AI Technical Summary
Technical Problem
Existing technologies are unable to quickly cool boiling water to a suitable drinking temperature, and they also suffer from problems such as complex structure, high cost, and unstable temperature.
Method used
The system employs a dual heat exchanger system, including a high-efficiency first heat exchanger and an auxiliary second heat exchanger, combined with a parameter monitoring device and a flow control device. By monitoring liquid parameters, the flow direction is adjusted to achieve rapid cooling and temperature control.
Benefits of technology
It achieves rapid cooling of boiling water to 45-60℃, with precise temperature control, miniaturized device, low cost, avoidance of temperature fluctuations, and improved user experience.

Abstract
The application provides a liquid treatment device and a control method. The liquid treatment device comprises a liquid supply assembly, a heater, a first heat exchanger comprising two water circuits which exchange heat with each other, a second water circuit connected with the outlet of the heater, a parameter monitoring device for monitoring the parameters of the liquid treatment device, a shunt control device comprising an inlet connected with the outlet of the second water circuit, a first shunt branch and a second shunt branch, and used for controlling the on-off between the inlet and the two shunt branches according to the parameters of the parameter monitoring device, and a second heat exchanger used for heat exchanging the liquid flowing out of the second shunt branch. The heat exchange efficiency of the first heat exchanger is greater than that of the second heat exchanger, or the temperature drop of the second heat exchanger is smaller than that of the first heat exchanger. The scheme can perform heat exchange through the first heat exchanger when the heat exchange demand is small, and correct the outlet water temperature through the second heat exchanger when the heat exchange demand is large, so that the control precision of the outlet water temperature can be improved.
