Description

A kind of smoldering thermal-insulating bucket

The utility model is a kind of heat-preserving container, but particularly a kind ofly is made up of bottom heat conductivity heat-insulating bucket and split Electric heating seat, and PTC heating core parts are housed in the split Electric heating seat, uses and the heat-preserving container of the safety of the heated smoldering of convenient for washing.

Known, the portable type heat insulating bucket is a kind of cool-bag that mainly is made of shell, inner bag and heat-insulation layer, claims Thermal insulating carrying pot, vacuum flask, insulation meal basket or insulation ice bucket again, Vacuum insulation bottle.Its profile has shapes such as cylinder or circular tower, and ladle body has carrying handle, and volume is many to be raised to 4.6 liters 1.3.Heat-preserving container can use metal material to do shell and inner bag, and the top margin of its metal shell, inner bag can snap-in or welded together, and its heat-insulation layer is general to adopt the vacuum of finding time, or filling with insulation material such as foamed plastics, expanded perlite, fiber fragment material or the like.The portable type heat insulating bucket is at present more to be used for splendid attire by people and to carry warm food, and it can guarantee to keep uniform temperature in the regular hour, the food soup congee human consumption of heat promptly is provided within a certain period of time.But it can't be incubated for a long time, and its insulation situation is poorer when environment for use is cold.

Known, smoldering be a kind of under the insulation situation mode of cooking food, the more employing of people is put into food in the stainless-steel pan, stainless-steel pan is placed on to boil on the stove fire rises a period of time, and then it is put in the another fireless cooker body go, utilize the heat of putting aside to continue cooking food.The pot that people will adorn food usually is called interior pot or interior bucket.Smoldering needs two conditions, the one, cool-bag, the 2nd, heat.

Known, so-called PTC semiconductive ceramic thermo electric material is a kind of posistor material.This material not only thermal efficiency is very high, and can limit temperature automatically, is not reaching before the Curie-point temperature of its setting, and firing rate is very fast, in case near and reach Curie-point temperature, material will slow down even stop heating.The Curie-point temperature of PTC thermo electric material can be set on certain temperature spot through the technology adjustment, the restriction that made by semi-conducting material and industry, and this temperature spot can only be set between 50 ℃ to 350 ℃ scope.The PTC thermo electric material generally is assembled into the heating core parts, so that independent the use.Such as a kind of by the aluminium overcoat, insulation sleeve, the heating core parts that power-on and power-off pole piece, PTC thermo electric material are formed.Adopt not only simple structure of electrical equipment that PTC heating core parts do thermal source, thermal efficiency height, and safe especially---can limit temperature automatically, supply voltage be required low, fault rate is low.

The purpose of this utility model provides a kind of easy to use, and convenient for washing can heat the heat-preserving container of the safety of smoldering.

The purpose of this utility model reaches like this: manufacturing is made of metal shell, heat-insulation layer and metal inner tube, heat-preserving container and the split Electric heating seat that can be furnished with heat preservation cooker lid and interior bucket, the part of the metal inner tube of its heat-preserving container bottom or all with metal shell bottom applying formation thermal conductive zone, its split Electric heating seat mainly by Curie-point temperature less than 290 ℃, operating power PTC heating core parts less than 450 watts, base and power line constitute, its heating core parts can have outer cover, and outer cover can be metalwork or ceramic post sintering spare.Pit can be arranged at the metal shell bottom of the utility model heat-preserving container, touch the metal inner tube bottom at the bottom of the hole of pit and forms thermal conductive zone, on the heating core outer cover of split Electric heating seat the protuberance that cooperates with pit can be arranged.The outer cover of the utility model heating core can be two metalworks that clamp PTC heating core parts up and down.The utility model split Electric heating seat can be equipped with parts such as power switch, indicator lamp, timer, bimetallic temp-controlling element.

When using the utility model, needs are heated the food of smoldering and put in the heat-preserving container, again heat-preserving container is put into above the split Electric heating seat, connect the Electric heating seat power supply.Behind the PTC heating core parts heating power of Electric heating seat, its heat will import in the heat-preserving container through thermal conductive zone at the bottom of the heat-preserving container through the heating core outer cover again, the food in the heating smoldering thermal-insulating bucket.

The utility model utilizes the bottom thermal conductive zone of heat-preserving container, sends the heat that PTC heating core parts send to heat-preserving container, has reached the purpose of smoldering.The utility model is heat-preserving container and Electric heating seat design mix body structure, not only uses, convenient for washing, and can avoid Electric heating seat water inlet when washing, reached purpose of safety.

Below in conjunction with accompanying drawing the utility model is done concrete the introduction.
