Abstract
A dryer with a modular blower assembly that allows easy assembly and field servicing through replacement of the blower assembly as a unit. The blower assembly generally includes unique motor mounts that allow a motor assembly to be secured within a housing without being directly fastened to other members.
Claims31
A blower assembly for a dryer assembly configured to dry hands, said blower assembly comprising:
- a blower housing having a base and an outer wall collectively defining a blower cavity with a blower cavity diameter, and wherein said blower cavity is substantially aligned along on operational axis, and wherein said housing includes at least one air inlet;
- a motor mount having a motor mount diameter and wherein said motor mount is configured to be received in said blower cavity and includes at least one Helmholtz resonator;
- and
- a motor assembly including a motor and a blower and wherein said motor and blower are at least partially enclosed in an outer casing having an air inlet and an air outlet and wherein said outer casing sealingly engages said motor mount between said air outlet and said air inlet.
