Retractable electric cord receiving device and ventilation apparatus
First Claim
1. An electrical appliance comprising:
- a handheld portable vacuum device having a removable dirtcup, an electrically powered component, and a cord winding mechanism, the cord winding mechanism comprising;
a cord receiving member, the cord receiving member being adapted to receive a cord, said cord receiving member defining an interior space inside said cord receiving member and having a first axis;
wherein said cord receiving member receives at least part of the electrically powered component inside the interior space of said cord receiving member to maintain a compact size;
wherein the cord winding mechanism is located inside a housing of the handheld portable vacuum device, and the dirt cup is attached to an exterior side of the housing;
wherein the cord winding mechanism is adapted to rotate about the first axis; and
wherein air that has been filtered by the removable dirtcup moves through the interior space of the cord receiving member in a direction substantially parallel to the first axis so as to cool the electrically powered component.

Abstract
A cord winding mechanism for an electrically powered device such as a vacuum cleaner. The cord winding mechanism may be used with a device having an electric motor. The mechanism may include a cord receiving member for receiving a cord. The cord receiving member may define an interior space and have an axis. The mechanism may include a biasing member that may transmit a rotational force to the cord receiving member to rotate the cord receiving member about the axis. The mechanism may include a retention member that may selectively prevent the cord receiving member from rotating under the rotational force of the biasing member. The cord receiving member may be adapted to receive at least part of the motor inside the interior space of the cord receiving member. The mechanism may include ventilation openings for providing ventilation An electric motor assembly may include the mechanism and a motor. An electric appliance may include a housing and the assembly.
