Description

Technical Field

[0001] The invention belongs to the technical field of cake making machines and control systems, and particularly relates to a control system for a full-automatic cake making machine. Background Art

[0002] The process of making a pancake includes cutting, kneading, pressing, and baking, all of which are done manually. This results in a heavy workload, slow efficiency, and high labor costs. While current pancake making machines can address these issues by completing these steps and improving efficiency, their control systems often result in poor quality pancakes. Summary of the Invention

[0003] The invention provides a control system for a fully automatic cake making machine, aiming to solve the problem that cake making effect of the cake making machine in the prior art is poor.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The present invention provides a control system for a fully automatic cake making machine, comprising a power supply, a control unit, a display unit, a heating unit, a tray unit, a powder tray unit, a cake pushing unit, a cake pressing unit, a stirring unit, and a water pump and oil pump unit;

[0006] The control unit and the display unit are both electrically connected to the power supply, and the display unit is electrically connected to the control unit, and a cake-making parameter input area is provided on the display unit; the heating unit, tray unit, powder tray unit, cake-pushing unit, cake-pressing unit, stirring unit and water pump and oil pump unit are all electrically connected to the control unit, and the cake-making steps are completed under the action of the control unit.

[0007] A further solution: the heating unit includes a baking tray heating module and a temperature sensor module; the control unit drives the baking tray heating module to heat, the temperature sensor module collects the temperature of the baking tray heating module and transmits it to the control unit, and the control unit controls the temperature of the baking tray heating module to maintain a constant temperature according to the temperature collected by the temperature sensor module.

[0008] Based on the above solution, the control unit controls the temperature of the baking tray heating module to maintain a constant temperature, that is, the temperature of the baking tray heating module is always maintained at a temperature that can bake the cakes mature, without the need for manual temperature adjustment, which is more convenient.

[0009] A further solution: the pallet unit includes a position point IR1, a position point IR2, a position point IR11, a position point IR3 and a position point IR4;

[0010] The specific steps of the control unit driving the tray unit to move are:

[0011] A1. The control unit drives the tray unit to move from the position point IR3 to the position point IR2, and the tray unit stops and enters a tray waiting state;

[0012] A2. After the tray waiting state ends, the control unit drives the tray unit to move from the position point IR2 to the position point IR1, and the tray unit stops for t1 seconds;

[0013] A3, the tray unit moves from the position point IR1 to the position point IR2, and the tray unit stops for t2 seconds;

[0014] A4, the tray unit moves from the position point IR2 to the position point IR1, and the tray unit stops for t3 seconds;

[0015] A5. The tray unit moves from the position IR1 to the position IR2, and the tray unit stops for t4 seconds;

[0016] A6. The tray unit moves from the position IR2 to the position IR11, and the tray unit stops for t5 seconds;

[0017] A7: The tray unit moves from the position IR11 to the position IR4, stops for t6 seconds, and transfers the dough to the dough pushing unit;

[0018] A8. The tray unit moves from the position point IR4 to the position point IR3 to reset and stop moving.

[0019] Based on the above solution, during the tray waiting state, the tray unit receives the flour transferred by the flour tray unit. In steps A2 to A5, the tray unit moves back and forth between position IR1 and position IR2 multiple times, causing the tray unit to move up and down multiple times, and combined with the stirring action of the stirring control unit, it can play a role in kneading the dough. In steps A6 and A7, the tray unit moves to the position of the cake pushing unit, and the control unit drives the tray to tilt, causing the dough in the tray unit to fall into the cake pushing unit.

[0020] Further solution: in step A1, the tray unit enters the tray waiting state, and the control unit drives the stirring unit to operate until, in step A6, the tray unit moves from the position point IR2 to the position point IR11 for t7 seconds, and the control unit controls the stirring unit to stop.

[0021] Based on the above solution, the stirring unit rotates and stirs in the tray unit, which can simulate manual kneading of dough, so that the flour in the tray unit forms dough.

[0022] Further solution: the control unit also includes a function for repairing abnormalities of the stirring unit; when the stirring unit is abnormally overloaded, the control unit drives the tray unit to move downward and then drives the stirring unit to rotate; after the stirring unit resumes its rotation speed, the control unit drives the tray unit to move upward and reset.

