Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a fully automatic intelligent egg-beating and frying robot. Background Technology

[0002] An automatic egg-frying machine is a device that cracks eggs into a frying pan connected to an automatic flipping device. By heating the pan and automatically flipping it, the eggs are turned over, thus achieving automatic egg frying. This saves kitchen labor and improves processing efficiency. Chinese utility model patent (CN 215533621U) discloses an automatic egg-frying machine for kitchen use. It features an automatic egg-beating component and an automatic egg-frying component. After the egg-beating component cracks the eggs, the egg liquid flows into the frying pan of the automatic egg-frying component. The eggshells are sent to an external trash can via an eggshell discharge channel, thus achieving automatic egg-beating and frying operations and further improving the efficiency of egg frying. However, during the egg-beating process, impurities and dirt on the eggshells can easily enter the frying pan with the egg liquid, making it difficult to guarantee the hygiene of the fried eggs. Therefore, raw eggs need to be washed before being fed into the automatic egg-frying machine, which wastes manpower and increases labor costs. Furthermore, the aforementioned egg-frying machine can only heat the egg liquid from raw eggs. Oil needs to be manually poured into the frying pan, and after the eggs are fried and poured onto a plate, soy sauce needs to be sprayed on them by a chef or other staff. This results in inefficient egg-frying and a waste of human resources. In addition, the open structure of the machine allows external impurities to easily enter the frying pan during the frying process, making it difficult to control the quality of the fried eggs.

[0032] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0033] Please combine Figure 1 and Figure 2This invention provides a fully automatic intelligent egg-beating and frying robot 10, which can automatically clean eggs and spray cooking oil and soy sauce in a closed design to improve the quality of fried eggs. The robot 10 includes a shell assembly 100, an egg-beating rotation and cleaning assembly 200, an egg-tapping mechanism 300, an egg-frying assembly 400, and an oil-spraying assembly 500. The shell assembly 100 provides mounting points for the other components and creates a closed working area for the egg-frying operation, isolating it from the external environment and preventing external influences, thus improving the working environment, hygiene, and quality of the fried eggs. The egg-beating rotation and cleaning assembly 200 moves the eggs one by one to a preset beating position and cleans the eggs entering that position, rinsing away impurities and dirt from the egg surface to prevent impurities from the eggshell from mixing into the egg liquid during beating and contaminating it. The egg-cracking mechanism 300 is used to crack the egg, causing the bottom of the eggshell to break, allowing the egg white inside to flow out through the broken part under the influence of gravity, thus separating the eggshell from the egg liquid. The egg-frying component 400 is used to heat the egg liquid to form an edible fried egg, and the oil spraying component 500 is used to spray soy sauce into the frying pan of the egg-frying component 400 to season the fried egg.

[0034] For specific details, please refer to... Figure 1-3 The shell assembly 100 includes an egg tray 110, a middle shell 120 fixedly connected to the bottom of the egg tray 110, a clean / dirty water tank 130 connected to the bottom of the middle shell 120, and a flip cover 140 hinged to one side of the top of the egg tray 110 and capable of closing on the egg tray 110. The egg tray 110, the middle shell 120, and the clean / dirty water tank 130 together enclose an egg-frying space. The middle shell 120 has an egg-removing opening 121 on its circumferential side that communicates with the egg-frying space. The middle shell 120 has an egg-removing door 150 located at the egg-removing opening 121 that can be opened and closed. The clean / dirty water tank 130 includes a separately provided clean water tank 131 and a dirty water tank 132 that communicates with the egg-frying space. In this embodiment, the middle shell 120 is located below the egg tray 110 and connected to one side of the bottom of the egg tray 110. Thus, when the egg tray 110, the middle shell 120 and the clean / sewage tank 130 are assembled together, the area below the egg tray 110 that is not enclosed by the middle shell 120 forms the egg retrieval opening 121. The egg retrieval opening 121 is closed by the egg retrieval door 150 during the egg frying operation. After the egg frying is completed, the egg retrieval door 150 is opened, and the operator can take out the fried egg through the egg retrieval opening 121.

