PURPOSE:To allow an easy selection of a condition in which a full circulation function is to be made or a condition in which the air cleaning function is desired by providing two separate air intake passages of a passage which is connected to the room through a filter and a passage which is directly connected to the room without filter. CONSTITUTION:When a damper 9 is closed, the intake airflow is led into a casing 4 after being cleaned by passing from an intake grill 7 through a dust filter 5 and a deodorant filter 6, and is released into the room from an outlet grill 8. In this instance, as the circulation flow all passes through the dust filter 5 and the deodorant filter 6, a high air cleaning function is obtained. On the other hand, when the damper 9 is opened, an air intake passage that does not include the filters 5, 6 is formed, and so, the airflow rate is increased to highten the circulation function. Therefore, by operating a puall switch 10, an easy selection can be made between the high air cleaning function and the high circulation function. |
