Projection display device
A projection display device includes: a leg section that supports a main body of the projection display device with respect to an installation surface on which the main body is installed; and a filter section that is disposed on a bottom of the main body and exposes a first air intake surface to the outside. In this arrangement, the first air intake surface is inclined with respect to the bottom surface of the main body in a direction that departs from the installation surface, and air flows into the filter section through a clearance between the first air intake surface and the installation surface.
1. A projection display device, comprising:
a leg section which supports a main body of the projection display device with respect to an installation surface on which the main body is installed; and
a filter section which is disposed on a bottom of the main body and takes in external air from a first air intake surface exposed to the outside of the main body to remove dust from the external air,
wherein the first air intake surface is inclined with respect to the bottom surface of the main body in a direction that departs from the installation surface, and air flows into the filter section through a clearance between the first air intake surface and the installation surface,
wherein the filter section includes a second air intake surface formed at an end portion of the first air intake surface closer to the installation surface and less inclined than the first air intake surface,
wherein a filter housing section which houses the filter section is provided on a bottom of the main body, the filter housing section includes a first surface more distant from the installation surface than a bottom surface of the main body and a second surface connecting the bottom surface of the main body with the first surface, and the first surface and the second surface each have an air inlet for taking air having passed through the filter section into the main body, and
wherein the filter section includes a first air discharge surface inclined in a direction that departs from the first surface, and a clearance is produced between the first discharge surface and the second surface.
2. The projection display device according to claim 1 , wherein
the filter section includes a second air discharge surface formed at an end portion of the first discharge surface closer to the first surface and less inclined than the first air discharge surface.
3. The projection display device according to claim 1 , wherein
the filter section has a vent hole for flowing air into the filter section, on an end surface opposite to the second surface with the first surface therebetween.
4. The projection display device according to claim 1 , wherein
the first air intake surface has a rib formed for preventing adhesion of a foreign matter to the first air intake surface.
