Abstract

The utility model relates to a heat insulation outer pot and cooking inner pot assembly; a platform is provided on the bottom of an inner bladder of the heat insulation outer pot; the height of the platform is more than 1.5mm, and the area of the platform is less than one half of the area of the bottom of the inner bladder; a PTC electrothermal part is arranged in the platform. The utility model provides an energy saving pot which can boil and braise food.

Description

A kind of energy-conservation pot

The utility model is a kind of energy-conservation pot, particularly a kind of by being incubated outer pot and cooking interior pot and form, one height is arranged more than 1.5 millimeters at the bottom of the inner bag of its insulation outer pot, top area is in the raised platform of inner bag floor space below half, PTC heating core parts are housed in its platform, can finish the energy-conservation pot of the safety of boiling the task of stewing.

Known, thermos-cooker is a kind of energy-conservation pot of being made up of pot in insulation outer pot and the culinary art.The insulation outer pot divides pot body and pot cover two parts, and its pot body generally is made up of shell, heat-insulation layer and inner bag, and heat-insulation layer generally uses the very high polyurethane foam plastics of coefficient of heat insulation.Pot is made with metal or potlery tile in the culinary art, and bore is less relatively, the insulation outer pot the inside of can packing into.When using thermos-cooker, pot and being put on the stove fire heats in the culinary art of earlier food being packed into, treats food after boiling a period of time, and pot is put insulation outer pot the inside in will cook again, the heat continuation smoldering that utilizes food to put aside when heating.The energy-saving effect of thermos-cooker is fine.But thermos-cooker constantly descends because of kettle temperature, can't finish the tasks such as stewed of boiling.

Known, finish the stewed task of boiling, food must be placed on the interior heating of pot and make it constantly to roll this hydrolysate stripping of rolling heat food being produced.But, the food of shutting the pot the inside of pot cover is heated to and roll, but not overflow outside the pot, acquire a certain degree of difficulty.

Known, PTC semiconductive ceramic thermo electric material is a kind of posistor material.The thermal efficiency of this material is very high, and can limit temperature automatically, is not reaching before the Curie-point temperature of its setting, and its firing rate is very fast, in case near and reach Curie-point temperature, material will slow down even stop heating.This Curie-point temperature can be set in 50 ℃ to certain temperature spot in 350 ℃ of intervals through the technology adjustment.The PTC thermo electric material generally is assembled into the heating core parts and uses.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, the material flames of anger requires lowly to supply voltage, and fault rate is low.

The purpose of this utility model provides a kind of energy-conservation pot of finishing the safety of boiling the task of stewing.

Task of the present utility model is finished like this: manufacturing can be furnished with pot cover and the culinary art in the pot, by shell, heat-insulation layer and inner bag are formed the insulation outer pot of its pot body, a height is arranged more than 1.5 millimeters at the bottom of its inner bag, top area is in the raised platform of inner bag floor space below half, Curie-point temperature is housed more than 110 ℃ below 320 ℃ in the platform, operating power is at the PTC heating core parts below 390 watts more than 15 watts, below the heating core parts thermal insulation barriers can be housed, connect heating core parts and power line, and power switch can be installed, indicator lamp, parts such as timer.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.On outer pot of the present utility model or the pot cover O-ring seal can be housed.

When using the utility model, can pour food and water in culinary art pot, pot is put the insulation outer pot in will cooking again, shuts pot cover and connects power supply.At this moment, the heat that PTC heating core parts send will import pot in the culinary art into by platform, and formation localized hyperthermia in the bottom of a pan is boiling in culinary art, and the full pot of Convective Heating is finished the stewed task of boiling.When empty pot of energising occurring, PTC heating core parts energy volitional check heating guarantees safety.

The utility model utilizes PTC heating core parts to limit temperature automatically and regulates power automatically, guaranteed the stability of heat supply: utilize at the bottom of the inner bag platform area less and difference in height arranged, only support is lived the part in the bottom of a pan in the culinary art, make the heat that imports pot in the culinary art into be limited at one than the zonule, form hot-spot and hot upwelling, this hot upwelling both can make food roll in pot, can not cause food to overflow again.The utility model uses PTC heating core parts to do thermal source, and security is fine.

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 of the present utility model

With reference to Fig. 1, Fig. 2, present embodiment be by fireless cooker body [1], and pot [3] is formed in heat preservation cooker lid [2] and the culinary art, and its fireless cooker body [1] is by stainless steel casing [4], polyurethane foam plastics heat-insulation layer [5], and stainless steel inner container [6] and plastic bottom cover [7] are formed.Stainless steel casing [4] and stainless steel inner container [6] be contact site [8] up and down, and [9] are welded seal all.Heat preservation cooker lid [2] is equipped with O-ring seal [10] and links to each other with fireless cooker body [1] by hinge element [11].

As figure, stainless steel inner container [6] is directly barrel-shaped, 200 millimeters of diameters, the circular tower shape platform [12] of 5.8 millimeters of one height is arranged at inner bag [6] bottom, 70 millimeters of platform [12] top diameters, 230 ℃ of one cover Curie-point temperatures are installed in the platform [12], the PTC heating core parts [13] that operating power is 60 watts, as figure, heating core parts [13] are pressed in platform [12] by two ends with the fixing press strip [15] of screw [14], an expanded perlite thermal insulation board [16] are arranged below the heating core parts [13], and heating core parts [13] are connected with external power line [17], at last plastic bottom cover [7] is fixed on the stainless steel casing [4], finishes present embodiment.

When using present embodiment, with food and the water pot [3] in the culinary art of packing into, pot [3] put fireless cooker body [1] in will cook again, cover heat preservation cooker lid [2] and connect power supply.At this moment, the heat that heating core parts [13] send will form hot-spot and convection current in table top than the zonule in platform [12] import culinary art into pot [3], drive food and roll together.
