Abstract

An air blower including a casing having an intake port and a discharge port an air-blowing fan disposed inside the casing to take in air through the intake port and discharge air from the discharge port; and a filter filtering the air taken in through the intake port, wherein an insect trapping part trapping an insect is disposed in a ventilation path between the intake port and the filter.

First claim

The invention claimed is:

1. An air blower, comprising:
a casing having an intake port and a discharge port;
an air-blowing fan disposed inside the casing to take in air through the intake port and discharge air from the discharge port; and
a filter filtering the air taken in through the intake port, wherein
an insect trapper trapping an insect is disposed in a ventilation path between the intake port and the filter

the casing comprises:
a first casing holding the air-blowing fan; and
a second casing attached to the first casing in a detachable manner, and
the insect trapper is held in the second casing in a replaceable manner.

2. The air blower according to claim 1 , wherein an insect attractor attracting an insect is disposed in the ventilation path.

3. The air blower according to claim 1 , wherein a net part is disposed between the filter and the insect trapper.

4. The air blower according to claim 1 , wherein the intake port is formed in a shape of a slit.

5. The air blower according to claim 1 , wherein
the insect attractor is constituted by a light source, and
a peripheral part of the intake port is constituted by a translucent member.

6. The air blower according to claim 1 , wherein
the casing includes a recess,
the intake port is located at a bottom of the recess, and
at least one of the two side surfaces of the recess facing each other is inclined with respect to the casing such that a distance between the two side surfaces facing each other is shorter at a side of the intake port than the distance at a side opposite to the intake port.

7. The air blower according to claim 1 , wherein
the casing includes:
two facing parts facing each other; and
a side surface part located between the two facing parts, and wherein

the side surface part is formed as a curved surface protruding toward a side where one of the facing parts is located or as an inclined surface with an outer surface of the side surface part oriented toward a side where one of the facing parts is located and
the intake port is located at the side surface part.

8. The air blower according to claim 7 , wherein a peak wavelength of the light source is set at approximately 360 nm or the light source emits near-ultraviolet light.

9. The air blower according to claim 1 , wherein
a front part with an opening of the second casing is attached to a back surface of the first casing, and
the insect trapper is put on an inside surface of a back part of the second casing.

10. The air blower according to claim 1 , wherein the casing is colored with black.
