[0053] It should be noted that, in other embodiments, the heat dissipation fan 31 may also be arranged at other positions of the heat dissipation air duct 3. The heat dissipation fan 31 may also be other types of fans.

[0054] See also Figures 2 to 5 As shown, in some embodiments, the heat dissipation duct 3 can be provided in the top area of ​​the box body 1. The heat dissipation duct 3 can be provided in the upper area of ​​the inner liner 2. In this case, the air inlet end of the heat dissipation duct 3 can be located on the back side of the air outlet end thereof. The heat dissipation duct 3 can be extended and arranged along the front and rear direction of the box body 1. The heat dissipation duct 3 discharges the heat in the cavity to the front space of the box body 1.

One end of the smoke exhaust duct 5 may be connected to the cooking cavity 20, and the other end of the smoke exhaust duct 5 may be connected to the outside of the cabinet 1. Therefore, the oil smoke in the cooking cavity 20 may be discharged to the external space of the cabinet 1 through the smoke exhaust duct 5.

[0066] In some embodiments, a smoke exhaust port 22 connected to the cooking cavity 20 may be provided on the outer wall of the inner pot 2. One end of the smoke exhaust duct 5 may be connected to the smoke exhaust port 22, so that the oil smoke in the cooking cavity 20 can be discharged to the external space of the box body 1 through the smoke exhaust port 22 and the smoke exhaust duct 5 in sequence.

[0067] See also Figures 2 to 7 As shown, in some embodiments, one end of the smoke exhaust duct 5 away from the smoke exhaust port 22 can be connected to the air guide cover 32, so that the smoke exhaust duct 5 can be connected to the heat dissipation duct 3. Therefore, the oil smoke in the cooking cavity 20 can be discharged to the external space of the box body 1 through the smoke exhaust port 22, the smoke exhaust duct 5, and the heat dissipation duct 3 in sequence.

[0068] It should be noted that when installing the smoke exhaust duct 5, it is only necessary to connect the two ends of the smoke exhaust duct 5 to the smoke exhaust port 22 and the air guide cover 32. This structural solution can reduce the changes to the internal structure of the box 1 when adding the smoke exhaust duct 5 by using the heat dissipation duct 3 to discharge oil smoke, which is conducive to simplifying the structure of the cooking device and reducing costs.

[0069] See also Figures 3 to 7 As shown, in some embodiments, a smoke exhaust fan 6 may be provided in the smoke exhaust duct 5. The smoke exhaust fan 6 may be used to provide wind power. The air suction side of the smoke exhaust fan 6 may be connected to the smoke exhaust port 22 of the inner pot 2.

Therefore, when the smoke exhaust fan 6 is running, the smoke exhaust fan 6 may extract the oil smoke in the cooking cavity 20 through the smoke exhaust port 22, and discharge the extracted oil smoke into the external space of the cabinet 1 through the smoke exhaust duct 5.

[0070] In some embodiments, the smoke exhaust fan 6 may be a turbo fan, which can improve the heat dissipation efficiency of the smoke exhaust duct 5, and is conducive to the rapid exhaust of oil smoke and heat dissipation and cooling of the cooking cavity 20.

The smoke removal pipe 51 may filter and purify the oil smoke entering the smoke exhaust duct 5 through the smoke removal module. The smoke removal pipe 51 may be provided at the air outlet end of the smoke exhaust fan 6. The air outlet end of the smoke exhaust fan 6 may be connected to one end of the smoke removal pipe 51. The end of the smoke removal pipe 51 away from the smoke exhaust fan 6 may be connected to the heat dissipation duct 3, and further may be connected to the external space of the housing 1. Therefore, the smoke exhaust fan 6 may extract the oil smoke in the cooking cavity 20 through the smoke exhaust port 22, and transport the extracted oil smoke into the smoke removal pipe 51, and after filtering and purifying through the smoke removal module in the smoke removal pipe 51, the oil smoke is discharged to the outside of the housing 1 through the heat dissipation duct 3.

[0073] It should be noted that, in other embodiments, the end of the smoke removal pipe 51 away from the smoke exhaust fan 6 may also be directly connected to the external space of the box body 1 .

[0074] See also Figures 3 to 7 As shown, in some embodiments, the smoke exhaust duct 5 may include a first connecting pipe 511. The first connecting pipe 511 may be provided between the smoke removal duct 51 and the heat dissipation duct 3. One end of the first connecting pipe 511 may be connected to an end of the smoke removal duct 51 away from the smoke exhaust fan 6, so that the first connecting pipe 511 can be connected to the inside of the smoke removal duct 51. The other end of the first connecting pipe 511 may be connected to the air guide cover 32, so that the first connecting pipe 511 can be connected to the heat dissipation duct 3. Therefore, the smoke exhaust duct 5 can be connected to the heat dissipation duct 3 through the first connecting pipe 511, and the oil smoke extracted by the smoke exhaust fan 6 is transported into the heat dissipation duct 3 through the smoke removal duct 51.

