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 of a cooking appliance. 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] To improve the reliability of the device preventing forced opening of the lid, the related technology provides a limiting hole on the pot body and a limiting protrusion on the lid that can be inserted into the limiting hole. When the limiting protrusion is inserted into the limiting hole, it can effectively ensure that the lid cannot rotate.

[0004] However, the aforementioned limiting holes and limiting protrusions increase the number of processing steps, resulting in higher processing costs. Utility Model Content

[0005] The main purpose of this utility model is to provide a cooking utensil that solves the problem that the setting of limiting holes and limiting protrusions in related technologies increases the processing steps and makes the processing cost higher.

[0006] To achieve the above objectives, this utility model provides a cooking utensil, comprising: a pot body, on which multiple pot teeth are provided, spaced apart circumferentially along the pot body, one of which is a limiting tooth, having a first dimension between the limiting tooth and the vertical center line of the pot body, and at least one of the remaining pot teeth having a second dimension between it and the vertical center line of the pot body, the first dimension being larger than the second dimension; a lid, which is closable and can be locked with the limiting tooth, and a stop-opening rod is movably provided on the lid; and a stop-opening plate, movably provided on the lid, the first end of the stop-opening plate having a stop-opening head that abuts against the outer surface of the limiting tooth, and the second end of the stop-opening plate having a stop-opening hole that abuts against the stop-opening rod.

[0007] By applying the technical solution of this utility model, when the pot of the cooking utensil is under pressure, the stop rod floats up and engages with the stop hole. Because the first dimension is larger than the second dimension, the stop rod can more firmly abut against the outer surface of the limiting tooth, which helps increase the limiting resistance applied by the stop rod to the outer surface of the pot tooth, reduces the possibility of lateral movement of the stop plate, improves the reliability of preventing forced opening of the lid, and effectively ensures that the lid cannot rotate. Therefore, it eliminates the need for limiting holes or limiting protrusions in related technologies to achieve the stop function, optimizes the processing steps, and helps reduce processing costs. Thus, the technical solution of this application effectively solves the problem that the setting of limiting holes and limiting protrusions in related technologies increases processing steps and leads to higher processing costs.

[0008] Furthermore, along the inner to outer direction of the pot body, the outer contour of the limiting tooth has a first dimension with respect to the vertical center line, and at least one of the remaining pot teeth has a second dimension with respect to the vertical center line of the pot body. The difference between the first and second dimensions is greater than or equal to 0.5 mm and less than or equal to 1.5 mm. By controlling the difference between the first and second dimensions, the stop head can more precisely form an abutment fit with the limiting tooth. This not only increases the abutment force between the stop head and the limiting tooth, reducing lateral movement, but also improves the reliability of the stop-opening rod and the stop-opening hole, effectively preventing forced opening of the lid under pressure and increasing safety.

[0009] Furthermore, the wall of the stop-opening hole is provided with a limiting surface that engages with the stop-opening rod to restrict lateral movement of the stop-opening plate when it engages with the stop-opening rod. When the pot of the cooking appliance is pressurized, the stop-opening rod floats upward and engages with the stop-opening hole. The limiting surface engaging with the stop-opening rod restricts lateral movement of the stop-opening plate when it engages with the stop-opening rod, reducing the amount of swaying caused by the stop-opening plate under the force of forced opening, effectively improving the reliability of preventing forced opening.

[0010] Furthermore, the limiting surface protrudes from the wall of the stop hole in the axial direction of the stop hole; and / or, the limiting surface is a limiting inclined surface or a limiting curved surface. The above-mentioned setting of the limiting surface enhances the limiting effect between the stop rod and the stop plate, restricts the lateral movement of the stop plate and the stop rod under the limiting cooperation, reduces the amount of sway generated by the stop plate when subjected to the force of forced opening, improves the stability of the stop-opening cooperation, and effectively prevents forced opening.

[0011] Furthermore, the limiting surface is either a limiting inclined surface or a limiting curved surface. Using a limiting inclined surface or a limiting curved surface can reduce the gap between the stop rod and the stop plate during the stop-opening engagement, reduce the deflection of the stop plate, and ensure that the cover is firmly locked under pressure.

[0012] Furthermore, the limiting surface is located on the side adjacent to the end face of the second end of the stop hole and the stop plate. The above structure directly restricts the lateral movement of the stop plate by the limiting surface, reduces the sway of the stop plate, enhances the reliability of the stop-start engagement, and shortens the effective locking stroke of the stop hole under force.

[0013] Furthermore, the width of the end face of the stop hole near the second end of the stop plate is smaller than the width of the end face of the stop hole away from the second end of the stop plate. This narrower side near the second end of the stop plate allows for a more reliable limiting fit with the stop rod, reducing the swing of the stop rod within the stop hole. This further restricts the lateral movement of the stop plate and stop rod during engagement, enhancing the stability against forced opening and effectively avoiding safety risks during the use of cooking appliances.

