Description

Technical Field

[0001] This utility model relates to the field of intelligent cooking equipment technology, and specifically to an oil fume exhaust structure 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 cooking machine 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 cooking machine 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 cooking machine. At the same time, when the user opens the door to take out a lunchbox, the steam inside the heating chamber quickly condenses into water droplets at the door and heating chamber opening. These water droplets drip onto the ground around the cooking machine, polluting the surrounding environment, increasing the difficulty of cleaning, and causing inconvenience to the user. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an oil fume exhaust structure for use in intelligent cooking equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A fume extraction structure for use in intelligent cooking equipment includes a housing, at least one door, and at least one heating device. The housing has at least one heating window, each heating window corresponding to at least one heating device, and each door corresponding to at least one heating window. The door is closable and installable on the housing. The characteristic feature is that the housing is equipped with a fume extraction module for extracting fumes from the heating device and expelling them from the housing. The fume extraction module includes an exhaust pipe for connecting to the heating chamber of the heating device and an exhaust fan for generating suction power in the exhaust pipe and expelling the gas from the housing.

[0007] In this utility model, each heating device corresponds to one smoke exhaust module, and 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, and 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.

[0008] In this utility model, the air inlet of the exhaust fan is connected to the air outlet of the pipe, and the rear side of the housing is provided with an exhaust port for the exhaust fan to pass through the housing body.

[0009] In this invention, a heating mounting bracket is provided inside the box, and the exhaust pipe is fixed to the box and the heating mounting bracket.

[0010] In this utility model, the upper surface of the exhaust pipe is flat, the outlet of the pipe is provided through the upper surface of the exhaust pipe, the exhaust fan is installed on the upper surface of the exhaust pipe, and the air inlet of the exhaust fan is connected to the outlet of the pipe.

[0011] In this invention, the exhaust pipe is provided with a first drain connector that connects to the exhaust channel, and the first drain connector is located at the bottom of the exhaust pipe.

[0012] In this invention, the first drain connector is located directly below the air outlet of the pipe. The first drain connector is connected to a drain pipe for discharging oil stains outside the housing, which facilitates the discharge of oil stains accumulated in the exhaust channel.

[0013] 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.

[0014] 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.

[0015] In this invention, the exhaust fan and heating device are connected and controlled by a control module that controls the intelligent cooking equipment.

[0016] The beneficial effects of this utility model are as follows: By installing a smoke exhaust module inside the housing and directly connecting the exhaust pipe to the heating chamber of the heating device, coupled with the exhaust fan providing suction power, this utility model can quickly extract and discharge the oil fumes generated during the heating process to the outside of the housing. This reduces the retention and adhesion of oil fumes inside the heating device, thereby reducing the amount of dirt generated in the heating chamber and on the door, improving the cleanliness of the smart cooking equipment, and reducing the frequency and difficulty of subsequent cleaning for users. Furthermore, while exhausting oil fumes, the smoke exhaust module simultaneously extracts most of the steam from the heating chamber to the outside of the housing, reducing the amount of steam near the door and heating window. This lowers the probability of steam condensation and water droplets, effectively preventing water droplets from dripping and polluting the surrounding ground, reducing the extra cleaning work required from users and enhancing the ease of use of the smart cooking equipment.

[0022] Reference Figure 1-7 This embodiment discloses a fume extraction structure for use in intelligent cooking equipment. The fume extraction structure of this embodiment is applied to an intelligent cooking equipment with multiple cooking stations. It 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 windows 101 arranged horizontally and vertically, each heating window 101 corresponding to one heating device 4, and the heating device 4 is electrically connected to the control module 2. Each door 3 corresponds to one heating window 101, and the door 3 is closable and can be installed on the housing 1 to close or expose the corresponding heating window 101. The housing 1 contains a fume extraction module for extracting fumes from the heating devices 4 and expelling them outside the housing 1. The fume extraction module is connected to and controlled by the control module 2, and each heating device 4 corresponds to one fume extraction module.

[0023] 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.

