Wherein, in order to make the adjusting plate 4 fall, the size of the heating space in the inner cavity of the casing 1 and the uniform heating of the food in the inner cavity of the casing 1 can be automatically determined according to the volume of the food, therefore, the pressure reducing pipe 9 is fixedly installed in the middle of the surface of the heating plate 5, the top end of the pressure reducing pipe 9 penetrates through the middle of the top end of the casing 1, meanwhile, the top of the side wall of the pressure reducing pipe 9 is movably installed with the surface of the casing 1 through a sleeve, the fan blades 10 are fixedly installed on the top of the side wall of the pressure reducing pipe 9 and above the casing 1, meanwhile, the middle of the top end of the casing 1 is fixedly installed with the anti-scald cover 11 for protecting the fan blades 10, meanwhile, the bottom of the inner cavity of the pressure reducing pipe 9 is movably installed with the detecting probe 12, and the bottom end of the detecting probe 12 is located in the inner cavity of the casing, food contact with baking tray 3 that can take the lead, cause detecting probe 12 can produce the clearance with the bottom of decompression pipe 9, cause the air current of casing 1 inner chamber to outwards spill over from decompression pipe 9, make the air current pass through decompression pipe 9 conveying back, act on to flabellum 10, force flabellum 10 to rotate through driving decompression pipe 9, make hot plate 5 take place synchronous rotation, cause hot plate 5 at the pivoted in-process, not only can the even heating, and simultaneously, rotation through hot plate 5, make the air current of casing 1 inner chamber continuous flow, and then change in that the air current scatters everywhere to baking tray 3 upper surface food.

Wherein, in order to make the heating wire 7 in rotatory in-process, can also carry out the electricity connection simultaneously, therefore through the both ends at installation piece 50 respectively fixed mounting have conducting block 51, and conducting block 51 is connected with heating wire 7 through the wire respectively, simultaneously, inner wall at regulating plate 4 respectively fixed mounting have with the electrically conductive ring 8 that touches of conducting block 51 looks adaptation, and the wire makes electrically conductive ring 8 be connected with control switch 2, and make heating wire 7 touch ring 8 by electrically conductive, conducting block 51, heating wire 7, conducting block 51 and electrically conductive ring 8 connect gradually and form the electric circuit, and simultaneously, it is the annular to touch ring 8 through its electrically conductive, therefore conducting block 51 is at the in-process along with heating plate 5 pivoted, contact with its electrically conductive ring 8 is the contact all the time, thereby guarantee that its heating wire 7 can receive sustainable electricity continuously.

Wherein, in order to realize the self-falling of the adjusting plate 4 when overheated, and simultaneously, when the adjusting plate is cooled, the adjusting plate is automatically retracted, so the reset tension spring 6 is set as a shape memory tension spring, meanwhile, the connecting hole arranged on the surface of the mounting block 50 is semicircular, and the end area value of the inner wall of the adjusting plate 4 is eight times of the surface area value of the connecting hole arranged on the mounting block 50, therefore, in the heating process, the inner cavity of the adjusting plate 4 is rapidly heated through the connecting hole because the inner cavity of the shell 1 is heated, when the air flow in the inner cavity of the adjusting plate 4 is heated, the adjusting plate 4 has the trend of pushing downwards due to the air flow expansion, and meanwhile, the extending length of the reset tension spring 6 is increased when the reset tension spring 6 is heated, so the adjusting plate 4 falls down in the processes of self-gravity of the adjusting plate 4, the air flow expansion in the inner, thereby realizing the phenomenon that the working cavity of the inner cavity of the shell 1 can be changed.

