Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and specifically relates to a pot cover assembly and a cooking utensil. Background Art

[0002] Cooking utensils are indispensable daily necessities in people's daily lives, which include a pot body and a pot cover that can cover the pot body, wherein the pot cover includes a lining cover, an inner cover arranged on the lining cover, and a sealing ring, the sealing ring has an edge located between the lining cover and the inner cover, so that the lining cover and the inner cover can squeeze the edge to fix the sealing ring, and a retaining edge cooperating with a lining cover stopper is arranged on the inner side of the edge to increase the stability of the sealing ring.

[0003] In existing pot lids, the inner lid is usually detachable and washable, which makes it easy for users to detach and wash the inner lid with little effort, and will not cause damage to the inner lid and the sealing ring. However, for pot lids whose inner lid and lining cover are not detachable, when users wipe the sealing ring, they apply a large force to the sealing ring, which may cause the sealing ring to deform greatly and pull the edge, which may easily cause the edge to separate from between the lining cover and the inner lid, thereby affecting the airtightness and cooking effect of the cooking utensil. Moreover, once the edge separates from between the lining cover and the inner lid, the sealing ring cannot be reinstalled, so that the airtightness and cooking effect of the cooking utensil cannot be restored, and it is more urgent to solve the above problem. Utility Model Content

[0004] The present application provides a pot cover assembly and a cooking utensil to increase the stability of a sealing ring and ensure the air tightness of the cooking utensil and the cooking effect.

[0005] The technical solution adopted in this application is:

[0006] A pot cover assembly comprises a lining cover, an inner cover and a sealing member, wherein the lining cover comprises a fixed outer ring matched with a surface cover and a fixed inner ring fastened to the inner cover, the sealing member comprises a sealing portion, a blocking portion and a connecting portion connecting the blocking portion and the sealing portion, the fixed inner ring and the inner cover squeeze and fix the connecting portion, and the thickness of the blocking portion is greater than the thickness of the connecting portion.

[0007] The pot cover assembly described in this application also includes the following additional technical features:

[0008] The thickness A of the blocking portion and the thickness B of the connecting portion satisfy: A≥2.5B.

[0009] The blocking portion has a first end connected to the connecting portion and a second end opposite to the first end, and the thickness of the first end is equal to the thickness of the second end;

[0010] Alternatively, the thickness of the second end is smaller than the thickness of the first end.

[0011] An included angle α is formed between the blocking portion and the connecting portion, wherein 45°≤α≤135°.

[0012] The lining cover has a convex rib and a blocking rib located outside the convex rib, and a receiving groove for receiving the blocking portion is formed between the blocking rib and the convex rib.

[0013] An extension portion is arranged at the inner side of the sealing portion, the extension portion is arranged to be inclined upward in a direction close to the center of the sealing portion, and the inner end of the extension portion abuts against the inner cover.

[0014] A flange is extended from the outer periphery of the inner cover, and the flange has an extrusion plane that contacts the connecting portion.

[0015] The inner cover is provided with a fastener, and the fastener thread extends into the lining cover.

[0016] The lining cover and / or the inner cover are provided with a pressurizing protrusion, and the pressurizing protrusion is pressed tightly against the connecting portion.

[0017] The present application also discloses a cooking utensil, comprising a pot body and the above-mentioned pot cover assembly, wherein the pot body is provided with an inner pot, and when the pot cover assembly is closed over the pot body, the sealing portion abuts against the edge of the inner pot, so that the inner cover and the inner pot together form a sealed cooking cavity.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0019] 1. The pot cover assembly in the present application includes a lining cover, an inner cover and a sealing member, the lining cover includes a fixed outer ring matched with the surface cover and a fixed inner ring fastened to the inner cover, the sealing member includes a sealing portion, a blocking portion and a connecting portion connecting the blocking portion and the sealing portion, the fixed inner ring and the inner cover squeeze the fixed connecting portion, the thickness of the blocking portion is greater than the thickness of the connecting portion, and then when the user wipes the seal, the sealing portion is stressed and generates a pulling force on the connecting portion, so that the connecting portion has a tendency to separate from between the fixed inner ring and the inner cover under the action of the pulling force, because the thickness of the blocking portion is greater than the thickness of the connecting portion, and the gap between the inner cover and the fixed inner ring is consistent, the blocking portion cannot pass through the gap between the inner cover and the fixed inner ring, so that the blocking portion can block the connecting portion to keep the connecting portion in a relatively static state, thereby reducing the risk of the connecting portion separating from between the fixed inner ring and the inner cover, increasing the connection stability between the seal and the fixed inner ring and the inner cover, ensuring the airtightness and cooking effect of the cooking utensil equipped with the pot cover assembly, and improving the user experience.

