Abstract

The invention discloses a heat-preserving lunchbox with an electric heating device and a phase change heat storage material, and relates to the field of chemistry. The invention achieves the purposes by providing the heat-preserving lunchbox which can heat food anytime and anywhere and continuously preserve heat for about one hour. In order to achieve the purposes, the invention heat-preserving lunchbox comprises three structural parts: a double-layer lunchbox main body, the electric heating device and the phase change heat storage material, wherein the double-layer lunchbox main body at least comprises two material layers, namely an inner layer and an outer layer; the material layers can be made of food-grade plastic or food-grade stainless steel; the electric heating device adopts an electric heating wire; the electric heating wire is powered by ordinary 220V commercial power, adopts a spiral shape as a whole and is uniformly wound onto an interlayer between the inner material layer and the outer material layer, and the periphery of the electric heating wire is filled with a large amount of the phase change heat storage material. The heat-preserving lunchbox has the advantages of capabilities of heating food anytime and anywhere and effectively preserving heat for a relatively long time.
