A busbar assembly is disclosed that includes a carrier, and a plurality of conductors arranged within the carrier such that at least a portion of each of the plurality of conductors are exposed in a radial direction and define electrical contact sites. The carrier can be formed by molding the carrier about the plurality of conductors.

A pressurized fluid dispenser includes a base unit and a reservoir. The base unit includes a pump and a battery compartment including electrical contacts electrically connected with the pump. The reservoir is supported by and selectively removable from the base unit. The reservoir includes an internal compartment that is in fluid communication with the pump when the reservoir is connected to the base unit. A female panel mount for an electrically operated unit is also disclosed.

Portable cleaning device

A self-propelled appliance, such as a vacuum cleaner includes a magnetic field sensor and magnet. A relative position between the magnetic field sensor and the magnet can be changed by a user of the appliance. The magnetic field sensor generates a signal indicating a magnetic field sensed by the sensor. Therefore, the magnetic field sensor signal indicates the relative position of the magnet to the sensor. This relative position signal is interpreted as a speed and direction request for a means for propelling the appliance. The magnetic filed sensor is, for example, a Hall effect sensor. The means for propelling includes, for example, a brushless d.c motor, sensorless motor or switched reluctance motor. Forward and reverse propulsion is provided without the use of a clutch. The appliance includes a reduced number of wearing components.

Electronically commutated drive system for vacuum cleaner

A self-propelled vacuum cleaner includes a base having a suction inlet. An upright housing is pivotally mounted to the base. A suction source is disposed in one of the base and the upright housing to generate an airflow at the suction inlet. A dust collection chamber is mounted to one of the base and the upright housing and communicates with the suction inlet and the suction source. A drive motor is mounted to the base. A driven wheel is operatively connected to the drive motor. A handle assembly is mounted to the upright housing, wherein the handle assembly includes an upper handle, a handle grip assembly slidably mounted to the upper handle, and a neutral return spring fastened to the upper handle and engaging the handle grip assembly to urge the handle grip assembly to a neutral position.

A self-propelled appliance comprises a base, electric motor mounting the base, a handle moveably depending from the base and a drive wheel mounted in the base and operatively connected to the motor. The control circuits comprising an enable switch and a base switch control the communication of power from the power supply to the motor relative to a gripping of the handle by a user of the appliance and a selective positioning of the handle relative to the base.

A blower fan assembly for removing combusted by-products and flue gas from a furnace is presented. The blower fan assembly includes a housing with a cavity for receiving a blower fan. The housing is secured over an opening in a furnace so that when the blower fan rotates, flue gas is drawn from the furnace to an exhaust conduit outside the building in which the furnace is received. The blower fan includes a fan ring connected to a fan disc by a plurality of vanes which are parallel with the axis of rotation. A motor, mounted to the housing, rotates the fan disc. The blower fan draws air in through the fan ring, through the plurality of vanes and out through the exhaust conduit. A static pressure tap is located in the housing and is connected to a pressure sensor which measures the static pressure generated by the blower fan as it rotates. By employing a plurality of pressure openings in the fan disc, a predictable range of static pressures can be generated within the cavity which allows the pressure sensor to monitor whether the blower fan assembly is working properly. Thus, if the pressure sensor determines that the blower fan is not working, the furnace is turned off. This precludes generation of flue gas that might accumulate in the building receiving the furnace. By adjusting the number of pressure openings, the blower fan assembly can be designed so that the static pressure tap is in only one location and does not have to be placed in different locations for each particular use of the blower fan assembly with a particular furnace.

Blower for generating static pressure

A blower fan assembly is provided which includes a blower housing, an exhaust port having an air passage connected to the housing and an impeller assembly rotatably received within the housing. A sound attenuator is also provided to be received in the exhaust port. The attenuator includes at least one edge which extends into the housing to provide a gradual cutoff point. Air moving ahead of the rotating impeller vanes is partially redirected through the exhaust port by the attenuator. Remaining air is directed over and around the attenuator and is forced out of the housing at the cutoff point created where the exhaust port joins the housing. The redirection of air alleviates compression/decompression at the cutoffs thereby reducing the pulsing noise associated therewith.

An exhaust fan assembly for implementation with a hot water tank. The assembly includes a generally elliptical housing having a large end maintaining a fan and a smaller opposite end having an exhaust port. The fan is rotatable about a vertical axis and is positioned to be maintained over the exhaust vent of a hot water tank. The configuration of the housing as such is to be received between the inlet and outlet pipes of the hot water tank. A motor cup is press fit onto a lid which is formed as a portion of the housing on a top portion thereof, while a cover plate is press fit or snap fit into a circumferential flange about a bottom portion of the housing. The cover plate has an aperture therein in alignment with the fan to allow the fan to communicate with the flue pipe of the hot water tank. The cover plate and housing define a cavity within which the fan rotates, while further defining a path for movement of the exhaust gases and motor venting air to the exhaust port. The exhaust port and motor and fan axes are vertical and parallel to each other. A cylinder defined by the fan and a cylinder defined by the tubular exhaust port are preferrably parallel and non-intersecting.
