Abstract
Description
Technical Field
[0001] This utility model relates to the field of small household appliance technology, specifically to a heat preservation cover structure, a pot body assembly, and a cooking appliance. Background Technology
[0002] Electric pressure cookers are a common household appliance, widely recognized for their cooking efficiency and convenience. An electric pressure cooker includes a heat preservation cover, an inner pot, a heating element, and a lid. The heating element heats the inner pot and is supported by a support structure at the bottom of the heat preservation cover.
[0003] In related technologies, the bottom of the heat insulation cover is provided with a horizontal flange. The horizontal flange is used to support the support structure. When the support structure is under stress, all the force will be transferred to the horizontal flange, which can easily lead to deformation and damage of the heat insulation cover. Utility Model Content
[0004] The main purpose of this utility model is to provide a heat preservation cover structure, a pot body assembly, and a cooking appliance to solve the problem that heat preservation covers in related technologies are prone to deformation.
[0005] To achieve the above objectives, according to one aspect of the present invention, a heat insulation cover structure is provided, comprising: an annular sidewall; a first flange disposed at the bottom of the annular sidewall and extending into the interior of the annular sidewall, the first flange having a first support section for bearing pressure; and a second flange connected to the first flange and extending in a vertical direction, the second flange having a second support section for bearing pressure.
[0006] Applying the technical solution of this utility model, the first flange is set at the bottom of the annular sidewall and extends into the interior of the annular sidewall, while the second flange is connected to the first flange and extends vertically. During operation, the first and second support sections act as two pressure-bearing areas, preventing stress concentration at any point and thus avoiding deformation of the insulation cover structure. Specifically, both the first and second flanges can bear force, ensuring that the force on the insulation cover structure is the resultant force of the forces on the first and second flanges, with the direction of the resultant force between the directions of the forces on the first and second flanges. This reduces the possibility of damage to the first and second flanges. Furthermore, since the second flange is connected to the first flange, the overall strength of the insulation cover structure is improved. Therefore, the technical solution of this application effectively solves the problem of easy deformation of insulation covers in related technologies.
[0007] Furthermore, the ratio of the lateral dimension of the first flange to the vertical dimension of the second flange is between 1 and 6. This dimensional setting ensures a reasonable balance between the dimensions of the first and second flanges, providing sufficient space within the insulation cover structure to accommodate the inner pot or the coil structure for mounting cooking utensils. Excessive length of the first flange would negatively impact the deformation resistance of the first support section. Additionally, the dimensions of the second flange also support the first flange, ensuring both have sufficient deformation resistance and effectively improving the overall structural strength.
[0008] Furthermore, the second flange extends downwards. The above-mentioned arrangement makes the processing of the insulation cover structure easier, and it also causes the force on the insulation cover structure to tilt downwards and towards the outside of the insulation cover, thus preventing the force from being transmitted to other structures.
[0009] Furthermore, the included angle between the first flange and the second flange is between 60° and 120°. This angle setting makes the processing of the first flange and the second flange easier and provides better structural strength.
[0010] Furthermore, the first flange is a first annular plate, and / or the second flange is a second annular plate. The first and second annular plates have simple structures that are easy to process, and the continuous annular structure can enhance their strength and improve their pressure-bearing capacity.
[0011] According to another aspect of this utility model, a pot body assembly is provided, comprising: a heat-insulating cover structure; a supporting structure disposed within the heat-insulating cover structure, the supporting structure being abutting against both a first flange and a second flange, and acting on the first and second supporting sections; and an inner pot disposed within the heat-insulating cover, the inner pot having an inclined arc-shaped wall, the arc-shaped wall being supportingly engaged with the supporting structure; wherein the heat-insulating cover structure is the aforementioned heat-insulating cover structure. The aforementioned heat-insulating cover structure has a first flange and a second flange, thereby improving the overall structural strength of the heat-insulating cover structure; therefore, the pot body assembly having the aforementioned heat-insulating cover structure also possesses the aforementioned advantages.
[0012] Furthermore, the support structure is equipped with a support part that abuts against the inner pot. The support part makes the position of the inner pot more stable.
[0013] Furthermore, there are multiple support components, which are spaced apart circumferentially along the support structure. This arrangement effectively reduces the weight of the support structure.
[0014] Furthermore, the cooker assembly also includes an IH heating structure, which is located below the insulation cover structure. The ratio of the maximum diameter of the inner pot to the outer diameter of the IH heating structure is between 0.8 and 0.94. The IH heating structure can heat the inner pot, thereby enabling the cooking function. Simultaneously, the aforementioned ratio setting allows the IH heating structure to heat a larger area of the inner pot, thus improving heating efficiency and shortening heating time.
[0015] According to another aspect of this utility model, a cooking appliance is provided, including a pot body assembly, which is the pot body assembly described above. The heat preservation cover structure of the pot body assembly described above has good strength and is not easily damaged; therefore, the cooking appliance having the pot body assembly described above also has the aforementioned advantages.

[0022] 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.
[0023] 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.
[0024] 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.
