(C) shows the detached state of taking out the filter, respectively.
5 is an exploded perspective view of an essential part of the air conditioner according to the present invention, FIG. 4 is an explanatory view of the air conditioner according to the present invention, FIG. 4A is a sectional view, and FIG. 6A and 6B are cross-sectional views of an essential part of the air conditioner according to the present invention. FIG. 6A shows a state in which a biasing spring presses the suction grill, FIG. 6B shows a state in which the suction grill slides, and FIG. FIG. 7 is a cross-sectional view showing a state in which the drive devices are linked, (A) shows a state in which a suction grill is attached, (B) shows a state in which the suction grill is slid forward, and FIG. 7 shows a drive for the suction grill. It is a principal part explanatory view which shows the attachment state of a motor.

As shown in FIGS. 1 (A) and 4 (A), the air conditioner according to the present invention is provided with a suction bar 4a on the upper front surface of the base 3 supporting the heat exchange device 1 and the blower fan 2. A suction port in which the suction grille 8 is slidably attached to and detached from the rear surface portion 4 and the guide portion 7 in the front-rear direction.
An upper surface panel 6 including a front surface portion 5 having a 5a is mounted, a filter 9 is detachably mounted on the rear surface side of the upper surface panel 6, and a blower outlet is provided in the lower front surface of the base 3.
The lower surface panel 11 provided with 10 is attached, and the suction port 5a
The air sucked from the air and heat-exchanged by the heat exchange device 1 is blown out from the outlet 10 to the air-conditioned room by the blower fan 2.

This type of air conditioner is called a ceiling wall type which is constructed so as to be hung on the ceiling surface of the air-conditioned room or installed on the wall surface. It has been desired that the filter 9 can be easily removed without removing the suction grill 8 near the ceiling surface of the air-conditioned room.

Therefore, the suction grille 8 according to the present invention.
Is attached to the suction port 5a of the upper panel 6 so as to be slidable forward and backward, and the filter 9 is inserted into and removed from the lower front end of the suction grille 8 slid forward. There is.

Further, as shown in FIG. 3, partition bars 12 are provided on the back surface of the suction bar 4a and on the suction port 5a so as to extend in the front-rear direction and divide these into left and right, and the suction grille 8 is provided.
And the guide portion 7 and the filter 9
The guide portion 7 is divided into right and left portions through the rail 12. The guide portion 7 corresponds to the rails 13 provided on the back side of the suction bar 4a and the suction port 5a, and the rails 13, respectively. The guide grille 14 is provided on both sides of the suction grille 8.

With the above configuration, the operation will be described below. For example, at the time of maintenance, as shown in FIG. 1 (A) and FIG. 2 (A), with the suction grill 8 mounted on the suction port 5a, the suction grill 8 close to the ceiling surface of the air-conditioned room. When removing the filter 9 without removing the filter, FIG. 1B, FIG. 2B and FIG.
As shown by (C), by sliding the suction grille 8 forward, the suction grille 8 can be removed from the lower part of the front end of the suction grille 8 as indicated by the arrow, which improves workability during maintenance.
