Description

Stir-frying component and cooking equipment for guiding and stir-frying materials Technical Field

[0001] The present invention relates to a stir-frying component for cooking materials and a cooking device, and more particularly to a stir-frying component for guiding and stir-frying materials on an automatic or semi-automatic cooking device and a cooking device. Background Art

[0002] Cooking equipment used to prepare Chinese dishes is usually equipped with a stirring or stir-frying device, which is used to stir the ingredients during the cooking process to ensure that they are fully in contact with the pot and oil or to prevent the ingredients from clumping.

[0003] A stir-frying mechanism used in existing cooking equipment includes a stir-frying shaft and a stir-frying shovel. The stir-frying shovel rotates about a substantially horizontal stir-frying shaft, scooping up food from the pot and throwing it back into the pot. Although this stir-frying mechanism can scoop up food from the pot, the food can only be thrown back into the pot in clumps, or most of the food on the stir-frying shovel is thrown together. Once it falls back into the pot, it is difficult to move widely and spread out fully, thereby affecting the stir-frying effect.

[0004] Chinese patent application 201711089954.4 discloses an artificial stir-fry simulation cooking robot and a cooking method thereof, which includes a pot body, a special-shaped spatula, a push rod and a driving device, wherein the push rod and the driving device are respectively connected to the special-shaped spatula and cooperate to drive the special-shaped spatula to switch between a first stir-fry process and a second stir-fry process; wherein, in the first stir-fry process, the push rod does not contact the inner wall, while the cutting edge of the special-shaped spatula remains in contact with the inner wall and slides from its entry point position with the inner wall to the bottom position of the pot body, and the angle between the shovel surface of the special-shaped spatula and the pot mouth plane of the pot body gradually decreases; in the second stir-fry process, along with the rotation of the special-shaped spatula, the position of the push rod also changes continuously, and gradually changes from not contacting the inner wall of the pot body to its free end contacting the inner wall. At the same time, the inner wall generates a reaction force on the push rod, while the special-shaped spatula does not contact the inner wall, and the special-shaped spatula flips from the bottom position to the entry point position.

[0005] While the aforementioned cooking equipment and its stirring system can avoid the problems of material jamming and chipping that can easily occur when there's a gap between the spatula's blade and the pot's inner wall, as well as preventing sticking, the lever's design can easily damage the pot's inner wall, particularly the inner coating. The stirring portion of the pot doesn't fit well with the pot's inner wall. Limited by the lever's length, the spatula's rotation range is limited, causing material to fall and accumulate in a small area near the rotating shaft, making it difficult to disperse the material away from the rotating shaft and into other areas, especially to disperse it over a larger area where there's no material or less material. Material near the pot can't be scooped up and will stick to the edge, resulting in inadequate heating or even undercooking.

[0006] Summary of the Invention

[0007] One of the purposes of the present invention is to provide a cooking device and a stir-frying component with a simple and reliable structure and better stir-frying effect.

[0008] Another object of the present invention is to provide a cooking device and a stir-frying component that can control the landing point of materials during stir-frying.

[0009] On the one hand, in order to achieve the inventive object of the present invention, the present invention provides an automatic or semi-automatic cooking device for guiding and stir-frying ingredients, the cooking device comprising a pot device and a stir-frying device; the pot device comprises a round pot with an upward opening and a pot rotating device for driving the pot to rotate on a horizontal plane around the central axis of the pot; the stir-frying device comprises a support frame, a stir-frying drive device and a stir-frying member, the stir-frying drive device further comprises a rotating bracket horizontally hinged on the support frame, and the stir-frying member further comprises a stir-frying shovel and a stir-frying rotating shaft; the stir-frying rotating shaft is connected to the stir-frying drive device and drives the stir-frying shovel to move, so that the stir-frying shovel can simultaneously swing up and down around the rotating axis of the rotating bracket during the process of rotating around the stir-frying rotating shaft;

[0010] The stir-fry shovel includes a shovel body for scooping materials from the cookware. A shovel mouth is provided on one side of the shovel body for contacting or scooping materials close to the inner wall of the cookware, and a material guide portion is provided on at least part of the other side edges for guiding the movement direction of the materials. The material guide portion can temporarily delay the falling of the scooped materials and guide and scatter the materials as the stir-fry shovel moves.

