Intelligent liquid constant temperature control device and method

Abstract

The invention belongs to the technical field of temperature control, and particularly relates to an intelligent liquid constant temperature control device and method. The intelligent liquid constant temperature control device comprises a controller and a power supply module, wherein the input end of the controller is connected with a key input module and a temperature acquisition module; the output end of the controller is connected with a display module and an actuator control module; the key input module is used for acquiring target water temperature; the temperature acquisition module is used for acquiring real-time water temperature of a water mixing valve water outlet; the display module is used for displaying the real-time water temperature and the target water temperature; the controller is used for controlling a digital actuator to rotate or stop rotating; the actuator control module comprises the digital actuator arranged on the water mixing valve; and the digital actuator isused for controlling the openness of the water mixing valve, and constant temperature adjustment on the water temperature of the water mixing valve water outlet is realized. The openness of the watermixing valve is controlled through controlling the rotating angle of the digital actuator, the water temperature of the water mixing valve water outlet can be accurately adjusted, the structure is simple, the cost is low and the fault rate is low.

Description

technical field [0001] The invention belongs to the technical field of temperature control, and in particular relates to an intelligent liquid constant temperature control device and method. Background technique [0002] Existing thermostatic valve (thermostatic controller) mainly comprises five parts, is respectively: hot water inlet, cold water inlet, mixed water outlet, columnar piston, temperature-sensitive thermosensitive element. Its constant temperature principle is: a thermosensitive element is installed at the mixing outlet, and the characteristics of the thermosensitive element are used to push the spool in the valve body to move, and automatically adjust the opening of the cold and hot water inlet. When the temperature adjustment knob sets a certain temperature Finally, no matter how the inlet temperature and pressure of the cold and hot water change, the ratio of the cold and hot water entering the water outlet can change accordingly, so that the outlet water tem...

AI Technical Summary

Problems solved by technology

[0004] First, because the interior of the thermostatic faucet is very precise, the requirements for water quality are very high. If the water quality contains a lot of impurities, the thermostatic control valve may be blocked for a long time, which will affect the temperature control.

[0005] Second, the temperature sensing element of the thermostatic valve is high-purity paraffin, and the processing and assembly of the parts must be very precise.

[0006] Third, at present, most of the valve cores in China are made of paraffin wax, which is relatively slow to respond, especially the brand valve cores whose quality cannot be guaranteed are very prone to problems

[0007] Fourth, due to its precise structure, this kind of thermostatic valve is more expensive
