Abstract: A blower housing may be used with a climate control furnace or with a water heater and provides cooling of the motor that rotates the blower fan and also provides dilution and cooling of exhaust gases drawn from the furnace or water heater. The housing has an interior dilution compartment that communicates with an elongate conduit. The dilution compartment receives dilution air through the conduit, thereby reducing blower operation noise at the blower housing.

Abstract: A blower housing may be used with a climate control furnace or with a water heater and provides cooling of the motor that rotates the blower fan and also provides dilution and cooling of exhaust gases drawn from the furnace or water heater. The housing is constructed with one side that is positioned in a single plane that is easily mounted to a flat surface of the furnace or water heater and can be sealed against the surface. The housing is provided with an interior heat shield that insulates the exterior surface of the housing and with a noise muffler.

Abstract: A furnace blower apparatus has a tubular housing that is connected between a heating furnace and an exhaust flue of the furnace. The housing has an interior bore containing a fan assembly for drawing air through the furnace burner chamber on operation of the fan assembly. The housing includes a panel that is removably mounted to a side wall of the housing. The fan assembly is mounted to an interior surface of the panel, whereby the fan assembly can be removed from the interior of the housing by removing the panel from the housing.

Abstract: A blower for a high efficiency furnace is provided with an increased interior space for accommodating an impeller of maximum practicable diameter. The blower includes a blower motor and a blower housing having a bottom piece and a top piece assembling with the bottom piece to define an interior of the blower housing. The top piece includes an annular lower support portion for supporting the blower motor and an annular upper portion extending above and around the lower portion. The upper portion has an outer peripheral edge and lugs extending outward beyond the outer peripheral edge. The lugs have lug holes to receive mechanical fasteners to secure the blower housing to an external device. The head of the mechanical fasteners are positioned above the lugs on the upper portion of the top piece. In this arrangement the diameter of the bottom piece is not limited by a need to accommodate spacing for the head of the mechanical fastener.

Abstract: A blower housing having a resilient bottom piece and a rigid top piece assembling with the bottom piece is provided. The top piece includes a plurality of depending legs which are urged against a matching plurality of flanges formed in the resilient bottom piece to cushion mount the top piece to a furnace or the like. A plurality of mechanical fasteners such as screws or the like extend through a plurality of lugs on the top piece and through the flanges to urge the depending legs against the flanges and the furnace. Through this construction, a generally rigid connection between the motor mounting plate and the furnace is achieved while providing the sound and vibration attenuation of a resilient housing.

Abstract: A blower for a furnace is provided with an exhaust flange having a compressible end portion, and a flexible fitting adapted to receive an exhaust pipe is insertable into an interior of the exhaust flange. A clamp compresses the compressible end portion about the flexible fitting and the exhaust pipe to secure the exhaust pipe to the blower. A drain may be provided adjacent the compressible end portion to remove condensate which may be entrained in the exhaust gases from the exhaust pipe, exhaust fitting and exhaust flange.

Abstract: A blower for a furnace is provided where the blower has a housing with an industry standard 4″ diameter exhaust port. The discharge of the blower housing is coupled directly to exhaust piping without the use of transition pieces or expender pieces.

Abstract: A blower housing having a casing with a resilient bottom piece and a rigid top piece assembling with the bottom piece to define an interior of the casing is provided. The bottom piece of the blower housing directly abuts a blower mounting surface. The top piece supports a blower motor. The bottom piece is constructed from a vibration dampening material. The top piece is constructed from a rigid material. The vibration absorbing material attenuates noise and other vibrations transmitted from the blower motor and impeller of the blower housing to the blower mounting surface and other associated structures.

Abstract: A furnace includes a main blower housed in an inlet plenum that circulates temperature controlled air through the furnace and an inducer fan that circulates combustion gases through the furnace. The inducer fan is driven by an inducer fan motor with a housing that defines a hollow interior and surrounds the motor. The inducer fan motor housing is in communication with the inlet plenum and operation of the main blower draws cooling air through the interior of the motor housing to cool the motor.

Abstract: A blower for a furnace is provided where the blower has an impeller that is configured to create a primary air flow of combustion air into the blower housing and a secondary air flow of cooling air through the blower motor. The primary air flow of combustion air into the furnace generates hot exhaust gases for a heat exchanger in the furnace. The secondary air flow cools the blower motor. The secondary air flow is mixed with the hot exhaust gases in the blower housing and cools the exhaust gases before being discharged from the blower housing.
