Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, specifically to an exhaust pipe, a top cover, and a cooking utensil. Background Technology

[0002] An electric pressure cooker is a kitchen appliance that combines the advantages of a pressure cooker and a rice cooker. It increases internal pressure, thus accelerating cooking and making food cook faster and more thoroughly.

[0003] In related technologies, electric pressure cookers are equipped with an anti-clogging nut and an anti-clogging cover at the lower end of the exhaust pipe to prevent food residue and other foreign objects from clogging the exhaust pipe and ensure the safe operation of the electric pressure cooker. Specifically, the anti-clogging nut is fixed to the exhaust pipe via threads, and the anti-clogging cover is fixed to the lower end of the exhaust pipe via clips. The anti-clogging nut and the anti-clogging cover work together to form a double anti-clogging structure, which can improve the anti-clogging performance of the electric pressure cooker.

[0004] However, the dual anti-clogging structure using an anti-clogging nut and an anti-clogging cover in related technologies has the following drawbacks: the anti-clogging cover requires additional clamps for fixation, which increases the number of parts in the assembly process. On the production line, more parts mean more complex assembly processes, requiring more manpower, resources, and time for assembly and debugging, thus reducing production efficiency. Furthermore, these additional parts also increase product costs, including raw material costs, processing costs, and the potential for increased defect rates due to assembly complexity. Utility Model Content

[0005] This invention provides an exhaust pipe, a top cover, and a cooking appliance to solve the problem of numerous and costly assembly parts in anti-clogging structures in related technologies.

[0006] According to one aspect of the present invention, an exhaust pipe is provided, the exhaust pipe having an exhaust hole that extends through in the vertical direction, the exhaust pipe including an anti-blocking connecting section and a flat section, the upper end of the flat section being connected to the lower end of the anti-blocking connecting section, the exhaust pipe having an anti-blocking groove communicating with the exhaust hole, the anti-blocking groove penetrating the side wall of the anti-blocking connecting section and the side wall of the flat section.

[0007] By applying the technical solution of this utility model, the anti-clogging component connecting section of the exhaust pipe can connect to the anti-clogging component, which can act as the first layer of anti-clogging structure. Since the exhaust pipe has an anti-clogging groove communicating with the exhaust port, and this groove penetrates the sidewall of the anti-clogging component connecting section and the sidewall of the flat section, the exhaust channel area of ​​the exhaust pipe can be increased, making it less prone to clogging. In other words, the anti-clogging groove designed into the exhaust pipe itself can act as the second layer of anti-clogging structure. Through the above structure, the anti-clogging component and the exhaust pipe work together to form a double anti-clogging structure, improving the anti-clogging performance of the electric pressure cooker. Compared to the double anti-clogging structure in related technologies that uses an anti-clogging nut and an anti-clogging cover, this application simplifies the two anti-clogging components (anti-clogging nut and anti-clogging cover) into a single anti-clogging component, thereby reducing the number of assembly parts and lowering costs.

[0008] Furthermore, the leveling section has two functions: First, when the cooking appliance is venting, the anti-clogging groove on the leveling section always exerts pressure on the anti-clogging component connecting section, preventing strip-shaped food from getting tangled on the anti-clogging component connecting section and thus preventing blockage of the vent pipe; Second, the leveling section can prevent strip-shaped food from getting tangled on the vent pipe.

[0009] Furthermore, the diameter of the leveling section is less than or equal to the diameter of the anti-clogging component connecting section; and / or, the surface of the leveling section is smooth. On the one hand, when the anti-clogging component is assembled onto the anti-clogging component connecting section, the leveling section will not interfere with the anti-clogging component; on the other hand, the fact that the diameter of the leveling section is less than or equal to the diameter of the anti-clogging component connecting section and the surface of the leveling section is smooth makes it less likely for strip-shaped food to get tangled in the leveling section.

[0010] Furthermore, the outer wall of the anti-clogging component connecting section is provided with external threads. The anti-clogging component connecting section can be threadedly connected to the anti-clogging component via the external threads, which has the advantages of simple assembly structure and firm assembly.

[0011] Furthermore, the upper end of the anti-clogging groove is flush with the upper end of the external thread, or the upper end of the anti-clogging groove is higher than the upper end of the external thread. Even when the anti-clogging component does not completely cover the external thread, the anti-clogging groove can effectively prevent food from clogging the vent hole, improving the anti-clogging performance of the vent pipe. Alternatively, the anti-clogging groove can still provide good anti-clogging performance after the anti-clogging component is removed.

