Abstract
There is provided an air cleaner including: an outlet pipe through which air is discharged; an airflow meter that is inserted toward an interior of the outlet pipe through a wall of the outlet pipe; and a flow-regulating member that is formed projecting from an inner surface of the outlet pipe at a leading end side of the airflow meter, the flow-regulating member including an edge that is formed with a peaked shape with respect to the inner surface and that runs along a direction of flow of air, a rear end that is formed at a downstream end of the edge in the direction of flow, and that is shaped cut sharply toward the inner surface and a width-narrowing portion that decreases in width in a circumferential direction of the outlet pipe on progression downstream in the direction of flow.
Claims6
An air cleaner comprising:
- an outlet pipe through which air is discharged;
- an airflow meter that is inserted toward an interior of the outlet pipe through a wall of the outlet pipe;
- a flow-regulating member that is spaced apart from and faces the leading end side of the airflow meter in a radial cross-section of the outlet pipe including the air flow meter, and that is formed projecting at an inner surface of the outlet pipe;
- and
- a housing that houses a filter element, the housing being connected to the outlet pipe such that a direction of passage of air through the filter element and a direction of flow of air in the outlet pipe cross each other,
- wherein the flow-regulating member is provided at an in-side of a flow path of air which curves from the direction of passage of air to the direction of flow, and the flow-regulating member includes:
- an edge that is formed with a peaked shape with respect to the inner surface and that runs along the direction of flow,
- a rear end that is formed at a downstream end of the edge in the direction of flow, and that has a shape that is sharply cut towards the inner surface, and
- a width-narrowing portion that decreases in width along a length of the width-narrowing portion in a downstream direction of the outlet pipe in the direction of flow.
