Description

Technical Field

[0001] This utility model relates to a cooking utensil, and more particularly to a sealing ring and a pot using the same. Background Technology

[0002] A high-quality sealing ring effectively prevents steam and heat from escaping, allowing a high-temperature, high-pressure environment to form inside the pot more quickly. For example, pressure cookers rely on the sealing ring to increase internal pressure, raising the boiling point of water above 100°C and significantly shortening cooking time. A well-sealed lid reduces internal heat convection disturbances, preventing localized heat loss and ensuring more even heating of food, thereby improving heating efficiency.

[0003] Experiments show that when using a poorly sealed lid, heat loss through steam can reach 20%-30%. A good seal can retain this energy inside the pot, reducing the need for continuous heating. For example, when stewing meat, a well-sealed pot can reduce cooking time from 2 hours to 1.5 hours, directly reducing gas or electricity consumption.

[0004] The sealing ring of the lid has a significant impact on cooking efficiency and energy consumption. Maintaining a good seal can shorten heating time, save energy, and improve the quality of dishes, making it an essential detail in the kitchen.

[0005] When heated, the sealing ring can generate a large pressure inside the pot. However, when the pressure is too high, it will damage the sealing ring. Therefore, it is a technical problem that needs to be solved in order to balance maintaining a high pressure inside the pot and preventing the sealing ring from being damaged. Utility Model Content

[0006] This invention designs a sealing ring and a cookware using it, which solves the technical problem of balancing maintaining a high pressure inside the pot with ensuring the sealing performance of the sealing ring is not compromised.

[0007] To solve the aforementioned technical problems, the present invention adopts the following solution:

[0008] A sealing ring having a groove that can be fitted onto the edge of a lid, characterized in that: the sealing ring has a single-layer convex ring or a double-layer convex ring, the single-layer convex ring forming a gap with the sealing ring or the double-layer convex ring forming a gap by itself, the steam inside the pot can pass through the gap to fit the single-layer convex ring or the double-layer convex ring onto the L-shaped sealing surface on the pot body.

[0009] Preferably, the single-layer convex ring is inclined towards the center of the cover, and one end of it is connected to any position between the outer ring and the inner ring of the sealing ring, including the outer ring and the inner ring.

[0010] Preferably, the cross-section of the single-layer convex ring is an inclined wavy shape or an inclined strip shape, the wavy shape being formed by multiple "V" or "U" shapes extending outwards; and / or the length of the single-layer convex ring is greater than or less than or equal to the width of the sealing ring.

[0011] Preferably, the cross-section of the double-layer convex ring is a "V" shape, a "U" shape, or a wave shape formed by the extension of multiple "V" or "U" shapes, or a wave shape is formed on the surface of the "V" or "U" shape, or another wave shape is formed on the surface of the wave shape formed by the extension of multiple "V" or "U" shapes; one end of the "V" or "U" shape or wave shape is connected to any position between the outer ring and the inner ring of the sealing ring, including the outer ring and the inner ring; the length of the double-layer convex ring is greater than, less than or equal to the width of the sealing ring.

[0012] A cookware includes a lid and a pot body, characterized in that: the sealing ring is connected to the lid, and the lid is fixed by a lid pressing mechanism.

[0013] Preferably, it also includes two pot ears, each pot ear being connected to the pot body via an L-shaped sealing surface.

[0014] Preferably, the L-shaped sealing surface includes a vertical sealing surface and a horizontal sealing surface, which are arranged vertically or at an angle. A single-layer or double-layer convex ring adheres to the vertical sealing surface and / or the horizontal sealing surface under the action of steam.

[0015] Preferably, the lid is provided with a vent valve, which releases air when the pressure inside the pot reaches a certain value due to heating; or, the vent valve can not only release air when the pressure inside the pot reaches a certain value due to heating, but also seal the pot together with the sealing ring when the pot stops heating.

[0016] Preferably, the lid pressing mechanism includes a movable pressing block and a support member. The support member has an installation groove, and the pot ear is fixed in the installation groove. Two second guide members are provided above the support member, and a movable pressing block is provided between the two second guide members. The first guide blocks on both sides of the movable pressing block cooperate with one of the second guide members. When the movable pressing block moves forward to the top of the lid, it prevents the lid from popping up. When the movable pressing block moves backward and no longer prevents the lid from popping up, the lid can be opened.

[0017] Preferably, the lid pressing mechanism includes a mounting ear, a rotating pressing block, and an operating handle. The mounting ear is fixedly connected to the edge of the pot body, the rotating pressing block is connected to the mounting ear through a rotating shaft, and the operating handle is located on the rotating pressing block.

