[0041] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and do not limit the present disclosure.

[0042] In the specific embodiments, various specific technical features described can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of the various specific technical features in the present disclosure are not described again.

[0043] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related aspects. It should be understood that the orientation description "upper", "lower", "outer", "inner" are the orientation of the normal use state, which can be the left and right direction of the normal use state or not.

[0044] It should be noted that the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises... a" does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the element. "A" or "an" indicates one or more.

[0045] In the related art, cooking utensils mainly have two types of circular and square. Among them, the cooking utensils with pressure cooking function are currently generally circular. The inner container of the circular cooking utensil is limited by its shape and is mainly suitable for small-volume or regular-shaped food materials, such as cut vegetables, meat blocks, etc. For large-volume and long-strip-shaped food materials, such as whole chicken, duck, fish, large beef steaks, etc., the circular cooking utensil is not suitable. Since the square cooking utensil has a frame with edges and corners, especially if the sealing ring cannot effectively fit the combined position of the two edges, a complete sealing problem may occur. The sealing ring is lifted up along with the container cover under the pressure in the cooking cavity, which reduces the sealing between the sealing ring and the cooking main body. Therefore, the square cooking utensil is basically pressureless, such as slow cooker and electric chafing dish. The cooking time is relatively long, and the square cooking utensil can meet more cooking scenes and be suitable for different types of food materials. The cooking without sealing cannot fully extract the nutrients of the food, which leads to nutrient loss.

[0046] Therefore, referring to FIGS. 1-2, the present disclosure provides a cooking utensil 1000. The present disclosure also provides a cooking main body 300, referring to FIGS. 3-5. 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 oppositely arranged along a first direction, a second wall surface 3012 oppositely arranged 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 a circular arc surface. The limiting surface 320 includes a first sub-surface 321 oppositely arranged along the first direction, a second sub-surface 322 oppositely arranged 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 a circular arc surface. The radius of the first corner surface 3013 is greater than the radius of the second corner surface 323. In the figures, X represents the first direction, and Y represents the second direction.

[0047] The cooking utensil 1000 has a square container cover 200 and a cooking main body 300 for accommodating food materials, the container cover 200 is covered on the cooking main body 300 to form a closed cooking cavity 300a, and a sealing ring 100 is arranged between the container cover 200 and the cooking main body 300 to seal, so that the cooking utensil 1000 can quickly increase the temperature and pressure in the cooking main body 300 during cooking, and improve the cooking efficiency.

[0048] The cooking utensil 1000 generates steam in the cooking cavity 300a of the cooking main body 300 during cooking, and the steam gradually increases, and the pressure in the cooking cavity 300a of the cooking main body 300 gradually increases to lift the container cover 200, and the sealing effect of the sealing ring 100 is weakened. In order to improve the sealing between the sealing ring 100 and the cooking main body 300, the cooking main body 300 provided by the embodiment of the present disclosure has a first corner face 3013 with a radius greater than that of a second corner face 323, which can cooperate with the sealing ring 100 to improve the sealing effect during cooking.

[0049] Specifically, when not yet cooking, the sealing ring 100 is pressed on the bearing surface 310, and when the amount of steam generated by heating at the initial stage of cooking is not enough to lift the container cover 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, the steam cannot flow out from between the sealing ring 100 and the cooking main body 300, so that as the heating time of the cooking main body 300 increases, the inside of the cooking main body 300 can be kept in a sealed state, and the pressure increases rapidly.

[0050] As the heating time of the cooking main body 300 further increases, under the action of the internal accumulated pressure, two-stage sealing can be achieved between the bearing surface 310 and the side wall surface 301 and the sealing ring 100, which can achieve two-stage sealing effect on the cooking main body 300 during cooking. And the first corner face 3013 has a larger radius, so that the contact area of the first corner face 3013 and the sealing ring 100 is larger, which is beneficial to better realize sealing; the second corner face 323 has a smaller radius, which can prolong the length of the flow channel at the corner, increase the flow resistance, improve the sealing, make the pressure in the cooking main body 300 increase rapidly, speed up the cooking speed, and improve the cooking effect.

[0051] In some embodiments, the radius of the first corner face is greater than or equal to 40 mm, and the radius of the first corner face 3013 is less than or equal to 100 mm.

[0052] The radius of the first corner face 3013 refers to the radius of the circular arc line intersected by the plane perpendicular to the up-down direction and the first corner face 3013.

[0053] 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.

[0054] The radius of the second corner surface 323 refers to the radius of the circular arc line intersected by the plane perpendicular to the up-down direction and the second corner surface 323.

[0055] In some embodiments, the cooking main body 300 comprises a containing device, and the cooking cavity 300a, the bearing surface 310, and the limiting surface 320 are all formed on the containing device.

[0056] The containing device can be an inner container 340.

