Abstract
The utility model discloses a kind of intelligence lunch box of camping, comprise lunch box body, described lunch box body is provided with semiconductor chilling plate around, described semiconductor chilling plate top is provided with solar panel, described solar panel is electrically connected with lithium battery and control circuit, and described control circuit is also connected with cold and hot selector switch.Power storage that solar panel produces is in lithium battery, for driving heating or the refrigeration of semiconductor chilling plate.Select electric current to flow through semiconductor chilling plate direction by cold and hot selector switch, determine now heating or refrigeration.Metal lunch box is conducive to conduct heat.The utility model, by utilizing solar electrical energy generation to power to semiconductor chilling plate, is realized heating or refrigeration to food, the use of conveniently camping.
Description
Technical field
The utility model relates to electronic component application, relates in particular to a kind of semiconductor chilling plate to be applied to the intelligence that food is carried out to the temperature control lunch box of camping.
Background technology
The now increasing people this stress-relieving activity of having deep love for camping, but in the time camping, except part personage has professional equipment, common people have a meal just to have become a great problem to how to solve.Cook if carry raw material scene, need to carry plurality of devices, carry inconvenience and field and cook difficult; If it is directly edible to be ready to food, both worried food spoilage, be inconvenient to again heat.Therefore, if it is small and exquisite to design a kind of structure, easy to carry, can realize again the food storage of freezing, can heat so that edible lunch box just can well solve a difficult problem of having a meal while camping food again.
Utility model content
Utility model object: the purpose of this utility model is in order to solve deficiency of the prior art, provides a kind of structure small and exquisite, easy to carry can be convenient to preserve to food refrigeration the lunch box that can heat food while preparing to eat in the time not preparing to eat.
Technical scheme: a kind of intelligence described in the utility model lunch box of camping, comprise lunch box body, described lunch box body is provided with semiconductor chilling plate around, described semiconductor chilling plate top is provided with solar panel, described solar panel is electrically connected with lithium battery and control circuit, and described control circuit is also connected with cold and hot selector switch.
As optimization, described semiconductor chilling plate is " U " type structure, and is coated on lunch box body surface.
As optimization, described lunch box body is drawer structure.
As optimization, described lunch box body is Metal lunch box.
Beneficial effect: the utility model, by utilizing solar electrical energy generation to power to semiconductor chilling plate, is realized heating or refrigeration to food, the use of conveniently camping.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit structure block diagram of the present utility model.
Fig. 3 is heating and cooling principle schematic of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model.A kind of intelligence lunch box of camping comprises lithium battery 1, solar panel 2, semiconductor chilling plate 3, Metal lunch box 4, control circuit 5, cold and hot selector switch 6.Solar panel 2 is arranged on lunch box upper surface, lithium battery 1 and control circuit 5 are arranged on lunch box side, and semiconductor chilling plate 3 is designed to U-shaped, are arranged on solar panel below, Metal lunch box 4 is made drawer structure form, is placed in the U-shaped chamber of U-shaped semiconductor chilling plate 3.Cold and hot selector switch is arranged on control circuit 5 outsides.
Fig. 2 is circuit structure block diagram of the present utility model.Solar panel 2 electric energy that produces is stored in lithium battery 1 through DC/DC circuit (part for control circuit 5), for driving semiconductor chilling plate 3.Select electric current to flow through semiconductor chilling plate direction by cold and hot selector switch 6, realize heating or refrigeration to food in lunch box.
Fig. 3 (a) is the utility model refrigeration work principle schematic, and Fig. 3 (b) is the utility model heating work principle schematic.In figure, 31 is the n type material of semiconductor chilling plate PN junction, and 33 is the P-type material of semiconductor chilling plate PN junction, and 32 is semiconductor chilling plate PN junction link, and 1 is lithium battery.Store when food, lithium battery anode connects semiconductor chilling plate n type material, and in the time that semiconductor chilling plate switch on, electric current flows to the P utmost point from the N utmost point, produces the phenomenon of absorbing heat on link 33, by Metal lunch box by heat absorption in food.While preparing edible food, positive source connects semiconductor chilling plate P-type material, and in the time that semiconductor chilling plate is switched on, electric current flows to the N utmost point from the P utmost point, and the heat that sheds on link 33, heats food by Metal lunch box.
