Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically a novel inner plate lifting device and a cooking device using the lifting device. Background Technology

[0002] In the modern culinary field, people have increasingly higher requirements for the functions and performance of cooking equipment. As a result, cooking equipment with inner plate lifting functions, such as sugar-reducing rice cookers and lifting hot pots, has emerged. These devices are designed to achieve specific cooking effects by lifting the inner plate. For example, sugar-reducing rice cookers separate rice from sugar water by raising the inner plate to achieve the purpose of sugar reduction, while lifting hot pots separate ingredients from soup by raising the inner plate to avoid overcooking. However, there are some problems with the inner plate lifting devices of these existing cooking equipment that urgently need to be solved.

[0003] Traditional sugar-reducing rice cookers are mainly designed to meet people's demand for healthy eating. They separate rice from sugar by raising and lowering the inner plate. During operation, after the rice is cooked, the inner plate needs to rise to separate the rice from the sugar solution, thereby reducing the sugar content in the rice. However, the existing inner plate lifting device rises too slowly. During the rising process, the rice is soaked in the sugar solution for a long time. This means that even if the inner plate eventually rises and separates the rice, the rice still absorbs a lot of sugar, failing to achieve the ideal sugar reduction effect. Moreover, the long soaking time and slow rising process keep the rice in a high-temperature cooking state, which can easily lead to overcooking, affecting the taste and nutritional value.

[0004] For example, lifting hot pots also use an inner plate lifting device to lift the ingredients from the broth after they are cooked, preventing them from being overcooked in the broth. However, the current lifting hot pots have a slow inner plate lifting speed. As the ingredients slowly rise, they continue to absorb salt and seasonings from the broth and remain heated. This not only makes the ingredients too salty and worsens their taste, but also causes them to lose their original tenderness and nutrients due to overcooking, affecting the user's eating experience.

[0005] The existing inner plate lifting device has shortcomings in design and performance. The key problem of slow lifting speed seriously affects the actual use effect of cooking equipment such as sugar-reducing rice cookers and lifting hot pots, and cannot fully meet consumers' needs for high-quality cooking and healthy eating.

[0006] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0007] The aforementioned technical issues stem from the design and performance deficiencies of existing inner plate lifting devices, particularly the excessively slow lifting speed. This significantly impacts the actual performance of cooking appliances such as sugar-reducing rice cookers and lifting hot pots, failing to fully meet consumers' demands for high-quality cooking and healthy eating.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A novel inner disc lifting device includes independent drive components and lifting components. The lifting component includes a lifting housing, a lifting rod movably connected to the lifting housing, and an elastic medium between the lifting housing and the lifting rod. The lifting component also includes a locking assembly. The lifting rod has a locking part that can cooperate with the locking assembly to lock the lifting rod onto the lifting housing. The drive component has a first unlocking component, and the locking assembly has a second unlocking component corresponding to the first unlocking component. When unlocking is required, the drive component can drive the first unlocking component to sense the second unlocking component, causing the second unlocking component to drive the locking assembly to unlock, releasing the locking state of the lifting rod on the lifting housing, so that the elastic medium can quickly drive the lifting rod to move upward relative to the lifting housing.

[0010] As described above, in a novel inner disc lifting device, the locking assembly includes a rotating shaft, a rotating rod rotatably connected to the rotating shaft, and a buckle disposed on the rotating rod. The second unlocking member is disposed at the bottom of the rotating rod. The second unlocking member can drive the rotating rod to rotate on the rotating shaft, so that the portion of the rotating rod with the buckle swings, so that the buckle moves away from or closer to the locking part.

[0011] As described above, in a novel inner disc lifting device, the rotating rod includes a vertical section and a horizontal section, the horizontal section is located at the bottom of the vertical section, the second unlocking component is located at the bottom of the horizontal section, the buckle is provided on the top side wall of the vertical section, and the rotating shaft is rotatably connected to the vertical section.

[0012] In the novel inner plate lifting device described above, the locking assembly further includes a reset member, which enables the rotating rod to rotate toward the lifting housing so that the latch remains locked with the locking part.

[0013] As described above, in a novel inner disc lifting device, the reset component includes a reset housing, an elastic element disposed within the reset housing, and a reset head movably connected to the end of the reset housing. One end of the elastic element is connected to the bottom end of the reset head, and the top end of the reset head is connected to a rotating rod.

[0014] As described above, in a novel inner disc lifting device, the locking assembly further includes a limiting member that can limit the rotation amplitude of the rotating rod on the rotating shaft.

[0015] As described above, in a novel inner disc lifting device, the locking part includes a locking protrusion located on the outside of the lifting rod. When the lifting rod is in the locked state in the lifting housing, the locking protrusion abuts against the bottom of the buckle.

[0016] As described above, in a novel inner disc lifting device, the elastic medium includes an elastic spring or nitrogen gas.

[0017] As described above, in a novel inner disc lifting device, the driving component includes a drive motor, the first unlocking component includes a female magnetic component disposed at the output end of the drive motor, and the second unlocking component includes a female magnetic component.

