Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and more specifically to an inner lining component and a cooking utensil. Background Technology

[0002] Existing cooking appliances with top heating functions typically have a high-temperature resistant insulation component between the top heater and the lid to prevent heat transfer to the plastic lid and causing deformation or damage. This insulation component, needing to withstand high temperatures, is usually made of high-temperature resistant materials such as PET or PBT. The insulation component is detachably connected to the inner lining using clips or other methods. However, while high-temperature resistant materials possess excellent heat resistance, they are generally hard, brittle, and have poor toughness; therefore, the clips are prone to breakage during assembly or disassembly.

[0003] Therefore, there is a need to provide a lining component and a cooking appliance to at least partially solve the above problems. Utility Model Content

[0004] 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.

[0005] To at least partially solve the above problems, the first aspect of this utility model provides an inner liner assembly, comprising: The inner lining body is provided with at least one hook; A heat insulation component is provided with a first mounting hole corresponding to the hook, the hook being located within the first mounting hole and hooked to the heat insulation component; and An insulation board is installed on the side of the insulation component away from the inner lining body, and the insulation board is provided with heating elements.

[0006] According to the first aspect of the present invention, the inner lining assembly achieves direct fixation between the inner lining body and the heat insulation component through the hook and the first mounting hole, which is simple and reliable. By setting the hook on the inner lining body, it is possible to avoid using a material with poor toughness directly for the hook, and the hook is not easy to break during assembly or disassembly, thereby solving the problem of easy damage to the heat insulation component clip.

[0007] Optionally, the fastening direction of the hook is toward the center of the lining body.

[0008] According to this scheme, a self-locking structure is formed, which enhances the stability of the connection.

[0009] Optionally, the hook is integrally formed with the inner lining body.

[0010] According to this solution, the hooks are made of materials with poor toughness, which avoids the need for direct use, and the solution is also easy to manufacture.

[0018] According to this scheme, within a wall thickness range of 0.6mm to 1.2mm, its toughness can be fully utilized, and the wall thickness is sufficient to withstand working stress, but not so thick that the material becomes brittle.

[0019] Optionally, the engagement amount of the hook is 1.2mm to 2.5mm.

[0020] According to this solution, within a fastening range of 1.2mm to 2.5mm, the hook can provide sufficient retaining force to prevent loosening; at the same time, the hook can be pried open relatively easily with the help of tools, achieving non-destructive disassembly.

[0021] Optionally, the width of the hook is 5mm to 10mm.

[0022] According to this solution, within a width range of 5mm to 10mm, the hook can be prevented from twisting or tilting laterally under force, ensuring uniform force distribution.

[0023] Optionally, the heat insulation member has a first guide surface at the periphery of the first mounting hole for guiding the hook to engage.

[0024] According to this plan, the hooks are guided to engage, reducing assembly resistance.

[0025] Optionally, the hook is provided with a second guide surface for engaging with the hook.

[0026] According to this plan, the hooks are guided to engage, reducing assembly resistance.

[0027] Optionally, the first guide surface is disposed on the periphery of the side of the first mounting hole facing the liner.

[0028] According to this solution, the guide hook gradually approaches the first mounting hole from top to bottom, easily passing through the first mounting hole.

[0029] Optionally, the first guide surface is disposed on the periphery of the first mounting hole near the center of the liner.

[0030] According to this solution, the guide hook can easily pass through the first mounting hole when installed from top to bottom.

[0031] Optionally, one of the inner lining body and the heat insulation component is provided with at least one screw hole, and the other of the inner lining body and the heat insulation component is provided with at least one screw post. The screw post is correspondingly provided with the screw hole and is fixed by screws.

[0032] According to this solution, even if individual hooks break during assembly, disassembly, or use, the components can still remain securely connected through the remaining hooks and screw system.

[0033] Optionally, when the heat insulation component is installed into the inner lining body, the screw holes and the hooks are distributed circumferentially along the heat insulation component.

[0034] According to this solution, the combination of screws and hooks ensures the flatness of the connection and the uniformity of force distribution.

