Description

A kind of self-heating chafing dish

Technical field

The utility model relates to cooking appliance technical field, especially a kind of self-heating chafing dish.

Background technique

Many city office workers for daily noon, what was eaten and it is worried, most of office workers can select to eat hot gas in cafe Steaming food, however since the rhythm of life of office worker is fast, the dinner hour is shorter, and queuing time of having a meal is long, therefore Office worker is caused not have substantially the real time of having a rest at noon；Also there is part office worker to save and having a meal queuing time and cry outside Sell, however take out food be not when receiving edible it is very fresh, overeat to generate and be weary of sense；There are also sub-fraction workings Race can carry food, usually first with the lunch box with heating function or utilize microwave stove heating before eating, however due to included Food is all to be in advance burned, therefore the edible food heated again was not only unhealthy but also stale, can only gather as emergency The instant food of conjunction.

Meanwhile with the continuous improvement of people's living standards, the activity such as out on tours, field encampment is increasing, but eat Meal is at a great problem therein.Many people in out on tours or field encampment, can carry various instant noodles, bread, biscuit, The instant food such as beef, ship biscuit, can, fruit are compressed, although these foods are easy to carry, not needing heating can directly be eaten With bringing great convenience for the people of out on tours or field encampment, but eat these food to stomach and bad.

Currently, occur a kind of self-heating chafing dish, mainly multipurpose self-heating packet on the market, be mainly exactly utilize sodium carbonate, Roast diatomite, iron powder, aluminium powder, coke blacking, active carbon, salt, quick lime form one bag, be added water, temperature be up to 150 DEG C with On, vapor (steam) temperature is used to cooking up to 200 DEG C, is down to 100 DEG C within temperature hold-time long 20 minutes, is down to 60 after sixty minutes ℃.Fever process is without any pollution, without any security risk.Military food largely using this technology, in external self-heating packet Application be also very extensive.

Chinese Patent Application No. CN201710063071.X discloses a kind of convenient chafing dish, including self-heating meal box, it is described from Hot cutlery box includes outer box, compatible first layer inner box and second layer inner box and the oral area phase with the outer box with the outer box The box cover matched, the first layer inner box surround one to accommodate the of self-heating packet in the outer box and with the outer box One space, the second layer inner box surround one to accommodate in the first layer inner box and with the first layer inner box The second space of vacuum-packed chafing dish material packet and water packet, the interior bottom of the first layer inner box to the second layer inner box it is outer The distance of bottom is greater than the water packet and the superimposed height of chafing dish material packet, and the second layer inner box is to accommodate rice. But this apparatus structure is complicated, and in use, the high-temperature steam generated after self-heating Bao Jiashui be much directly from Outer box are discharged in the inner groovy of first layer inner box, have thus taken away many heats, and largely waste high-temperature steam.

Summary of the invention