[0011] The extension direction of the shovel mouth is substantially parallel to the extension direction of the stir-frying shaft;

[0012] Among them, the extension direction of the stir-fry axis is inclined downward;

[0013] The stir-fry driving device and the stir-fry rotating shaft can swing when the stir-fry shovel moves along the inner wall of the pot.

[0014] It is worth noting that the so-called guided scattering means that the material is scattering along the specific direction guided by the material guide part, and during the scattering process, the material falls one after another; the so-called swinging is relatively free swinging within a certain range to prevent hard interference between the stir-fry spatula and the inner wall of the pot, and to form a better scattering curve.

[0015] As a specific embodiment of the cooking device of the present invention, the stir-fry drive device includes a track-changing cam arranged on the stir-fry rotating shaft and a support member for movably supporting the track-changing cam, wherein the stir-fry rotating shaft is connected to the track-changing cam to enable the stir-frying shovel to swing up and down around the rotation axis of the rotating bracket while rotating around the stir-fry rotating shaft.

[0016] In the above-mentioned specific embodiment, the track-changing cam is provided with a fitting shoveling section corresponding to the shoveling action of the stir-frying shovel and a scattering section corresponding to the throwing action of the stir-frying shovel; when the track-changing cam rotates to the point where the fitting shoveling section contacts the support, the stir-frying shovel rotates to a position close to or contacting the inner wall of the pot, and the track-changing curved surface of the fitting shoveling section interacts with the support, driving the stir-frying shovel to move along / stick to the inner wall of the pot to scoop up the material; when the track-changing cam rotates to the point where the scattering section contacts the support, the stir-frying shovel rotates to a position away from the inner wall of the pot, and the track-changing curved surface of the scattering section interacts with the support, driving the stir-frying shovel to rotate along the scattering curve to throw the scooped material back into the pot.

[0017] It is worth noting that since there is no restriction on the rod, the cam surface can be designed according to the shape of the inner wall of the pot, so that the stir-fry spatula can better fit the inner wall of the pot, and the spatula can be put into the pot as close to the edge as possible, and can be lifted off the pot as close to the edge as possible, thus achieving a wide range of stir-frying.

[0018] In the above-mentioned specific embodiment, the stir-fry drive device is horizontally hinged on the support frame, and the track-changing cam set on the stir-fry shaft is movably supported by the support member. The stir-fry component rotates around the stir-fry shaft and simultaneously swings up and down around the rotation axis of the rotating bracket, so that the stir-fry shovel has a motion trajectory that matches the inner wall of the pot and scoops up the material. This embodiment has the advantages of simple and reliable structure and can achieve a good material stir-frying effect. Using the support member to support the track-changing cam and the stir-fry mechanism can also reduce or even avoid the stir-fry shovel scratching the pot. Those skilled in the art will understand that the track-changing cam is only a specific way to achieve the stir-fry component to swing up and down around the rotation axis of the rotating bracket while rotating around the stir-fry shaft.

[0019] Preferably, the rotation radius of the above-mentioned scattering section is smaller than the rotation radius of the fitting shoveling section; in this way, when the track-changing cam rotates to the point where the fitting shoveling section contacts the support, the stir-frying shovel rotates into the cooking pot to stir-fry the materials; when the track-changing cam rotates to the point where the scattering section contacts the support, the stir-frying shovel rotates above the cooking pot to scatter the scooped materials back into the cooking pot.

[0020] In this specific embodiment, the rotation radius of the scattering section is smaller than the rotation radius of the shoveling section, which makes the stir-fry shovel have a relatively low height when scattering the material, which makes it easier to accurately scatter the material back into the cooking pot, avoiding the problem that the material cannot fall accurately back into the pot or is even thrown out of the pot, affecting the stir-frying effect, and allows the stir-fry shovel to quickly return to the cooking pot for the next stir-frying operation.

[0021] The cooking device of the present invention also includes a scraper, which is arranged on a device that does not rotate with the pot. When the pot rotates, it remains stationary or moves relative to the pot, and is close to or in contact with the inner wall of the pot, so that the material moves toward the center of the pot. Preferably, the extension direction of the scraper and the line connecting the upper end of the scraper and the center of the pot are not parallel, but are arranged to be inclined in the direction of rotation of the pot.