[0014] Furthermore, in order to accommodate a first size that is larger than the second size, the set distance of the stop head extending towards the vertical center line of the pot body is greater than or equal to 9.3 mm and less than or equal to 10.3 mm.

[0015] Furthermore, the lid includes a top plate and side plates surrounding the edge of the top plate. The inner wall of the side plates is provided with protrusions that can abut against the pot's teeth. The protrusions can reduce the misalignment error in the front-to-back direction when the lid and the pot are locked together, so that the lid is more centered relative to the pot.

[0016] Furthermore, in order to further reduce the misalignment error in the front and rear directions when the lid and pot are locked together, so that the lid is in a more central position relative to the pot, the protrusion and stop are located on both sides of the side plate.

[0017] Furthermore, the side panel is provided with a lid tooth that mates with the pot tooth, with a protrusion located above the lid tooth. The protrusion, in conjunction with the lid tooth, optimizes the locking fit between the lid and the pot body, allowing the lid to engage more smoothly with the pot tooth when closed, and facilitating the lid to be easily centered relative to the pot body when closed.

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.

[0040] This application provides a cooking utensil, such as Figures 1 to 9As shown, the embodiment of the cooking appliance includes: a pot body 10, a lid 20, and a stop-opening plate 30. The pot body 10 is provided with multiple pot teeth 11, spaced apart circumferentially along the pot body 10. One of the pot teeth 11 is a limiting tooth 12, with a first dimension L2 between the limiting tooth 12 and the vertical center line L4 of the pot body 10. At least one of the remaining pot teeth 11 has a second dimension L3 between it and the vertical center line L4 of the pot body 10, where the first dimension L2 is larger than the second dimension L3. The lid 20 is closable on the pot body 10 and can be locked in place with the limiting tooth 12. A stop-opening rod 21 is movably provided on the lid 20. The stop plate 30 is movably disposed on the cover 20. The first end of the stop plate 30 is provided with a stop head 31 that can abut against the outer side of the limiting tooth 12, and the second end of the stop plate 30 is provided with a stop hole 32 that can stop and cooperate with the stop rod 21.

[0041] In the technical solution of the embodiment of the cooking appliance, under pressure inside the pot body 10, the stop rod 21 floats up and engages with the stop hole 32. Since the first dimension L2 is larger than the second dimension L3, the stop head 31 can more firmly abut against the outer surface of the limiting tooth 12. This increases the limiting resistance applied by the stop head 31 to the outer surface of the pot tooth 11, reduces the possibility of lateral movement of the stop plate 30, improves the reliability of preventing forced opening of the lid, and effectively ensures that the lid cannot rotate. Therefore, it eliminates the need for limiting holes or limiting protrusions in related technologies to achieve the stop function, optimizes the processing steps, and helps reduce processing costs. Thus, the technical solution of this embodiment of the cooking appliance effectively solves the problem that the setting of limiting holes and limiting protrusions in related technologies increases processing steps and leads to higher processing costs.

[0042] It should be noted that the aforementioned "second dimension" refers to the distance between the outer surface of at least one pot tooth 11 on the side opposite to the limiting tooth 12 on the pot body 10 and the vertical center line L4. The first dimension between the outer surface of the limiting tooth 12 and the vertical center line L4 of the pot body 10 can be equal or unequal in the circumferential direction of the pot body 10. When the first dimension is equal in the circumferential direction of the pot body 10, the outer surface of the limiting tooth 12 is located on the uniform outer circumference of the pot body 10; when the first dimension is unequal in the circumferential direction of the pot body 10, the outer surface of the limiting tooth 12 is located on the gradient outer circumference of the pot body 10.

[0043] like Figures 1 to 9As shown, along the direction from the inside to the outside of the pot body 10, the outer contour of the limiting tooth 12 has a first dimension L2 between it and the vertical center line L4, and the outer contour of at least one of the remaining pot teeth 11 has a second dimension L3 between it and the vertical center line L4 of the pot body 10. The difference between the first dimension L2 and the second dimension L3 is greater than or equal to 0.5 mm and less than or equal to 1.5 mm. By controlling the difference between the first dimension L2 and the second dimension L3, the stop head 31 can more accurately form an abutment fit with the limiting tooth 12. This not only increases the abutment force between the stop head 31 and the limiting tooth 12, that is, increases the limiting resistance applied by the stop head 31 to the outer side of the pot tooth 11 and reduces lateral movement, but also improves the reliability of the stop opening rod and the stop opening hole stop opening fit, effectively preventing forced opening of the lid under pressure and increasing safety. The difference between the first dimension L2 and the second dimension L3 is preferably 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, or 1.5 mm. The wall of the stop hole 32 is provided with a limiting surface 321 that engages with the stop rod 21 to limit the lateral movement of the stop plate 30 when it is engaged with the stop rod 21. The limiting surface 321 engages with the stop rod 21, limiting the lateral movement of the stop plate 30 when it is engaged with the stop rod 21, reducing the amount of swaying generated when the stop plate 30 is subjected to a forced opening force, and effectively improving the reliability of preventing forced opening.

