Description

Technical Field

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

[0002] In related technologies, to ensure safe use, a device is generally installed to prevent forced opening of the lid when there is pressure inside the pot. This device includes a stop-opening element on the lid and a stop-opening rod that can engage with the stop-opening element. When there is pressure inside the pot, the stop-opening rod rises and engages with the stop-opening rod, preventing the lid from rotating.

[0003] In the related technology, the stop-opening component and the outer surface of the pot teeth are in point contact, resulting in low limiting resistance for the stop-opening component. If the pressure inside the pot is not completely released, the lid can be opened if the user forcibly opens it, which may easily injure the user. Utility Model Content

[0004] The main purpose of this utility model is to provide a cooking appliance to solve the problem in related technologies where the limiting resistance of the stop-opening component is small, and the lid can be opened when the user forcibly opens the lid.

[0005] To achieve the above objectives, according to one aspect of the present invention, a cooking utensil is provided, comprising: a pot body; a pot tooth provided on the pot body; a lid body, which is closable and can be placed on the pot body, and a stop-opening member is provided on the lid body, the lid body can be locked in engagement with the pot tooth, and the stop-opening member can abut against the outer surface of the pot tooth; wherein, the stop-opening member has an abutting surface, and the abutting surface is in line contact or surface contact with the outer surface of the pot tooth.

[0006] By applying the technical solution of this utility model, the contact surface of the stop-opening component is designed to have line or surface contact with the outer surface of the pot teeth, thereby enhancing the limiting effect of the stop-opening component on the lid. When pressure is present inside the pot, compared to the point contact between the stop-opening component and the outer surface of the pot teeth in related technologies, the contact surface of the stop-opening component forms a larger contact area with the outer surface of the pot teeth. This allows the stop-opening component to withstand greater force when preventing the lid from rotating, increasing the limiting resistance and effectively preventing the user from forcibly opening the lid before the pressure is completely released. Therefore, the technical solution of this application can solve the problem of the relatively small limiting resistance of the stop-opening component in related technologies, which allows the lid to be opened when the user forcibly tries to open it.

[0007] Furthermore, the contact surface includes a curved surface that makes line contact with the outer surface of the pot teeth. When there is pressure inside the pot, the curved surface maintains line contact with the outer surface of the pot teeth, which improves the stability of the stop-opening component in preventing the lid from rotating and enhances the limiting effect.

[0008] Furthermore, the projection of the curved surface along the vertical contour of the outer side of the pot teeth onto the bottom surface of the pot body is a semicircle. The semicircular projection design of the curved surface ensures that the contact line maintains a consistent contact state with the outer side of the pot teeth throughout the entire operation, ensuring a stable limiting effect even under the force of forcibly opening the lid and preventing the lid from opening accidentally.

[0009] Furthermore, a contact line is formed on the curved surface to make line contact with the outer surface of the pot teeth. The contact line is parallel to or inclined to the vertical line of the pot body. Under the force of forcibly opening the lid, because the contact line is parallel to the vertical line of the pot body, it ensures that the curved surface can reliably contact the outer surface of the pot teeth, thus ensuring a stable limiting effect.

[0010] Furthermore, a contact line is formed on the curved surface to contact the outer side line of the pot teeth. The length of the contact line is greater than or equal to 2 mm and less than or equal to 5 mm. The setting of the contact line length range ensures sufficient contact area to provide a stable limiting effect, while also ensuring smooth opening of the lid.

[0011] Furthermore, the contact surface includes a plane that contacts the outer surface of the pot teeth. This surface-to-surface contact design between the plane and the outer surface of the pot teeth further increases the contact area and enhances the limiting resistance of the stop element on the lid. This allows the stop element to more effectively prevent the lid from rotating when pressure is present inside the pot, thus enhancing safety.

