Abstract
The utility model relates to an electric heating table plate taking a ceramic sheet of positive resistance coefficient as the heating element. The utility model comprises a base plate, an electric heating layer and a coating and is characterized in that the electric heating element in the electric heating layer is the ceramic sheet of positive resistance coefficient. The electric heating layer comprises the ceramic sheet of positive resistance coefficient, a mica sheet, a conductive copper sheet, a spring sheet, a uniform heating aluminium plate and a heat insulating interlayer. The utility model has the advantages of safe use, low electric consumption and long service life.
Description
The utility model relates to a kind of platen as office equipment, particularly electric heating platen.
Existing electric heating platen uses heating wire as heater element more, and electric conversion efficiency is low, and safety in utilization is relatively poor, in case the heating wire short circuit, fire hazardous.The positive resistance coefficient potsherd has its advantage as electric heating element, heat efficiency height not only, and also safe in utilization, along with temperature raises, resistance increases, and the effect of nature constant temperature is arranged, thereby be widely used in daily necessities.
It is the electric heating platen of electric heating element with the positive resistance coefficient potsherd that the purpose of this utility model provides a kind of.
Task of the present utility model is to realize like this.The utility model comprises base plate, electrothermal layer, coating, it is characterized in that: the electric heating element in the electrothermal layer is the positive resistance coefficient potsherd.
Fig. 1 is a cutaway view of the present utility model.
Now in conjunction with the accompanying drawings the utility model is further described.The utility model comprises base plate (1), electrothermal layer (2), coating (3), it is characterized in that: the electric heating element (4) in the electrothermal layer (2) is the positive resistance coefficient potsherd.Base plate (1) is plank or bakelite plate.Coating (3) is natural fabric or chemical ﹠ blended fabric.Electrothermal layer (2) comprises positive resistance coefficient potsherd (4), mica sheet (5), conductive copper sheet (6), spring leaf (7), even hot aluminium sheet (8), adiabatic insulation (9), and adiabatic insulation (9) can be asbestos or mineral wool.Coating (3) is bundled into one with electrothermal layer (2), base plate (1).Can be at this electric heating platen loam cake with glass table top (10), use peripheral cornerite (11) that both chuckings are become an electric heating platen that has a glass table top then.
The utility model power consumptive province, safe in utilization, and long service life.
Claims (2)
1, a kind of electric heating platen comprises base plate (1), electrothermal layer (2), coating (3), it is characterized in that: the electric heating element (4) in the electrothermal layer (2) is the positive resistance coefficient potsherd.
2, by the described electric heating platen of claim 1, it is characterized in that: electrothermal layer (2) comprises positive resistance coefficient potsherd (4), mica sheet (5), conductive copper sheet (6), spring leaf (7), even hot aluminium sheet (8), adiabatic insulation (9).
