Food heat-preservation box

Abstract

The invention particularly relates to a food heat-preservation box, which comprises a box body, a first heating device, a second heating device and a controller are arranged in the box body; the controller comprises a temperature sensor, an A / D conversion module, a microprocessor, a first relay and a second relay. The temperature sensor is connected with the microprocessor through the A / D conversion module, the microprocessor controls starting and stopping of the first heating device through the first relay, and the microprocessor controls starting and stopping of the second heating device through the second relay. Through the arrangement of the first heating device, the second heating device and the controller, when the temperature difference is not large, heat preservation operation canbe achieved by starting the first heating device, and when the temperature difference is large, heat preservation operation can be achieved by starting the first heating device and the second heatingdevice, and therefore a good heat preservation effect can be achieved.

Description

technical field [0001] The invention specifically relates to a food insulation box. Background technique [0002] Milk is a nutritious drink that people like, and it is an indispensable part of people's life. Most of the existing milk is packaged in Tetra Pak, and a certain number of Tetra Pak are stored in cartons. Especially in winter, due to the low external temperature, People have to heat the milk before drinking, because the Tetra Pak milk cannot be directly put into the microwave oven for heating with a box, and the milk can only be poured out and then heated for drinking. Waste of time, people often use microwave ovens to heat milk or other food in time, if the heated milk or food is not drunk or eaten in time, it will become cold again, and it needs to be heated again when drinking or eating, which is not conducive to human health. There are various incubators. Contents of the invention [0003] The object of the present invention is to provide a food incubator ...
