Abstract
The invention discloses a TDS electrode circuit, comprising: a controller, a first resistor and a second resistor, one end of the first resistor is electrically connected to the first IO interface of the controller, and the other end is connected to the first The probe is electrically connected; one end of the second resistor is electrically connected to the second IO interface of the controller, and the other end is electrically connected to the second probe; the working state of the TDS electrode includes the scale prevention state and the detection state, when the TDS electrode is in the antiscaling state, the controller controls the first IO interface and the second IO interface to output a high level. The invention also discloses a water heater, a control method thereof and a readable storage medium. The invention keeps the cations in the total dissolved solids of water away from the TDS electrode, greatly reduces the content of cations near the TDS electrode, and further can significantly reduce the phenomenon of scaling on the surface of the TDS electrode, and improves the accuracy of TDS detection after the TDS electrode is used for a long time.
Description
TDS electrode circuit, water heater and control method thereof, and readable storage medium technical field The present invention relates to the technical field of water purification, in particular to a kind of TDS electrode circuit, water heater and control method thereof, can Read the storage medium. Background technique [0002] Electric water heaters have become essential appliances for families. Due to the influence of water quality, electric water heaters have been used for a long time. Scale will appear in the water heater, which will make the thermal conductivity of the electric water heater very poor, which will cause the heat transfer of the heating surface to deteriorate, thereby wasting fuel or electricity. The water quality is determined by the TDS (Total dissolved solids) of water. TDS refers to the total dissolved solids in 1 liter of water. How many milligrams of dissolved solids there are, measured in milligrams per liter (mg / L) or ppm. The higher th...