[0022] Preferably, in the cooking apparatus of the present invention, the stir-frying device further comprises a baffle / retainer ring for use with the stir-frying shovel, the baffle / retainer ring being disposed at least on the side of the cooking pot where the stir-frying shovel is removed. The track-changing cam further comprises a lifting portion between the contact shoveling section and the scattering section. When the stir-frying shovel approaches the inner wall of the baffle / retainer ring (contacting or substantially contacting the inner wall of the baffle / retainer ring) and rotates upward to lift the material, the track-changing cam rotates until the lifting portion contacts the support member. The baffle / retainer ring can encourage the stir-frying shovel to lift more material above the pot for scattering, achieve a better material return effect, and prevent material from scattering outside the pot from the side where the stir-frying shovel is removed.

[0023] The aforementioned retaining plate / retaining ring may be independent of the cookware, or may be an extension of the cookware itself (e.g., an integrated cookware). In certain embodiments of the present invention, the retaining plate / retaining ring may be fixedly or removably attached to the edge of the cooking pot. As a specific embodiment, the retaining plate / retaining ring may be horizontally hinged to the shaft of the support frame or rotating bracket.

[0024] Furthermore, in the cooking device of the present invention, the rotating bracket has a first linkage portion and a second linkage portion; when the rotating bracket is flipped to move the stir-fry component to a working position where it can enter the cooking pot, the first linkage portion drives the blocking piece / blocking ring to move to a position that contacts or is close to the edge of the cooking pot; when the rotating bracket is flipped to move the stir-fry component away from the working position, the second linkage portion drives the blocking piece / blocking ring to move away from the cooking pot.

[0025] In the cooking device of the present invention, the inner wall of the pot is composed of at least two curved surfaces with different curvatures. The first curved surface is a fitting shoveling portion, which extends outward and obliquely upward from the bottom of the pot with a smaller curvature. The second curved surface is a turning portion, which starts from the end of the fitting shoveling portion and gradually retracts inward toward the central axis of rotation of the pot with a larger curvature, and then extends inward and obliquely upward. The material is scooped up by the stir-frying shovel in the fitting shoveling portion and partially or completely turned over in the turning portion.

[0026] Furthermore, in the cooking device of the present invention, the curve of the track-changing cam is designed according to the curved surface shape and curvature change of the inner wall of the pot, so that the track-changing cam rotates and drives the stir-fry spatula to move along the inner wall of the pot to maintain good proximity / contact with the inner wall of the pot.

[0027] In the cooking device of the present invention, when the stir-frying shovel enters the pot and approaches or contacts the inner wall of the pot, the center of the stir-frying shovel body deviates from the center of the pot, so that the stir-frying shovel can scoop up materials in one area and then scatter them to other areas; preferably, the center of the stir-frying shovel body deviates from the center of the pot in the direction of the stir-frying drive device, so that the stir-frying shovel can scoop up part of the materials from the area close to the stir-frying drive device and then scatter them to the area away from the stir-frying drive device.

[0028] Preferably, in the cooking device of the present invention, in the scattering section, the stir-fry shaft is restricted to swing within a downwardly inclined range, so that the material scooped up by the stir-fry shovel moves away from the stir-fry drive device when the stir-fry shovel moves, and is thrown back into the pot in a scattering manner as the stir-fry shovel moves and flips.

[0029] Further preferably, in the cooking device of the present invention, the stir-fry shaft swings within an angle range of -5 degrees to -20 degrees with the horizontal line, so that the curvature of the scattering curve is not too large and the material is not easily scattered outside the pot.

[0030] As another specific embodiment of the cooking device of the present invention, the stir-fry shovel has a shovel mouth formed on the side of the shovel body that contacts the inner wall of the pot, and a material guide portion is provided on at least one other side of the shovel body to guide the direction of material movement, and the material guide portion is biased toward the outside of the shovel body and is arranged obliquely upward.

