Air cleaner

An air cleaner which sucks outside air through an air filter following rotation of a blower disposed in an air flow passage, cleans the sucked air, and sends out the cleaned air to the outside, the air cleaner comprising:

• an air flow passage that extends from the air filter to the blower branches off into a first air flow passage and a second air flow passage which join with each other again;
• a humidifying filter that contains water is disposed in the first air flow passage;
• a movable plate that is disposed in the second air flow passage to open and close the second air flow passage;
• a recess portion that is formed at a front of a main body and houses the air filter;
• and
• an air flow passage that extends inward from an lower portion of the recess portion, turns upward, and leads to the blower, and the air flow passage is partitioned into upper and lower portions to form the first air flow passage and the second air flow passage in order from the bottom,
• wherein the movable plate is a curved plate that is curved into an arc shape about a pivotal shaft extending along a right-to-left direction and rotates about the pivotal shaft, the movable plate rotates to the most forward position to close the second air flow passage, and rotates to the most backward position not only to open the second air flow passage but also to close a join opening of the first air flow passage, and
• a control portion that controls open and close operation of the movable plate and rotation operation of the blower is disposed.
