Abstract

The utility model provides a based on active heat preservation lunch -box of phase change material, passes through the heat preservation of phase change material constant temperature heat release and battery initiative heating realization meal, mainly includes constitutions such as box body, phase -change thermal material, battery, heating plate, heat insulation layer, switch, USB interface. When this lunch -box uses, can at first store the heat with boiling water heating melting phase -change thermal material, pour out the boiling water afterwards, add the meal, phase change material phase transition process is felt relieved for the meal heating, simultaneously, adopts battery initiative heating as required, and the battery adopts the USB interface. The utility model discloses keep the constant temperature of meal with less energy consumption, have practicality, energy -conserving and advantage such as conveniently.

Description

A kind of based on phase-change material active heat-insulating lunch box
Technical field
This utility model relates to a kind of lunch box, particularly relates to a kind of based on phase-change material active heat-insulating lunch box.
Background technology
Incubation canteen is a kind of important tableware in daily life, is especially student, working clan and traveller etc. Warm food provide great convenience.Incubation canteen is by certain adiabatic heat-insulation measure or supplementary external heat source The insulation of food is realized etc. mode.At present, different types of incubation canteen is already present on the market, but its The design of middle product rarely has from the point of view of energy-conservation, and the most most product is to use reheating after cooling Passive mode.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of employing phase-change material as heat storage medium also In conjunction with accumulator actively heating, it is possible to keep the active based on phase-change material of food temperature with less energy consumption Incubation canteen.
In order to solve above-mentioned technical problem, including lid and box body, surrounding and bottom in described box body are arranged There are thermal insulating warm-keeping layer, the middle part of described box body to be provided with an inner bag, fill out between described thermal insulating warm-keeping layer and inner bag Being filled with phase-change material layers, be provided with electric heating sheets in described phase-change material layers, described electric heating sheets is by arranging Storage battery power supply on box body.
Connect a handle outside described box body, described accumulator, described electric power storage are installed in the middle of described handle Being provided with a USB charge port on pond, described heating plate is connected by wire with accumulator, on described wire One switch is installed.
Described electric heating sheets is arranged on the bottom of inner bag.
Described inner bag is clear glass inner bag.
Described phase-change material layers is solid-liquid phase change material layer.
Use technique scheme based on phase-change material active heat-insulating lunch box, first, with boiled water by phase transformation Material heating and melting, can observe thawing situation through glass inner bag, then, pour out boiled water, add needs The food of insulation, and lid is covered tightly reality, the thermal insulating warm-keeping layer of incubation canteen will farthest reduce heat Loss, meanwhile, the phase-change material melted will discharge Topography food at a constant temperature, because institute Selecting the melting temperature of phase-change material at about 60 DEG C, the temperature difference relatively low between lunch box and environment reduces heat loss. If temperature retention time is longer, user can open the switch on handle, and the electric energy of accumulator is used heating Sheet is converted into bottom heat actively lunch box capable of heating.For convenience, accumulator uses USB interface, and user can To utilize portable power source, automobile and computer etc. at one's side to charge for accumulator.This utility model has structure and simplifies, Convenient and practical and energy-conservation etc. a little.
In sum, this utility model is that one discharges Topography based on phase-change material under conditions of constant temperature Lunch box, and use accumulator actively to heat the practicality of food, energy-conservation and convenient incubation canteen as required.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Seeing Fig. 1, the one that this utility model provides is based on phase-change material active heat-insulating lunch box, including one Lid 1 and box body 2, the surrounding of described box body 2 and bottom are disposed with thermal insulating warm-keeping layer 3, described box body 2 Center have a glass inner bag 4, be filled with solid phase between described thermal insulating warm-keeping layer 3 and glass inner bag 4 Becoming material 5, described box body 2 connects a handle 6, installs an accumulator 7 in the middle of described handle 6, Described accumulator 7 has a USB interface 8, arranges a heating plate 11 in described phase-change material 5, Described heating plate 11 is connected by wire 9 with accumulator 7, and described wire 9 is installed a switch 10.
Operation principle, with reference to Fig. 1, during beginning, pours boiled water in glass inner bag 4, melts solid phase completely Become material 5, subsequently, pour out boiled water, add food, and cover tightly lid 1, open switch then according to needs 10, accumulator 7 exports electric current through wire 9, is changed in heat glass inner bag 4 by heating plate 11 Food, thermal insulating warm-keeping layer 3 stops the heat exchange of lunch box and environment, finally, after temperature retention time terminates, closes Swap switch 10.When the electricity in accumulator 7 is few, connected the USB of power supply and accumulator 7 by data wire Interface 8 charges for accumulator 7.
