Abstract
A semiconductor refrigerating device (7) is arranged on a box cover (5) of the multifunctional portable lunch box. The box body (1) is provided with an energy storage body (16), a heating device (13), a temperature control system (12) and a self-contained direct-current power supply. The lunch box not only has the functions of heating, heat preservation and refrigeration of an external alternating current power supply, but also has the functions of temperature control, energy storage, heat preservation and the like, and can charge a self-contained direct current power supply. Is suitable for the cooking and catering of the students in middle and primary schools, the working personnel who work continuously and the travelling personnel on business trip.
Description
The utility model relates to a kind of " multifunctional portable lunch box " of civil.
Common lunch box does not possess heat-insulating property, and general incubation canteen does not have the function of heating, refrigeration." the multifunctional portable lunch box " that we develop not only has heating, insulation and the refrigerating function of external AC power supply, but also has functions such as temperature control and accumulation of energy insulation.
The purpose of this utility model just provides a kind ofly has temperature controlled heating, insulation and refrigerating function, and the multifunctional lunch box that is convenient for carrying.Cooking table ware as the staff in numerous residents, student, the place of working continuously and out of town trip personnel etc.
The purpose of this utility model is achieved like this: " multifunctional portable lunch box " comprises lid (5), inner box (8) and box body (1).Be equipped with semiconductor cooling device (7) on the lid (5), be equipped with storage body (16), heater (13), temperature control system (12) on the box body (1) and provide dc source for oneself.Between lid (5) and the box body (1) inner box (8) is housed.Box body (1) is provided with and connects liquid bath (4) and leakage opening (2).Import at leakage opening (2) is equipped with filter (3).The heat energy that utilizes heater (13) when work storage body (16) to be held, the electric energy of perhaps providing dc source for oneself and being held can also be realized accumulation of energy heat insulation function of the present utility model.
Inside and outside shelter, when operation place or out of town trip, use by " multifunctional portable lunch box ", both can finish the heating (hotting plate) of food drinks such as recess snack, working lunch and beverage easily, cooking affairs such as insulation and refrigeration, can replace ordinary lunch-box again, as the food container of food drink.
Now in conjunction with the accompanying drawings, embodiment of the present utility model is described below:
Be equipped with semiconductor cooling device (7) on the lid (5).Between lid (5) and the box body (1) inner box (8) is housed.Between the bottom of box body (1) and bottom (15), storage body (16), heater (13), temperature control system (12) and thermal insulation packing layer (14) are housed respectively successively.This heater (13) can be far infrared heating system or other electric heating system.In the electric box (10) of box body (1) end control circuit is housed, provides dc source and power cord storage storehouse for oneself.Electric function switch and function demonstration thereof then are installed on the panel (11) of electric box.For preventing heating when (hotting plate), the liquid boiling in the inner box (8) overflows, and damages device, connects liquid bath (4) and leakage opening (2) in the design of the surrounding of box body (1), is equipped with filter (3) in the import department of leakage opening (2).Lid (5) is fastened on the box body (1) by bayonet socket, meanwhile, and by the connecting circuit of contact pair (9) conducting lid (5) with box body (1).Contact pair (9) can be designed to one with bayonet socket, also layout design separately.During operation, connect power supply by power line, select and the functional switch that closes (at this moment, corresponding function shows), this functional circuit is started working, and gradually the temperature of the food drink of splendid attire in the inner box (8) is remained between the temperature of the upper and lower limit that this function presets.Before the refrigerating function that comes into operation, then should open top cover (6) earlier, so that the abundant heat radiation of refrigerating plant.Provide the accessory power supply of dc source for oneself, be used for there be not the occasion of AC power, support heat insulation function work as heat insulation function.Under cooking or non-cooking state, utilize AC power, all can be to providing the dc source charging for oneself.The heat energy that utilizes heater (13) when work storage body (16) to be held, the electric energy of perhaps providing dc source for oneself and being held can also be realized accumulation of energy heat insulation function of the present utility model.
Claims (3)
1, a kind of civil " multifunctional portable lunch box ", comprise lid (5), inner box (8) and box body (1), it is characterized in that: be equipped with semiconductor cooling device (7) on the lid (5), be equipped with storage body (16), heater (13) and temperature control system (12) on the box body (1).
