Description

Technical Field

[0001] The present invention relates to the technical field of automated cooking equipment, and particularly to an automatic stir-frying device. Background Art

[0002] Stir-frying is the most commonly used and main method for making Chinese cuisine. Whether in restaurants, canteens or individual families, various stir-fried dishes are mostly served as main courses during regular meals. However, since ancient times, the stir-frying method in restaurants, canteens and individual families has still mainly been the traditional manual stir-frying method.

[0003] For manual stir-frying with a spatula, it seems very simple, but the on-site process requirements and the movement trajectory of the spatula vary greatly during stir-frying. When stir-frying manually, from the upper arm, forearm to the wrist, the three joints of the human body can achieve a six-degree-of-freedom movement space. Therefore, when manually operating the spatula in the frying pan, it can achieve a 360° arbitrary trajectory movement to complete various stir-frying actions. However, replacing this execution process with an automated mechanical device is very complex. Although the current level of robot technology can achieve the stir-frying function of this spatula, due to the overall large volume and weight of the robot, too many supporting devices, too high cost, and complex operation and control, it is not suitable for application in individual families and small and medium-sized restaurant canteens.

[0004] In the existing household automatic stir-frying machines, the spatula only has a one-degree-of-freedom rotation stir-frying mode in a two-dimensional plane, so the stir-frying effect is not ideal, and the types of stir-fried dishes applicable are also very few. Some large institutional restaurants and canteens generally use drum-type automatic stir-frying machines. Although stir-frying with a drum flip adds one degree of freedom compared to stir-frying with an automatic spatula and the stir-frying efficiency is improved to some extent, the disturbance to the dishes is too large, and it is only suitable for making a few common large-portion dishes. Moreover, this type of automatic drum stir-frying machine has a large volume and weight, high cost, and complex operation and control, and is not suitable for the personalized stir-frying needs of individual families and small and medium-sized restaurant canteens with a variety of small-portion dishes, low cost, simple operation and control requirements, and a small operation space. Summary of the Invention

[0024] The technical solution of the present invention has the following advantages:

[0025] 1. For the automatic stir-fry device provided by the present invention, the flat spatula is the most commonly used spatula during automatic stir-frying. In order to freely rotate closely against the inner side of the stir-fry pot in both the horizontal and vertical directions, the front end part along its movement direction is designed as a curved surface that fits the inner side wall of the stir-fry pot, which improves the effective contact area and the vegetable shoveling ability of the front edge of the flat spatula. The rear end of the flat spatula gradually tilts away from the inner side wall of the stir-fry pot. When the flat spatula rotates horizontally to shovel vegetables, since the middle and rear parts of the flat spatula are gradually tilted, and the surface of the flat spatula is lower on the inner side and higher on the outer side, the vegetable materials shoveled up gradually rise when passing through the rear end of the flat spatula, and then tumble down after passing through the flat spatula, forming a small stir-frying effect. The vertical spatula is an auxiliary spatula used in cooperation with the flat spatula and is arranged at an angle with the inner side wall of the stir-fry pot. During operation, the rotation driving mechanism can drive the rotating turntable to continuously rotate or intermittently rotate within the installation space in the horizontal direction, thereby driving the spatula mechanism to continuously rotate or intermittently rotate in the horizontal direction; at the same time, the flipping driving mechanism can drive the spatula mechanism to flip or swing in the vertical plane. So that the vertical spatulas and flat spatulas at both ends of the spatula mechanism can rotate horizontally in the inner cavity of the stir-fry pot, and can also flip or swing vertically. The dishes in the stir-fry pot can be arbitrarily stir-fried in multiple directions of front, back, left, right, up and down under the shoveling of the vertical spatulas and flat spatulas. According to different dishes, different stir-frying processes and different stir-frying stages, by adjusting the spatula selection, rotation timing, rotation mode, rotation direction, rotation speed, rotation frequency and rotation amplitude of the rotation driving mechanism and the flipping driving mechanism, different degrees of stir-frying or flat-frying can be carried out, so that the automatic stir-fry device can automatically make the vast majority of stir-fried dishes.

[0026] 2. The automatic cooking device provided by the present invention has a spatula width at the front end of the flat spatula part no less than that at the rear end, reducing the area of residual vegetables or adhered vegetable leaves at the tail of the flat spatula part, making the vegetables scooped up by the flat spatula part fall off faster and more easily. A comb tooth part is provided at the rear end of the flat spatula part, and combing gaps are arranged at intervals on the comb tooth part. This is to accelerate the dropping of the vegetable juice and vegetables on the flat spatula part and reduce the residual adhesion of vegetable leaves and vegetable residues at the tail of the flat spatula part when the flat spatula part rotates vertically for frying. In addition, when frying some thin strip or filament-like vegetables or cooking noodles for soup noodles, the combing gaps of the wide tooth-like structure at the tail can also play a certain combing role.

[0027] 3. The automatic cooking device provided by the present invention, the scraping plate part includes a main scraping plate area and a secondary scraping plate area. The main scraping plate area is inclined towards the direction away from the inner wall of the cooking pot, and the secondary scraping plate area is arranged in close fit with the inner side wall of the cooking pot. The main scraping plate area is used to level and flatten the vegetables, and the secondary scraping plate area is further tilted upwards on the basis of the inclination of the main scraping plate area and closely adheres to the inner side wall of the cooking pot. Its main function is to scrape off a small amount of vegetables adhered to the inner wall of the cooking pot and guide and gather them to the middle of the cooking pot.

[0028] 4. The automatic cooking device provided by the present invention, the scraping plate part is rotatably installed at the end of the connecting support rod, the scraping plate part is slidably matched with the connecting support rod, and an elastic reset part is installed between the scraping plate part and the connecting support rod. According to the quantity and different types of vegetables in the cooking pot, by adjusting the rotation angle of the scraping plate part in the vertical direction, the most suitable height working position of the main scraping plate area can be determined. For relatively fluffy leafy vegetables, the downward pressure of the scraping plate part can be appropriately increased.

[0029] 5. The automatic cooking device provided by the present invention, the frying spatula mechanism includes a connecting rod, the flat spatula part and the vertical spatula part are respectively installed at both ends of the connecting rod, the flat spatula part and the vertical spatula part are both slidably matched with the connecting rod, and elastic reset parts are installed between the flat spatula part and the vertical spatula part and the connecting rod. Under the action of the elastic reset parts, the flat spatula part and the vertical spatula part have the function of elastic stretching and contracting in the axial direction of the connecting rod, making the flat spatula part and the vertical spatula part fit more closely with the inner side of the cooking pot when shoveling vegetables. The flat spatula part and the vertical spatula part are increased with the function of automatically slightly stretching and contracting in the vertical direction by relying on the elastic force. Relying on this elastic compression function, when the flat spatula part and the vertical spatula part rotate in the cooking pot, they can be compressed and closely adhere to the inner side of the cooking pot, so as to improve the ability of the flat spatula part and the vertical spatula part to closely adhere to the bottom and the side of the cooking pot when shoveling vegetables.

