Description

Technical Field

[0001] The present invention relates to the technical field of small household appliances, and in particular to a stirring assembly and a cooking utensil having the same. Background Art

[0002] The cooking utensil comprises a pot body and an upper cover which is openably and closably arranged on the pot body. Food can be cooked by putting it into a cooking cavity of the pot body, and the upper cover is arranged on the pot body to seal the cooking cavity of the pot body.

[0003] In the related art, a stirring component is provided in the cooking cavity of the pot body. During the cooking process, the food is stirred by the stirring component to improve the cooking effect of the food.

[0004] However, the stirring assembly in the related art has the problem of poor stirring effect. Summary of the Invention

[0005] The present invention provides a stirring component and a cooking utensil having the same, so as to solve the problem of poor stirring effect of the stirring component in the related art.

[0006] According to one aspect of the present invention, a stirring assembly is provided, which is arranged in a pot body, and the stirring assembly includes: a rotating base, which is rotatably arranged in the pot body around its vertical axis, and a fixed blade is fixedly connected to the side wall of the rotating base; a stirring blade, which includes a horizontal axis and a stirring blade arranged on the horizontal axis, and the horizontal axis passes through the side wall of the rotating base, and the horizontal axis can rotate around its axis relative to the rotating base; wherein, in the direction from top to bottom, the rotation direction of the rotating base is clockwise, and in the direction from the horizontal axis away from one end of the rotating base to the direction close to the other end of the rotating base, the rotation direction of the horizontal axis is counterclockwise; or, in the direction from top to bottom, the rotation direction of the rotating base is counterclockwise, and in the direction from the horizontal axis away from one end of the rotating base to the direction close to the other end of the rotating base, the rotation direction of the horizontal axis is clockwise.

[0007] According to the technical solution of the present invention, the stirring assembly includes a rotating base and a stirring blade. When the rotating base rotates, it drives the fixed blade and the stirring blade to orbit around the vertical axis of the rotating base. The fixed blade and the stirring blade of the stirring blade can stir the food in the cooking cavity circumferentially, causing the food to move circumferentially (around the bottom wall and circumferential side walls) within the cooking cavity. Furthermore, as the rotating base rotates, the horizontal axis of the stirring blade rotates relative to the rotating base, driving the stirring blade to rotate around its axis. The stirring blade can stir the food in the cooking cavity vertically, causing the food to flip upside down. With this structure, when the rotating base rotates, the fixed blade and the stirring blade stir the food in the cooking cavity circumferentially, causing the food to move circumferentially. Simultaneously, the stirring blade flips and stirs the food in the cooking cavity vertically. This causes the food to both move circumferentially and flip vertically within the cooking cavity, thereby achieving three-dimensional stir-frying of the food in the cooking cavity. This improves the stir-frying uniformity of the food and enhances the stirring effect of the stirring assembly on the food. Furthermore, since the rotation direction of the rotating base is clockwise from top to bottom, the rotation direction of the horizontal axis is counterclockwise in the direction from the end of the rotating base away from the rotating base to the end close to the rotating base; and since the rotation direction of the rotating base is counterclockwise from top to bottom, the rotation direction of the horizontal axis is clockwise in the direction from the end of the rotating base away from the rotating base to the end close to the rotating base, when the fixed blade and the stirring knife are used to flip the food circumferentially, since the rotation direction of the stirring knife is opposite to the rotation direction of the rotating base (clockwise / counterclockwise), the stirring knife is easier to flip the food, the food is flipped more in the cooking chamber, the food is heated evenly, and the three-dimensional stirring effect of the stirring assembly on the food can be further enhanced.

[0008] Furthermore, the stirring assembly includes a fixed gear and a movable gear. The fixed gear has a horizontally arranged ring gear and is locked in rotation with the pot body or a cover mounted on the pot body. The movable gear is disposed on a horizontal shaft and meshes with the ring gear. The meshing transmission method of the fixed and movable gears transmits the torque of the rotating base to the horizontal shaft, converting the vertical rotation of the rotating base into horizontal rotation of the horizontal shaft, causing the horizontal shaft to simultaneously rotate horizontally while following the circumferential revolution of the rotating base.

[0009] Furthermore, the rotating base has a downwardly extending mounting hole, within which both the fixed gear and the moving gear are located, with the fixed gear engaged with the pot body to prevent rotation; and / or, the rotating base has a downwardly extending vertical shaft, with the pot body's driving member connected to the vertical shaft in driving relationship, the fixed gear having a clearance hole extending from top to bottom to allow the vertical shaft to pass through, and the gear ring is disposed around the periphery of the clearance hole. The mounting hole of the rotating base can accommodate the fixed gear and the moving gear, preventing them from being exposed and improving the integrity of the stirring assembly. By providing the clearance hole and extending the vertical shaft through the clearance hole, a driving connection between the driving member and the rotating base is achieved.

[0010] Furthermore, the rotating base has a downwardly extending mounting hole, and a support boss is provided on the inner sidewall of the rotating base. The fixed gear is mounted on the support boss, and the lower end of the fixed gear protrudes downward from the support boss and engages with the pot body to prevent rotation. The support boss provides support for the fixed gear, ensuring its assembly within the rotating base and preventing it from falling.