[0035] Optionally, the heat insulation element is provided with a second mounting hole; The insulation board is provided with clips corresponding to the second mounting hole; The locking pin is located in the second mounting hole and hooked to the heat insulation component.

[0036] According to this solution, a reliable connection between the insulation board and the thermal insulation component can be achieved.

[0037] Optionally, the first mounting hole and the second mounting hole are distributed at intervals along the circumference of the heat insulation member.

[0038] According to this plan, the inner lining body can be smoothly engaged with the insulation component, and the insulation board can also be smoothly assembled onto the insulation component.

[0049] 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.

[0050] Reference Figure 1This utility model provides a cooking appliance. The cooking appliance according to this application can be a rice cooker, electric pressure cooker or other cooking appliances with electromagnetic heating function, and in addition to the function of cooking rice, the cooking appliance can also have various functions such as cooking porridge.

[0051] The cooking appliance of this utility model includes a lid 2 and a pot body 1. The pot body 1 is used for cooking food, and the lid 2 is used to cover the pot body 1. When the lid 2 covers the pot body 1, a cooking space is formed between the lid 2 and the pot body 1.

[0052] The pot body 1 is typically a rounded rectangular parallelepiped shape and has a cylindrical inner pot storage section. The pot body 1 includes the inner pot, which can be freely placed into or removed from the inner pot storage section for easy cleaning. The inner pot is usually made of metal and is used to hold materials to be heated, such as rice or soup. The lid 2 has a shape that substantially corresponds to the pot body 1. The lid 2 is closable and hinged onto the pot body 1; specifically, it is pivotally connected to the pot body 1 via a pivot axis and can freely pivot between a closed and open position relative to the pot body 1 about the pivot axis, facilitating the closing and opening of the pot body 1.

[0053] Reference Figure 2 , Figure 7 and Figure 8 The cover 2 includes a faceplate 3 and an inner liner assembly. The faceplate 3 is located on the outermost side of the cover 2 to form the outer shell of the cover 2. The inner liner assembly is located below the faceplate 3 and is connected to the faceplate 3. For example, the inner liner assembly can be connected to the faceplate 3 by fasteners or snap-fits.

[0054] It should be noted that the directional terms used in this article to describe the various parts and components of the cooking appliance, such as "up and down," "left and right," and "front and back," are relative to the cooking appliance when it is placed horizontally and upright with the lid 2 closed onto the pot body 1. When the cooking appliance is placed on a surface, the direction facing the surface is considered downward, and the direction away from the surface is considered upward. Understandably, when the lid 2 is open, the approximate front-back direction of the lid 2 is the up and down direction, the approximate up and down direction of the lid 2 is the back-forward direction, and the approximate left-right direction of the lid 2 is the left and right direction. Unless otherwise specified, the up and down, front-back, and left and right directions are generally defined from the user's perspective when the pot body 1 is upright and facing normally. The side closer to the user is the front, and the side farther from the user is the back. When the user is facing the pot body 1 normally, the user's left side corresponds to the left side of the pot body 1, and the user's right side corresponds to the right side of the pot body 1. In addition, unless otherwise specified, the "inner" in directional terms such as "inward", "outward", "towards", "inner side", "outer side", etc., refers to the area close to the center of the pot body 1, and the "outer" refers to the area far from the center of the pot body 1.

[0055] In the description of this application, it should be understood that the terms "upper", "lower", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship when the product is in normal use (i.e., when the lid is closed). They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0056] Cooking appliances typically heat from the bottom, resulting in a significant temperature difference between the bottom and top of the rice or food during cooking. This can easily lead to the bottom becoming mushy while the top remains undercooked, or the rice being soft on top and hard on the bottom, resulting in an unpleasant texture.

[0057] Reference Figures 2 to 7 This design incorporates a heating element 31 within the lid 2 to achieve simultaneous heating from both sides, thereby transferring heat to the food more quickly and shortening cooking time to some extent. Simultaneously, the top heating element keeps the inner lining components at a high temperature, preventing water vapor from condensing on the inner wall of the lid, effectively reducing condensation dripping and resulting in dry and delicious cooked rice.

