Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking utensil technology, and in particular to a lid assembly and a cooking utensil. Background Technology
[0002] In the design of cooking appliances, to facilitate users to intuitively obtain information about the appliance's working status, such as cooking temperature, remaining time, and working mode, a transparent window is usually set on the top of the appliance's lid. Users can directly observe the information presented by the display module through the transparent window and keep track of the cooking process.
[0003] In existing technologies, the outer cover typically employs a spliced structure, comprising a separately machined side cover and a decorative panel detachably mounted on top of the side cover. The decorative panel is usually made of transparent materials such as glass or acrylic, and is bonded to the side cover with adhesive to form a sealed structure. However, under the conditions of high temperature, high-frequency cleaning, and steam corrosion in cooking scenarios, the sealing performance of the outer cover is prone to rapid failure, affecting the product's lifespan. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a lid assembly for a cooking utensil, which has the advantages of high sealing performance and stable and reliable use.
[0005] The specific technical solution of this utility model is as follows: it includes an outer cover, a liner, and a viewing window. The outer cover covers the liner to form a receiving cavity. A display substrate is provided in the receiving cavity. The outer cover includes a top cover and a side cover integrally formed with the top cover. An opening is provided on the top cover at a position corresponding to the display substrate. The viewing window includes a window covering the opening and a first connecting part located around the window. The viewing window is detachably connected to the outer cover through the first connecting part.
[0006] In the aforementioned cover assembly, the outer cover is a one-piece structure without any seams. The display substrate is placed within the cavity formed by the outer cover and the inner cover. The viewing window covers the opening of the outer cover, creating a sealed structure that effectively prevents moisture from seeping into the cavity and thus avoids affecting the performance of the display substrate. Meanwhile, the viewing window and the outer cover are separate units connected by a mechanical structure. Compared to traditional adhesive bonding, this connection structure completely avoids connection failures caused by adhesive deterioration during long-term use, ensuring a stable and reliable connection between the viewing window and the outer cover. These designs together guarantee the sealing performance and operational stability of the cover assembly, significantly reducing the probability of product failure and effectively extending the overall service life.
[0007] Optionally, the periphery of the window is provided with a first abutting part, the first abutting part is recessed from the window toward the cover, the first connecting part is provided on the side of the first abutting part away from the window, and the first abutting part abuts against the side of the outer cover around the opening toward the receiving cavity.
[0008] In the above technical solution, when the viewing window is placed towards the opening, the first abutting part will first contact and abut against the side of the outer cover around the opening that faces the receiving cavity, providing positioning for the installation of the viewing window, facilitating the alignment of the window with the opening and the alignment of the first connecting part with the connecting position of the outer cover, thereby improving assembly efficiency.
[0009] Optionally, the first abutment portion is provided with a first elastic seal for tightly adhering to the outer cover.
[0010] In the above technical solution, the first elastic seal tightly fits the outer cover through elastic deformation, which can fill the gaps and prevent water and steam from seeping into the cavity; at the same time, it can adapt to the thermal expansion and contraction of the outer cover, maintain the sealing surface fit during temperature changes, and improve the waterproof and leak-proof performance of the cover assembly.
[0011] Optionally, the number of the first elastic seal is one or more, and the first abutment portion has a recessed mounting groove on the side near the opening, the first elastic seal is disposed in the mounting groove, and / or the first elastic seal is disposed on the side of the first abutment portion away from the opening.
[0012] In the above technical solution, the number of first elastic seals can be one or more. The first elastic seals can be provided only in the mounting groove or only on the side of the first contact portion away from the opening, so as to reduce the seepage of water and steam into the receiving cavity. When the first elastic seals are provided in both positions, the first elastic seals provided in the mounting groove serve as the first line of defense, blocking the high-temperature steam in the cooking cavity from seeping in from the gap between the opening and the viewing window. At the same time, the recessed mounting groove can accommodate steam condensate, preventing water from flowing and spreading along the contact portion. The first elastic seals on the side away from the opening serve as the second line of defense, intercepting leaked water vapor that breaks through the first line of defense in extreme scenarios. The two lines of defense work together to prevent water and steam from seeping into the receiving cavity.
[0013] Optionally, the receiving cavity is provided with a substrate support, the display substrate is disposed on the substrate support, and the substrate support is provided with a second abutting portion extending toward the outer cover, the second abutting portion abutting at least part of the first abutting portion against the outer cover.
[0014] In the above technical solution, the second abutting part extends toward the outer cover and presses against the first abutting part, pressing the viewing window against the outer cover and cooperating with the first connecting part to improve the connection stability between the viewing window and the outer cover.
