[0069] Figure 8 yes Figure 3 Schematic diagram of the structure of the middle smoke exhaust duct 5.
[0070] See also Figures 2 to 8 As shown, in some embodiments, the cooking device may include a smoke exhaust duct 5. The smoke exhaust duct 5 may be used to exhaust the oil smoke in the cooking cavity 20. The smoke exhaust duct 5 may be arranged inside the cabinet 1, or the smoke exhaust duct 5 may be arranged inside or outside. 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.

[0071] 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.
[0072] See also Figures 2 to 8 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.
[0073] 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.

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.
[0075] 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 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.
[0078] 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 .

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.
[0080] 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.

[0082] See also Figures 3 to 9 As shown, in some embodiments, the smoke exhaust duct 5 may include a valve assembly. The valve assembly may be disposed between the air suction end of the smoke exhaust fan 6 and the smoke exhaust port 22. The valve assembly may be used to open or close the smoke exhaust duct 5. When smoke exhaust is required, the smoke exhaust duct 5 may be opened by the valve assembly. When smoke exhaust is not required, the smoke exhaust duct 5 may be closed by the valve assembly to prevent the oil 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, thereby improving the sealing and reliability of the on-off control of the smoke exhaust duct 5.

One end of the pipe member 53 away from the smoke exhaust port 22 may be connected to the air suction end of the smoke exhaust fan 6, so that the other end of the smoke exhaust passage 530 may be directly connected to the air suction end of the smoke exhaust fan 6. The smoke exhaust fan 6 may be disposed between the pipe member 53 and the smoke removal pipe 51. Therefore, the smoke exhaust fan 6 may extract the oil smoke inside the cooking cavity 20 through the pipe member 53 and the smoke exhaust port 22.
[0084] In some embodiments, the smoke outlet 22 may be provided on the top wall of the inner pot 2. The pipe member 53 may be provided above the top of the inner pot 2. The bottom end of the pipe member 53 may be directly connected to the smoke outlet 22. The top end of the pipe member 53 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 pipe member 53 from the top area thereof through the smoke outlet 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.
[0085] See also Figures 3 to 8As shown, in some embodiments, the smoke exhaust duct 5 may include a flue shell 52. The flue shell 52 may be disposed between the suction end of the smoke exhaust fan 6 and the pipe member 53. The flue shell 52 may be a shell structure with a hollow interior. The end of the pipe member 53 away from the smoke exhaust port 22 may be connected to the interior of the flue shell 52. The suction end of the smoke exhaust fan 6 may be connected to the interior of the flue shell 52. Therefore, the smoke exhaust fan 6 may extract the oil smoke inside the cooking cavity 20 through the flue shell 52, the pipe member 53 and the smoke exhaust port 22 in sequence, and make the interior of the pipe member 53 have a strong suction force.
[0086] It should be noted that in some other embodiments, the flue shell 52 may not be provided between the suction end of the smoke exhaust fan 6 and the pipe member 53. In this case, the suction end of the smoke exhaust fan 6 may be directly connected to the end of the pipe member 53 away from the smoke exhaust port 22.

[0088] See also Figures 3 to 13 As shown, in some embodiments, the valve assembly may include a valve body 54. The valve body 54 is rotatably disposed in the pipe member 53. The valve body 54 can block the smoke exhaust passage 530 in the pipe member 53. A through hole 541 may be opened in the valve body 54. When the valve body 54 rotates in the pipe member 53, the through hole 541 of the valve body 54 can rotate relative to the smoke exhaust passage 530.
[0089] See also Fig.13 As shown, when the valve body 54 rotates in the pipe member 53, the through hole 541 can be aligned and communicated with the smoke exhaust passage 530, and then the smoke exhaust passage 530 can be opened, so that the gas can pass through the through hole 541 and the smoke exhaust passage 530, and then the smoke exhaust air duct 5 is opened. At this time, the smoke exhaust fan 6 can extract the oil smoke in the cooking cavity 20 through the smoke exhaust passage 530, the through hole 541 and the smoke exhaust port 22, and then the oil smoke in the cooking cavity 20 can be discharged to the outside of the box body 1 through the smoke exhaust air duct 5.
