Abstract
The invention relates to a heat-preservation lunch box, comprising a lunch box body. The lunch box body comprises a shell; a box body is arranged in the shell; a plurality of internal slots are arranged in the box body; small holes are formed between the lower surfaces of the adjacent internal slots; a resistance wire mesh is arranged below the box body; resistance wires are arranged in the small holes; a notch is arranged at the lower part of the shell and is internally provided with a storage battery; the storage battery is connected with the resistance wire mesh and the resistance wires; and an upper cover is arranged at the upper part of the shell. The heat-preservation lunch box is simple in structure and convenient to operate, and is long in heat-preservation time and good in heat-preservation effect by adopting the storage battery with large capacity to supply power.
Description
Technical field
The present invention relates to field of tableware, specifically, is a kind of lunch box.
Background technology
The purposes of lunch box in life is very big, and existing lunch box all has other function seldom again except having the effect of filling a bowl with rice.Be placed on the food in the lunch box, the time has been grown and can cool off.Often eat cool food and be unfavorable for people's health, so just the someone has invented with thermos flask and removes the dish of filling a bowl with rice, but the temperature retention time of thermos flask still falls short of, and along with the prolongation of time, the temperature of food can only be more and more lower, and its heat insulation effect is not very desirable.
In sum, if we can invent a kind of lunch box, this lunch box has at every moment all effects of heat tracing, just can solve the unfavorable difficult problem of the warming effect of existing warming lunch box.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of incubation canteen is proposed, this incubation canteen inside is provided with several inside grooves, form aperture between the adjacent inside groove, be provided with heating wire in the aperture, heating wire is powered by battery, and heating wire heats the Heat Conduction Material in the aperture, Heat Conduction Material can continue the food in the heat transferred lunch box inside groove to meal insulation.
The present invention is achieved by the following technical solutions:
Incubation canteen comprises the lunch box body, and the lunch box body comprises a shell, is provided with a box body in the shell, and this box body is provided with several inside grooves, forms aperture between the lower surface of adjacent inside groove, is provided with resistance screen below the box body, is provided with resistance wire in the aperture; Outer casing underpart is provided with a notch, is provided with a battery in the notch, and battery links to each other with resistance screen, resistance wire, and shell upper is a loam cake.
Be provided with thermal conductive material layer between the bottom of box body and the resistance screen, be provided with thermal conductive material layer between the inner surface of aperture and the resistance wire.
Described shell is provided with the insulation switch.
Operation principle of the present invention is: the unfavorable problem of the existing warming effect of warming lunch box ubiquity, trace it to its cause is because the warming principle that adopts mainly is to transmit heat from outside to inside layer by layer, so if the food that holds in the lunch box is many, just be difficult to food heating to inside, thereby cause the warming effect of food undesirable, situations such as the interior cold of the outer heat of the food that heating is come out.The present invention's employing is divided into several inside grooves with the box body that lunch box holds food, and these inside grooves can be divided into several portions to food.Form aperture between the adjacent inside groove, be provided with heating wire in the aperture, heating wire is powered by battery, and heating wire at first heats the Heat Conduction Material in the aperture, and Heat Conduction Material is with the food in the heat transferred lunch box inside groove.Because the present invention's employing is that the food in the lunch box is evenly heated, the resistance wire that is provided with is many more, and heating is just even more, so the interior cool situation of the outer heat of food that existing warming lunch box heats out can not occur.
Beneficial effect: the incubation canteen among the present invention, employing is provided with several inside grooves in the box body inside that holds food, form aperture between the adjacent inside groove, be provided with heating wire in the aperture, heating wire is powered by battery, heating wire heats the Heat Conduction Material in the aperture, and Heat Conduction Material can continue the food in the heat transferred lunch box inside groove to meal insulation.The present invention is simple in structure, and is easy to operate, and what adopt is jumbo storage battery power supply, and temperature retention time is long, high insulating effect.
Description of drawings
Fig. 1 is the surface structure schematic diagram of incubation canteen of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated: present embodiment is being to implement under the prerequisite with the technical solution of the present invention, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment:
Referring to Fig. 1, figure is an incubation canteen, comprises the lunch box body, the lunch box body comprises a shell 1, is provided with a box body 2 in the shell 1, and box body 2 is provided with several inside grooves 21, form aperture between the lower surface of adjacent inside groove 21, be provided with resistance screen 41 below the box body 2, be provided with resistance wire 42 in the aperture; Shell 1 bottom is provided with a notch, is provided with a battery 51 in the notch, and battery 51 links to each other with resistance screen 41, resistance wire 42, and shell 1 top is loam cake 3.
Be provided with thermal conductive material layer between the bottom of box body 1 and the resistance screen, be provided with thermal conductive material layer between the inner surface of aperture and the resistance wire.Be provided with magnesia powder in the thermal conductive material layer of the present invention.
The present invention is when concrete work: contain in lunch box and serve up the dinner, guarantee the accumulator electric-quantity abundance on the lunch box then, open the insulation switch then, battery is given resistance wire and resistance screen power supply, resistance wire and resistance screen are converted to heat energy to electric energy, and heat energy is given meal insulation in the lunch box by adiabator layer.Owing to employing resistance screen and resistance wire among the present invention are incubated to lunch box simultaneously, particularly resistance wire has put in the middle of the lunch box box body, and the employing of the box body in lunch box branch groove layout, so just can make heating more even, heats better effects if.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
