Abstract
An airflow device includes a motor to drive an impeller to cause a first airflow and a second airflow. A housing at least partially encloses the motor and impeller, and the housing defines at least a first path and a second path. Via the first path, the first airflow recirculates and is heated with the first path including a first wall with a nozzle array through which the first airflow passes to contact printed media passing external to the first wall. The second path receives a second airflow of air to travel alongside the motor and exit through a first port to join the first airflow at the impeller.
Claims18
A device comprising:
- a motor to drive an impeller to cause a first airflow and a second airflow;
- a housing at least partially enclosing the motor and impeller, and defining at least:
- a first path to recirculate the first airflow in a first temperature range;
- a second path to receive the second airflow, at a second temperature less than the first temperature range, to travel alongside the motor;
- a first wall along the first path and including a nozzle array through which the first airflow is to be forced via the impeller to contact printed media external to the first wall;
- and
- a second wall extending between the motor and the impeller and including at least one port through which the second airflow is to exit to join the first airflow adjacent the impeller,
- the first airflow and the second airflow to travel in a same direction along opposite sides of the second wall.
A device comprising:
- an image formation mechanism;
- and
- a dryer downstream a media path from the image formation mechanism and comprising:
- a motor to drive an impeller to cause a first airflow and a second airflow;
- and
- a housing at least partially enclosing the motor and impeller, and defining at least:
- a first heated path by which the first airflow is to recirculate and be heated;
- a first wall with a nozzle array through which the first airflow is to pass to contact printed media external to the first wall;
- a second wall separating the motor from the impeller along which the first airflow is to travel in a first direction;
- and
- a second non-heated path by which the second airflow is to travel in the first direction alongside the motor between the motor and the second wall and exit through at least one port to join the first airflow at the impeller,
- wherein the first airflow and the second airflow are to travel along opposite sides of the second wall.
A dryer downstream a media path from an inkjet print mechanism, the dryer comprising:
- a single motor to drive a single impeller to cause a first airflow and a second airflow;
- and
- a housing comprising:
- a first portion at least partially enclosing the single impeller and through which the first airflow is to recirculate and be heated, the first portion including a first wall with a nozzle array through which the first airflow is to pass to contact printed media passing external to the first wall;
- and
- a second portion at least partially enclosing the single motor separately from the single impeller and through which the second airflow is to travel alongside the motor, the second portion including a second wall with at least one port through which the second airflow joins the first airflow adjacent the impeller within the first portion,
- wherein the first airflow is to travel in a first direction along a first side of the second wall and the second airflow is to travel in the first direction along a second side of the second wall between the motor and the second wall opposite the first side.
