The bottom of the lunch box is provided with a heat element, a battery pack, a power supply socket and a temperature control switch; the lunch box uses the chamber electricity for heating in a chamber with power supply, the food in the lunch box can be heated by controlling the temperature control switch, the lunch box uses battery for heating at outdoor, the food in the lunch box can be heated by controlling the temperature control switch, so that a majority of people requirements can be satisfied.

Description

A kind of heating lunch box
Technical field
The present invention relates to lunch box, relate in particular to a kind of heating lunch box, it belongs to field of tableware.
Background technology
People are owing to go to work at present, and reasons such as tourism need to go out band to serve up the dinner.The lunch box of existing food generally adopts aluminum or plastics; Itself does not have heating function lunch box; Wanting to have the reeky food of good to eat health must place it in the pot or heating in the micro-wave oven; This just needs corresponding place must possess stove, pot or these equipment of micro-wave oven, is not having the situation of these equipment, and people can only eat cool meal.In addition; Use plastics or stainless-steel vacuum heat-insulation and heat-preservation lunch box in addition, its heat insulation effect is not ideal enough, and the plastic, thermal-insulation lunch box can only be kept insulation about three hours; The stainless-steel vacuum Heat insulation lunch-box also can only continue about 6 hours; And it is after long-term the use, and its temperature retention time can not well satisfy the requirement that long-time heat food is preserved well below these times.And its function of having only food container or being incubated food of lunch box that uses at present or incubation canteen, it does not possess the function that temperature of keeping cool food does not raise, and the spy is people when going out to want with some cold drinks fully, and lunch box can't satisfy people's demand.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the present invention provides a kind of heating lunch box, and it adopts stainless steel, is provided with interlayer between the inside and outside courage, and interlayer adopts replaceable medium designs, has reached insulation and has protected cool purpose.
The technical solution adopted for the present invention to solve the technical problems is: a kind of heating lunch box, and it mainly comprises lid, internal layer, shell and interlayer, it is characterized in that: it also comprises heat-insulation layer, heating element heater, opening and seal cover; Lid, inboard and shell constitute one, and interlayer is between inboard and shell, and first heat-insulation layer is positioned at the interlayer both sides and contacts with shell; The interlayer bottom installs a closed sandwich additional, and interlayer inside is provided with heating element heater, is provided with heat transfer medium between closed sandwich and the interlayer; The closed sandwich bottom is provided with second heat-insulation layer, and second heat-insulation layer contacts with outer casing bottom, and the two ends of heating element heater are reserved location means battery pack and outlet respectively; Temperature detect switch (TDS) is positioned at the lunch box side, and its temperature sensing part stretches to interlayer, and the cover top portion side is provided with opening; It is connected with interlayer, and opening part is provided with seal cover.
Said shell and internal layer adopt stainless steel.
The heating lunch box that provides of the present invention, it adopts stainless steel, and it has advantages such as sturdy and durable, not easy to wear; Interlayer adopts the opening design simultaneously, and its inside is provided with hollow design, and people can have more demands of individuals; Add hot water or cold water to its inside; Add hot water and can reach the effect of insulation, add the effect that cold water can reach cold insulation, simultaneously fears are entertained that summer food is placed on for a long time lunch box is inner can be rotten; At the tiny ice cube of the inner heating of hollow interlayer, fresh keeping time that can food and extend.This lunch box is provided with heating element heater, battery pack, outlet and temperature detect switch (TDS) in the bottom, it can have the indoor employing chamber electrical heating of power supply, controls to lunch box inside food through the temperature control opening and heats; Do not have indoor when outdoor; Can adopt the battery heating, and control food heating, thereby satisfy most people's requirement to lunch box inside through temperature detect switch (TDS); Its cost is not high, simply is easy to do and is prone to promote.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of heating lunch box;
Among the figure: 1, lid, 2, internal layer, 3, shell, 4, interlayer, 5, first heat-insulation layer, 6, outlet, 7, second heat-insulation layer, 8, heating element heater, 9, battery pack, 10, temperature detect switch (TDS), 11, opening, 12, seal cover.
The specific embodiment
For understanding this carbon fiber audio amplifier in depth, explain as follows in conjunction with Fig. 1:
A kind of heating lunch box, it mainly comprises lid 1, internal layer 2, shell 3 and interlayer 4, it is characterized in that: it also comprises heat-insulation layer, heating element heater 8, opening 11 and seal cover 12; Lid 1, inboard 2 and shell 3 constitute one, and interlayer 4 is between inboard 2 and shell 3, and first heat-insulation layer 5 is positioned at interlayer 4 both sides and contacts with shell 3; Interlayer 4 bottoms install a closed sandwich additional, and closed sandwich inside is provided with heating element heater 8, closed sandwich and between 4 layers, be provided with heat transfer medium; The closed sandwich bottom is provided with second heat-insulation layer, 7, the second heat-insulation layers 7 and shell 3 pig, and the two ends of heating element heater 8 are reserved location means battery pack 9 and outlet 6 respectively; Temperature detect switch (TDS) 10 is positioned at shell 3 sides, and its temperature sensing part stretches to interlayer 4, and shell 3 top sides are provided with opening 11; It is connected with interlayer 4, and opening 11 places are provided with seal cover 12.
