The water after the pressure equalizing treatment is discharged into the first box 36 of the water tank 20 through the mesh structure 54 of the pressure equalizing device 44 to avoid water accumulation in the first water receiving pan 22. As a result, the drainage is not smooth, and the humid air is attracted by the fan 18 and flows along the air flow channel to the air outlet and is discharged to the external space to achieve the humidification effect.

In the dehumidification mode, the humidification unit 14 and its spray device do not work. The external air enters the air flow channel through the air inlet and then flows to the evaporator of the heat exchange unit 16. The liquid refrigerant medium in the evaporator vaporizes when encountering hot air. And absorb the heat of the air to dehumidify it. At this time, part of the wet steam will condense into water on the hydrophilic fins. After the water gathers, it will fall into the second water receiving tray 24 under the action of gravity. The second water receiving tray The second drainage hole 50 of 24 and the slanted downward extension 62 can enable the water in the second water receiving tray 24 to be quickly discharged to avoid the water in the second water receiving tray 24 causing poor drainage. The water discharged from the hole 50 enters the pressure equalizing device 44 for pressure equalizing treatment. The water after pressure equalizing treatment is discharged to the first box 36 of the water tank 20 through the mesh structure 54 of the pressure equalizing device 44. The dehumidified air passes through the air. The flow channel flows from the air outlet to the external space to achieve the dehumidification effect.
