1. An appliance, comprising:
- a dust separator;
a filter housing located downstream from the dust separator and including a filter therein; and
an exhaust duct configured to carry airflow from the filter housing,wherein the filter housing comprises at least one substantially non-linear vane positioned downstream of the filter for guiding airflow from an exhaust side of the filter to an inlet of the exhaust duct so as to spread airflow entering the exhaust duct across the width thereof,wherein the exhaust duct further comprises an airflow outlet to discharge the airflow from the device, andwherein the vane is positioned such that it is spaced from side walls of the exhaust duct in a cross-section through the proximal end of the exhaust duct.

Abstract
An exhaust assembly for an appliance includes a filter housing for retaining a filter and an exhaust duct which receives airflow from the filter housing. One or more vanes are positioned in the filter housing for guiding airflow from the exhaust side of the filter to the exhaust duct. The vanes spread the airflow entering the exhaust duct across the width thereof so as to reduce noise and to reduce the velocity of the exiting air. The exhaust duct increases in cross-sectional area in the direction of flow through the exhaust duct so as to further reduce the velocity of the exiting air.

18. An appliance, comprising:
-
a dust separator; a filter housing located downstream from the dust separator and including a filter therein; and an exhaust duct configured to carry airflow from the filter housing, wherein the filter housing comprises at least one substantially non-linear vane configured to contact an exhaust side of the filter and to guide airflow from the filter to an inlet of the exhaust duct such that the airflow is spread across a width of the inlet of the exhaust duct, wherein the exhaust duct further comprises an airflow outlet to discharge the airflow from the device, and wherein the vane is positioned such that it is spaced from side walls of the exhaust duct in a cross-section through the proximal end of the exhaust duct.