[0020] In addition, since the thickness of the blocking part is greater than the thickness of the connecting part, the elastic force of the blocking part is increased. Therefore, during the installation of the seal, if the installation position of the connecting part is skewed, the blocking part will contact the fixed inner ring and deform, so that the blocking part can restore the deformation under the action of its own elastic force and drive the connecting part to move, and then the connecting part is adjusted to the extrusion position under the action of the blocking part, so as to further increase the connection stability between the seal and the fixed inner ring and the inner cover, and improve the assembly efficiency of the pot cover assembly by the staff.

[0021] 2. As a preferred embodiment of the present application, the thickness A of the blocking portion and the thickness B of the connecting portion satisfy: A ≥ 2.5B, so as to further increase the thickness difference between the blocking portion and the connecting portion, and then further increase the blocking effect of the blocking portion on the connecting portion, further reduce the risk of the connecting portion being separated from the fixed inner ring and the inner cover, and further ensure the airtightness and cooking effect of the cooking utensil. In addition, the elastic force of the blocking portion is greatly improved, so as to further increase the adjustment effect of the blocking portion on the connecting portion, and further improve the assembly efficiency of the pot cover assembly.

At the same time, the elastic force of the blocking part can be guaranteed, and the adjustment ability of the blocking part to itself can be increased, so that when the seal is installed, the blocking part can be quickly reset under the action of its own elastic force, improve the assembly efficiency of the seal, reduce the risk of the blocking part overlapping with the connecting part under the action of external force, so as to further increase the connection stability of the seal with the fixed inner ring and the inner cover, and further improve the user experience.

[0023] 4. As a preferred embodiment of the present application, an extension is provided on the inner side of the sealing portion, and the extension is inclined upward in a direction close to the center of the sealing portion, and the inner end of the extension contacts the inner cover, so that the extension can apply an upward elastic force to the inner cover, and then the extension is pressed against the inner cover under the action of this force, thereby increasing the connection sealing between the extension and the inner cover, increasing the sealing between the seal and the inner cover, further increasing the airtightness and cooking effect of the cooking utensil installed with the pot cover assembly, and further improving the user experience. At the same time, the seal can be applied to pot cover assemblies of various models to increase the flexibility of the seal and reduce the production cost of the pot cover assembly. In addition, the extension can compensate for the gap caused by production errors or assembly errors to ensure the sealing between the seal and the inner cover, and then ensure the airtightness and cooking effect of the cooking utensil installed with the pot cover assembly.

[0024] 5. As a preferred embodiment of the present application, the outer periphery of the inner cover is extended with a flange, and the flange has an extrusion plane that contacts the connection part to increase the contact area between the inner cover and the connection part, thereby increasing the friction between the inner cover and the connection part, thereby increasing the extrusion and fixing effect of the inner cover on the connection part, thereby increasing the fixing stability of the seal, and further ensuring the airtightness and cooking effect of the cooking utensil installed with the pot cover assembly. In addition, the contact plane increases the contact area between the inner cover and the connection part, and can also reduce the pressure between the inner cover and the connection part, reduce the risk of possible damage to the connection part, and then increase the service life of the connection part, thereby increasing the service life of the seal, and further improving the user experience.