[0011] Furthermore, the fixed gear includes a shaft diameter section and a flanged platform. The flanged platform is disposed at the upper end of the shaft diameter section, and the lower end of the shaft diameter section is engaged with the pot body for rotation prevention. The support boss and flanged platform are both annular structures, with the ring gear disposed on the upper surface of the flanged platform, and the lower surface of the flanged platform resting on the upper surface of the support boss. The fixed gear is resting on the support boss via the flanged platform. Since both the support boss and the flanged platform are annular structures, the support area of ​​the fixed gear is increased, thereby improving the stability of the fixed gear within the rotating base during rotation.

[0012] Furthermore, the lower end of the fixed gear is fixedly connected to the pot body, and the rotating seat is rotatably covered on the outer side of the fixed gear. The above structure has the advantage of being easy to process.

[0013] Furthermore, the ratio of the rotation speed of the rotating base to the rotation speed of the horizontal axis is between 1:1 and 1:3, and the stirring blades have a sufficiently high rotation speed, which can improve the stir-frying effect while simplifying the number of stirring blades.

[0014] Furthermore, a shaft hole is provided on the side wall of the rotating base. The rotating base has a downwardly extending vertical shaft. The driving member of the pot body is drivingly connected to the vertical shaft. The vertical shaft has a through hole extending horizontally, and the horizontal shaft extends through the shaft hole and the through hole. With this structure, the shaft hole and the through hole can be used to assemble the horizontal shaft. The rotation of the vertical shaft drives the horizontal shaft, which in turn rotates around the ring gear through the moving gear, achieving circumferential stirring and vertical flipping of the food by the stirring blade.

[0015] Furthermore, the fixed blades are lower than the horizontal axis and cooperate with the bottom wall of the cooking cavity of the pot body. When the rotating base rotates, the fixed blades can stir the food that falls on the bottom wall of the pot body, thereby reducing the probability of food getting stuck on the bottom.

[0016] Furthermore, the stirring blade and the fixed blade are respectively located on two opposite sides of the rotating base. The stirring effect can be further improved by cooperating with the stirring blade and the fixed blade.

[0017] Furthermore, the stirring blade includes a first blade, which includes a horizontal section and a bent section that are connected to each other. The horizontal section is connected to the horizontal axis, and the bent section cooperates with the side walls and bottom wall of the cooking cavity of the pot body. When the rotating seat rotates, the first blade can follow the rotating seat and rotate around the circumferential direction of the pot body with the axis of the rotating seat as the axis (that is, the first blade can revolve). At the same time, the first blade can also rotate around the horizontal axis (that is, the first blade can rotate on its own) to achieve the flipping of the food. When the first blade revolves, the bent section can cooperate with the side wall of the cooking cavity, and at this time, the bent section can push the food adhered to the side wall of the cooking cavity to move. When the first blade rotates, the bent section can push the food adhered to the bottom wall of the cooking cavity and can stir-fry the food, thereby reducing the probability of long-term contact between the food and the inner wall of the pot body, improving the uniformity of heating the food, and thus improving the uniformity of the taste of the food.

[0018] Furthermore, the bent section includes a first plate section connected to the horizontal section and a second plate section connected to the first plate section. The first plate section extends vertically and engages with the side walls of the cooking cavity of the pot body, while the second plate section is spaced apart from the horizontal section and engages with the bottom wall of the cooking cavity of the pot body. This structure facilitates the bent section to scrape food stuck to the inner wall and bottom wall of the cooking cavity and cause the food to flip, thereby reducing the probability of food being trapped on the side walls or bottom wall of the cooking cavity and promoting a more uniform taste of the food.

[0019] Furthermore, the end of the second plate segment away from the first plate segment is offset relative to the horizontal segment in the circumferential direction of the rotating seat. The above structure enables the second plate segment to contact the food first, the first plate segment to contact the food second, and the horizontal segment to contact the food last when the first blade rotates. The above method can improve the smoothness of the rotation of the first blade and reduce the probability of the first blade being stuck by food. Specifically, if the horizontal segment, the first plate segment, and the second plate segment of the first blade are in contact with food at the same time, the resistance of the first blade during rotation will increase, making it easy for the first blade to be stuck by food.

[0020] Furthermore, the stirring blade includes a second blade. The first blade and the second blade are located at the same end of the horizontal axis, and the second blade is spaced apart from the horizontal section in the circumferential direction of the horizontal axis. In this structure, food stuck to the side walls and bottom wall of the cooking cavity can be flipped as the first blade rotates, and food in the middle of the pot can be flipped as the second blade rotates, thereby further improving the uniformity of heating of the food within the pot and ensuring the food's taste.

[0021] Furthermore, the stirring blade includes a third blade and a fourth blade connected to one end of the horizontal axis, each of which is an arc-shaped structure and is centrally symmetrically arranged relative to the horizontal axis. Since the third blade and the fourth blade are both arc-shaped, when the stirring assembly is in operation, the third blade and the fourth blade can scoop up the ingredients and then throw them back, causing the ingredients to flip over, thereby achieving more thorough stirring of the ingredients, a more uniform stirring effect, and higher stirring efficiency. Furthermore, the arc-shaped structure of the third blade and the fourth blade prevents the edges of the third blade and the fourth blade from coming into linear contact with the ingredients, effectively preventing jamming during the stirring process. Furthermore, since the stirring blade includes both the third blade and the fourth blade, the ingredients can be stirred twice during each rotation of the stirring blade as a whole, greatly improving stirring efficiency and ensuring more uniform heating and cooking of the ingredients. Furthermore, since the third blade and the fourth blade are centrally symmetrically arranged relative to the horizontal axis, the third blade and the fourth blade have the same stirring effect, ensuring that the ingredients are stirred with the same force and speed. Therefore, through the above-mentioned setting, the number of stirring times is increased, the stirring efficiency is greatly improved, and the third blade and the fourth blade have the same stirring effect on the ingredients, so that the stirring device stirs evenly and the user experience is good.

