Abstract
The utility model relates to a lunch box. The lunch box is characterized in that an insulating device is arranged at the bottom part of a box body; ventilating holes are arranged between the inner wall and the outer wall of the box body; the insulating device consists of an electric storage heating device and an auxiliary device; the auxiliary device is a container full of water; an arc shape is formed on the container and is provided with a ventilating hole; the electric storage heating device is an electric heater with a charging device; the insulating device is movably connected on the box body. By adoption of the scheme, the insulating time of the insulating lunch box is long.
Description
Technical field
The utility model relates to a kind of lunch box.
Background technology
At present, the Along with people's growth in the living standard, various home appliances are complete on the market.Lunch box is a household appliance, particularly incubation canteen commonly used in the household, is requisite insulation instrument in the life.Present most incubation canteen all is to utilize the principle of insulation of kettle to reach heat insulation effect; So-called incubation canteen generally is the container that is added the food that vacuum layer or thermal insulation layer are made by double-layer plastic or stainless steel; Lid is arranged at the top; Seal tightly, vacuum layer or thermal insulation layer can make and be contained in inner food and delay heat radiation, to reach the purpose of insulation.Incubation canteen is from the vacuum flask development, and heat preservation principle is the same with vacuum flask.The propagation of heating power has three kinds of approach: radiation, convection current and transmission.The inner bag of silver color can reflect radiation of heat in the vacuum flask, and the vacuum layer of cup body or thermal insulation layer can be blocked the transmission of heat.Though this kind structure can reach certain heat insulation effect, can not be incubated the sufficiently long time, the time is long, has just lost heat insulation effect.
At present, the having a wide reach of electrical heater applications, the operation principle of electric heater changes into heat energy to electric energy exactly, and it is heated agent.Insulating pot is exactly the product that wherein the most representative electric energy changes into heat energy.Thereby it is exactly to produce a large amount of heat with the resistance of resistance wire to make the water ebuillition of heated.
The utility model content
The utility model provides a kind of a kind of incubation canteen that utilizes electric energy to reach effective heat insulation effect according to above-mentioned deficiency.
For realizing above-mentioned purpose, the technical scheme of the utility model is an incubation canteen, and the box body bottom of described incubation canteen is provided with attemperator, has passage between the box body inside and outside wall.
Described attemperator stores heater by electricity and servicing unit is formed.
Described servicing unit is the container by filled with water, and the top camber of described container has passage on it, and described electricity stores the electric heater that heater is the band charging device.
Described attemperator is movably connected on the box body.
The beneficial effect of technique scheme is: incubation canteen can utilize the electric energy of storage that water is heated; Thereby reach heat insulation effect; Because attemperator and box body flexibly connect, can directly heat box body with fire or electromagnetic oven simultaneously, temperature retention time is long.
Description of drawings
Fig. 1 is the utility model overall structure sketch map.
The specific embodiment
Do bright specifically below in conjunction with the accompanying drawing and the specific embodiment to the utility model.
By shown in Figure 1, box body 1 bottom of the utility model incubation canteen is provided with the attemperator electricity and stores heating 6, and the top that the attemperator electricity stores heating 6 is the container 4 that the band pore is filled with water, and the top of the container 4 that the band pore is filled with water is a circular arc 5, has passage 3 on it; Have passage 8 between box body 1 inside and outside wall; The attemperator electricity stores heating 6 and passes through bayonet socket 7 on box body 1; Rice container 2 is being placed in lunch box 1 inside.