[0012] Furthermore, the stop-opening component also has an annular arc surface surrounding the outer side of the plane, which connects to the edge of the plane. During the locking or unlocking process between the lid and the pot teeth, the annular arc surface facilitates sliding along the outer side of the pot teeth, allowing the lid to open or close smoothly.

[0013] Furthermore, a contact surface is formed on the plane to make surface contact with the outer surface of the pot tooth, and the area of ​​the contact surface is greater than or equal to 3 mm². 2 And less than or equal to 15mm 2 The contact area is designed to ensure that the contact between the stop and the pot teeth is large enough when the pot is under pressure, providing a reliable limiting effect. At the same time, it avoids the contact area being too large, which would increase the resistance to opening the lid and affect the user experience.

[0014] Furthermore, the contact surface is located at the end of the stopper facing the pot body, or on the side of the end of the stopper facing the pot body. Having the contact surface at the end or on both sides of the end of the stopper ensures a more direct and stable contact between the stopper and the outer surface of the pot teeth. When the pot body is under pressure, the contact surface at the end of the stopper or on both sides can immediately form an effective abutment with the outer surface of the pot teeth, preventing accidental rotation of the lid.

[0015] Furthermore, the contact surface includes at least two surfaces, which are arranged sequentially along the circumference of the pot body, and each contact surface can abut against the outer surface of the pot teeth. When the pot body is under pressure, each contact surface can independently abut against the outer surface of the pot teeth, thereby providing limiting force at different points and greatly enhancing the ability of the stop-opening component to prevent the lid from rotating.

[0029] 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.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] This application provides a cooking utensil, such as Figures 1 to 5As shown, Embodiment 1 of the cooking utensil includes a pot body 10 and a lid 20. The pot body 10 has a serrated edge 11. The lid 20 is closable and covers the pot body 10. The lid 20 has a locking element 30, which locks into the serrated edge 11 and abuts against the outer surface of the serrated edge 11. The locking element 30 has an abutting surface 321 that contacts the outer surface of the serrated edge 11.

[0033] The technical solution of Embodiment 1 of the cooking appliance enhances the limiting effect of the stopper 30 on the lid 20 by designing the abutment surface 321 of the stopper 30 to have line contact with the outer surface of the pot teeth 11. When pressure exists inside the pot body 10, compared to the point contact between the stopper and the outer surface of the pot teeth in related technologies, the abutment surface 321 of the stopper 30 forms a larger contact area with the outer surface of the pot teeth 11. This allows the stopper 30 to withstand greater force when preventing the lid 20 from rotating, increasing the limiting resistance and effectively preventing the user from forcibly opening the lid before the pressure is completely released. Therefore, the technical solution of Embodiment 1 of the cooking appliance solves the problem of the relatively small limiting resistance of the stopper in related technologies, which allows the lid to be opened when the user forcibly tries to open it.

[0034] like Figures 1 to 5 As shown, the contact surface 321 includes a curved surface 322 that makes line contact with the outer surface of the pot tooth 11. When there is pressure inside the pot body 10, the curved surface 322 maintains line contact with the outer surface of the pot tooth 11, which improves the stability of the stop-opening member 30 in preventing the lid 20 from rotating and enhances the limiting effect. The curved surface 322 can be a circular arc surface or an elliptical surface.

[0035] like Figures 1 to 5 As shown, the projection of the curved surface 322 along the vertical contour surface 12 of the outer side of the pot tooth 11 onto the bottom surface of the pot body 10 is a semicircle. The semicircular projection design of the curved surface 322 ensures that the contact line 323 maintains a consistent contact state with the outer side of the pot tooth 11 throughout the entire operation, ensuring a stable limiting effect even under the force of forcibly opening the lid and preventing the lid 20 from opening accidentally.

