Abstract
Description
Technical Field
[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a pot body structure and a cooking utensil having the same. Background Technology
[0002] Currently, cooking utensils include a pot body, a pan body, and a lid. The pot body has a heating structure. When the heating structure is powered on, it can transfer heat to the pan body, thereby heating the food.
[0003] In related technologies, when the heating structure heats the pot body, the pot body has a large heating area, which leads to concentrated heating. This makes it difficult for the food inside the pot to physically tumble and achieve uniform heating. Utility Model Content
[0004] The main objective of this invention is to provide a pot body structure and a cooking appliance having the same structure, in order to solve the problem of concentrated heat distribution in the pot body in related technologies.
[0005] To achieve the above objectives, according to one aspect of the present invention, a pot body structure is provided, comprising: a pot body; and a plurality of recessed structures arranged at intervals in the lower part of the pot body, wherein the recessed structures protrude into the interior of the pot body, and a protruding structure is formed between two adjacent recessed structures, and the distance between the bottom surface of the recessed structure and the bottom surface of the protruding structure is between 5 mm and 15 mm.
[0006] By employing the technical solution of this utility model, multiple recessed structures are arranged at intervals on the lower part of the pot body, with each recessed structure protruding inwards. A protruding structure is formed between two adjacent recessed structures; specifically, the distance between the bottom surface of the recessed structure and the bottom surface of the protruding structure is between 5mm and 15mm. Through this arrangement, when the pot body is heated, the bottom surfaces of the recessed and protruding structures can be heated differently. Furthermore, the 5mm to 15mm distance between the bottom surfaces of the recessed and protruding structures ensures that each structure is heated individually, thus preventing concentrated heat distribution within the pot body and improving the physical tumbling effect of the food inside. Therefore, the technical solution of this application effectively solves the problem of concentrated heat distribution in pot bodies in related technologies.
[0007] Furthermore, multiple recessed structures are spaced apart along the circumference of the pot body. This arrangement ensures uniform heating and avoids heat concentration.
[0008] Furthermore, multiple recessed structures are located on the bottom surface of the pot body, or the first end of the recessed structure is located on the bottom surface of the pot body, and the second end of the recessed structure extends to the side wall of the pot body. This arrangement ensures effective heating and can accommodate different heating structures.
[0009] Furthermore, the top surface of the recessed structure includes a first transition surface, a second transition surface, and a connecting surface. The connecting surface is located between the first and second transition surfaces and is parallel to the outer surface of the protruding structure located in the same circumferential direction. The aforementioned first and second transition surfaces can transition with the pot body, thereby avoiding corners on the pot body.
[0010] Furthermore, the pot body structure also includes a central section, located at the center of the bottom surface of the pot body, adjacent to the first end of the recessed structure. This central section can cooperate with the temperature measuring element, thereby improving the accuracy of temperature measurement.
[0011] Furthermore, the width of the recessed structure gradually increases from the center of the pot body to its outer periphery. This design ensures the heating area.
[0012] Furthermore, the side walls of the pot body can be vertical or curved. These different pot body shapes cater to various usage needs.
[0013] According to another aspect of this utility model, a cooking utensil is provided, including a pot body structure, wherein the pot body structure is as described above. The aforementioned pot body structure can avoid concentrated heat, thereby improving the tumbling effect of food within the pot body. Therefore, the cooking utensil with the aforementioned pot body structure also possesses the aforementioned advantages.
[0014] Furthermore, the cooking appliance also includes a pot body structure and a heating structure disposed within the pot body structure, with the pot body structure detachably mounted above the heating structure. The aforementioned heating structure enables heating of the pot body structure, and through the protruding and recessed structures, it avoids concentrated heat distribution.
