Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to an energy-saving hot air circulation rotary oven. Background Art

[0002] When baking food, a rotary oven is usually selected to bake the food. The rotary oven can rotate the food during drying, making the baking of the food more uniform.

[0003] For example, a rotary heat circulation oven with the patent number CN218389560U includes: a furnace body shell, the furnace body shell is fixedly installed on an installation platform, the air return port of a circulating hot air blower is communicated with the inside of the furnace body shell through a circulating pipeline, a chassis is fixedly installed on the inner wall of the bottom plate of the furnace body shell. The above document still has deficiencies. When in use, by arranging a rotating rack and a baking tray used in cooperation with the rotating rack inside the furnace body shell of the baking oven, putting the biscuit embryo into the embryo groove of the baking tray, and then putting the baking tray into the installation groove of the corresponding fan blade disc, driving the rotating rack to rotate through a driving motor. When the circulating hot air blower blows air into the shaft tube, the hot air enters the inside of the baking furnace body shell through the ventilation holes on the shaft tube to bake the biscuit embryo. There are ventilation holes on both sides of the fan blade plate. However, when the above-mentioned oven is in use, in order to make the hot air inside the box body flow, ventilation holes are usually arranged on the box body. But when the blowing of the hot air inside the box body stops, the heat inside the box body will be discharged through the ventilation holes, resulting in heat loss, and thus the energy-saving effect cannot be achieved. At the same time, when the motor controlling the rotation of the material box fails, the material box will not be able to rotate, which will affect the baking effect of the food.

When the first motor 6 fails, the material box 8 can continue to rotate, and thus the baking effect of the food will not be affected.

[0029] Working principle:

[0030] When baking food with an energy-saving hot air circulation rotary oven, open the door panel 12, place the food to be baked inside the material box 8, and close the door panel 12;

[0031] Food baking stage:

[0032] Start the first electric push rod 302. The first electric push rod 302 drives the support rod 303 to move. The support rod 303 drives the pin rod 304 to move. The pin rod 304 drives the cross bar 305 to move through the chute provided in the cross bar 305. The cross bar 305 drives the second support plate 306 to rotate. The second support plate 306 drives the plug block 307 to rotate. The plug block 307 separates from the through hole provided in the box body 2. Start the second motor 9, the first motor 6 and the heating grid 11. The heating grid 11 heats up. The second motor 9 drives the fan 10 to rotate. The fan 10 blows out the heat generated by the heating grid 11 and acts on the food in the material box 8. The first motor 6 drives the second rotating rod 7 to rotate. The second rotating rod 7 drives the material box 8 to rotate, so as to make the food baking more uniform. When the plug block 307 in the shielding mechanism 3 at the upper left separates from the through hole provided in the box body 2, the outside air enters the inside of the box body 2 through this through hole. The air circulates inside the box body 2 and then is discharged through this through hole to realize hot air circulation. When the plug blocks 307 in the two folding mechanisms 3 both separate from the through holes provided in the box body 2, the air enters from one through hole and is discharged from the other through hole;

[0033] Heat preservation stage:

[0034] When it is necessary to retain the heat inside the box body 2, turn off the second motor 9 and the heating grid 11, and reverse-start the first electric push rod 302. Then the plug block 307 moves in the reverse direction to block the through hole provided inside the box body 2, preventing the heat inside the box body 2 from escaping. The heat inside the box body 2 will not be discharged from the ventilation port, and no heat loss will be caused, thus achieving an energy-saving effect;

[0035] Linkage stage:

[0036] When the first motor 6 is damaged, two second electric push rods 401 are started. The two second electric push rods 401 drive the third support plate 402 to move upward. The third support plate 402 drives the cylinder 403 to move upward. The groove inside the cylinder 403 is sleeved on the outer wall of the square column 404. When the pushing device is in operation, the wheels 5 rotate. The middle wheel 5 drives the second bevel gear 407 to rotate. The second bevel gear 407 drives the first bevel gear 406 to rotate. The first bevel gear 406 drives the first rotating rod 405 to rotate. The first rotating rod 405 drives the cylinder 403 to rotate. The cylinder 403 drives the square column 404 to rotate through the groove provided inside. The square column 404 drives the second rotating rod 7 to rotate, thereby realizing the rotation of the material tray 8. When the first motor 6 fails, the material box 8 can continue to rotate, thus not affecting the baking effect of the food. After the food in the material box 8 is baked and cooled, the door panel 12 is opened. When baking, the door panel 12 isolates the interior of the box body 2 from the outside world to avoid scalding and achieve safe production.
