[0002] At present, cooking appliances such as rice cookers on the market generally use sealing rings to cooperate with the inner pot to form a seal. Since the surfaces where the sealing ring and the inner pot cooperate are usually flat, the conventional sealing ring is set in a "<" shape. The sealing effect between the sealing ring and the inner pot is ensured by forming a certain amount of compression when the sealing ring set in the "<" shape is fitted with the inner pot, thereby preventing the cooking appliance from leaking during the cooking process.

[0003] However, with the improvement of production technology and the changes in product appearance brought about by consumers' preference for products, edging structures began to appear on the upper end of the inner pot, especially arc-shaped or step-shaped edging, which resulted in the "<"-shaped sealing ring being unable to fully fit with the inner pot, resulting in a significant reduction in the sealing effect. The cooking utensils began to leak during the cooking process, giving consumers a poor experience. Utility Model Content

Therefore, they cannot be understood as limiting this application.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0031] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8The present application discloses a cooking device. The cooking device includes a pot body 1 and an upper cover 3. In some embodiments, an inner pot 2 is provided inside the pot body 1; the upper cover 3 is movably connected to the upper end of the pot body 1, and the upper cover 3 is provided with a sealing ring 4, and the sealing ring 4 is provided with a sealing arc surface 41 and a guide arc surface 42, and the sealing arc surface 41 and the guide arc surface 42 are arranged in sequence from top to bottom; when the upper cover 3 is covered on the upper end of the pot body 1, the guide arc surface 42 plays a guiding role, driving the sealing arc surface 41 to form a seal with the inner pot 2. Preferably, the guiding arc surface 42 contacts and cooperates with the inner pot 2, driving the sealing arc surface 41 to fit tightly with the upper end of the inner pot 2 to form a seal when the upper cover 3 is covered on the upper end of the pot body 1, so that the inner pot 2 with the edging portion 21 fits tightly with the sealing ring 4 to form a good sealing effect, prevent air leakage, ensure that the inner pot 2 retains enough moisture during cooking, enhance the moisture content and taste of the food, and improve the user experience.

[0032] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 When the upper cover 3 is closed, the sealing ring 4 is in close contact with the upper cover 3 and the sealing ring 4 is in close contact with the lower cover 3.

[0033] See Figure 4 and Figure 5In some embodiments, the lower end of the sealing arc surface 41 and the upper end of the guiding arc surface 42 are smoothly transitioned. Preferably, by achieving a smooth transition between the lower end of the sealing arc surface 41 and the upper end of the guiding arc surface 42, the connection between the sealing arc surface 41 and the guiding arc surface 42 is made smoother and more natural, and sharp corners or mutations are avoided, thereby reducing stress concentration. In this way, when the guiding arc surface 42 contacts and cooperates with the liner 2 and guides the sealing arc surface 41 to abut against the inner wall of the liner 2, stress concentration can be avoided at the connection between the sealing arc surface 41 and the guiding arc surface 42, thereby improving the overall strength and service life of the sealing ring 4, and at the same time reducing the friction and wear between the connection between the sealing arc surface 41 and the guiding arc surface 42 and the liner 2, ensuring that the sealing arc surface 41 is tightly fitted with the inner wall of the liner 2, forming a good sealing effect.

[0034] See Figure 3 、 Figure 4 、 Figure 5 and Figure 8 In some embodiments, one end of the sealing arc surface 41 away from the guide arc surface 42 extends outward to form a sealing slope 43, and the upper end of the inner pot 2 is provided with a edging portion 21; when the upper cover 3 is covered on the upper end of the pot body 1, the sealing slope 43 abuts against the edging portion 21. Preferably, when the upper cover 3 is placed on the upper end of the pot body 1, the sealing ring 4 moves synchronously with the upper cover 3, first contacting and cooperating with the transition arc surface 22 through the guide arc surface 42, and guiding the sealing arc surface 41 to abut against the inner wall of the inner pot 2 under the cooperation of the guide arc surface 42 and the transition arc surface 22. As the upper cover 3 and the pot body 1 are completely covered, the sealing arc surface 41 fits tightly with the inner wall of the inner pot 2 to form a first seal. At the same time, the sealing inclined surface 43 fits tightly with the edging portion 21 to form a second seal, thereby achieving a double seal between the sealing ring 4 and the inner pot 2, thereby driving the inner pot 2 with the edging portion 21 and the sealing ring 4 to form a good sealing effect, preventing air leakage, and ensuring that the inner pot 2 retains enough moisture during cooking, thereby enhancing the moisture content and taste of the food.