[0036] like Figures 1 to 5 As shown, a contact line 323 is formed on the curved surface 322, making line contact with the outer surface of the pot tooth 11. The contact line 323 is parallel to the vertical line 13 of the pot body 10 on the outer surface of the pot tooth 11. Under the force of forcibly opening the lid, because the contact line 323 is parallel to the vertical line 13 of the pot body 10 on the outer surface of the pot tooth 11, the curved surface 322 can reliably contact the outer surface of the pot tooth 11, ensuring a stable limiting effect. It should be noted that the contact line 323 mentioned above refers to the contact line generated when the curved surface 322 makes line contact with the outer surface of the pot tooth 11, and does not actually exist in the solid structure of the curved surface 322.

[0037] In other embodiments, the contact line 323 is inclined to the vertical line 13 of the pot body 10 on the outer side of the pot tooth 11.

[0038] like Figures 1 to 5 As shown, a contact line 323 is formed on the curved surface 322, which contacts the outer surface line of the pot tooth 11. The length of the contact line 323 is greater than or equal to 2 mm and less than or equal to 5 mm. The setting of the length range of the contact line 323 ensures sufficient contact area to provide a stable limiting effect, while also ensuring smooth opening of the lid.

[0039] The length of the contact wire 323 is preferably 2mm, 3mm, 4mm, or 5mm.

[0040] In Example 2 of the cooking appliance, such as Figures 6 to 8 As shown, the difference from Embodiment 1 of the cooking appliance is that the contact surface 321 contacts the outer surface of the pot tooth 11. In Embodiment 2 of the cooking appliance, the contact surface 321 includes a plane 324 that contacts the outer surface of the pot tooth 11. The surface contact design between the plane 324 and the outer surface of the pot tooth 11 further increases the contact area and improves the limiting resistance of the stop member 30 to the lid 20. This allows the stop member 30 to more effectively prevent the lid 20 from rotating when pressure is present inside the pot body 10, thus enhancing safety.

[0041] Plane 324 is preferably circular, but in other embodiments not shown, the plane may be square, elliptical, or polygonal.

[0042] like Figures 6 to 8 As shown, the stop-opening member 30 also has an annular arc surface 326 surrounding the outer side of the plane 324, and the annular arc surface 326 is connected to the edge of the plane 324. During the locking or unlocking process between the cover 20 and the pot tooth 11, the annular arc surface 326 facilitates sliding along the outer side of the pot tooth 11, so that the cover 20 can be opened or closed smoothly.

[0043] like Figures 6 to 8 As shown, a contact surface 325 is formed on the plane 324 to make surface contact with the outer surface of the tooth 11, and the area of ​​the contact surface 325 is greater than or equal to 3 mm². 2 And less than or equal to 15mm 2 The contact area 325 is designed to ensure that when the pot body 10 is under pressure, the contact between the stop part 30 and the pot tooth 11 is large enough to provide a reliable limiting effect, while also avoiding an excessively large contact area that would increase the resistance to opening the lid and affect the user experience.

[0044] The area of ​​the contact surface 325 is preferably 3 mm². 2 Or 4mm 2 Or 6mm 2 Or 8mm2 Or 10mm 2 Or 12mm 2 Or 14mm 2 Or 15mm 2 .

[0045] The following test was conducted on the surface contact between the plane 324 and the outer side of the pot tooth 11: At 1.07 times the rated voltage, water of about 25 mm depth was added into the pot body, a pressure gauge was installed on the lid, and after the pressure in the pot body reached about 10 kPa, the power was disconnected, and the pressure in the pot body was allowed to cool naturally to 4 kPa. A force of 200 N was applied to the most unfavorable position of the lid or handle that could be gripped by hand using a push force gauge.

[0046] Under the action of a force of 200N, 280N, 290N, or 300N, due to the surface contact between the plane 324 and the outer side of the pot tooth 11, the stop part 30 prevents the lid from opening, the lid cannot be opened, and the lid or handle does not show any abnormalities such as cracking or breakage.