[0090] See also Fig.11 As shown, when the valve body 54 rotates in the opposite direction in the pipe member 53, the through hole 541 may not be aligned and communicated with the smoke exhaust passage 530. At this time, the valve body 54 closes the smoke exhaust passage 530, thereby closing the smoke exhaust air duct 5.
[0091] See also Figures 9 to 13As shown, in some embodiments, the valve body 54 may be a ball valve. The through hole 541 may be provided on an axis of the ball valve. A valve cavity 5301 adapted to the ball valve may be provided in the pipe member 53. The valve cavity 5301 may be formed by a concave arrangement of the peripheral wall of the smoke exhaust passage 530 toward the peripheral side thereof. The ball valve may be rotatably embedded in the valve cavity 5301. When the through hole 541 is not connected to the smoke exhaust passage 530, the ball valve may block the smoke exhaust passage 530, thereby improving the sealing performance and reliability of the smoke exhaust passage 530.
[0092] In some embodiments, the extension direction of the through hole 541 may be arranged perpendicular to the extension direction of the rotation axis of the valve body 54. It should be noted that in other embodiments, the angle between the extension direction of the through hole 541 and the extension direction of the rotation axis of the valve body 54 may also be other angles close to being perpendicular to each other.
[0093] See also Fig.10 As shown, in some embodiments, the pipe member 53 may include a first half pipe portion 531 and a second half pipe portion 532. The first half pipe portion 531 and the second half pipe portion 532 may be arranged along the axial extension of the pipe member 53. The first half pipe portion 531 and the second half pipe portion 532 may be spliced together to form the pipe member 53. A portion of the smoke exhaust passage 530 and the valve cavity 5301 are formed on the side wall of the first half pipe portion 531 facing the second half pipe portion 532, and another portion may be formed on the side wall of the second half pipe portion 532 facing the first half pipe portion 531. When the first half pipe portion 531 and the second half pipe portion 532 are spliced together, the smoke exhaust passage 530 and the valve cavity 5301 may be formed between the first half pipe portion 531 and the second half pipe portion 532, and the valve body 54 may be rotatably clamped in the valve cavity 5301.
[0094] Fig.14 yes Fig.10 Schematic diagram of the structure of the middle valve body 54 and the control rod 55.
[0095] See also Figures 9 to 14 As shown, in some embodiments, the valve assembly may include a control rod 55. The control rod 55 may be used to drive the valve body 54 to rotate in the pipe member 53. One end of the control rod 55 may extend into the pipe member 53 and be connected to the valve body 54. The other end of the control rod 55 may be exposed and arranged outside the pipe member 53. When the control rod 55 rotates relative to the pipe member 53 with the axis of the valve body 54 as the rotation axis, the control rod 55 can drive the valve body 54 to rotate in the pipe member 53, so that the through hole 541 of the valve body 54 can be aligned and connected with the smoke exhaust channel 530 in the pipe member 53, or the through hole 541 of the valve body 54 can be not connected with the smoke exhaust channel 530 in the pipe member 53.
[0096] In some embodiments, the control rod 55 and the valve body 54 may be formed as one body. It should be noted that, in other embodiments, the control rod 55 and the valve body 54 may also be detachably connected as one body.
[0097] In some embodiments, one end of the control rod 55 connected to the valve body 54 can be arranged on the rotating shaft of the valve body 54. One end of the control rod 55 away from the valve body 54 can be arranged at intervals around the rotating shaft of the valve body 54. Therefore, the second end of the control rod 55 can be driven to rotate relative to the pipe member 53 with the axis of the valve body 54 as the rotating shaft, thereby driving the valve body 54 to rotate in the pipe member 53.
