AI Technical Summary

Technical Problem

During the water replenishment process of existing ice makers, the sensitivity of the probe is reduced due to the accumulation of water impurities and water surface fluctuations, which affects the accuracy and stability of water replenishment.

Method used

The system incorporates a TDS water quality detection unit and a dual water level detection unit. By detecting the TDS values ​​and water level signals of the makeup water tank and the working water tank, the main control unit controls the water pump to perform water replenishment actions based on the signals, filtering out instantaneous abnormal signals, and ensuring that water replenishment is performed when the water quality is qualified and the water level is sufficient.

Benefits of technology

It improves the stability of water replenishment control, avoids accidental or insufficient water replenishment caused by impurity accumulation and water level fluctuations, and extends the service life of the ice maker.
