Abstract
A housing for a fan motor for a portable paint spray gun has a compartment accessible from the bottom in which an air hose is storable and provides an air path from the fan motor to the air hose having a minimum number of turns or curves between the motor exhaust port and the air hose. The housing enhances portability by providing convenient storage for the air hose when not in use and increases fan motor efficiency by reducing drag on the air flow by providing a relatively low resistance air path from the fan motor to the air hose.
Claims19
An improved air flow structure for a portable painting apparatus comprising:
- a) a fan motor assembly having an air outlet delivering air generally axially along an axis of the motor as the air exits the fan motor assembly;
- b) a cover disposed over the air outlet of the fan motor assembly, the cover defining a generally rectangular air plenum having a pair of elongated side walls and a pair of short end walls at the air outlet, an arched top wall, and a circular air exit aperture in one of the end walls of the rectangular air plenum such that air exiting the fan motor assembly passes immediately into the air plenum and exits the plenum at substantially a right angle to the motor axis.
A hose storage apparatus for portable painting equipment comprising:
- a) a hollow fan motor housing having a generally oval vertical cross section and an opening on the bottom thereof;
- and
- b) a bottom cover releasable securable to the bottom of the housing to close the opening
- wherein an air hose is storable in the hollow fan motor housing and is retained therein when the bottom cover is secured to the housing.
A fan motor housing for a portable painting apparatus comprising:
- a generally hollow elongated housing body, having an upper surface, the upper surface having a first depression, the first depression adapted and designed to contain a fan motor the first depression having venting means to allow entry of air into the first depression;
- b) an inner dome disposed over the first depression and affixed with substantially air-tight means to the elongate housing body for preventing escape of air therebetween, the inner dome having a generally vertical portion defining a circular opening;
- c) a generally cylindrical fitting defining a passage communicating between an interior end and an exterior end of the fitting, the fitting having a slightly tapered cylindrical section disposed at the interior end of the fitting, the interior end of the fitting having a smooth surface adapted and designed to fit with a substantially air-tight seal within the opening of the inner dome;
- and
- d) an outer dome disposed and affixed over the inner dome, the outer dome defining a bore aligned with the circular opening of the inner dome, the bore adapted and designed to retain the cylindrical fitting with the interior end of the fitting positioned within the circular opening of the inner dome;
- such that air flow exiting the fan motor is directed into the inner dome and then out through the passage of the fitting.
