Abstract

This invention relates to an in-line and frame independent electric blower half-housing, with cylindrical walls or essentially nonparallel interior walls constructed of an elastomeric material, and which is thereby acoustically silenced and is also easily disassembled for maintenance. The blower half-housing consists of one piece. The blower half-housing was designed for use in the spa industry, as an air blower, but has applications in other industries.

Claims

1. A one-piece blower housing, suitable for housing a blower motor which blows fluids, including air, comprised of:

a. said one-piece blower housing with three openings;

     1) an intake opening to receive a portion of the blower motor such that the intake of said motor would protrude from said intake opening,

     2) an extended output opening to receive one end of the output flow piping, on the opposite end of said housing in relation to said intake opening, and

     3) an extended cable opening to receive a portion of the electric power cable which is connected to said motor,

b. a fastening means for securing and air-sealing said portion of said motor within said intake opening of said housing,

c. a fastening means for securing and air-sealing said portion of said electric power cable within said extended cable opening and said housing,

d. a fastening means for securing and air-sealing said output flow piping end within said extended output opening,

e. an output restraint notch for restraining said output flow piping end from being inserted too deep into said housing, and

f. an interior geometry of said housing, which consists of essentially nonparallel interior walls, and said walls may have a geometry which is spherical, the zone of a sphere, cylindrical, conical, the frustrum of a cone, or a combination of these geometries.

2. A blower housing, as recited in claim 1, wherein:

said fastening means are suitably fitted hose clamps, or the like for air-sealing and securing;

a. needed portion of said electric power cable within said extended cable opening and said housing,

b. needed portion of said output flow piping within said extended output opening, and

c. needed portion of said blower motor within said intake opening and said housing.

3. A blower housing, as recited in claim 2, wherein said hose clamp or the like for setting and securing a portion of said motor within said housing is further set and secured in place with:

a. a male housing restraint notch, which is located on the edge and around the external perimeter of said intake opening.

4. A blower housing, as recited in claim 3, wherein said hose clamps or the like are further set and secured in place with:

a. an indented housing fitting around the external surface of said housing and adjacent to said mate housing restraint notch, for setting and securing said hose clamp around external perimeter of said intake opening, and

b. an indented output fitting area near said extended output opening, for setting and securing said hose clamp or the like around the external perimeter of said extended output opening.

5. A blower housing, as recited in claim 1, wherein said housing is composed of a material selected from the group of materials known as polymeric or elastomeric materials.

6. A blower housing, as recited in claim 4, wherein said housing is composed of a material known as neoprene, and which is between 60 and 70 Shore in hardness.

7. A one-piece blower housing, suitable for housing a motor which blows fluids, comprised

a. said one-piece blower housing with openings to:

1) receive a portion of the blower motor such that the intake of said motor would protrude from said housing,

     2) receive one end of the output flow piping, on the opposite end of said housing in relation to the location of the motor'"'"'s protruding intake end, and

     3) receive a portion of the electric power cable which is connected to said motor,

b. a fastening means for securing a portion of said motor within said housing,

c. a fastening means for securing said portion of said electric power cable within said housing,

d. a fastening means for securing said portion of said output flow piping end within said housing, and

e. an interior geometry of said housing, which consists of essentially nonparallel interior walls, and said walls may have a geometry which is spherical, the zone of a sphere, cylindrical, conical, the frustrum of a cone, or a combination of these geometries.

8. A blower housing, as recited in claim 7, wherein said fastening means are hose clamps or the like.

9. A blower housing, as recited in claim 7, wherein said housing is composed of a material selected from the group materials known as polymeric or elastomeric materials.

10. A blower housing, as recited in claim 7, wherein said housing is composed of a material known as neoprene, and which is between 60 and 70 Shore in hardness.

11. A blower housing, as recited in claim 7, wherein there is an output restraint notch for restraining said output flow piping from being inserted too deep into said housing.

12. A blower housing, as recited in claim 7, wherein said fastening means for securing a portion of said motor within said housing is further secured in place with a male housing restraint notch, which is located on the edge and around the external perimeter of the intake opening of said housing.

13. A blower housing, as recited in claim 8, wherein said hose clamps are further secured in place with 1) an indented housing fitting around the external surface of said housing, for further securing the hose clamp around the external perimeter of said housing'"'"'s intake opening, and 2) an indented output fitting area near the extended output opening, for further securing the hose clamp around the external perimeter of said extended output opening.
