Abstract

A collection apparatus collects a collection target in air in a target space. The collection apparatus includes an air passage having an inlet and an outlet, a carrier disposed in the air passage, and a plurality of collectors disposed in the air passage. The carrier carries the air. The plurality of carriers collects the collection target in the air carried by the carrier. The plurality of collectors collects different types of collection targets.

First claim

1 . A collection apparatus configured to collect a collection target in air in a target space, the collection apparatus comprising:
an air passage having an inlet and an outlet; a carrier disposed in the air passage, the carrier being configured to carry the air; and a plurality of collectors disposed in the air passage, the plurality of carriers being configured to collect the collection target in the air carried by the carrier, the plurality of collectors being configured to collect different types of collection targets.

2 . The collection apparatus of claim 1 , wherein
the plurality of collectors include
a solid collector configured to collect a solid component as the collection target and
a gas collector configured to collect a gas component as the collection target.

3 . The collection apparatus of claim 2 , wherein
the solid collector is disposed upstream of the gas collector in the air passage.

4 . The collection apparatus of claim 2 , wherein
the solid collector is configured to collect at least one of a suspended microorganism, a suspended allergen, a mineral, and an organic compound as the solid component.

5 . The collection apparatus of claim 2 , wherein
the gas collector is configured to collect at least one of a volatile organic compound and an odor gas as the gas component.

6 . The collection apparatus of claim 2 , wherein
the air passage includes a plurality of first channels and a single second channel, downstream ends of the plurality of first channels communicate with an upstream end of the second channel, the solid collector is disposed in each of the plurality of first channels, and the gas collector is disposed in the second channel.

7 . The collection apparatus of claim 6 , further comprising:
a first mechanism configured to switch a target first channel between the plurality of first channels and allow the air to enter the target first channel and flow through the second channel.

8 . The collection apparatus of claim 7 , wherein
the first mechanism includes a first opening and closing mechanism
provided upstream of each of the solid collectors in the plurality of first channels and
configured to open and close the first channel corresponding to the first opening and closing mechanism.

9 . The collection apparatus of claim 1 , wherein
the inlet opens upward.

10 . The collection apparatus of claim 9 , wherein
the outlet opens laterally.
