Generally, when the barbecue food is baked on one side for a certain period of time, the rotary motor 224 rotates the fork 225 to turn over the barbecue food, the barbecue food just turned over is relatively raw and needs to be closer to the heating portion 12 to heat the uncooked surface rapidly, and as the barbecue time gradually increases, in order to prevent the uncooked surface from being burnt and aged due to high temperature, the height of the fixing portion 237 is adjusted to make the barbecue food gradually away from the heating portion 12, so as to prevent the temperature from being too high until the barbecue food is turned over again under the condition of ensuring normal barbecue of the barbecue food. Specifically, the process of increasing the height of the fixing portion 237 is a process of roasting the roasted food material, and the process of decreasing the height of the fixing portion 237 is a process of turning over the roasted food material.

Similarly, for barbecue mechanism 2, another kind of using-way is to the great barbecue food material of partial surface area, need right the barbecue food material adopts the mode of the barbecue of rolling, promptly the barbecue food material is in slow rotation state all the time, but because the barbecue eats the material surface area the reason, if fixed part 237 is highly lower, barbecue eat the material easily with arc graticule mesh 13 touches, through the rotating part with the cooperation setting of fixed part 237 when the barbecue food material rotates to the vertical setting of surface area, fixed part 237 is highly highest, avoids the barbecue food material with the touching of arc graticule mesh 13, works as when the barbecue is eaten the material surface area slope level and is placed, fixed part 237 is highly minimum, heating portion 12 can realize right the effective barbecue of material surface area is eaten to the barbecue.

Generally, for the wavy arc surface of the lower end surface of the guide plate 230, the end point of the roller 229, which initially contacts the lower end surface of the guide plate 230, should be the highest point of the lower end surface, so as to facilitate smooth contact and pressing of the roller 229 by the guide plate 230. Establishing a coordinate system by using the initial contact end of the guide plate 230, wherein the initial contact end point of the lower end surface of the guide plate 230 is an original point, the vertical upward direction is a Y-axis, the moving direction of the fixed group 22 at the upper part of the rolling frame 21 is an X-axis, and for the barbecue food materials with large surface area, the curve formula of the lower end surface of the guide plate 230 is as follows;

wherein x is the abscissa of a point on the lower end surface of the guide plate 230; y is the ordinate of the point on the lower end surface of the guide plate 230; a is the width size of the barbecue food material; θ is the angle of the fork 225 from the horizontal; r is the headblock 24 radius; n is₁For said brake wheel 24 speed；n₂The rotational speed of the rotation motor 224.

The width dimension a of the roast food material is the maximum distance dimension between the two edges of the roast food material in the direction perpendicular to the fixing rod after the roast food material is inserted on the fork 225; the curve of the lower end surface of the guide plate 230 gradually converges with the increase of the width dimension a of the barbecue food material, that is, the height difference between the highest end and the lowest end of the height of the fixing portion 237 becomes large, and the curve of the lower end surface of the guide plate 230 is in a converging state; with the speed n of the brake wheel 24₁And is continuously expanding.

Through the setting of the curve formula of terminal surface under the deflector 230, when guaranteeing to eat the barbecue that rolls repeatedly to the great barbecue of surface area, reduce the barbecue eat the material with the touching of arc graticule mesh 13 is avoided promptly arc graticule mesh 13 etc. go up the contact of carbon black gravy etc. and the barbecue eat the material, improve the security of material is eaten to the barbecue.

Example eight

The use method of the intelligent barbecue oven specifically comprises the following steps:

s1, inserting the barbecue food material on the fork 225, and the heating part 12 turning on the heating;

s2, turning on the rotation motor 224 and the brake wheel 24, and adjusting the rotation speed of the rotation motor 224 and the brake wheel 24;

s3, fixing the fork 225 on the fixed group 22 at the barbecue starting position;

s4, turning on the fan 34 and the cooling tank 373, and adjusting and fixing the diversion plate 36;

s5, the fixing group 22 fixed with the fork 225 is heated by the heating part 12 by the brake wheel 24 to the roasting completion position, thereby completing roasting.

For step S2, the rotation speeds of the rotation motor 224 and the brake wheel 24 are relatively adjusted according to different conditions; generally, when the barbecue food is baked on one side for a certain period of time, the rotary motor 224 rotates the fork 225 to turn over the barbecue food, the barbecue food just turned over is relatively raw and needs to be closer to the heating portion 12 to heat the uncooked surface rapidly, and as the barbecue time gradually increases, in order to prevent the uncooked surface from being burnt and aged due to high temperature, the height of the fixing portion 237 is adjusted to make the barbecue food gradually away from the heating portion 12, so as to prevent the temperature from being too high until the barbecue food is turned over again under the condition of ensuring normal barbecue of the barbecue food. Specifically, the process of increasing the height of the fixing portion 237 is a process of roasting the roasted food material, and the process of decreasing the height of the fixing portion 237 is a process of turning over the roasted food material.

Similarly, for barbecue mechanism 2, another kind of using-way is to the great barbecue food material of partial surface area, need right the barbecue food material adopts the mode of the barbecue of rolling, promptly the barbecue food material is in slow rotation state all the time, but because the barbecue eats the material surface area the reason, if fixed part 237 is highly lower, barbecue eat the material easily with arc graticule mesh 13 touches, through the rotating part with the cooperation setting of fixed part 237 when the barbecue food material rotates to the vertical setting of surface area, fixed part 237 is highly highest, avoids the barbecue food material with the touching of arc graticule mesh 13, works as when the barbecue is eaten the material surface area slope level and is placed, fixed part 237 is highly minimum, heating portion 12 can realize right the effective barbecue of material surface area is eaten to the barbecue.

The grill starting position and the grill completing position correspond to both ends of the heating part 12, that is, the grill starting position is an end position that is not moved to the upper portion of the heating part 12, the grill completing position is an end position that is just separated from the upper portion of the heating part 12, and the fork 225 is moved from the grill starting position to the grill completing position to complete the heating and grilling of the grill food material by the heating part 12.

By the use method of the intelligent barbecue oven, automation of a barbecue process is improved, a user only needs to fix the fork 225 inserted with barbecue food materials on the fixed group 22 and take down the fork 225 after barbecue is finished, manual operation in the barbecue process is reduced, and meanwhile barbecue efficiency is improved; the air suction port 35, the fork 225 and the heating part 12 are correspondingly arranged, so that the direct contact between the barbecue food and the arc grid 13 is avoided, the generation of barbecue oil smoke is reduced, and meanwhile, the quick cleaning of the oil smoke during barbecue can be ensured, thereby reducing the influence on the environment.

The foregoing is merely a preferred embodiment of the invention, which is intended to be illustrative and not limiting. It will be understood by those skilled in the art that various changes, modifications and equivalents may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
