Abstract

The utility model discloses a solar heat-insulation lunch box comprising a box body and a box cover. A heating layer and a power supply layer are arranged at the lower end of the box body, a cavity is arranged between the heating layer and the power supply layer, a solar cell panel is arranged in the cavity, and the solar cell panel is electrically connected with the heating layer and the power supply layer by leads so as to form a heating control circuit. As the solar heat-insulation lunch box directly utilizes the solar energy for heating meal, the solar heat-insulation lunch box saves energy resources, does not pollute environment, occupies small spaces, and is economical, practical and easy to carry. Due to the special design of the solar heat-insulation lunch box, the solar cell panel can be folded or unfolded, the light condensing area of the solar cell panel can be enlarged so as to increase the electric energy production and provide sufficient electric energy for a rechargeable battery in the box body, so that the energy consumption of the heating layer can be met so as to transfer the energy to the box body for heating and thermal insulation. Therefore, as for the solar heat-insulation lunch box, not only a large quantity of energy valuable resources are saved, but also the long-time heating and thermal insulation can be implemented in the wild or areas short of electric energy without mains supply, the life of people is facilitated greatly, and further the health index of the human body is improved.

Description

The warming solar energy lunch box

Technical field

The utility model relates to a kind of lunch box, particularly a kind of warming solar energy lunch box.

Background technology

The most structure of the incubation canteen of Xiao Shouing is simpler in the market, has only the function of insulation, and do not have the heating function, people after lunch box splendid attire food, after a while food will cool off naturally and influence edible, be unfavorable for the person health.In order to address this problem, therefore electrically heated lunch box has appearred in prior art, this electrical heating lunch box has overcome food to a certain extent and has cooled off and influence edible shortcoming, but the mains-supplied that it adopts, not only poor stability, power consumption is high, inconvenience is carried, and only uses in the place that civil power is being arranged, be carried into the field or do not have civil power can for the place use, lunch box will lose the effect of heating warm-keeping, thereby brings very big inconvenience to people.

The utility model content

The purpose of this utility model provides a kind of safe and reliable, energy-conserving and environment-protective, is easy to carry, and is not subjected to any environmental limitations, the warming solar energy lunch box that can heat whenever and wherever possible.

For achieving the above object, the utility model adopts following technical scheme: a kind of warming solar energy lunch box, comprise box body and lid, be provided with heating layer and bus plane in the lower end of box body, be provided with a cavity between heating layer and the bus plane, the built-in solar panel that is placed with of cavity, described solar panel is by lead and heating layer and bus plane electric connection formation heating control circuit.

Preferably scheme is, formed with aluminium foil or carbon film conductive layer by being provided with between polyimide base film and the polyimides facial mask according to heating layer described in the utility model with two electrodes, and be 3 Ω-50 Ω wherein in two interelectrode resistance values.

Preferred scheme is, is that the surface of two housings is provided with the copper indium gallium selenium solar hull cell according to solar panel described in the utility model, connects and composes the structure that two housings can be superimposed or be launched at a edge that two housings links to each other with rotating manner.

Preferred scheme is, is to be filled diode, charged and discharged circuit and control circuit and electrically connect successively and place in the box body by rechargeable battery, counnter attack according to bus plane described in the utility model, is provided with LED and shows and function key outside box.

The utility model directly utilizes solar energy to heat to food, saves the energy, and is economical and practical, non-environmental-pollution, and it is little to take up room, and is easy to carry about with one.Increased the function that solar panel is collapsible or launch with its exclusive design again; folded concealed is in box body when not using; both protected solar cell injury-free; avoid again reducing light energy use efficiency because of the solar cell long term exposure; can in box body, extract solar panel formation expansion shape out when needing to use; make the collection area of solar panel enlarge and the increase generated energy; sufficient electric weight is provided for the rechargeable battery in the box body; with the energy consumption that satisfies heating layer and then pass to box body and give heat tracing; therefore both saved a large amount of valuable energy; can make people at the power-shortage area that does not have civil power to supply again; open-air or the place that keeps clear of electrical network also can the long-time heating insulation; greatly facilitate people's life, thereby improve the health index of human body.