[0023] Based on the above solution, the control unit can automatically repair the abnormal problem when the stirring unit is abnormally overloaded, without the need for manual repair, thereby further optimizing the automation function of the fully automatic cake-making machine.

[0024] Further solution: When the stirring unit starts to rotate at t8 seconds, the control unit drives the water pump and oil pump unit to add oil to the tray unit. After t9 seconds, the control unit stops and adds water to the tray unit. 10 Seconds stop.

[0025] Based on the above solution, the water pump and oil pump unit adds water and oil to the tray unit to promote the flour in the tray unit to form a mass. In addition, the amount of water and oil added is controlled by the control unit, and the measurement is more accurate, thereby achieving better cake making effect.

[0026] A further solution: the powder tray unit includes micro-switch signal points F1, F3, and F2 arranged in sequence in a forward direction, and micro-switch 1 and micro-switch 2 are provided around the powder tray unit; initially, the micro-switch signal point F1 is located at the micro-switch 1, and the micro-switch signal point F2 is located between the micro-switch 1 and the micro-switch 2;

[0027] The specific steps of the control unit driving the powder tray unit to move are:

[0028] B1. When the tray unit enters the tray waiting state in step A1, the control unit drives the powder tray unit to rotate, and the micro signal point F2 rotates forward to the micro switch 2, and the powder tray unit stops. 11 After 10 seconds, the tray waiting state in step A1 ends;

[0029] B2. The powder tray unit rotates, and the micro signal point F3 rotates forward to the micro switch 2 and stops rotating;

[0030] B3, in step A5, the tray unit stops for t4 seconds 12At 1 second, the control unit drives the powder tray unit to rotate, and the micro motion signal point F1 rotates forward to the micro switch 1 and resets to stop.

[0031] Based on the above scheme, in the step B1, the powder tray unit conveys flour into the tray unit; in the step B2, the powder tray unit stops conveying flour; in the step B3, while the micro signal point F1 rotates forward to the micro switch 1, the powder tray unit sprinkles flour into the tray unit, which can prevent the dough kneaded on the tray from sticking to the tray. When the micro signal point F1 rotates to the micro switch 1, the powder tray unit stops sprinkling flour.

[0032] A further solution: the cake pushing unit includes position point IR5, position point IR6 and position point IR7;

[0033] The specific steps of the control unit driving the cake pushing unit to move are:

[0034] C1. When the tray unit moves from the position IR2 to the position IR11 at the t7th second in step A6, the control unit drives the cake pushing unit to move from the position IR5 to the position IR6, and the cake pushing unit stops to receive the dough transferred by the tray unit in step A7;

[0035] C2, after receiving the dough, the dough pushing unit moves forward at position IR6. 13 After a few seconds, it returns to the position IR5, stops moving, and enters the first push-cake waiting state;

[0036] C3. After the first cake-pushing waiting state ends, the control unit drives the cake-pushing unit to move at the position IR5. 14 Second stop 15 After a few seconds, it returns to the position IR5 and stops, and the cake pushing unit stops moving and enters the second cake pushing waiting state;

[0037] C4. After the second cake-pushing waiting state ends, the control unit drives the cake-pushing unit to move from the position point IR5 to the position point IR7 and then returns to the position point IR5 to stop and perform a reset stop.

[0038] Based on the above solution, in step C1, the position IR6 is the position where the cake pushing unit receives the dough, and the cake pushing unit moves from the position IR5 to the position IR6 to ensure that the cake pushing unit accurately receives the dough. In step C2, the cake pushing unit moves forward at the position IR6. 13The dough is positioned in the pressing unit and pushed to the correct position so that the dough is directly below the pressing unit. In step C3, the pressing unit positions the dough during the pressing process to prevent the dough from moving. In step C4, the pressing unit pushes the pressed dough out of the fully automatic dough making machine.

