Abstract

A cooled cord reel is provided for use with an electrical appliance. The cord reel includes a hub, a pair of cord retaining flanges mounted on the hub, a terminal block mounted in the hub and an electrical cord coiled on the hub and between the retaining flanges. Apertures are provided on the cord retaining flanges to permit cooling air flowing inwardly into the coiled cord and outwardly through it. The cord reel, additionally, has apertures in the cylindrical surface of its hub and slots through the terminal block to permit cooling air from within the hub to flow outwardly through the slots of the terminal block and the apertures of the hub.

Claims

1. A cooled cord reel cooled by allowing cooling air passing therethrough including;

(a) a hub for the reception of a coiled cord,

(b) a terminal block for connection of said coiled cord, attached to said hub,

(c) a bore in said hub for allowing at least a portion of said cooling air passing therethrough, and

(d) slots in said terminal block communicating with said bore for allowing at least a fraction of said portion of cooling air exhausting therethrough.

2. A cooled cord reel as set out in claim 1 wherein;

(a) said cooled cord reel includes a relatively fixed housing,

(b) said fixed housing having means for allowing the passing of a total cooling air flow,

(c) only a portion of said total cooling air flows passing through said bore of said hub.

3. A cooled cord reel as set out in claim 2 wherein;

(a) a hollow shaft is disposed in said hub,

a portion of said total flow of cooling air passes into said shaft and exhausts through a slot disposed in said shaft.
