The refrigeration and heating lunch box provided by the invention has the functions of both heating and refrigeration, thereby being convenient to use.
Description
Technical field
The present invention relates to a kind of lunch box, a kind of heating/cooling lunch-box that can heat food and freeze of specific design.
Background technology
The lunch box used on the market at present has insulation, and have heating, but when hot day, such lunch box can not make food Keep the quality and freshness, people has eaten and poisoned by food sometimes.
Along with social progress, the step of life is more and more faster, and the operating pressure of working people is large, and rhythm of life is nervous, and every day is also in the puzzlement enduring lunch and overtime work dinner to the fullest extent.
In actual life, the food in dining room is dull, and total mouth difficulty is adjusted; The packed meal taken out is unhygienic, and the element that foam food boxes contain a large amount of harm health exists; If it is larger to go out restaurant economic pressures of having a meal every day, and food-safety problem also makes people worry, and is not fine, often has cool meal by the effect of common incubation canteen.The patient of hospital, because family is to hospital's road, is also difficult to have tasty food, is also difficult to find the restaurant meeting oneself taste in driving way or in countryside, or very expensive, unhygienic.
Existing lunch box is regulable control temperature or fresh-keeping not easily, causes and because temperature is too high, the nutrition of food and food is destroyed when heating, the too low taste that also can affect food of temperature of refrigeration.
Summary of the invention
The object of the invention is: solving at present lunch box on the market can only heating and thermal insulation and can not the difficult problem of refrigerating fresh-keeping.Refrigerating fresh-keeping when food in lunch box is not eaten at short notice, and the heating when soon eating.
For achieving the above object, a kind of heating/cooling lunch-box of the present invention, comprise power supply, circuit commutation temperature controller, cold and hot, Rice container and radiator, described power supply is connected with electric current commutation temperature controller, described electric current commutation temperature controller is connected with cold and hot, Rice container is positioned on cold and hot, and radiator is positioned under cold and hot.
Wherein described in an embodiment cold and hot there is first surface and second surface, described first surface is a face, and described second surface is b face.
Wherein described in an embodiment cold and hot there is thermal insulation layer, described thermal insulation layer is between described a face and b face.
Described in an embodiment cold and hot has cold and hot first power interface, cold and hot second source interface wherein, on described electric current commutation temperature controller, correspondence has electric current commutation temperature controller first power interface, electric current commutation temperature controller second source interface.
The temperature controller of the commutation of electric current described in an embodiment wherein have 2 groups of switches, one group of switch is battery main switch, another group switch is power interface switch, and described power interface switch can turn-on current commutation temperature controller first power interface or electric current commutation temperature controller second source interface.
When commutation temperature controller first power interface of power interface switch connection electric current described in an embodiment and turn-on current commutation temperature controller second source interface, electric current commutation temperature controller gives the cold and hot sense of current provided contrary wherein.
Invention increases lunch box refrigerating fresh-keeping function, make the people of band meal no longer have food deterioration, can facilitate relieved edible, and heating and refrigeration are made of one, easy to use, cost is low.
