Dehumidifier with cooling pipeline wound outside compressor

The invention provides a dehumidifier with a cooling pipeline wound outside a compressor. The dehumidifier comprises a machine shell, wherein a cavity is defined in the machine shell; the heat exchanger is arranged in the cavity and is configured to condense moisture in the air entering the cavity into condensed water; the water pan is arranged below the heat exchanger and configured to receive condensate water generated by the heat exchanger; the water pump is communicated with the water pan and is controlled to be opened so as to enable the condensate water to flow into the cooling pipeline; and the compressor is arranged in the cavity, and the cooling pipeline is arranged outside the compressor in a winding mode so that the compressor can be cooled through condensate water in the cooling pipeline. According to the dehumidifier, the compressor is cooled through the condensate water in the cooling pipeline wound around the outside of the compressor, the compressor can be effectively cooled, the working effic
