[0046] The embodiment of the present invention provides a cooking device cover flip control method, see Figures 2 to 4 The cooking device in the embodiment of the present invention comprises a base 1, a flap 2 and an elastic component 3, wherein the flap 2 is rotatably connected to the base 1, and the elastic component 3 is connected to the flap 2 to provide elastic force to the flap 2 so that the flap 2 is kept in an open position. Figure 1 The cooking device cover flip control method of the embodiment of the present invention includes:

[0047] S10, setting a pressure sensor 6, the pressure sensor 6 is used to detect the pressure applied to the pressure sensor 6 when the flip cover 2 is in the open position;

[0048] S20, setting an elastic force adjustment mechanism 4, the elastic force adjustment mechanism 4 is connected to the elastic component 3, and is used to adjust the elastic force applied by the elastic component 3 on the flip cover 2;

[0049] S30, obtaining the pressure detected by the pressure sensor 6;

[0050] S40, issuing an adjustment instruction according to the pressure detected by the pressure sensor 6, so that the elastic force adjustment mechanism 4 adjusts the pressure applied by the elastic component 3 to the flip cover 2 according to the adjustment instruction, until the pressure detected by the pressure sensor 6 reaches the target pressure.

[0051] The embodiment of the present invention obtains the elastic force applied by the elastic component 3 on the flip cover 2, and issues an adjustment instruction according to the pressure detected by the pressure sensor 6, so that the elastic force adjustment mechanism 4 adjusts the pressure applied by the elastic component 3 on the flip cover 2 according to the adjustment instruction until the pressure detected by the pressure sensor 6 reaches the target pressure. This can ensure that the flip cover 2 is fully opened, eliminate the problem caused by the attenuation of the elastic component 3, and improve the user experience.

[0052] In some embodiments, an adjustment instruction is issued according to the pressure detected by the pressure sensor 6, so that the elastic force adjustment mechanism 4 adjusts the pressure applied to the flip cover 2 by the elastic component 3 according to the adjustment instruction until the pressure detected by the pressure sensor 6 reaches the target pressure, including: when the pressure detected by the pressure sensor 6 is less than the target pressure, an adjustment instruction to increase the pressure is issued, and the adjustment instruction instructs the elastic force adjustment mechanism 4 to drive the elastic component 3 to move to increase the compression of the elastic component 3.

[0053] When the cooking device of the embodiment of the present invention is powered on and the flap 2 is flipped up, the pressure sensor 6 will continuously monitor the pressure value Fn given to it by the flap 2. By comparing the pressure value fed back with the target pressure N, it can be determined whether the elastic force needs to be adjusted. When Fn < N, it means that the elastic force given to the flap 2 by the elastic component 3 is too small. A command is sent to the elastic force adjustment mechanism 4 to drive the elastic component 3 to move, increase the compression of the elastic component 3, and the force given to the flap 2 by the elastic component 3 becomes larger. The pressure value Fn of the flap 2 acting on the pressure sensor 6 also increases. When the real-time feedback pressure value Fn = N is monitored, a command is sent to stop the elastic force adjustment mechanism 4. Through automatic adjustment, the problem of consistency of factory feel is solved and the fault tolerance rate of production is improved. In addition, the user can adjust the target pressure through the pressure input component to meet personalized needs and improve user experience.

[0054] In some embodiments, an adjustment instruction is issued according to the pressure detected by the pressure sensor 6, so that the elastic force adjustment mechanism 4 adjusts the pressure applied to the flip cover 2 by the elastic component 3 according to the adjustment instruction until the pressure detected by the pressure sensor 6 reaches the target pressure, including: when the pressure detected by the pressure sensor 6 is greater than the target pressure, an adjustment instruction to reduce the pressure is issued, and the adjustment instruction instructs the elastic force adjustment mechanism 4 to drive the elastic component 3 to move to reduce the compression of the elastic component 3.

[0055] When the cooking device of the embodiment of the present invention is powered on and the flap 2 is flipped up, the pressure sensor 6 will continuously monitor the pressure value Fn given to it by the flap 2. By comparing the pressure value fed back with the target pressure N, it can be determined whether the elastic force needs to be adjusted. When Fn>N, it means that the elastic force given to the flap 2 by the elastic component 3 is too large. A command is sent to the elastic force adjustment mechanism 4 to drive the elastic component 3 to move, reduce the compression of the elastic component 3, and the force given to the flap 2 by the elastic component 3 becomes smaller. The pressure value Fn of the flap 2 acting on the pressure sensor 6 also becomes smaller. When the real-time feedback pressure value Fn=N is monitored, a command is sent to stop the elastic force adjustment mechanism 4. Through automatic adjustment, the problem of consistency of factory feel is solved and the fault tolerance rate of production is improved. In addition, the user can adjust the target pressure through the pressure input component to meet personalized needs and improve user experience.

