AI Technical Summary
Existing air fryers have limited motor heat dissipation capacity, making them prone to damage during prolonged high-load operation. Furthermore, the steam and excess heat in the heating chamber are not efficiently expelled, affecting the taste of food and heating efficiency.
It adopts a dual-fan design, with the cooling fan located at the top of the motor. The cooling airflow is introduced and driven by the entrainment effect to expel the high-temperature airflow, thereby enhancing the heat dissipation of the motor and the exhaust efficiency of the heating chamber.
It effectively reduces motor temperature, improves exhaust efficiency of the heating chamber, maintains appropriate cooking temperature and environment, and enhances equipment operation stability and safety.
