The heat dissipation fan 31 may be a cross-flow air supply fan to increase the wind force at the air inlet end of the heat dissipation air duct 3, improve the efficiency of extracting air in the cavity, and further improve the heat dissipation efficiency in the cavity.

[0054] 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.

[0055] 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.

Therefore, the heat dissipation duct 3 will not affect the opening or closing of the cabinet door 11. When the cabinet door 11 is closed, the heat dissipation performance of the heat dissipation duct 3 will not be affected.

[0057] See also Figures 2 to 5 As shown, in some embodiments, a supporting top plate 12 may be provided in the box body 1. The supporting top plate 12 may be provided above the inner liner 2 at intervals. The heat dissipation duct 3 may be arranged above the top of the supporting top plate 12.

[0062] See also Figure 5 As shown, in some embodiments, an exhaust port 21 may be provided at the top of the inner pot 2. The exhaust port 21 may be provided on the top surface of the cooking cavity 20. The cooking cavity 20 can be connected to the heat dissipation duct 3 through the exhaust port 21. Therefore, when the heat dissipation fan 31 is running, a negative pressure may be formed in the heat dissipation duct 3, so that the air in the cooking cavity 20 may enter the heat dissipation duct 3 through the exhaust port 21 and be discharged to the outside of the box body 1, thereby realizing the heat dissipation function of the cooking cavity 20.

[0063] It should be noted that when the gas pressure in the cooking cavity 20 is too high, the gas may also enter the heat dissipation duct 3 through the exhaust port 21 and be discharged to the outside of the box body 1 through the heat dissipation duct 3 .

[0066] See also Figures 2 to 7 As shown, in some embodiments, the cooking device may include a smoke exhaust duct 5, which 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, and the smoke exhaust duct 5 may be arranged outside the inner pot 2. 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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. The air outlet end of the smoke exhaust fan 6 may be connected to the external space of the cabinet 1. 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.

[0071] 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.

[0072] It should be noted that in other embodiments, the smoke exhaust fan 6 may also be other types of fans.

[0073] See also Figures 2 to 7As shown, in some embodiments, the smoke exhaust duct 5 may include a smoke removal pipe 51. A smoke removal module (not shown in the figure) may be provided inside the smoke removal pipe 51. 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.

[0074] 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 .

[0075] 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.

[0076] 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.

[0077] Figure 8 yes Figure 7 A schematic structural diagram of the middle smoke exhaust pipe 52.

[0078] See also Figures 3 to 8As shown, in some embodiments, the smoke exhaust duct 5 may include a smoke exhaust pipe 52. The smoke exhaust pipe 52 may be arranged inside the housing 1. The smoke exhaust pipe 52 may be arranged outside the inner pot 2. The smoke exhaust fan 6 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 air 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.

[0079] 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.

[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 flue shell 53 may be a shell structure with a hollow interior. The end of the smoke exhaust pipe 52 away from the smoke exhaust port 22 may be connected to the interior of the flue shell 53. 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.

[0083] See also Figures 3 to 12As shown, in some embodiments, a flip assembly 7 may be provided in the smoke exhaust duct 5, and the flip assembly 7 is used to automatically close the smoke exhaust duct 5. Therefore, the flip assembly 7 can be used to control the smoke exhaust in the cooking cavity 20. When smoke exhaust is not needed, the smoke exhaust duct 5 can be automatically closed by the flip assembly 7 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.

[0084] In some embodiments, when the smoke exhaust fan 6 is running, the wind force of the smoke exhaust fan 6 can drive the flip assembly 7 to rotate and open the smoke exhaust duct 5, so that the exhaust smoke in the cooking cavity 20 can be extracted by the smoke exhaust fan 6 and discharged to the outside of the box 1 through the smoke exhaust duct 5.

[0085] In some embodiments, the flip assembly 7 may include a flip plate 71. The flip plate 71 is rotatably disposed in the smoke exhaust duct 5. When the smoke exhaust fan 6 is running, the wind force of the smoke exhaust fan 6 can drive the flip plate 71 to rotate and open the smoke exhaust duct 5.

