[0031] The shell 100 may be made of alloy material and may be disc-shaped. Specifically, the top view of the shell 100 may be circular or rectangular, etc.

[0032] It is understood that the induction cooker of this utility model can be used with a pot body 500 having an airflow duct 530, such as Figure 2As shown, the pot body 500 is placed on the upper surface of the shell 100. The electromagnetic module 200 generates an alternating magnetic field, which cuts the pot body 500, causing it to heat up and thus cooking the food inside. The shell 100 is equipped with an exhaust duct 150. The tail end of the exhaust duct 150 is used to connect to the exhaust fan 400, while the head end of the exhaust duct 150 is connected to the first vent 160 located on the upper surface of the shell 100. The first vent 160 can be connected to the air guide duct 530. When the exhaust fan 400 is running, airflow is formed in the air guide duct 530 and the exhaust duct 150, thereby removing the steam and fumes generated during cooking. This design is compact and does not easily obstruct the user's activities. It is easy to cooperate with the exhaust fan 400 for ventilation, improving the user's cooking experience.

[0033] In some embodiments of this utility model, such as Figure 1 , 2 As shown, the exhaust duct 150 runs through the upper and lower surfaces of the housing 100. The induction cooker can be embedded in the tabletop. There is sufficient space under the table to accommodate the exhaust fan 400.

The bottom end of the guide air duct 530 can be connected to the first end of the exhaust pipe 150 through a first vent 160.

[0048] Food can be placed in the cooking recess 510. The top of the guide column 520 is usually higher than the opening of the cooking recess 510. The food in the cooking recess 510 will not flow directly into the guide air duct 530. During the cooking process, oil fumes and steam rise. When they rise to the top of the guide column 520, they can be drawn into the guide air duct 530 and the exhaust pipe 150 by the airflow guided by the exhaust fan 400.

[0049] This utility model of cooking device allows an induction cooker to be used in conjunction with a pot body 500 having a guide air duct 530. When the exhaust fan 400 is running, airflow is formed in the guide air duct 530 and the exhaust pipe 150, thereby removing the steam and fumes generated during the cooking process. This design is compact and does not easily obstruct the user's activities. It is easy to work with the exhaust fan 400 to remove fumes, thus improving the user's cooking experience.

[0050] The technical features of the above embodiments can be combined in any way.