[0018] A cooking device includes a pot body, an inner plate, and a novel inner plate lifting device as described in any of the above. The driving component is located on the bottom outer side of the pot body, and the lifting component is located on the bottom inner side of the pot body. When the locking component releases the locking state of the lifting rod on the lifting housing, the elastic medium can drive the lifting rod to move upward relative to the lifting housing, thereby causing the inner plate to rise inside the pot body.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model relates to a novel inner plate lifting device and a cooking device using the lifting device, belonging to the technical field of household appliances. The lifting device includes a driving component and a lifting component. The lifting component includes a lifting housing, a lifting rod movably connected to the lifting housing, and an elastic medium between the lifting housing and the lifting rod. The lifting component also includes a locking component. The lifting rod has a locking part, the driving component has a first unlocking component, and the locking component has a second unlocking component. When unlocking is required, the driving component can drive the first unlocking component to sense the second unlocking component, so that the second unlocking component drives the locking component to unlock, releasing the locking state of the lifting rod on the lifting housing. This allows the elastic medium to quickly drive the lifting rod to move upward relative to the lifting housing, thereby causing the inner plate to rise in the pot, preventing the food from continuing to cook with water in the pot, which could lead to overcooking or failure to remove sugar.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 6 As shown, a novel inner disc lifting device of this embodiment includes an independent drive component 1 and a lifting component 2. The lifting component 2 includes a lifting housing 21, a lifting rod 22 movably connected to the lifting housing 21, and an elastic medium 23 between the lifting housing 21 and the lifting rod 22. The lifting component 2 also includes a locking assembly 24, and a locking part 221 is provided on the lifting rod 22. The locking part 221 can cooperate with the locking assembly 24 to lock the lifting rod 22 onto the lifting housing 21. The drive component 1 is provided with a first unlocking component 11. The locking assembly 24 is provided with a second unlocking member 240 corresponding to the first unlocking member 11. When unlocking is required, the driving component 1 can drive the first unlocking member 11 and the second unlocking member 240 to sense each other, so that the second unlocking member 240 drives the locking assembly 24 to unlock, releasing the locking state of the lifting rod 22 on the lifting housing 21. This allows the elastic medium 23 to quickly drive the lifting rod 22 to move upward relative to the lifting housing 21, thereby causing the inner plate 5 to rise in the pot, preventing the food from continuing to cook with water in the pot, which could lead to overcooking or failure to remove sugar.

[0030] Specifically, during normal cooking, the locking component 24 cooperates with the locking part 221 on the lifting rod 22 to lock the lifting rod 22 onto the lifting housing 21. At this time, the elastic medium 23 is in a compressed energy storage state, and the inner plate 5 is located in a suitable cooking position inside the pot, allowing the ingredients to be cooked normally with water inside the pot.

[0031] When the cooking stage requires the inner plate 5 to be raised, the drive component 1 starts to work, driving the first unlocking component 11 to move and sense the second unlocking component 240 on the locking component 24. Through sensing, the second unlocking component 240 drives the locking component 24 to move, releasing the lock on the lifting rod 22.

[0032] Once the lock is released, the elastic medium 23, which was originally in a compressed state, quickly releases its elastic potential energy, driving the lifting rod 22 to move rapidly upward relative to the lifting housing 21. Since the lifting rod 22 is connected to the inner plate 5, it causes the inner plate 5 to rise rapidly inside the pot, separating the food from the water and preventing the food from continuing to cook in the water.

[0033] This novel inner plate lifting device utilizes the elastic potential energy stored in the elastic medium 23, which can quickly drive the lifting rod 22 and the inner plate 5 to rise after unlocking. This greatly increases the rising speed of the inner plate 5, effectively preventing the food from being in contact with water for a long time due to the slow rising process, thereby preventing the food from being overcooked or unable to remove sugar, and ensuring the taste and cooking effect of the food.

[0034] Furthermore, the drive component 1 and the lifting component 2 are set independently. This design makes the functions of the two components relatively independent. When one component fails, it will not easily affect the normal operation of the other component, thus improving the reliability and stability of the entire lifting device. At the same time, the independent design also makes it easier to maintain and replace the drive component 1 and the lifting component 2 separately, reducing maintenance costs and difficulties.

[0035] Unlocking is achieved through the sensing of the first unlocking component 11 and the second unlocking component 240. This unlocking method can be flexibly designed according to different needs. For example, electromagnetic induction can be used to achieve non-contact unlocking, reducing mechanical wear and improving the service life of the device; or the unlocking timing can be precisely controlled according to the control system of the cooking equipment to achieve intelligent cooking process.

[0036] The lifting device has a relatively simple structure, mainly consisting of a drive component 1, a lifting component 2, and its various components. The simple structure reduces manufacturing difficulty and production costs, which is conducive to the large-scale production and application of the product.

[0037] like Figures 1 to 6 As shown, the locking component 24 of this embodiment includes a rotating shaft 241, a rotating rod 242 rotatably connected to the rotating shaft, and a latch 243 disposed on the rotating rod 242. The second unlocking member 240 is disposed at the bottom of the rotating rod 242. The second unlocking member 240 can drive the rotating rod 242 to rotate on the rotating shaft 241, so that the part of the rotating rod 242 with the latch 243 swings, so that the latch 243 moves away from or closer to the locking part 221.

[0038] During normal cooking, the rotating rod 242 is in its initial position, and its latch 243 cooperates with the locking part 221 on the lifting rod 22 to firmly lock the lifting rod 22 onto the lifting housing 21. At this time, the elastic medium 23 is in a compressed state, the inner plate 5 is located in the appropriate cooking position inside the pot, and the food can be cooked normally.

