Description

Technical Field

[0001] This utility model relates to the field of intelligent cooking equipment technology, specifically to a multi-station intelligent cooking device. Background Technology

[0002] To improve meal preparation efficiency, a multi-station intelligent cooking device with multiple cooking stations has emerged on the market. It can intelligently and automatically control the heating of the lunch box to cook the ingredients inside according to the set program.

[0003] Referring to the technical solution of application number 202210411435.X, this multi-station intelligent cooking device typically includes a housing, a heating chamber for placing lunch boxes, and a drive device for rotating the heating chamber. Both the heating chamber and the drive device are installed inside the housing. The front ring of the heating chamber is supported by rollers, and the rear is supported by a bearing seat to ensure stable operation. When the heating chamber heats the lunch box and its contents, the drive device rotates the heating chamber, causing the contents to tumble and thus ensuring even heating.

[0004] However, to prevent the food containers from deforming or bursting due to excessive internal pressure during heating, vents are usually provided on them. During heating, steam carrying grease escapes, forming fumes. However, this technology lacks a fume collection or exhaust structure, causing the fumes to accumulate on the inner walls of the heating chamber and the back of the door, affecting the cleanliness of the multi-station smart cooking equipment. Furthermore, when the user opens the door, residual steam condenses into water droplets at the door and heating chamber openings, dripping onto the surrounding ground and polluting the environment, increasing cleaning difficulty. Additionally, this technology lacks a heat dissipation structure. Multiple heating devices operating simultaneously generate a large amount of heat, and insufficient heat dissipation can easily lead to excessively high internal temperatures in the multi-station smart cooking equipment, affecting the stable operation of internal electronic components and potentially posing safety hazards. Therefore, improvements are needed. Utility Model Content

[0022] Reference Figure 1-17 A multi-station intelligent cooking device includes a housing 1, a control module 2 mounted on the housing 1, multiple doors 3, and multiple heating devices 4. The housing 1 has multiple heating stations 101 communicating with its interior, arranged horizontally and vertically. Each heating station 101 corresponds to at least one heating device 4, which is electrically connected to the control module 2. Each door 3 corresponds to at least one heating station 101 and is closable on the housing 1 to close or expose the corresponding heating station 101. The housing 1 also has an exhaust assembly module for extracting heat from the interior of the housing 1 and for extracting fumes from the heating devices 4 and venting them to the outside of the housing 1. The exhaust assembly module is connected to and controlled by the control module 2, and each heating device 4 corresponds to one exhaust assembly module.

[0023] In this embodiment, the control module 2 is connected to a cooking information acquisition module 5 for acquiring cooking information of the lunch box. The cooking information acquisition module 5 includes a barcode scanning unit 51 and a barcode scanning mounting base 52. The barcode scanning unit 51 can scan the identification code on the lunch box to obtain the cooking parameters of the lunch box. The control module 2 parses the cooking parameters in the identification code according to a preset program and automatically matches the corresponding heating device 4 and working mode to achieve the purpose of accurately heating the lunch box.

[0024] Furthermore, the box body 1 is provided with a barcode scanning window 102 communicating with the interior of the box body 1. The barcode scanning mounting base 52 is installed inside the box body 1 and corresponds to the barcode scanning window 102. The barcode scanning unit 51 is located inside the box body 1 and is installed on the barcode scanning mounting base 52. The barcode scanning mounting base 52 is provided with a scanning hole 521 for the scanning head of the barcode scanning unit 51 to be exposed. The scanning head of the barcode scanning unit 51 is tilted downwards toward the barcode scanning window 102, so that when the user places the lunch box in the barcode scanning window 102, the scanning head of the barcode scanning unit 51 can capture the identification code information at the optimal angle, thereby improving the barcode scanning success rate.

[0025] Furthermore, the barcode scanner mounting base 52 is provided with a scanning clearance groove 522 corresponding to the scanning window. The scanning hole 521 passes through the scanning clearance groove 522 to ensure that the barcode scanner mounting base 52 will not interfere with the line of sight of the scanning head of the barcode scanner unit 51. At the same time, the size of the scanning window is configured such that the lunch box cannot pass through the barcode scanner window 102 and enter the scanning clearance groove 522, thereby reducing the probability of the lunch box affecting the barcode scanner unit 51.

[0026] In this embodiment, the housing 1 is equipped with a speaker 6 for playing voice prompts, a touch screen 7 for displaying working data and operating interface, and a main switch 8 for controlling the opening and closing of the entire multi-station intelligent cooking equipment. The speaker 6, touch screen 7 and main switch 8 are all electrically connected to the control module 2 to provide real-time voice guidance and visual interface feedback during user operation, thereby improving the user experience.

[0027] Furthermore, both the speaker 6 and the touch screen 7 are housed inside the enclosure 1. The side wall of the enclosure 1 is provided with a sound outlet array 103 corresponding to the position of the speaker 6 and a display window 104 corresponding to the position of the touch screen 7. The sound outlet array 103 is composed of multiple sound outlet holes and is used to ensure that the sound from the speaker 6 is transmitted outside the enclosure 1. The display window 104 is used to fully expose the display interface of the touch screen 7, making it convenient for the user to observe the operation status and heating progress.

