The driving member 42 includes a screw 422 and a motor 423, one end of the screw 422 is rotatably matched with the limiting block 41, the other end of the screw 422 passes through a through hole on the wall of the guide groove 11 and is connected with the motor 423, the motor 423 drives the screw 422 to rotate, so as to drive the limiting block 41 to move back and forth, the screw 422 is driven to rotate by the motor 423, the moving distance of the limiting block 41 is adjusted, and the rotating angle of the second matching portion 313 is adjusted.
The force accumulating elastic member 31 may store elastic potential energy when the upper cover assembly 20 pivots from the unfolded position to the closed position, and the stopper 41 drives the second fitting portion 313 to rotate at a certain angle with respect to the first fitting portion 312 when the upper cover assembly 20 is in the closed position, whereby the elastic potential energy stored in the force accumulating elastic member 31 acts on the connection portion 22 in a torsional force manner to apply an upward force to the upper cover assembly 20, thereby reducing the pressure of the upper cover assembly 20 on the food, and achieving a weight reduction effect.
When cooking food, set up the culinary art mode, under different culinary art modes, different food has different preset pressure value F, for example the preset pressure value F of water fried dumpling is 400g, the preset pressure value F of leavened dough cake is 700g, according to the culinary art mode of setting for, controlling means automatically regulated motor 423 work, motor 423 drives lead screw 422 rotation, change stopper 41 migration distance, thereby it rotates for first cooperation portion 312 to drive second cooperation portion 313, change the contained angle between the two, and then change the elastic potential energy of power elastic component 31, change the moment of torsion of power elastic component 31 to upper cover subassembly 20.
Place food on base component, upper cover subassembly 20 lock is on base component 10, controlling means works according to the working parameter who disposes (for example preset pressure, heating time, temperature etc.), because the influence of the difference of food thickness or error, detect the pressure value that upper cover subassembly 20 was used in on base component 10, the pressure value that upper cover subassembly 20 self gravity value backstep food culinary art received, through the pressure value that the food culinary art that obtains received with preset pressure value comparison, again feedback adjustment, make food cook under preset pressure value all the time, end up to food culinary art.
Specifically, the pressure detection device 50 detects a second pressure value F2 applied by the upper cover assembly on the base assembly, and calculates a first pressure value F1 applied to food in the cooking cavity through a gravity value G of the upper cover assembly and the second pressure value F2, where F1 is G-F2, compares whether the first pressure value F1 is the same as a preset pressure value F, and when F1 is F, the control device controls the frying and baking machine to normally operate; when F1 ≠ F, the control device controls the motor 423 to operate, for example, when F1 > F, the control limit block 41 moves forward, the elastic potential energy of the power elastic piece 31 is increased, the torsion force of the power elastic piece 31 on the upper cover assembly 20 is increased, and the pressure of the upper cover assembly 20 on the food is reduced until F1 ≠ F; when F1 < F, the control stopper 41 moves backward, reducing the elastic potential energy of the power elastic member 31, and reducing the torsion force of the power elastic member 31 on the cover assembly 20, thereby increasing the pressure of the cover assembly 20 on the food until F1 is F.
According to the frying and baking machine provided by the embodiment of the invention, through the arrangement, food is subjected to a proper pressure value, the food is prevented from being crushed, and the cooking effect and the cooking mouthfeel of the food are improved.