[0039] When the inner plate 5 needs to be raised, the drive component 1 starts to work, driving the first unlocking component 11 to move. Since the second unlocking component 240 is located at the bottom of the rotating rod 242, the movement of the first unlocking component 11 will drive the second unlocking component 240 to move. Its movement will drive the rotating rod 242 to rotate around the rotating shaft 241. As the rotating rod 242 rotates, the part of the rotating rod 242 with the buckle 243 will swing, causing the buckle 243 to gradually move away from the locking part 221. When the buckle 243 is completely disengaged from the locking part 221, the locking state of the lifting rod 22 is released.

[0040] When it is necessary to lower and lock the inner plate 5 again, the lifting rod 22 can be pressed down on the lifting housing 21 to the designated position, so that the locking part 221 re-engages with the buckle 243, and the lifting rod 22 is locked on the lifting housing 21.

[0041] By rotating the lever 242 around the pivot 241, the latch 243 moves closer to or further away from the locking part 221, enabling reliable locking and unlocking of the lifting rod 22. In the locked state, the latch 243 and the locking part 221 are tightly engaged, ensuring that the lifting rod 22 is stably fixed on the lifting housing 21, preventing the inner plate 5 from rising unexpectedly during cooking. When unlocking, the rotation of the lever 242 can quickly disengage the latch 243 from the locking part 221, achieving rapid unlocking and meeting the need for the inner plate 5 to rise in a timely manner.

[0042] Furthermore, the locking assembly 24 mainly consists of a rotating shaft 241, a rotating rod 242, and a latch 243. The structure is relatively simple. This simple structure not only reduces manufacturing costs but also occupies little space, which is beneficial for installation and layout in the limited internal space of cooking equipment. At the same time, the simple structure also reduces the probability of failure and improves the reliability and stability of the entire device.

[0043] The first unlocking component 11 acts directly on the second unlocking component 240 at the bottom of the rotating rod 242. The swing of the buckle 243 is achieved by the rotation of the rotating rod 242 around the rotating shaft 241. This transmission method is direct and efficient, and can effectively transmit the driving force of the driving component 1 to the buckle 243, realize fast locking and unlocking actions, and improve the response speed of the device.

[0044] Because the locking assembly 24 has a simple structure and clear connection between its components, it is easy to maintain and adjust. If the buckle 243 or the rotating rod 242 is worn or damaged, it can be easily replaced. At the same time, parameters such as the rotation angle of the rotating rod 242 can be adjusted to ensure the fitting accuracy between the buckle 243 and the locking part 221 and to ensure the normal operation of the device.

[0045] like Figures 1 to 6 As shown, the rotating rod 242 in this embodiment includes a vertical section 2421 and a horizontal section 2422. The horizontal section 2422 is located at the bottom of the vertical section 2421. The second unlocking member 240 is located at the bottom of the horizontal section 2422. The buckle 243 is provided on the top side wall of the vertical section 2421. The rotating shaft 241 is rotatably connected to the vertical section 2421.

[0046] When the driving component 1 moves the first unlocking component 11, the second unlocking component 240 is located at the bottom of the horizontal section 2422. It applies a force to the horizontal section 2422. Since the rotating shaft 241 is rotatably connected to the vertical section 2421, this force will cause the rotating rod 242 to rotate around the rotating shaft 241. Specifically, the horizontal section 2422 is the point of application of the force. Under the push or pull of the second unlocking component 240, the entire rotating rod 242 is driven to rotate around the rotating shaft 241.

[0047] When the rotating rod 242 rotates around the rotating shaft 241, the vertical section 2421 will swing accordingly. Since the latch 243 is located on the top side wall of the vertical section 2421, the swing of the vertical section 2421 will cause the latch 243 to swing as well. When the rotating rod 242 rotates in one direction, the latch 243 will move closer to the locking part 221 to lock the lifting rod 22. When the rotating rod 242 rotates in the opposite direction, the latch 243 will move away from the locking part 221 to release the lock on the lifting rod 22.

[0048] The structural design of the horizontal segment 2422 and the vertical segment 2421 forms a lever-like structure. The second unlocking component 240 acts on the bottom of the horizontal segment 2422, while the latch 243 is located on the top side wall of the vertical segment 2421. According to the lever principle, under a small driving force, the latch 243 can generate a large swing amplitude through the rotation of the rotating rod 242, thereby achieving efficient force transmission. This means that the driving component 1 does not need to provide a large driving force to achieve reliable locking and unlocking between the latch 243 and the locking part 221, reducing the power requirements of the driving component 1 and saving energy.

[0049] This design allows the rotating rod 242 to better adapt to the internal space structure of the cooking equipment. The horizontal section 2422 is located at the bottom, which can make full use of the space at the bottom of the equipment and avoid interference with other components. The vertical section 2421 can extend vertically, placing the buckle 243 at a suitable height position so as to effectively cooperate with the locking part 221. This spatial layout allows the entire locking assembly 24 to be installed more compactly in the equipment, improving the utilization rate of the internal space of the equipment.

[0050] Furthermore, the horizontal section 2422 and the vertical section 2421 of the rotating rod 242 have relatively independent structures, which facilitates manufacturing and installation. During installation, each part can be assembled and adjusted separately, improving the convenience and accuracy of installation. At the same time, when maintenance or replacement of parts of the locking component 24 is required, the clear structure makes operation easier. For example, if the buckle 243 is damaged, the vertical section 2421 can be easily disassembled and replaced without affecting the normal operation of other parts. In other embodiments, the horizontal section 2422, the vertical section 2421, and the buckle 243 are integrally formed structures, and a suitable design can be selected according to actual needs.

