[0029] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, the present application first provides a multifunctional cooking device, including a device body 10 and a fume extraction structure 20 arranged inside the device body 10, the fume extraction structure 20 includes a flue 21 and a fan 22 arranged in the flue 21, the multifunctional cooking device also includes an installation box 30 and a first air duct 40 arranged inside the device body 10, a circuit board 31 is arranged inside the installation box 30 and an air inlet hole 32 is opened through the installation box 30, one end of the first air duct 40 is connected to the inside of the installation box 30, and the other end is connected to the flue 21.

[0030] In the present application, the fan 22 in the range hood structure 20 will form a strong negative pressure in the flue 21 when it is working. By setting a first air duct 40 to connect the installation box 30 and the flue 21, the air outside the installation box 30 is sucked into the installation box 30 through the air inlet 32 ​​under the action of strong negative pressure, and then sucked into the flue 21 through the first air duct 40. During this process, the airflow can exchange heat with the circuit board 31 in the installation box 30, thereby effectively reducing the temperature of the circuit board 31; the fan 22 of the range hood structure 20 is used to dissipate heat for the circuit board 31, the cost is relatively low and the heat dissipation requirements of the circuit board 31 are met.

[0031] Preferably, the first air guide duct 40 is formed by integral injection molding, which has relatively low cost, thereby further reducing equipment cost.

[0032] Please refer to Figure 2As shown, in some embodiments, the cross-sectional area of ​​the first air duct 40 on the side communicating with the installation box 30 is smaller than the cross-sectional area of ​​the side communicating with the flue 21 .

[0033] Such a design can make the wind speed of the first air duct 40 at one end of the installation box 30 higher, which is more conducive to the inhalation of external air, thereby achieving a better cooling effect.

[0034] Please refer to Figure 2 As shown, in some embodiments, the first air duct 40 is Z-shaped as a whole, and the corner position of the first air duct 40 is arc-shaped. The arc-shaped corner can have a certain flow-guiding effect and prevent the airflow from colliding and turbulent flow in the first air duct 40.

[0035] Of course, in some other embodiments, the first air duct 40 may also be in other shapes as long as it can connect the installation box 30 and the flue 21 .

[0036] Please refer to Figure 2 As shown, in some embodiments, a sealing member 50 is provided at the connection position between the first air duct 40 and the flue 21 .

[0037] Specifically, one end of the first air guide 40 is fixedly connected to the installation box 30 by screws, and the other end is inserted into the flue 21 and sealed by the seal 50 to achieve a better heat dissipation effect.

[0038] Please refer to Figure 2 As shown, in some embodiments, a connecting flange 41 is provided on the outer peripheral surface of the first air duct 40 , and the sealing member 50 is sleeved on the connecting flange 41 and tightly fits against the outer wall of the flue 21 to increase the sealing effect of the sealing member 50 .

[0039] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the multifunctional cooking device further includes a second air duct 60, one end of the second air duct 60 is connected to the installation box 30, and the other end is connected to the outside.

[0040] By setting the second air duct 60, when the fan 22 is working, the flue 21 with strong negative pressure will also inhale external cold air from the outside into the installation box 30. At this time, the heat dissipation of the circuit board 31 has two air inlet paths, thereby achieving better heat dissipation and cooling effect.

[0041] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the device body 10 includes a box body 11 and a door body 12 hinged to the box body 11, a hollow cavity 121 is opened in the door body 12 and the hollow cavity 121 is connected to the outside, and a door body heat dissipation duct 70 is also provided in the box body 11, and the door body heat dissipation duct 70 is respectively connected to the installation box 30 and the hollow cavity 121.

[0042] Specifically, one end of the second air duct 60 is inserted into the installation box 30, and the other end is connected to the door heat dissipation duct 70 by adhesive; when the fan 22 is working, the two air inlet paths are:

[0043] 1. Air inside the device body 10 → air inlet 32 ​​→ mounting box 30; and,

[0044] 2. External cold air → hollow cavity 121 in door body 12 → door body heat dissipation air duct 70 → second air duct 60 → installation box 30.

[0045] In some embodiments, the door body heat dissipation air duct 70 is also connected to the flue 21; when the fan 22 is working, the strong negative pressure in the flue 21 will pass through the door body 12 and the door body heat dissipation air duct 70 to suck the external cold air into the flue 21. In this process, due to the suction effect of the first air duct 40 on the installation box 30, part of the cold air in the door body heat dissipation air duct 70 will enter the installation box 30 via the second air duct 60, so as to increase the air flow entering the installation box 30 through the second air duct 60, thereby obtaining a better cooling effect.

[0046] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, one end opening of the door body heat dissipation duct 70 is connected to the flue 21, and the other end opening is connected to the hollow cavity 121 when the door body 12 is closed, and the opening of the door body heat dissipation duct 70 connecting to the second air duct 60 is located between the two end openings.

[0047] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the first air duct 40 and the second air duct 60 are arranged opposite to the connection port of the installation box 30; so as to increase the air suction effect of the first air duct 40 on the door body heat dissipation air duct 70, so that more cold air flow in the door body heat dissipation air duct 70 can enter the installation box 30 along the second air duct 60.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
