AI Technical Summary
The heating structure of existing range hood filters is complex, resulting in complex manufacturing processes and high costs.
The frame-type heating structure is adopted, with the heating components distributed circumferentially on the frame, surrounding the filter screen. Heat is conducted to the filter screen through the frame. The heating components are separated from the filter screen, which simplifies the structure and achieves uniform heating.
The production process of the filter screen has been simplified, the cost has been reduced, and uniform heating of the filter screen has been achieved, which has improved the oil dissolution effect.
