Description

[Technical Field]

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to cooking utensils. [Background Technology]

[0002] Existing cooking appliances include a pot body and a lid. The pot body includes an inner pot, and the lid includes an outer lid assembly, a metal inner lid, and a temperature measuring component. The temperature measuring component includes a temperature measuring rod on the outer lid assembly. The metal inner lid has a sealing ring. When the lid is closed on the pot body, the inner pot flips up and engages with the sealing ring to achieve a seal. After long-term use, the sealing ring on the metal inner lid is easily contaminated and difficult to clean, leading to problems such as discoloration, mold, and displacement of the sealing ring. Continued use will affect the quality of cooking rice and is also detrimental to the health of the consumer, thus reducing the user experience.

[0003] To address the aforementioned technical problems, Chinese patent CN207532306U discloses a technical solution for achieving a sealing fit between the edge of the metal inner lid and the flange of the inner pot without a sealing ring. Specifically, the metal inner lid is floatingly mounted on the outer lid assembly. Pressure is applied to the metal inner lid via an elastic element, pressing its outer edge against the flange of the inner pot, thus achieving a sealing fit. However, due to the low structural strength of the metal inner lid, its edge is prone to deformation, leading to seal failure between the inner lid edge and the inner pot flange. Furthermore, for small-sized rice cookers, the overall size of the inner lid is also small, resulting in a small radial dimension of its edge. This limits the contact between the metal inner lid edge and the inner pot flange, making a seal impossible. Therefore, this sealing method is not suitable for small-sized rice cookers and has poor versatility. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cooking utensil that can effectively improve the reliability of the seal between the inner lid and the inner pot.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cooking utensil includes a pot body and a lid that fits onto the pot body. The pot body includes an outer pot and an inner pot housed within the outer pot. The lid includes an outer lid assembly and an inner lid. The inner pot includes a constricted neck and a flared portion located above the constricted neck. The inner surface of the flared portion forms a sealing surface. The inner lid has a sealing recessed platform that is recessed towards the inner pot. The sealing recessed platform fits tightly against the sealing surface to achieve a seal.

[0007] In the aforementioned cooking appliance, the outer periphery of the sealing platform forms a tight seal with the sealing surface.

[0008] In the above-mentioned cooking appliance, the sealing surface is a conical surface that gradually tapers from the opening of the inner pot towards the bottom of the inner pot, and the side wall of the sealing platform includes a conical segment that gradually tapers towards the bottom of the inner pot, and the conical segment is adapted to and tightly fitted to the conical surface.

[0009] In the aforementioned cooking appliance, the sidewall of the sealed platform further includes a vertically extending cylindrical section, the lower end of which is connected to a conical section, and the upper end of which is connected to the edge of the inner cover.

[0010] In the above-mentioned cooking appliance, the sealing surface is a stepped surface, which includes a vertically extending first sealing surface and a horizontally extending second sealing surface. The side wall of the sealing platform is in close contact with the first sealing surface, and the bottom surface of the sealing platform is in close contact with the second sealing surface.

[0011] Among the above-mentioned cooking appliances, the cooking appliance also includes a steamer, which is placed in the inner pot and located below the sealed platform, and there is a clearance between the sealed platform and the steamer.

[0012] In the above-mentioned cooking appliance, the inner lid is floatingly mounted on the outer lid assembly, and a first elastic element is provided between the inner lid and the outer lid assembly, and / or the inner pot is floatingly mounted on the outer pot, and a second elastic element is provided between the inner pot and the outer pot, wherein the first elastic element applies pressure to the inner lid and / or the second elastic element supports the inner pot upward.

[0013] In the above-mentioned cooking appliance, a plurality of first elastic elements are provided between the inner cover and the outer cover assembly, and the first elastic elements are pressed into the edge of the bottom wall of the sealing platform.

[0014] In the aforementioned cooking appliance, the outer cover assembly includes a liner covering the outside of the inner cover, and the first elastic member includes a pressing member and a first spring clamped between the pressing member and the liner, the first spring applying pressure to the pressing member to press the pressing member onto the inner cover.