[0039] A further solution: the cake pressing unit includes position point IR8, position point IR9, position point IR10, position point IR12 and position point IR13;

[0040] The specific steps of the control unit driving the cake pressing unit to move are:

[0041] D1, when the cake pushing unit in step C2 returns to the position point IR5, the control unit drives the cake pressing unit to move from the position point IR10 to the position point IR8, and the cake pressing unit stops t 16 Second;

[0042] D2, the cake pressing unit moves from the position point IR8 to the position point IR13, and the cake pressing unit stops t 17 seconds, and at the stop t 17 During the period of 10 seconds, the first cake-pushing waiting state in step C2 ends, and the cake-pushing unit executes step C3;

[0043] D3, the cake pressing unit moves from the position point IR13 to the position point IR12, and the cake pressing unit stops t 18 Second;

[0044] D4, the cake pressing unit moves from the position point IR12 to the position point IR9, and the cake pressing unit stops t 19 Second;

[0045] D5, the cake pressing unit moves from the position point IR9 to the position point IR13; the cake pressing unit moves from the position point IR13 to the position point IR12, and the cake pressing unit stops t 20 After seconds, it returns to the position IR13;

[0046] D6, the cake pressing unit moves from the position point IR13 to the position point IR12 and then continues to move forward t 21 The machine returns to the position point IR10 and stops, and resets, and the second cake-pushing waiting state in step C3 ends.

[0047] Based on the above solution, in step D1, the cake pressing unit is lowered and pressed on the dough for the first time, and the cake pressing unit stops t 16In step D2, the cake pressing unit rises, and the cake pushing unit positions the cake. In steps D3 to D6, the cake pressing unit moves between position IR13 and position IR12 multiple times, so that the cake pressing unit presses and bakes the dough multiple times. In step D6, the cake baking is completed, and the cake pressing unit returns to its initial position.

[0048] A further solution: the cake pressing unit is divided into a first gear, a second gear and a third gear according to the parameters of the fully automatic cake making machine set by the display unit;

[0049] When the cake pressing unit is in the first gear, the cake pressing unit in step D5 stops at the position point IR12 for 2 seconds and then returns to the position point IR13;

[0050] When the cake pressing unit is in the second gear, the cake pressing unit in step D5 stops at the position point IR12 for 6 seconds and then returns to the position point IR13, and repeats the movement of the cake pressing unit from the position point IR13 to the position point IR12 and the movement of the cake pressing unit from the position point IR13 to the position point IR12 and the movement of the cake pressing unit from the position point IR13 to the position point IR13 after stopping for 6 seconds;

[0051] When the cake pressing unit is in the third gear, the cake pressing unit in step D5 stops at the position point IR12 for 14 seconds and then returns to the position point IR13, and repeats the movement of the cake pressing unit from the position point IR13 to the position point IR12, and the cake pressing unit stops for 14 seconds and then returns to the position point IR13.

[0052] Based on the above scheme, the second and third gears both move the pancake pressing unit from position IR13 to position IR12 one more time than the first gear. Furthermore, the third gear stays at position IR12 for 8 seconds longer than the second gear, resulting in the pancakes baked in the first, second, and third gears having increasing crispness. Furthermore, the three gears can meet different demands for pancake texture as well as ingredients, making it easier for users to choose and improving their experience.

[0053] Further solution: A control system for a fully automatic cake-making machine, further comprising a safety gate unit arranged on the outside of the cake-pressing unit, wherein the safety gate unit is provided with a transmitter for emitting a grating and a receiver for receiving the grating; when a person or object passes through the safety gate unit and blocks the receiver from receiving the grating emitted by the transmitter, the control unit controls the cake-pressing unit to stop moving.

[0054] Based on the above solution, the safety door unit can, on the one hand, prevent the cake pressing unit from pressing the user's hand when pressing the cake; on the other hand, it can prevent the cake pressing unit from pressing other objects when pressing the cake and damaging the baking tray; thereby improving the safety performance of the fully automatic cake making machine.

[0055] A further solution: the control unit also includes a function for repairing abnormalities of the cake pressing unit; when the cake pressing unit has an abnormal overcurrent, the control unit first drives the cake pressing unit to reverse and move upward, and then drives the cake pressing unit to move downward.

[0056] Based on the above solution, the control unit can automatically repair the abnormal problem when the cake pressing unit has abnormal overcurrent, without the need for manual repair, thereby further optimizing the automation function of the fully automatic cake making machine.