[0058] To reduce the thermal impact of the heating element 31 on the cover 3 and prevent the cover 3 from deforming due to high temperature or causing burns to the user, this solution includes a heat insulation component 20 between the heating element 31 and the cover 3 in the inner lining assembly. This heat insulation component 20 is made of high-temperature resistant plastic (such as PET, PBT, etc.) and can effectively block the direct transfer of heat, thereby protecting the cover 3 of the cover body 2 and other internal electronic components.

[0059] The thermal insulation component 20 can be detachably connected to the insulation component using a method such as a snap-fit. The thermal insulation component 20 can also be detachably connected to the inner lining body 10 using a method such as a snap-fit. During installation, the insulation component and the thermal insulation component 20 can be connected together first to form a single assembly. Then, the thermal insulation component 20 is connected to the inner lining body 10, allowing the assembly formed by the insulation component and the thermal insulation component 20 to be installed on the inner side of the lining. This embodiment facilitates the installation of the thermal insulation component 20 onto the lining, improving assembly efficiency and reducing manufacturing costs.

[0060] However, the thermal insulation component 20 is typically made of high-temperature resistant materials such as PET and PBT. While these materials possess excellent heat resistance, they are generally hard, brittle, and have poor toughness. When hooks 11 for assembly are installed on such thermal insulation components 20, these hooks 11 are prone to breakage during assembly or disassembly. Once the hooks 11 break, the entire thermal insulation component 20 becomes difficult to secure reliably, often resulting in component scrap and high production costs.

[0061] This design places the hook 11 on the inner lining body 10. Optionally, the inner lining body 10 is made of high-toughness plastics such as PP or PE. Optionally, the hook 11 is integrally molded with the inner lining body 10. The hook 11 is made of high-toughness plastics such as PP or PE. By placing the hook 11 on the inner lining body 10, this design avoids using a material with poor toughness directly for the hook 11. Furthermore, using a high-toughness material for the hook 11 further solves the problem of easy breakage.

[0062] The inner lining assembly also includes a heat insulation element 20 and a heat insulation board 30. With the cover 2 closed, the heat insulation board 30 is located below the inner lining body 10, and the heat insulation element 20 is located between the inner lining body 10 and the heat insulation board 30 to separate the inner lining body 10 and the heat insulation board 30 from direct contact, thereby preventing the heat from the heating element 31 from being transferred to the inner lining body 10, thus reducing the risk of the inner lining body 10 overheating, preventing the inner lining body 10 from deforming or melting due to heat, and also reducing the impact of the heating element 31 on the cover 3.

[0063] The inner lining body 10 is provided with at least one hook 11. Optionally, a plurality of hooks 11 are spaced apart around the periphery of the inner lining body 10 and are distributed approximately evenly around a circle.

[0064] The heat insulation component 20 can be a closed annular member with a hollow structure, the shape of which is adapted to the shape of the inner lining body 10. The heat insulation component 20 is provided with a first mounting hole 21 corresponding to the hook 11, the hook 11 being located within the first mounting hole 21 and hooked to the heat insulation component 20. Through the hook-and-hook connection between the hook 11 and the first mounting hole 21, direct fixation between the inner lining body 10 and the heat insulation component 20 is achieved, resulting in a simple and reliable structure, reducing the number of parts and assembly complexity. Correspondingly, the first mounting holes 21 are spaced apart along the circumference of the heat insulation component 20, corresponding to the hook 11. By engaging the first mounting hole 21 with the hook 11, evenly distributed fixing points are formed in the circumferential direction of the heat insulation component 20, ensuring that the inner liner body 10 and the heat insulation component 20 can fit tightly and flatly without local warping or gaps; at the same time, it also ensures uniform force distribution, avoiding excessive force concentration that could cause individual hooks 11 to be stretched and deformed due to excessive stress, thus ensuring the flatness and long-term structural stability of the component after assembly.