[0015] Optionally, the first connecting portion is recessed from the first abutting portion toward the cover to a position close to the display substrate, and the sidewall of the first connecting portion near the window and the sidewall of the second abutting portion near the window form an enclosing structure to define the transparent range of the viewing window.
[0016] In the above technical solution, the first connecting part and the second abutting part construct a continuous shielding boundary around the perspective path of the viewing window, preventing the outer structure from being observed by the user through the transparent window, ensuring that the viewing window only clearly presents the effective information of the display substrate, avoiding interference from non-display structures with the visual effect, and improving display clarity and product aesthetics.
[0017] Optionally, the cross-sectional dimensions of the window gradually increase from top to bottom, while the opening sidewalls gradually decrease from top to bottom, with the opening sidewalls fitting into or forming an angle with the window sidewalls.
[0018] In the above technical solution, the window and opening can form a wedge-shaped guiding fit during assembly, which improves assembly efficiency.
[0019] Optionally, the receiving cavity is provided with a substrate support, which includes a carrying platform, a second connecting part detachably connected to the outer cover, and a third abutting part extending from the periphery of the carrying platform to the outer cover. The third abutting part is located around the carrying platform and abuts against the outer cover, so that a placement space for placing the display substrate is formed between the carrying platform and the outer cover. The second connecting part is located around the third abutting part.
[0020] In the above technical solution, other functional components are provided inside the cavity, and the substrate support defines the placement space of the display substrate, is separated from other structures inside the cavity, and ensures the working stability of the display substrate.
[0021] Optionally, the third abutment portion is provided with a second elastic seal for tightly adhering to the outer cover.
[0022] In the above technical solution, the second elastic seal tightly fits the outer cover through elastic deformation, which can fill the gaps and prevent water and steam from seeping into the installation space and affecting the display substrate; at the same time, it can adapt to the thermal expansion and contraction of the outer cover, maintain the sealing surface fit during temperature changes, and improve the waterproof and leak-proof performance of the cover assembly.
[0023] Another specific technical solution of this utility model is: a cooking utensil, including a pot body and a pot lid covering the pot body, wherein the pot lid includes the aforementioned lid assembly.
[0024] Compared with the prior art, the present invention has at least the following advantages: (1) Stable and reliable connection of the viewing window: The viewing window is detachably connected to the outer cover through the first connecting part, and the viewing window is pressed against the outer cover through the first abutting part, which abandons the traditional glue bonding method and ensures that the connection between the viewing window and the outer cover remains stable and reliable during long-term use of the cooking appliance. (2) High sealing performance: The outer cover is an integral structure without splicing gaps. The display substrate is placed in the cavity formed by the outer cover and the liner. The viewing window covers the opening of the outer cover through its own window, so that the cover assembly forms a sealed structure. At the same time, the first elastic seal between the viewing window and the outer cover and the second elastic seal between the substrate support and the outer cover improve the sealing performance of the key connection points in the cavity. The sidewall of the opening and the sidewall of the window form an inclined mating surface, which can prevent external water from entering the cavity. The multiple structures work together to improve the overall sealing performance of the cover assembly. Attached Figure Description

[0027] The present invention will be further described below with reference to embodiments. Unless otherwise specified, all devices, connection structures, and methods involved in this invention are known in the art.
[0028] Example 1 Reference Figures 1 to 4 As shown, this utility model provides a lid assembly for a cooking appliance, including an outer lid 1, a liner, and a viewing window 3. The outer lid 1 covers the liner to form a receiving cavity 16, and a display substrate 4 is disposed within the receiving cavity 16. The outer lid includes a top and a side integrally formed with the top. An opening 18 is formed on the top corresponding to the display substrate 4. The viewing window 3 is disposed at the opening 18 and includes a window 6 covering the opening 18 and a first connecting portion 8 located around the window 6. The first connecting portion 8 is disposed on the side of the outer lid 1 facing the receiving cavity 16, and the viewing window 3 is detachably connected to the outer lid 1 through the first connecting portion 8. The viewing window 3 is made of a transparent material such as glass or acrylic sheet, while the outer shell is made of a non-transparent material.
[0029] In the aforementioned cover assembly, the outer cover 1 is an integral structure without any seams. The display substrate 4 is placed within the cavity 16 formed by the outer cover 1 and the liner. The viewing window 3 covers the opening 18 of the outer cover 1 through its own window 6, thus forming a sealed structure for the cover assembly. This effectively prevents moisture from seeping into the cavity and avoids affecting the performance of the display substrate 4. At the same time, the viewing window 3 and the outer cover 1 are separately designed and connected in a detachable manner through a mechanical structure. Compared with traditional glue bonding, this connection structure can completely avoid connection failure caused by glue deterioration during long-term use, ensuring that the connection between the viewing window 3 and the outer cover 1 is always stable and reliable. The above design together ensures the sealing performance and operational stability of the cover assembly, significantly reduces the probability of product failure, and effectively extends the overall service life.