[0012] Furthermore, the length of the leveling section is L, where 2mm ≤ L ≤ 10mm. By controlling the length of the leveling section, the anti-clogging effect and exhaust efficiency are balanced, ensuring smooth exhaust while minimizing the entanglement of long food items.

[0013] Furthermore, the width of the anti-clogging groove is D, where 1mm ≤ D ≤ 5mm; and / or, the width of the anti-clogging groove remains constant in the vertical direction. By setting a reasonable groove width, the anti-clogging effect and structural strength are balanced, and the entanglement of strip-shaped food is prevented to the greatest extent possible while ensuring structural strength.

[0014] Furthermore, the anti-clogging groove penetrates the sidewalls of the anti-clogging component connecting section and the flat section on both sides of the exhaust pipe in the radial direction; and / or, the anti-clogging groove extends from one side of the lower end face of the flat section to the other side in the radial direction of the exhaust pipe. With the above structure, the anti-clogging groove has a larger area, resulting in a better anti-clogging effect.

[0015] Furthermore, the lower end of the leveling section is provided with rounded corners or chamfers; and / or, the lower end of the leveling section is the lower end of the exhaust pipe, and the anti-clogging groove penetrates through the lower end surface of the leveling section. The rounded corners or chamfers reduce the adhesion of food to the lower end of the exhaust pipe, making it easier for food to slide off and preventing blockages, and also making it less likely for strip-shaped foods to become entangled in the leveling section. Moreover, since the lower end of the leveling section is the lower end of the exhaust pipe, the anti-clogging groove penetrating through the lower end surface of the leveling section further optimizes the effect of the leveling section in preventing strip-shaped foods from becoming entangled in the exhaust pipe.

[0016] According to another aspect of this utility model, a top cover is provided, comprising a cover body, an exhaust pipe, a pressure limiting valve, and an anti-clogging component. The exhaust pipe is disposed on the cover body, the pressure limiting valve is disposed at the upper end of the exhaust pipe, and the anti-clogging component is connected to the anti-clogging component connecting section of the exhaust pipe and surrounds the outside of the flat section of the exhaust pipe. The exhaust pipe is the exhaust pipe provided above. Therefore, this top cover can also simplify the two anti-clogging components, the anti-clogging nut and the anti-clogging cover, in the related art into a single anti-clogging component, thereby reducing the number of assembly parts of the anti-clogging structure and lowering costs. Furthermore, the flat section not only prevents strip-shaped food from wrapping around the anti-clogging component connecting section, thus preventing blockage of the exhaust pipe, but also prevents strip-shaped food from wrapping around the exhaust pipe.

[0017] Furthermore, the anti-clogging component includes an anti-clogging nut. The anti-clogging nut and the exhaust pipe work together to form a double anti-clogging structure, which can improve the anti-clogging performance of the electric pressure cooker.

[0018] According to another aspect of this utility model, a cooking appliance is provided, comprising: a pot body; and a lid, which is detachably and closably disposed on the pot body, the lid being the one provided above. Therefore, this cooking appliance can also simplify the two anti-clogging components—the anti-clogging nut and the anti-clogging cover—into a single anti-clogging component in related technologies, thereby reducing the number of assembly parts in the anti-clogging structure and lowering costs. Furthermore, the flat section prevents strip-shaped food from tangling around the connecting section of the anti-clogging component, thus preventing blockage of the exhaust pipe, and also prevents strip-shaped food from tangling around the exhaust pipe.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0041] like Figures 1 to 3 As shown, this utility model embodiment provides an exhaust pipe with an exhaust hole 10 that extends through the pipe in the vertical direction. The exhaust pipe includes an anti-blocking connecting section 20 and a flat section 30. The upper end of the flat section 30 is connected to the lower end of the anti-blocking connecting section 20. The exhaust pipe has an anti-blocking groove 40 that communicates with the exhaust hole 10. The anti-blocking groove 40 penetrates the side wall of the anti-blocking connecting section 20 and the side wall of the flat section 30.