[0098] See also Figures 9 to 14 As shown, in some embodiments, the control rod 55 may include a first rod portion 551. The first rod portion 551 may be arranged on the rotating shaft of the valve body 54. The first rod portion 551 may be arranged to extend along the axis of the valve body 54. When the valve body 54 rotates in the pipe member 53, the first rod portion 551 may rotate on the axis of the valve body 54.
[0099] In some embodiments, the control rod 55 may include a second rod portion 552. One end of the second rod portion 552 may be connected to an end of the first rod portion 551 away from the valve body 54. The other end of the second rod portion 552 may be arranged at intervals around the first rod portion 551, and at intervals around the rotation axis of the valve body 54. Therefore, the second rod portion 552 of the control rod 55 may be driven to rotate relative to the pipe member 53 with the axis of the valve body 54 as the rotation axis, thereby driving the valve body 54 to rotate in the pipe member 53.
[0100] In some embodiments, the control rod 55 may include a bending portion 553. The bending portion 553 may be arranged between the first rod portion 551 and the second rod portion 552. One end of the bending portion 553 may be connected to an end of the first rod portion 551 away from the valve body 54. The other end of the bending portion 553 may be connected to the second rod portion 552. The bending portion 553 may be bent and extended toward the direction of the second rod portion 552. The first rod portion 551, the bending portion 553 and the second rod portion 552 may be connected in sequence. The first rod portion 551, the bending portion 553 and the second rod portion 552 may be integrally formed.
[0101] See also Figures 9 to 13 As shown, in some embodiments, the second rod portion 552 may be arranged in parallel and spaced apart from the first rod portion 551. It should be noted that, in some other embodiments, the extension direction of the second rod portion 552 may also form a certain angle with the extension direction of the first rod portion 551.
[0102] See also Fig.10 and Fig.14As shown, in some embodiments, a through hole 5302 may be provided in the pipe member 53. The through hole 5302 may be provided on the side wall of the pipe member 53. The through hole 5302 may be connected to the valve cavity 5301. The through hole 5302 may be arranged on an axis of the valve cavity 5301. The first rod portion 551 may be rotatably provided at the through hole 5302. Therefore, the first rod portion 551 may rotate in the through hole 5302, thereby driving the valve body 54 to rotate in the valve cavity 5301 of the pipe member 53.
[0103] In some embodiments, a positioning hole 5303 may be provided in the pipe member 53. The positioning hole 5303 may be provided on the cavity wall of the valve cavity 5301. The positioning hole 5303 may be coaxially arranged opposite to the through hole 5302. A positioning portion 542 may be convexly provided on the side of the valve body 54 away from the control rod 55. The positioning portion 542 may be rotatably disposed in the positioning hole 5303. When the first rod portion 551 rotates in the through hole 5302, the positioning hole 5303 may rotate in the positioning hole 5303, thereby allowing the valve body 54 to stably rotate in the valve cavity 5301.
[0104] See also Figures 9 to 13 As shown, in some embodiments, the valve assembly may include a control unit 56. The control unit 56 may be fixed on the supporting top plate 14. The control unit 56 may have a push rod 561. The control unit 56 may drive the push rod 561 to be pushed forward or retracted backward. When the control unit 56 controls the push rod 561 to be pushed out, the push rod 561 can abut against the second rod portion 552, and the push rod 561 can drive the second rod portion 552 to rotate relative to the pipe member 53, so that the first rod portion 551 can drive the valve body 54 to rotate in the pipe member 53, and the through hole 541 can be aligned and communicated with the smoke exhaust channel 530.
[0105] In some embodiments, the control unit 56 can be a wax motor. The wax motor has a push rod 561 and a spring (not shown). When the wax motor is powered on, the solid wax in the wax motor melts and expands due to heat, so that the push rod 561 can be pushed out. When the wax motor is powered off, the liquid wax cools, and the spring can retract the push rod 561. Using a wax motor as the control unit 56 can effectively simplify the structure of the device and reduce the cost of the device.
