Description

A kind of Smoldering container

The utility model is a kind of Smoldering container, particularly a kind ofly in the pot or bucket of insulation PTC semiconductive ceramic heating core parts is installed, can promote and keep certain pot warm, simple structure, energy-conservation, safe Smoldering container.

Known, thermos-cooker is a kind of cooker of being made up of fireless cooker body, interior pot and heat preservation cooker lid.The fireless cooker body is generally by shell.Insulation interlayer and inner bag constitute, and its shell generally is made of several parts, and its insulation interlayer generally uses the very high polyurethane foam plastics of coefficient of heat insulation, the more use metal material of its inner bag.The manufacture craft of fireless cooker body generally is earlier shell and inner bag to be assembled into hollow body, polyurethane foam plastics is injected wherein foaming again and finishes.Foamed plastics also plays a part pot body each several part is bonded together simultaneously.Pot is generally made with stainless steel or potlery tile material in the thermos-cooker, and is removable.Heat preservation cooker lid generally is an individual components, utilizes axis to be fitted to the fireless cooker body.When using thermos-cooker, generally be that pot and being put on the stove fire heated in food was packed into, treat that food after boiling a period of time, puts interior pot in the fireless cooker body into again, utilize heat that food put aside in the continuous smoldering of heat insulation environment relaying.The major advantage of thermos-cooker is energy-conservation.But there is following defective in thermos-cooker: the one, inconvenient, must be earlier before the smoldering with food boiling a period of time more longways, generally also to return after the smoldering and boil.The 2nd, the pot temperature constantly reduces during smoldering, influence culinary art effect, and this defective is obvious especially when environment is cold.

Known, portable type heat insulating bucket and thermos-cooker are structurally similar, and just volume is less and do not have an interior pot.

Known, heating is placed on the inner heating of heat-insulated container, can reduce heat and run off, reach energy-conservation purpose.

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 bucker.Insulating barrier.Compositions such as electrode PTC heating sheet, outward appearance is the waterproof PTC heating core parts of flat, and its electric wire passes outside the parts by the double hollow bolt or the hollow pipe that connect usefulness done.Hollow bolt or pipe generally are positioned at the bottom surface or the side of heating core parts.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 simple structure, and is energy-conservation, and safety can promote and keep the warm Smoldering container of certain pot.

The purpose of this utility model reaches like this: manufacturing can be equipped with the pot or the bucket of the insulation of insulation cover, and the pot of insulation or bucket are by shell.Insulation interlayer and metal inner tube constitute, in the pot or bucket of insulation, on the metal inner tube, Curie-point temperature is installed more than 60 ℃ below 280 ℃, operating power is less than 800 watts PTC heating core parts, installation can be to utilize the hollow bolt of PTC heating core parts to pass metal inner tube to connect, and also can be by other securing member PTC heating core parts to be connected with metal inner tube, connects heating core parts and power line.PTC heating core parts of the present utility model can have more than two groups or two groups, and its Curie-point temperature can be different with power.The top margin of the utility model metal inner tube along top and can extend edge, also can encase shell top margin edge along the top margin that can translate into shell.The utility model can be equipped with power switch, electrical socket, indicator lamp, timer, control circuit board etc.

When using the utility model, can adopt will need to improve or will keep the food of the certain pot temperature container of packing into, put into again fireless cooker or barrel, connect the mode of power supply again and finish.

The utility model adopts PTC heating core parts is installed on built-in structure in the fireless cooker bucket, and its heat runs off few, and heating property is good, has reached to promote and keep certain pot temperature and purpose of energy saving.This built-in structure is easy for installation, can also utilize the interval of metal inner tube, and heater and insulation interlayer are separated, and improves security.Pot of the present utility model is knocked over the limit structure and can be prevented effectively that sealing or steam enter the insulation interlayer, have improved insulation and security performance.

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

Fig. 1 is the schematic diagram of a kind of embodiment of the present utility model

Fig. 2 is the cross-sectional schematic of a kind of embodiment pot body of the present utility model

With reference to Fig. 1, present embodiment is by fireless cooker body [1], and heat preservation cooker lid [3] and interior pot [4] three parts are formed, and in its fireless cooker body [1] PTC semiconductive ceramic heating core parts [2] are installed.With reference to Fig. 2, fireless cooker body [1] is made of stainless steel outer boiler hull [5], plastic bottom cover [6], insulation interlayer [9] and stainless steel inner container [8].Platform towards indent [7] is arranged at outer boiler hull [5] bottom, in the middle of the platform porose [10].Stainless steel inner container [8] is a diameter and highly all little than outer boiler hull [5] pot, and the top of inner bag [8] is set with a plastics pot collar [11], in the middle of the bottom porose [12].Stainless steel outer boiler hull [5] is sleeved on stainless steel inner container [8], and hole [10] and hole [12] are aligned.Towards the middle polyurathamc plastics that inject of outer boiler hull [5] and inner bag [8], form insulation interlayer [9].With 130 ℃ of cover Curie-point temperatures, the PTC semiconductive ceramic heating core parts [2] that have bucker that peak power is 80 watts are installed in above the stainless steel inner container [8].Earlier a silica gel waterproof washer [13] is placed on the inner bag [8] during installation, the hollow bolt [14] with heating core parts [2] passes waterproof washer [13] and hole [10], 12[according to this again], finish connection with nut [15].External power line [17] is connected with heating core electric wire [16], sintered porous light ceramic is filled up the cavity [18] that forms after platform [7] indent, with screw plastic bottom cover [6] is connected in above the stainless steel outer boiler hull [5] again.

As shown in Figure 2, the top margin of fireless cooker body [1] is along being made of stainless steel inner container top margin [19], pot collar [11] and stainless steel outer boiler hull top margin [21], and the edge [20] of its stainless steel inner container top margin [19] is turnup inwardly, encases stainless steel outer boiler hull top margin [21].

When using present embodiment, can earlier the interior pot [4] that fills food be placed on and be heated to food on the stove fire and just seethe with excitement, interior pot [4] be moved put fireless cooker body [1] into again, cover pot cover [3], connect dispatch from foreign news agency again and get final product.
