Energy-saving lunch box

Abstract

The invention discloses an energy-saving lunch box. The energy-saving lunch box comprises an outer wall, an inner wall and a base, wherein the outer wall is a ring body; the inner wall is also a ring body and concentric with the outer wall; the outer wall of the base is cylindrical and in matching connection with the outer wall of the lunch box; and the inside of the base is a tapered circular hole and in matching connection with the inner wall of the lunch box. According to the energy-saving lunch box, a thermal cycle structure is formed to meet the requirement on heating inside and outside simultaneously.

Description

technical field [0001] The invention belongs to mechanical engineering, in particular to an energy-saving lunch box. Background technique [0002] At present, the existing electric steamer adopts a water-proof heating method, the electric heating plate heats the water in the pot, and the stainless steel rice bowl is heated from the outside to the inside by water vapor. [0003] Because its heating principle is to heat slowly from the outside to the inside, the outer wall of the lunch box is often very hot but the rice in the center of the lunch box is still cold, and the internal temperature can only be raised by heating for a long time. The rice on the outer wall of the lunch box will dry out. Contents of the invention [0004] Purpose of the invention: the purpose of the invention is to overcome the deficiencies of the prior art and provide an energy-saving lunch box capable of heating meals evenly. [0005] Technical solution: The energy-saving lunch box of the presen...
