A kind of heating chassis of electrical heating type household electrical appliance in the utility model, using the resistant to elevated temperatures glass plate of anticracking,
As the heating chassis of electric kettle, health-promotion kettle, one layer of heating film is sintered in the bottom surface of glass plate, heating film is evenly arranged, in electricity
During heating, glass plate is heated evenly, and heat transfer is uniformly and heating is fast；Be not in local temperature it is long-term it is too high caused by make
The problem of with short life, and the upper surface that glass chassis contacts with water will not separate out heavy metal, the boiling water heavy metal free burnt is dirty
Dye.
The utility model sinters one layer of heating film in glass plate bottom surface, before sintering, first with diamond dust by after feather plucking
By a face feather plucking of glass plate, heating film is sintered in the one side of feather plucking, because coating is different from the fusing point of glass plate, easily causes burning
It can not be merged well during knot, the utility model sinters heating film in the one side of feather plucking, adds glass plate and heating film
Contact area, heating film is bonded on the glass of feather plucking, increase adhesive force, avoid coating and come off at high operating temperatures,
Heating film expands after the heating, there is the shrink space of feather plucking, and the influence suffered by heating film is smaller.
Heating film is that the feather plucking bottom surface that glass plate is imprinted in the method for silk-screen up, or is manually pasted onto glass plate bottom surface,
The roasting upper feather plucking bottom surface of high temperature again, makes glass plate bottom surface preferably be fused together with heating mould；Add one layer in the bottom surface of heating film
Insulation film, insulation film is the silicon based aerogel of 1000 DEG C of high temperature resistant, or is the glass heat-insulating coating of 1100 DEG C of high temperature resistant, is passed through
The setting of insulation film, heat of the heating film in heating process is sent out is focused on glass plate, is delivered to glass plate upper surface
In heated liquid, reduce distributing for heat, heat utilization efficiency is higher, heats up water faster, saves the time of heating up water, saves electricity
Energy；Set stainless steel disk to separate in the bottom surface of insulation film, protect temperature controller and electric wire and other electron component, extend
Temperature controller and electric wire, the service life of other electron component.