[0015] In the aforementioned cooking appliance, the inner pot has a first flange extending outward at its opening, and the outer pot has a second elastic member at its top, which supports the first flange upward.

[0016] The beneficial effects of this utility model are:

[0017] 1. The inner lid of this utility model has a sealing recessed platform formed in the direction of the inner pot. The inner pot includes a constricted neck and a flared portion located above the constricted neck. The inner side of the flared portion forms a sealing surface. The sealing recessed platform, formed in the direction of the inner pot, fits snugly with the sealing surface to achieve a seal. This eliminates the need for a sealing ring on the inner lid, thereby eliminating the problems of odor and mold caused by the presence of a sealing ring, improving the user experience and protecting the user's health. In addition, since the design space of the inner side of the inner pot is larger than that of the flanged top surface, placing the sealing surface on the inner side of the flared portion allows for a larger sealing surface area. This increases the area of ​​tight contact between the sealing recessed platform and the inner pot. Furthermore, the design of the sealing recessed platform also enhances the structural strength of the mating part between the sealing recessed platform and the sealing surface, thus preventing deformation of the sealing recessed platform and a deterioration in the sealing effect between it and the sealing surface. This further improves the sealing reliability of the inner lid and the inner pot. Finally, the design of the sealing recessed platform has lower requirements for the overall size of the inner lid, making it suitable for small-sized rice cookers and more versatile.

[0018] 2. The outer periphery of the sealing platform forms a tight seal with the sealing surface. Compared to making the bottom surface of the sealing platform form a tight seal with the sealing surface, this solution only requires the sealing surface to extend from the opening of the inner pot towards the bottom of the inner pot. The sealing surface can be formed using an existing inner pot or by making slight modifications to the inner side of the inner pot, thereby reducing the modification cost of the inner pot.

[0019] 3. The sealing surface is a conical surface that gradually tapers from the opening of the inner pot towards the bottom. The sidewall of the sealing platform includes a conical section that gradually tapers towards the bottom of the inner pot. The conical section fits and fits tightly with the conical surface. This design allows the sealing platform to be smoothly inserted into the inner pot, and the fit between the conical section and the sealing surface becomes increasingly tight as the insertion depth of the sealing platform increases, thereby further improving the sealing effect between the sealing platform and the sealing surface.

[0020] 4. The sidewall of the sealing platform also includes a vertically extending cylindrical section. The lower end of the cylindrical section connects to the conical section, and the upper end of the cylindrical section connects to the edge of the inner cover. This design enhances the structural strength of the conical section and prevents deformation of the conical section from affecting its sealing performance with the sealing surface.

[0021] 5. The sealing surface is a stepped surface, comprising a vertically extending first sealing surface and a horizontally extending second sealing surface. The sidewall of the sealing recess is in close contact with the first sealing surface, and the bottom surface of the sealing recess is in close contact with the second sealing surface. This design allows for a double sealing fit between the sealing recess and the sealing surface, thereby improving the sealing reliability between the sealing recess and the sealing surface.

[0022] 6. The cooking appliance also includes a steamer, which is placed inside the inner pot and located below the sealed platform, with a clearance between the sealed platform and the steamer. This design, by setting a clearance, prevents the sealed platform from contacting the steamer, thus avoiding the steamer obstructing the insertion of the sealed platform into the inner pot, thereby ensuring a reliable and tight fit between the sealed platform and the sealing surface.

[0023] 7. By applying pressure to the inner cover with the first elastic element and / or by supporting the inner pot upwards with the second elastic element, the sealing platform and the sealing surface can be kept in close contact under the action of elastic force, thereby further increasing the sealing reliability of the sealing platform and the sealing surface.

[0024] 8. A plurality of circumferentially evenly spaced first elastic elements are provided between the inner cover and the outer cover assembly. The first elastic elements are pressed against the edge of the bottom wall of the sealing platform. With this design, since the sealing between the sealing platform and the sealing surface is achieved by relying on the outer periphery of the sealing platform, the distance between the first elastic elements and the outer periphery of the sealing platform can be shortened by pressing the first elastic elements against the edge of the bottom wall of the sealing platform. This reduces the pressure loss caused by the leverage effect when the pressure is transmitted to the outer periphery of the sealing platform, allowing the outer periphery of the sealing platform to be subjected to greater pressure, thereby improving the tightness of the fit between the sealing platform and the sealing surface.