[0057] In other embodiments, the containing device is an inner container 340, and the cooking cavity 300a further comprises an outer pot 330, and the inner container 340 is installed in the outer pot 330. For example, referring to FIG. 1, the cooking main body 300 can comprise an outer pot 330 and an inner container 340, the outer pot 330 is used to install the inner container 340 and install a heating device used to heat the inner container 340. The outer pot 330 is formed with a mounting cavity, the inner container 340 is located in the mounting cavity of the outer pot 330, and the inner container 340 is formed with the cooking cavity 300a used to contain food materials.

[0058] In some embodiments, the bearing surface 310 is a plane.

[0059] In this way, the fitting effect of the bearing surface 310 and the sealing ring 100 can be improved, the sealing performance is improved, the pressure in the cooking cavity 300a is quickly increased, the cooking speed is accelerated, and the cooking effect is improved.

[0060] 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 a circular arc, the shape of the outer edge line of the bearing surface 310 is a circular arc, the radius of the inner edge line is greater than the radius of the outer edge line, and the bearing surface 310 is a plane.

[0061] The radius of the inner edge line of the bearing surface 310 is greater than the radius of the outer edge line, which helps to improve the sealing effect of the sealing ring 100 of the cooking main body 300, the length of the flow channel at the corner can be extended, the flow resistance is increased, the pressure in the cooking main body 300 is quickly increased, the cooking speed is accelerated, and the cooking effect is improved.

[0062] 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 at the corner of the bearing surface 310 is a circular arc, the shape of the outer edge line at the corner of the bearing surface 310 is a circular arc, the radius of the inner edge line is greater than the radius of the outer edge line, and the bearing surface 310 is a plane.

[0063] Thus, the radius of the inner edge line at the corner of the bearing surface 310 is greater than the radius of the outer edge line at the corner, which helps to improve the sealing effect of the sealing ring 100 of the cooking body 300, can prolong the flow path length at the corner, increase the flow resistance, make the pressure in the cooking body 300 quickly rise, speed up the cooking speed, and improve the cooking effect.

[0064] In some embodiments, referring to FIGS. 6-8, the cooking utensil 1000 includes the sealing ring 100, the container cover 200, and the cooking body 300 of any of the above embodiments; the sealing ring 100 is arranged on the cooking body 300; the container cover 200 is connected with the sealing ring 100; the locking mechanism 400 is movably installed on the cooking body 300, and the locking mechanism 400 is used to lock or unlock the cooking body 300 and the container cover 200, and 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.

[0065] The cooking body 300 and the container cover 200 can be locked by the locking mechanism 400, and the possibility that the container cover 200 is lifted up to affect the sealing effect inside the cooking cavity 300a can be reduced in the initial stage of cooking by the locking mechanism 400.

[0066] For example, the locking mechanism 400 and the cooking body 300 clamp the container cover 200 in the up-down direction to lock the cooking body 300 and the container cover 200.

[0067] The locking mechanism 400 can limit the position of the container cover 200, for example, press the upper end of the container cover 200 in the up-down direction, so that the container cover 200 presses the sealing ring 100 on the bearing surface 310.

[0068] In some embodiments, referring to FIG. 8, the sealing ring 100 includes the first sealing member 10 and the second sealing member 20. The projection area of the first sealing member 10 along the axial direction is a square ring, and the first sealing member 10 is used to seal with the bearing surface 310 of the cooking utensil 1000; the second sealing member 20 is connected to the inner side of the first sealing member 10, and the second sealing member 20 is arranged around the first sealing member 10 along the circumferential direction, and the second sealing member 20 at least partially protrudes from one side of the first sealing member 10 along the axial direction, and the second sealing member 20 is used to seal with the side wall surface 301 of the cooking cavity 300a of the cooking utensil 1000.

[0069] Here, the axial direction refers to the cross-sectional direction perpendicular to the circumferential direction of the square ring.

[0070] The first sealing member 10 is a square ring arranged around the circumference of the container cover 200, and is adapted to the shape of the square container cover 200 to achieve a sealing effect. The first sealing member 10 can achieve a sealing effect between the cooking main body 300 and the sealing cover in the up-down direction, and the second sealing member 20 can seal the cooking main body 300 in the horizontal direction.

[0071] Specifically, referring to FIG. 8, when not yet cooking, the first sealing member 10 is pressed on the bearing surface 310, and the second sealing member 20 is attached to 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. In the initial stage of cooking, when the amount of steam generated after heating cooking is not enough to lift the container cover 200, the first sealing member 10 is pressed on the bearing surface 310 of the cooking main body 300 by gravity or an external locking mechanism 400 to achieve a sealing effect between the cooking main body 300 and the sealing cover. At this time, even if steam leaks from between the second sealing member 20 and the cooking main body 300, it cannot further leak from between the first sealing member 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 be kept in a sealed state, and the pressure rapidly increases.

