Abstract
The utility model relates to an electric heating pan, comprising a base and an electric heating pipe. The electric heating pipe is positioned in a silicon aluminum alloy heat conducting pan, the electric heating pipe and the heat conducting pan are cast and fixed into integration, the bottom of the heat conducting pan is fixedly connected with a steel supporting pan, the upper face of the heat conducting pan is a concave-arc face which is coated with an infrared radiating coating, and the bottom of the steel supporting pan is coated with a heat insulating coating. The electric heating pan has fast heating speed, small heat loss, high heat efficiency, no deformation and long service life.
Description
The utility model belongs to the special-purpose heater members of electric-heating cooking utensil, is used in particular for the heating of electric food warmer.
Present domestic a kind of electrothermal tube cast aluminium formula heating plate that has, this dish mechanical strength is low, and temperature distortion is big, and heating plate bottom undulate, area of dissipation is big, and thermal loss is many, also has a kind of composite shaping tubular type heating plate, this dish is a split-type structural, the heat transfer loss is big, and the heating plate bottom is undulate also, and area of dissipation is also big, thermal loss is many, so be restricted in application.
The purpose of this utility model just is the deficiency at prior art, provides a kind of mechanical strength height, distortion is little, firing rate is fast, the heat efficiency is high, the electric heating plate that the life-span is long.
Technical solution of the present utility model is: a kind of electric heating plate comprises base, electric heating tube.Electric heating tube is positioned at heat conducting disk, and is casting integrated fixing; The heat conducting disk bottom connects with steel tray.Be cancave cambered surface above the heat conducting disk, be fixedly connected with infrared radiating coating.The steel tray bottom is fixedly connected with thermal insulation coat.Heat conducting disk is casting integrated being fixedly connected or the bolt connection with connecting of steel tray.
According to technique scheme, electric heating tube and silicon-aluminum heat conducting disk are casting integrated, no intermediate link, and heat conduction is fast, and thermal loss is few.The invar tray bottom is straight shape, and its area of dissipation lacks than waveform, has reduced thermal loss.The coefficient of linear expansion of aluminium is bigger than steel, and the expansion of silicon-aluminum is subjected to the restriction of steel tray, and distortion alleviates, and heat-transfer area is stable, has prolonged useful life.Heating plate is cancave cambered surface, scribbles the far infrared radiation coating on it, and the bottom scribbles heat preserving and insulating material, has improved the heat efficiency of electric heating plate.
Accompanying drawing is a cross-sectional schematic of the present utility model.
In conjunction with the accompanying drawings, a kind of embodiment of the present utility model is described.A kind of electric heating plate comprises base, electric heating tube 1, and electric heating tube 1 is positioned at silicon-aluminum heat conducting disk 2, and is casting integrated fixing; Heat conducting disk 2 bottoms connect with steel tray 3.Above the heat conducting disk 2 is cancave cambered surface, is fixedly connected with infrared radiating coating 5.Steel tray 3 bottoms and thermal insulation coat 4 are fixedly connected.Heat conducting disk 2 is casting integrated with connecting of steel tray 3.