[0056] An embodiment of the present invention provides a cooking device, which may include a cooking machine, an electric baking pan, etc.

[0057] The cooking device of the embodiment of the present invention can implement the control method of the above embodiment, and the above control method can be applied to the cooking device of the embodiment of the present invention. The following embodiment of the cooking device can be used to understand the control method of the embodiment of the present invention, and the embodiment of the above control method can also be used to understand the cooking device of the embodiment of the present invention.

[0058] See also Figures 2 to 4 The cooking device of the embodiment of the present invention comprises a base 1 and a flap 2, and the flap 2 is rotatably connected to the base 1, so that the flap 2 can be opened or closed relative to the base 1. Taking a cooking machine as an example, during cooking, the flap 2 is closed relative to the base 1 to maintain the temperature of the cooking area. When adding ingredients or taking out the cooked food, the flap 2 is rotated to open relative to the base 1.

[0059] The cooking device of the embodiment of the present invention further includes an elastic component 3, which is connected to the flip cover 2 and is used to provide elastic force to the flip cover 2 so that the flip cover 2 is kept in the open position. The elastic component 3 can be arranged between the flip cover 2 and the base 1, and the elastic component 3 acts on the flip cover 2. The elastic force of the elastic component 3 can make the flip cover 2 rotate relative to the base 1 to the open state and keep it in the open position.

[0060] The cooking device of the embodiment of the present invention further comprises an elastic force adjustment mechanism 4, which is connected to the elastic component 3 and is used to adjust the elastic force applied by the elastic component 3 on the flip cover 2. When the elastic force applied by the elastic component 3 on the flip cover 2 is too small, the flip cover 2 cannot be opened automatically or cannot be kept in the open position. Figure 2 As shown in the figure, when the elastic force exerted by the elastic component 3 on the flip cover 2 is sufficient, the flip cover 2 should be located at the dotted line position and connected to the pressure sensor 6. However, when the elastic force exerted by the elastic component 3 on the flip cover 2 is too small, the flip cover 2 cannot be kept at the open position shown by the dotted line, but is located at the position shown by the solid line, and the so-called "head removal" phenomenon occurs. In the embodiment of the present invention, the elastic force adjustment structure can increase the elastic force exerted by the elastic component 3 on the flip cover 2, so that the flip cover 2 can be automatically opened and maintained in the open position. Figure 3 As shown, when the elastic force adjustment mechanism 4 drives the elastic component 3 to move from the position shown by the dotted line to the position shown by the solid line, the elastic force applied by the elastic component 3 on the flip cover 2 increases, so that the flip cover 2 can be kept in the open position. Alternatively, when the elastic force applied by the elastic component 3 on the flip cover 2 is too large and it is difficult for the user to close the flip cover 2, the elastic force adjustment structure can reduce the elastic force applied by the elastic component 3 on the flip cover 2, so that the flip cover 2 can be closed with less effort.

[0061] The cooking device of the embodiment of the present invention further includes a pressure sensor 6, which is arranged on the base 1 and is used to detect the pressure applied to the pressure sensor 6 by the flip cover 2 in the open position. When the flip cover 2 is opened and in the open position, the pressure sensor 6 can detect the pressure of the flip cover 2 acting on the pressure sensor 6 by contacting with the flip cover 2, so as to reflect the elastic force of the elastic component 3 acting on the flip cover 2 when the flip cover 2 is in the open state. The greater the elastic force of the elastic component 3 acting on the flip cover 2, the greater the pressure detected by the pressure sensor 6, and the smaller the pressure of the elastic component 3 acting on the flip cover 2, the smaller the pressure detected by the pressure sensor 6, and even when the elastic force of the elastic component 3 acting on the flip cover 2 cannot keep the flip cover 2 in the open position, the pressure detected by the pressure sensor 6 is 0. By setting the pressure sensor 6, the elastic force of the elastic component 3 acting on the flip cover 2 can be timely understood, and it can be judged whether the elastic force can keep the flip cover 2 in the open position, or whether the elastic force makes the external force of closing the flip cover 2 too large.

[0062] The cooking device of the embodiment of the present invention further includes a control unit 5, which is connected to a pressure sensor 6 and an elastic force adjustment mechanism 4. The control unit 5 issues an adjustment instruction according to the pressure detected by the pressure sensor 6, so that the elastic force adjustment mechanism 4 adjusts the pressure applied by the elastic component 3 to the flap 2 according to the adjustment instruction until the pressure detected by the pressure sensor 6 reaches the target pressure. In the embodiment of the present invention, the target pressure can be set according to the specific situation. For example, the target pressure can be such that the elasticity of the elastic component 3 acting on the flap 2 can ensure that the flap 2 automatically opens and remains in the open position. In addition, it can also be such that the force for closing the flap 2 is within an appropriate range at the same time, so that the user does not consume a lot of force to close the flap 2.

[0063] The cooking device of the embodiment of the present invention continuously monitors the elastic force of the elastic component 3 during use and can automatically correct the attenuated elastic force through the elastic force adjustment mechanism 4, thereby eliminating the problem that the flip cover 2 cannot be automatically opened or cannot be kept in the open position during use.

[0064] By converting the elastic force of the elastic component 3 into a pressure value and setting a target pressure, the elastic force for opening the flap 2 of the cooking device can be uniformly adjusted to a fixed value before leaving the factory, thereby ensuring consistent elastic force and consistent feel of the flap 2 before leaving the factory.

[0065] The control unit 5 in the embodiment of the present invention may include but is not limited to a microcontroller MCU, a programmable logic controller PLC, a field programmable gate array FPGA, an application specific integrated circuit ASIC, an application specific standard product ASSP, a system on chip SOC, etc.

[0066] In the embodiment of the present invention, the elastic component 3 may include various springs or other components capable of providing elastic force. For example, a torsion spring provides elastic force through a torsion arm, and a spiral spring provides elastic force through compression.

[0067] In some embodiments, see Figures 2 to 4 The flip cover 2 is rotatably connected to the base 1 through the rotating shaft 7. The elastic component 3 includes a torsion spring, which is sleeved on the rotating shaft 7. The first torsion arm 31 of the torsion spring abuts against the flip cover 2. The second torsion arm 32 of the torsion spring is connected to the elastic force adjustment mechanism 4. The elastic force adjustment mechanism 4 drives the second torsion arm 32 to rotate around the rotating shaft 7 to adjust the elastic force applied by the elastic component 3 on the flip cover 2. The torsion spring is sleeved on the rotating shaft 7, and the first torsion arm 31 acts on the flip cover 2 to provide elastic force, which can save the installation space of the elastic component 3, and the structure is simple and easy to assemble. The elastic force adjustment mechanism 4 is connected to the second torsion arm 32 of the torsion spring, drives the second torsion arm 32 to rotate, so that the compression of the torsion spring can be adjusted. When the compression of the torsion spring increases, the elastic force acting on the flip cover 2 increases, and when the compression of the torsion spring decreases, the elastic force acting on the flip cover 2 decreases. When the pressure detected by the pressure sensor 6 is less than the target pressure, the compression of the torsion spring can be increased through the elastic force adjustment mechanism 4. When the pressure detected by the pressure sensor 6 is greater than the target pressure, the compression of the torsion spring can be reduced through the elastic force adjustment mechanism 4.

[0068] The elastic force adjustment mechanism 4 in the embodiment of the present invention may be an electric drive device. The electric drive device may include, for example, an electric push rod, an electric screw, etc. The electric push rod can drive the second torsion arm 32 of the torsion spring to rotate by telescoping, thereby adjusting the compression amount of the torsion spring. The electric screw drives the nut to move along the screw, thereby driving the second torsion arm 32 of the torsion spring to rotate, thereby adjusting the compression amount of the torsion spring.

[0069] In some embodiments, see Figures 2 to 4 The elastic force adjustment mechanism 4 includes an electric drive assembly 41 and a displacement assembly 42. The electric drive assembly 41 is connected to the base 1; the displacement assembly 42 is connected to the base 1 and moves under the drive of the electric drive assembly 41. The displacement assembly 42 is connected to the second torsion arm 32, and the displacement assembly 42 drives the second torsion arm 32 to rotate around the rotating shaft 7. Figure 4, the red arrow in the figure indicates the direction of the rotation of the torsion spring, and the green arrow indicates the direction of the torsion spring away from the rotation. The electric drive assembly 41 is connected to the base 1, and the displacement assembly 42 is connected to the second torsion arm 32. When the electric drive assembly 41 drives the displacement assembly 42 to move, the displacement assembly 42 drives the second torsion arm 32 to rotate. When the second torsion arm 32 is consistent with the rotation direction of the torsion spring, the compression of the torsion spring increases, and the elastic force acting on the flip cover 2 increases. When the second torsion arm 32 is opposite to the rotation direction of the torsion spring, the compression of the torsion spring decreases, and the elastic force acting on the flip cover 2 decreases. When the elastic force adjustment mechanism 4 is an electric push rod, the electric drive assembly 41 may include a cylinder body, and the displacement assembly 42 may include a telescopic rod. The motor on the cylinder body provides power and converts the rotational motion of the motor into a linear reciprocating motion of the telescopic rod. The telescopic rod drives the second torsion arm 32 to rotate.

