Problems solved by technology

With the continuous alternation of cold and heat when the pot is used, the separation of the metal layer at the bottom of the pot will soon occur, and the phenomenon of bulge at the bottom of the pot will appear, which seriously reduces the thermal conductivity of the bottom of the pot. In order to alleviate this problem, existing manufacturers often use Thicken the thickness of the composite plate at the bottom of the pot to increase the heat capacity of the pot and reduce the temperature difference, and the thickened plate makes the weight of the pot too heavy. Generally, the weight of an ordinary stainless steel wok with a diameter of 32cm can reach 1kg-1.5 kg, if the dishes in the pot are added, its weight will reach more than 2kg, which makes it very inconvenient for housewives to use

specific Embodiment 1

[0015] Specific embodiment 1, in conjunction with figure 1 , 2 and image 3 Specifically explaining this embodiment, the high thermal conductivity stainless steel pot includes a pot body, a pot handle, and a pot cover if necessary. The pot body is a double-layer stainless steel sandwich structure. These two layers of stainless steel plates are molded to form the upper pot body 5 and the lower pot body 2 respectively, and then the upper and lower pot bodies are welded together along the edge of the pot by welding. At the same time, the vacuum pumping pipeline 7 is reserved on the welding of the lower pot body 2 for leak detection, and the double-layer stainless steel interlayer structure is guaranteed to be in a sealed state, and the oil and dust are cleaned and polished for later use.

[0016] For the preparation of the molten salt heat conductor, the solid aluminum chloride+sodium chloride+potassium chloride molten salt product with a melting point of about 100°C is selecte...

specific Embodiment 2

[0019] Specific embodiment 2, in conjunction with figure 2 , image 3 Specifically explaining this embodiment, the high thermal conductivity stainless steel pot includes a pot body, a pot handle, and a pot cover if necessary. The pot body is a double-layer stainless steel sandwich structure. The two layers of stainless steel plates are molded to form the upper pot body 5 and the lower pot body 2 respectively, and then the upper pot body 5 and the handle 3 are connected by riveting, and then the Clean oil and dust, polish and dry before use. Squeeze a barbed wire 8 slightly smaller than the lower pot body with a mold, remove rust and clean oil stains, dust, polish and dry it for later use.

[0020] Select the solid sodium nitrate+potassium nitrate+sodium nitrite molten salt product with a melting point of about 100°C, and melt it for use. Assemble the upper pot body 5 and the lower pot body 2, put the barbed wire 8 into the interlayer, weld the edge part of the lower pot bo...

specific Embodiment 3

[0023] Specific embodiment 3, electric rice cooker uses high thermal conductivity stainless steel liner pot body. The pot body is a double-layer stainless steel sandwich structure. These two layers of stainless steel plates are molded to form the upper pot body 5 and the lower pot body 2 respectively, and then the oil and dust are cleaned and polished for use.

[0024] For the preparation of the molten salt heat conductor 6, solid aluminum chloride+sodium chloride+potassium chloride molten salt products with a melting point of about 100° C. are selected, and after melting, 40-mesh aluminum powder with a weight ratio of 2% is added, and The 40-mesh iron powder with 10% by weight is used as the sacrificial anode 1 and the ferromagnetic material 8 to become the molten salt heat conductor 6 . Pour the melted molten salt heat conductor 6 into a mold similar to the shape and volume of the interlayer gap of the pot body. The volume of the molten salt heat conductor 6 is about 50% of ...

Abstract

The invention provides a novel high thermal conductive stainless steel cooker manufacturing method. The defects that an existing stainless steel cooker is poor in thermal conductivity, cooker stickingoccurs in the cooking process, the cooker bottom is prone to swelling and layering, and a cooker body is heavy are avoided. The cooker body is of a sandwich structure, a sandwich is filled with a molten salt heat conductor which is a mixture of molten salt and active metal materials, the active metals comprise aluminum, magnesium, zinc, iron, nickel and the like, or an alloy of the active metalsis used as a sacrificial anode, corrosion of the molten salt to the stainless steel cooker can be prevented or relieved, ferro magnetic materials such as iron and nickel are added in the molten salt,and by adding the metals, the stainless steel cooker is suitable for an induction cooker. An overheating warning module is arranged in a cooker handle of the cooker, when accidents occur and the cooker is burnt dry, a temperature-sensing element in the overheating warning module is connected with a circuit automatically, a warning ring is issued, and people are reminded of turning of heat in time.

Description

technical field [0001] The invention relates to the technical field of molten salt heat transfer. Molten salt has a relatively low melting temperature, is suitable for a wide range of heat transfer temperatures, and is not easy to decompose. It is a new material that replaces heat transfer oil in recent years. The present invention uses the characteristics of molten salt for the manufacture of stainless steel pots. The pot body is a pot with a sandwich structure, and the molten salt heat conductor with a low melting point is filled into the interlayer of the pot body. During the process of heating the pot body, The molten salt heat conductor is liquefied to realize liquid convection heat transfer, and the heat is evenly distributed, avoiding the problem of local hot spots in the stainless steel pot, so that the dishes are heated evenly, and it is not easy to stick to the pot, and the pot body can withstand high and low temperature thermal shock. Background technique [0002]...
