Description

Technical Field

[0001] This utility model relates to cooking utensils. Background Technology

[0002] The steam valve is a crucial component ensuring safety during cooking. It is typically installed on the lid of the appliance, and a seal is required between the valve and the lid to ensure proper operation. During assembly, the valve's protrusion is passed through the inner hole of the sealing ring, utilizing the seal's malleability to secure it and prevent detachment, while also allowing for easy disassembly and cleaning. In the radial direction of the lid, the seal is usually clamped between the lid and the steam valve. Since silicone seals are generally more difficult to dimensionally control than plastic seals, they are prone to larger errors, affecting the sealing effect and leading to problems such as the steam valve easily detaching or being difficult to disassemble and install.

[0003] Therefore, there is a need to provide a cooking appliance that can 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, this utility model provides a cooking utensil, comprising:

[0006] The pot body; and

[0007] A lid body, which is foldably disposed on the pot body to form a cooking space between the lid body and the pot body, is provided with a mounting part, which has a communication hole for connecting the cooking space with the outside, and a limiting part disposed on the inner peripheral wall of the communication hole.

[0008] A steam valve, wherein the steam valve is installed into the communicating hole, and at least a portion of the steam valve is limited above the limiting portion; and

[0009] A sealing element is located above the steam valve, the sealing element is sealed to the mounting portion, and the bottom of the sealing element abuts against the steam valve.

[0010] For the cooking appliance according to the present utility model, the steam valve is axially limited between the seal and the limiting portion, so that it is restricted during installation, ensuring that the steam valve is stably installed in the working position, reducing the problem of seal failure caused by the dimensional error of the silicone seal, and thus improving the overall sealing effect. This solution reduces the dependence on the dimensional accuracy of the seal through structural optimization, so that a more general manufacturing process can be adopted, reducing production costs and improving product consistency.

[0011] Optionally, the limiting portion protrudes from the inner peripheral wall of the communication hole; wherein,

[0012] The limiting portion includes a first limiting portion extending along the circumferential direction of the communication hole, and the steam valve abuts against the upper surface of the first limiting portion.

[0013] According to this solution, the steam valve abuts above the first limiting portion, so that the steam valve can be accurately fixed in the predetermined position during installation, preventing it from moving downward in the axial direction.

[0014] Optionally, the limiting portion further includes a second limiting portion extending along the axial direction of the communication hole, the steam valve has a locked position and an unlocked position, and when the steam valve is in the locked position, the second limiting portion abuts against the steam valve.

[0015] According to this solution, the second limiting portion is used to limit the circumferential rotation of the steam valve, ensuring that the steam valve can always remain in the predetermined working position. The second limiting portion can also be used as a reference during the installation of the steam valve, ensuring that the steam valve is installed in place and improving product consistency.

[0016] Optionally, a notch is formed by recessing the outer peripheral edge of the steam valve inward in the radial direction, and the notch is for the limiting portion to pass through.

[0017] According to this solution, the setting of the notch simplifies the installation process of the steam valve, and the steam valve can effectively connect with the limiting portion through the notch.

[0018] Optionally, the length of the notch in the circumferential direction is greater than the length of the first limiting portion in the circumferential direction.

[0019] According to this solution, the notch allows the first limiting portion to pass through, so that the steam valve can be installed into the communication hole from the lower end of the communication hole.

[0020] Optionally, the range of the length L of the first limiting portion in the circumferential direction is: 1 / 8D < L < 1 / 6D, where D is the circumference of the inner peripheral wall of the communication hole.

[0021] According to this solution, by limiting this range, the first limiting part is ensured to have sufficient length to ensure its strength to support the steam valve, while avoiding material waste and increased manufacturing costs caused by excessive length.

[0022] Optionally, the height H of the second limiting part is in the range of: H>2mm.

[0023] According to this solution, by limiting this range, the second limiting part is ensured to have sufficient length and strength to effectively limit the steam valve, while avoiding material waste and increased manufacturing costs caused by excessive length.

[0024] Optionally, a plurality of the limiting portions are spaced apart along the circumferential direction of the communicating hole.

[0025] According to this scheme, by setting multiple limiting parts, the steam valve and the limiting parts are balanced in terms of force.

[0026] Optionally, the upper surface of the limiting portion includes:

[0027] A limiting surface, the shape of which is adapted to the lower surface of the steam valve;

[0028] The guide surface smoothly transitions to the limiting surface, and the guide surface is inclined to the limiting surface to guide the steam valve to abut against the limiting surface.