[0057] A further solution: a current sampler is provided on the control unit. When the fully automatic cake-making machine is started, the control unit drives the heating unit, tray unit, powder tray unit, cake pushing unit, cake pressing unit, stirring unit and water pump and oil pump unit to run for 1 second. The current sampler collects current signals from the heating unit, tray unit, powder tray unit, cake pushing unit, cake pressing unit, stirring unit and water pump and oil pump unit respectively. The control unit judges whether the heating unit, tray unit, powder tray unit, cake pushing unit, cake pressing unit, stirring unit and water pump and oil pump unit are faulty according to the current signals collected by the current sampler.

[0058] Further solution: A control system of a fully automatic cake-making machine also includes a cleaning unit, which is electrically connected to the control unit; when the fully automatic cake-making machine finishes operation, the control unit drives the cleaning unit to clean the water pump and oil pump unit.

[0059] Based on the above solution, after the cake making is completed, the cleaning unit cleans the water tank and the oil tank in the water pump and oil pump unit, which not only ensures food hygiene and dietary health, but also avoids manual hand washing and saves labor costs.

[0060] A further solution: during the period when the control unit drives the cake pushing unit to complete the cake pushing action and drives the cake pressing unit to complete the cake pressing action, the control unit drives the tray unit, the powder tray unit and the stirring unit to jointly complete a dough kneading action.

[0061] Based on the above scheme, in the fully automatic cake-making machine, the cake-pushing action and the cake-pressing action in the current cake-making process are performed simultaneously with the dough-forming action in the next cake-making process, which can improve the cake-making efficiency of the fully automatic cake-making machine.

[0062] The beneficial effects of the present invention are:

[0063] In the present invention, the control unit drives the water pump and oil pump unit and the flour tray unit to put precise amounts of water, oil and flour into the tray unit; the control unit drives the stirring unit to stir in the tray unit so that the flour in the tray unit can form a ball, and the control unit drives the tray unit to transfer the dough to the cake pushing unit; the cake pushing unit positions the dough so that the dough is directly below the cake pressing unit; the control unit drives the cake pressing unit to press the dough into a cake shape, and the control unit uses the heating unit to keep the baking tray in the cake pressing unit at a temperature suitable for baking cakes, so that the cake pressing unit bakes the cake until mature, avoiding the problem of undercooked or over-burned cakes; after baking, the control unit drives the cake pushing unit to push out the baked cake. The cakes made by the present invention are of better quality, have a higher success rate, and taste better. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0075] The time (t1~t 21 ) are specifically selected (including but not limited to the time values ​​in the following embodiments) to further illustrate the present invention:

[0076] like Figure 1 As shown, this embodiment provides a control system for a fully automatic cake making machine, including a power supply, a control unit, a display unit, a heating unit, a tray unit, a powder tray unit, a cake pushing unit, a cake pressing unit, a stirring unit, and a water pump and oil pump unit;

[0077] The control unit and the display unit are both electrically connected to the power supply, and the display unit is electrically connected to the control unit, and a cake-making parameter input area is provided on the display unit; the heating unit, tray unit, powder tray unit, cake-pushing unit, cake-pressing unit, stirring unit and water pump and oil pump unit are all electrically connected to the control unit, and the cake-making steps are completed under the action of the control unit.

[0078] Specifically, during the period when the control unit drives the cake pushing unit to complete the cake pushing action and drives the cake pressing unit to complete the cake pressing action, the control unit drives the tray unit, the powder tray unit and the stirring unit to jointly complete a dough-forming action.

[0079] The fully automatic cake-making machine is also equipped with a power button, a start button, and a buzzer for alarming or reminding that cake making is complete. When the power is on, pressing the power button puts the fully automatic cake-making machine into standby mode. The user can set parameters such as the number of cakes to be made, the hardness of the cakes, and the gear position of the cake pressing unit in the cake making parameter input area on the display unit. Pressing the start button starts the fully automatic cake-making machine.

[0080] A more specific example of the heating unit is: the heating unit includes a baking tray heating module and a temperature sensor module; the control unit drives the baking tray heating module to heat, the temperature sensor module collects the temperature of the baking tray heating module and transmits it to the control unit, and the control unit controls the temperature of the baking tray heating module to maintain a constant temperature according to the temperature collected by the temperature sensor module.