[0035] In one embodiment, the bottom of the middle shell 120 is provided with a bottom plate 122, and the clean / sewage tank 130 is removably mounted on the bottom plate 122. Thus, when the sewage compartment 132 of the clean / sewage tank 130 is full, the operator can pull out the clean / sewage tank 130 and empty the sewage to prevent overflow due to excessive sewage in the sewage compartment 132. In this embodiment, the bottom plate 122 is mounted on the bottom of the middle shell 120 via a bottom plate 122 fixing bracket. The height of the bottom plate 122 fixing bracket is the same as that of the clean / sewage tank 130. The top of the bottom plate 122 fixing bracket is provided with a sealing plate for sealing the bottom of the middle shell 120, thereby limiting the movement of the internal components of the middle shell 120. The clean / wastewater tank 130 includes a box body 133 with an opening at the top and a box cover 134 that is sealed and closed on the top of the box body 133. The inner cavity of the box body 133 is provided with a partition 135 to separate the inner cavity of the box body 133 into a clean water tank 131 and a wastewater tank 132. The box cover 134 has several drainage holes 136 in the area corresponding to the wastewater tank 132 so that the egg washing water generated in the egg frying space flows into the wastewater tank 132 for unified collection.

[0036] In this embodiment, a power board bracket 123 is provided on the middle shell 120 near the clean / dirty water tank 130. A power board 124 is installed on the outside of the power board bracket 123. The power board 124 is electrically connected to an external power source through a filter socket 125. A water pump 126 is provided on the side of the power board bracket 123 near the clean water tank 131. The water pump 126 is electrically connected to the power board 124 and is used to pump clean water to the egg-beating and cleaning assembly 200. The working end of the water pump 126 is located inside the clean water tank 131, and a silicone sleeve 127 is provided on the water pump to achieve waterproof protection of the connection between the water pump 126 and the power board 124. In addition, in this embodiment, a gripping handle 137 is provided on the side wall of the box 133 outside the egg-frying space. Preferably, the side wall of the box 133 outside the egg-frying space is recessed to form a clearance area. The clearance area is provided with a gripping handle 137 for finger gripping to reduce the difficulty of taking out and placing the clean / dirty water tank 130.

[0037] It should be noted that in other embodiments, the bottom plate 122 at the bottom of the middle shell 120 can be omitted. That is, the clean / dirty water tank 130 can be directly pushed into the area enclosed by the bottom of the middle shell 120 and the egg retrieval door 150 to seal the bottom of the frying space. In this case, the edge of the lid 134 of the clean / dirty water tank 130 is provided with a sealing ring that seals against the bottom of the egg retrieval door 150 and the inner side of the middle shell 120 to prevent egg washing water from flowing out through the gaps between the clean / dirty water tank 130, the egg retrieval door 150 and the middle shell 120 during the frying process, thereby reducing the impact of the frying operation on the external environment.

[0038] Furthermore, the egg retrieval door 150 includes a door hinged to the middle shell 120, or the egg retrieval door 150 includes two doors that are opposite to each other and respectively hinged to the middle shell 120; the egg retrieval door 150 is provided with a pull buckle 151. In other embodiments, the egg retrieval door 150 can also slide with the middle shell 120, that is, a slide rail is provided on the inner wall of the middle shell 120, and the egg retrieval door 150 is installed on the slide rail, or guide rails are provided on the bottom of the egg tray 110 and the cover 134 of the clean / dirty water tank 130, and the egg retrieval door 150 is installed on the guide rails, so as to realize the sliding engagement between the egg retrieval door 150 and the middle shell 120.

[0039] The top surface of the flip cover 140 is equipped with a touch screen display 141, and the inner side of the flip cover 140 is equipped with a PCBA board 142 electrically connected to the touch screen display 141. The PCBA board 142 is used to control the operation of the entire machine. The flip cover 140 includes an upper cover plate 143 and a lower cover plate 144 that are arranged opposite to each other and enclose a closed area. The upper cover plate 143 has a display port. The touch screen display 141 is housed in the closed area and corresponds to the display port. The PCBA board 142 is housed in the closed area and electrically connected to the touch screen display 141. In this embodiment, the flip cover 140 is equipped with a status indicator light and a speaker electrically connected to the PCBA board 142. Thus, when the egg-frying robot is in different working conditions, the status indicator light indicates different colors so that the operator can judge the current egg-frying progress based on the color of the status indicator light. When the egg-frying operation is completed or the equipment malfunctions, the PCBA board 142 controls the speaker to work so that the operator can respond quickly. In addition, in this embodiment, a door drive mechanism that is electrically connected to the PCBA board 142 and used to open and close the egg retrieval door 150 can also be provided on the middle shell 120. The door drive mechanism can be a solenoid valve, which is located at the part where the movable end of the egg retrieval door 150 cooperates with the egg tray 110. At the same time, an elastic element is also provided at this part. In this way, when the solenoid valve is activated, the egg retrieval door 150 will be opened by the elastic force of the elastic element, so as to realize the automatic opening of the egg retrieval door 150.