[0072] As the heating time of the cooking main body 300 further increases, the second sealing member 20 can be sealed against the side wall of the cooking main body 300 under the action of the pressure accumulated inside. Thus, the first sealing member 10 and the second sealing member 20 can achieve a two-stage sealing effect on the cooking main body 300 during cooking, rapidly increase the pressure inside the cooking main body 300, speed up the cooking speed, and improve the cooking effect.

[0073] In some embodiments, referring to FIG. 8, the bottom of the first sealing member 10 is formed with at least two sealing rings 11, and the at least two sealing rings 11 are arranged in the inner-outer direction of the first sealing member 10, and the second sealing member 20 is located on the inner side of the sealing ring 11.

[0074] The inner direction of the first sealing member 10 refers to the direction towards the cooking cavity 300a inside the cooking main body 300, and the outer direction of the first sealing member 10 refers to the direction away from the cooking cavity 300a inside the cooking main body 300.

[0075] By providing the sealing ring 11, the contact area of the sealing ring 11 and the bearing surface 310 of the cooking main body 300 can be reduced, and the sealing effect can be improved. Moreover, the multiple sealing rings 11 can achieve a multiple sealing effect, and further improve the sealing effect.

[0076] In some embodiments, referring to FIG. 8, the first sealing member 10 has a target surface 12 on one side of the first sealing member 10 in the axial direction of the first sealing member 10, and the sealing ring 11 protrudes from the target surface 12, and the maximum distance between the sealing ring 11 and the target surface 12 in the axial direction of the first sealing member 10 is less than the maximum distance between the second connecting member and the target surface 12.

[0077] The maximum distance between the second sealing member 20 and the target surface 12 refers to the distance between the bottom end of the second sealing member 20 in the up-down direction and the target surface 12. The length of the second sealing member 20 in the up-down direction is greater than the thickness of the sealing ring 11 in the up-down direction, so that the second sealing member 20 can be fitted with at least part of the side wall of the cooking main body 300 to achieve a sealing effect.

[0078] In some embodiments, referring to FIG. 8, the first sealing member 10 includes a first wall 13 and a second wall 14. The projection area of the first wall 13 in the axial direction of the first wall 13 is in the shape of a square ring; the second wall 14 is located on the inner side of the first wall 13, and the opposite ends of the first wall 13 are connected with the second wall 14, and the first wall 13 and the second wall 14 surround to form a receiving cavity 10a for accommodating the edge of the container cover 200. The projection area of the receiving cavity 10a in the axial direction of the first wall 13 is in the shape of a square ring, the second sealing member 20 is connected with one of the second walls 14, and the second sealing member 20 is located on the side corresponding to the second wall 14 away from the receiving cavity 10a in the axial direction of the first wall 13.

[0079] The first wall 13 and the second wall 14 are arranged to form the receiving cavity 10a towards the cooking cavity 300a in the cooking main body 300, and the outer periphery of the container cover 200 is located in the receiving cavity 10a. In this way, the sealing member and the container cover 200 can be fitted to enable the sealing member to be closely fitted on the surface of the container cover 200 to achieve a sealing effect between the cooking main body 300 and the container cover 200.

[0080] In some embodiments, referring to FIG. 8, the bottom of the first sealing member 10 is formed with at least two sealing rings 11, and the at least two sealing rings 11 are arranged in the inner-outer direction of the first sealing member 10. The second sealing member 20 is located on the inner side of the sealing ring 11, the sealing ring 11 is located at one end of the first wall 13 in the axial direction of the first wall 13, and at least one sealing ring 11 is arranged across the first wall 13 and the second wall 14. The limiting surface 320 is an auxiliary sealing surface, and the sealing ring 11 arranged across 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.

[0081] The cooking main body 300 is further formed with an auxiliary sealing surface arranged at a corner of the bearing surface 310, and the auxiliary sealing surface is arranged opposite to the first wall 13. The at least one sealing ring 11 is arranged at the corner position of the first wall 13 and the second wall 14, that is, 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, so as to improve the sealing effect.

[0082] In some embodiments, referring to FIG. 2, the first sealing member 10 includes first sub-sealing members 101 arranged opposite to each other along a first direction, second sub-sealing members 102 arranged opposite to each other along a second direction, and third sub-sealing members 103 connected between each adjacent first sub-sealing member 101 and second sub-sealing member 102, and the width of the first sub-sealing member 101 and the width of the second sub-sealing member 102 are both less than the width of the third sub-sealing member 103.

[0083] The third sub-sealing member 103 is adapted to the first corner surface 3013 and the second corner surface 323, so as to improve the sealing effect. In the cooking process, the third sub-sealing member 103 is prone to deformation and air leakage. The width of the first sub-sealing member 101 and the width of the second sub-sealing member 102 are both less than the width of the third sub-sealing member 103, so as to increase the sealing area and reduce air leakage.

[0084] In some embodiments, the inner side surface and the outer side surface of the third sub-sealing member 103 are both arc-shaped, and the radius of the outer side surface of the third sub-sealing member is less than the radius of the inner side surface of the third sub-sealing member 103.