[0028] Furthermore, the front side of the housing 1 is provided with a switch window 105 corresponding to the main switch 8. The housing 1 is provided with a switch mounting base 9, and the main switch 8 is mounted on the switch mounting base 9. The switch window 105 is closed by a sliding cover 100, which is slidably mounted on the housing 1. For example, the inner front wall of the housing 1 is provided with two lifting slides 106 located at the left and right ends of the switch window 105 and a cover plate support slot 107 located between the bottom of the two lifting slides 106. The left and right ends of the sliding cover 100 are respectively slidably engaged in the two lifting slides 106. When the sliding cover 100 moves upward, the switch window 105 can be opened; when the sliding cover 100 descends and its bottom is inserted into the cover plate support slot 107, the sliding cover 100 blocks and closes the switch window 105, thereby preventing external factors from damaging the main switch 8.

[0029] In this embodiment, the scanning window 102, the sound hole array 103, the display window 104, and the switch window 105 are all located at the front end of the enclosure 1. The display window 104, the scanning window 102, the sound hole array 103, and the switch window 105 are arranged from top to bottom so that they are located on the same side of the enclosure 1, which is convenient for user operation.

[0030] In this embodiment, the door 3 is provided with a latch 31, which is correspondingly engaged with a door lock device 10 installed on the box body 1. The door lock device 10 is used to control the opening and closing state of the door 3 in conjunction with the latch 31. The door lock device 10 is connected and controlled by the control module 2. After the scanning unit 51 scans the identification code on the lunch box, the control module 2 automatically selects to open an empty door 3 according to the idle state of the heating station 101, allowing the user to put the lunch box into the heating device 4 corresponding to the door 3. The control module 2 controls the heating device 4 to heat the lunch box according to the lunch box cooking information obtained by scanning.

[0031] In this embodiment, the heating station 101 is a heating window located on the front side of the box 1 and communicating with the inside of the box 1. The heating device 4 includes a heating chamber 41 for placing a lunch box, a heating device for heating the lunch box, and a driving device 42 for driving the heating chamber 41 to rotate. The heating chamber 41 is rotatably disposed inside the box 1, and the interior of the heating chamber 41 is a heating cavity for placing the lunch box. The heating device is installed on the heating chamber 41, and the rotation output end of the driving device 42 is connected to the heating chamber 41 in a transmission connection.

[0032] In this embodiment, the housing 1 is provided with a heating mounting frame 11. The upper and lower ends of the heating mounting frame 11 are connected to the inner top wall and the inner bottom wall of the housing 1, respectively. The heating device 4 also includes a mounting bearing seat 43 and a mounting ring 44. The mounting bearing seat 43 is mounted on the heating mounting frame 11. One end of the heating chamber 41 is provided with a mounting shaft that fits on the mounting bearing seat 43. The mounting ring 44 is mounted on the other end of the heating chamber 41. The housing 1 is provided with a roller assembly 12 corresponding to the mounting ring 44. The roller assembly 12 includes a roller bracket 121 fixed on the housing 1 and a plurality of auxiliary rollers 122 rotatably mounted on the roller bracket 121. The roller surface of the auxiliary rollers 122 rolls in contact with the outer peripheral surface of the mounting ring 44 and supports the mounting ring 44, thereby achieving the purpose of rotatably placing the heating chamber 41 inside the housing 1.

[0033] In this embodiment, for ease of processing, the heating chamber 41 is composed of a first half-shell 411 and a second half-shell 412. The first half-shell 411 and the second half-shell 412 are connected by bolts. The inner cavity of the first half-shell 411 and the inner cavity of the second half-shell 412 form the heating chamber. The rear end of the first half-shell 411 is integrally formed with a first half-shaft 4111, and the rear end of the second half-shell 412 is integrally formed with a second half-shaft 4121. The first half-shaft 4111 and the second half-shaft 4121 are assembled to form the mounting shaft.

[0034] Furthermore, the inner ring of the mounting ring 44 is provided with a turntable insertion hole 442 and a turntable through hole 443 coaxially arranged with the mounting ring 44. A ring stop surface is provided between the turntable insertion hole 442 and the turntable through hole 443. The front end of the first half-shell 411 is provided with a first arcuate protrusion 4112, and the front end of the second half-shell 412 is provided with a second arcuate protrusion 4122. The first arcuate protrusion 4112 and the second arcuate protrusion 4122 combine to form a mating ring that fits into the turntable insertion hole 442. When the mating ring is inserted into the turntable insertion hole 442 and its front end abuts against the ring stop surface... When the mating ring can no longer be inserted into the turntable insertion hole 442, the outer wall of the mating ring contacts the hole wall of the turntable insertion hole 442. The turntable through hole 443 is directly opposite the inner ring of the mating ring. Then, the first half shell 411 and the second half shell 412 are fixedly connected to the mounting ring 44 by bolts, thereby realizing the synchronous rotation of the heating chamber 41 and the mounting ring 44. At the same time, the connection quality of the first half shell 411 and the second half shell 412 is more stable and reliable under the constraint of the mounting bearing seat 43 and the mounting ring 44, effectively avoiding loosening during operation.

