Embodiment 1

[0044] Embodiment 1: When operating in manual mode, the dehumidifier can be turned on by adding the button, and the dehumidifier can be stopped by the minus button;

Embodiment 2

[0045] Example 2: When the automatic mode is running, set the upper and lower limits of humidity through the setting button. When the ambient humidity detected by the dehumidifier is higher than the set upper limit, the dehumidifier will automatically turn on, and the humid air will be sucked into the dehumidifier through the fan In the process, the humid air in the air is condensed into water droplets through the joint action of the cooling fin 4, the heat sink 6 and the condensation fin 5, and is discharged from the distribution box through the drain pipe 8, completely solving the phenomenon of condensation in the distribution box; when detected When the ambient humidity is lower than the set lower limit, the dehumidifier will automatically shut down to ensure that the ambient humidity is within the range of the upper and lower limit set values.

[0046] The present invention adopts the matching structure of the dehumidifier body 1 and the control board 2, so that the dehumid...

Abstract

The invention discloses a dehumidifier for a tunnel distribution box, which comprises a dehumidifier body and a control panel, and the dehumidifier body comprises a shell, a refrigeration sheet, a condensation sheet, a cooling fin, a fan, a drainage pipe, a display screen, a plurality of control keys, a temperature and humidity sensor, an antenna and a power supply; the refrigeration sheet, the condensation sheet, the cooling sheet and the drainage pipe are all arranged in the shell, and the drainage pipe is arranged below the condensation sheet; and the control panel is arranged in the shelland comprises a single-chip microcomputer, a data acquisition module, a display module, a wireless module, a refrigeration sheet full-bridge control module, a key control module, a cooling fan controlmodule, a power supply module and a downloading module. According to the invention, humid air is sucked into the dehumidifier through the fan, the humid air in the air is condensed into water drops through the cooperation of the cooling fin, the refrigeration fin and the condensation fin, and then the water drops are discharged out of the distribution box through the drainage pipe, so that the condensation phenomenon in the distribution box is thoroughly solved.

Description

technical field [0001] The invention relates to a dehumidifier, in particular to a dehumidifier used in a tunnel distribution box. Background technique [0002] Condensation and dripping are prone to occur in the distribution box in the tunnel, which will cause the distribution box to rust and mold. The rust and mold of the distribution box are mostly caused by moisture. When moisture is found, measures should be taken to prevent moisture. Existing dehumidification methods include dehumidification by using dehumidifiers, heaters, and cement plugs, but these methods can only play a certain role in the dehumidification of distribution boxes, but the dehumidification effect is not ideal, because dehumidifiers are used to dehumidify them. The amount is limited, and the absorbed moisture is difficult to discharge; the heater can only reduce the relative humidity in the cabinet by not increasing the temperature in the cabinet, but does not reduce the water content in the air in t...