[0031] On the other hand, in order to achieve the above-mentioned purpose of the invention, the present invention also provides a stir-fry component for automatic or semi-automatic cooking equipment, which includes a stir-fry shaft and a stir-fry shovel connected to the stir-fry shaft, wherein the stir-fry shaft is connected to the stir-fry driving device in the above-mentioned cooking equipment and drives the stir-fry shovel to move; the stir-fry shovel includes a shovel body for scooping materials from the pot, and a shovel mouth close to or in contact with the inner wall of the pot is provided on one side of the shovel body, and a material guiding part inclined toward the outside of the shovel body and upward is provided on at least part of the other side edges.

[0032] In the design of the stir-frying component, the material guide portion guides the material scooped up by the stir-frying shovel to a position relatively deviated from the center of the pot and spreads the re-added material to prevent the accumulation of the material and facilitate the rapid dispersion of the material.

[0033] In one embodiment of the stir-frying mechanism of the present invention, a material guide is disposed on the side of the shovel body away from the stir-frying axis, and is positioned outward and upward relative to the shovel body. This arrangement is particularly advantageous because, when the stir-frying shovel enters the cookware and contacts the inner wall, one side of the shovel body is positioned near the center of the cookware, while the other side is positioned away from the center. This allows the side of the shovel body away from the stir-frying axis to cut into the introduced material and separate it. In this case, the material guide provided on this side of the shovel body improves the separation effect. Furthermore, the material guide disposed on the side of the shovel body away from the stir-frying axis can also effectively delay the premature fall of material moving away from the stir-frying drive device.

[0034] In the stir-frying component of the present invention, the material guiding part may include a main material guiding block and an auxiliary side block; the main material guiding block and the auxiliary side block are arranged on at least one side of the shovel body adjacent to or relative to the shovel mouth, wherein the height of the main material guiding block is greater than the height of the auxiliary side block, and the angle between the main material guiding block and the shovel body is not less than the angle between the auxiliary side block and the shovel body.

[0035] In the stir-frying component of the present invention, the height of the main material guide guard refers to the distance that the main material guide guard extends upward from the shovel body when the shovel body of the stir-frying shovel is placed flat on a horizontal plane, and the height of the auxiliary side guard refers to the distance that the auxiliary side guard extends upward from the shovel body when the shovel body of the stir-frying shovel is placed flat on a horizontal plane.

[0036] In the stir-frying component of the present invention, since the material guiding part includes at least one material guiding main block and at least one auxiliary side block, this helps the stir-frying shovel to scoop up more materials from the pot for scattering; and the height of the material guiding main block is greater than the height of the auxiliary side block, which helps to achieve a better material scattering effect: the inventors found that in automatic / semi-automatic cooking equipment, if the material guiding main block has a higher height, the material scattering range can be increased; similarly, the inventors found that in automatic / semi-automatic cooking equipment, if the angle between the material guiding main block and the shovel body is not less than the angle between the auxiliary side block and the shovel body, it facilitates further spreading of the material on the material guiding main block during the scattering process.

[0037] In the stir-frying mechanism of the present invention, the stir-frying shovel rotates about the stir-frying axis, scooping up material from the pot, then rotating it over the pot and scattering the material back into the pot. During this scattering process, because the height of the inclined main guide block is shorter than the length of the shovel body itself, a portion of the material on the shovel body slides onto the main guide block, spreading the material more widely on the stir-frying shovel and creating a height difference. The material is then scattered back into the pot by the stir-frying shovel in stages and in phases. After leaving the stir-frying shovel, the material is further dispersed and spread more widely and thinly within the pot, thereby achieving a better stir-frying effect.

[0038] Preferably, in the stir-frying component of the present invention, the shovel body and / or the material guide portion may be provided with one or more stirring teeth. The stirring teeth may serve to disperse / break up and / or guide the material. More preferably, the stirring teeth are provided near the shovel opening and / or on the auxiliary side guard.

[0039] In one embodiment of the stir-frying mechanism of the present invention, the width of the main material guide gradually decreases along its height. This facilitates dispersing material that has slid onto the main material guide back into the cookware in a timed and segmented manner, thereby further dispersing the material. For example, the main material guide can be tilted toward one or both of the two adjacent ends of the shovel opening, thereby better facilitating the dispersal of material from one or both ends of the main material guide.