[0035] In this embodiment, a heat insulation panel 48 is provided inside the heating cavity. The heat insulation panel 48 is preferably a microcrystalline panel. The heat insulation panel 48 can provide a certain degree of insulation between the food container and the heating cavity, preventing excessive heat from the food container from damaging the internal structure of the heating chamber 41. Furthermore, both the first half-shell 411 and the second half-shell 412 have microcrystalline mounting surfaces inside their respective cavities. The microcrystalline mounting surfaces on the first half-shell 411 and the second half-shell 412 are positioned opposite each other, and the microcrystalline mounting surfaces have panel mounting grooves for embedding the heat insulation panel 48.

[0036] In this embodiment, the heating chamber 41 is equipped with a temperature sensor 49 connected to the control module 2, which is used to monitor the temperature change in the heating chamber in real time and feed the temperature data back to the control module 2, thereby improving the control accuracy of the heating device 4 and ensuring the heating quality of the lunch box to be heated by each heating device 4.

[0037] In this embodiment, the heating device includes a coil 300 outside the heating chamber 41. The first half-shell 411 serves as the upper winding coil, and the second half-shell 412 serves as the lower winding coil. The outer wall of the first half-shell 411 has an upper winding region 4113, and the outer wall of the second half-shell 412 has a lower winding region 4123. A continuous coil 300 is wound within both the upper and lower winding regions 4113 and 4123. The winding density of the coil 300 in the lower winding region 4123 is greater than that in the upper winding region 4113. This structure is achieved by winding coils 300 with different numbers of turns within different winding layers. When the heating chamber is in operation, only one IH control system needs to be connected. Even if the vertical position is reversed when the cooking chamber rotates, the original second half-shell 412 portion always has a higher power, ensuring sufficient power to heat the food at all times, effectively eliminating cold surfaces and guaranteeing the quality of the stir-fry.

[0038] In this embodiment, the upper winding region 4113 covers part or all of the top wall and left and right side walls of the first half-shell 411, and the lower winding region 4123 covers part or all of the bottom wall and left and right side walls of the second half-shell 412, so that the coil 300 surrounds most of the area of ​​the first half-shell 411 and the second half-shell 412, ensuring a comprehensive heating range.

[0039] In this embodiment, the upper winding region 4113 has multiple upper winding layers 4114 arranged sequentially from the inside to the outside, and the lower winding region 4123 has multiple lower winding layers 4124 arranged sequentially from the inside to the outside. The coil 300 is continuously wound within the upper winding layers 4114 and the lower winding layers 4124, thereby using the upper winding layers 4114 and the lower winding layers 4124 to position the coil 300 and ensure the stability and uniformity of the coil 300 during the winding process. At least the inner and outer adjacent upper winding layers 4114 are interconnected, and at least the inner and outer adjacent lower winding layers 4124 are interconnected, thereby enabling the coil 300 to be wound continuously without interruption and reducing additional connections.

[0040] In this embodiment, the number of turns of the coil 300 in at least a portion of the lower winding layers 4124 is greater than the number of turns in the corresponding upper winding layers 4114, and at least a portion of the upper winding layers 4114 are not wound with coil 300. Specifically: both the upper winding layers 4114 and the lower winding layers 4124 have 17 turns, and differentiated winding densities are achieved by setting different numbers of coils 300 in different winding layers: wherein, in the 17 lower winding layers 4124 of the second half-shell 412, layers 1 to 9 and layers 12 to 16 each have 2 turns of coil 300, and layers 10, 11, and 17 each have 1 turn of coil 300; in the 17 upper winding layers 4114 of the first half-shell 411, layers 1 to 4, layers 12 to 16 each have 2 turns of coil 300, and layers 10, 11, and 17 each have 1 turn of coil 300; Layers 6, 7, 9, 11, 12, 13, 14, and 15 each have one turn of coil 300 wound around them, while layers 5, 8, 10, 16, and 17 do not have coil 300 wound around them. This results in the overall winding density and total length of coil 300 in the lower winding region 4123 being much greater than that in the upper winding region 4113. When coil 300 is connected to AC power, the induction heating power generated in the second half-shell 412 section, corresponding to the higher winding density, is greater, while the power generated in the first half-shell 411 section, corresponding to the lower winding density, is smaller. Through calculation and actual measurement, the power ratio between the upper and lower halves can be stabilized at approximately 1:4 (e.g., 250W for the first half-shell 411 section and 1000W for the second half-shell 412 section), thus satisfying the differentiated distribution of heating power.

[0041] In this embodiment, the upper winding region 4113 is provided with an upper winding avoidance region 4115 corresponding to the corner between the top wall and the side wall of the first half-shell 411, and the lower winding region 4123 is provided with a lower winding avoidance region 4125 corresponding to the corner between the bottom wall and the side wall of the second half-shell 412. Neither the upper winding avoidance region 4115 nor the lower winding avoidance region 4125 is wound with coil 300, so as to avoid the coil 300 from accumulating at the corner, causing local overheating or uneven electromagnetic field distribution.