[0044] It should be noted that "lateral" in this application refers to the horizontal direction or the direction within 15 degrees of the horizontal direction.

[0045] It should be noted that when the cooking appliance of this application is under pressure, the inner lid of the lid body 20 will float up and can move upward a certain distance relative to the pot body 10.

[0046] like Figures 5 to 8 As shown, the width of the side of the stop hole 32 near the second end of the stop plate 30 is smaller than the width of the side of the stop hole 32 away from the second end of the stop plate 30. This narrower side near the second end of the stop plate 30 allows for a more reliable limiting fit with the stop rod 21, reducing the swing of the stop rod 21 within the stop hole 32. This further restricts the lateral movement of the stop plate 30 when it engages with the stop rod 21, enhancing the stability against forced opening and effectively avoiding safety risks during the use of the cooking appliance. It should be noted that the stop hole 32 in this application is preferably non-circular.

[0047] It should be noted that the stop plate 30 is a long strip plate, and the "width" mentioned above refers to the distance between two opposite hole walls of the stop hole 32, which is equal to the width of the long strip plate.

[0048] To accommodate a first dimension L2 that is larger than the second dimension L3, the set distance L1 extending from the stop head 31 toward the vertical center line L4 of the pot body 10 is greater than or equal to 9.3 mm and less than or equal to 10.3 mm. Preferably, the set distance L1 extending from the stop head 31 toward the vertical center line L4 of the pot body 10 is 9.3 mm, 9.5 mm, 9.8 mm, 10 mm, or 10.3 mm.

[0049] like Figure 2 and Figures 5 to 8 As shown, the limiting surface 321 protrudes from the wall of the stop hole 32 along the axial direction of the stop hole 32. Thus, the provision of the limiting surface 321 enhances the limiting effect between the stop rod 21 and the stop plate 30, restricts the lateral movement of the stop plate 30 under the limiting engagement of the stop rod 21, reduces the sway of the stop plate 30 when subjected to a forced opening force, and improves the stability of the stop-opening engagement. This enhances the safety of the cooking appliance under pressure and effectively prevents forced opening. The gap between the wall of the stop hole 32 and the stop rod 21 is greater than or equal to 0.2 mm and less than or equal to 0.8 mm, preferably 0.2 mm, 0.5 mm, or 0.8 mm. Figure 2 and Figures 5 to 8 As shown, the limiting surface 321 is a limiting inclined surface. The limiting surface 321 with the limiting inclined surface can reduce the gap between the stop rod 21 and the stop plate 30 when they stop and open, reduce the amount of deflection of the stop plate 30, and ensure that the cover 20 is firmly locked under pressure.

[0050] In an embodiment not shown in the figure, the limiting surface 321 is a limiting curved surface.

[0051] like Figure 2 and Figures 5 to 8 As shown, the limiting surface 321 is located on the side adjacent to the end face of the second end of the stop hole 32 and the stop plate 30. The above structure directly restricts the lateral movement of the stop plate 30 by the limiting surface 321, reduces the sway of the stop plate 30, enhances the reliability of the stop-start engagement, and shortens the effective locking stroke of the stop head 31 when under force.

[0052] Specifically, the stop hole 32 is a square hole similar to a square, and the limiting surface 321 is located at the included angle of the square hole. There are two limiting surfaces 321, which are located at the two included angles adjacent to the end face of the square hole and the second end of the stop plate 30.

[0053] like Figure 2 and Figures 5 to 9As shown, there are multiple pot teeth 11, which are spaced apart circumferentially along the pot body 10. One of the pot teeth 11 is a limiting tooth 12. The limiting tooth 12 is locked into the lid 20, and the stop head 31 can abut against the outer surface of the limiting tooth 12. There is a first dimension L2 between the limiting tooth 12 and the vertical center line L4 of the pot body 10, and at least one of the remaining pot teeth 11 has a second dimension L3 between it and the vertical center line L4 of the pot body 10. The first dimension L2 is larger than the second dimension L3. The relationship between the first dimension L2 and the second dimension L3 allows the stop head 31 to be more firmly locked onto the limiting tooth 12, increasing the resistance when forcibly opening the lid, improving safety and preventing accidental opening.

