Abstract
Description
Technical Field
[0001] This utility model relates to a cooking utensil. Background Technology
[0002] Existing cooking appliances use locking mechanisms to ensure a tight seal between the lid and the inner pot.
[0003] When cooking appliances are in operation, such as during pressure cooking, the edge of the inner pot is subjected to concentrated pressure and shear force, causing deformation. Due to prolonged or repeated stress, especially under high-temperature cooking conditions, the creep phenomenon of the metal material intensifies, causing the edge to gradually bulge or sag. This not only affects the appearance but, more importantly, may lead to unstable fastening between the latch and the edge of the inner pot, creating gaps and thus affecting the sealing performance and safety of the cooking appliance.
[0004] Therefore, there is a need to provide a cooking appliance that can at least partially solve the above problems. Utility Model Content
[0005] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.
[0006] To at least partially solve the above problems, this utility model provides a cooking utensil, comprising:
[0007] The pot body, wherein a pot inner liner is provided inside the pot body, the pot inner liner comprising:
[0008] The pot body has its top recessed from bottom to top toward the central axis of the pot.
[0009] An edge is connected to the top edge of the pot body and extends outward along the radial direction of the pot body. The edge includes a body portion and a thickened portion, the thickness of which is greater than the thickness of the body portion.
[0010] A lid, which is foldably disposed on the pot body;
[0011] A fastening element is movably connected to the cover body between a locked position and an unlocked position. The fastening element is capable of engaging with the edge, and along the height direction of the cooking appliance, the projection of the fastening element engaging with the edge is located within the projection of the thickened portion.
[0012] According to the cooking appliance of this utility model, the top of the inner pot body is recessed from bottom to top towards the central axis of the inner pot. This increases the width of the edge without changing the bottom diameter of the inner pot, and the wider edge does not occupy effective cooking space. The thickened portion prevents deformation or damage to the edge due to excessive stress. The thickened portion also improves the fastening stability between the fastener and the edge of the inner pot, allowing the fastener to be more securely fastened to the edge, reducing the risk of loosening or falling off due to vibration or pressure changes. By ensuring that the projection of the fastener's engagement portion is within the projection of the thickened portion, the engagement position of the fastener and the edge is ensured to be located within the thickened portion.
[0013] Optionally, the thickened portions are arranged at circumferential intervals along the body portion.
[0014] According to this solution, by arranging the thickened parts circumferentially at intervals, the fastening strength of the fasteners is ensured while saving material costs and reducing the weight of the inner pot.

[0017] Optionally, the fastening element is provided corresponding to the clearance groove.
[0018] According to this solution, the design of the clearance groove makes the movement of the fasteners smoother and more efficient.
[0019] Optionally, a flange is provided at the radially outer end of the main body, and the flange and the thickened portion are spaced apart circumferentially along the main body; wherein,
[0020] The thickness of the flange is less than the thickness of the thickened portion, and the thickness of the flange is greater than the thickness of the main body portion.
[0021] According to this solution, by installing a flange, the strength of the unthickened portion of the pot's edge is enhanced, thereby improving the overall deformation resistance of the pot. The combination of the flange and the thickened portion optimizes stress distribution, making the pot more robust and durable.
[0022] Optionally, the thickened portion extends continuously along the circumferential direction of the body portion.
[0023] According to this solution, by continuously extending the thickened portion circumferentially, the strength of the edge can be significantly improved, thereby enhancing the overall structural strength of the pot liner.
[0024] Optionally, the width W of the thickened portion is greater than or equal to 1.5 mm.
[0025] According to this solution, by limiting this range, it is ensured that the edge has sufficient width to guarantee the engagement area with the fastener.
[0026] Optionally, the thickness T of the thickened portion is: 2mm≤T≤6mm.
[0027] According to this solution, by limiting the range, sufficient thickness is ensured to enhance structural strength, while avoiding material waste and increased manufacturing costs caused by excessive thickness.
[0028] Optionally, the thickness t of the body portion is: 1.5≤t≤4mm.
[0029] According to this plan, by limiting the scope, the basic structural requirements are met while maintaining the rational use of materials and avoiding unnecessary waste.
