Description

Technical Field

[0001] This utility model relates to the field of intelligent cooking equipment technology, and specifically to a smoke collection and purification device applied to intelligent cooking equipment. 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 intelligent cooking device typically includes a housing, a heating chamber for holding a lunchbox, 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 lunchbox and its contents, the drive device rotates the heating chamber, causing the contents to tumble and thus ensuring even heating. Additionally, the surface of the lunchbox usually has vents that allow steam to escape smoothly during heating, preventing excessive internal pressure that could cause deformation or cracking. However, this steam may carry some grease out, forming cooking fumes.

[0004] However, because this technical solution lacks an effective collection or exhaust structure for the cooking fumes, the fumes cannot be expelled from the smart cooking device in a timely manner. Instead, they gradually adhere to the inner wall of the heating chamber and the back of the door, forming grime and affecting the cleanliness of the smart cooking device. Furthermore, when users open the door to retrieve food containers, residual steam inside the heating chamber quickly condenses into water droplets at the door and heating chamber opening. These droplets drip onto the ground around the smart cooking device, polluting the surrounding environment and increasing cleaning difficulty. Additionally, if these fumes are directly discharged into the outside air, it will exacerbate air pollution in the area where the smart cooking device is located. Therefore, improvements are needed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a smoke collection and purification device for use in intelligent cooking equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A smoke collection and purification device for intelligent cooking equipment includes a housing, a control module mounted on the housing, and at least one door.

[0007] In this invention, the exhaust module includes an exhaust pipe for connecting to the heating chamber and an exhaust fan for generating suction power in the exhaust pipe and discharging gas outside the housing.

[0008] In this utility model, the back of the box door is provided with a smoke exhaust groove corresponding to the inlet and outlet of the heating chamber; the exhaust pipe is provided with an exhaust channel located inside it and a pipe inlet and a pipe outlet connected to the exhaust channel; the front wall of the box is provided with a box vent corresponding to the pipe inlet; when the box door is closed, the pipe inlet is connected to the heating chamber through the box vent and the smoke exhaust groove; the air inlet of the exhaust fan is connected to the pipe outlet, and the air outlet extends out of the box from the exhaust port.

[0009] In this utility model, the exhaust pipe is provided with a first drain connector that connects to the exhaust channel, and the first drain connector is connected to a drain pipe for discharging oil stains outside the box.

[0010] In this utility model, the box body is provided with an oil receiving tray for receiving oily wastewater discharged from the sewage pipe, and the oil receiving tray is detachably installed at the bottom of the box body.

[0011] In this utility model, the bottom of the box is provided with an extension opening, which is configured to allow the oil discharge port of the sewage pipe to extend out of the box and correspond to the oil receiving tray.

[0012] In this utility model, the lower end of the gas collecting hood is provided with a third drain connector for discharging oil, water and dirt from its inner cavity.

The filter medium is disposed in the purification chamber and located between the purification inlet and the purification outlet. The purification inlet is connected to a centralized exhaust port through a purification air pipe.

[0015] In this invention, the fume purification module includes a filter screen and an activated carbon filter layer arranged in the purification chamber along the airflow direction.

[0016] The beneficial effects of this invention are as follows: Each heating chamber inside the enclosure is equipped with an independent exhaust module. This module directly extracts cooking fumes from the chambers, preventing them from adhering to the inner walls of the heating chambers and the back of the door, thus ensuring the cleanliness of the cooking equipment and reducing subsequent cleaning workload. Simultaneously, it promptly removes steam from the chambers, preventing condensation and water droplets from polluting the surrounding environment when the user opens the door.

The door 3 is closable and can be installed on the housing 1 to close or expose the corresponding heating window 101.

