Hereinafter, a control method of the humidifying / dehumidifying multi-function device of this embodiment will be described.

As shown in FIG. 20, the control method of the humidifying / dehumidifying multifunction device of this embodiment is a method of operating the humidification module when the humidity is equal to or lower than the first humidity and inputting the humidity control mode for operating the dehumidification module if the humidity is equal to or higher than the second humidity A second judgment step (S13, 17) of judging whether a new first humidity or a new second humidity is inputted, if it is inputted in the automatic humidity control mode, a first judgment step (S11) If the first humidity or the new second humidity has been input, changing the existing first humidity or the existing second humidity to the new first humidity or the new second humidity (S15, 19).

In the first judgment step S11, whether or not the humidification module is operated when the humidity is equal to or less than the first humidity and the automatic humidity control mode for operating the dehumidification module when the humidity is equal to or higher than the second humidity is inputted through the selection button 111 or the like .

If it is input in the automatic humidity control mode, it is determined whether a new first humidity is inputted through the first control button 112. [ (S13)

When the new first humidity is input, the existing first humidity is changed to the new first humidity (S15)

Then, it is determined whether a new second humidity has been inputted through the second control button 113. (S17)

If the new first humidity has not been input, it is determined whether a new second humidity has been input.

When the new second humidity is inputted, the existing second humidity is changed to the new second humidity (S19).

On the other hand, whether or not the first and second humidity settings are completed can be determined by receiving the selection button 111 once more. Alternatively, whether or not the setting is completed can be determined based on whether the adjustment button is pressed for a predetermined time after the selection button 111 is pressed.

Then, the humidifying / dehumidifying complex machine is operated in the automatic humidity control mode (S21)

The existing first and second humidities may be the first and second humidity previously input by the user.

Alternatively, the existing first and second humidity may be a predetermined value set in the controller. For example, the existing first humidity may be 40%, and the existing second humidity may be 70%. Therefore, when the user inputs the first and second humidity in the automatic humidity control mode without separately setting the first and second humidity, the first humidity is 40% and the second humidity is 70%.

As described above, the first humidity and the second humidity of the automatic humidity control mode can be adjusted according to the individual taste or situation of the user, thereby improving the user's convenience.

Hereinafter, the automatic humidity control mode method will be described in detail.

The automatic humidity control mode method of the present invention includes a humidification mode step (S1) for humidifying the disk with water wetted by water, a first judgment step (S3) for judging whether the humidity is above the second humidity, And a dehumidifying step (S11) for stopping the humidifying mode and changing to a dehumidifying mode if the humidity exceeds the second humidity.

In the humidification mode step S1, the disk of the disk assembly 300 wetted with water through the air blowing fan 600 is humidified by bringing air in the room into contact with each other.

Then, a first determination step (S3) is performed to determine whether the current humidity exceeds the second humidity.

The second humidity can be determined through experimentation and is 70% in the present embodiment.

A third determination step (S5) of determining whether the humidification mode has exceeded a predetermined time if the humidity exceeds the second humidity after the first determination step (S3); if the humidification mode is within the predetermined time, (S7) of turning off the compressor for compressing the refrigerant of the refrigerant circuit (S7).

In other words, the third determination step S5 determines whether the time that has entered the dehumidification mode again exceeds the predetermined time after operating in the humidification mode.

The predetermined time of the third determination step (S5) may be determined through experimentation, which is three minutes in the present embodiment.

In the off step S7, the compressor is turned off for a predetermined time, and then the compressor is turned on. That is, the compressor is operated in the dehumidification mode, and the compressor is turned on and delayed for a predetermined time.

Since the humidification and dehumidification are likely to be changed within a short time in a small space due to a large change in the humidity amount, it is possible to prevent the compressor from being turned on and off within a short time,

If the humidification mode has exceeded a predetermined time, the compressor is turned on.

Then, a dehumidification step (S11) is performed in which the humidification mode is stopped and then the dehumidification mode is changed. The dehumidification is performed through the heat exchange unit 400.

Next, a second determination step (S13) is performed to determine whether the current humidity is equal to or lower than the first humidity. If the humidity is equal to or lower than the first humidity, the dehumidification mode is stopped and then the mode is changed to the humidification mode (S1).

The first humidity can be determined through experimentation and is lower than the second humidity.

In the present embodiment, the first humidity is 40%.

In this way, the humidifying / dehumidifying complex machine is controlled, so that the space can be efficiently used, and dehumidification and humidification can be performed more effectively.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