[0030] Optionally, the thickened portion is formed by extrusion molding or flattening.
[0031] According to this solution, both extrusion molding and flattening molding can rapidly flatten materials and improve structural strength, while significantly increasing product production speed and reducing production costs.
[0032] Optionally, the cover includes a detachable cover, and the fastener can be fastened to the top of the detachable cover and to the bottom of the edge of the inner pot.
[0033] According to this solution, the removable cover and edge can be clamped within the fastener.
[0034] Optionally, the fasteners are evenly distributed along the circumference of the cover; and / or
[0035] The number of fasteners is 2-6.
[0036] According to this solution, by setting the position and number of fasteners, it can be ensured that the contact pressure distribution between the lid and the edge of the pot body is more uniform when the lid is closed.
[0037] Optionally, the fastener can move radially along the cover to lock or release the edge.
[0038] According to this solution, the fastener can move along the radial direction of the cover, and the locking and unlocking methods are simple and flexible. Attached Figure Description

[0076] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.
[0077] This invention provides a cooking appliance. The cooking appliance of this invention can function as a rice cooker, electric pressure cooker, electric slow cooker, electric hot pot, and soy milk maker. The cooking appliance is suitable for pressure cooking.
[0078] The following will combine Figures 1 to 10 A detailed description of the cooking utensil according to this utility model is provided.
[0079] like Figure 1 and Figure 2 As shown, the cooking appliance of this utility model includes a lid 200 and a pot body 100. The pot body 100 is used for cooking food, and the lid 200 is used to cover the pot body 100. For example, the lid 200 is connected to the pot body 100 in an openable and closable manner to cover the pot body 100. When the lid 200 covers the pot body 100, a cooking space is formed between the lid and the pot body 100. Optionally, when the lid 200 covers the pot body 100, the lid 200 is sealed to the inner pot 110.
[0080] The pot body 100 is typically a rounded rectangular parallelepiped shape and has a cylindrical inner pot storage section. The pot body 100 includes an inner pot 110, which can be freely inserted into or removed from the inner pot storage section for easy cleaning. The inner pot 110 is typically made of metal and is used to hold materials to be heated, such as rice or soup. The pot body 100 also includes a middle plate 120 and a base 130. The middle plate 120 is located at the top of the pot body 100, and the base 130 is located on the sides and bottom of the pot body 100. The middle plate 120 is fixedly mounted to the base 130.
[0081] To reduce heat loss during cooking, the pot body 100 also includes a heat insulation cover 140 disposed on the outer periphery of the inner pot 110. The heat insulation cover 140 is fitted onto the outer periphery of the inner pot 110 and is located between the inner pot 110 and the base 130.
[0082] like Figures 1 to 4As shown, the cover 200 includes a top cover, a liner 210, and an inner cover. The inner cover is a removable cover 220. The top cover is located on the outermost side of the cover 200, forming the outer shell of the cover 200. The liner 210 is located below the top cover and connected to it. For example, the liner 210 can be connected to the top cover via fasteners or clips. The top cover and liner 210 constitute the upper cover assembly. The upper cover assembly is mainly used to centrally mount various functional components of the cover 200 that sense and control the working status of the cooking appliance, such as sensors. The removable cover 220 is located on the innermost side of the cover 200 and is located below the liner 210. The removable cover 220 is detachably connected to the liner 210, for example, by being mounted to the liner 210 via a removable cover mounting bracket 221, for easy cleaning and replacement. The removable cover 220 is oriented towards the cooking space; that is, when the cover 200 is in the closed position, the removable cover 220 is directly above the cooking space.
[0083] The cooking appliance also includes a locking assembly. The locking assembly includes a fastener 300, a rotating bracket 400, and a driving component. The fastener 300 is movably disposed on the lid 200. The main function of the fastener 300 is to achieve locking and unlocking between the lid 200 and the pot body 100 through its movement. In this design, the fastener 300 can engage with the edge of the inner pot 110 or the edge of the insulation cover 140. For example, in a rice cooker, the fastener 300 can engage with the edge of the inner pot 110. For example, in an electric pressure cooker, the edge of the insulation cover 140 is at least partially exposed, and the fastener 300 can engage with the edge of the insulation cover 140. For ease of explanation, the following description focuses on the fastener 300 engaging with the edge 111 of the inner pot 110.