[0042] In this embodiment, the upper winding region 4113 has a first protruding structure on the top and side walls of the first half-shell 411, and the upper winding layer 4114 is a first annular groove recessed in the first protruding structure. Further, a first corner protrusion 4116 for limiting the coil 300 from dislodging is provided within the first annular groove, and the first corner protrusion 4116 is located at the corner of the first annular groove; simultaneously, a first inner limiting protrusion 4117 for clamping the coil 300 is provided on the side wall of the first annular groove, effectively preventing the coil 300 from shifting or loosening during winding or use. Similarly, the lower winding region 4123 has a second protruding structure on the bottom and side walls of the second half-shell 412, and the lower winding layer 4124 is a second annular groove recessed in the second protruding structure. Furthermore, the second annular groove is provided with a second corner protrusion 4126 for limiting the coil 300 from coming out. The second corner protrusion 4126 is located at the corner of the second annular groove. At the same time, the groove sidewall of the second annular groove is provided with a second inner limiting protrusion 4127 for clamping the coil 300, which effectively prevents the coil 300 from shifting or loosening during winding or use.

[0043] In this embodiment, a magnetic block module is provided on the outer wall of the heating chamber 41. The magnetic block module can be used in conjunction with the electromagnetic coil 300 to increase inductance, reduce magnetic leakage, and improve heating uniformity and heating efficiency. The magnetic block module includes a first magnetic block group 46 and a second magnetic block group 47 respectively installed on different sides of the outer wall of the heating chamber 41. The area covered by the first magnetic block group 46 on the outer wall of the heating chamber is larger than the area covered by the second magnetic block group 47. The second magnetic block group 47 has a smaller coverage area and is mainly used to supplement the electromagnetic field distribution to ensure that the magnetic lines of force in the heating area are denser and more uniform. The first magnetic block group 46 includes a first magnetic block seat 461 and a plurality of first permanent magnets 462. The first magnetic block seat 461 is provided with a plurality of first magnetic block slots 4611, and at least one first permanent magnet 462 is embedded in each first magnetic block slot 4611. The second magnetic block group 47 includes a second magnetic block seat 471 and a plurality of second permanent magnets 472. The second magnetic block seat 471 is provided with a plurality of second magnetic block slots 4711, and at least one second permanent magnet 472 is embedded in each second magnetic block slot 4711. The first magnetic block seat 461 and the second magnetic block seat 471 are both fixed to the outer wall of the heating chamber 41 by bolt connection. The first permanent magnets 462 and the second permanent magnets 472 are respectively installed on the first magnetic block seat 461 and the second magnetic block seat 471, so that the first permanent magnets 462 and the second permanent magnets 472 are separated from the electromagnetic coil 300, avoiding direct contact that could cause the magnets to demagnetize due to high temperature or structural damage.

[0044] In this embodiment, the heating mounting frame 11 is provided with a plurality of heating mounting ports 111 arranged from top to bottom. The heating mounting ports 111 pass through the heating mounting frame 11 from front to back. Each heating mounting port 111 corresponds to a heating station 101. The mounting shaft passes through the heating mounting port 111 and is connected to the mounting bearing seat 43, so that the heating mounting frame 11 can better support the heating chamber 41 and maintain stable rotation.

[0045] In this embodiment, the driving device 42 includes a drive motor 421 and a transmission assembly. The drive motor 421 is mounted on the heating mounting bracket 11 via a motor mount 422. The output shaft of the drive motor 421 is connected to the mounting shaft of the heating chamber 41 via the transmission assembly to drive the heating chamber 41 to rotate around its axis. The drive motor 421 starts and stops under the command of the control module 2, and transmits power to the mounting shaft through the transmission assembly, so that the heating chamber 41 rotates smoothly under the support of the mounting bearing seat 43 and the roller assembly 12, thereby ensuring that the food container inside the heating chamber is heated evenly.

[0046] In this embodiment, the transmission assembly includes a drive pulley 423 mounted on the output shaft of the drive motor 421, a driven pulley 424 mounted on the mounting shaft, and a synchronous belt 425 that drives the drive pulley 423 and the driven pulley 424. The synchronous belt 425 efficiently transmits the power of the drive motor 421 to the mounting shaft, thereby achieving stable rotation of the heating chamber 41.

[0047] Furthermore, a positioning turntable 426 is installed on the driven pulley 424. The positioning turntable 426 rotates synchronously with the driven pulley 424. The positioning turntable 426 is correspondingly equipped with a positioning detection device 427. The positioning detection device 427 is located inside the housing 1 and installed on the heating mounting bracket 11. It is used to detect the rotation angle of the positioning turntable 426 in real time. When the positioning turntable 426 rotates to the preset position, the positioning detection device 427 outputs a signal to the control module 2. The control module 2 determines the current working status of the heating chamber based on this signal and accurately controls the drive motor 421 to stop, ensuring that the stopping position of the heating chamber 41 is accurate and consistent after each rotation.