[0040] In the stir-frying component of the present invention, in the width direction of the main material guiding block, the middle portion of the main material guiding block can also be made higher or lower than the two ends of the main material guiding block.

[0041] In another embodiment of the stir-frying mechanism of the present invention, a main material guide includes a first and a second main material guide extending sequentially from the shovel body. The angle between the second main material guide and the shovel body is greater than the angle between the first and the shovel body. This allows a portion of the material to escape from the stir-frying shovel and disperse away from the direction of rotation of the stir-frying shovel, further enhancing the stir-frying effect. The surface between the first and second main material guides can be either folded or curved, and the main material guide itself can also be flat or curved.

[0042] Furthermore, in the width direction of the material guiding main stop, one side of the material guiding main stop is higher than the other side.

[0043] Furthermore, the shovel body is arranged to be inclined toward the downstream side of the stir-frying rotation direction, so as to scoop up more materials during the stir-frying rotation process; the material bearing surface of the shovel body is raised toward the downstream side of the stir-frying rotation direction, which is conducive to further improving the material scattering effect.

[0044] Furthermore, an auxiliary side block is also provided on the side where the shovel body is connected to the stir-fry shaft. The auxiliary side block is arranged to be inclined toward the outside of the shovel body, so that the auxiliary side block plays an auxiliary guiding role for the material during the process of scattering the material, so that the material is scattered more widely.

[0045] More specifically, the material guiding main stop is arranged obliquely upward on the side away from the shovel mouth.

[0046] Furthermore, the width of the main material guide block gradually decreases in the height direction of the main material guide block, which is conducive to throwing the material that slides onto the main material guide block back into the cooking pot in time and section by section, so that the material is more widely distributed.

[0047] Furthermore, in the width direction of the main material guiding block, the middle portion of the main material guiding block is higher or lower than both ends of the main material guiding block.

[0048] Furthermore, the main material guide block is inclined toward one or both sides of the adjacent two sides of the shovel mouth, so as to better enable the material to be thrown from one or both sides of the main material guide block.

[0049] Furthermore, one or more stirring teeth are provided on the shovel body and / or the main material guide block and / or the auxiliary side block, and the stirring teeth can play a role in scattering / breaking up and / or guiding the material.

[0050] During the process of scattering the material by the stir-frying shovel, since the inclined material guide main stop is at a lower height than the shovel body, a part of the material on the shovel body will slide onto the material guide main stop, causing the material to be spread more widely on the stir-frying shovel and forming a height difference, and then the material will be scattered back to the pot by the stir-frying shovel in a timely and segmented manner. After the material leaves the stir-frying shovel, it will be scattered more widely and thinner in the pot, thereby achieving a better stir-frying effect.

[0051] In the cooking device of the present invention, the stir-fry shovel rotates around the stir-fry shaft, and the stir-fry shaft swings within a certain range, shoveling as close to the edge of the pot as possible and leaving the pot as close to the edge of the pot as possible, thereby achieving shoveling and scooping up materials in a larger range close to / contacting the inner wall of the pot. After scooping up the materials from the pot, they are thrown along the specific direction guided by the material guide part to an area without materials or with less materials, thereby achieving a larger range of displacement and scattering. During the scattering process, the materials can fall and spread out one after another. In the process of scattering the materials with the stir-fry shovel, part of the materials on the shovel body will slide onto the material guide plate, so that the materials are spread out more on the stir-fry shovel and a height difference is formed. After the materials leave the stir-fry shovel, they are scattered more and spread out more and thinner in the pot, thereby achieving a better stir-frying effect.

[0052] In order to more clearly illustrate the purpose, technical solutions and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Referring to Figure 1 , a cooking device 1 according to an embodiment of the present invention comprises a box-shaped main body 11 and a cooking pot 12. Cooking pot 12 is rotatably mounted on main body 11. A rotational drive mechanism is disposed within main body 11 to drive cooking pot 12 to rotate about its central axis. In other embodiments of the present invention, cooking pot 12 may be mounted on main body 11 in a non-rotatable manner.