[0025] 9. The outer cover assembly includes a liner covering the outer side of the inner cover. The first elastic element includes a pressing element and a first spring clamped between the pressing element and the liner. The first spring applies pressure to the pressing element to press the pressing element onto the inner cover. This design increases the contact area between the first elastic element and the inner cover, thereby enhancing the reliability of the pressing of the first elastic element onto the inner cover.

[0026] 10. The inner pot has a first flange extending outward at its opening, and the outer pot has a second elastic element at its top, which supports the first flange upward. This design allows the first flange to be directly supported by the upward force of the second elastic element, thereby reducing the force loss transmitted to the sealing surface due to the leverage effect, and allowing the sealing surface to receive greater support force, thus improving the tightness of the seal between the sealing platform and the sealing surface.

[0027] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

[0037] This utility model provides a cooking utensil, including a pot body and a lid that fits onto the pot body. The pot body includes an outer pot and an inner pot housed within the outer pot. The lid includes an outer lid assembly and an inner lid. The inner pot includes a constricted neck and a flared portion located above the constricted neck. The inner side of the flared portion forms a sealing surface. The sealing platform fits tightly with the sealing surface to achieve a seal.

[0038] The inner lid of this invention features a recessed sealing platform that curves inward toward the inner pot. The inner pot includes a constricted neck and a flared portion above the constricted neck. The inner surface of the flared portion forms a sealing surface. The recessed sealing platform fits snugly against the sealing surface to achieve a seal, thus eliminating the need for a sealing ring on the inner lid. This eliminates the problems of odor and mold caused by the sealing ring, improving the user experience and protecting the user's health. Furthermore, since the inner surface of the inner pot has a larger design space than the flanged top surface, placing the sealing surface on the inner surface of the flared portion allows for a larger sealing surface area. This increases the area where the sealing platform fits snugly against the inner pot. The design of the sealing platform also enhances the structural strength of the mating part between the sealing platform and the sealing surface, preventing deformation of the sealing platform and a deterioration in the sealing effect. This further improves the sealing reliability of the inner lid and the inner pot. Finally, the design of the sealing platform has lower requirements for the overall size of the inner lid, making it suitable for small-sized rice cookers and more versatile.

[0040] Example 1

[0041] like Figures 1 to 5 As shown, in this embodiment, the cooking appliance includes a pot body 100 and a lid 200 covering the pot body 100. The pot body 100 includes an outer pot 110 and an inner pot 120 housed within the outer pot 110 (e.g., ...). Figure 6As shown, the inner pot 120 includes a constricted neck 121 and a flared portion 122 located above the constricted neck 121. The inner side of the flared portion 122 forms a sealing surface 1221. The lid 200 includes an outer lid assembly 210 and a metal inner lid 220. The inner lid 220 has a sealing recess 221 recessed towards the inner pot 120. The sealing recess 221 fits against the sealing surface 1221 to achieve a seal, thereby eliminating the need for a sealing ring on the inner lid 220. This eliminates the problems of odor and mold caused by the presence of a sealing ring, improves the user experience, and protects the user's health. In addition, because the design space of the inner side of the inner pot 120 is relatively large compared to the top surface of the inner pot's flange... With a larger design space, the sealing surface 1221 is located on the inner side of the flared portion 122, allowing for a larger sealing surface 1221. This increases the area of ​​tight contact between the sealing platform 221 and the inner pot 120. In addition, the design of the sealing platform 221 also enhances the structural strength of the mating part between the sealing platform 221 and the sealing surface 1221, thereby preventing deformation of the sealing platform 221 and the sealing surface 1221 from deteriorating the sealing effect. This further improves the sealing reliability between the inner lid 220 and the inner pot 120. Finally, the design of the sealing platform 221 has lower requirements for the overall size of the inner lid 220, making it suitable for small-sized rice cookers and more versatile.