[0035] See Figure 3 、 Figure 4 、 Figure 5 and Figure 8In some embodiments, a transition arc surface 22 is further included, and the transition arc surface 22 is connected between the upper end of the inner pot 2 and the edging portion 21. Preferably, the transition arc surface 22 is used to realize an arc transition between the upper end of the inner pot 2 and the edging portion 21, effectively avoiding quality problems such as warping and deformation of the product, thereby improving the stability and reliability of the product, and reducing resistance. When the upper cover 3 is placed on the upper end of the pot body 1, the sealing arc surface 41 and the guide arc surface 42 are in contact with the transition arc surface 22 in turn, and move relative to the transition arc surface 22, so that the sealing arc surface 41 and the guide arc surface 42 and the transition arc surface 22 can be reduced. The friction between them can reduce the friction and wear between the components, making the movement of the sealing arc surface 41 and the guide arc surface 42 smoother. The transition arc surface 22 can guide the movement of the sealing arc surface 41 and the guide arc surface 42, so that the sealing arc surface 41 and the guide arc surface 42 can be assembled and positioned more accurately, thereby reducing the assembly error between the sealing arc surface 41 and the inner wall of the liner 2, ensuring that the sealing arc surface 41 is tightly fitted with the upper end of the liner 2, and forming a good sealing effect.

[0036] See Figure 3 、 Figure 4 、 Figure 5 and Figure 8 In some embodiments, the sealing arc surface 41 is a concave arc structure that cooperates with the transition arc surface 22. Preferably, when the upper cover 3 is placed on the upper end of the pot body 1, the sealing ring 4 moves synchronously with the upper cover 3, first contacting and cooperating with the transition arc surface 22 via the guide arc surface 42. Under the cooperation of the guide arc surface 42 and the transition arc surface 22, the sealing arc surface 41 is guided to abut against the transition arc surface 22 at the upper end of the inner pot 2. As the upper cover 3 and the pot body 1 are completely covered, the sealing arc surface 41 with a concave arc structure cooperates with the transition arc surface 22 at the upper end of the inner pot 2, and the sealing arc surface 41 and the transition arc surface 22 are tightly fitted, forming a good sealing effect, thereby driving the inner pot 2 with the edge portion 21 to tightly fit with the sealing ring 4, forming a good sealing effect, preventing air leakage, ensuring that the inner pot 2 retains sufficient moisture during cooking, and enhancing the moisture content and taste of the food.

[0037] In some embodiments, the guide arc surface 42, the sealing arc surface 41, and the sealing bevel 43 are integrally formed. Preferably, by integrally forming the guide arc surface 42, the sealing arc surface 41, and the sealing bevel 43, the continuity and integrity of the sealing ring 4 are ensured, thereby effectively preventing gas or liquid leakage. At the same time, the sealing ring 4 has greater structural strength and stability, which can ensure a long-lasting and stable sealing effect.

[0038] See Figure 2 、 Figure 3 and Figure 6 In some embodiments, a middle ring 5 is further included, and the middle ring 5 is detachably connected to the upper cover 3, and the sealing ring 4 is assembled on the middle ring 5. Optionally, a slot is provided at one end of the upper cover 3, and a buckle is provided at the other end of the upper cover 3. A block is provided at one end of the middle ring 5 to cooperate with the slot, and a card is provided at the other end of the middle ring 5 to cooperate with the buckle. During assembly, the card block is first inserted into the slot, and the middle ring 5 is driven to rotate around the card block so that the card and the buckle are engaged, thereby completing the assembly of the middle ring 5 and the upper cover 3. During disassembly, the card is driven to disengage from the buckle, and then the card block is pulled out of the slot. Preferably, the sealing ring 4 is assembled on the middle ring 5 by means of sleeve installation, pasting, snapping, etc., and is connected to the upper cover 3 through the middle ring 5, so that the sealing ring 4 is assembled on the upper cover 3. In this embodiment, the middle ring 5 is detachably connected to the upper cover 3. In this way, the sealing ring 4 can be separated from the upper cover 3 by removing the middle ring 5 from the upper cover 3, which is convenient for comprehensive cleaning of the sealing ring 4, preventing residual food from affecting the seal formed between the sealing ring 4 and the inner pot 2, and at the same time ensuring the hygiene of the sealing ring 4.

