Dehumidifier

Abstract

The present invention provides a dehumidifier capable of efficiently cooling a circuit board and a reactor without increasing the number of components. The dehumidifier according to the present disclosure includes: a casing having an air inlet and an air outlet; an air passage extending from the air inlet to the air outlet; an air-blowing means provided in the air passage to generate an airflow; a dehumidifying means disposed inside the casing to remove moisture contained in the airflow; and a control means disposed inside the casing to control operations of the air-blowing means and the dehumidifying means.The control means includes a circuit board and a reactor, which are arranged in a board housing space different from the air passage.The dehumidifier further includes a first communication port that connects the board housing space to an upstream side of the air passage relative to the dehumidifying means, and a second communication port that connects the board housing space to a downstream side of the air passage relative to the dehumidifying means.The first and second communication ports are connected to each other through the board housing space.