[0029] According to this design, the shape of the limiting surface is adapted to the lower surface of the steam valve. When the steam valve abuts against the limiting surface, the limiting surface contacts the lower surface of the steam valve to provide stable support. The inclined guide surface helps guide the steam valve into the correct position, providing a smooth positioning process. The smooth transition between the guide surface and the limiting surface ensures that the steam valve can easily and without jamming transition from the guide surface to the limiting surface, and finally make tight contact with the limiting surface.

[0030] Optionally, the outer periphery of the steam valve is thickened along the axial direction to form a reinforcing portion.

[0031] According to this solution, by adding a reinforcing section, the outer peripheral strength of the steam valve is enhanced, its resistance to deformation is improved, thereby ensuring that the steam valve maintains stable performance.

[0032] Optionally, the inner radial end of the seal is provided with a lip, the lip being used for a sealing connection with the steam valve; wherein,

[0033] At least a portion of the lip is offset from the notch, and at least a portion of the lip is located radially inside the notch; and / or

[0034] The upper surface of the steam valve is adapted to the shape of the seal.

[0035] According to this solution, the lip fits tightly against the surface of the steam valve, improving the sealing performance.

[0036] The lip is interference-fitted with the steam valve.

[0037] According to this solution, the sealing element is connected to the steam valve via an interference fit, providing a clamping force to the steam valve. The sealing element cooperates with the limiting element to provide a certain clamping force to the steam valve, ensuring a sealing effect while achieving axial limiting of the steam valve.

[0038] Optionally, at least a portion of the mounting portion protrudes from the upper surface of the cover;

[0039] The seal is provided with a groove that extends circumferentially and faces downward, and the upper edge of the mounting part is inserted into the groove.

[0040] According to this solution, by forming an interlocking fit between the seal and the mounting part, the connection strength between the seal and the mounting part is improved. At the same time, the seal provides multiple sealing barriers for the mounting part, thereby improving the sealing performance.

[0041] Optionally, the cover includes:

[0042] Inner cover, the mounting portion is formed on the inner cover.

[0043] An outer cover is connected to the upper part of the inner cover, and the outer cover is provided with a sealing rib that abuts against the upper part of the sealing element.

[0044] According to this solution, the sealing rib can limit the axial upward movement of the seal, thereby keeping the seal in its predetermined position.

[0045] Optionally, at least a portion of the sealing rib's projection along the axial direction of the connecting hole coincides with the projection of the mounting portion along the height direction.

[0046] According to this solution, the seal is clamped between the sealing rib and the mounting part, ensuring that the seal is always kept in the correct position and preventing the seal from shifting during operation. Attached Figure Description

[0093] This utility model provides a cooking appliance. The cooking appliance of this utility model can be used as a rice cooker, electric pressure cooker, electric slow cooker, electric hot pot, and soy milk maker.

[0094] The following will combine Figures 1 to 13 A detailed description of the cooking utensil according to this utility model is provided.

[0095] like Figure 1As shown, the cooking utensil 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 200 and the pot body 100. Optionally, when the lid 200 covers the pot body 100, the lid 200 is sealed to the inner pot.

[0096] It should be noted that, for ease of description, the term "lower surface" in the following text refers to the surface facing downwards when the cooking appliance is in the closed state; correspondingly, "upper surface" refers to the surface facing upwards when the cooking appliance is in the closed state.

[0097] The pot body 100 is typically a rounded rectangular parallelepiped shape and has a cylindrical inner pot storage compartment. The pot body 100 includes the inner pot, which can be freely inserted into or removed from the inner pot storage compartment 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.

[0098] Reference Figures 1 to 3 The cover 200 includes an outer cover and an inner cover. For example, the outer cover includes a faceplate 220 and a faceplate trim 210, and the inner cover includes a liner 230 and a removable cover 240. The faceplate 220 is located on the outermost side of the cover 200 to form the outer shell of the cover 200. The faceplate trim 210 is disposed on the upper surface of the faceplate 220. The removable cover 240 is oriented towards the cooking space, that is, when the cover 200 is in the closed position, the removable cover 240 is located directly above the cooking space. The liner 230 is disposed below the faceplate 220 and is connected to the faceplate 220. For example, the liner 230 can be connected to the faceplate 220 by fasteners or clips. The faceplate trim 210, the faceplate 220, and the liner 230 constitute the upper cover assembly. The upper cover assembly is mainly used to centrally install various functional components of the cover 200 that sense and control the working status of the cooking appliance, such as sensors, steam valves 300, control panels, button holders, etc. Optionally, the cover 200 is provided with a steam passage. The steam passage is formed, for example, by a portion of the liner 230 and a portion of the removable cover 240.

