[0038] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] In the use of cooking equipment, besides technical issues such as the recovery of waste liquid accumulated on the lid and the extraction of oil fumes, another noteworthy technical issue concerns the cleaning process inside the pot. For example, in the current use of automatic woks, after the customer finishes cooking, there is a large amount of residual oil and residue on the inner cavity of the pot and the lid, requiring manual cleaning by the customer. To address this, this application embodiment also provides a cleaning device, which includes a spatula assembly suitable for both cooking and cleaning the inner cavity of the pot.

[0041] like Figure 3As shown, the cooking device 1 provided in this application embodiment includes a pot body 310, a pot lid 20, and a spatula assembly 40. In some embodiments of this application, the cooking device 1 may also include a base 10 for supporting the pot body 310. The lid 220 of the pot lid 20 is driven by a cantilever 210 to close or lift on the pot body 310. When the lid 220 is closed on the pot body 310, the inner cavity of the pot body 310 forms a sealed space for cooking ingredients, i.e., a cooking cavity. The spatula assembly 40 is disposed on the pot lid 20 and extends into the inner cavity of the pot body 310 when the pot lid 20 is closed on the pot body 310. It is used to stir the ingredients and, after the cooking process is completed, to scrub the bottom surface 313, the inner wall surface 314 of the pot body 310, and the inner surface 221 of the pot lid 20. In addition, in some embodiments of this application, the cooking device 1 may be a smart Internet of Things terminal device including a control module. The control module may be, but is not limited to, a computer-readable storage medium containing a computer program that, when executed, enables the implementation of the steps in the self-cleaning method and control method of the cooking device provided in the embodiments of this application. Therefore, the embodiments of this application can be provided as methods, systems, or computer program products; they can take the form of a completely hardware embodiment, a completely software embodiment, or an embodiment combining software and hardware aspects. It can also take the form of a computer program product implemented on one or more computer-readable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code. In a typical configuration, the computing device includes one or more processors (CPUs), input / output interfaces, network interfaces, and memory. Memory may include non-persistent memory in computer-readable media, random access memory (RAM), and / or non-volatile memory, such as read-only memory (ROM) or flash RAM. The above are merely examples illustrating the possible forms and compositions of the control module, and are not intended to limit it.

[0042] In the above-described embodiments of this application, the control module can drive the cantilever 210 of the lid 20 to swing, so that the lid 220 can be opened and closed on the pot body 310, and drive the spatula assembly 40 to move. The control module can adaptively adjust the movement mode of the spatula assembly 40 according to the menu content intelligently selected by the user or the control module before the cooking device 1 is started, such as the menu stored in the cooking device 1 or the menu obtained from the Internet of Things. This allows the spatula of the spatula assembly 40 to be used in combination with multiple modes such as revolution, rotation and lifting within the pot body 310, so as to achieve a 360-degree self-cleaning operation within the pot body 310 without dead angles.

[0043] Please refer to Figures 4 to 7The spatula assembly 40 is located in the cooking chamber and includes a drive device 410, a spatula 420, a transmission device 430, and a lifting device 440. The drive device 410 is driven to the spatula 420 to drive the spatula 420 to rotate; for example, the drive device 410 includes a rotating mechanism and a first power output shaft 412. The rotating mechanism includes a rotating motor 411 and a pulley. The rotating motor 411 is disposed in the spatula mounting portion 2123 at the front end of the cantilever 210. One end of the first power output shaft 412 is connected to the rotating motor 411 via the pulley, and the other end passes through the cover 220 and is connected to the spatula 420 on one side of the inner surface 221 of the cover 220. The control module is electrically connected to the drive device 410 and the lifting device 440 respectively, and is used to selectively start the movement of the drive device 410 and / or the lifting device 440 according to the cooking conditions, and adaptively control the rotation speed and / or lifting speed of the spatula 420. For example, starting the rotary motor 411 drives the first power output shaft 412 to rotate, thereby causing the spatula 420 to revolve within the pot body 310. During this process, the drive device 410 simultaneously starts the transmission device 430 to drive the spatula 420 to rotate within the pot body 310. This will be further explained below.

[0044] The lifting device 440 is located on the cover 220 and is driven to connect with the spatula 420. The lifting device 440 can drive the spatula 420 to move up and down relative to the pot body 310 between a first predetermined position and a second predetermined position.

[0045] When the spatula 420 is in the first predetermined position, it is in close contact with the inner surface of the lid 220. Driven by the drive device 410, the spatula 420 can clean the inner surface of the lid 220 at the first predetermined position. When the spatula 420 is in the second predetermined position, it disengages from the inner surface of the lid 220. For example, the first predetermined position can be the highest position where the spatula 420 is raised, and the second predetermined position can be the lowest position where the spatula 420 is lowered.

[0046] When the spatula 420 is in the first predetermined position, it has a clearance fit or an interference fit with the inner wall surface 314 of the pot body 310, and a clearance fit or an interference fit with the bottom surface of the pot body 310. When the spatula 420 is in the second predetermined position, it has an interference fit with the inner wall surface 314 of the pot body 310, and an interference fit with the bottom surface of the pot body 310. When the spatula 420 is in the second predetermined position, driven by the driving device 410, it can clean the bottom surface and inner wall surface 314 of the pot body 310. When the spatula 420 is in the second predetermined position, it has an interference fit with both the bottom surface and inner wall surface 314 of the pot body 310, and can clean both surfaces in the first predetermined position. Therefore, at least the following can be achieved: when the spatula 420 rises to the first predetermined position, it cleans the lid 220; when the spatula 420 descends to the second predetermined position, it cleans the pot 310. This allows the spatula 420 to clean the cooking container while preventing it from constantly contacting the lid 220 and pot 310, thus avoiding continuous wear and tear and extending its lifespan. The spatula 420 includes a support 421, a stirring spatula 422, and an auxiliary spatula 423. The support 421 is connected to the lid 220. The stirring spatula 422 and the auxiliary spatula 423 can be respectively mounted on the support 421, and both the stirring spatula 422 and the auxiliary spatula 423 can rotate relative to the lid 220. The rotation axis of the stirring spatula 422 is parallel to and spaced apart from the rotation axis of the auxiliary spatula 423. Furthermore, the rotation axis of the auxiliary spatula 423 can coincide with the central axis of the lid 220. In other words, the rotation center of the auxiliary shovel 423 is located at the rotation center of the cover 220. When the auxiliary shovel 423 rotates, it can clean the inner surface of the cover 220 evenly along the circumferential direction of the cover 220.

[0047] For example, the bracket 421 is provided with spaced-apart main shaft holes 4211 and secondary shaft holes 4212 (e.g. Figure 9 As shown, the first power output shaft 412 of the drive device 410 is locked to the bracket 421 through the main shaft hole 4211, allowing the bracket 421 to rotate under the drive of the first power output shaft 412 with the main shaft hole 4211 as the axis. The stirring shovel 422 is connected to the bracket 421 at the position corresponding to the secondary shaft hole 4212 through the second power output shaft 431. The second power output shaft 431 may be an extension formed from the end of the stirring shovel 422 connected to the bracket 421 and is part of the stirring shovel 422; or it may be a component of the transmission device 430 and externally connected to the stirring shovel 422.

[0048] The stirring spatula 422 may include a stirring part 4222 and a connecting part that connects the stirring part 4222 to the cover 220. When the cover 220 is closed on the pot body 310, the stirring part 4222 faces the bottom surface and inner wall surface 314 of the pot body 310. Specifically, the connecting part may be a rod 4221 and a stirring part 4222. One end of the rod 4221 is connected to the support 421, and the stirring part 4222 is connected to the end of the rod 4221 away from the support 421. The stirring part extends outward in the radial direction on both sides of the rod 4221, and the extension distance on one side can at least cover the main shaft hole 4211 in the projection direction, for example, extending to the connection between the auxiliary spatula 423 and the support 421, so that when the stirring spatula 422 rotates in the pot body 310, it can take care of both the central area and the outer area of ​​the pot body 310. Furthermore, the stirring part 4222 can be, but is not limited to, a sheet-like structure bent in opposite directions on both sides of the rod 4221, and is coated with an elastomer, such as resin, rubber, or a combination thereof, so that the stirring part can bend and deform when it comes into contact with a hard material, and partially abut against the hard material. Therefore, in this embodiment, when the cover 220 is closed on the pot body 310, the stirring part 4222 can be press-fitted with the bottom surface 313 and the inner wall surface 314 in the inner cavity of the pot body 310, so that when part of the stirring part 4222 comes into contact with the bottom surface 313 and the inner wall surface 314 in the pot body 310, it is squeezed and bent and deformed, and abuts against the bottom surface 313 and the inner wall surface 314.

[0049] During the process of the spatula 420 moving from the first predetermined position to the second predetermined position, the interference fit between the second actuator 4232 and the side of the pot body 310 increases. During the process of the spatula 420 moving from the first predetermined position to the second predetermined position, the interference fit between the stirring part 4222 and the bottom surface of the pot body 310 increases.

