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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 2) The dehumidifier of claim 2, wherein the auxiliary water container is integrally provided with the housing. ### Claim 4 (depends on 3) 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. ### Claim 5 (depends on 4) 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. ### Claim 6 (depends on 2) 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. ### Claim 7 (depends on 6) 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. ### Claim 8 (depends on 1) 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. ### Claim 9 (depends on 1) The dehumidifier of claim 1, wherein the pump is provided on the housing to be located at the outside of the auxiliary water container. ### Claim 10 (depends on 9) 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. ### Claim 11 (depends on 10) 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. ### Claim 12 (depends on 1) 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. ### Claim 13 (depends on 12) 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. ### Claim 14 (depends on 13) 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.