[0061] Mounted on the rear side of the main body 11 is a stir-frying device 2 for stir-frying the cooking materials within the cooking pot 12. The stir-frying device 2 comprises two opposing support frames 21, a drive device 22 disposed between the two support frames 21, and a stir-frying member 23 connected to the drive device 22. The drive device 22 comprises a rotating frame 221 and a motor 222 mounted thereon (see FIG2 ). The rotating frame 221 can be box-shaped, as shown in FIG1 , and the motor 222 can be disposed within the rotating frame 221. Alternatively, the rotating frame 221 can be hinged to the support frame 21 at only one end; in other words, the support frame 21 can be disposed at only one end of the rotating frame 221.

[0062] The rotating bracket 221 is horizontally hinged to the support frame 21 via its rotating shaft 2211, allowing the stir-frying member 23 to rotate between a non-operating position and an operating position shown in Figure 1. In this operating position, the stir-frying member 23 can be driven by the motor 222 to rotate into the cooking pot 12 to stir the cooking ingredients. In the embodiment shown in Figure 1, an operating handle 24 is connected to one end of the rotating bracket 221. When the operating handle 24 is lifted, the rotating bracket 221 flips backward, moving the stir-frying member 23 to the non-operating position. In other embodiments of the present invention, an automatic flipping mechanism connected to the rotating shaft 2111 can also be provided to achieve forward and backward flipping of the rotating bracket 221.

[0063] Continuing with Figure 1 , the edge of the cooking pot 12 is removably provided with a retaining plate / ring 25. This retaining plate / ring 25 is provided with a vertical strip-shaped hole or slot 252 for the stir-fry shaft 231 (see Figure 2 ) to pass through and provide space for the stir-fry shaft 231 to swing up and down. In embodiments of the present invention, the retaining plate / ring may be provided only on the side where the stir-frying shovel is removed from the cooking pot 12, or on both the side where the stir-frying shovel is removed from the cooking pot 12, or even along the entire circumference of the cooking pot 12. The retaining plates / rings on the side where the stir-frying shovel is removed from the cooking pot 12 and the side where the stir-frying shovel is removed from the cooking pot 12 may be integral or interconnected, as shown in Figure 1 , or they may be provided separately. The retaining plate / ring 25 may also be fixedly provided on the edge of the pot 12.

[0064] In this embodiment of the present invention, the baffle / ring 25 can be vertically positioned as shown in Figure 1, or it can be tilted or retracted toward the inside of the pot 12. The inner contour of the vertical cross-section of the baffle / ring 25 can be flat or curved. Furthermore, a scraper 26 can be mounted on the lower edge of the baffle / ring 25. The free end of the scraper 26 is offset downstream in the direction of pot rotation to gather material from the outer periphery of the pot 12 inward during pot rotation. The scraper 26 can also be mounted in other ways, such as being mounted on the main body 11 and extending into the pot 12.

[0065] The baffle / retainer ring 25 can be horizontally hinged to the rotating shaft 2211 of the support frame 21 or the rotating bracket 221. For example, as shown in Figure 1, the baffle / retainer ring 25 is fixedly connected to a connecting member 2212 hinged to the rotating shaft 2211 via a hinge rod 251. The connecting member 2212 is hinged to the rotating shaft 2211. The support frame 21 is provided with corresponding outwardly protruding rear stop 211 and front stop 212. The connecting member 2212 abuts against the front stop 212 to limit the baffle / retainer ring 25 from turning forward to a front limit position. In this front limit position, the baffle / retainer ring 25 contacts or comes into close contact with the edge of the cookware 12. When the connecting member 2212 abuts against the rear stop 211, the baffle / retainer ring 25 is limited to a rear limit position for turning backward. The rear limit position for turning backward of the rotating bracket 221 can be achieved by the rear stop 211 or other rotation-limiting structures.

[0066] The end of the rotating bracket 211 has an outwardly protruding first linkage portion 241 and a second linkage portion 2113. The first linkage portion 241 is connected to the operating handle 24, and the second linkage portion 2113 is located in front of and below the first linkage portion 241. A hinged rod 251 is disposed between the first linkage portion 241 and the second linkage portion 2113. When the rotating bracket 221 is tilted forward to move the stir-frying member 23 to the operating position where it can enter the cooking pot 12, the first linkage portion 241 abuts the hinged rod 251 and drives the blocking piece / ring 25 to a position that contacts or approaches the edge of the cooking pot 12. When the rotating bracket 221 is tilted backward to move the stir-frying member 23 to the non-operating position, the second linkage portion 2113 abuts the hinged rod 251 and drives the blocking piece / ring 25 away from the cooking pot 12.