[0075] In some embodiments, the smoke exhaust duct 5 may include a second connecting pipe 512. The second connecting pipe 512 may be disposed between the smoke removal duct 51 and the air outlet end of the smoke exhaust fan 6. One end of the second connecting pipe 512 may be connected to the air outlet end of the smoke exhaust fan 6. The other end of the second connecting pipe 512 may be connected to an end of the smoke removal duct 51 away from the heat dissipation duct 3. Therefore, the oil smoke extracted by the smoke exhaust fan 6 can be transported into the smoke removal duct 51 through the second connecting pipe 512.

The smoke exhaust pipe 52 may be arranged outside the inner pot 2. The smoke exhaust air may be arranged between the smoke exhaust pipe 52 and the smoke removal pipe 51. One end of the smoke exhaust pipe 52 may be directly connected to the smoke exhaust port 22 on the outer wall of the inner pot 2. One end of the smoke exhaust pipe 52 away from the smoke exhaust port 22 may be connected to the suction end of the smoke exhaust fan 6. Therefore, the smoke exhaust fan 6 may extract the oil smoke inside the cooking cavity 20 through the smoke exhaust port 22 and the smoke exhaust pipe 52.

[0078] In some embodiments, the smoke exhaust port 22 may be disposed on the top wall of the inner pot 2. The smoke exhaust pipe 52 may be disposed above the top of the inner pot 2. The bottom end of the smoke exhaust pipe 52 may be directly connected to the smoke exhaust port 22. The top end of the smoke exhaust pipe 52 may be connected to the air suction end of the smoke exhaust fan 6. Therefore, when the smoke exhaust fan 6 is running, the oil smoke inside the cooking cavity 20 may smoothly enter the smoke exhaust pipe 52 from the top area thereof through the smoke exhaust port 22, and then be discharged to the external space of the box body 1 through the smoke removal pipe 51, thereby improving the oil smoke exhaust efficiency.

[0079] See also Figure 6 As shown, in some embodiments, a stop ring 23 may be convexly provided on the outer wall of the inner liner 2. The stop ring 23 may be annular and arranged around the circumference of the smoke exhaust port 22.

When the smoke exhaust pipe 52 is installed on the outer wall of the inner liner 2, the end of the smoke exhaust pipe 52 close to the smoke exhaust port 22 may be sleeved on the outer circumference of the stop ring 23, and then the smoke exhaust pipe 52 is positioned and fixed by the stop ring 23.

[0080] See also Figures 3 to 8 As shown, in some embodiments, a flue shell 53 may be provided between the suction end of the smoke exhaust fan 6 and the smoke exhaust pipe 52.

The suction end of the smoke exhaust fan 6 may be connected to the interior of the flue shell 53. Therefore, the smoke exhaust fan 6 may extract the oil smoke inside the cooking cavity 20 through the flue shell 53, the smoke exhaust pipe 52 and the smoke exhaust port 22 in sequence, and make the interior of the smoke exhaust pipe 52 have a strong suction force.

[0081] It should be noted that in some other embodiments, the flue shell 53 may not be provided between the suction end of the smoke exhaust fan 6 and the smoke exhaust pipe 52. In this case, the suction end of the smoke exhaust fan 6 may be directly connected to the end of the smoke exhaust pipe 52 away from the smoke exhaust port 22.

The on-off control component 7 is movably provided in the smoke exhaust duct 5. The on-off control component 7 may be used to automatically block the smoke exhaust duct 5. Therefore, the on-off control component 7 may be used to perform on-off control of smoke exhaust in the cooking cavity 20. When smoke exhaust is not required, the smoke exhaust duct 5 may be automatically closed by the on-off control component 7 to prevent the smoke and hot air in the cooking cavity 20 from being discharged to the outside of the cabinet 1 through the smoke exhaust duct 5.

[0084] In some embodiments, a switch opening 520 may be provided in the smoke exhaust duct 5. The switch control component 7 may be provided at the switch opening 520. The switch control component 7 may be used to automatically block the switch opening 520, thereby automatically closing the smoke exhaust duct 5.

