The utility model is in particular suitable for people with fieldwork.

Description

The solar energy lunch box

Technical field

The utility model belongs to a kind of daily necessities, specifically, is a kind of solar energy lunch box.

Background technology

After the existing lunch box splendid attire food, food can cool off by nature after a while, to the edible inconvenience of bringing of people.People have designed the lunch box that has electric heater unit in order to address this problem.But this only uses in the place that power supply is arranged.When people work in the open air, both there be not power supply, there is not cooking stove yet, without any heater, can't give the heating of the food in the lunch box, people have only eat cold rice.This problem ubiquity can not solve for a long time, has brought very big inconvenience to people.

The utility model content

The purpose of this utility model is to be to provide a kind of electric energy and fuel of not needing, and does not need miscellaneous equipment, does not pollute the solar energy lunch box that can heat to food automatically.

The utility model thes contents are as follows:

The solar energy lunch box is made up of lunch box 4, cover of the lunch box 2, protection box 9, and lunch box 4 and cover of the lunch box 2 have internal layer 5 and skin 7, scribble the black heat-sink shell on the internal layer 5, are vacuum layer 6 between the internal layer 5 and outer 7.

Between outer field bottom of lunch box and the protection box 9 neonychium 10 is arranged.

Outside lunch box outer 7 and the neonychium 10 guipure 8 is arranged.

The solar energy lunch box is to change solar energy into heat energy to heat to food.Lunch box 4 and cover of the lunch box 2 are layer glass and make, and scribble the black heat-sink shell on the wall of internal layer 5, use the novel magnetron sputtering gradual change aluminium one nitrogen/aluminium sun of Tsing-Hua University's invention to select absorber coatings, in order to absorb solar heat.Between the inside and outside layer is vacuum layer 6, and the food temperature that heated in order to protection can not be cooled.Cover of the lunch box and lunch box are double-layer vacuum, internal layer scribbles the black heat-sink shell, and structure is identical, can absorb heat and be incubated.

Between outer field bottom of lunch box and protection box 9, neonychium 10 is arranged.Neonychium 10 selects for use rubber-like materials such as rubber, plastics to make.The effect of neonychium has two: one side cover glass lunch box can make lunch box stablize on the other hand and stand.

Protection lid 1 is arranged on the protection box 9 of the present utility model, and protection box 9 and protection lid 1 can be used glass, and transparent plastic is made, and also can make with metal material.

In the outside of lunch box 4 and neonychium 10, a guipure 8 is arranged, be formed by connecting by 4-8 root strap or rope.Mention guipure, lunch box is taken out from protection box 9, place it on the ground; Perhaps carry in hand, or back on the body, expose to sunlight, absorb solar energy.If protection box 9 adopts transparent material to make, then do not need to mention guipure 8, do not need lunch box 4 is taken out from protection box 9, can directly absorb solar energy.

Can also be provided with inner box 3 in the utility model solar energy lunch box, in order to the food packing.The diameter of inner box 3 is slightly less than lunch box 4 internal diameters.

The utlity model has and do not need electric energy, do not need fuel and other firing equipment, directly utilize solar energy to food heating, the saving energy, economical and practical, advantages such as non-environmental-pollution.The people that are particularly useful for field work.