[0047] In this application, as Figures 1 to 8 As shown, the lid 20 includes an outer lid 21 and an inner lid 22 disposed inside the outer lid 21. The stop-opening member 30 includes a stop-opening plate 31 movably disposed on the inner lid 22 and a stop-opening head 32 disposed on the first end of the stop-opening plate 31. An abutment surface 321 is disposed on the stop-opening head 32. The inner lid 22 can lock into the pot teeth 11. The second end of the stop-opening plate 31 is provided with a stop-opening hole 33 that can engage with the stop-opening rod 40 of the cooking appliance. The aforementioned stop-opening plate 31 and stop-opening head 32 ensure that when the pot body 10 is under pressure, the stop-opening head 32 on the stop-opening plate 31 can lock into the pot teeth 11, and the engagement of the stop-opening hole 33 with the stop-opening rod 40 effectively locks the lid 20 onto the pot body 10, effectively preventing the user from forcibly opening the lid, thus enhancing the safety and operational reliability of the cooking appliance. The inner lid 22 is provided with a through hole for the stop-opening head 32 to pass through.

[0048] Specifically, when the pot body 10 is in a depressurized state, the stop rod 40 is not inserted into the stop hole 33, and the stop member 30 can open or close the lid along with the lid 20 without interfering with the opening or closing process of the lid 20. When the pot body 10 is in a pressurized state, the stop rod 40 is inserted into the stop hole 33, and the abutting surface 321 abuts against the outer side of the pot tooth 11. The stop member 30 prevents the lid 20 from opening, thus preventing the pot body 10 from being forcibly opened under pressure and improving safety.

[0049] like Figure 7 and Figure 8As shown, the contact surface 325 is located at the end of the stop-opening member 30 facing the pot body 10. The contact surface 325, located at the end or both sides of the end of the stop-opening member 30, ensures a more direct and stable contact between the stop-opening member 30 and the outer surface of the pot teeth 11. When the pot body 10 is under pressure, the end contact surface or the contact surfaces on both sides of the stop-opening member 30 can immediately form an effective abutment with the outer surface of the pot teeth 11, preventing accidental rotation of the lid 20.

[0050] In an embodiment not shown in the figure, the contact surface 325 is located on the side of the end of the stop member 30 facing the pot body 10.

[0051] like Figure 7 and Figure 8 As shown, the contact surface 325 includes at least two surfaces, which are arranged sequentially along the circumference of the pot body 10, and each contact surface 325 can abut against the outer surface of the pot tooth 11. The distribution of at least two contact surfaces along the circumference of the pot body 10 can significantly improve the limiting effect of the stop-opening member 30. When the pot body 10 is under pressure, each contact surface 325 can independently form an abutment with the outer surface of the pot tooth 11, thereby providing limiting force at different points and greatly enhancing the ability of the stop-opening member 30 to prevent the lid 20 from rotating.

[0052] It should be noted that when the pot body 10 is under pressure, the inner lid 22 will float up and move upward a certain distance relative to the pot body 10.

[0053] like Figures 1 to 5 As shown, the cover 20 also includes an elastic element 23 disposed between the outer cover 21 and the first end of the stop plate 31. The elastic element 23 applies an elastic force in the direction of the stop head 32. The elastic element 23 ensures a tighter and more reliable contact between the stop head 32 and the outer side of the pot tooth 11, that is, it ensures the reliability of the line contact or surface contact between the abutment surface 321 and the outer side of the pot tooth 11, and maintains a good limiting effect even when the force of forcibly opening the cover is increased. The elastic element 23 is preferably a spring.

[0054] The pot body 10 includes a shell and a heat insulation cover disposed within the shell, with multiple pot teeth disposed on the heat insulation cover. The inner cover 22 is provided with cover teeth that engage with the pot teeth for locking or unlocking.

[0055] It should be noted that in this application, "multiple" means two or more.

[0056] The cooking appliance in this application is a pressure cooker, but it can also be a rice cooker, slow cooker, frying machine, food processor, or other appliances with other functions.

[0057] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0058] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0059] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
