Problems solved by technology
[0003] In order to overcome the related technology at least to a certain extent, the consumption of magnesium rods is judged according to the use time of the water heater. Due to the difference in water quality in various regions and the water temperature used by users, it will cause waste to replace the magnesium rods before they are consumed, or the magnesium rods have been replaced. Lately lead to corrosion of the water tank liner; determining the consumption of magnesium rods by measuring the electrical parameters on the electrochemical reaction circuit connecting the water tank liner and magnesium rods will cause the problem of high detection costs. This application provides a magnesium rod consumption detection method , devices and water heaters

The invention relates to a magnesium rod consumption detection method and device and a water heater. The magnesium rod consumption detection method comprises the steps of: obtaining water quality parameters of the water heater where a magnesium rod is located; acquiring working parameters of the water heater; and calculating the residual amount of the magnesium rod according to the water quality parameters and working parameters. The consumption of the magnesium rod in the water heater water tank can be accurately evaluated, a user is reminded to replace the magnesium rod in time, it is ensured that the water heater water tank is not corroded, and detection cost is not increased.
Description
technical field [0001] The application belongs to the technical field of water heaters, and in particular relates to a magnesium rod consumption detection method and device and a water heater. Background technique [0002] Air energy water heater tanks generally use electronic anodes or magnesium rods (magnesium anodes) for anti-corrosion. Electronic anodes are used for anti-corrosion and do not require after-sales maintenance, but the cost is relatively high. Magnesium rods are used for anticorrosion, and the cost is low, but after-sales maintenance is required. The anti-corrosion principle of magnesium rod (magnesium anode) is to rely on the consumption of active metal magnesium to ensure that the metal material of the tank liner, such as metal iron, will not be corroded. Therefore, once the magnesium rod of the water heater tank is consumed, it will lose the anti-corrosion effect of the tank liner. Generally speaking, the magnesium rods of the water tank need to be repl...