[0045] Reference Figures 1 to 6 A pot cover assembly includes a lining cover 1, an inner cover 2 and a sealing member 3. The lining cover 1 includes a fixed outer ring 14 matched with the surface cover and a fixed inner ring 15 fastened to the inner cover 2. The sealing member 3 includes a sealing portion 31, a blocking portion 32 and a connecting portion 33 connected to the blocking portion 32 and the sealing portion 31. The fixed inner ring 15 and the inner cover 2 squeeze and fix the connecting portion 33. The thickness of the blocking portion 32 is greater than the thickness of the connecting portion 33.

[0046] When the user wipes the seal 3, the seal 31 is stressed and generates a pulling force on the connection part 33, so that the connection part 33 has a tendency to separate from the fixed inner ring 15 and the inner cover 2 under the action of the pulling force. Since the fixed inner ring 15 is fastened to the inner cover 2, the gap between the inner cover 2 and the fixed inner ring 15 is kept consistent. At the same time, the thickness of the blocking part 32 is greater than the thickness of the connection part 33, so that the blocking part 32 can block the connection part 33 to keep the connection part 33 in a relatively static state, thereby reducing the risk of the connection part 33 separating from the fixed inner ring 15 and the inner cover 2, increasing the connection stability between the seal 3 and the fixed inner ring 15 and the inner cover 2, ensuring the airtightness and cooking effect of the cooking appliance equipped with the pot cover assembly, and improving the user experience.

[0047] In addition, since the thickness of the blocking portion 32 is greater than the thickness of the connecting portion 33, the elastic force of the blocking portion 32 is increased, so that during the installation of the seal 3, if the installation position of the connecting portion 33 is skewed, the blocking portion 32 will contact the fixed inner ring 15 and deform, so that the blocking portion 32 recovers the deformation under the action of its own elastic force and drives the connecting portion 33 to move, and then the connecting portion 33 is adjusted to the extrusion position under the action of the blocking portion 32, so as to further increase the connection stability between the seal 3 and the fixed inner ring 15 and the inner cover 2, and improve the assembly efficiency of the pot cover assembly by the staff.

[0048] The present application does not specifically limit the structure of the sealing portion 31. Preferably, refer to Figure 1 and Figure 4 The sealing portion 31 is an annular structure and has a V-shaped cross section to increase the sealing effect on the pot body 5. In other embodiments, the sealing portion 31 can also be a sheet structure or other structure with a certain thickness, as long as it can be able to contact the edge of the inner pot 51 to form a sealed cooking cavity between the inner pot 51 and the inner cover 2.

[0049] The present application does not specifically limit the structure of the connecting portion 33. Preferably, refer to Figure 1 and Figure 4 The connecting portion 33 is an annular structure to increase the contact area between the connecting portion 33 and the inner cover 2 and the fixed inner ring 15, thereby improving the connection stability between the sealing member 3 and the inner cover 2 and the fixed inner ring 15, thereby reducing the risk of the sealing member 3 being separated from the fixed inner ring 15 and the inner cover 2, further ensuring the airtightness and cooking effect of the cooking utensil equipped with the pot cover assembly, and further improving the user experience. In other embodiments, the connecting portion 33 can also be a strip structure arranged at intervals along the circumference of the sealing portion 31 to reduce the production cost of the sealing member 3.

[0050] The present application does not specifically limit the structure of the blocking portion 32. Preferably, refer to Figure 1 and Figure 4 The blocking portion 32 is an annular structure to increase the blocking effect of the blocking portion 32 on the connecting portion 33, thereby increasing the connection stability between the seal 3 and the inner cover 2 and the fixed inner ring 15, reducing the risk of the seal 3 being separated from the fixed inner ring 15 and the inner cover 2, further ensuring the airtightness and cooking effect of the cooking utensil equipped with the pot cover assembly, and further improving the user experience. At the same time, the blocking portion 32 increases the structural strength of the connecting portion 33 to reduce the risk of damage to the connecting portion 33 and increase the service life of the seal 3. In other embodiments, the blocking portion 32 can also be a strip structure arranged at intervals along the circumference of the connecting portion 33 to reduce the production cost of the seal 3.