[0106] In some embodiments, the end of the push rod 561 of the wax motor may be sleeved with a push head 562. The push head 562 has a larger width than the push rod 561. When the push rod 561 is pushed out, the push head 562 can abut against the second rod portion 552 to drive the second rod portion 552 to rotate relative to the pipe member 53. The push head 562 can provide a larger abutment area to effectively maintain the abutment state between the push head 562 and the second rod portion 552.
[0107] See also Figures 9 to 13As shown, in some embodiments, the valve assembly may include a reset member 57. The reset member 57 may be used to reset the control rod 55. The reset member 57 may be connected to the second rod portion 552. When the control unit 56 controls the push rod 561 to be pushed out, the reset member 57 may be deformed and generate elastic force. When the control unit 56 controls the push rod 561 to be retracted, the elastic force of the reset member 57 may drive the second rod portion 552 to rotate in the opposite direction relative to the pipe member 53, so that the first rod portion 551 can drive the valve body 54 to rotate in the opposite direction in the pipe member 53, and the through hole 541 is not aligned and connected with the smoke exhaust channel 530.
[0108] In some embodiments, the reset member 57 may be a tension spring. One end of the tension spring may be connected to the second rod portion 552. The other end of the tension spring may be fixed to the support top plate 12. It should be noted that the end of the tension spring away from the second rod portion 552 may also be fixed to other positions in the box body 1. When the push rod 561 is pushed out, the push rod 561 can drive the second rod portion 552 to rotate relative to the pipe member 53 and stretch the tension spring. When the push rod 561 is retracted, the tension spring can automatically contract and drive the second rod portion 552 to rotate in the opposite direction relative to the pipe member 53.
[0109] It should be noted that, in some other embodiments, the reset member 57 may also be an elastic member such as a compression spring.
[0110] Fig.15 yes Fig.13 Middle BB section view. Fig.16 yes Fig.15 Schematic diagram of the structure in another state.
[0111] See also Figures 9 to 16 As shown, in some embodiments, the extension direction of the smoke exhaust duct 5 in the pipe member 53 can be arranged perpendicular to the axial direction of the rotating shaft of the valve body 54. Therefore, when the valve body 54 rotates in the pipe member 53, the through hole 541 of the valve body 54 can be directly connected with the smoke exhaust channel 530.
[0112] It should be noted that, in some other embodiments, the extension direction of the smoke exhaust duct 5 may also form other angles with the axial direction of the rotating shaft of the valve body 54 .
[0113] In some embodiments, when the valve body 54 rotates in the pipe member 53, the through hole 541 of the valve body 54 may also be partially connected to the smoke exhaust channel 530, such as Fig.16 Therefore, the opening degree of the smoke exhaust passage 530 can be controlled by controlling the rotation angle of the valve body 54 in the pipe member 53, thereby controlling the smoke exhaust speed of the smoke exhaust port 22.
[0114] Based on the above technical solution, the embodiment of the utility model has at least the following advantages and positive effects:
[0115] 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, and 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 valve assembly includes a pipe member 53 and a valve body 54, the pipe member 53 is arranged in the smoke exhaust duct 5, the valve body 54 is rotatably arranged in the pipe member 53, and the valve body 54 is used to close the smoke exhaust channel 530 and the smoke exhaust duct 5, thereby improving the sealing of the smoke exhaust duct 5. When the valve body 54 rotates, the through hole 541 can be used to align and communicate with the smoke exhaust channel 530, thereby opening the smoke exhaust channel 530 and the smoke exhaust duct 5, and then realizing the opening and closing of the smoke exhaust duct 5. This solution can effectively improve the reliability of the on-off control of the smoke exhaust duct 5 and improve the sealing of the on-off control of the smoke exhaust duct 5 through the valve assembly.
