. The shape of the projection area of the first seal 10 along the axial direction of the first seal 10 is a square ring, and the first seal 10 is used to seal with the bearing surface 310 of the cooking appliance 1000; the second seal 20 is connected to the inner side of the first seal 10, the second seal 20 is arranged around the circumference of the first seal 10, and at least part of the second seal 20 protrudes from one side of the first seal 10 along the axial direction of the first seal 10, and the second seal 20 is used to seal with the side wall surface 301 of the cooking cavity 300a of the cooking appliance 1000.

[0065] Wherein, the axial direction refers to the sectional direction perpendicular to the circumferential direction of the square ring.

[0066] The first seal 10 is sleeved on the circumference of the container cover 200 in the shape of a square ring, and the first seal 10 is adapted to the shape of the square container cover 200 to achieve a sealing effect. The first seal 10 can play a sealing role between the cooking main body 300 and the sealing cover in the up and down direction, and the second seal 20 can seal the cooking main body 300 in the horizontal direction.

[0067] Specifically, please refer to Figure 8 , when not yet cooked, the first seal 10 is pressed on the bearing surface 310, and the second seal 20 fits against the side wall of the cooking main body 300. The side wall of the cooking main body 300 refers to the inner side wall of the cooking cavity 300a. At the initial stage of cooking, when the amount of steam generated after heating is not enough to lift the container cover 200, the first seal 10 is pressed on the bearing surface 310 of the cooking main body 300 by gravity or an external locking mechanism 400 to play a sealing role between the cooking main body 300 and the sealing cover. At this time, even if the steam escapes from between the second seal 20 and the cooking main body 300, it cannot further flow out from between the first seal 10 and the cooking main body 300. Thus, as the heating time of the cooking main body 300 increases, the inside of the cooking main body 300 can remain in a sealed state, and the pressure increases rapidly.

[0068] As the heating time of the cooking main body 300 further increases, at this time, under the action of the pressure accumulated inside, the second seal 20 can abut against the side wall of the cooking main body 300 for sealing. Thus, relying on the first seal 10 and the second seal 20 can achieve a two-stage sealing effect on the cooking main body 300 during cooking, quickly increase the pressure inside the cooking main body 300, speed up the cooking speed, and improve the cooking effect.

[0069] In some embodiments, please refer to Figure 8 , at least two sealing rings 11 are formed at the bottom of the first seal 10, and the at least two sealing rings 11 are arranged at intervals along the inner and outer direction of the first seal 10, and the second seal 20 is located inside the sealing ring 11.

[0070] The inner direction of the first seal 10 refers to the direction towards the cooking cavity 300a inside the cooking main body 300, and the outer direction of the first seal 10 refers to the direction away from the cooking cavity 300a inside the cooking main body 300.

[0071] By providing the sealing ring 11, the contact area between the sealing ring 11 and the bearing surface 310 of the cooking main body 300 can be reduced, improving the sealing effect. And providing multiple sealing rings 11 can play a multiple sealing role, further improving the sealing effect.

[0072] In some embodiments, please refer to Figure 8 , on one side of the first seal 10 facing the second seal 20 along the axial direction of the first seal 10, there is a target surface 12, the sealing ring 11 protrudes from the target surface 12, and along the axial direction of the first seal 10, the maximum distance between the sealing ring 11 and the target surface 12 is less than the maximum distance between the second connecting member and the target surface 12.

[0073] The maximum distance between the second seal 20 and the target surface 12 refers to the distance from the bottom end of the second seal 20 in the up-and-down direction to the target surface 12. The length dimension of the second seal 20 in the up-and-down direction is greater than the thickness of the sealing ring 11 in the up-and-down direction, so that at least a part of the second seal 20 can be attached to the side wall of the cooking main body 300 to achieve a sealing effect.

[0074] In some embodiments, please refer to Figure 8 , the first seal 10 includes a first wall 13 and a second wall 14. The shape of the projection area of the first wall 13 along the axial direction of the first wall 13 is a square ring; the second wall 14 is located inside the first wall 13, and the second wall 14 is connected to both opposite ends of the first wall 13 along the axial direction of the first wall 13. The first wall 13 and the second wall 14 enclose a receiving cavity 10a for receiving the edge of the container lid 200. The shape of the projection area of the receiving cavity 10a along the axial direction of the first wall 13 is a square ring shape, and the second seal 20 is connected to the second wall 14 at one end, and the second seal 20 is located on the side of the corresponding second wall 14 away from the receiving cavity 10a along the axial direction of the first wall 13.

[0075] The first wall 13 and the second wall 14 enclose to form the receiving cavity 10a towards the cooking cavity 300a inside the cooking main body 300, and the outer circumference of the container lid 200 is located in the receiving cavity 10a. In this way, the seal and the container lid 200 can be attached to each other, so that the seal can be closely attached to the surface of the container lid 200 to play a sealing role between the cooking main body 300 and the container lid 200.

[0076] In some embodiments, please refer to Figure 8, at least two sealing rings 11 are formed at the bottom of the first seal 10. The at least two sealing rings 11 are arranged at intervals in the inner and outer directions of the first seal 10. The second seal 20 is located inside the sealing ring 11. The sealing ring 11 is located at one end of the first wall 13 along the axial direction of the first wall 13. At least one sealing ring 11 straddles the first wall 13 and the second wall 14. The limiting surface 320 is an auxiliary sealing surface. The sealing ring 11 straddling the first wall 13 and the second wall 14 is in sealing contact with the auxiliary sealing surface when the locking mechanism 400 is in the locked state.

[0077] The cooking main body 300 is further formed with an auxiliary sealing surface that is arranged at a corner with the bearing surface 310. The auxiliary sealing surface and the first wall 13 are arranged opposite to each other. At least one sealing ring 11 is arranged at the corner position of the first wall 13 and the second wall 14. That is to say, the sealing ring 11 can play a sealing role between the auxiliary sealing surface and the first wall 13, and can also play a sealing role between the second sealing surface and the bearing surface 310 to improve the sealing effect.

[0078] In some embodiments, the first seal 10 includes a first sub-seal arranged oppositely in the first direction, a second sub-seal arranged oppositely in the second direction, and a third sub-seal. A third sub-seal is connected between each adjacent first sub-seal and second sub-seal. The widths of the first sub-seal and the second sub-seal are both smaller than the width of the third sub-seal.

[0079] The third sub-seal is adapted to the first corner surface 3013 and the second corner surface 323 to improve the sealing effect. During cooking, the third sub-seal is prone to deformation and air leakage. The widths of the first sub-seal and the second sub-seal are both smaller than the width of the third sub-seal, which can increase the sealing area and reduce air leakage.

[0080] In some embodiments, both the inner side surface and the outer side surface of the third sub-seal are arc-shaped, and the radius of the outer side surface of the third sub-seal is smaller than the radius of the inner side surface of the third sub-seal.

[0081] In this way, the first corner surface 3013 has a larger radius, and the contact area between the first corner surface 3013 and the third sub-seal is larger, which is beneficial to better achieve sealing; the second corner surface 323 has a smaller radius, which can extend the flow channel length at the corner, increase the flow resistance, improve the sealing performance, quickly increase the pressure inside the cooking main body 300, speed up the cooking speed, and improve the cooking effect.
