technical field

The utility model relates to the technical field of water heaters, in particular to an anode structure and a water heater.

Background technique

In life or industrial production, various water storage containers are often used, because the clean water prepared by the waterworks is not completely pure, and usually contains sediment, mineral ions, residual chlorine, different colors, dissolved oxygen, etc. Especially in the heating state, dirt and impurities are deposited in the water storage container. After long-term use, it is easy to cause corrosion of the water storage container, thereby affecting the performance of the water storage container and shortening the service life of the water storage container.

In water heaters, the inner tank of the water heater usually adopts the cathodic protection method of sacrificial anode, that is, the method of sacrificially sacrificing the anode rod with higher activity than the inner tank by electrochemical corrosion to protect the inner tank from corrosion. However, the anode rods in the existing water heaters are in direct and full contact with the water in the inner container. Since the activity of the anode rods is much higher than that of the carbon steel used as the base material of the inner wall of the inner container, the amount of the anode rods consumed in the occurrence of electrochemical corrosion It is far more than the amount required for inner tank corrosion, resulting in excessive waste of anode rods, shortening the service life of anode rods, increasing the frequency of replacing anode rods, and increasing the cost of use.

In addition, during the protection process, the anode rod gradually absorbs ions and impurities in the water to form insoluble matter, and the flowing water in the inner tank directly contacts the anode rod, and scours the insoluble matter on the anode rod to cause the insoluble matter to peel off and fall to the The bottom of the inner tank leads to the formation of an environment at the bottom of the inner tank that is prone to scale accumulation, which in turn accelerates the generation of scale in the inner tank.
