Abstract:
A door safety latch for air cleaner is provided. The door safety latch includes a latch arm including a latch projection, with the latch arm configured to pivot with respect to a door of the air cleaner, and a slider that traps a portion of the latch arm. The slider is configured to hold the latch arm in a first, latched position and further configured to pivot the latch arm to a second, unlatched position. The door safety latch further includes a release button that includes a stop shoulder. The release button is biased to a normally extended position with the stop shoulder blocking movement of the slider and the latch arm to the second, unlatched position.
Abstract:
An airflow shaper for use in an air cleaner is provided according to an embodiment of the invention. The airflow shaper includes a body including a substantially central axis and a raised central region formed on the body. The raised central region transitions an impinging axial airflow into a substantially radial airflow or transitions an impinging radial airflow into a substantially axial airflow.

Abstract:
An air cleaner is provided according to an embodiment of the invention. The air cleaner includes a power supply, an electrostatic precipitator cell, and a door. The door closes the electrostatic precipitator cell inside the air cleaner. The air cleaner further includes a door switch that is actuated by the door when the door is substantially closed. The air cleaner further includes a cell presence switch. The electrostatic precipitator cell actuates the cell presence switch when the electrostatic precipitator cell is at least partially inserted into the air cleaner. The cell presence switch and the door switch enable electrical power to be supplied from the power source to one or more air cleaner components when the electrostatic precipitator cell is at least partially inserted into the air cleaner and when the door is substantially closed.
Abstract:
A retainer for use with a corona ground element of an electrostatic precipitator is provided according to an embodiment of the invention. The retainer includes a body and a retainer aperture extending at least partially through the body and adapted to receive a projection extending from the corona ground element. The retainer aperture is configured to receive the projection as a press fit.
Abstract:
A vacuum cleaner base having a volute air outlet and a beater bar housing that are substantially collinear is described. In some embodiments, the beater bar housing includes an air outlet, the volute includes a volute air inlet disposed parallel to the beater bar housing, and a volute air outlet disposed orthogonal to the beater bar housing, and an air duct connecting the volute air inlet and the air outlet of the beater bar housing; wherein the air outlet of the beater bar housing and the volute air outlet are substantially collinear. Additionally a vacuum cleaner comprising a unibody mount bracket is described. In some embodiments, the unibody mount bracket includes one or more handle receptacles, a dirty air outlet configured to receive a dirty air conduit, and a pivot joint disposed adjacent the dirty air outlet, wherein the pivot joint is configured to receive a bag mounting member.
Abstract:
