Abstract
A lunch box with a temperature display function comprises a box cover, a box body, an electric heating layer, a power socket, an LED display screen and a temperature sensor, wherein the box cover is mounted on an opening side of the box body and is openable and closeable freely, one edge of the box cover is connected with the box body, the electric heating layer is mounted below the box body, an electric heating coil is positioned in the electric heating layer, the power socket is arranged on the outer side of the electric heating layer, the LED display screen is mounted on the outer side of the box cover, the temperature sensor is mounted on the inner side of the box cover, and the LED display screen, the temperature sensor and a power source are electrically connected mutually.The lunch box with the temperature display function is simple in structure, convenient to carry, and capable of effectively preventing too high or too low temperature of cooked food with the aid of the temperature display function.
Description
Technical field
The invention belongs to daily necessities field, more particularly to a kind of temperature display lunch box.
Background technology
Lunch box is a kind of box being specifically used to dress food, and also referred to as boxed cassette, big multiplex aluminum, rustless steel, plastics are made.Lunch box includes plastic lunch box, incubation canteen, ordinary lunch-box.Incubation canteen is to have added lagging casing outside common lunch box, has filling foam plastics in inside and outside two-layer, then is plated with metallic film composition at internal layer.The loss of heats is reduced from conduction, radiation, three aspects of convection current.Between lunch box and shell, install again an electric heater unit, the loss of additional heat additional, make food be maintained at certain higher temperature.
But, when being electrically heated, due to uncontrollable temperature, it is easy to make food dry.
Summary of the invention
The present invention solves above-mentioned technical problem, it is provided that a kind of temperature rational in infrastructure, simply compact, scientific and effective display lunch box, the concrete technical scheme of employing is as follows:
A kind of temperature display lunch box, including lid, box body, electric heating layer, supply socket, LED display, temperature sensor, described lid is installed on box opening side, and has a limit to be connected with box body, and can free switch, electric heating layer is installed on below box body, electric heating wire circle in position in electric heating layer, is provided with supply socket outside electric heating layer, LED display is installed on outside lid, temperature sensor is installed on inside lid, and LED display, temperature sensor, power supply are electrically connected to each other.
After switching on power, it is in the temperature sensor inside lid and temperature in box is measured, and by temperature in LED display display box.
The invention has the beneficial effects as follows: this temperature display lunch box structure is simple, it is possible to effectively preventing food from turning cold, be convenient for carrying, temperature shows and can effectively prevent food too high or too low for temperature.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below the specific embodiment of the present invention is described further, but does not limit protection scope of the present invention.
Embodiment 1:
A kind of temperature display lunch box, including lid 1, box body 2, electric heating layer 3, supply socket 4, described lid 1 is installed on box body 2 open side, and has a limit to be connected with box body 2, and can free switch, electric heating layer 3 is installed on below box body 2, electric heating wire circle in position in electric heating layer 3, is provided with supply socket 4 outside electric heating layer 3, LED display 5 is installed on outside lid 2, and temperature sensor 6 is installed on inside lid 2, and LED display 5, temperature sensor 6, power supply are electrically connected to each other.
When needed it is connected with power supply, the electrical heating coil within electric heating layer 3 will persistent fever, maintain the food temperature in box, be in the temperature sensor 6 inside lid 2 and temperature in box measure, and pass through temperature in LED display 5 display box.
Temperature of the present invention display lunch box is described already by specific embodiment.Those skilled in the art can use for reference present disclosure and suitably change its structure and realize other purpose corresponding, its relevant change is all without departing from present disclosure, all similar replacements and change will become apparent to those skilled in the art that and be considered as being included within the scope of the present invention.