[0030] 6. The automatic cooking device provided by the present invention has a hemispherical inner cavity of the cooking pot, and the shovel mechanism's rotation radius is smaller than the pot's inner diameter. This increases the shovel mechanism's flexibility and freedom of movement within the pot, reducing the shovel mechanism's ineffective working area within the pot. Furthermore, the reduced rotation radius of the shovel mechanism also reduces the shovel mechanism's rotation torque, lowering the vertical rotation height of the shovel mechanism, thereby reducing the output power requirement and power consumption of the rotation drive mechanism and reducing the height space within the cooking machine. Furthermore, by positioning the intersection of the extended line of the rotation drive mechanism's output shaft and the vertical centerline of the cooking pot's inner cavity below the pot's spherical center, a certain amount of compression space is created between the shovel mechanism and the pot's bottom, enhancing the shovel mechanism's ability to cling tightly to the pot's bottom and sides. Because the shovel mechanism has an elastic expansion function, the vertical rotation height of the shovel mechanism can also be reduced, further reducing the height space within the cooking machine.

[0031] 7. In the automatic cooking device provided by the present invention, the centerline of the vertical rotation axis of the shovel mechanism is tilted upward along the horizontal direction. Specifically, the output axis of the tilting drive mechanism forms a predetermined angle with the horizontal direction. This creates an inclination angle for the flat and vertical shovel members of the shovel mechanism as they tilt into the cooking pot. This increases the effective travel and working area of the flat and vertical shovel members from the top to the bottom of the cooking pot. Combined with the horizontal rotation of the flat and vertical shovel members, this achieves a cooking effect closer to that of manual cooking. Furthermore, compared to a non-tilted design, the maximum vertical rotation radius of the flat and vertical shovel members within the cooking pot can be significantly reduced, while maintaining the required structural space for the tilting drive mechanism on the upper outer side of the cooking pot. This significantly reduces the maximum torque of the shovel mechanism during shoveling, thereby reducing the output power requirement and power consumption of the tilting drive mechanism. Furthermore, it further reduces the height and weight of the cooking machine itself.

[0032] 8. In the automatic cooking device provided by the present invention, the vertical rotation axis of the connecting rod is parallel to, but not colinear with, the vertical centerline of the cooking pot. This results in a horizontally offset design of the overall shovel mechanism. This allows the shovel mechanism to be closer to the upper edge of the pot's inner wall when entering the cooking pot, allowing it to quickly scoop into the bottom of the ingredients at the top of the pot, preventing small amounts of scattered ingredients from being scooped up. The shovel mechanism is also positioned away from the pot's edge and closer to the center when leaving the pot's bottom exit point. This allows any ingredients and juices that fall from the pot when the shovel mechanism flips upward to flip the food to fall as close to the center as possible, thereby reducing the problem of food sticking to the pot. This also increases the elastic compression space of the shovel mechanism during the first half of its entry into the cooking pot, further improving the shovel mechanism's ability to scoop food against the pot's edge and the cooking effect.

[0033] 9. The automatic cooking device provided by the present invention further includes cleaning bumps. By using the compression function when the flat spatula and the vertical spatula on the spatula mechanism pass through the bumps and the blocking and rebounding function that they cannot rotate back after passing through the bumps, the flat spatula and the vertical spatula can be vibrated twice when flipping in the vertical direction. The vegetable leaves, vegetable residues, and vegetable juices adhering and remaining on the spatula mechanism can fall back into the cooking pot when the flat spatula or the vertical spatula rebounds and collides.

[0034] 10. The automatic cooking device provided by the present invention further includes a temperature sensor and a cooking monitoring component. Through the temperature sensor and the cooking monitoring component, the temperature and video image information in the cooking pot can be obtained in real time. According to the frying process requirements of different dishes and the taste preferences of diners, the spatula selection, rotation timing, rotation mode, rotation direction, rotation speed, rotation time, rotation frequency, and rotation amplitude of the spatula mechanism can be intelligently and automatically controlled, so that different cooking actions can be performed for different dishes and different cooking stages, enabling the automatic cooking device to automatically make the vast majority of stir-fried dishes.

[0058] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0059] Figures 1 to 18The present embodiment shows an automatic cooking device, which is a mechatronic terminal device capable of completing various food processing and production functions, including fully automatic cooking, fully automatic loading, automatic water sprinkling and draining, automatic exhaust, automatic egg beating and sauce stirring, automatic juice making, and heat preservation and heating of rice.

[0060] The automatic cooking device provided in this embodiment mainly includes eight functional areas: automatic cooking area, automatic loading area, automatic water sprinkling and draining area, oil fume purification and emission filtration area, heat preservation and hot rice area, automatic exhaust area, automatic stirring area, and automatic juice making area.

[0061] The following description focuses primarily on the automatic cooking area. The automatic cooking device comprises a cooking machine body, a cooking pot 1, a rotary drive mechanism 2, and a shovel mechanism. The cooking machine body includes an installation cavity, with mounting spaces circumferentially arranged on the sidewalls. The cooking pot 1 is removably mounted at the bottom of the cavity. The rotary drive mechanism 2 is fixedly connected to the cooking machine body. A rotating turntable 3 is mounted on the output end of the rotary drive mechanism 2. The rotating turntable 3 is rotatably mounted within the mounting space. The rotary drive mechanism 2 is adapted to drive the rotating turntable 3 to rotate horizontally within the mounting space. A flip drive mechanism 4 is fixedly mounted on the rotating turntable 3, with the output shaft of the flip drive mechanism 4 facing the cooking pot 1. The shovel mechanism is removably mounted on the flip drive mechanism 4. A flat shovel member 6 is mounted on one end of the shovel mechanism, and a vertical shovel member 7 is mounted on the other end. The flip drive mechanism 4 is adapted to drive the shovel mechanism to flip around the output shaft of the flip drive mechanism 4. In this embodiment, the driving ends of the rotation drive mechanism 2 and the flip drive mechanism 4 are respectively connected to the output ends of the drive motors, and the drive motors are respectively electrically connected to the control device. The output end of the rotation drive mechanism 2 is driven by the rotating turntable 3 through gears.

[0062] The vertical shovel member 7 is angled relative to the inner wall of the wok 1. The front end of the flat shovel member 6, along its direction of motion, is positioned in contact with the inner wall of the wok 1, while the rear end of the flat shovel member 6 gradually tilts away from the inner wall of the wok 1. The shovel member 6 has a shovel width at its front end that is no less than the width at its rear end. The rear end of the flat shovel member 6 is provided with comb teeth, which are spaced apart by combing slits.