[0022] Furthermore, the stirring blade further comprises a fifth blade connected to the other end of the horizontal shaft. Due to the provision of the fifth blade, the stirring efficiency is further improved while ensuring a good stirring effect of the stirring assembly.

[0023] Furthermore, the fixed blade is located directly below the fifth blade. Since the rotating base is rotatably arranged about its vertical axis, the stirring blade can simultaneously rotate and revolve around the rotating base, achieving vertical stirring of the ingredients and a more uniform stirring effect. At the same time, since the fixed blade is provided and located below the fifth blade, this improves stirring efficiency while achieving vertical stirring of the entire ingredients, resulting in more uniform stirring and higher stirring efficiency.

[0024] Furthermore, the distance between the axis of the horizontal shaft and the bottom wall of the cooking cavity of the pot body is d, and the height of the cooking cavity of the pot body is h, where d≤h / 2. The above structure can maximize the size of the stirring blade, thereby improving the stirring effect.

[0025] Furthermore, the stirring assembly further comprises a first drive motor disposed in the rotating base, the first drive motor being drivably connected to the horizontal shaft. The use of the first drive motor has the advantages of simple structure and easy installation.

[0026] According to another aspect of the present invention, a cooking device is provided, comprising: a pot body having a drive member; and a stirring assembly disposed within the pot body, the drive member being drivably connected to a rotating base of the stirring assembly, the stirring assembly being the stirring assembly described above. Thus, the cooking device can also achieve two different degrees of rotation driven by a single drive member, ensuring simultaneous rotation of the bottom portion while achieving secondary three-dimensional stir-frying of the longitudinal side portions. The stir-frying of the side portions, while simultaneously rotating the bottom portion, is performed in a longitudinal, circular motion, resulting in a parabolic motion rather than a simple circular motion, thereby achieving true three-dimensional stir-frying.

[0027] Furthermore, the stirring assembly is detachably arranged in the pot body, which is convenient for cleaning the stirring assembly; the pot body includes a base and an inner pot arranged on the base, and the inner pot has a cooking cavity; the driving member includes a second driving motor arranged in the base, and the upper end of the second driving motor is provided with a motor shaft, and the driving motor is used to drive the rotating seat, which has the advantages of simple driving structure and low cost; an axle seat is fixedly provided at the bottom of the inner pot, and a transmission shaft is rotatably passed through the axle seat, the motor shaft is drivingly connected to the lower end of the transmission shaft, and the upper end of the transmission shaft is drivingly connected to the rotating seat, and the transmission shaft can be guided and limited by the axle seat so that the transmission shaft can only rotate around the axis of the axle seat, and the second driving motor drives the rotating seat to rotate through the transmission shaft; the cooking utensil also includes a cover body, which is openably and closably arranged on the pot body, and the cooking cavity of the pot body is sealed by the cover body.

[0059] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0060] like Figures 1 to 10 As shown, a first embodiment of the present invention provides a stirring assembly, which is disposed in a pot body 40. The stirring assembly includes a rotating base 10 and a stirring blade 20. The rotating base 10 is rotatably disposed in the pot body 40 around its vertical axis. The stirring blade 20 includes a horizontal shaft 21 and a stirring blade 22 disposed on the horizontal shaft 21. The horizontal shaft 21 passes through the side wall of the rotating base 10 and can rotate relative to the rotating base 10 around its axis. In the direction from top to bottom, the rotating base 10 rotates clockwise, and in the direction from the horizontal shaft 21 away from one end of the rotating base 10 to the direction close to the other end of the rotating base 10, the horizontal shaft 21 rotates counterclockwise; alternatively, in the direction from top to bottom, the rotating base 10 rotates counterclockwise, and in the direction from the horizontal shaft 21 away from one end of the rotating base 10 to the direction close to the other end of the rotating base 10, the horizontal shaft 21 rotates clockwise.

[0061] When the stirring assembly provided in this embodiment is used, when the rotating base 10 rotates, the rotating base 10 can drive the fixed blade 14 and the stirring blade 20 to revolve around the vertical axis of the rotating base 10. At this time, the fixed blade 14 and the stirring blade 22 of the stirring blade 20 can be used to stir the food in the cooking cavity in a circumferential direction, causing the food to move circumferentially within the cooking cavity (around the bottom wall and circumferential side walls of the cooking cavity). Furthermore, as the rotating base 10 rotates, the horizontal shaft 21 of the stirring blade 20 rotates about its axis relative to the rotating base 10. The horizontal shaft 21 drives the stirring blade 22 to rotate about its axis. The stirring blade 22 can then be used to vertically flip and stir the food in the cooking cavity, causing the food to be turned upside down. With the above structure, when the rotating base 10 rotates, the fixed blade 14 and the stirring knife 20 stir the food in the cooking cavity in the circumferential direction, so that the food moves along the circumferential direction of the cooking cavity. At the same time, the stirring knife 20 flips and stirs the food in the cooking cavity in the vertical direction, so that the food moves along the circumferential direction of the cooking cavity and flips along the vertical direction of the cooking cavity, thereby realizing three-dimensional stir-frying of the food in the cooking cavity, which can improve the stir-frying uniformity of the food and thereby improve the stirring effect of the stirring component on the food. Furthermore, since the rotation direction of the rotating base 10 is clockwise from top to bottom, the rotation direction of the horizontal shaft 21 is counterclockwise in the direction from one end of the rotating base 10 away from the rotating base 10 to the end close to the rotating base 10, and the rotation direction of the horizontal shaft 21 is counterclockwise from top to bottom, the rotation direction of the horizontal shaft 21 is clockwise in the direction from one end of the rotating base 10 away from the rotating base 10 to the end close to the rotating base 10. When the fixed blade 14 and the stirring knife 20 are used to flip the food circumferentially, since the rotation direction of the stirring knife 20 is opposite to the rotation direction of the rotating base 10 (clockwise / counterclockwise), the stirring knife 20 is easier to flip the food, the food flips more in the cooking chamber, the food is heated evenly, and the three-dimensional stirring effect of the stirring assembly on the food can be further enhanced.

