US Patent 10288989 Projector and panel for opening

A projector that projects an image on a screen includes a projection port for projecting the image in a direction tilting to the lower side with respect to the horizontal direction, a housing, and an exhaust panel provided in an exhaust port formed in the housing and configured to restrict a moving direction of the air discharged through the exhaust port. The exhaust port is formed on a right side surface toward a projecting direction of the image in the housing. The exhaust panel forms a channel that connects the inner side and the outer side of the housing. The channel has a tilt coming closer to a direction vertically opposite to the projecting direction of the image and closer to the screen from the inner side toward the outer side.