[0063] The frying shovel mechanism also features a connecting rod 8, which serves as an auxiliary link. The line connecting the flat shovel member 6 and the vertical shovel member 7 is perpendicular to the connecting rod 8. A scraper member 9 is mounted on the end of the connecting rod 8. The scraper member 9 comprises a primary scraper section and a secondary scraper section. The primary scraper section is tilted away from the inner wall of the wok 1, while the secondary scraper section is positioned to closely contact the inner wall of the wok 1. In this embodiment, the scraper member 9 is slidably mounted on the end of the connecting rod 8, and a spring is installed between the scraper member 9 and the connecting rod 8 as an elastic return member.

[0064] The frying spatula mechanism includes a connecting rod 5. A flat spatula member 6 and a vertical spatula member 7 are respectively installed at both ends of the connecting rod 5. The flat spatula member 6 and the vertical spatula member 7 are both slidably engaged with the connecting rod 5, and springs serving as elastic reset members are installed between the flat spatula member 6 and the vertical spatula member 7 and the connecting rod 5. A connecting support rod 8 is vertically arranged with respect to the connecting rod 5 and the connecting support rod 8 is fixedly connected to the middle position of the connecting rod 5.

[0065] The inner cavity of the frying pan 1 is hemispherical. The flipping radius of the frying spatula mechanism is smaller than the inner diameter of the frying pan 1, and the extension line of the output shaft of the flipping drive mechanism 4 intersects with the vertical center line of the inner cavity of the frying pan 1 at a point lower than the center of the sphere of the frying pan 1. The vertical rotation axis of the connecting rod 5 is parallel to the vertical center line of the frying pan 1 and they are not collinear. On the side where the frying spatula mechanism vertically flips and rises at the lower part of the inner cavity of the cooking machine body, a cleaning bump 10 is fixedly installed, and the frying spatula mechanism is adapted to be in extrusion and / or collision cooperation with the cleaning bump 10.

[0066] The frying spatula mechanism in the automatic cooking device provided in this embodiment is a multifunctional replaceable frying spatula combination mechanism of three frying tools: a flat spatula member 6, a vertical spatula member 7, and a scraping plate member 9. Since in the full-automatic cooking process of this solution, for different cooking procedures, technological requirements, and different food ingredients and seasonings, corresponding different frying spatula tools are used, it can well meet the needs of the vast majority of cooking varieties and cooking processes, and the cooking efficiency and cooking effect are also greatly improved. For other dishes or special dishes that cannot be satisfied by this set of combined frying spatula mechanisms, other special-purpose frying spatula mechanisms with various different shapes and cooking functions can also be replaced according to actual needs. The frying spatula mechanism provided in this embodiment also conducts a series of special structural designs on the three frying tools of the flat spatula member 6, the vertical spatula member 7, and the scraping plate member 9.

[0067] The flat shovel 6 is the most commonly used shovel tool for automatic cooking. To ensure free rotation both horizontally and vertically against the inside of the wok, the front end of the shovel 6 is designed as a spherical curved surface that conforms to the inner wall of the wok 1. The front end of the shovel 6 is approximately 100 mm wide and 40 mm long. The front 10 mm or so of the shovel 6 maintains a uniform curvature with the inner wall of the wok 1, ensuring close contact. This increases the effective contact area and shoveling capacity of the front end of the shovel 6. The shovel 6 gradually rises toward the rear at its center, reaching a maximum elevation of approximately 20 mm at the rear. When the shovel 6 rotates horizontally, the gradually rising middle and rear ends of the shovel 6, along with the lower inner edge and higher outer edge of the shovel 6, cause the scooped food to gradually rise as it passes the rear end of the shovel 6, tumbling and falling after passing through the shovel 6, creating a subtle stir-frying effect. In this way, when the vertical rotation stir-fry function is not in use, the horizontal rotation alone can achieve the desired stir-fry effect for some dishes or smaller quantities. Furthermore, the tilted tail of the shovel 6 prevents it from shoveling ingredients when it swings back to the tail end during the horizontal rotation and swing stir-fry mode. Even if it encounters some ingredients, the tilted tail of the shovel 6 contacts the ingredients through the arc-shaped inclined vertical surface, preventing the ingredients from being picked up. The rear end of the shovel 6 is approximately 70 mm wide, 30 mm less than the front end. This reduces the area of residual ingredients or leaves stuck to the tail end of the shovel 6, allowing the ingredients scooped up by the shovel 6 to fall off more quickly and easily. The comb teeth at the tail end of the shovel 6 are designed with wide teeth, which accelerates the shedding of leaves, juice, and residue from the shovel 6 when the shovel 6 is flipped vertically for stir-frying, preventing or reducing the amount of leaves and residue stuck to the tail end of the shovel 6. In addition, the wide-toothed comb structure at the tail can also play a certain combing role when stir-frying some thin strips or filaments of vegetables or cooking noodles to make soup.

[0068] The vertical spatula part 7 is an auxiliary spatula used in conjunction with the flat spatula part 6. Its overall shape is similar to that of a vertical knife, with a height of approximately 15 mm. In the initial stage of stir-frying, through the combination of rotating in the horizontal direction and repeatedly swinging in the vertical direction, the vertical spatula part 7 can be used for processes such as lubricating the stir-frying pan with oil, stir-frying scallions, ginger, garlic, chili peppers, Chinese prickly ash, etc., stir-frying meat, and stir-frying various seasonings. Since these processes generally do not involve flipping, but mainly involve repeatedly scraping and stir-frying, using the vertical spatula part 7 for stir-frying is more convenient and simpler to control than using the flat spatula part 6, and the effect is also better. For some small leafy vegetables or when the amount of stir-fried vegetables is very small, during the stir-frying process, because the vegetable materials are small, light, and slippery or the quantity is small, it is very difficult to use the flat spatula part 6 for flipping. Stir-frying does not require continuous flipping all the time, and only requires repeated scraping and stir-frying or continuous horizontal rotation plus repeated swinging for stir-frying. At this time, using the vertical spatula part 7 for stir-frying is very convenient and efficient, and it is not easy to stick to the vegetable leaves or leave vegetable residues when using the vertical spatula part 7 for stir-frying. In addition, in the later stage of stir-frying, it is often necessary to adjust the sauce and thicken it. At this time, it is necessary to scrape and pull out some empty spaces in the inner cavity of the stir-frying pan 1 for preparing the thickening sauce. At this time, the vertical spatula part 7 can be used to repeatedly swing and scrape at the corresponding position of the feeding port in the middle area of the stir-frying pan 1, so as to scrape out an empty space and perform the processes of preparing, mixing, and cooking the thickening sauce at this place.

[0069] The vertical spatula part 7 can also be used for the automatic production of foods such as porridge, soup, and noodle soup. When boiling various porridge foods or making foods such as soup and noodle soup, it is necessary to constantly stir and scrape the bottom of the pot manually to promote the uniform fusion of the food materials and water, accelerate the cooking of the food materials, and prevent the bottom of the pot from sticking or burning. At this time, using the automatic swinging function and the automatic horizontal rotation function of the vertical spatula part 7 can replace the laborious and time-consuming continuous stirring operation of manual labor. At the same time, the automatic feeding mechanism can be used to complete the automatic feeding and discharging of different main ingredients, ingredients, or seasonings, so as to easily realize the full-automatic processing and production function of these types of non-stir-fried foods with relatively high daily demand.