[0051] Specifically, the combined structure of the vertical section 2421 and the horizontal section 2422 increases the overall stability of the rotating rod 242. The horizontal section 2422 provides some support, making the rotating rod 242 more stable during rotation and reducing swaying and vibration. This helps improve the fitting accuracy between the buckle 243 and the locking part 221, ensuring the reliability of locking and unlocking actions.

[0052] Preferably, the rotating rod 242 is L-shaped. The unique shape of the L-shaped rotating rod 242 enables effective force conversion and transmission during operation. When the second unlocking component 240 applies force to the transverse section 2422, the horizontal force on the transverse section 2422 is converted into the swinging motion of the vertical section 2421 and the latch 243 due to the rotation of the rotating rod 242 around the pivot 241. This force conversion allows the horizontal driving force originally acting at the bottom to drive the latch 243 located at the top to swing, thereby completing the locking and unlocking operation of the lifting rod 22.

[0053] The L-shaped lever 242 can be regarded as a deformed lever, with the pivot 241 as the fulcrum. The second unlocking component 240 applies force at the horizontal section 2422, forming the power arm. The vertical section 2421 where the buckle 243 is located forms the resistance arm. According to the lever principle, the length ratio between the power arm and the resistance arm determines the amplification or reduction effect of the force. By reasonably designing the dimensions of the L-shaped lever 242, the lengths of the power arm and the resistance arm can be adjusted to achieve a sufficiently large swing amplitude of the buckle 243 under a small driving force to achieve the purpose of locking and unlocking.

[0054] like Figures 1 to 6 As shown, the locking component 24 in this embodiment also includes a reset component 244, which can rotate the rotating rod 242 toward the lifting housing 21 so that the buckle 243 is kept locked with the locking part 221.

[0055] Specifically, the reset member 244 is typically an elastic component, such as a spring. When the locking assembly 24 is in the normal locked state, the reset member 244 is in a certain elastic deformation state, storing elastic potential energy. When the second unlocking member 240 applies an external force to the rotating rod 242, causing the rotating rod 242 to rotate around the rotating shaft 241 in a direction away from the lifting housing 21, the latch 243 separates from the locking part 221, realizing the unlocking operation. During this process, the elastic deformation of the reset member 244 further increases, and the elastic potential energy increases.

[0056] When the second unlocking component 240 removes the external force on the rotating rod 242, the reset component 244 begins to release the stored elastic potential energy, converting the elastic potential energy into the kinetic energy of the rotating rod 242, pushing the rotating rod 242 to rotate towards the lifting housing 21, so that the buckle 243 and the rotating rod 242 return to their initial positions.

[0057] From a force perspective, the reset member 244 applies an elastic force to the rotating rod 242 pointing towards the lifting housing 21. In the locked state, this elastic force is balanced with other forces on the rotating rod 242 (such as the friction between the latch 243 and the locking part 221), keeping the rotating rod 242 stably in the locked position. When an external force is applied to unlock, the external force overcomes the elastic force of the reset member 244, causing the rotating rod 242 to rotate and unlock. After the external force is removed, the elastic force of the reset member 244 takes the lead again, pushing the rotating rod 242 and the latch 243 back to the initial position, re-establishing the balance of forces.

[0058] The presence of the reset component 244 enables the locking component 24 to automatically reset. After the unlocking operation is completed, the rotating rod 242 can automatically return to its initial position under the action of the reset component 244 without manual intervention.

[0059] Preferably, the reset member 244 enables the buckle 243 to always remain locked with the locking part 221. During the operation of the cooking equipment, it may be affected by external factors such as vibration and impact. Without the reset member 244, the buckle 243 may accidentally disengage from the locking part 221 due to these external disturbances, resulting in unstable position of the lifting rod 22. The elastic force applied by the reset member 244 can effectively resist these external disturbances, ensure the tight fit between the buckle 243 and the locking part 221, and improve the stability and reliability of the locking.

[0060] For users, the automatic reset function of the reset component 244 simplifies the operation process. Users only need to perform the unlocking operation to adjust the position of the lifting rod 22 without worrying about subsequent locking issues. After the adjustment is completed, the locking component 24 will automatically return to the initial state, making the operation of the device simpler and easier to understand, lowering the user's threshold and improving the user experience.

[0061] like Figures 1 to 6 As shown, the reset component 244 in this embodiment includes a reset housing 2441, an elastic member 2442 disposed in the reset housing 2441, and a reset head 2443 movably connected to the end of the reset housing 2441. One end of the elastic member 2442 is connected to the bottom end of the reset head 2443, and the top end of the reset head 2443 is connected to the rotating rod 242.

[0062] Specifically, the elastic element 2442 is usually a spring or other elastic component. When the second unlocking component 240 applies an external force to the rotating rod 242, causing the rotating rod 242 to rotate around the rotating shaft 241 in a direction away from the lifting housing 21, the reset head 2443 connected to the rotating rod 242 will move towards the inside of the reset housing 2441 under the drive of the rotating rod 242. During this process, the elastic element 2442 is compressed, and elastic potential energy is stored inside the elastic element 2442.