[0084] Optionally, the fastening element 300 is connected to the rotating frame 400. Driven by the driving element, the fastening element 300 can move and lock or release the pot body 100. The rotating frame 400 allows multiple fastening elements 300 to operate simultaneously. Optionally, the fastening element 300 can move radially along the lid 200 to lock or release the edge 111 of the inner pot 110, providing a simple and flexible locking and unlocking method. In this design, the radial direction of the lid 200 refers to a straight line perpendicular to the axis from the center of the lid or the axis where the center point is located. During cooking, when it is necessary to lock the lid 200 and the pot body 100, the driving element actuates, generating a driving force. This driving force is transmitted to the fastening element 300 through the rotating frame 400, causing the fastening element 300 to move towards the center of the pot body 100. When the fastening element 300 moves to the appropriate position, it securely locks the lid 200 and the pot body 100 together. Optionally, when the fastener 300 is in the locked position, it can engage with the edge 111 of the inner pot 110. When it is necessary to open the lid 200, the drive unit drives the rotating frame 400 to move in the opposite direction, causing the fastener 300 to move away from the center of the pot body 100. When the fastener 300 moves to the appropriate position, it disengages from the pot body 100, allowing the lid 200 to open, and the fastener 300 is in the unlocked position.
[0085] The rotating frame 400 and the drive unit are positioned above the cover 210. The fastening member 300 is positioned between the cover 210 and the removable cover 220. The fastening member 300 is connected to the rotating frame 400 via a connector 340.
[0086] In some embodiments of this utility model, the fastening members 300 are evenly distributed along the circumference of the cover 200. The number of fastening members 300 is 2-6. Optionally, the number of fastening members 300 can be, but is not limited to, 2, 3, 4, 5, 6, etc., preferably 4. The even distribution of the fastening members 300 along the circumference of the cover 200, through reasonable arrangement of the number and angle, can maximize the use of the space at the edge of the cover 200, so that the fastening members 300 can meet the functional requirements without appearing crowded, ensuring that the cover 200 is subjected to uniform pressure and support when closed, thereby improving stability.
[0087] The cover 210 has a connecting groove extending along its thickness. The connecting groove moves in the same direction as the fastener 300. The connector 340 extends from below the cover 210 to above the cover 210 via the connecting groove, so that the fastener 300 is suspended from the cover 210 and moves along the connecting groove under the drive of the rotating frame 400. The suspended connection method greatly simplifies the assembly structure between the fastener 300 and the cover 210. While achieving a movable connection, the connector 340 can also serve as a transmission structure, transmitting the driving force of the drive component to the fastener 300.
[0088] As Figures 9 to 10 shown, in some embodiments of the present utility model, the fastening member 300 includes an upper fastening portion 310, a lower fastening portion 330 and an intermediate portion 320. The upper fastening portion 310 and the lower fastening portion 330 are respectively connected to the upper and lower ends of the intermediate portion 320, and both the upper fastening portion 310 and the lower fastening portion 330 extend towards the center line direction of the cooking appliance. The fastening member 300 forms a structure similar to a "匚" shape, so as to be able to form a certain clamping space. Part of the cover body 200 and part of the pot body 100 are clamped between the upper fastening portion 310 and the lower fastening portion 330. The coordinated setting of the upper fastening portion 310 and the lower fastening portion 330 provides two-way clamping for the cover body 200 and the pot body 100 in the upward and downward directions, improves the stability of the connection, and ensures good sealing performance during pressure cooking. Optionally, the upper fastening portion 310 is connected to the liner cover 210, and the lower fastening portion 330 can be selectively connected to or disengaged from the inner pot 110 to switch between the locked position and the unlocked position.