[0015] Furthermore, the distance between the top surface of the recessed structure of the pot body and the heating structure is between 14mm and 25mm, or the distance between the top surface of the recessed structure of the pot body and the heating structure is between 2mm and 6mm. These distance settings ensure that when the recessed structure is heated, the protruding structure cannot be heated, or vice versa. Attached Figure Description

[0025] like Figure 1 and Figure 2 As shown, in this embodiment, the pot body structure includes a pot body 10 and a plurality of recessed structures 20. The plurality of recessed structures 20 are arranged at intervals in the lower part of the pot body 10. The recessed structures 20 protrude into the interior of the pot body 10, and a protruding structure 30 is formed between two adjacent recessed structures 20. The distance between the bottom surface of the recessed structure 20 and the bottom surface of the protruding structure 30 is between 5 mm and 15 mm.
[0026] In this embodiment, multiple recessed structures 20 are spaced apart on the lower part of the pot body 10, protruding into the interior of the pot body 10. A protruding structure 30 is formed between two adjacent recessed structures 20. Specifically, the distance between the bottom surface of the recessed structure 20 and the bottom surface of the protruding structure 30 is between 5mm and 15mm. Through this arrangement, when the pot body is heated, the bottom surface of the recessed structure 20 or the bottom surface of the protruding structure 30 can be heated differently. Furthermore, since the distance between the bottom surface of the recessed structure 20 and the bottom surface of the protruding structure 30 is between 5mm and 15mm, it ensures that either the protruding structure 30 or the recessed structure 20 is heated individually, thus avoiding concentrated heat distribution within the pot body and improving the physical tumbling effect of the food inside the pot. Therefore, this embodiment effectively solves the problem of concentrated heat distribution in the pot body in related technologies.
[0027] It should be noted that in this embodiment, the depths of the multiple recessed structures 20 are the same.
[0028] The “lower part of the pot body 10” mentioned above refers to the part above the maximum diameter of the pot body, and the part below the maximum diameter.
[0029] Of course, in other embodiments, some of the recessed structures 20 have the same recessed depth, while the rest have different recessed depths, or the recessed structures 20 have different recessed depths.
[0030] Specifically, the pot structure of this embodiment is used in an electrically heated cooking appliance.
[0031] When the heating structure 60 is energized, it directly heats the protruding structure 30. Only when the protruding structure 30 is heated can the temperature be transferred to the recessed structure 20. Since the pot body 10 is a metal part, the temperature transfer is relatively slow. Therefore, the temperature of the protruding structure 30 is directly transferred to the food inside the pot body 10, and then transferred to the recessed structure 20 through the food. During this temperature transfer process, bubbles are generated at the contact surface between the food and the pot body. When heated to a certain temperature, the bubbles move upward continuously, allowing the food to move from the area of the protruding structure 30 to the recessed structure 20. The temperature difference between the recessed structure 20 and the food is small, and almost no bubbles are generated. Therefore, after the temperature of the area of the protruding structure 30 rises, it naturally moves to the area of the recessed structure 20 where the temperature is lower, thus achieving the heating and tumbling phenomenon.
[0032] In an embodiment not shown in the figure, the pot structure can be used for open flame heating.
[0033] like Figure 1 and Figure 2 As shown, in this embodiment, multiple recessed structures 20 are spaced apart along the circumference of the pot body 10. This arrangement ensures uniform heating and avoids concentrated heat distribution.
[0034] like Figure 1 and Figure 2 As shown, in this embodiment, multiple recessed structures 20 are located on the bottom surface of the pot body 10. This arrangement ensures effective heating and can accommodate different heating structures.
[0035] In an embodiment not shown in the figure, the first end of the recessed structure 20 is located on the bottom surface of the pot body 10, and the second end of the recessed structure 20 extends to the side wall of the pot body 10. When the heating structure extends to the side wall of the pot body 10, the above arrangement can ensure the heating effect.
