Electric control principle of the present utility model is:

(1) utilize liquid level sensor that the liquid level signal of measuring is converted to the signal of telecommunication and give controller, thereby controller is made judgement control water valve according to the signal of sending here.

(2) by the temperature of temperature sensor measurement water, water temperature signal is become the signal of telecommunication give controller, thereby controller is controlled the electric current control water temperature of heating tube again according to the signal that receives; When low temperature, the evolution of heat of controller control heater constantly raises water temperature; When temperature surpassed setting value (100 ℃), controller can be cut off the electricity supply automatically; When liquid level was lower than setting value, controller can be cut off the electricity supply automatically.

(3) when the people fetches water, infrared sensor is issued controller with signal, sends instruction by controller, and the magnetic valve of opening cold water magneticvalve delivery port 7 or hot water electromagnetic valve'sdelivery port 8 automatically discharges water.

The good effect of a kind of water dispenser with infrared inductor control of the utility model:

Utilize liquid level sensor, button be set, infrared inductor controls the water level of water dispenser, regulate the water temperature of heat water valve, automatically induction feedwater, automatically induction switching-off, prevent dry combustion method, thereby had electronically controlled function, and has the advantage that control is flexible, easy to use and reliability is high.
