Vibrating Grill Assembly for Debris Removal

The patent applies mechanical vibration through a motor-driven vibration mechanism that vibrates the air inlet screen at specific frequencies. This vibration dislodges debris particles accumulated on the screen surface, preventing blockage and maintaining continuous airflow. The vibration mechanism is integrated into the grill assembly structure, with the motor mounted on the trusses that support the air inlet screen.

The patent implements a self-service cleaning system where the vibration mechanism automatically cleans the air inlet screen without human intervention. The motor-driven vibration operates periodically or continuously to self-remove debris accumulation, allowing the machine to maintain optimal cooling performance throughout extended operational periods without requiring operator attention for screen cleaning.

The vibration mechanism compensates for the increased debris accumulation surface area by actively dislodging particles from the entire screen surface. The mechanical vibration ensures that even with a larger screen area providing greater airflow capacity, debris does not accumulate to blocking levels because the vibration continuously prevents particle adhesion and promotes particle detachment.

The vibration mechanism allows the use of finer mesh screens for better debris filtration by preventing the finer particles and dust from accumulating on the screen surface. The vibration keeps the screen surface clear, maintaining high airflow rates even with fine mesh configurations that would otherwise clog quickly, thus resolving the trade-off between filtration effectiveness and airflow rate.
