Description

A kind of portable phase-transition heat-storage meal insulation bucket
Technical field
The present invention relates to heat preservation dinner flask field of containers, be specifically related to a kind of portable phase-transition heat-storage meal insulation bucket.
Background technology
Heat preservation dinner flask is generally the container that is added the food that vacuum layer or thermal insulation layer make by double glazing or stainless steel, and lid is arranged at top, seals tightly, and vacuum layer or thermal insulation layer can make to be contained in inner food and delay heat radiation, to reach the object of insulation.Heat preservation dinner flask develops from vacuum flask, and heat preservation principle is the same with vacuum flask.The propagation of heating power has three kinds of approach: radiation, convection current and transmission.In heat-preserving container, the inner bag of silver color can reflect radiation of heat, and the vacuum layer of ladle body or thermal insulation layer can be blocked hot transmission, and therefore heat preservation dinner flask can make the food in bucket keep within a certain period of time certain temperature, and user just can have hot meal very easily.But existing heat preservation dinner flask temperature retention time is short, in temperature retention time, the time of higher temperature length makes food because high temperature occurs that nutrient loss is more simultaneously, particularly the vitamin in vegetables etc. more easily runs off, as the nutriments such as the vitamin C in vegetables will be destroyed when water temperature exceedes 80 ℃, long-time high temperature can make its loss more, traditional heat preservation dinner flask usually makes food spoiled, nutrition reduces, and temperature retention time is short, how can and keep for a long time a barrel interior temperature, can keep again the fresh and nutriment of food, it is problem demanding prompt solution in heat preservation dinner flask application.
Heat preservation dinner flask is a lot of in the market, there is glass heat-insulating good-for-nothing, stainless steel heat preservation dinner flask and ceramic thermal insulation good-for-nothing, in order to increase good-for-nothing temperature retention time, take electrical heat tracing technology, as application number CN201320078396, a kind of heat preservation dinner flask is disclosed, comprise box body and lid, in box body, be provided with inner bag, between described inner bag and box body, be provided with a circle vacuum interlayer; At the bottom of box, lay electric heating tube, electric heating tube and battery, switch connect to form heater circuit; Battery is arranged on box body outer wall.Application number CN201220675814, discloses a kind of novel heat preservation dinner flask, and it is mainly comprised of stainless steel rice bucket cover and double-layer stainless steel good-for-nothing; Double-layer stainless steel good-for-nothing is comprised of good-for-nothing main body, heating of metal net and power pack; Heating of metal net is arranged in the interlayer of bottom of good-for-nothing main body, and power pack is arranged on the side of good-for-nothing main body, and the electric power connection line of heating of metal net is connected with the joint of power pack; Realize long-time insulation.These two technology all disclose the method that extends heat preservation dinner flask with electrical heating above, there is certain advance, but there is no the open technical scheme that extends holding temperature with phase-change material of yet not mentioning, be that they do not utilize the heat of food itself to carry out heating phase-change material, this thermal energy storage in phase-change material, when food temperature is low, by phase-change material heat release, to keep and to extend the technical characterictic of good-for-nothing temperature.
Summary of the invention
In order to extend the temperature retention time of heat preservation dinner flask and the initial high temperature of fast reducing heat preservation dinner flask, keep nutritional labeling and the taste of food, the invention provides a kind of portable phase-transition heat-storage meal insulation bucket.The technical scheme that the present invention takes for realizing its object: a kind of portable phase-transition heat-storage meal insulation bucket comprises: bung, threaded bung, put dish box, inner heat-insulating barrel, urceolus and heat-preserving container handle, it is characterized in that inner heat-insulating barrel, by heat-preserving container inwall, is placed in the phase-change material layers of barrel inner wall outside, the heat-insulation layer that is placed in phase-change material layers outside forms.Inner heat-insulating barrel outside has insulation urceolus, heat-preserving container handle to be installed on insulation urceolus.
Preferred inner heat-insulating barrel is triplex glass bucket, the inwall of inner heat-insulating barrel inner layer glass plates one deck silver mirror, between heat-preserving container internal layer and middle level glass, it is phase-change material layers, in phase-change material layers, fill certain phase-change material, between middle level glass and glass outer, it is heat-insulation layer, heat-insulation layer is vacuum layer, vacuum≤10 of vacuum layer -2pa, outwards conducts to block a barrel interior heat.
Preferred inner heat-insulating barrel is three layers of stainless steel cask, the inwall of inner heat-insulating barrel internal layer bucket wall plates one deck silver mirror, between heat-preserving container internal layer and middle level, it is phase-change material layers, in phase-change material layers, fill certain phase-change material, between middle level and skin, it is heat-insulation layer, heat-insulation layer is vacuum layer, vacuum≤10 of vacuum layer -2pa, outwards conducts to block a barrel interior heat, and this preferred version does not need urceolus, and heat-preserving container handle is directly installed on outer stainless top.
Preferred urceolus is stainless steel cask or Plastic Drum.
Preferably putting dish box is plastic casing, puts the seamless heat-preserving container inside that is positioned over of dish box.
The preferred dish box of putting is stainless steel box.
Preferred phase-transition heat-preserving material is dopen Nano aluminium paraffin, and phase-change material phase transition temperature is at 35-50 ℃.
Beneficial effect of the present invention:
Technical solution of the present invention has adopted phase-transition heat-storage technology, when heat-preserving container starts splendid attire food, high temperature food passes to heat phase-change material and stores rapidly, due to time lengthening, when food temperature will be lower than phase transition temperature, phase-change material generation states of matter changes, and discharges heat energy, maintains a barrel interior food temperature, the heating of this technological break-through traditional electrical extends temperature retention time, easy to use, efficient energy-saving, meets the development strategic objective of energy-saving and emission-reduction.
