<Front panel and decorative panel>
The arrangement of the front panel 2 and the decorative panel 3 will be described. The protrusion 25 of the front panel 2 is disposed on the inner side of the flange 31 of the decorative panel 3. As shown in FIG. 6, the flange end surface 31 a on the front panel 2 side of the flange 31 of the decorative panel 3 is arranged at the same position or the lower side in FIG. 6 with respect to the edge 21 of the front panel 2.
The distance between the flange end surface 31a and the bottom surface portion 22 is a distance T1, the distance between the back surface 3c of the decorative panel 3 and the protruding surface 25a of the front panel is a distance T2, and T1≈T2. By setting T1≈T2, it is possible to avoid a possibility that noise is generated and a suction amount is reduced because the flow of the air S becomes narrower and becomes faster than either T1 or T2.

  Next, an imaginary line 50 that connects the flange end surface 31a of the flange 31 of the decorative panel 3 and the intersection 25c of the protruding surface 25a of the front panel and the protruding portion inclined surface 25b is set. The virtual line 50 is set so as to form an angle X with the reference 51 provided parallel to the front surface of the decorative panel 3 and on the same plane as the virtual line 50. The angle X is preferably about 45 ° or less. When the angle is 45 ° or less, the flange 31 of the decorative panel 3 covers the front of the protrusion 25 of the front panel 2 and only the flange 31 and the protrusion 25 can be seen, regardless of the angle at which the side air inlet 23a (23b) is viewed. The suction port 23 is not visually recognized. On the other hand, when the angle X is set to 60 degrees, when looking into the side air inlet 23a (23b), the flange 31 of the decorative panel 3 is not covered in front of the protrusion 25 of the front panel, and the suction port 23 is visible. Will come to be.

With the above configuration, the air S taken in from the side air intake port 23a (23b) is continuous at the concave inclined surface 20a, the bottom surface portion 22, the protruding portion inclined surface 25b, and the protruding surface 25a of the front panel 2. The air flows into the suction port 23 along the air flow path P having a gently curved surface.
On the decorative panel 3 side, a distance T1 between the flange end surface 31a of the flange 31 of the decorative panel 3 and the bottom surface portion 22 of the front panel, and a distance T2 between the back surface 3c of the decorative panel 3 and the protruding surface 25a of the front panel are T1≈T2. By being configured in this way, the air is not partially narrowed and a sufficient air flow path width can be secured, and the sucked air S flows smoothly into the suction port 23. Therefore, even if the protrusion 25 is provided around the suction port 23, a sufficient amount of air S can be secured by the configuration in which the air S is transmitted through the back surface 3 c of the decorative panel 3.
And the virtual line 50 which connects the flange end surface 31a of the flange 31 of the decorative panel 3 and the intersection 25c of the protrusion surface 25a of the front panel and the protruding portion inclined surface 25b is parallel to the front surface of the decorative panel 3 and is identical to the virtual line 50. Since the reference 51 provided on the plane is at an angle of about 45 ° or less, the flange of the decorative panel 3 can be seen from the side-side air inlet 23a (23b) as shown in FIG. The appearance of the suction port 23 and the prefilter 40 attached to the suction port 23 are not visually recognized only by seeing 31 and the protruding portion 25 of the front panel 3, and the aesthetics are improved.

  Further, the upper surface side air intake port 23c and the bottom surface side air intake port 23d pass through the gap between the protruding surface 25a of the front panel 2 and the upper and lower curved surface portions 3a and 3b of the decorative panel 3, respectively. In addition, the pre-filter 40 is not visually recognized because the curved surfaces 3a and 3b above and below the decorative panel 3 and the protruding surface 25a of the front panel 2 have a depth.