[0062] It should be noted that three-dimensional stirring refers to the following: the fixed blades 14 and the stirring blade 20 stir the food in the cooking cavity circumferentially, while the stirring blade 20 flips and stirs the food in the cooking cavity vertically. This causes the food in the cooking cavity to flip both circumferentially and vertically, creating a three-dimensional flipping effect. In other words, while ensuring the circumferential rotation of the fixed blades 14 and the stirring blade 20, the stirring blade 20 achieves a secondary three-dimensional stir-frying in the longitudinal direction. The stir-frying in the side is achieved by a longitudinal circular motion that shifts as the base rotates. Therefore, the motion is parabolic, rather than a simple circular motion, thus achieving true three-dimensional stir-frying.

[0063] It should be noted that the direction from one end of the horizontal axis 21 away from the rotating base 10 to the end close to the rotating base 10 refers to Figure 4The left end of the horizontal axis 21 in the figure points to the right end.

[0064] In this embodiment, the rotating seat 10 is a cylindrical structure, which can provide a larger assembly space.

[0065] like Figure 6 、 Figure 9 as well as Figure 10 As shown, the stirring assembly further includes a fixed gear 31 and a movable gear 32. The fixed gear 31 has a horizontally arranged ring gear 311. The fixed gear 31 is locked in rotation with the pot body 40 or a cover provided on the pot body 40. The movable gear 32 is disposed on the horizontal shaft 21 and meshes with the ring gear 311. The meshing transmission method of the fixed gear 31 and movable gear 32 transmits the torque of the rotating base 10 to the horizontal shaft 21, and converts the vertical rotation of the rotating base 10 into the horizontal rotation of the horizontal shaft 21, so that the horizontal shaft 21 rotates horizontally while simultaneously following the circumferential revolution of the rotating base 10.

[0066] The fixed gear 31 and the pot body 40 or the cover body provided on the pot body 40 are in rotation-proof cooperation, which means that the fixed gear 31 and the pot body 40 are relatively fixed, or the fixed gear 31 and the cover body are relatively fixed.

[0067] In this embodiment, both the fixed gear 31 and the movable gear 32 are preferably bevel gears.

[0068] In this embodiment, the fixed gear 31 is engaged with the pot body 40 to prevent rotation, thereby securing the fixed gear 31 and the pot body 40 relative to each other. The movable gear 32 is vertically rotatably disposed within the rotating base 10. The movable gear 32 and the fixed gear 31 are engaged in a transmission manner, enabling the movable gear 32 to drive the stirring blade 22 to rotate via the horizontal shaft 21. Specifically, when the rotating base 10 rotates, because the horizontal shaft passes through the side wall of the rotating base 10, the rotating base 10 drives the horizontal shaft 21 and the stirring blade 22 to revolve. Simultaneously, the rotating base 10 drives the fixed blade 14 to revolve, enabling the fixed blade 14 and the stirring blade 22 to stir the food in a circumferential direction. Moreover, as the rotating base 10 rotates, the fixed gear 31 is fixed relative to the pot body 40 due to the anti-rotation cooperation between the fixed gear 31 and the pot body 40, and the movable gear 32 on the horizontal shaft 21 rotates around the ring gear 311 of the fixed gear 31. As the movable gear 32 rotates, the movable gear 32 drives the horizontal shaft 21 to rotate, thereby causing the stirring blade 22 on the horizontal shaft 21 to rotate with the horizontal shaft 21 and flip and stir the food vertically.

[0069] In this embodiment, the rotation axis of the fixed gear 31 is perpendicular to the rotation axis of the movable gear 32 , thereby converting the vertical rotation of the rotating base 10 into the horizontal rotation of the horizontal axis 21 .

[0070] The rotating base 10 has a downwardly extending mounting hole 15, within which both the fixed gear 31 and the movable gear 32 are located. The fixed gear 31 is locked against rotation by the pot body 40. The mounting hole 15 accommodates the fixed gear 31 and the movable gear 32, preventing them from being exposed, thereby enhancing the integrity of the stirring assembly.

[0071] like Figure 2 、 Figure 6 as well as Figure 9 As shown, the rotating base 10 has a downwardly extending vertical shaft 11. The driving member 41 of the pot body 40 is drivingly connected to the vertical shaft 11. The fixed gear 31 has a clearance hole 312 extending from top to bottom to pass through the vertical shaft 11. The ring gear 311 is disposed around the outer periphery of the clearance hole 312. By providing the clearance hole 312 and passing the vertical shaft 11 through the clearance hole 312, the driving connection between the driving member 41 and the rotating base 10 is achieved.

