Abstract

The invention discloses a corrosion preventing device and a water heater and belongs to the technical field of water heaters. Protecting metal and a cathode in the corrosion preventing device are located outside a water storing box and are in contact with an ionic solution; the protecting metal is connected with an auxiliary anode in the water storing box, and the cathode is connected with the water storing box; the auxiliary anode is in insulating connection with the water storing box; due to the fact that the protecting metal and the cathode are different in activity; under the effects of air, the cathode, the ionic solution and the protecting metal, the protecting metal is corroded, electrons are in lost and are provided for the water storing box through the cathode, and therefore migration of the electrons is formed, and the water storing box is protected; and besides, the protecting metal is arranged outside the water storing box, corrosion of the protecting metal cannot pollute water in the water storing box, the protecting metal is not in contact with high temperature water in the water storing box, self corrosion of the protecting metal is reduced, and the service life of the protecting metal is prolonged. The corrosion preventing device is adopted for the water heater, an external power source is not needed, more energy is saved, influences by power failure are avoided, and long-acting protecting can be formed for an inner container.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an anti-corrosion device and a water heater using the anti-corrosion device. Background technique [0002] In life or industrial production, various water storage containers are often used, because the clean water prepared by the water plant is not 100% pure, and usually contains sediment, mineral ions, residual chlorine, different colors, dissolved oxygen, etc. Especially in the heated state, dirt and impurities are deposited in the container. After long-term use, it is easy to cause corrosion of the container, affect the performance of the container, and shorten the service life. [0003] In water heaters, the corrosion of the inner tank is serious. At present, magnesium rods are used to control the corrosion of the inner tank. The magnesium rods are installed in the inner tank of the water heater to contact with water, and the residual substances after the reaction of th...
