Abstract
Description
Technical Field
[0001] The present application relates to the technical field of small household appliances, and in particular to a cooking utensil. Background Art
[0002] The bottom of the electric steamer currently on the market is usually flat. Since the water in the electric steamer usually needs to be boiled for a long time, the long-term heating can easily cause the bottom of the pot to deform, resulting in a loose fit between the pot and the heating plate, uneven heating of the pot, and affected heat transfer efficiency. Utility Model Content
[0003] Based on this, it is necessary to provide a cooking utensil that can reduce the deformation of the bottom of the pot body.
[0004] A cooking utensil comprises a shell, a heating component arranged in the shell, and a pot body arranged on the heating component, wherein the pot body and the shell are detachable, and the pot body comprises a main body, a composite bottom sheet and a bottom wrapping sheet, wherein the bottom wall of the main body is provided with a boss protruding downward, the composite bottom sheet is arranged below the boss, and the bottom wrapping sheet covers the composite bottom sheet and is fixedly connected to the bottom wall of the main body.
[0005] The present application strengthens the structural strength of the bottom wall of the main body by arranging a boss on the bottom wall of the main body, and further strengthens the structural strength of the bottom wall of the main body by arranging a composite bottom sheet under the boss, and arranging a bottom sheet covering the composite bottom sheet, so that the bottom of the pot body is more easily arranged into a shape that fits the top surface of the heating component, and the main body is not easily deformed, thereby avoiding the problem of uneven heating caused by deformation of the main body and ensuring the heat transfer efficiency.
[0006] In one embodiment, the boss is covered on the inner side of the bottom sheet, the composite bottom sheet is in contact with or fixedly connected to the bottom wall of the boss, and the composite bottom sheet is in contact with or fixedly connected to the inner bottom wall of the bottom sheet.
[0007] In this way, the connection strength between the bottom wrapping sheet, the composite bottom sheet and the main body is higher, and it is not easy for the composite bottom sheet or the bottom wrapping sheet to fall off and cause damage to the pot body. In addition, the fixed connection or fit between the three can achieve efficient heat transfer.
[0008] In one embodiment, the boss is formed by partially deforming the bottom wall of the body so as to bulge downward.
[0009] In this way, the structure is simple, and the bottom wall of the body and the boss are an integral structure with high structural strength.
[0010] In one embodiment, the bottom wall of the boss protrudes upward to form a first upward convex arc portion, the complex film is an arc-shaped sheet body adapted to the first upward convex arc portion, and the bottom wall of the package film protrudes upward to form a second upward convex arc portion, and the second upward convex arc portion is adapted to the arc-shaped sheet body.
[0011] In this way, by providing the first upward convex arc portion, the boss is not easily deformed when heated, thereby reducing the probability of deformation of the main body. By providing the arc-shaped sheet body and the second upward convex arc portion, the curvature of the first upward convex arc portion can be guaranteed, so that deformation problems are less likely to occur. At the same time, the heat transfer efficiency will not be affected by the existence of gaps between the composite film and the boss, and between the wrapping film and the composite film, thereby ensuring the heat transfer effect of the wrapping film, the composite film and the boss.
[0012] In one embodiment, the heating assembly includes a heating plate, the pot body is placed on the top surface of the heating plate, the top surface of the heating plate protrudes upward to form an upward convex arc surface, and the upward convex arc surface is matched with the second upward convex arc portion.
[0013] In this way, the heating plate and the bottom sheet are tightly fitted, ensuring the rapid transfer of heat, thereby improving the heat transfer efficiency, and the upper convex arc surface is adapted to the second upper convex arc portion, that is, the contact surface between the heating plate and the bottom sheet is an arc surface. Compared with a flat surface, the arc surface has a larger contact area and a higher heat transfer efficiency.
[0014] In one embodiment, the composite film is spaced a certain distance from the edge of the bottom wall of the main body.
[0015] In this way, materials can be saved while ensuring the structural strength of the bottom wall of the main body.
[0016] In one embodiment, the height H of the boss relative to the bottom wall of the body is 1 mm to 10 mm.
[0017] In this way, the reinforcement effect of the boss on the bottom wall structure of the main body is ensured without affecting the overall height of the main body.
[0018] In one embodiment, the thickness D1 of the duplex film is 1 mm to 5 mm.
[0019] In this way, the structural strength of the boss is enhanced and the consumables of the duplication film can be saved, thereby effectively controlling the cost.
[0020] In one embodiment, the thickness D2 of the bottom sheet is 0.3 mm to 1.0 mm.
