▎ 摘　　要

NOVELTY - The device has a box body (1) whose front wall upper part is provided with an insulating door (2). A left lower corner of the front wall of the box body is provided with a waste gas inlet (11). A lower right corner of a back wall of the box body is provided with a waste gas outlet. A center of a top wall of the box body is provided with a through hole. A placing bowl (3) is placed in the through hole. A distilled water collecting pipe is passed through a hole of a center of a food plate, and extends to a lower part of the placing bowl, where diameter of the distilled water collecting pipe is less than that of the through hole. A lower end of an outer wall of the distilled water collecting pipe is provided with a horizontal water outlet pipe (10) that extends from a right side wall of the box body, where the distilled water collecting pipe is made of food grade stainless steel material. The water outlet pipe is provided with a valve. USE - Food reheating device using gas heat source used during self-driving travel, long-distance transportation, and emergency and disaster relief. ADVANTAGE - The food reheating device is energy-saving and environment-friendly, and has high energy efficiency utilization rate, fast heating speed, full functional element, and large food quantity, and solves the problem of inconvenient food supply for personnel in scenarios such as self-driving travel, long-distance transportation, and emergency and disaster relief. The surface of the inner wall of the box body and the graphene film coated on the upper surface of baffle plate make the radiating faster and more uniform, thus improving the heat conduction efficiency. The box body base adopts the pipe coil structure, increases the heat exchange, the heating process adopts the superheated steam internal circulation, the meal heating area is large, the heat distribution is uniform, and the heating speed is fast. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a food reheating device using gas heat source. 1Box body 2Insulating door 3Placing bowl 8Thermometer 9Pressure valve 10Water outlet pipe 11Waste gas inlet