[0051] In a preferred embodiment, referring to Figure 5 and Figure 6 , the thickness A of the blocking portion 32 and the thickness B of the connecting portion 33 satisfy: A ≥ 2.5B, so as to further increase the thickness difference between the blocking portion 32 and the connecting portion 33, and then further increase the blocking effect of the blocking portion 32 on the connecting portion 33, further reduce the risk of the connecting portion 33 being separated from the fixed inner ring 15 and the inner cover 2, and further ensure the airtightness and cooking effect of the cooking utensil installed with the pot cover assembly. In addition, the elastic force of the blocking portion 32 is greatly improved, so as to further increase the adjustment effect of the blocking portion 32 on the connecting portion 33, and further improve the assembly efficiency of the pot cover assembly.

[0052] The present application does not specifically limit the structure of the blocking portion 32, and it may adopt any one of the following embodiments:

[0053] Embodiment 1. In this embodiment, referring to Figure 4 and Figure 5 The blocking portion 32 has a first end connected to the connecting portion 33 and a second end opposite to the first end, and the thickness of the first end is equal to the thickness of the second end, so as to ensure the blocking effect of the blocking portion 32 on the connecting portion 33, further reduce the risk of the connecting portion 33 being separated from the fixed inner ring 15 and the inner cover 2, further ensure the airtightness and cooking effect of the cooking utensil installed with the pot cover assembly, and improve the user experience. At the same time, the elastic force of the blocking portion 32 can be guaranteed, and the adjustment ability of the blocking portion 32 itself can be increased, so that when the sealing member 3 is installed, the blocking portion 32 can be quickly reset under the action of its own elastic force, improve the assembly efficiency of the sealing member 3, reduce the risk of the blocking portion 32 overlapping with the connecting portion 33 under the action of external force, further increase the connection stability of the sealing member 3 with the fixed inner ring 15 and the inner cover 2, and further improve the user experience.

[0054] Better, refer to Figure 4 and Figure 5 The blocking portion 32 has a first side surface and a second side surface opposite to the first side surface, and the first side surface and the second side surface are arranged in parallel so that the thickness of the first end and the second end are equal. That is to say, the thickness of the blocking portion 32 remains consistent in the direction away from the connecting portion 33 to ensure the blocking effect of the blocking portion 32 on the connecting portion 33, and further ensure the air tightness and cooking effect of the cooking utensil installed with the pot cover assembly.

[0055] Implementation method 2. In this implementation method, refer to Figure 6 The blocking portion 32 has a first end connected to the connecting portion 33 and a second end opposite to the first end, and the thickness of the second end is less than the thickness of the first end, so as to reduce the space required for the blocking portion 32 while ensuring the blocking effect on the connecting portion 33, thereby increasing the compactness of the pot cover assembly and making it easier to miniaturize the pot cover assembly.

[0056] Preferably, the sealing portion 31 has a straight wall section connected to the connecting portion 33, and the blocking portion 32 has a blocking surface facing the straight wall section and a supporting surface away from the straight wall section, the blocking surface is arranged parallel to the straight wall section, and the supporting surface is arranged inclined from top to bottom toward the direction close to the straight wall section, that is, the thickness of the blocking portion 32 gradually decreases along the direction from the first end to the second end, so as to ensure the blocking effect of the blocking portion 32 on the connecting portion 33 and ensure the connection stability of the sealing member 3.

[0057] In this embodiment, refer to Figure 6 The thickness A of the blocking portion 32 refers to the thickness of the first end, so as to ensure the blocking effect of the blocking portion 32 on the connecting portion 33, thereby increasing the stability of the sealing member 3 and ensuring the air tightness and cooking effect of the cooking utensil equipped with the pot cover assembly.