[0050] An auxiliary shovel 423 is connected to one side of the bracket 421 where the main shaft hole 4211 is provided, so that the auxiliary shovel 423 and the stirring shovel 422 are located on opposite sides of the main shaft hole 4211, respectively. The auxiliary shovel 423 includes a first actuating part 4231 and a second actuating part 4232. When the cover 220 is closed on the pot body 310, the first actuating part 4231 faces the inner surface of the cover 220, and the second actuating part 4231 faces the inner wall surface 314 of the pot body 310. The first actuating part 4231 extends radially from the rotation axis of the auxiliary shovel 423 to the edge of the cover 220. The first actuating part 4231 and the second actuating part 4232 can be integrally formed or separately formed, and the two can be L-shaped. The first actuator 4231 extends outward along the radial direction of the bracket 421. The second actuator 4232 is connected to the outwardly extending end of the first actuator 4231, that is, to the end of the first actuator 4231 away from the bracket 421. It extends along the axial direction of the main shaft hole 4211 on the side of the bracket 421 where the stirring spatula 422 is located, so that the horizontal positions of the second actuator 4232 and the stirring spatula 422 are on the same side of the bracket 421. Therefore, when the cover 220 is closed onto the pot body 310, the auxiliary spatula 423 faces the inner surface 221 of the cover 220 with the first actuator 4231 facing it, and faces the inner wall surface 314 of the pot body 310 with the second actuator 4232 facing it. Similarly, the first actuator 4231 and the second actuator 4232 are respectively covered with an elastomer, so that the first actuator 4231 and the second actuator 4232 are respectively arranged on the auxiliary spatula 423 in the form of a scraper or scraper, so that they can contact the inner surface 221 of the cover 220 and the inner wall surface 314 of the pot body 310 respectively in an interference fit.

[0051] As the spatula 420 descends from the first predetermined position to the second predetermined position, the interference fit between the spatula 420 and the inner wall surface 314 and the bottom surface of the pot body 310 increases. That is, the contact pressure between the spatula 420 and the inner wall surface 314 and the bottom surface of the pot body 310 increases. It can be understood that the greater the contact pressure between the spatula 420 and the inner wall of the pot body 310, the better the scraping effect on the inner wall of the pot body 310 when the spatula 420 rotates. When water or cleaning solution is injected into the pot body 310 for cleaning, the greater the contact pressure between the spatula 420 and the inner wall of the pot body 310, the better the cleaning effect. Therefore, by controlling the contact pressure between the spatula 420 and the pot body 310 through the lifting device 440, the cooking equipment can operate in different cleaning modes or different cooking modes.

[0052] In some specific embodiments, when the spatula 420 is in the first predetermined position, the first actuator 4231 is in interference contact with the inner surface of the cover 220, and the interference amount can be controlled within [0.05mm, 5mm]. Preferably, the interference amount is controlled within [0.1mm, 3.5mm].

[0053] When the spatula 420 is in the first predetermined position, the second actuator 4232 is in contact with the inner wall surface 314 of the pot body 310. The actual position can be separated, in contact, or with interference. The gap between the second actuator 4232 and the side of the pot body 310 is maintained in [-2mm, 2mm]. Preferably, the gap is maintained in [-1mm, 2mm].

[0054] When the spatula 420 is in the first predetermined position, the stirring part 4222 is in contact with the bottom surface of the pot body 310. The actual position can be separated, in contact, or with interference. The gap between the stirring part 4222 and the bottom surface of the pot body 310 is maintained between [-1.5mm, 1.5mm]. Preferably, the gap is maintained between [-0.8mm, 0.8mm].

[0055] When the spatula 420 is in the second predetermined position, the first actuator 4231 is completely disengaged from the inner surface of the cover 220, and the gap is controlled within [0.5mm, 6mm], preferably within [1mm, 3mm]. When the spatula 420 is in the second predetermined position, the second actuator 4232 is in contact with the inner wall surface 314 of the pot body 310. The actual position can be in contact or interference, and the gap is controlled in [-2mm, 0mm]. Preferably, this value is controlled in [-1mm, 0mm].

[0056] When the spatula 420 is in the second predetermined position, the stirring part 4222 maintains an interference fit with the bottom surface of the pot body 310, and the interference amount is controlled within [0.5mm, 6mm], preferably within [0.5mm, 3mm]. It is worth noting that in this embodiment, the sum of the length of the second execution part 4232 of the auxiliary spatula 423 extending along the axial direction and the height of the stirring part 4222 on the bottom surface 313 of the pot body 310 exactly matches the height of the inner wall surface 314 of the pot body 310 along the axial direction. Therefore, when the spatula 420 rotates within the pot body 310 under the drive of the first power output shaft 412, the contact area between the second execution part 4232 and the stirring part 4222 can surround the entire inner wall surface 314. In this embodiment, the sum of the extension length of the second execution part 4232 and the height of the stirring part 4222 is greater than the height of the inner wall surface 314, causing the second execution part 4232 to partially overlap with the stirring part 4222 in the axial direction. In some embodiments of this application, the sum of the extension length of the second actuator 4232 and the height of the stirring part 4222 is exactly equal to the height of the inner wall surface 314. Alternatively, in other embodiments of this application, the second actuator 4232 and the stirring part 4222 may be spaced apart in the axial direction, and then the lifting device 440 may move them up and down to achieve full contact with the inner wall surface 314.

[0057] Meanwhile, the connection between the second execution part 4232 and the first execution part 4231 can also be transitioned with an arc angle, so that its structural shape can be consistent with or adapted to the arc angle of the bending area 250 of the lid 220. In this way, when the spatula 420 rotates inside the pot body 310, the stirring part 4222 of the stirring spatula 422 can cover the bottom surface 313 of the pot body 310, the second execution part 4232 and the stirring part 4222 can cover the inner wall surface 314 of the pot body 310, and the first execution part 4231 and the second execution part 4232 can cover the inner surface 221 of the lid 20, thereby fully covering all surfaces inside the pot body 310. In addition to better stirring of ingredients during cooking, it can also achieve a comprehensive cleaning effect in the subsequent cleaning process. In this embodiment, the spatula assembly 40 is located inside the pot body 310 and can rotate under the drive of the driving device 30 to stir the ingredients inside the pot body 310. The drive unit 30 and the spatula assembly 40 are connected via a first power output shaft 412 to drive the spatula assembly 40 around a rotation axis (i.e. Figure 10 The axis of revolution in the middle rotates.

[0058] To avoid high temperatures affecting service life and oil splattering soiling the drive device 30, in this embodiment of the application, the drive device 30 can be installed on the outside of the pot lid 20, and a clearance hole is provided on the pot lid 20 for the output shaft of the drive device 30 to pass through and connect to the spatula assembly 40.

[0059] Please refer to the reference. Figure 4 and Figure 10 In this embodiment, the spatula assembly 40 includes an auxiliary spatula 423, which has a scraping arm 4233 and an extension arm 4234. The scraping arm 4233 is close to the inner wall of the pot body 310 and contacts the inner wall of the pot lid 20. In this embodiment, the auxiliary spatula 423 may be generally elongated, such as a long rod or a long plate. The scraping arm 4233 contacts the inner wall of the pot lid 20. When the driving device 30 drives the auxiliary spatula 423 to rotate, the scraping arm 4233 rotates to scrape away food residue and oil stains on the inner wall of the pot lid 20, thereby cleaning the pot lid 20.

[0060] To better stir and stir-fry the ingredients, in some embodiments, the auxiliary spatula 423 also has a cleaning function. Specifically, the scraping arm 4233 has a connected horizontal scraping edge 4233a and a vertical scraping edge 4233b. The horizontal scraping edge 4233a contacts the inner wall of the pot lid 20 to scrape away food residue and oil stains from the inner wall of the pot lid 20 to clean the pot lid. The vertical scraping edge 4233b extends downward from the horizontal scraping edge 4233a, close to the inner wall of the pot body 310, to stir the ingredients in the pot.

[0061] In order to scrape off the food adhering to the inner wall of the pot 310 and stir it with the stirring spatula 422, or similarly scrape off the food on the inner wall of the pot 310 to achieve the purpose of cleaning, in one embodiment, the vertical scraping edge 4233b contacts the inner wall of the pot 310.

[0062] To better fit the shape of the cookware and achieve a better scraping effect, in one embodiment, the top surface of the horizontal scraping edge 4233a is contoured to the inner wall of the lid 20. This contouring means that the shape of the top surface of the horizontal scraping edge 4233a matches the shape of the inner wall of the lid 20, and the entire top surface of the horizontal scraping edge 4233a is completely in contact with the inner wall of the lid 20. This allows the horizontal scraping edge 4233a to scrape the entire inner wall of the lid 20 during the rotation of the auxiliary spatula 423. Similarly, the side surface of the vertical scraping edge 4233b is also contoured to the inner wall of the pot body 310, meaning the shape of the side surface of the vertical scraping edge 4233b matches the shape of the inner wall of the pot body 310.

