Abstract
A vacuum cleaner includes an upright body mounted to a base that moves over a surface to be cleaned. A rotational coupling can be provided between the upright body and the base for coupling the upright body to the base for movement about at least one rotational axis. The rotational coupling can include at least a swivel joint. A cord rewinder can be provided above the swivel joint for storing and dispensing a power cord.
Claims20
A vacuum cleaner, comprising:
- an upright body;
- a base adapted for movement over a surface to be cleaned and comprising a suction nozzle opening;
- a working air path which extends from a dirty air inlet to a clean air outlet;
- a power cord;
- a suction motor electrically coupled to the power cord and defining a portion of the working air path;
- a cord rewinder;
- and
- an air cooling pathway configured to direct air from the suction motor to the cord rewinder, the air cooling pathway extending partially exteriorly of the vacuum cleaner upstream of the cord rewinder.

- an upright body;
- a base adapted for movement over a surface to be cleaned and comprising a suction nozzle opening;
- a working air path which extends from a dirty air inlet to a clean air outlet;
- a collection assembly defining a portion of the working air path;
- a rotational coupling between the upright body and the base, wherein the rotational coupling comprises a swivel joint permitting movement of the upright body about a first rotational axis relative to the base;
- a power cord;
- a suction motor electrically coupled to the power cord and defining a portion of the working air path, the suction motor having a motor air outlet;
- a cord rewinder located above the suction motor;
- and
- an air cooling pathway for the cord rewinder that directs exhaust air from the motor air outlet to the cord rewinder, wherein a portion of the air cooling pathway extends exteriorly through the ambient environment prior to reaching the cord rewinder.
