A parts washer includes a tank for holding a washing liquid. Electrically powered heating and pumping means supply heated washing liquid to a spray manifold to wash parts in an upper portion of the tank. The spray manifold is a tube of rectangular cross section, and has spray holes through an edge of the tube. A movable lid partially covers the tank top to leave a vent gap. A deflectable vapor baffle across the tank under the lid and above the spray manifold provides a releasable seal to vent vapor from the tank through the vapor gap. A horizontal plate in the tank and below the vapor baffle, and a reservoir baffle extending down from the plate enclose a reservoir space for heated washing liquid in communication with the upper portion of the tank. A control circuit supplies electric power to either the heating means or the pumping means, but not to both at the same time.

[ What is claimed is:] [1.] A parts washer comprising:a) a tank having an upright wall, a bottom, and an open top;b) a movable lid on the tank and shaped to cover most of the tank and leave a vent gap between the lid and tank wall;c) a spray manifold mounted around the interior of the tank wall and adjacent an upper portion of the tank, the manifold having a rectangular cross section with longitudinally spaced spray holes through an edge of the manifold to spray washing liquid in a spray zone in the tank;d) an electrically powered pump for pumping washing liquid from a lower portion of the tank through the manifold and out the spray holes to contact parts in the tank;e) electrically powered heater in a lower portion of the tank for heating washing liquid in the tank;f) a substantially horizontal heat retention plate disposed over most of the washing liquid in the lower portion of the tank;g) a reservoir baffle extending downwardly from the plate and into the washing liquid to enclose a reservoir space for heated washing liquid, the reservoir baffle being shaped to provide communication between the reservoir space and the upper portion of the tank;h) a deflectable vapor baffle disposed across the tank above the spray manifold to close off the interior of the tank below the vapor baffle from ambient air, the vapor baffle being spaced below the lid and constructed to release pressure from the tank in the space below the baffle;i) a switching circuit for connecting a source of electrical power to the heater and disconnecting the power from the pump, and for connecting the power to the pump and disconnecting the power from the heater;j) a switch responsive to the position of the lid for interrupting power to the heater and to the pump;k) an outwardly extending cantilevered shelf mounted to the tank to support parts; andl) a parts support in the spray zone.
