Dehumidifier

Provided is a dehumidifier (1) capable of efficiently selecting an air purification operation and a dehumidification operation. The dehumidifier (1) is provided with: a first air passage which is formed inside the housing (3) and through which an air flow passes through the air purification unit and reaches the dehumidification unit; a second air path that is formed inside the housing (3) and that allows the air flow to reach the dehumidification unit without passing through the air purification unit; an air flow restricting means (51) that restricts the flow of the air flow in the second air path; a compressor (6) that supplies a refrigerant to the dehumidification unit; and a control device (18) that controls the blower unit, the airflow restriction unit (51), and the compressor (6). The control device (18) controls the airflow restriction unit (51) in accordance with at least one of the environmental information and the surroundings information. 本发明提供能够高效地选择空气净化运转和除湿运转的除湿机(1)。除湿机(1)具有：第一风路，其形成于框体(3)的内部，使气流