[0024] In this embodiment, the smoke exhaust module includes an exhaust pipe 5 for connecting the heating chamber 40 of the heating device 4 and an exhaust fan 6 for generating suction power in the exhaust pipe 5 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 5 is provided with an exhaust channel 51 located inside it and a pipe inlet 52 and a pipe outlet 53 connected to the exhaust channel 51. The front end of the exhaust pipe 5 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 102 corresponding to the pipe inlet 52. The housing vent 102 is provided through the outer front wall of the housing 1. When the housing door 3 is closed, the pipe inlet 52 connects to the heating chamber 40 through the housing vent 102 and the smoke exhaust groove 31. The air inlet end of the exhaust fan 6 is connected to the pipe outlet 53, and the air outlet end connects to the outside of the housing 1. The exhaust fan 6 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 6 corresponding to the heating device 4 is started, so that the oil fumes in the heating chamber 40 enter the exhaust pipe 5 through the smoke exhaust groove 31, and then are drawn out to the outside of the box 1 from the exhaust outlet 53 of the pipe by the exhaust fan 6, thus achieving the purpose of smoke exhaust.

[0025] In this embodiment, a heating mounting bracket 7 is provided inside the housing 1. The exhaust pipe 5 is fixed to the housing 1 and the heating mounting bracket 7. The exhaust pipe 5 can be welded to the housing 1 and the heating mounting bracket 7, or it can be detachably installed via a threaded connection or a snap-fit ​​structure. Furthermore, the upper surface of the exhaust pipe 5 is flat, and the pipe outlet 53 penetrates through the upper surface of the exhaust pipe 5. The exhaust fan 6 is installed on the upper surface of the exhaust pipe 5, and the air inlet of the exhaust fan 6 is connected to the air outlet 53, thus completing the installation of the exhaust fan 6. Further, a discharge port 103 is provided on the rear side of the housing 1 for the exhaust fan 6 to extend out of the housing 1. After the exhaust fan 6 is installed, the exhaust fan 6 extends through the discharge port 103 to the outside of the housing 1, thereby allowing the fumes to be discharged outside the housing 1.

[0026] In this embodiment, since there may be oil residue in the exhaust channel 51, the exhaust pipe 5 is provided with a first drain connector 54 that connects to the exhaust channel 51. The first drain connector 54 is located at the bottom of the exhaust pipe 5 and directly below the pipe outlet 53. The first drain connector 54 is connected to a drain pipe 8 for discharging oil residue outside the housing 1, so as to facilitate the discharge of oil residue accumulated in the exhaust channel 51.

[0027] In this embodiment, the housing 1 is provided with an oil receiving tray 9 for receiving oil discharged from the sewage pipe 8. 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 8 to extend out of the housing 1 and correspond to the oil receiving tray 9.

[0028] 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.

[0029] In this embodiment, the bottom of the housing 1 is provided with at least two support seats 13 arranged from front to back. The support seats 13 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 13.

[0030] Furthermore, the support structure includes multiple support rollers 12 mounted on the bottom of the support base 13. The multiple support rollers 12 are arranged in a rectangular pattern. The support rollers 12 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 12 are preferably omnidirectional wheels with self-locking function.

[0031] In this embodiment, the housing 1 is provided with a gas collection hood 14 that covers the air outlets of all exhaust ports 103. The gas collection hood 14 is sealed to the outer side of the housing 1 and forms a gas collection chamber. The air outlets of all the exhaust fans 6 are connected to the gas collection chamber. The gas collection hood 14 is provided with a centralized exhaust port 141, which is used to connect to the oil fume purification module that filters the 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 6 of the smoke exhaust module are independent working units. The air outlets of the exhaust fans 6 of each smoke exhaust module achieve centralized exhaust through the gas collection hood 14, but this does not affect the independent control function of a single module.

[0032] Furthermore, the lower end of the gas collecting hood 14 is provided with a third drain connector 142 for discharging oil and water contaminants from its inner cavity. The third drain connector 142 is connected to a third drain pipe, the output end of which extends to the oil receiving tray 9, thereby allowing the oil and water contaminants in the gas collecting hood 14 to also be discharged into the oil receiving tray 9. In addition, the support base 13 is provided with a support through hole for the third drain pipe to pass through. After passing through the support through hole, the third drain pipe is suspended above the oil receiving tray 9, thereby positioning and installing the third drain pipe.

[0033] 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.