[0040] Please combine Figure 1-7The egg-beating rotation and cleaning assembly 200 includes an egg-beating rotation rack 210 located between the egg tray 110 and the flip cover 140 and rotatably connected to the egg tray 110, and a first drive mechanism 220 fixed on the egg tray 110 for driving the egg-beating rotation rack 210 to rotate intermittently. The egg tray 110 is provided with an annular egg slide 111 for receiving raw eggs. The annular egg slide 111 has an egg-beating and cleaning port 112 communicating with the egg-frying space, and a shell-dropping port 113 adjacent to the egg-beating and cleaning port 112 and communicating with the egg-frying space. The egg-frying space is provided with a trash can 114 corresponding to the shell-dropping port 113 for receiving egg shells. The bottom of the egg-beating rotation rack 210 is provided with a prying part corresponding to the annular egg slide 111 for pushing eggs into the egg-beating and cleaning port 112 and pushing egg shells into the shell-dropping port 113. Preferably, the inner diameter of the egg-cleaning opening 112 is smaller than the diameter of the egg when it is vertically positioned, so that when the egg moves to the egg-cleaning opening 112, a part of the egg is located below the egg-cleaning opening 112, and the egg can be confined within the egg-cleaning opening 112 by the constraint of the inner wall of the egg-cleaning opening 112.

[0041] Furthermore, the bottom surface of the egg-beating rotating rack 210 is provided with a plurality of actuating tubes 211 spaced out in a ring. The bottom opening of each actuating tube 211 forms an actuating part for covering the egg pancake and moving the egg or eggshell. More preferably, the top of the egg-beating rotating rack 210 is provided with a guide tube 212 spaced out along a ring path, corresponding to each actuating tube 211. Each guide tube 212 has the same inner diameter as its corresponding actuating tube 211 and they are connected one-to-one. In this way, a plurality of egg placement positions can be formed in a ring on the egg-beating rotating rack 210, and the minimum diameter of the guide tube 212 and the actuating tube 211 is greater than the maximum diameter of the egg. The first drive mechanism 220 includes a support plate 221 mounted in the middle of the egg tray 110, a rotating shaft 222 rotatably mounted on the support plate 221 and fixedly connected to the egg-beating rotating frame 210, a bearing 223 sleeved on the rotating shaft 222, and a first servo motor 224 fixed on the egg tray 110 and electrically connected to the PCBA board 142 to drive the rotating shaft 222 to rotate. In order to reduce the rotation speed of the egg-beating rotating frame 210, the output end of the first servo motor 224 is also provided with a gear or gear set, and a transmission gear coaxially mounted on the rotating shaft 222 to mesh with the gear or the gear at the output end of the gear set, so as to realize the adjustment of the rotation speed of the rotating shaft 222.

[0042] Before frying the eggs, the operator opens the flip cover 140 and can load several eggs into the guide tubes 212 on the egg-beating rotating rack 210 at once. The eggs fall into the annular egg slide 111 of the egg tray 110 through the guide tubes 212 and the agitator tube 211 and are constrained by the inner wall of the agitator tube 211. When the first servo motor 224 drives the rotating shaft 222 to rotate, the egg-beating rotating rack 210 will drive the eggs in the agitator tube 211 to move along the annular egg slide 111 of the egg tray 110, so that each egg moves to the egg-beating cleaning port 112 on the egg tray 110 one by one, so that it can be cracked at the egg-beating cleaning port 112.

