Portion of ventilation fan grille

Abstract

【Item Uses】 This design is part of the outer cover of a ventilation fan, particularly for use in, but not limited to, warm air ventilation fans. 【Design Description】 This design is a component of an exhaust fan cover. Viewed from the perspective and side views, the exhaust fan cover has a rectangular outline and a double-layer design consisting of an outer layer and an inner layer. The outer and inner layers are spaced apart to form a side airflow channel. Viewed from the side views, the outer layer has multiple rectangular openings on its front, with an outwardly sloping curved surface around its perimeter. The inner layer has a sloping side; its outer contour is slightly smaller than that of the outer layer. This design possesses a unique, simple, and clean-cut shape, presenting a novel and distinctive visual effect from all views. The dotted lines in the drawings represent the parts that are not recommended for design in this case. Exploded view diagrams 1 and 2 in the drawings show the separation of the upper and lower covers of this design; the exploded view reference diagram in the drawings shows the separation of the upper and lower covers of the ventilation fan and the main body of the heater in this design.