[0070] The scraper 9 is also an auxiliary tool that is often needed during the cooking process. Generally, after the flat shovel 6 stirs the food once, the food in the cooking pot 1 is often messy, scattered around, and unevenly distributed, which is not conducive to the uniform heating of the food and the flavoring of the seasoning. Because it is difficult to complete this cooking function by relying on the flat shovel 6 and the vertical shovel 7, a special tool called the scraper 9 is specially provided. The working surface of the scraper 9 is divided into two parts according to its function: a main scraper area close to the middle part of the cooking pot 1 and a secondary scraper area close to the edge of the inner wall of the cooking pot 1. The main scraper area is a rectangular flat arc-shaped thin plate. The horizontal length of the center point of the scraper 9 root is about 110mm, and the longitudinal width of the inclined surface is about 50mm. The working position of the main scraper area is high in front and low in the back, and is inclined at an angle of about 50°. The main scraper area is mainly used to smooth and flatten the food. The outer secondary scraper section of scraper 9 is further tilted and raised, building upon the tilt of the primary scraper section. Its outer shape matches and closely matches the inner and upper edges of the wok. Its primary function is to scrape off small amounts of food adhering to the upper edges of wok 1 and gather them in the center of the wok. After the flat shovel member 6 completes a round of stir-frying, scraper 9 automatically rotates vertically to its working position. At this point, the outermost tilted and raised portion of scraper 9 closely aligns with the middle and upper edges of the wok's inner wall. As scraper 9 rotates horizontally, it scrapes off any vegetable leaves or debris adhering to the edges of wok 1 and gathers them inside. The central, tilted, flat, curved portion of scraper 9 rests against the upper layer of food within the wok. As scraper 9 rotates horizontally, it smooths or flattens any unevenly distributed food within the wok, ensuring even heating. According to the quantity and different types of the vegetables in the cooking pot, the angle of the vertical rotation of the regulation scraper member 9 just can determine the most suitable high and low working position of the main scraper district. To more fluffy leafy vegetables, the downward pressure of the scraper member 9 can suitably increase some.

[0071] The coordination between the shovel mechanism and the wok 1 provided in this embodiment also incorporates a series of unique structural designs. Within the wok 1, on the vertical centerline from the spherical center to the center of the wok bottom, the shovel mechanism's vertical rotation radius is 8 mm smaller than the spherical radius within the wok 1. Because the amount of ingredients in the wok 1 typically does not exceed two-thirds of its full capacity, this design increases the shovel mechanism's flexibility within the wok 1 and reduces its ineffective working area within the wok 1. Furthermore, the reduced rotation radius also reduces the mechanism's rotational torque and the height of its vertical flipping motion. This reduces the output power requirement and energy consumption of the flip drive mechanism 4 that drives the flipping motion, and also reduces the height space within the wok.

[0072] Meanwhile, on the vertical center line of the inner cavity of the cooking pan 1, the center point of the vertical rotation axis of the spatula mechanism, which is the extension line of the output shaft of the flipping drive mechanism 4 intersecting with the vertical center line of the inner cavity of the cooking pan 1, is offset downward by 10 mm from the center point of the sphere inside the cooking pan 1. Since the vertical rotation radius of the spatula mechanism is 8 mm smaller than the spherical radius inside the cooking pan 1, the flipping radius of the spatula at the center point of the vertical rotation axis is actually 2 mm larger than the spherical radius inside the cooking pan 1. Such a design is mainly to increase a certain compression space between the spatula mechanism and the bottom of the cooking pan 1, so as to enhance the ability of the spatula mechanism to closely adhere to the bottom and the side of the pan for vegetable shoveling, because both the spatula handles of the flat spatula 6 and the vertical spatula 7 in the spatula mechanism have elastic telescopic functions. At the same time, such a design can also reduce the height of the vertical flipping of the spatula mechanism, and further reduce the height space of the inner cavity of the cooking machine.

[0073] The center line of the vertical rotation axis of the spatula mechanism is inclined upward at an angle of 16° in the horizontal direction, that is, the output shaft of the flipping drive mechanism 4 forms an angle of 16° with the horizontal direction. This makes the flat spatula 6 and the vertical spatula 7 on the spatula mechanism have an inclined angle when flipping into the cooking pan 1, thereby increasing the effective stroke and effective working area of the flat spatula 6 and the vertical spatula 7 from the upper side to the bottom of the cooking pan 1. Coupled with the horizontal rotation of the flat spatula 6 and the vertical spatula 7, the cooking effect of the flat spatula 6 and the vertical spatula 7 is closer to the manual cooking mode. At the same time, compared with the non-inclined design, when the maximum rotation radius of the flat spatula 6 and the vertical spatula 7 in the vertical direction inside the cooking pan 1, under the same condition of the necessary structural space of the flipping drive mechanism 4 on the upper side of the outer edge of the cooking pan 1, it can be reduced by about 36 mm. This greatly reduces the maximum torque when the spatula mechanism shovels vegetables, and thus reduces the output power requirement and power consumption of the flipping drive mechanism 4, and further reduces the height space of the inner cavity of the cooking machine.

[0074] The center line of the vertical rotation axis in the spatula mechanism is offset 5 mm to the right in the horizontal direction from the vertical center line of the sphere inside the cooking pan 1. This lateral eccentric design enables the flat spatula 6 and the vertical spatula 7 to be closer to the upper edge of the inner wall of the pan when entering the cooking pan 1, so as to quickly shovel under the bottom of the vegetable materials on the upper side of the pan and avoid the situation that a small amount of scattered vegetable materials on the upper side of the pan cannot be shoveled. It also enables the flat spatula 6 and the vertical spatula 7 to be farther from the pan edge and closer to the middle at the out-of-the-pan point when leaving the bottom of the pan, so that the vegetable materials, vegetable juice, etc. falling when the flat spatula 6 and the vertical spatula 7 are flipped upward can fall as much as possible to the middle position inside the pan, thereby reducing the problem of vegetable piling and sticking to the pan edge. At the same time, it can also increase the elastic compression space when the flat spatula 6 and the vertical spatula 7 shovel vegetables in the first half of the process of entering the cooking pan 1, thereby further improving the vegetable shoveling ability and cooking effect of the flat spatula 6 and the vertical spatula 7 closely adhering to the pan edge.