[0023] Furthermore, the housing 1 is equipped with multiple exhaust modules 5 for extracting oil fumes from the heating device 4 and discharging them outside the housing 1. The housing 1 is equipped with multiple exhaust ports 102 corresponding to the multiple exhaust modules 5. The air inlet of the exhaust module 5 is connected to the heating chamber 40 of the heating device 4, and the air outlet of the exhaust module 5 passes through its corresponding exhaust port 102 and exits outside the housing 1. The housing 1 is equipped with a gas collection hood 6 covering the air outlet of all exhaust ports 102. The gas collection hood 6 is equipped with a centralized exhaust port 61, and the centralized exhaust port 61 is connected to an oil fume purification module 7 for filtering the oil fumes before discharging them, thereby reducing the impact of oil fume emissions on the outside environment and improving environmental performance.

[0024] In this embodiment, the heating window 101 is located on the front side 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 rotating the heating chamber 41. The heating chamber 41 is rotatably disposed inside the box 1, and the interior of the heating chamber 41 is a heating cavity 40 for placing the lunch box. The heating device is an electromagnetic coil 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 manner.

[0025] In this embodiment, the exhaust module 5 includes an exhaust pipe 51 for connecting to the heating chamber 40 of the heating device 4 and an exhaust fan 52 for generating suction power in the exhaust pipe 51 and discharging gas outside the housing 1. Specifically, the back of the housing door 3 is provided with a smoke exhaust groove 31 corresponding to the inlet and outlet of the heating chamber 40; the exhaust pipe 51 is provided with an exhaust channel 511 located inside it and a pipe inlet 512 and a pipe outlet 513 connected to the exhaust channel 511. The front end of the exhaust pipe 51 is fixedly connected to the inner front wall of the housing 1. The front wall of the housing 1 is provided with a housing vent 103 corresponding to the pipe inlet 512. The housing vent 103 is provided through the outer front wall of the housing 1. When the housing door 3 is closed, the pipe inlet 512 connects to the heating chamber 40 through the housing vent 103 and the smoke exhaust groove 31. The air inlet end of the exhaust fan 52 is connected to the pipe outlet 513, and the air outlet end extends out of the housing 1 from the exhaust port 102. The exhaust fan 52 is connected and controlled by the control module 2 that controls the intelligent cooking equipment. The control module 2 controls the heating device 4 corresponding to the heating window 101 to work according to the instructions. The exhaust fan 52 corresponding to the heating device 4 is activated, so that the oil fumes in the heating chamber 40 enter the exhaust pipe 51 through the exhaust groove 31, and are then drawn out to the outside of the housing 1 from the exhaust outlet 513 by the exhaust fan 52, thus achieving the purpose of smoke exhaust. It should be noted that the exhaust fan 52 of the exhaust module 5 is an independent working unit. The exhaust fan 52 of each exhaust module 5 achieves centralized exhaust through the air collection hood 6, but this does not affect the independent control function of the individual module.

[0026] In this embodiment, a heating mounting bracket 8 is provided inside the housing 1. The exhaust pipe 51 is fixed to the housing 1 and the heating mounting bracket 8. The exhaust pipe 51 can be welded to the housing 1 and the heating mounting bracket 8, or it can be detachably installed via a threaded connection or a snap-fit ​​structure. Furthermore, the upper surface of the exhaust pipe 51 is flat, and the pipe outlet 513 penetrates through the upper surface of the exhaust pipe 51. The exhaust fan 52 is installed on the upper surface of the exhaust pipe 51, and the air inlet of the exhaust fan 52 is connected to the air outlet 513, thus completing the installation of the exhaust fan 52. Furthermore, after the exhaust fan 52 is installed, the air outlet of the exhaust fan 52 extends through the exhaust port 102 to the outside of the housing 1, thereby allowing the oil fumes to be discharged outside the housing 1.

[0027] In this embodiment, since oil residue may remain in the exhaust channel 511, the exhaust pipe 51 is provided with a first drain connector 514 that connects to the exhaust channel 511. The first drain connector 514 is located at the bottom of the exhaust pipe 51 and directly below the pipe outlet 513. The first drain connector 514 is connected to a drain pipe 50 for discharging oil residue outside the housing 1, which facilitates the discharge of oil residue accumulated in the exhaust channel 511.

