Description

The multifunctional cold and heat crisper

The utility model belongs to the tableware class, and it is specifically related to a kind of structure of novel Fresh-keeping mess tin.

The food food that driver and conductor on field man, migrant person, tourism and the train carries the rotten problem that addles can occur in summer, the problem that has hot meal or steamed rice winter, more than these problems can not solve with most economical method always, a kind of automobile-used semiconductor cold and warm box is arranged on automobile at present, make low-temperature receiver with conductor refrigeration, its advantage is behind the power supply on its connection automobile, can make the temperature inside the box reduce by 10-20 ℃ than environment temperature, shortcoming is that the temperature inside the box also improves when environment temperature is high, food still can go bad, and this cold and warm box involves great expense; Be unsuitable for different voltage; Semiconductor element poor insulation property when non-transformer, the very fast rising of the temperature inside the box does not have preservation.Can not steaming food when reverse use, more can not make water boiled, therefore limited its scope of application.A kind of directly-heated type plastics electric heating mess tin is arranged in the prior art, energy heated food after its energising, but can not cold storing and fresh-keeping food in summer.Know the lunch box that insulation, heating, refrigeration, fresh-keeping function can be integrated in one beyond example still according to investigations.

The purpose of this utility model provides a kind of lunch box simple in structure, and it can be with food cold storing and fresh-keeping within a certain period of time, and decapacitation carries that food is outer can also to have beverage, can heat food when needing, and can adapt to different voltages.

By as above design, the multifunctional cold and heat crisper that this programme provided include one by at the bottom of the box, the seal box that constitutes of lid, its concrete feature is: its seal box is the sealing crisper that has heat insulation layer, its inside also has the lunch box of a splendid attire food, in the sealing crisper, be provided with heating, between lunch box and sealing crisper, the mezzanine space that can hold water arranged.

At the bottom of the box of the sealing crisper in this programme, lid all is polypropylene plastics crust hollow structure, is full of the heat insulation layer of rigid polyurethane foamed plastic in hollow sandwich.(2) are five box bodys of a rectangle at the bottom of the box of sealing crisper, the continuous recess that one rectangle is arranged in the middle of the upper port plane of box body, four support protrusion are arranged on the bottom surface of box body inside, lateral surface at the bottom of box has the recessed plug of a joining power, plug is connecting of sealing with the side of box body, plug still keeps the form of plug in box body inside, heating in order to the various different voltage class of pegging graft, the hinge seat that a locking bail is respectively arranged on two lateral surfaces of box body minor face, locking bail is a rectangle hook with dual limit, the mid portion of hook has a long wheel, is provided with limber rubber weather strip in groove suitable for reading at the bottom of the box.Its lid (1) is to have the crochet that bends up around rectangular to match with four sides at the bottom of the rectangular box, the projection that two triangular-sections parallel with minor face are arranged at the nearly minor face of the upper surface of lid place, its chucking that matches with the roller of the locking bail of fastening, inside at the sealing crisper also has a lunch box (4), lunch box is five box bodys of a rectangular thin-wall, the wide flange all around that outside vertical continuous is arranged suitable for reading of box body, around flange, also has the little crochet of vertically turning up continuously, little crochet that should be continuous all around matches with continuous recess suitable for reading at the bottom of the sealing crisper box, little crochet is just in time held on the sealing strip among the groove, and simultaneously the bottom surface of lunch box just in time contacts with four support protrusion at the bottom of the sealing crisper box.

When using its band meal summer, the lunch box of food can being packed into, in the sealing crisper, can put into about 2 liters of beverage or water, lunch box is seated in puts into refrigerator in the crisper its beverage is freezed, take out crisper when going out, build lid and with the locking bail fastening, because the sealing crisper is to have heat-insulating property preferably, therefore the specific heat of liquid in the box can not melt greatly soon, can play the preservation that keeps low temperature.Under 36 ℃ of situations of environment temperature, keep in the lunch box 0～20 ℃ can reach 30 hours through test, 1.5～2 liters drinkable water or beverage are arranged simultaneously, drank in enough one day.The sky used and did not have the power supply situation spring and autumn, can in crisper, inject 15～2 liters of boiling water after, put into the lunch box of splendid attire food, build lid, food and boiling water all have 40--60 ℃ of moderate moisture after 30 minutes.In addition during spring and autumn, 1.5 liters 100 ℃ the food of packing in lunch box can be incubated more than 40 ℃ in 6 hours.Under the winter low temperature situation, can connect power supply, this programme is furnished with the heating of various voltage class, as the 48V of automobile with 6V, 13V, 14V train, the family expenses civil power is 220V, can make the food heating after the work of directly-heated type heating, all right steamed rice, can be with the metal grating steamed wheaten foods thing of open-work without lunch box, so its function is many and easy to use.

Adopt this programme can embody following superiority: 1. it is simple in structure, be suitable for China's actual conditions and in 1 year the four seasons can use; 2. it can preserve that food never degenerates and suitable beverage can also be provided; 3. can adapt to various power supplys, adaptability is widely arranged, the person's that still goes out good tool also has certain use value at home; 4. summer and refrigerator adapted, spring and autumn, winter and power supply or boiling water adapted, performance is good, easy to operate; 5. simple in structure, volume capacity is moderate, and cost is not high, is convenient to promote the use of.
