Abstract
This invention discloses a method for manufacturing vacuum heat isolation heat generating disks, which preprocesses a glass cover inserted with a metal connection ring on its rim when melting, an electrode through the wall and a pumping jet, a metal connection ring is pre-embedded in an AL electric heating disk in injection casting, after the lead out electrode of the Al disk is connected with the electrode through the glass cover, the Al disk is clutched with the glass cover and the connection rings of them are seal-welded, the air in it is pumped with a vacuum pump and the jet is melted to close it.
Description
Technical field
The present invention relates to electrothermal device, particularly a kind of manufacture method of electric heat-generating disc.
Background technology
Be widely applied to electric heat-generating disc in the domestic electric heating cooker, aluminium electric hot tray particularly, existing electric hot tray is that electrothermal tube is embedded in the mould, uses the aluminium die cast.Because electric hot tray has only top and cooker transmission of heat by contact, but following same heating, following heat distributes by the convection current of thermal radiation and air, causes heat utilization efficiency low.In addition, the drain pan of cooker can not be near excessively with electric hot tray, and pot waits in the utensil on as table, makes the height of cooker to reduce, and has limited the application of electric hot tray.
Summary of the invention
The object of the invention is to provide a kind of manufacture method of electric heat-generating disc of single face heating, to make high efficiency electric heat-generating disc.
The solution of the present invention is: a kind of manufacture method of vacuum heat insulating electric heating dish is the prefabricated cloche of elder generation, and cloche its bead when founding is embedded with the metal connecting ring, also is equipped with electrode on the wall, and leaves the mouth of bleeding; The aluminium electric hot tray is the built-in metal connecting ring when the die casting manufacture process, the extraction electrode of aluminium electric hot tray is with after the electrode that passes cloche is connected, aluminium electric hot tray and cloche fasten, with metal connecting ring on the aluminium electric hot tray and the metal connecting ring welded seal on the cloche, the air of getting rid of its inner chamber at last with vacuum pump, the molten mouth of bleeding that closes.
Advantage of the present invention is: because aluminium electric hot tray and cloche fasten, by metal connecting ring welded seal, wherein vacuumize, the heat below the aluminium electric hot tray passes through vacuum insulating, has prevented loss, has improved heat utilization efficiency.In addition, the cloche of bottom is owing to vacuum heat-insulation, and it is poor to add the upper glass conductivity of heat, and temperature is low can directly to be contacted with the cooker drain pan, can reduce the height of cooker, the convenient use.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Accompanying drawing is the structure cutaway view of electric heat-generating disc of the present invention.
Among the figure, 1 aluminium electric hot tray, the metal connecting ring on the 2 aluminium electric hot traies, the metal connecting ring on 3 cloches, 4 electrodes, 5 cloches, 6 mouths of bleeding.
Embodiment
The structure of the vacuum heat insulating electric heating dish of embodiment as shown in drawings, form by aluminium electric hot tray 1 and cloche 5 fastenings, all be embedded with metal connecting ring 2 and 3 in correspondence with each other on the aluminium electric hot tray and on the cloche, aluminium electric hot tray 1 is connected with 3 by metal connecting ring 2 with cloche 5, inner chamber is a vacuum chamber, and the extraction electrode of aluminium electric hot tray 1 is connected with the pre-buried electrode 4 that passes cloche 5.
Its manufacture method is: the prefabricated cloche of elder generation, the employing mould is made, cloche 5 its bead when founding is embedded with metal connecting ring 3, half is embedded in metal connecting ring 3 on the cloche in the cloche 5, second half exposes, and also is equipped with electrode 4 on the wall of cloche 5, and this metal connecting ring 3 and electrode 4 are embedded in die for molding during fabrication, to guarantee the air-tightness of interface, leave the mouth 6 of bleeding on the cloche 5.
Aluminium electric hot tray 1 is same built-in metal connecting ring 2 when the die casting manufacture process, half is embedded in metal connecting ring 2 on the aluminium electric hot tray in the aluminium electric hot tray 1, second half exposes, and the metal connecting ring 2 on the aluminium electric hot tray and the size of the metal connecting ring 3 on the cloche and position are in correspondence with each other.
The extraction electrode of aluminium electric hot tray 1 is with after the electrode 4 that passes cloche is connected, aluminium electric hot tray 1 and cloche 5 are fastened, metal connecting ring 2 on the aluminium electric hot tray and metal connecting ring 3 welded seals on the cloche are got rid of the air of its inner chamber at last with vacuum pump, the molten mouth 6 of bleeding that closes.
Claims (1)
- A kind of manufacture method of vacuum heat insulating electric heating dish is characterized in that: elder generation's prefabricated cloche (5), and cloche (5) its bead when founding is embedded with metal connecting ring (3), also is equipped with electrode (4) on the wall, and leaves the mouth of bleeding (6); Aluminium electric hot tray (1) is built-in metal connecting ring (2) when the die casting manufacture process, the extraction electrode of aluminium electric hot tray (1) is with after the electrode that passes cloche (4) is connected, aluminium electric hot tray (1) fastens with cloche (5), with metal connecting ring (2) on the aluminium electric hot tray and metal connecting ring (3) welded seal on the cloche, the air of getting rid of its inner chamber at last with vacuum pump, the molten mouth of bleeding (6) that closes.