[0043] In this embodiment, an egg pressing rack 115 is provided next to the egg washing port 112 inside the annular egg slide 111, which communicates with the water tank 131 and sprays water onto the eggs. Further, the egg pressing rack 115 is a hollow tube with an inverted L-shaped structure, including a vertical section connected to the water tank 131 via a water pipe and a horizontal section perpendicularly connected to the vertical section. The horizontal section and / or the vertical section have several water outlets communicating with the inner cavity of the egg pressing rack 115. The water pipe is connected to a water pump, and a high-pressure nozzle is provided at each water outlet. By setting up the egg pressing rack 115, on the one hand, when the egg moves to the egg-beating and cleaning port 112, the inner edge of the egg-beating and cleaning port 112 can be used to limit the egg. The horizontal and vertical parts of the egg pressing rack 115 work together to limit the egg entering the egg-beating and cleaning port 112, preventing the egg from moving to the side of the egg-beating and cleaning port 112 under the action of inertia, thus causing the egg-beating mechanism 300 to fail to contact the egg and causing the egg-beating failure. On the other hand, the water outlet on the egg pressing rack 115 can spray high-pressure cleaning water to wash away impurities on the surface of the egg, preventing impurities on the eggshell from mixing into the egg liquid during the egg-beating process. Of course, a spray pipe connected to the clean water tank can also be installed on the side of the egg-beating and cleaning port 112 facing away from the shell-dropping port. Similarly, a flow channel for guiding the wastewater after cleaning into the egg-frying space can be installed below the spray pipe. In this way, the eggs can be cleaned before entering the egg-beating and cleaning port 112, so that the water on the surface of the eggs can be drained in time after cleaning, and the residual water on the surface of the eggs will not be mixed into the egg liquid due to the water not being drained during the egg-beating process.

[0044] Please combine Figure 2 , 89. The egg-tapping mechanism 300 includes a tapping bracket 310 installed below the egg tray 110 and corresponding to the egg-beating and cleaning port 112, and a second drive mechanism fixed on the egg tray 110 for driving the tapping bracket 310 to rotate. The tapping bracket 310 has a tapping part 320 on its circumferential side that periodically taps the bottom of the egg when rotating. Preferably, the tapping part 320 is a protrusion on the circumferential side of the tapping bracket 310. The second drive mechanism includes a second servo motor 330 electrically connected to the PCBA board 142, and a connecting shaft 340 drivenly connected to the output shaft of the second servo motor 330 and rotatingly cooperating with the egg tray 110. The tapping bracket 310 is fixedly installed on the connecting shaft 340. When the egg moves to the egg-beating and cleaning port 112, the PCBA board 142 controls the second servo motor 330 to operate, causing the coupling 340 to drive the striking bracket 310 to rotate. Thus, the striking part 320 periodically approaches and strikes the bottom of the egg, causing the bottom to break and allowing the egg liquid to flow out of the shell. It should be noted that in this embodiment, a sensing device can also be installed at the egg-beating and cleaning port 112. This sensing device can be a gravity sensor, a vision sensor, or another contact switch. When the egg moves to the egg-beating and cleaning port 112, the potential of the gravity sensor, vision sensor, and contact switch will change. The PCBA board 142 determines that the egg has moved to the egg-beating and cleaning port 112 based on the potential change of the sensing device and then controls the second servo motor 330 to operate to strike the egg. Of course, PCBA board 142 can also determine the position of the egg based on the rotation speed of the first servo motor 224 and the transmission coefficient of the gear, or set a timer electrically connected to PCBA board 142 so that PCBA board 142 controls the second servo motor 330 to work at preset intervals to knock the egg.

[0045] To prevent eggshells from falling into the frying pan, in one embodiment, the egg-beating and cleaning port 112 is covered with an eggshell filter rack 116 for accommodating eggs and separating egg whites and liquids. The eggshell filter rack 116 has several holes to allow the liquid to pass through, while the eggshells are trapped by the filter rack 116, thus achieving separation of the eggshells and liquids. After the egg is cracked, the liquid flows out along the bottom of the eggshell filter rack 116, while the eggshells are pushed to the shell-dropping port 113 by the agitator tube 211 at the bottom of the egg-beating rotating rack 210, causing the eggshells to leave the annular egg slide 111. In this embodiment, the fully automatic intelligent egg-beating and frying robot 10 also includes an eggshell slide 117 fixed on the egg tray 110 and disposed at the edge of the eggshell drop opening 113. The top of the eggshell slide 117 communicates with the eggshell drop opening 113, and the bottom of the eggshell slide 117 communicates with the trash can 114. By setting the eggshell slide 117, the path of the falling eggshells can be limited to prevent the eggshells from falling onto the lid 134 of the clean / sewage tank 130, thereby maintaining the cleanliness of the egg-frying space. Furthermore, the trash can 114 is placed on the lid 134 or hung on the inner surface of the middle shell 120.