[0048] Furthermore, the motor base 422 is provided with a tensioning elongated hole 4221, through which a motor locking bolt threadedly connected to the heating mounting bracket 11 is inserted. The heating mounting bracket 11 is threadedly fitted with a tension adjusting bolt 428 for pushing the motor base 422 to move along the direction of the tensioning elongated hole 4221. By tightening or loosening the tension adjusting bolt 428, the position of the motor base 422 is adjusted, thereby changing the center distance between the driving pulley 423 and the driven pulley 424, realizing the adjustment of the tension of the synchronous belt 425, thereby ensuring the transmission quality.

[0049] In this embodiment, the positioning detection device 427 is preferably a photoelectric switch, with its transmitting and receiving ends facing each other. The edge of the positioning turntable 426 is provided with a blocking part 4261. When the blocking part 4261 passes the photoelectric switch, a pulse signal is generated, allowing the control module 2 to know whether the heating chamber 41 has returned to the set position. Simultaneously, the synchronous belt 425 is provided with an accessory 4251, which is a trigger block integrally formed with the synchronous belt 425. The housing 1 is provided with a stroke detection device 429 for detecting and limiting the rotation amplitude of the synchronous belt 425 along a first direction. The stroke detection device 429 is mounted on the motor base 422. When the heating chamber 41 rotates to a specified angle, the accessory 4251 touches the pressing end of the stroke detection device 429 and sends a signal to the control module 2, assisting in position verification and safety protection during the rotation of the heating chamber 41. This avoids positioning deviations caused by abnormal signals from the positioning turntable 426, further improving the stability and reliability of the multi-station intelligent cooking equipment.

[0050] In this embodiment, to prevent the synchronous belt from over-rotating and causing the conductor to be pulled, a transmission limiting structure is provided. The transmission limiting structure includes a first direction limiting structure and a second direction limiting structure, which are distributed on the outer periphery of the synchronous belt 425. Further, the first direction limiting structure is provided with a first limiting surface 400a for limiting the maximum rotation amplitude of the synchronous belt 425 along the first direction. The stroke detection device 429 is a micro switch, and the pressing end of the micro switch is offset from the first limiting surface 400a. The attachment 4251 is configured to be unable to continue moving towards the stroke detection device 429 when it abuts against the first limiting surface 400a during movement along the first direction. The detection end of the stroke detection device 429 is configured to detect the attachment 4251 at least before it contacts the first limiting surface 400a. When the synchronous belt 425 rotates in the first direction, for example clockwise, the accessory 4251 moves accordingly. Before contacting the first limiting surface 400a, it enters the detection range of the stroke detection device 429. The accessory 4251 then impacts the pressing end of the stroke detection device 429, triggering it to immediately send a signal to the control module 2 of the equipment. The control module 2 then cuts off the power to the drive motor 421, thus limiting the synchronous belt 425. If an abnormality occurs and the control module 2 cannot stop the drive motor 421 in time according to the signal from the stroke detection device 429, the accessory 4251 is mechanically blocked by the first limiting surface 400a, thus preventing it from directly and violently impacting the body of the stroke detection device 429. In other words, the main function of the first-direction limiting structure is to prevent the body of the stroke detection device 429 from being violently impacted while the pressing end of the stroke detection device 429 is normally monitoring in conjunction with the accessory 4251. In addition, when the accessory 4251 collides with the first limiting surface 400a or the second limiting surface 500a, the synchronous belt 425 cannot move. At this time, the load of the drive motor 421 increases and the current rises. The control module 2 judges the load change by the current of the corresponding drive motor 421, thereby determining whether an impact has occurred and stopping the drive motor 421.

[0051] Furthermore, the second-direction limiting structure is provided with a second limiting surface 500a for limiting the maximum rotation amplitude of the synchronous belt 425 along the second direction; the travel of the accessory 4251 is limited between the first limiting surface 400a and the second limiting surface 500a. When the synchronous belt 425 rotates beyond its travel along the second direction, for example counterclockwise, it will be blocked by the second limiting surface 500a. In this way, the first-direction limiting structure and the second-direction limiting structure jointly achieve bidirectional mechanical limiting, further improving safety and reducing the probability of the heating device's wires being pulled off the solder joint.

[0052] In this embodiment, the first directional limiting structure and the second directional limiting structure are disposed on the motor base 422. The first directional limiting structure includes a first limiting seat 400 disposed on the motor base 422, a first limiting surface 400a disposed on the first limiting seat 400, and a stroke detection device 429 mounted on the first limiting seat 400, thereby facilitating position adjustment between the stroke detection device 429 and the first limiting surface 400a. Of course, in other embodiments, the stroke detection device 429 can also be mounted on the motor base 422 to achieve the same purpose. Further, the second directional limiting structure includes a second limiting seat 500 disposed on the motor base 422, and a second limiting surface 500a disposed on the second limiting seat 500.

[0053] In this embodiment, one end of the mounting ring 44 extends out of the housing 1 through the heating window. The outer periphery of the mounting ring 44 has a raised shielding ring 441 to block the heating window and prevent foreign objects from entering the housing 1. Furthermore, the diameter of the shielding ring 441 is larger than the opening size of the heating window, so that the shielding ring 441 always covers the edge of the heating window during the rotation of the mounting ring 44, effectively preventing dust, oil, and other foreign objects from entering the housing 1 and reducing contamination inside the housing 1.

