Abstract

The utility model relates to a portable food thermal insulating box which comprises a food container (1), a cover (2) of the thermal insulating box, an anti-heat-radiation layer (3), a plastic foam thermal insulation layer (4), an air thermal insulation layer (5) and a casing (6) of the thermal insulating box. The utility model is characterized in that an oil box and an electric heater (7) thereof are arranged in the food thermal insulating box. The portable food thermal insulating box has the advantages of portability and good thermal insulating performance.

Description

Portable food thermal insulating box

The utility model is a kind of portable food insulation can.

Food heat-insulation is the thing that people often consider, people normally make the food heat-insulation goods with the glass refills of metal-coated membrane and the metal case of anti-collision now.But cost height, weight greatly, not portable, heat-insulating property is also undesirable.

In order to reduce cost, obtain good heat insulation effect simultaneously, people have invented the heat insulating products with the anti-thermal radiation layer of multilayer and thermal insulation layer, but since the food of insulation often temperature be lower than 100 ℃, the heat of storage is less, so cooling easily.

The purpose of this utility model provides a kind of portable food insulation can that is provided with fuel tank and electric heater thereof.It can will be located at by electric current, and the oil in the fuel tank is heated to more than 100 ℃ in the food insulation box, owing to increased the total heat that stores in the food insulation box, can make the food insulation box with same heat-insulating property obtain longer temperature retention time.Because the electric current of temperature booster is by being located at battery socket conducting on the insulation can, so after attaching plug was pulled up, insulation can be easy to carry.

The purpose of this utility model is achieved in that energized on the battery socket that at first attaching plug is inserted in food insulation box, oil in the fuel tank is heated to more than 100 ℃, pull up attaching plug then, open the insulation case lid, the food after the heating is put into food containers build.Because the total heat that heat source temperature improves, stores in the insulation can increases, and makes the corresponding prolongation of temperature retention time.

Contrast Fig. 1 and Fig. 2 are described in detail the utility model below.

Fig. 1 is the front view of a specific embodiment of the utility model.

Fig. 2 is the cutaway view of Fig. 1.

Fig. 3 is the birds-eye view of Fig. 1.

On figure: at first attaching plug is inserted in energized on the battery socket of food insulation box, the oil in the fuel tank 7 is heated to more than 100 ℃, pull up attaching plug then, open insulation case lid 2, the food after the heating is put into food containers 1 build.Because the total heat that stores in, the insulation can higher from the heat source temperature of fuel tank increases, and makes the corresponding prolongation of temperature retention time, and is easy to carry.

Claims

A kind of portable food insulation can, it comprises food containers, insulation case lid, anti-thermal radiation layer, plastic foam thermal insulation layer, air heat-insulation layer, insulation can shell, it is characterized in that being provided with in the food insulation box fuel tank and electric heater thereof.