[0099] Refer to 1 to Figure 6The cover 230 is provided with a mounting portion 231. The mounting portion 231 forms a connecting hole 2311. The connecting hole 2311 is used to connect the cooking space with the outside, and it forms part of the steam passage. The cover 220 forms an external connecting hole 2311, which connects the steam passage with the outside. The removable cover 240 forms an internal connecting hole 241, which connects the steam passage with the cooking space. Optionally, a steam valve 300 is installed to the connecting hole 2311. The steam passage is designed to effectively guide and release steam during cooking. By installing the steam valve 300 at the connecting hole 2311, the steam flow direction can be adjusted without affecting the overall function of the steam passage. Optionally, the steam valve 300 is a micro-pressure valve. Optionally, the steam valve 300 is provided with a steam valve decorative piece 310, which is installed to the external connecting hole 2311.

[0100] Reference Figures 3 to 7 The inner peripheral wall of the connecting hole 2311 is provided with a limiting portion 400. At least part of the steam valve 300 is limited above the limiting portion 400. Optionally, the limiting portion 400 can be constructed as a groove 501 or a protrusion to ensure that the steam valve 300 will not move freely or fall off within the connecting hole 2311.

[0101] Reference Figures 1 to 3 , Figures 8 to 9 as well as Figures 12 to 13 The cooking appliance of this invention also includes a sealing element 500. The sealing element 500 is located above the steam valve 300.

[0102] In this invention, the upper limit of the steam valve 300 in the axial direction is located between the seal 500 and the limiting part 400, which constrains it during installation, ensuring that the steam valve 300 is stably installed in the working position. This reduces the sealing failure problem caused by the dimensional error of the silicone seal 500, thereby improving the overall sealing effect. This solution reduces the dependence on the dimensional accuracy of the seal 500 through structural optimization, thus allowing for the use of more universal manufacturing processes, reducing production costs, and improving product consistency.

[0103] The sealing element 500 is sealed to the mounting portion 231, with its bottom abutting against the steam valve 300. As described above, the steam valve 300 is installed into the connecting hole 2311, meaning the mounting portion 231 surrounds the outer periphery of the steam valve 300. The outer radial end of the sealing element 500 extends to the mounting portion 231, and the inner radial end extends to the upper surface of the steam valve 300, meaning the sealing element 500 covers the connection between the mounting portion 231 and the steam valve 300. By connecting to both the mounting portion 231 and the steam valve 300, the sealing element 500 effectively seals the connection between them, ensuring that steam in the steam passage flows out through the steam valve 300 and does not leak from the gap between the mounting portion 231 and the steam valve 300, thereby achieving steam regulation within the steam passage.

[0104] In this design, the seal 500 is connected to the mounting part 231 and the steam valve 300 via two parts (radial outer end and radial inner end), respectively, enhancing the stability of the system. Even if one sealing surface fails, the other sealing surface can still provide protection, preventing steam leakage to a certain extent and improving the overall system safety.

[0105] In this design, the upper surface of the steam valve 300 is sealed to the sealing element 500 to achieve a seal. The lower surface of the steam valve 300 abuts against the limiting part 400 to achieve a limiting position.

[0106] The following example uses the limiting part 400 as a protrusion, combined with the attached... Figures 6 to 7 The structure of the limiting part 400 is described in detail.

[0107] Reference Figure 6 The limiting part 400 protrudes from the inner peripheral wall of the connecting hole 2311.

[0108] Reference Figure 7 The limiting part 400 includes a first limiting part 410 extending circumferentially along the connecting hole 2311, and the steam valve 300 abuts against the upper surface of the first limiting part 410. The first limiting part 410 is constructed as a raised strip structure or an annular structure along the inner wall. The circumferentially extending first limiting part 410 ensures that the steam valve 300 is accurately guided and fixed in the correct position during installation. The steam valve 300 abutting against the upper surface of the first limiting part 410 allows the steam valve 300 to be accurately fixed in a predetermined position during installation, preventing downward displacement in the axial direction.

[0109] The limiting part 400 also includes a second limiting part 420 extending axially along the connecting hole 2311. The steam valve 300 has a locked position and an unlocked position. When the steam valve 300 is in the locked position, the second limiting part 420 abuts against the steam valve 300. The second limiting part 420 can serve as a reference during the installation process of the steam valve 300, ensuring that the steam valve 300 is installed correctly and improving product consistency. When the steam valve 300 is in the locked position, it can be firmly fixed within a certain range, preventing accidental unlocking due to misoperation, thus improving product safety and reliability.

