Specific embodiment

With reference to Fig. 1, the utility model provides a kind of water drain type electric cabinet dehumidifier, including casing 1, semiconductor cooler 2, Power module, fan 3, Monitoring and Controlling module 4 and drainage arrangement, Monitoring and Controlling module 4 respectively with power module, fan 3 and half Conductor refrigerator 2 is connected；Semiconductor cooler 2 includes Peltier 5, fin 6 and condensate film 7；Fin 6 and condensate film 7 It is individually fixed in the both sides of Peltier 5；The lower end of condensate film 7 is connected with drainage arrangement；The side of fin 6 is installed on fan 3.

Preferably, Monitoring and Controlling module 4 includes display, control keyboard, humidity detector and monitoring, alarming to the present embodiment Device；Control keyboard connection control display and monitoring alarm；Monitoring alarm connection control humidity detector.

Preferably, display is 4 Digital sum pipes to the present embodiment.The current data of display, and being capable of display control keyboard tune Data during section.

The present embodiment is preferred, the operating temperature range of humidity detector：- 20 DEG C to 80 DEG C；Humidity detector it is wet Degree detection range：40%RH to 99%RH.Within the range, the utility model being capable of normal work.

Preferably, monitoring alarm is provided with buzzer and radio communication alarm sounds device to the present embodiment.Can be with long distance From transmission data, alarm effect is better achieved.

Preferably, drainage arrangement includes drainpipe, tank 8 to the present embodiment；Pass through water between the lower end of condensate film 7 and drainpipe Groove 8 is connected.

Semiconductor cooling is doubted dehumidifying and is built upon on thermoelectric cooling basis, and the Peltier for using is by N-type and p-type two Plant the phenomenon that semiconductor converts electrical energy into heat energy.Cold doubtful dehumidifying is direct current by one or more pairs of N-types and P-type semiconductor reality Existing.In refrigeration mode, direct current flows to P-type semiconductor from N-type semiconductor.The temperature of thermoelectricity centering cold end reduces, and Heat is absorbed from environment, so as to reach the effect of cooling condensation.

Operation principle：Using damp-heat air to the cold can condensation operation principle, by electronic cooling method, in interiors of products Topical hypothermia's environment is created, and damp-heat air in cabinet is passed through the low-temperature region by fan 3, so that condensation is constantly produced, and The moisture for condensing is discharged outside electric cabinet by collection device, so as to reduce moisture in electric cabinet, reduces relative humidity, prevent electricity Cabinet produces dew condensation phenomenon.

Monitoring and Controlling module 4 has both of which：Respectively automatic mode and manual mode：

Automatic mode：After power on, dehumidifier enters automatic mode, and numeral method current environment humidity works as environment Humidity is more than operating valve value, and dehumidifier work, " dehumidifying " " fan 3 " " automatic " lamp is lighted.When ambient humidity is smaller than operating valve value When 10%, dehumidifier is stopped, and acquiescence humidity operating valve value is 65%.Such as need to change operating valve value, press " on " D score key changes Become threshold values, confirm that threshold values is preserved after actuation of keys.

Manual mode：Click " manual " key can force start dehumidifier, " dehumidifying " " manual " lamp is bright, after work 24 hours Into " automatic " pattern；Such as need to cancel manual mode, then by once " manual " button, dehumidifier exits manual mode, into certainly Dynamic model formula.

Break down：When fin 7 or fan 3 break down, malfunction indicator lamp is lighted, buzzer call, dehumidifier It is stopped.

Semiconductor cooler 2 is started working when energized reduces condenser temperature, in the presence of fan 3 actively By the humid air suction dehumidifying air channel of confined space, the steam in air condenses on the surface of condensate film 7 to be assembled, and instills water leg In 8, then cabinet is discharged by drainpipe.Fan 3 is used to cool down the radiating of semiconductor cooler 2, and makes air circulation, keeps removing Humidity uniformity in wet space.Switch cubicle normal-temp.-dehumidifying device can monitoring of environmental humidity automatically, when ambient humidity drops to During less than setting value, semiconductor cooler 2 is stopped, when ambient humidity is risen to more than setting value, semiconductor cooler 2 Restart work, to extend the service life of dehydrating unit and to save electric energy.
