Description

Nonflame is from hot tableware

Technical field

The present invention relates to a kind of daily heater, relate to a kind of nonflame specifically from hot tableware.

Background technology

Great majority are applied to the method for portable heating and insulation at present, be to depend on as propane, butane, the gas that unleaded gas or its mix or the fuel of liquid, but the heating process of using liquid fuel and gaseous fuel often needs complicated high hot production mechanism, because it relates to the more work parts, will be difficult to parts place under repair and replacement like this, maintenance and the expense of changing also can be higher, though if adopt the heater meeting of fuel rod and fuel flat board both economical, but shortcoming is that the firing rate of food is slower, is exactly that the flame that produced of most of portable cooking system needs windproof barrier guarantee that flame does not extinguish in addition; Exist a kind of heating lunch box of forming by lunch box body and heater now on the market, utilize the coal briquette burning that food is heated, play the effect that within a certain period of time lunch box is incubated, heater is provided with fan, the speed that can regulate the air inlet air intake is controlled the speed of coal briquette burning, when but shortcoming is to use be the heating means that to use kindling material to light, use inconvenience and dangerous; The constant temperature electrical heating lunch box that also has a kind of PTC of utilization semiconductive ceramic electric heating element, temperature in lunch box rises to 110 when spending, can reduce electrical power automatically, make lunch box carry out temperature constant state, avoid sticking with paste meal and save electric energy, but weak point is to have under the situation of power supply and could use, environment for use is subjected to bigger restriction, can not use in the open air; Moreover be exactly a kind ofly to form by outer box, lid, fixed support, rotation handle, inner bag and heating agent etc. from heating lunch box, leave the space outside in the middle of box and the inner bag, be provided with removable water bag and calcium oxide heating bag outside in the space of box and inner bag, shortcoming is to carry and open inconvenience, and unreliable.

Summary of the invention

Need naked light in order to overcome the traditional heating device, security is low, and also or need power supply, limitation is big, moreover problem such as volume is big, weight is big, heat time heating time is long, be inconvenient to carry, and the invention provides a kind of nonflame from hot tableware.

The technical scheme that the utility model is adopted for achieving the above object is: nonflame comprises outer box, inner box from hot tableware, and inner box is nested in the outer box, leaves the space between described inner box bottom and the outer box bottom, in the described space heat packs is housed.

Design has the exhaust passage between described outer box and the inner box sidewall.

Described inner box is provided with lid.

Described lid is provided with buckle, and buckle is buckled on the outer box, and described lid inboard is provided with sealing joint strip.

Described outer box outside is with protective cover.

Advantage of the present invention is simple in structure, and volume is little, in light weight, easy to carry, and heat time heating time is short, and convenient the unlatching and operation, need not naked light and just can heat, and also need not electricity consumption, is applicable to various environment, and low price in the time of safe and reliable is used wide model.

Wherein: 1, outer box 2, inner box 3, lid 4, protective cover 5, heat packs 6, buckle 7, exhaust passage.

The specific embodiment

Nonflame comprises outer box 1, inner box 2 from hot tableware as Figure 1-3, and inner box 2 is nested in the outer box 1, leaves the space between inner box 2 bottoms and outer box 1 bottom, and heat packs 5 is housed in the space; Between outer box 1 and inner box 2 sidewalls design have exhaust passage 7, the angle of exhaust passage 7 be 2.5 spend to 3.5 the degree; The polyethylene or the LDPE material of porous adopted in the external packing of heat packs 5; Inner box 2 is provided with lid 3; Lid 3 is provided with buckle 6, and buckle is buckled on the outer box 1, and lid 3 inboards are provided with the sealing joint strip (not shown); Outer box 1 outside is with protective cover 4; The material of inner box 2 is a heat transfer type stainless steel material; Outer box 1 used material is food-grade PP.

Nonflame not only can heat food from hot tableware, and can keep surpassing one hour higher temperature in the container that uses stainless steel and sealing lid, and it can also be before food heats, serve as a leakproof, anti-overflow device afterwards; The effect of one of the part of this device inner box is to be used to place the food of needs heating, and inner box can most of stable being put among the outer box, also has enough spaces to be placed as one-time heating bag and water that inner box provides heat bottom the simultaneously outer box; Outer box is bigger slightly than inner box dimensionally, guarantees that like this steam can infiltrate from inside and outside box junction when the bottom heating produces a large amount of steam; In the lid with seal washer, the lid outside four limit symmetric positions have four be used for locking inner box and outside the snap close of box, be locked in the lunch box that forms an integral body together like this and just guaranteed the maintenance of safety and heat to the full extent; Heat packs is put in the bottom of outer box, pour the outer box of putting into heat packs into surveying measured water, just can make the two that chemical reaction takes place rapidly, produce a large amount of heats, temperature in lunch box or the cup is risen rapidly, depend on the size of heat packs and pour what of the water yield into that finally temperature that can reach and outside weather, environment and the kind etc. of putting into food have relation but add the water effect; The external packing of heat packs is to be made by a kind of material of porous, and heating material is wrapped in inside.External packing is polyethylene/LDPE paper, make water can penetrate wherein, chemical reaction fully takes place, and inner heat packs composition can not infiltrate yet, inner box is to be made by resistant to elevated temperatures stainless steel material, and outer box is made by food-grade PP material, and food-grade PP is the food-grade polypropylene plastics, few stripping harmful substance under normal condition and the high-temperature condition; Inner box is to be used for placing the food that needs heating or water, outer box is the heat packs that is used for placing porous, heat packs and water reaction discharge heat, inner box is positioned in the outer box, heat packs is activated in the outer box needs the food and the water that heat in the heat heating inner box that the back generates, and the lid of sealing has effectively been preserved heat to the full extent.

Concrete operations at first are placed on heat packs 5 outer box 1, and outwards add an amount of water in the box, outside the inner box 2 that will fill food in advance is placed in the box 1, the material of inner box is the stainless steel material that readily conducts heat, then lid 3 is covered on the inner box 2, lid 3 is provided with sealing joint strip and buckle 6, sealing joint strip is used for sealing inner box, buckle is buckled on the outer box, heat packs 5 and water reaction after 30 seconds, begin to produce steam, the angle of inner box 2 and outer box 1 sidewall design is that oozing out of steam created passage, is edible after 20 minutes.