[0058] In a preferred embodiment, there is an angle α between the blocking portion 32 and the connecting portion 33, wherein 45°≤α≤135°, so that the blocking portion 32 occupies less lateral space, leaving enough space for installing other components, and at the same time, it can be convenient to assemble other components, so as to improve the production efficiency of the pot cover assembly. In addition, the blocking effect of the blocking portion 32 on the connecting portion 33 can be increased to further increase the stability of the sealing member 3, thereby ensuring the airtightness and cooking effect of the cooking utensil installed with the pot cover assembly.

[0059] Preferably, α=90°, that is, the blocking portion 32 and the connecting portion 33 together form an L-shape, so as to further reduce the lateral space occupied by the blocking portion 32, improve the structural compactness of the pot cover assembly, and facilitate the miniaturization design of the pot cover assembly. At the same time, the blocking effect of the blocking portion 32 on the connecting portion 33 is further improved, thereby further increasing the stability of the sealing member 3.

[0060] In a preferred embodiment, referring to Figure 4 , Figure 5 and Figure 6 The lining cover 1 has a convex rib 11 and a blocking rib 12 located outside the convex rib 11 , and a receiving groove 111 for receiving the blocking portion 32 is formed between the blocking rib 12 and the convex rib 11 .

[0061] Specifically, the convex rib 11 and the blocking rib 12 are both arranged on the fixed inner ring 15. After the pot cover assembly is assembled, the convex rib 11 and the inner cover 2 jointly squeeze the connecting portion 33 to fix the sealing member 3, and the blocking portion 32 is located in the accommodating groove 111 to accommodate the blocking portion 32 so that the blocking portion 32 can move freely, thereby increasing the blocking effect of the blocking portion 32 on the connecting portion 33 and avoiding the situation in which the connecting portion 33 cannot be squeezed due to the thickness of the blocking portion 32 being greater than the thickness of the connecting portion 33, thereby increasing the stability of the sealing member 3.

[0062] The present application does not specifically limit the structure of the rib 11. Preferably, refer to Figure 4 , Figure 5 and Figure 6 The convex ribs 11 are all arranged to extend along the circumference of the fixed inner ring 15, that is, the convex ribs 11 are annular structures to increase the contact area of ​​the convex ribs 11 on the connecting portion 33, thereby increasing the squeezing effect on the connecting portion 33, and further increasing the stability of the sealing member 3, while also ensuring the structural strength of the convex ribs 11, so as to further ensure the squeezing effect of the convex ribs 11 on the connecting portion 33. In other embodiments, the convex ribs 11 can also be arranged at intervals along the circumference of the fixed inner ring 15 to reduce the production cost of the pot cover assembly.

[0063] Better, refer to Figure 4 , Figure 5 and Figure 6 The convex rib 11 has a pressure plane facing the connection part 33, and the pressure plane contacts the connection part 33, so that the convex rib 11 applies pressure to the connection part 33 through the pressure plane, so as to increase the contact area between the convex rib 11 and the connection part 33, thereby increasing the friction between the convex rib 11 and the connection part 33, and further increasing the stability of the sealing member 3. In addition, the pressure plane can also reduce the pressure between the connection part 33 and the convex rib 11, so as to avoid the situation where the convex rib 11 applies a large extrusion force to the connection part 33, thereby reducing the difficulty of assembling the pot cover assembly, and further improving the assembly efficiency of the pot cover assembly.

[0064] The present application does not specifically limit the structure of the barrier rib 12. Preferably, refer to Figure 4 , Figure 5 and Figure 6 The blocking rib 12 is arranged to extend along the circumference of the fixed inner ring 15, that is, the blocking rib 12 is an annular structure, and the distance between the blocking rib 12 and the blocking portion 32 is less than the depth of the blocking portion 32 extending into the receiving groove 111, so that the blocking rib 12 can block and support the deformed blocking portion 32, so as to further increase the force required when the connecting portion 33 is separated from the fixed inner ring 15 and the inner cover 2, thereby further increasing the blocking effect of the blocking portion 32 on the connecting portion 33, thereby increasing the stability of the sealing member 3, and at the same time, it can also increase the structural strength of the blocking rib 12 and the structural strength of the lining cover 1. In other embodiments, the blocking rib 12 can also be arranged at intervals along the circumference of the fixed inner ring 15 to reduce the production cost of the pot cover assembly.