[0063] In addition, the horizontal scraping edge 4233a and the vertical scraping edge 4233b are smoothly connected by an arc-shaped edge so that they can contact the connection between the pot body 310 and the lid 20 to scrape the food at the connection between the pot body 310 and the lid 20.

[0064] To prevent scratching the pot body 310 and the lid 20, in one embodiment, a second elastic body 4236 is provided on the scraping arm 4233. The scraping arm 4233 contacts the inner wall of the pot body 310 and the lid 20 through the second elastic body 4236. Optionally, the second elastic body 4236 can be integrally injection molded with the main body of the scraping arm 4233. Preferably, the second elastic body 4236 is made of soft rubber; the main body of the scraping arm 4233 is made of hard rubber to ensure strength. The integral injection molding method reduces installation and also prevents the two connected parts from detaching.

[0065] Please refer to the reference. Figure 10 and Figure 11 Furthermore, in this embodiment of the application, the auxiliary spatula 423 also has an extension arm 4234. The scraping arm 4233 and the extension arm 4234 are respectively disposed on both sides of the rotation axis. The extension arm 4234 is provided with a protruding structure 4235, which abuts against the inner wall of the pot lid 20.

[0066] In this embodiment, when the spatula assembly 40 is in the state of cleaning the pot lid 20, the scraping arm 4233 of the auxiliary spatula 423 contacts the inner wall of the pot lid 20 to clean it. Another protruding structure 4235 extends from the extension arm 4234 in the direction close to the pot lid 20. Simultaneously, this protruding structure 4235 also contacts the inner wall of the pot lid 20. When the reaction force generated by the pot lid 20 pushes the scraping arm 4233 downwards, the extension arm 4234 on the other side of the rotation axis tends to tilt upwards, ensuring that the protruding structure 4235 always abuts against the inner wall of the pot lid 20, thereby balancing the force exerted by the pot lid 20 on the scraping arm 4233. Through this design, when the spatula assembly 40 is in the state of cleaning the pot lid 20, the forces at both ends remain balanced, and the protruding structure 4235 of the auxiliary spatula 423 of the spatula assembly 40 is always in contact with the inner wall of the pot lid 20, thus achieving a better cleaning effect on the pot lid 20. The spatula assembly 40 makes full use of the balance of the auxiliary spatula 423 to achieve complete and reliable contact between the auxiliary spatula 423 and the inner wall of the pot lid 20. In terms of structural design, it fundamentally avoids the problem of unilateral tilting caused by processing errors and installation errors.

[0067] Meanwhile, the balancing protrusion 4235 and the scraping arm 4233 are distributed on both sides of the rotation axis. The balancing protrusion 4235 also takes into account the cleaning of the pot lid 20. The extension arm 4234 can be set shorter and closer to the rotation axis to clean areas that the scraping arm 4233 cannot reach, thus compensating for each other. In this way, through the left-right balance design, the problem that the scraping arm 4233 cannot fully and reliably contact the pot lid 20 due to unilateral tilting is solved, while also enhancing the cleaning ability of the auxiliary spatula 423 to clean hard-to-reach areas.

[0068] In some embodiments, the extension arm 4234 has a predetermined length in the horizontal direction, which is less than or equal to the length of the transverse scraping edge 4233a of the scraping arm 4233. The horizontal distance between the protrusion structure 4235 and the axis of rotation is less than or equal to the horizontal distance between the transverse scraping edge 4233a of the scraping arm 4233 and the axis of rotation. In other embodiments, the extension arm 4234 includes a horizontal extension and a vertical extension (not shown). The horizontal extension is provided with a protrusion structure 4235, which contacts the inner wall of the pot lid 20. The vertical extension abuts against the inner sidewall of the pot body 310. The extension arm 4234 and the scraping arm 4233 have the same structure and are symmetrical about the axis of rotation.

[0069] In some embodiments, the protruding structure 4235 and the second elastic body 4236 are distributed on both sides of the rotation axis and respectively abut against the inner wall of the pot lid 20. During the rotation of the spatula assembly 40, the protruding structure 4235 forms a first circular motion trajectory on the inner wall of the pot lid 20, and the second elastic body 4236 forms a second circular motion trajectory on the inner wall of the pot lid 20. The first motion trajectory and the second motion trajectory at least partially overlap in projection on the plane.

[0070] In some embodiments, the protrusion 4235 is elongated, with its length direction along the width direction of the extension arm 4234, extending to two opposite sides of the extension arm 4234 in the width direction. In other embodiments, the length direction of the protrusion 4235 is along the length direction of the extension arm 4234, thus, when the extension arm 4234 rotates around the rotation axis, the effective radius of the protrusion 4235 is larger, and the area that can be scraped against the inner wall of the pot lid is larger. Of course, in other embodiments, the protrusion 4235 may also be dot-shaped, such as cylindrical or hemispherical.

[0071] Multiple protrusions 4235 can be provided on the extension arm 4234. The multiple protrusions 4235 are arranged in a matrix, a ring or a linear arrangement. Taking the linear arrangement as an example, the multiple protrusions 4235 can be distributed in a straight line at intervals along the length of the extension arm 4234.

[0072] The scraping arm 4233 and the extension arm 4234 are respectively located on both sides of the rotation axis, including the following cases: the scraping arm 4233 and the extension arm 4234 extend in opposite directions, that is, the included angle between them is 180°. Alternatively, the scraping arm 4233 and the extension arm 4234 are respectively located on both sides of the rotation axis, including the following cases: the scraping arm 4233 and the extension arm 4234 extend in generally opposite directions, and the included angle between them is close to 180°, for example, but not limited to 160°, as long as they can maintain force balance. To achieve force balance and prevent the scraping arm 4233 from tilting downwards, the included angle between the scraping arm 4233 and the extension arm 4234 is set to be greater than 90°. In other embodiments, the spatula assembly 40 includes at least one scraping arm 4233 and / or at least one extension arm 4234. For example, the spatula assembly 40 includes one scraping arm 4233 and one extension arm 4234, which form a straight line. Alternatively, the spatula assembly 40 includes two scraping arms 4233 and two extension arms 4234, which form a cross-shaped auxiliary spatula 423. Furthermore, the spatula assembly 40 may also include more scraping arms 4233 and extension arms 4234, which are arranged radially around the axis of rotation. Optionally, multiple scraping arms 4233 and extension arms 4234 are evenly distributed in the circumferential direction of the rotation axis, and the scraping arms 4233 and extension arms 4234 are alternately arranged, forming an auxiliary shovel 423 with a symmetrical shape, so that the auxiliary shovel 423 can rotate more smoothly around the rotation axis.

[0073] The shape of the extension arm 4234 includes, but is not limited to, block, plate, rod, and cylindrical. In addition, the length and width of the extension arm 4234 can be the same, or the length of the extension arm 4234 can be much greater than the width, forming a long strip.

[0074] To avoid wear on the lid 20, in one embodiment, at least a portion of the protruding structure 4235 is configured as a first elastic body 4235b, and the protruding structure 4235 abuts against the inner wall of the lid 20 via the first elastic body 4235b. In this embodiment, the first elastic body 4235b includes, but is not limited to, silicone, rubber, or silicone rubber. At least, the portion of the protruding structure 4235 that contacts the inner wall of the lid 20 is the first elastic body 4235b.

[0075] In one embodiment, part of the protrusion structure 4235 is a rigid structure, and the other part is a first elastic body 4235b. Specifically, the protrusion structure 4235 includes a connecting protrusion 4235a and a first elastic body 4235b. The connecting protrusion 4235a is connected to the extension arm 4234, and the first elastic body 4235b wraps around the connecting protrusion 4235a. The connecting protrusion 4235a is made of a rigid structure, such as hard plastic, to ensure strength. The first elastic body 4235b is made of soft plastic. The first elastic body 4235b completely wraps around the outer surface of the connecting protrusion 4235a, completely preventing the rigid connecting protrusion 4235a from directly contacting the pot lid 20, thereby preventing wear on the pot lid 20.

[0076] To facilitate the installation of the first elastic body 4235b, in one embodiment, the extension arm 4234 is provided with a mounting groove (not shown in the figure), which surrounds the connecting protrusion 4235a, and the edge of the first elastic body 4235b is fitted into the mounting groove. The mounting groove can position and limit the first elastic body 4235b, reducing the possibility of movement of the first elastic body 4235b. At the same time, after the edge of the first elastic body 4235b is embedded in the mounting groove, the edge of the first elastic body 4235b is fixed, and the contact area between the first elastic body 4235b and the extension arm 4234 is large, resulting in a good fixing effect. Furthermore, the first elastic body 4235b and the extension arm 4234 can also be integrally formed. In some other embodiments, the first elastic body 4235b completely covers the outer surface of the extension arm 4234 and the connecting protrusion 4235a. The overall encapsulated structure reduces gaps and helps improve the cleaning effect of the spatula assembly 40.

[0077] Optionally, the connecting protrusion 4235a and the extension arm 4234 are integrally formed. For example, both the connecting protrusion 4235a and the extension arm 4234 are injection molded from hard plastic. Of course, in other embodiments, both the connecting protrusion 4235a and the extension arm 4234 can be made of stainless steel.

