The present invention relates to a floor standing treatment device that has a front panel and a mainframe assembly adapted to be removably attachable to the front panel. The mainframe assembly has an integrally molded latching mechanism having a latch and one or more L shaped guides configured to cooperate with one or more pairs stops for limiting lateral movement of the latch. The latch is adapted to engage a portion of the front panel for securely attaching the front panel to the mainframe assembly. The air purifier may also have a cavity positioned along a bottom edge of a back housing to house an electrical cord provided with the air purifier. Additionally, the air purifier may also have an elongated slot positioned at the apex of the mainframe assembly for allowing one or two handed carrying of the air purifier.

Floor standing treatment device

The present invention relates to a floor standing treatment device that has a mainframe assembly and a back housing removably attachable to the mainframe assembly. The mainframe assembly comprises a fan and a fan scroll through which air is directed. The back housing comprises a one or more side walls wherein a portion of at least one of the sides wall is operable as an extension of the fan scroll. The device may also have a front panel having louvers being adapted to allow optimized air flow into the device.

A wash basket alignment system for an automatic washing machine having a wash basket with a drive block partially inserted through a central aperture in the bottom wall of the wash plate. A spin drive tube extends longitudinally through the central aperture in the drive block and through the wash plate bottom wall. A hold down nut is threadingly engaged to the drive block from the inside chamber of the wash basket to position the wash basket within the wash tub. Concentric alignment of the wash basket along a central longitudinal axis decreases basket runout. Therefore, the drive block has a spherical outside surface where it abuts the conical shaped outer surface of the wash basket. The radius of the spherical outside surface intersects the central axis at a point. This configuration facilitates the sliding or moving of this juncture from a first position out of concentricity to a second position that is concentric about the longitudinal axis. Additionally, the hold down nut has a conical shaped underside surface where it abuts the spherical shaped inner surface of the wash basket. A normal taken at this abutment passes through the same point on the central axis. This configuration facilitates movement from a first position out of concentricity to a second position with the wash basket concentric about the longitudinal axis. These two junctures are maintained by tightening the hold down nut.

Spherical surface drive block for washing machine basket

A gas valve assembly for forming a plurality of valves is provided which includes a unitary valve body having a gas supply passage interconnected to a plurality of flow control chambers wherein the gas supply passage is interconnected with a supply of gas. A plurality of valve plugs corresponding in number to the number of flow control chambers are provided wherein each of the valve plugs is rotatably disposed in one of the flow control chambers. A plurality of gear train assemblies operate for rotating the valve plugs within the flow control chambers. A valve cover encloses the plurality of gear trains and mounts to the valve body. A plurality of motors, secured to the valve cover, operate to rotate the valve plugs within the flow control chambers, wherein the plurality of flow control chambers and corresponding valve plugs form a plurality of valves provided in a single valve body.