[0042] Specifically, in this embodiment, the outer periphery of the sealing platform 221 and the sealing surface 1221 form a tight seal. Compared to making the bottom surface of the sealing platform 221 and the sealing surface 1221 form a tight seal, this design only requires the sealing surface 1221 to extend from the opening of the inner pot 120 towards the bottom of the inner pot 120. The sealing surface 1221 can be formed using an existing inner pot or with slight modifications to the inner surface of the inner pot, thereby reducing the modification cost of the inner pot 120.

[0043] Preferably, in this embodiment, the sealing surface 1221 is a conical surface that gradually tapers from the opening of the inner pot towards the bottom of the inner pot. The sidewall of the sealing platform 221 includes a conical segment 2211 that gradually tapers towards the bottom of the inner pot. The conical segment 2211 fits and fits tightly with the conical surface. This design allows the sealing platform 221 to be smoothly inserted into the inner pot 120, and the fit between the conical segment 2211 and the sealing surface 1221 becomes increasingly tight as the insertion depth of the sealing platform 221 increases, thereby further improving the sealing effect between the sealing platform 221 and the sealing surface 1221. To facilitate user access to the inner pot 120, the opening of the existing inner pot 120 is usually provided with a first flange 123 extending radially outward. The top surface of the first flange 123 is connected to the top of the conical surface through an arc transition, so that the top of the conical surface surrounds the opening of the inner pot. This allows the sealing platform 221 to be smoothly inserted into the inner pot 120 when the inner lid 220 is closed on the inner pot 120.

[0044] In this embodiment, the length L of the conical segment 2211 is greater than 6 mm, thereby increasing the sealing area between the conical segment 2211 and the conical surface, thus improving the sealing reliability between the conical segment 2211 and the conical surface. Furthermore, the vertical height H of the conical segment 2211 is greater than 12 mm, thereby increasing the structural strength of the conical segment 2211, preventing deformation, and further ensuring the sealing reliability between the conical segment 2211 and the conical surface.

[0045] To further enhance the structural strength of the conical segment 2211, in this embodiment, the sidewall of the sealing platform 221 also includes a vertically extending cylindrical segment 2212. The lower end of the cylindrical segment 2212 is connected to the conical segment 2211, and the upper end of the cylindrical segment 2212 is connected to the edge of the inner cover 220. This design enhances the structural strength of the conical segment 2211 and prevents deformation of the conical segment 2211 from affecting its sealing performance with the sealing surface 1221.

[0046] To facilitate the processing of the sealing surface 1221, in this embodiment, the side wall of the inner pot 120 includes an arc-shaped segment 124, and a flared portion 122 is connected between the first flange 123 and the arc-shaped segment 124. The flared portion 122 is a tapered segment whose outer radial direction gradually increases towards the first flange 123, thereby enabling the inner side of the flared portion 122 to form the aforementioned sealing surface 1221.

[0047] It is understood that in other embodiments of this utility model, the sidewall of the inner pot is a vertically extending columnar wall, and the inner side of the columnar wall can be partially cut off to form the above-mentioned constricted neck and flared mouth.

[0048] To further improve the tightness of the fit between the sealing recess 221 and the sealing surface 1221, and thus enhance the sealing performance of the sealing recess 221 and the sealing surface 1221, in this embodiment, the inner cover 220 is floatingly mounted on the outer cover assembly 210, and a first elastic element 230 is provided between the inner cover 220 and the outer cover assembly 210. By applying pressure to the inner cover 220 through the first elastic element 230, the sealing recess 221 and the sealing surface 1221 can achieve a tight fit.

[0049] It should be noted that the existing inner cover 220 is usually installed on the outer cover assembly 210 in a detachable manner. That is, the outer cover assembly 210 has a slot (not shown in the figure) near the side where it is hinged to the pot body 100, and a buckle (not shown in the figure) on the side away from the side where it is hinged to the pot body 100. When assembling the inner cover 220 and the outer cover assembly 210, one end of the inner cover 220 is first inserted into the slot, and then the other end of the inner cover 220 is pressed towards the outer cover assembly 210 to make the other end of the inner cover 220 engage with the buckle. This detachable connection method will cause the inner cover 220 to float slightly up and down relative to the outer cover assembly 210, thus forming the inner cover 220 floatingly installed on the outer cover assembly 210.