[0063] When the first unlocking member 11 removes the external force on the rotating rod 242 with the second unlocking member 240, the elastic member 2442 begins to release the stored elastic potential energy. The elastic member 2442 restores its deformation and pushes the reset head 2443 to move outside the reset housing 2441. Since the top of the reset head 2443 is connected to the rotating rod 242, the movement of the reset head 2443 will drive the rotating rod 242 to rotate closer to the lifting housing 21 until the latch 243 is reset to the initial position.

[0064] Specifically, the reset housing 2441 provides a stable working space for the elastic element 2442 and the reset head 2443. During the movement of the reset head 2443, the reset housing 2441 guides the reset head 2443, ensuring that the reset head 2443 moves in a predetermined direction, preventing the elastic element 2442 from shifting or twisting during compression and recovery, thus ensuring that the elastic element 2442 can work normally. At the same time, the reset housing 2441 can also protect the elastic element 2442 from the influence of external dust, debris, etc., extending the service life of the elastic element 2442.

[0065] The combined design of the reset housing 2441, the elastic element 2442, and the reset head 2443 can precisely control the reset process of the rotating rod 242. The guiding effect of the reset housing 2441 ensures that the moving direction of the reset head 2443 is accurate. The elastic characteristics of the elastic element 2442 can be precisely adjusted according to the design requirements, thereby precisely controlling the reset speed and force of the rotating rod 242, and improving the working accuracy and reliability of the locking assembly 24.

[0066] The reset housing 2441 provides a stable structural support for the entire reset component 244. It integrates the elastic element 2442 and the reset head 2443 into a relatively independent module, reducing the interference of external factors on the operation of the reset component 244. During the operation of the cooking equipment, even if it is affected by vibration, impact, etc., the reset housing 2441 can ensure the normal operation of the elastic element 2442 and the reset head 2443, thus enhancing the structural stability of the locking component 24.

[0067] This modular design makes the maintenance and replacement of the reset component 244 more convenient. If the elastic element 2442 is damaged or its elastic performance decreases, the elastic element 2442 can be easily replaced simply by opening the reset housing 2441. At the same time, the connection between the reset head 2443 and the rotating rod 242 is usually easy to disassemble and install, reducing the difficulty and cost of equipment maintenance.

[0068] Precise reset control and stable structural design help improve the safety of cooking equipment. During the use of the equipment, the locking component 24 can reliably achieve the unlocking and locking functions, ensuring the stable position of the lifting rod 22.

[0069] like Figures 1 to 6 As shown, the locking component 24 in this embodiment also includes a limiting member 245, which can limit the rotation amplitude of the rotating rod 242 on the rotating shaft 241.

[0070] Specifically, the limiting member 245 is usually set on the rotation path of the rotating rod 242. It can be a physical stop or a structure with a specific shape. When the rotating rod 242 rotates around the rotating shaft 241, as the rotation amplitude increases, the rotating rod 242 will come into contact with the limiting member 245. Once the rotating rod 242 comes into contact with the limiting member 245, the limiting member 245 will prevent the rotating rod 242 from continuing to rotate, thereby limiting the rotation amplitude of the rotating rod 242.

[0071] During the operation of the locking component 24, the reset component 244 will reset the rotating rod 242. The limiting component 245 can ensure that the rotating rod 242 will not rotate excessively during the reset process. When the rotating rod 242 rotates to the appropriate position, the limiting component 245 will limit it to ensure that the buckle 243 can be accurately locked with the locking part 221 or reset to the initial position.

[0072] By limiting the rotation amplitude of the rotating rod 242, the limiting member 245 can ensure the fitting accuracy between the latch 243 and the locking part 221. In the locked state, the rotation amplitude of the rotating rod 242 is limited to a suitable range, so that the latch 243 can accurately engage with the locking part 221, ensuring the reliability of the lock. Alternatively, it can ensure that the latch 243 is reset to the initial position, so that when the lifting rod 22 is reset and lowered to the locked position, the locking part 221 and the latch 243 can be precisely engaged and locked.

[0073] The limiting component 245 restricts the rotation range of the rotating rod 242, making the structure of the locking assembly 24 more stable. During equipment operation, even if it is affected by external forces such as vibration and impact, the limiting component 245 can ensure that the rotating rod 242 rotates within a reasonable range, avoiding structural loosening or deformation caused by excessive rotation of the rotating rod 242, and enhancing the overall structural stability of the locking assembly 24.

[0074] Preferably, the limiting member 245 includes a limiting housing, and the rotating shaft 241 and the reset member 244 are disposed inside the limiting housing. When the bottom of the buckle 243 is close to or abuts the top of the limiting housing, the buckle 243 can accurately lock with the locking part 221 or reset to the initial position.

[0075] Specifically, the limiting housing provides a relatively stable installation space for the rotating shaft 241 and the reset component 244. When the rotating rod 242 rotates around the rotating shaft 241, the latch 243 will move accordingly. As the rotation proceeds, the bottom of the latch 243 gradually approaches or abuts against the top of the limiting housing. At this time, the limiting housing plays a positioning role. It clearly defines the rotation position of the rotating rod 242 through physical contact, so that the latch 243 can accurately reach the precise position required to lock with the locking part 221 or reset to the initial position.