[0078] In another embodiment, the entire protrusion structure 4235 is a first elastic body 4235b. This entire protrusion structure 4235 can be integrally injection molded with the extension arm 4234. To ensure strength and prevent the extension arm 4234 from being deformed by compression, in one embodiment, the extension arm 4234 is made of hard plastic injection molded.

[0079] In one embodiment, the extension arm 4234 is shorter to reduce material usage. Meanwhile, a protruding structure 4235 is provided on the shorter extension arm 4234, near the center of the lid 20, to clean food residue at that central location, removing food residue from areas difficult to reach by the scraper arm 4233. Of course, in other embodiments, the length of the extension arm 4234 can be the same as that of the scraper arm 4233.

[0080] Furthermore, the cooking device also includes a stirring spatula 422 mounted on the extension arm 4234, located below the extension arm 4234. The stirring spatula 422 is situated at the bottom of the pot body 310 and is used to stir-fry the food within the pot body 310. The stirring spatula 422 can be elongated, cross-shaped, or similar shapes.

[0081] The stirring shovel 422 has two motion states. In the first motion state, the stirring shovel 422 rotates together with the auxiliary shovel 423, that is, the auxiliary shovel 423 rotates around the axis of rotation ( Figure 2 When the central axis of rotation rotates, it drives the stirring spatula 422 to rotate together. In the second motion state, the stirring spatula 422 also rotates relative to the auxiliary spatula 423 around its own axis of rotation. The axis of rotation and the axis of revolution are parallel and both in the vertical direction. Through its rotation and revolution, the stirring spatula 422 has different radii of rotation and different stirring ranges, which can better stir the food at the bottom of the pot 310. The rotation and revolution can occur simultaneously, or only one of the rotations can occur, such as the rotation and revolution occurring alternately.

[0082] In this embodiment, the protruding structure 4235 is positioned between the rotation axis and the revolution axis. Specifically, the auxiliary shovel 423 has a rotation hole 4237, and the stirring shovel 422 has a second power output shaft 431 that engages with the rotation hole 4237. The second power output shaft 431 can rotate relative to the rotation hole 4237, allowing the stirring shovel 422 to rotate. Along the rotation axis, the protruding structure 4235 may partially overlap with the rotation hole 4237.

[0083] This application also proposes a spatula assembly 40. For the specific structure of the spatula assembly 40, please refer to the above embodiments, which will not be repeated here.

[0084] It should be noted that the first execution unit 4231 in the above embodiment includes an extension arm 4234 and a horizontal scraping edge 4233a, and the second execution unit 4232 is a vertical scraping edge 4233b.

[0085] To improve the cleaning effect of the spatula 420 on the pot body 310 and the lid 220, an elastomer can be coated on the spatula 420. This elastomer can be a first actuator 4231 including a first elastic portion for scraping against the inner surface of the lid 220; and / or a second actuator 4232 including a second elastic portion for scraping against the inner wall surface 314 of the pot body 310; and / or a stirring part 4222 including a third elastomer for scraping against the inner wall surface 314 and the bottom surface of the pot body 310. The first and second elastic portions can be integrally formed to constitute the aforementioned second elastomer 4236.

[0086] like Figure 10 and Figure 12 As shown, the first actuating part 4231 includes a first rigid body, and a first elastic part covers the outer surface of the first rigid body; the second actuating part 4232 includes a second rigid body, and a second elastic part covers the outer surface of the second rigid body. For example, the first rigid body and the second rigid body can be integrally molded, or the first rigid body and the second rigid body can be integrally die-cast to ensure reliable strength and hardness, and improve the service life of the auxiliary shovel 423. The first elastic part and the second elastic part can also be integrally injection molded onto the first rigid body and the second rigid body. It should be noted that the cross-sectional shapes of the first actuating part 4231 and the second actuating part 4232 can be the same. Furthermore, the cross-sectional shapes of all parts of the first actuating part 4231 and the second actuating part 4232 can be the same.

[0087] A first elastic contact portion J1 is formed at the position on the first elastic portion for contacting the inner surface of the cover 220. In the cross-section of the first actuating portion 4231, the distance H1 from the first elastic contact portion J1 to the first rigid body is greater than the distances (W2, W3) from other positions on the first elastic portion to the first rigid body. Therefore, when cleaning the cover 220, the presence of the first rigid body ensures that the entire first actuating portion 4231 is not easily deformed as a whole, while the presence of the first elastic portion allows the first actuating portion 4231 to fit well against the cover 220, ensuring a good cleaning effect. Furthermore, the greater distance H1 from the first elastic contact portion J1 to the first rigid body (W2, W3) provides better deformation space on the side of the first actuating portion 4231 that contacts the cover 220, further improving the cleaning effect.

[0088] The width W1 of the first elastic contact portion J1 should be appropriate. Its width W1 should not be too large, so that the coefficient of friction between the auxiliary shovel 423 and the inner wall 314 of the lid 220 and the pot body 310 is not too high, thus minimizing resistance and ensuring smooth rotation. The width W1 of the first elastic contact portion J1 should also not be too small, to improve the wear resistance of the auxiliary shovel 423. Therefore, the width W1 of the first elastic contact portion J1 can range from [0.1mm, 2mm], preferably within the range of [0.1mm, 1mm].

[0089] In some embodiments, the distance H1 from the first elastic contact portion J1 to the first rigid body can be in the range of [2mm, 20mm], and preferably, the range of H1 is controlled in the range of [2mm, 18mm].

[0090] In some embodiments, the distance W2 from the side of the first elastic portion to the first rigid body ranges from [0.5mm, 5mm], and preferably, the range of W2 is controlled within [0.5mm, 3mm].

[0091] In some embodiments, the width W3 at the widest point of the first elastic portion ranges from [3mm to 15mm], and preferably, the range of W3 is controlled within [5mm to 12mm].

[0092] A second elastic contact portion is formed at the position on the second elastic portion for contacting the inner wall surface 314 of the pot. In the cross-section of the second actuating portion 4232, the distance from the second elastic contact portion to the second rigid body is greater than the distance from other positions on the second elastic portion to the second rigid body. In this embodiment, the cross-sectional structure of the second elastic portion and the second rigid body can be the same as the cross-sectional structure of the first elastic portion and the first rigid body, and both can be referred to the appendix. Figure 12 The cross-sectional view of the structure is shown. Therefore, the structure of the second elastic part and the second rigid body will not be described in detail here.

[0093] Figure 13 This is a cross-sectional view of the stirring spatula provided in an embodiment of this application. Similarly, the stirring part 4222 includes a third rigid body 4222a, and a third elastic body 4222b covers the outer surface of the third rigid body 4222a. A third elastic contact part J3 is formed on the stirring part 4222 at a position for contacting the bottom surface of the pot body 310. In the cross-section of the stirring part 4222, the distance H2 from the third elastic contact part J3 to the third rigid body is greater than the distance from other positions on the third elastic body to the third rigid body. As a result, the side of the stirring part 4222 that contacts the pot body 310 has better deformation space, further improving the cleaning effect.

[0094] Specifically, the width W4 of the widest part of the third elastic body 4222b of the stirring part 4222 is in the range of [3mm, 15mm], preferably, the range of W4 is controlled in the range of [3mm, 10mm]; in some embodiments, the distance H2 from the third elastic body 4222b of the stirring part 4222 to the third rigid body is in the range of [3mm, 25mm], preferably, the range of H2 is controlled in the range of [3mm, 20mm].

[0095] Please refer to Figure 4 , Figure 5 , Figures 7 to 9 The mixing shovel 422 and the auxiliary shovel 423 can be driven by meshing planetary gear set; the planetary gear set 432 includes a sun gear and planet gears, the sun gear is connected to the auxiliary shovel, and the planet gears are connected to the mixing shovel 422. When the sun gear receives rotational power, the auxiliary shovel 423 rotates, and the mixing shovel 422 revolves around the rotation axis of the auxiliary shovel 423 while rotating on its own axis.

[0096] Specifically, the transmission device 430 of the spatula assembly 40 is mounted on the support 421 of the spatula 420. The transmission device 430 includes a planetary gear set 432 and a second power output shaft 431 (in embodiments where the stirring spatula 422 has its own power output shaft, the transmission device 430 may not include the second power output shaft 431). The planetary gear set 432 includes a sun gear 4321 and planet gears 4322, which are respectively mounted on the support 421 at positions corresponding to the main shaft hole 4211 and the secondary shaft hole 4212, and the gears of the sun gear 4321 and planet gears 4322 mesh with each other, so that one can drive the other to rotate. The first power output shaft 412 passes through the sun gear 4321 and engages with the main shaft hole 4211, and the axis of the first power output shaft 412 can serve as the revolution axis; the second power output shaft 431 passes through the planet gears 4322 and engages with the secondary shaft hole 4212, and the axis of the second power output shaft 431 can serve as the rotation axis. Therefore, driven by the rotating motor 411, the bracket 421 is rotated through the first power output shaft 412; at this time, the sun gear 4321 rotates with the first power output shaft 412, causing the planet gear 4322 to rotate in the opposite direction, which in turn drives the second power output shaft 431 to rotate, so that the stirring shovel 422 and the auxiliary shovel 423 revolve with the bracket 421, and the stirring shovel 422 rotates on its own axis on the bracket 421.