[0050] Furthermore, in this embodiment, there are multiple first elastic elements 230, which are evenly spaced around the center of the inner cover 220. The first elastic elements 230 are pressed onto the edge of the bottom wall of the sealing platform 221, that is, the first elastic elements 230 are pressed onto the bottom wall of the sealing platform 221 and close to the conical section 2211. With this design, since the sealing with the sealing surface 1221 is achieved by relying on the conical section 2211, the distance between the first elastic element 230 and the conical section 2211 can be shortened by pressing the first elastic element 230 onto the edge of the bottom wall of the sealing platform 221. This reduces the loss of pressure when it is transmitted to the conical section 2211 due to the leverage effect, allowing the conical section 2211 to be subjected to greater pressure, thereby improving the tightness of the fit between the sealing platform 221 and the sealing surface 1221.

[0051] In this embodiment, the outer cover assembly 210 includes a liner 211 covering the outside of the inner cover 220. The first elastic member 230 includes a pressing member 231 and a first spring 232 clamped between the pressing member 231 and the liner 211. The pressing member 231 is a pressing sleeve with an open upper end and a closed lower end. The first spring 232 is disposed inside the pressing sleeve. The liner 211 includes a liner body 2111 and a guide seat 2112 fixedly installed on the liner body 2111. In this embodiment... The guide seat 2112 is independently machined, and the cover body 2111 has an upwardly recessed mounting groove 21110. The guide seat 2112 is fixed in the mounting groove 21110 by screws. The guide seat 2112 has a guide hole for inserting the pressing sleeve. The side wall of the guide hole has multiple vertically extending snap holes 21120. The top of the pressing sleeve has multiple upwardly extending elastic buckles 2311 spaced around it. The elastic buckles 2311 and the snap holes 21120 are connected. The 20-type snap-fit ​​assembly can float vertically relative to the snap-fit ​​hole 21120. The bottom wall of the guide hole is provided with a positioning protrusion. The upper end of the first spring 232 is sleeved on the positioning protrusion, and the first spring 232 is pressed between the guide seat 2112 and the pressing member 231. In this way, the first spring 232 can apply pressure to the pressing member 231 so that the pressing member 231 is pressed onto the inner cover 220. By setting the pressing member 231, the contact area between the first elastic member 230 and the inner cover 220 can be increased, thereby enhancing the pressing reliability of the first elastic member 230 on the inner cover 220. In addition, the first spring 232 can be hidden to prevent it from coming into contact with water and rusting when wiping the outer cover assembly 210 after the inner cover 220 is removed, thereby extending the service life of the first spring 232. Finally, the screw hole through which the screw passes by the screw head sealing mounting groove 21110 can also prevent the steam entering between the inner cover 220 and the liner 211 from being discharged through the screw hole.

[0052] It is understood that in other embodiments of this utility model, the guide seat can also be integrally injection molded with the cover body; or the guide seat can be omitted, and a snap-fit ​​hole can be provided on the side wall of the mounting groove so that the elastic buckle snaps into the snap-fit ​​hole and can float vertically relative to the snap-fit ​​hole.

[0053] It is understood that in other embodiments of this utility model, the first elastic element is a spring, the upper end of the spring is fixedly connected to the liner, and the lower end of the spring is connected to the inner cover.

[0054] It is understood that in other embodiments of this utility model, in order to ensure that the tapered segment is subjected to uniform pressure in the circumference, the number of the first elastic element may be one, which may be an annular silicone element, a ring-shaped rubber element, or a large-sized spring arranged around the center of the inner cover.

[0055] Finally, the cooking appliance in this embodiment also includes a steamer 300, which includes a cage body 310 and an opening rim 320 formed by bending the top of the cage body 310 outward. The outer diameter of the cage body 310 is smaller than the minimum inner diameter of the conical surface, while the outer diameter of the opening rim 320 is between the maximum inner diameter and the minimum outer diameter of the conical surface. This allows the steamer 300 to be placed in the inner pot 120. The steamer 300 is located below the sealing platform 221, and the sealing platform 221 and the steamer 300 are in contact or have a clearance greater than 0 (i.e., not in contact). Preferably, there is a clearance greater than 0 between the sealing platform 221 and the steamer 300. This design, by setting a clearance, can prevent the sealing platform 221 from contacting the steamer 300, so as to avoid the steamer 300 from obstructing the insertion of the sealing platform 221 into the inner pot 120, thereby ensuring a reliable and tight fit between the sealing platform 221 and the sealing surface 1221.

