Water quality detection method and system and electric steam box with water quality detection function

Abstract

The invention discloses a water quality detection method and system and an electric steam box with a water quality detection function. The method comprises the following steps of: providing at least two electrodes and immersing the electrodes into to-be-detected water to obtain a to-be-detected capacitance difference value; determining the water hardness of the to-be-detected water according to the to-be-detected capacitance difference value and a linear mapping relationship; providing sampling water with at least two kinds of water hardness; respectively immersing the at least two electrodesinto the sampling water; respectively acquiring a sampling capacitance difference value between the at least two electrodes; and obtaining the linear mapping relationship between the sampling capacitance difference value and the water hardness. Capacitance difference values between sampled water with different water hardness and electrodes of the sampled water are sampled, a linear mapping relationship between the water hardness and the capacitance difference value is fitted through calibration, the to-be-detected capacitance difference value of the to-be-detected water is acquired through theelectrodes, and the water hardness of the to-be-detected water is evaluated through the linear mapping relationship and the to-be-detected capacitance difference value, thereby achieving the purposeof water hardness detection.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a water quality detection method, a system and an electric steamer with a water quality detection function. Background technique [0002] With the popularization of household appliances, more and more appliances need to heat water, such as electric steamer, when the hardness of water quality is too high, the generator of the steamer is easy to scale, which will affect the thermal efficiency and shorten the service life. In practical application , it is not easy to quantitatively measure and evaluate the hardness of the water quality, and the excessively hard water quality may lead to scaling of electrical appliances, affecting the normal use of electrical appliances. Contents of the invention [0003] The object of the present invention is to provide a water quality detection method, system and electric steamer with water quality detection function, which solves...
