Abstract: A knob assembly for a gas cooktop is provided that includes a receptacle mounted between a valve and a knob. The knob directly mounts to a knob control rod and is configured to mount in a vertical plane perpendicular to a plane defined by a horizontal support surface for a cooking receptacle. The receptacle includes a receptacle abutment wall, a receptacle wall extending from the receptacle abutment wall, and a control rod aperture wall formed through the receptacle abutment wall. The control rod aperture wall is sized and positioned to support insertion of the knob control rod therethrough. The receptacle abutment wall is configured to abut a back of a control panel when the knob assembly is mounted to the control panel. The receptacle wall is sized and positioned within a knob aperture wall formed through the control panel when the knob assembly is mounted to the control panel.

Abstract: A chimney assembly includes a cone assembly and a chimney. The cone assembly includes a wall forming a truncated cone having an outer surface, a first circumferential edge, and a second circumferential edge, a support flange extending from the outer surface, and a bottom wall extending between the second circumferential edge and including a burner aperture wall formed therethrough. The chimney includes an inner wall, an outer wall circumscribing the inner wall, a bottom chimney wall, and a plurality of tabs. The bottom chimney wall extends between a first cylinder formed by the inner wall and a second cylinder formed by the outer wall. The plurality of tabs extend from the inner wall toward a center of the first cylinder. The support flange rests on the plurality of tabs.

Abstract: A liquid filtration system includes a sump screen, a filter, and a cap. The sump screen mounts to a tub bottom wall and includes a plate and a filter aperture edge mounted through the plate. The plate includes a sump mesh having a sump mesh size of less than approximately 0.1 inches. The filter mounts to the filter aperture edge and includes a sidewall and a plurality of posts mounted to extend up from the sidewall. The sidewall includes a filter mesh having a filter mesh size of less than approximately 0.1 inches. At least a portion of each post extends above the filter aperture edge when the filter is mounted to the filter aperture edge. The cap mounts above the plurality of posts. The plurality of posts and the cap form a conduit sized to allow material that cannot pass through the sump mesh to flow through the conduit.

Abstract: A docking system includes basket and wall conduit systems. The basket conduit system includes a conduit and first and second nozzles mounted to opposite ends of the conduit. The second nozzle has a first funnel shape with a first circumference that decreases from an open end of the second nozzle towards the conduit. The wall conduit system includes front and back housings, a sliding plate, and a third nozzle. A sliding aperture is formed through a front plate of the front housing. A nozzle aperture is formed through a back plate of the back housing. The sliding plate slides within a space formed by the front housing and the back housing. The third nozzle is sized and shaped to slide within the sliding aperture and includes a generally cylindrical shape and a second funnel shape with a second circumference that decreases from the sliding plate towards the generally cylindrical shape.