[0070] In some embodiments, see Figures 2 to 4 , the displacement assembly 42 is sleeved on the second torsion arm 32. The displacement assembly 42 is sleeved on the second torsion arm 32 to facilitate the connection between the two. The displacement assembly 42 can be slidably sleeved on the second torsion arm 32, or can be fixedly sleeved on the second torsion arm 32. The displacement assembly 42 is slidably sleeved on the second torsion arm 32, and when the second torsion arm 32 is driven to rotate, the displacement assembly 42 can slide along the second torsion arm 32 to adapt to the position change caused by the rotation of the second torsion arm 32.

[0071] In some embodiments, the displacement assembly 42 includes a connecting sleeve 421, which is sleeved on the second torsion arm 32. The displacement assembly 42 may include a connecting sleeve 421, which is connected to the second torsion arm 32 through the connecting sleeve 421. The elastic force adjustment mechanism 4 may select an existing mechanism capable of realizing linear reciprocating motion, which is combined with the connecting sleeve 421 to realize connection with the second torsion arm 32, without redesigning or modifying the elastic force adjustment mechanism 4. For example, when the elastic force adjustment mechanism 4 selects an electric push rod, the telescopic rod of the electric push rod is connected to the second torsion arm 32 through the connecting sleeve 421.

[0072] In some embodiments, the displacement assembly 42 includes a telescopic rod, which is connected to the electric drive assembly 41, and the telescopic rod can be extended or retracted into the electric drive assembly 41. In the exemplary embodiment, the displacement assembly 42 includes the elastic force adjustment mechanism 4 of the telescopic rod, which can be an electric push rod, an electric cylinder, or other devices capable of achieving linear reciprocating motion. The connecting sleeve 421 and the telescopic rod can be rotatably connected or fixedly connected. The connecting sleeve 421 is rotatably connected to the telescopic rod, and when the second torsion arm 32 is driven to rotate, the connecting sleeve 421 can rotate relative to the telescopic rod, so that the linear motion of the telescopic rod can adapt to the rotation of the second torsion arm 32.

[0073] In some embodiments, the displacement component 42 includes a screw and a nut. The screw is connected to the electric drive component 41 and rotates under the drive of the electric drive component 41. The nut is threadedly connected to the screw. The nut is used to connect to the second torsion arm 32. When the screw rotates, the nut moves along the screw, thereby driving the second torsion arm 32 to rotate. The connection sleeve 421 and the nut can be rotatably connected or fixedly connected. When the connection sleeve 421 is rotatably connected to the nut, when driving the second torsion arm 32 to rotate, the connection sleeve 421 can rotate relative to the nut, enabling the linear motion of the nut to adapt to the rotation of the second torsion arm 32.

[0074] In some embodiments, the cooking device according to the embodiment of the present invention further includes a pressure input component for adjusting the target pressure. In the embodiment of the present invention, the target pressure can be set at the factory to keep the feel of closing the flip cover 2 consistent. The target pressure can also be input by the user through the pressure input component. For people of different physical constitutions, including men, women, the elderly, and children, they can input the target pressure according to their own preferences to meet the personalized needs of the user.

[0075] In the embodiment of the present invention, the control unit 5 can store at least two alternative pressures of different sizes for selection. The user can select one of the alternative pressures as the target pressure through the pressure input component.