[0028] In this embodiment, the housing 1 is provided with an oil receiving tray 9 for receiving oil discharged from the sewage pipe 50. The oil receiving tray 9 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 104, which is configured to allow the oil discharge port of the sewage pipe 50 to extend out of the housing 1 and correspond to the oil receiving tray 9.

[0029] Furthermore, the bottom of the housing 1 is provided with a support structure for lifting the housing 1 and an oil pan mounting bracket 10 for mounting the oil pan 9. The oil pan mounting bracket 10 is provided with an oil pan groove, and the edge of the oil pan 9 slides in the oil pan groove, facilitating the disassembly and installation of the oil pan 9. Furthermore, the oil pan 9 is provided with an oil pan limiting groove 91, and the bottom of the housing 1 is provided with an oil pan limiting fastener 11 for fastening onto the oil pan limiting groove 91, preventing the oil pan 9 from slipping off the oil pan mounting bracket 10 due to external force during use, thereby ensuring the stability of the oil pan 9 during use.

[0030] In this embodiment, the bottom of the housing 1 is provided with at least two support seats 12 arranged from front to back. The support seats 12 are used to enhance the structural strength of the housing 1. The support structure, the oil pan mounting bracket 10 and the oil pan limiting fastener 11 are all fixed to the bottom of the housing 1 based on the support seats 12.

[0031] Furthermore, the support structure includes multiple support rollers 13 mounted on the bottom of the support base 12. The multiple support rollers 13 are arranged in a rectangular pattern. The support rollers 13 not only lift the entire cabinet 1 off the ground, but also facilitate the movement of the exhaust structure of the intelligent cooking equipment. The support rollers 13 are preferably omnidirectional wheels with self-locking function.

[0032] Furthermore, the lower end of the gas collecting hood 6 is provided with a third drain connector 62 for discharging oil and water contaminants from its inner cavity. The third drain connector 62 is connected to a third drain pipe 63, the output end of which extends to the oil receiving tray 9, thereby allowing the oil and water contaminants in the gas collecting hood 6 to also be discharged into the oil receiving tray 9. In addition, the support base 12 is provided with a support through hole 121 for the third drain pipe 63 to pass through. After passing through the support through hole 121, the third drain pipe 63 is suspended above the oil receiving tray 9, thereby positioning and installing the third drain pipe 63.

[0033] In this embodiment, the front end of the gas collection hood 6 is provided with a gas collection connection edge for connecting to the box body 1. The gas collection connection edge is installed and connected to the rear end of the box body 1 by bolt connection. The inner cavity opening of the gas collection hood 6 is located at the front end of the gas collection hood 6. The centralized exhaust port 61 is located at the rear end of the gas collection hood 6 and is connected to the inner cavity of the gas collection hood 6.

[0034] In this embodiment, the fume purification module 7 includes a purification housing 71 and a filter medium. The purification housing 71 has a purification chamber 711 inside. The purification housing 71 has a purification inlet 712 and a purification outlet 713 that are connected to the purification chamber 711. The filter medium is disposed in the purification chamber 711 and located between the purification inlet 712 and the purification outlet 713. The purification inlet 712 is connected to the centralized exhaust port 61 through a purification air pipe 70, thereby dividing the purification chamber 711 into an air inlet side and an air outlet side, so that the airflow must pass through the filter medium before it can be discharged, thereby ensuring the filtration effect.

[0035] Furthermore, the fume purification module 7 includes a filter screen 72 and an activated carbon filter layer 73 arranged in the purification chamber 711 along the airflow direction. The filter screen 72 can be a chemical fiber filter screen 72, which is low in cost and has low wind resistance, and does not affect the smoke exhaust efficiency. The activated carbon filter layer 73 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.

[0036] In this embodiment, the box 1 includes a box body 105 and a rear cover plate 106. The rear end opening of the box body 105 is provided to facilitate the installation of various modules inside the box body 105. The rear cover plate 106 is detachably installed on the rear end of the box body 105 by means of bolt connection, thereby closing the rear end opening of the box body 105. The discharge port 102 is provided on the rear cover plate 106.

[0037] 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.
