Embodiment Construction

[0110] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0111] Such as figure 1 As shown in (a) and (b), the projector 1 includes a housing 10 in which electronic components and optical components are incorporated. The projector 1 is a projection type image display device that projects and displays an image onto a flat surface such as a screen or a wall. Hereinafter, the direction in which the projector 1 projects the light of an image is referred to as the front in the front-rear direction. Furthermore, when the projector 1 is installed on a horizontal plane (not shown), a direction parallel to the horizontal plane and perpendicular to the front-rear direction is defined as the left-right direction.

[0112] Such as figure 2 and image 3 As shown, the projector 1 includes an optical system 2 for displaying images in a casing 10 . Inside the housing 10, lamps 21a, 21b, 21c, and 21d, which are light sources for image ...

Abstract

The present invention provides an air filter cleaning device capable of suppressing movement of dust adhering to a brush to an air filter when the brush and a dust box reciprocate, and a projection type image display device including the air filter cleaning device. The air filter device as an air filter cleaning device is equipped with an air filter for capturing dust, a brush (45) for cleaning the air filter, a dust box for accumulating dust adhering to the brush (45), and a rotating brush (45) The rotating shaft (43), the pinion gear (43A, 43B) as a propulsion mechanism for pushing the brush (45) and the dust box through the rotation of the rotating shaft (43), the brush (45) via the one-way clutch (44) and The rotary shaft (43) is connected.

Description

technical field [0001] The present invention relates to an air filter cleaning device provided with a brush for cleaning an air filter, and a projection type image display device provided with the air filter cleaning device. Background technique [0002] Generally, it is known that an air filter for capturing dust in the air that tends to flow into the housing is provided on a housing of a projector as a projection-type video display device. Also, a projector including a brush reciprocating in a predetermined linear direction to clean an air filter is disclosed (for example, refer to Patent Document 1). [0003] In addition, there is known an air filter cleaning device having a propulsion mechanism for propulsing a brush for cleaning the air filter and a dust box for accumulating dust adhering to the brush by rotation of a rotating shaft that rotates the brush. For example, Patent Document 2 discloses an air conditioner incorporating such a device. [0004] prior art liter...
