Abstract
A motor housing for a vacuum cleaner includes a motor chamber supported within a main housing wall. A first airway defined between the motor chamber and the main housing wall provides a pathway for the working air flow within the vacuum cleaner. A second airway is defined through the motor chamber by an inlet opening and a venting outlet. The airway through the motor chamber allows air to flow along and directly encounter the motor during vacuum operation. The air flow through the first airway not only serves as the working air flow, but also as a secondary cooling air flow because the air passes along the exterior surface of the motor chamber and provides a cooling effect.
