Abstract

A deodorization apparatus according to one aspect of the present invention includes: a first main wall 201 ; a second main wall 202 ; a first side wall 203 ; a second side wall 204 ; a first partition wall 205 with a gap with the second main wall; a second partition wall 206 with a gap with the first main wall; a photocatalyst unit 30 provided between the first main wall and the second main wall, and allowing air to pass therethrough in a direction from the second main wall to the first main wall; and a centrifugal blower 40 disposed opposite to the photocatalyst unit with respect to the second partition wall and spaced apart from the first main wall, the centrifugal blower 40 having a suction port that opens toward the first main wall and a discharge port that opens on a side facing away from the second partition wall.

First claim

What is claimed is:

1 . A deodorization apparatus comprising:
a first main wall; a second main wall facing the first main wall; a first side wall and a second side wall each sealing a space between a side edge of the first main wall and a side edge of the second main wall; a first partition wall disposed without a gap between the first partition wall and the first main wall and with a gap between the first partition wall and the second main wall; a second partition wall disposed without a gap between the second partition wall and the second main wall and with a gap between the second partition wall and the first main wall; a photocatalyst unit provided between the first main wall and the second main wall, and allowing air to pass therethrough in a direction from the second main wall to the first main wall; and a centrifugal blower disposed opposite to the photocatalyst unit with respect to the second partition wall and spaced apart from the first main wall, the centrifugal blower having a suction port that opens toward the first main wall and a discharge port that opens on a side facing away from the second partition wall.

2 . The deodorization apparatus according to claim 1 , further comprising:
a light source disposed adjacent to the second main wall and configured to emit light onto the photocatalyst unit; and a light shielding wall disposed opposite to the second partition wall with respect to the first partition wall, without a gap between the light shielding wall and the second main wall and with a gap between the light shielding wall and the first main wall.

3 . The deodorization apparatus according to claim 2 , further comprising:
a circuit board disposed on an outer side of the second main wall and having the light source mounted thereon, wherein the second main wall has a light projection aperture through which the light source is exposed.

4 . The deodorization apparatus according to claim 1 , wherein
the first side wall has, between the first partition wall and the second partition wall, an attachment/detachment opening through which the photocatalyst unit is inserted, and the first partition wall and the second partition wall each have a guide for guiding the photocatalyst unit.

5 . The deodorization apparatus according to claim 1 , wherein the photocatalyst unit comprises a photocatalyst carrier and a frame that holds the photocatalyst carrier, the photocatalyst carrier including a plate-shaped porous ceramic molding and a photocatalyst carried on the plate-shaped porous ceramic molding.
