Abstract

A liquid ejection device includes a transport section configured to transport a medium along a first axis, a liquid ejection section configured to eject a liquid to the medium, a housing that houses the transport section and the liquid ejection section, a fan disposed at an end section of the housing along a second axis, which intersects the first axis of the housing, and that feeds air into the housing, a flow path member in which are formed an opening along the second axis and a flow passage for guiding air that was fed by the fan, a first partition plate disposed in the flow path and configured to guide, toward the opening, air fed along the second axis, and a second partition plate disposed in the flow path and configured to guide, toward the opening, air fed along the second axis.

Dependent claims

A liquid ejection device comprising:

a transport section configured to transport a medium along a first axis;
a liquid ejection section configured to eject a liquid to the medium transported along the first axis;
a housing that houses the transport section and the liquid ejection section;
a fan that is disposed at an end section of the housing along a second axis, which intersects the first axis of the housing, and that feeds air into the housing;
a flow path member in which are formed an opening along the second axis and a flow passage for guiding air that was fed in by the fan;
a first partition plate that is disposed in the flow path and that is configured to guide, toward the opening, air fed along the second axis;
and
a second partition plate that is disposed in the flow path and that is configured to guide, toward the opening, air fed along the second axis, wherein
the flow path has a first flow path section configured to guide air along the second axis and a second flow path section configured to guide air toward the opening,
the first partition plate is arranged at a position closer to the fan than is the second partition plate,
the first partition plate and the second partition plate are provided in the first flow path section and the second flow path section, and
a first part of the first partition plate arranged in the first flow path section is narrower than a second part of the second partition plate arranged in the first flow path section.
