Steam generator and its descaling control method, device and electrical appliance

Abstract

The invention discloses a steam generator, a descaling control method and device for the steam generator and an electric appliance. The descaling control method includes the following steps that a water pump of a steam generator is controlled to stop supply water, the steam generator is heated to the preset temperature, the first preset time is maintained, and therefore the steam generator enters a dry burning state; and the water pump is controlled to be started within the second preset time, the saturated steam pressure in the steam generator reaches the preset value so that water scale in the steam generator can be flushed out. By means of the method, the water scale is flushed and removed through pulse steam, concentration of the water scale in the steam generator can be prevented, the heating efficiency of the steam generator is affected, and meanwhile the phenomenon that precipitation of harmful components happens due to the fact that a chemical acid descaling agent corrodes the steam generator, and the human health is threatened can be avoided.

Description

technical field [0001] The invention relates to the technical field of steam generators, in particular to a steam generator descaling control device, a steam generator descaling control method, 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 (such as bacterial residues, grease, etc.), 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. For example, the food cooked by the steam generator may not reach the required temperature, affecting food safety. [0003] In related technologies, some acids or chemical substances such as citric ac...

Problems solved by technology

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

For example, the food cooked by the steam generator may not reach the required temperature, affecting food safety

[0003] In related technologies, some acids or chemical substances such as citric acid, acetic acid, slow-release descaling tablets, and descaling agents are basically used to dissolve the scale on the inner wall. However, if things go on like this, the coating of the steam generator will fall off, thereby cause Al 3+ (Aluminum ion) precipitation, endangering human health

In order to efficiently and healthily clean the scale of the steam generator, physical descaling methods such as ultrasonic vibration method, electromagnetic method or electrostatic field method are also used in related technologies. Poor descaling and low reliability and stability