[0054] In this embodiment, the exhaust assembly module is located inside the housing 1. The exhaust assembly module includes an exhaust pipe 13 for connecting the heating chamber of the heating device 4 and the interior of the housing 1, and an exhaust fan 14 for generating suction power in the exhaust pipe 13 and discharging gas outside the housing 1. Specifically, the back of the housing door 3 is provided with a smoke exhaust groove 32 corresponding to the inlet and outlet of the heating chamber. The size of the smoke exhaust groove 32 is configured to accommodate the front end of the mounting ring 44 and the blocking protrusion 441 without interfering with the rotation of the mounting ring 44 and the blocking protrusion 441. The exhaust pipe 13 is provided with an exhaust vent located inside it. The exhaust channel 131 includes an external air inlet 132 and an external air outlet 133. Both the air inlet 132 and the air outlet 133 are connected to the exhaust channel 131. The front end of the exhaust pipe 13 is fixedly connected to the inner front wall of the housing 1. The front wall of the housing 1 has a corresponding ventilation port that connects to the air inlet 132. The ventilation port penetrates the outer front wall of the housing 1. When the housing door 3 is closed, the air inlet 132 connects to the smoke exhaust groove 32 through the ventilation port. The air inlet of the exhaust fan 14 connects to the air outlet 133, and the air outlet connects to the outside of the housing 1. When oil fumes are generated in the heating chamber, the exhaust fan 14 is activated. The oil fumes enter the exhaust pipe 13 through the smoke exhaust groove 32, and are then drawn out of the housing 1 by the exhaust fan 14 from the air outlet 133, thus achieving the purpose of smoke exhaust.

[0055] In this embodiment, the exhaust pipe 13 is fixed to the housing 1 and the heating mounting bracket 11. The exhaust pipe 13 can be welded to the housing 1 and the heating mounting bracket 11, or it can be detachably installed via a threaded connection or a snap-fit ​​structure. Furthermore, the upper surface of the exhaust pipe 13 is flat, and the pipe outlet 133 penetrates the upper surface of the exhaust pipe 13. The exhaust fan 14 is installed on the upper surface of the exhaust pipe 13, and the air inlet of the exhaust fan 14 is connected to the air outlet 133, thus completing the installation of the exhaust fan 14. Further, the rear side of the housing 1 is provided with an exhaust port 108 through which the exhaust fan 14's outlet extends. After the exhaust fan 14 is installed, its outlet extends through the exhaust port 108 to the outside of the housing 1, allowing the fumes to be discharged outside the housing 1.

[0056] In this embodiment, since oil residue may remain in the exhaust channel 131 due to the oil fumes, the exhaust pipe 13 is provided with a first drain connector 134 that connects to the exhaust channel 131. The first drain connector 134 is located at the bottom of the exhaust pipe 13 and directly below the pipe outlet 133. The first drain connector 134 is connected to a drain pipe 200 for discharging oil residue outside the housing 1, which facilitates the discharge of oil residue accumulated in the exhaust channel 131.

[0057] In this embodiment, the exhaust assembly module further includes a cooling fan 15 for blowing air into the heating device 4 inside the housing 1. The cooling fan 15 is configured to blow air towards the bottom of the heating device 4, with its exhaust direction facing the bottom of the heating device 4. This upward airflow acts on the outer surface of the heating device 4, preventing heat accumulation due to prolonged operation and effectively improving heat dissipation efficiency. Furthermore, the outer wall of the exhaust pipe 13 is provided with a heat dissipation air inlet 135 communicating with the exhaust channel 131. The heat dissipation air inlet 135 is located above the exhaust end of the cooling fan 15, ensuring that the inhaled hot airflow mainly comes from the high-temperature area surrounding the heating device 4, thereby improving heat dissipation.

[0058] When the heating device 4 is working, one of the corresponding exhaust assembly modules of the heating device 4 works simultaneously. At this time, the cooling fan 15 and the exhaust fan 14 of the exhaust assembly module start working. The airflow blown out by the cooling fan 15 passes through the outer surface of the heating device 4 to dissipate heat from the heating device 4. While the exhaust fan 14 is absorbing the oil fumes inside the heating device 4, it also draws in the hot air from the heat dissipation air inlet 135 and discharges it to the outside of the box 1 along with the oil fumes, effectively reducing the temperature inside the box 1 and preventing heat accumulation from affecting the operation of other components.

[0059] In this embodiment, the heat dissipation air inlet 135 is located in the upper middle part of the outer wall of the exhaust pipe 13, thereby preventing oil from flowing back into the housing 1 due to the low position of the heat dissipation air inlet 135. Furthermore, the heat dissipation air inlet 135 is provided on both the left and right ends of the exhaust pipe 13, and the heat dissipation air inlet 135 is symmetrically arranged on the left and right sides, thereby evenly drawing in hot air from the housing 1 and improving airflow stability. Furthermore, the heat dissipation air inlet 135 is composed of multiple strip-shaped holes 1351 on the outer wall of the exhaust pipe 13, and the strip-shaped holes 1351 are arranged along the direction of oil fume flow in the exhaust pipe 13, effectively expanding the air intake area and improving heat dissipation efficiency.

