FIG. 5 is a cross-sectional view of the hooking / releasing mechanism for explaining a state immediately before the suction grill is fitted into the suction port. As the hanging mechanism S, a horizontal piece Ka of an inverted L-shaped grill catcher K is attached and fixed to the end of the decorative panel 7 on the suction port 10 side through a fixture c. The vertical piece Kb of the grill catcher K extends into the suction port 10, and a fixed claw T is integrally formed at the tip.

It has a substantially key-shaped cross section. The plate thickness of the vertical piece Kb of the grill catcher K is relatively thin, and therefore elastically deformable, so that the position of the fixing claw T is relatively easily changed. At the peripheral end of the suction grill 14 is provided an opening d into which the fixed claw T of the grill catcher K can be inserted. The grill claw G is opposed to the opening d.

Retained. In order to open the suction grill 14 at the time of maintenance on the filter, the fixed claw portion T of the grill catcher K is pressed and urged in the direction a indicated by the two-dot chain line arrow in FIG.

前の状態を示している。The grill catcher K is elastically deformed as shown by the chain double-dashed line so that the fixed claw portion T is separated from the grill claw portion G, and the suction grille 14 is rotatable about a hinge mechanism (not shown) as a fulcrum. In FIG. 5, the suction grille 14 is rotated after the maintenance work is completed, and the decorative panel 7 is again rotated.
It shows a state immediately before being completely fitted when being fitted into the suction port 10.

Due to the difference in the rigidity of the claw portions and the shape thereof, the grill catcher K is pushed by the grill claw G and elastically deformed as shown in the figure, and the position of the fixed claw T is displaced. When the suction grille 14 is pushed further upward, the tip of the grille claw G slides on the inclined surface of the fixed claw T and finally gets over. When the lifting force is removed while the suction grill 14 is completely pushed into the suction port 10, the grill claw G and the fixed claw T are engaged again.

Must be considered.
Due to various other changes in the conditions, the state in which the horizontal surface portion f of the fixed claw portion T is locked to the engaging concave portion e of the grille claw G is likely to be affected, and thus the support of the suction grille 14 may become unstable. .
