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

Abstract

The invention discloses an electric water heater, and relates to the technical field of electric water heaters. The electric water heater comprises an inner container and a water inlet pipe, and further comprises an external electrode. The external electrode is arranged outside the inner container and comprises an electrode water inlet pipe and an electrode water outlet pipe. The electrode water inlet pipe communicates with a tap water pipe. The electrode water outlet pipe communicates with the water inlet pipe of the inner container. According to the electric water heater provided by the invention, the external electrode is used for scale removing, the scale removing effect of the electric water heater is greatly improved, the hardness of water is reduced, and the quality of bathing 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...
