Vacuum cleaner attachment storage in recesses beneath a floor supported vacuum cleaner housing with pivoted latch elements for attachment retention which does not require increased cleaner housing dimensions or a cover for the stored attachments, either to conceal the stored attachments or to prevent dirt collection in the storage recesses.

Vacuum cleaner tool storage

A latch device for a filter bag supporting tray comprising a plurality of latch bolts operatively interrelated to move together so that blockage of any latch bolt will result in prevention of any other bolt from entering its latch recess, and only secure fully latched constraint of the tray is possible.

Dirt drawer latch for vacuum cleaner

A floor care appliance having a filter bag with an inlet chamber accessed by an inlet aperture, and a quiescent storage chamber connected to the inlet chamber by an opening adjacent the top thereof. The filter bag is formed of filter sheet material as an elongate tubular member having the opposite ends folded and sealed to define an air impermeable seal. An inlet aperture extends into the interior of the tubular member adjacent one end thereof and the tubular member is folded upon itself spaced from the other end thereof with confronting portions of the tubular member being sealed together and including an opening adjacent the fold between the confronting portions to maintain an open air path from the inlet aperture to the other end of the filter bag. The inlet aperture is located so as to create an air flow in the inlet chamber which is curved adjacent the opening between the confronting portions of the tubular member, so that the heavier dirt particles are encouraged to flow through this opening to the storage chamber thus formed for the dirt particles outside of the air flow for the floor care appliance.

Filter bag for floor care appliance

A floor care appliance having a main housing with a handle extending from an upper portion thereof, and having a motor blower assembly affixed thereto with an inlet tube extending from a lower portion thereof. The main housing is fashioned with a rearwardly open cavity portion for receiving a filter arrangement including a paper filter bag having connection to an outlet tube of the motor blower assembly, and a second stage of filtration implemented by an air permeable closure covering the rearwardly open cavity portion. A floor unit carries a brush actuated by a reversible motor, a dry chemical carpet cleaning powder receptacle and dispensing arrangement for selectively dispensing the powder adjacent the brush, and a plenum chamber extending from adjacent the brush to a swivel having an outlet tube connected and affixed to the inlet tube of the motor blower assembly. A switch assembly is carried by a cover for the main housing and provides for operator selection of one of several modes of operation. A switch device is also provided to selectively actuate the dispensing arrangement during a specific one of the several modes.

Floor care appliance

A power head unit for use with an external source of vacuum, which unit includes an outer housing defining a brush chamber, a vacuum chamber and a dry chemical carpet cleaning powder retaining chamber. The powder retaining chamber is fashioned with at least one slot extending adjacent the brush chamber which slot is closed off by a covering device such as a sliding door. The sliding door is fashioned with apertures the size of the at least one slot so that correspondence thereof will permit the dry chemical carpet cleaning material to escape from the slot. A powder dispensing roll is provided internally of the powder retaining chamber to convey the dry chemical carpet cleaning material to the slot. The power head device may be utilized in a vacuum mode of operation as a vacuum cleaner, or in a cleaning mode of operation as a carpet cleaner, in which latter mode provision may be made to separate the source of vacuum from the vacuum chamber so as to permit the dry chemical carpet cleaning powder to be thoroughly mixed in the rug fibers without removal thereof. The powder retaining chamber may be fashioned of translucent material and a light source situated adjacent the same so as to facilitate the determination of the quantity of powder remaining in the powder retaining chamber.
