Abstract

Provided is a dehumidifier capable of preventing condensation from flowing to the outside of a water container when the dehumidifier is turned over or while the dehumidifier is moved, since a suction structure for suctioning the condensation and a discharge structure for discharging the condensation are improved. The dehumidifier comprises: a main body having a suction port; a heat exchanger provided inside the main body and removing moisture in the air; and a water collection device for collecting the condensation generated in the heat exchanger, wherein the water collection device comprises: an auxiliary water container in which the condensation is collected; a housing for guiding the condensation to the auxiliary water container; a connection hose provided to have a bent part so as to connect the auxiliary water container and the housing; an upper water container detachably provided at the upper part of the main body so as to drain the condensation; and a pump for pumping, to the upper water container, the condensation collected in the auxiliary water container.

First claim

The invention claimed is:

1. A dehumidifier comprising:
a main body having a suction port to suction air;
a heat exchanger disposed in the main body to remove moisture from the air from the suction port; and
a water collection device configured to collect condensate generated in the heat exchanger,
wherein the water collection device comprises:
an auxiliary water container in which the condensate is collected;
a housing configured to guide the condensate toward the auxiliary water container;
a connection hose having a bent part and configured to connect to the housing and to a rear side of the auxiliary water container; the bent part being configured such that the condensate collected in the auxiliary water container has a lower level than the bent part;
an upper water container detachably mounted on an upper portion of the main body to drain the condensate therefrom; and
a pump configured to pump the condensate collected in the auxiliary water container into the upper water container, and

wherein a guide duct having a discharge port is provided in the main body, and the upper water container is provided to have a square shape having an opening at a center thereof, and the air guided to the discharge port is discharged to the outside through the opening.

2. The dehumidifier of claim 1 , wherein the housing is provided on a lower portion of the heat exchanger, and the housing comprises: a guide path provided on an upper portion of the housing to guide so that the condensate is collected into the auxiliary water container; and a connector having a connection hole therein and provided to extend downward from the guide path to be connected to the connection hose.

3. The dehumidifier of claim 2 , wherein the auxiliary water container is integrally provided with the housing.

4. The dehumidifier of claim 3 , wherein an upper portion of the auxiliary water container is open and the opened upper portion is covered by a cover, and a gasket is provided between the cover and the auxiliary water container to closely seal the inside of the auxiliary water container.

5. The dehumidifier of claim 4 , wherein a filter configured to filter foreign matter in the condensate before the condensate collected in the auxiliary water container is supplied to the pump is provided in the auxiliary water container.

6. The dehumidifier of claim 2 , wherein the connection hose includes:
a first connection hose having an end connected to the connector and an other end extending in a downward direction perpendicular to an upper surface of the housing;
a second connection hose having an end connected to the first connection hose and an other end extending forward to be connected to the rear side of the auxiliary water container; and
the bent part connecting the first connection hose and the second connection hose.

7. The dehumidifier of claim 6 , wherein the other end of the second connection hose extends to a position adjacent to a front side of the auxiliary water container through the rear side of the auxiliary water container.

8. The dehumidifier of claim 1 , wherein the water collection device further includes: a full-water level sensor to detect a full-water level of the auxiliary water container; and a low-water level sensor to detect an amount of the condensate remaining in the auxiliary water container.

9. The dehumidifier of claim 1 , wherein the pump is provided on the housing to be located at the outside of the auxiliary water container.

10. The dehumidifier of claim 9 , wherein the pump is provided to be accommodated in a pump cover to block noise generated when the pump operates from being transferred to the outside.

11. The dehumidifier of claim 10 , wherein the auxiliary water container and the pump are connected by a pump suction hose which suctions the condensate collected in the auxiliary water container to the pump, and the pump and the upper water container are connected by a pump discharge hose which discharges the condensate suctioned to the pump to the upper water container.

12. The dehumidifier of claim 1 , wherein the main body includes a front case, a rear case coupled to a rear face of the front case, and a base provided on lower portions of the front and rear cases, and the suction port is provided on the rear case.

13. The dehumidifier of claim 12 , wherein the guide duct is provided with a flow path to guide the moisture in the air suctioned through the suction port to be discharged to the discharge port after being condensed by the heat exchanger.

14. The dehumidifier of claim 13 , wherein the guide duct has a front guide duct and a rear guide duct coupled to a rear side of the front guide duct, and a blower fan is provided between the front guide duct and the rear guide duct to allow the air suctioned through the suction port to be guided to the discharge port.
