The present invention relates to a method and apparatus for directing steam distribution in a steam cooker. In one exemplary embodiment, steam is directed through a steam cooker by a plenum that is in fluid communication with a steam chamber. As steam is generated within the steam chamber, the steam fills the chamber where it is directed to the plenum. In one exemplary embodiment, the plenum is formed to extend vertically along an interior wall of the steam cooker. In one exemplary embodiment, the plenum is defined between an interior wall of the steam cooker and a steam distributor that has a plurality of openings formed therein. The openings in the steam distributor allow for steam rising within the plenum to exit into the cooking chamber by passing through the openings. A pressure switch may be utilized to turn off the steam generator in the steam cooker.

1. A steam cooker, comprising: a cooking chamber defined by a plurality of walls, one of said plurality of walls including a vent orifice in fluid communication with said cooking chamber and an environment external to said cooking chamber;a steam collector including a solid upper surface and a side wall, said solid upper surface and side wall defining a steam chamber;a gap defined by said side wall and at least one of said plurality of walls of said cooking chamber;a quantity of water positioned within said gap and within said steam chamber, said quantity of water flowable between said gap and said steam chamber, said quantity of water forming a water seal between said steam chamber and said cooking chamber;a plenum in fluid communication with said steam chamber; anda steam distributor having a plurality of openings formed therein, said steam distributor cooperating with at least one of said plurality of walls of said cooking chamber to define said plenum, said side wall of said steam collector extending beyond a periphery of said upper surface of said steam collector to direct steam from said steam chamber defined by said steam collector to said plenum, whereby steam only exits the steam chamber via the plenum as steam in said steam chamber is directed through said plenum and out of said plurality of openings in said steam distributor. 2. The steam cooker of claim 1, wherein said side will includes a cutout, and wherein said quantity of water is flowable between said gap and said steam chamber via said cutout in said steam collector. 3. The steam cooker of claim 1, further comprising a pressure switch in fluid communication with said cooking chamber via a pressure orifice formed in one of said plurality of walls of said cooking chamber, said pressure switch positioned in an elevated position relative to said pressure orifice, whereby said elevated position allows gravitational forces to draw any formed condensate back into said cooking chamber. 4. The steam cooker of claim 3, further comprising a first tubing and a second tubing having different diameters, said first tubing adjacent to said pressure switch and said second tubing adjacent to said cooking chamber, said first tubing and said second tubing positioned in series to each other, and said pressure switch positioned on an exterior side wall of said steam cooker. 5. The steam cooker of claim 3, wherein the pressure switch activates to turn off one or more heaters at a preset pressure level, and wherein said preset pressure level is set for a range of about 0.2 inches water column to 3 inches water column. 6. The steam cooker of claim 3, wherein the pressure switch activates to turn off one or more heaters at a preset pressure level, and wherein said preset pressure level is set for 0.5 inches water column. 7. The steam cooker of claim 1, wherein said vent orifice has a diameter in a range of about 0.10 inches to 0.5 inches. 8. The steam cooker of claim 1, wherein said vent orifice has a diameter of 0.305 inches. 9. The steam cooker of claim 1, wherein at least one of said plurality of openings has a diameter in a range of about 0.110 inches to 0.260 inches. 10. The steam cooker of claim 1, wherein said cooking chamber includes a top surface and said plurality of openings are positioned in one or more horizontal rows corresponding to a maximum usable number of pans, said one or more horizontal rows comprising a top row adjacent to said top surface of said cooking chamber, a bottom row adjacent to said steam collector, and one or more middle rows positioned intermediate to said top row and said bottom row. 11. The steam cooker of claim 10, wherein a number of said plurality of openings for each horizontal row is four openings. 12. The steam cooker of claim 1, wherein said upper surface and said side wall of said steam collector are integral. 13. The steam cooker of claim 3, wherein said pressure orifice is fluidly connected to said pressure switch by a tube that extends away from said cooking chamber and then back toward said cooking chamber to form a continuous U-shape, said elevated position of said pressure switch together with the continuous U-shape of said tube allows gravitational forces to draw any formed condensate back into said cooking chamber. 14. The steam cooker of claim 3, wherein said pressure switch is positioned on an exterior side wall of said steam cooker adjacent to said cooking chamber, whereby a quantity of heat within said cooking chamber helps to keep any steam entering said pressure switch from condensing.
