Kind Code:
A1
Abstract:
The present invention relates to an air cleaning device. A housing has an inlet formed on one side thereof through which contaminated air is introduced from an indoor space and an outlet formed on an opposite side thereof through which purified air is discharged to the outside. A first opening/closing member opens and closes the inlet. A second opening/closing member opens and closes the outlet. A first filter unit collects and separates foreign substances from contaminated air in the housing and is disposed such that opposite end portions thereof are directed toward the inlet and the outlet, respectively, in a state in which the outer peripheral portion of the first filter unit is brought into close contact with the inner peripheral portion of the housing so that no air can pass therebetween. A circulation tube has a first end portion disposed at the inlet side to communicate with the housing and a second end portion disposed at the outlet side to communicate with the housing. A third opening/closing member opens and closes the circulation tube. A first heater is installed inside the circulation tube to heat air in the circulation tube. A blower is installed inside the circulation tube to deliver air in the circulation tube into the housing.