[0072] It should be noted that the rotating base 10 can be an integrated structure or a split structure. In this embodiment, the rotating base 10 is a split structure, comprising an upper base body and a lower base body, and the upper end of the vertical shaft 11 is connected to the upper base body.

[0073] Specifically, vertical shaft 11 is mounted on the top wall of the upper body. The upper body comprises a surrounding panel and a top plate connected to the upper end of the surrounding panel. Vertical shaft 11 is mounted on the top plate, and drive member 41 is drivingly connected to the upper body via vertical shaft 11. This structure eliminates the need for a large-diameter escape hole in the inner pot, resulting in a simple structure and ease of fabrication.

[0074] like Figure 6 and Figure 9 As shown, a shaft hole 13 is provided on the side wall of the rotating base 10. The rotating base 10 has a downwardly extending vertical shaft 11. The driving member 41 of the pot body 40 is drivingly connected to the vertical shaft 11. The vertical shaft 11 has a through hole 111 extending horizontally. The horizontal shaft 21 is inserted through the shaft hole 13 and through hole 111. With this structure, the horizontal shaft 21 can be assembled using the shaft hole 13 and through hole 111. The rotation of the vertical shaft 11 drives the horizontal shaft 21, which in turn rotates around the ring gear 311 via the driven gear 32, achieving circumferential stirring and vertical flipping of the food by the stirring blades.

[0075] Specifically, the movable gear 32 is disposed on the side of the vertical shaft 11 away from the stirring blade 22. This allows the movable gear 32 to rotate counterclockwise from the end of the rotating base 10 away from the rotating base 10 to the end of the rotating base 10 when the rotating base 10 rotates clockwise from top to bottom. Furthermore, the movable gear 32 rotates clockwise from the end of the rotating base 10 away from the rotating base 10 to the end of the rotating base 10 when the rotating base 10 rotates counterclockwise from top to bottom. This means that the self-rotation direction of the stirring blade 20 is opposite to the rotation direction of the rotating base 10 (clockwise / counterclockwise). Furthermore, the above structure can increase the torque transmitted by the movable gear 32, thereby improving the stirring performance.

[0076] like Figures 1 to 3 As shown, the fixed blades 14 are lower than the horizontal axis 21 and cooperate with the bottom wall of the cooking cavity 431 of the pot body 40. When the rotating base 10 rotates, the fixed blades 14 can stir the food that falls on the bottom wall of the pot body, thereby reducing the probability of food sticking to the bottom.

[0077] In the first embodiment, the lower end of the fixed gear 31 is fixedly connected to the pot body 40, and the rotating seat 10 is rotatably covered on the outer side of the fixed gear 31. The above structure has the advantage of being easy to process.

[0078] After extensive research, the inventors discovered that the uneven taste of food cooked in current automatic cooking appliances is due to the food often sticking to the inner wall of the pot (the cooking cavity wall) during cooking. The stirring blades used in related technologies cannot effectively solve this problem of food sticking to the pot, resulting in uneven heating of the food inside the pot, which in turn leads to an uneven taste of the cooked food, affecting the user experience. To improve the uniformity of the food's taste, the blade layout and structure of this application are as follows.

[0079] like Figure 3 As shown, in the first embodiment, the stirring blade 22 and the fixed blade 14 are respectively located on opposite sides of the rotating base 10. Specifically, the fixed blade 14 is arranged on the side wall of the rotating base 10 and is located at the bottom of the rotating base 10. When the rotating base 10 rotates, the fixed blade 14 can stir the food that falls on the bottom wall of the pot, thereby reducing the probability of the food getting stuck on the bottom. By arranging the stirring blade 22 on the side of the rotating base 10 away from the fixed blade 14, the stirring blade 22 has a sufficiently large rotation space. When the stirring blade 22 rotates, the stirring blade 22 and the fixed blade 14 will not interfere with each other, so that the stirring blade 22 can achieve a good vertical stir-frying effect.

[0080] like Figure 3 and Figure 4As shown, in embodiment one, the stirring blade 22 includes a first blade 221, and the first blade 221 includes a horizontal section 2211 and a bent section 2212 connected to each other, the horizontal section 2211 is connected to the horizontal axis 21, and the bent section 2212 cooperates with the side wall and bottom wall of the cooking cavity 431 of the pot body 40.

[0081] When the rotating base 10 rotates, the first blade 221 can follow the rotating base 10 and rotate around the circumferential direction of the pot body with the axis of the rotating base 10 as the axis (that is, the first blade 221 can revolve). At the same time, the first blade 221 can also rotate around the horizontal axis (that is, the first blade 221 can rotate on its own), thereby flipping the food. When the first blade 221 revolves, the bent section 2212 can cooperate with the side wall of the cooking cavity. At this time, the bent section 2212 can push the food adhered to the side wall of the cooking cavity to move. When the first blade 221 rotates on its own, the bent section 2212 can push the food adhered to the bottom wall of the cooking cavity and stir-fry the food, thereby reducing the probability of long-term contact between the food and the inner wall of the pot body, improving the uniformity of heating the food, and thus improving the uniformity of the taste of the food.

