Abstract
A purification unit is provided with a light source which emits light, a purification plate which causes a photocatalysis reaction by irradiation with the light, and a reflection plate which has a curved surface configuration, and is configured to reflect the light emitted from the light source for guiding the reflected light to the purification plate. The layout of the light source and the curved surface configuration of the reflection plate are defined in such a manner that an intensity of the light to be applied to the purification plate is biased toward an upstream side of an air flow path in the purification unit.
Claims10
A purification unit for purifying air by a photocatalysis reaction, comprising:
- a light source which emits light;
- a purification plate which causes the photocatalysis reaction by irradiation of the light;
- and
- a reflection plate which has a curved surface configuration, and is configured to reflect the light emitted from the light source for guiding the reflected light to the purification plate, wherein
- a layout of the light source and the curved surface configuration of the reflection plate are defined in such a manner that an irradiation intensity of the light on the purification plate is biased toward an upstream side of an air flow path in the purification unit.
A deodorizing device, comprising:
- a purification unit which purifies air by a photocatalysis reaction;
- a fan which causes the air to flow into the deodorizing device;
- and
- a controller which controls the fan and a light source in the purification unit, wherein
- the purification unit is provided with:
- the light source which emits light;
- a purification plate which causes the photocatalysis reaction by irradiation of the light;
- and
- a reflection plate which has a curved surface configuration, and is configured to reflect the light emitted from the light source for guiding the reflected light to the purification plate, and
- a layout of the light source and the curved surface configuration of the reflection plate are defined in such a manner that an irradiation intensity of the light on the purification plate is biased toward an upstream side of an air flow path in the purification unit.