[0110] During installation, the steam valve 300 can rotate around its central axis along the first limiting part 410, giving it a certain degree of rotational freedom. As the steam valve 300 rotates, it comes into contact with the second limiting part 420 in the circumferential direction. When it rotates to a certain angle, the second limiting part 420 stops the steam valve 300, preventing further rotation. At this point, the steam valve 300 is in place. The second limiting part 420 helps to restrict the steam valve 300's free rotation in the circumferential direction to a certain extent, ensuring that the steam valve 300 always remains in the predetermined working position.

[0111] Optionally, multiple limiting portions 400 are spaced apart along the circumferential direction of the connecting hole 2311. Specifically, multiple first limiting portions 410 are spaced apart along the circumferential direction. Multiple second limiting portions 420 are spaced apart along the circumferential direction. Optionally, the first limiting portions 410 and the second limiting portions 420 can correspond one-to-one, or multiple first limiting portions 410 can correspond to one second limiting portion 420. By setting multiple limiting portions 400, the force between the steam valve 300 and the limiting portions 400 is balanced.

[0112] Optionally, the first limiting part 410 is connected to the second limiting part 420. The first limiting part 410 and the second limiting part 420 form an L-shaped structure. The first limiting part 410 and the second limiting part 420 are connected at an angle, so that the steam valve 300 can be effectively restricted in both directions, providing more comprehensive positioning and stabilization. The L-shaped structure makes the installation of the steam valve 300 simpler and more precise, improving production efficiency.

[0113] In some embodiments of this invention, the upper surface of the first limiting portion 410 includes a limiting surface 411 and a guiding surface 412. The limiting surface 411 is adapted to the shape of the lower surface of the steam valve 300. When the steam valve 300 abuts against the limiting surface 411, the limiting surface 411 contacts the lower surface of the steam valve 300 to provide stable support for the steam valve 300. The guiding surface 412 is inclined to the limiting surface 411 to guide the steam valve 300 to abut against the limiting surface 411. The inclined guiding surface 412 helps guide the steam valve 300 into the correct position, providing a smooth positioning process. The smooth transition between the guiding surface 412 and the limiting surface 411 ensures that the steam valve 300 can easily and without jamming transition from the guiding surface 412 to the limiting surface 411 and finally make tight contact with the limiting surface 411.

[0114] Optionally, the limiting surface 411 is perpendicular to the central axis of the connecting hole 2311. That is, the limiting surface 411 is parallel to the horizontal plane. The guide surface 412 is inclined to the horizontal plane.

[0115] For example, the guide surface 412 has a first end and a second end opposite to each other in the circumferential direction, the first end being connected to the limiting surface 411. Optionally, the second end is lower or higher than the first end.

[0116] Reference Figures 8 to 11 In some embodiments of this utility model, the outer periphery of the steam valve 300 is recessed inward along its radial direction to form a notch 301, through which the limiting part 400 passes. The radial direction of the steam valve 300 refers to its direction from the edge to the center. The number of notches 301 corresponds to the number of limiting parts 400.

[0117] Optionally, the steam valve 300 can be installed into the communicating hole 2311 from the upper end, with the notch 301 for the second limiting part 420 to pass through. During installation, the steam valve 300 can directly abut against the upper surface of the first limiting part 410 from above the limiting part 400, at which point the second limiting part 420 passes through the notch 301. The steam valve 300 rotates along the upper surface of the first limiting part 410 until the peripheral wall of the notch 301 abuts against the second limiting part 420, thus completing the installation of the steam valve 300 within the communicating hole 2311.

[0118] Optionally, the steam valve 300 can be installed into the communication hole 2311 from the lower end of the communication hole 2311, and the notch 301 allows the first limiting portion 410 to pass through. When installing the steam valve 300, the steam valve 300 can pass through the first limiting portion 410 from below the limiting portion 400 and move above the first limiting portion 410. The steam valve 300 can abut against the upper surface of the first limiting portion 410. At this time, the second limiting portion 420 penetrates through the notch 301. The steam valve 300 rotates along the upper surface of the first limiting portion 410 until the peripheral wall of the notch 301 abuts against the second limiting portion 420, and the installation of the steam valve 300 in the communication hole 2311 is completed.

[0119] According to the above, the setting of the notch 301 simplifies the installation process of the steam valve 300, and the steam valve 300 can form an effective connection with the limiting portion 400 through the notch 301.

[0120] In some embodiments of the present utility model, the length of the notch 301 in the circumferential direction is greater than the length of the first limiting portion 410 in the circumferential direction. The notch 301 allows the first limiting portion 410 to pass through, so that the steam valve 300 can be installed into the communication hole 2311 from the lower end of the communication hole 2311.

