Lunch box using hot water to heat foods

Abstract

The invention discloses a lunch box using hot water to heat foods. The lunch box comprises a lunch box shell, a lunch box cover, a heat conduction inner container, a water storage cavity, a water filling port, a water outlet and a jacking mechanism. The jacking mechanism comprises a hard block and at least one foldable supporting member arranged at the bottom of the hard block, and the hard block moves up and down under the jacking action of the at least one foldable supporting member. The foods can be instantly heated by hot water through using the design of the water storage cavity, so hidden electricity safety troubles are avoided. The heat conduction inner container, the water filling port, the water storage cavity and the water outlet form a heat collection system, the foods are heated through heat conduction and hot steam, and hot water does not enter the inner container for containing foods, so the lunch box is convenient, and has a good heating effect. The normal heating function of foods also can be realized when the volume of hot water is small by using the jacking effect of the jacking mechanism and the elastic deformation of the bottom of the water storage cavity. The lunch box is used for heating foods.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a lunch box for heating food with hot water. Background technique [0002] The heat preservation lunch boxes, heat preservation pots and electric heating lunch boxes commonly used now realize the function of heat preservation or heating of food through the heat preservation characteristics of the material itself or by charging the heat generating material, but the above methods have the following disadvantages: [0003] (1) If the insulation is carried out through the insulation characteristics of the material itself, the insulation time is limited and cannot be reheated. At the same time, the requirements for the insulation characteristics of the material are high, and the production cost is high; [0004] (2) For thermal insulation or heating by charging heat-generating materials, its demand for power greatly limits the scope of use, and at the same time, the safety of electric...

Problems solved by technology

[0003] (1) If the insulation is carried out through the insulation characteristics of the material itself, the insulation time is limited and cannot be reheated. At the same time, the requirements for the insulation characteristics of the material are high, and the production cost is high;

[0004] (2) For thermal insulation or heating by charging heat-generating materials, its demand for power greatly limits the scope of use, and at the same time, the safety of electricity use has become a major obstacle to its popularization

[0005] A lunch box for heating food that can be conveniently heated at any time is lacking on the market, and its safety is high
