Abstract

An anti-splash, non-contaminating scrub sink is provided wherein a zone in the bottom of the sink including the drain is perforate and a reduced pressure is maintained below the perforate zone to draw the scrub fluid from the sink. In one embodiment the perforate zone includes the entire bottom and a portion of the side walls of a liner for the sink.

Claims

1. A personnel scrub sink comprising sidewalls, a bottom wall, a scrub fluid drain in the bottom wall connected to conventional fluid disposal means and a shower head connected to a source of scrub fluid via flow control valves characterized in that at least a portion of the bottom wall including the drain portion is perforate, a chamber below the perforate zone, a vacuum pump, conduit means connecting the low pressure side of the vacuum pump and the chamber, and further conduit means connecting the pressure side of the vacuum pump and an area remote from the scrub sink.

2. The invention defined in claim 1 wherein said conduit means connecting the low pressure side of the vacuum pump and the chamber and the scrub sink drain comprise at least in part a common conduit.

3. The invention defined in claim 1 wherein the conduit means connecting the low pressure side of the vacuum pump and the chamber is separate from the drain for liquid from the chamber.

4. The invention defined in claim 1 wherein at least a portion of the side walls, front wall and back wall are provided with spaced perforate inner walls and the space between said inner walls and said side walls, back wall and front wall are in fluid communication with the chamber connected to the low pressure side of the vacuum pump.

5.