[0067] As shown in Figures 1 to 3 , the stir-frying member 23 includes a stir-frying shaft 231 and a stir-frying shovel 232. The stir-frying shovel 232 has a shovel body 233 that is tilted toward the downstream side of its stir-frying rotation direction R (see Figure 5 ). The side of the shovel body 233, which is adjacent to the inner wall of the cooking pot 12, forms an arc-shaped shovel opening 2331 that conforms to the shape of the inner wall of the cooking pot 12 to facilitate scooping / scraping of materials. The material-bearing surface of the shovel body 233 (the surface that scoops up materials when rotating in the direction R) can be flat or a curved surface that is convex toward the downstream side of the stir-frying rotation direction R.

[0068] The shovel body 233 has auxiliary side guards 2341 on the sides opposite the shovel opening 2331, and auxiliary side guards 2342 on the sides of the shovel body 233 connected to the stir-fry shaft 231, which are used to lift more ingredients during stir-frying. The auxiliary side guards 2341 and 2342 are preferably arranged to be inclined toward the outside of the shovel body 233, providing auxiliary guidance for the ingredients during scattering, thereby spreading them more widely. The auxiliary side guards 2341 may be provided with one or more stirring teeth 2351. While the stirring teeth 2351 disperse the ingredients, they also guide the ingredients on one side of the auxiliary side guard 2341 during scattering, further spreading the ingredients on that side. One or more stirring teeth 2352 may be provided on the shovel body 233 near the shovel opening 2331. The stirring teeth 2352 are primarily used to disperse the cooking ingredients.

[0069] Furthermore, a main guide block 236 is provided on the side of the shovel body 233 away from the stir-frying shaft 231. As shown in FIG3 , the height of the main guide block 236 is greater than the heights of the auxiliary side blocks 2341 and 2342. The width of the main guide block 236 gradually decreases along its height. Preferably, the angle formed by the main guide block 236 relative to the shovel body 233 is not less than the angle formed by the auxiliary side blocks 2341 relative to the shovel body 233.

[0070] The main material guide stop 236 may include a first main material guide stop 2361 and a second main material guide stop 2362, which extend sequentially from the shovel body 233. The second main material guide stop 2362 has a greater inclination angle relative to the shovel body 233 than the first main material guide stop 2361. In other words, the angle between the second main material guide stop 2362 and the shovel body 233 is greater than the angle between the first main material guide stop 2361 and the shovel body 233.

[0071] As shown in Figure 2, a track-changing cam 24 is mounted on the stir-fry shaft 232 and movably supported on a support member 25. Preferably, the support member 25 is rotatably mounted, forming rolling contact with the track-changing cam 24. When the stir-fry device 2 is in operation, the support member 25 supports the track-changing cam 24, allowing the stir-fry member 23 to simultaneously swing up and down around the rotation axis of the rotating bracket 224 while rotating about the flip shaft 231. This allows the stir-fry shovel 232 to follow a trajectory that matches the inner wall of the cooking pot 12 after entering the cooking pot.

[0072] Figure 4 illustrates the structure of the track-changing cam 24. When the stir-frying member 23 and the track-changing cam 24 rotate in the stir-frying direction R, point A corresponds to the position where the stir-frying shovel 232 enters the cooking pot 12, point B corresponds to the position where the stir-frying shovel 232 exits the cooking pot 12, and point C corresponds to the position where the stir-frying shovel 232 disengages the retaining plate / retaining ring 25. Sections AB of the track-changing cam 24 can be considered the contact shoveling section S1. When the contact shoveling section S1 abuts the support member 25, the stir-frying shovel 232 rotates along the inner wall of the pot from the stir-frying shovel entry side to the stir-frying shovel exit side, scooping material from the cooking pot 12 (as shown in Figure 5).