Wherein, in order to make the heating wire 7 rotate, so the end face shape of the detection probe 12 is conical, at the same time, the heating plate 5 is fixed on the decompression tube 9 in an inclined manner, when the detection probe 12 contacts with food, the airflow in the inner cavity of the casing 1 overflows from the decompression tube 9, and then the decompression tube 9 is pushed to rotate by the fan blades 10, so that the heating wire 7 starts to rotate, at the same time, the heating plate 5 continuously changes the airflow in the inner cavity of the casing 1 through rotation, at the same time, the conical arrangement of the detection probe 12 avoids the continuous falling of the adjusting plate 4 to make the heating plate 5 contact with the food, so that the gap between the detection probe 12 and the decompression tube 9 is continuously increased in the continuous falling process of the adjusting plate 4, and further the airflow overflowing outwards from the casing 1 is continuously increased, meanwhile, the rotation rate of the heating plate 5 is increased, and at the same time, since the heating plate 5 is obliquely arranged, the heating plate 5 has an upward moving force in the rotating process, so that the adjusting plate 4 is prevented from continuously falling, and the rotation rate of the heating plate 5 is controlled by the detection probe 12.

In order to make the pressure reducing pipe 9 adaptable to the autonomous falling of the adjusting plate 4, the pressure reducing pipe 9 is a telescopic rod capable of transmitting torque, so that the pressure reducing pipe 9 is not only adaptable to the up-and-down movement of the adjusting plate 4, but also capable of transmitting torque through the pressure reducing pipe 9, and thus the heating plate 5 can rotate through the pressure reducing pipe 9 in the process of rotating the fan blades 10.

heated state (shown in fig. 6): the current of the conductive contact ring 8 is transmitted to the heating wire 7 through the conductive block 51 by the control of the control switch 2 and is connected in series through the heating wire 7, one end of the heating wire 7 is transmitted to the other conductive contact ring 8 through the other conductive block 51, so that the circuit access state is realized, secondly, the heating plate 5 begins to radiate heat outwards due to the heating of the heating wire 7, and the airflow in the inner cavity of the shell 1 and the inner cavity of the adjusting plate 4 is firstly heated due to the characteristic that the hot airflow moves upwards, and the reset tension spring 6 is extended under the action of the hot airflow, so that the adjusting plate 4 begins to fall under the synchronous action of gravity and the airflow expansion of the inner cavity of the adjusting plate 4;

baked state (shown in fig. 7): when the adjusting plate 4 continuously falls, the detecting probe 12 will firstly contact with the food, and further the detecting probe 12 is pushed upwards under stress, and the air flow with a certain pressure in the inner cavity of the housing 1 flows out through the pressure reducing pipe 9, and the air flow pressure in the inner cavity of the housing 1 is prevented from continuously increasing by the air flow overflowing from the pressure reducing pipe 9, meanwhile, the overflowing air flow acts on the fan blade 10 and finally overflows from the anti-scalding cover 11 to the outside air, meanwhile, the fan blade 10 pushes the pressure reducing pipe 9 to rotate by the air flow pushing in the inner cavity of the pressure reducing pipe 9, and further the pressure reducing pipe 9 rotates on the adjusting plate 4 by driving the mounting block 50, and simultaneously, the pressure reducing pipe 9 drives the heating plate 5 to synchronously rotate, and then, in the rotating process of the heating plate 5, the heating plate 5 can also synchronously rotate the heating wire 7, and the heating part of the heating wire 7 in the inner cavity of the housing 1 is continuously changed by the heating plate 5, the airflow at each position of the inner cavity of the shell 1 is uniformly heated, and meanwhile, in the process of heat dissipation of the heating plate 5, the airflow in the inner cavity of the shell 1 continuously flows through the rotation of the heating plate 5, so that food is uniformly heated at each position in the baking process;

and (4) finishing baking: the box cover on the shell 1 is opened, so that a large amount of hot air in the inner cavity of the shell 1 overflows outwards, the temperature of the air in the inner cavity of the adjusting plate 4 is reduced, the thermal expansion of the air is reduced, and meanwhile, the adjusting plate 4 is pulled back by the reset tension spring 6 in a temperature cooling state, so that the purpose of baking food is fulfilled.
