Abstract
The utility model relates to an electrically heating electric appliance using the graphite fibre as a heater, in particular to a ceramic electrically heating cooking electric device. In the utility model, the heater of the graphite fibre or the carbon fibre is cemented and sealed on the heating surface of the heating container of the electrically heating electric device; after the drying and the solidification at the lower temperature (lower than 250 DEG centigrade). The utility model has the advantages of simple manufacturing process, low cost, with the heat efficiency up to 86%, and is suitable for the manufacture of the integral type ceramic electrically heating electric device, such as an electric rice cooker, an electric chafing dish, an electric kettle, an electric tea cup, an electric heat preserving flask, etc.
Description
The utility model belongs to electric heating appliance, particularly the architecture advances of electric heating cooking utensil.
CN87215024U discloses a kind of design of making the integral type ceramic electric heating electrical equipment of heater with carbon fiber, this design has solved heating board and the ceramic heat container is the shortcoming that discrete causes bigger idle thermal loss, make material become direct heating by indirect, improved the heat efficiency of electric heating appliance greatly, but since this design be with carbon fiber heating body and function pottery topped and sintering in the ceramic heat container, carbon fiber exothermic part is oxidized when avoiding sintering, must adopt the non-oxidation sintering process, in the vacuum nitrogen sintering furnace, finish sintering process, thereby cost is higher, and technology is complicated.
The utility model is to avoid the shortcoming of above-mentioned prior art to propose the electric heating appliance of a kind of graphite fibre or carbon fiber exothermic part adhesion type, makes it not only keep the high advantage of the integral type electric heating appliance heat efficiency but also simplify technology, reduces cost.The utility model is specially adapted to make the ceramic electric heating cooking apparatus.
The utility model comprises heating container, graphite fibre heater or carbon fiber exothermic part, contact conductor etc., and its technical essential is can resistant to elevated temperatures fluid sealant bonding and be sealed in the heating surface of heating container graphite fibre heater or carbon fiber heating body and function.The matrix of said heating container can adopt pottery or glass or enamel material.For the electric heating cooking utensil, the bottom surface of its heating container is a heating surface usually, can form with refractory seals glue bond sealing and curing graphite fibre heater or carbon fiber exothermic part after lay the bottom surface of culinary art heating container.
The said refractory seals glue of the utility model can adopt silicates fluid sealant, organic silicon rubber class fluid sealant, polyimide fluid sealant, phenolic resins---and acrylonitrile-butadiene rubber class fluid sealant, polybenzimidazoles class fluid sealant etc., can adopt one-component or multicomponent mixture to carry out adhesive seal.
For increasing the heat resistance and the adhesive seal intensity of fluid sealant, used refractory seals glue can comprise an amount of oxide filler, and the content ratio of filler can account for 0～50%(percentage by weight of fluid sealant total amount).
Said oxide filler can be: the one pack system or the multicomponent mixture of brown iron oxide, alumina powder, silicon dioxide powder, calcium oxide powder, magnesia powder, titanium oxide powder, zirconia powder, lead oxide, barium monoxide, chromium oxide etc.
The utility model is because heater is to be bonded and sealed on heating container with high-temperature-resistant adhesive, only need to carry out baking and curing through lower temperature (below 250 ℃), the integral type electric heating appliance that this electric heating appliance is become have higher thermal efficient, thereby technology is simple, reduces the manufacturing cost of product greatly.Through test, the utility model safety durable, the heat efficiency can reach 86%, is particularly suitable for making integral type ceramic electric heating electrical equipment such as electric rice cooker, electric chafing dish, insulating pot, electric mug, electric vacuum flask, electric oven.
Fig. 1 is the utility model embodiment---the structure chart of ceramic electric cooker;
Fig. 2 is the wiring diagram of graphite fibre heater.
The making of this ceramic electric cooker is described in detail in detail below in conjunction with accompanying drawing, graphite fibre heating wire (2) is laid in bottom at ceramic electric cooker heating container (1), and two termination electrodes lead-in wire (3) fixed, contact conductor is drawn after can tying up with multiply thin copper wire and graphite fibre, use refractory seals glue (4) to be uniformly coated on the heating container bottom then, thickness can be 1～2mm, the complete topped sealing of graphite fibre well.Fluid sealant can be by 704 silicon rubber 80%, and brown iron oxide filler 20%(calculates by weight percentage) compound back a small amount of solvent (as dimethylbenzene) furnishing pasty state.The fluid sealant coating first air dry in back more than 10 hour, low-temperature bake is 2 hours then, and high temperature (200～250 ℃) baking is 2 hours again, makes sealing glue solidifying.Contact conductor (3) can be received temperature regulating device and the mains switch socket (6) in the outer casing base (5) of electric rice cooker.
Claims (5)
