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] Currently, the highest pressure of conventional pressure cooking appliances on the market is 112 kPa. To shorten cooking time and improve the taste, the maximum pressure of the cooking appliance can be further increased.

[0003] However, due to the limitations of the existing product structure and strength, further increasing the pressure would pose a significant safety risk to users.

[0004] In related technologies, the maximum pressure of pressure cooking appliances is generally 112 kPa. To reduce cooking time and improve the taste of food, it is advisable to set the maximum pressure of the pressure cooker higher.

[0005] However, for existing products, further increasing the pressure would significantly increase the safety risks for users during use. Utility Model Content

[0006] The main purpose of this utility model is to provide a cooking appliance to solve the problem that increasing pressure in related technologies would greatly increase the safety risks for users during use.

[0007] To achieve the above objectives, this utility model provides a cooking utensil, comprising: a pot body with a first snap fastener; a lid assembly disposed on the pot body, the lid assembly including a locking member and a pressure-bearing lid, the pressure-bearing lid sealingly fitting with the pot body, the locking member having a second snap fastener that engages with the first snap fastener, the locking member being movably disposed and capable of locking or unlocking the pot body; and an exhaust structure including an exhaust pipe disposed on the pressure-bearing lid and a pressure-limiting valve disposed on the exhaust pipe; wherein, the thickness T1 of the locking member satisfies: 1.8mm≤T1≤2.5mm; and the thickness T2 of the pressure-bearing lid satisfies: 1.5mm≤T2≤2mm.

[0008] By applying the technical solution of this utility model, in order to improve the structural strength of the cooking appliance, the thickness of the relatively weak parts of the pressure-bearing structure inside the cooking appliance (generally the pressure-bearing cover and locking member in related technologies) is adjusted. Specifically, the pot body with the first snap tooth and the locking member with the second snap tooth are interlocked and locked together, and the pressure-bearing capacity during the cooking process is achieved through the pot body, the locking member, and the pressure-bearing cover. In the technical solution of this application, the thickness of both the locking member and the pressure-bearing cover is increased. The thickness T1 of the locking member satisfies: 1.8mm≤T1≤2.5mm; the thickness T2 of the pressure-bearing cover satisfies: 1.5mm≤T2≤2mm. By increasing the thickness of the locking member and the pressure-bearing cover, the structural strength of the cooking appliance is improved, which can further increase the maximum cooking pressure. The technical solution of this application effectively solves the problem that further increasing the pressure in related technologies would greatly increase the safety risks for users during use.

[0009] Furthermore, the pot body features a double-layered inner pot. The outer layer of the double-layered inner pot is made of stainless steel, while the inner layer is made of aluminum. The thickness T3 of the double-layered inner pot satisfies the condition: 4mm ≤ T3 ≤ 4.5mm. This double-layered inner pot is relatively inexpensive, and it's easy to create graduations on the inner layer for cooking rice or porridge. The thickness T3, satisfying 4mm ≤ T3 ≤ 4.5mm, enhances the structural strength of the double-layered inner pot, thereby further reducing safety risks for users.

[0010] Furthermore, the outer layer of the double-walled inner pot has a thickness greater than or equal to 0.6 mm. This dimensional range balances structural strength and manufacturing cost.

[0011] Furthermore, the pot body has a three-layer inner pot. The inner and outer layers of the three-layer inner pot are made of stainless steel, while the middle layer is made of aluminum. The thickness T4 of the three-layer inner pot satisfies the following condition: 2mm ≤ T4 ≤ 3.2mm. The inner layer of the aforementioned three-layer inner pot is in direct contact with the food, and the material of the inner layer ensures that it will not react with the food during cooking, guaranteeing food safety and making it convenient for making soup. The thickness T4 of the aforementioned three-layer inner pot satisfies the condition: 2mm ≤ T4 ≤ 3.2mm, which improves the structural strength of the three-layer inner pot and further reduces the safety risks for users during use.