[0020] (2) This utility model enables the pot to form a high temperature and high pressure environment more quickly. Then, the lid is pressed by the lid pressing mechanism, which takes into account both maintaining the high pressure inside the pot and ensuring that the sealing ring is not damaged. It can maintain a high pressure environment inside the pot for a long time and ensure that the pot edge does not leak air or water, thus improving the steaming and stewing quality.

[0021] (3) The vent valve in this utility model can vent when the pot is heated, and can seal the pot together with the sealing ring through the negative pressure inside the pot when the pot stops heating, so as to achieve long-term heat preservation inside the pot. Attached Figure Description

Detailed Implementation

[0045] The following is combined with Figures 1 to 21 The present invention will be further described below:

[0046] Example 1:

[0047] like Figures 1-5As shown, a sealing ring has a groove 23 that can be fitted onto the edge of the lid 1. The sealing ring 2 has a single-layer raised ring 21, forming a gap 22 between the single-layer raised ring 21 and the sealing ring 2. Steam inside the pot can pass through the gap 22 to press the single-layer raised ring 21 against the L-shaped sealing surface 41 on the pot body 4. The lid 1 is equipped with a vent valve 3, which vents air when the pressure inside the pot reaches a certain value due to heating; alternatively, the vent valve 3 can not only vent air when the pressure inside the pot reaches a certain value due to heating, but also seal the pot body 4 together with the sealing ring when heating stops. The vent valve 3 can have only an venting function, or it can have both venting and sealing functions.

[0048] The single-layer convex ring 21 is inclined towards the center of the cover, and one end of it is connected to the edge of the outer ring 26 of the sealing ring 2. The cross-section of the single-layer convex ring 21 is an inclined wavy shape or an inclined strip shape. The wavy shape is formed by multiple "V" or "U" shapes. The length of the single-layer convex ring 21 is greater than, less than or equal to, the width of the sealing ring 2.

[0049] The L-shaped sealing surface 41 includes a vertical sealing surface and a horizontal sealing surface, which are arranged vertically or at an angle. The single-layer convex ring 21 is attached to the vertical sealing surface and / or the horizontal sealing surface under the action of steam.

[0050] like Figure 3 and Figure 4 As shown, a cookware includes a lid 1 and a pot body 4. A sealing ring is connected to the lid 1, and the lid 1 is fixed by a lid pressing mechanism 5. It also includes two pot handles 42, each of which is connected to the pot body 4 via an L-shaped sealing surface 41.

[0051] Example 2:

[0052] like Figures 5 to 8 As shown, a sealing ring has a groove 23 that can be fitted onto the edge of the cover 1. The sealing ring 2 is provided with a double-layer convex ring 24. Through the gap 25 formed by the double-layer convex ring 24, the steam in the pot can adhere the double-layer convex ring 24 to the L-shaped sealing surface 41 on the pot body 4.

[0053] The cross-section of the double-layer convex ring 24 is a "V" shape, a "U" shape, or a wave shape formed by the extension of multiple "V" or "U" shapes, or a wave shape formed on the surface of a "V" or "U" shape, or another wave shape formed on the surface of a wave shape formed by the extension of multiple "V" or "U" shapes; one end of the "V" or "U" or wave shape is connected to the edge of the inner ring 27 of the sealing ring 2. The length of the double-layer convex ring 24 is greater than, less than, or equal to the width of the sealing ring 2. The so-called wave shape is a combination of multiple "V" or multiple "U" shapes.

[0054] The difference between the wavy cross-section of the single-layer convex ring 21 and the wavy cross-section of the double-layer convex ring 24 is that the single-layer convex ring forms a wavy shape on the overall strip, while the wavy cross-section of the double-layer convex ring 24 means that the double-layer convex ring 24 is composed of at least two straight strips, and multiple straight strips form multiple "V" or multiple "U" wavy shapes.

[0055] If a wave shape is formed on the surface of the double-layer convex ring 24 at the same time, then it will be a double wave sealing structure.

[0056] The L-shaped sealing surface 41 includes a vertical sealing surface and a horizontal sealing surface, which are arranged vertically or at an angle. The double-layer convex ring 24 is attached to the vertical sealing surface and / or the horizontal sealing surface under the action of steam.

[0057] In Example 2, the double-layer convex ring 24 has a more complex structure than the single-layer convex ring 21 in Example 1, and it is easier to fit onto the L-shaped sealing surface 41 to form a good sealing structure.

[0058] like Figure 7 and Figure 8 As shown, a cookware includes a lid 1 and a pot body 4. A sealing ring is connected to the lid 1, and the lid 1 is fixed by a lid pressing mechanism 5. It also includes two pot handles 42, each of which is connected to the pot body 4 via an L-shaped sealing surface 41.