[0054] Specifically, when the pot body 10 is in a pressureless state, the stop rod 21 is not inserted into the stop hole 32, and the stop head 31 can open or close the lid along with the lid 20. The stop head 31 will not interfere with the opening or closing process of the lid 20. When the cooking appliance is in a pressurized state, the stop rod 21 is inserted into the stop hole 32, and the stop head 31 abuts against the outer side of the limiting tooth 12. The stop head 31 prevents the lid 20 from opening, thus preventing the pot body 10 of the cooking appliance from being forcibly opened under pressure, thereby improving safety.

[0055] This application sets a set distance L1 extending from the stop start 31 toward the vertical center line L4 of the pot body 10, which is greater than or equal to 9.3 mm and less than or equal to 10.3 mm, and conducts the following test: Under 1.07 times the rated voltage, add water to a depth of about 25 mm in the pot body, install a pressure gauge on the lid, and disconnect the power supply after the pressure in the pot body reaches about 10 kPa. Allow the pressure in the pot body to cool naturally to 4 kPa, and apply a force of 200 N to the most unfavorable position of the lid or handle that can be gripped by hand using a push force gauge.

[0056] Under the action of a force of 200N, 270N, 280N, 290N, or 300N, because the stop head 31 extends a set distance L1 in the direction of the vertical center line L4 of the pot body 10 that is greater than or equal to 9.3mm and less than or equal to 10.3mm, the stop head 31 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.

[0057] like Figure 2 and Figures 5 to 10As shown, because the stop head 31 abuts against the limiting tooth 12, the entire lid 20 is pushed backward, causing a misalignment error in the front-to-back direction when the lid 20 and the pot body 10 are locked together. To solve this problem, the lid 20 includes a top plate 22 and a side plate 23 surrounding the edge of the top plate 22. The inner wall of the side plate 23 is provided with a protrusion 24 that can abut against the pot tooth 11. The protrusion 24 can reduce the misalignment error in the front-to-back direction when the lid 20 and the pot body 10 are locked together, so that the lid is more centered relative to the pot body, and the fit with the pot tooth 11 is tighter. This increases the resistance when forcibly opening the lid, making the use of the cooking utensil safer. The side plate 23 is provided with a through hole for the stop head 31 to pass through. The protrusion 24 abuts against the pot tooth 11 in the lateral direction.

[0058] It should be noted that the front and back directions refer to the side of the pot body 10 facing the user as the front and the side facing away from the user as the back.

[0059] The protrusion 24 is preferably a convex hull with a height of 0.5 mm and a diameter of less than or equal to 3 mm and greater than or equal to 5 mm. The diameter of the convex hull is preferably 3 mm, 4 mm, or 5 mm.

[0060] like Figure 2 and Figures 5 to 10 As shown, in order to further reduce the misalignment error in the front and rear directions when the lid 20 and the pot 10 are locked together, so that the lid is in a more central position relative to the pot, the protrusion 24 and the stop head 31 are located on both sides of the side plate 23 respectively.

[0061] like Figure 2 and Figures 5 to 10 As shown, the side plate 23 is provided with a lid tooth 25 that mates with the pot tooth 11, and a protrusion 24 is located above the lid tooth 25. The protrusion 24 works in conjunction with the lid tooth 25 to optimize the locking fit between the lid body 20 and the pot body 10, so that the lid body 20 can fit more smoothly with the pot tooth 11 when the lid is closed, and it is also convenient for the lid body to be smoothly centered relative to the pot body when the lid is closed.

[0062] like Figure 2 and Figures 5 to 10 As shown, the lid 20 also includes a top cover 26 located outside the top plate 22 and the side plate 23. The cooking appliance also includes an elastic member 40 disposed between the top cover 26 and the first end of the stop plate 30. The elastic member 40 applies an elastic force to the first end of the stop plate 30 in the direction of the stop head 31. The elastic member 40 ensures tight contact between the stop head 31 and the outer surface of the pot teeth 11, increases the limiting resistance of the stop head 31, and makes the stop plate 30 more securely locked under pressure, improving the reliability of the stop function. The elastic member 40 is preferably a spring.

[0063] like Figures 1 to 3 , Figure 11 and Figure 12 As shown, the pot body 10 includes a shell 13 and a heat insulation cover 14 disposed inside the shell 13, with pot teeth 11 disposed on the heat insulation cover 14. The design of the pot teeth 11 on the heat insulation cover 14 facilitates the machining of the pot teeth 11, effectively locks the lid 20, and also maintains the heat insulation performance inside the pot body 10.

[0064] It should be noted that in this application, "multiple" means two or more.

[0065] 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.

[0066] 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.

[0067] 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.

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.

[0068] 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.