[0075] In addition, by increasing the elastic telescopic function of the spatula handles of the flat spatula 6 and the vertical spatula 7 in the vertical direction, the flat spatula 6 and the vertical spatula 7 can fit more closely to the inner edge of the frying pan 1 when shoveling vegetables. The spatula handles of the flat spatula 6 and the vertical spatula 7 are added with a function of automatically and slightly telescoping in the vertical direction by relying on elasticity, and the maximum telescopic amount is 4 mm. In order to limit the telescopic amount of the flat spatula 6 and the vertical spatula 7, waist-shaped limiting holes are provided on the spatula handles of the flat spatula 6 and the vertical spatula 7, and limiting posts are provided in the inner cavities at both ends of the connecting rod 5. The spatula handle slides on the limiting posts, thereby limiting the telescopic amount of the flat spatula 6 and the vertical spatula 7. Relying on this elastic compression, in the first half of the flipping movement of the flat spatula 6 and the vertical spatula 7 in the frying pan 1, they can be closely attached to the inner edge of the frying pan 1 due to being compressed, so that the ability of the flat spatula 6 and the vertical spatula 7 to closely attach to the bottom and the edge of the pan to shovel vegetables can be improved.

[0076] Through this series of special and ingenious structural designs, the flat spatula 6 and the vertical spatula 7 can enter the frying pan 1 more smoothly when flipping in the vertical direction, have a greater flexibility degree of flipping after entering the frying pan 1, and have a better effect of shoveling vegetables closely along the edge of the pan. At the same time, because the flat spatula 6 and the vertical spatula 7 rotate into the frying pan 1 at an inclined angle, the effective stroke and effective working area of the flat spatula 6 and the vertical spatula 7 in the frying pan 1 are larger, and the actions and effects of the flat spatula 6 and the vertical spatula 7 in stir-frying are closer to the manual stir-frying mode. In addition, this design not only greatly improves the efficiency and effect of automatic stir-frying of the flat spatula 6 and the vertical spatula 7, but also greatly reduces the height of the inner cavity of the stir-frying machine, thereby greatly reducing the overall height of the automatic stir-frying device and also reducing the overall weight of the automatic stir-frying device.

[0077] The spatula mechanism provided in this embodiment can not only automatically rotate horizontally, but also automatically flip or swing repeatedly in the vertical direction, so as to realize the rotational movement of the flat spatula 6 and the vertical spatula 7 in any direction in the 360° three-dimensional space. By selecting three spatulas with different functions and continuously adjusting the combination mode, rotation timing, rotation speed, rotation direction, rotation time, rotation frequency, rotation amplitude, etc. of the horizontal rotation and vertical flipping of the spatula mechanism at any time, various complex continuous or intermittent automatic stir-frying functions can be realized. With relatively simple mechanical structures and control methods, various complex and changeable stir-frying actions similar to traditional manual stir-frying are realized, better meeting the various needs of different spatulas and different spatula actions for various processes, techniques and food materials in automatic stir-frying, so that the automatic stir-frying device can realize the full-automatic stir-frying function for the vast majority of home-cooked dishes and popular Chinese cuisine dishes.

[0078] The horizontal rotation control mechanism of the frying spatula mechanism is driven by a driving motor of the rotation driving mechanism 2 to drive a gear transmission mechanism, which drives a circular rotating turntable 3 to rotate. The rotating turntable 3 is fixedly connected to the driven gear of the gear transmission mechanism to form an integral structure. The rotating turntable 3 is fixedly supported and rotated by a tapered roller bearing below and a ball bearing above. The rotating turntable 3 adopts a circular hollow structure, and a vertical flipping driving mechanism 4 directly driven by a driving motor is additionally installed on the rotating turntable 3, so that the torques of the frying spatula mechanism in the horizontal and vertical directions of the rotating shaft do not need to be too large, and the requirements for the output power of the driving motor are not high. Therefore, the space occupied by the motor can be saved and energy can be saved and consumption reduced. Moreover, due to the overall simple and compact structure, easy to control, small volume and low cost, it is very suitable for personal families and small and medium-sized restaurant canteens. The power supply of the driving motor of the flipping driving mechanism 4 is completed by a slip ring electrical connector. In order to increase the length and strength of the output shaft of the flipping driving mechanism 4 to facilitate the loading and unloading of the frying spatula mechanism and improve the installation firmness and heat insulation protection effect of the frying spatula mechanism, a lengthened, thickened and heat-insulated shaft sleeve structure is installed on the output shaft of the flipping driving mechanism 4.

[0079] In the automatic frying area, the frying spatula mechanism can achieve a variety of automatic frying modes under the combined drive of the rotation driving mechanism 2 and the flipping driving mechanism 4. There are mainly the following several kinds: First, the vertical spatula 7 only rotates automatically in the horizontal direction at the working position; Second, the vertical spatula 7 rotates automatically in the horizontal direction and swings in the vertical direction at the working position; Third, the flat spatula 6 only rotates automatically in the horizontal direction at the working position; Fourth, the flat spatula 6 rotates automatically in the horizontal direction and flips automatically in the vertical direction at the working position. In this mode, there are four forms: continuous rotation in the horizontal direction plus continuous flipping in the vertical direction, continuous rotation in the horizontal direction plus repeated swinging in the vertical direction, intermittent rotation in the horizontal direction plus continuous flipping in the vertical direction, and intermittent rotation in the horizontal direction plus repeated swinging in the vertical direction. All of these four forms are used in automatic frying, but the most commonly used is the automatic stir-frying mode of intermittent rotation in the horizontal direction plus repeated swinging in the vertical direction. This mode can well complete various stir-frying actions in the automatic frying process of most dishes, and the action form and movement trajectory of the frying spatula in this mode are also most similar to the traditional manual frying mode; Fifth, the scraping plate 9 rotates automatically in the horizontal direction when at the working position. This is the only working mode of the scraping plate 9. The rotation of the scraping plate 9 in the vertical direction is mainly to adjust the height of the contact between the scraping plate 9 and the ingredients, so as to control the height and strength of the scraping and flattening of the ingredients by the scraping plate 9.

[0080] In addition, a dual light-wave heating lamp auxiliary heating function is added to both sides of the top of the inner cavity of the cooking machine in the automatic cooking area. When cooking a large amount of dishes or when high heat and quick stir-frying or stir-frying at high heat are required, the three-layer heating pipes at the bottom of the stove 11 at the bottom of the cooking pot 1 are used for high-fire bottom heating, and then combined with the upper heating of the two light-wave heating lamps at the top of the inner cavity of the cooking machine, the cooking efficiency and cooking effect during cooking of a large amount of dishes or quick stir-frying or stir-frying at high heat can be greatly improved, the taste of the cooked dishes is better, and the nutritional loss during the cooking process is less.

[0081] A cleaning bump 10 is provided in the automatic cooking area to realize the knocking and vibrating cleaning function of the spatula mechanism. The cleaning bump 10 is installed on one side of the lower part of the inner cavity of the cooking machine where the spatula mechanism vertically flips and rises. The cleaning bump 10 can compress and knock the handles of the flat spatula 6 and the vertical spatula 7 on the spatula mechanism. The vertical surface of the cleaning bump 10 facing the inside of the cooking pot 1 is an inclined curved surface. When the spatula mechanism vertically flips through the cleaning bump 10, by using the elastic compression and rebound function of the handle of the flat spatula 6 or the vertical spatula 7 and the knocking function when the spatula flips back and encounters the obstruction of the cleaning bump 10 during rotation, the vegetable leaves, debris, etc. adhered to the flat spatula 6 or the vertical spatula 7 are knocked and vibrated and then fall into the pot. The automatic spatula cleaning function is also one of the important auxiliary functions for the automatic cooking device to achieve full-automatic cooking.