[0012] Furthermore, the sum of the thicknesses of the outer and inner layers of the three-layer inner pot is greater than or equal to 1.5 mm. This dimensional range balances structural strength and manufacturing cost.

[0013] Furthermore, when the locking component locks the pot body, the first and second locking teeth are stacked, and the overlap dimension D of the first and second locking teeth in the radial direction of the pot body satisfies: 2.5mm ≤ D ≤ 4mm. This overlap dimension effectively ensures the engagement between the locking component and the pot body, avoiding the safety risks associated with disengagement.

[0014] Furthermore, the locking element is made of 304 stainless steel, 430 stainless steel, or 316 stainless steel; and / or, the pressure cap is made of 304 stainless steel, 430 stainless steel, or 316 stainless steel. Using these materials for the locking element improves structural strength. Since the pressure cap comes into direct contact with food, its material ensures that it will not react with the food during cooking, thus guaranteeing food safety.

[0015] Furthermore, the weight M of the pressure relief valve satisfies: 78g ≤ M ≤ 102g, and / or the included angle α of the exhaust pipe outlet satisfies: 89° ≤ α ≤ 108°. The weight of the pressure relief valve meets the required cooking pressure, and the included angle of the exhaust pipe outlet is matched to the weight of the pressure relief valve, ensuring that the pressure relief valve remains lightweight while meeting the requirements, thereby reducing manufacturing costs.

[0016] Furthermore, the cooking appliance also includes an outer shell, within which the pot body is housed. The outer shell enhances the aesthetic appeal and facilitates the installation of other components within it.

[0017] Furthermore, the cover assembly also includes a faceplate, which is positioned above the locking member and the pressure-bearing cover. The faceplate has an operating element that drives the locking member to rotate. This faceplate improves the aesthetic appearance and facilitates the installation of other components within it. The operating element facilitates operation of the locking member. Attached Figure Description

Detailed Implementation

[0035] 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.

[0036] 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.

[0037] 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.

[0038] like Figures 1 to 6 As shown, the cooking appliance of this embodiment includes: a pot body 10, a lid assembly 20, and a venting structure 30. The pot body 10 is provided with a first latch 111; the lid assembly 20 is disposed on the pot body 10 and includes a locking member 21 and a pressure-bearing cover 22. The pressure-bearing cover 22 is sealed to the pot body 10. The locking member 21 is provided with a second latch 211 that engages with the first latch 111. The locking member 21 is movably disposed and can lock or unlock the pot body 10; the venting structure 30 includes a vent pipe 31 disposed on the pressure-bearing cover 22 and a pressure-limiting valve 32 disposed on the vent pipe 31; wherein the thickness T1 of the locking member 21 satisfies: 1.8mm ≤ T1 ≤ 2.5mm; the thickness T2 of the pressure-bearing cover 22 satisfies: 1.5mm ≤ T2 ≤ 2mm.

[0039] In this embodiment, to improve the structural strength of the cooking appliance, the thickness of the weaker parts of the pressure-bearing structure (generally the pressure-bearing cover and locking member in related technologies) is adjusted. Specifically, the pot body 10 with the first snap tooth 111 and the locking member 21 with the second snap tooth 211 are interlocked and locked together, and the pressure-bearing capacity during cooking is achieved by the pot body 10, the locking member 21, and the pressure-bearing cover 22. In this embodiment, the thickness of both the locking member 21 and the pressure-bearing cover 22 is increased. The thickness T1 of the locking member 21 satisfies: 1.8mm ≤ T1 ≤ 2.5mm; the thickness T2 of the pressure-bearing cover 22 satisfies: 1.5mm ≤ T2 ≤ 2mm. By increasing the thickness of the locking member 21 and the pressure-bearing cover 22, the structural strength of the cooking appliance is improved, which can further increase the maximum cooking pressure. This embodiment effectively solves the problem in related technologies that further increasing the pressure would greatly increase the safety risks for users during use.

