PROBLEM TO BE SOLVED: To make it possible to expect an energy saving effect by making ventilation and circulation switchable with a simple structure.SOLUTION: An air treatment device comprises: an air intake; an air duct above the air inlet; a blower arranged in parallel to the air duct; a chamber that includes an exhaust air duct communicating with outdoor space, a circulation air duct connected to an indoor opening, an air supply duct connected to the outdoor space in parallel to the exhaust air duct and communicating with the circulation air duct, a switching damper switching a direction of the air between the exhaust air duct and the circulation air duct, and an air supply opening/closing damper opening/closing the air supply duct; a deodorizer provided on the circulation duct-side indoor opening and including a deodorant and a heater; a first space isolated to a lateral side of the exhaust air duct outside of the chamber by a partition plate; and a second space isolated to the lateral side of the air supply duct outside of the chamber by a partition plate, and provided on an opposite side to the first space across the exhaust air duct and the air supply duct. In the first and second spaces, a switching device for the air duct switching damper, a switching device for the air supply opening/closing damper, and a wiring element of the heater are arranged. |