[0082] A cooking monitoring component 32 is added at the middle position of the top of the inner cavity of the cooking machine in the automatic cooking area. The cooking monitoring component includes a camera and an LED lamp. Temperature sensors are also provided on both the left and right sides at the bottom of the inner cavity of the cooking machine. The temperature sensors and the cooking monitoring component are used to monitor the temperature and video image information in the cooking pot 1 in real time. During the whole process of automatic cooking, the temperature and video image information obtained by the temperature sensors and the cooking monitoring component 32 are transmitted to the central processing module of the local control circuit and the central control system of the external tablet computer in real time. A camera lens brush automatic rotation and scrubbing mechanism is also provided in the cooking monitoring component 32 to remove the influence of the oil fume and hot steam generated during cooking on the camera and the LED lamp illumination at any time. The scrubbing mechanism directly drives the lens brush to rotate by a driving motor, thereby realizing the automatic scrubbing function of the monitoring camera lens and the LED lamp. The lens brush sponge is very simple and convenient to disassemble, clean or replace, and can be inserted and pulled out. The function of monitoring the temperature and video image information in the automatic cooking area is also one of the important auxiliary functions for the automatic cooking device to achieve intelligent full-automatic cooking.

[0083] The automatic feeding area includes special food and seasoning containers for automatic feeding, an automatic feeding special robotic arm and a food box lock, a horizontal automatic rotation control mechanism for the food box turntable, a vertical flipping and automatic feeding control mechanism for the food box and the robotic arm, a lower-layer moving gear horizontal rotation guiding and self-locking disc and a photoelectric positioning switch for the food box turntable, an automatic opening and closing mechanism for the blanking port flap, and an automatic feeding monitoring and identification system.

[0084] The automatic loading area features multiple specialized food and seasoning boxes 12 of varying shapes, sizes, and functions. These boxes 12 in this embodiment can also be any suitable container structure, such as food and seasoning cups or bottles. The automatic loading specialized food boxes are categorized by shape, size, and function: solid food boxes, egg beating cups, sauce mixing cups, solid or semi-solid / liquid mixture cups, and solid or liquid seasoning bottles. Each food and seasoning box 12, cup, or bottle is labeled with a QR code or electronic tag.

[0085] All the food and seasonings required for automatic loading in the automatic loading area can be manually processed and prepared, or purchased online or in physical stores from professional suppliers, which have been pre-processed and matched according to the requirements of the final dish, and then placed in a dedicated food box and sealed. When choosing to purchase pre-processed semi-finished dishes, all the food and seasonings required for a finished dish will be placed in a complete set of packaging boxes. This food preparation mode is very simple and convenient to operate. Before cooking each time, you only need to open the purchased packaging box, then open the fresh-keeping sealing film of each food and seasoning box 12, and hang all the food and seasoning boxes 12 on the corresponding automatic loading robot arm as required. Each food and seasoning box 12 is labeled with a two-dimensional barcode or electronic label containing information such as the type, weight, place of origin, and supplier of the food or seasoning. After the online food ordering platform, food pre-processing and side dish supply chain, industrial chain and cold chain distribution system are established and improved in the future, this standardized, digital, industrialized and intensive online food purchase and side dish preparation method will become the main food preparation mode when using automatic cooking devices in the future.

[0086] The automatic feeding area features a horizontal rotation control mechanism for the food box turntable, which is driven by a drive motor and a gear transmission mechanism, which in turn rotates a large, circular turntable. Multiple automatic feeding robotic arms are mounted on the food box turntable. The vertical flipping automatic feeding action for the specialized food boxes is driven by a drive motor that drives a fixed gear transmission mechanism located below and outside the centerline of the feed opening. This fixed gear transmission mechanism then rotates a mobile gear transmission mechanism mounted below each set of robotic arms on the food box turntable, which in turn drives the corresponding robotic arm and the food and seasoning box 12 suspended therefrom to automatically flip 180 degrees vertically, thereby pouring the food or seasoning into the wok 1 through the feed opening, completing the automatic feeding function.

[0087] To ensure the accuracy of the selected food ingredients or seasonings during automatic feeding, an automatic feeding monitoring and identification system is designed and installed above the inner side of the feeding port of the device. The system includes a monitoring and identification camera, an LED light, and a two-dimensional barcode or electronic tag label. The camera is aligned with the feeding port and the two-dimensional barcode or electronic tag label on the side of the top of the handle of the food ingredient and seasoning box 12 facing the camera. During the food ingredient confirmation before each feeding and the entire feeding process, the video image information collected by the camera will be transmitted in real time to the central processing module of the local control circuit and the central control system of the external tablet computer.

[0088] The dedicated food ingredient and seasoning box 12 is an important means and condition guarantee for accurately identifying, selecting, standardizing, and digitally managing various food ingredients and seasonings during the fully automatic feeding process. The advantages of using the dedicated food ingredient and seasoning box 12 are that it occupies less space, is flexible and convenient to control, has a wide range of applicable food ingredients and seasonings, is simple and convenient to load and unload, and can achieve standardized decomposition, specialized production, side dish preparation, networked cold chain logistics distribution, intelligent automatic processing and production, and full-process digital management for the food ingredients and seasonings required for any dish.

[0089] When the food ingredient box turntable rotates automatically and transfers the required food ingredient or seasoning box to the center line position of the feeding port, a set of moving gear transmission mechanisms installed under each robotic arm of the food ingredient box turntable meshes with the fixed gear transmission mechanism to form a new set of four-gear transmission mechanisms. By driving this set of four-gear transmission mechanisms with a driving motor, the robotic arm and the food ingredient and seasoning box 12 suspended on the robotic arm are driven to automatically flip 180° in the vertical direction, so that the food ingredient or seasoning is poured into the frying pan 1 through the feeding port, completing the automatic feeding function. By designing the food ingredient box turntable to rotate horizontally around the circumference of the frying machine body and installing an automatic feeding control mechanism on the food ingredient box turntable that can drive the food ingredient box to flip 180° in the vertical direction, the overall structure of the automatic feeding area is compact, occupies less space, the mechanical transmission mechanism is flexible and easy to drive, the circuit control is simple, the automatic feeding efficiency is high, the manufacturing cost is low, the operation is convenient and intuitive, and it can meet the fully automatic feeding needs for automatically frying the vast majority of dishes. To ensure the accurate and reliable position of the food ingredient box during automatic feeding, when it is in the non-automatic feeding position, it rotates smoothly in the horizontal direction and is self-locked and immovable in the vertical direction. An automatic feeding moving gear guiding and self-locking disc and a photoelectric positioning switch are also set, which further increases the accuracy, stability, reliability, and safety of the fully automatic feeding. To achieve full automation of the entire automatic feeding process, the automatic feeding area is also provided with a control mechanism for automatically opening and closing the feeding port flap. The automatic feeding function is also one of the important auxiliary functions for the automatic frying device to achieve intelligent and fully automatic frying.