[0042] Using the exhaust pipe provided in this embodiment, the anti-clogging connecting section 20 of the exhaust pipe can connect to the anti-clogging component 80, which functions as the first layer of anti-clogging structure. Since the exhaust pipe has an anti-clogging groove 40 that communicates with the exhaust port 10, and the anti-clogging groove 40 penetrates the side wall of the anti-clogging connecting section 20 and the side wall of the flat section 30, the exhaust channel area of ​​the exhaust pipe can be increased, making it less prone to clogging. In other words, the anti-clogging groove 40 designed into the exhaust pipe itself functions as the second layer of anti-clogging structure. Through the above structure, the anti-clogging component 80 and the exhaust pipe together form a double anti-clogging structure, improving the anti-clogging performance of the electric pressure cooker. Compared to the double anti-clogging structure in related technologies that uses an anti-clogging nut and an anti-clogging cover, this application simplifies the two anti-clogging components (anti-clogging nut and anti-clogging cover) into a single anti-clogging component, thereby reducing the number of assembly parts and lowering costs.

[0043] Furthermore, the flat section 30 has two functions: First, when the cooking appliance is venting, the anti-clogging groove 40 on the flat section 30 always exerts pressure on the anti-clogging component connecting section 20 (which is an area prone to clogging), so that strip-shaped food cannot be wrapped around the anti-clogging component connecting section 20, thus preventing the exhaust pipe from being blocked; Second, the flat section 30 can prevent strip-shaped food from being wrapped around the exhaust pipe.

[0044] In addition, the inventors found that the size deviation of the claws in the related technology is large, which causes the anti-clogging cover to be stuck or too loose. If it is stuck, it will be difficult for consumers to remove the anti-clogging cover for cleaning. If it is too loose, the anti-clogging cover will easily fall out during normal cooking, affecting the consumer experience. However, this application does not have the above problems.

[0045] It should be noted that strip-shaped foods refer to long and thin foods, such as kelp or bean curd sheets.

[0046] In this embodiment, the surface of the flattening section 30 is a smooth surface. Here, "smooth surface" means that the surface roughness of the flattening section 30 is Ra, where 0 μm < Ra ≤ 12.5 μm. In this embodiment, 0.5 μm ≤ Ra ≤ 12.5 μm.

[0047] In this embodiment, both the anti-clogging connecting section 20 and the flat section 30 are cylindrical structures. In other embodiments, protrusions or other structures can be provided on the flat section 30 (for example, the protrusions smoothly transition to the sidewall of the flat section 30), as long as the surface of the flat section 30 is smooth, the flat section 30 can prevent strip-shaped food from getting tangled at the lower end of the exhaust pipe.

[0048] The diameter of the leveling section 30 is less than or equal to the diameter of the anti-blocking component connecting section 20. On the one hand, when the anti-blocking component 80 is assembled onto the anti-blocking component connecting section 20, the leveling section 30 will not interfere with the anti-blocking component 80; on the other hand, the fact that the diameter of the leveling section 30 is less than or equal to the diameter of the anti-blocking component connecting section 20 makes it less likely for the leveling section 30 to entangle strip-shaped food.

[0049] In this embodiment, the diameter of the flattening section 30 is smaller than the diameter of the anti-blocking component connecting section 20.

[0050] like Figure 1 As shown, the outer wall of the anti-blocking component connecting section 20 is provided with an external thread 21. The anti-blocking component connecting section 20 can be threadedly connected to the anti-blocking component 80 through the external thread 21, which has the advantages of simple assembly structure and firm assembly.

[0051] The upper end of the anti-clogging groove 40 is flush with the upper end of the external thread 21, or the upper end of the anti-clogging groove 40 is higher than the upper end of the external thread 21. Even when the anti-clogging component 80 does not completely cover the external thread 21, the anti-clogging groove 40 can effectively prevent food from clogging the vent hole, thus improving the anti-clogging performance of the vent pipe. Alternatively, the anti-clogging groove 40 can still provide a good anti-clogging effect after the anti-clogging component 80 is removed.

[0052] In this embodiment, the upper end of the anti-clogging groove 40 is flush with the upper end of the external thread 21.

[0053] like Figure 2 As shown, the length of the leveling section 30 is L, where 2mm ≤ L ≤ 10mm. By controlling the length of the leveling section 30, the anti-clogging effect and exhaust efficiency are balanced, ensuring smooth exhaust while minimizing the entanglement of strip-shaped foods.

