Problems solved by technology

Among them, the method of coating the surface of the heating pipe with a hydrophobic material can only reduce the scaling of the heating pipe, but cannot reduce the hardness of the water and improve the water quality.
The silicon-phosphorus crystal method is a chemical method. Adding additional chemical substances to the water will not only affect the health of the body, but also the silicon-phosphorus crystal drug tank or filter element is difficult to integrate with the electric water heater, requiring additional installation, which takes up space and is not beautiful

Embodiment 1

[0034] This embodiment proposes the first kind of electric water heater, such as Figure 1 to Figure 3 As shown, the electric water heater includes an inner container, an electric heating tube 1 , a flange 2 for installing the electric heating tube 1 and a built-in electrode 3 . In this embodiment, the built-in electrode 3 is installed inside the liner and arranged close to the electric heating tube 1 . Preferably, the electric heating tube 1 is a U-shaped heating tube.

[0035] The electric water heater also includes a positive and negative control circuit connected between the positive electrode and the negative electrode of the built-in electrode 3 for controlling the polarity exchange of the positive and negative electrodes of each electrode, and the positive and negative control circuit is connected with the control panel. The positive and negative control circuit can control the positive electrode and the negative electrode of the built-in electrode 3 to exchange polari...

Embodiment 2

[0051] This embodiment proposes a second type of electric water heater, which includes a built-in electrode 3, wherein the structure of the built-in electrode 3 is the same as the structure of the built-in electrode described in Embodiment 1, and the description is omitted here.

[0052] The electric water heater of this embodiment differs from the electric water heater described in Embodiment 1 in that: the installation position of the built-in electrode 3 in this embodiment is different relative to the electric heating tube 1 .

[0053] In this embodiment, specifically, as Figure 4 to Figure 6 As shown, the built-in electrode 3 is installed on the flange 2 and located inside the electric heating tube 1, that is to say, the cylindrical positive electrode layer 31 and the cylindrical negative electrode layer 32 of the built-in electrode 3 are located on the U-shaped electric heating tube 1 In the space between the two straight tubes on the inside. A spacer layer 4 is disposed ...

Embodiment 3

[0055] This embodiment proposes a third type of electric water heater, which includes a built-in electrode 3, wherein the structure of the built-in electrode 3 is the same as that of the built-in electrode described in Embodiment 1, and the description is omitted here.

[0056] The electric water heater of this embodiment differs from the electric water heater described in Embodiment 1 in that: the installation position of the built-in electrode 3 in this embodiment is different relative to the electric heating tube 1 .

[0057] In this embodiment, specifically, as Figure 7 As shown, the built-in electrode 3 is installed at the bottom of the liner, and the built-in electrode 3 is arranged near the heating end of the electric heating tube 1 and perpendicular to the electric heating tube 1 .

Abstract

The invention provides an electric water heater and relates to the technical field of electric water heaters. The electric water heater comprises an inner container, an electric heating pipe and a flange plate used for installing the electric heating pipe. The electric water heater also comprises a built-in electrode which is installed in the inner container and close to the electric heating pipe. The built-in electrode is used for removing scale, so that the scale-removing effect of the electric water heater is greatly improved, the hardness of water is reduced and the quality of bath water is improved.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to an electric water heater with a descaling function. Background technique [0002] After the electric water heater is used for a period of time, the surface of the heating tube in the inner tank is prone to scale, which leads to a decrease in heat transfer efficiency and greatly shortens the service life of the heating tube. [0003] At present, there are two main methods to avoid fouling of heating tubes of electric water heaters: one method is to coat the surface of heating tubes with hydrophobic materials to reduce scale adhesion; the other method is to add silicon-phosphorus crystal medicine tanks or The filter element can reduce the reactivity of calcium and magnesium ions, so as to achieve the purpose of scale inhibition. Among them, the method of coating the surface of the heating pipe with a hydrophobic material can only reduce the fouling of the heating pi...