[0090] The design solution of adding a temperature sensor and a stir-frying monitoring component 32 in the automatic stir-frying area and adding an automatic feeding monitoring and identification system in the automatic feeding area is an important guarantee for improving the intelligence and digital level of the automatic stir-frying device. The automatic stir-frying monitoring function and the automatic feeding monitoring function are also one of the important auxiliary functions for the automatic stir-frying device to achieve intelligent and digital fully automatic stir-frying.

[0091] During the whole process of automatic stir-frying, relying on the real-time temperature information of the temperature sensor in the stir-frying boiler 11, the real-time temperature information of the temperature sensor in the automatic stir-frying device, and the video image monitoring information of the stir-frying monitoring component 32, whether it is manual operation control or combined with the central control system of the tablet computer to achieve various intelligent automatic controls, it is possible to always master the actual situation of stir-frying in the stir-frying pot, so as to grasp the timing of stir-frying and conduct precise regulation. In addition, when automatically stir-frying some dishes or making non-stir-fried foods such as porridge, boiling dumplings, cooking noodles and making noodle soup, the function of preventing the pot from drying up or boiling over can also be realized. This not only greatly improves the stir-frying efficiency and stir-frying effect of the automatic stir-frying device, but also greatly improves the automation and intelligence level of the automatic stir-frying device. In order to eliminate the influence of the hot steam and oil fume generated during automatic stir-frying on the monitoring camera lens and LED lamp lighting, the solution also sets up an automatic rotating scrubbing mechanism for the video image monitoring camera lens, so as to ensure that the real-time situation in the stir-frying pot can be clearly and accurately observed throughout the whole process of automatic stir-frying.

[0092] During full-automatic feeding, through the automatic feeding monitoring and identification system, not only can the automatic feeding mechanism be commanded and controlled to accurately select the required food ingredients or seasonings, thus greatly improving the intelligence level of full-automatic feeding, but also because the automatic feeding monitoring and identification system can accurately master the food ingredient information put into the stir-frying pot each time, it is possible to control the heating process of various foods by the automatic stir-frying device according to the best nutritional health heating time and fire power intensity standards required for different food ingredients to achieve intelligent automatic control. This not only greatly reduces the nutrient loss, food waste and energy waste during automatic stir-frying, but also enables the taste and flavor of the food after processing to reach or approach the best state. At the same time, by using the cooperation between the automatic feeding monitoring and identification system and the central control system of the tablet computer, functions such as analyzing and calculating, storing and recording, and key prompting of all the calories and nutrient elements contained in all the food ingredients and seasonings used during the automatic stir-frying process can also be realized. In this way, it is possible to trace, query, analyze and utilize the whole-process information of automatic stir-frying, thus greatly improving the digital management ability and food safety guarantee ability of the automatic stir-frying device. This is not only beneficial for diners to understand the relevant diet and health data of each meal, but also can reasonably select and control the types, quantities and production standards of their meals according to their own specific conditions, so as to achieve the purpose of improving diet and health and diet therapy and health preservation.

[0093] A liquid adding mechanism is provided in the automatic sprinkling, spraying and draining area. The liquid adding mechanism includes a first water cup 13, a second water cup 14, a water valve for the second water cup, a sprinkling valve 15, a spray water pump 16, an annular sprinkling and spraying water pipe 19, a draining valve 18 and a draining pipe 17. The first water cup 13, the water valve for the second water cup, the sprinkling valve 15, the spray water pump 16 and the draining valve 18 are connected through a five-way water pipe. The sprinkling function and the spraying function share a sprinkling and spraying water pipe 19. The sprinkling and spraying water pipe 19 is designed to be circular and is fixed around the top of the inner cavity of the cooking machine. The sprinkling and spraying openings on the sprinkling and spraying water pipe 19 are evenly distributed in a circle on the lower side of the annular sprinkling and spraying water pipe 19, with an interval of about 20 mm. Each water outlet has three small water outlet holes, which are respectively directed towards the outer lower side direction, the inner lower side direction and the inner lower side direction close to the horizontal direction. The first water cup 13 and the second water cup 14 can be selected for use according to the actual water consumption of each automatic cooking. In order to meet the needs of automatic cooking of certain dishes, the first water cup 13 and the second water cup 14 are both equipped with heating and heat preservation functions, which are respectively controlled by the electric heating wires and temperature sensors in the first water cup 13 and the second water cup 14. When hot water is needed, just turn on the heating switch, and at this time the water temperature is generally controlled at 70°C - 80°C.

[0094] When automatically sprinkling, control the sprinkling valve 15 to open, and the water in the water cup will naturally flow out from the annular sprinkling and spraying water pipe 19 and flow down to the upper edge of the cooking pot, and then flow down along the side of the cooking pot to the bottom of the pot, so as to achieve the best sprinkling effect. When automatically spraying, start the spray water pump 16, and the sprinkling and spraying water pipe 19 sprays high-pressure water to clean the cooking pot 1, the side wall of the inner cavity of the cooking machine and the stir-fry shovel mechanism. At this time, the stir-fry shovel mechanism also rotates simultaneously in the horizontal and vertical directions. When automatically draining, the stirring cup 25 in the automatic stirring area will automatically rotate to the lower part of the water outlet of the draining pipe 17, and then automatically open the draining valve 18, and the remaining water in the water cup can be directly discharged into the stirring cup 25.

[0095] During the cooking process, it is often necessary to sprinkle some water to supplement the water loss after the food materials are heated, accelerate the dissolution of seasonings and better blend with the food materials. At the same time, the hot steam formed by sprinkling can also make the food materials cooked faster, more evenly, and the taste is also more delicious, crispy and tender. Moreover, sprinkling can also prevent the food materials at the bottom of the pot from sticking to the pot and burning. Therefore, the device is provided with an automatic sprinkling function. After each cooking is completed by the automatic cooking device, before performing the next automatic cooking task, in addition to needing to clean the cooking pot 1, it is generally also necessary to simply clean the stir-fry shovel mechanism. Therefore, the automatic cooking device is provided with an automatic spraying function that can simply and quickly clean the stir-fry shovel mechanism and the cooking pot 1. Since there may still be remaining unused water in the water cup after each complete cooking task, an automatic draining function is provided. The automatic sprinkling, spraying and draining functions are also one of the important auxiliary functions for the automatic cooking device to achieve intelligent and fully automatic cooking.

