Abstract

The utility model relates to anti-scale electric heating pipe which is especially suitable for the technique of a heating device with an immersed type heating method. The anti-scale electric heating pipe comprises an electric heating element, an insulating and heat conducting layer coated outside the electric heating element, an outer casing coated outside the insulating and heat conducting layer, and an anti-scale layer coated on the outer surface of the outer casing. Scale can not be deposited on the electric heating pipe, the heat efficiency is high, and the energy can be saved by 10 % to 30%.

Description

Anti-incrustation scale electric heating tube

The utility model belongs to the technical field of the heater that is specially adapted for the immersion heating.

Our electric kettle or electric hot water bottle of using now, in use for some time, on electric heating tube, all have the very firm incrustation scale of one deck, and along with the growth of service time, incrustation scale is long-pending more thick more, the serious transmission that hinders heat, the heat efficiency is descended, sometimes it is quick-fried strong electric heating tube also can to occur, and will wash incrustation scale, is again quite to bother with difficult.

The purpose of this utility model provides a kind of not scaling, and the high anti-incrustation scale electric heating tube of the heat efficiency.

This anti-incrustation scale electric heating tube comprises electrothermal piece, wraps in the insulating heat-conductive layer of electrothermal piece outside, wraps in the shell on the insulating heat-conductive layer, and be coated with the antiscale layer on the outer surface of shell.

Owing on the outer surface of shell, be coated with the antiscale layer, make that the incrustation scale that forms adheres to less than heating tube when feedwater is heated on, thereby make it not scaling, thereby make heat efficiency height.

Accompanying drawing shows embodiment of the present utility model, wherein:

Figure 1 shows that the front view of anti-incrustation scale electric heating tube;

Figure 2 shows that along the cutaway view of A-A line shown in Figure 1.

Anti-incrustation scale electric heating tube as shown in the figure, comprise electrothermal piece (1), and electrothermal piece (1) is a heating wire, wrap in the outside magnesium oxide insulating heat-conductive layer (2) of electrothermal piece (1), wrap in the tubular shell (3) on the insulating heat-conductive layer (2), be coated in the fluosilicic material antiscale layer (4) on shell (3) outer surface, and antiscale layer (4) is anti-scale crust.

In use, the anti-scale crust on the outer surface of outer cover stops incrustation scale attached on the electrothermal tube, thereby makes not scaling of electric heating tube, has both made and has tied some incrustation scales a little, also can come off automatically, so heat efficiency height.

Claims

1, a kind of anti-incrustation scale electric heating tube comprises electrothermal piece (1), wraps in the outside insulating heat-conductive layer (2) of electrothermal piece (1), wraps in the shell (3) on the insulating heat-conductive layer (2), it is characterized in that being coated with on the outer surface of shell (2) antiscale layer (4).

2, anti-incrustation scale electric heating tube according to claim 1 is characterized in that electrothermal piece (1) is a heating wire.

3, anti-incrustation scale electric heating tube according to claim 1 is characterized in that antiscale layer (4) is anti-scale crust.
