  • Motor ventilation system for wet/dry vacuum cleaner
    Patent number: 4114231
    Abstract: This invention relates to an air flow system for a vacuum cleaner which, because of the nature of the machine, must be able to operate in wet or damp environments without the ingestion of water into the motor. The housing for the motor is of a bulbous shape manufactured of an insulating material and is arranged to have a bulbous shaped insulating cap fitted on the housing in a spaced apart relationship, such that two air flow channels are produced between the housing and cap by a pair of rib structures integrally cast in said housing structure. Air is drawn into the bottom of the cap and moves upwardly between housing and cap, passes through the housing and through the motor fan, through the motor to provide the necessary cooling and thence is expelled to atmosphere by passage out of ports in the housing to pass into another section of the housing-cap structure.
