Abstract
The invention relates to a heat-insulating lunch box. A heat insulating device is arranged at the bottom of a box body, an air vent is arranged between inner and outer walls of the box body, the heat insulating device comprises an electric storage heating device and an auxiliary device, the auxiliary device is a container full of water, the upper part of the container is of an arc shape with an air vent, the electric storage heating device is an electric heater with a charging device and the heat insulating device is movably connected with the box body. Based on the technical scheme, the heat-insulating lunch box has the advantage of long heat insulating time.
Description
Technical field
The present invention relates to a kind of lunch box, what be specifically related to is a kind of incubation canteen.
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.
Summary of the invention
The present invention 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, technical scheme of the present invention 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.
The top camber of described container has passage on it.
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 an overall structure sketch map of the present invention.
The specific embodiment
Do bright specifically below in conjunction with the accompanying drawing and the specific embodiment to the present invention.
By shown in Figure 1, box body 1 bottom of incubation canteen of the present invention 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.
Claims (6)
