Abstract: A dehumidifier includes a housing, an evaporator, a condenser, a liquid condensing device, and a fan. The evaporator and the condenser are arranged in sequence in a first direction. A plurality of liquid condensing pipes in the liquid condensing device extend in a second direction, are communicated with a second air channel, and are located in a first region, a second region, and a third region. The first region, the second region, and the third region are arranged in sequence in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. A contact area between the liquid condensing pipes in the second region and air in a first air channel is greater than contact areas between the air in the first air channel and the liquid condensing pipes in the first region and the third region.

Abstract: A dehumidifier is provided. The dehumidifier includes a housing, a machine body, a drainage pipe, and a sealing plug assembly. The housing includes a back plate and a drainage hole. The back plate includes an inner surface and an outer surface. The drainage hole is located in the back plate. The drainage pipe includes an extending portion, and the extending portion extends along a direction of the inner surface of the back plate towards the outer surface. The sealing plug assembly includes a sealing plug body, and the sealing plug assembly is configured to seal the drainage hole. The sealing plug body is detachably connected to the extending portion. The sealing plug body includes a first cavity. The first cavity is located at a side of the sealing plug body proximate to the machine body. At least a portion of the extending portion is sealingly connected to the first cavity.