[0076] In some embodiments, the pressure input component can include selection buttons. Specifically, in implementation, each selection button can correspond to an alternative pressure. The user can operate the selection buttons by pressing, touching, etc. according to their own needs to select the corresponding alternative pressure as the target pressure. For example, the pressure input component can include three selection buttons, namely the gentle mode, the stable mode, and the strong mode. The alternative pressures corresponding to the selection buttons of the three modes are Fn = N1, Fn = N2, and Fn = N3 respectively, where N1 < N2 < N3. When the selection button for the gentle mode is selected, the corresponding N1 in this mode will be updated to the control unit 5 as the new target pressure, thus realizing multi-stage adjustment of the closing force of the flip cover 2 and meeting the different requirements of different people for the manual closing force of the flip cover 2. For example, Figure 4 the solid line position where the second torsion arm 32 is located and the dotted line positions on both sides can respectively correspond to different modes. The dotted line position pointed by the red arrow can correspond to the strong mode, the dotted line position pointed by the green arrow can correspond to the gentle mode, and the middle black solid line position can correspond to the stable mode.

[0077] Alternatively, there can be one selection button. At least two alternative pressures are sorted from small to large. Each time the selection button is operated, the alternative pressures are updated one by one from small to large or from large to small to the control unit 5 as the new target pressure, and the cycle repeats. For example, the alternative pressures are Fn = N1, Fn = N2, Fn = N3, where N1 < N2 < N3. When the current target pressure is N1, operating the selection button once changes the target pressure to N2. Operating the selection button again changes the target pressure to N3. At this time, if the selection button is operated again, the target pressure changes to N1, and the next cycle begins.

[0078] Or, there can be two selection buttons, one for increasing and the other for decreasing. Operating the selection button for increasing changes the target pressure from the current alternative pressure to the next alternative pressure in ascending order. Operating the selection button for decreasing changes the target pressure from the current alternative pressure to the next alternative pressure in descending order.

[0079] In some embodiments, the pressure input component can be a resistance knob, and the target pressure can be adjusted and assigned infinitely through the resistance knob. It can achieve the customization of continuous numerical values without gears, fully meeting the different requirements of each person for the manual closing force of the flip cover 2.

[0080] In some embodiments, the control unit 5 is configured to obtain the pressure exerted on the pressure sensor 6 when the flip cover 2 is in the open state; when the pressure is less than the target pressure, it issues an adjustment instruction to increase the pressure, and the adjustment instruction instructs the elastic force adjustment mechanism 4 to drive the second torsion arm 32 to rotate, so as to increase the compression amount of the torsion spring. Refer to Figure 4 In the cooking device according to the embodiment of the present invention, when the flip cover 2 is popped up when the device is powered on, the pressure sensor 6 continuously monitors the pressure value Fn exerted on it by the flip cover 2 and feeds the pressure value back to the control unit 5 in real time. The control unit 5 immediately compares the fed-back pressure value with the target pressure N. When Fn < N, it means that the elastic force of the torsion spring on the flip cover 2 is too small. The control unit 5 immediately sends an instruction to let the elastic force adjustment mechanism 4 drive the second torsion arm 32 to rotate in the same direction as the rotation direction. The compression amount of the torsion spring becomes larger, the force of the torsion spring on the flip cover 2 becomes larger, and the pressure value Fn exerted by the flip cover 2 on the pressure sensor 6 also becomes larger. When the control unit 5 monitors that the real-time fed-back pressure value Fn = N, the control unit 5 immediately sends an instruction to let the elastic force adjustment mechanism 4 stop working. Through automatic adjustment, the problem of consistent feel at the factory is solved, and the production error tolerance rate is improved. Moreover, users can adjust the target pressure through the pressure input component to meet personalized needs and improve the user experience.

[0081] In some embodiments, when the pressure is greater than the target pressure, it issues an adjustment instruction to decrease the pressure, and the adjustment instruction instructs the elastic force adjustment mechanism 4 to drive the second torsion arm 32 to rotate, so as to decrease the compression amount of the torsion spring. Refer to Figure 4When the cooking device of the embodiment of the present invention is powered on and the flap 2 is popped up, the pressure sensor 6 will continuously monitor the pressure value Fn exerted on it by the flap 2, and feed back the pressure value to the control unit 5 in real time. The control unit 5 will immediately compare the fed-back pressure value with the target pressure N. When Fn>N, it means that the elastic force exerted by the torsion spring on the flap 2 is too large. The control unit 5 immediately sends an instruction to let the elastic force adjustment mechanism 4 drive the second torsion arm 32 to rotate in the direction opposite to the rotation direction. The compression amount of the torsion spring becomes smaller, the force exerted by the torsion spring on the flap 2 becomes smaller, and the pressure value Fn exerted on the pressure sensor 6 by the flap 2 also becomes smaller. When the control unit 5 monitors the real-time feedback pressure value Fn=N, the control unit 5 sends an instruction to let the elastic force adjustment mechanism 4 stop working.