[0065] Optionally, the hook 11 is positioned with its snapping direction facing the center of the inner lining body 10. When the hook 11 is snapped in, the locking force it generates is centripetal, thus forming a self-locking structure, greatly enhancing the stability of the connection and effectively preventing loosening due to vibration or force during use. Optionally, when the hook 11 is hooked to the heat insulation member 20, the upper surface of the hook 11 abuts against the lower surface of the heat insulation member 20. To ensure a firm and reliable connection, both the upper surface of the hook 11 and the lower surface of the heat insulation member 20 can be flat.

[0066] Optionally, the heat insulation member 20 is provided with a first guide surface 22 for guiding the hook 11 to engage at the periphery of the first mounting hole 21. Optionally, the first guide surface 22 is located on the periphery of the first mounting hole 21 facing the inner liner body 10. Optionally, the first guide surface 22 is located on the periphery of the first mounting hole 21 near the center of the inner liner body 10. Exemplarily, an upwardly extending protrusion is provided above the heat insulation member 20 and on the side of the first mounting hole 21 near the center of the inner liner body 10. The side of the protrusion facing away from the center of the inner liner body 10 is an inclined slope that gradually approaches the first mounting hole 21 from top to bottom. When the hook 11 is installed from top to bottom, it can first contact the first guide surface located on the outer periphery of the first mounting hole 21, and be guided by the first guide surface to gradually approach the first mounting hole 21 from top to bottom. The hook 11 continues to descend, thereby easily and without interference passing through the first mounting hole 21.

[0067] Optionally, the hook 11 is provided with a second guide surface 12 for engaging with the guide hook 11. Exemplarily, this includes a chamfer or rounded edge at the head of the hook 11. Optionally, the hook 11 is a wedge shape with a narrowed head.

[0068] Based on the above embodiments, the first guide surface 22 cooperates with the second guide surface 12 to further reduce assembly resistance, so as to facilitate rapid assembly.

[0069] Optionally, the hook 11 is spaced apart from the heating element 31 to prevent heat from being transferred to the hook 11 through solid conduction, the most direct and efficient method.

[0070] Optionally, the height H of the hook 11 is 8mm to 12mm. The height H can be, but is not limited to, 8mm, 9mm, 10mm, 11mm, and 12mm. Within the height range of 8mm to 12mm, the hook 11 has a sufficiently long lever arm to undergo elastic deformation, allowing it to smoothly slide over the engagement point during assembly and evenly distribute the deformation stress across the entire arm, avoiding stress concentration. If the height of the hook 11 is too small, the elastic arm is too short, resulting in excessive rigidity. During assembly, greater force is required to deform it. If the height of the hook 11 is too large, the elastic arm is too long. Although assembly is easier, the gripping force of the hook 11 is insufficient. Under vibration or external force, the hook 11 may detach on its own.

[0071] Optionally, the wall thickness D of the hook 11 is 0.6mm to 1.2mm. The wall thickness D can be, but is not limited to, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, and 1.2mm. Within the wall thickness range of 0.6mm to 1.2mm, high-toughness plastics such as PP can fully utilize their toughness. The wall thickness is sufficient to withstand working stress, but not so thick that it makes the material brittle. If the wall thickness is too thin, it is prone to deformation and cannot meet the basic fixing function. If the wall thickness is too thick, the rigidity is too high, making assembly difficult and wasting material.

[0072] Optionally, the engagement depth L of the hook 11 is 1.2mm to 2.5mm. The engagement depth L can be, but is not limited to, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2.0mm, 2.2mm, and 2.5mm. Within the engagement depth range of 1.2mm to 2.5mm, the hook 11 provides sufficient retaining force to prevent loosening; it can also be pried open relatively easily with the aid of tools, achieving non-destructive disassembly. If the engagement depth is too small, slight vibration or thermal expansion and contraction may cause the hook 11 to slip out of the engagement surface. If the engagement depth is too large, assembly becomes difficult, and non-destructive disassembly is almost impossible during maintenance; forced disassembly will inevitably lead to the breakage of the hook 11.

[0073] Optionally, the width W of the hook 11 is 5mm to 10mm. The width W can be, but is not limited to, 5mm, 6mm, 7mm, 8mm, 9mm, and 10mm. Within the width range of 5mm to 10mm, the hook 11 can be prevented from lateral twisting or tilting under load, ensuring uniform force distribution. If the width is too small, lateral instability is likely, and twisting may occur under load. If the width is too large, material is wasted.

