Air is the basic reason that causes food spoilage, the food preserving box of prior art, the exchange that the general mode that adopts box body to seal is stopped the box body inner air and outer air, thereby reach the effect of food fresh-keeping, but itself have air in the box body, so the food resting period can not be long in the box, otherwise perishable.
Simultaneously, can not the food in the box being incubated of prior art food preserving box needs external heat source heating rear edible, but external heat source be sometimes because environmental limitations can not find, thereby limited its application; Though the existing lunch box that is provided with heater in the prior art, the lunch box fresh keeping property is poor, and is city's electrical heating, both dangerous, be subjected to the supply socket restricted number again, can not colony or away from the supply of civil power, moreover electric heating element is resistance wire, heats inhomogeneously, easily produces and burns a little.
The utility model content:
At the defective that prior art exists, the purpose of this utility model provides a kind of being heated evenly, the thermal efficiency height, and heat time heating time is short, energy consumption is low, food fresh-keeping, the food box that temperature retention time is long, applicability is strong, is beneficial to apply.
Solve the problems of the technologies described above and take following technical scheme to realize: novel heating fresh-keeping foodstuff box, comprise shell body and outer casing upper cover, be provided with also plate-rack and the heating inner bag of column distribution in the shell body, be provided with built-in power between plate-rack bottom and the shell body, be provided with first heater between heating inner bag bottom outside and the shell body, the inside of heating inner bag is provided with bottom it and fixedly connected stripe shape second heater of relative two sides difference, and first, second heater is connected with built-in power and/or external power source circuit respectively; Being separated by with second heater in the heating inner bag is distributed with two side by side and vacuumizes food container, and two sidewalls that vacuumize food container closely contact with second heater respectively.
The bottom inside face of described heating inner bag is provided with two ring grain type hot conductive pads corresponding with vacuumizing food container, and the center of the hot conductive pads of ring grain type protrudes from card, closely contacts with the bottom that vacuumizes food container.
Vacuumize the food container use that matches with vavuum pump, in be the negative pressure state storage food, vacuumize food container and constituted by vessel and the container cover that is interlocked with it, be provided with sealing ring between the two, container cover is provided with unidirectional air-stopping valve.
Be provided with the heat insulating reflecting layer between described first heater and the shell body, reduce the excess loss of heat energy, first heater is the Far-infrared Heating lamella.
Described second heater is by the stripe shape far-infrared heating film and cover on its outside metal-back and constitute.
Described shell body is provided with liquid crystal display and the control panel that is connected with built-in power and/or external power source circuit.
Fix by snap close between described shell body loam cake and the shell body, perhaps a side is fixed by rotating shaft, and opposite side is fixed by snap close relatively.
The beneficial effects of the utility model are:
1, sealing between shell body and the outer casing upper cover, form a confined space in the shell body, simultaneously, also is a confined space in the food container, and dual-seal is beneficial to the insulation, fresh-keeping of food long period.
2, vacuumize and be negative pressure state in the food container, boiling point reduces, and can heat the prepared food thing in the short time, reduces and uses electric energy consumption; Simultaneously, because this product has long heat insulation function, also saved the heating power consumption.
3, first, second heater heats vacuumizing food container bottom and sidepiece respectively, simultaneously, the heating inner bag is provided with the hot conductive pads of ring grain type, and the center of the hot conductive pads of ring grain type protrudes from card, it is closely contacted with the bottom that vacuumizes food container, be beneficial to the conduction of heat energy; This product by heating face is big, thermal efficiency height, and uniform heat distribution can not form and burn some energy-conserving and environment-protective.
4, the power supply that uses of the utility model is built-in power and/or external power source, is subjected to the power utilization environment effects limit low, is beneficial to and applies.
The utility model is small and exquisite, is easy to carry, and thermal efficiency height, good refreshing effect, real is intensive crowd and field work personnel's indispensable good merchantable brand.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