[0036] like Figure 1 and Figure 2As shown, in this embodiment, the top surface of the recessed structure 20 includes a first transition surface 21, a second transition surface 22, and a connecting surface 23. The connecting surface 23 is located between the first transition surface 21 and the second transition surface 22, and is parallel to the outer surface of the protruding structure 30 located in the same circumferential direction. The aforementioned first transition surface 21 and second transition surface 22 can transition with the pot body 10, thereby avoiding corners on the pot body 10. At the same time, the setting of the connecting surface 23 can ensure the distance between it and the heating structure, thereby ensuring the heating effect.
[0037] like Figure 1 and Figure 2 As shown, in this embodiment, the pot body structure also includes a central portion 40, which is located at the center of the bottom surface of the pot body 10 and is adjacent to the first end of the recessed structure 20. The aforementioned central portion 40 can cooperate with the temperature measuring element, thereby improving the accuracy of temperature measurement.
[0038] Specifically, the central part 40 is platform-shaped.
[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the width of the recessed structure 20 gradually increases from the center of the pot body 10 to its outer periphery. This arrangement ensures sufficient heating area.
[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the sidewall of the pot body 10 is arc-shaped. Of course, in other embodiments, the sidewall of the pot body 10 is vertical.
[0041] It should be noted that when the side wall of the pot body 10 is arc-shaped, the "bottom surface of the pot body 10" mentioned above refers to the part of the pot body 10 located below the top section of the heating structure.
[0042] When the side wall of the pot body 10 is vertical, the "bottom surface of the pot body 10" mentioned above refers to the part of the pot body 10 facing the heating structure.
[0043] According to another aspect of this application, a cooking utensil is provided, such as Figure 3 As shown, the cooking appliance of this embodiment includes a pot body structure, which is the pot body structure described above. The pot body structure described above can avoid heat concentration, thereby improving the tumbling effect of food inside the pot body 10. Therefore, the cooking appliance with the pot body structure described above also has the aforementioned advantages.
[0044] like Figure 3As shown, in this embodiment, the cooking appliance also includes a pot body structure 50 and a heating structure 60 disposed within the pot body structure 50. The pot body structure is detachably mounted on top of the heating structure 60. The heating structure 60 can heat the pot body structure, and under the action of the protruding structure 30 and the recessed structure 20, it can avoid heat concentration.
[0045] Specifically, the heating structure 60 is an IH heating coil.
[0046] like Figure 3 As shown, in this embodiment, the distance between the top surface of the recessed structure 20 of the pot body structure and the heating structure 60 is between 14mm and 25mm. This distance setting ensures that when the protruding structure 30 is heated, the recessed structure 20 cannot be heated, thereby preventing concentrated heat distribution on the pot body.
[0047] Of course, the distance between the top surface of the recessed structure 20 of the pot body structure and the heating structure 60 can also be set between 2mm and 6mm, so that when the recessed structure 20 is heated, the protruding structure 30 cannot be heated.
[0048] It should be noted that the magnetic distance between the protruding structure 30 and the heating structure 60 is the ideal heating distance, which is usually 8mm to 12mm. The recessed structure 20 protrudes or recedes by a certain distance on the basis of the protruding structure 30, so that the heating of the recessed structure 20 by the heating structure 60 is drastically reduced.
[0049] In one case, the distance between the recessed structure 20 and the heating structure 60 is 14mm to 25mm. In this case, the heating structure 60 can heat the protruding structure 30. However, the distance between the recessed structure 20 and the heating structure 60 is too large, making it difficult to achieve heating.
[0050] In another scenario, the distance between the protruding structure 30 and the heating structure 60 is 2–6 mm; two or more recessed structures 20 can be provided on the protruding structure 30 and evenly distributed circumferentially on the pot body 10; each recessed structure 20 extends radially; in this way, the heating structure 60 heats the recessed structure 20, reducing the direct heating of the protruding structure 30 by the heating structure 60, and heat convection is formed by the interpenetration of multiple recessed structures 20 and protruding structures 30, achieving the effect of food tumbling inside the pot; this solution only requires local molding on the inner pot, and has advantages such as simple process, easy production and low cost.
[0051] 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.
[0052] 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.
[0053] 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.
[0054] 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.