[0065] In a preferred embodiment, referring to Figure 5 and Figure 6 An extension portion 311 is disposed on the inner side of the sealing portion 31 . The extension portion 311 is inclined upward in a direction close to the center of the sealing portion 31 , and the inner end of the extension portion 311 contacts the inner cover 2 .

[0066] It should be noted that the attached Figure 5 and Figure 6 The extension portion 311 in the figure is just a simple schematic diagram. In an actual product, the extension portion 311 will be deformed under the action of the inner cover 2 and will contact the inner cover 2, so that the extension portion 311 can seal the gap between the inner cover 2 and the sealing portion 31.

[0067] Specifically, the extension portion 311 is extended along the circumference of the sealing portion 31, and the inner end of the extension portion 311 contacts the inner cover 2, so that the extension portion 311 can apply an upward elastic force to the inner cover 2, and then the extension portion 311 is pressed against the inner cover 2 under the action of this force, thereby increasing the connection sealing of the extension portion 311 and the inner cover 2, so as to increase the sealing between the seal 3 and the inner cover 2, further increase the airtightness and cooking effect of the cooking utensil installed with the pot cover assembly, and further improve the user's experience. At the same time, the seal 3 can be applied to pot cover assemblies of various models to increase the flexibility of the seal 3 and reduce the production cost of the pot cover assembly. In addition, the extension portion 311 can compensate for the gap caused by production error or assembly error to ensure the sealing between the seal 3 and the inner cover 2, and then ensure the airtightness and cooking effect of the cooking utensil installed with the pot cover assembly.

[0068] In a preferred embodiment, referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 A flange 21 is extended from the outer periphery of the inner cover 2 , and the flange 21 has an extrusion plane that contacts the connecting portion 33 .

[0069] After the seal 3 is installed between the fixed inner ring 15 and the inner cover 2, the inner cover 2 squeezes the connection part 33 through the squeezing plane to increase the contact area between the inner cover 2 and the connection part 33, and then increases the friction between the inner cover 2 and the connection part 33, thereby increasing the squeezing and fixing effect of the inner cover 2 on the connection part 33, so as to increase the fixing stability of the seal 3, and further ensure the air tightness and cooking effect of the cooking utensil installed with the pot cover assembly. In addition, the contact plane increases the contact area between the inner cover 2 and the connection part 33, and can also reduce the pressure between the inner cover 2 and the connection part 33, reduce the risk of possible damage to the connection part 33, and then increase the service life of the connection part 33, thereby increasing the service life of the seal 3, and further improving the user experience.

[0070] The present application does not specifically limit the fastening connection method between the inner cover 2 and the fixed inner ring 15. Preferably, refer to Figure 1 , Figure 2 and Figure 3The inner cover 2 is provided with a fastener 4, and the fastener 4 is threadedly extended into the lining cover 1 to increase the connection stability between the inner cover 2 and the fixed inner ring 15, thereby increasing the stability of the sealing ring and reducing the risk of the connection part 33 being separated from the inner cover 2 and the fixed inner ring 15, while improving the assembly efficiency of the pot cover assembly to reduce the production cost of the pot cover assembly.

[0071] Preferably, a plurality of fasteners 4 are arranged at circumferential intervals along the inner cover 2 to increase the connection points between the inner cover 2 and the fixed inner ring 15, thereby increasing the connection stability between the inner cover 2 and the fixed inner ring 15, while ensuring that the axial gap between the inner cover 2 and the fixed inner ring 15 remains consistent, so as to increase the stability of the seal 3, thereby ensuring the air tightness and cooking effect of the cooking utensil equipped with the pot cover assembly.

[0072] The present application does not specifically limit the structure of the fastener 4. Preferably, the fastener 4 is a self-tapping screw to increase the connection stability between the inner cover 2 and the fixed inner ring 15 and facilitate the assembly of the pot cover assembly. In other embodiments, the fastener 4 can also be a bolt.
