Abstract

An air blower for use in building heating systems which is designed to isolate noise and vibration from the building structure. The blower is further designed to allow for easy assembly and replacement of parts while installed in the building structure. The blower includes a housing which is mounted directly to the frame of the building. A fan wheel and motor assembly is positioned into the housing as a unit. The motor and fan assembly is supported by means of a flexible support system on the housing which isolates vibration and noise transmission. A Venturi plate is also suspended from the flexible support system and is otherwise isolated from the housing.

Claims

1. An air blower comprising a housing assembly;

mounting posts extending from said housing assembly;

an impeller positioned within said housing assembly;

a motor operably coupled with said impeller;

extended support means for supporting said motor, said extended support means extending outwardly from said motor to said mounting posts;

mounting blocks slidably positioned on said mounting posts and supporting said extended support means;

springs positioned about said mounting posts and supporting said mounting blocks; and

a Venturi plate suspended from said support means.

2. The air blower of claim 1 wherein said Venturi plate is displaced from said housing assembly.

3. The air blower of claim 1 wherein said mounting blocks are made of soft resilient material.

4. The air blower of claim 1 wherein said springs are coil springs.

5. An air blower comprising a housing assembly;

mounting posts extending from said housing assembly;

an impeller positioned within said housing assembly;

a motor operably coupled with said impeller;

extended support means for supporting said motor, said extended support means extending outwardly from said motor to said mounting posts;

mounting blocks slidably positioned on said mounting posts and supporting said extended support means;

said mounting blocks each including a collar, an upper end and a lower end, said extended support means being positioned about said upper end on one side of said collar and said springs being positioned about said lower end on a second side of said collar; and

springs positioned about said mounting posts and supporting said mounting blocks.

6. The air blower of claim 5 wherein said mounting blocks include holes through which said mounting posts extend, said holes having larger diameters than said mounting posts.

7. An air blower comprising a housing assembly including a volute, a cover and a hole extending through said cover into said volute;

mounting posts positioned about said hole;

an impeller positioned within and spaced from said housing assembly;

a motor coupled with and supporting said impeller;

extended supports attached to said motor and extending outwardly to said mounting posts;

mounting blocks slidably positioned on said mounting posts and supporting said extended supports, said mounting blocks being of soft resilient material;

coil springs positioned about said mounting posts and supporting said mounting blocks; and

said mounting blocks each including a collar, an upper end and a lower end, said extended support being positioned about said upper ends on one side of said collars and said coil springs being positioned about said lower ends on a second side of said collars, said mounting blocks further including holes through which said mounting posts extend, said holes having larger diameters than said mounting posts.

8. The air blower of claim 7 further comprising a Venturi pLate suspended from said extended supports, said Venturi plate being displaced from said housing assembly and extending to define an inlet to the center of said impeller.