[0040] The thickness T1 of the locking component 21 and the thickness T2 of the pressure-bearing cover 22 not only improve structural strength and reduce safety risks to users, but also balance user experience and manufacturing costs. Theoretically, the thicker the component, the better the structural strength; however, excessive thickness significantly increases product weight, degrades user experience, and increases manufacturing costs.

[0041] In a preferred embodiment, the thickness T1 of the locking member 21 can be 1.8mm, 1.9mm, 2mm, 2.1mm, 2.3mm, or 2.5mm. The locking member 21 can be a locking ring, and the second locking tooth 211 is a flange located at the bottom of the locking ring. The locking ring is rotatably configured, is a stamped part, and has a consistent thickness at all positions. Alternatively, as a feasible embodiment, the locking member can also be a caliper, which is movably configured along the radial direction of the pot body 10.

[0042] The thickness T2 of the pressure cover 22 can be 1.5mm, 1.6mm, 1.7mm, 1.8mm or 2mm. The pressure cover 22 is a stamped part, and the thickness of the pressure cover 22 is consistent at all locations.

[0043] The inner pot design can be implemented in two ways: a double-layered inner pot or a triple-layered inner pot. It can also be a single-layered inner pot, or have more than three layers. Generally, a non-stick coating is provided on the inner surface of the aforementioned double-layered or triple-layered inner pot. It should be noted that the aforementioned double-layered or triple-layered inner pot specifically refers to an inner pot base material that is double-layered or triple-layered. Based on the double-layered or triple-layered design, a coating, plating, or cladding layer can also be provided on the inner or outer surface of the inner pot base material. The number of layers in the inner pot does not include the aforementioned functional layers such as coatings, plating, or cladding layers. In this embodiment, the pot body 10 needs to withstand pressure, so increasing the thickness improves structural strength and thus enhances the pressure-bearing effect. The first snap tooth 111 of the pot body 10 is formed by flanging at the opening of the pot body 10.

[0044] like Figure 7 and Figure 8 As shown, when the pot body 10 is a double-layered inner pot, the outer layer of the double-layered inner pot is made of stainless steel, and the inner layer is made of aluminum. The thickness T3 of the double-layered inner pot satisfies the condition: 4mm ≤ T3 ≤ 4.5mm. This double-layered inner pot has a lower cost and allows for easy creation of graduation lines on the inner layer, facilitating cooking rice or porridge. The thickness T3 of the double-layered inner pot satisfies the condition: 4mm ≤ T3 ≤ 4.5mm, which improves the structural strength of the double-layered inner pot and further reduces safety risks for users. The thickness T3 of the double-layered inner pot can be 4mm, 4.2mm, 4.3mm, or 4.5mm. Preferably, the outer layer of the double-layered inner pot is made of 430 stainless steel, and the inner layer is made of AL3003.

[0045] The outer layer of the double-walled inner pot has a thickness greater than or equal to 0.6 mm. This size range balances structural strength and manufacturing cost.

[0046] like Figure 9 and Figure 10 As shown, when the pot body 10 is a three-layer inner pot, the inner and outer layers of the three-layer inner pot are made of stainless steel, and the middle layer is made of aluminum. The thickness T4 of the three-layer inner pot satisfies: 2mm ≤ T4 ≤ 3.2mm. The inner layer of the aforementioned three-layer inner pot is in direct contact with the food, and the material of the inner layer ensures that it will not react with the food during cooking, guaranteeing food safety and facilitating soup making. The thickness T4 of the aforementioned three-layer inner pot satisfies: 2mm ≤ T4 ≤ 3.2mm, which improves the structural strength of the three-layer inner pot, thereby further reducing the safety risks for users during use. The thickness T4 of the three-layer inner pot can be 2mm, 2.2mm, 2.6mm, or 3.2mm. Preferably, the outer layer of the three-layer inner pot is made of 430 stainless steel, the inner layer is made of 304 or 316 stainless steel, and the middle layer is made of AL3003.