[0089] In the present utility model, the fastening member 300 in the locked position is buckled with the edge 111 of the inner pot 110. When the cooking appliance is in the cooking state, such as during pressure cooking, the edge 111 area will be subjected to concentrated pressure and shear force, and the edge 111 will deform. Due to long-term or repetitive stress, especially in a high-temperature cooking environment, the creep phenomenon of the metal material is aggravated, resulting in the edge 111 gradually bulging upward or concave downward, which not only affects the appearance, but more importantly may cause the fastening between the fastening member 300 and the edge 111 to become unstable, generating gaps, and further affecting the sealing performance and safety of the cooking appliance.
[0090] At the same time, in order to ensure the stability of the fastening between the fastening member 300 and the edge 111, the fastening part between the fastening member 300 and the edge 111 needs to be within a certain width range. A wider contact area can provide greater friction force, thereby enhancing the fastening stability and preventing loosening due to vibration or pressure change during use. The internal space of the cooking appliance is limited. An overly wide edge 111 of the inner pot 110 will occupy more space, resulting in a reduction in the volume of the cooking space.
[0091] Referring to Figures 5 to 8 , in this solution, the inner pot 110 includes an inner pot body 110 and an edge 111.
[0092] The top of the inner pot body 110 is indented from bottom to top towards the central axis of the inner pot 110. Without changing the bottom diameter of the inner pot 110, the width of the edge 11 can be increased, and the effective cooking space will not be occupied by the relatively wide edge 111.
[0093] Edge 111 connects to the top edge of the pot body 110 and extends outward in the radial direction of the pot body 110. Edge 111 includes a body portion 1111 and a thickened portion 1112, the thickness of which is greater than the thickness of the body portion 1111. Fastening member 300 can engage with edge 111, specifically with the thickened portion 1112. The thickened portion 1112 prevents deformation or damage to edge 111 due to excessive stress. The thickened portion 1112 also improves the engagement stability between fastening member 300 and the edge 111 of the pot body 110, allowing fastening member 300 to be more securely fastened to edge 111, reducing the risk of loosening or detachment due to vibration or pressure changes. When the fastener 300 is in the locked position, along the height direction of the cooking appliance, the projection of the fastener 300 and the edge 111 fastening portion is located within the projection of the thickened portion 1112. That is, the width of the lower fastening portion 330 of the fastener 300 is less than or equal to the width of the thickened portion 1112, to ensure that the fastening position of the fastener 300 and the edge 111 is located in the thickened portion 1112. If the fastener 300 moves and its axial direction is offset to a certain extent during use, the wider thickened portion 1112 can still abut against the lower fastening portion 330, thereby ensuring the stability of the fastener 300 locking.
[0094] In this design, the thickened portion 1112 is located at the radial outer end of the body portion 1111. Optionally, the thickened portion 1112 is arranged at intervals along the circumference of the body portion 1111 or extends continuously along the circumference of the body portion 1111.
[0095] The thickened portions 1112 are arranged at intervals along the circumference of the main body portion 1111. While ensuring the fastening strength of the fastening parts 300, they save material costs, reduce the weight of the inner pot 110, and are also easy to grip.
[0096] The thickened portion 1112 extends continuously along the circumference of the body portion 1111, that is, the thickened portion 1112 is continuously provided along the entire circumference of the body portion 1111 without interruption or interval. The thickened portion 1112 can significantly improve the strength of the edge 111, thereby improving the overall structural strength of the pot liner 110.
[0097] In some embodiments of this utility model, a recessed area can be designed in the middle plate 120 to form a relief groove 121. That is, the upper surface of the middle plate 120 is recessed inward along the thickness direction to form the relief groove 121. This structure makes the forming method of the relief groove 121 simple and direct.
[0098] Optionally, an additional component with a groove can be installed on the middle plate 120. This groove matches the movement trajectory of the lower latching part 330 and serves as a clearance groove 121, thereby providing clearance space when the lower latching part 330 moves. The position and shape of the clearance groove 121 can be adjusted as needed.
[0099] The clearance groove 121 provides clearance space for the fastener 300, making the locking and unlocking process of the fastener 300 smoother. The edge 111 of the inner pot 110 is located above the middle plate 120. Based on the thickened portion 1112 being spaced apart along the axial direction of the main body 1111, the thickened portion 1112 is correspondingly arranged with the clearance groove 121. The corresponding arrangement of the thickened portion 1112 and the clearance groove 121 makes the internal structure of the cooking appliance more reasonable.
