Novel composite cooker and manufacturing method thereof

Abstract

The invention provides a novel composite cooker which comprises a cooker body with the thickness of 1.5 mm-5.0 mm. The thickness of the cooker wall is successively and progressively decreased by the 2 mm-3 mm space from the upper portion of the plane of a cooker bottom to the edge of the cooker wall. The cooker body comprises an inner layer cooker body and an outer layer cooker body, the inner layer cooker body is made of one of iron, iron-base alloy, stainless steel, titanium and titanium alloy, the outer layer cooker body is made of aluminum alloy or pure aluminum or AZ31B magnesium alloy or magnesium alloy, and a magnetic conduction energy storage layer is pressed on the outer surface of the outer layer cooker body. The materials of the inner surface of the cooker is healthful and sanitary, the heat conduction performance of the outer surface of the cooker is good, the outer surface is light in material, the magnetic conduction energy storage layer is arranged on the outer portion of the cooker bottom, the heat collection effect of the cooker bottom is increased, cooking energy consumption is reduced, and the application range of the cooker is expanded. The invention further provides a manufacturing method of the novel composite cooker. The method is easy to operate, saves materials, reduces cost, and is convenient to implement and beneficial to industrialization of the novel composite cooker.

[0002] The 21st century is an era of high technology. Energy saving and environmental protection, health, safety and sanitation, convenience and convenience, and diversified life are the mainstream of today's era. However, our home kitchen life and cooking utensils are still in the background of the past. People use Cookware products are still made of old crafts and materials in the 1960s and 1970s. Modern technology proves that cookware products made of these materials and crafts waste energy to a certain extent, pollute the environment, and endanger human health. People have diversified and diverse needs in modern kitchen life, so it is imperative to develop cookware products that meet the needs of the new era

[0003] The current cookware products have some problems in the process of production and use. For example, composite stainless steel pot products, titanium and titanium alloy pots generally adopt a three-layer structure. First, the required materials must be rolled into plates for many times with large special equipment. , and then after cleaning and degreasing the above-mentioned plates, they are heated to the critical edge in a tunnel furnace, rolled and compounded by explosive welding or a rolling mill, punched to remove corners, and processed into discs required for pot forming, and then used for later use after diffusion annealing ; The product processed by this method has complicated technology, high material processing cost, serious energy waste, heavy product, and the general weight is 1.6-2.3Kg. It is difficult to use and operate for home cooking, and the practicability is poor; in addition, stainless steel pots, titanium and titanium alloys Pots generally adopt a three-layer or five-layer structure. Because cooking utensils have high requirements for the inner surface material of the pot that is in contact with food during actual use, safe, hygienic and healthy pot body materials are required, but the requirements for the outer surface of the pot are not high. High, and the traditional single-layer stainless steel double-bottom product, because there is no uniform heat conduction material on the bottom of the pot and the outer wall of the pot, the local heating of the pot body is uneven, resulting in local high temperature at the bottom of the pot, which is prone to oily smoke and food scorching. Although the material structure can solve the above problems, due to the influence of the composite processing technology, the area of ​​the inner and outer surface materials of the pot should be the same size, the thickness of the pot body should be equal, and the materials used are all high-cost metal materials. Waste of materials, high processing costs, high product prices, heavy pots, difficult to clean after sticking to dirt, pots are often discarded for this reason, resulting in loss and waste; and iron pots are easy to rust and uneven heat conduction, sticky Pots, cooking fumes, serious environmental pollution problems during the production process, heavy pots, etc. Although aluminum non-stick pans are light in weight and have good non-stick performance, because the non-stick coating is coated on softer aluminum Alloy matrix material, so the durability of the coating is not long, and the chemical coating and aluminum alloy precipitates are harmful to the human body and the environment, so the current cooker products can no longer meet the modern people's pursuit of nutrition, health, green, energy saving , environmental protection, convenient and practical, and low cost are the mainstream of the times
