A bathroom dehumidifier according to 3.   A dehumidification rotor that is divided into an adsorption area that adsorbs moisture with rotation and a regeneration area that releases moisture, and an intake air passage that has an intake air blower on the way from the suction port that can communicate with the bathroom to the branching damper And an exhaust air passage that branches off from the branch damper and communicates with the outside of the bathroom, and a dehumidification air passage that branches off from the branch damper and passes through the adsorption area of the dehumidification rotor to the air outlet that can communicate with the interior of the bathroom. In the dehumidifying device for a bathroom, comprising a regeneration air passage that passes through the regeneration region of the dehumidifying rotor, and a control device that controls a switching operation tool for the motor and the branching damper of the intake fan, An air volume integration unit that integrates the air volume passing through the road is operated, and based on the dehumidification start command, the switching operation tool of the branch damper is operated and the intake The dehumidifying operation to start the motor of the machine and the switching operation tool of the branch damper so that the intake air passage and the exhaust air passage are communicated, and the ventilation volume value integrated by the air volume integrating unit The circuit configuration is such that the ventilation operation for starting the motor of the intake fan until the predetermined volume value is reached and the ventilation stop operation for stopping the motor of the intake fan are forcibly executed in this order. Dehumidifier for bathroom.