[0076] The reset component 244 stores elastic potential energy during the rotation of the rotating rod 242. When the external force is removed, the reset component 244 releases the elastic potential energy to reset the rotating rod 242. The limiting housing and the reset component 244 cooperate with each other. During the reset process, the limiting housing can ensure that the rotating rod 242 will not rotate excessively due to the action of the reset component 244, ensuring that the buckle 243 accurately returns to the initial position so that the locking operation can be performed smoothly next time.

[0077] By precisely limiting the position of the buckle 243 with the limiting housing, a precise fit between the buckle 243 and the locking part 221 can be ensured.

[0078] The limiting housing houses the rotating shaft 241 and the reset component 244, providing them with a stable working environment. The structure of the limiting housing itself can enhance the overall rigidity of the locking assembly 24, reduce the loosening or displacement of components caused by external impact or vibration, and improve the reliability and durability of the locking assembly 24.

[0079] The rotating shaft 241 and the reset component 244 are integrated into the limiting housing to form a relatively independent module. During the assembly of the cooking equipment, this module can be installed in the corresponding position as a whole, which simplifies the assembly process and improves production efficiency. At the same time, if the locking component 24 fails during equipment maintenance, the entire module can be easily disassembled for inspection or replacement, reducing maintenance difficulty and cost.

[0080] Preferably, the limiting housing is provided with a rotation hole for assembling the rotating shaft 241 and an assembly hole for assembling the reset housing 2441. The reset housing 2441 and the assembly hole can be connected by means of thread, screw connection or snap connection, and a suitable design can be selected according to actual needs.

[0081] Preferably, the top of the reset head 2443 abuts against one side of the vertical section 2421, and a suitable design can be selected according to actual needs.

[0082] Preferably, the bottom end of the reset head 2443 is provided with an abutment plate, one end of the elastic element 2442 (i.e., spring) abuts against the abutment plate, and the other end abuts against the end of the reset housing 2441. A suitable design can be selected according to actual needs.

[0083] Preferably, in other embodiments, the limiting member 245 may also be a limiting post or limiting protrusion disposed below the buckle 243, and a suitable design may be selected according to actual needs.

[0084] like Figures 1 to 6As shown, the locking part 221 of this embodiment includes a locking protrusion provided on the outside of the lifting rod 22. When the lifting rod 22 is in the locked state in the lifting housing 21, the locking protrusion abuts against the bottom of the buckle 243.

[0085] When the latch 243 reaches the appropriate position, its bottom abuts against the top of the locking protrusion. This abutting state generates a mutual force, preventing the lifting rod 22 from moving further up or down, thereby fixing the lifting rod 22 in the current position and locking the corresponding part of the cooking equipment.

[0086] When unlocking is required, an external force is applied to the rotating rod 242 to make it rotate in the opposite direction around the rotating shaft 241, causing the buckle 243 to move away from the locking protrusion, releasing the state of the bottom of the buckle 243 against the locking protrusion. At this time, the lifting rod 22 is no longer restricted by the buckle 243 and can move freely up and down in the lifting housing 21 to realize the unlocking operation.

[0087] The design of the locking protrusion abutting against the bottom of the buckle 243 provides a stable and reliable locking force. During the cooking process, the cooking equipment may be affected by various factors such as vibration and pressure changes. This direct abutting method can effectively resist these external interferences and ensure that the lifting rod 22 will not move accidentally, thereby ensuring the sealing and stability of components such as the cooking chamber and providing a safe and reliable environment for the cooking process.

[0088] The structure of this locking method is relatively simple. It only requires setting a locking protrusion on the outside of the lifting rod 22 and setting a corresponding buckle 243 in the locking component 24. Compared with some complex locking mechanisms, its manufacturing and installation costs are lower, and it is easier to achieve mass production in actual production. At the same time, the simple structure also reduces the probability of failure and improves the reliability and stability of the equipment.

[0089] For users, this locking method is very convenient to operate. During the locking and unlocking process, you only need to rotate the lever 242 to control the position of the buckle 243. There is no need to perform complicated operation steps. Whether it is the elderly or children, they can easily complete the locking and unlocking of the device, which improves the user experience.

[0090] Because the locking part 221 and the buckle 243 have a relatively simple structure, maintenance personnel can easily inspect and repair them when the equipment malfunctions. If the locking protrusion or buckle 243 is worn or damaged, it can also be easily replaced, reducing the maintenance cost and difficulty of the equipment.

[0091] Specifically, the buckle 243 in this embodiment is also provided with a guide slope 2431 at the top. When the locking component 24 is in the normal locking state, the buckle 243 and the locking part 221 are in the locked state. When the second unlocking component 240 applies an external force to the rotating rod 242, causing the rotating rod 242 to rotate around the rotating shaft 241 in a direction away from the lifting housing 21, the buckle 243 and the locking part 221 are separated, realizing the unlocking operation. When the second unlocking component 240 removes the external force on the rotating rod 242, the reset component 244 pushes the rotating rod 242 to rotate in a direction closer to the lifting housing 21, so that the buckle 243 and the rotating rod 242 return to the initial position. At this time, the limit component 245 restricts the buckle 243 to the initial position.

