Abstract
The utility model relates to a lunch-box warming device belonging to electric heater, which mainly comprises a box body (2) and a box cover (1) of the warming device. A heat dissipation plate, an upper insulating plate, an electrothermal membrane, a lower insulating plate and a heat insulation plate are arranged at the bottom of the inner chamber of the box body, and a power socket is arranged on the end wall at the bottom of the box body. The utility model adopts the electrothermal membrane as the warming body and has the advantages of energy saving and simple structure, which is suitable to warm the lunch-boxes with food for people on work.
Description
The utility model relates to a kind of lunch box heater, belongs to electric heater.
Usually people's tape food of having a meal when if no steaming equipment does not steam lunch box, just is unable to eat hot food, makes the people feel very inconvenient, just need look for other heating appliances in addition.
The purpose of this utility model is to provide a kind of lunch box heater that utilizes city's power supply for the energy.Known to the applicant, existing incubation canteen, electric heating mess tin kind are more, but incubation canteen is only applicable to the meal insulation usefulness of heat, and electric heating mess tin then is the heater that adopts electrothermal tube, heating wire and so on, and the lunch box heater that the utility model relates to is the heater made from Electric radiant Heating Film.
Structure of the present utility model is such, design has the metallic heat radiating plate that is complementary with the box body inner chamber at lunch box heater inner bottom part 1.5cm place, the heat sink lower surface is close to ceramic insulation substrate, below the lower surface coating one deck Electric radiant Heating Film of ceramic insulation substrate, Electric radiant Heating Film is the insulation board of ceramic material.Its complementary space below the metallic heat radiating plate is the alumina silicate fibre thermal insulation board, and supply socket is installed in the bottom of box body end wall.
Advantage of the present utility model is to have adopted the Electric radiant Heating Film new technology, has shown the energy-conservation characteristics of this lunch box heater, and a common lunch box food is warmed to more than 70 ℃ from the chamber, and power consumption only is 0.05 to 0.1 degree.
The thin thickness volume that is also advantageous in that Electric radiant Heating Film of the present utility model is little, in light weight, cost is low, simple in structure, be better than general electrothermal tube and heating wire.
Below in conjunction with description of drawings detailed structure of the present utility model.
Accompanying drawing is the schematic diagram of this lunch box heater, (2) are the box body of lunch box heater among the figure, (1) is lid, (4) be the metallic heat radiating plate that is complementary with box body (2) inner bottom part, the lower surface of heat sink (4) is close to upper insulation plate (5), below the lower surface coating one deck Electric radiant Heating Film (6) of upper insulation plate (5), Electric radiant Heating Film (6) is lower insulation plate (7).Its following complementary space of metallic heat radiating plate (4) is alumina silicate fibre thermal insulation board (8).The supply socket of this lunch box heater (3) design is at the end wall of box body (2) bottom.During use, the lunch box that fills food places on the metallic heat radiating plate.
Claims (2)
1, a kind of lunch box heater comprises box body (2), lid (1).The bottom that it is characterized in that box body (2), design has the heat sink (4) that is complementary with box body (2) bottom interior wall, upper insulation plate (5) is arranged below the heat sink (4), and the lower surface of upper insulation plate (5) is coated with Electric radiant Heating Film (6), lower insulation plate (7) is arranged below the Electric radiant Heating Film (6).All the other following space segments of heat sink (4) are thermal insulation board (8), and supply socket (3) is located at the end wall bottom of box body (2).