[0082] Specifically, in this embodiment, the bent section 2212 cooperates with the side and bottom walls of the cooking cavity. A portion of the bent section 2212 of the first blade 221 is positioned adjacent to the side walls of the cooking cavity, enabling it to push food against the side walls. Another portion of the bent section 2212 is positioned adjacent to the bottom wall of the cooking cavity, enabling it to push food against the bottom wall. Preferably, the curvature of the bent section 2212 matches the curvature of the side and bottom walls of the cooking cavity (inner pot), and the bottom cross-section of the bent section 2212 conforms to the shape of the pot, maintaining a distance of 0.5 mm to 1.5 mm from the pot.

[0083] In addition, it should be noted that the first blade 221 is not only capable of pushing the food stuck on the inner wall and bottom wall of the cooking cavity to move. Since the bent section 2212 has a certain width, when the stirring assembly is working, the first blade 221 can also stir-fry the food located in the middle of the cooking cavity, so that the food in the pot as a whole can be heated evenly.

[0084] Specifically, the bent section 2212 includes a first plate section 22121 connected to the horizontal section 2211 and a second plate section 22122 connected to the first plate section 22121. The first plate section 22121 extends vertically and engages with the side walls of the cooking cavity 431 of the pot body 40. The second plate section 22122 is spaced apart from the horizontal section 2211 and engages with the bottom wall of the cooking cavity 431 of the pot body 40. This structure facilitates the bent section 2212 to scrape food stuck to the inner wall and bottom wall of the cooking cavity and cause the food to flip, thereby reducing the probability of food being retained on the side walls or bottom wall of the cooking cavity and promoting a more uniform taste of the food.

[0085] In the first embodiment, the end of the second plate segment 22122 away from the first plate segment 22121 is offset relative to the horizontal segment 2211 in the circumferential direction of the rotating base 10. The above structure enables the second plate segment 22122 to contact the food first, the first plate segment 22121 to contact the food second, and the horizontal segment 2211 to contact the food last when the first blade 221 rotates. The above method can improve the smoothness of the rotation of the first blade 221. Reduce the probability of the first blade 221 being stuck by food. Specifically, if the horizontal segment 2211, the first plate segment 22121 and the second plate segment 22122 of the first blade 221 are in contact with food at the same time, the resistance of the first blade 221 during rotation will increase, causing the first blade 221 to be easily stuck by food.

[0086] In this embodiment, the first plate segment 22121 is a first arcuate segment, and the second plate segment 22122 is a second arcuate segment. In the above structure, the first plate segment 22121 is an arcuate curved structure along its extension direction. This structure, on the one hand, increases the contact area between the first plate segment 22121 and the food, increasing the probability of food being turned over and ensuring uniform heating of the food; on the other hand, it improves the smooth rotation of the first blade 221 and reduces the probability of the first blade 221 becoming stuck. Accordingly, the second plate segment 22122 is an arcuate curved structure along its extension direction, which also serves to ensure uniform heating of the food and improve the smooth rotation of the first blade 221.

[0087] In this embodiment, the width of the second plate segment 22122 gradually increases from closer to the first plate segment 22121 to farther away from the first plate segment 22121. In the above structure, if the second plate segment 22122 were configured with a uniform width, the production cost of the first blade 221 would increase. Food tends to fall toward the bottom of the pot under the influence of gravity. Therefore, the width of the second plate segment 22122 gradually increases from closer to the first plate segment 22121 to farther away from the first plate segment 22121. This increases the contact area between the second plate segment 22122 and the food in areas with high food density, thereby minimizing the production cost of the first blade 221 while ensuring the stirring effect of the first blade 221.

[0088] Accordingly, in this embodiment, the width of the first plate segment 22121 gradually increases from near the horizontal segment 2211 to away from the horizontal segment 2211. In the above structure, the first plate segment 22121 is wider in areas where the food density is higher, thereby increasing the contact area between the second plate segment 22122 and the food, further ensuring the stirring effect of the first blade 221 while minimizing the production cost of the first blade 221.

[0089] like Figure 3As shown, in the first embodiment, the stirring blade 22 further includes a second blade 222. The first blade 221 and the second blade 222 are located at the same end of the horizontal shaft 21, and the second blade 222 is spaced apart from the horizontal section 2211 in the circumferential direction of the horizontal shaft 21. In this structure, food adhered to the side walls and bottom wall of the cooking cavity can be turned over as the first blade 221 rotates, and food in the middle of the pot can also be turned over as the second blade 222 rotates. This further improves the uniformity of heating the food within the pot and ensures the food's taste.

[0090] like Figure 7 As shown, the distance between the axis of the horizontal shaft 21 and the bottom wall of the cooking cavity 431 of the pot body 40 is d, and the height of the cooking cavity 431 of the pot body 40 is h, where d ≤ h / 2. The above structure can maximize the size of the stirring blade 22, thereby improving the stirring effect.

[0091] It should be noted that in this embodiment, the stirring blades and fixed blades are coated with silicone to provide cushioning and prevent scratching of the inner pot. The fixed and movable gears are made of food-grade aluminum alloy, nylon 6 (PA6), polyformaldehyde (POM), or stainless steel.

[0092] In this embodiment, the ratio of the rotation speed of the rotating base 10 to the rotation speed of the horizontal shaft 21 is between 1:1 and 1:3. The stirring blades have a sufficiently high rotation speed, which can reduce the number of stirring blades 22 and improve the stir-frying effect.