[0085] In some embodiments, the on-off opening 520 may be disposed in the smoke exhaust pipe 52. The on-off control component 7 may be movably disposed in the smoke exhaust pipe 52. The on-off control component 7 can close the smoke exhaust pipe 52 by automatically blocking the on-off opening 520, thereby closing the smoke exhaust air duct 5.

[0086] It should be noted that, in some other embodiments, the on-off port 520 may also be arranged in other sections of the smoke exhaust duct 5 , and thus the on-off control component 7 may also be arranged in other areas of the smoke exhaust duct 5 .

[0087] See also Figures 3 to 10 As shown, in some embodiments, the cooking device may include an on-off control motor 8. The output end of the on-off control motor 8 may be arranged toward the on-off port 520 and the on-off control motor 8. When the on-off control motor 8 is running, the output end of the on-off control motor 8 can move toward the on-off control component 7, so that the output end of the on-off control motor 8 can be offset against the on-off control component 7, driving the on-off control component 7 to separate from the on-off port 520, opening the on-off port 520, and then opening the smoke exhaust pipe 52 and the smoke exhaust air duct 5.

[0088] In some embodiments, the on-off control assembly 7 is rotatably disposed in the smoke exhaust pipe 52. When the on-off control motor 8 is running and the output end of the on-off control motor 8 abuts against the on-off control assembly 7, the output end of the on-off control motor 8 can drive the on-off control assembly 7 to rotate and open the on-off port 520, thereby opening the smoke exhaust pipe 52 and the smoke exhaust duct 5.

[0089] In some embodiments, the output end of the on-off control motor 8 can move in a direction away from the on-off control component 7, so that the output end of the on-off control motor 8 can be separated from the on-off control component 7, and then the on-off control component 7 can automatically re-seal the on-off port 520 and close the smoke exhaust pipe 52 and the smoke exhaust duct 5.

[0090] See also Figures 8 to 14 As shown, in some embodiments, the on-off control assembly 7 may include a valve cover 71. The valve cover 71 may be movably arranged in the smoke exhaust pipe 52. The size of the valve cover 71 may be larger than the on-off opening 520. The valve cover 71 may automatically block the on-off opening 520, thereby automatically closing the smoke exhaust pipe 52 and the smoke exhaust air duct 5. When the output end of the on-off control motor 8 abuts against the valve cover 71, the output end of the on-off control motor 8 can drive the valve cover 71 to separate from the on-off opening 520, open the on-off opening 520, and then open the smoke exhaust pipe 52 and the smoke exhaust air duct 5.

[0091] In some embodiments, a protective head 81 may be sleeved on the output end of the on-off control motor 8. The protective head 81 may be sealingly sleeved on the output end of the on-off control motor 8. The protective head 81 may be made of a high temperature resistant material. The output end of the on-off control motor 8 may abut against the valve cover 71 through the protective head 81, driving the valve cover 71 to open the on-off port 520. When the protective head 81 drives the valve cover 71 to open the on-off port 520, the protective head 81 may protect the output end of the on-off control motor 8 from the high temperature of the oil smoke flowing through the on-off port 520. In some embodiments, the on-off control assembly 7 may include a rotating frame 72. The rotating frame 72 may be rotatably disposed in the exhaust pipe 52. One end of the rotating frame 72 may be rotatably connected to the inner wall of the exhaust pipe 52. The other end of the rotating frame 72 may be connected to the valve cover 71. The rotating frame 72 can rotate toward the on-off opening 520 to drive the valve cover 71 to block the on-off opening 520 , thereby closing the smoke exhaust pipe 52 and the smoke exhaust air duct 5 .

[0092] In some embodiments, one end of the rotating frame 72 may be integrally connected to the valve cover 71 by bonding, welding, etc. In some other embodiments, one end of the rotating frame 72 may also be detachably connected to the valve cover 71 as one body.

[0093] In some embodiments, the on-off control assembly 7 may include a fixing frame 73. The fixing frame 73 may be fixed to the inner wall of the smoke exhaust pipe 52. One end of the rotating frame 72 is rotatably connected to the fixing frame 73. The rotating frame 72 may be fixed in the smoke exhaust pipe 52 through the fixing frame 73. The rotating frame 72 may rotate relative to the fixing frame 73 and then rotate in the smoke exhaust pipe 52.

[0094] In some embodiments, the fixed frame 73 may be provided with a rotating shaft 731. One end of the rotating frame 72 may be rotatably connected to the rotating shaft 731. The rotating frame 72 can rotate relative to the rotating shaft 731, and then rotate relative to the fixed frame 73.

[0095] In some embodiments, the fixing frame 73 can be fixed in the smoke exhaust pipe 52 by bonding, welding, etc. In some other embodiments, one end of the rotating frame 72 can also be detachably connected to the inner wall of the smoke exhaust pipe 52.