[0047] The combined thickness of the outer and inner layers of the three-layer inner pot is greater than or equal to 1.5 mm. This dimensional range balances structural strength and manufacturing cost.

[0048] like Figure 5 As shown, when the locking member 21 locks the pot body 10, the first locking tooth 111 and the second locking tooth 211 are stacked. The overlap dimension D of the first locking tooth 111 and the second locking tooth 211 in the radial direction of the pot body 10 satisfies: 2.5mm ≤ D ≤ 4mm. The above-mentioned overlap dimension D can effectively ensure the engagement between the locking member 21 and the pot body 10, avoiding the safety risk caused by disengagement. It should be noted that the above-mentioned overlap dimension D refers to the horizontal distance between the outer edge of the first locking tooth 111 and the inner edge of the second locking tooth 211 in the radial direction of the pot body 10. The above-mentioned overlap dimension D can be 2.5mm, 3mm, 3.2mm, 3.5mm, or 4mm. The larger the overlap dimension D, the better the engagement effect, but it will lead to manufacturing difficulties and higher costs. The above-mentioned overlap dimension D reduces the manufacturing difficulty and cost while improving the engagement effect.

[0049] The locking component 21 is made of 304 stainless steel, 430 stainless steel, or 316 stainless steel. Using these materials for the locking component improves structural strength.

[0050] The pressure-bearing cover 22 is made of 304 stainless steel, 430 stainless steel, or 316 stainless steel. Since the pressure-bearing cover 22 will come into direct contact with the food, its material ensures that it will not react with the food during cooking, thus guaranteeing food safety.

[0051] like Figure 6 As shown, in this embodiment, the weight M of the pressure relief valve 32 satisfies: 78g ≤ M ≤ 102g. The weight of the pressure relief valve 32 is sufficient to meet the required cooking pressure. If the pressure relief valve 32 is too light, it is easy for it to tip over during venting. The weight M of the pressure relief valve 32 can be 78g, 84g, 90g, 96g, or 102g.

[0052] The included angle α of the exhaust pipe 31's outlet satisfies: 89° ≤ α ≤ 108°. It should be noted that the included angle of the exhaust pipe 31's outlet refers to the angle between the sidewall of the exhaust pipe 31's outlet and a predetermined vertical plane, which passes through the axis of the exhaust pipe 31. The included angle α of the exhaust pipe 31's outlet can be 89°, 92°, 95°, 98.5°, 102°, or 108°.

[0053] The outlet angle of the exhaust pipe 31 is designed to match the weight of the pressure relief valve 32, ensuring that the pressure relief valve 32 remains lightweight while meeting the required cooking pressure, thereby reducing manufacturing costs. Under the same pressure conditions, a larger outlet angle of the exhaust pipe 31 allows for a lighter pressure relief valve 32. However, a larger outlet angle also increases manufacturing difficulty. Therefore, the design must comprehensively consider both the outlet angle of the exhaust pipe 31 and the weight of the pressure relief valve 32 to achieve a balance between cost and ease of manufacturing.

[0054] like Figure 1 and Figure 2 As shown, the pot body 10 also includes an outer shell 40, and the pot body 10 is disposed inside the outer shell 40. The outer shell 40 can improve the appearance and at the same time facilitate the installation of other components inside the outer shell 40.

[0055] like Figure 1 and Figure 2 As shown, the cover assembly also includes a faceplate 24, which is positioned above the locking member 21 and the pressure-bearing cover 22. The faceplate 24 has an operating member 23 for driving the locking member 21 to rotate. The faceplate 24 improves the aesthetic appearance and facilitates the installation of other components within it. The operating member 23 facilitates operation of the locking member 21. The operating member 23 is a rotating handle, but in other embodiments, it can also be a carrying handle.

[0056] In this embodiment, a sealing ring 25 is also provided on the pressure cover 22, which can seal with the pot body 10.

[0057] The cooking appliance in this application is an electric pressure cooker.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.
