摘要： A mounting bracket for use in association with a vacuum canister for a central vacuum system is disclosed. The mounting bracket is received within the housing of the vacuum canister and thereby divides the canister into clean and dirt collection chambers. Dirt collection chamber is adapted to receive dirt-laden air from the central vacuum system while clean chamber is adapted to re-circulate cleaned air back into the building. Mounting bracket is preferably a molded structure having a central bore. A plurality of stepped grooves are provided for receiving one of a variety of sizes of motor therein. A plurality of circuit board brackets are formed on mounting bracket, said circuit board brackets range in size so as to accommodate a range of sizes of circuit boards therein. Mounting bracket further includes a filter support formed therein. The filter support includes a quick attachment/release mechanism for installing filters thereon. Mounting bracket also includes an aperture and straight tube connection for connecting a clean chamber auxiliary intake valve assembly to the dirt collection chamber of the vacuum canister.

摘要： A vacuum hose storage system includes a housing which is mounted in a storage area of a dwelling or vehicle and connected to a vacuum source. A length of flexible, expandable cleaning hose is mounted in a looped fashion about a plurality of spaced rollers rotatably mounted within the housing. A handle is attached to one end of the hose and is seated in a cradle formed in the housing when the hose is in a fully retracted position within the housing. The cradle is mounted in the housing and receives the open end of the hose when not in use and enables other vacuum tubes in the structure to be operational without shutting off the vacuum to the stored hose. An ON/OFF switch is located in the cradle for controlling the vacuum source and is actuated when the handle is placed in or removed from the cradle. The hose has an internal helical spring which biases the hose toward a retracted position about the spaced rollers within the housing.

摘要： A vacuum canister for use with a central vacuum system is disclosed. The vacuum canister includes a hollow, tubular housing that has openings at either end. A cover covers the upper opening and a dust collection bin is disposed beneath the lower opening. The housing is divided into clean and dirt collection chambers by a wall. The clean chamber is a dust-free area and the vacuum pump assembly is mounted therein. The dirt collection chamber is the area in the canister where the dirt-laden vacuumed air is drawn into the device. The vacuum canister is provided with an auxiliary vacuum intake assembly that enters the housing in the clean, dust-free chamber. The intake assembly includes a receptacle for receiving the end fitting of a portable vacuum hose and the receptacle is operatively connected to the dirt collection chamber of the housing by way of a conduit that extends from the receptacle through an aperture in the wall and into the dirt collection chamber. The receptacle is wired to the motor for the vacuum pump assembly so that when the portable hose is attached to the receptacle, the vacuum pump is automatically started. The wiring for the receptacle passes through the clean chamber of the housing. The receptacle includes a pivoted cover which covers the receptacle when it is not in use so as to maintain the vacuum within the system.

摘要： A power unit for an in-wall vacuum cleaning system has a first compartment which contains a motor for producing a vacuum at remote wand receptacles and a second compartment for separating and collecting the debris. An improved sound reducer is mounted in the motor compartment for reducing the sound level emitted by the motor and providing good cooling airflow for the motor. The sound reducer includes a disc-shaped base having a central opening for receiving a portion of the motor and a pair of partitions mounted on the base and forming a plurality of irregularly-shaped sound passages for breaking up the sound waves traveling therethrough. The base and partitions are formed of an acoustic foam which assist in absorbing the sound waves.

摘要： A central vacuum cleaning system includes an inlet valve mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends from the inlet valve for cleaning an adjacent area. A pair of seals within the inlet valve retains a nozzle handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on one embodiment of the inlet valves automatically locks the hose in a selected extended position when manually pulled from the inlet valve. A mounting bracket enables the inlet valve to be mounted at various locations in the structure and a pair of seals enables the inlet valve to be open to the ambient atmosphere.