[0081] The pancake pressing unit includes an upper baking tray and a lower baking tray, and the baking tray heating module is used to heat the upper and lower baking trays. The upper baking tray is set to a temperature of 255-265 degrees Celsius, and the lower baking tray is set to a temperature of 265-275 degrees Celsius. When the temperature on the upper or lower baking tray reaches 300-310 degrees Celsius, the buzzer will sound an alarm.

[0082] like Figure 2 and Figure 3 As shown, a more specific example of the tray unit is as follows: the tray unit includes position points IR1, IR2, IR11, IR3 and IR4. The tray unit is driven by a synchronous motor and includes a tray.

[0083] The specific steps of the control unit driving the tray unit to move are:

[0084] A1. The control unit drives the tray unit to move from the position point IR3 to the position point IR2, and the tray unit stops and enters a tray waiting state;

[0085] A2. After the tray waiting state ends, the control unit drives the tray unit to move from the position point IR2 to the position point IR1, and the tray unit stops for 5 seconds;

[0086] A3, the tray unit moves from the position point IR1 to the position point IR2, and the tray unit stops for 3 seconds;

[0087] A4. The tray unit moves from the position IR2 to the position IR1, and the tray unit stops for 30 seconds;

[0088] A5. The tray unit moves from the position IR1 to the position IR2, and the tray unit stops for 4 seconds;

[0089] A6. The tray unit moves from the position IR2 to the position IR11, and the tray unit stops for 4 seconds;

[0090] A7, the tray unit moves from the position point IR11 to the position point IR4, the tray unit stops for 3 seconds, and the tray unit transfers the dough to the cake pushing unit;

[0091] A8. The tray unit moves from the position point IR4 to the position point IR3 to reset and stop moving.

[0092] A more specific example of the above scheme is: Steps A1 to A8 are the actions performed by the tray unit when making a pancake. When making pancakes continuously (making 2 or more pancakes), the tray unit in step A8 moves from the position point IR4 to the position point IR3 for reset and then continues to execute steps A1 to A8.

[0093] In a more specific example, the stirring unit is driven by a 310V, 100W stirring DC motor. The power supply boosts the 220V mains voltage to 310V to power the stirring DC motor. The stirring unit includes a stirrer, and the control unit drives the stirrer to stir the flour into a dough.

[0094] Specifically, in step A1, the tray unit enters the tray waiting state, and the control unit drives the stirring unit to operate until, in step A6, the tray unit moves from the position point IR2 to the position point IR11 for 0.4 seconds, and the control unit controls the stirring unit to stop.

[0095] Based on the above scheme, the control unit also includes a function for repairing abnormalities of the stirring unit; when the stirring unit is abnormally overloaded, the control unit drives the tray unit to move downward 5mm and then drives the stirring unit to rotate; after the stirring unit resumes its rotation speed, the control unit drives the tray unit to move upward and reset.

[0096] A more specific example of the water pump and oil pump unit is: 21 seconds after the stirring unit starts to rotate, the control unit drives the water pump and oil pump unit to add oil to the tray unit, stops for 2.2 seconds, and then adds water to the tray unit for 10 seconds.

[0097] Among them, the water pump and oil pump both use DC12V flow peristaltic pumps, and the control unit drives the water pump and oil pump to work. For the water pump, 4 square wave pulse signals are output for each rotation, and the signal is fed back to the control unit. The control unit counts internally, and counting 940 square wave pulse signals is the default mid-range water volume of 10.7mL. 15 levels of water volume can be set to adjust the soft and hard taste of the cake, and each level is separated by 0.1mL of water. For the oil pump, the internal timer of the control unit is synchronized, and when the timing reaches 2.2 seconds (1.2mL of oil is added), the oil pump is immediately turned off.

[0098] In addition, the water pump and oil pump unit is also provided with a water return function and an oil return function. When the user presses the power button, the fully automatic cake making machine is in a standby state, at which time the oil pump returns oil for 20 seconds and the water pump returns water for 10 seconds.

[0099] The water pump and oil pump unit is also equipped with a water shortage alarm function. A float magnetic ring is installed inside the water tank, and a magnetic sensor is installed at the safety water level line outside the water tank. When the water level drops to the safety water level line, the magnetic sensor is triggered to generate a voltage signal, which is fed back to the control unit. The control unit drives the buzzer to sound an alarm three times in a row, and the control unit triggers the start button. After the cake pressing unit and the stirring unit complete their current work, the fully automatic cake maker enters the standby state (the cake pressing control requires the dough to be made into mature cakes before the fully automatic cake maker enters the standby state). After the user adds water to the water tank, the user needs to manually press the start button for the fully automatic cake maker to continue working.

