Food tray with heat retention function

Abstract

The utility model relates to technical field and disclose a food tray with heat -preserving function, including inner layer, the outside of inner layer is provided with heat -preserving layer, and the space of 1 centimeter is left between inner layer and heat -preserving layer, and the space left between inner layer and heat -preserving layer is filled with water body, the outer wall of heat -preserving layer is provided with outer layer, and the electric heating seat is installed in the outer layer bottom center, and the heating end surface distribution of electric heating seat is in the center of the water bath space left between inner layer and heat -preserving layer. The food tray through integrated design embeds the water bath heat -preserving system in the tray structure, realizes the self -heating heat -preserving function without external heating equipment. The design not only has promoted user experience, has simplified the operation step, and through water bath heat transfer mode has guaranteed the even constant temperature of food, has effectively prolonged food heat -preserving time, has improved food quality.
