Method and device for preventing electrochemical corrosion, steam generator and wash aid

Abstract

The present invention proposes a method and device for preventing electrochemical corrosion of a heater, a steam generator and a clothes care machine, the method is used in a clothes care machine, and the clothes care machine includes: a steam generator and a power module, The steam generator is used to generate steam, and the power supply module is used to provide protection current for the steam generator. The steam generator includes a heater. The method includes: installing a conductor on the steam generator, and the conductor is electrically insulated from the heater. The heater is electrically connected to the cathode of the power module, and the anode of the power module is electrically connected to the conductor, so that the conductor is in contact with the water in the steam generator to form a current loop to compensate for the electrons lost by the heater , to prevent the heater from losing electrons and being corroded. Through the technical solution, the electron migration that occurs when the metal undergoes electrochemical corrosion is effectively suppressed, thereby avoiding or weakening the occurrence of electrochemical corrosion of the heater.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a method for preventing electrochemical corrosion of a heater, a device for preventing electrochemical corrosion of a heater, a steam generator and a clothes care machine. Background technique [0002] At present, the working principle of the steam generator for clothing care products is to heat and evaporate water through a metal heater, and convert electrical energy into heat energy of water vapor. [0003] The heater material of clothing care products mainly contains active metals such as aluminum, iron, copper, etc., and there are no measures to prevent electrochemical corrosion. During the working process of the heater and the period when it stops working, the heater is in a humid environment for a long time, and a conductive water film is attached to the metal surface. The metal on the surface of the heater and its own impurities are likely to form m...

AI Technical Summary

Problems solved by technology

The above-mentioned anti-scaling measures cannot prevent the electrochemical corrosion of the heater

In the initial stage of use of this type of electrical appliances, the rust caused by electrochemical corrosion is often more serious than the scale left after water evaporation, and the service life will be seriously affected by the corrosion of the heater.