[0056] It is understood that in other embodiments of this utility model, the sealing surface is a stepped surface, which includes a vertically extending first sealing surface and a horizontally extending second sealing surface. That is, the top of the side wall of the inner pot is bent outward to form a stepped portion, the stepped portion forms a flared portion, the vertical surface of the stepped portion forms the first sealing surface, the horizontal surface of the stepped portion forms the second sealing surface, the side wall of the sealing platform is tightly fitted with the first sealing surface, the bottom surface of the sealing platform is tightly fitted with the second sealing surface, and the second sealing surface surrounds the neck of the opening. This design allows for a double sealing fit between the sealing platform and the sealing surface, thereby improving the sealing reliability between the sealing platform and the sealing surface.

[0057] It is understood that in other embodiments of this utility model, the top of the side wall of the inner pot is bent outward to form a stepped portion, and the transverse surface of the stepped portion forms a sealing surface. Under the pressure of the first elastic member, the bottom surface of the sealing platform is tightly fitted with the sealing surface to achieve a seal.

[0058] It is understood that in other embodiments of this utility model, the inner cover can also be fixedly installed on the outer cover assembly. By ensuring the processing and assembly accuracy of the pot lid and the pot body, it can also be ensured that the sealing platform and the sealing surface form a close seal after the pot lid is closed on the pot body.

[0059] It is understood that in other embodiments of this invention, the first flange may also fit tightly against the edge of the inner lid. This design further improves the sealing reliability between the inner lid and the inner pot.

[0060] Example 2

[0061] like Figure 6 As shown, compared with Embodiment 1, the difference in this embodiment is that the inner pot 120 is floatingly mounted on the outer pot 110. Specifically, the outer pot 110 has a receiving cavity, and the inner pot 120 is placed in the receiving cavity. The top of the outer pot 110 is provided with a second elastic element 400. There are multiple second elastic elements 400, which surround the outer side of the inner pot 120 and are evenly spaced circumferentially. The second elastic element 400 can be an elastic silicone block, a rubber block, or a spring. The second elastic element 400 is clamped between the top of the outer pot 110 and the first flange 123 and supports the first flange 123 upwards, thereby realizing the inner pot The inner pot 120 is floatingly mounted on the outer pot 110. By having the second elastic element 400 support the first flange 123 upward, the inner pot 120 can be supported upward, so that the sealing surface 1221 tends to move towards the inner lid 220, and the sealing platform 221 and the sealing surface 1221 can achieve a tight seal. In addition, by having the first flange 123 directly receive the upward support force of the second elastic element 400, the force loss transmitted to the sealing surface 1221 due to the lever effect can be reduced, so that the sealing surface 1221 can receive a greater support force, thereby improving the tightness of the seal between the sealing platform 221 and the sealing surface 1221.

[0062] It is understood that in other embodiments of this utility model, some of the first elastic members are disposed on the top of the outer pot to support the first flange upward, and some of the first elastic members may also be disposed on the bottom of the outer pot and contact the bottom of the inner pot to support the inner pot upward; or, all the second elastic members are disposed on the bottom of the outer pot and contact the bottom of the inner pot to support the inner pot upward.

[0063] It should be noted that in other embodiments of this utility model, in order to improve the tight fit between the sealing platform and the sealing surface to achieve a seal, the inner cover is floatingly mounted on the outer cover assembly, and a first elastic element is provided between the inner cover and the outer cover assembly. Additionally, the inner pot is floatingly mounted on the outer pot, and a second elastic element is provided between the inner pot and the outer pot. By applying pressure to the inner cover with the first elastic element and supporting the inner pot upward with the second elastic element, the sealing platform and the sealing surface can achieve a tight fit and seal.