[0096] In the oil fume purification and emission filtration area, there is an oil fume purification and emission filtration mechanism installed on one side of the top inner cavity of the cooking machine, which is suitable for filtering the oil fume generated in the cooking pot 1 in real time. The oil fume purification and emission filtration mechanism is an integrated combined filtration device including three layers of oil fume filter nets 20 and two layers of oil fume filter ball packs 21, which can be conveniently loaded and unloaded. From the bottom layer to the upper layer of the three-layer stainless steel filter net, the mesh size of each layer gradually becomes smaller. The main function of the two filter ball packs is to use special high-temperature-resistant small balls that are easy to adsorb oil fume and odors to adsorb and filter most of the oil fume and odors passing through the filtration area.

[0097] Generally, more or less oil fume will be generated during cooking, and this oil fume will cause a certain degree of air pollution to the operation environment and dining environment. Since the automatic cooking device itself is a fully enclosed structure and the oil fume emission is already very small, adding an oil fume purification and emission filtration mechanism inside the automatic cooking device can further improve the environmental protection and green level of the automatic cooking device. Since this filtration device includes three layers of oil fume filter nets 20 and two layers of oil fume filter ball packs 21, the effect of oil fume purification and emission filtration is good, there is no energy consumption, the cost is low, the structure is simple, it is easy to load and unload, and it is convenient to clean. With this oil fume filtration device, users can use the automatic cooking device closely, for a long time, environmentally friendly and healthily. The oil fume purification and emission filtration function is also one of the important auxiliary functions for the automatic cooking device to achieve green cooking.

[0098] Adding a heat preservation and rice warming area 22 can not only further improve the thermal energy utilization rate and space utilization rate of the automatic cooking device, but also increase the usage functions of the automatic cooking device. At the same time, it also saves cooking time and improves cooking efficiency. The automatic opening and closing flip cover of the heat preservation and rice warming area 22 is directly driven by a driving motor to achieve the automatic opening and closing function.

[0099] The automatic exhaust area includes a movable partition net, an exhaust channel 23, an exhaust fan 24 and an automatic exhaust flip cover, etc. When there is no need to exhaust water vapor, the automatic exhaust flip cover can be closed; when a small amount of water vapor needs to be exhausted, the automatic exhaust flip cover is opened and the exhaust fan 24 does not move, and the water vapor in the cooking pot 1 can naturally rise and be exhausted in a small amount; when a large amount of water vapor needs to be quickly exhausted, the exhaust fan 24 is turned on again, and at this time the water vapor in the cooking pot 1 can be quickly exhausted. The switch of the exhaust fan 24 and the exhaust strength can be automatically adjusted, and the automatic exhaust flip cover is directly driven by a driving motor to the center shaft of the automatic exhaust flip cover to achieve automatic opening and closing.

[0100] For the large amount of hot steam generated during stir-frying, it is sometimes necessary to keep it enclosed to make full use of the hot steam to assist in heating the upper food ingredients, so that the stir-fried dishes are cooked faster and more evenly; while sometimes it is necessary to quickly discharge it to avoid affecting the taste, color, and flavor quality of the dishes due to too much water vapor in the pot. To improve the intelligent automatic control of the airtight utilization or rapid discharge of hot steam during automatic stir-frying, a fully automatic exhaust system is provided inside the automatic stir-frying device. The automatic exhaust function can either adopt a slower natural exhaust method, in which case the automatic exhaust flap is opened; or a faster exhaust fan forced exhaust method. This automatic exhaust system is faster, more efficient, and has better effects than the natural emission exhaust method of traditional manual stir-frying. The automatic exhaust function is also one of the important auxiliary functions for the automatic stir-frying device to achieve intelligent fully automatic stir-frying.

[0101] A stirring mechanism is installed in the automatic stirring area, which is suitable for stirring fluid materials that are prone to precipitation or uneven mixing and adding the stirred fluid materials into the stir-frying pan 1. The stirring mechanism consists of a whisking cup, a whisk 26, a stirring cup 25, and a stirring blade 27, and is composed of an automatic lifting control mechanism for the whisk 26 and stirring blade 27 assembly, an automatic rotation control mechanism for the whisk 26 and stirring blade 27 assembly, etc. The whisk 26 and the stirring blade 27 are an integrated combined component, with the whisk 26 on top and the stirring blade 27 below. The automatic lifting function of the whisk 26 and stirring blade 27 assembly is realized by a driving motor driving a gear transmission mechanism and a screw transmission mechanism, and the rotation function of the whisk 26 and stirring blade 27 assembly is directly driven by a stirring motor 31. When the automatic stirrer is whisking eggs, the rotation speed of the whisk 26 and stirring blade 27 assembly is medium and low speed; when stirring the sauce, the rotation speed of the whisk 26 and stirring blade 27 assembly is low speed.

[0102] When stir-frying, it is often necessary to beat the egg liquid and stir the sauce, especially the thickening sauce. Since there are starch substances in the thickening sauce, they are very easy to sink to the bottom, aggregate and harden. If the thickening sauce is not stirred before pouring it into the pan during stir-frying, the starch that has sunk to the bottom cannot be normally poured into the pan, and thus the thickening effect cannot be achieved. Therefore, during the automatic stir-frying process, it is necessary to stir the thickening sauce well before putting it in, but the stirring of the thickening sauce cannot be done too early, otherwise the starch will sink to the bottom again. The fully automatic stirring mechanism makes full use of the mechanical structure and usage function of the automatic feeding of the automatic stir-frying device, combines the egg-beating cup and the stirring cup 25 with the food and seasoning boxes 12 for automatic feeding, and at the same time integrates the egg-beater 26 and the stirring blade 27 into a combined component, and the egg-beater 26 and the stirring blade 27 have automatic lifting and automatic rotating functions. In addition, the stirring mechanism also has an automatic cleaning function. After the water in the first water cup 13 and / or the second water cup 14 flows into the stirring cup 25 through the water discharge valve and the water discharge port, the automatic cleaning of the egg-beater 26 and the stirring blade 27 can be realized by using the high-speed rotation function of the combined component of the egg-beater 26 and the stirring blade 27. The automatic stirring function is also one of the important auxiliary functions for the automatic stir-frying device to achieve intelligent and fully automatic stir-frying.

[0103] An automatic juice-making area is equipped with an automatic juice-making machine, which is composed of a juice cup 28, a juice-making blade 29, a rotation control mechanism, a juice-making machine working in place / reset rotation control mechanism, etc. The juice-making machine working in place / reset control mechanism directly drives the combined body of the juice-making machine and the juice cup 28 to rotate 180° forward and backward automatically by a driving motor. The juice-making blade 29 is directly driven by a juice-making motor 30 to rotate at a high speed or medium-high speed. After adding clean water to the juice cup 28 and the automatic juice-making machine is in place, the automatic cleaning of the blade can be realized by the high-speed rotation of the juice-making blade 29. Although the juice-making function is not an essential function of the automatic stir-frying device, freshly squeezed juice is a very popular beverage for diners when having stir-fried dishes.
