[0049] The working principle of the present utility model is:
[0050] When the user uses the electromagnetic cooker of the present utility model to cook food indoors, the electromagnetic heating device 6 and the oil fume suction device 30 in the tabletop housing 4 are started together. The electromagnetic heating device 6 starts to heat the container on the surface of the tabletop housing 4 and the food in the container, and the smoke extraction fan 7 starts to suck air, generating negative pressure in the smoke collection box 3. At this time, all the oil fumes generated during cooking are sucked into the air inlet 41. The oil fumes flow downward, pass through the aluminum filter screen 22, and the oil and water in the oil fumes are filtered out, then flow downward into the oil collection grooves 26 on both sides, follow the oil and water in the oil collection grooves 26 to flow downward to the oil discharge port 25, then flow downward from the oil discharge port 25 into the smoke collection box 3, and finally the oil and water in the smoke collection box 3 flow into the oil receiving cup 34 through the oil discharge holes 32. Then the filtered oil fumes pass through the activated carbon filter screen 9 again, and the smoke extraction fan 7 discharges the filtered air into the exhaust duct 8.
[0051] When the user wants to clean the aluminum filter screen 22 and replace the activated carbon filter screen 9, the user needs to first remove the air inlet grille 5, then take out the entire oil receiving filter screen device upward, then take out the activated carbon filter screen 9 upward. The user then cleans the aluminum filter screen 22, and then installs a new activated carbon filter screen 9 in the smoke collection box. The activated carbon filter screen 9 is placed on the positioning step, then the entire oil receiving filter screen device is installed downward into the air inlet 41, and finally the air inlet grille 5 is covered.
