Abstract
An air cleaner having a filter, causing air to pass through the filter and discharging the filtered air. The air cleaner includes: an air duct having an inlet via which air is received and an outlet facing a first part of a main surface of the filter and via which the received air is output towards the first part of the main surface; a fan causing air to be received by the air duct via the inlet, to be output from the air duct via the outlet, and to pass through the filter; and a flow distributer disposed between the outlet and the filter. The flow distributer changes a direction of flow of air output from the air duct from towards the first part of the main surface to towards a second part of the main surface of the filter that does not facing the outlet.
Claims12
An air cleaner having a filter, causing air from an image forming device to pass through the filter and discharging the filtered air, the air cleaner comprising:
- an air duct having an inlet via which air from the image forming device is received and an outlet facing a first part of a main surface of the filter and via which the received air is output in a direction towards the first part of the main surface;
- a fan causing air from the image forming device to be received by the air duct via the inlet, to be output from the air duct via the outlet, and to pass through the filter;
- and
- only a single flow distributer disposed between the outlet and the filter, the flow distributer changing a direction of flow of air output from the air duct from the direction towards the first part of the main surface to a direction towards a second part of the main surface of the filter, the second part being a part of the main surface that does not face the outlet,
- wherein the flow distributer has a single conical mountain-shaped protrusion protruding towards the outlet.

- a fan causing air from the image forming device to be received by the air duct via the inlet, to be output from the air duct via the outlet, and to pass through the filter;
- and
- a flow distributer disposed between the outlet and the filter, the flow distributer changing a direction of flow of air output from the air duct from the direction towards the first part of the main surface to a direction towards a second part of the main surface of the filter, the second part being a part of the main surface that does not face the outlet,
- wherein the flow distributer has a mountain-shaped protrusion protruding towards the outlet, and
- wherein the mountain-shaped protrusion has an asymmetric conical shape.
