Description

A kind of energy-conservation electrical heating double-layer stainless steel vacuum heat-preserving kettle
Technical field
A kind of heating and insulating utensils that uses electric energy particularly has the stainless steel electric heater unit of vacuum heat-insulating layer.
Background technology
Along with the raising of living standards of the people, electric kettle is universal day by day in family.Traditional electric kettle uses the simple combination of a heat-generating disc and single layer enclosure, and electric hot tray is made up of electrothermal tube, heat conduction aluminium dish, stainless steel disc.Because the electric hot tray volume causes thermal capacity big more greatly, again heat is delivered to the water in the kettle behind the electrothermal tube heating aluminium dish, and kettle body is single layer structure, in the electric hot tray heating, heat outwards distributes simultaneously in a large number, has reduced the utilization rate of electric energy.If the user wants boiled water is incubated for a long time simultaneously, a kind of method is that hot water is imported in the vacuum flask, and another kind of method is when detecting coolant-temperature gage in the kettle and being reduced to a certain degree, utilizes the heat-generating pipe of electric kettle to reheat, so circulation has caused a large amount of wastes of electric energy.
00240114.2 number utility model patent proposes " a kind of stainless steel electric heating thermal insulation kettle ", attenuating thermal loss, heating back intercept heat were distributed the function that improves the hot water thermal insulating duration when this electric kettle possessed heating.Because its bottom will be used for the device heater, therefore forming kettle body side is double-layer vacuum, and the bottom can only be the structure of individual layer, causes heat still can distribute in a large number from the bottom, and heat insulation effect is not good.
200420016838.1 number patent has proposed a kind of " Separate Type Three-layer Vacuum Electric Heating And Insulation Containers ", aluminium matter heat-generating disc is welded in the vacuum layer of inner bag bottom, the lead-in wire of heat-generating disc and the lead-in wire of temperature control element are all drawn from vacuum layer, because stainless steel kettle body need bear the high temperature more than 500 ℃ in vacuumizing plugging technology, high-temperature insulation seal member material properties and fusion plugging technology to charged lead-in wire and stainless steel kettle body lead-out wire require high, bad and the defective insulation situation of sealing shutoff appears easily, and this heat-generating disc and kettle body are welded as a whole, in case heat-generating pipe damages, this kettle body must be scrapped, because manufacturing cost high, make the large-scale industrial production of this scheme cannot.
02114858.9 disclose " a kind of electrothermal water boiling and heat maintainting bottle (kettle) ", the heat-generating disc of aluminium matter is fixed on the top of vacuum layer at the bottom of the kettle, kettle body bottom has metal tube to connect inner bag and back cover.Since added the metal tube that needs welding, the qualification rate of control weld seam, and preventing to vacuumize failure becomes the key that the kettle body is made.And metal tube and kettle body adopt the corner connection mode in this scheme, because stainless steel kettle body wall thickness is thinner, welding causes weld seam fusion burn-through and fine cracks to produce easily under the individual layer thin plate corner connection state, when vacuumizing,, cause this technical scheme can not transform productivity equally owing to the sealing failure causes the kettle body to be scrapped.Aluminium matter heat-generating disc in this scheme exists thermal capacity big equally, the slow problem of generating heat, and in addition, aluminium matter heat-generating disc can produce aluminium rust toxicity problem directly with the water contact.
Summary of the invention
The purpose of this utility model provides a kind of energy-conservation electrical heating double-layer stainless steel vacuum heat-preserving kettle, accomplishes easy making, easily welding between metal tube and the kettle body, heater thermal efficiency height, avirulence.
The utility model comprises by vacuumizing the kettle body that forms after the mutual seal welding of shell, inner bag and back cover, the double thermal insulation loam cake that constitutes by enclosing cover, inner cap, improvements are that the heavy hole central authorities of inner bag have the flange hole, there is the flange hole in back cover central authorities, metal tube interts in two flange holes and is welded on the flange in flange hole, the hollow screwed pipe of resistive film heat-generating disc passes metal tube, is equipped with silica gel sealing ring between resistive film heat-generating disc and the heavy hole, and nut is tightened on the hollow screwed pipe; Base is fixed on the hold-down nut of back cover below through screw, be equipped with in the base on control circuit board and socket, its panel temperature indicator and power knob are housed, be fixed with temperature sensor below the resistive film heat-generating disc, the resistive film heat-generating disc all passes through lead with temperature sensor and links to each other with control circuit board.The substrate of resistive film heat-generating disc is stainless steel or pottery.
Compared with the prior art, the utility model has following characteristics:
1, owing to the metal tube between inner bag and the back cover inserts in both flange holes; all the flange with the flange hole forms double-deck stack overlapping mode; this double-deck stack overlapping mode has increased the fusion thickness of material; metal burn through phenomenon in the time of can reducing welding; therefore improve product qualified rate; reduce kettle body manufacture difficulty and cost, can realize the scale production in enormous quantities.
2, in the heavy hole of inner bag, the resistive film heat-generating disc is installed, the substrate of heat-generating disc is stainless steel or ceramic making, upper surface of base plate contacts with water, and lower surface is printed with the resistive film of handling through insulation, when the resistive film heating power, because the substrate volume is little, thermal capacity is little, so substrate is rapidly heated, and is delivered to heat in the water fast, thereby reach thermal efficiency height, the purpose of saves energy.
3,, therefore do not influence water quality, sanitation and hygiene because the substrate of the resistive film heat-generating disc that contacts with water is stainless steel or pottery.