[0093] Wherein, the ratio of the rotational speed of the rotating base 10 to the rotational speed of the horizontal shaft 21 can be 1:1, 1:1.5, 1:2, 1:2.5, 1:3. Alternatively, the ratio of the rotational speed of the rotating base 10 to the rotational speed of the horizontal shaft 21 is any other ratio between 1:1 and 1:3. In the present embodiment, the ratio of the rotational speed of the rotating base 10 to the rotational speed of the horizontal shaft 21 is preferably 1:3. By setting the ratio of the rotational speed of the rotating base 10 to the rotational speed of the horizontal shaft 21 within the above range, on the one hand, the stirring blade 22 will not be affected by its own structural strength due to excessively high rotational speed, and on the other hand, the rotation speed of the stirring blade 22 can meet the requirements of improving the stir-frying effect while simplifying the number of stirring blades 22. When the ratio of the rotational speed of the rotating base 10 to the rotational speed of the horizontal shaft 21 is 1:1, the structural strength of the stirring blade 22 itself is better. When the ratio of the rotational speed of the rotating base 10 to the rotational speed of the horizontal shaft 21 is 1:2, the stirring effect of the stirring blade 22 is better.

[0094] In this embodiment, the circumference L of the inner pot is taken as the horizontal coordinate, and the height H of the inner pot is taken as the vertical coordinate. The motion curve of the lowest point of the stirring blade 22 in the pot is as follows: Figure 20The ratio of the rotation speed of the rotating base 10 to the rotation speed of the horizontal shaft 21 will multiply the number of waveforms within the same circumference.

[0095] The movement state of the stirring component in the inner pot is as follows: Figures 21 to 23 shown.

[0096] It should be noted that, in this embodiment, the stirring assembly further includes a seal, which includes a first sealing portion and a second sealing portion. The first sealing portion is sealingly disposed between the outer wall of the fixed gear 31 and the inner wall of the rotating base 10, and the first sealing portion is utilized to seal the gap between the outer wall of the fixed gear 31 and the inner wall of the rotating base 10. The second sealing portion is sealingly disposed between the hole wall of the avoidance hole 312 and the side wall of the vertical shaft 11, and the second sealing portion is utilized to seal the gap between the hole wall of the avoidance hole 312 and the side wall of the vertical shaft 11. With the above structure, food in the cooking chamber will not enter the interior of the stirring assembly. This arrangement allows the complex gear transmission structure to be completely isolated from the outside world, which can improve the hygiene of the device and facilitate cleaning.

[0097] like Figures 11 to 19 As shown, the second embodiment of the present invention provides a stirring assembly. The difference between the second embodiment and the first embodiment lies in the different fixing method of the fixed gear 31 and the structure of the blades in the second embodiment.

[0098] like Figure 15 and Figure 16 As shown, in the second embodiment, the rotating base 10 has a downwardly extending mounting hole 15. A support boss 12 is provided on the inner sidewall of the rotating base 10. The fixed gear 31 is mounted on the support boss 12. The lower end of the fixed gear 31 protrudes downward from the support boss 12 and engages with the pot body 40 to prevent rotation. The support boss 12 provides support for the fixed gear 31, ensuring that the fixed gear 31 is assembled within the rotating base 10 and preventing the fixed gear 31 from falling.

[0099] like Figure 15 and Figure 16 As shown, the fixed gear 31 includes a shaft diameter section 315 and a flanged platform 313. The flanged platform 313 is provided at the upper end of the shaft diameter section 315, and the lower end of the shaft diameter section 315 is engaged with the pot body 40 for rotation prevention. The support boss 12 and the flanged platform 313 are both annular structures. The gear ring 311 is provided on the upper surface of the flanged platform 313, and the lower surface of the flanged platform 313 is mounted on the upper surface of the support boss 12. The fixed gear 31 is mounted on the support boss 12 via the flanged platform 313. Since both the support boss 12 and the flanged platform 313 are annular structures, the support area of ​​the fixed gear 31 can be increased, thereby improving the stability of the fixed gear 31 within the rotating base 10 during the rotation of the rotating base 10.

[0100] In the second embodiment, a rotation-stopping structure is provided between the fixed gear 31 and the pot body 40. The rotation-stopping structure comprises a rotation-stopping boss 44 and a rotation-stopping groove. The rotation-stopping boss 44 is provided on the shaft seat 412 of the pot body 40, and the rotation-stopping groove is provided on the fixed gear 31. The rotation-stopping boss 44 is inserted into the rotation-stopping groove. This structure, which prevents the fixed gear 31 from rotating with the shaft seat 412, has the advantages of a simple connection structure and easy assembly and disassembly.

[0101] In this embodiment, anti-rotation bosses 44 are provided on both symmetrical sides of the shaft seat 412, and anti-rotation grooves are provided on both symmetrical sides of the fixed gear 31. The two anti-rotation bosses and the two anti-rotation grooves are provided in a one-to-one correspondence.

[0102] like Figure 14 and Figure 16 As shown, at least two anti-rotation ribs 314 are provided on the outer wall of the fixed gear 31. The at least two anti-rotation ribs 314 are spaced apart along the circumference of the fixed gear 31. The anti-rotation ribs 314 extend from top to bottom, and the spaces between adjacent anti-rotation ribs 314 form anti-rotation grooves. The use of the spaces between the anti-rotation ribs 314 to form anti-rotation grooves has the advantages of simple structure and easy processing.

[0103] like Figure 13 As shown, in embodiment 2, the stirring blade 22 includes a third blade 223 and a fourth blade 224 connected to one end of the horizontal axis 21, and the third blade 223 and the fourth blade 224 are both arc-shaped structures, and the third blade 223 and the fourth blade 224 are centrally symmetrically arranged relative to the horizontal axis 21.