[0074] To further ensure the stability of the lining assembly, this solution also includes screw fixing in addition to the elastic hook 11 connection.

[0075] In some embodiments, at least one upwardly protruding screw post 23 is provided on the surface of the heat insulation member 20 facing the inner liner body 10. The screw post 23 may be hollow with internal threads, or it may be solid and made of a self-tapping screw. Screw holes 13 are provided at positions corresponding to the screw post 23 on the inner liner body 10. During assembly, the hook 11 is first engaged, and then the screw is screwed into the screw post 23 of the heat insulation member 20 from above the inner liner body 10 to lock the two together.

[0076] In other embodiments, a downwardly protruding screw post 23 is provided on the surface of the inner liner body 10 facing the heat insulation member 20. A screw hole 13 is provided at the position corresponding to the screw post 23 on the heat insulation member 20. During assembly, after engaging the hook 11, the screw is screwed in from below the heat insulation member 20, passing through the screw hole 13 of the heat insulation member 20, and into the screw post 23 of the inner liner body 10.

[0077] According to this solution, even if individual hooks 11 break during assembly, disassembly, or use, the components can still be securely connected by the remaining hooks 11 and screw system.

[0078] One of the inner lining body 10 and the heat insulation component 20 is provided with at least one screw hole 13, and the other of the inner lining body 10 and the heat insulation component 20 is provided with at least one screw post 23. The screw post 23 is correspondingly provided with the screw hole 13 and is fixed by screws.

[0079] Optionally, when the thermal insulation element 20 is installed into the inner liner body 10, the screw holes 13 and the hooks 11 are spaced apart circumferentially along the thermal insulation element 20. This ensures that the fastening points are evenly stressed on the mating surfaces of the inner liner body 10 and the thermal insulation element 20. The hooks 11 provide circumferential, centripetal locking force, while the screws provide vertical clamping force, ensuring the flatness of the connection and the uniformity of force distribution, further protecting the hooks 11 from breakage due to localized overload.

[0080] In this design, the insulation board 30 is installed on the side of the heat insulation component 20 opposite to the inner liner body 10, i.e., below the heat insulation component 20. In other words, the insulation board 30 can be installed from below the inner liner body 10 via the heat insulation component 20. The heating element 31 is installed above the insulation board 30, i.e., in the space between the inner liner body 10 and the insulation board 30. The inner liner body 10 and the insulation board 30 provide a barrier that relatively isolates the heating element 31 from the cooking cavity and the external environment. During assembly, the heating element 31 can be first fixed to the insulation board 30 by adhesive or other means, and then installed from below onto the heat insulation component 20.

[0081] Optionally, the heat insulation component 20 is provided with a second mounting hole 24; the insulation board 30 is provided with a locking foot 32 corresponding to the second mounting hole 24; the locking foot 32 is located in the second mounting hole 24 and hooked to the heat insulation component 20. During assembly, the locking foot 32 on the insulation board 30 is aligned with the second mounting hole 24 on the heat insulation component 20. The locking foot 32 is pushed in vertically until it completely passes through the second mounting hole 24. After the locking foot 32 passes through the second mounting hole 24, the end of the locking foot 32 is bent to one side at a 90-degree angle or a certain angle using a tool or specific fixture. The bent portion of the locking foot 32 is firmly hooked onto the surface of the heat insulation component 20 facing away from the insulation board 30.

[0082] Optionally, the first mounting hole 21 and the second mounting hole 24 are distributed at intervals along the circumference of the heat insulation member 20. That is, the fastening point for fixing the inner lining body 10 (first mounting hole 21) and the point for fixing the insulation board 30 (second mounting hole 24) are staggered in the circumferential direction of the heat insulation member 20, thereby ensuring that the inner lining body 10 can be smoothly engaged with the heat insulation member 20, while the insulation board 30 can also be smoothly assembled onto the heat insulation member 20.