[0121] Back to Figure 7 , in some embodiments of the present utility model, the range of the length L of the first limiting portion 410 in the circumferential direction is: 1 / 8D < L < 1 / 6D, where D is the circumference of the inner peripheral wall of the communication hole 2311. The length L of the first limiting portion 410 can be but is not limited to 1 / 7.5D, 1 / 7D, 1 / 6.5D, etc., and is preferably 1 / 7D. By limiting this range, it is ensured that the first limiting portion 410 has sufficient length to ensure its strength to bear the steam valve 300, and at the same time, it avoids material waste and increased manufacturing cost caused by excessive length.

[0122] In some embodiments of the present utility model, the range of the height H of the second limiting portion 420 is: H > 2 mm. The height H of the second limiting portion 420 can be but is not limited to 3 mm, 4 mm, 5 mm, etc., and is preferably 4 mm. By limiting this range, it is ensured that the second limiting portion 420 has sufficient length to ensure its strength to effectively limit the steam valve 300, and at the same time, it avoids material waste and increased manufacturing cost caused by excessive length.

[0123] Refer to Figures 10 to 11In some embodiments of this utility model, the outer periphery of the steam valve 300 is thickened along the axial direction to form a reinforcing portion 320. Optionally, the reinforcing portion 320 is constructed as a protrusion, which protrudes from the upper surface of the steam valve 300. As mentioned above, the outer periphery of the steam valve 300 is provided with a notch 301. By providing the reinforcing portion 320, the strength of the outer periphery of the steam valve 300 is enhanced, its resistance to deformation is improved, thereby ensuring that the steam valve 300 maintains stable performance.

[0124] The following is in conjunction with the appendix Figures 12 to 13 The structure of seal 500 is described in detail.

[0125] The seal 500 is constructed as a rotating body. The seal 500 can form an effective seal at the connection between the steam valve 300 and the mounting portion 231. Optionally, the seal 500 can be made of, but is not limited to, rubber or silicone.

[0126] In some embodiments of this utility model, the inner radial end of the sealing member 500 is provided with a lip 510, which is used for sealing connection with the steam valve 300. Optionally, the upper surface of the steam valve 300 is adapted to the shape of the sealing member 500; specifically, the upper surface of the steam valve 300 is adapted to the shape of the lip 510.

[0127] The elasticity and shape of the lip 510 ensure a tight fit with the surface of the steam valve 300, thereby improving sealing performance.

[0128] Optionally, the lip 510 is interference-fitted with the steam valve 300. Specifically, the lip 510 is interference-fitted with the upper surface of the steam valve 300. The interference fit between the sealing element 500 and the steam valve 300 provides a clamping force to the steam valve 300. The sealing element 500 cooperates with the limiting element to provide a certain clamping force to the steam valve 300, ensuring a sealing effect while axially limiting the steam valve 300.

[0129] In some embodiments of this invention, at least a portion of the lip 510 is offset from the notch 301, and at least a portion of the lip 510 is located radially inside the notch 301. That is, the lip 510 is closer to the central axis of its connecting hole 2311 than the notch 301, and the offset of the lip 510 from the notch 301 ensures that there is a complete sealing surface between the seal 500 and the steam valve 300 to prevent overflow.

[0130] In some embodiments of this utility model, the sealing member 500 is provided with a circumferentially extending groove 501 with its opening facing downwards, and the upper edge of the mounting portion 231 is inserted into the groove 501. In this solution, at least a portion of the mounting portion 231 protrudes from the upper surface of the cover 200, specifically, at least a portion of the mounting portion 231 protrudes from the upper surface of the liner 230. By forming an interlocking fit between the sealing member 500 and the mounting portion 231, the connection strength between the sealing member 500 and the mounting portion 231 is improved, and at the same time, the sealing member 500 provides multiple sealing barriers for the mounting portion 231, thereby improving the sealing performance.

[0131] In this application, the outer cover is provided with a sealing rib 212. Specifically, the face cover decorative member 210 is provided with a sealing rib 212. The sealing rib 212 protrudes from the lower surface of the face cover decorative member 210. The sealing rib 212 abuts against the upper part of the sealing member 500. The sealing rib 212 can limit the sealing member 500 axially upward, so that the sealing member 500 is held in its predetermined position.

[0132] Reference Figure 2 and Figure 14 In some embodiments of this utility model, at least a portion of the axial projection of the sealing rib 212 coincides with the axial projection of the mounting portion 231. The sealing member 500 is clamped between the sealing rib 212 and the mounting portion 231, ensuring that the sealing member 500 is always kept in the correct position and preventing the sealing member 500 from shifting during operation.
