about 4 8 oz capacity preferably mounted on the front of wall portion 18 and is conducted thru a small metal tube or line 38 such as a u215b in i d copper or stainless steel tubing this line is affixed to the inside of wall 12 and runs as shown into the open top of body 32 without contacting heating element 20 the inlet end 41 or outlet end 42 of line 38 can be pinched as desired to feed the water onto flash pan 34 at a desired rate referring to fig4 7 a much preferred steam generating body 44 preferably of tubular stainless steel pipe of e g 1 u00bd in i d and 9 in length capped at both ends is employed and is provided with holes 46 one of which connects with outlet end 42 of line 38 and the others allowing the escape of steam a bed 48 of u215b u2033 to u00bd u2033 preferably u00bc u2033 diameter stainless steel balls is positioned in the tube to provide a mass to capture sufficient heat prior to introduction of water to flash the water from the tube when needed the position of the generator as shown in fig5 within the oven cavity 49 is quite significant in that it is juxtaposed but not touching the heating element 20 so that the generator is maximally effective in absorbing radiant heat but doesn 39 t block the heating element such as to cause a cold spot in the oven referring to fig8 and 9 concerning a gas fired oven having gas burners 39 this particular embodiment 50 of the steam generator comprises a substantially vertically mounted tube 52 of about 12 in in length preferably.
