Abstract

The utility model provides a multifunctional solar heating insulated lunch box which comprises a solar panel, a box cover, an outer shell, a middle shell, an inner shell, a storage battery, a heating wire, a water storage layer, a vacuum layer, a lunch box main body, a charging jack, a storage battery switch, a lead wire, a metal contact, a water storage layer cover, a movable handle and an insulation layer, wherein the storage battery can be charged through the solar panel or a power source, and the storage battery supplies electric power to the heating wire to heat the water storage layer, so that hot drinking water can be provided while the food is heated and thermally insulated. A dual-layer vacuum shell body is adopted between the middle shell and the outer shell, so that the thermal insulation effect is better, and the multifunctional solar heating insulated lunch box is particularly suitable for people needing to bring lunch in daily work or travelling outside.

Description

A kind of multifuctional solar heated heat-preserving lunch box

Technical field

The utility model relates to a kind of lunch box, relates in particular to a kind of multifuctional solar heated heat-preserving lunch box.

Background technology

When people are on duty, usually need to be with meal band water, but now many lunch boxes do not have the function of heating, more do not have manufacture hot water's function, what people often ate is cool meal cold dish, on the one hand the food cold do not have mouthfeel, also be unfavorable on the other hand health.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 Multifunctional 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 utility model provides a kind of multifuctional solar heated heat-preserving lunch box, and it is comprised of solar panel, lid, shell, mesochite, inner casing, battery, heating wire, reservoir bed, vacuum layer, lunch box main body, charging jack, battery switch, wire, hard contact, reservoir bed lid, movable handle and insulating barrier.Solar panel is positioned on the lid, and solar panel, battery, battery switch, charging jack are connected by wire with heating wire; Form vacuum structure between shell and the mesochite; Hard contact is between lid and shell; Movable handle is at the shell two ends; Insulating barrier is positioned at housing exterior; Totally four of hard contacts, wherein two link to each other with battery, and two link to each other with heating wire.Be reservoir bed between mesochite and the inner casing, and be provided with the reservoir bed lid of screw thread in the reservoir bed upper end.Shell, mesochite, inner casing are made by stainless steel, and shell is done insulation and processed.

In the time of sun-drenched out of doors, utilize solar panel to charge in batteries, by battery heating wire is powered, heating wire produces the reservoir bed between heat heating mesochite and the inner casing, realizes also can providing drinking hot water simultaneously to the food heat tracing; Can be charge in batteries by power supply also; Can also in reservoir bed, directly add hot water, heat is provided.Because stainless steel has good thermal conductivity, shell, mesochite, inner casing are made by stainless steel, and shell does insulation and process, 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 powered to heating wire.

The beneficial effects of the utility model are: can directly utilize solar energy to power for heating wire, lunch box capable of heating 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, needing in the routine work to be suitable for meal and the librarian use of travelling outdoors.

Description of drawings

Fig. 1 is overall structure schematic diagram of the present utility model;

Fig. 2 is longitudinal profile schematic diagram of the present utility model;

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 wire, 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 utility model:

In the drawings, make respectively shell 3, the mesochite 4 and inner casing 5 of uncovered with stainless steel, shell 3 is done insulation and is processed; Heating wire 7 closely links to each other with mesochite 4, and is drawn out to the upper end of shell 3 by wire 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, reservoir bed can be covered 15 and screw on, will vacuumize between mesochite 4 and the shell 3 again.

Utilize the method for making shell 3, make one and the matched double-deck lids 2 of shell 3 sizes, solar panel 1 is fixed on lid 2 tops, between lid 2 ectonexine spaces, put into battery 6, and with wire 13 solar panel 1 is connected with battery 6, again the both positive and negative polarity of battery 6 is drawn with wire 13 respectively, 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 wire 13 with battery 6; Opposite side at lid 2 is equipped with battery switch 12.

Food is put into lunch box main body 10, the close lid 2 of lunch box is positioned under the sunlight, because hard contact 14 places adopt automatic contacting, when closing lid 2, battery 6 and heating wire 7 contact by hard contact, automatically form the closed-loop path, and 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 by charging jack 11 also.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.Owing to being vacuum layer 9 between mesochite 4 and the shell 3, reduce thermal convection current, reduce thermal loss, also can play good insulation effect to water and food.