[0096] See also Figures 8 to 14 As shown, in some embodiments, the on-off control assembly 7 may include an elastic member (not shown in the figure). The elastic member may abut against the rotating frame 72. The elastic member can drive the rotating frame 72 to rotate in the direction of the on-off opening 520, drive the valve cover 71 to automatically block the on-off opening 520, and then automatically close the smoke exhaust pipe 52 and the smoke exhaust air duct 5. When the output end of the on-off control motor 8 abuts against the valve cover 71, the output end of the on-off control motor 8 can drive the rotating frame 72 to overcome the elastic force of the elastic member and rotate in the opposite direction, so that the valve cover 71 is separated from the on-off opening 520, the on-off opening 520 is opened, and then the smoke exhaust pipe 52 and the smoke exhaust air duct 5 are opened.

[0097] In some embodiments, the elastic member may be a torsion spring. The torsion spring may be sleeved on the rotating shaft 731. One elastic arm of the torsion spring may abut against the fixed frame 73. Another elastic arm of the torsion spring may abut against the rotating frame 72. The torsional elastic force of the torsion spring may drive the rotating frame 72 to rotate relative to the fixed frame 73, and drive the valve cover 71 to automatically block the on-off port 520.

[0098] See also Figure 12 to Figure 14 As shown, in some embodiments, a limiting rib 521 may be convexly provided on the inner wall of the smoke exhaust pipe 52. The limiting rib 521 may be annular. The limiting rib 521 may be circumferentially arranged on the inner wall of the smoke exhaust pipe 52. The on-off opening 520 may be formed at the center of the limiting rib 521. When the valve cover 71 is blocked at the on-off opening 520, the peripheral edge of the valve cover 71 can be sealed with the limiting rib 521, thereby sealing the on-off opening 520.

[0099] See also Figure 12 to Figure 14As shown, in some embodiments, the valve cover 71 includes a protrusion 711 and a sealing rib 712 that are connected in one piece. The contour shape of the protrusion 711 can be consistent with the contour shape of the on-off opening 520. The sealing rib 712 can be circumferentially arranged at the peripheral edge of the protrusion 711. When the valve cover 71 is sealed at the on-off opening 520, the protrusion 711 can be penetrated and sealed in the on-off opening 520, and the sealing rib 712 can be sealed with the limiting rib 521, thereby sealing the on-off opening 520.

[0100] In some embodiments, the limiting rib 521 may be provided at one end of the smoke exhaust pipe 52 away from the smoke exhaust port 22. When the smoke exhaust port 22 and the smoke exhaust pipe 52 are arranged at the top of the inner tank 2, the limiting rib 521 may be provided at the top end of the smoke exhaust pipe 52. When the valve cover 71 is blocked at the on-off port 520, the protrusion 711 may protrude out of the on-off port 520, and the protrusion 711 may be exposed on the end surface of the smoke exhaust pipe 52, so that the output end of the on-off control motor 8 may abut against the protrusion 711.

[0101] In some embodiments, the on-off control motor 8 can be fixed above the top of the flue shell 53 by a mounting bracket 82. The output end of the on-off control motor 8 can be arranged vertically opposite to the exhaust pipe 52. The output end of the on-off control motor 8 can extend into the flue shell 53, and can extend into the on-off port 520 in the exhaust pipe 52, and abut against the valve cover 71.

[0102] Based on the above technical solution, the embodiment of the utility model has at least the following advantages and positive effects:

[0103] In the cooking device of the embodiment of the utility model, a smoke exhaust port 22 is provided on the outer wall of the inner pot 2. The smoke exhaust duct 5 cooperates with the smoke exhaust fan 6 to extract the oil smoke in the cooking cavity 20 through the smoke exhaust port 22, and discharge the oil smoke to the outside of the box body 1 through the smoke exhaust duct 5. The on-off control component 7 is rotatably arranged inside the smoke exhaust duct 5, and the smoke exhaust duct 5 is automatically blocked by the on-off control component 7 to improve the sealing of the smoke exhaust duct 5. The output end of the on-off control motor 8 is used to counteract the on-off control component 7, so as to drive the on-off control component 7 to rotate and open the smoke exhaust duct 5, thereby realizing the opening and closing of the smoke exhaust duct 5. The on-off control motor 8 is only responsible for opening the on-off control component 7, which increases the reliability and service life of the motor, thereby effectively improving the reliability of the on-off control of the smoke exhaust duct 5 and improving the sealing of the on-off control of the smoke exhaust duct 5.
