Meanwhile, the controller 160 may be connected to the water level detecting unit 140 to receive position data of the float member 144.

In addition, the display unit 170 may be connected to the controller 160 to display the water level of the tank 130 so that the user may check the outside of the device.

Here, the position data of the float member 144 may be ON / OFF data indicating only the full water level of the water tank 130, as described above in the configuration that can detect the current water level of the water tank 130 in the displacement measuring sensor It may be position data of the measured float member 144.

On the other hand, in the dehumidifying apparatus 100 according to an embodiment of the present invention, when the water tank 130 is at full water level, the float member 144 is positioned at the highest rising height, and the controller 160 is the water tank on the display unit 170. The full water level of 130 may be displayed.

However, when the condensed water dropped on the upper surface of the float member 144 in the full water level state of the water tank 130 as described above, the float member 144 may fall slightly due to the condensed water falling and pushing. For this reason, the controller 160 may determine that the water tank 130 is not at the full water level.

To prevent this, in one embodiment, when the float member 144 maintains the high water level position for a predetermined time, the high water level display of the display unit 170 until the water stored in the water tank 130 is discharged. Can be maintained.

That is, in order to prevent the control unit 160 from misleading the high water level of the water tank 130 by the shaking of the water stored in the water tank 130, the control unit 160 floats for a predetermined time (for example, 1 second or more). After the member 144 is continuously positioned at the highest rising height, even if the float member 144 is lowered, the display unit 170 may control the water level display to be maintained.

In addition, the water level display of the display unit 170 may be released when the water tank 130 is separated and the water stored in the water tank 130 is discharged.
