The work process of Infrared Humidifier is: the humidity sensor comprised in humidity sample circuit 210 gathers current environment humidity, and current environment humidity is inputted governor circuit 206.Governor circuit 206 includes control chip and peripheral circuit thereof.Peripheral circuit is used for receiving ambient humidity data, be filtered and analogue signal turn the operation such as digital signal after export to control chip.Current environment humidity data is compared with setting humidity threshold by control chip according to the algorithm set.When current environment humidity not up to sets humidity threshold, control signal is adjusted according to current environment humidity and the deviation value setting humidity threshold, as shown in Figure 2 b, in 0-T1 interval, current environment humidity differs relatively big with setting humidity thresholding, and the angle of flow of the silicon-controlled device in control chip output control signal is 180 degree, makes silicon-controlled device fully on, output is 220V to the alternating voltage of infrared lamp 203, and Infrared Humidifier adds moisture with maximum and runs.Meanwhile, the output voltage of the thyristor regulating volt circuit 202 detected by output detection circuit 207 is as the voltage input levels of feedback control loop, using the angle of flow of control chip output as reference value, the output voltage of regulation thyristor regulating volt circuit 202.And then, there is more water to flash to water vapour in tank 204, increase sharply ambient humidity.Detected the output voltage of described thyristor regulating volt circuit 202 by output detection circuit 207, and described output voltage is inputted to control chip.Control chip receives this output voltage and forms voltage close loop regulation, reaches stable output to the effect of the voltage of infrared lamp 203.
In humidification, compare current environment humidity and the deviation value setting humidity threshold in real time, in current environment humidity close to when setting humidity threshold, T1-T2 as described in Fig. 2 b is interval, current environment humidity is less with the deviation value setting humidity threshold, the angle of flow in the control signal of control chip output is gradually reduced, output is made to be gradually reduced to the virtual value of the alternating voltage of infrared lamp 203, thus be gradually reduced and add moisture, during until reaching to set humidity threshold (adding moisture to balance) with humidity number of dropouts, the voltage maintaining infrared lamp 203 two ends is constant.