[0092] When it is necessary to reset the lifting rod 22 to the initial position of the lifting housing 21, the user can press the lifting rod 22 by hand until the lifting rod 22 descends to the bottom of its locking part 221 and abuts against the guide slope 2431. Continuing to apply force, the locking part 221 will force the latch 243 through the guide slope 2431, so that the locking part 221 slides relative to the guide slope 2431, forcing the latch 243 to drive the rotating rod 242 to rotate away from the lifting rod 22, until the locking part 221 moves to the end of the guide slope 2431 and to the bottom of the latch 243. At this point, the reset member 244 is elastically released, driving the rotating rod 242 back to the initial position, thereby driving the latch 243 back to the initial position and placing it above the locking part 221 to achieve locking with the locking part 221.

[0093] Unlocking can be achieved by applying external force to the rotating rod 242 through the second unlocking component 240. The operation is simple and direct. After the external force is removed, the reset component 244 can automatically push the rotating rod 242 and the latch 243 back to the initial position, and the limiting component 245 can restrict them to the initial position without additional adjustment, which facilitates subsequent locking operations.

[0094] Users only need to manually press the lifting rod 22, and the guide slope 2431 will guide the buckle 243 to automatically complete the process of avoiding and relocking. There are no complicated operation steps, which reduces the difficulty of use and improves the convenience of operation.

[0095] The design of the guide ramp 2431 is key to the entire locking and resetting process. It allows the locking part 221 to naturally push the buckle 243 to move during the descent, realizing the function of automatic unlocking and relocking by utilizing mechanical principles, thus avoiding the trouble of precise manual operation.

[0096] The cooperation between the reset component 244 and the limiting component 245 ensures that the rotating rod 242 and the latch 243 can accurately return to their initial positions and remain stable, thereby improving the reliability and stability of the entire locking assembly and reducing locking failures caused by positional deviations.

[0097] During normal use, the locking assembly can reliably lock the lifting rod 22 in the required position, preventing it from moving accidentally and ensuring the normal operation and safety of the equipment.

[0098] During the unlocking and reset operations, the various components work closely and in an orderly manner, reducing the risk of accidental unlocking or locking abnormalities caused by misoperation or external interference, and further improving the safety of the equipment.

[0099] This structure is relatively simple, with each component having a clearly defined function. It is easy to inspect and repair when a fault occurs. If a component (such as reset component 244, limit component 245, etc.) is damaged, it is also relatively easy to replace, which reduces the maintenance cost and repair difficulty of the equipment.

[0100] like Figures 1 to 6 As shown, the elastic medium 23 in this embodiment includes an elastic spring or nitrogen gas. When the spring is used as the elastic medium, the lifting rod 22 moves downward in the lifting housing 21 under the action of external force, which will compress the elastic spring. After the elastic spring is compressed, the distance between its internal molecules changes, generating elastic potential energy. As the amount of compression increases, the elastic force generated by the spring will also increase accordingly.

[0101] When the external force is removed, the elastic potential energy stored in the elastic spring begins to be released, the spring returns to its original deformation, and the resulting elastic force pushes the lifting rod 22 to move away from the lifting housing 21, so that the lifting rod 22 returns to its initial position or reaches the corresponding extended state.

[0102] When nitrogen is used as an elastic medium, the lifting rod 22 descends in the lifting housing 21, the space inside the housing becomes smaller, and the nitrogen is compressed. When the external force is removed, the compressed nitrogen, due to its high pressure, will push the lifting rod 22 outward, increasing the space inside the housing. The pressure of the nitrogen gradually decreases, returning to its original state, thus realizing the rebound of the lifting rod 22.

[0103] Whether it's an elastic spring or nitrogen gas, both can act as a buffer during the movement of the lifting rod 22. When the lifting rod 22 is impacted by an external force, the elastic medium will first absorb some of the energy and convert it into elastic potential energy or gas internal energy, thereby reducing the impact on other parts of the equipment, reducing the risk of component damage, and extending the service life of the equipment.

[0104] The elastic properties of the elastic medium can be adjusted by selecting different specifications of elastic springs (such as different stiffness coefficients) or by adjusting the initial pressure of nitrogen gas to meet different application requirements.

[0105] like Figures 1 to 6 As shown, the driving component 1 in this embodiment includes a driving motor, the first unlocking component 11 includes a female magnetic component disposed at the output end of the driving motor, and the second unlocking component 240 includes a female magnetic component. Preferably, the female magnetic component is a magnet or similar structure, and the female magnetic component is a solenoid valve, electromagnet, or similar structure. When the female magnetic component is an electromagnet, the driving motor rotates to energize it, thereby driving the female magnetic component to move. When the female magnetic component is a solenoid valve or a magnet, the driving motor (or a ground motor) can be used to drive the solenoid valve or magnet to approach the female magnetic component, thereby driving the female magnetic component to move. All of the above can be implemented by a microcontroller.

[0106] Specifically, the drive motor starts working and rotates. During its rotation, the electromagnet is energized through a specific circuit structure. This is achieved by using the electrical signal generated when the motor rotates or by triggering a circuit switch through the mechanical structure driven by the motor, so that current flows into the electromagnet.

[0107] When an electromagnet is energized, according to Ampere's law, the current will generate a magnetic field in the coil of the electromagnet, forming a magnetic field environment with a certain strength and direction around the electromagnet.

[0108] Because the sub-magnetic components (such as magnets) are magnetic, under the influence of the magnetic field generated by the electromagnet, according to the interaction law between magnets (like poles repel and unlike poles attract), the sub-magnetic components will be subjected to magnetic force and move, thereby unlocking.

