Abstract
Official abstract text for this publication.
A battery-operated hair dryer comprises a battery (B), and a fan (F) having rotating fan blades propelled by a motor (M) that is powered by the battery (B), and non-rotating static air flow-shaping vanes (V) between the motor (M) and a motor mount (MM), which non-rotating static airflow-shaping vanes (V) serve as cooling ribs for the battery (B) that is mounted adjacent to the fan (F). Preferably, the battery (B) is positioned adjacent to a motor mount (MM) of the motor (M) of the fan (F). Advantageously, the battery (B) is at least partly positioned in a handle of the battery-operated hair dryer, the fan (F) being positioned adjacent to the handle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A battery-operated hair dryer comprising: a hair dryer housing; a battery; and a fan having rotating fan blades propelled by a motor that is powered by the battery, wherein: around the motor, the fan has non-rotating static airflow-shaping vanes between the motor and a motor mount, the non-rotating static airflow-shaping vanes mounted around or against the motor mount, and serving as cooling ribs for the battery that is mounted adjacent to the fan, the motor mount being between the non-rotating static airflow-shaping vanes and the dryer housing; and the battery is mounted around or against the motor mount. 2. A battery-operated hair dryer as claimed in claim 1 , wherein the battery is partly positioned in a handle of the battery-operated hair dryer, the fan being positioned adjacent to the handle.
