Description
Technical field
This utility model relates to incubation canteen field, is specifically related to a kind of frequency conversion eddy heating for heating incubation canteen.
Background technology
Incubation canteen, especially improves temperature or insulation to food in lunch box, it is possible to realizes use in some scenarios, therefore, has preferable using value.Traditional incubation canteen has plenty of use vacuum principle, and heat radiation is slow, and effect is not notable, has plenty of use electric-heating-wire-heating, but does not accomplishes that temperature regulates, it is also possible to causes and be sticking, and it is not very convenient to use.
Utility model content
For overcoming deficiency of the prior art, this utility model provides can actively regulate temperature, a kind of frequency conversion eddy heating for heating incubation canteen temperature maintained.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of frequency conversion eddy heating for heating incubation canteen, including heating unit, supply unit, switch element, lunch box body, it is characterized in that: described lunch box body is three-decker, it is respectively upper strata, intermediate layer, lower floor, described heating unit is arranged on intermediate layer, heating unit includes eddy current heating wire, heat-conducting layer, temperature sensor, eddy current heating wire winding is on heat-conducting layer, it is provided with control unit on described supply unit, control unit includes singlechip controller and miniature converter, described supply unit is the most external independent of lunch box, miniature converter and eddy current heating wire, switch element is interconnected by supply unit, singlechip controller and temperature sensor, miniature converter, switch element is interconnected by supply unit.
Further, described lunch box body being additionally provided with thermal insulation layer, described thermal insulation layer is arranged between lower floor and intermediate layer.
Further, described switch element includes that plug and temperature arrange panel, and described plug is embedded in lunch box body lower floor.
Seen from the above description, a kind of frequency conversion eddy heating for heating incubation canteen environmental protection and energy saving that this utility model provides, the efficiency of heating surface is high, can be incubated food at any time, the daily life being convenient for people to.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of frequency conversion eddy heating for heating incubation canteen.
Fig. 2 is the front view of this utility model a kind of frequency conversion eddy heating for heating incubation canteen.
Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
nullAs depicted in figs. 1 and 2，A kind of frequency conversion eddy heating for heating incubation canteen，Including heating unit 1、Supply unit 2、Switch element 3、Lunch box body 4，Lunch box body 4 is three-decker，It is respectively upper strata 41、Intermediate layer 42、Lower floor 43，Described heating unit 1 is arranged on intermediate layer 42，Heating unit 1 includes eddy current heating wire 11、Heat-conducting layer 12、Temperature sensor 13，Eddy current heating wire 11 is wrapped on heat-conducting layer 12，It is provided with control unit on described supply unit 2，Control unit includes singlechip controller 21 and miniature converter 22，Outside described supply unit 2 is independent of lunch box body 4，Miniature converter 22 and eddy current heating wire 11，Switch element 3 is interconnected by supply unit 2，Singlechip controller 21 and temperature sensor 13、Miniature converter 22、Switch element 3 is interconnected by supply unit 2，Thermal insulation layer 44 it is additionally provided with on lunch box body 4，Described thermal insulation layer 44 is arranged between lower floor 43 and intermediate layer 42，Switch element 3 includes that plug 31 and temperature arrange panel 32，Described plug 31 is embedded in lunch box body 4 lower floor 43.
As shown in the figure, a kind of frequency conversion eddy heating for heating incubation canteen that this utility model provides, in use, set to set on panel 32 in temperature and need the temperature of insulation, lunch box body 4 is heated by eddy current heating wire 11, it be arranged on the temperature sensor 13 in intermediate layer 42 by temperature transfer to singlechip controller 21, singlechip controller 21 controls miniature converter 22 and heats eddy current heating wire 11, heat-conducting layer 12 transfers heat to lunch box body 4, thermal insulation layer 44 can be by shield heat away, the main body of lunch box lower floor 43 would not be generated heat, once temperature less than the value set, temperature sensor 13 passes information to singlechip controller 21, repeat above operation.
Above are only some detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design that this utility model carries out unsubstantiality, the behavior invading this utility model protection domain all should be belonged to.