[0100] like Figure 4 and Figure 5 As shown, a more specific example of the powder tray unit is as follows: the powder tray unit includes micro-switch signal points F1, F3, and F2 arranged in a forward direction (the forward direction can be clockwise or counterclockwise), and micro-switch 1 and micro-switch 2 are arranged around the powder tray unit. Initially, micro-switch signal point F1 is located at micro-switch 1, and micro-switch signal point F2 is located between micro-switch 1 and micro-switch 2. The powder tray unit is driven by a synchronous motor.

[0101] The specific steps of the control unit driving the powder tray unit to move are:

[0102] B1. When the tray unit enters the tray waiting state in step A1, the control unit drives the powder tray unit to rotate, and the micro motion signal point F2 rotates forward to the micro switch 2. The powder tray unit stops for 5 seconds, and the tray waiting state in step A1 ends.

[0103] B2. The powder tray unit rotates, and the micro signal point F3 rotates forward to the micro switch 2 and stops rotating;

[0104] B3. At the second second of the four seconds during which the tray unit stops in step A5, the control unit drives the powder tray unit to rotate, and the micro motion signal point F1 rotates forward to the micro switch 1 and resets to stop.

[0105] A further solution for the above example is as follows: the flour tray unit includes a flour box that rotates in a forward direction and a box shell that is fixedly mounted outside the flour box; the micro-switch signal points F1, F3, and F2 are sequentially positioned in a forward direction on the flour box, and the micro-switch 1 and micro-switch 2 are positioned on the box shell. Initially, the micro-switch signal point F1 is located at the micro-switch 1.

[0106] It should be noted that: the micro signal point F1 and the micro switch 1 are on the same cross section, the micro signal point F3, the micro signal point F2 and the micro switch 2 are on the same cross section, when the flour box is rotating, the micro signal point F1 will not rotate to the position of the micro switch 2, and the micro signal point F1 will not trigger the micro switch 2. Similarly, the micro signal point F2 and the micro signal point F3 will not rotate to the position of the micro switch 1, and the micro signal point F2 and the micro signal point F3 will not trigger the micro switch 1.

[0107] like Figure 6 and Figure 7 As shown in FIG. 1 , a more specific example of the cake pushing unit is as follows: the cake pushing unit includes position points IR5, IR6, and IR7. The cake pushing unit is driven by a synchronous motor and includes a cake pusher. The control unit drives the cake pusher to receive and position the dough delivered by the tray unit.

[0108] The specific steps of the control unit driving the cake pushing unit to move are:

[0109] C1. When the tray unit moves from the position IR2 to the position IR11 for 0.4 seconds in step A6, the control unit drives the cake pushing unit to move from the position IR5 to the position IR6, and the cake pushing unit stops to receive the dough transferred by the tray unit in step A7;

[0110] C2: After receiving the dough, the cake pushing unit moves forward at position IR6 for 1 second and then returns to position IR5, stops moving, and enters the first cake pushing waiting state;

[0111] C3, after the first cake-pushing waiting state ends, the control unit drives the cake-pushing unit to move at the position point IR5 for 0.5 seconds and stop for 10 seconds, then return to the position point IR5 and stop, and the cake-pushing unit stops moving and enters the second cake-pushing waiting state;

[0112] C4. After the second cake-pushing waiting state ends, the control unit drives the cake-pushing unit to move from the position point IR5 to the position point IR7 and then returns to the position point IR5 to stop and perform a reset stop.

[0113] like Figure 8 and Figure 9 As shown, a more specific example of the cake-pressing device is as follows: the cake-pressing unit includes positions IR8, IR9, IR10, IR12, and IR13. The cake-pressing unit is driven by a 310V, 100W DC cake-pressing motor. The power supply boosts the 220V mains voltage to 310V to power the DC cake-pressing motor. The cake-pressing unit includes the upper baking tray and the lower baking tray. The control unit drives the upper baking tray to press and bake the dough on the lower baking tray.

[0114] The specific steps of the control unit driving the cake pressing unit to move are:
