Problems solved by technology

However, most of the existing cast iron enamel pots are integrally sintered enamel, otherwise defects are likely to exist at the end of the enamel glaze layer, and if the gap at the end is obvious, it will also affect the appearance. In addition, the effect of cooking solid food is not ideal due to the poor non-stickiness of the enamel. Therefore, cast iron enamel pots are mostly used as stew pots.
Although the current existing technology misses the cast iron enamel liner, the disclosed content only considers the functional aspects such as internal and external multi-layer angles, and does not involve specific connection issues. There is no real enamel glaze layer in the existing market. Therefore, how to use it as the inner tank of electric rice cooker, electric pressure cooker, etc. remains to be solved

Embodiment 1

[0028] Please refer to Figure 1 to Figure 3 , which is a relevant illustration of Embodiment 1 of an enamel inner container for cooking utensils according to the present invention.

[0029] refer to figure 1 As shown, an enamel inner container for cooking utensils includes a cast iron container body 10, the outer surface of the cast iron container body 10 is sintered with an enamel glaze layer 2, and the inner surface of the cast iron container body 10 is sprayed with a non-stick coating 3, Wherein the material of the non-stick coating 3 is preferably Teflon. By spraying the non-stick coating 3 on the inner surface of the cast iron tank body 10, the non-stick property of the inner tank during cooking is ensured. The enamel layer 2 is sintered on the outer surface of the cast iron tank 10 to improve the corrosion resistance of the cast iron tank 10 and the appearance of the inner tank.

[0030] Refer again figure 2 As shown, the mouth of the cast iron tank 10 has a radially...

Embodiment 2

[0048] see Figure 4 , which is a diagram of Embodiment 2 of an enamel liner for cooking utensils according to the present invention. The difference from Embodiment 1 is that the positions where the enamel layer 2 is connected to the non-stick coating 3 are different, as follows.

[0049] The corner between the outer end surface 11 of the flange 1 and the bottom surface 13 of the flange 1 is a second corner 15 , and the position where the enamel layer 2 and the non-stick coating 3 are connected is located at the second corner 15 .

[0050] In this embodiment, because the position where the enamel layer 2 and the non-stick coating 3 are connected is located at the second corner 15, the connection between the enamel layer 2 and the non-stick coating 3 faces downward, so even if the cooking time leaks The gas will cause the condensed water to slip from the flange 1, and will not penetrate into the cast iron tank 10 from the joint, so as to obtain good corrosion resistance.

Embodiment 3

[0060] see Figure 5 , which is a diagram of Embodiment 3 of an enamel liner for cooking utensils according to the present invention. It differs from the above-mentioned embodiments in that an aluminum layer 4 is sprayed between the cast iron tank 10 and the non-stick coating 3 .

[0061] After spraying the aluminum layer 4, the bonding strength of the non-stick coating 3 is increased. In addition, the heat transfer performance of aluminum is better than that of iron, which can quickly transfer the heat of cast iron, thereby improving the heating efficiency.

[0062] Wherein, the thickness of the aluminum layer 4 is between 50-150 microns, preferably 75 microns, 100 microns and 125 microns.

Abstract

The invention provides an enamel inner pot for cooking utensils, comprising a cast iron pot body, an enamel glaze layer is sintered on the outer surface of the cast iron pot body, and a non-stick coating is sprayed on the inner surface of the cast iron pot body. There is a radially outward flange at the gall opening of the flange, the enamel glaze layer and the non-stick coating both extend to the flange, and the outer end surfaces of the flange are respectively provided with the top surface and the bottom surface of the flange. A corner, where the junction of the enamel layer and the non-stick coating is located. The inner liner disclosed by the invention has a non-stick coating layer and an enamel glaze layer on the inner and outer surfaces respectively, and has the characteristics of less defects, beautiful appearance and good hand feeling.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an enamel inner container for cooking utensils. Background technique [0002] Because the iron liner has good heat storage performance, the cooking effect is better than that of other materials, so it is widely used in cooking utensils such as electric rice cookers and electric pressure cookers in the existing market. Among them, the optimal inner tank material is cast iron, but limited by the casting process of cast iron, it is difficult to make the surface of cast iron smooth, so the iron inner tank currently used in the market is formed by stretching thick iron plates to reduce costs . [0003] Most of the coatings for cast iron are enamel, and the rough surface of the enamel glaze layer and cast iron is just conducive to the combination of the two. Cast iron enamel pots are very popular among consumers because of their heavy feeling, beautiful appearance, strong ...