[0054] Wherein, L can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or other values ​​between 2mm and 10mm. In this embodiment, L is 3mm.

[0055] like Figure 2 As shown, the width of the anti-clogging groove 40 is D, where 1mm ≤ D ≤ 5mm. The width of the anti-clogging groove 40 remains constant in the vertical direction. By setting a reasonable groove width, the anti-clogging effect and structural strength are balanced, and the entanglement of strip-shaped food is prevented to the greatest extent possible while ensuring structural strength.

[0056] Where D can be 1mm, 2mm, 3mm, 4mm, 5mm, or other values ​​between 1mm and 5mm. In this embodiment, D is 2mm.

[0057] In this embodiment, the anti-clogging groove 40 penetrates the sidewalls of the anti-clogging component connecting section 20 and the flat section 30 on both sides of the exhaust pipe in the radial direction, and the anti-clogging groove 40 extends from one side of the lower end face of the flat section 30 to the other side in the radial direction of the exhaust pipe. With the above structure, the anti-clogging groove 40 has a larger area and can achieve a better anti-clogging effect.

[0058] The lower end of the flat section 30 is provided with a rounded corner 31 or a chamfer. The design of the rounded corner 31 or chamfer can reduce the adhesion of food to the lower end of the exhaust pipe, making it easier for food to slide off and preventing blockage. In addition, the flat section 30 is less likely to entangle strip-shaped food.

[0059] In this embodiment, the lower end of the flat section 30 is provided with a rounded corner 31.

[0060] Specifically, in this embodiment, the lower end of the flattening section 30 is the lower end of the exhaust pipe, and the anti-clogging groove 40 penetrates the lower end surface of the flattening section 30 to further optimize the effect of the flattening section 30 in preventing strip-shaped food from getting tangled on the exhaust pipe.

[0061] like Figures 3 to 8 As shown, another embodiment of this utility model provides a top cover, which includes a cover body 50, an exhaust pipe 60, a pressure limiting valve 70, and an anti-blocking component 80. The exhaust pipe 60 is disposed on the cover body 50, the pressure limiting valve 70 is disposed at the upper end of the exhaust pipe 60, and the anti-blocking component 80 is connected to the anti-blocking component connecting section 20 of the exhaust pipe 60 and surrounds the outside of the flat section 30 of the exhaust pipe 60. The exhaust pipe 60 is the exhaust pipe provided above. Therefore, this top cover can also simplify the two anti-blocking components, the anti-blocking nut and the anti-blocking cover, in the related technology into a single anti-blocking component, thereby reducing the number of assembly parts of the anti-blocking structure and reducing costs. Furthermore, the flat section 30 can prevent strip-shaped food from getting tangled on the anti-blocking component connecting section 20, thus preventing blockage of the exhaust pipe 60, and the flat section 30 can also prevent strip-shaped food from getting tangled on the exhaust pipe 60.

[0062] In this embodiment, the anti-clogging component 80 includes an anti-clogging nut 81. The anti-clogging nut 81 and the exhaust pipe 60 work together to form a double anti-clogging structure, which can improve the anti-clogging performance of the electric pressure cooker.

[0063] Specifically, the exhaust pipe 60 passes through the flat gasket 91 and the cover 50. The lower end of the exhaust pipe 60 is sequentially equipped with a sealing ring 92, a concave gasket 93, a spring gasket 94, and an anti-blocking nut 81. The exhaust pipe 60 is fixed to the anti-blocking nut 81 by the external thread 21 on the exhaust pipe 60. The pressure relief valve 70 is installed at the upper end of the exhaust pipe 60.

[0064] Another embodiment of this utility model provides a cooking appliance, which includes a pot body and a lid. The lid is detachably mounted on the pot body and is the same as the lid provided above. Therefore, this cooking appliance can also simplify the two anti-clogging components, the anti-clogging nut and the anti-clogging cover, in related technologies into a single anti-clogging component, thereby reducing the number of assembly parts of the anti-clogging structure and lowering costs. Furthermore, the flat section 30 prevents strip-shaped food from getting tangled on the anti-clogging component connecting section 20, thus preventing blockage of the exhaust pipe 60, and also prevents strip-shaped food from getting tangled on the exhaust pipe 60.

[0065] Cooking appliances include, but are not limited to, electric pressure cookers and multi-functional cookers.