[0030] In this embodiment, the outer cover 1 is an integral structure, which avoids the gaps caused by splicing multiple parts in the split design. This reduces the risk of moisture and dust entering the receiving cavity 16 through the splicing gaps, and also makes the surface of the cover present a complete and flat visual effect, significantly improving the overall aesthetics of the product.
[0031] In this embodiment, as Figure 2 As shown, a substrate support 5 is provided within the receiving cavity 16. The substrate support 5 includes a carrying platform 13, a second connecting portion 15 detachably connected to the outer cover 1, and a third abutting portion 10 extending from the periphery of the carrying platform 13 towards the outer cover 1. The third abutting portion 10 is located around the carrying platform 13 and abuts against the outer cover 1, thereby forming a placement space 17 for placing the display substrate 4 between the carrying platform 13 and the outer cover 1. It is connected to the outer cover 1 by a fastener, which in this embodiment is a bolt. In another embodiment, as shown... Figure 3 As shown, the second connecting part 15 is provided with a locking block protruding towards the outer cover 1, and the outer cover 1 is provided with a corresponding locking groove protruding towards the second connecting part 15. The base plate bracket 5 is connected and fixed to the outer cover 1 by the locking of the second connecting part 15 and the outer cover 1.
[0032] The cavity 16 houses other functional components, and the substrate support 5 defines the placement space 17 for the display substrate 4, separating it from other structures within the cavity to ensure the operational stability of the display substrate 4. It should be noted that the fixing method of the substrate support 5 is not unique; it can also be detachably connected to the cover via the second connecting part 15, achieving fixation within the cover assembly. The specific fixing method can be flexibly selected based on the internal structure of the cavity 16. It is understood that the third abutting part 10 in this embodiment can be selectively provided. In other embodiments, the second connecting part 15 can also be located around the platform 13 and detachably connected to the outer cover 1, forming the placement space 17 for the display substrate 4 between the platform 13 and the outer cover 1.
[0033] In this embodiment, the cross-sectional area of the window 6 corresponds to the cross-sectional area of the display screen of the display substrate 4, and the cross-sectional area of the window 6 is smaller than the cross-sectional area of the placement space 17 defined by the substrate support 5.
[0034] In this preferred embodiment, the third abutment portion 10 surrounds the periphery of the loading platform 13 to completely separate the placement space 17 from the receiving cavity 16, thereby preventing other structures and moisture from interfering with the display substrate 4.
[0035] To improve the sealing performance of the cover assembly, such as Figure 2 As shown, the outer cover 1 has a connecting groove extending towards the third abutment portion 10. The third abutment portion 10 extends into the connecting groove, and the third abutment portion 10 has a second elastic sealing member 12 for tightly fitting the outer cover 1. The second elastic sealing member 12 enters the connecting groove and abuts against the bottom of the groove. The second elastic member is an elastic ring. The second elastic sealing member 12 fits tightly against the outer cover 1 through elastic deformation, which can fill gaps and prevent water and steam from seeping into the placement space 17 and affecting the display substrate 4. At the same time, it can adapt to the thermal expansion and contraction of the outer cover 1, maintaining the sealing surface fit during temperature changes, thus improving the waterproof and leak-proof performance of the cover assembly.
[0036] In this embodiment, as Figure 2 As shown, the viewing window 3 includes a window 6, a first connecting portion 8, and a first abutting portion 7. The first connecting portion 8 is connected to the outer cover 1 via a fastener. The first abutting portion 7 is located around the periphery of the window 6 and is recessed from the window 6 toward the cover. The first connecting portion 8 is located on the side of the first abutting portion 7 away from the window 6, and the first abutting portion 7 abuts against the side of the outer cover 1 around the opening 18 near the receiving cavity 16. When the viewing window 3 is placed toward the opening 18, the first abutting portion 7 will first contact and abut against the side of the outer cover 1 around the opening 18 toward the receiving cavity 16, providing positioning for the installation of the viewing window 3, facilitating the alignment of the window 6 with the opening 18 and the connection position of the first connecting portion 8 with the outer cover 1, thus improving assembly efficiency.