[0039] See Figure 2 、 Figure 3 and Figure 7 In some embodiments, a heat preservation plate 6 is further included, and the heat preservation plate 6 is nested in the middle ring 5. Preferably, the heat preservation plate 6 is nested in the inner circle of the middle ring 5, that is, the middle ring 5 is arranged on the outer peripheral side of the heat preservation plate 6, so that the heat preservation plate 6 is driven to be arranged opposite to the inner pot 2. In this way, after the cooking device finishes cooking, the heat preservation plate 6 can keep the food in the inner pot 2 warm to prevent the food from cooling down too early. At the same time, the heat preservation plate 6 can effectively prevent the volatilization of moisture, so that the food maintains a certain humidity and tenderness, and tastes more delicious. Furthermore, since the middle ring 5 is detachably connected to the upper cover 3, the heat preservation plate 6 can be separated from the upper cover 3 by removing the middle ring 5 from the upper cover 3, which is convenient for comprehensive cleaning of the heat preservation plate 6 and ensures the hygiene of the heat preservation plate 6.

[0040] See Figure 3 、 Figure 4 and Figure 5In some embodiments, the sealing ring 4 is provided with a rib 44, which is provided between the insulation plate 6 and the middle ring 5. Preferably, by providing the rib 44 between the insulation plate 6 and the middle ring 5, a seal is formed at the abutment between the insulation plate 6 and the middle ring 5, thereby preventing air leakage at the abutment between the insulation plate 6 and the middle ring 5 and optimizing the overall sealing effect of the cooking device. Optionally, a first groove structure is provided at the upper end of the rib 44, the opening of the first groove structure is downward, and a corresponding protrusion 45 structure is provided at the end of the middle ring 5 away from the inner liner 2, the rib 44 abuts against the inner ring of the middle ring 5, and the first groove structure is sleeved on the outside of the protrusion 45 structure, so that the sealing ring 4 can be reliably assembled on the middle ring 5, optionally, a second groove structure is provided on the peripheral side of the insulation board 6, and a snap fastener is provided on the outer edge of the second groove structure, and the middle ring 5 is provided with a snap hole. During assembly, the second groove structure is sleeved on the outside of the first groove structure, and the snap fastener is driven to snap-connect with the snap hole, so that the rib 44 is provided between the insulation board 6 and the middle ring 5, and the insulation board 6 is nested in the inner ring of the middle ring 5, ensuring that the rib 44, the insulation board 6 and the middle ring 5 form a reliable connection, effectively preventing air leakage at the abutment between the insulation board 6 and the middle ring 5.

[0041] See Figure 3 、 Figure 4 and Figure 5 In some embodiments, a protrusion 45 is provided on the side of the rib 44 close to the insulation board 6, and the protrusion 45 abuts against the end of the insulation board 6 close to the guide arc surface 42. Preferably, the upper end of the protrusion 45 abuts against the lower end of the insulation board 6. In this way, the protrusion 45 blocks the abutment between the rib 44 and the insulation board 6, further preventing water vapor from invading the abutment between the rib 44 and the insulation board 6, and optimizing the sealing effect of the upper cover 3.

[0042] See Figure 2-Figure 8In some embodiments, when the upper cover 3 is placed on the upper end of the pot body 1, the sealing ring 4 moves synchronously with the upper cover 3, first contacting and cooperating with the transition arc surface 22 through the guide arc surface 42, and guiding the sealing arc surface 41 to abut against the transition arc surface 22 at the upper end of the inner pot 2 under the cooperation of the guide arc surface 42 and the transition arc surface 22. As the upper cover 3 and the pot body 1 are completely covered, the sealing arc surface 41 and the transition arc surface 22 are tightly fitted to form a first seal. At the same time, the sealing inclined surface 43 and the edging portion 21 are tightly fitted to form a second seal, thereby achieving a double seal between the sealing ring 4 and the inner pot 2, thereby driving the inner pot 2 with the edging portion 21 to be sealed. The sealing ring 4 forms a good sealing effect to prevent air leakage. Furthermore, at this time, the insulation plate 6 of the upper cover 3 is arranged opposite to the inner pot 2. In this way, after the cooking device completes cooking, the insulation plate 6 can keep the food in the inner pot 2 warm to prevent the food from cooling down too early. At the same time, the insulation plate 6 can effectively prevent the volatilization of moisture. Furthermore, by arranging the rib 44 between the insulation plate 6 and the middle ring 5, a seal is formed at the junction between the insulation plate 6 and the middle ring 5 to prevent air leakage at the junction between the insulation plate 6 and the middle ring 5, thereby optimizing the overall sealing effect of the cooking device, fully ensuring that the inner pot 2 can retain enough moisture, and enhancing the moisture content and taste of the food.