[0025] like Figure 1 and Figure 2 As shown, in this embodiment, the heat insulation cover structure includes: an annular sidewall 10, a first flange 20, and a second flange 30. The first flange 20 is disposed at the bottom of the annular sidewall 10 and extends into the annular sidewall 10, and the first flange 20 has a first support section 21 for bearing pressure. The second flange 30 is connected to the first flange 20 and extends in the vertical direction, and the second flange 30 has a second support section 31 for bearing pressure.
[0026] Applying the technical solution of this utility model, the first flange 20 is disposed at the bottom of the annular sidewall 10 and extends into the annular sidewall 10, and the second flange 30 is connected to the first flange 20 and extends in the vertical direction. When the insulation cover structure is in operation, the first support section 21 and the second support section 31 serve as two pressure-bearing areas, which can prevent stress concentration at a certain point in the insulation cover structure from causing failure. Both the first flange 20 and the second flange 30 can bear force, so that the force on the insulation cover structure is the resultant force of the force on the first flange 20 and the force on the second flange 30, and the direction of the resultant force is between the directions of the forces on the first flange 20 and the second flange 30. This reduces the possibility of damage to the first flange 20 and the second flange 30. Furthermore, since the second flange 30 is connected to the first flange 20, the overall strength of the insulation cover structure can be improved. Therefore, the technical solution of this application effectively solves the problem of easy deformation of insulation covers in related technologies.
[0027] Specifically, the direction of the force on the first support segment 21 is always vertically downward. The direction of the force on the second support segment 31 changes with the position of the support and the position of the force.
[0028] It should be noted that the "lateral direction" mentioned above is not limited to the horizontal direction, but also includes directions that are at a certain angle to the horizontal direction. For example, directions with an angle of ±30° to the horizontal direction can be understood as lateral directions. Similarly, the "vertical direction" mentioned above is not limited to the vertical direction, but also includes directions that are at a certain angle to the vertical direction. For example, directions with an angle of ±30° to the vertical direction can be understood as vertical directions.
[0029] The first support segment can be a part of the structure of the first flange, with the remaining parts of the first flange not bearing pressure. Alternatively, the entire structure of the first flange can form the first support segment. Correspondingly, the second support segment can be a part of the structure of the second flange, with the remaining parts of the second flange not bearing pressure. Alternatively, the entire structure of the second flange can form the second support segment.
[0030] In this embodiment, the second flange 30 is connected to the inner edge of the first flange 20.
[0031] In other embodiments, the second flange 30 is connected to the middle of the first flange 20 or at other locations.
[0032] like Figure 1 and Figure 2As shown, in this embodiment, the ratio of the lateral dimension of the first flange 20 to the vertical dimension of the second flange 30 is between 1 and 6. This dimensional setting ensures that the dimensions of the first flange 20 and the second flange 30 are reasonably set, providing sufficient space for the insulation cover structure to accommodate the inner pot or the coil structure for installing cooking utensils. Furthermore, an excessively long first flange 20 would affect the deformation resistance of the first support section 21. In addition, the dimensional setting of the second flange 30 also supports the first flange 20, ensuring that both have sufficient deformation resistance, thereby effectively improving the overall structural strength.
[0033] Specifically, in this embodiment, the ratio of the lateral dimension of the first flange 20 to the vertical dimension of the second flange 30 is 3.
[0034] The horizontal dimension of the first flange 20 is between 8mm and 35mm, and the vertical dimension of the second flange 30 is between 3mm and 10mm.
[0035] Specifically, in this embodiment, the first flange 20 extends horizontally. The aforementioned "lateral dimension of the first flange 20" refers to the dimension of the first flange 20 along its extension direction, that is, the dimension of the first flange 20 along the radial direction of the insulation cover structure. Keeping the lateral dimension of the first flange 20 within the aforementioned range allows it to extend relatively close to the curved wall, avoiding an excessively large lateral dimension of the support structure 40, which would increase its cost. Furthermore, it ensures the support strength of the first flange 20, preventing it from easily deforming under stress. Preferably, the lateral dimension of the first flange 20 can be 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, 32mm, 34mm, or 35mm.
[0036] It should be noted that the "vertical dimension of the second flange 30" mentioned above refers to the dimension of the second flange 30 in its extension direction, that is, the dimension of the second flange 30 along the height direction of the insulation cover structure. Keeping the vertical dimension of the second flange 30 within the aforementioned range facilitates the processing of the second flange 30 and ensures its supporting strength, making it less prone to deformation under stress. Preferably, the vertical dimension of the second flange 30 can be 4mm, 6mm, 8mm, or 10mm.
[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the second flange 30 extends downward. The above-described arrangement makes the processing of the insulation cover structure easier, and also ensures that the force on the insulation cover structure is tilted downward and towards the outside of the insulation cover structure, thus preventing the force from being transmitted to other structures.
[0038] This prevents the resultant force from being directed towards the coil, thus preventing damage to the coil.
[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the included angle between the first flange 20 and the second flange 30 is between 60° and 120°. This angle setting makes the processing of the first flange 20 and the second flange 30 easier and provides better structural strength.