[0097] Therefore, when the spatula 420 rotates along the circumference of the pot body 310, the stirring spatula 422 can not only perform static stirring by revolving around the support 421 within the pot body 310, but also perform dynamic stirring by rotating on its own axis. This prevents the ingredients from becoming excessively concentrated in the central area of ​​the pot body 310 or scattered to the outer area during stirring, thus providing a more uniform stirring effect. Furthermore, due to the characteristic of the auxiliary spatula 423 revolving around the support 421, it can scrape off the ingredients that splash and adhere to the inner wall during stirring, allowing them to fall back into the stirring area of ​​the stirring spatula 422, thus avoiding waste of some ingredients or uneven cooking.

[0098] Please refer to Figure 4 The lifting device 440 is connected to the drive device 410 to drive the spatula 420 to rise or fall within the pot body 310 along the axial direction of the first power output shaft 412 (i.e., the axial direction of the main shaft hole 4211). The lifting device 440 may include a cam lifting mechanism, a screw lifting mechanism, or a rack and pinion lifting mechanism, etc. In this embodiment, a cam lifting mechanism including a cam 441, a cam motor 442, and a reset element 443 is used as an example for illustration, but it is not limited thereto.

[0099] Cam 441 is disposed at the top of connector (first power output shaft 412) within body 212 of cantilever 210, and has a near repose point 4411 and a far repose point 4412 on its circumference. Cam motor 442 is electrically connected to cam 441 to drive cam 441 to rotate, so that the near repose point 4411 and the far repose point 4412 can alternately contact connector (first power output shaft 412), providing displacement stroke of first power output shaft 412 in the axial direction. Reset element 443 is disposed between bracket 421 and connector, and the deformation direction of reset element 443 is consistent with the movement direction of connector; when the far repose point of cam 441 abuts against connector, reset element 443 is in a deformed state; as cam 441 rotates from far repose point to near repose point and abuts against connector, the deformation of reset element 443 gradually decreases.

[0100] Specifically, the reset element 443 can be sleeved on the first power output shaft 412. It can be, but is not limited to, a preload spring or a tension spring, so that the first power output shaft 412 is pulled by the reset element 443, normally maintaining itself in a first predetermined position, and can be displaced to a second predetermined position under the push of the cam 441. In this embodiment, the first predetermined position is the position where the spatula 420 approaches the lid 20 and contacts or abuts against the inner surface 221 of the lid 220, and the second predetermined position is the position where the spatula 420 approaches the bottom surface 313 of the pot body 310 and contacts or abuts against the bottom surface 313 of the pot body 310. In some embodiments of this application, the first and second predetermined positions may be opposite to those in this embodiment, and therefore are not limited to the examples described in this embodiment.

[0101] With the configuration of the lifting device 440 described above, when the cam 441 is driven by the cam motor 442, it contacts the first power output shaft 412 at its far rest point 4412, causing the first power output shaft 412 to be compressed and driving the spatula 420 to descend to the second predetermined position, and applying force to the reset element 443. Therefore, when the cam motor 442 drives the cam 441 to rotate and contacts the first power output shaft 412 at its near rest point 4411, the elastic restoring force of the reset element 443 drives the first power output shaft 412 to move towards the first predetermined position, thereby causing the spatula 420 to rise and return to the first predetermined position.

[0102] In this way, in the cooking device 1 provided in this application embodiment, in addition to providing a two-dimensional stirring and cleaning mode through the stirring spatula 422 and auxiliary spatula 423 of the spatula 420, the stirring spatula 422 and auxiliary spatula 423 can also rise or fall along the axial direction in the pot body 310 through the configuration of the lifting device 440, thereby providing a multi-dimensional operation mode of 360-degree circular motion, realizing 360-degree stirring and cleaning of the inside of the pot body 310 without dead angles.

[0103] In one application scenario, after the user completes the cooking program using the cooking device 1, they can select a cleaning mode on the display control panel 120 to clean the inner cavity of the pot body 310. When the lid 220 of the pot lid 20 is closed onto the pot body 310, the second actuating part 4232 of the auxiliary spatula 423 contacts the inner wall surface 314 of the pot body 310, and the stirring part 4222 of the stirring spatula 422 simultaneously contacts the bottom surface 313 of the pot body 310 and the inner wall surface 314 near the bottom surface 313. At this time, water is added to the pot body 310, and the rotating motor 411 is started, causing the first power output shaft 412 to drive the stirring spatula 422 and the auxiliary spatula 423 of the spatula 420 to revolve within the pot body 310, cleaning the bottom surface 313 and the inner wall surface 314 of the pot body 310 in a circumferential direction. Simultaneously, under the operation of the planetary gear set 432, the stirring spatula 422, driven by the second power output shaft 431, rotates within the pot body 310, thereby performing circumferential rotational cleaning of the inner wall surface 314 and bottom surface 313 of the pot body 310. Furthermore, through the interference fit between the stirring spatula 422 and the auxiliary spatula 423 and the bottom surface 313 and inner wall surface 314 of the pot body 310 respectively, adhering substances can be scraped off from the bottom surface 313 and inner wall surface 314, providing a better cleaning effect.

[0104] While the spatula 420 is rotating and cleaning, a lifting device 440 can be used to move the spatula 420 up and down within the pot body 310. When the cam 441 is driven by the cam motor 442 to move to the near rest point 4411, the first power output shaft 412, under the elastic restoring force of the reset element 443, drives the stirring spatula 422 to move upward. At this time, the first actuator 4231 of the auxiliary spatula 423 and the inner surface 221 of the lid 220 are in an interference fit, thereby scraping and cleaning the oil or moisture adhering to the lid 220. When the cam 441 moves to the far rest point 4412, the first power output shaft 412 pushes the reset element 443 and drives the spatula 420 to move downward. At this time, the stirring spatula 422 is in an interference fit with the bottom surface 313 of the pot body 310, thereby scraping and cleaning the bottom surface 313 of the pot body 310. When the spatula 420 moves downward, the pressure applied to the cover 220 by the first actuator 4231 of the auxiliary spatula 423 is released, which can reduce the rotational resistance of the stirring spatula 422 when performing the cleaning task and improve the cleaning efficiency.

[0105] like Figure 4 and Figure 7As shown, in some embodiments of this application, an elastic element 433, such as a spring or a sheet, can be selectively provided on the second power output shaft 431. In this embodiment, the elastic element 433 is sleeved on the second power output shaft 431 in the form of a pre-compressed spring, and the two opposite ends of the elastic element 433 abut against the support 421 and the rod 4221 of the spatula 420, respectively. Therefore, when the lifting device 440 drives the spatula 420 to descend to the second predetermined position in the pot body 310, so that the stirring part 422 contacts the bottom surface 313 of the pot body 310, the elastic element 433 will be simultaneously subjected to the downward pressure of the support 421, and its elastic restoring force will be applied to the rod 4221, thereby making the stirring part 422 press against the bottom surface 313 of the pot body 310. Similarly, when the lifting device 440 raises the spatula 420 to the first predetermined position within the pot body 310, the support 421 is subjected to the elastic restoring force of the reset element 443, causing the stirring part 422 to contact the bottom surface 313 of the pot body 310; simultaneously, the first actuating part 4231 of the auxiliary spatula 423 presses against the inner surface 221 of the lid 220. Therefore, for some ingredients that are prone to sticking to the pot during cooking, the above configuration allows the stirring spatula 422 and the auxiliary spatula 423 to provide a powerful scraping effect for cleaning the pot body 310 and the lid 20. In addition to ensuring the quality of the food and preventing burning during cooking, it also provides a powerful scrubbing effect during the cleaning process after cooking, ensuring a thorough cleaning. In some embodiments of this application, in order to reduce the scratching damage of the spatula 420 to the bottom surface 313 and the inner wall surface 314, when the spatula 420 is in a first predetermined position, a second predetermined position or a position between the two, the pressure of the stirring part 422 on the bottom surface 313 or the inner wall surface 314 of the pot body 310 is less than or equal to 10 Newtons (N).

[0106] In some embodiments, a cooking device is also provided, comprising: a cooking container including a pot body and a lid, the lid being fitted onto the pot body to form a cooking cavity; a spatula assembly located in the cooking cavity, the spatula assembly including a spatula and a lifting device; the lifting device being disposed on the lid and drivenly connected to the spatula, the lifting device being capable of driving the spatula to move up and down relative to the pot body between a first predetermined position and a second predetermined position; when the spatula is in the first predetermined position, the spatula is in contact with the inner surface of the lid; when the spatula is in the second predetermined position, the spatula is out of contact with the inner surface of the lid.

