Vapor generator, descaling control method and descaling control device thereof, and electric appliance

Abstract

The invention discloses a vapor generator, a descaling control method and a descaling control device thereof, and an electric appliance. The descaling control method comprises the following steps of real-time monitoring the temperature of the vapor generator during an operation process; generating a temperature cycling curve according to the temperature of the vapor generator during the operation process; comparing the temperature cycling curve and a preset temperature initial curve so as to obtain a comparative result; and judging whether the vapor generator needs to be controlled to be descaled or not according to the comparative result. According to the method, the temperature of the vapor generator during the operation process is real-time monitored, and whether the vapor generator needs to be descaled or not is accurately judged, so that the effectively intelligent descaling of the vapor generator can be realized.

Description

technical field [0001] The invention relates to the technical field of steam generators, in particular to a steam generator descaling control method, a steam generator descaling control device, a steam generator and an electrical appliance. Background technique [0002] During the long-term operation of the steam generator, due to the Ca in the water 2+ , Mg 2+ Waiting for some inorganic salts and other organic components will cause a layer of scale to form on the inner wall of the steam generator. The accumulation of scale to a certain extent will affect the heating efficiency of the steam generator, which in turn will affect the steam performance and service life of the steam generator, and will also bring certain safety hazards. Therefore, the scale in the steam generator needs to be cleaned regularly. [0003] In related technologies, it is usually judged whether the steam generator needs to be cleaned by monitoring the accumulated water consumption and the number of d...

Problems solved by technology

[0004] However, since the formation of scale in the steam generator is random and unpredictable, and is closely related to the environment and frequency of use of the steam generator, and because the water quality conditions in various regions vary greatly, the above-mentioned descaling control method for the steam generator It cannot be generalized, and can only be roughly estimated according to empirical values. It is very likely that when the steam generator needs to be descaled, the steam generator has already accumulated a lot of scale, which is prone to misjudgment, and the monitoring period of the above method is longer