[0073] When the raised portion (segment BC) of the track-changing cam 24 contacts the support member 25, the stir-fry shovel 232 substantially contacts or approaches the inner wall of the baffle / retainer ring 25, rotating upward and further raising the material to a certain height to spread it over a wider area. After passing point C, the spreading segment S2 (segment CA) of the track-changing cam 24 contacts the support member 25, at which point the stir-fry shovel 232 disengages from the baffle / retainer ring 25 and rotates over the cooking pot 12, scattering the material back into the cooking pot 12. As shown in FIG6 , during the process of the stir-fry shovel 23 rotating over the pot 12 to scatter the material, the first and second main material guide stops 2361, 2362 are located below the shovel body 233. A portion of the material slides from the shovel body 233 to the first and second main material guide stops 2361, 2362, allowing the material to be gradually scattered back into the pot 12 in a timed and segmented manner, spreading it more widely and thinly within the pot 12, thereby achieving a better stir-frying effect.

[0074] Among them, the rotation radius of the scattering section S2 is preferably set to be smaller than the rotation radius of the fitting shoveling section S1, so as to reduce the rising height of the stir-frying shovel 232. On the one hand, this allows the stir-frying shovel 232 to have a relatively low height when scattering materials, which is convenient for accurately scattering the materials back into the cooking pot 12, avoiding the stir-frying effect being affected by the inability of the materials to accurately fall back into the pot 12. On the other hand, the stir-frying shovel 232 can quickly return to the cooking pot 12 for the next stir-frying operation.

[0075] When the stir-fry shovel 232 rotates to the approximate center of the cookware 12, the stir-fry shaft 231 is approximately horizontal (see FIG5 ). Because the rotation radius of the scattering section S2 is smaller than the rotation radius of the contact shoveling section S1, when the stir-fry shovel 232 rotates above the cookware, the stir-fry shaft 231 is tilted downward (see FIG6 ). This facilitates the sliding of the material on the shovel body 233 onto the main material guide 236, thereby further dispersing the material.

[0076] In other embodiments of the present invention, the auxiliary side guards 2341 and 2342 can also be replaced with main material guide guards; that is, the main material guide guard is provided on at least one side of the shovel body 233, excluding the shovel opening 2331. The main material guide guard can be formed as a flat surface, an arcuate surface, or a combination of a flat surface and an arcuate surface. The connection between the main material guide guard and the shovel body 233 can form an edge or a curved transition.

[0077] Figures 7a-7d illustrate schematic diagrams of structures in which different structures of material guide main stops are provided on the side of the shovel body 233 opposite the shovel mouth. In the embodiment of Figure 7a, the material guide main stop 1236 can be tilted relative to one of the two adjacent sides of the shovel mouth; in the embodiment of Figure 7b, the material guide main stop 2236 can be tilted relative to the other of the two adjacent sides of the shovel mouth, and can have an asymmetrical structure with one side higher and one side lower; in the embodiment of Figure 7c, the material guide main stop 3236 has a tower-like structure with a high center and low sides, and the two sides of the material guide main stop 3236 are tilted toward opposite sides of the shovel mouth; in the embodiment of Figure 7d, the material guide main stop 4236 has a dovetail structure with high sides and a low center, and the two sides of the material guide main stop 4236 are also tilted toward opposite sides of the shovel mouth.

[0078] In an embodiment of the present invention, the outer profile of the track-changing cam 24 can be formed so that after entering the cooking pot 12, the stir-fry shovel 232 always remains close to the inner wall of the cooking pot 12, or only stays close to the inner wall of the cooking pot 12 during a portion of the rotation stroke, for example, only stays close to the inner wall of the cooking pot 12 in the material accumulation area near the bottom of the cooking pot 12.

[0079] In addition, the stir-frying component 23 can also be driven by the motor 222 to rotate in the opposite direction of the stir-frying rotation direction R. When the stir-frying component 23 rotates in the opposite direction, there is a relatively small angle between the shovel body 233 and the inner wall of the pot (see Figure 5). On the one hand, this can apply extrusion pressure to the material to disperse the clumped material, and on the other hand, it can also stir-fry the material to a certain extent.

[0080] Although the present invention has been disclosed above with reference to specific embodiments, these embodiments are not intended to limit the scope of the present invention. Any person skilled in the art may make modifications or substitutions without departing from the scope of the present invention. In other words, any equivalent modifications made in accordance with the present invention are intended to be covered by the scope of protection of the present invention.
