Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
It will the technical scheme of the embodiment of the invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
Preferred embodiment
The present embodiment proposes a kind of electric heater, and as shown in Figures 1 to 5, which includes liner 1, water inlet pipe 2
With external electrode 7.In the present embodiment, the outside of liner 1 is arranged in external electrode 7, and external electrode 7 includes electrode water inlet pipe 73
With electrode outlet pipe 74, electrode water inlet pipe 73 is connected to running water pipe, and electrode outlet pipe 74 is connected to the water inlet pipe 2 of liner 1.
Electric heater further include external electrode 7 positive electrode and negative electrode between connect for controlling positive and negative electrode pole
Property the positive and negative control circuit exchanged, positive and negative control circuit connect with control panel.Positive and negative control circuit can control external electrode 7
Positive electrode and negative electrode are according to scheduled time and/or frequency progress polarity exchange, and the commutation cycle of positive and negative control circuit can
It is set according to particular condition in use by control panel, the electrical property of positive and negative electrode is replaced in timing, to effectively prevent adding in liner
The deposition of heat pipe scale.
In the present embodiment, specifically, as shown in Figure 4 and Figure 5, external electrode 7 include positioned at external package casing 5,
The cylindrical positive electrode 71 and cylindrical negative electrode 72, cylindrical positive electrode 71 and circle that 5 inside of package casing is set and is arranged
