Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
This electric-controlled box low temperature dehumidification device, it includes electric-controlled box 1, mainboard 2, temperature sensor 4, humidity sensor 5, exhaust blower 6 and air compressor 7, mainboard 2 it is fixed with in electric-controlled box 1, temperature sensor 4 and humidity sensor 5, the sidewall of electric-controlled box 1 is provided with exhaust blower 6, it is provided with air compressor 7 in the outside of electric-controlled box 1, the outlet side of air compressor 7 connects the supervisor 8 that gives vent to anger, the supervisor 8 that gives vent to anger is positioned at after electric-controlled box 1, it is parallel with out gas branch pipe 9 on supervisor 8 giving vent to anger, the stage casing going out gas branch pipe 9 is positioned at electric-controlled box 1, outside electric-controlled box 1, go out to be provided with on gas branch pipe 9 check valve 10 and electromagnetic valve 11, check valve 10 is near the outlet side going out gas branch pipe 9, electromagnetic valve 11 is near the inlet end going out gas branch pipe 9；And described temperature sensor 4, humidity sensor 5, exhaust blower 6, air compressor 7, electromagnetic valve 11 are all connected by circuit with mainboard 2.
Being provided with electric heating sheets 3 in described electric-controlled box 1, electric heating sheets 3 is connected by circuit with mainboard 2.
Integrated Intelligent dehumidifying devices such as present invention electromagnetic valve 11, check valve 10, exhaust blower 6, air compressor 7, temperature sensor 4, humidity sensor 5 and mainboard 2.Reach dehumidifying condition, the temperature and humidity data gathered by temperature sensor 4, humidity sensor 5, feed back on mainboard 2, Based Intelligent Control electromagnetic valve 11, exhaust blower 6 is opened, utilize the give vent to anger high temperature of supervisor 8 of air compressor 7 work to reduce the humidity in electric-controlled box, smoothly dampness is drained by exhaust blower 6, thus the moisture reduced in air causes short circuit because temperature low coagulation becomes water droplet to be attached to component surface.
Check valve 10 is set, it is ensured that air does not refluxes.
The present invention detects the temperature in electric-controlled box 1 and humidity condition by temperature sensor 4, humidity sensor 5, and determines whether moisture requirement by mainboard 2: (having dehumidification more than 70%, less than 50% without dehumidification).
If there being dehumidification, and the temperature in electric-controlled box 1 is more than or equal to 27 DEG C, directly opens exhaust blower 6, with outdoor ventilation, is drained by moisture, until electric-controlled box humidity is reduced to 50%, closes exhaust blower 6.
If the temperature in electric-controlled box 1 less than 27 DEG C, then judges air compressor 7 and is turned on or off state:
If a compressor is closed, then opening electric heating sheets 3 and heat, time delay opened exhaust blower 6 after 1 minute, with outdoor ventilation, was drained by moisture, until the humidity in electric-controlled box 1 is reduced to 50%, closed exhaust blower 6.
If b air compressor 7 is opened, then open electromagnetic valve 11, open exhaust blower 6, with outdoor ventilation, moisture is drained, until the humidity in electric-controlled box 1 is reduced to 50%, close electromagnetic valve 11,30 seconds pass exhaust blowers 6 of time delay.
If c is during dehumidifying, in electric heating sheets 3 and air compressor 7 handoff procedure, then exhaust blower 6 is held open state, only needs switching solenoid valve 11, electric heating sheets 3 can not dehumidify with air compressor 7 simultaneously.