[0104] Since the third blade 223 and the fourth blade 224 are both curved, when the stirring assembly is in operation, the third blade 223 and the fourth blade 224 rotate to scoop up the food and then throw it back, causing the food to flip over, thereby stirring the food more thoroughly, more evenly, and more efficiently. Furthermore, the curved structure of the third blade 223 and the fourth blade 224 prevents the edges of the third blade 223 and the fourth blade 224 from making straight-line contact with the food, effectively preventing jamming during the stirring process.

[0105] Furthermore, because the stirring blade 22 includes both the third blade 223 and the fourth blade 224, the ingredients are stirred twice during each rotation of the stirring blade 22 as a whole, significantly improving stirring efficiency and ensuring more even heating and cooking of the ingredients. Furthermore, because the third blade 223 and the fourth blade 224 are centrally symmetrically arranged relative to the horizontal axis 21, the third blade 223 and the fourth blade 224 have the same stirring effect, ensuring that the ingredients are stirred with the same force and speed.

[0106] Therefore, through the above-mentioned setting, the stirring times are increased, the stirring efficiency is greatly improved, and the third blade 223 and the fourth blade 224 have the same stirring effect on the food, so that the stirring device stirs evenly and the user experience is good.

[0107] like Figure 13 As shown, in the second embodiment, the stirring blade 22 further includes a fifth blade 225 connected to the other end of the horizontal shaft 21. Due to the provision of the fifth blade 225, while ensuring a good stirring effect of the stirring assembly, the stirring efficiency is further improved.

[0108] Specifically, a fixed blade 14 is fixedly connected to the side wall of the rotating base 10 and is located directly below the fifth blade 225. Because the rotating base 10 is rotatably arranged about its vertical axis, the stirring blade 22 can simultaneously rotate and revolve around the rotating base 10, thereby achieving vertical stirring of the ingredients and a more uniform stirring effect. At the same time, the presence of the fixed blade 14, located below the fifth blade 225, improves stirring efficiency while achieving a more uniform stirring of the entire ingredients in the vertical direction, resulting in higher stirring efficiency.

[0109] A third embodiment of the present invention provides a stirring assembly. This embodiment differs from the first embodiment in that the stirring blade 20 is driven differently. In this embodiment, the stirring assembly further comprises a first drive motor disposed within the rotating base 10, the motor shaft of the first drive motor being drivably connected to the horizontal shaft 21. The use of the first drive motor offers the advantages of a simple structure and ease of installation.

[0110] like Figures 1 to 23 As shown, a fourth embodiment of the present invention provides a cooking utensil comprising a pot body 40 and a stirring assembly 50, wherein the pot body 40 has a driving member 41. The stirring assembly 50 is disposed within the pot body 40, and the driving member 41 is drivingly connected to the rotating base 10 of the stirring assembly 50. The stirring assembly 50 is the stirring assembly provided above. Therefore, the cooking utensil can also realize rotation at two different latitudes driven by a single driving member 41, ensuring that while the bottom rotates, a secondary three-dimensional stir-frying of the longitudinal side portions is achieved. The stir-frying of the side portions is achieved by a longitudinal circular motion that is displaced while the bottom rotates, so the motion is parabolic rather than simply circular, thus achieving true three-dimensional stir-frying.

[0111] In this embodiment, the stirring assembly 50 is detachably disposed in the pot body 40. With the above structure, the stirring assembly 50 is easy to clean.

[0112] Specifically, the pot body 40 includes a base 42 and an inner pot 43 disposed on the base 42 , and the inner pot 43 has a cooking cavity 431 .

[0113] like Figure 6 As shown, the driving member 41 includes a second driving motor 411 disposed in the base 42, and a motor shaft 4111 is disposed at the upper end of the second driving motor 411. Using the driving motor to drive the rotating base 10 has the advantages of simple driving structure and low cost.

[0114] A shaft seat 412 is fixedly mounted at the bottom of the inner pot 43. A drive shaft 413 is rotatably mounted within the shaft seat 412. A motor shaft 4111 is drivingly connected to the lower end of the drive shaft 413, while the upper end of the drive shaft 413 is drivingly connected to the rotating base 10. This structure guides and limits the drive shaft 413 via the shaft seat 412, ensuring that the drive shaft 413 can rotate only about the axis of the shaft seat 412. The second drive motor 411 drives the rotating base 10 via the drive shaft 413.

[0115] In this embodiment, the shaft seat 412 passes through the inner pot 43 and is fixedly connected to the inner pot 43 .

[0116] Specifically, the upper end of the transmission shaft 413 is drivingly connected to the vertical shaft 11 of the rotating base 10. The lower end of the vertical shaft 11 is provided with a rotation-stopping hole, and the upper end of the transmission shaft 413 is provided with a rotation-stopping surface. The upper end of the transmission shaft 413 is inserted into the rotation-stopping hole and engages with the vertical shaft 11 to prevent rotation. The rotation-stopping engagement between the rotation-stopping hole and the rotation-stopping surface enables the transmission shaft 413 to drive the vertical shaft 11 to rotate.

[0117] The cooking utensil further comprises a cover which is openably and closably arranged on the pot body 40. The cooking cavity 431 of the pot body 40 is sealed by the cover.

[0118] The cooking utensil includes an air fryer, an electric rice cooker, an electric pressure cooker, or a multifunctional heating pot with the functions of baking, cooking, and making dishes.