[0089] See also Figures 6 to 13 As shown, in some embodiments, the flip assembly 7 may include a rotating shaft 72. The rotating shaft 72 may be disposed in the smoke exhaust pipe 52. The flip plate 71 may be rotatably connected to the rotating shaft 72. The flip plate 71 may rotate inside the smoke exhaust pipe 52 with the rotating shaft 72 as an axis. When the smoke exhaust fan 6 is running, the wind force of the smoke exhaust fan 6 may drive the flip plate 71 to rotate toward a side away from the smoke exhaust port 22, thereby opening the smoke exhaust pipe 52. When the smoke exhaust fan 6 stops, the flip plate 71 may rotate in the opposite direction, toward a side close to the smoke exhaust port 22, thereby closing the smoke exhaust pipe 52.

[0090] In some embodiments, a rotating shaft portion 521 may be protruded from the outer wall of the smoke exhaust pipe 52. The end of the rotating shaft 72 may be passed through and fixed in the rotating shaft portion 521, thereby fixing the rotating shaft 72 in the smoke exhaust pipe 52.

[0101] See also Figures 6 to 15 As shown, in some embodiments, the elastic member 73 may be a torsion spring. The torsion spring may be sleeved on the rotating shaft 72. An elastic arm 731 may be formed at each end of the torsion spring. One elastic arm 731 of the torsion spring may abut against the first flip plate 711. Another elastic arm 731 of the torsion spring may abut against the second flip plate 712. By utilizing the elastic force of the torsion spring, the torsion spring may simultaneously drive the first flip plate 711 and the second flip plate 712 to rotate toward the direction close to the smoke exhaust port 22, so that the first flip plate 711 and the second flip plate 712 can be combined to close the smoke exhaust port 22 and the smoke exhaust pipe 52, thereby closing the smoke exhaust duct 5.

[0102] It should be noted that, in some other embodiments, two elastic members 73 may be provided. One elastic member 73 is respectively against the first flip plate 711, thereby driving the first flip plate 711 to rotate toward the direction close to the smoke exhaust port 22, so that the first flip plate 711 can automatically close a part of the smoke exhaust port 22 and the smoke exhaust pipe 52. Another elastic member 73 can be against the second flip plate 712, thereby driving the second flip plate 712 to rotate toward the direction close to the smoke exhaust port 22, so that the second flip plate 712 can automatically close another part of the smoke exhaust port 22 and the smoke exhaust pipe 52.

[0103] See also Figures 9 to 15 As shown, in some embodiments, the first flip plate 711 may include a first curved plate 7111 and a first extension plate 7112 connected in one piece.

The second extension plate 7122 may be extended from one end of the second curved plate 7121 toward the direction of the first curved plate 7111. The first extension plate 7112 and the second extension plate 7122 may be arranged in a staggered manner, so that the first extension plate 7112 and the second extension plate 7122 can be arranged relative to each other along the axial direction of the rotating shaft 72.

[0104] When the first flip plate 711 and the second flip plate 712 are combined to close the smoke outlet 22 and the smoke exhaust pipe 52, the first curved plate 7111 and the second curved plate 7121 can be arranged opposite to each other. The first curved plate 7111 and the second curved plate 7121 can be combined to close the interval area between the first curved plate 7111 and the second curved plate 7121.

[0105] See also Figures 9 to 15 As shown, in some embodiments, the first flip plate 711 may include a first connecting plate 7113. The first connecting plate 7113 may be arranged by bending and extending one end of the first extension plate 7112 close to the second extension plate 7122 toward the direction of the rotation axis 72. The first connecting plate 7113 may be rotatably connected to the rotation axis 72. Therefore, the first flip plate 711 may be rotatably connected to the rotation axis 72 through the first connecting plate 7113, so that the first curved plate 7111 and the first extension plate 7112 can rotate relative to the rotation axis 72 along with the first connecting plate 7113.

[0106] It should be noted that, in some other embodiments, the first connecting plate 7113 may also be arranged to protrude and extend from the first arc-shaped plate 7111 toward the direction of the rotating shaft 72 .