[0046] Please combine Figure 2 as well as Figure 10-12 The egg-frying assembly 400 is housed within the egg-frying space and includes a frying pan located below the egg-beating and cleaning port 112, a handle 410 connected to one side of the frying pan, and a third drive mechanism mounted on the middle shell 120 and drivenly connected to the handle 410 to drive the frying pan to flip. The frying pan includes a lower frying pan 420 fixedly connected to the handle 410, an upper frying pan 430 hingedly connected to the handle 410, and a fourth drive mechanism 440 drivenly connected to the upper frying pan 430 and driving the upper frying pan 430 to rotate so that the upper frying pan 430 and the lower frying pan 420 are closed or separated. The upper frying pan 430 and the lower frying pan 420 heat up during operation to heat the egg mixture. In this embodiment, the lower frying pan 420 and the upper frying pan 430 enclose a working area for frying eggs. The lower frying pan 420 includes a lower frying pan inner shell 421 fixedly connected to the handle 410, a lower frying pan outer shell 422 fixedly connected to the side of the lower frying pan inner shell 421 facing away from the working area, a first heating copper tube 423 housed between the lower frying pan inner shell 421 and the lower frying pan outer shell 422 and electrically connected to the PCBA board 142, and a first heat insulation sheet 424 disposed between the first heating copper tube 423 and the lower frying pan outer shell 422. The upper frying pan 430 includes an upper frying pan inner shell 431 hinged to the handle 410, an upper frying pan outer shell 432 fixedly connected to the side of the upper frying pan inner shell 431 facing away from the working area, a second heating copper tube 433 housed between the upper frying pan inner shell 431 and the upper frying pan outer shell 432 and electrically connected to the PCBA board 142, and a second heat insulation sheet 434 disposed between the second heating copper tube 433 and the upper frying pan outer shell 432.

[0047] Furthermore, the third drive mechanism includes a third servo motor 450 electrically connected to the PCBA board 142 and a gear transmission mechanism 460 driven by the third servo motor 450; the fourth drive mechanism 440 includes a fourth servo motor 441 housed in the handle 410, a first gear 442 driven by the output shaft of the fourth servo motor 441, a second gear 443 parallel to and meshing with the first gear 442, and a gear shaft 444 passing through and fixedly connected to the second gear 443. The gear shaft 444 is fixedly connected to one side of the inner shell 431 of the upper frying pan to drive the inner shell 431 of the upper frying pan to rotate. Preferably, the second gear 443 has a semi-circular structure, and the central angle corresponding to the area where the teeth of the second gear 443 are set is 180°, that is, after the second gear 443 meshes with the first gear 442, it can only rotate within a 180° rotation range.

[0048] In this embodiment, before frying the eggs, during the egg washing process, the upper frying pan 430 and the lower frying pan 420 are closed to prevent washing water from flowing into the working area. After the egg washing is completed and before the egg cracking operation, the fourth servo motor 441 drives the first gear 442 to rotate, which in turn drives the second gear 443 and the gear shaft 444 to rotate through meshing. This causes the inner shell 431 and the outer shell 432 of the upper frying pan to rotate synchronously. In this case, the movable end of the upper frying pan 430 moves away from the lower frying pan 420, so that the egg liquid from the cracked egg at the egg washing port 112 flows into the lower frying pan 420. After the egg liquid enters the lower frying pan 420, the PCBA board 142 controls the output shaft of the fourth servo motor 441 to rotate in the opposite direction while controlling the second servo motor 330 to stop working, so that the upper frying pan 430 and the lower frying pan 420 are closed to form a closed working area. To ensure even heating of the fried egg, after controlling the first heating copper tube 423 and the second heating copper tube 433 to operate and heat the egg liquid for a preset time, the PCBA board 142 will control the third servo motor 450 to operate, so as to drive the closed upper frying pan 430 and lower frying pan 420 to flip through the handle 410, so that the fried egg can be flipped over, so as to heat the other side of the fried egg and prevent the fried egg from burning in some areas due to uneven heating.

[0049] In this embodiment, the third servo motor 450 and the gear transmission mechanism 460 together form a gearbox. The gearbox has a flip-mounted fixing bracket and a mounting bracket mounted on the flip-mounted fixing bracket at the output end of the gear transmission mechanism 460. The handle 410 engages with this mounting bracket via a male mounting connector. Thus, when the user's frying pan is damaged, the frying pan and handle can be removed and replaced simultaneously without purchasing a new unit, reducing the user's operating costs.

