Abstract

The utility model which provides a portable charge type heating insulator for the food can be used on the occasion without the energy source such as the alternating current, and the food can be heated and insulated. The utility model comprises a container, the cap of the container, a heating barrel, a heat-insulating layer, a housing, a heat-insulating cap and a battery box. The rechargeable battery such as a nickel-cadmium battery and a storage battery are adopted as the energy source, the container is composed of two independent containers comprising an upper container and a lower container, and the food of two species can be simultaneously stored.

Description

Portable charge type heating insulator for food

The utility model relates to a kind of warmer, relates in particular to a kind of portable food heating warmer with heating function.

Present food heating warmer, basically can be divided into two classes: a class is without any thermal source, as incubation canteen, thermos cup etc., be double-decker, between container inner wall and outer wall, put insulation material, be incubated, not only heat-insulating property is poor for it, and can not cold food be heated.Another kind of is as the energy with 220 volts of alternating currents, heat by heater members, as electric heating mess tin etc., its shortcoming is to need 220 volts of AC powers, just can not use this heating warmer as the user of workman, student or the workplace AC-less power of outwork.

Another shortcoming that existing food heat-insulation device exists is to have only a container, can not deposit two kinds of different types of food.

The purpose of this utility model is to provide a kind of portable rechargeable-type food heating warmer power supply, that can use in power free place that self has.

Another purpose of the present utility model is to provide a kind of portable rechargeable-type food heating warmer that can deposit two kinds of different types of food simultaneously.

Food heating and heat-insulating of the present utility model, comprise container, container cover, be positioned at the outer cartridge heater of container, be positioned at cartridge heater outer heat-insulation layer, shell and insulation cover, it is characterized in that also comprising a battery case, with battery as power supply, adopt chargeable nickel-cadmium cell or battery, the heating wire on cartridge heater is connected with power sourced electric by power switch.

Use food heating warmer of the present utility model, can not only the food of heat be incubated, also can cold food be heated in power free place.

Fig. 1 is the cutaway view of an embodiment of warmer of the present utility model;

Fig. 2 is the cutaway view of another embodiment of warmer of the present utility model;

Fig. 3 is the cutaway view of another embodiment of warmer of the present utility model;

Fig. 4 is the cutaway view of another embodiment of warmer of the present utility model.

Embodiment of the present utility model is described below with reference to the accompanying drawings.

As shown in Figure 1, this rechargeable food heating warmer comprises the container 1 of store food, and container cover 2 is arranged on the container 1, makes container 1 sealing, prevents that the food of depositing from pouring out.Outside the container 1 cartridge heater 3 is arranged, be wound with heating wire (not drawing among the figure) on the cartridge heater 3, after the heating wire energising, can heat the food in the container 1, cartridge heater 3 can adopt aluminium, stainless steel or PC plastics with certain heat conductivility to make.Between shell 4 and cartridge heater 3 heat-insulation layer 5 is arranged, heat-insulation layer 5 can reduce in the container 1 and the heat exchange of external environment, for reducing the weight of whole warmer, adopts PS foamed plastics or PU Foamex in the present embodiment.The effect of enclosing cover 6 is identical with heat-insulation layer 5, also for reducing in the container 1 and the heat exchange of external environment, therefore also adopts the material with heat-proof quality, also adopts PS foamed plastics or PU Foamex in the present embodiment.

As shown in Figure 1, battery case 7 is positioned at the bottom of food heating warmer, and is electrically connected with heating wire on cartridge heater 3, middle serial connection power switch 8, and battery case lid 9 is positioned at battery case 7 one sides.Power supply of the present utility model adopts chargeable nickel-cadmium cell or battery.

Fig. 2 shows another embodiment of the present utility model.This embodiment is similar to the embodiment shown in Fig. 1, its difference is that container 1 is divided into upper container 1a and following container 1b, upper container 1a and following container 1b respectively have a container cover 2a and a 2b, can deposit the different food of two kinds of types, for example meal and dish etc. simultaneously like this in a food heating warmer.

Embodiment shown in Figure 2 is that with another difference of embodiment shown in Figure 1 the position of battery case 7 is different, and among the embodiment of Fig. 2, battery case 7 is positioned at a side of shell 4, and the top of battery case 7 is a lid 9.

Fig. 3 shows another embodiment of the present utility model.This embodiment is similar to the embodiment shown in Fig. 2, and its difference is down that container 1b does not have container cover, and warp equates with following container 1b mouth internal diameter outside the bottom of upper container 1a, and both can tight connectings.

Fig. 4 shows another embodiment of the present utility model.Among this embodiment, battery case 7 separates with warmer, and battery case 7 is electrically connected by the heating wire on lead 10, plug 11, socket 12 and the cartridge heater 3.Remaining structure is identical with embodiment shown in Figure 1.

Through test, according to the food heating warmer that the utility model is made, the heating through 4 hours can and remain on about 60 ℃ the heating of the meal in the warmer.