[0109] A microcontroller can precisely control the rotation of a drive motor, including controlling the motor's speed, direction of rotation, and rotation time. By adjusting the motor's operating state, it can indirectly control the energization of the electromagnet, thereby precisely controlling the action of the sub-magnetic components and realizing the system's automated and intelligent control.

[0110] In other embodiments, the drive motor (stepper motor) starts and runs according to the program set by the microcontroller, driving the solenoid valve or magnet to approach the sub-magnetic component through a mechanical transmission structure (such as gears, chains, etc.).

[0111] As the solenoid valve approaches the sub-magnetic component, its internal electromagnetic coil is energized, generating a magnetic field. When the solenoid valve gets close enough to the sub-magnetic component to a certain distance, the sub-magnetic component will be affected by the magnetic field of the solenoid valve and will act according to the interaction law between magnets.

[0112] The microcontroller can also control the drive motor, precisely control the motor's operation, and thus accurately control parameters such as the distance, speed, and time when the solenoid valve or magnet approaches the sub-magnetic component, achieving precise control of the sub-magnetic component's movement and meeting different system operating requirements.

[0113] By utilizing the magnetic force between magnetic components to achieve drive and motion transmission, the direct physical contact in traditional mechanical transmission methods is avoided. This reduces mechanical wear and friction, lowers energy loss, and extends the service life of the equipment. It also reduces noise and vibration caused by mechanical contact, improving the operational stability and comfort of the equipment.

[0114] A microcontroller can precisely control the drive motor, thereby flexibly controlling the working state of the parent magnetic component (such as the energization of the electromagnet, the movement of the solenoid valve or magnet), thus achieving precise control of the action of the child magnetic components. The action mode, force, and timing parameters of the child magnetic components can be easily adjusted according to different working scenarios and needs, improving the adaptability and intelligence of the equipment.

[0115] like Figures 1 to 6 As shown, a cooking device in this embodiment includes a pot body, an inner plate, and a novel inner plate lifting device as described above. The driving component 1 is located on the outer bottom of the pot body, and the lifting component 2 is located on the inner bottom of the pot body. When the locking component 24 releases the locking state of the lifting rod 22 on the lifting housing 21, the elastic medium 23 can drive the lifting rod 22 to move upward relative to the lifting housing 21, thereby causing the inner plate 5 to rise inside the pot body. This prevents the food from continuing to cook with water in the pot, which could lead to overcooking or failure to remove sugar. The working principle and advantages of this design are:

[0116] When the cooking equipment detects a specific cooking stage or meets preset conditions (such as reaching the set cooking time, temperature, etc.), the control system will issue a command to activate the locking component 24, releasing the locking state of the lifting rod 22 on the lifting housing 21.

[0117] After the locking state is released, the elastic medium 23, which is in a compressed or stored state, begins to release elastic potential energy. The elastic medium (such as a spring) will exert an upward force on the lifting rod 22. Since the lifting rod 22 is no longer locked at this time, the lifting rod 22 will move upward relative to the lifting housing 21 under the drive of the elastic medium 23.

[0118] As the lifting rod 22 moves upward, the inner plate 5 connected to the lifting rod 22 will rise inside the pot along with the lifting rod 22. After the inner plate 5 rises, the food originally placed on the inner plate 5 will leave the water surface in the pot, thus preventing the food from continuing to soak in the water for cooking.

[0119] Different ingredients have their optimal cooking time and temperature during the cooking process. If ingredients are soaked in water for a long time and continue to cook, they are easily overcooked, affecting their taste and nutritional value. By raising the inner plate 5, the ingredients can be separated from the water in time, stopping the cooking process and ensuring the taste and quality of the ingredients, so that they reach their best eating state.

[0120] For some ingredients that require sugar removal (such as rice), some of the sugar in the ingredients can dissolve into the water during the cooking process. When the inner plate 5 rises, the ingredients are separated from the water, reducing the reabsorption of sugar from the water by the ingredients, thus achieving the sugar removal effect to a certain extent and meeting the health needs of some people with special requirements for sugar intake.

[0121] This design makes the cooking process more flexible and controllable. Users can adjust the parameters of the cooking equipment according to the characteristics of different ingredients and their personal taste preferences, controlling the timing and duration of the inner plate's ascent to achieve diverse cooking methods, increasing the fun and choice in cooking.

[0122] This design utilizes the elastic potential energy of the elastic medium 23 to drive the inner disk 5 upward. The structure is relatively simple, requiring no complex power system or transmission mechanism. This reduces the probability of mechanical failure, improves the reliability and stability of the equipment, and lowers maintenance costs and repair difficulty.

[0123] The cooking equipment can automatically unlock the locking component 24 according to preset conditions, allowing the inner plate 5 to rise without manual intervention from the user. This improves the automation level of cooking, makes it more convenient for users, and is especially suitable for busy modern lifestyles.

[0124] Preferably, the cooking device further includes a base, and the drive component 1 is located inside the base.

[0125] Specifically, the drive component 1 and electrical components are located entirely on the outside of the pot body, while the lifting component 2 is located on the inside of the pot body. This avoids the risk of the motor directly contacting the internal environment of the cooking device and eliminates safety hazards such as water leakage and electric leakage. It is particularly suitable for application scenarios that require direct contact with liquids, such as lifting hot pots, sugar-reducing rice cookers, and pressure cookers.

[0126] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
