Abstract
An exemplary embodiment of an air blower includes an electrically powered motor including a motor housing. A blower housing has first and second housing structures, each having inwardly facing, spaced ribs, and configured to surround the motor assembly in an assembled configuration. The ribs on the first and second housing structures register the radial and axial position of the motor housing inside the housing.
Claims12
An air blower comprising:
- an electrically powered motor and impeller assembly including a motor housing;
- a blower housing comprising first and second housing structures, each having inwardly facing, spaced ribs, and configured to support the electrically powered motor and impeller assembly in an assembled configuration;
- a sealing gasket including a flange portion captured between respective mating flange surfaces of the first and second housing structures and a tubular gasket portion extending into the second housing structure, into which the motor housing is fitted;
- the inwardly facing, spaced ribs of each of the first and second housing structures configured to determine the radial and axial position of the motor housing inside the blower housing, with the sealing gasket providing sealing between the first and second housing structures;
- and
- wherein the tubular gasket portion has a longitudinal length to extend past the motor housing and has a plurality of slots formed at a distal end, and wherein the inwardly facing, spaced ribs of the second housing structure are configured to contact the tubular gasket portion of the sealing gasket to roll the distal end of the sealing gasket over an end of the motor housing.

An air blower comprising:
- an electrically powered motor assembly including a motor housing;
- a blower housing comprising first and second housing structures, each having inwardly facing, spaced ribs, and configured to support the motor assembly in an assembled configuration;
- the first housing structure configured as a pressure side of the blower with an outlet port through which pressurized air is delivered by the blower under operating conditions, the second housing structure configured as an inlet side of the blower through which air is drawn by action of the motor assembly;
- a sealing gasket defining an inner opening and a tubular gasket portion sized to receive the motor housing in a tight fit, the sealing gasket further including a flange portion captured between respective mating flange surfaces of the first and second housing structures;
- the inwardly facing, spaced ribs of each of the first and second housing structures configured to determine the radial and axial position of the motor housing inside the blower housing, with the sealing gasket providing sealing between the first and second housing structures;
- and
- wherein the electrically powered motor assembly is secured in position within the blower housing and within the inner opening and tubular gasket portion of the sealing gasket by cooperative engagement of the electrically powered motor assembly with said inwardly facing, spaced ribs of each of the first and second housing structures and said sealing gasket, without the use of separate clamps or fasteners;
- and
- wherein the tubular gasket portion has a longitudinal length to extend past the motor housing and has a plurality of slots formed at a distal end, and wherein the inwardly facing, spaced ribs of the second housing structure are configured to contact the tubular gasket portion of the sealing gasket to roll the distal end of the sealing gasket over an end of the motor housing.