[0060] In this embodiment, the housing 1 is provided with multiple heat dissipation bases 16 for mounting cooling fans 15. Some of the heat dissipation bases 16 are located on the upper end of the exhaust pipe 13, while others are located on the inner bottom wall of the housing 1. Each heat dissipation base 16 has a fan inlet 161 corresponding to the air inlet end of the cooling fan 15 and an air inlet channel 162 located below the fan inlet 161. The cooling fan 15 is mounted on the top of the heat dissipation base 16, with its air inlet end connected to the fan inlet 161. The air inlet channel 162 has at least two ends connected to the interior of the housing 1, enabling the cooling fan 15 to effectively drive airflow. Preferably, one cooling fan 15 is positioned below each heating device 4. The heat dissipation bases 16 are fixed to the upper end of the exhaust pipe 13 or the bottom of the housing 1, depending on the arrangement of the heating devices, as long as the air outlet end of the cooling fan 15 faces the bottom of the heating device 4.

[0061] In this embodiment, although most of the oil fumes generated during the heating process of the food container are discharged through the exhaust pipe 13, a small portion of the oil fumes inevitably condense into oily water droplets when the door 3 is opened, adhering to the mounting ring 44 and seeping into the cabinet 1 along the mounting ring 44. These oily water droplets flow down and accumulate under gravity after the heating chamber 41 stops rotating, dripping to the bottom of the cabinet 1. Over time, this accumulation can easily corrode the bottom structure of the cabinet 1, affecting the service life of the multi-station intelligent cooking equipment. To solve this technical problem, the cabinet 1 is provided with an oil drain trough 17 for receiving the oil sludge flowing down from the heating devices 4. Furthermore, there are multiple oil drain troughs 17 arranged from top to bottom, with the horizontally arranged heating devices 4 sharing one oil drain trough 17. This oil drain trough 17 is located below the horizontally arranged heating devices 4, thereby reducing the density of the oil drain troughs 17, simplifying the structure and facilitating later maintenance.

[0062] In this embodiment, the front side of the oil drain trough 17 is welded to the inner front wall of the housing 1, and the roller bracket 121 is provided with a concave arc position. The concave arc position matches the heating window and forms a drainage concave position for guiding oily water droplets into the oil drain trough 17.

[0063] In this embodiment, the oil drain trough 17 is provided with a second drain connector 171 and an oil drain positioning frame 172 located above the second drain connector 171. The oil drain positioning frame 172 is provided with an oil pipe positioning hole 173 corresponding to the second drain connector 171. The output end of the second drain connector 171 is connected to a second oil drain pipe 174. The second oil drain pipe 174 of the lowermost oil drain trough 17 is connected to the oil inlet of the drain pipe 200. In the two adjacent oil drain troughs 17, the lower end of the second oil drain pipe 174 of the upper oil drain trough 17 is inserted into the oil pipe positioning hole 173, so that the oil in the upper oil drain trough 17 can flow into the lower oil drain trough 17, realizing multi-stage oil guiding, and finally collecting at the lowermost second drain connector 171 and being discharged outside the box 1.

[0064] In this embodiment, the housing 1 is provided with an oil receiving tray 18 for receiving oil discharged from the sewage pipe 200. The oil receiving tray 18 is detachably installed at the bottom of the housing 1, which facilitates regular cleaning of the oil by the user. Furthermore, the bottom of the housing 1 is provided with an extension 109, which is configured to allow the oil discharge port of the sewage pipe 200 to extend out of the housing 1 and correspond to the oil receiving tray 18.

[0065] Furthermore, the bottom of the housing 1 is provided with a support structure for lifting the housing 1 and an oil pan mounting bracket 19 for mounting the oil pan 18. The oil pan mounting bracket 19 is provided with an oil pan groove, and the edge of the oil pan 18 slides in the oil pan groove, facilitating the disassembly and installation of the oil pan 18. Furthermore, the oil pan 18 is provided with an oil pan limiting groove 181, and the bottom of the housing 1 is provided with an oil pan limiting fastener 20 for fastening onto the oil pan limiting groove 181, preventing the oil pan 18 from slipping off the oil pan mounting bracket 19 due to external force during use, thereby ensuring the stability of the oil pan 18 during use.

[0066] In this embodiment, the bottom of the box 1 is provided with at least two support seats 21 arranged from front to back. The support seats 21 are used to enhance the structural strength of the box 1. The support structure, the oil pan mounting bracket 19 and the oil pan limiting fastener 20 are all fixed to the bottom of the box 1 based on the support seats 21.

[0067] Furthermore, the support structure includes multiple support rollers 22 mounted on the bottom of the support base 21. The multiple support rollers 22 are arranged in a rectangular pattern. The support rollers 22 not only lift the entire cabinet 1 off the ground, but also facilitate the movement of the multi-station intelligent cooking equipment. The support rollers 22 are preferably omnidirectional wheels with self-locking function.