[0107] In some embodiments, a cooking device is also provided, including: a cooking container including a pot body and a lid, the lid being fitted onto the pot body to form a cooking cavity; a spatula assembly located in the cooking cavity, the spatula assembly including a spatula and a lifting device, the spatula including an auxiliary spatula capable of contacting the lid and a stirring spatula capable of contacting the bottom surface of the pot body; the lifting device being disposed on the lid and drivenly connected to the spatula, the lifting device being capable of driving the spatula to move up and down relative to the pot body.

[0108] In addition, based on the height-adjustable spatula 420, the cooking effect and user experience are further improved.

[0109] In some embodiments, a Hall element and a magnet can be installed on the stirring spatula 422. Specifically, a magnet can be installed on the stirring part 4222 and a Hall element can be installed on the rod 4221. Alternatively, a Hall element can be installed on the stirring part 4222 and a magnet can be installed on the rod 4221, so that the stirring part 4222 can position itself during rotation, thereby enabling the ingredients at a specific location to be longitudinally cut by controlling the lifting and lowering at a designated position.

[0110] Assuming that each detection by the Hall element represents one rotation of the stirring section 4222, the rotational speed of the stirring section 4222 can be calculated using the time interval between two detections. Then, based on the running time, the angle of rotation in the next rotation cycle can be calculated, thereby accurately locating the position of the stirring section 4222.

[0111] Furthermore, the rotation speed can be updated every time the stirring section 4222 rotates, thereby obtaining the real-time rotation speed and improving the positioning accuracy of the stirring section 4222.

[0112] In some embodiments, an infrared sensor camera can be installed on the lid 220, enabling the infrared sensor camera to obtain a real-time heat map of the food being heated in the pot. Based on this heat map, areas of uneven heating can be calculated. The stirring unit 4222 is controlled to rise and then descend in areas of uneven heating to selectively disperse the food, ensuring even heating. Furthermore, the stirring unit 4222 can be controlled to perform lifting, lowering, and rotating movements in areas of uneven heating, thereby scraping away the unevenly heated areas and precisely stirring the unevenly heated parts to ensure even heating.

[0113] Through creative work, the inventors also discovered that the texture of the cooked dish is related to the stirring speed and time of the stirring spatula. Therefore, embodiments of this application also dynamically adjust the stirring speed of the stirring spatula. Specifically, a pressure sensor can be installed at the stirring section 4222; or a device for detecting the motor current can be designed at the drive motor of the spatula assembly 40, where a larger drive motor current results in greater pressure on the stirring section 4222.

[0114] Based on the above, the rotation speed and lifting of the mixing shovel 422 are controlled, taking the design of a pressure sensor at the mixing part 4222 as an example.

[0115] When excessive pressure is detected on the stirring spatula 422, the speed of the stirring spatula 422 can be reduced first, then the stirring spatula 422 can be driven to rise, and then the speed of the stirring spatula 422 can be slowly increased. After a preset time (which may be a few seconds), the stirring spatula 422 can be lowered. At this time, the pressure on the stirring spatula 422 can be detected. If the pressure is within the normal range, normal stirring can continue. If the pressure is too high, the above actions can be repeated. If too many calibrations are performed, or the speed of the stirring spatula 422 is too low, an alarm signal can be issued (an alarm device can be set on the cooking equipment) to remind the user that the stirring spatula has stalled. When insufficient pressure is detected on the stirring spatula 422, the speed of the stirring spatula 422 can be increased, and then the stirring spatula 422 can be driven to fall. The pressure on the stirring spatula 422 can be detected again. If the pressure is within the normal range, normal stirring can continue. If insufficient pressure is detected, the above actions can be repeated. If too many calibrations are performed, or the speed of the stirring spatula 422 is too high, an alarm signal can be issued (an alarm device can be set on the cooking equipment) to remind the user that the pot is empty. This improves the safety and efficiency of cooking with this equipment.

[0116] As mentioned above, since different ingredients and cooking methods result in varying degrees of oil and food residue in the pot, cooking equipment with a self-cleaning mode also needs to provide multiple cleaning modes so that users can choose according to their needs, or select the corresponding cleaning mode based on the recipe selected by the user through the control module of the equipment itself, in order to achieve the purpose of cleaning and meet the user's needs.

[0117] The self-cleaning method and control method of the cooking equipment and / or smart IoT terminal device of this application are further described below through some method embodiments.

[0118] Please refer to Figure 14 In the use of the intelligent IoT terminal device provided in one embodiment of this application, after the user puts the lid on the pot, they can select a recipe through the display control panel on the base. At this time, the control module loads the corresponding cooking parameters according to the recipe selected by the user. For example, based on the mass and proportion of various main ingredients and seasonings, it adaptively loads parameters such as cooking time, spatula rotation method, revolution speed, stirring spatula rotation speed, estimated steam volume, water supply volume of the water supply module, and heating volume of the temperature control module. Then, the various devices and modules are activated to work together to cook the main ingredients.

[0119] After the main ingredients are cooked, the control module can send a signal to the user via the display panel to notify the user that the cooking is complete and that the dish is ready to be served. Next, after the user closes the lid back onto the pot, the control module determines that the cooking process is finished and activates the lifting device to move the spatula to a first predetermined position inside the pot, ensuring an interference fit between the spatula's stirring blade and the bottom surface of the pot (S100). Then, the control module activates the drive device, causing the spatula's stirring blade and auxiliary blade to revolve around the first power output shaft within the pot, thereby cleaning the inner wall and bottom surfaces of the pot along its circumference (S110). Simultaneously, since the transmission device can be linked to the drive device, the drive device activates the transmission device, causing the stirring blade to rotate around the second power output shaft within the pot, thereby cleaning the bottom surface of the pot along the spatula's axial direction (S120). During this process, the interference fit between the side of the stirring blade and the second actuating part of the auxiliary blade with the inner wall surface of the pot effectively removes any residue adhering to the inner wall. Meanwhile, the interference fit between the stirring part of the stirring spatula and the bottom surface of the pot allows for powerful removal of residue. Furthermore, a lifting device can be used to move the stirring part as close to the bottom of the pot as possible, pressing it firmly against the bottom surface under downward pressure to provide a more powerful rotating cleaning mode, removing even stubborn residue from the bottom.

[0120] After the predetermined number of cleaning cycles is completed, the control module stops the spatula from rotating and ends the self-cleaning program.

[0121] During the above process, the control module can also, based on the ease with which the main ingredients and seasonings adhere to the bottom and inner walls of the pot during cooking, activate the water-filling module to add water to the pot and the temperature control module to heat the added water, thereby generating steam within the pot to soften the residue adhering to the bottom and inner walls. This allows the spatula to more easily remove these residues, accelerating the cleaning process and improving efficiency. Furthermore, it is understood that in the self-cleaning method or control method of this application embodiment, the starting position of the cleaning procedure can be either a first cleaning position or a second cleaning position, and these two positions can be interchanged. It is not limited to the method described in the above embodiment, which starts from the first cleaning position and then moves to the second cleaning position.

[0122] Furthermore, after the self-cleaning process for the inner wall and bottom of the pot is complete, a corresponding cleaning process for the lid can be determined based on user needs or recipe selection. In the lid cleaning process, the spatula can simultaneously clean the bottom, inner wall, and inner surface of the pot, with a focus on the inner surface of the lid. Similarly, the lifting device is activated via the control module to move the spatula to a second predetermined position, ensuring an interference fit between the auxiliary spatula and the inner surface of the lid. At this point, the first actuator of the auxiliary spatula is in interference contact with the inner surface of the lid, while the second actuator and the side of the stirring spatula's stirring part simultaneously contact the inner wall of the pot. Therefore, when the control module activates the drive device to rotate the stirring spatula and auxiliary spatula, the inner wall of the pot and the inner surface of the lid can be cleaned simultaneously along the circumference of the pot. If the lifting device is used to press the first actuator against the inner surface of the lid, the cleaning intensity of the spatula on the lid can be further enhanced. During the above process, the drive device synchronously starts the transmission device, which drives the stirring spatula to rotate, so that the stirring spatula cleans the bottom surface of the pot along the axis of the spatula, thereby achieving a 360-degree all-round, no-dead-angle cleaning effect of the stirring spatula and auxiliary spatula on the area to be cleaned inside the pot.

[0123] Please refer to Figure 15 One embodiment of this application provides a control method for a cooking device, including: The control module determines the degree of contamination inside the pot and selects either a regular cleaning program or an enhanced cleaning program based on the degree of contamination (S200). Similar to the previous self-cleaning method, the control module can determine the degree of contamination inside the pot based on the content of the selected recipe. If the contamination is minor, a regular cleaning program is executed in subsequent steps; if it is heavily contaminated, an enhanced cleaning program is executed. Next, the control module activates the lifting device to move the spatula to the first cleaning position and makes the spatula and the bottom surface of the pot in interference contact (S210). In this step, the control module can detect the current position of the spatula in advance. If the current position of the spatula is already in the first cleaning position, this step can be omitted, or the lifting device can be used to move the stirring spatula along the rotation axis to press against the bottom surface of the pot. Then, the control module activates the spatula to stir and clean within the cleaning time range of the first value range (S220). Next, the spatula is moved to the second cleaning position and makes the spatula and the inner surface of the pot lid in interference contact (S230). After the spatula moves to the second cleaning position, the control module activates the spatula to stir and clean within the cleaning time range of the second value (S240). Finally, after the cleaning time within the second value range ends, the cleaning ends (S250).

[0124] For example, in a standard cleaning procedure, the control module drives a lifting device to lower the spatula to the lowest position inside the pot, such as the first cleaning position. Next, the pot is selectively heated at maximum power and water is added at minimum flow rate, with a timer T0 for the water addition process, where T0 is greater than 0 seconds and less than or equal to 200 seconds. Then, a wait of T1 seconds (e.g., greater than 0 seconds and less than or equal to 100 seconds) is initiated. The control module then activates the drive device, rotating the spatula and stirring for T2 seconds (e.g., greater than 0 seconds and less than or equal to 80 seconds). Water addition stops when the set value is reached in T0 seconds, and stirring stops at the end of T2 seconds. The control module then activates the lifting device to raise the spatula to the highest position, such as the second cleaning position. The control module then activates the drive device again, rotating the spatula and stirring for T3 seconds (e.g., greater than 0 seconds and less than or equal to 80 seconds). After T3 seconds, the control module activates the lifting device to lower the spatula to the lowest position and stops heating, thus ending the cleaning procedure.

[0125] Alternatively, in an enhanced cleaning process, the spatula is first moved to a predetermined position, for example, lowered to the lowest position within the pot. Next, the pot is selectively heated at maximum power and water is added at the minimum flow rate, with a timer set for the water addition duration T4, where T4 is greater than 0 seconds and less than or equal to 200 seconds. Then, a wait of T5 seconds (e.g., greater than 0 seconds and less than or equal to 100 seconds) is initiated. The control module then activates the drive mechanism, rotating and stirring the spatula for T6 seconds (e.g., greater than 0 seconds and less than or equal to 100 seconds). Water addition stops when the set value is reached in T4 seconds, and stirring stops at the end of T6 seconds. The control module then activates the lifting mechanism to raise the spatula to the highest position, for example, the second cleaning position. The control module then activates the drive mechanism again, rotating and stirring the spatula for T7 seconds (e.g., greater than 0 seconds and less than or equal to 100 seconds). After T7 seconds, the control module activates the lifting mechanism to lower the spatula to the lowest position and stops heating, thus ending the cleaning process.

[0126] After the cleaning cycle ends, the control module sends a signal to the display panel or emits a prompt sound to remind the user that the cleaning process is complete and the lid can be opened to pour out water. Furthermore, when the lid is closed again, the control module can send a confirmation signal to the user to indicate whether the cleaning needs to be repeated.

[0127] Furthermore, other embodiments of this application provide a biomimetic cleaning procedure that simulates the manual cleaning of the pot body and lid by a user. For example, in these embodiments, if the target cleaning area is the first cleaning position, the control module activates a lifting device to raise the spatula to the second cleaning position and reduces the spatula's rotation speed (if the spatula has already started rotating). Then, the lifting device moves the spatula towards the first cleaning position, while the drive device gradually increases the spatula's rotation speed so that when the spatula reaches the first cleaning position, it is at its highest rotation speed, and the inner surface of the lid makes interference contact with the inner wall of the upper half of the pot body. This step is similar to a user manually rotating and wiping the pot body, which can improve cleaning efficiency and cleanliness.

[0128] Similarly, if the target cleaning area is the second cleaning position, the control module activates the lifting device to lower the spatula to the first cleaning position. Then, it moves the spatula towards the second cleaning position, simultaneously increasing its rotation speed so that when the spatula reaches the second cleaning position, it is at its highest rotation speed, making interference contact between the bottom surface of the pot and the inner wall of the lower half of the pot. This method provides a better cleaning effect.

[0129] Please refer to Figure 16 Specifically, the self-cleaning method and control method provided in the embodiments of this application can be selected individually or in combination, depending on the circumstances.

[0130] First, the degree of contamination inside the pot is determined (S300). This determination can be made by the user or by the cooking equipment. In this embodiment, a control module is also provided in the base of the cooking equipment, which is at least electrically connected to the display operation panel, the drive device, and the lifting device. In some embodiments of this application, the control module is also electrically connected to the water filling module and the temperature control module, etc., to provide corresponding control programs between the various devices or modules. The control module can determine whether the degree of contamination inside the pot after the current cooking program is completed is general contamination or heavy contamination based on the recipe selected by the user on the display operation panel.

[0131] For example, cooking processes often involve adding ingredients such as oils (e.g., various vegetable oils, chili oil, animal oil, oyster sauce, etc.); sauces (e.g., tomato sauce, sesame paste, etc.); high-oil-content seasonings (e.g., cooking oils used as hot pot bases or other heavily oiled condiments); or ingredients that easily produce a paste-like consistency (e.g., thickeners, milk, etc.). Therefore, the proportion or quality of these ingredients in the chosen recipe can be used as a basis for judgment. For example, in this implementation, a dish is considered heavily contaminated if any of the following conditions are met: the recipe contains 10 grams or more of oil (e.g., 15, 20, or 25 grams); the recipe contains 10 grams or more of sauce (e.g., 15, 18, or 23 grams); the recipe contains 10 grams or more of heavily oily condiments such as hot pot base (e.g., 12, 15, or 25 grams); and the recipe contains 5 grams or more of ingredients that easily produce a paste, such as starch or milk (e.g., 6, 8, or 12 grams). Therefore, in subsequent steps, a regular cleaning procedure or an enhanced cleaning procedure (S310) can be selected based on the degree of contamination. When heavily contaminated, the enhanced procedure can be selected; conversely, if the ingredients in the recipe do not fall under the above conditions, it is considered moderately contaminated, and a corresponding regular cleaning procedure can be selected.

[0132] Next, the lid is closed. A command is sent to the lifting device via the control module, causing the cam motor to drive the cam to rotate, which in turn moves the first power output shaft to the first cleaning position inside the pot (S320). The first cleaning position can be either the spatula lowered to the lowest position inside the pot or raised to the highest position inside the pot. The lowest position is where the stirring part of the stirring spatula is in an interference fit with the bottom surface of the pot, and the highest position is where the first actuating part of the auxiliary spatula is in an interference fit with the inner surface of the lid. Therefore, in this embodiment, the cleaning sequence can be selected from bottom to top (pot to lid) or top to bottom (lid to pot) depending on different usage needs or habits.

[0133] After the spatula moves to the first cleaning position, water is added to the pot (S330). In the step of adding water by turning on the water pump, the amount of water added can be timed according to a preset water addition duration, or calculated based on the weight of the main ingredient and a pre-set base amount. In the embodiment of preset water addition duration, the water addition duration can be set to a range greater than 0 seconds and less than or equal to 200 seconds, or a range greater than 0 seconds and less than or equal to 190 seconds. For example, the range could be [10s, 150s] (greater than or equal to 10 seconds, less than or equal to 150 seconds) or [5s, 170s]. Alternatively, in the embodiment of calculating the amount of water added based on the weight of the main ingredient, the base amount of water can be added to one-tenth of the weight of the main ingredient in the pot. For example, in an embodiment where the base quantity is preset to 30ml, and the main ingredients include 150g of egg liquid and 350g of tomatoes, the calculation method for the amount of water added is 30ml + (150 + 350) / 10, therefore, the amount of water added is 80ml. The above method of adding water to the pot is only for illustrative purposes and is not limited to this.

[0134] In some embodiments of this application, the amount of water to be added can be set according to a preset electronic recipe in the cooking device. The electronic recipe includes a self-cleaning step, which includes parameters such as self-cleaning mode, water volume, and self-cleaning time. Users can pre-edit the water volume in the electronic recipe, for example, by selecting 200ml, 300ml, etc., to complete the self-cleaning process.

[0135] In some embodiments of this application, the water volume can be matched according to the self-cleaning mode. The self-cleaning modes of the cooking equipment include at least one of the following: light self-cleaning, medium self-cleaning, and heavy self-cleaning. Each self-cleaning mode is matched with a preset water volume, including: 200ml for light self-cleaning, 300ml for medium self-cleaning, and 300-400ml for heavy self-cleaning. When a user or electronic recipe selects a self-cleaning mode, the water volume for that cleaning mode is directly selected. Different water volumes are adapted to different cleaning modes, which can save water and improve the user experience without reducing the cleaning effect.

[0136] During or after the water addition process, the control module sends a command to the drive device, causing the rotary motor to drive the first power output shaft to rotate, thereby activating the spatula to stir and clean within a first value range of cleaning time (S340). The first value range can be, but is not limited to, greater than 0 seconds and less than or equal to 80 seconds, or greater than 0 seconds and less than or equal to 100 seconds, depending on the selected cleaning method. Furthermore, the activation method of the spatula can be selected within the range of the first power output shaft's rotational speed being greater than 0 revolutions per second and less than or equal to 200 revolutions per second, or greater than 0 revolutions per second and less than or equal to 190 revolutions per second. For example, driven by the first power output shaft, the stirring spatula and auxiliary spatula can revolve within the pot at a rotational speed of [20 r / s, 150 r / s] (greater than or equal to 20 revolutions per second, less than or equal to 150 revolutions per second) or [10 r / s, 180 r / s]. The rotational speed of the auxiliary spatula 423 can be in the range of 30~150 revolutions per minute, proportional to the operation of the planetary gear set. Furthermore, the rotation speed of the auxiliary spatula 423 is less than or equal to the rotation speed of the stirring spatula 422, which is more conducive to properly turning the food without making it messy. In addition, in conjunction with the revolution of the first power output shaft, the rotation speed of the stirring spatula in the pot can be a multiple of the revolution speed, and its value range is [0, 10] (0 to 10 times). For example, the stirring spatula can rotate at 5 times the revolution speed to strengthen the scrubbing of the main concentrated areas of the food in the pot.

[0137] After the cleaning time within the first value range ends, the spatula is moved to the second cleaning position inside the pot (S350). In this step, after the cleaning time within the first value range ends, the spatula can be moved to the second cleaning position while it continues to rotate; or it can be moved to the second cleaning position after stopping the rotation and stirring. The second cleaning position is different from the first cleaning position. For example, the first cleaning position is when the spatula is lowered to the lowest position inside the pot, and the second cleaning position is when it is raised to the highest position inside the pot, and vice versa.

[0138] Once the spatula is positioned in the second cleaning position, it is activated and stirs and cleans for the duration of the second cleaning time range (S360). Similar to the first time range, the second time range can also be, but is not limited to, greater than 0 seconds, less than or equal to 80 seconds, or greater than 0 seconds, less than or equal to 100 seconds, etc. After the cleaning time within the second time range ends, the cleaning process ends (S370). At this point, the self-cleaning program of the cooking equipment is complete.

[0139] In addition, in some embodiments of this application, the control module can also calculate the degree of contamination based on the proportion of ingredients to determine the number of times the above cleaning method is executed. This can be calculated using the following formula: 1 + (weight of ingredients / 30) = number of executions. For example, if the recipe contains 32g of peanut oil, the corresponding number of executions is 1 + (32 / 30), thus calculating two rounds of cleaning to ensure cleaning effectiveness.

[0140] Based on the above, since minimal human intervention is required during the cleaning process, and the multi-dimensional cleaning method involving the spatula's revolution, rotation, and lifting motion enables rapid and comprehensive self-cleaning of the lid, inner walls, and bottom of the pot. Furthermore, while ensuring effective cleaning, the pot can be washed quickly between two cooking sessions, preventing flavor transfer between dishes and minimizing cleaning time, thereby reducing cooking time between dishes and improving user efficiency.

[0141] The cleaning method of this application embodiment will be further described below through some application scenarios.

[0142] Please refer to Figure 17 In applications where a standard cleaning procedure is selected based on the degree of contamination, after the lid is closed, the spatula is lowered to its lowest position inside the pot (S400). Water is added to the pot for 190 or 200 seconds, and the pot is heated (S410). After this step, a predetermined time can be waited for to allow steam to be generated inside the pot, softening any residue; or the next step can be performed directly. Next, the spatula is activated and continuously rotated and stirred for a cleaning time ranging from 0 seconds to 70 or 80 seconds (S420). The stirring part of the spatula scrapes the bottom and lower inner wall of the pot with an interference fit, and the auxiliary spatula scrapes the upper inner wall of the pot. During this process, the water addition process may still be in progress, so water is added and stirred simultaneously until the set water addition time is reached, at which point water addition is stopped (S430). After the cleaning time is completed, the spatula stops stirring and is raised to the highest position inside the pot (S440). Then, the spatula is started and continuously rotated and stirred for a cleaning time ranging from 0 seconds to 70 or 80 seconds (S450). After that, after the cleaning time is completed, the spatula is lowered to the lowest position inside the pot, heating is stopped, and the regular cleaning procedure ends (S460).

[0143] Please refer to Figure 18In applications where an enhanced cleaning procedure is selected based on the degree of contamination, after the lid is closed, the spatula is lowered to the lowest position inside the pot (S500). Water is added to the pot for 190 or 200 seconds, and the pot is then heated (S510). In this step, heating can be selectively performed at maximum power, and water can be added at minimum flow rate to ensure sufficient steam is generated inside the pot. For example, a power of 1800W to 2000W combined with a flow rate of 4 to 6 ml / s allows water to continuously generate steam inside the pot. Therefore, the maximum power and minimum flow rate described in this application can be defined as a combination of power and flow rate that allows water to continuously generate steam inside the pot. After the above steps are completed, a predetermined time is waited for (S520) to allow steam to be generated inside the pot, softening the residue inside. The predetermined time ranges from greater than 0 seconds to less than or equal to 100 seconds, such as 45 seconds, 60 seconds, or 90 seconds. Next, the spatula is activated and continuously rotated and stirred for a cleaning time ranging from 0 seconds to 90 or 100 seconds (S530). The stirring part of the spatula scrapes the bottom surface and the lower inner wall of the pot body with an interference fit, and the auxiliary spatula scrapes the upper inner wall of the pot body. During this process, the water addition process may still be in progress, so water is added to the pot while stirring, until the water addition time reaches the set value, at which point water addition stops (S540). When the cleaning time ends, the spatula stops stirring and is raised to the highest position in the pot body (S550). Then, the spatula is activated again and continuously rotated and stirred for a cleaning time ranging from 0 seconds to 90 or 100 seconds (S560). Afterwards, when the cleaning time ends, the spatula is lowered to the lowest position in the pot body, heating is stopped, and the enhanced cleaning program ends (S570).

[0144] Please refer to Figure 19 To better remove residues adhering to the lid and body of the pot, this application also provides a cleaning method in its embodiments, wherein the cleaning of the lid and the pot body can be performed separately. In the cleaning method for the bottom and inner wall surfaces of the pot body, the step of activating a spatula and stirring and cleaning within a first-value range of cleaning time further includes: Move the spatula to the second cleaning position and reduce its rotation speed to the minimum (S600), for example, 35-45 rpm. This means first moving the spatula away from the target area. In this embodiment, the spatula is first raised to the highest position inside the pot. Then, move the spatula towards the first cleaning position while increasing the rotation speed (S610), causing the spatula to rotate and stir from the highest position to the lowest position inside the pot, gradually increasing the rotation speed. In this embodiment, the rotation speed range can be, but is not limited to, 20-100 rpm. When the spatula contacts the bottom surface of the pot, increase the rotation speed to the maximum (S620), for example, 65-75 rpm. In this way, after the spatula rotates once inside the pot, it will evenly clean a portion of the bottom and inner wall of the pot. Furthermore, during the step of increasing the rotation speed to the maximum, the control module detects whether the rotation speed is at its maximum when the spatula contacts the bottom surface of the pot. If not, repeat the step of continuously moving the spatula towards the lowest position inside the pot until the rotation speed is at its maximum; if so, proceed to the next step.

[0145] Next, the spatula is moved towards the second cleaning position while the rotation speed is reduced (S630). This step serves as a buffer; if the spatula has not yet returned to the highest position inside the pot, it continues to move towards the highest position inside the pot while reducing the rotation speed until the spatula reaches the highest position inside the pot. The spatula can repeat the aforementioned steps of moving towards the first cleaning position and gradually increasing the rotation speed, ensuring that the starting angle of the spatula's pull-up is different for each rotation inside the pot, until all areas on the bottom surface and the lower inner wall surface of the pot are scraped. Therefore, in other embodiments of this application, a confirmation procedure can be performed after each rotation of the spatula to determine whether the cleaning range on the bottom surface is fully covered. If the determination result is negative, the process returns to the step of moving the spatula to the second cleaning position and performs the corresponding steps. If the determination result is positive, the spatula can be selectively moved at a constant speed inside the pot, contacting the inner wall surface and bottom surface of the pot and rotating and scraping evenly for one rotation as a finishing touch. Afterward, the spatula returns to the second cleaning position, stirring is stopped (S640), and the cleaning process ends.

[0146] It is understood that the cleaning method for the inner surface of the lid in this embodiment is similar to the cleaning method for the bottom and inner wall surfaces of the pot described above. The difference lies in the opposite starting position and direction of movement of the spatula. Therefore, in the cleaning method for the inner surface of the lid, the step of activating the spatula and stirring during the cleaning time within the second value range includes: moving the spatula assembly to the first cleaning position and reducing the spatula speed to the minimum; moving the spatula towards the second cleaning position while increasing the speed; bringing the spatula into contact with the inner surface of the lid and increasing the speed to the maximum; moving the spatula assembly towards the first cleaning position while reducing the speed; and returning the spatula assembly to the first cleaning position and stopping stirring. The details are the same as or similar to the cleaning method for the bottom and inner wall surfaces of the pot described above, and will not be repeated here.

[0147] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