[0059] Example 3:

[0060] like Figures 9 to 11 As shown, the first structure of the cover pressing mechanism 5 includes a movable pressing block 51 and a support member 53. The support member 53 has an installation groove 54, and the pot ear 42 is fixed in the installation groove 54. Two second guide members 55 are provided above the support member 53, and the movable pressing block 51 is provided between the two second guide members 55. The first guide blocks 52 on both sides of the movable pressing block 51 cooperate with one of the second guide members 55 respectively. When the movable pressing block 51 moves forward to the top of the cover 1, it prevents the cover 1 from popping up. When the movable pressing block 51 moves backward and no longer prevents the cover 1 from being blocked, the cover 1 can be opened.

[0061] The second structure of the lid pressing mechanism (refer to Chinese Patent Application No.: 2024231743300, title: A cooking pot) includes a mounting ear, a rotating pressing block, and an operating handle. The mounting ear is fixedly connected to the edge of the pot body, the rotating pressing block is connected to the mounting ear through a rotating shaft, and the operating handle is located on the rotating pressing block. Rotating the operating handle can cause the rotating pressing block to rotate, and the rotating pressing block can press the lid down by rotating.

[0062] The third type of lid pressing mechanism can also be achieved by moving the pressing block to rotate around an axis. After the pressing block rotates to the top of the lid, it is fixed to the pot ear or the lid pressing mechanism itself by a snap fastener.

[0063] In summary, the sealing ring of this utility model forms a good fit with the L-shaped sealing surface 41 through the action of steam. When a high pressure is generated inside the pot, the lid pressing mechanism ensures that the lid will not be pushed open by the pressure inside the pot, thus maintaining the pressure inside the pot.

[0064] This utility model can be used for woks, stew pots, or hot pots, etc.

[0065] like Figure 12 As shown, the lower inclined surface of the single-layer convex ring 21 is provided with multiple protrusions 211. The protrusions 211 can be "V" or "U" so that the cross section of the single-layer convex ring 21 has an inclined wave shape.

[0066] like Figure 13 As shown, the single-layer convex ring 21 has multiple protrusions 211 on its inclined surface. The protrusions 211 can be "V" or "U" so that the cross-section of the single-layer convex ring 21 has an inclined wave shape.

[0067] like Figure 14 As shown, the single-layer convex ring 21 has multiple protrusions 211 on both the upper and lower inclined surfaces. The protrusions 211 can be "V" or "U" so that the cross-section of the single-layer convex ring 21 has an inclined wave shape.

[0068] like Figure 15 As shown, the outer side of the double-layer convex ring 24 is provided with multiple protrusions 241, which can be "V" or "U" so that the cross section of the double-layer convex ring 24 has an inclined wave shape.

[0069] like Figure 16 As shown, the inner side of the double-layer convex ring 24 is provided with a plurality of protrusions 241 in the "V" or "U" shape. The protrusions 241 can be "V" or "U" so that the cross section of the double-layer convex ring 24 has an inclined wave shape.

[0070] like Figure 17 As shown, the inner and outer sides of the "V" or "U" shape of the double-layer convex ring 24 are provided with multiple protrusions 241. The protrusions 241 can be "V" or "U" so that the cross-section of the double-layer convex ring 24 has an inclined wave shape.

[0071] like Figure 18 As shown, the double-layer convex ring 24 is a wave shape formed by the combination and extension of multiple "V" or "U" shapes.

[0072] like Figure 19 As shown, the inner sides of the double-layer convex ring 24 are provided with multiple protrusions 241, which are also "V" or "U" shaped, so that the cross-section of the double-layer convex ring 24 has a double wave shape.

[0073] like Figure 20As shown, the double-layer convex ring 24 has multiple protrusions 241 on the outer side of multiple "V" or "U" shapes. The protrusions 241 are also "V" or "U" shaped, so that the cross section of the double-layer convex ring 24 has a double wave shape.

[0074] like Figure 21 As shown, the double-layer convex ring 24 has multiple protrusions 241 on the inner and outer sides of multiple "V" or "U" shapes. The protrusions 241 are also "V" or "U" shaped, so that the cross-section of the double-layer convex ring 24 has a double wave shape.

[0075] Figures 12-17 as well as Figures 19-21 The protrusions 211 or 241 in the middle form a wave shape, but should also include a wave shape formed by the inward indentation of a single-layer protruding ring 21 or a double-layer protruding ring 24.

[0076] The aforementioned "V" or "U" or wavy shapes can enhance the sealing effect of the sealing ring.
