Then, when the stopper 18 of the discharge pipe 12 is opened and the branch pipe 14 is closed with the stopper 20, the water in the reservoir 2 is discharged outside the dehumidifier through the discharge pipe 12 as shown in FIG. Discharged continuously.

In addition, when the stopper 18 of the discharge conduit 12 is closed and the drainage pump 16 is driven while the stopper 20 of the branch conduit 14 is opened, the water in the reservoir 2 is discharged as shown in FIG. It is discharged to the outside of the dehumidifier through the branch pipe (14). That is, the dehumidifier according to the present invention has three drainage modes.

Therefore, a suitable drainage mode can be selected according to the needs of the user. That is, the water of the reservoir 2 is drained to the water storage tank 10 through the drain port 8, or continuously drained to the outside of the dehumidifier through the discharge pipe 12 or the drive of the drain pump 16 As can be automatically discharged through the branch pipe (14).

The drainage pump 16 is connected to the discharge line 12 even when the driving is stopped, so that the water in the reservoir 2 is continuously drained along the discharge line 12 even though the drainage pump 16 is not driven. Can be.

The drain pump 16 may be a well-known geared pump that combines a motor and a reduction gear device into one to exert a high output as a small motor.

By using the geared pump it is possible to obtain a high output while minimizing the volume, so that even if the length of the discharge pipe 12 is long it is possible to obtain a sufficient output to discharge the water in the reservoir (2).

In addition, the dehumidifier provided with a simple automatic drainage structure of the dehumidifier according to the present invention is installed so that the water level sensing device is installed in the reservoir 2, the drain pump 16 can be driven / stopped according to the water level of the reservoir 2 do.

The water level detecting device operates in a switched-on state when the float 22 that elevates in accordance with the water level of the reservoir 2 and the water level of the reservoir 2 rises or exceeds a predetermined level according to the elevation of the float 22, When the water level of the water storage unit 2 is below a predetermined level it includes an operation switch 24 for operating in the switch-off state to drive / stop the drain pump 16.

The operation switch 24 is a member that performs a switching action of attaching or falling a contact, for example, by a magnetic force of a magnet. Such an operation switch 24 is electrically connected to a control unit (not shown) provided in a dehumidifier. 24, the driving of the drain pump 16 is turned on / off under the control of the controller.

Accordingly, when the water level of the water storage part 2 is lower than the predetermined water level, the float 22 and the operation switch 24 maintain a distance within a predetermined interval, and thus are switched off, so that the drain pump 16 does not drive and the water storage part ( When the water level of 2) is above a certain level, the interval between the float 22 and the operation switch 24 is widened by a predetermined interval or more, and the switch-on state is driven to drive the drain pump 16.

Thus, the water of the reservoir 2 can be automatically discharged by the water level sensing device consisting of the float 22 and the operation switch 24 and the drain pump 16 which stops driving / driving according to the detection of the water level sensing device. have.

The operation switch 24 that performs the switching action above may use a reed switch, a micro switch (limit switch), a constant voltage sensor, or the like.

In addition, a backflow prevention device 28 may be further installed in the discharge line 12 between the reservoir 2 and the drain pump 16, and the backflow prevention device 28 may be formed of, for example, a check valve. Can be.

The backflow prevention device 28 serves to prevent water from flowing back when the water in the reservoir 2 is automatically discharged by the driving of the drain pump 16 driven by the water level sensing device.

As described above, the dehumidifier provided with a simple automatic drainage structure of the dehumidifier according to the present invention drains the water of the water storage unit 2 to the water storage tank 10 through the drain port 8 or is manually drained or connected to the water storage unit 2. Continuously drained through the discharge pipe 12, or can be automatically discharged by the drive of the drain pump 16 is driven by the water level sensor installed in the discharge pipe (12).

Accordingly, the user may select the drainage method of the most convenient way according to the use place and the installed position of the dehumidifier to drain the water of the reservoir 2.

At this time, if the place where the water of the reservoir 2 is finally discharged away from the place where the dehumidifier is installed, it may be used by connecting the extension pipe 26 to the discharge pipe 12 or the branch pipe 14.

To use the dehumidifier provided with a simple automatic drainage structure of the dehumidifier according to the present invention as described above, when the power is supplied to the dehumidifier, the fan is driven and the air is sucked into the dehumidifier to remove moisture from the air from the dehumidifying means, followed by dry air. It is discharged to the outside.

At this time, the sucked air constitutes a dehumidification means and is cooled to below the dew point while passing through the heat exchanger (4) through which the refrigerant is circulated, and the moisture contained in the air is formed with dew. Dropped to (2) and stored.

In order to manually drain the water collected in the reservoir 2 through the reservoir tank 10, first, the

stoppers

18 and 20 are inserted into the discharge pipe 12 and the branch pipe 14, respectively. 2) When the water level is higher than a certain level as the water gathers, the water in the reservoir 2 naturally falls through the drain port 8 and is drained into the reservoir tank 10 (see FIG. 4).

And when a certain amount of water is stored in the storage tank 10, the user checks this, separates the storage tank 10 from the dehumidifier to empty the water and re-install it in the dehumidifier.

In addition, to continuously drain the water collected in the reservoir 2 to the outside of the dehumidifier, by removing the plug 18 inserted into the discharge pipe 12 in the above state, the water collected in the reservoir 2 is discharge pipe (12). ) And then drain out continuously to the outside of the dehumidifier (see FIG. 5).

At this time, if necessary, the extension pipe line 26 may be connected to the discharge pipe line 18.

In addition, to automatically drain the water in the reservoir 2 using the drainage pump 16, first plug the stopper 18 in the discharge conduit 12 and the stopper 20 of the branch conduit 14 is removed.

In this state, when the water level of the water storage part 2 is below a certain level, the float 18 and the operation switch 24 maintain a switched off state, and the drainage pump 16 maintains a stopped state. Since the end portion is in a position higher than the reservoir 2, the water of the reservoir 2 is not drained.

If this state continues and the water dehumidified by the dehumidification means in the reservoir 2 continues to rise and the water level rises, the float 22 will continue to rise as the water level.

When the water level of the water storage part 2 reaches a certain height, the interval between the float 22 and the operation switch 24 becomes greater than a predetermined interval, the switch-on state is driven, and the drain pump 16 is driven by the signal. .

In this way, the water of the reservoir 2 by the drain pump 16 is discharged to the discharge pipe 12 can be discharged to the outside of the dehumidifier through the branch pipe (14).

In this way, the water in the reservoir 2 is discharged, the water level of the reservoir 2 is lowered, and the float 22 is lowered as well. When the float 22 is lowered to the position close to the operation switch 24, the switch is switched. While being switched off, the driving of the drain pump 16 is stopped by the control of the controller, and at the same time, the discharge of the water discharged to the branch pipe 14 is also stopped.

Accordingly, when the water dehumidified by the dehumidifying means collects a certain amount in the reservoir 2, the drain pump 16 is driven and drained to the outside of the dehumidifier. When the water of the reservoir 2 is discharged by a predetermined amount, the drain pump 16 is discharged. By repeating the process of stopping the discharge on the water while the drive is stopped to automatically discharge the water of the reservoir 2 to the outside of the dehumidifier.

At this time, the water discharged to the discharge line 12 due to the backflow prevention device 28 may be discharged without backflow.

Although the preferred embodiments of the present invention have been described for purposes of illustration, the present invention is not limited thereto, and various modifications can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings.
