Image forming apparatus with natural ventilator

摘要

An image forming apparatus includes an outside air inlet created between a cover and a body plate, through which outside air is taken in. A vent is created between the body plate and the cover. The outside air taken in through the outside air inlet travels through an air current channel upward to the vent in an outside air traveling direction. At least one hot air outlet is produced through the body plate at a position between the outside air inlet and the vent in the outside air traveling direction. Hot air is discharged into the air current channel through the at least one hot air outlet. The outside air taken in through the outside air inlet is mixed with the hot air discharged through the at least one hot air outlet and is exhausted through the vent.

主权项

1. An image forming apparatus comprising:
a body plate; a cover disposed opposite the body plate; an orthogonal plate projecting from a lower edge of the cover orthogonally toward the body plate; an outside air inlet created between the orthogonal plate and the body plate, through which outside air is taken in, the outside air inlet being disposed in a plane extending along a surface of the orthogonal plate while the cover is closed; a vent created between the body plate and the cover at an upper edge of the cover; an air current channel in communication with the outside air inlet and the vent, the air current channel through which the outside air taken in through the outside air inlet travels upward to the vent in an outside air traveling direction; and at least one hot air outlet produced through the body plate at a position between the outside air inlet and the vent in the outside air traveling direction, the at least one hot air outlet through which hot air is discharged into the air current channel; a plurality of primary ribs mounted on an interior face of the cover disposed opposite the body plate and having a first length extending in the outside air traveling direction; a plurality of secondary ribs mounted on an exterior face of the body plate and having a second length extending in the outside air traveling direction smaller than the first length of the plurality of primary ribs, wherein the at least one hot air outlet includes a plurality of hot air outlets aligned in parallel to each other and each of the plurality of secondary ribs is disposed at a gap between adjacent hot air outlets, wherein each of the plurality of secondary ribs is interposed between the adjacent primary ribs in a direction orthogonal to the outside air traveling direction, and wherein the outside air taken in through the outside air inlet is mixed with the hot air discharged through the at least one hot air outlet and is exhausted through the vent.