[0040] Specifically, in this embodiment, the included angle between the first flange 20 and the second flange 30 is 90°.
[0041] Of course, the included angle mentioned above can also be 65°, 70°, 75°, 80°, 85°, 95°, 100°, 105°, 110°, 115°, 120° or other angles.
[0042] like Figure 1 and Figure 2 As shown, in this embodiment, the first flange 20 is a first annular plate, and the second flange 30 is a second annular plate. The first and second annular plates have simple structures that are easy to process, and the continuous annular structure can enhance their strength and improve their pressure-bearing capacity.
[0043] According to a second aspect of this application, a cooker body assembly is provided, such as... Figure 3 As shown, the pot body assembly of this embodiment includes: a heat-insulating cover structure, a support structure 40, and an inner pot 50. The support structure 40 is disposed within the heat-insulating cover structure, and abuts against both the first flange 20 and the second flange 30, thereby acting on the first support section 21 and the second support section 31. The inner pot 50 is disposed within the heat-insulating cover, and the inner pot 50 has an inclined arc-shaped wall, which supports and cooperates with the support structure 40. The heat-insulating cover structure is the aforementioned heat-insulating cover structure. The aforementioned heat-insulating cover structure has the first flange 20 and the second flange 30, thereby improving the overall structural strength of the heat-insulating cover structure. Therefore, the pot body assembly with the aforementioned heat-insulating cover structure also possesses the aforementioned advantages.
[0044] like Figure 3 As shown, in this embodiment, a support portion 41 is provided on the support structure 40, and the support portion 41 abuts against the inner pot 50. The provision of the support portion 41 makes the position of the inner pot more stable.
[0045] like Figure 3 As shown, in this embodiment, there are multiple support portions 41, which are spaced apart circumferentially along the support structure 40. This arrangement effectively reduces the weight of the support structure 40.
[0046] Specifically, in this embodiment, there are six support portions 41. The six support portions 41 are arranged at equal intervals along the circumference of the support structure 40.
[0047] It should be noted that, to ensure the heat resistance of the support structure 40, PPS (polyphenylene sulfide) material can be used to make the support structure 40. Compared with the solution of using the first flange 20 and the second flange 30 to directly support the inner pot 50, the setting of the support structure 40 can reduce the wear of the arc-shaped wall of the inner pot 50 (both the heat preservation cover structure and the inner pot 50 are metal structures, and the wear of the inner pot 50 is greater when it rotates relative to the heat preservation cover structure), and at the same time, it can prevent the heat of the inner pot 50 from being directly transferred to the heat preservation cover structure, which would cause the heat preservation cover structure to become too hot.
[0048] like Figure 3 As shown, in this embodiment, the cooker assembly also includes an IH heating structure 60, which is disposed below the insulation cover structure. The ratio of the maximum diameter of the inner pot 50 to the outer diameter of the IH heating structure 60 is between 0.8 and 0.94. The IH heating structure 60 can heat the inner pot 50, thereby realizing the cooking function. Simultaneously, the aforementioned ratio setting allows the IH heating structure 60 to heat a larger area of the inner pot 50, thereby improving heating efficiency and shortening heating time.
[0049] Specifically, in this embodiment, both the IH heating structure 60 and the inner pot 50 have circular cross-sections. The "diameter of the IH heating structure 60" refers to the effective heating diameter of the IH heating structure 60, and the "maximum diameter of the inner pot 50" refers to the radius of the outer wall at the maximum diameter position of the inner pot 50. By ensuring that the ratio between the maximum diameter of the inner pot 50 and the diameter of the IH heating structure 60 is within the aforementioned range, the number of turns of the coil in the IH heating structure 60 is increased. This ensures that the bottom of the inner pot 50 has sufficient heating area, guaranteeing heating efficiency. Furthermore, it allows for sufficient vertical and horizontal space between the IH heating structure 60 and the inner pot 50 at their maximum lateral dimensions to accommodate the first support section 21, the second support section 31, and the support structure 40. This allows the first support section 21, the second support section 31, and the support structure 40 to fit into the arc-shaped wall of the inner pot 50, thereby reducing the height of the insulation cover structure. Preferably, the ratio can be 0.8, 0.85, 0.9, or 0.94.
[0050] In a preferred embodiment, the diameter of the maximum weft circle of the inner pot 50 is 223 mm, and the effective diameter of the IH heating structure 60 (that is, the diameter of the outer edge of the IH heating structure 60) is greater than or equal to 180 mm and less than or equal to 210 mm.
[0051] According to a third aspect of this application, a cooking appliance is provided. The cooking appliance of this embodiment includes a pot body assembly, which is the pot body assembly described above. The heat insulation cover structure of the pot body assembly described above has good strength and is not easily damaged; therefore, the cooking appliance having the pot body assembly described above also has the aforementioned advantages.
[0052] In the description of this utility model, it should be understood that "multiple" means a quantity of two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely 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 limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.
[0053] 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.
[0054] 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.
[0055] 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.
