6. A heat convection roaster as set forth in claim 5 wherein the crown is cylindrical and a pair of said deflector inlets and a pair of said deflector outlets are symmetrically disposed about a circumference of the crown, wherein the pair of said deflector inlets are oppositely disposed and the pair of said deflector outlets are oppositely disposed.
7. A heat convection roaster as claimed in claim 5 further comprising a deflector channel cooperating with the deflector outlet, the deflector channel being disposed at the bottom of the food container and enclosing around the outlet to direct the air flow exiting the outlet into the first region of the deflector space remote from the inlet.
8. A heat convection roaster as claimed in claim 7 wherein the start of the diversion trench is fitted to the wall of the dome, the end of the diversion trench is formed with an upper outlet near the wall of the food container, the top of the diversion trench is fitted to the bottom of the tray, the bottom of the diversion trench is fitted to the bottom of the food container, the air flow horizontally flowing out of the outlet passes through the start, end and upper outlet of the diversion trench in sequence and flows upward from the upper outlet to the wall of the food container.
9. A heat convection roasting appliance as set forth in claim 8 wherein the side walls of said deflector channel, the bottom of said plate, the bottom of said food container, the walls of said food container and the walls of said dome collectively define said second region of said deflector space which directs the air flow returning from said plate to said inlet opening.
10. A heat convection roaster as claimed in claim 8 wherein the food container bottom aperture is peripherally provided with an anti-spill rim which, together with the food container wall, the bottom of the food container, defines an annular trough for storing liquid and solid food, the deflector channel being disposed in the annular trough.