[0021] In this way, the structural strength of the boss is enhanced and the consumables of the film can be saved, thereby effectively controlling the cost.
[0022] In one embodiment, the cooking utensil is an electric steamer, an electric boiling pot, an electric hot pot, a food processor, an electric rice cooker or an electric frying pan.
[0023] In this way, the pot body is not easily deformed when heated for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0035] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediate medium. Moreover, a first feature being “above”, “above” or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below” or “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0036] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0037] See also Figures 1 to 6The present application provides a cooking utensil, comprising a housing 500, a heating assembly 400 disposed in the housing 500, and a pot body 100 disposed on the heating assembly 400. The pot body 100 and the housing 500 are detachable. The pot body 100 comprises: a body 10, a composite bottom sheet 20 and a bottom cover sheet 30, the bottom wall of the body 10 is provided with a boss 11 protruding downward, the composite bottom sheet 20 is disposed below the boss 11, and the bottom cover sheet 30 covers the composite bottom sheet 20 and is fixedly connected to the bottom wall of the body 10. The present application strengthens the structural strength of the bottom wall of the main body 10 by setting a boss 11 on the bottom wall of the main body 10, and further strengthens the structural strength of the bottom wall of the main body 10 by setting a composite bottom film 20 under the boss 11, and setting a bottom wrapping film 30 that wraps the composite bottom film 20, so that the bottom of the pot body 100 is more easily set to a shape that fits the top surface of the heating component 400, and the bottom of the pot body 100 is not easy to deform, thereby avoiding the problem of uneven heating caused by deformation of the pot body 100 and ensuring heat transfer efficiency.
[0038] It is understandable that the bottom sheet 30 is fixedly connected to the bottom wall of the main body 10 . The bottom sheet 30 can be fixedly connected to the boss 11 or to the bottom wall of the main body 10 outside the boss 11 .
[0039] Furthermore, the boss 11 is covered on the inner side of the bottom cover 30, the composite bottom sheet 20 is fitted or fixedly connected to the bottom wall of the boss 11, and the composite bottom sheet 20 is fitted or fixedly connected to the inner bottom wall of the bottom cover 30. In this way, the connection strength between the bottom cover 30, the composite bottom sheet 20, and the main body 10 is higher, and it is not easy for the composite bottom sheet 20 to fall off or the bottom cover 30 to fall off and cause damage to the pot body 100. In addition, the fixed connection or fit between the three can achieve efficient heat transfer.
[0040] In one embodiment, the composite bottom sheet 20 can be fixedly connected to the boss 11 of the body 10 by a high-temperature brazing process, and the bottom cover sheet 30 can be fixedly connected to the composite bottom sheet 20 and the bottom wall of the body 10 by a high-temperature sintering process. During processing, the boss 11 can be processed first, and then the composite bottom sheet 20 is welded under the boss 11, and finally the bottom cover sheet 30 is covered on the bottom of the body 10 by a high-temperature sintering process.
[0041] In this embodiment, the body 10 and the bottom cover 30 are both made of stainless steel, and the composite bottom film 20 is made of aluminum alloy. Both aluminum alloy and stainless steel have the characteristics of fast heat transfer. When heated, the bottom cover 30 is heated by the heating plate 40, so that the body 10 can be heated quickly. In addition, the durability of stainless steel is better than that of aluminum alloy, and the price of aluminum alloy is cheap. In this embodiment, the body 10 and the bottom cover 30 located on the outside are made of stainless steel, and the composite bottom film 20 located on the inside is made of aluminum alloy, which not only ensures the durability of the product, but also reduces the cost.
[0042] Furthermore, the boss 11 is formed by partially deforming the bottom wall of the body 10 to bulge downward, so that the structure is simple, and the bottom wall of the body 10 and the boss 11 are an integral structure with high structural strength. In this embodiment, the boss 11 can be formed by the body 10 through a stamping process.
[0043] The duplex film 20 is spaced a certain distance from the edge of the bottom wall of the main body 10, that is, the duplex film 20 does not cover the entire bottom wall of the main body 10. In this embodiment, the duplex film 20 only covers the bottom wall of the main body 10 where the boss 11 is set. In this way, material is saved while ensuring the structural strength of the bottom wall of the main body 10.
[0044] In this embodiment, the bottom wall of the body 10 is square, and the boss 11 is circular. However, it is not limited thereto, in other embodiments, the bottom wall of the body may also be circular or other shapes, and the boss may also be square or other shapes.
