The smoking case 14 is installed on the upper sliding frame 1308;

[0038] A decorative cover 19 is embedded at the upper end of the notch 4.

[0039] Working principle: Oil fume inhalation:

[0040] The smoke extraction shell 14 can be lifted and adjusted according to cooking needs under the control of the lifting mechanism 13. When cooking is required, the reduction motor 1307 can be used to drive the screw rod 1306 to rotate, driving the push plate 1305 and the cross rod 1303 to move, thereby driving the smoke extraction shell 14 to rise; conversely, after cooking, the smoke extraction shell 14 can be driven to descend for storage.

[0041] When cooking generates oil fumes, the first motor 5 drives the wind wheel 6 to rotate, generating a strong suction force. The airflow generated by the rotation of the wind wheel 6 is guided by the air guide shell 7 to form a negative pressure area. This negative pressure area acts on the oil fumes above the stove, causing them to be sucked into the smoke extraction shell 14.

[0042] Oil fume filtration:

[0043] After the oil fumes are sucked into the smoke extraction shell 14, they are first preliminarily filtered by the filter ring 12. The filter ring 12 is driven by the second motor 11 to rotate, which can effectively intercept large particles of oil fumes and oil droplets.

[0044] The preliminarily filtered oil fumes continue to flow downward, enter the second side shell 20 through the air guide shell 7. Inside the second side shell 20, there is a water tank 21, and inside the water tank 21, there is a filter grille 22. The filter grille 22 can adsorb the passing oil fumes, and at the same time, the water source in the water tank 21 can also adsorb part of the oil fumes. After that, the oil fumes adsorbed and filtered by the components inside the second side shell 20 enter the first side shell 16. Inside the first side shell 16, there is an activated carbon filter element 18. Activated carbon has a strong adsorption capacity and can further adsorb the fine particles and harmful gases in the oil fumes to achieve deep filtration.

[0045] Preferably, the water tank 21 and the activated carbon filter element 18 of this stove can be customized according to customer needs, or a single filter component can be customized and installed, so as to achieve multiple ways of filtering oil fumes.

[0046] Oil fume discharge:

[0047] The clean air after deep filtration is discharged outside the stove through the air outlet 17 at one end of the first side shell 16, so as to keep the air in the kitchen fresh; preferably, the air outlet 17 can be connected to a pipeline for discharging the gas outdoors.

[0048] Cleaning and maintenance:

[0049] To keep the stove clean and the filtering effect, the user can regularly disassemble the side plate 15. The water tank 21 and the activated carbon filter element 18 are both designed with a handle-pull-out structure, and the water tank 21 and the activated carbon filter element 18 can be pulled out for cleaning or replacement. At the same time, the filter ring 12 and other components inside the bottom shell 1 can also be cleaned as needed.

[0050] In summary, through its unique design and working principle, this under-mounted range hood with multi-functional stove realizes the efficient suction, filtration, and discharge of oil fumes. This design not only improves the convenience and comfort of cooking but also effectively protects the kitchen air quality and user health.
