Multifunctional environment-friendly lunch box with intelligent temperature control function

Abstract

The invention discloses a multifunctional environment-friendly lunch box with an intelligent temperature control function. The multifunctional environment-friendly lunch box comprises a lunch box bodyand a top cover. The lunch box body is composed of the top cover and a containing bin, the top of the containing bin is rotationally connected with the top cover through a hinge, and a heat separation plate is clamped and fixed in the containing bin. According to the multifunctional environment-friendly lunch box, when a user needs to carry out heat preservation on food, a control switch is powered on, a temperature sensor can detect the temperature in the lunch box body; when the temperature is lower than 45 DEG C, the temperature sensor can transmit data to a temperature controller, and thetemperature controller can make a heating plate to heat a food storage box; when the food storage box is heated to 70 DEG C, the temperature sensor can transmit data to the temperature controller, and the heating plate is made to stop working. The intelligent temperature control device can carry out scientific and reasonable heating according to the temperature condition of food, and meanwhile electric energy waste can be avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection lunch boxes, in particular to a multifunctional environmental protection lunch box with intelligent temperature control. Background technique [0002] The thermal insulation lunch box is an ordinary lunch box with a thermal insulation shell, which is filled with foam plastic in the inner and outer layers, and then coated with a metal film on the inner layer. Reduce heat loss from three aspects: conduction, radiation, and convection. An electric heating device is installed between the lunch box and the shell to supplement the loss of heat and keep the food at a certain high temperature. It has a long heat preservation time and can be reheated when you want to eat; fashionable appearance and portable; Compared with the insulated lunch boxes on the market, the price is relatively affordable, the product is green and environmentally friendly, energy-saving and beautiful.

AI Technical Summary

Problems solved by technology

[0003] Many lunch boxes are simple in structure and cannot be used for heat preservation of food. Although many lunch boxes have heat preservation devices, they cannot carry out scientific and reasonable heat preservation treatment according to the temperature of the food, so that the food is heated from the beginning to the end of the lunch box, resulting in Waste of electric energy, there are many lunch boxes that cannot store food in a vacuum. After the food is placed in the lunch box for a period of time, the food is easy to deteriorate. There are also some lunch boxes that are not equipped with functional devices for the convenience of users.