[0050] In addition, the handle 410 is provided with a drain pipe 470 that extends into the working area and communicates with the clean water tank 132. The drain pipe 470 is installed on the toothed box through a water pipe connector to communicate with the water supply pipe laid on the toothed box, and is removed simultaneously when the frying pan is changed. It should be noted that in this embodiment, the water outlet of the egg pressing rack can not only provide water for washing eggs, but also, after the egg frying operation is completed and the upper and lower frying pans are opened, cleaning water can be injected into the frying pan through the water outlet of the egg pressing rack to clean the frying pan. At the same time, while water is injected into the frying pan through the water outlet, the cleaning water sprayed from the water outlet can also clean the egg cracking mechanism to keep the egg cracking mechanism clean. Furthermore, the egg pressing rack can also be T-shaped, with one end of the horizontal section extending towards the shell-feeding opening and the other end extending towards the egg-beating and cleaning opening. Several water outlets are provided at both ends of the horizontal section of the egg pressing rack. This allows for cleaning not only the egg-beating and cleaning opening, the eggs, and the frying pan, but also the cleaning water sprayed from the rack to clean the eggshell tracks. In this embodiment, the drain pipe 470 has an L-shaped structure, with its end extending to the bottom of the upper frying pan or the bottom of the lower frying pan. The wastewater tank 132 is equipped with a wastewater pump for drawing oil from the work area into the wastewater tank 132 via the drain pipe 470. After the frying pan cleaning operation is completed, the upper and lower frying pans are closed, and the wastewater pump directly draws out the wastewater from the frying pan via the drain pipe 470. Alternatively, after the frying pan is flipped over, the wastewater pump draws out the wastewater from the frying pan via the drain pipe 470 to discharge the cleaning wastewater from the frying pan.

[0051] The oil spraying assembly 500 includes a soy sauce tank 510 and an edible oil tank 520 mounted on the middle shell 120, an oil pipe 530 communicating with the soy sauce tank 510 and the edible oil tank 520 respectively and whose output end corresponds to the frying pan, a soy sauce pump 540 for drawing soy sauce into the oil pipe 530, and an edible oil pump 550 for drawing edible oil into the oil pipe 530. In this embodiment, the oil pipe 530 is arranged inside the middle shell 120. The input end of the oil pipe 530 is provided with a T-junction to communicate with the soy sauce tank 510 and the edible oil tank 520 respectively. The output end of the oil pipe 530 extends from below the egg-cracking assembly 400 through the area between the egg-cracking and cleaning port 112 and the egg-dropping port 113, so as to avoid interference between the soy sauce spraying and the egg-cracking operation. In the egg-frying process, the cooking oil pump 550 first operates and draws cooking oil into the oil pipe 530, allowing the oil to flow into the frying pan through the output end of the oil pipe 530. After the eggs are washed and cracked, the egg liquid flows into the frying pan and is heated. Simultaneously, the soy sauce pump 540 operates and draws soy sauce into the oil pipe 530, allowing the soy sauce to flow onto the fried eggs in the frying pan through the output end of the oil pipe 530, thus achieving soy sauce spraying. Furthermore, the inner wall of the middle shell 120 is provided with mounting grooves for embedding the soy sauce tank 510 and the cooking oil tank 520. The cooking oil tank 520 is positioned above the soy sauce tank 510; alternatively, the soy sauce tank 510 can also be positioned above the cooking oil tank 520.

[0052] The fully automatic intelligent egg-beating and frying robot 10 of this utility model features an egg-pressing rack 115 installed beside the egg-beating and cleaning port 112. This rack serves two purposes: firstly, it positions the eggs entering the egg-beating and cleaning port 112 to prevent displacement during beating; secondly, it functions as a spray nozzle for rinsing and cleaning the eggs. The water from the egg-washing process flows through the egg-beating and cleaning port 112 into the frying space and into a wastewater tank, preventing overflow of washing water and avoiding the mixing of impurities and dirt from the eggs into the egg mixture, thus preventing hygiene issues in the fried eggs. The rack 115 can also provide water for cleaning the frying pan; by setting up a soy sauce tank 510, an oil tank 520, an oil pipe 530, a soy sauce pump 540, and an oil pump 550, it can realize the automatic spraying of oil before frying eggs and the automatic spraying of soy sauce during the frying process, eliminating the need for manual spraying of oil and soy sauce, which helps to save manpower; by setting up a middle shell 120 and an egg-removing door 150, the frying robot has achieved a closed design, which can prevent dirty water from overflowing during the egg washing process and prevent external impurities from easily entering the frying pan, which is conducive to controlling the quality of fried eggs.
