Abstract
The invention provides a multifunctional solar energy heating and heat preservation lunch box which comprises a solar panel, a box cover, an outer casing, an intermediate casing, an inner casing, a storage battery, a heater strip, a water storage layer, a vacuum layer, a lunch box main body, a charging jack, a storage battery switch, a conducting wire, a metal contact, a water storage layer cover, a movable handle and an insulating layer. According to the invention, the storage battery can be charged through the solar panel and can also be charged by a power supply; the storage battery supplies power to the heater strip to heat the water storage layer, so that food can be heated and kept warm, and hot water for drinking can be supplied; and a double-layered vacuum casing is arranged between the intermediate casing and the outer casing, so that the heat preservation effect is better, and the multifunctional solar energy heating and heat preservation lunch box is very suitable for people needing to take food in daily work and people going out for playing.
Description
Technical field
The present invention relates to a kind of lunch box, relate in particular to a kind of multifuctional solar heat tracing lunch box.
Background technology
When people are on duty, usually need be with meal band water, but many lunch boxes do not have the function of heating now, more do not have manufacture hot water's function, what people often ate is cool meal cold dish, and food is cool does not on the one hand have mouthfeel, is unfavorable for health on the other hand yet.The lunch box that some heating are arranged in the market, what have can only use electrical heating, and what have passes through the heating of chemical reaction or fuel, but uses chemical fuel to pollute the environment.Solar energy is a kind of clean energy resource, and the comparative maturity that its technology has developed conveniently is easy to get.The multi-functional heating lunch box that power supply combines with solar energy is not also sold on the market.
Summary of the invention
In order to solve above problem; The present invention provides a kind of multifuctional solar heat tracing lunch box, is made up of solar panel, lid, shell, mesochite, inner casing, battery, heating wire, reservoir bed, vacuum layer, lunch box main body, charging jack, battery switch, lead, hard contact, reservoir bed lid, movable handle and insulating barrier.
Technical scheme of the present invention is: in the time of sun-drenched out of doors, utilize solar panel to charge in batteries, by battery heating wire is supplied power, heating wire produces the heat reservoir bed, realizes also drinking hot water can being provided simultaneously to the food heat tracing; Can be charge in batteries also through power supply; Can also in reservoir bed, directly add hot water, heat is provided.Because stainless steel has good thermal conductivity, shell, mesochite, inner casing are processed by stainless steel, and shell does insulation and handle, and prevent conduction.Be vacuum layer between mesochite and the shell, reduce thermal loss.Movable handle is conveniently mentioned lunch box, and is convenient from the outside pouring of reservoir bed.The reservoir bed upper end is provided with the reservoir bed lid of screw thread, guarantees the sealing of reservoir bed.When closing lid, battery hard contact and heating wire hard contact UNICOM form the closed-loop path; Battery switch is set on the lid, can opens at any time or close, when switch cuts out, be charge in batteries, when switch open, battery is then supplied power to heating wire.
The invention has the beneficial effects as follows: can directly utilize solar energy to supply power for heating wire, the heating lunch box is saved the energy; Also can directly utilize power supply to be charge in batteries; Reservoir bed also can provide drinking hot water when playing the heat tracing effect, be suitable for personnel's use that needs are with meal and are travelled outdoors in the routine work.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention;
Fig. 2 is a longitudinal profile sketch map of the present invention;
Among the figure 1 be solar panel, 2 for lid, 3 for shell, 4 for mesochite, 5 for inner casing, 6 for battery, 7 for heating wire, 8 for reservoir bed, 9 for vacuum layer, 10 for the lunch box main body, 11 for the charging jack, 12 for battery switch, 13 for lead, 14 for hard contact, 15 for reservoir bed lid, 16 for movable handle, 17 be insulating barrier.
The specific embodiment
Accompanying drawings, set forth the specific embodiment of the present invention:
In the drawings, process the shell 3, mesochite 4 and inner casing 5 of uncovered respectively with stainless steel, shell 3 is done insulation and is handled; Heating wire 7 closely links to each other with mesochite 4, and is drawn out to the upper end of shell 3 by lead 13, links to each other with hard contact 14; Shell 3, mesochite 4, inner casing 5 are nested together successively; Weld with corrosion resistant plate shell 3, mesochite 4, inner casing 5 upper ends; Wherein reserve a screwed circular hole between inner casing 5 and the mesochite 4, can reservoir bed be covered 15 and screw on, again with vacuumizing between mesochite 4 and the shell 3.
Utilize the method for making shell 3; Process one and the matched double-deck lids 2 of shell 3 sizes; Be fixed on lid 2 tops to solar panel 1, between lid 2 ectonexine spaces, put into battery 6, and solar panel 1 is connected with battery 6 with lead 13; Draw the both positive and negative polarity of battery 6 with lead 13 respectively again, link to each other with hard contact 14; In a side of lid 2, the jack 11 that charges of packing into links to each other charging jack 11 with lead 13 with battery 6; Opposite side at lid 2 is equipped with battery switch 12.
Food is put into lunch box main body 10, and the lid 2 of the lunch box that closes is positioned under the sunlight; Because hard contact 14 places adopt automatic contact, when closing lid 2, battery 6 and heating wire 7 contact through hard contact; Automatically form the closed-loop path, 1 pair of battery 6 of solar panel charges, again by 7 power supplies of 6 pairs of heating wire of battery; It is the reservoir bed heating that heat is provided, and reservoir bed heats up simultaneously, is the food heating.Can be charge in batteries also through charging jack 11.Battery switch 12 can be opened or close at any time, and decision is to heating wire 7 power supplies or to battery 6 chargings.Because between mesochite 4 and the shell 3 is vacuum layer 9, reduce thermal convection current, reduce thermal loss, also can play good insulation effect to water and food.
