The utility model proposes a pot body, which is used for containing food, and can be used in conjunction with pots such as electric rice cooker, electric pressure cooker, electric stew pot, etc. or can be directly placed on an electromagnetic oven or an open flame for heating food.

With reference to Fig. 1, Fig. 1 has shown the specific structure in an embodiment of the pot body of the present utility model. In the embodiment of the utility model, the pot body includes an aluminum alloy pot bottom 11 and an aluminum alloy pot wall 12 , and the pot bottom 11 and the pot wall 12 are preferably integrally formed by stretching. In order to reduce stress concentration, the pot bottom 11 and the pot wall 12 can be transitionally connected by an arc surface 13, and the radius of the arc surface 13 is preferably 10 mm to 15 mm. The bottom of the pot 11 is in direct contact with the heating plate of the pot, and is a direct heating surface, and transmits heat to the pot wall 12 and the food to heat the food. The outer surface of the pan bottom 11 is coated with an aluminum layer 20 and a magnetically permeable metal layer 30 in turn, and the aluminum layer 20 and the magnetically permeable metal layer 30 respectively extend to the outer surface of the pot wall 12 to partially or completely cover the pot wall 12 . Since the outer surface of the aluminum layer 20 is covered with a layer of magnetically conductive metal layer 30, the pot body can be heated in a magnetic field. In one embodiment, the magnetically permeable metal layer 30 is preferably made of stainless steel, which has high magnetic permeability and better magnetic permeability. Of course, the magnetically conductive metal layer 30 may also be made of other materials, such as iron.

In the pot body of the present invention, since the outer surface of the pot bottom 11 is covered with a layer of aluminum layer 20, the pot body has a thicker bottom, and because the thermal conductivity of aluminum is greater than that of aluminum alloy, the bottom of the pot The heat can be transferred away in time, and quickly transferred to the pot wall 12, so that the pot body is heated evenly everywhere, so as to evenly heat the food in the pot and prevent the bottom food from zooming or the top food from being difficult to be cooked. At the same time, compared with the existing method of thickening the thickness of the pot bottom 11 and the pot wall 12 at the same time, the pot body of the utility model adopts the method of covering the aluminum layer 20, which can ensure uniform heating while ensuring the thickness of the pot bottom. 11 and the thickness of the pot wall 12 are relatively thin, thereby reducing the processing difficulty of the bottom of the pot 11 and the pot wall 12, and can reduce the consumption of materials and the weight of the pot body. In addition, the adhesion between aluminum alloy and aluminum is better, so the connection between the aluminum layer 20 and the pot bottom 11 and the pot wall 12 is more reliable.

In the above embodiments, the aluminum layer 20 and the magnetically permeable metal layer 30 are welded on the bottom 11 and the wall 12 of the pot in sequence. The welding method has the effect of simple and reliable connection. In other embodiments, the aluminum layer 20 and the magnetically permeable metal layer 30 may also be connected to the pot bottom 11 and the pot wall 12 by hot pressing.

In order to reduce the trapped air between the bottom of the pot 11 and the aluminum layer 20, in this embodiment, the thickness of the aluminum layer 20 gradually decreases from the center of the pot body along the radial direction of the pot body, so that the aluminum The layer 20 extends all around and vents the gas between the pan bottom 11 and the aluminum layer 20 . Further, the center of the outer surface of the bottom of the pot 11 is sunken toward the inside of the pot to form a recessed area. In this way, the outer surface of the bottom of the pot 11 forms a shape that is high in the middle and low on the four sides, so that the aluminum layer 20 can be pressed and formed with the bottom of the pot 11. , the gas between the aluminum layer 20 and the bottom of the pan 11 runs from the center to all around as far as possible. Moreover, the pot bottom 11 with a convex center can form a circular contact with the heating plate of the pot, which is conducive to the stable placement of the pot body; at the same time, for the inside of the pot body, it is conducive to the convection of air bubbles.

In the present invention, if the thickness of the pot body is too thin, the heat transfer uniformity of the pot body will be affected; and if the thickness of the pot body is too thick, the pot body will be too heavy and the material cost will increase. Therefore, in the present invention, the thickness of the pot bottom 11 and the pot wall 12 is 1.2-4 mm, the maximum thickness of the aluminum layer 20 is 2-8 mm, and the thickness of the magnetically conductive metal layer 30 is 0.3-1.5 mm. In a specific embodiment, preferably, the thickness of the pot bottom 11 and the pot wall 12 is 3 mm, the maximum thickness of the aluminum layer 20 , that is, the thickness at the center is 6 mm, and the thickness of the magnetically permeable metal layer 30 is 1 mm. In this way, the thickness of the pot wall 12 and the bottom of the pot body can both have an appropriate thickness, so as to realize uniform heat transfer of the pot body.

Since the top opening of the pot wall 12 is generally arranged in the form of a flanging, if the thickness of this place is relatively thin, it will easily cause the flanging to break. Therefore, in this embodiment, the thickness of the top end of the pot wall 12 is greater than the thickness of the bottom end of the pot wall 12 . Preferably, the thickness of the top opening of the pot wall 2 is 1.5-4.5 mm. In a specific embodiment, the thickness of the opening at the top of the bottom of the pot 2 may be 4 mm. In this way, the strength of the opening can be ensured.

The utility model also proposes a pot, which includes a pot body. The specific structure of the pot body refers to the above-mentioned embodiments. Since this pot adopts all the technical solutions of all the above-mentioned embodiments, it has at least the advantages of the above-mentioned embodiments. All beneficial effects brought by the technical solution will not be repeated here. Wherein, the pot body can be used alone. For example, the pot body can be directly heated on an open flame. When the pot body is directly heated, the pot preferably can also include a pot cover matched with the pot body. Or, the pot body can be used in conjunction with pots such as electric rice cooker or electric pressure cooker, and when the pot body is used in conjunction with the pot, a heating device is provided in the pot, such as a heating plate, and the heating plate and the outer pot body The bottoms are in direct contact to transfer heat to the inner pot, which heats the food inside. Because the cooker adopts the above-mentioned pot body, the heating plate can fully contact with the pot body, and by using the aluminum layer 20 as a heat-conducting medium, the uniform transfer of heat is realized, and the heat loss is small. Therefore, the pot of the utility model The heating efficiency is high and the heating effect is good, which is conducive to the uniform heating of food, and can save heating time and cost.

The above are only preferred embodiments of the present utility model, and are not therefore limiting the patent scope of the present utility model. Under the inventive concept of the present utility model, the equivalent structural transformations made by utilizing the specification of the utility model and the contents of the accompanying drawings, or directly/ Indirect application in other relevant technical fields is included in the patent protection scope of the present utility model.
