The valve operation unit 132 is not particularly limited, and may be configured in any form capable of opening the check valve 140 according to the mounting operation of the water container 130.

In addition, in an embodiment, when the bucket 130 is completely mounted on the housing, a portion disposed directly under the overflow prevention unit 150 to be described later may be opened. Through this, the condensed water discharged through the overflow prevention unit 150 may be accommodated into the water container 130.

The water container detection sensor 160 may detect whether the water container 130 is mounted on the device body.

The water container detection sensor 160 is not particularly limited, and may be configured in various forms such as a reed switch, a micro switch, and a magnetic switch installed in the water container 130 and the housing.

Although not shown, the water container detection sensor 160 is connected to the control unit of the dehumidifier 100 according to an embodiment of the present invention, and controls the operation of the dehumidifier 100 by sensing the water container 130 mounted on the housing. can do. That is, in the dehumidifier 100 according to an embodiment of the present invention, when the bucket 130 is mounted on the housing, the dehumidifying operation may be performed, and when the bucket 130 is removed from the housing, the dehumidifying operation is stopped. I can.

The check valve 140 may be provided at the outlet 122 of the condensate tray 120 as shown in FIGS. 2 to 5 to open and close the outlet 122.

The check valve 140 may be opened or closed in conjunction with an operation in which the bucket 130 is detached from the housing.

Specifically, the check valve 140 may be configured to open when the bucket 130 is completely mounted on the housing, that is, the original position of the housing, and close when the bucket 130 is removed from the housing or installed incompletely.

In one embodiment, the check valve 140 is disposed through the outlet 122 formed in the bucket 130 as shown in FIG. 3 and protrudes in the removal direction of the bucket 130, and the The packing 144 is coupled to the rod 142 and provided on the inside of the condensate tray 120 to open and close the outlet 122 according to the operation of the rod 142, and is coupled to the rod 142 to remove external force. If the packing 144 may be configured to include an elastic member 146 for elastically supporting the rod 142 to close the outlet 122.

In the check valve 140 of this configuration, when the water tank 130 is mounted on the housing, the valve operation part 132 of the water tank 130 presses the rod 142 so that the packing 144 is spaced apart from the outlet 122 The outlet 122 can be opened.

The overflow prevention unit 150 is provided in the condensate tray 120, and when the condensate water stored in the condensate tray 120 exceeds a certain level when the water container 130 is mounted but the outlet 122 is closed, the condensate water Condensed water stored in the tray 120 may be guided to the water container 130 and discharged.

Here, in the case where the water container 130 is mounted but the outlet 122 is closed, the check valve 140 is not opened because the water container 130 is incompletely mounted on the device body, and the check valve ( In a structure without 140), there are cases in which the outlet 122 is closed by a water film or foreign matter.

The overflow prevention unit 150 includes condensate water stored in the condensate tray 120 when the dehumidifier 100 according to an embodiment of the present invention performs a dehumidification operation while the outlet 122 is closed as described above. It constitutes a passage that can be discharged to the bucket 130 without overflowing to the sidewall of the tray 120.

To this end, in one embodiment, the overflow prevention unit 150 surrounds the opening 152 formed on the inner bottom of the condensate tray 120 and the condensate at the inner bottom of the condensate tray 120 It may be configured to include a wall protruding upward to a height lower than the sidewall of the tray 120.

Meanwhile, in the overflow prevention unit 150, a water film may be formed on the opening 152 or the top of the wall due to the narrow flow path, so that the condensate may not be discharged smoothly.

Accordingly, the overflow prevention unit 150 may be configured such that the opening 152 has a form in which it is difficult to form a water film, for example, a cross shape, as shown in FIG. 2.

However, the overflow prevention unit 150 is not limited to the above-described configuration, and may be configured as an opening formed in the wall surface of the condensate tray 120, or formed on the upper wall surface of the outlet 122 of the condensate water tray 120. It may also consist of an opening.

If the condensed water falling from the heat exchanger 110 falls directly into the water container 130 through the overflow prevention unit 150, the water dropping noise is severely generated, and the condensate water tray 120 and the check valve 140 There is a problem that the necessity disappears.

In the dehumidifier 100 according to an embodiment of the present invention, as shown in FIG. 4, the water container 130 is completely mounted on the housing so that the water container detection sensor 160 detects the water container 130 and check valve When the 140 is opened, the condensed water stored in the condensate tray 120 can be stored in the water container 130 through the opened outlet 122 when the dehumidification operation is performed.

On the other hand, as shown in FIG. 5, when the water container 130 is incompletely mounted on the device body and the water container detection sensor 160 detects the installation of the water container 130, but the outlet 122 is not open, dehumidification When the operation is performed, condensed water is collected in the condensed water tray 120.

At this time, when condensed water collects in the condensate tray 120 to a water level higher than the wall of the overflow prevention unit 150, the condensed water stored in the condensate tray 120 is discharged to the water container 130 through the overflow prevention unit 150 Can be.

Through this, the dehumidifier 100 according to an embodiment of the present invention has the advantage that condensate water does not overflow from the condensate tray 120 and can be safely discharged to the bucket 130 even when the bucket 130 is incompletely mounted on the housing. Have.