[0068] Furthermore, the oil pan mounting bracket 19 includes two oil pan supports 191, which are symmetrically mounted on the bottom of the support base 21. Each oil pan support 191 has a single-sided groove for the oil pan, and the single-sided grooves of the two oil pan supports 191 together form the oil pan sliding groove, which facilitates the smooth sliding of the oil pan 18 into or out along the direction of the oil pan sliding groove, thereby improving the ease of disassembly and assembly.

[0069] Furthermore, the oil receiving tray 18 includes an oil tray body 182 and an oil tray ring edge 183 integrally formed on the upper edge of the oil tray body 182. The oil tray body 182 has an oil tray groove with an upper opening for holding oil. The left and right ends of the oil tray ring edge 183 are both embedded in the oil tray single-sided groove as sliding ends, so that the oil receiving tray 18 can be installed in conjunction with the oil tray mounting bracket 19. Furthermore, the oil tray limiting groove 181 is provided at the bottom of the oil tray ring edge 183. The oil tray limiting fastener 20 is installed on the support base 21 and located between the two oil tray supports 191, so that the oil tray limiting fastener 20 can simultaneously serve as a limiting structure to limit the insertion depth of the oil receiving tray 18 into the oil tray groove. After the oil receiving tray 18 is fully in place, it is fastened in the oil tray limiting groove 181 by the oil tray limiting fastener 20, so as to realize the positioning and installation of the oil receiving tray 18. Meanwhile, the oil pan limiting groove 181 is set around the upper edge of the oil pan body 182. The front part of the oil pan limiting groove 181 can serve as an oil pan pull groove, making it easy for the user to insert their fingers and apply force to pull the oil pan 18 out of the oil pan slide groove, thus improving the ease of operation. The rear part of the oil pan limiting groove 181 is engaged with the oil pan limiting fastener 20 to ensure the positioning and installation of the oil pan 18.

[0070] In this embodiment, the housing 1 is provided with a gas collection hood 23 that covers the air outlets of all the exhaust ports 108. The gas collection hood 23 is sealed to the outer side of the housing 1 and forms a gas collection chamber. The air outlets of all the exhaust fans 14 are connected to the gas collection chamber. The gas collection hood 23 is provided with a centralized exhaust port 231. The centralized exhaust port 231 is equipped with an oil fume purification module 24 for filtering oil fumes before discharging them, thereby reducing the impact of oil fume emissions on the outside environment and improving environmental performance. It should be noted that the exhaust fans 14 of the extraction assembly module are independent working units. The air outlets of the exhaust fans 14 of each extraction assembly module achieve centralized exhaust through the gas collection hood 23, but this does not affect the independent control function of a single module.

[0071] Furthermore, the lower end of the gas collecting hood 23 is provided with a third drain connector 232 for draining oil and water contaminants from its inner cavity. The third drain connector 232 is connected to a third drain pipe 25, and the output end of the third drain pipe 25 extends to the oil receiving tray 18, so that the oil and water contaminants in the gas collecting hood 23 are also drained into the oil receiving tray 18. In addition, the support base 21 is provided with a support through hole 211 for the third drain pipe 25 to pass through. After passing through the support through hole 211, the third drain pipe 25 is suspended above the oil receiving tray 18, so that the third drain pipe 25 is positioned and installed.

[0072] In this embodiment, the front end of the gas collection hood 23 is provided with a gas collection connecting edge for connecting to the housing 1. The gas collection connecting edge is installed and connected to the rear end of the housing 1 by bolt connection. The inner cavity opening of the gas collection hood 23 is located at the front end of the gas collection hood 23. The centralized exhaust port 231 is located at the rear end of the gas collection hood 23 and is connected to the inner cavity of the gas collection hood 23.

[0073] In this embodiment, the fume purification module 24 includes a purification housing 241 and a filter medium. The purification housing 241 has a purification chamber 2411 inside. The purification housing 241 has a purification inlet 2412 and a purification outlet 2413 that are connected to the purification chamber 2411. The filter medium is disposed in the purification chamber 2411 and located between the purification inlet 2412 and the purification outlet 2413. The purification inlet 2412 is connected to the centralized exhaust port 231 through a purification air pipe 26, so that the airflow must pass through the filter medium before it can be discharged, thereby ensuring the filtration effect.

[0074] Furthermore, the fume purification module 24 includes a filter screen 242 and an activated carbon filter layer 243 arranged in the purification chamber 2411 along the airflow direction. The filter screen 242 can be a chemical fiber filter screen, which is low in cost and has low wind resistance, and does not affect the smoke exhaust efficiency. The activated carbon filter layer 243 is preferably honeycomb activated carbon. The pore structure of honeycomb activated carbon is more regular, which will not significantly affect the smoke exhaust speed, has a larger adsorption capacity per unit volume, and a longer replacement cycle.

[0075] In this embodiment, the box 1 includes a box body 1a and a rear cover plate 1b. The rear end opening of the box body 1a is provided to facilitate the installation of various modules inside the box body 1a. The rear cover plate 1b is detachably installed on the rear end of the box body 1a by means of bolt connection, thereby closing the rear end opening of the box body 1a. The discharge port 108 is provided on the rear cover plate 1b.

[0076] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
