The first fan assembly 220 is located in the flue 30 and between the smoke extraction port 310 and the smoke exhaust port 320.

[0041] Compared with the prior art, the smokeless grill pan 1 in this embodiment of the invention has a detachable connection between the smoke extraction bracket 20 and the base 10, making it more convenient to store and carry when the smokeless grill pan 1 is not in use. Furthermore, the same smoke extraction bracket 20 can be installed on different bases 10, and different smoke extraction brackets 20 can be installed on the same base 10, thereby improving the versatility of parts and facilitating maintenance and replacement.

[0042] Specifically, the connection between the smoking bracket 20 and the base 10 can be any existing detachable connection method, including but not limited to interference fit, snap-fit, threaded connection, hinge connection, pin connection, and key connection.

[0043] Figure 1 illustrates that in this embodiment, the smoking port 310 of the smoking bracket 20 is located directly above the heating area 130 of the base 10. It can be understood that in other embodiments, the smoking port 310 can also be located in other positions, including but not limited to diagonally above or to the side of the heating area 130. In addition, the smoking bracket 20 can be provided with one or more smoking ports 310, and the specific position of the smoking port 310 can be freely set as needed.

[0044] Specifically, in this embodiment, the smoke inlet 310 is disposed on the housing 210, the smoke outlet 320 is disposed on the base 110, and the flue 30 extends from the smoke inlet 310 along the interior of the smokeless baking tray 1 in the housing 210 to the base 110, thereby forming a flue 30 between the smoke inlet 310 and the smoke outlet 320. It is understood that in other embodiments, the smoke outlet 320 may also be disposed on the housing 210, or, smoke outlets 320 may be provided on both the housing 210 and the base 10.

[0045] Referring to Figure 4, the housing 210 includes an upper housing 211 and a lower housing 212. The upper housing 211 is assembled onto the lower housing 212 to enclose and form a flue 30 or a part of a flue 30. In some possible embodiments, the upper housing 211 is detachably connected to the lower housing 212 to facilitate the disassembly of the housing 210 for cleaning accumulated grease and other waste in the flue 30. Specifically, the detachable connection methods between the upper housing 211 and the lower housing 212 include, but are not limited to, interference fit, snap-fit, threaded connection, hinge connection, pin connection, and key connection.

[0046] In this embodiment, the first fan assembly 220 is a negative pressure blower.

[0047] Referring again to Figure 4, the housing 210 is provided with a first conductive part 230 electrically connected to the first fan assembly 220, and the base 110 is provided with a second conductive part 140. When the smoking bracket 20 is installed on the base 10, the first conductive part 230 and the second conductive part 140 are electrically connected, and the base 110 can supply power to the first fan assembly 220 on the smoking bracket 20. It can be understood that in other embodiments, a rechargeable or non-rechargeable power source can also be provided on the smoking bracket 20 to supply power to the first fan assembly 220, or an external power source can be connected to the smoking bracket 20 via an interface to supply power to the first fan assembly 220.

[0048] Specifically, the first conductive part 230 is a wire 231. One end of the wire 231 is connected to the first fan assembly 220, and the other end is provided with a conductive interface for connecting to the second conductive part 140. When the smoking bracket 20 is installed on the base 10, the conductive interface of the wire 231 is electrically connected to the second conductive part 140 to realize the power supply of the base 10 to the first fan assembly 220.

[0049] Furthermore, the housing 210 is provided with a wiring channel 213 for accommodating the wire 23. A partition structure is provided between the wiring channel 213 and the flue 30 so that the wiring channel 213 and the flue 30 are not connected. When the high-temperature fumes generated during cooking are discharged through the flue 30, the high-temperature fumes will not come into contact with the wire 231, thus avoiding affecting the normal operation of the wire 231.

[0050] The smokeless baking pan 1 also includes a filter box 40, which has a mesh structure 410 for filtering and cleaning oil fumes. The base 110 has an opening 111 connecting to the flue 30. The filter box 40 is connected to one side of the base 110, and the mesh structure 410 enters the flue 30 through the opening 111 of the base 110. The filter box 40 can filter and purify oil fumes, reducing particulate matter and grease in the emitted fumes, thus reducing the impact on users and minimizing pollution. Of course, in other embodiments, the opening 111 can be located on the housing 210, and the filter box 40 can be correspondingly installed on the housing 210; alternatively, the filter box 40 can be omitted.

[0051] In this embodiment, the filter box 40 is detachably connected to the base 110, allowing for better replacement of the worn mesh structure 410. Specifically, at least a portion of the mesh structure 410 is composed of activated carbon. Furthermore, the mesh structure 410 may also include other adsorption materials, including but not limited to porous membranes and metal-organic framework materials.

[0052] Specifically, the flue 30 includes a main flue 330 and a first branch flue 340 and a second branch flue 350 located in the filter box 40. The base 110 is provided with two exhaust ports 320. One end of each of the first branch flue 340 and the second branch flue 350 is connected to the main flue 330, and the other end is connected to the corresponding exhaust port 320. Both the first branch flue 340 and the second branch flue 350 are provided with a mesh structure 410. This arrangement can divert the oil fumes in the flue 30, further improving the filtration and purification effect.

