Description

Technical Field

[0001] The utility model relates to the technical field of induction cooktops, and particularly relates to an induction cooktop. Background Art

[0002] The structure of the existing induction cooktop, such as a downdraft range hood integrated with an induction cooktop disclosed in Chinese Patent Publication No. CN210801307U on June 19, 2020, includes an induction cooktop part, a tabletop air intake part, a smoke collection and filtration part, and a smoke extraction pipe part. The smoke collection and filtration part includes a smoke collection box, a water collection tank, an oil filter screen, and a carbon box. The smoke extraction pipe part includes a connecting smoke pipe connected to the air outlet, a fan installed at the bottom of the connecting smoke pipe, and a common flue connecting pipe connected to the fan. The existing induction cooktop has the following deficiencies: First, its oil filter screen is placed obliquely, while the carbon box is placed vertically. Therefore, the disassembly and assembly of the carbon box and the oil filter screen are very troublesome and there will be obstacles. Moreover, with the carbon box placed vertically, the oil fume filtration effect is average. Second, the soup in the bowls and pots on the tabletop splashes onto the air inlet, and the soup splashes downward onto the fan, and the soup remains in the fan, which is easy to breed bacteria. Over time, there will be an odor and it is unhygienic. Third, in addition, its fan is far away from the air inlet, resulting in insufficient suction at the air inlet and poor oil fume extraction effect. Therefore, the structure of the existing induction cooktop needs to be further improved. Summary of the Utility Model

[0050] The working principle of the present utility model is as follows:

[0051] When a user uses the induction 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 a negative pressure in the smoke collection box 3. At this time, the oil fume generated during cooking is all sucked into the air inlet 41. The oil fume flows downward, passes through the aluminum filter screen 22, and the oil and water in the oil fume are filtered out, then flow downward into the oil collection grooves 26 on both sides, and then flow downward with the oil and water in the oil collection grooves 26 to the oil discharge port 25, and then flow downward from the oil discharge port 25 into the smoke collection box 3. Finally, the oil and water in the smoke collection box 3 flow into the oil receiving cup 34 through the oil discharge holes 32, and then the filtered oil fume passes through the activated carbon filter screen 9 again. The smoke extraction fan 7 discharges the filtered air into the exhaust duct 8.

[0052] 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 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, and then the entire oil receiving filter device is installed downward into the air inlet 41, and finally the air inlet grille 5 is covered.