[0045] See also Figure 3 , Figure 5 and Figure 6 Further, the bottom wall of the boss 11 bulges upward to form a first convex arc-shaped portion 111, the composite bottom sheet 20 is an arc-shaped sheet body that matches the first convex arc-shaped portion 111, and the bottom wall of the bottom package sheet 30 bulges upward to form a second convex arc-shaped portion 31, and the second convex arc-shaped portion 31 matches the arc-shaped sheet body. In this way, by setting the first convex arc-shaped portion 111, the boss 11 is not easily deformed when heated, which reduces the probability of deformation of the main body 10. By setting the arc-shaped sheet body and the second convex arc-shaped portion 31, the curvature of the first convex arc-shaped portion 111 can be guaranteed, so that deformation problems are not likely to occur. At the same time, the gap between the composite bottom sheet 20 and the boss 11, and between the bottom package sheet 30 and the composite bottom sheet 20 will not affect the heat transfer efficiency, thereby ensuring the heat transfer effect of the bottom package sheet 30, the composite bottom sheet 20 and the boss 11.
[0046] See also Figure 1 and Figure 3 Furthermore, the heating component 400 includes a heating plate 40, and the pot body 100 is placed on the top surface of the heating plate 40. The top surface of the heating plate 40 bulges upward to form an upper convex arc surface 41, and the upper convex arc surface 41 is matched with the second upper convex arc portion 31. In this way, the heating plate 40 is tightly fitted with the bottom sheet 30, ensuring the rapid transfer of heat, thereby improving the heat transfer efficiency. Moreover, the upper convex arc surface 41 is matched with the second upper convex arc portion 31, that is, the contact surface between the heating plate 40 and the bottom sheet 30 is an arc surface. Compared with a flat surface, the arc surface has a larger contact area and a higher heat transfer efficiency.
[0047] See also Figure 6In one embodiment, the height H of the boss 11 relative to the bottom wall of the main body 10 is 1mm to 10mm. If H is too small, the setting of the boss 11 will not have a significant effect on strengthening the structural strength of the bottom wall of the main body 10; if H is too large, the overall height of the main body 10 will be relatively high. In this embodiment, H is 1mm to 10mm, which is a moderate size, which not only ensures the strengthening effect of the boss 11 on the structural strength of the bottom wall of the main body 10, but also does not affect the overall height of the main body 10. Specifically, H can be 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or any other value within the range of 1mm to 10mm.
[0048] See also Figure 6 In one embodiment, the thickness D1 of the duplex film 20 is 1 mm to 5 mm. If the thickness D1 of the duplex film 20 is too small, the structural strength of the boss 11 cannot be effectively enhanced; if the thickness D1 of the duplex film 20 is too large, more consumables are required and the cost is high. In this embodiment, D1 is 1 mm to 5 mm, which is a moderate size. It not only ensures the enhancement effect on the structural strength of the boss 11, but also saves consumables of the duplex film 20, thereby effectively controlling the cost. Specifically, D1 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, or any other value within the range of 1 mm to 5 mm.
[0049] See also Figure 6 In one embodiment, the thickness D2 of the bottom film 30 is 0.3mm to 1.0mm. If the thickness D2 of the bottom film 30 is too small, the structural strength of the body 10 at the boss 11 cannot be effectively strengthened; if the thickness D2 of the bottom film 30 is too large, more consumables are required and the cost is high. In this embodiment, D2 is 1mm to 5mm, which is a moderate size. It not only ensures the strengthening effect on the structural strength of the body 10, but also saves the consumables of the bottom film 30, thereby effectively controlling the cost. Specifically, D2 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, or any other value within the range of 0.3mm to 1.0mm.
[0050] like Figure 1 and Figure 2As shown, in this embodiment, the cooking utensil is an electric steamer, and the pot body 100 is not easy to deform even when heated for a long time. The electric steamer also includes a steamer 600 and a pot cover 700 arranged above the pot body 100. However, it is not limited to this. In other embodiments, the cooking utensil can also be an electric cooker, an electric hot pot, an electric rice cooker, a cooking pot or an electric frying pan. The cooking utensil ensures that the pot body 100 is not easy to deform by setting the above structure. For different cooking utensils, the pot body 100 can have different names. For example, for an electric steamer, the pot body 100 can be called a water tank, and steam is generated by heating the water in the water tank when in use; for an electric rice cooker, the pot body 100 can be called an inner pot; for an electric hot pot and a cooking pot, the pot body 100 can be called a shabu-shabu.
[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0052] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