[0037] In this embodiment, as Figure 2 As shown, the first connecting part 8 is connected to the outer cover 1 by a fastener, which is a bolt. In another embodiment, as... Figure 3 As shown, the first connecting part 8 is provided with a latching block protruding towards the outer cover 1, and the outer cover 1 is provided with a corresponding latching groove protruding towards the first connecting part 8. The viewing window 3 is connected and fixed to the outer cover 1 through the latching of the first connecting part 8 and the outer cover 1.
[0038] To improve the connection stability of View3, such as Figure 2As shown, the substrate support 5 also includes a second abutting portion 9 extending from the periphery of the loading platform 13 to the outer cover 1. The second connecting portion 15 is disposed inside the third abutting portion 10. The second abutting portion 9 abuts at least part of the first abutting portion 7 against the outer cover 1 and cooperates with the first connecting portion 8 to improve the connection stability between the viewing window 3 and the outer cover 1.
[0039] Furthermore, such as Figure 2 As shown, the first connecting portion 8 is recessed from the first abutting portion 7 toward the cover to a position close to the display substrate 4. The sidewall of the first connecting portion 8 near the window 6 and the sidewall of the second abutting portion 9 near the window 6 form an enclosing structure to limit the transparent range of the viewing window 3. The first connecting portion 8 and the second abutting portion 9 construct a continuous blocking boundary around the perspective path of the viewing window 3, preventing the surrounding structure from being observed by the user through the transparent window 6, ensuring that the viewing window 3 only clearly presents the effective information of the display substrate 4, avoiding interference from non-display structures with the visual effect, and improving display clarity and product aesthetics.
[0040] To avoid air and water leaks around Exit 18, such as Figure 2 As shown, the first abutment portion 7 is provided with a first elastic seal for tightly adhering to the outer cover 1. The number of first elastic seals can be one or more, and the first elastic element can be a sealing ring, a sealing gasket, or a combination of both. The first elastic seal 11, through elastic deformation, tightly adheres to the outer cover 1, filling gaps and preventing water and steam from seeping into the receiving cavity 16; simultaneously, it can adaptively deform with the thermal expansion and contraction of the outer cover 1, maintaining the sealing surface adherence during temperature changes, thus improving the waterproof and leak-proof performance of the cover assembly.
[0041] To further improve the sealing performance of the cover assembly, such as Figure 2 As shown, two first elastic seals 11 are provided. A recessed mounting groove 14 is provided on the side of the first abutment portion 7 near the opening 18. One first elastic seal 11 is located in the mounting groove 14, and the other first elastic seal 11 is located on the side of the first abutment portion 7 away from the opening 18. In this embodiment, the first elastic seal 11 in the mounting groove 14 is an elastic sealing ring, and the other first elastic seal 11 is an elastic gasket. The first elastic seal in the mounting groove serves as the first line of defense, preventing high-temperature steam from seeping into the cooking cavity from the gap between the opening and the viewing window. Simultaneously, the recessed mounting groove can accommodate steam condensation, preventing moisture from flowing and spreading along the abutment portion. The first elastic seal on the side away from the opening serves as the second line of defense, intercepting leaked water vapor that may breach the first line of defense in extreme scenarios. The two lines of defense work together to prevent water and steam from seeping into the receiving cavity. Understandably, in other embodiments, the number of first elastic seals 11 is one, and it can be set in one of the two positions mentioned above. The first elastic seal can be set only in the mounting groove or only on the side of the first abutment portion away from the opening, so as to form at least an effective sealing barrier to reduce the infiltration of water and steam into the receiving cavity.
[0042] The installation process of the cover assembly of this application is as follows: first, the viewing window 3 is connected to the outer cover 2 by a fastener, the display substrate 4 is connected to the substrate support 5 by a fastener, and then the substrate support 5 is connected to the outer cover 1.
[0043] To improve the ease of installation of the cover components, such as Figure 2 As shown, the cross-sectional dimensions of window 6 gradually increase from top to bottom, while the sidewalls of opening 18 gradually decrease from top to bottom. The sidewalls of opening 18 fit or abut against the sidewalls of window 6. When window 6 and opening 18 are assembled, a wedge-shaped guide fit is formed, improving assembly efficiency.
[0044] Example 2 This utility model provides a cooking appliance, including a pot body and a pot lid covering the pot body. The pot body is provided with a cooking cavity for containing food and a heating component for heating the cooking cavity. The pot lid includes the lid assembly of the above embodiment 1.
[0045] The cooking appliance also includes a main control board, which is electrically connected to the display board. The main control board can be selectively installed in the pot body or pot lid according to the actual structure of the cooking appliance.
[0046] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