[0053] Referring to Figures 4 and 5, Figure 5 illustrates the flow direction of fumes within the flue 30. Due to the presence of the first branch flue 340 and the second branch flue 350, the flue 30 can be divided into two branches within the filter box 40. One branch carries fumes along paths abcde and is discharged into the air through the corresponding exhaust port 320. The other branch carries fumes along paths abcfg and is discharged into the air through the corresponding exhaust port 320.

[0054] Referring to Figures 6 and 7, which illustrate the air outlet diagram of the air duct 50, the base 110 is equipped with a second fan assembly 112 and an air duct 50. One end of the air duct 50 is provided with an air inlet 510, and the other end is provided with an air outlet 520. The air outlet 520 faces the heating area 130 of the base 10. The second fan assembly 112 is located inside the air duct 50 and between the air inlet 510 and the air outlet 520. The second fan assembly 112 inside the air duct 50 is used to draw outside air into the air duct 50 and blow it along the air duct 50 from the air outlet 520 to the heating area 130, so that the oil fumes generated in the heating area 130 converge towards the smoke extraction port 310, further improving the smoke extraction efficiency and preventing the oil fumes from spreading to the surroundings and affecting the user's cooking.

[0055] Referring to Figure 8, which shows the wind direction within the air duct 50.

[0056] The air duct 50 includes a main air duct 530 and three branch air ducts 540. The air inlet 510 and the second fan assembly 112 are both located in the main air duct 530. One end of each of the three branch air ducts 540 is connected to the main air duct 530, and the other end is connected to the corresponding air outlet 520. Figure 8 shows that the air outlets 520 connected by the three branch air ducts 540 are located on opposite sides of the heating area 130 and opposite to the smoke exhaust port 320, so that the oil fumes in the heating area 130 are blown in three directions, which helps to concentrate the oil fumes at the smoke exhaust port 310.

[0057] Due to the existence of the three branch air ducts 540, the air duct 50 is divided into three branches within the seat body 110. The first branch is where the air flows along path a. ， -b ， -c ， The airflow then flows along the corresponding air outlet 520 to the heating area 130; the second path is the airflow along path a. ， -d ， -e ， The air then flows along the corresponding air outlet 520 to the heating area 130, and the third is the airflow along path a. ， -f ， -g ， The air flows and then flows along the corresponding air outlet 520 to the heating area 130.

[0058] Referring to Figures 3 and 8, Figure 8 shows the structural diagram of the bottom of the base 110.

[0059] Furthermore, Figure 8 illustrates that multiple air outlets 520 are arranged side by side on each side of the heating area 130. These multiple air outlets 520 can cover a larger area and ensure more uniform airflow. In this case, each branch air duct 540 provides airflow to the multiple air outlets 520 on one side of the heating area 130. It is understood that in other embodiments, different numbers and positions of air ducts 50 and air outlets 520 can be used. For example, in some possible embodiments, two branch air ducts 540 are provided, and air outlets 520 are provided on both sides of the heating area 130.

[0060] Figure 3 illustrates that the base 10 also includes a grill rack 150 for placing cooking materials. The grill rack 150 is mounted on the base 110 and located on one side of the heating assembly 120. The grill rack 150 is detachably connected to the base 110. The detachable connection of the grill rack 150 facilitates removal for cleaning and replacement of damaged parts. Specifically, handles 151 for easy lifting are provided on opposite sides of the grill rack 150.

[0061] The base 10 also includes an oil collection box 160, which is located on the side of the base 110 away from the grill 150. The grill 150 has an oil drain hole 152, and the base 110 has a through hole 113. The two ends of the through hole 113 are respectively connected to the oil drain hole 152 and the oil collection box 160. Liquid oil and other waste generated during cooking can enter the through hole 113 through the oil drain hole 152 and finally fall into the oil collection box 160.

[0062] Specifically, the oil collection box 160 is detachably connected to the base 110, which makes it easier to clean the oil collection box 160.

[0063] The base 10 also includes buttons 170, at least one of which is a power button. Specifically, in this embodiment, there are multiple buttons 170. In addition to the power button for controlling the power supply, there are also buttons 170 for controlling the first fan assembly 220 and the second fan assembly 112, or buttons 170 for controlling the power of the first fan assembly and / or the second fan assembly 112, but this is not a limitation. It is understood that in other embodiments, the buttons 170 may also be located on the smoking bracket 20.

[0064] Figure 3 illustrates that the bottom of the base 110 is provided with heat dissipation holes 180 for heat dissipation. There are multiple heat dissipation holes 180. In particular, the base 110 has dedicated heat dissipation holes 180 on the side close to the circuit board (PCB). It can be understood that in other embodiments, different numbers and shapes of heat dissipation holes 180 can be provided as needed.

[0065] Specifically, the second fan assembly 112 is a negative pressure blower, and the heating assembly 120 is a heating tube. The heating tube is curved, which can cover more heating areas 130, and the food being cooked is heated more evenly. It is understood that in other embodiments, the heating assembly 120 can also be set as other heating devices, such as heating wires, heating plates, etc. The present invention does not limit the specific shape and number of heating assemblies.

[0066] In one embodiment, the smokeless baking pan 1 is equipped with filters at both the smoke inlet 310 and the air inlet 510 to prevent large particles from entering the smoke duct 30 or the air duct 50 and to avoid clogging the smoke duct 30 or the air duct 50.
