Rotisserie grill

A rotisserie grill comprising:

• a rotisserie grill body (1);
• an electric controller;
• a spit rod (8);
• and
• a motor,
• wherein the rotisserie grill body (1) defines a heating cavity (100) having an upper opening,
• wherein the heating cavity (100) is provided with, at a bottom portion thereof, a detachable residue receiving tray (6),
• wherein the heating cavity (100) is provided with, on both sides thereof, a pair of vertically arranged heating tubes (2) and a pair of reflecting plates (3) that reflect heat from the heating tubes (2) into the heating cavity (100),
• wherein the rotisserie grill body (1) has a plurality of air intake holes (18) at a bottom portion thereof, the plurality of air intake holes (18) leading into a cavity between vertical inner and outer plates of the rotisserie grill body (1),
• wherein the spit rod (8) includes an inserting rod (80), a handle (81), and a positioning piece (82),
• wherein the rotisserie grill body (1) is provided with a quick connector (18) on an inner plate at a front end, and a groove (16) on each of inner and outer plates at a rear end, a front end of the inserting rod is detachably connected to an output end of the motor via the quick connector (18), a rear end of the inserting rod is connected to the handle (81) and overlaps with the groove (16),
• wherein the positioning piece (82) and the handle (81) are respectively located on two sides of the inner and outer plates at the rear end of the rotisserie grill body (1) to axially limit the inserting rod (80),
• wherein the motor drives the inserting rod (8) and food thereon to rotate, and the reflecting plates (3) directly reflect the heat of the heating tubes (2) and direct the efficiency roasting mode;
• wherein the cavity between the vertical inner and outer plates of the rotisserie grill body (1) includes a hot air passage (300) close to the heating cavity (100) and the reflecting plate (3), and a cold air duct (400) close to an outer wall of the rotisserie grill body (1),
• wherein the hot air passage (300) has a plurality of backflow holes (13) on a top portion, the plurality of backflow holes (13) communicating with the heating cavity (100) so that high-temperature air in the hot air passage (300) flows back into the heating cavity (100), and the cold air duct (400) has a plurality of exhaust holes (14) on a top portion, the plurality of exhaust holes (14) communicating with outside to discharge low-temperature air in the cold air duct (400) and reduce temperature of the outer wall of the rotisserie grill body (1);
• wherein a heat insulation cavity (500) is further provided between the hot air passage (300) and the cold air duct (400), the heat insulation cavity (500) isolates the high-temperature air and the low-temperature air of the hot air passage (300) and the cold air duct (400), and the heat insulation cavity (500) is a closed cavity.