[0100] In some embodiments of this utility model, the fastening member 300 is correspondingly provided with the clearance groove 121. The provision of the clearance groove 121 makes the movement of the fastening member 300 smoother and more efficient. At the same time, the clearance groove 121 can also serve as a guide structure during assembly, helping workers to quickly position the fastening member 300 and the thickened part 1112.
[0101] In some embodiments of this utility model, a flange 1113 is provided at the radially outer end of the body portion 1111. The flange 1113 and the thickened portion 1112 are spaced apart circumferentially along the body portion 1111. It can be understood that in this embodiment, the thickened portion 1112 is spaced apart circumferentially along the body portion 1111. The thickness of the flange 1113 is less than the thickness of the thickened portion 1112, and the thickness of the flange 1113 is greater than the thickness of the body portion 1111. By providing the flange 1113, the strength of the portion of the edge 111 of the pot liner 110 without the thickened portion 1112 is enhanced, thereby improving the overall deformation resistance of the pot liner 110. The coordinated arrangement of the flange 1113 and the thickened portion 1112 optimizes stress distribution, making the pot liner 110 more robust and durable.
[0102] Understandably, in some other embodiments of the present invention, the thickened portion 1112 extends continuously along the circumference of the body portion 1111, and the thickened portion 1112 forms the flange of the edge 111.
[0103] In some embodiments of this invention, the width W of the thickened portion 1112 is greater than or equal to 1.5 mm. This limitation ensures that the edge 111 has sufficient width to guarantee the engagement area with the fastening member 300.
[0104] The thickness T of the thickened portion 1112 is: 2mm ≤ T ≤ 6mm. The thickness T of the thickened portion 1112 can be, but is not limited to, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc., but is preferably 4mm. This limitation ensures sufficient thickness to enhance structural strength while avoiding material waste and increased manufacturing costs due to excessive thickness.
[0105] The thickness t of the body portion 1111 is: 1.5 ≤ t ≤ 4 mm. Optionally, the thickness t of the body portion 1111 can be, but is not limited to, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, etc., preferably 3 mm. By limiting this range, the basic structural requirements are met while maintaining the rational use of materials and avoiding unnecessary waste.
[0106] In some embodiments of this invention, the thickened portion 1112 is formed by extrusion molding or flattening. Both extrusion molding and flattening can quickly flatten the material and improve structural strength, thereby forming the thickened portion 1112. Both extrusion molding and flattening are efficient production processes that can significantly improve product production speed and reduce production costs.
[0107] Reference Figure 6 The thickened portion 1112 is formed by extrusion molding. Extrusion molding within a mold forms the thickened portion 1112 of the pot liner 110. This extrusion molding process compacts the edge 111 of the pot liner 110, increasing its thickness to form the thickened portion 1112. Before the thickened portion 1112 is formed, the edge 111 is first tightly bonded to the surface of the pot liner 110's opening. The extruded thickened portion 1112 increases the hardness of the pot liner 110, enhancing its mechanical strength and making it less prone to deformation.
[0108] Reference Figure 7 The thickened portion 1112 is formed by flattening. Understandably, the flattened thickened portion 1112 is formed by flattening the edge of the main body portion 1111 after folding it. The thickness of the thickened portion can be the same in both forming methods. Optionally, for the flattening method, the thickness of the thickened portion 1112 is approximately twice the thickness of the main body portion 1111. By providing a thickened portion 1112 with twice the thickness, the edge strength is further enhanced, and the fastening stability is improved, thus increasing user safety.
[0109] As described above, the fastening member 300 is disposed between the liner 210 and the removable cover 220. The fastening member 300 can fasten to the top of the removable cover 220 and to the bottom of the edge 111 of the inner pot 110. Specifically, the upper fastening part 310 fastens to the top of the removable cover 220, and the lower fastening part 330 fastens to the bottom of the edge 111 of the inner pot 110.
