Motor assembly for steam vacuum cleaner

Abstract

A motor assembly for a steam vacuum cleaner comprises a flow separation packing which is coupled within a motor cooling casing between a cold air intake duct and an air exhaust duct, so as to maximize cooling efficiency of a wet type motor by separating the sucked cold air from the hot air having undergone a cooling operation.

AI Technical Summary

Benefits of technology

[0009]To address deficiencies of the related art, it is, therefore, an object of the present invention to provide a motor assembly for a steam vacuum cleaner capable of maximizing cooling efficiency of a wet type motor by separating the cold air sucked into a motor drive unit from the hot air which is exhausted from the unit after having been used.

[0012]Preferably, the motor assembly further includes an impeller casing for guiding the discharged air outward in the circumferential direction from the motor drive unit. This structural feature enhances cooling efficiency of the motor drive unit even more.

Problems solved by technology

Because of this, the main body of the vacuum cleaner very large (having an undesirable height and width), making it difficult to maneuver the vacuum in order to clean under and / or around certain objects such as a bed or couch.

Additionally, because the main body of this vacuum is so bulky and large, its contact area with the floor is larger than many conventional vacuums.

Accordingly, this type of vacuum is less user friendly, making it more difficult to clean with this type of vacuum.

As a user pushes and pulls the vacuum to and fro, this ventilation blows away the dust on the floor in various directions, making use of this prior art vacuum less efficient.

This filter becomes clogged up over time, and the filter must be removed and emptied and / or replaced.

The size, shape and location of the dust collection bin makes removal and replacement difficult.

Further, as the filter becomes clogged, the efficiency (suction) of the motor is decreased, thereby reducing the efficiency of the motor.

Still another adverse effect of the related art steam vacuum cleaner is that when in use for steam cleaning and / or vacuum cleaning, it is highly possible that the sucked-up steam enters the motor and causes an electrical short.

This type of motor has a low cooling efficiency.

The cool air sucked into the motor and the warm air exhausted from the motor are not separated, and the motor can, at times, overheat.
